Abstract

The invention provides a tensile force alarm device, which can solve the problems of cost increment and easy occurrence of potential safety hazard caused by easy breakage of cables of construction machines existing in the prior art. The tensile force alarm device is arranged on the construction machine, effectively prevents the cables from being broken, reduces cable damage rate and mechanical maintenance rate, and prolongs the service life of the cables. The invention adopts the technical following scheme that: the tensile force alarm device comprises a shell part, a pull rod part, a deflector rod part, an alarm part and a fixing part, wherein the shell part comprises cover plates and a base which are hermetically connected; the pull rod part comprises a pull rod capable of moving up and down according to external tensile force; the deflector rod part comprises a deflector rod, a compression rod and a rotary support, and the deflector rod receives the tensile force of the pull rod to drive the compression rod and the rotary support to swing; the alarm part comprises a toggle switch, an alarm circuit module and a loudspeaker which are electrically connected, and the toggle switch receives motive power of the rotary support to change state; and the fixing part comprises a drag hook and at least one lengthened screw, and the lengthened screw passes 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 ...
