Problems solved by technology

The braking deceleration force brought by this protective mechanism acts concentratedly on the top of the main body of the elevator car, which makes the overall stress on the main body of the car uneven, the deceleration effect is poor, and the contact position between the protective mechanism and the side wall of the elevator shaft is stressed. If it is too large, it is easy to cause damage and cause the protection mechanism to fail

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] see Figure 2-Figure 5 , in an embodiment of the present invention, an elevator car safety protection mechanism includes a car main body 1, the car main body 1 is slidably connected in the elevator shaft 2, and the inner wall of the elevator shaft 2 is provided with a plurality of limit slide grooves 3, and the car body 1 The outer wall of the box main body 1 is provided with several docking buffers, which are slidably connected in several limiting slid...

Abstract

The elevator car safety protection mechanism comprises a car main body, the car main body is connected into an elevator shaft in a sliding mode, a plurality of limiting sliding grooves are formed in the inner wall of the elevator shaft, and a plurality of butt joint buffering pieces are arranged on the outer wall of the car main body; a plurality of butt-joint buffering pieces are slidably connected into the limiting sliding grooves correspondingly, each butt-joint buffering piece comprises a buffering abutting-pushing block, and an electromagnet is fixedly installed in the middle of each buffering abutting-pushing block; iron sheets are adsorbed through magnetic force generated when electromagnets are powered on, then friction force is generated to achieve deceleration buffering of the lift car body, the deceleration effect is more uniform, meanwhile, counter-acting force generated by deceleration of the lift car body is borne by all the buffering abutting-pushing blocks in a dispersed mode, abrasion to the single buffering abutting-pushing block is small, and the service life of the lift car body is prolonged. And the service life is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of elevator related equipment, in particular to an elevator car safety protection mechanism. Background technique [0002] During the use of the elevator, it is easy to slide or slide due to various failures, which endangers the safety of passengers, so it is necessary to set up a safety protection mechanism. [0003] Such as figure 1 Shown is an elevator with a safety protection mechanism, which brakes and decelerates the main body of the motor car through the contact friction between the protection mechanism and the side wall of the elevator shaft when the elevator fails through the protection mechanism arranged on the top . The braking deceleration force brought by this protective mechanism acts concentratedly on the top of the main body of the elevator car, which makes the overall stress on the main body of the car uneven, the deceleration effect is poor, and the contact position between the protective...
