Description

Limit structure of elevator buffer Technical Field The utility model relates to the technical field of elevator safety equipment, in particular to a limiting structure of an elevator buffer. Background The elevator buffer is an important guarantee device for elevator safety operation, and can absorb the kinetic energy of the elevator when the elevator falls and other accidents occur, so that the impact force of the elevator is slowed down, and the life safety of personnel in the elevator and the elevator equipment are protected. The limiting structure plays a key role in stable installation and normal operation of the buffer, and can ensure that the buffer keeps a correct position in the working process, so that deviation or shaking is prevented from occurring, and the buffering effect is influenced. At present, the existing elevator buffer limiting structure has a plurality of problems. The part of the limiting structure adopts a simple fixing mode, such as bolt fixing, under the vibration effect generated by long-term operation of the elevator, the bolt is easy to loosen, so that the position of the buffer is deviated, and the reliability of the buffer is reduced; still some limit structure installation are dismantled inconveniently, need consume a large amount of time and manpower when maintaining and overhauling the buffer. Therefore, the elevator buffer limiting structure with stable structure and convenient installation is designed to have important practical significance. Disclosure of utility model The utility model aims to overcome the technical defects, provide a limit structure of an elevator buffer, solve the problems of poor stability, inconvenient installation and disassembly and the like of the conventional limit structure of the elevator buffer, and improve the working reliability and the maintenance convenience of the elevator buffer. In order to solve the problems, the technical scheme of the utility model is that the limit structure of the elevator buffer comprises the buffer, wherein an annular limit plate is arranged on the outer side of the buffer, one side of the annular limit plate is connected with a mounting block, corresponding slotted holes are formed in the mounting block and the annular limit plate, and a limit mechanism is arranged in each slotted hole. Further, stop gear includes the toper fixed block, the inside screw thread slotted hole that is equipped with of toper fixed block, toper fixed block bottom is fixed connection all around respectively and is equipped with spacing ball groove, four spacing ball groove one side equal fixed connection is equipped with the stopper, four the stopper upside is connected respectively and is equipped with the ball, the inside inserted bar that is equipped with of toper fixed block. Further, inserted bar bottom fixed connection is equipped with the screw thread post, screw thread post bottom fixed connection is equipped with the spring, spring bottom fixed connection is equipped with the toper piece, the toper piece is located four ball central authorities, four spacing ball groove diameter is greater than four the diameter of ball. Further, the end part of the inserted link is fixedly connected with a screwing head. Compared with the prior art, the utility model has the advantages that: 1. The buffer is initially limited through the annular limiting plate, and the conical fixing blocks, the inserting rods, the springs and other parts in the limiting mechanism are matched with each other, so that the buffer can be effectively prevented from shifting or shaking in the operation process of the elevator, and the working stability and reliability of the buffer are greatly improved. 2. The operating personnel can easily realize the up-and-down movement of the inserted link by screwing the screwing head, and then the installation and the disassembly of the limiting structure are completed, compared with the traditional bolt fixing mode, the efficiency of installation and maintenance is greatly improved, and the time and the labor cost are saved.
