Description

Technical Field

[0001] This invention belongs to the technical field of hydraulic support side guard plate, specifically a fixing device for the side guard plate of a hydraulic support shield beam. Background Technology

[0002] The side guard plate of the hydraulic support shield beam is an important component of the hydraulic support, mainly used to protect the internal structure of the support and the safety of personnel, while preventing external debris from entering the equipment. It is typically installed on the side of the support, effectively blocking coal gangue, gravel, and other debris from falling, ensuring a clean and safe working environment. The side guard plate is made of high-strength steel, possessing excellent wear resistance and impact resistance, and can adapt to the complex underground working environment. Furthermore, the design of the side guard plate takes into account the movement requirements of the hydraulic support, ensuring that it does not interfere with the support during lifting, lowering, and movement.

[0003] In existing technologies, the installation and disassembly of the side guard plates of hydraulic support shield beams are quite cumbersome, requiring significant external force. Operators find it difficult to quickly disassemble the side guard plates, which increases the labor intensity of workers. Furthermore, the current hydraulic support shield beam side guard plates have poor fixing effects. Under frequent movement and vibration of the hydraulic support, the fixing bolts are prone to loosening, causing the side guard plates to shift or fall off, affecting the normal operation of the equipment and hindering the normal operation of the hydraulic support.

[0004] Therefore, we propose a hydraulic support shield beam side guard plate fixing device to solve the problems encountered above. Summary of the Invention

[0027] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1:

[0029] Please see Figure 1 - Figure 5 As shown, a hydraulic support shield beam side guard plate fixing device includes a shield beam body 1, a main plate 2 is provided on the right side of the shield beam body 1, and auxiliary plates 3 are provided on the left and right sides of the main plate 2. A rotating assembly 4 is provided inside the main plate 2. The rotating assembly 4 includes a rotating frame 5. A circular rod 6 is fixedly connected to the lower part of the rotating frame 5. A first receiving plate 7 is fixedly connected to the lower part of the circular rod 6. A connecting block 8 is fixedly connected to the middle position of the lower surface of the first receiving plate 7. A second receiving plate 9 is fixedly connected to the lower part of the connecting block 8. A first rotating shaft 10 is fixedly connected to the middle position of the lower surface of the second receiving plate 9. Two connecting columns 11 are fixedly connected to both sides of the upper surface of the second receiving plate 9.

[0030] The outer surfaces of the two connecting posts 11 are provided with circular rings 12. A connecting rod 13 is fixedly connected to the side of the circular ring 12 away from the connecting block 8. A rotating ring 14 is fixedly connected to the side of the connecting rod 13 away from the second receiving plate 9. A connecting plate 16 is movably connected to the inner wall of the rotating ring 14 through a first pin 15. A fixing plate 17 is fixedly connected to the side of the connecting plate 16 away from the second receiving plate 9. A semi-circular plate 19 is movably connected to the inner side of the fixing plate 17 through a second pin 18. Through the cooperation of the connecting posts 11, circular rings 12, connecting rods 13, rotating rings 14, first pins 15, connecting plates 16 and fixing plates 17, rotation operation can be better performed, so that the control sleeve 23 moves in an arc along the second rotating shaft 22 inside the main board 2, which facilitates the quick disassembly of the sub-plates 3 on both sides of the main board 2.

[0031] A fixing component 20 is fixedly connected to the side of the semi-circular plate 19 away from the second receiving plate 9. The operator can rotate the rotating frame 5, and the rotating component 4 will also rotate counterclockwise or clockwise. Both clockwise and counterclockwise rotation can quickly disassemble the sub-plate 3.

[0032] In the existing technology, the installation and disassembly of the side guard plate of the hydraulic support shield beam are relatively troublesome and require a lot of external force. It is difficult for operators to quickly disassemble the side guard plate of the hydraulic support shield beam, and the disassembly is relatively troublesome, which increases the labor intensity of workers.

[0033] The operator can rotate the rotating frame 5. The first receiving plate 7 and the second receiving plate 9 are set through the second rotating shaft 22, which will cause the left control sleeve 23 to move forward to the right and the right control sleeve 23 to move backward to the left. Then, through the movable connection of the left and right sides of the second receiving plate 9 on the upper surface of the second receiving plate 9, the control sleeve 23 can move in an arc along the second rotating shaft 22, which can quickly remove the sub-plate 3 from both sides of the main plate 2, improve the efficiency of installation and disassembly, and increase practicality.

[0034] The operator can activate the micro cylinder 31 to make the micro cylinder 31 work, causing the limit rod 32 to move upward, so that the limit rod 32 can disengage from the inside of the first clamping plate 27 and the second clamping plate 30. Then the first electric push rod 25 and the second electric push rod 28 can be activated to retract the first drive rod 26 and the second drive rod 29.

[0035] Example 2:

[0036] Please refer to the following: Figure 6 - Figure 8As shown, the fixing assembly 20 includes two control sleeves 23. Limiting plates 21 are fixedly connected to the rear of the left control sleeve 23 and the front of the right control sleeve 23. The lower part of the limiting plates 21 is movably mounted above the inner wall of the main board 2 via a second rotating shaft 22. A square sleeve 24 is fixedly connected to the upper surface of the control sleeve 23. A first electric push rod 25 is disposed at the rear of the inside of the control sleeve 23. A first drive rod 26 is disposed at the power output end of the first electric push rod 25. Two first clamping plates 27 are fixedly connected to the front of the first drive rod 26. A second electric push rod 28 is disposed at the front of the inside of the control sleeve 23. A second drive rod 29 is disposed at the power output end of the second electric push rod 28. A fixed... A second card plate 30 is connected to the inner wall of the square sleeve 24, and a miniature cylinder 31 is provided. The power output end of the miniature cylinder 31 is provided with a limit rod 32. An active button 33 is provided at the front of the lower surface of the square sleeve 24. A limit frame 34 is movably connected to the outer surface of the active button 33. A spring 35 is provided on the upper surface of the active button 33. A trigger plate 36 is provided on the upper surface of the spring 35. A sensor 37 is provided on the upper surface of the trigger plate 36. The sensor 37 can be triggered by the trigger plate 36 or by an external device. When disassembling the sub-plate 3, the operation can be carried out by first starting the miniature cylinder 31 through the external device to retract the limit rod 32, and then starting the first electric push rod 25 and the second electric push rod 28.

[0037] A first limiting block 38 is fixedly connected to the upper part of the sub-plate 3 near the control sleeve 23. A square groove 39 is opened on the upper surface of the first limiting block 38. A first circular groove 40 is opened in front of the first limiting block 38. A box 48 is fixedly connected to the bottom position of the sub-plate 3 away from the main plate 2. A second limiting block 41 is fixedly connected to the front of the first limiting block 38. A slot 42 is opened on the upper part of the second limiting block 41. A second circular groove 43 is opened in front of the second limiting block 41. A third limiting block 44 is fixedly connected to the front of the second limiting block 41. A third circular groove 45 is opened in front of the third limiting block 44. A cooperating groove 46 is opened on the upper surface of the third limiting block 44. A concave-convex block 47 is fixedly connected inside the cooperating groove 46.

[0038] In the current technology, the fixing effect of the side guard plate of the current hydraulic support shield beam is poor. Under the frequent movement and vibration of the hydraulic support, the fixing bolts are easy to loosen, which can cause the side guard plate to shift or fall off, affecting the normal operation of the equipment and hindering the normal operation of the hydraulic support.

[0039] When installing the sub-plate 3, the operator needs to align it with the center position of the control sleeve 23, insert the first limiting block 38, the second limiting block 41, and the third limiting block 44 into the center position inside the control sleeve 23, and then activate the first electric push rod 25 and the second electric push rod 28. Activating the first electric push rod 25 and the second electric push rod 28 will cause the first drive rod 26 and the second drive rod 29 to pass through the first limiting block 38 and the third limiting block 44. This allows the first drive rod 26 to pass through the first circular groove 40 and reach the second circular groove 43 inside the second limiting block 41, and the second drive rod 29 to pass through the third circular groove 45 and reach the second circular groove 43 inside the second limiting block 41. This allows the first locking plate 27 to engage with the second locking plate 28. The plates 30 overlap, and while the third limiting block 44 is inserted into the control sleeve 23, the coordinated groove 46 and the protrusion 47 can compress the active button 33, causing the spring 35 to deform and the trigger plate 36 to move upward, thus touching the sensor 37. The sensor 37 sends a signal to start the micro cylinder 31. The start of the power output end of the micro cylinder 31 will cause the limiting rod 32 to move downward. The limiting rod 32 will be inserted into the first card plate 27 and the second card plate 30 through the slot 42, which can fix the sub-plates 3 on both sides of the main board 2, enhance its fixing effect, facilitate the operator to quickly install and remove the sub-plates 3, and reduce the operator's workload.

[0040] The specific working process of this invention is as follows:

[0041] When installing the sub-plate 3, the operator needs to align it with the center position of the control sleeve 23, insert the first limiting block 38, the second limiting block 41, and the third limiting block 44 into the center position inside the control sleeve 23, and then activate the first electric push rod 25 and the second electric push rod 28. Activating the first electric push rod 25 and the second electric push rod 28 will cause the first drive rod 26 and the second drive rod 29 to pass through the interior of the first limiting block 38 and the third limiting block 44. This allows the first drive rod 26 to pass through the first circular groove 40 and reach the second circular groove 43 inside the second limiting block 41, and the second drive rod 29 to pass through the third circular groove 45 and reach the interior of the second limiting block 41. The first card plate 27 and the second card plate 30 are intersected and overlapped in the second circular groove 43. When the third limiting block 44 is inserted into the control sleeve 23, the setting of the groove 46 and the concave and convex blocks 47 can squeeze the active button 33, thereby causing the spring 35 to deform and the trigger plate 36 to move upward, thereby touching the sensor 37. The sensor 37 sends a signal to start the micro cylinder 31. The start of the power output end of the micro cylinder 31 will cause the limiting rod 32 to move downward. The limiting rod 32 will be inserted into the first card plate 27 and the second card plate 30 through the slot 42, which can fix the sub-plates 3 on both sides of the main board 2.

[0042] Reactivating the micro cylinder 31 causes it to work again, moving the limit rod 32 upwards. This allows the limit rod 32 to disengage from the first clamping plate 27 and the second clamping plate 30. Then, activating the first electric push rod 25 and the second electric push rod 28 causes the first drive rod 26 and the second drive rod 29 to retract. The operator then rotates the rotating frame 5. The first receiving plate 7 and the second receiving plate 9, through the second rotating shaft 22, cause the left control sleeve 23 to move forward to the right and the right control sleeve 23 to move backward to the left. Through the movable connection of the left and right sides of the second receiving plate 9 on the upper surface, the control sleeve 23 moves in an arc along the second rotating shaft 22, allowing the sub-plate 3 to be quickly removed from both sides of the main plate 2.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
