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

Embodiment Construction
[0021] The drawings show a specific embodiment of the invention. This embodiment includes a gravity trigger device 6, a sound unit 8, a light emitting unit 9, and a battery pack 7. It is characterized in that: the gravity trigger device 6 includes a dial 1, a pointer 2, a weight 4 and a contact 3, a pointer 2 and a touch Point 3 is a conductor. Pointer 2 is rotatably installed at the center of dial 1 via a rotating shaft. The lower end of pointer 2 is connected to weight 4. The upper edge of dial 1 is provided with a scale 5 indicating the allowable range of the tilt angle of pointer 2. Two contacts 3 Install the pointer 2 on the radius of the dial 1 where the maximum inclination angle is allowed at the left and right ends of the pointer 2 and ensure that the pointer 2 can touch the two contacts 3 when turning left and right. The two contacts 3 are connected in parallel with the sound unit 8, The light-emitting unit 9, the battery pack 7, and the pointer 2 are connected in seri...

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 a gravity-triggered sound and light alarm device for holding poles in power transmission and transformation construction. (2) Background technology [0002] In the construction of transmission and transformation line towers, the pole is used as a vertical lifting tool, and its verticality is an important indicator to measure whether it is safe and stable, and it is related to the safety of the personnel in the construction of the tower. [0003] The traditional method is to use manual visual inspection to monitor whether it is skewed in real time after the pole assembly is completed, or use optical instruments such as theodolite to observe its verticality regularly to ensure that the tilt is within the allowable range, if it is obvious visually If it is tilted, immediately stop the construction and check the bottom support rope, waist ring ...
