Description

Technical Field

[0001] This invention relates to the field of coal mining technology, and in particular to a tooling and installation method for installing a column pressure plate ear plate and a limiting connection seat. Background Technology

[0002] The hydraulic support base is a crucial component of the hydraulic support system. It serves not only as the force-transmitting component between the hydraulic support and the base plate but also as the connecting hub for multiple other components. It provides installation space for the column, control system, pushing device, and other auxiliary devices. Many components achieve functional collaboration through their connection to the base. The accuracy of the relative positional relationship between the column pressure plate lugs and the limiting connector on the base is particularly important. One end of the column pressure plate is connected to the mounting hole of the column pressure plate lugs via a pin, while the other end is inserted into the mounting groove of the limiting connector to press against the column trunnions on both sides of the column, thus limiting the movement of the column. In other words, when the column moves laterally or vertically, it causes the column pressure plate to rotate axially along the column pressure plate lugs. The column pressure plate lugs and the limiting connector cooperate through the connection of the column pressure plate to form a complete support and limiting system. This ensures the uniform distribution of the load on the column and guarantees that the column operates within a reasonable range of motion, thereby ensuring the overall performance and safety of the hydraulic support. The traditional assembly method involves manually measuring and marking lines to install the column pressure plate ear plate and the limiting connector on the main stiffening plate of the base. This method is not only time-consuming and labor-intensive, but also inefficient and has relatively poor installation accuracy. Therefore, the relative position between the two cannot be guaranteed.

[0003] Therefore, there is an urgent need for an assembly method that can be quick and convenient while ensuring the installation accuracy of both components. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a tooling and installation method for installing the column pressure plate ear plate and the limiting connection seat, which solves the technical problems of low efficiency and poor assembly accuracy in the traditional method of installing the column pressure plate ear plate and the limiting connection seat by manually measuring and marking on the base.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] On one hand, the present invention provides a tooling for installing the column pressure plate ear plate and the limiting connection seat of a hydraulic support, including a first positioning shaft, a horizontal positioning plate, a vertical positioning plate and a second positioning shaft.

[0009] The first positioning shaft includes a first end that can pass through the column socket positioning hole on the main stiffening plate of the base and a second end that can abut against the mounting groove of the limiting connection seat;

[0010] One end of the horizontal positioning plate is provided with a first circular through hole of the same size as the mounting hole on the column pressure plate ear plate, and the other end is provided with a groove that matches the outer peripheral surface of the second end of the first positioning shaft. The relative positional relationship between the first circular through hole and the groove is the same as the relative positional relationship between the mounting groove of the upper limit connecting seat of the base main stiffener plate and the mounting hole of the column pressure plate ear plate.

[0011] The width of the groove end in the horizontal positioning plate is equal to the width of the mounting groove, and the two are offset by the same angle relative to the vertical direction, so that the groove end can be inserted into the mounting groove.

[0012] One end of the vertical positioning plate is provided with a second circular through hole of the same size as the first circular through hole, and the other end is provided with an abutment end that can abut against the bottom surface of the main stiffener plate of the base. The vertical distance from the second circular through hole to the abutment end is the same as the distance from the column pressure plate ear plate on the main stiffener plate of the base to the bottom surface of the main stiffener plate of the base.

[0013] The second positioning axis is an optical axis, which can be simultaneously inserted into the first circular through hole, the second circular through hole, and the mounting hole.

[0014] Optionally, the first positioning shaft is a stepped shaft, with a small shaft section at the first end and a large shaft section at the second end. The outer diameter of the small shaft section is adapted to the inner diameter of the positioning hole in the column socket, and after it passes through the positioning hole, the side wall where the large shaft section meets the small shaft section can fit against the wall surface of the main stiffening plate of the base. The outer diameter of the large shaft section is adapted to the size of the mounting groove, and its outer peripheral wall can abut against the inner peripheral wall of the limiting mounting groove.

[0015] Optionally, the transverse positioning plate has an L-shaped structure including a horizontal plate and a vertical plate, with a first circular through hole at the free end of the horizontal plate and a groove at the free end of the vertical plate. The width of the vertical plate and its angle relative to the vertical direction are the same as the width of the mounting groove and its angle relative to the vertical direction.

[0016] Optionally, the abutting end of the vertical positioning plate is a positioning pin perpendicular to the surface of the vertical positioning plate, and the upper wall of the positioning pin can abut the lower bottom surface of the main stiffening plate of the base.

[0017] Optionally, two sets of locating pins are evenly arranged along the horizontal direction.

[0018] Optionally, the locating pin and the vertical locating plate are welded together to form an integral abutment end.

[0019] Optionally, the first end of the first positioning shaft and the core positioning hole, as well as the second positioning shaft and the first circular through hole, the second circular through hole, and the mounting hole are all clearance fits.

[0020] On the other hand, the present invention provides a method for installing the column pressure plate ear plate and the limiting connection seat of a hydraulic support, wherein the column pressure plate ear plate and the limiting connection seat are installed on the main stiffening plate of the base using any of the above-mentioned tooling.

[0021] Includes the following steps:

[0022] S1: Place the base main stiffener plate with the side of the installation limit connector facing upwards horizontally;

[0023] S2: Insert the first end of the first positioning shaft into the positioning hole of the column socket;

[0024] S3: The groove of the horizontal positioning plate abuts against the second end of the first positioning shaft, while ensuring that the vertical positioning plate is perpendicular to the bottom surface of the main stiffener plate of the base, and that the abutting end of the vertical positioning plate abuts against the bottom surface of the main stiffener plate of the base.

[0025] S4: Move the vertical positioning plate to a horizontal position and rotate the horizontal positioning plate at the same time so that the first circular through hole coincides with the second circular through hole and inserts the second positioning shaft.

[0026] S5: Place the limiting connector on the main stiffener plate of the base, so that the inner wall of its mounting groove fits against the outer peripheral wall of the second end of the first positioning shaft and the two side walls of the groove end of the transverse positioning plate. Then insert the column pressure plate ear plate into the second positioning shaft and rotate the column pressure plate ear plate so that its mounting surface fits completely against the mounting surface on the main stiffener plate of the base.

[0027] S6: Based on the limiting of the installation column pressure plate ear plate and the limiting connection seat in step S5, fix the two on the main stiffening plate of the base and remove the tooling.

[0028] Optionally, in step S6, the limiting connecting seat and the column pressure plate ear plate are fixedly installed by welding.

[0029] (III) Beneficial Effects

[0030] The beneficial effects of this invention are:

[0031] The present invention provides a fixture and installation method for installing a column pressure plate ear plate and a limiting connecting seat. On one hand, the fixture has a first circular through hole and a groove with the same relative positional relationship as the column pressure plate ear plate and the limiting connecting seat installed on the main rib of the base. After the fixture is positioned with the column socket positioning hole and the bottom surface of the main rib as references, the position of the column pressure plate ear plate and the limiting connecting seat can be quickly positioned according to the first circular through hole and groove, which is very efficient. Moreover, since the positional relationship between the two on the fixture is fixed and prefabricated, the assembly accuracy can be greatly improved.

[0032] On the other hand, based on the above-mentioned tooling, an installation method is provided. This tooling can quickly and accurately locate the position of the column pressure plate ear plate and the limiting connecting seat and install and fix them, avoiding the errors of manual measurement and marking, improving work efficiency, and providing one-time synchronous positioning, which can well ensure the assembly accuracy and ensure the accurate relative positional relationship between the two.

[0054] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "up," "down," "left," and "right" are used interchangeably. Figure 1 The orientation is used as a reference.

[0055] This invention proposes a fixture and installation method for installing a column pressure plate ear plate and a limiting connector. On one hand, it provides a fixture with a first circular through hole and a groove that have the same relative positional relationship as the column pressure plate ear plate and the limiting connector on the main rib of the base. After positioning the fixture with the column socket positioning hole and the bottom surface of the main rib as references, the position of the column pressure plate ear plate and the limiting connector can be quickly positioned according to the first circular through hole and groove, which is very efficient. Furthermore, since the positional relationship between the two on the fixture is fixed and prefabricated, the assembly accuracy can be greatly improved.

[0056] On the other hand, based on the above-mentioned tooling, an installation method is provided. This tooling can quickly and accurately locate the position of the column pressure plate ear plate and the limiting connecting seat and install and fix them, avoiding the errors of manual measurement and marking, improving work efficiency, and providing one-time synchronous positioning, which can well ensure the assembly accuracy and ensure the accurate relative positional relationship between the two.

[0057] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0058] Example 1:

[0059] Reference Figure 1 and Figure 2 This is a partial sectional view of the overall structure of the hydraulic support, in which column trunnions 501 are provided on both sides of the column 500 at the positions where they contact the main stiffening plate 100 of the base (e.g., Figure 3 As shown, two column trunnions 501 are respectively installed in the mounting grooves 201 of the upper limit connecting seat 200 of the main stiffening plate 100 of the base on both sides. One end of the column pressure plate 400 is connected to the column pressure plate ear plate 300 by a pin, and the other end is inserted into the mounting groove 201 of the limit connecting seat 200 to press the column trunnions 501 on both sides of the column 500. When the column 500 is working, it will move laterally or vertically. The column pressure plate 400 will be driven by the column trunnions 501 to rotate axially along the column pressure plate ear plate 300 in the mounting groove 201 of the limit connecting seat 200, thereby limiting the movement of the column 500 through the limit connecting seat 200 and the column pressure plate 400. Therefore, the accuracy of the relative positional relationship between the limit connecting seat 200 and the column pressure plate ear plate 300 is particularly important.

[0060] The tooling shown in this embodiment is for accurately positioning and installing two parts, the limiting connecting seat 200 and the column pressure plate ear plate 300, on the main stiffening plate 100 of the base. Therefore, the specific structure of the hydraulic support itself will not be described in detail.

[0061] Reference Figure 4 This embodiment provides a tooling for installing the column pressure plate ear plate and the limiting connection seat of a hydraulic support, including a first positioning shaft 1, a horizontal positioning plate 2, a vertical positioning plate 3 and a second positioning shaft 4.

[0062] like Figure 5As shown, the first positioning shaft 1 includes a first end 11 that can pass through the column socket positioning hole 101 on the main stiffening plate 100 of the base and a second end 12 that can abut against the mounting groove 201 of the limiting connecting seat 200. In this embodiment, the first positioning shaft 1 is a stepped shaft structure, with the first end 11 being a small shaft segment and the second end 12 being a large shaft segment. According to actual positioning requirements, the cross-sections of both the small and large shaft segments are circular, and the diameter of the small shaft segment is smaller than the diameter of the large shaft segment. Here, "small" and "large" are only a comparison of the size between the two shaft segments inside the reference stepped second positioning shaft 1, not absolute values, and are not compared with the second positioning shaft 4. The outer diameter of the small shaft segment is adapted to the inner hole size of the column socket positioning hole 101 so that it can pass through the column socket positioning hole 101; the outer diameter of the large shaft segment is adapted to the size of the mounting groove 201 of the limiting connecting seat 200 so that its outer peripheral wall can abut against the inner peripheral wall of the mounting groove of the limiting connecting seat 200.

[0063] like Figure 6 As shown, the transverse positioning plate 2 is an L-shaped structure including a horizontal plate 23 and a vertical plate 24. The free end of the horizontal plate 23 is provided with a first circular through hole 21 of the same size as the mounting hole 301 on the column pressure plate ear plate 300. The free end of the vertical plate 24 is provided with a groove 22 that is adapted to the outer circumferential surface of the second end 12 (i.e., the large shaft section). The relative positional relationship between the first circular through hole 21 and the groove 22 is the same as the relative positional relationship between the mounting groove 201 of the upper limit connecting seat 200 of the base main stiffener plate 100 and the mounting hole 301 of the column pressure plate ear plate 300. That is, the horizontal and vertical distances from the center of the first circular through hole 21 to the center of the bottom of the groove 22 are the same as the distances from the center of the mounting hole 301 of the column pressure plate ear plate 300 to the center of the bottom of the mounting groove 201 of the limit connecting seat 200. Meanwhile, the width of the end where the groove 22 of the horizontal positioning plate 2 is located (i.e. the width of the vertical plate 24) is equal to the width of the mounting groove 201 of the limiting connecting seat 200, and the two are offset at the same angle relative to the vertical direction, so that the end where the groove 22 of the horizontal positioning plate 2 is located can be inserted into the mounting groove 201 of the limiting connecting seat 200. In this embodiment, the shape and size of the horizontal positioning plate 2 are preferably designed with reference to the column pressure plate 400. It is only necessary to set the end of the column pressure plate 400 and the column trunnion 501 that is pressed together to form a groove that can be engaged with the large shaft section of the first positioning shaft 1.

[0064] like Figure 7 , Figure 8As shown, one end of the vertical positioning plate 3 is provided with a second circular through hole 31 of the same size as the first circular through hole 21, and the other end is provided with an abutment end 32 that can abut against the bottom surface of the main stiffening plate 100 of the base. The distance from the second circular through hole 31 to the abutment end 32 in the vertical direction is the same as the distance from the upper column pressure plate ear plate 300 of the main stiffening plate 100 to the bottom surface of the main stiffening plate 100 of the base. In this embodiment, the abutment end 32 is a positioning pin 33 perpendicular to the surface of the vertical positioning plate 3. The upper wall surface of the positioning pin 33 can abut against the bottom surface of the main stiffening plate 100 of the base. In order to facilitate the abutment and ensure that the vertical positioning plate 3 is not easy to shake after the abutment, it is preferable to evenly arrange two sets of positioning pins 33 in the horizontal direction and weld them to the vertical positioning plate 3 to form an integral abutment end 32. Of course, it is not limited to this. The abutment end 32 can also be other shapes or styles, such as a baffle, a block, a slot, etc., as long as the position of the abutment end 32 of the vertical positioning plate 3 can abut against the bottom surface of the main stiffener plate 100 of the base.

[0065] like Figure 9 As shown, the second positioning shaft 4 is an optical shaft whose outer diameter is adapted to the inner diameter of the mounting hole 301, and it can be simultaneously inserted into the first circular through hole 21, the second circular through hole 31 and the mounting hole 301.

[0066] The above descriptions of the compatibility between components all refer to the inner diameter of the hole or the opening size of the groove being slightly larger than the size of the shaft, so that the hole and shaft or groove and shaft can form a clearance fit, which facilitates installation and disassembly.

[0067] In use, the first positioning shaft 1, the horizontal positioning plate 2, the vertical positioning plate 3, and the second positioning shaft 4 need to cooperate with each other. The groove 23 of the horizontal positioning plate 2 is engaged with the outer peripheral wall of the main shaft section of the first positioning shaft 1. The second positioning shaft 4 is passed through the first circular through hole 21 on the horizontal positioning plate 2 and the second circular through hole 31 on the vertical positioning plate 3 in sequence. At this time, the fixture has two free ends, namely the abutting end 32 of the first positioning shaft 1 and the vertical positioning plate 3. By selecting the column socket positioning hole 101 and the bottom surface of the main rib plate 100 of the base as the reference, the first positioning shaft 1 is fixed with the column socket positioning hole 101, and the abutting end 32 is abutted with the bottom surface of the main rib plate 100 of the base. The entire fixture will be limited and fixed. Then, based on the position of the fixture, the limiting connecting seat 200 and the column pressure plate ear plate 300 are installed. The operation is very convenient and the positioning is accurate. Meanwhile, the positional relationship between the first circular through hole 21 and the groove 22 pre-set on the tooling is fixed. Therefore, when installing the limit connecting seat 200 and the column pressure plate ear plate 300, the relative positional relationship between the two can be well guaranteed, ensuring the installation accuracy.

[0068] Example 2:

[0069] Reference Figure 10This embodiment provides a method for installing the column pressure plate ear plate and the limiting connection seat of a hydraulic support. The tooling of Embodiment 1 is used to install the column pressure plate ear plate 300 and the limiting connection seat 200 onto the main stiffening plate 100 of the base.

[0070] Includes the following steps:

[0071] S1: Place the base main stiffener plate 100 with the side of the installation limit connecting seat 200 facing upwards and horizontally;

[0072] S2: Insert the first end 11 of the first positioning shaft 1 into the positioning hole 101 in the column socket;

[0073] S3: The groove 22 of the horizontal positioning plate 2 is abutted against the second end 12 of the first positioning shaft 1, while ensuring that the vertical positioning plate 3 is perpendicular to the bottom surface of the main stiffener plate 100 of the base, and that the abutting end 32 abuts against the bottom surface of the main stiffener plate 100 of the base.

[0074] S4: Move the vertical positioning plate 3 to a horizontal position and rotate the horizontal positioning plate 2 at the same time so that the first circular through hole 21 coincides with the second circular through hole 31 and the second positioning shaft 4 is inserted.

[0075] S5: Place the limiting connecting seat 200 on the main stiffening plate 100 of the base, so that the inner wall of its mounting groove 201 fits against the outer peripheral wall of the second end 12 and the two side walls of the groove 22 end. Then, insert the column pressure plate ear plate 300 into the second positioning shaft 4 and rotate the column pressure plate ear plate 300 so that its mounting surface fits completely against the mounting surface on the main stiffening plate 100 of the base.

[0076] S6: Based on the limiting of the installation column pressure plate ear plate 300 and the limiting connecting seat 200 in step S5, fix the two on the base main stiffening plate 100 and remove the tooling.

[0077] Reference Figure 11 The following is a detailed discussion of each step:

[0078] Regarding step S1:

[0079] In this embodiment, the base main stiffener plate 100 is placed horizontally on the operating surface with one side of the mounting limit connecting seat 200 facing upward. At this time, the column socket positioning hole 101 on it is perpendicular to the operating surface. The operating surface can be a horizontal ground or other table surface that is convenient for operation.

[0080] Regarding step S2:

[0081] In this embodiment, the small shaft segment (i.e., the first end 11) of the first positioning shaft 1 is inserted into the positioning hole 101 of the column socket until the side wall where the large shaft segment and the small shaft segment meet is in contact with the wall surface of the main stiffener plate 100 of the base, which means it is installed in place. At this time, there is a clearance fit between the small shaft segment and the positioning hole 101 of the column socket, which is convenient for disassembly and assembly and accurate for positioning.

[0082] Regarding step S3:

[0083] In this embodiment, the groove 22 of the transverse positioning plate 2 is abutted against the large shaft section (i.e., the second end 12) of the first positioning shaft 1, that is, the inner surface of the groove 22 is in contact with the outer surface of the large shaft section of the first positioning shaft 1, and the opening of the L-shaped structure formed between the horizontal plate 23 and the vertical plate 24 faces the bottom surface of the main stiffener plate 100 of the base. At this time, the movement of the transverse positioning plate 2 is restricted, and it can only rotate around the large shaft section of the first positioning shaft 1.

[0084] At the same time, the vertical positioning plate 3 is attached to the wall of the main stiffening plate 100 so that it is perpendicular to the bottom surface of the base main stiffening plate 100. The position of the vertical positioning plate 3 is adjusted so that the upper wall surfaces of the two positioning pins 33 (i.e., the abutting end 32) on it abut against each other on the bottom surface of the base main stiffening plate 100. At this time, the vertical positioning plate 3 can no longer move along its length direction, but can only move left and right along the bottom surface of the base main stiffening plate 100.

[0085] Regarding step S4:

[0086] In this embodiment, based on the limiting of the horizontal positioning plate 2 and the vertical positioning plate 3 in step S3,

[0087] The position of the vertical positioning plate 3 is translated along the bottom surface of the main rib plate 100 of the base, and the horizontal positioning plate 2 is rotated around the main axis of the first positioning shaft 1 at the same time, so that the first circular through hole 21 and the second circular through hole 31 coincide. Then, the second positioning shaft 4 is inserted into the first circular through hole 21 and the second circular through hole 31 at the same time. At this time, the horizontal positioning plate 2 and the vertical positioning plate 3 restrain each other and can no longer move. That is, the position of the tooling has been fixed.

[0088] Regarding step S5:

[0089] In this embodiment, the limiting connecting seat 200 is placed on the main stiffening plate 100 of the base, so that the inner wall of its mounting groove 201 is in contact with the outer peripheral wall of the large shaft section (i.e., the second end 12) of the first positioning shaft 1 and the two side walls of the groove 22 end (i.e., the two side walls of the vertical side of the horizontal positioning plate 2). At this time, the position of the limiting connecting seat 200 is fixed.

[0090] Next, insert the column pressure plate ear plate 300 into the second positioning shaft 4 and rotate the column pressure plate ear plate 300 so that its mounting surface is completely in contact with the mounting surface on the main stiffener plate 100 of the base. At this time, the position of the column pressure plate ear plate 300 is fixed.

[0091] Regarding step S6:

[0092] In this embodiment, based on the limiting of the column pressure plate ear plate 300 and the limiting connecting seat 200 in step S5, the two are welded to the main stiffening plate 100 of the base respectively, and the tooling is removed.

[0093] In this embodiment, the limiting connector 200 and the column pressure plate ear plate 300 are installed with the assistance of tooling. Using the column socket positioning hole 101 and the lower surface of the base main stiffener plate 100 as positioning references, the relative positional relationship between the two parts is ensured to be accurate. Furthermore, the reference for installing the limiting connector 200 and the column pressure plate ear plate 300 on multiple base plate main stiffener plates 100 is consistent. Therefore, this not only ensures the smooth assembly of the subsequent hydraulic support assembly column pressure plate 400, but also ensures uniform force distribution on both sides of the column 500, thereby guaranteeing the overall working performance and safety of the hydraulic support. At the same time, using this method to install the limiting connector 200 and the column pressure plate ear plate 300 avoids errors from manual measurement and marking, and also improves work efficiency.
