Problems solved by technology

[0002] In the construction of transmission lines, the ropes connected to the load-bearing structure are pulled by driving mechanisms such as winches and hoists to lift and move objects. It is called a pole for short. Structural forms such as word holding pole, rocker arm holding pole, combined holding pole, etc. At present, the static load test of the holding pole adopts the traditional stay wire displacement measuring instrument, which needs to manually measure the deformation value of the holding pole under the force state of the holding pole. , the surveyor needs to be close to the pole, and the pole is under force at this time, so there is a big potential safety hazard

Embodiment Construction

[0022] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, a device for the static load test of the pole includes a static load testing machine 1, a support frame 2 supporting the pole 10, and an acquisition assembly 3 for collecting the deformation of the pole 10. The collection assembly 3 includes at least three groups, a group of collection assemblies 3 are arranged at both ends of the tested holding pole 10, at least one collection assembly 3 is arranged in the middle of the tested holding pole 10, and between adjacent two groups of collection assemblies 3 The spacing of the poles is equal, and multiple positions can be collected on the pole 10, and the deformation curve of the entire pole 10 can be described through multiple bending deformation values, and the maximum deformation can be obtained, so as to judge whether the static load test of the pole 10 is good. Bad, the accuracy of the test is improved, the static load testing machine 1 is prov...

Abstract

The invention relates to a device for the static load test of a holding pole. The device comprises a static load testing machine, a supporting frame and an acquisition assembly; the static load testing machine is provided with a fixing frame and a pull rope; the acquisition assembly comprises a support and a linear displacement sensor; the support is provided with a main control chip; the main control chip is connected with a conversion chip and a display terminal; the supporting frame comprises a base and a vertical rod; an elastic cushion is arranged on the base; and a hoisting structure is arranged on the vertical rod According to the device, the holding pole is automatically lifted through the hoisting structure arranged on the supporting frame; a distance sensor obtains the height information of the holding pole in real time; when the holding pole is lifted to a set height, the distance sensor triggers a horizontal electric push rod to act, at the moment, due to the fact that the holding pole is in the lifting state, the base can be pushed to the bottom end of the holding pole, so that the holding pole can be accurately arranged on the elastic cushion, and therefore, an operator does not need to lift the holding pole manually during the test, the working intensity of the operator is reduced, and the number of operators is reduced.

Description

technical field [0001] The invention relates to a device for static load test of a pole. Background technique [0002] In the construction of transmission lines, the ropes connected to the load-bearing structure are pulled by driving mechanisms such as winches and hoists to lift and move objects. It is called a pole for short. Structural forms such as word holding pole, rocker arm holding pole, combined holding pole, etc. At present, the static load test of the holding pole adopts the traditional stay wire displacement measuring instrument, which needs to manually measure the deformation value of the holding pole under the force state of the holding pole. , the surveyor needs to be close to the holding pole, and at this time the holding pole is in a stressed state, so there is a great potential safety hazard. Contents of the invention [0003] The object to be achieved by the present invention is to provide a device for the static load test of the pole, which can realize ...
