Description

Technical Field

[0001] This utility model relates to the field of hydraulic support hose structure, specifically, to a hydraulic hose arrangement structure for a front beam support mechanism. Background Technology

[0002] For example, the hydraulic support side jack hose connection mechanism disclosed in Chinese utility model patent CN202023264321.2 includes a front beam, a telescopic beam, a telescopic beam jack, a side support, a side jack, and a fluid supply pipeline corresponding to the side jack. The fluid supply pipeline includes a multi-way block and a first fluid supply hose and a second fluid supply hose connected by the multi-way block. The multi-way block is installed below the front part of the front beam. The fluid supply ports of the multi-way block and the side jack are located on opposite sides of the side jack cylinder. The first fluid supply hose starts from the outlet hole of the front beam and connects directly to the multi-way block. The second fluid supply hose starts from the multi-way block, passes around the rear end of the side jack, and connects to the side jack's fluid supply port, forming a U-shaped bend. This hydraulic support side jack hose connection mechanism has the advantages of simple structure, always fitting snugly against the front beam, neat hose layout, and low risk of accidental contact.

[0003] However, this scheme, which places the fluid supply lines on both sides of the support jack, requires sufficient lateral space to arrange the fluid supply lines in order to complete the industrial pipeline layout during the telescopic beam movement. With the recent trend towards higher extraction heights and greater working resistance in hydraulic supports, the cylinder diameter of hydraulic supports has increased significantly, leading to increasingly limited space in the support structure. This is especially true in the front beam support mechanism, where the support jacks, telescopic jacks, and side-push jacks are arranged very compactly in the lateral space on the front beam. Conventional hydraulic hose arrangements for support jacks are difficult to implement due to insufficient space. Furthermore, the hydraulic hoses need to be long enough to accommodate the dimensions after the support extends; any excess hose length has no place to be fixed or restrained, posing a risk of abnormal wear and damage from compression during use.

[0004] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a hydraulic hose arrangement structure for the front beam support mechanism. The inlet and return pipes can be arranged at the bottom of the front beam, and the allowance of the inlet and return pipes is constrained by the first perforation and the arc-shaped bend, so as to avoid squeezing or abrading the inlet and return pipes when the telescopic beam extends or retracts.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes an inlet and outlet liquid pipe, which passes through a first perforation at the bottom end of the front beam and is fixed to the rear end of the support plate on the telescopic beam. The first perforation faces the support plate, and the inlet and outlet liquid pipe is arranged in an arc-shaped bend on the side of the first perforation away from the support plate. The opening of the arc-shaped bend faces the support plate, and the first perforation is located in the middle section of the telescopic stroke of the rear end of the support plate. When the inlet and outlet liquid pipe extends and retracts with the rear end of the support plate, its body extends and retracts within the first perforation.

[0007] This application does not require occupying the lateral space of the front beam to arrange the inlet and return liquid pipes. The inlet and return liquid pipes can be arranged at the bottom of the front beam, such as below the telescopic beam jack, the side push jack, and the first-level side protection jack. Furthermore, this application constrains the margin of the inlet and return liquid pipes through the first perforation and the arc-shaped bend, so as to avoid squeezing or abrading the inlet and return liquid pipes when the telescopic beam extends or retracts.

[0008] Based on the above, the bottom end of the front beam is also provided with a second through hole and a third through hole, the inlet and outlet pipes pass through the second through hole and the third through hole, the two ends of the arc-shaped bend pass through the first through hole and the second through hole respectively, and the third through hole is adjacent to the second through hole and the two are perpendicular to each other.

[0009] The inlet and outlet pipes are constrained by adjacent and perpendicular third and second perforations, allowing them to have a certain amount of expansion and contraction rather than being completely constrained. This further prevents the expansion beam from squeezing or wearing the inlet and outlet pipes during expansion and contraction.

[0010] Based on the above, the third perforation is located on the rear side of the tray.

[0011] The third perforation located on the rear side of the support plate allows for a longer arc-shaped bend, providing a longer margin for the inlet and outlet pipes and further preventing the inlet and outlet pipes from being squeezed or worn during the extension and retraction of the telescopic beam.

[0012] Based on the above, the inlet and outlet pipe includes a secondary side support branch pipe, which is laid from back to front on the side wall of the pallet to connect to the secondary side support jack.

[0013] By laying the secondary support branch pipes from back to front on the side wall of the support plate, when the telescopic beam extends or retracts, a portion of the secondary support branch pipes fixed on the support plate will extend or retract along with the support plate, which can prevent the telescopic beam from squeezing or abrading the inlet and outlet pipes when it extends or retracts.

[0014] Based on the above, a multi-port block is installed at the rear end of the tray, the multi-port block connects the front and rear sections of the inlet and return liquid pipes, and the inlet and return liquid pipes are fixed to the rear end of the tray in a segmented manner by connecting the multi-port block.

[0015] The porous block allows the inlet and outlet pipes to be securely fixed to the rear end of the tray.

[0016] Based on the above, the interfaces at both ends of the multi-channel block face the front and rear ends of the tray, respectively. The front section of the inlet and outlet liquid pipe is connected from the front end of the multi-channel block, and the rear section of the inlet and outlet liquid pipe is connected from the rear end of the multi-channel block.

[0017] By connecting the inlet and return liquid pipes to the front end of the multi-port block, the bending of the inlet and return liquid pipes due to their extension and retraction strokes can be avoided, thus preventing them from occupying too much space at the rear end of the tray.

[0018] Based on the above, the secondary support branch pipe includes an inlet pipe and a return pipe, and the inlet pipe and return pipe of the secondary support branch pipe are respectively laid from back to front from both sides of the side wall of the support plate.

[0019] By separating the inlet and return pipes of the secondary support branch pipe, the space occupied by the inlet and return pipes is further reduced.

[0020] Based on the above, a hanging block is provided at the rear end of the pallet, and the multi-channel block is installed on the hanging block.

[0021] The multi-channel block can be securely mounted on the tray using a hanging block.

[0022] Based on the above, the side wall of the pallet and the surface of the primary side support plate are provided with fixing rings and pipe clamps. The secondary side support pipe is fixed at the rear end of the pallet by the fixing rings and at the front end of the primary side support plate by the fixing rings. The secondary side support pipe passes through the pipe clamps on both sides of the hinge axis between the primary side support plate and the telescopic beam, so that the secondary side support pipe can extend and retract within the pipe clamps when the primary side support plate rotates.

[0023] The inlet and outlet pipes can be effectively constrained by the fixing ring. By setting pipe clamps on both sides of the hinge shaft of the first-stage side guard plate and the telescopic beam, the inlet and outlet pipes can extend and retract within the pipe clamps, which can prevent the inlet and outlet pipes from being squeezed or worn when the first-stage side guard plate rotates.

[0024] Based on the above, side wing plates are provided on both sides of the pallet, and the secondary side support pipe is located between the side wing plates and the side walls of the pallet.

[0025] The side wing plates provide lateral protection for the inlet and outlet pipes, preventing them from being squeezed or worn during the extension and retraction of the telescopic beam. Attached Figure Description

Detailed Implementation

[0033] The technical solution of this utility model will be further described in detail below through specific embodiments. Example 1

[0034] like Figures 1-6 As shown, the hydraulic hose arrangement structure of the front beam support mechanism in this embodiment includes an inlet and return pipe 1, which is arranged on the front beam 21 of the hydraulic support.

[0035] In this embodiment, the front beam support mechanism of the hydraulic support may include: front beam 21 (or top beam), telescopic beam 22, support plate 2, primary support plate 23 and secondary support plate 24; the driving jacks in the front beam support mechanism may include: telescopic beam jack 31, primary support jack 32 and secondary support jack 33; side push jacks may also be provided on both sides of the support plate 2.

[0036] Specifically, a telescopic beam 22 is slidably mounted on the front beam 21, and a telescopic beam jack 31 for driving the telescopic beam 22 to slide is installed on the front beam 21. A support plate 2 is provided on the telescopic beam 22, and a primary side guard plate 23 is hinged to the telescopic beam 22. A primary side guard jack 32 for driving the primary side guard plate 23 to rotate on the telescopic beam 22 is installed on the support plate 2. A secondary side guard plate 24 is hinged to the primary side guard plate 23, and a secondary side guard jack 33 for driving the secondary side guard plate 24 to rotate on the primary side guard plate 23 is installed on the primary side guard plate 23.

[0037] In this embodiment, the inlet and outlet pipe 1 passes through the first perforation 101 at the bottom of the front beam 21 and is fixed to the rear end of the support plate 2 on the telescopic beam 22. The first perforation 101 faces the support plate 2. The inlet and outlet pipe 1 is located in an arc-shaped bend on the side of the first perforation 101 away from the support plate 2. The opening of the arc-shaped bend faces the support plate 2. The first perforation 101 is located in the middle of the telescopic stroke of the rear end of the support plate 2. When the inlet and outlet pipe 1 extends and retracts with the rear end of the support plate 2, its pipe body extends and retracts within the first perforation 101.

[0038] It is worth noting that the directional orientations of the relevant accessories in this application, such as "front end" and "rear end", are based on the front-to-back direction of the hydraulic support. For example, the front end of the pallet 2 faces the front end of the hydraulic support, and the rear end of the pallet 2 faces the rear end of the hydraulic support.

[0039] It is worth noting that "bottom end of front beam 21" refers to the bottom end of front beam 21 when the hydraulic support is in normal support condition, such as... Figure 1 This is the upward view of the front beam 21, looking towards the bottom of the front beam 21.

[0040] When the support plate 2 extends and retracts on the front beam 2 along with the telescopic beam 22, a portion of the inlet and outlet pipe 1, which is fixed on the support plate 2, will move relative to the rear end of the support plate 2 on the front beam 2. A portion of the inlet and outlet pipe 1, which passes through the first through hole 101, will extend and retract within the first through hole 101. A portion of the inlet and outlet pipe 1 forms an arc-shaped bend on one side of the first through hole 101. When the inlet and outlet pipe 1 extends and retracts within the first through hole 101, the arc-shaped bend will increase or decrease. When the rear end of the support plate 2 slides towards the middle of its extension and retraction stroke, the arc-shaped bend increases, and vice versa.

[0041] The arc-shaped bend is similar to a C-shape. The arc-shaped bend is used to store the remaining amount of the inlet and outlet pipe 1. The inlet and outlet pipe 1 expands or contracts within the first perforation 101 to increase or decrease the arc-shaped bend. The increase or decrease will not destroy the arc-shaped bend. Therefore, the inlet and outlet pipe 1 with the arc-shaped bend can always be within the area defined by the arc-shaped bend to prevent the inlet and outlet pipe from being worn or squeezed.

[0042] In this embodiment, there is no need to occupy the lateral space of the front beam 1 to arrange the inlet and return pipes 1. The inlet and return pipes 1 can be arranged at the bottom of the front beam 21, such as below the telescopic beam jack 31, the side push jack and the first-level side protection jack 32. The remaining space of the inlet and return pipes 1 is constrained by the first perforation 101 and the arc-shaped bend to prevent the telescopic beam 22 from squeezing or wearing the inlet and return pipes 1 when it extends or retracts. Example 2

[0043] Based on Embodiment 1, in this embodiment, the bottom end of the front beam 21 is also provided with a second through hole 102 and a third through hole 103. The inlet and outlet pipe 1 passes through the second through hole 102 and the third through hole 103. The two ends of the arc-shaped bend pass through the first through hole 101 and the second through hole 102 respectively. The third through hole 103 is adjacent to the second through hole 102 and the two are perpendicular. The inlet and outlet pipe 1 is constrained by the adjacent and perpendicular third through hole 103 and the second through hole 102, so that the inlet and outlet pipe 1 can have a certain amount of expansion and contraction between the two rather than being completely constrained. This can prevent the support plate 2 from squeezing or wearing the inlet and outlet pipe 1 when it expands and contracts with the telescopic beam 22.

[0044] In this embodiment, the inlet and outlet pipe 1 is on the front beam 21, passing through the third perforation 103, the second perforation 102 and the first perforation 101 in sequence, and is then fixed to the rear end of the support plate 2.

[0045] Furthermore, the third perforation 103 is located on the rear side of the support plate 2, which allows for a longer arc-shaped bend, giving the inlet and outlet pipes 1 a longer margin. Example 3

[0046] Based on Embodiment 1 or Embodiment 2, in this embodiment, the inlet and outlet pipe 1 includes a primary side support pipe 11 and a secondary side support pipe 12. The primary side support pipe 11 is directly connected from the rear end of the support plate 2 to the primary side support jack 32 on the support plate 2. The secondary side support pipe 12 is laid from back to front on the side wall of the support plate 2 to connect to the secondary side support jack 33.

[0047] The secondary support branch pipe 12 is laid from back to front on the side wall of the support plate 2. When the telescopic beam 22 extends and retracts, a portion of the secondary support branch pipe 12 fixed on the support plate 2 will extend and retract along with the extension and retraction of the support plate 2, which can prevent the telescopic beam 22 from squeezing or abrading the inlet and outlet pipes 1 when it extends and retracts.

[0048] Furthermore, the secondary support branch pipe 12 includes an inlet pipe and a return pipe, with the inlet and return pipes of the secondary support branch pipe 12 being laid from back to front on both sides of the support plate 2. By arranging the inlet and return pipes of the secondary support branch pipe 12 separately, the space occupied by the inlet and return pipes 1 is further reduced.

[0049] The primary support jack 32 and the secondary support jack 33 can be installed in pairs. The inlet and return pipes of the primary support branch pipe 11 can be connected to the two primary support jacks 32 near the two primary support jacks 32 respectively through three-way valves. The inlet and return pipes of the secondary support branch pipe 12 can be connected to the two secondary support jacks 33 near the two secondary support jacks 33 respectively through three-way valves.

[0050] Furthermore, side wing plates 7 are provided on both sides of the support plate 2, and secondary side protection branch pipes 12 are located between the side wing plates 7 and the side walls of the support plate 2. The side wing plates 7 can provide lateral protection for the inlet and return pipes 1, preventing the telescopic beam 22 from squeezing or abrading the inlet and return pipes 1 when it extends or retracts. Example 4

[0051] Based on Embodiment 1 or Embodiment 3, in this embodiment, a multi-port block 3 is installed at the rear end of the tray 2. The multi-port block 3 connects the front and rear sections of the inlet and return liquid pipe 1, and the inlet and return liquid pipe 1 is fixed to the rear end of the tray 2 by segmenting the multi-port block 3. The multi-port block 3 enables the inlet and return liquid pipe 1 to be firmly fixed to the rear end of the tray 2.

[0052] The inlet and return pipes of the secondary support branch pipe 12 can be arranged from both sides of the multi-port block 3 to both sides of the support plate 2 through L-shaped interfaces. The inlet and return pipes of the primary support branch pipe 11 can be connected to the primary support jack 32 from back to front through L-shaped connectors, bypassing the multi-port block 3.

[0053] In this application, the front and rear sections of the inlet and return pipe 1 are determined based on their orientation in connecting the pump station and the jack. The front section of the inlet and return pipe 1 refers to the section connected to the hydraulic pump station, and the rear section of the inlet and return pipe 1 refers to the section connected to the jack.

[0054] Furthermore, the interfaces at both ends of the multi-port block 3 face the front and rear ends of the tray 2, respectively. The front end of the multi-port block 3 faces the front end of the hydraulic support, and the rear end of the multi-port block 3 faces the rear end of the hydraulic support. The front section of the inlet and return pipe 1 is connected from the front end of the multi-port block 3, and the rear section of the inlet and return pipe 1 is connected from the rear end of the multi-port block 3. Because the space at the rear end of the tray 2 is more confined than the space at its front end, connecting the front section of the inlet and return pipe 1 from the front end of the multi-port block 3 avoids the inlet and return pipe 1 from bending due to its extension stroke and occupying too much space at the rear end of the tray 2.

[0055] Furthermore, the rear end of the pallet 2 is provided with a hanging block 4, and the multi-pass block 3 is installed on the hanging block 4; the hanging block 4 can be fixed to the rear end of the pallet 2 by welding, and the multi-pass block 3 can be installed on the hanging block 4 by bolting. Example 5

[0056] Based on Embodiment 3 or Embodiment 4, in this embodiment, fixing rings 5 ​​and pipe clamps 6 are provided on the side wall of the support plate 2 and the surface of the primary side support plate 23. The secondary side support branch pipe 12 is fixed at the rear end of the support plate 2 by the fixing rings 5 ​​and at the front end of the primary side support plate 23 by the fixing rings 5. The secondary side support branch pipe 12 passes through the pipe clamps 6 on both sides of the hinge axis of the primary side support plate 23 and the telescopic beam 22, so that the secondary side support branch pipe 12 can extend and retract within the pipe clamps 6 when the primary side support plate 23 rotates. The fixing rings 5 ​​can effectively constrain the inlet and return pipes 1. By setting the pipe clamps 6 on both sides of the hinge axis of the primary side support plate 23 and the telescopic beam 22, the inlet and return pipes 1 can extend and retract within the pipe clamps 6, which can prevent the inlet and return pipes 1 from being squeezed or worn when the primary side support plate rotates.

[0057] 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.
