Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic supports for coal mines, and in particular to an assembly tooling for a fully mechanized hydraulic support. Background Technology

[0002] Fully mechanized hydraulic supports are one of the core pieces of equipment in fully mechanized coal mining faces. They are primarily used in underground coal mine longwall faces, undertaking key functions such as roof support, goaf management, and moving face equipment (e.g., coal mining machines, scraper conveyors). They are the "skeleton" equipment ensuring safe and efficient coal mining. The hydraulic support base is the core component that bears, connects, and stabilizes the entire fully mechanized hydraulic support, and its role is crucial throughout the entire process of support, movement, and safe operation of the support. The hydraulic support base consists of two main reinforcing plates (front and rear) and a base plate, with the two main reinforcing plates connected and assembled together by pins. The side-push jack is connected to the hydraulic support base to push or pull the fully mechanized hydraulic support. It is used to adjust the lateral posture of the fully mechanized hydraulic support and ensure that the support is arranged neatly on the working face. The connection part between the side-push jack and the hydraulic support base includes two horizontally spaced connecting components. Each connecting component includes a cylindrical round plate, a sleeve, and a pin seat. The round plate is installed in the positioning hole of the round plate that has been opened in advance on the main stiffener plate and one side is welded to the sleeve. The pin seat is fixed to the outside of the sleeve. The sleeve and the pin seat have through holes for the same pin shaft to pass through.

[0003] In existing technology, when assembling the connecting assembly on the main stiffening plate, positioning holes are pre-drilled on the main stiffening plate, and the circular plate and sleeve are welded together. Then, the operator marks lines on the main stiffening plate to determine the reference line for the connecting assembly. The sleeve and pin seat are connected by a pin shaft to ensure their through holes face the same direction. The direction of the sleeve and pin seat is adjusted, and they are then welded and fixed. The circular plate and positioning holes are welded and fixed. The pin shaft is then pulled out. Another connecting assembly is installed using the same method, completing the installation of the connecting assembly. The installation of the connecting assembly has the following problems: 1. Installation time is too long, as the positioning holes on the circular plate need to be pre-drilled, lines need to be marked, and the direction of the sleeve and pin seat needs to be adjusted; 2. Inconsistent adjustment angles, because the angles are adjusted manually, the orientation of the pin seats on each main stiffening plate cannot be guaranteed to be uniform, making it inconvenient to subsequently install the side-push jack.

[0004] Therefore, there is an urgent need for an assembly tooling for fully mechanized hydraulic supports that can save installation time of connecting components and keep the pin seat facing a specified angle. Utility Model Content

[0032] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1:

[0034] Reference Figures 1 to 5 This embodiment proposes an assembly fixture for a fully mechanized hydraulic support, used for installing the connecting component 1 of the side-push jack on the hydraulic support. Specifically, the assembly fixture for the fully mechanized hydraulic support in this embodiment includes a support plate 2 and several limiting components, as detailed below.

[0035] In this embodiment, the limiting members are at least two, and the limiting members cooperate with the main stiffening plate 3 of the hydraulic support base to form a fixed position for the support plate 2 on the main stiffening plate 3, thereby fixing the support plate 2 in a preset position on the main stiffening plate 3. The support plate 2 has several mounting positions for mounting the connecting component 1, and the mounting positions are adapted for the connecting component 1 to pass through the support plate 2 and abut against the main stiffening plate 3. Thus, the mounting positions have a shape adapted to the connecting component 1, which facilitates the connecting component 1 to pass through the support plate 2 and is suitable for the connecting component 1 to abut against and be positioned, thereby limiting it in a first direction parallel to the support plate 2 and a second direction parallel to the support plate 2. The first direction and the second direction are perpendicular to each other. The perpendicular first direction and the second direction can limit the connecting component 1 in different directions, which is beneficial for the placement of the connecting component 1 and provides convenience for subsequent fixing. Each mounting position on the support plate 2 is provided with a positioning element 4. The positioning element 4 is adapted to block the pin seat 11 from rotating further when the pin seat 11 of the connecting component 1 rotates to a specified angle, thereby providing the angle required for the installation of the pin seat 11. When the connecting component 1 is placed on the mounting position, the pin seat 11 directly determines its rotation angle, eliminating the need to confirm the angle of the pin seat 11 by scribing, reducing the installation steps of the connecting component 1, and eliminating the need to open the positioning hole of the circular plate 13 on the main stiffening plate 3. Moreover, the positioning hole area of ​​the circular plate 13 is large, which prolongs the production time of the main stiffening plate 3. The positioning element 4 is fixed to the support plate 2 by transition fitting with the opening on the support plate 2, welding to the support plate 2, or threaded connection to the support plate 2.

[0036] In summary, compared with the existing technology, the installation of the connecting component 1 on the hydraulic support base can be completed in one go by using several limiting parts and support plates 2. Moreover, the positioning part 4 prevents the pin seat 11 from continuing to rotate, and rotates the pin seat 11 to the specified angle, which facilitates the subsequent connection with the side push jack. Compared with the traditional technology, the step of opening the positioning hole of the circular plate 13 and marking the line is eliminated, which improves the installation efficiency of the connecting component 1.

[0037] Furthermore, the limiting component includes a first limiting rod 5, which transitionally engages with the positioning holes on the main stiffening plate 3. The positioning holes on the main stiffening plate 3 are uniformly drilled at the same position during the production of the main stiffening plate 3, and the diameter of the positioning holes on the main stiffening plate 3 is much smaller than that of the positioning holes on the circular plate 13. Compared with the latter, this reduces the production time of the main stiffening plate 3 and also reduces the waste of the main stiffening plate 3 material. Moreover, after the first limiting rod 5 is installed on the main stiffening plate 3, the horizontal distance between the first limiting rod 5 and the connecting component 1 is a fixed value. Thus, the installation position of the connecting component 1 on the support plate 2 is equal to the horizontal distance between the first limiting rod 5 and the connecting component 1, thereby limiting the position of the support plate 2 in the horizontal direction. At the same time, the direct contact between the support plate 2 and the first limiting rod 5 also facilitates the installation of the support plate 2.

[0038] Furthermore, the limiting component also includes multiple second limiting rods 6 fixed to the support plate 2. These second limiting rods are fixed to the support plate 2 by transition fitting with openings on the support plate 2, welding to the support plate 2, or threaded connection. The second limiting rods 6 are symmetrical about the support plate 2 and are clamped between the bottom of the main stiffening plate 3 and the mounting platform for assembling the hydraulic support base. The mounting platform for the hydraulic support base is where the hydraulic support base rests after the assembly fixture is installed for the installation of the connecting component 1. The second limiting rods 6 are located between the bottom of the main stiffening plate 3 and the mounting platform, facilitating their fixation and thus fixing the support plate 2. After the connecting component 1 is installed, the hydraulic support base can be lifted, and the assembly fixture removed. Since the second limiting rods 6 are symmetrical about the support plate 2, the difference between the length of the second limiting rod 6 extending beyond the support plate 2 and the length of the other limiting rods is the length of the second limiting rod 6 located between the bottom of the main stiffening plate 3 and the mounting platform. Multiple second limiting rods 6 are distributed at intervals along the bottom extension direction of the main stiffening plate 3. The bottom of the main stiffening plate 3 between the first limiting rod 5 and the connecting component 1 extends in the horizontal direction. Thus, multiple second limiting rods 6 are arranged at intervals in the horizontal direction at the bottom of the main stiffening plate 3 to limit the position of the support plate 2 in the vertical direction and fix the support plate 2 to one side of the installation platform.

[0039] Furthermore, the mounting position on the support plate 2 and the fitting portion of the connecting component 1 are arc-shaped and abut against the outer side of the sleeve 12 of the connecting component 1. The sleeve 12 is an annular cylindrical shape. Thus, when the mounting position on the support plate 2 is fitted with the connecting component 1, the mounting position on the support plate 2 is an arc-shaped shape with a diameter larger than the diameter of the sleeve 12. When the connecting component 1 abuts against the mounting position on the support plate 2, the connecting component 1 is located in its mounting position, which improves the installation speed of the connecting component 1 and simplifies the installation steps of the connecting component 1. After the support plate 2 is installed, the supporting plate 2 and the circular mounting plate 13 of the connecting component 1 are parallel to each other on opposite sides, which facilitates the positioning of the connecting component 1 during installation.

[0040] Furthermore, the central angle corresponding to the arc shape of the mounting position on the support plate 2 is within the range of 90°-180°. Moreover, the bottom of the mounting position on the support plate 2 also has a straight portion extending horizontally along the arc shape, and the connecting component 1 is located above the horizontally extending straight portion. Thus, the support plate 2 provides a certain supporting force for the connecting component 1, and when the connecting component 1 is subsequently welded and fixed, there is no need to hold the connecting component 1 by hand, which speeds up the fixing speed of the connecting component 1.

[0041] Furthermore, the positioning element 4 is fixed to the mounting position periphery on the support plate 2, and the positioning element 4 is symmetrically arranged about the support plate 2. The pin seat 11 of the connecting assembly 1 is fixed to the outside of the sleeve 12. Thus, the positioning element 4 is fixed within the range of the circle formed by the rotation of the pin seat 11 away from the side of the sleeve 12 around the sleeve 12. When the pin seat 11 rotates, the positioning element 4 can abut against the pin seat 11, so that the positioning element 4 can block the pin seat 11 from continuing to rotate, and the pin seat 11 faces the specified angle.

[0042] Furthermore, the limiting component also includes multiple third limiting rods 7 fixed to the support plate 2. The third limiting rods 7 are fixed to the support plate 2 by transition fitting with openings on the support plate 2, welding to the support plate 2, or threaded connection to the support plate 2. One end of the third limiting rod 7 abuts against the outer peripheral surface of the circular plate 13 and the main stiffening plate 3, and the multiple third limiting rods 7 are distributed in a ring around the periphery of the circular plate 13 to limit the installation position of the circular plate 13. In order to ensure that the plane between the support plate 2 and the main stiffening plate 3 from the first limiting rod 5 to the installation position of the connecting component 1 is parallel, a plurality of third limiting rods 7 abut against the main stiffening plate 3. At the same time, in order to define the installation position of the circular patch 13, the plurality of third limiting rods 7 abut against the periphery of the circular patch 13 in a ring distribution. When the circular patch 13 is located within the plurality of third limiting rods 7, the plurality of third limiting rods 7 limit the circular patch 13 within the plurality of third limiting rods 7, and the connecting component 1 can be welded to the main stiffening plate 3 without manual support, thus facilitating the fixation of the connecting component 1.

[0043] Furthermore, the limiting component also includes multiple fourth limiting rods 8 fixed to the support plate 2. The fourth limiting rods 8 are fixed to the support plate 2 by transition fitting with openings on the support plate 2, welding to the support plate 2, or threaded connection. The fourth limiting rods 8 are distributed around the periphery of the support plate 2 away from the third limiting rods 7, and one end of each fourth limiting rod 8 abuts against the main stiffening plate 3. Specifically, one end of both the fourth limiting rod 8 and the third limiting rod 7 abuts against the main stiffening plate 3, forming a support between the support plate 2 and the main stiffening plate 3. Both the fourth limiting rod 8 and the third limiting rod 7 are perpendicular to both the main stiffening plate 3 and the support plate 2. Therefore, the fourth limiting rod 8 and the third limiting rod 7 provide parallel support between the support plate 2 and the main stiffening plate 3, which helps to improve the installation speed of the assembly tooling.

[0044] Furthermore, both the third limiting rod 7 and the fourth limiting rod 8 are symmetrical about the support plate 2, and their lengths are the same. Thus, the third limiting rod 7 and the fourth limiting rod 8 are distributed on both sides of the entire support plate 2, and the side of the support plate 2 closest to the main stiffening plate 3 is held together by the third limiting rod 7 and the fourth limiting rod 8 to keep the support plate 2 and the main stiffening plate 3 parallel. Moreover, the distribution of the third limiting rod 7 and the fourth limiting rod 8 improves the stability of the support plate 2 and prevents it from shaking when fixing the connecting component 1. The other end of the third limiting rod 7 and the other end of the fourth limiting rod 8 are both located in a vertical plane parallel to the support plate 2. Therefore, whether the support plate 2 is parallel to the main stiffening plate 3 can be determined by whether the other end of the third limiting rod 7 and the other end of the fourth limiting rod 8 are located in the same plane, and the installation of the support plate 2 can be quickly determined.

[0045] Furthermore, in order to make the assembly tooling lightweight, the top of the support plate 2 has several notches, the shape of which can be cut according to requirements, and the inside of the support plate 2 has several through holes, the shape of which can be polygonal or circular according to requirements.

[0046] Example 2:

[0047] Reference Figures 6 to 9 This embodiment proposes a method for using an assembly fixture for a fully mechanized hydraulic support, including the following steps, which are detailed below.

[0048] S1. Install the assembly fixture onto the main stiffening plate 3 of the hydraulic support base;

[0049] S11. The main stiffening plate 3 is lifted on the installation platform. The first limiting rod 5 is fitted with the positioning hole opened in advance on the main stiffening plate 3. Then, the positioning part 4, the second limiting rod 6, the third limiting rod 7 and the fourth limiting rod 8 are vertically fixed on the support plate 2.

[0050] S12. The support plate 2 is brought into contact with the first limiting rod 5 and slowly lowered. The main stiffening plate 3 gradually comes into contact with the installation platform, thereby clamping the second limiting rod 6 between the main stiffening plate 3 and the installation platform. The positioning piece 4, the third limiting rod 7 and the fourth limiting rod 8 come into contact with the main stiffening plate 3, and the installation of the assembly tooling is completed.

[0051] S2. Install the connecting component 1 onto the main stiffening plate 3;

[0052] S21. Weld one side of the circular plate 13 in the connecting assembly 1 to the sleeve 12 and fix it. Connect the sleeve 12 and the pin seat 11 together by the pin shaft and fix the pin seat 11 and the sleeve 12 by welding.

[0053] S22. Place the two connecting components 1 from one side of the two mounting positions on the support plate 2 onto the main stiffening plate 3. The mounting positions abut against the sleeve 12, and rotate the pin counterclockwise to abut the pin seat 11 against the positioning part 4, thereby making the pin seat 11 face the specified angle.

[0054] After S3 and pin seat 11 are adjusted, the round plate 13 is welded and fixed to the main stiffening plate 3. Then the main stiffening plate 3 is lifted, the first limit bar 5 is removed from the positioning hole, and the assembly fixture is separated from the main stiffening plate 3.
