In recent years, along with the continuous occurrence of elevator accidents, people pay more attention to safety protection devices of elevators. Especially high-rise elevator, when the elevator car moves to higher floor, if the steel cable that pulls the elevator car breaks, the protector that the elevator car falls in-process generally is safety tongs, but has the condition of safety tongs malfunctioning to take place, then the elevator car will fall to elevator well pit with higher speed always, will lead to falling the ladder and cause serious accident, cause great casualties, have brought very big misery to people, and current elevator safety protection means is few.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an elevator portal frame structure, its is rational in infrastructure, through setting up buffer protection device, can reach the unexpected fall-behind buffer protection purpose of elevator.
In order to achieve the purpose, the technical scheme of the utility model is to design an elevator portal frame structure, which comprises two vertical beams arranged in parallel, and an upper beam assembly and a lower beam assembly connected between the two vertical beams; the upper end and the lower end of the vertical beam are respectively connected with guide shoes matched with an elevator guide rail, the lower beam assembly comprises a bracket and a buffer protection device, the buffer protection device comprises a first pressing plate, a second pressing plate and an impact-resistant plate, the first pressing plate is fixed at the bottom of the bracket, a pressing block is arranged at the center of the bottom of the first pressing plate, the second pressing plate is arranged below the first pressing plate, a first buffer spring is connected between the second pressing plate and the pressing block, four connecting rods which are arranged in a rectangular shape are arranged at the top of the second pressing plate, the upper end of each connecting rod penetrates through the first pressing plate and is provided with a limiting block positioned on the outer side of the bracket, and four guide holes for the four connecting rods to penetrate through are formed in the first pressing plate in a one-to; the impact-resistant plate is arranged below the second pressing plate, and four second buffer springs which are arranged in a rectangular shape are connected between the impact-resistant plate and the second pressing plate.
Preferably, two elastic pieces are connected between the second pressing plate and the impact-resistant plate.
Preferably, the elastic parts are of C-shaped structures, and the openings of the two elastic parts are arranged oppositely.
Preferably, a third buffer spring sleeved on the connecting rod is connected between the first pressure plate and the second pressure plate.
Preferably, the impact-resistant plate is covered with a rubber sleeve.
The utility model has the advantages and the beneficial effects that: the elevator portal frame structure is reasonable in structure, and the buffer protection purpose after the elevator accidental falling can be achieved by arranging the buffer protection device.
When the elevator car accidentally falls, the impact-resistant plate contacts the bottom of the elevator shaft, then the portal frame drives the first pressing plate and the second pressing plate to move downwards, and the second buffering spring is compressed when the second pressing plate moves downwards, and the second pressing plate also deforms the extrusion elastic piece; when the first pressing plate moves downwards, the first buffer spring and the third buffer spring are compressed, so that impact force on personnel in the elevator car is absorbed by the first buffer spring, the second buffer spring, the third buffer spring and the elastic piece together, and the purpose of buffer protection is achieved. In addition, the rubber sleeve is coated outside the impact-resistant plate, so that the impact-resistant plate can be effectively protected, and the phenomenon that the impact-resistant plate is broken due to overlarge stress is avoided.
