Description

Technical Field

[0001] The utility model relates to a body liner of a mining dump truck, in particular to a lightweight body liner porous plate of the mining dump truck. Background Art

[0002] A mining truck is a heavy-duty dump truck used in open-pit mines to complete rock and earth stripping and ore transportation tasks. Its working characteristics are short haul distance and heavy load. Large electric shovels or hydraulic shovels are often used for loading, and it travels back and forth between the mining site and the unloading site. In the mining and quarrying industries, mining trucks are the key to efficient and high-productivity operations. Trucks work closely with other mining equipment and must work continuously for many days in a single operation. Under such harsh working conditions, mining trucks are required to operate stably and reliably.

[0003] The hopper of a mining truck is a device for holding bulk materials. The frame is a load-bearing structure. Its operation process is mainly divided into three stages: loading, transporting, and unloading. The existing minerals will be directly loaded on the truck hopper. During the loading process, the minerals will be directly dumped into the car body through an excavator or other loading and unloading equipment. During the long-term transportation process, the minerals will generate friction between the car body and the mining dump truck car body. Long-term friction will cause wear on the inner wall of the car body and even cause partial damage to the car body, which greatly reduces the life of the car body. To address the above problems, a solution is proposed below. Utility Model Content

[0004] The purpose of the utility model is to provide a lightweight body lining porous plate for a mining dump truck, which solves the problem proposed in the above background technology that the existing minerals are directly loaded on the carriage during transportation, and the minerals will generate friction with the carriage during transportation. Long-term friction will cause wear and damage to the carriage.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A lightweight body lining porous plate for a mining dump truck, comprising a carriage, a plurality of wear-resistant fixed lining plates and a plurality of wear-resistant porous lining plates, wherein the wear-resistant fixed lining plates and the wear-resistant porous lining plates are fixed to the inner bottom wall of the carriage by welding, and through holes are provided on the wear-resistant fixed lining plates and the wear-resistant porous lining plates, through holes are provided on both ends and the middle of the wear-resistant fixed lining plate, and a plurality of through holes are evenly distributed on the wear-resistant porous lining plate, the wear-resistant fixed lining plate is fixed to the middle position of the inner bottom wall of the carriage and the loading and unloading position of the carriage mouth, and the wear-resistant porous lining plate is welded to the remaining parts of the carriage.

[0007] Preferably, a number of wear-resistant porous lining plates are evenly distributed on the inner wall of the carriage, and each of the wear-resistant fixed lining plates and each of the wear-resistant porous lining plates are installed in a non-contact manner, with a gap left between each of the wear-resistant fixed lining plates and each of the wear-resistant porous lining plates.

[0008] Preferably, the thickness of the wear-resistant fixed liner plate and the wear-resistant porous liner plate are both 14-16 mm.

[0009] Preferably, the wear-resistant fixed liner plate and the wear-resistant porous liner plate are both made of NM500 high-strength wear-resistant steel plate.

[0010] Preferably, the through hole may be any one of circular, hexagonal and square.

[0011] Beneficial effects: By installing wear-resistant fixed lining plates and wear-resistant porous lining plates in the car body, the car body can be protected, the friction between the minerals and the car body can be prevented, and the service life of the car body is improved. The several through holes opened on the wear-resistant fixed lining plates and the wear-resistant porous lining plates reduce the dead weight of the material. The wear-resistant fixed lining plates and the wear-resistant porous lining plates are installed non-contactly, thereby further reducing the number of wear-resistant fixed lining plates and wear-resistant porous lining plates installed, reducing the impact on the loading weight of the truck, and reducing energy consumption.

[0016] See Figures 1 to 3 As shown, a lightweight body lining porous plate of a mining dump truck includes a car body 1, a plurality of wear-resistant fixed lining plates 2 and a plurality of wear-resistant porous lining plates 3. The wear-resistant fixed lining plates 2 and the wear-resistant porous lining plates 3 are fixed to the inner bottom wall of the car body 1 by welding. The wear-resistant fixed lining plates 2 and the wear-resistant porous lining plates 3 are fixed to the car body 1 by welding, so that the fixing strength of the wear-resistant fixed lining plates 2 and the wear-resistant porous lining plates 3 is high, and no additional connecting parts are required, which saves materials and reduces weight.

[0017] The wear-resistant fixed lining plate 2 and the wear-resistant porous lining plate 3 are both provided with through holes 4. The wear-resistant fixed lining plate 2 and the wear-resistant porous lining plate 3 can reduce the weight of the two plates by opening through holes 4. The wear-resistant fixed lining plate 2 has through holes 4 at both ends and in the middle. A number of through holes 4 are evenly distributed on the porous lining plate. The wear-resistant fixed lining plate 2 is fixed to the middle position of the bottom wall of the carriage 1 and the loading and unloading position of the carriage 1. The wear-resistant porous lining plate 3 is welded to the rest of the carriage 1. 1 Wear-resistant fixed lining plates 2 are laid on the positions on the inner bottom wall that bear more weight and at the vehicle box opening where there is more friction during loading and unloading. Since the wear-resistant fixed lining plates 2 are installed at the positions that bear more weight, fewer through holes 4 are provided on the wear-resistant fixed lining plates 2, and the wear-resistant fixed lining plates 2 mainly play the role of bearing weight. Wear-resistant porous lining plates 3 are laid on the other positions. The wear-resistant porous lining plates 3 have less requirements for bearing weight, so a number of through holes 4 are evenly provided on the wear-resistant porous lining plates 3, thereby achieving the effect of reducing weight.

[0018] A number of wear-resistant porous lining plates 3 are evenly distributed on the inner wall of the car body 1. By installing the wear-resistant porous lining plates 3 on the inner wall, the inner wall of the car body 1 can be protected, thereby reducing the friction of the mineral on the car body 1. Each wear-resistant fixed lining plate 2 and each wear-resistant porous lining plate 3 are welded in a non-contact installation. A gap is left between each wear-resistant fixed lining plate 2 and each wear-resistant porous lining plate 3 during installation. The non-contact installation between the wear-resistant fixed lining plate 2 and the wear-resistant porous lining plate 3 further reduces the number of wear-resistant fixed lining plates 2 and wear-resistant porous lining plates 3 installed, reduces the impact on the truck loading weight, and reduces energy consumption.

[0019] The wear-resistant fixed liner plate 2 and the wear-resistant porous liner plate 3 are both made of NM500 high-strength wear-resistant steel plate. The use of high-strength wear-resistant steel plate can increase the service life of the wear-resistant fixed liner plate 2 and the wear-resistant porous liner plate 3, so that the wear-resistant fixed liner plate 2 and the wear-resistant porous liner plate 3 can better protect the carriage 1. The thickness of the wear-resistant fixed liner plate 2 and the wear-resistant porous liner plate 3 are both 16 mm. By designing the wear-resistant fixed liner plate 2 and the wear-resistant porous liner plate 3 to 16 mm, the thickness of the wear-resistant fixed liner plate 2 and the wear-resistant porous liner plate 3 can be minimized while ensuring the strength of the wear-resistant fixed liner plate 2 and the wear-resistant porous liner plate 3, thereby reducing their weight.

[0020] In the present application, the through hole 4 of the wear-resistant fixed liner plate 2 adopts a circular hole structure. Since the wear-resistant fixed liner plate 2 is a load-bearing plate, it has a relatively simple circular hole structure, which is convenient for construction and design. The wear-resistant porous liner plate 3 adopts a hexagonal structure. The load-bearing requirement of the wear-resistant porous liner plate 3 is relatively small, so its through hole 4 adopts a hexagonal structure, so that more through holes 4 can be opened on the wear-resistant porous liner plate 3 to achieve maximum weight reduction.
