Abstract

The invention provides a tension alarm device, which can solve the problems in the prior art that the cables of construction machinery are easily broken, resulting in increased costs and potential safety hazards. By installing the tension alarm device on the construction machinery, it can effectively prevent the cable from being damaged, reduce the cable damage rate and the maintenance rate of the machine, and prolong the service life of the cable. The technical solution is as follows: a pull alarm device, including a shell part, a cover plate and a base that are sealed and connected; a pull rod part, including a pull rod that can move up and down according to external pulling force; , the lever accepts the pulling force of the pull rod to drive the compression rod and the rotating support to swing; the alarm part includes an electrically connected toggle switch, an alarm circuit module and a loudspeaker, and the toggle switch accepts the movement of the rotating support The state is changed by power; the fixed part includes a drag hook and at least one lengthening screw, and the lengthening screw runs through the base.

Description

technical field [0001] The invention relates to the field of construction, in particular to a tension alarm device for preventing cables of construction machinery from being broken. Background technique [0002] Construction machinery such as construction hoists and hanging baskets for high-altitude operations use clamps or binding methods to fix the cable ends on the outside of the working platform, and then rise and fall together with the working platform. Due to objective reasons, it is difficult for the operator to observe the situation below the working platform during the upward movement of the machine, and obstacles protruding from the wall often hang and break the cables. Construction machinery is mostly used in open-air places with complex working environments. It is difficult to repair the cables after being hung up many times. The insulation performance and minimum breaking force of the cables are greatly reduced. It is easy to cause leakage and phase failure due ...
