Mechanical energy-consumption-type buffer

Abstract

The invention relates to a mechanical energy-consumption-type elevator buffer. The mechanical energy-consumption-type buffer is characterized by comprising a bottom plate, a guide rod, fixed plates, dead-soft steel energy-consumption dampers, a force guiding groove pipe and a top plate, wherein the guide rod is vertically fixed on the bottom plate; the force guiding groove pipe is movably sheathed on the guide rod; the at least three fixed plates are circumferentially and uniformly distributed at the periphery of the guide rod and are vertically fixed on the bottom plate; each fixed plate is correspondingly connected with one end of one dead-soft steel energy-consumption damper; the other end of each dead-soft steel energy-consumption damper is connected with the force guiding groove pipe; and a top plate for bearing the bottom of an elevator car is fixed at the top end of the force guiding groove pipe. The mechanical energy-consumption-type buffer has a simple, ingenious and reasonable structure; and the mechanical energy-consumption-type buffer is arranged under the lifting elevator car and is fixed on the ground by the bottom plate, the upper end of the mechanical energy-consumption-type buffer transfers impact force by virtue of the force guiding groove pipe, and collision energy is uniformly and stably absorbed by deformation of the dead-soft steel energy-consumption dampers, so that the impact to the elevator car and passengers is relieved, and thus the elevator car and the passengers are protected.

Description

technical field [0001] The invention relates to an energy-absorbing safety collision device applied to an elevator, in particular to a mechanical energy-consuming elevator buffer, which belongs to the technical field of elevator equipment. Background technique [0002] Elevator buffers mainly have two structural forms: energy storage buffer and energy consumption buffer. The energy storage buffer refers to the spring buffer, and the main component is a coil spring made of round or square steel wire. The energy-storage buffer can only be used for elevators whose rated speed does not exceed 1m / s, while the energy-consuming buffer is suitable for elevators with any rated speed and has a wide range of applications. [0003] At present, energy-consuming buffers are mainly hydraulic buffers. However, the hydraulic buffer has the following disadvantages: 1. The production and assembly accuracy is high, and the angle between the axis of the piston rod and the direction of motion c...

AI Technical Summary

Problems solved by technology

However, the hydraulic buffer has the following disadvantages: 1. The production and assembly accuracy is high, and the angle between the axis of the piston rod and the direction of motion cannot be greater than 1°; 2. The hydraulic oil is affected by the ambient temperature. Poor performance; 3. The workload of maintenance is heavy, and the hydraulic oil and seals are easily damaged and need to be replaced regularly. When more than 2 hydraulic buffers work at the same time, it should also be considered that the pressure oil chambers collude with each other to balance the oil pressure; 4 , Large size, strong disassembly strength

At present, there is no better way to solve these shortcomings, and this also leads to the relatively expensive price of hydraulic shock absorbers.
