[0035] The utility model proposes a relay protection test bench, comprising: a workbench 1; the workbench 1 is a rectangular plate-shaped structure, four supporting legs 101 are welded to the bottom end surface of the workbench 1, and one end below the four supporting legs 101 is in contact with the ground; a tester 2 for realizing relay protection test is fixed on the workbench 1; a lifting assembly 3 is welded on the supporting leg 101; a control box and buttons for realizing control of an electric cylinder 302 are installed on the top end surface of the workbench 1.

[0036] Among them, the lifting assembly 3 is composed of a connecting rod 301, an electric cylinder 302 and a support block 303. There are two connecting rods 301. One connecting rod 301 is welded between the two front support legs 101, and another connecting rod 301 is welded between the two rear support legs 101. Both connecting rods 301 are rectangular rod-shaped structures, and both connecting rods 301 are hollow materials.

[0037] Among them, two electric cylinders 302 are symmetrically welded to the bottom end surface of each connecting rod 301, and a control box and buttons for controlling the electric cylinders 302 are installed on the top surface of the workbench 1. The lower ends of the two front electric cylinders 302 are welded to a support block 303, and the two rear electric cylinders 302 are welded to another support block 303. When the height of the workbench 1 needs to be adjusted, the four electric cylinders 302 can be controlled to extend at the same time.

[0038] Among them, the support block 303 is a convex structure, and the electric cylinder 302 and the support block 303 together constitute an auxiliary structure for the movement of the workbench 1. When the workbench 1 needs to be moved, the forklift arm is inserted between the support block 303 and the connecting rod 301, and the four electric cylinders 302 are controlled to retract. The forklift arm can be clamped by the support block 303 and the connecting rod 301, and the device can be prevented from being separated from the forklift arm during the movement.
