Problems solved by technology

[0004] However, since this operation is completely performed manually, the lower knife edge of the impact block is not perpendicular to the axis of the middle joint of the cable under test at the moment of impact, which will cause the impact point to deviate from the preset impact position; As a result, the test personnel's feet were accidentally injured by the impact block

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] refer to figure 1 , is a mechanical impact test device 1 disclosed in the present invention, including a body 10, an impact mechanism 20, and a placement mechanism 30; the impact mechanism 20 is slidably connected to the body 10, and the impact mechanism 20 can slide along the first direction 80 of the body 10 Through the slidable connection between the impact mechanism 20 and the body 10, compared with the simple manual impact test, on the one hand, the position deviation of the impact mechanism 20 during the movement along the first direction 80 is avoided, and the accuracy of the position of the impact mechanism 20 is improved. On the other hand, the deviation between the height of the impact mechanism 20 moving along the first direction 80 and the specified height is avoided, the rigor of the mechanical impact test is improved, and the manpower is ...

Abstract

The invention relates to a mechanical impact test device, which comprises a body, an impact mechanism and a placement mechanism. The impact mechanism is slidably connected with the body, the impact mechanism can slide in the first direction of the body, the placing mechanism is arranged on the body, the placing mechanism and the impact mechanism are correspondingly arranged, the placing mechanism can rotate relative to the body, and the placing mechanism is used for placing a cable intermediate joint; the impact mechanism comprises an adsorption assembly and an impact hammer, one end of the adsorption assembly is slidably connected with the body, and the impact hammer is in adsorption connection with the end, away from the body, of the adsorption assembly and used for impacting the cable intermediate connector. Through the arrangement, compared with a simple manual impact test, the accuracy and the preciseness of a mechanical impact test are improved; the feet of a tester are prevented from being injured, and the safety of a mechanical impact test is improved; meanwhile, manpower is reduced, and the efficiency and quality of the mechanical impact test are improved.

Description

technical field [0001] The invention relates to the technical field of impact test devices, in particular to a mechanical impact test device. Background technique [0002] The cable intermediate joint is an important part of the power cable line, and it is the part with the highest failure rate in the cable line. During the construction, installation and subsequent operation of the cable line, the intermediate joint of the cable may be subjected to external force. If the external force exceeds the bearing capacity of the joint, the internal shielding layer, insulation, conductor, stress cone or insulating tube of the joint may be damaged to a certain extent, and then the To avoid potential failures such as water ingress or breakdown of connectors. The mechanical impact test of cable intermediate joints is to assess the ability of cable joints to withstand external force impacts. It is a mandatory test item for cable intermediate joints in GB / T 28427-2012 and IEC 61442:2005....
