Embodiment Construction

[0018] In order to more clearly illustrate the function and installation position of the present invention in the elevator, it is necessary to combine figure 1 Briefly describe the structure of the elevator.

[0019] exist figure 1 In the machine-room-less elevator shown, the car 101 runs up and down along the car guide rail 106, the counterweight 104 runs up and down along the counterweight guide rail 107, the suspension device 105 connects the car 101 and the counterweight 104, and the driving device 102 utilizes the driving wheel 103 drives the car 101 and the counterweight 104 to run in the hoistway 110, the elevator car descending safety gear 111 is installed at the lower end of the car 101, and the traditional buffer 112 is installed at the bottom of the hoistway 110.

[0020] A preferred implementation of the present invention is a one-way mechanism similar to an elevator safety gear. When the elevator car or the counterweight goes down, the action of the brake device...

Abstract

The invention discloses an elevator buffer which comprises a brake apparatus and a trigger mechanism, wherein the brake apparatus comprises a clamp body and a fixed part; the clamp body is installed in a lift car, a counter poise or a component related to the lift car and the counter poise, and moves along with the lift car or counter poise of the elevator; the fixed part is installed in a fixed position in the lift way of the elevator and does not move along with the lift car or counter poise of the elevator; the trigger component of the trigger mechanism is fixedly installed in the lift way of the elevator; and when the lift car or counter poise of the elevator moves downwards to reach or exceed the lowest parking position for normal operation., the trigger mechanism triggers the brake apparatus to move, the clamp body and the fixed part of the brake apparatus rub each other so as to slow down or stop the down-going lift car or counter poise. The invention can satisfy the requirements for elevator buffers in the national standard and reduce the quantity of elevator buffers used in the elevator, thereby saving resources.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator buffer capable of protecting the safety of an elevator running in a bottom space. Background technique [0002] In order to minimize the personal injury when the elevator car stalls or the car hits the bottom pit, the national standard GB7588-2003 stipulates that the elevator must be equipped with car safety gear and car buffer. [0003] In order to implement this standard, spring buffers, hydraulic buffers and polyurethane buffers are mostly used in the elevator industry, and there are many studies on these types of buffers, but there is little research on friction brake buffers. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an elevator buffer that can meet the requirements of national standards for elevator buffers, reduce the number of elevator buffers used in elevators, and save resources. [0005] In order...
