Fixing device for main engine of machine-room-free elevator

Abstract

The invention discloses a fixing device for a main engine of a machine-room-free elevator in the technical field of machine-room-free elevators. The fixing device comprises a tractor main engine and afixing installation box base. Main engine installing feet of bilateral symmetry are arranged on the bottom of the tractor main engine. An inner cavity of the fixing installation box base is providedwith buckle fixing plates in a bilateral symmetry manner. Semi gear plates are connected to the bottoms of the buckle fixing plates. A fixing sliding base, a movable sliding bar and a moving rack arefixedly arranged on the bottom of the inner cavity of the fixing installation box base. The top of the fixing installation box base is sunken downwards to form a spring storing groove. An inner cavityof the spring storing groove is provided with a lifting rod. The outer wall of the lifting rod is provided with a jacking spring in a sleeved manner. A sliding groove plate is fixedly connected to the bottom end of the lifting rod and provided with a sliding groove. Rolling wheels are arranged in an inner cavity of the sliding groove in a sliding manner. The rolling wheels are installed on a rolling wheel support in a clamped manner through a rolling wheel shaft. The rolling wheel support is fixedly arranged at the right end of the movable sliding bar. The fixing device for the main engine ofthe machine-room-free elevator is convenient to maintain, assemble and disassemble, and prevents loosening faults.

Description

technical field [0001] The invention relates to the technical field of machine room-less elevators, in particular to a machine room-less elevator main engine fixing device. Background technique [0002] In recent years, the development of the elevator industry has changed from machine-room elevators to machine-room-less elevators. Machine-room-less elevators are controlled by frequency conversion and speed-adjusting microcomputers, which are quite different from previous vertical elevators in structure. In order to save space, the machine room-less elevator installed the control cabinet, main engine, speed limiter and other equipment installed in the machine room above the hoistway instead of the machine room. construction cost. The transportation is realized by using the miniaturized gearless main engine and the 2:1 traction system, which eliminates the noise in the machine room caused by the traditional gear meshing; the thin control cabinet is installed in the shaft near...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a machine room-less elevator main engine fixing device to solve the above problems. At present, the main machine traction machine of the machine room-less elevator is still installed by directly fixing bolts. Vibration, this way of directly fixing the bolts is prone to loosening under the direct action of the vibration of the traction machine. Over time, it is easy to cause the installation of the traction machine to be unstable and loose, which affects the personal safety of elevator passengers; It is necessary to screw each bolt one by one for disassembly, cumbersome operation and low efficiency
