[0052] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0053] In the prior art, during the operation of the hydraulic support, a stopper is provided on one side of the pin shaft to prevent the pin shaft from falling off. When the working resistance of the hydraulic support becomes larger and larger, the weight of the whole machine also increases continuously. The pin shaft in the hydraulic support, as the main force-bearing element, bears a large load force. When the main reinforcement structure strength of the hydraulic support is insufficient, the main reinforcement cannot withstand the function of the pin shaft extrusion and shearing. When the main reinforcement is subjected to repeated impact, it is easy to be damaged, which shortens the service life of the hydraulic support, increases the maintenance cost of the hydraulic support, and brings safety hazards to the use of the hydraulic support and other adverse effects.

[0054] In order to solve at least one of the technical problems existing in the prior art or related technology, the inventor of the utility model has made creative improvements to the structure of the pin stopper in order to avoid damage to the main ribs during the use of the hydraulic support, effectively extend the service life of the hydraulic support, and reduce the maintenance cost of the hydraulic support. The pin stopper 1 disclosed in the utility model has a mounting rib 13 arranged on the bearing plate 11, and forms a mounting cavity 14 with the bearing plate 11. The mounting cavity 14 is used to install the pin stopper plate 15. There is no need to form a space for accommodating the pin stopper plate 15 by opening a groove on the bearing plate 11, thereby ensuring the structural strength of the bearing plate 11. On the basis of preventing the pin shaft 22 from moving in the axial direction, it is sufficient to withstand the force of extrusion and shearing from the pin shaft 22, and will not cause damage to the main ribs 21, thereby extending the service life of the hydraulic support 2 and reducing the maintenance cost of the hydraulic support 2. At the same time, the pin stopper 1 proposed in the utility model integrates the two functions of pin stopper and bearing, has a simple structure, reduces the difficulty of installation and processing, and reduces production costs.

[0055] The following describes the pin holder 1 and the hydraulic support 2 according to some embodiments of the present invention with reference to the accompanying drawings.

[0056] See also Figure 1 , Figure 2 and Figure 3The utility model provides a pin stopper 1 in one embodiment, which is used for a hydraulic support 2. The hydraulic support 2 includes a main rib 21 and a pin shaft 22 passing through the main rib 21. The pin stopper 1 includes a bearing plate 11, a mounting rib 13 and a pin stopper plate 15, wherein the bearing plate 11 includes a first wall surface 111 and a second wall surface 112 opposite to each other, and the first wall surface 111 is used to contact the main rib 21. A through hole 12 is provided through the first wall surface 111 and the second wall surface 112, and the through hole 12 is used to accommodate the pin shaft 22. The mounting rib 13 is provided on the second wall surface 112, and at least two mounting cavities 14 are provided between the mounting rib 13 and the second wall surface 112, and at least two mounting cavities 14 are distributed on both sides of the through hole 12. A portion of the pin stopper plate 15 is provided through the mounting cavity 14 and covers the through hole 12, so as to limit the axial movement of the pin shaft 22.

[0057] In this embodiment, the pin stopper 1 includes a bearing plate 11, a mounting rib 13 and a pin stopper plate 15. The bearing plate 11 is a plate-like structure, and the bearing plate 11 includes a first wall surface 111 and a second wall surface 112 opposite to each other. When the pin stopper 1 is installed at the main rib 21 of the hydraulic support 2, the first wall surface 111 of the bearing plate 11 contacts the main rib 21, that is, the first wall surface 111 is attached to the main rib 21. A through hole 12 is also provided on the bearing plate 11, and the through hole 12 is arranged on the bearing plate 11 through and is used to accommodate the pin shaft 22. The mounting rib 13 is arranged on the second wall surface 112 of the bearing plate 11, that is, the mounting rib 13 is arranged on the bearing plate 11 away from the main rib 21. There is an installation cavity 14 between the installation rib 13 and the bearing plate 11, and the installation cavity 14 is used to accommodate the pin stopper plate 15. Specifically, the number of the installation cavities 14 is at least two, and at least two installation cavities 14 are distributed on both sides of the through hole 12. After the pin stop plate 15 passes through at least two installation cavities 14, it can cover the through hole 12 located between the at least two installation cavities 14, thereby preventing the pin shaft 22 from falling off from the main rib 21.

[0058] In a possible embodiment, the mounting rib 13 may be an annular rib, which is disposed on the second wall surface 112 of the carrier plate 11 around the through hole 12. At least two grooves are disposed on the annular rib, so that at least two mounting cavities 14 are formed between the annular rib and the carrier plate 11, and the at least two mounting cavities 14 are respectively located on both sides of the through hole 12.

[0059] The stop pin seat 1 disclosed by the utility model has a mounting rib 13 disposed on the bearing plate 11, and forms a mounting cavity 14 with the bearing plate 11. The mounting cavity 14 is used to install the stop pin plate 15, and there is no need to form a space for accommodating the stop pin plate 15 by opening a groove on the bearing plate 11, thereby ensuring the structural strength of the bearing plate 11. On the basis of preventing the pin shaft 22 from moving along the axial direction, it is sufficient to withstand the force of extrusion and shearing from the pin shaft 22, prevent damage to the main rib 21, extend the service life of the hydraulic support 2, and reduce the maintenance cost of the hydraulic support 2. At the same time, the stop pin seat 1 proposed by the utility model integrates the two functions of stop pin and bearing, has a simple structure, reduces the difficulty of installation and processing, and reduces the production cost.

[0060] See also Figure 1 , Figure 2 and Figure 4 In some possible embodiments, the mounting rib 13 includes a first mounting rib 131 and a second mounting rib 132, and a first mounting cavity 141 is provided between the first mounting rib 131 and the second wall surface 112. A second mounting cavity 142 is provided between the second mounting rib 132 and the second wall surface 112, and the first mounting rib 131 and the second mounting rib 132 are distributed on both sides of the through hole 12.

[0061] In this embodiment, the mounting rib 13 includes a first mounting rib 131 and a second mounting rib 132 that are independent of each other. The first mounting rib 131 and the second mounting rib 132 are spaced apart on the supporting plate 11. A first mounting cavity 141 is provided between the first mounting rib 131 and the supporting plate 11. A second mounting cavity 142 is provided between the second mounting rib 132 and the supporting plate 11. At least two mounting cavities 14 include the first mounting cavity 141 and the second mounting cavity 142.

[0062] The first mounting rib 131 and the second mounting rib 132 are distributed on both sides of the through hole 12, that is, the first mounting cavity 141 and the second mounting cavity 142 are distributed on both sides of the through hole 12. It should be noted that the first mounting cavity 141 and the second mounting cavity 142 can be distributed on the left and right sides of the through hole 12, or on the upper and lower sides of the through hole 12, and those skilled in the art can make appropriate choices according to actual conditions.

[0063] When the pin stop plate 15 is installed on the supporting plate 11, the pin stop plate 15 passes through one of the first mounting cavity 141 and the second mounting cavity 142, and then covers the through hole 12, and then passes through the other of the first mounting cavity 141 and the second mounting cavity 142 to complete the positioning and installation of the pin stop plate 15, thereby preventing the pin shaft 22 from falling off from the through hole 12.

[0064] In this embodiment, the first mounting rib 131 and the second mounting rib 132 are respectively arranged on the supporting plate 11 to form the first mounting cavity 141 and the second mounting cavity 142. The first mounting rib 131 and the second mounting rib 132 only need to be arranged at necessary positions, which can save materials to the greatest extent and reduce production costs.

[0065] In a possible embodiment, the supporting plate 11 includes an outer edge and an inner edge enclosing the through hole 12 , wherein the first mounting rib 131 and the second mounting rib 132 are arranged closer to the inner edge than the outer edge.

[0066] In this embodiment, the outer contour of the bearing plate 11 constitutes its outer edge, and the inner contour of the bearing plate 11 constitutes its inner contour. In other words, the through hole 12 on the bearing plate 11 is formed by the inner edge thereof. Compared with the outer edge, the first mounting rib 131 and the second mounting rib 132 are both arranged close to the inner edge, that is, the first mounting rib 131 and the second mounting rib 132 are both arranged close to the pin 22, so that during the axial movement of the pin 22, the part of the bearing plate 11 close to the pin 22 will be subjected to a greater impact force. The arrangement of the first mounting rib 131 and the second mounting rib 132 can not only quickly buffer the force at the pin stopper plate 15, but also enhance the structural stability of the bearing plate 11. The ingenious arrangement of the positions of the first mounting rib 131 and the second mounting rib 132 can simultaneously achieve the effect of buffering the force and enhancing the structural strength of the bearing plate 11.

[0067] In a possible embodiment, the first mounting rib 131 and the second mounting rib 132 have the same structure, which reduces the difficulty of processing.

[0068] See also Figure 5 Optionally, the first mounting rib 131 is a U-shaped rib. Optionally, the second mounting rib 132 is a U-shaped rib.

[0069] In this embodiment, the first mounting rib 131 and / or the second mounting rib 132 may be U-shaped ribs, which have a simple structure. The U-shaped ribs themselves can enclose a cavity and be disposed on the bearing plate 11 .

[0070] See also Figure 3 In some possible embodiments, the thickness of the carrying plate 11 is greater than the thickness of the pin stop plate 15 .

[0071] In this embodiment, the thickness of the bearing plate 11 is greater than that of the pin stop plate 15. Since the bearing plate 11 is used to withstand the extrusion and shear forces from the pin shaft 22, providing a thicker bearing plate 11 is beneficial to preventing the force at the pin shaft 22 from being transmitted to the main reinforcement 21, thereby avoiding damage to the main reinforcement 21.

[0072] The pin stop plate 15 is used to prevent the pin shaft 22 from moving axially. The force exerted on the pin stop plate 15 by the pin shaft 22 is relatively weak. Therefore, a thinner pin stop plate 15 is provided to prevent the pin shaft 22 from falling off and reduce the overall deadweight of the pin stop seat 1 to avoid unnecessary waste of materials.

[0073] See also Figure 4 Optionally, the supporting plate 11 is an annular plate.

[0074] In this embodiment, the annular plate is easy to process and has a simple structure. It is understandable that the outer contour of the carrier plate 11 can also be other shapes, such as rectangular, elliptical, etc., and those skilled in the art can set it according to actual needs.

[0075] It should be noted that the inner contour of the carrier plate 11, that is, the through hole 12 formed by the inner edge of the carrier plate 11, needs to be slightly larger than the diameter of the pin 22, which can ensure that the pin 22 can be smoothly transmitted through the through hole 12 and can ensure that the pin 22 is in contact with the annular plate.

[0076] In some possible embodiments, the pin holder 1 further includes a reinforcing rib, and the reinforcing rib is arranged on the second wall surface 112 to avoid the mounting rib 13 .

[0077] In this embodiment, since the bearing plate 11 is used to withstand the extrusion and shearing forces from the pin shaft 22, reinforcing ribs are provided on the second wall surface 112 of the bearing plate 11. On the one hand, this will not affect the contact installation between the bearing plate 11 and the main rib 21. On the other hand, it can enhance the structural strength of the bearing plate 11 itself, which is beneficial to prevent the force at the pin shaft 22 from being transmitted to the main rib 21, thereby avoiding damage to the main rib 21.

[0078] Optionally, there are multiple reinforcing ribs, and the multiple reinforcing ribs are staggered to further improve the structural strength of the bearing plate 11, effectively buffer and withstand the forces of compression and shearing from the pin shaft 22, and prevent damage to the main ribs 21.

[0079] In some possible embodiments, the bearing plate 11 and the mounting ribs 13 are an integrated structure.

[0080] In this embodiment, the bearing plate 11 and the mounting rib 13 are an integrated structure. Compared with the post-processing method, the integrated processing has good mechanical properties and a higher connection strength of the overall structure. It can further buffer the force at the pin shaft 22 to ensure structural stability and durability. It is also beneficial to reduce the number of parts, thereby reducing the installation process and improving installation efficiency.

[0081] It should be noted that the bearing plate 11 and the mounting ribs 13 can be integrally formed by a casting process.

[0082] In some possible embodiments, the mounting ribs 13 are welded to the bearing plate 11 .

[0083] In this embodiment, the mounting ribs 13 can be welded to the bearing plate 11 , and the positions of the assembly and mounting ribs 13 can be flexibly set, which provides a higher degree of design freedom.

[0084] See also Figure 6 In some possible embodiments, the pin stop plate 15 includes a limiting portion 151 and a pin stop portion 152, wherein the limiting portion 151 is mounted on the mounting rib 13. The pin stop portion 152 is connected to the limiting portion 151 and extends into the mounting cavity 14, and the pin stop portion 152 is used to limit the axial movement of the pin shaft 22.

[0085] In this embodiment, the pin stop plate 15 includes a limiting portion 151 and a pin stop portion 152 . The width of the limiting portion 151 is greater than the width of the pin stop portion 152 , and the entirety is substantially in a “T” shape.

[0086] For example, when the first mounting rib 131 and the second mounting rib 132 are distributed on the upper and lower sides of the through hole 12, the first mounting rib 131 is located on the upper side, and the second mounting rib 132 is located on the lower side. When the pin stopper 15 is installed, the pin stopper 152 can successively pass through the first mounting cavity 141, the outer side of the through hole 12, and the second mounting cavity 142, and the limiting portion 151 is placed on the first mounting rib 131, thereby realizing the positioning and installation of the pin stopper 15, making the range of movement of the pin stopper 15, ensuring that the pin stopper 15 can abut against the end of the pin shaft 22, and limit the axial movement of the pin shaft 22.

[0087] It should be noted that the size D1 of the installation cavity 14 is larger than the size D2 of the stopper 152, ensuring that the stopper 152 can be smoothly introduced into the installation cavity 14. The size D1 of the installation cavity 14 is smaller than the size D3 of the limiter 151, ensuring that the limiter 151 can overlap the installation rib 13.

[0088] Optionally, the stopper plate 15 further includes a locking hole, which is provided at the end of the stopper portion 152 away from the limiting portion 151. The stopper seat 1 further includes a locking member 16, a part of which is passed through the locking hole to limit the movement of the stopper plate 15.

[0089] In this embodiment, a locking hole is provided at the stop pin portion 152 on the stop pin plate 15, and the axis of the locking hole is perpendicular to the axis of the pin shaft 22. After a portion of the locking member 16 is inserted into the locking hole, the end of the stop pin portion 152 cannot escape from the installation cavity 14, thereby limiting the movement of the stop pin plate 15. Optionally, the locking member 16 can be a D-type card.
