[0026] As mentioned above, underground coal transport vehicles typically operate in mine roadways. The geological conditions around these roadways are complex, with potential faults, fissures, and other geological structures that can easily cause falling rocks to collide with the hydraulic pump motor housing. Furthermore, the narrow roadway space makes it difficult to maintain the hydraulic pump motor housing, and maintenance access is often lacking.

[0027] To address at least one of the technical problems existing in the prior art or related technologies, this application provides a hydraulic oil pump motor housing for underground coal transport vehicles and the coal transport vehicle itself. The hydraulic oil pump motor housing for underground coal transport vehicles includes: a base plate; a back plate disposed on the base plate; a first side plate and a second side plate respectively connected to the base plate and the back plate, with ear plates provided on both sides of the first and second side plates respectively; a top plate disposed above the first side plate, the second side plate, and the back plate; the top plate and the ear plates forming an anti-collision zone; and a front panel detachably connected to the first and second side plates via a connecting mechanism. Through the synergistic effect of the ear plates and the top plate, impact resistance can be effectively improved, solving the problem of insufficient protection and anti-collision levels; the front panel can be quickly disassembled, improving maintenance convenience and solving the problem of lack of inspection access.

[0028] The following description, with reference to the accompanying drawings, describes some embodiments of a hydraulic oil pump motor box and a coal transport vehicle according to the present application.

[0029] See Figures 1 to 2 This application provides a hydraulic oil pump motor box for underground coal transport vehicles, comprising: a base plate 1; a back plate 2 disposed on the base plate 1; a first side plate 4 and a second side plate 5 respectively connected to the base plate 1 and the back plate 2, the back plate 2 having ear plates 21 on both sides of the first side plate 4 and the second side plate 5; a top plate 3 disposed above the first side plate 4, the second side plate 5 and the back plate 2; the top plate 3 and the ear plates 21 forming an anti-collision area 8; and a front panel 6 detachably connected to the first side plate 4 and the second side plate 5 respectively via a connecting mechanism 7.

[0030] The base plate 1, back plate 2, top plate 3, first side plate 4, and second side plate 5 form a sealed enclosure that protects the internally installed hydraulic pump and oil pump motor from external environmental factors such as dust and moisture. The base plate 1, designed in a rectangular shape, supports the weight of the entire enclosure as well as the hydraulic pump and oil pump motor. It can be made of high-strength metal materials such as stainless steel, aluminum alloy, or cast iron to ensure durability. The back plate 2 is mounted on the base plate 1, forming the rear of the enclosure. Ear plates 21 are located on both sides of the back plate 2, outside the first side plate 4 and second side plate 5. The top plate 3 also extends from the outside of the first side plate 4 and second side plate 5 above the ear plates 21. The ear plates 21 and the top plate 3 together form an impact-resistant zone 8, which improves the enclosure's impact resistance and enhances the overall structural stability, making it less prone to deformation under impact. The front panel 6 is designed to be completely detachable via a connecting mechanism 7, greatly facilitating maintenance and repair of the enclosure and effectively solving the problem of insufficient maintenance access.

[0031] In one illustrative embodiment, the connecting mechanism 7 includes an upper pin 71 and a lower pin 72, which are detachably connected by passing through a sleeve. The sleeve is disposed on the front panel 6, the first side plate 4, and the second side plate 5.

[0032] During installation, the upper pin 71 first passes through the sleeve above the first side plate 4, and then through the sleeve above the side of the front panel 6 near the first side plate 4; simultaneously, the lower pin 72 first passes through the sleeve below the first side plate 4, and then through the sleeve below the side of the front panel 6 near the first side plate 4, thus connecting the upper pin 71 and the lower pin 72 together. Similarly, the installation process of the upper pin 71 and the lower pin 72 on the second side plate 5 is the same, and will not be described again here.

[0033] During disassembly, the upper pin 71 and lower pin 72 on one side of the first side plate 4 can be disconnected first, and then the upper pin 71 and lower pin 72 can be removed, allowing the front panel 6 to rotate and open around the upper pin 71 and lower pin 72 on one side of the second side plate 5. Similarly, the upper pin 71 and lower pin 72 on one side of the second side plate 5 can be disconnected first, and then the upper pin 71 and lower pin 72 can be removed, allowing the front panel 6 to rotate and open around the upper pin 71 and lower pin 72 on one side of the first side plate 4. Alternatively, both the upper pin 71 and lower pin 72 of the first side plate 4 and the second side plate 5 can be removed, completely disconnecting the front panel 6 from the first side plate 4 and the second side plate 5. This design allows the front panel 6 to be opened by rotating on one side or disassembled as a whole, enabling operators to choose the appropriate disassembly method according to actual needs, thereby allowing faster access to the interior of the enclosure and improving maintenance and repair efficiency.

[0034] In one illustrative embodiment, the upper pin 71 and the lower pin 72 are detachably connected by a threaded connection. Each end of the upper pin 71 and the lower pin 72 has a stud and a mating threaded sleeve. For example, one end of the upper pin 71 has a stud, and one end of the lower pin 72 has a threaded sleeve. By rotating the upper pin 71 or the lower pin 72, the stud engages tightly with the thread inside the sleeve, thus achieving the connection. When disassembly is required, simply rotate the upper pin 71 or the lower pin 72 in the opposite direction to easily separate them. The threaded connection design makes the disassembly and reinstallation of the upper pin 71 and the lower pin 72 simple and quick. Simultaneously, the threaded connection provides strong tensile and shear force resistance, ensuring the connection mechanism 7 remains stable when subjected to the weight of the housing and external impact forces.

[0035] In one illustrative embodiment, a first fixing plate 11 is provided on the base plate 1, which is used to fix the hydraulic pump. The first fixing plate 11 is a support frame designed according to the hydraulic pump, and the hydraulic pump can be completely fitted into the first fixing plate 11 after installation, so as to achieve stable support and fixation.

[0036] In one illustrative embodiment, a second fixing plate 12 is provided on the base plate 1, which is used to fix the oil pump motor. The second fixing plate 12 can be designed as a long strip with a U-shaped cross-section. The U-shaped cross-section design creates a gap between the oil pump motor and the base plate 1, which can more effectively bear the weight of the oil pump motor and absorb and disperse the vibration energy of the oil pump motor during operation, ensuring that the oil pump motor remains stable during operation.

[0037] Furthermore, the connection between the second fixed plate 12 and the oil pump motor is provided with shock-absorbing pads, such as rubber pads, silicone pads, polyurethane pads and other elastic materials. These materials have good shock absorption performance and wear resistance, and can effectively absorb and disperse vibration energy, which helps to improve the stability and reliability of the oil pump motor and extend the service life of the oil pump motor.

[0038] In one illustrative embodiment, the second side panel 5 has a bending area. The bending area is a protrusion that extends outward from the second side panel 5, i.e., the flat plate is bent to create an angle. In use, the second side panel 5 is close to the outer side of the vehicle body and is easily impacted by falling rocks. The design of the bending area gives the second side panel 5 an outward protrusion, increasing the structural toughness of the second side panel 5 and enabling it to better resist deformation and breakage when facing external impacts.

[0039] In one illustrative embodiment, a maintenance cover 51 is provided on the second side plate 5. The maintenance cover 51 can be detachably connected to the second side plate 5 by bolts. The design of the maintenance cover 51 allows operators to easily access the oil pump motor to perform necessary inspections, cleaning, maintenance or replacement work, effectively solving the problem of missing maintenance access.

[0040] In one illustrative embodiment, a top cover plate 31 is provided on the top plate 3. The top cover plate 31 can be detachably connected to the top plate 3 by bolts. By providing the top cover plate 31, operators can more easily clean and maintain the area below the top plate 3, effectively solving the problem of missing maintenance access.

[0041] In one illustrative embodiment, the top cover 31 is provided with a handle 32. Two handles 32 may be provided, allowing the operator to easily move the top cover 31 for maintenance.
