Description

Technical Field

[0001] This utility model relates to a multi-pass block structure, specifically, to a hydraulic support inlet and return multi-pass block with a joint anti-loosening device. Background Technology

[0002] The inlet and return fluid multi-way block is a component connecting the main inlet and return fluid pipes of the hydraulic support in a fully mechanized coal mining face. With the development of fully mechanized coal mining technology, the flow and pressure requirements of the fluid supply system in the working face are increasing. Therefore, the demand for SKV-type clamp-on pipelines is increasing. The connector of the SKV-type hydraulic support inlet and return fluid multi-way block is a threaded connector. In actual use, on the one hand, due to high pressure impact and vibration, the threaded connector is prone to unthreading, which leads to leakage of the pipeline connector; on the other hand, due to the limited space at the connector, it is difficult to disassemble and repair the connector.

[0003] For example, the liquid inlet connector for a multi-hole block disclosed in Chinese utility model patent CN202322522753.6 involves welding after the connector thread on the multi-hole block is connected. Although this prevents the threads from coming off, it makes it difficult to disassemble the threads later.

[0004] For example, the novel multi-channel block and corresponding hydraulic support system disclosed in Chinese utility model patent CN201620958736.4 includes an inverted triangular main body. The main body has two return channels, two inlet channels and one spray channel arranged sequentially from top to bottom. All five channels are inverted V-shaped. The two ends of the channels are respectively located on the two sides of the main body, and each port is a quick-connect plug. A branch port is opened on the side wall of each channel. With such a multi-channel block structure layout, the space on the multi-channel block is limited, making it difficult to disassemble and repair the joints, and also difficult to install anti-reverse locking devices.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of the existing technology by providing a hydraulic support inlet and outlet multi-channel block with a joint anti-loosening device. The inter-bracket interface on the multi-channel block is arranged at an angle and an anti-retraction buckle plate is added to the inter-bracket joint, which facilitates the disassembly of the inter-bracket joint and prevents the inter-bracket joint from relapsing.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a multi-pass block and an anti-retraction buckle plate. The multi-pass block includes an inter-rack interface and a block mounting surface. The inter-rack interface is inclined in a direction away from the block mounting surface. An inter-rack joint is installed in the inter-rack interface by means of threaded engagement. The inter-rack joint is provided with an anti-retraction ring. The anti-retraction buckle plate is provided with an anti-retraction groove. The anti-retraction buckle plate is installed on the multi-pass block. The anti-retraction ring is embedded in the anti-retraction groove to restrict the rotation of the inter-rack joint.

[0008] Based on the above, the multi-pass block is provided with at least two inter-shelf passages, and each end of the inter-shelf passage is provided with an inter-shelf interface.

[0009] Based on the above, the two inter-rack interface ports at both ends of the inter-rack passage are respectively located on the first end face and the second end face of the multi-pass block, and the two anti-retraction buckles are respectively installed on the first end face and the second end face, and the anti-retraction buckles are provided with anti-retraction grooves consistent with the number of inter-rack passages.

[0010] Based on the above, the anti-reverse buckle plate includes two side wing plates, and the side wing plates of the anti-reverse buckle plate are bolted to the two side surfaces of the first end face and the two side surfaces of the second end face.

[0011] Based on the above, the anti-retraction groove is set as an edge groove.

[0012] Based on the above, the multi-pass block has the same number of rack-in passages as the inter-rack passages, and the rack-in passages are connected to the inter-rack passages one by one. Each rack-in passage has at least one port on the multi-pass block that serves as a rack-in interface.

[0013] Based on the above, two internal interfaces are provided at both ends of the internal passage.

[0014] Based on the above, the axis of the interface inside the frame is parallel to the mounting surface of the block.

[0015] Based on the above, the inter-shelf passage is V-shaped and symmetrical on the multi-passage block, and the axes of the interconnected inter-shelf passage and the intra-shelf passage are coplanar.

[0016] Based on the above, the anti-retraction ring is a regular hexagonal ring, and the anti-retraction groove is a corresponding groove shape that can be embedded in the anti-retraction ring.

[0017] This utility model has substantial features and progress compared to the prior art. Specifically, the inter-frame interfaces on the multi-pass block are arranged in a direction that is inclined away from the block mounting surface, which expands the space of the inter-frame interfaces, which is conducive to the disassembly of the inter-frame joints and also conducive to the installation of anti-return plates on the inter-frame joints to prevent the threaded joints from being disengaged due to high pressure impact and vibration on the multi-pass block.

[0018] Meanwhile, the anti-reverse fastener is installed on the first and second end faces of the inter-rack interface. The anti-reverse fastener is mounted on the multi-pass block via side wing plates, and the anti-reverse groove uses an edge groove, making the anti-reverse fastener structure compact, efficient, and easy to assemble and disassemble quickly without affecting the assembly and disassembly of the inter-rack joint. Furthermore, by setting symmetrical inter-rack and intra-rack passages, the overall structure of the multi-pass block can be further simplified, reducing the overall space occupied.

[0027] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0028] Example 1

[0029] like Figures 1-3 As shown, the hydraulic support inlet and outlet multi-channel block with anti-loosening device of this embodiment includes a multi-channel block body 10, a support inter-connection 20, and an anti-retraction buckle plate 30. The multi-channel block body 10 includes a support inter-connection 11 and a block mounting surface 13. The support inter-connection 11 is inclined in a direction away from the block mounting surface 13. Thus, when the multi-channel block body 10 is installed on the hydraulic support through the block mounting surface 13, the support inter-connection 11 is inclined. Compared with the support inter-connection 11 arranged parallel to the block mounting surface 13, the support inter-connection 11 of this application has a larger space for installing the connector (support inter-connection 20). This facilitates the disassembly and maintenance of the connector, and the anti-retraction buckle plate 30 can be added to the multi-channel block using this space.

[0030] Specifically, a rack-to-rack connector 20 is installed in the rack-to-rack interface 11 by means of threaded connection. The rack-to-rack connector 20 can be a snap-fit ​​connector of the SKV type. In this application, the rack-to-rack connector 20 is first installed into the rack-to-rack interface 11 of the multi-pass block 10 by means of threaded connection, and then an anti-retraction buckle plate 30 is installed on the multi-pass block 10 to perform anti-retraction buckle treatment on the rack-to-rack connector 20.

[0031] More specifically, the frame joint 20 is provided with an anti-retraction ring 21, and the anti-retraction buckle 30 is provided with an anti-retraction groove 31. When the anti-retraction buckle 30 is installed on the multi-pass block 10, the anti-retraction ring 21 is embedded in the anti-retraction groove 31. In this way, the frame joint 20 is prevented from being unhooked from the anti-retraction groove 31 by limiting the rotation of the frame joint 20.

[0032] In this embodiment, the inter-frame interface 11 is arranged on the multi-pass block 10 in a direction that is inclined away from the block mounting surface 13, which expands the space of the inter-frame interface 11, which is conducive to the disassembly of the inter-frame joint 20 and also conducive to the installation of anti-retraction buckle plate 30 on the inter-frame joint 20 to prevent the threaded joint of the inter-frame joint 20 from being re-engaged due to high pressure impact and vibration on the multi-pass block 10.

[0033] Example 2

[0034] Based on Embodiment 1, in this embodiment, the multi-channel block 10 has at least two inter-shelf passages, with an inter-shelf interface 11 at each end of the passage. Both inter-shelf interfaces 11 at the ends of the same passage are inclined to the mounting surface 13 of the block. The two inter-shelf interfaces 11 at the ends of the same passage serve as the liquid inlet and outlet for the inter-shelf conveying liquid, respectively. The multi-channel block 10 can have two inter-shelf passages, used for the inlet and outlet of hydraulic oil; it can also have three inter-shelf passages, with the third passage used for water flow; or it can have more than three inter-shelf passages, depending on actual needs.

[0035] Based on the above, the two inter-rack interfaces 11 at both ends of the inter-rack passage are located on the first end face 14 and the second end face 15 of the multi-pass block 10, respectively. The inter-rack interfaces 11 of the multiple inter-rack passages are all located on the first end face 14 and the second end face 15, respectively. In this way, by using two anti-retraction buckles 30 respectively installed on the first end face 14 and the second end face 15, and the anti-retraction buckles 30 are provided with anti-retraction grooves 31 that are the same as the number of inter-rack passages, all the inter-rack joints on the multi-pass block 10 can be restricted from rotating by the two anti-retraction buckles 30, thereby reducing the number of anti-retraction buckles 30 and simplifying the overall structure.

[0036] Based on the above, the orientation of the inter-frame interface 11 on the first end face 14 is consistent, and the orientation of the inter-frame interface 11 on the second end face 15 is consistent, so that the anti-retraction buckle plate 30 can be made of a flat plate, simplifying the structure of the anti-retraction buckle plate 30.

[0037] Based on the above, the anti-reverse buckle plate 30 includes two side wing plates. The wing plates of the anti-reverse buckle plate 30 are bolted to the two side sides of the first end face 14 and the two side sides of the second end face 15, thereby reducing the space occupied by the anti-reverse buckle plate 30.

[0038] Based on the above, the anti-retraction ring 21 adopts a regular hexagonal ring, and the anti-retraction groove 31 adopts a groove shape that can be embedded in the anti-retraction ring 21. This can restrict the rotation of the frame joint 20 on the one hand, and the anti-retraction ring 21 can be used to tighten or loosen the frame joint 20 on the other hand. Of course, the anti-retraction ring 21 and the anti-retraction groove 31 can also adopt other shapes that can restrict the rotation of the frame joint 20, such as other polygonal or plum blossom shapes.

[0039] Based on the above, the anti-retraction groove 31 on the anti-retraction buckle 30 is an edge groove located at the edge of the anti-retraction buckle 30. The edge groove has a notch that communicates with the outside through the edge of the anti-retraction buckle 30. The anti-retraction groove 31 can be installed radially around the periphery of the polygonal groove using this notch. The edge groove can be used to quickly install and remove the anti-retraction buckle 30, and the anti-retraction buckle 30 will not affect the installation and removal of the frame connection 20.

[0040] In this embodiment, the anti-retraction buckle 30 has a compact, efficient structure and is easy to assemble and disassemble quickly, without affecting the assembly and disassembly of the rack joint 20.

[0041] Example 3

[0042] Based on Embodiment 1 or Embodiment 2, in this embodiment, the multi-pass block 10 is provided with the same number of rack-in passages as the inter-rack passages, and the rack-in passages are connected to the inter-rack passages one by one. The rack-in passages are provided with at least one port on the multi-pass block 10 as rack-in interface 12.

[0043] Based on the above, two internal interfaces 12 are provided at both ends of the internal passage; further, the axis of the internal interface 12 is parallel to the block mounting surface 13; even further, the inter-shelf passage is V-shaped and symmetrical on the multi-pass block 10, and the axes of the connected inter-shelf passage and the internal passage are coplanar, so that the multi-pass block 10 is symmetrical on both sides, which can further simplify the overall structure of the multi-pass block 10 and reduce the overall space occupied.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
