Description

Technical Field

[0001] The utility model belongs to the technical field of mine ore transportation and relates to a device for preventing a mine car from tipping over. Background Art

[0002] In the existing process of underground ore transportation, small mine cars can usually only withstand the impact of small-sized ores falling from the chute funnel. Since small mine cars lack a certain degree of stability, when large pieces of ore are released, the vehicle is prone to overturning and tipping, posing a safety hazard and reducing the mining efficiency. Utility Model Content

[0003] The utility model aims to provide a device for preventing a mining vehicle from tipping over in view of the problems existing in the prior art, thereby solving the problem that the vehicle is prone to tipping over during the process of sliding large pieces of ore.

[0004] To this end, the utility model adopts the following technical solutions:

[0005] A device for preventing a mine car from tipping over comprises a support frame, wherein a slide groove is provided on the top of the support frame, a mine car is provided on the side, a fixing ring is provided on the side wall of the support frame, a hook is provided on the side wall of the mine car, the fixing ring and the hook are arranged opposite to each other, and a chain is provided therebetween, and the fixing ring, the chain and the hook are connected by a connecting ring.

[0006] Furthermore, the chain is formed by a plurality of oval rings connected together;

[0007] Furthermore, a connecting hole is provided at the bottom of the hook claw, and the connecting ring passes through the connecting hole to be connected to the hook claw.

[0008] Furthermore, the cross section of the slide groove is a quadrilateral containing three right angles.

[0009] The beneficial effects of the utility model are:

[0010] When large pieces of ore slide down the ore chute into the mine car, they collide with the side wall of the mine car to generate impact force. The utility model gives the mine car a reaction force through a buffer system composed of a circular chain, an F-shaped hook claw, and a U-shaped fixed ring, so that it can withstand the impact force of large pieces of ore, increase the stability of the mine car, avoid rollover, thereby reducing safety hazards and improving ore transportation efficiency.

[0016] The technical solution of the utility model is described below in conjunction with the accompanying drawings and implementation methods.

[0017] like Figure 1 As shown, a device for preventing a mine car from tipping over comprises a support frame 2, a chute 1 is provided on the top of the support frame 2, and a mine car 6 is provided on the side. Specifically, the cross section of the chute 1 is a quadrilateral containing three right angles.

[0018] The side wall of the support frame 2 is provided with a fixing ring 3, such as Figure 2 As shown, the fixing ring 3 is U-shaped; the side wall of the mining car 6 is provided with a hook 5, as shown Figure 3 As shown, the hook 5 is F-shaped; the fixing ring 3 and the hook 5 are arranged opposite to each other, and a chain 4 is arranged between the two. Specifically, the chain 4 is formed by a plurality of elliptical ring bodies sleeved together; Figure 4 As shown, the fixing ring 3 , the chain 4 and the hook 5 are connected via a connecting ring 8 .

[0019] A connecting hole 7 is provided at the bottom of the hook 5 , and a connecting ring 8 passes through the connecting hole 7 and is connected to the hook 5 .

[0020] The use process of the utility model is as follows:

[0021] First, the mine car 6 runs to the bottom of the chute 1 via the track. Before opening the gate of the chute 1, the two sets of hooks 5 are clamped on the proximal side wall of the mine car 6. When large pieces of ore slide through the chute 1 of the ore hopper to the mine car 6 and collide with the side wall of the mine car to produce an impact, it can withstand the impact force of the large pieces of ore, increase the stability of the mine car 6, and avoid rollover, thereby reducing safety hazards and improving the efficiency of ore transportation. When the mine car 6 is full, the two sets of hooks 5 are removed and the mine car 6 continues to move forward.
