Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic support installation devices, and in particular to an installation device for the top hinge pin of a hydraulic support. Background Technology

[0002] Hydraulic supports are structures used to control mine pressure in coal mining faces. The mine pressure acts on the hydraulic supports as an external load. In the mechanical system of interaction between the hydraulic supports and the surrounding rock of the mining face, if the resultant force of all supporting components of the hydraulic support is exactly linear with the resultant force of the external load acting on the hydraulic support from the roof, then the hydraulic support is highly suitable for the surrounding rock of that mining face.

[0003] Among them, the top beam and shield beam in the hydraulic support play a significant 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, which directly bears the load of falling gangue and the bending moment caused by the horizontal load transmitted by the roof through the top beam, thereby enhancing the torsional resistance of the support. The top beam and the shield beam are hinged together by a hinge pin to achieve the connection between the two.

[0004] Currently, the installation of the top beam and shield beam is mostly done manually by installing the articulated pins. However, a single articulated pin often weighs over 200 kg, requiring at least two workers to lift it. Manual handling is not only physically demanding but also prone to worker fatigue during prolonged work, increasing the risk of operational errors. Furthermore, considering that the installation location is usually at a high altitude, falling under the category of working at heights, this method further exacerbates the complexity and danger of the work, reducing installation efficiency.

[0005] Therefore, there is an urgent need for an installation device that can install hinged pins for the top beam and the shield beam, in order to improve installation efficiency, reduce labor intensity, and improve safety. Utility Model Content

Detailed Implementation

[0031] 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.

[0032] Example 1

[0033] like Figure 1 As shown in this embodiment, the hydraulic support includes a top beam 1, a shield beam 2, and two hinge pins 3. The two hinge pins 3 are used to hinge the top beam 1 and the shield beam 2. The installation device includes a pushing mechanism 4, a clamping mechanism 5, and two pushing mechanisms 6. The top shield hinge pins 3 are the hinge pins 3 used for hinged connection between the top beam 1 and the shield beam 2.

[0034] Specifically, such as Figure 2As shown, the pushing mechanism 4 and the clamping mechanism 5 are arranged horizontally opposite each other. Both ends of the pushing mechanism 4 are connected to two pushing mechanisms 6, with the pushing ends of the two pushing mechanisms 6 located below the pushing mechanism 4. Each pushing end can be detachably connected to one of the two hinge pins 3. The clamping mechanism 5 is connected to the pushing mechanism 4 via a connecting beam 7. The clamping mechanism 5 is telescopic and is used to clamp the installation device onto the top beam 1. The pushing mechanism 4 is telescopic and can drive the two pushing mechanisms 6 to move laterally, allowing the pushing mechanisms 6 to push the two hinge pins 3 towards a position closer to the center of the top beam 1, thus installing the top beam 1 and the protective beam 2. By setting the clamping mechanism 5, the installation device can be securely clamped onto the top beam 1, thereby making the pushing mechanism 4 and the pushing mechanism 6 more stable when installing the hinge pins 3. By setting up a pushing mechanism 4, it can drive the pushing mechanism 6 to move laterally, thereby pushing the hinge pin 3 to install the top beam 1 and the shield beam 2 through the hinge pin 3. This greatly shortens the time required for the entire installation process and improves work efficiency. Traditionally, the installation of the hinge pin 3 requires multiple workers to work together, involving heavy lifting and installation at heights. This is physically demanding and dangerous, with low safety standards. This invention, by setting up a clamping mechanism 5, a pushing mechanism 4, and a pushing mechanism 6, eliminates the need for manual handling and installation of the hinge pin 3, reducing labor intensity and making the installation of the top beam 1 and the shield beam 2 easier and safer. Furthermore, the clamping mechanism 5 and the pushing mechanism 4 are all telescopic, allowing the installation device to install top beams 1 and shield beams 2 of different specifications and sizes, improving the applicability of the installation device.

[0035] Furthermore, such as Figure 2 As shown, the pushing mechanism 4 includes two sets of pushing components 41. The two sets of pushing components 41 have identical structures and are symmetrically arranged around the centerline of the connecting beam 7. The telescopic ends of the two sets of pushing components 41 are respectively connected to two pushing mechanisms 6. The two sets of pushing components 41 can drive the two pushing mechanisms 4 to move laterally, so that the two pushing mechanisms 6 can respectively push against the two hinge pins 3. By setting two sets of pushing components 41, and the fact that the two sets of pushing components 41 can extend, retract, and move independently to drive the two pushing mechanisms 6 to move laterally, the two hinge pins 3 can be advanced individually or simultaneously, improving work efficiency. Furthermore, since the telescopic range of the two sets of pushing components 41 can be adjusted independently, the installation device can be applied to the installation of top beams 1 and shield beams 2 of various specifications and sizes, improving applicability and versatility.

[0036] Furthermore, such as Figure 2As shown, the pushing assembly 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 perpendicularly connected to the connecting beam 7, the fixed ends of the two first telescopic beams 412 are connected opposite each other, the telescopic ends of the first telescopic beams 412 are connected to the pushing beam 413, and the pushing beam 413 is connected to the pushing mechanism 6. The first connecting plate 414 is mounted 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 the two 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 jacks 411 can drive the pushing beams 413 to move laterally, thereby driving the first telescopic beams 412 to extend and retract, which in turn drives the pushing mechanism 6 to push the hinge pin 3. By configuring a pushing jack 411, a first telescopic beam 412, and a pushing beam 413, the system enables the pushing beam 413 to move laterally simply by driving the pushing jack 411. Simultaneously, the first telescopic beam 412 extends and retracts, allowing the pushing beam 413 to drive the pushing mechanism 6 to push against the hinge pin 3, thus achieving the installation of the top beam 1 and the protective beam 2. This simplifies operation and improves work efficiency. Furthermore, the first telescopic beam 412 guides the pushing direction of the pushing jack 411 and provides support for the pushing beam 413, enhancing the stability of the pushing mechanism 4.

[0037] It should be noted that the two first telescopic beams 412 can also be a single first telescopic beam 412. The two ends of a single first telescopic beam 412 can be extended and retracted by two push jacks 411.

[0038] Furthermore, such as Figure 2 and Figure 6 As shown, the pushing mechanism 6 includes a push rod 61 and a housing 62. The top of the housing 62 is vertically inserted into the pushing beam 413 and is mounted on the pushing beam 413 by a fixing pin 8. This allows the housing 62 and push rod 61 to be easily removed and replaced if the pushing mechanism 6 is damaged, simply by removing the fixing pin 8. The bottom of the housing 62 is exposed outside the pushing beam 413. The push rod 61 is mounted on the bottom side wall of the housing 62 facing the connecting beam 7. The end of the push rod 61 away from the housing 62 is the pushing end, used to install the hinge pin 3. By setting the push rod 61, it can push the hinge pin 3 through the action of the pushing jack 411 and the pushing beam 413, thus eliminating the need for manual installation of the hinge pin 3 and significantly reducing the labor intensity of workers. At the same time, it also avoids workers working at heights, reducing the safety risks that workers may face during installation.

[0039] Furthermore, such as Figure 7As shown, the housing 62 is provided with multiple circular holes 621, which are arranged vertically at intervals, and the axes of the multiple circular 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 circular holes 621 to adjust the extension length of the housing 62. Thus, by simply adjusting the fixing pin 8, the extension length of the housing 62 can be quickly changed, thereby changing the position and height of the top rod 61. This allows the installation device to install the hinge pin 3 on hinge holes of different heights on the top beam 1 and the shield beam 2 of different specifications and sizes, improving the applicability and versatility of the installation device.

[0040] Furthermore, such as Figure 4 and Figure 5 As shown, the pushing mechanism 6 also 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 push rod 61. By providing the extension rod 63, when one side of the top beam 1 is a movable side guard plate and the movable side guard plate is not retracted, the initial push rod 61 cannot push the hinge pin 3 to the installation position. Therefore, by installing the extension rod 63 on the push rod 61, the length of the push rod 61 can be extended, thereby enabling the pushing mechanism 6 to install the hinge pin 3 into place in one go, improving the applicability and versatility of the installation device.

[0041] Furthermore, such as Figure 2As shown, 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, and its fixed end and telescopic end are respectively perpendicularly connected to the two clamping members 54. The second connecting plate 53 is mounted 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 extend and retract, thereby causing the clamping members 54 connected to the telescopic end of the second telescopic beam 52 to move laterally, thus clamping the installation device onto the top beam 1. By incorporating a clamping jack 51, a second telescopic beam 52, and two clamping members 54, the installation device can be stably clamped onto the top beam 1 by the two clamping members 54. This makes the pushing mechanism 4 and the pushing mechanism 6 more stable when installing the top beam 1 and the protective beam 2. The operation is simple, improving work efficiency and stability. Furthermore, through the action of the clamping jack 51 and the second telescopic beam 52, the clamping mechanism 5 can clamp top beams 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. Using a clamping beam as the clamping member 54 allows two clamping beams to jointly provide clamping force, resulting in high clamping strength, preventing the installation device from falling, and improving stability. Using a magnet as the clamping member 54 allows it to quickly adhere to the top beam 1, with the magnetic attraction force evenly distributed across the entire contact surface of the top beam 1, avoiding safety hazards caused by excessive local pressure.

[0042] Furthermore, such as Figure 2 As shown, the installation device also includes multiple circular chain links 9. These links 9 are detachably mounted on the opposite sidewalls of the first telescopic beam 412 and the second telescopic beam 52, respectively, for use in conjunction with the overhead crane to hoist the installation device. This prevents the installation device from falling due to instability and improves safety. The multiple chains 9 also ensure the balance and stability of the installation device during hoisting. Furthermore, the multiple chains 9 can quickly move the installation device to the next work position, improving installation efficiency.

[0043] Example 2

[0044] The installation method of the top hinge pin in the hydraulic support of this embodiment adopts the installation device of Embodiment 1 and further includes the following steps:

[0045] S1: Preparations before installation.

[0046] S11: The base, shield beam 2, and connecting rod of the hydraulic support are assembled on the ground, and the conditions for installing the top beam 1 are met.

[0047] S12: Insert the two hinge pins 3 onto the top beam 1.

[0048] S13: Simultaneously drive the clamping jack 51 and the two pushing jacks 411 to extend the preset maximum distance, and the pushing jacks 411 drive the pushing mechanism 6 to move toward the center position away from the installation device.

[0049] S2: Start installation.

[0050] S21: Connect the installation device to the overhead crane via the circular chain 9. The overhead crane moves the installation device to place it on the top beam 1.

[0051] S22: Drive the clamping jack 51 to retract, so that the installation device is clamped onto the top beam 1 by the two clamping members 54, as shown. Figure 1 As shown.

[0052] S23: When both sides of the top beam 1 are fixed side guard plates and movable side guard plates, connect the two hinge pins 3 to the two top rods 61 respectively, as follows: Figure 3 As shown.

[0053] S24: Drive the push jack 411 to retract, so as to drive the two push rods 61 to move laterally towards the top beam 1, so that the two push rods 61 push against the two hinge pins 3 inserted into the hinge holes on both sides of the top beam 1 and the shield beam 2, so as to hinge the top beam 1 and the shield beam 2.

[0054] S25: As Figure 5 As shown, when one side of the top beam 1 is a fixed side guard plate and the other side is a movable side guard plate, the hinge pin 3 is pushed in step S24. The top rod 61 on the movable side guard plate can only push the hinge pin 3 past the outer main reinforcement of the shield beam 2 through the push jack 411. Then, the push jack 411 on the current side is driven to extend, driving the top rod 61 to move away from the top beam 1. After moving a certain distance, the push jack 411 is stopped. An extension rod 63 is installed at the end of the top rod 61 away from the box 62. The push jack 411 is driven to retract until the extension rod 63 can be connected to the hinge pin 3. Then, the hinge pin 3 is connected to the extension rod 63. The push jack 411 is driven to retract again until the hinge pin 3 is pushed to the installation position.

[0055] S26: After the top beam 1 and the shield beam 2 are installed, remove the two hinge pins 3 from the two top rods 61.

[0056] S3: Installation device relocation.

[0057] S31: Simultaneously drive the clamping jack 51 and the pushing jack 411 to extend the preset maximum distance, and the pushing jack 411 drives the pushing mechanism 6 to move toward a position away from the center of the installation device.

[0058] S32: The overhead crane moves the installation device to the next top beam 1.

[0059] S33: Repeat steps S2-S32 to complete the installation of the other top beam 1 and shield beam 2, which will not be described in detail here.
