Abstract

The invention discloses a building construction safety elevator. The building construction safety elevator comprises a gear and a rack matched with the gear in a meshed mode and further comprises a driving buffer chain combination, the driving buffer chain combination comprises a parallel hinge four-rod mechanism, main chain wheels, a chain and a spring damping rod, the spring damping rod is located in the parallel hinge four-rod mechanism and is vertically distributed, and the two ends of the spring damping rod are correspondingly and rotatably connected with two opposite hinge shafts on theparallel hinge four-rod mechanism. According to the building construction safety elevator, the parallel hinge four-rod mechanism is arranged, the main chain wheels are connected to the four hinge shafts of the parallel hinge four-rod mechanism, the chain is engaged with the four main chain wheels, the lowest main chain wheel is connected with the gear, specifically, a reinforcing shaft is arrangedon one side of the main chain wheel, one end of the reinforcing shaft is fixedly connected with one side of teeth on the gear, when lifting is conducted, loads borne by the teeth on the gear are mainly borne by the main chain wheels, and therefore the phenomenon of tooth breaking can be avoided.

Description

technical field

[0001] The invention relates to the technical field of elevators for building construction, in particular to a safety elevator for building construction. Background technique

[0002] The construction elevator, also known as the construction elevator for construction, is a construction machine often used in construction for carrying people and goods. The current elevator adopts rack and pinion transmission, and a steel structure derrick is built outside the building. The rack is fixed on the frame, and the elevator drives the reducer through the motor. Drive the gear to rotate, the gear and the rack mesh, and then passively realize the up and down movement of the lifting box.

[0003] However, due to the high frequency of use of the lift and the heavy load of the lift box, in order to increase the power input of the lift box, the gears are small in size, which is prone to broken teeth, which directly affects the use of the lift box. In the case of continuous...
