Description

Technical Field

[0001] The utility model relates to the technical field of wear tests of electric power fittings, and particularly relates to a wear test device for electric power fittings. Background Art

[0002] An overhead line mainly refers to an overhead open wire, which is erected above the ground. It is a transmission line that uses insulators to fix transmission conductors on poles standing upright on the ground to transmit electric energy. Erection and maintenance are relatively convenient, and the cost is relatively low. The main components of an overhead line include: conductors and lightning conductors, poles, insulators, electric power fittings, pole foundations, guy wires, and grounding devices, etc.

[0003] In the prior art, after the electric power fittings are installed and during the actual operation of the line, they not only have to bear the gravity of the conductors, but also, in a strong wind environment, have to bear the additional force superimposed due to the swaying of the conductors, causing the electric power fittings to slide and generate frictional force. After the electric power fittings are worn, it will affect the safety of the line. The U-shaped hanging ring is one of the electric power fittings. In production, a wear test needs to be carried out on the U-shaped hanging ring to determine the service life of the U-shaped hanging ring. Among them, for the wear test device of the U-shaped hanging ring, such as the wear testing machine mentioned in the patent application document with the application number CN201310367302.8, it uses the method of connecting a motor to a connecting rod to drive the U-shaped hanging ring to swing reciprocally to complete the simulated swing of the U-shaped hanging ring, and then complete the wear test of a pair of U-shaped hanging rings.

[0004] However, there are still certain problems when using the above operation method: when the wear tests of multiple hanging rings in the same batch of U-shaped hanging rings are required, since only a pair of U-shaped hanging rings can be tested on each wear testing machine, multiple tests are required for the wear tests of multiple U-shaped hanging rings. However, each test requires tens of thousands of times of wear, and the single test process is relatively long, resulting in an overly long overall time. If you want to reduce the overall test time, only multiple wear testing machines can be used for synchronous testing, and at this time, the equipment purchase cost required is relatively high. Summary of the Utility Model

[0005] The utility model aims at the problems in the prior art and provides a wear test device for electric power fittings that can test multiple groups of U-shaped hanging rings, solves the problem in the prior art that multiple tests are required for the wear tests of multiple U-shaped hanging rings, resulting in an overly long overall time, and at the same time solves the problem of the excessively high equipment cost caused by reducing the test time.

[0006] The technical solution adopted by the utility model is as follows:

[0007] An electric hardware wear test device includes a driving mechanism and a testing mechanism, the testing mechanism is connected to the driving mechanism, the driving mechanism includes a driving motor and at least two guides, the testing mechanism is provided with at least one, the guide includes a guide plate and a connecting shaft, the guide plate is a circular plate, the connecting shaft is fixedly connected to the guide plate and is coaxial, the connecting shaft can be connected to the output shaft of the driving motor or the guide plate of an adjacent guide, both sides of the guide plate are provided with guide grooves, the adjacent guide grooves on adjacent guides are projected colinearly in the horizontal direction, the testing mechanism includes a connecting rod, one end of the connecting rod is slidably sleeved in the adjacent guide grooves on the adjacent guides. By setting up the driving mechanism, when there are multiple groups of test requirements, guides can be added to increase the position where the connecting rod can be placed, thereby achieving the effect of adding test mechanisms to complete the increase of test groups, without adding wear testing machines, reducing the cost of multiple groups of tests, and a single operation can make multiple groups of tests be carried out together, shortening the total test time.

[0008] Preferably, the guide grooves are connected end to end in the circumferential direction of the guide plate. By providing the guide grooves connected end to end in the circumferential direction of the guide plate, the swing of the test mechanism can be completed by controlling the drive motor to move in one direction, avoiding the need to control the motor to move back and forth and thus reduce the test speed.

[0009] Preferably, the guide groove is an elliptical groove.

[0010] Preferably, the long axes of the two guide grooves on the same guide plate are perpendicular to each other. By setting the positions of the two guide grooves on the same guide plate, when multiple test mechanisms move together, the swing directions of two adjacent test mechanisms are in opposite states in real time, and the swing inertia of the two adjacent test mechanisms can be offset, avoiding the risk of large shaking of the equipment.

[0011] Preferably, the guide member is provided with countersunk holes and connecting holes, each guide member is provided with two countersunk holes and two connecting holes, the countersunk holes and connecting holes are alternately and evenly arranged in the circumferential direction of the guide member, and the countersunk holes and connecting holes are connected by bolts between adjacent guide members. By providing the countersunk holes and connecting holes, a bolt connection method can be adopted when increasing or decreasing the number of guide members, which can improve the efficiency of installing and removing the guide plate while ensuring a stable connection.

[0012] Preferably, the test mechanism also includes a rocker arm hinged in the middle part to the other end of the connecting rod, the lower end of the rocker arm is connected to an arc guide rail, the lower end of the rocker arm is sleeved in the arc guide rail and can move back and forth along the arc guide rail, the upper end of the rocker arm is used to connect to one of the U-shaped hanging rings of the U-shaped hanging ring group, the test mechanism also includes a load unit and a connecting chain, and the load unit can be connected to another U-shaped hanging ring of the U-shaped hanging ring group through the connecting chain.

[0013] Preferably, the test mechanism also includes a fixed guide wheel and a connecting block, the connecting block is used to install another U-shaped hanging ring of the U-shaped hanging ring group, one end of the connecting chain is connected to the connecting block, and the connecting chain bypasses the guide wheel and is connected to the load unit.

[0014] Preferably, the load unit includes a mounting plate and a load block, the mounting plate is connected to the connecting chain, and a plurality of load blocks are provided and can be detachably provided on the mounting plate. By providing a plurality of detachable load blocks, the load simulation adjustment of the U-shaped hanging ring can be performed under different models of power fittings and different environments.

[0015] It can be seen from the above technical solutions that the advantages of the utility model are: by setting the driving mechanism, it is possible to add guides when there are multiple test requirements, thereby increasing the position where the connecting rod can be placed, thereby achieving the effect of adding test mechanisms to complete the increase of test groups, without adding wear testers, reducing the cost of multiple test groups, and a single operation can make multiple test groups be carried out together, shortening the total test time. By setting the guide grooves connected end to end in the circumferential direction of the guide plate, the swing of the test mechanism can be completed by controlling the unidirectional movement of the drive motor, avoiding the phenomenon of needing to control the reciprocating motion of the motor to reduce the test speed. By setting the positions of the two guide grooves on the same guide plate, when multiple test mechanisms are moving together, the swing directions of the two adjacent test mechanisms are in opposite states in real time, and the swing inertia of the two adjacent test mechanisms can be offset, avoiding the risk of large shaking of the equipment. By setting the countersunk holes and connecting holes, the bolt connection method can be used when increasing or decreasing the number of guide members, and the efficiency of installing and removing the guide plate can be improved when ensuring a stable connection. By setting a number of detachable load blocks, the load simulation adjustment of the U-shaped hanging ring can be carried out in different models of power hardware and different environments.
