Description

Technical Field

[0001] This utility model relates to the field of insulating rod testing technology, and in particular to a movable insulating operating rod bending resistance test bracket. Background Technology

[0002] With the rapid development of the power industry, the application scenarios of various electrical safety tools and equipment are becoming increasingly diverse. Insulated operating rods are mainly used for safe electrical maintenance and construction operations. Their insulation performance protects workers from the risk of electric shock, and their bending resistance must also meet standard requirements to ensure worker safety. Therefore, preventative testing of insulated operating rods is particularly important. According to DL / T976-2017 Preventative Testing Procedures for Live Working Tools, Devices and Equipment, the distance between the two ends of the support varies when conducting bending tests on insulated operating rods with different pipe or rod diameters.

[0003] The existing measurement method usually uses a steel ruler or tape measure to measure the distance between the two ends of the support. This method is not accurate enough and is also quite troublesome.

[0004] Therefore, this application provides a movable insulating operating rod bending resistance test bracket to overcome the defects of the prior art. Utility Model Content

[0005] The purpose of this invention is to solve the problems that the measurement results obtained by existing measurement methods are not accurate enough and the measurement is also relatively troublesome.

[0006] This utility model provides a movable insulating operating rod bending resistance test bracket, characterized in that: it includes two opposing support rods, each support rod has a sliding component fixed at its top and a walking component rotatably connected at its bottom, an insulating rod is placed on the top of the sliding component, a laser rangefinder is fixed on one of the support rods and a laser receiving plate is fixed on the other support rod, the laser rangefinder and the laser receiving plate are arranged inside the two support rods, and the laser rangefinder and the laser receiving plate are arranged at the same height.

[0007] As a preferred technical solution, the sliding assembly includes a housing, the bottom wall of which is fixedly connected to the top wall of the support rod, a roller shaft is hinged in the housing, and a pulley 1 and a pulley 2 are fixed on the roller shaft and disposed opposite to each other, and the insulating rod is placed between the pulley 1 and the pulley 2.

[0008] As a preferred technical solution, the walking assembly includes a housing second, the top wall of the housing second being fixedly connected to the bottom wall of the support rod, and rollers being hinged in the housing second.

[0009] The beneficial effects of the movable insulating operating rod bending resistance test bracket provided by this utility model are:

[0010] This invention, by setting up a laser rangefinder and a laser receiving plate, can precisely adjust the distance between two support rods so that the distance between the two support rods meets the test requirements. Compared with measuring tools such as steel tape measures, it greatly improves the accuracy and efficiency of determining the distance.

[0011] By setting up sliding and walking components, the distance between the two support rods can be easily adjusted, saving time and effort. Attached Figure Description
