Construction hoisting and tightening assisting device with anti-loosening function

Abstract

A construction hoisting and tightening assisting device with an anti-loosening function comprises a mounting plate and a telescopic rod, wherein supporting plates are symmetrically arranged on the mounting plate; a pulley is arranged between the supporting plates; a first anti-loosening wheel is arranged on one side of the pulley; one side of each of the supporting plates is provided with a corresponding fixed plate; the fixed plates are rotationally connected with movable plates; a tightening wheel is arranged between the movable plates; and a second anti-loosening wheel is arranged on one side of the tightening wheel. The construction hoisting and tightening assisting device with the anti-loosening function is provided with the first anti-loosening wheel and the second anti-loosening wheel which can be used for limiting the position of a steel wire rope, thereby preventing the steel wire rope from being loosened from the pulley and the tightening wheel, and greatly improving the use safety of the steel wire rope. In addition, the construction hoisting and tightening assisting device is provided with the telescopic rod and the movable plates which have the functions of disassembly and assembly, thereby facilitating the observation of wear of the two ends of the telescopic rod in the later period, and facilitating the replacement.

Description

technical field [0001] The invention relates to the technical field of building hoisting equipment, and more particularly, to an auxiliary tensioning device for building hoisting with an anti-dropping function. Background technique [0002] At present, when building a house, various mechanical tools need to be used, including a hoist and an auxiliary tensioning device. However, most of the pulleys provided in the existing auxiliary tensioning device have no anti-fall function. During the use of the wire rope , it may cause the wire rope to loosen from the pulley, causing serious wear and tear of the wire rope, shortening the service life of the wire rope, and the loosening of the wire rope will also cause certain dangers. The end position is not easy to disassemble. Because the two ends of the electric telescopic rod are connected by rotation, it will cause serious wear and tear after long-term use. It needs to be replaced, which may bring some inconvenience to the replaceme...

Problems solved by technology

[0002] At present, when building a house, it is necessary to use various mechanical tools, including hoists and auxiliary tensioning devices, but most of the pulleys provided by the existing auxiliary tensioning devices do not have the function of preventing detachment. , may cause the steel wire rope to loosen out of the pulley, causing severe wear of the steel wire rope, shortening the service life of the steel wire rope, and the loosening of the steel wire rope will also cause certain dangers, and the electric telescopic rod set by the existing auxiliary tensioning device will be two The end position is not easy to disassemble. Because the two ends of the electric telescopic rod are connected by rotation, it will cause serious wear and tear after long-term use and need to be replaced, which may bring some inconvenience to the replacement. Building lifting auxiliary tensioning device to solve the above problems
