Problems solved by technology
[0003] However, there are a series of problems behind the rapid development of the industry: According to the requirements of the standard GB4623-2014 circular concrete poles, before leaving the factory, concrete poles should be subjected to random inspection of mechanical properties according to the production batch to ensure their production quality, but the existing poles The detection equipment is backward, which not only reduces the detection accuracy and efficiency, but more importantly, brings safety hazards to the detection personnel at work
This work is highly dangerous. Once the rope on the force application side of the pole slips or the pole breaks due to insufficient mechanical properties, the workers on the tension side will be very dangerous

Embodiment 1
[0017] The device of the present invention is composed of five main parts: a track 2, a trolley 3, a controller 4, a crack recognition system 6, and a self-developed special concrete crack measuring instrument 7.
[0018] like figure 1 , 2 As shown, the track 2 is soft and can be folded. When in use, it is laid horizontally directly above the pole as a guide for the entire system; the trolley 3 is composed of a body body and spring leaf support legs. The identification system 6 uses the 3D laser profile measuring instrument branded as KEYENCE, and the special concrete crack measuring instrument 7 adopts the function of the CW50 crack width measuring instrument produced by Yutong Times Company, and can carry the above components along the electric track 2 The rod moves axially, and its moving speed is fixed. The start and stop are controlled by the controller 4. The spring support legs help the trolley 3 to hold the body of the pole with different diameters. To the starting p...

The invention relates to a device for detecting the cracks of an electric pole, which is characterized in that: a track (2) mounted on an electric pole to be detected is comprised; a trolley (3) capable of moving along the track (2) is mounted on the track (2); a crank arm (5) is mounted on one side of the trolley (3); a crack identification system (6) and a dedicated concrete crack measuring instrument (7) are respectively mounted on the crank arm (5); the crack identification system (6) and the dedicated concrete crack measuring instrument (7) are respectively connected to the controller (4)mounted on the trolley (3). The invention provides a crack automatic detection device. The device can move along the axial direction at the tension side of the electric pole according to program settings or the remote control of a worker through a remote control switch, and actively discover the cracks and measure the width of the cracks, so that the labor intensity and the dangerousness of the workers are greatly reduced, and the detection accuracy and the working efficiency are remarkably improved.
Description
technical field [0001] The invention relates to an electric pole crack detection device. Background technique [0002] Concrete poles are one of the important products involved in infrastructure projects. In the power industry, it is mainly used in the line erection of rural power grid reconstruction. In addition, cement poles are also widely used in other industries such as telecommunications line erection. According to the report of the circular concrete pole industry association, since 2015, the output of circular concrete poles in my country has increased year by year, and by 2017 it had exceeded 18 million. [0003] However, there are a series of problems behind the rapid development of the industry: According to the requirements of the standard GB4623-2014 circular concrete poles, before leaving the factory, concrete poles should be subjected to random inspection of mechanical properties according to the production batch to ensure their production quality, but the exi...
