Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction and relates to a tire stone-blocking prevention device for a tunnel dump truck. Background Art

[0002] Tunnel dump trucks haul waste rock underground in mines. They frequently operate at tunnel faces and section roads, near rough storage bins, and at rough rock chutes. These locations contain waste rock from blasting, spilled in the tunnels, and dropped during loading and unloading. However, the tunnels themselves aren't cleaned constantly on-site, leading to waste rock getting stuck between the double-row tires of the trucks during transportation. This accelerates tire wear and can easily lead to blowouts. Preventing waste rock from getting stuck between the double-row tires of tunnel dump trucks and reducing tire wear caused by this jam is a challenging problem for underground dump trucks. Utility Model Content

[0003] The purpose of the utility model is to address the problems existing in the prior art and provide a device for preventing stone jamming in the tires of a tunnel dump truck, thereby solving the problem that gangue is easily jammed between the gaps between the double-row tires of the tunnel dump truck during underground transportation operations, resulting in rapid tire wear and prone to tire blowout accidents.

[0004] To this end, the present invention adopts the following technical solutions:

[0005] A stone-prevention device for the tire of a tunnel dump truck comprises a fixing plate, which is square in shape and has a number of fixing bolts symmetrically arranged near the four corners. A support rod is provided on the side wall of the fixing plate, and the two are vertically connected. One end of the support rod is connected to the fixing plate, and the other end is provided with a connecting shaft. The outer wall of the connecting shaft is provided with an anti-stone baffle and a rubber pad. One side of the anti-stone baffle is in contact with the rubber pad, and the other side is in contact with the support rod. Two positioning holes are symmetrically provided on the side wall of the connecting shaft, and positioning pins are inserted into the two positioning holes. The positioning pins are vertically connected to the connecting shaft, and their ends both pass through the side wall of the connecting shaft.

[0006] Furthermore, the support rod is concentrically connected to the connecting shaft.

[0007] Furthermore, the diameter of the support rod is larger than the diameter of the connecting shaft.

[0008] The beneficial effects of the present invention are:

[0009] The utility model can prevent stones from being stuck between the double-row tires of the tunnel dump truck, has a simple structure, is easy to use, increases the service life of the tires of the tunnel dump truck, and reduces the tire maintenance and replacement rate.

[0014] The technical solution of the present invention is described below in conjunction with the accompanying drawings and implementation methods.

[0015] like Figures 1-3 As shown, a tunnel dump truck tire stone prevention device includes a fixing plate 1, which is square and has four fixing bolts 2 symmetrically provided near the four corners; specifically, the fixing bolt group 2 uses M8*40mm 8.8 grade high-strength bolts, and its purpose is to connect the utility model to the vehicle frame through the fixing bolt group 2.

[0016] The side wall of the fixed plate 1 is provided with a support rod 3, and the two are vertically connected. One end of the support rod 3 is connected to the fixed plate 1, and the other end is provided with a connecting shaft 4. The outer wall of the connecting shaft 4 is provided with an anti-stone baffle 5 and a rubber pad 6. Specifically, the rubber pad 6 has a size of DN50 and a thickness of 2mm.

[0017] One side of the anti-stone baffle 5 is in contact with the rubber pad 6 and the other side is in contact with the support rod 3. Two positioning holes are symmetrically provided on the side wall of the connecting shaft 4. Positioning pins 7 are inserted into the two positioning holes. The positioning pins 7 are vertically connected to the connecting shaft 4, and their ends both pass through the side wall of the connecting shaft 4.

[0018] Specifically, the support rod 3 is concentrically connected to the connecting shaft 4 , and the diameter of the support rod 3 is larger than the diameter of the connecting shaft 4 .

[0019] The utility model is used in the following process:

[0020] First, weld the support rod 3 to the fixed plate 1, then weld the connecting shaft 4 concentrically with the support rod 3, put the anti-stone baffle 5 and the rubber pad 6 on the connecting shaft, and then insert the locating pin 7 into the locating hole of the connecting shaft 4. Finally, fix the fixed plate 1 to the tunnel dump truck beam with a fixing bolt group, so that the anti-stone baffle 5 is located between the middle gap of the double-row tires. The anti-stone baffle 5 swings back and forth as the vehicle runs, avoiding the gangue getting stuck in the middle of the double-row tires and causing tire damage, avoiding the risk of manual cleaning of stone jams, reducing the increased tire consumption and tire blowout probability due to stone jams, and reducing the cost of vehicle use.
