Problems solved by technology

Due to the power limit of its traction main engine, if the rated load capacity of the freight elevator is to be increased, the rope winding ratio will be increased. However, with the increase of the rope winding ratio, many mechanical structural problems are accompanied by uneven force, The reduction in transmission efficiency and the short life of the steel wire rope lead to high equipment costs and subsequent maintenance costs

Embodiment Construction

[0018] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be more clearly defined.

[0019] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a co-existence of an intervening component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a co-existing centered component. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for illustrative purposes onl...

Abstract

The heavy-load freight elevator comprises a lift car, a bearing seat and a synchronizing shaft rotationally connected with the bearing seat are arranged at the top of the lift car, the synchronizing shaft extends to the two sides of the lift car, chain wheels are arranged at the two ends of the synchronizing shaft correspondingly, upper tensioning wheels are arranged above the chain wheels, and lower tensioning wheels are arranged above the chain wheels. A lower tensioning wheel is arranged below the chain wheel; an upper chain fixing device corresponding to the chain wheel is arranged at the top of the elevator shaft, a lower chain fixing device corresponding to the chain wheel is arranged at the bottom of the elevator shaft, a chain is arranged between the upper chain fixing device and the lower chain fixing device, and the chain is sequentially meshed with the upper tensioning wheel, the chain wheel and the lower tensioning wheel. Traction main machines are arranged on the two sides of the lift car correspondingly, and the traction main machines drive the lift car to reciprocate up and down along the chain. The double-motor driving and chain wheel and chain meshing structure improves the operation synchronism of the two sides of the lift car, the symmetrical structure on the two sides enables the lift car to operate more stably, and the load capacity of an elevator is improved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a high-load freight elevator. Background technique [0002] The structure of the traction freight elevator in the elevator industry is usually driven by a single traction main engine and the winding ratio is 2:1, and its conventional load is 3 tons and 5 tons. Limited by the power of its traction main engine, if the rated load of the freight elevator is to be increased, the rope winding ratio will be increased. The reduction of transmission efficiency and the short service life of the steel wire rope lead to high equipment costs and subsequent maintenance costs. At present, the load capacity of large-load traction freight elevators on the market is limited to between 10 tons and 20 tons. For the market application requirements of traction freight elevators with larger loads, if there is a technical bottleneck in the use of the above conventional solutions, it is necessary to ...
