The frame is provided with a stepped hole coaxial with the pin hole and with its small diameter section close to the pin hole. The stepped hole is provided with limit block clearance grooves on both sides of its small diameter section. The stepped hole has two limit grooves on the segment surface between its large diameter section and its small diameter section. The end of the positioning pin with the limit block passes through the pin hole and extends into the stepped hole. The limit block is engaged in the limit groove. A spring is sleeved on the positioning pin, and the spring is compressed between the stop block and the bumper body.

[0007] Preferably, the front of the bumper body is provided with a countersunk hole, and the pin hole is located in the countersunk hole.

[0008] Preferably, the front of the bumper body is provided with two drag rings.

[0009] Preferably, a radar mounting bracket is provided on the back of the bumper body.

[0010] Preferably, the back of the bumper body is provided with a sensor connection flange.

[0011] The beneficial effects of this utility model are as follows: the bumper body is provided with a guide rod, the vehicle frame is provided with a guide hole, and the guide rod is inserted into the guide hole to ensure the stability of the connection between the bumper body and the vehicle frame; a quick-release mechanism for quickly installing and removing the bumper body is connected between the bumper body and the vehicle frame, which avoids the problem that the bumper cannot be replaced after damage due to the traditional welding method.

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to specific embodiments. Example

[0017] like Figs. 1-3 As shown, this utility model discloses a movable front bumper for a mining bidirectional transport vehicle, which is connected to the end of the vehicle frame 1. It includes a bumper body 2 and a guide rod 3 located on the back of the bumper body 2. The vehicle frame 1 is provided with a guide hole 4, and the guide rod 3 is inserted into the guide hole 4. A quick-release mechanism for quickly installing and removing the bumper body 2 is connected between the bumper body 2 and the vehicle frame 1.

[0018] The quick-release mechanism includes a positioning pin 5, one end of which is provided with a stop block 6, and the other end is provided with limit blocks 7 on both sides. The bumper body 2 is provided with a pin hole 8, and the pin hole 8 is provided with limit block clearance grooves 9 on both sides. The frame 1 is provided with a stepped hole 10 coaxial with the pin hole 8 and with its small diameter section close to the pin hole 8. The stepped hole 10 is provided with limit block clearance grooves 9 on both sides of its small diameter section.
