With the rapid development of the national economy, construction lift platforms have begun to play a huge role in more and more construction fields, and elevator customers at home and abroad have higher and higher requirements for the use of lift tables. Many high-rise buildings and factories transport building materials and When carrying goods, a construction hoist with a larger carrying capacity is required, and a construction hoist with good stability, fast running speed, low cost and high safety performance is required. In order to prevent the platform from falling, the existing construction hoist adopts a reducer to mesh with the rack of the guide rail frame. To make the cage decelerate and stop, but the output gear of the existing reducer is a single gear, and the single gear is meshed with the rack of the standard section and then the speed is limited. This deceleration method cannot withstand the heavy lifting platform due to the centralized transmission of force. , the speed limiter bears less braking load through the single-tooth reducer. Therefore, for a single-column construction lift with a large load capacity, it is obvious that this type of reducer cannot increase the braking load, which limits the load capacity of the lifting platform.
The construction aluminum lift tables with reducer produced by our company can disperse the braking force, reduce the stress concentration, and increase the braking load. It is suitable for single-column construction lift tables with large capacity and heavy load. Construction lifts, including lift platforms for loading people or goods, guide rail frames composed of standard sections, a reducer is installed under the lift platform, the reducer is provided with double output gears, the double output gears of the reducer and the rack on the guide rail frame Meshing, the number of teeth of the output gear is 12, and the modulus is 8. Wherein, the reducer also includes a box body, a follower gear and a reduction gear, the follower gear and the reduction gear are placed in the box body, and the follower gear and the reduction gear are meshed. The guide rail frame composed of standard sections is provided with double racks, the double output gears of the reducer are respectively meshed with the racks, and the reducer case body is welded by steel plates. For single-column construction elevators, the output end of the reducer is output by double output gears, so that the force is dispersed and transmitted, stress concentration is reduced, and greater force can be guaranteed. At the same time, the speed limiter of the single-column construction elevator cage passes through the reducer when falling The rated braking load is increased. After being tested and used in the operation of the single-column construction elevator, the speed limiter can increase the rated braking load by 1.4 times through the reducer.
