Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic support installation devices, and particularly to an installation device and installation method for the top-cover hinge pin in a hydraulic support. Background Art

[0002] A hydraulic support is a structure used to control the mine pressure in a coal mining face. The mine pressure in the face acts on the hydraulic support in the form of external load. In the mechanical system of the interaction between the hydraulic support and the surrounding rock of the face, if the resultant force of each support member of the hydraulic support and the resultant force of the external load acting on the hydraulic support by the roof are exactly on the same straight line, then the hydraulic support is very suitable for the surrounding rock of this face.

[0003] Among them, the top beam and the shield beam in the hydraulic support play a major role. The top beam is the main load-bearing component of the hydraulic support, responsible for supporting the roof and ensuring the safety of the working space; the shield beam and the front and rear connecting rods form a four-bar linkage mechanism, directly bearing the load of the falling gangue and the bending moment caused by the horizontal load transmitted by the roof through the top beam, enhancing the anti-torsion performance of the support. The top beam and the shield beam are hinged by a hinge pin to achieve the connection between the two.

[0004] Currently, when installing the top beam and the shield beam, most of the hinge pins are installed manually. However, the single weight of the hinge pin often exceeds 200 kg, and at least two workers are required to lift it. Since manual handling not only consumes a large amount of physical strength, but also easily causes workers to fatigue during long-term operation, increasing the risk of operation errors. Secondly, considering that the installation position is usually at a relatively high place, which belongs to the category of working at heights, this way of working at heights further exacerbates the complexity and danger of the work, reducing the installation efficiency.

[0005] Therefore, there is an urgent need for an installation device that can install the hinge pins of the top beam and the shield beam, so as to improve the installation efficiency, reduce the labor intensity, and improve the safety. Summary of the Invention

Detailed implementation manners

[0041] For better explaining the present invention and facilitating understanding, the present invention will be described in detail below with reference to the accompanying drawings and through specific implementation manners.

[0042] Embodiment 1

[0043] As Figure 1 shown, the installation device of the hinge pin of the top shield in the hydraulic support of this embodiment. The hydraulic support includes a roof beam 1, a shield beam 2, and two hinge pins 3. The two hinge pins 3 are used to hinge the roof beam 1 and the shield beam 2. The installation device includes a pushing mechanism 4, a clamping mechanism 5, and two thrust mechanisms 6. Among them, the hinge pin 3 of the top shield is the hinge pin 3 used for hinging in the roof beam 1 and the shield beam 2.

[0044] Specifically, as Figure 2As shown in the figure, the pushing mechanism 4 and the clamping mechanism 5 are horizontally arranged opposite to each other. Both ends of the pushing mechanism 4 are respectively connected to two pushing mechanisms 6. The pushing ends of the two pushing mechanisms 6 are both located below the pushing mechanism 4, and the two pushing ends can be detachably connected to the two hinge pins 3 respectively. The clamping mechanism 5 is connected to the pushing mechanism 4 through a connecting beam 7. The clamping mechanism 5 can be telescoped to clamp the installation device on the top beam 1. The pushing mechanism 4 can be telescoped and can drive the two pushing mechanisms 6 to move horizontally respectively, so that the pushing mechanisms 6 can respectively push the two hinge pins 3 to move towards the position close to the center of the top beam 1 to install the top beam 1 and the shield beam 2. By setting the clamping mechanism 5, it can firmly clamp the installation device on the top beam 1, so that the pushing mechanism 4 and the pushing mechanism 6 can be more stable when installing the hinge pin 3. By setting the pushing mechanism 4, it can drive the pushing mechanism 6 to move horizontally, so as to push the hinge pin 3, so as to install the top beam 1 and the shield beam 2 through the hinge pin 3, greatly shortening the time required for the whole installation process and improving the work efficiency. The installation of the traditional hinge pin 3 requires multiple workers to cooperate, and heavy objects are carried and installed at a high place. For workers, the labor intensity is high, and it is extremely easy to be dangerous during high-altitude operations, and the safety is low. However, in the present invention, by setting the clamping mechanism 5, the pushing mechanism 4 and the pushing mechanism 6, it is realized that the hinge pin 3 does not need to be manually carried and installed, reducing the labor intensity and making the installation process of the top beam 1 and the shield beam 2 easier and safer. Moreover, through the clamping mechanism 5, the pushing mechanism 4 and the pushing mechanism 6, both the clamping mechanism 5 and the pushing mechanism 4 can be telescoped, so that the installation device can install the top beam 1 and the shield beam 2 with different specifications and sizes, improving the applicability of the installation device.

[0045] Furthermore, as Figure 2 shown in the figure, the pushing mechanism 4 includes two sets of pushing components 41. The two sets of pushing components 41 have the same structure and are symmetrically arranged with respect to the midline of the connecting beam 7. The telescopic ends of the two sets of pushing components 41 are respectively connected to the two pushing mechanisms 6. The two sets of pushing components 41 can respectively drive the two pushing mechanisms 4 to move horizontally, so that the two pushing mechanisms 6 can respectively push the two hinge pins 3. By setting the two sets of pushing components 41, and the two sets of pushing components 41 can be independently telescoped and moved to respectively drive the two pushing mechanisms 6 to perform horizontal movement, so that the two hinge pins 3 can be pushed separately or synchronously, improving the work efficiency. Moreover, since the two sets of pushing components 41 can independently adjust their telescopic ranges, the installation device can be applicable to the installation of the top beam 1 and the shield beam 2 with various specifications and sizes, improving the applicability and versatility.

[0046] Furthermore, as Figure 2As shown, the pushing component 41 includes a pushing jack 411, a first telescopic beam 412, a pushing beam 413, and a first connecting plate 414. The first telescopic beam 412 is vertically connected to the connecting beam 7. The fixed ends of the two first telescopic beams 412 are connected relatively. The telescopic end of the first telescopic beam 412 is connected to the pushing beam 413, and the pushing beam 413 is connected to the pushing mechanism 6. The first connecting plate 414 is installed on the connecting plate and is located between the two pushing jacks 411. The fixed ends of the two pushing jacks 411 are respectively hinged to both ends of the first connecting plate 414, and the telescopic ends of the two pushing jacks 411 are respectively hinged to the tops of the two pushing beams 413. The pushing jack 411 can drive the pushing beam 413 to move horizontally, so as to drive the first telescopic beam 412 to expand and contract, thereby driving the pushing mechanism 6 to push the hinge pin 3. By setting the pushing jack 411, the first telescopic beam 412, and the pushing beam 413, it can be realized that only by driving the pushing jack 411, the pushing beam 413 can be driven to move horizontally, and the first telescopic beam 412 expands and contracts synchronously, so that the pushing beam 413 drives the pushing mechanism 6 to push the hinge pin 3, realizing the installation of the top beam 1 and the shield beam 2, with simple operation and improved work efficiency. At the same time, through the first telescopic beam 412, it can guide the pushing direction of the pushing jack 411, and at the same time, it can also provide a supporting effect for the pushing beam 413, improving the stability of the pushing mechanism 4.

[0047] Here, it should be noted that the two first telescopic beams 412 can also be an integral first telescopic beam 412, and both ends of one first telescopic beam 412 can be driven to expand and contract by the two pushing jacks 411.

[0048] Furthermore, as Figure 2 and Figure 6 shown, the pushing mechanism 6 includes a push rod 61 and a box body 62. The top of the box body 62 is vertically inserted into the pushing beam 413 and is installed on the pushing beam 413 through a fixing pin 8. It can be realized that once the pushing mechanism 6 is damaged, only by removing the fixing pin 8, the box body 62 and the push rod 61 can be disassembled, thus facilitating the replacement of the pushing mechanism 6. The bottom of the box body 62 is exposed outside the pushing beam 413. The push rod 61 is installed on the bottom side wall of the box body 62 facing the connecting beam 7. The end of the push rod 61 away from the box body 62 is the pushing end for installing the hinge pin 3. By setting the push rod 61, the push rod 61 can push the hinge pin 3 through the action of the pushing jack 411 and the pushing beam 413, so that it is no longer necessary for workers to manually install the hinge pin 3, significantly reducing the labor intensity of workers. At the same time, it also avoids workers working at heights and reduces the safety risks that workers may face during the installation process.

[0049] Furthermore, as Figure 7As shown, a plurality of round holes 621 are provided on the box body 62. The plurality of round holes 621 are vertically spaced apart, and the axes of the plurality of round holes 621 are located on the same vertical line. The fixing pin 8 can pass through the pushing beam 413 and be inserted into any one of the round holes 621 to adjust the extending length of the box body 62, so that only by adjusting the fixing pin 8, the extending length of the box body 62 can be quickly changed, thereby changing the position height of the ejector rod 61, so that the installation device can install the hinge pin 3 on the hinge holes with different heights on the top beam 1 and the shield beam 2 with different specifications and sizes, improving the applicability and versatility of the installation device.

[0050] Furthermore, as Figure 4 and Figure 5 shown, the pushing mechanism 6 further includes an extension rod 63. One end of the extension rod 63 is detachably connected to the pushing end, and the other end is detachably connected to the hinge pin 3 to extend the length of the ejector rod 61. By providing the extension rod 63, when the one side of the top beam 1 facing the movable side guard plate is in the case where the movable side guard plate is not retracted, since the initial ejector rod 61 cannot push the hinge pin 3 to the installation position, therefore, by installing the extension rod 63 on the ejector rod 61, it can extend the length of the ejector rod 61, so that the pushing mechanism 6 can install the hinge pin 3 in place at one time, improving the applicability and versatility of the installation device.

[0051] Furthermore, as Figure 2As shown in the figure, the clamping mechanism 5 includes a clamping jack 51, a second telescopic beam 52, a second connecting plate 53, and two clamping members 54. The second telescopic beam 52 is perpendicularly connected to the connecting beam 7. The fixed end and the telescopic end of the second telescopic beam 52 are respectively perpendicularly connected to the two clamping members 54. The second connecting plate 53 is installed on the connecting beam 7. The fixed end of the clamping jack 51 is hinged to the second connecting plate 53, and the telescopic end of the clamping jack 51 is hinged to the telescopic end of the second telescopic beam 52. The clamping jack 51 can drive the telescopic end of the second telescopic beam 52 to expand and contract, so as to drive the clamping member 54 connected to the telescopic end of the second telescopic beam 52 to move laterally, so as to clamp the installation device on the top beam 1. By setting the clamping jack 51, the second telescopic beam 52, and the two clamping members 54, the two clamping members 54 can stably clamp the installation device on the top beam 1, so that the pushing mechanism 4 and the pushing mechanism 6 are more stable when installing the top beam 1 and the shield beam 2. Its operation is simple, the work efficiency is improved, and the stability is improved. Moreover, through the action of the clamping jack 51 and the second telescopic beam 52, the clamping mechanism 5 can clamp the top beam 1 of different specifications and sizes, improving the applicability and versatility of the installation device. Preferably, the clamping member 54 is a clamping beam or a magnet, both of which can provide a stable clamping force for the installation device. When the clamping member 54 is set as a clamping beam, the two clamping beams can jointly provide a clamping force, with a large clamping strength, avoiding the falling of the installation device and improving the stability. When the clamping member 54 is set as a magnet, it can be quickly adsorbed on the top beam 1, and the adsorption force of the magnet is evenly distributed on the entire contact surface of the top beam 1, avoiding potential safety hazards caused by excessive local pressure.

[0052] Furthermore, as Figure 2 shown, the installation device further includes a plurality of ring chains 9. The plurality of ring chains 9 are respectively detachably installed on the opposite side walls of the first telescopic beam 412 and the second telescopic beam 52, and are used to cooperate with the overhead crane to hoist the installation device, preventing the installation device from falling due to unstable installation and improving safety. Through the plurality of ring chains 9, the balance and stability of the installation device during hoisting are ensured. Moreover, it can also quickly move the installation device to the next working station through the plurality of ring chains 9, improving the work efficiency of installation.
