Gaobeidian2 to
GaobeidianElecMechanical devices controlled by cage movement should not be used to open or close the landing door.
The foundation base or embedded parts should be fully embedded in the concrete foundation plate.
Gaobeidian.The top of the hanging cage is accessible; d) During installation/disassembly/maintenance/inspection of the device; e) Inside the hanging cage.
Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, shallow foundation pit required, large stroke, stable operation, low noise accurate positioning, and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table, it can be stopped arbitrarily within the range of travel.
.Monthly maintenance and inspection of hydraulic lifting platform rollers, intermediate shafts and bearings, oil cylinder pin shafts and bearings, boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process, and at this position, the hydraulic ground should be 40-50 millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky, or has foreign objects such as gravel, it should be replaced in a timely manner (32 # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged, and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform, blow out the plunger with compressed air, then install it and reinstall it. Drain and discard the hydraulic oil, tighten the joint, remove the oil filter,GaobeidianNiuli brand electric elevator, clean it with compressed air and then return it to the oil tank and connect the pipeline.
The quality of the standard section should comply with the product manual and specification requirements.
When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.
Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).
That's all for a brief introduction to the common types of electric elevators. I hope everyone can have a better understanding of this product. Currently, this product is selling well in China, as many places need to use this type of product that has both lifting function and flexible movement. Companies specializing in producing this type of product are now promoting it on a large scale through the internet, performance, and price information of these products. They can purchase directly through the internet.
In addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between 1m and 2m. And there should be at least protective railings, a half height middle crossbar, and a toe board at least 150mm above the ground.
index.Then, the lifting platform platform platform that carries the load needs to be balanced, and the lifting of goods should try to maintain a stable and uniform speed.
The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.
Mechanical devices controlled by cage movement should not be used to open or close the landing door.
Use floor doors and cage door devices on construction sites where conditions permit.
Honesty is the foundation.Before installation, embedded parts foundation bearing capacity, and foundation drainage measures of the installed construction electric elevator and auxiliary heavy equipment comply with the requirements of the special construction plan for the installation and dismantling of the construction electric elevator based on the construction electric elevator foundation acceptance form, concealed engineering acceptance form, and concrete strength report.
The safety overtravel of limit switches and upper limit switches should comply with regulatory requirements.
Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descent
Gaobeidian.The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve,GaobeidianInstallation of electric elevators for fire protection, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).
The counterweight guide rail should meet the specification requirements.
Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient, and the valve can be opened and closed at any time; The installation of a rotary valve reduces the friction of the sealing components; Compact structure, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
