Description

Technical Field

[0001] This utility model relates to the field of dump truck technology, and in particular to a mining dump truck. Background Technology

[0002] Mining dump trucks are heavy-duty transport vehicles specifically designed for environments such as mines, quarries, and large-scale earthwork projects. They are mainly used for transporting and unloading bulk materials such as ore, coal, and sand. Due to the special characteristics of mining dump trucks, they are equipped with a hydraulic system, which uses hydraulic oil to achieve steering and lifting functions.

[0003] Currently, the hydraulic oil tank and functional pump sets (at least including steering pump set and lifting pump set) in mining dump trucks are installed separately. This results in a large installation space required for the hydraulic system, and the connecting pipes between the hydraulic oil tank and the functional pump set are too long, which brings great inconvenience to the installation and maintenance of the hydraulic system.

Furthermore, in the specification, unless explicitly stated otherwise, the word "comprising" will be understood to mean including the stated component, but not excluding any other components.

[0025] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] like Figure 1 As shown, this embodiment of the present invention provides a mining dump truck 10. The mining dump truck 10 provided in this embodiment of the present invention, for example, integrates a hydraulic system to fulfill the functional requirements of the mining dump truck, such as steering and lifting.

[0027] For details, see Figure 1 and Figure 2 The mining dump truck 10 includes, for example, a frame body 100, a hydraulic oil tank bracket 110, a hydraulic oil tank 200, a lifting pump assembly 300, and a steering pump assembly 400. The frame body 100, for example, is equipped with a lifting pump motor bracket 120, and the hydraulic oil tank 200 is mounted on the frame body 100 via the hydraulic oil tank bracket 110. Specifically, the hydraulic oil tank 200 is secured to the hydraulic oil tank bracket 110 by four steel connecting straps with T-bolts and nuts. A lift pump assembly 300 is located on one side of the hydraulic oil tank 200 and mounted on the vehicle frame body 100 via a lift pump motor bracket 120. The lift pump assembly 300 includes a lift pump motor 310 and a lift pump 320 connected to each other. The lift pump motor 310 is mounted on the lift pump motor bracket 120, and the suction port of the lift pump 320 is connected to the interior of the hydraulic oil tank 200. The lift pump motor 310 drives the lift pump 320. A steering pump assembly 400 is located on one side of the hydraulic oil tank 200 and mounted on the hydraulic oil tank bracket 110. The steering pump assembly 400 includes a steering pump motor 410 and a steering pump 420 connected to each other. The steering pump motor 410 is mounted on the hydraulic oil tank bracket 110, and the steering pump motor 410 drives the steering pump 420. The suction port of the steering pump 420 is connected to the interior of the hydraulic oil tank 200.

[0028] The mining dump truck provided in this embodiment effectively reduces the required installation space by centrally mounting the hydraulic oil tank and pump unit on the main body of the vehicle frame, shortens the connecting pipeline between the pump unit and the hydraulic oil tank, and makes the structure between the pump unit and the hydraulic oil tank compact. This facilitates the installation, commissioning and maintenance of the mining dump truck, and also reduces the failure rate and maintenance cost of the mining dump truck.

[0029] In existing hydraulic systems, the hydraulic pump assembly is horizontally mounted. To ensure oil pump suction, the hydraulic oil tank and pump are typically staggered vertically, or the ineffective volume of the hydraulic oil tank is increased. This application addresses this issue by placing the suction ports of the lifting pump 320 and the steering pump 420 below the bottom surface of the hydraulic oil tank 200. This facilitates oil suction for the lifting pump 320 and the steering pump 420 while eliminating the need to increase the ineffective volume of the hydraulic oil tank 200.

[0030] For details, see Figure 1 and Figure 3 The frame body 100 includes a first end 101 and a second end 102 disposed opposite to each other. The hydraulic oil tank bracket 110 has three hydraulic oil tank mounting brackets 111 at both ends. One of the three hydraulic oil tank mounting brackets 111 is fixedly connected to one end of the first end 101 and the second end 102, and the other two hydraulic oil tank mounting brackets 111 are fixedly connected to the other end of the first end 101 and the second end 102. That is, the hydraulic oil tank bracket 110 is fixedly mounted to the frame body 100 by the three hydraulic oil tank mounting brackets 111. One hydraulic oil tank mounting bracket 111 is located at one end of the frame body 100, and the other two are located at the other end. This design reduces the impact of deformation on the hydraulic oil tank bracket 110 when the frame body 100 deforms.

[0031] As stated above, see also Figure 4 The hydraulic oil tank bracket 110 is mounted on both sides of the vehicle frame body 100, and a rubber pad 500 is provided between the hydraulic oil tank bracket 110 and the vehicle frame body 100. By providing the rubber pad 500, the impact of inconsistent deformation on both sides of the vehicle frame body 100 on the hydraulic oil tank bracket 110 can be reduced.

[0032] Further, see Figure 1 and Figure 2The lifting pump assembly 300 and the steering pump assembly 400 are located, for example, on the same side of the hydraulic oil tank 200. This allows for a more compact installation between the hydraulic oil tank 200 and the pump assembly, thereby further reducing the required installation space.

[0033] In one specific implementation, see Figure 2 The lift pump motor bracket 120 is located at one end of the vehicle frame body 100. By directly connecting the lift pump motor 310 to one end of the vehicle frame body 100, the volume of the lift pump motor bracket 120 can be reduced. This avoids deformation of the lift pump motor bracket 120 due to inconsistent deformation at both ends of the vehicle frame body 100, and also reduces the impact of vibration from the lift pump motor 310 on the deformation of the vehicle frame body 100.

[0034] As stated above, see also Figure 2 The axial direction of the lifting pump motor 310 is perpendicular to the plane of the hydraulic oil tank bracket 110, meaning that the lifting pump motor 310 and the lifting pump 320 are vertically mounted relative to the hydraulic oil tank bracket 110. Further, the lifting pump motor 310 is equipped with a first mounting flange and a first internal spline coupling, and the lifting pump 320 is equipped with a second mounting flange and a first external spline coupling. The first and second mounting flanges are connected, and the first internal spline coupling and the first external spline coupling are also connected. The first and second mounting flanges are, for example, SAE C shaft end flanges. By vertically mounting the lifting pump motor 310 and the lifting pump 320 and directly connecting them via flanges and splines, the space occupied by the lifting pump assembly can be reduced, thereby lowering the failure rate and maintenance costs.

[0035] In one specific implementation, see Figure 2 A steering pump motor bracket 130 is provided on the hydraulic oil tank bracket 110, and the steering pump motor 410 is mounted on the steering pump motor bracket 130. The axial direction of the steering pump motor 410 is perpendicular to the plane of the hydraulic oil tank bracket 110. That is, the steering pump motor 410 and the steering pump 420 are vertically mounted relative to the hydraulic oil tank bracket 110. Further, see also... Figure 2 The steering pump motor 410 is equipped with a third mounting flange and a second internal spline coupling, and the steering pump 420 is equipped with a fourth mounting flange and a second external spline coupling. The third and fourth mounting flanges are connected, and the second internal spline coupling is connected to the second external spline coupling. The third and fourth mounting flanges are, for example, SAE B shaft end flanges. By vertically mounting the steering pump motor 410 and the steering pump 420 and directly connecting them via flanges and splines, the space occupied by the steering pump assembly can be reduced, thereby lowering the failure rate and maintenance costs.

[0036] In summary, the mining dump truck provided in this embodiment effectively reduces the required installation space by centrally mounting the hydraulic oil tank and pump unit on the main body of the vehicle frame, shortens the connecting pipeline between the pump unit and the hydraulic oil tank, and makes the structure between the pump unit and the hydraulic oil tank compact. This facilitates the installation, commissioning and maintenance of the mining dump truck, and also reduces the failure rate and maintenance cost of the mining dump truck.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
