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...
