Those skilled in the art will think of other modifications within the scope and spirit of the present utility model.

[0026] The drawings included in the specification and forming a part of the specification illustrate embodiments of the present utility model, and together with the general description of the present utility model given above and the detailed description of the embodiments given below are used to explain the principles of the present utility model.

[0027] By the following description of the preferred forms of the embodiments given as non - restrictive examples with reference to the drawings, these and other characteristics of the present utility model will become apparent.

[0029] When combined with the drawings, in view of the following detailed description, the above and other aspects, features and advantages of the present utility model will become more apparent.

[0030] Specific embodiments of the present invention will be described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments claimed are merely examples of the present invention, which can be implemented in various ways. Well-known and / or repetitive functions and structures are not described in detail to avoid obscuring the present invention with unnecessary or redundant details. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but are merely a basis and representative basis for the claims to teach those skilled in the art to use the present invention in substantially any suitable detailed structure in a variety of ways.

[0031] The first embodiment of the present invention provides a hydraulic pump station, as Figures 1 - 4 shown, the hydraulic pump station includes a flatbed truck 1, a hydraulic pump assembly 2 and a jack assembly 3 are arranged on the flatbed truck 1, the jack assembly 3 includes a driving device 32 and a plurality of jacks 31, the jacks 31 are arranged at the bottom of the flatbed truck 1 and can extend towards the ground so that the wheels 11 of the flatbed truck 1 are suspended.

[0032] In some embodiments, the jack 31 is a hydraulic jack, which is the working device for lifting the flatbed truck 1. The jack assembly 3 includes a jack 31 and a driving device 32, and the jack 31 is installed at the bottom of the flatbed truck 1. The driving device 32 is installed at the end of the flatbed truck 1, and the installation position of the driving device 32 is reasonably arranged to facilitate the operation of the driving device 32 to make the jack assembly 3 work.

[0033] When moving underground, there is a safety distance between the jack 31 of the hydraulic pump station and the ground, and the flatbed truck 1 moves through its wheels 11; after the hydraulic pump station moves to the working location, if the entire hydraulic pump station is supported by the wheels 11, due to the small contact area between the wheels 11 of the flatbed truck 1 and the ground, the stability is weak, and the overall vibration of the hydraulic pump station during the operation of the hydraulic pump assembly 2 will be very large. In this embodiment, a jack 31 is installed at the bottom of the flatbed truck 1, and the jack 31 can extend towards the ground to lift the flatbed truck 1. At this time, the wheels 11 of the flatbed truck 1 remain suspended. The flatbed truck 1 contacts the ground through the jack 31. Since the contact area between the jack 31 and the ground is large, the stability is higher, and the vibration of the hydraulic pump assembly 2 during operation is much smaller than that supported by the wheels 11 of the flatbed truck 1, which is beneficial to improving the service life of the entire hydraulic pump station.

[0034] In some prior arts, after the hydraulic pump station is transported to the working location, it is necessary to remove the wheels 11 of the flatbed truck 1 to make the flatbed truck 1 have a larger contact area with the ground before working. However, the method of installing the wheels 11 during the transportation of the hydraulic pump station and removing the wheels 11 during work is troublesome to disassemble and assemble, time-consuming and laborious, and affects the work efficiency. In this embodiment, the wheels 11 are suspended, and it is not necessary to remove the wheels 11 during the operation of the hydraulic pump station, saving the time for disassembling and assembling the wheels 11 and improving the work efficiency.

[0035] This hydraulic pump station can take into account both the convenience of moving the hydraulic pump station underground and the stability during the operation of the hydraulic pump station, reduce the vibration generated during the operation of the hydraulic pump station, and improve the service life of the entire hydraulic pump station.

[0036] The hydraulic pump assembly 2 includes a crankcase 4. Exemplarily, the hydraulic pump is a piston pump, and correspondingly, the hydraulic pump station is a piston pump station.

[0037] In some embodiments, the jack 31 includes a base 311, the base 311 is connected to the driving device 32, and the base 311 is connected to the piston part 313 through a piston rod 312. The base 311 is used to be fixed to the flatbed truck 1. Among them, one side of the base 311 is connected to the bottom of the flatbed truck 1 by bolts or by welding, and the other end of the base 311 is connected to the piston part 313 through the piston rod 312. The piston rod 312 can move along the piston part 313, and the extended length of the piston rod 312 can be adjusted. As the extended length of the piston rod 312 becomes larger, the jack 31 contacts the ground and the wheels 11 of the flatbed truck 1 are disengaged from the ground, that is, the wheels 11 are suspended.

[0038] In some embodiments, the driving device 32 is arranged at the end of the flatbed truck 1, making it easier for the operator to operate the driving device 32.

[0039] Taking the driving device 32 as a manual pump as an example for illustration. The manual pump is the power source of the jack 31. By continuously pressing the handle, the pressure of the working medium can be increased, and the piston rod 312 of the jack 31 can be extended through the pipeline, thereby lifting the flatbed truck 1. When the hydraulic pump station is transported by the wheels 11, the piston rod 312 does not extend; when the hydraulic pump station reaches the working location, the piston rod 312 extends and supports on the ground, lifting the flatbed truck 1. Among them, according to requirements, the driving device 32 can also be set as an electric pump or a pneumatic pump that saves manpower and is convenient to operate.

[0040] In some embodiments, the jack 31 is arranged near the end of the flatbed truck 1. Exemplarily, two jacks 31 are respectively arranged at the left and right ends of the flatbed truck 1. The two jacks 31 at one end of the flatbed truck 1 can be driven by one driving device 32, improving work efficiency and reducing costs. It is also possible to configure a separate driving device 32 for each jack 31, and each driving device 32 works independently, with higher working stability. Among them, a plurality of jacks 31 are arranged at the bottom of the flatbed truck 1, and the bottom of the flatbed truck 1 has a plurality of support points, further increasing the contact area between the flatbed truck 1 and the ground, which is beneficial to improving the stability of the hydraulic pump station.

[0041] Further, the hydraulic pump station is moved to the working location underground by the flatbed truck 1. The flatbed truck 1 is lifted by the jack 31, and the wheels 11 of the flatbed truck 1 are in a suspended state. Then, wooden blocks 9 are installed between the bottom of the flatbed truck 1 and the ground to make the jack 31 suspended (or the jack 31 in contact with the ground). Subsequently, the hydraulic pump station starts to work. In this way, when the hydraulic pump station works, it is supported as a whole by the wooden blocks 9. The contact area between the hydraulic pump station and the ground is larger, enhancing the stability of the hydraulic pump station, and the vibration of the hydraulic pump station during operation is smaller.

[0042] Exemplarily, the wooden blocks 9 can be arranged along the length direction of the flatbed truck 1 or along the width direction of the flatbed truck 1. And after the wooden blocks 9 between the flatbed truck 1 and the ground are installed, the piston rod 312 of the jack 31 can be retracted, which is beneficial to extending the service life of the jack 31.

[0043] In some embodiments, a plurality of wooden blocks 9 can be provided, and the wooden blocks 9 are arranged between the jack 31 and the wheels 11, so that the pressure of the hydraulic pump station on the support member 51 is evenly distributed.

[0044] Among them, the flatbed truck 1 is a platform device for supporting the hydraulic pump assembly 2, which is welded by a plurality of structural members such as steel sections and plates.

[0045] Exemplarily, the wheels 11 at the bottom of the flatbed truck 1 can be set as rubber wheels, which is convenient for the flatbed truck 1 to be transported underground. The flatbed truck 1 with the jack assembly 3 can also be applied to the transportation of other equipment that needs to be transported underground in mines.

[0046] A crankcase 4 is installed on the flatbed truck 1, and a first motor 54 for providing power to the crankcase 4, an oil tank 61 for providing lubricating oil to the crankcase 4, and a second motor 71 for providing power to transport the lubricating oil in the oil tank 61 to the crankcase 4 are also installed. To save space, the crankcase 4 and the oil tank 61 can be arranged vertically.

[0047] Further, a plurality of positioning components are arranged on the top of the flatbed truck 1 according to the equipment to be supported and transported, at least including a first positioning component 5, a second positioning component 6, a third positioning component 7, and a pipeline positioning member 8.

[0048] In some embodiments, as Figure 3 and Figure 4 shown, the hydraulic pump assembly 2 includes a first motor 54. The first motor 54 has a plurality of legs 541. A first positioning component 5 for the first motor 54 is arranged on the flatbed truck 1. The first positioning component 5 includes a support member 51 and an adjusting member 52. The legs 541 are arranged on the support member 51 and limited by the support member 51. The adjusting member 52 is used to adjust the position of the legs 541. Among them, the support member 51 restricts the position of the legs 541, and the adjusting member 52 can change the position of the legs 541, thereby changing the position of the first motor 54.

[0049] The support member 51 and the adjusting member 52 can be symmetrically arranged along the first motor 54, and they can cooperate on both sides of the first motor 54 to determine the position of the first motor 54.

[0050] Specifically, the support member 51 includes a bracket and a vertical plate 512. The vertical plate 512 is arranged on the outer side of the bracket. The leg 541 is arranged on the bracket 511 and abuts against the vertical plate 512. The adjusting member 52 passes through the vertical plate 512 and is arranged opposite to the leg 541. The bracket 511 is used to support the leg 541 of the first motor 54 and limit the movement of the leg 541 in the height direction of the hydraulic pump station. The vertical plate 512 is arranged on the outer side of the bracket 511 and the highest point of the vertical plate 512 is higher than the lowest point of the leg 541 to limit the movement of the leg 541. One end of the adjusting member 52 faces the leg 541. By adjusting the distance that the adjusting member 52 extends into the vertical plate 512, the position of the leg 541 can be adjusted, and thus the position of the first motor 54 on the flatbed truck 1 can be changed. Exemplarily, the adjusting member 52 is a screw.

[0051] In some embodiments, a guiding member 53 is arranged on the outer side of the vertical plate 512, and the adjusting member 52 is threadedly connected to the guiding member 53. Exemplarily, the guiding member 53 is a nut, which plays a guiding role for the movement of the adjusting member 52. The guiding member 53 is threadedly connected to the adjusting member 52, and the adjusting member 52 is threadedly connected to the vertical plate 512, making the movement of the adjusting member 52 more stable. Exemplarily, a plurality of guiding members 53 are arranged along the adjusting member 52 in sequence to increase the guiding length of the guiding member 53 and further improve the guiding effect of the guiding member 53.

[0052] In some embodiments, the hydraulic pump assembly 2 includes an oil tank 61, and a second positioning assembly 6 for the oil tank 61 is arranged on the flatbed truck 1. The second positioning assembly 6 includes a plurality of positioning seats 62. An installation space for installing the oil tank 61 is formed between the plurality of positioning seats 62, and the positioning seats 62 are correspondingly arranged with the corners 611 of the oil tank 61. Exemplarily, four positioning seats 62 are arranged and form a rectangular structure, providing a positioning function for the installation of the oil tank 61.

[0053] In some embodiments, the hydraulic pump assembly 2 includes a second motor 71, and a third positioning assembly 7 for the second motor 71 is arranged on the flatbed truck 1. Among them, the third positioning assembly 7 includes a positioning frame 72 installed on the flatbed truck 1. The top of the positioning frame 72 is provided with a plurality of threaded holes for connecting with the second motor 71 to fix the second motor 71 on the flatbed truck 1. In order to strengthen the support stiffness of the positioning frame 72, at least one side of the positioning frame 72 is provided with a reinforcing rib.

[0054] In some embodiments, the first motor 54 and the second motor 71 are disposed near the ends of the flatbed truck 1, and the fuel tank 61 is disposed between the first motor 54 and the second motor 71. Since the first motor 54 and the second motor 71 are generally heavy, and they are disposed at positions corresponding to the jacks 31, i.e., the ends of the flatbed truck 1, the jacks 31 will provide greater supporting force for the first motor 54 and the second motor 71, ensuring the strength of the flatbed truck 1 and being beneficial to ensuring the safe operation of the hydraulic pump station.

[0055] In some embodiments, the first positioning assembly 5, the second positioning assembly 6, and the third positioning assembly 7 are sequentially disposed along the top of the flatbed truck 1. By rationally utilizing the space of the positioning assemblies of each device, the floor area of the flatbed truck 1 is minimized as much as possible, making the flatbed truck 1 more flexible when moving in the narrow space area underground in the mine.

[0056] In some embodiments, a plurality of pipeline positioning members 8 are provided on the flatbed truck 1, and the pipeline positioning members 8 are disposed along the edge of the flatbed truck 1. Among them, the pipeline positioning members 8 can be configured as structures that can be clamped with the pipelines. The pipelines connected between the devices are limited by the pipeline positioning members 8, and the pipelines in the hydraulic pump station will not be arranged in a disorderly manner. Moreover, the pipeline positioning members 8 are disposed along the edge of the flatbed truck 1, avoiding hindering the installation of the fuel tank 61, the second motor 71, the first motor 54, etc. on the flatbed truck 1.

[0057] The transfer process of this hydraulic pump station is as follows:

[0058] The hydraulic pump assembly 2 is pre-installed on the top of the flatbed truck 1. After the hydraulic pump station is transported to the working position by the wheels 11, the jacks 31 lift the entire hydraulic pump station, and the wheels 11 are kept in a suspended state; subsequently, wooden squares 9 are arranged between the flatbed truck 1 and the ground, and then the piston rods 312 of the jacks 31 are retracted, and the hydraulic pump station starts to work.
