Description

Technical Field

[0001] This utility model relates to an electric pump bracket, and more particularly to an electric pump bracket for a mining dump truck. Background Technology

[0002] Mining dump trucks are indispensable equipment in mining and transportation operations. They have a strong load-bearing capacity and can generally carry tens or even hundreds of tons of goods, efficiently transporting ore, slag and other materials mined from the mine to designated locations.

[0003] The electric pump in a mining dump truck supplies hydraulic oil to the hydraulic system, enabling the vehicle to steer. However, existing electric pump brackets are usually welded to the chassis. Due to the complex and diverse terrain and harsh environment in mining areas, mining trucks often experience vibrations and bumps when working in the mine. In addition, the electric pump also generates significant vibrations during operation. As a result, the electric pump bracket will reach its fatigue life earlier under the influence of internal and external factors, leading to cracks or breakage, which poses a serious safety hazard. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides an electric pump bracket for mining dump trucks. The electric pump is fixed on the base plate, which is fastened together by shock-absorbing pads and two sets of L-shaped support legs. The shock-absorbing pads and L-shaped support legs can effectively reduce the vibration generated when the vehicle is running and the vibration generated when the electric pump is working, preventing resonance between the pump and the motor pump bracket, and also solving the problem of insufficient strength of existing electric pump brackets.

[0005] To achieve the above objectives, one or more embodiments of this utility model provide the following technical solutions: An electric pump bracket for a mining dump truck includes L-shaped legs, a base plate, and shock-absorbing pads. The base plate has vertically penetrating shock-absorbing fixing holes at its four corners. L-shaped legs are symmetrically arranged on the lower left and right sides of the base plate. Shock-absorbing pads are installed between the L-shaped legs and the base plate. The number of shock-absorbing pads is the same as the number of shock-absorbing fixing holes, and their positions correspond vertically. The base plate is fixedly connected to the L-shaped legs by bolts and fasteners that pass through the shock-absorbing fixing holes and shock-absorbing pads in sequence.

[0006] Furthermore, several motor mounting holes are provided at the center-right position of the base plate, and the motor mounting holes are connected to the motor pump by bolts.

[0007] Furthermore, an oil suction pipe routing hole is provided on the left side of the motor mounting hole.

[0008] Furthermore, the bottom surface of the base plate is provided with first stiffening plates on both the front and rear sides, and the stiffening plates are located between the left and right L-shaped support legs.

[0009] Furthermore, the L-shaped support leg includes a support leg base plate, a vertical plate, a second stiffening plate, a third stiffening plate, and heightening shims. Two heightening shims are provided on the upper surface of the support leg base plate. The heightening shims adopt a circular structure. The two heightening shims are spaced a distance apart and are respectively arranged in a one-to-one correspondence with the shock-absorbing pads and shock-absorbing fixing holes on both sides of the base plate. The installation dimensions of the heightening shims and the shock-absorbing pads are adapted to each other.

[0010] Furthermore, the heightening shim is adapted to the installation dimensions of the shock-absorbing pad, and the heightening shim is provided with a rounded chamfer.

[0011] Furthermore, second stiffening plates are provided on both the left and right sides of the lower surface of the support leg base plate.

[0012] Furthermore, a vertical plate is connected to the upper surface of the support leg base plate on the side away from the base plate, and the vertical plate and the support leg base plate form an L-shaped support leg structure.

[0013] Furthermore, the upright plate is provided with several bolt holes from top to bottom, and the upright plate is connected to the vehicle frame by bolt fasteners.

[0014] Furthermore, there are two third stiffeners.

[0015] Furthermore, the structure of the third stiffener is approximately a transverse trapezoidal structure. The lower base of the third stiffener is fixed to the upright plate, the upper base is connected to the rear side of the base plate, and the height is fixedly connected to the upper surface of the support leg base plate.

[0016] Compared with the prior art, this utility model has at least the following advantages and beneficial effects: 1. In this utility model, the electric pump is fixed on the base plate, and the base plate is fastened to two sets of L-shaped support legs through shock-absorbing pads. The L-shaped support legs are connected to the vehicle frame through the upright plate. The shock-absorbing pads and L-shaped support legs can effectively reduce the vibration generated when the vehicle is running and the vibration generated when the electric pump is working, and prevent it from resonating with the motor pump bracket.

[0017] 2. The pads on the outrigger base plate can be adapted to different specifications of shock-absorbing pads. This design allows for the appropriate selection of the steel plate thickness of the outrigger base plate based on the specifications and dimensions of the shock-absorbing pads.

[0022] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention.

[0023] Where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0024] Example 1: like Figure 1 , Figure 2 and Figure 5As shown in the figure, this embodiment discloses an electric pump bracket for a mining dump truck, including an L-shaped support leg 1, a base plate 2, and a shock-absorbing pad 3. The base plate 2 is provided with shock-absorbing fixing holes 9 that run vertically through the four corners. The L-shaped support legs 1 are symmetrically arranged on the lower left and right sides of the base plate. The shock-absorbing pad 3 is provided between the L-shaped support leg and the base plate. The number of shock-absorbing pads and the shock-absorbing fixing holes 9 are the same and their positions correspond vertically. The base plate is fixedly connected to the L-shaped support leg 1 by fasteners 10 passing through the shock-absorbing fixing holes 9 and the shock-absorbing pad 3 in sequence.

[0025] Specifically, in this embodiment, the fastener 10 is a combination of bolts and nuts, and the shock-absorbing pad 3 adopts an upper and lower circular structure. The specific structure of the shock-absorbing pad 3 is as follows: Figure 6 As shown, the size of the central channel of the annular structure of the shock-absorbing pad is matched with the bolt size of the fastener. The bolt length of the fastener is greater than the total thickness of the three structures: the shock-absorbing fixing hole, the shock-absorbing pad, and the L-shaped support leg. This means that after the bolt passes through the shock-absorbing fixing hole 9, the shock-absorbing pad, and the L-shaped support leg from top to bottom, there will still be a protruding bolt part below the L-shaped support leg. The fixing between the base plate, the L-shaped support leg, and the shock-absorbing pad is achieved by the combination of the nut and the screw.

[0026] When vehicles operate within the mining area, the complex and diverse terrain inevitably causes vibrations and bumps. The shock-absorbing pads 3 located between the L-shaped outriggers and the base plate can absorb these vibrations during vehicle operation. Furthermore, the electric pump inside the vehicle also generates vibrations during operation. These vibrations can be reduced by the shock-absorbing pads, preventing resonance between the electric pump and its support. Specifically, when the vehicle is stationary, the electric pump vibrates, and the upper part of the shock-absorbing pad acts as a damper, reducing the vibrations generated during pump operation. When the vehicle is running, the pump and support vibrate vertically, and both the upper and lower parts of the shock-absorbing pad act as dampers.

[0027] like Figure 1 As shown, in order to ensure that the motor pump 5 can be installed on the base plate, several motor fixing holes 4 are provided at the middle right position of the base plate, and oil suction pipe arrangement holes 6 are provided on the left side of the motor fixing holes 4. Specifically, in this embodiment, there are four motor fixing holes 4, which are arranged in a rectangular shape. The motor fixing holes 4 can be connected to the motor pump 5 by bolts. The oil suction pipe arrangement holes 6 adopt a rectangular frame structure. After the motor pump is fixedly connected to the base plate, the various oil suction and discharge pipes of the motor pump 5 can be connected to the motor pump through the oil suction pipe arrangement holes 6.

[0028] In addition, in this embodiment, first stiffeners 2-1 are provided on both the front and rear sides of the lower surface of the base plate. The first stiffeners 2-1 are located between the L-shaped legs 1 on the left and right sides. The stability of the base plate structure itself is enhanced by the first stiffeners 2-1 on both sides of the lower surface of the base plate 2.

[0029] like Figure 3 As shown, the L-shaped support leg 1 in this embodiment includes a support leg base plate 1-1, a vertical plate 1-2, a second stiffening plate 1-4, a third stiffening plate 1-3, and a heightening shim 1-5. The vertical plate 1-2 is connected to the upper surface of the support leg base plate 1-1 away from the base plate 2. Both the support leg base plate 1-1 and the vertical plate 1-2 adopt a rectangular steel plate structure. The vertical plate and the support leg base plate form an L-shaped right angle structure. In order to better connect the frame and the motor pump, this embodiment provides several bolt holes 8 from top to bottom at the vertical plate. The L-shaped support leg 1 can be fixedly connected to the frame by bolt fasteners at the vertical plate. Since the L-shaped support leg is connected to the motor pump through the base plate, the motor pump and the frame are also fixedly connected in this embodiment.

[0030] like Figure 3 and Figure 4 As shown, in order to control the thickness of the steel plate of the outrigger base plate 1-1, this embodiment provides two raising shims 1-5 on the upper surface of the outrigger base plate. The raising shims 1-5 adopt a circular structure, with the two raising shims spaced a distance apart and corresponding one-to-one with the shock-absorbing pads 3 and shock-absorbing fixing holes 9 on both sides of the base plate 2. The installation dimensions of the raising shims and the shock-absorbing pads are adapted to each other. Since the raising shims 1-5 can be adapted to the installation dimensions of the shock-absorbing pads, the raising shims can be selected with a reasonable size according to the thickness of the shock-absorbing pads. This design can reduce the thickness of the steel plate of the outrigger base plate 1-1, saving materials while ensuring strength. Figure 4 As shown, the raised pads 1-5 have a rounded chamfer 7, that is, the rounded chamfer 7 is set at the middle edge of the circular ring of the raised pad. The structural design of the rounded chamfer can greatly increase the life of the shock-absorbing pad.

[0031] To enhance the structural strength of the L-shaped outrigger, this embodiment provides second stiffeners 1-4 on both the left and right sides of the lower surface of the outrigger base plate. The second stiffeners are approximately rectangular in shape. In addition, there are two third stiffeners 1-3. The structure of the third stiffeners is approximately a transverse trapezoidal structure. The lower base of the third stiffener is fixed to the upright plate, and the upper base is connected to the rear side of the base plate. The height of the transverse trapezoidal structure is fixedly connected to the upper surface of the outrigger base plate. Through the setting of the second and third stiffeners, the structural strength of the L-shaped outrigger can be greatly enhanced, making up for the problem of insufficient strength of the existing electric pump bracket.

[0032] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
