Description

Technical Field

[0001] The invention belongs to anti-slip equipment for a mining dump truck, and in particular relates to a wheel cover block for a mining dump truck and a use method thereof. Background Art

[0002] Mining dump trucks are large off-road transport equipment used to transport earth and minerals in open-pit mines. They have huge deadweight and load capacity, are equipped with giant engineering tires, and operate on harsh road conditions. In order to ensure that the dump truck can stop reliably on various transport roads, or to avoid accidents such as slipping caused by failure of the parking brake system during maintenance, mining dump trucks are usually required to be equipped with wheel blocks.

[0003] Announcement No. CN204415363U discloses a support for mounting tire mask blocks for mining dump trucks. The support base for fixing the tire mask blocks is welded on the front bumper of the frame; the tire mask blocks are installed on the support base; the support gland is fixed on the support base through a split pin and the tire mask blocks are pressed by the secondary shaft. The support base is provided with adjustment limit holes at different positions. The positions of these holes are designed for the tire mask blocks of different external dimensions. The size of the holes just passes through the split pin. The support gland is also provided with a limit hole of the size just passing through the split pin. When the support gland is pressed into the support base, the support gland has different pressing depths according to the different external dimensions of the tire mask blocks. The upper limit hole of the support gland will be aligned with the adjustment limit hole at a certain position on the support base. The split pin is inserted into the aligned small hole to achieve the fixation of the rim mask blocks of different external shapes. The tire mask blocks connected by the support are connected by plug-in connection, resulting in low structural strength, and easy to slip on slippery roads, and cannot effectively prevent the wheels from moving. Summary of the invention

[0004] The purpose of the present invention is to provide a wheel cover block for a mining dump truck and a use method thereof, which can effectively stop the mining dump truck under various road conditions and prevent the occurrence of a slipping accident.

[0005] Technical solution:

[0006] The wheel cover block of a mining dump truck is a triangular column as a whole, comprising: a triangular frame, a main connecting pipe, a secondary connecting pipe and an anti-skid pipe. Multiple triangular frames are arranged in parallel, the main connecting pipe is connected to the vertices of the multiple triangular frames, the secondary connecting pipe is connected between two adjacent triangular frames, and multiple anti-skid pipes are respectively connected to the side walls of the main connecting pipe.

[0007] Furthermore, the triangular frame includes: an inclined tube, a bottom tube, a support tube and a rib plate. The inclined tube, the bottom tube and the support tube are connected end to end in sequence to form a triangular structure. The rib plate is connected to the side of the triangular frame.

[0008] Furthermore, the rib plate is connected to the inclined tube, the bottom tube and the side wall of the supporting tube.

[0009] Furthermore, the rib plate is provided with a plurality of circular holes for weight reduction.

[0010] Furthermore, the secondary connecting pipes are connected between adjacent secondary connecting pipes, main connecting pipes, between two adjacent inclined pipes, and between two adjacent bottom pipes.

[0011] Furthermore, the wheel mask is provided with three triangular frames, the three triangular frames are arranged equidistantly, three main connecting pipes are respectively connected to the three vertex positions of the three triangular frames, and three anti-skid pipes are respectively connected to the side walls of the main connecting pipes.

[0012] Furthermore, the main connecting pipe is perpendicular to the triangular frame.

[0013] Furthermore, a slope is arranged at the bottom of the anti-slip tube.

[0014] Furthermore, the inclined tube, bottom tube, support tube and rib plate are welded and connected, and the triangular frame, main connecting tube, secondary connecting tube and anti-skid tube are welded and connected.

[0015] The method of using the wheel mask of a mining dump truck includes:

[0016] When the dump truck stops, a wheel block is placed on both sides of the front and rear wheels, the bottom pipe, main connecting pipe and secondary connecting pipe of the triangular frame are in contact with the ground, and the inclined pipe, main connecting pipe and secondary connecting pipe are in contact with the wheels;

[0017] When the wheel moves, the wheel squeezes the bottom tube, the main connecting tube, and the secondary connecting tube. The supporting tube squeezes the main connecting tube downward, and the main connecting tube squeezes the anti-skid tube downward. The anti-skid tube is inserted into the ground to prevent the wheel mask from moving relative to the ground.

[0018] The technical effects of the present invention include:

[0019] The wheel block has a simple structure, high strength, and anti-skid function, which enables the mining dump truck to effectively stop on various road conditions. The wheel block is a triangular column structure with a rib plate in the middle of the triangular structure, which greatly enhances the structural strength of the wheel block to adapt to the huge deadweight of the mining dump truck.

[0020] Since the angle formed between the inclined surface of the wheel cover block and the ground is an acute angle, the wheel cover block can be better embedded in the gap between the ground and more stably support and restrict the movement of the wheel.

[0021] When the mask is placed at a corresponding position, the anti-skid tube can be inserted into the ground, thereby limiting the movement of the mask along the ground by the wheels, thereby limiting the movement of the dump truck.

[0022] Since the mask is welded with high-strength materials such as steel, stainless steel or titanium alloy, it has a large load-bearing capacity, will not be crushed by wheels, and has better reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The mining dump truck 1 is usually equipped with two wheel blocks 3. When the dump truck 1 is parked on a flat road, a wheel block 3 is usually placed on the front and rear sides of the wheel 10. The bottom surface of the wheel block 3 contacts the ground 2, and the inclined surface of the wheel block 3 contacts the wheel 10.

[0035] like Figure 3 As shown, it is a front structural schematic diagram of the wheel mask block 3 in the present invention; Figure 4 As shown, it is a schematic diagram of the back structure of the wheel mask block 3 in the present invention; Figure 5 , which is a schematic diagram of the side structure of the wheel mask 3 in the present invention.

[0036] The wheel mask 3 is a triangular column as a whole, including: a triangular frame 31, a main connecting pipe 32, a secondary connecting pipe 33 and an anti-skid pipe 34. Multiple triangular frames 31 are arranged in parallel, the main connecting pipe 32 is connected to the vertex positions of the multiple triangular frames 31, the secondary connecting pipe 33 is connected between two adjacent triangular frames 31, and multiple anti-skid pipes 34 are respectively connected to the side walls of the main connecting pipe 32.

[0037] The triangular frame 31 includes an inclined tube 31a, a bottom tube 31b, a support tube 31c and a rib plate 31d. The inclined tube 31a, the bottom tube 31b and the support tube 31c are connected end to end to form a triangular structure, and the rib plate 31d is connected to the side of the triangular frame 31.

[0038] The rib plate 31d is connected to the inclined tube 31a, the bottom tube 31b and the side wall of the support tube 31c. The rib plate 31d is provided with a plurality of circular holes 31d1 for weight reduction.

[0039] The wheel mask 3 is provided with three triangular frames 31 , and the three triangular frames 31 are arranged parallel to each other and at equal distances.

[0040] The main connecting pipe 32 is perpendicular to the triangular frame 31 , and the three main connecting pipes 32 are connected to the three vertices of the three triangular frames 31 respectively.

[0041] The secondary connecting pipes 33 are connected between adjacent secondary connecting pipes 33 and main connecting pipes 32, between adjacent inclined pipes 31a, and between adjacent bottom pipes 31b.

[0042] The wheel mask 3 has three anti-skid tubes 34 in total, and the bottom of the anti-skid tubes 34 has an inclined surface 34a.

[0043] The triangular frame 31 is fixedly connected integrally by the inclined tube 31a, the bottom tube 31b, the support tube 31c and the rib plate 31d by welding. The wheel mask 3 is fixedly connected integrally by the triangular frame 31, the main connecting tube 32, the secondary connecting tube 33 and the anti-skid tube 34 by welding.

[0044] How to use the wheel mask for a mining dump truck, the specific steps are as follows:

[0045] 1. When the dump truck 1 stops, a wheel mask 3 is placed on both sides of the front and rear of the wheel 10, the bottom tube 31b, the main connecting tube 32, and the secondary connecting tube 33 of the triangular frame 31 are in contact with the ground 2, and the inclined tube 31a, the main connecting tube 32, and the secondary connecting tube 33 are in contact with the wheel 10;

[0046] The triangular column wheel mask 3 has high overall strength, can provide strong support, and can more stably restrict the movement of the wheel 10.

[0047] 2. When the wheel 10 moves slightly, the wheel 10 squeezes the bottom tube 31b, the main connecting tube 32, and the secondary connecting tube 33. The support tube 31c squeezes the main connecting tube 32 downward, and the main connecting tube 32 squeezes the anti-skid tube 34 downward. The anti-skid tube 34 is inserted into the ground to prevent the wheel cover block 3 and the ground 2 from moving relative to each other, thereby effectively parking the mining dump truck and preventing the occurrence of slipping accidents.

[0048] The terms used in the present invention are illustrative and exemplary, rather than restrictive.
