Abstract

The invention relates to a roller backstop. The roller backstop comprises a pawl disc and a ratchet disc. The pawl disc comprises a flange, pawls and elastic steel wires. The ratchet disc comprises a backstopping wheel and a backstopping wheel fixing disc. The roller backstop is characterized in that a key groove is opened at a central hole of the flange; the pawls surround the flange circumferentially, one end of each pawl is connected to a position of the front of the flange, which is close to the circumferential edge, a 90-degree tooth opening is formed in the other end of each pawl, and a small hole is formed in one side of each 90-degree tooth opening; the elastic steel wires are arranged at the positions in the front of the flange between the pawls, which are close to the circumferential edge, one end of each elastic steel wire is connected with each small hole in each pawl tooth opening end, and the other end is fixed at the edge of the flange; 90-degree backstopping openings are formed in the edge of the backstopping wheel, and the backstopping wheel and the backstopping wheel fixing disc are welded and fixed in a face-to-face center symmetrical mode. The roller backstop is simple and light in structure and in no need of lubrication or sealing.

Description

technical field

[0001] The invention relates to a drum backstop. technical background

[0002] In order to ensure the life safety of equipment and people in case of shutdown or sudden power failure, it is more and more common to install backstop devices on operating parts, and there are more and more types. The common ones are belt backstop, roller Type backstops, wedge-type backstop bearings, ratchet pawl backstop devices with tension and compression springs, etc., have indeed played their due role in production for a long period of time. The disadvantage is that these backstops The facilities have the disadvantages of fast wear, complex manufacturing structure, high production cost, bulky appearance, and require the backstop to be lubricated and sealed to varying degrees.

[0003] Therefore, invent a kind of simple in structure, light and handy, needn't backstop lubricated, sealing backstop seems to be increasingly needed. Contents of the invention
