Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.

The selection of vibration pickup points refers to the placement point of the sensor, which is used to measure the vibration amplitude of the workpiece. According to GB/T25712-2010, the acceleration sensor should be placed on the workpiece with a certain rigidity and a large amplitude, the vibration pickup point is set in a thick area in the middle of the component.

Valpalota.The frequency conversion system circuit of the construction elevator is mainly composed of two parts: the main circuit and the circuit. The main circuit mainly consists of a construction lifting cargo elevator (hereinafter referred to as the lifting cargo elevator) driven by a more complex rectifier. Before installation, all the eccentric roller shafts of the lifting cage and driving mechanism are loosened or adjusted to a large eccentricity, power on the suspension cage until it rises 1m above the ground or detaches from the ground buffer spring (or support) and the two are connected. Starting from adjusting the driving mechanism, the adjustment and sequence are as follows: 1. Use a special wrench to rotate the lower double (single) pendulum eccentric shaft to adjust the eccentricity to maintain the installation surface of the mechanism perpendicular to the horizontal plane, and make the upper and lower pendulum wheels evenly guide the rails at the same time. Rotate each wheel body by hand to check if it evenly presses the rails; 2. Use a special wrench to rotate the eccentric shaft of the gear rack back pressure wheel to adjust the side clearance during gear rack meshing. When adjusting, use a feeler gauge to measure the side clearance to 0.2; Between 0.5mm, each pressing wheel should evenly press on the back of the rack. Move each wheel body by hand to check if it evenly presses against the tooth back. Similarly, adjust the guide rollers on both sides of the guide rail. The adjustment key is to adjust the guide wheel on one side of the guide rail to lightly press it onto the guide rail. When moving the wheel body by hand, it should be possible to rotate but there should be obvious obstruction; The roller on the other side should maintain a clearance of 0.2-0.5 ram with the guide rail; 4. Adjust the lifting cage according to the above and sequence. If the driving mechanism and the lifting cage are integrated into the lifting cargo elevator, the lifting cage should be adjusted according to the and sequence of adjusting the driving mechanism. Conduct a visual inspection of the operation of each roller, and use the lead pressing method and coloring method to check the meshing of the gear pair; Fine tune 6 pairs of unsatisfactory parts. The key point is to carefully adjust the meshing status of the gear pair: when the spots shown in 1 appear on the surface of the gear rack, it indicates that the driving mechanism is tilted towards the side of the guide rail. At this time, the lower swing wheel (single or double wheel) should be adjusted to move the lower part of the driving mechanism towards the direction of the guide rail until the area of the spots reaches more than 85% of the surface of the gear rack. The smaller the area, the easier it is to damage the gears and racks.

Now with the arrival of summer, the aluminum alloy lifting platform will certainly suffer from high temperature and rainstorm in summer. It is easy to rust after a long time under this condition, which will seriously shorten the service life of the equipment and cause safety problems. So how should we prevent equipment rust?

.Jinchuang lifting platform product feature 01 is mainly used for high-altitude cargo transportation between floors. With a load capacity of 1-50 tons and a lifting height of 1-25 meters, a guide rail elevator, also known as a hydraulic elevator, can be installed indoors and outdoors.

Low failure rate: Due to the use of advanced hydraulic systems and good methods, the failure rate of elevator operation can be minimized. Low power consumption: When the hydraulic elevator descends, it is driven by the pressure generated by its own weight, which greatly saves energy.

According to calculations, when the support points of the beam type components are located along the length of 1/9L on both sides, the vibration resistance is relatively small, making it easy to obtain resonance and vibration effects with larger amplitudes. The geometric shape of the structure on the lifting foundation is similar to a long beam type component, and the structure is complex. Therefore, the structural shape is complex, and residual stress is inevitably generated during the manufacturing process. In order to prevent deformation of the components due to changes in residual stress during use,ValpalotaGuide rail type lifting platform for factory use, it is necessary to perform stress relief treatment on the completed components.

Respect for customers.The safety control voltage of 18 is selected with rolling guide shoes, high accuracy, wear resistance, and stable lifting. The characteristics of the Jinchuang lifting platform are as follows: 1. There is no need for a machine room above the shaft. 2. The hydraulic elevator is not equipped with a counterweight device to improve the utilization rate of the shaft area. 3. The load and load cylinder of the hydraulic elevator directly act on the foundation pit, and the strength requirements of the shaft are low, Brick or brick concrete structure hoistway can be used for Jinchuang lifting platform safety and stability advantages. Overflow valve: It can prevent system pressure from being too high during upward movement. Emergency manual valve: In case of power failure, it can make the elevator emergency descend to the nearest floor position and open the door.

According to GB/T25712-2010, when one of the following situations occurs in the curve related to the aging frequency, it can be determined that the area covered by the effective zone of the vibration mode at that frequency has reached the aging effect: the curve rises and flattens; The curve rises, then falls, and then flattens; The resonance frequency of the a-n curve after vibration is lower than that before vibration; The bandwidth of the a-n curve after vibration narrows compared to before vibration; The resonance peak of the a-n curve after vibration exhibits fission phenomenon; The curve flattens out after descent.

The arrangement of vibration points should be based on the vibration aging process standard GB/T25712-20. The vibration aging exciter should be placed at a position with high rigidity and amplitude of the workpiece, and its rotating axis should be parallel to the plane where the effective zone of the vibration mode is located. The exciter should be fixed at the end angle or edge of the workpiece with high rigidity, so that small energy can be used to excite the component with large amplitude. Based on the structural shape of the foundation, we set the vibration points on the protruding plates on each side of the workpiece.

It is easy to rust after a long time under this condition, which will seriously shorten the service life of the equipment and cause safety problems. So how should we prevent equipment rust?

how much.The selection of vibration pickup points refers to the placement point of the sensor, which is used to measure the vibration amplitude of the workpiece. According to GB/T25712-2010,ValpalotaFour wheel mobile scissor fork lifting platform, the acceleration sensor should be placed on the workpiece with a certain rigidity and a large amplitude, and its testing direction should be adjusted to be perpendicular to the plane where the effective zone of the vibration mode is located. Considering the complex structure of the lifting foundation workpiece and the uneven thickness of each component, the vibration pickup point is set in a thick area in the middle of the component.

The lifting stage can provide real-time information on the operation of the entire vehicle, avoiding relying solely on the experience of operators to coordinate with each other and improving the reliability and safety of the system. The definition of safety zone is very important because the lifting stage has a large range of movements, the ground turntable and the high-altitude work bar. However and it must be accurately calculated. The lifting stage has two structurally separate systems, for various movements on the vehicle, it is also an interconnected system, which needs to consider the priority of operation, and safety assurance of actions.
