As apparent from the above description, the reinforcing plate 4 can improve the structural strength of the movable plate 3.

Referring to fig. 1, further, the reinforcing plate 4 abuts against the first hook 22.

As can be seen from the above description, the reinforcing plate 4 abuts against the first hook 22 to prevent the first and second hooks from being excessively closed.

The utility model relates to a vehicle overhead guard impact test's device uses scene: when the impact test needs to be carried out on the overhead guard of the high-lift locomotive industrial vehicle, the first hook claw 22 and the second hook claw 32 are closed to lift the test load 5 and are positioned right above the vehicle 7 to be tested. Because the preload piece 1 provides the pretightening force, the first hook claw 22 and the second hook claw 32 are prevented from opening when the operation is not performed by people, so that the safety is guaranteed. Then, an operator stands at a remote place to pull the pull rope 6 connected with the movable plate 3 to open the first hook claw 22 and the second hook claw 32, so that the test load 5 freely falls to impact the overhead guard of the vehicle 7 to be tested.

Example one

A device for impact test of a vehicle overhead guard is shown in figures 1 to 5 and comprises a preload part 1, a fixed plate 2 and a movable plate 3 which are connected by a pin shaft; a hanging ring 21 is arranged at one end of the fixing plate 2, and a first hook claw 22 is arranged at one end of the fixing plate 2 far away from the hanging ring 21; the one end of fly leaf 3 is provided with through-hole 31, the one end that the through-hole 31 was kept away from to fly leaf 3 is provided with the second that colludes claw 32 with first colluding claw 22 looks adaptation, pretension piece 1 is connected between fixed plate 2 and fly leaf 3.

Referring to fig. 1 to 4, the preload member 1 includes a first pulling plate 11, a second pulling plate 12 and a spring 13; the first pulling plate 11 is arranged at one end of the fixed plate 2 far away from the hanging ring 21, the second pulling plate 12 is arranged at one end of the movable plate 3 near the through hole 31, and the spring 13 is connected between the first pulling plate 11 and the second pulling plate 12. First arm-tie 11 includes mounting panel 111 and extension board 112, the one end setting of mounting panel 111 is kept away from the one end of link 21 at fixed plate 2, extension board 112 sets up and is kept away from fixed plate 2 at mounting panel 111 and serve, and extension board 112 extends towards movable plate 3 direction, extension board 112 coupling spring 13.

Referring to fig. 1 and 4, the second hook 32 is provided with a reinforcing plate 4. The reinforcing plate 4 abuts against the first hook 22.

The working principle is as follows: in the process of impact test, one end of a pull rope 6 penetrates through the through hole 31 and is bound on the movable plate 3, then the first hook claw 22 and the second hook claw 32 are matched with each other to clamp the test load 5, and then the device and the test load 5 are hung above the vehicle 7 to be tested by utilizing the hanging ring 21 of the fixed plate 2, and the first hook claw 22 and the second hook claw 32 cannot be opened when the preload piece 1 is not manually operated due to the fact that the elastic force of the spring 13 of the preload piece 1 acts on the corresponding fixed plate 2 and the corresponding movable plate 3 through the first pull plate 11 and the second pull plate 12. Meanwhile, in order to improve the pre-tightening effect of the spring 13, the first pulling plate 11 is divided into a mounting plate 111 connected to the fixed plate 2 and an extending plate 112 extending toward the movable plate 3, and the spring 13 is connected to the extending plate 112, so that the spring 13 can be located on the same plane as the movable plate 3. Finally, an operator only needs to hold the other end of the pull rope 6 by hand and stand at a distance to pull the pull rope 6, and because the force arm at the pull rope side is larger than that at the test load side, the operator pulls the pull rope 6 to easily open the first hook claw 22 and the second hook claw 32, so that the test load 5 freely falls to impact the overhead guard of the vehicle 7 to be tested.

The above mentioned is only the embodiment of the present invention, and not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
