Power transmission and transformation construction derrick inclining sound and light alarm device based on gravity trigger

Abstract

The invention relates to the technical field of power transmission and transformation construction, and particularly relates to a power transmission and transformation construction derrick inclining sound and light alarm device based on gravity trigger. The device comprises a gravity trigger device, a sound emitting unit, a light emitting unit and a battery pack, wherein the gravity trigger device comprises a dial plate, a pointer, a heavy punch and contacts, the pointer and the contacts are conductors, the lower end of the pointer is connected with the heavy punch, scales expressing an inclined angle tolerance range of the pointer are formed on the upper edge of the dial plate, and the two contacts are respectively installed on the radii, on which the largest inclined angle tolerance scales of the left and right ends of the pointer are formed, of the dial plate. According to the device, the real-time continuous monitoring of the perpendicularity of a derrick in three dimensions, at multiple angles and in multiple planes can be realized by utilizing a lever principle, construction workers are reminded of taking measures by virtue of the automatic sound and light alarming when the degree of inclination exceeds a permissible error, so as to guarantee the security of workers, and the device is suitable for being widely popularized and applied.

Description

(1) Technical field [0001] The invention relates to the technical field of power transmission and transformation construction, in particular to an acousto-optic alarm device for tilting poles in power transmission and transformation construction based on gravity triggering. (2) Background technology [0002] In the tower construction of power transmission and transformation lines, the pole is used as a vertical lifting tool, and its verticality is an important indicator to measure its safety and stability, which is related to the safety of personnel in tower construction. [0003] The traditional method is to use manual visual inspection to monitor whether it is deflected in real time after the pole is assembled, or use optical instruments such as theodolite to regularly observe its verticality to ensure that the inclination is within the allowable range. If it is tilted, stop the construction immediately and check the bottom rope, waist ring and pull wire of the pole, a...

AI Technical Summary

Problems solved by technology

The disadvantage of artificial visual inspection is firstly that it is inaccurate, and the inclination angle of the pole can be judged by experience; secondly, uninterrupted continuous monitoring cannot be guaranteed; the third is that the limitation of the observation angle makes it only possible to monitor the inclination of a plane parallel to the observer and cannot observe The inclination perpendicular to the observer is very prone to misjudgment and lead to safety accidents
