[0065] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0066] like Figures 1 to 7As shown, an embodiment of the present invention provides a hydraulic support, which includes: a frame body 10, a pressure regulating system and a cleaning assembly 30. The frame body 10 includes a base 11, a top beam 12 and a plurality of hydraulic struts 13, the base 11 is located below the top beam 12, and the plurality of hydraulic struts 13 are movably arranged between the base 11 and the top beam 12, and the hydraulic struts 13 are used to drive the top beam 12 to move up and down relative to the base 11. The pressure regulating system is located between the base 11 and the top beam 12. The pressure regulating system includes a main pipeline and multiple branch pipelines. One end of the main pipeline is connected to the oil tank, and the other end of the main pipeline is respectively connected to the multiple branch pipelines. The multiple branch pipelines are respectively arranged in a one-to-one correspondence with the multiple hydraulic pillars 13. A first valve body 21 is arranged on the main pipeline, and a second valve body 22 is arranged on the branch pipeline. The second valve body 22 has multiple, and the multiple second valve bodies 22 are arranged in a one-to-one correspondence with the multiple branch pipelines; multiple cleaning components 30 are arranged on the second valve body 22, and the cleaning components 30 are used to clean the second valve body 22. The multiple cleaning components 30 are arranged in a one-to-one correspondence with the multiple second valve bodies 22.

[0067] By applying the technical solution of the present invention, the pressure system includes a first valve body 21 and a plurality of second valve bodies 22. The plurality of second valve bodies 22 can control the flow in the plurality of branch pipelines respectively, thereby driving and controlling the plurality of hydraulic pillars 13. The first valve body 21 can control the flow in the main pipeline, thereby controlling each hydraulic pillar 13 simultaneously. In this way, when one of the second valve bodies 22 is damaged and cannot control the flow in the branch pipeline, and one of the second valve bodies 22 needs to be replaced or repaired, the flow in the main pipeline and each branch pipeline can be controlled by the first valve body 21, which can play a role in regulating the hydraulic pillar 13, ensuring the normal support of the plurality of hydraulic pillars 13, reducing the impact of the second valve body 22 on the support work of the hydraulic support when it is damaged, and reducing the possibility of collapse caused by uneven force on the top plate during the replacement of the hydraulic support. At the same time, the second valve body 22 can be cleaned by the cleaning component 30 to prevent dust and impurities from clogging the second valve body and causing the hydraulic pillar 13 to fail to adjust, thereby ensuring the working efficiency of the hydraulic system.

[0068] Specifically, there is no limitation on the specific structures of the first valve body 21 and the second valve body 22 , which can be configured as a throttle valve or a relief valve.

[0069] like Figure 1 and Figure 2As shown, the hydraulic support also includes a control cabinet 40, which is arranged on the base 11. A controller is arranged inside the control cabinet 40. The controller is respectively connected to the first valve body 21 and the plurality of second valve bodies 22 by driving, and the opening or closing of the first valve body 21 and the plurality of second valve bodies 22 can be controlled by the controller. Through the above arrangement, the control of the hydraulic support 13 is more intelligent, and the pressure of the hydraulic support 13 can be accurately adjusted according to the working requirements. It is suitable for mining operations with a high degree of automation, and improves work efficiency and safety. Compared with the manual control of the opening and closing of the valve by the staff, the setting of the controller can not only improve the response speed of the hydraulic support, but also reduce manual intervention and reduce the operation risk. In addition, the control cabinet 40 can also protect the controller to prevent the controller from being damaged by coal blocks or falling rocks splashing from the outside.

[0070] Further, the output end of the controller is electrically connected to the first output module and the second output module, the output end of the first output module is electrically connected to the first valve body control module, the output end of the first valve body control module is electrically connected to the first receiving module, the first receiving module is electrically connected to the input end of the first valve body 21, the output end of the second output module is electrically connected to the second valve body control module, the output end of the second valve body control module is electrically connected to the second receiving module, and the second receiving module is electrically connected to the input end of the second valve body 22. Through the above settings, the controller can control the first valve body 21 and the second valve body 22 separately, thereby facilitating the control of the hydraulic support 13.

[0071] Specifically, a second valve body processor is provided on the inner wall of the second valve body 22, the input end of the second valve body processor is electrically connected to the information input module, the output end of the second valve body processor is electrically connected to the information processing module, and the output end of the information processing module is electrically connected to the second valve body control module; by setting up a control system for the second valve body 22, the second valve body 22 can be auxiliary controlled so that the second valve body 22 can be used alone.

[0072] By setting the above structure, when in use, under the action of the second output module inside the control cabinet 40, in cooperation with the second valve body control module, the second receiving module transmits information to the second valve body 22, and then controls the second valve body 22 to control the hydraulic support 13. When the second valve body 22 fails or is damaged, at this time, under the action of the first output module, in cooperation with the first valve body control module, the information can be transmitted to the first receiving module, and then the first valve body 21 can be controlled to open, and then the hydraulic support 13 can be controlled to adjust the pressure. Alternatively, the second valve body 22 can be controlled separately, and the information can be manually input and transmitted to the second valve body processor under the action of the information input module on the second valve body 22, and then cooperated with the second valve body control module for separate control. The flexibility and applicability of the control of the hydraulic support 13 are improved.

[0073] The hydraulic support further includes a rotating assembly 50, which is disposed between the hydraulic support 13 and the second valve body 22.

This design allows the position of the second valve body 22 to be adjusted as needed, which can avoid interference between the second valve body 22 and other components, thereby improving the space utilization of the hydraulic support and the flexibility of component arrangement.

[0074] like Figure 4 As shown, the rotating assembly 50 includes: an annular block 51, a rotating frame 52 and a locking structure. The annular block 51 is sleeved on the fixed end of the hydraulic support 13, and the fixed end is located on the side of the hydraulic support 13 close to the base 11. The rotating frame 52 is sleeved on the outer periphery of the annular block 51, and the second valve body 22 is arranged on the outer side wall of the rotating frame 52. The rotating frame 52 can rotate relative to the annular block 51 along the circumferential direction of the annular block 51 to adjust the relative position of the second valve body 22 and the hydraulic support 13 in the circumferential direction of the hydraulic support 13. The locking structure is arranged between the annular block 51 and the rotating frame 52, and the locking structure is used to fix the relative position of the rotating frame 52 and the annular block 51. Through the cooperation of the annular block 51 and the rotating frame 52, the position adjustment of the second valve body 22 is realized, and the stability of the second valve body 22 after adjustment is ensured by the locking structure, thereby improving the adaptability and maintenance efficiency of the hydraulic support.

[0076] Among them, a guide groove 511 is arranged in a circumferential ring along the side of the annular block 51 facing the rotating frame 52, and a guide protrusion 522 is correspondingly arranged on the side of the rotating frame 52 facing the annular block 51. The guide protrusion 522 is located in the guide groove 511. Through the above structure, the rotation direction of the rotating frame 52 relative to the annular block 51 can be guided, thereby improving the adjustment accuracy of the rotating component 50.

[0088] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0089] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
