Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] The fall arrester of the present invention is used to prevent the truss from falling. figure 2 As shown, the truss includes a fixedly connected frame body (not shown) and a limit truss 7; the limit truss 7 includes two vertically arranged straight bars 71 and a plurality of horizontal bars 72 arranged in parallel between the two straight bars. The cross bar 72 is a round bar with a preferred radius of 20mm. Such as figure 1 , Figure 4 As shown, the fall arrester of the present invention includes a fixed frame 1 , a limit block 6 , a V-shaped shrapnel 5 , a star wheel 2 and a hook 3 . There are two limiting blocks 6, which are respectively fixed on the left and right sides of the upper end of the fixed frame 1. A groove is arranged in the middle of the limiting block 6 along the vertical direction, and the groove matches the straight rod of the limiting tr...

Abstract

The invention discloses an anti-falling device which is used for preventing a truss from falling, wherein the truss comprises a truss body and a limiting truss which are fixedly connected with each other; the limiting truss comprises two vertically-arranged straight rods, and a plurality of transverse rods which are parallelly arranged between the two straight rods; the anti-falling device comprises a fixing frame, limiting blocks, a star wheel and a hook; two limiting blocks are respectively fixed at the left end and the right end of the fixing frame; a groove is formed in the middle of each limiting block along the vertical direction; each groove is matched with the corresponding straight rod of the limiting truss; the star wheel and the hook are respectively fixed on the fixing frame through a rotary shaft; the star wheel is uniformly provided with a plurality of star teeth along the circumferential direction; each of the star teeth and the hook is provided with a baffle block; the baffle block on each star tooth is butted to the baffle block on the hook when the star wheel rotates. The anti-falling device disclosed by the invention has the advantages of simple structure, convenience in operation and capability of effectively preventing the truss from falling.

Description

technical field [0001] In particular, the invention relates to a device for preventing a truss from falling. Background technique [0002] The trusses used in building construction are mostly driven by electric hoists. During operation, the truss suddenly falls due to the broken chain of the electric hoist or other reasons, which is very dangerous. Contents of the invention [0003] The object of the present invention is to provide a device that can effectively prevent the truss from falling in order to solve the defects in the prior art. [0004] In order to achieve the above object, the present invention provides a fall arrester, which is used to prevent the truss from falling; the truss includes a frame body and a limit truss fixedly connected; A plurality of horizontal bars arranged in parallel between them; the anti-dropping device of the present invention includes a fixed frame, a limit block, a star wheel and a hook; there are two limit blocks, which are respectiv...
