Through the reasonable layout of the first transverse reinforcing plate 151 and the second transverse reinforcing plate 152, a multi-dimensional support network is formed, which effectively improves the carrying capacity and anti-deformation capacity of the entire oil cavity structure 1 in different directions.

[0069] Please refer to Figure 2 In the embodiment, the first transverse reinforcing plate 151 and the second transverse reinforcing plate 152 each have a second slot hole 156 extending front and back, Figure 2As shown, the second slot hole 156 is located at the lower part of the transverse reinforcing plate, so that the transverse reinforcing plate forms a concave shape. The first transverse reinforcing plate 151 and the second transverse reinforcing plate 152 both support the upper cover plate 13. The first transverse reinforcing plate 151 and the second transverse reinforcing plate 152 support the upper cover plate 13, and by arranging the second slot hole 156 on the transverse reinforcing plate, the amount of material is reduced, and cost savings are achieved without affecting the structural strength.

By arranging the third slot hole 157 on the longitudinal reinforcing plate 153, the amount of material is reduced, and cost savings are achieved without affecting the structural strength. The pump bracket 5 can be arranged in front of the front wall 121 and stably connected to the front wall 121 through appropriate connecting members. The longitudinal reinforcing plate 153 reinforces the frame at the position of the step 159, and enhances the overall rigidity and stability of the oil tank structure 1.

[0072] Referring to Figure 2 In this embodiment, the reinforcing plate 15 includes an inclined reinforcing plate 154 arranged obliquely on the frame and supporting the left wall 123 or the right wall 124.

By connecting the inclined reinforcing plate 154 with the left wall 123 or the right wall 124, the pressure acting on the side wall can be more effectively dispersed, and the risk of deformation or damage due to local stress concentration can be reduced.

[0073] Referring to Figure 2In the embodiment, the oblique reinforcing plate 154 has a fourth through-hole 158 on the side facing the inner side of the frame. Figure 2 It is shown that the fourth through-hole 158 is located on the inner side of the oblique reinforcing plate 154, so that the oblique reinforcing plate 154 forms a concave shape. By providing the fourth through-hole 158 on the oblique reinforcing plate 154, the amount of material is reduced, and cost savings are achieved without affecting the structural strength.

[0076] Please refer to Figure 1 In the embodiment, the plurality of surrounding plates further includes a left surrounding plate 123 and a right surrounding plate 124, and the frame further comprises a left frame body 3 and a right frame body 4. The left frame body 3 is located on the left side of the left surrounding plate 123 and the pump support 5, and is connected with the pump support 5. The left frame body 3 and the pump support 5 are connected through a reinforcing pull rod 6. The right frame body 4 is located on the right side of the right surrounding plate 124 and the pump support 5, and is connected with the pump support 5. The right frame body 4 and the pump support 5 are connected through a reinforcing pull rod 6.

Figure 1 It is shown that the length of the left frame body 3 and the right frame body 4 is slightly longer than the length of the oil cavity structure 1 and the pump support 5. The reinforcing pull rod 6 firmly connects the pump support 5 with the left frame body 3 and the right frame body 4, so that the vibration and impact force generated during the operation of the pump body can be evenly dispersed to the entire frame through multiple paths, reducing the risk of local stress concentration.

[0077] Please refer to Figure 1 and Figure 2 In the embodiment, the frame has a plurality of connecting plates 7, each of which has a positioning hole 71 passing through up and down, so that the bolt passes through the positioning hole 71 to assemble the frame on the chassis 10 of the mobile pump station. The position and number of the connecting plates 7 are optimized according to actual needs to ensure that the frame can be stably and reliably fixed on the chassis 10.

By adding the support structures 2, the area of the cover plate 13 is effectively expanded, and a solid and stable foundation is provided for the installation of the engine 8. In addition, the hollow design of the support structures 2 not only reduces the weight, but also provides additional space for wiring or other auxiliary equipment, improving the space utilization.

[0079] In the embodiment, the oil inlet and the oil outlet are preferably arranged on the cover plate 13, and can also be arranged on the front surrounding plate 121, the rear surrounding plate 122, the left surrounding plate 123, or the right surrounding plate 124.

[0080] In the embodiment, the bottom plate and the surrounding plates are bent from one plate, or the cover plate and the surrounding plates are bent from one plate. As an implementation, the bottom plate, together with the front surrounding plate and the rear surrounding plate, can be bent from one plate, and the cover plate, together with the left surrounding plate and the right surrounding plate, can be made from one plate. Then, these components can be precisely assembled together, such as welding, to jointly form a closed oil cavity, ensuring the stability and sealing of the overall structure. In addition, there are various implementation modes to choose from, for example, the bottom plate, together with the left surrounding plate and the right surrounding plate, can be bent together, and the cover plate, together with the front surrounding plate and the rear surrounding plate, can be bent together. This means that the structure that can originally be welded or assembled from multiple plates is now bent into the required shape through a specific process of the plate, which can reduce the potential leakage risk caused by the connection mode such as welding, and has small deformation and good structural strength.

[0081] In some embodiments, the surrounding plates include the front surrounding plate, the rear surrounding plate, the left surrounding plate, and the right surrounding plate that are bent, i.e., the front surrounding plate, the rear surrounding plate, the left surrounding plate, and the right surrounding plate can be bent from one plate, and then assembled with the bottom plate and the cover plate.

The engine 8 is arranged on the cover plate 13 of the frame, and the engine 8 is connected to the oil outlet and the oil return of the oil cavity structure through an oil pipe. Fuel flows from the oil outlet to the engine for use by the engine, and the engine that is not completely combusted then enters the oil cavity structure through the oil return. The water pump 9 is connected to the engine 8. The frame in combination with the overall layout of the mobile pump station provides a more compact, stable, and efficient solution.

[0083] Referring to Figure 4 In the embodiment, the chassis 10 is a tracked chassis 10, which has better grip and passability than the wheeled chassis 10, and is especially suitable for traveling on muddy, soft or uneven ground, ensuring efficient operation of the mobile pump station in various complex environments.
