Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic support disassembly and assembly, and particularly relates to an automatic disassembly and assembly line for a hydraulic support. Background Art

[0002] With the continuous advancement of coal mine comprehensive mining technology, coal mining efficiency has been greatly improved. As a key piece of equipment in comprehensive mining working faces, hydraulic supports are being used in increasing numbers and on a larger scale. To ensure efficient operation of comprehensive mining working faces, hydraulic supports require rapid and efficient disassembly, assembly, and maintenance to reduce equipment downtime and improve equipment utilization. Traditional hydraulic support disassembly and assembly are generally completed through the collaboration of workers and lifting equipment. However, existing equipment may not be able to flexibly and widely adjust the height and simultaneously disassemble and assemble parts at different locations, making it difficult to adapt to the disassembly and assembly requirements of hydraulic support parts at different heights. Furthermore, when disassembling and assembling multiple parts at different locations simultaneously, there is a lack of an efficient coordination mechanism, making it impossible to synchronize operations, further reducing disassembly and assembly efficiency. Furthermore, the lifting mechanisms lack the ability to move and work together effectively. The movement of the lifting mechanisms may interfere with each other, making independent and flexible movement difficult, resulting in a limited lifting range. When faced with complex hydraulic support layouts, efficient lifting operations cannot be performed from all angles, reducing overall lifting and disassembly efficiency. Therefore, improvements are needed to address these issues. Summary of the Invention

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail with reference to the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. The technical solutions of the present invention will be described in detail below with reference to the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0020] like Figure 1 As shown in FIG8 , the present invention provides an automated disassembly and assembly line for a hydraulic support, comprising a base 1, a guide rail 3 being provided in the middle of the base 1, a group of columns 2 being provided on the left and right sides of the guide rail 3, each group comprising two columns 2 distributed front to back, an I-beam 4 being fixedly provided between the upper ends of the columns 2 of the same group, two parallel first movable beams 5 and second movable beams 11 being slidably provided between the two I-beams 4, a lifting mechanism being slidably provided on both the first movable beam 5 and the second movable beam 11; a group of lifting mechanisms being provided on the left and right sides of the guide rail 3, the lifting mechanisms being slidably provided on the upper end of the base 1 along the left and right directions; each group of lifting mechanisms comprising two independent front and rear lifting components.

[0021] The guide rail 3 is arranged horizontally along the front-to-back direction. The base 1 is a horizontally arranged square plate-like structure. The two columns 2 in the left group are fixedly arranged at the two left corners of the upper end surface of the base 1, and the two columns 2 in the right group are fixedly arranged at the two right corners of the upper end surface of the base 1. The I-beam 4 is arranged horizontally along the front-to-back direction. The front and rear ends of the lower end surface of the I-beam 4 are respectively fixedly connected to the upper ends of the two columns 2 in the same group. Each I-beam 4 is provided with an upper sliding groove and a lower sliding groove, and the upper and lower sliding grooves are both arranged horizontally along the front-to-back direction.

[0022] The first movable beam 5 is slidably disposed on the I-beams 4 on both sides via a first sliding assembly. The first sliding assembly includes a first motor 9, a first screw 6, a first worm gear 7, a first worm 8, a first movable block 36, and a first universal joint 37.

[0023] A first horizontal screw rod 6 is rotatably installed inside the lower sliding groove of the two I-beams 4. A first movable block 36 is screwed onto each first screw rod 6. The first movable block 36 is a rectangular parallelepiped structure, and the upper and lower end surfaces of the first movable block 36 are in sliding contact with the inner top surface and the inner bottom surface of the lower sliding groove respectively. The first movable beam 5 is arranged horizontally along the left and right directions. The two first movable blocks 36 are respectively located on both sides of the first movable beam 5. A first universal joint 37 is respectively provided at the left and right ends of the first movable beam 5. The first connecting ends of the two first universal joints 37 are respectively fixedly connected to the two first movable blocks 36. The second connecting ends of the two first universal joints 37 are respectively slidably arranged on the left and right end surfaces of the first movable beam 5 along the length direction of the first movable beam 5.

[0024] A first motor 9 is fixedly mounted on the front end of each of the two I-beams 4, and a first worm 8 is fixedly mounted on the output shaft of each of the first motors 9. A first worm gear 7 is fixedly mounted on the front end of each of the two first screw rods 6, and the two first worm gears 8 are meshed with the two first worm gears 7, respectively.

[0025] The two first motors 9 drive the two first worms 8 to rotate, the two first worms 8 drive the two first worm wheels 7 to rotate, and the two first worm wheels 7 drive the two first screw rods 6 to rotate. Since the two first moving blocks 36 are screwed to the two first screw rods 6, the two first moving blocks 36 are driven to move forward or backward synchronously, thereby driving the first moving beam 5 forward or backward. Since the two ends of the first moving beam 5 are connected to the first moving blocks 36 on both sides through the first universal joints 37, and the first moving beam 5 maintains a sliding connection with the first universal joints 37 on both sides, when there is a height difference between the two first screw rods 6 or the front and rear positions of the two first moving blocks 36 deviate, the two first universal joints 37 can slide at the two ends of the first moving beam 5, thereby ensuring that the first moving blocks 36 on both sides can still drive the first moving beam 5 to slide back and forth.

[0026] The second movable beam 11 is slidably mounted on the I-beam 4 on both sides via a second sliding assembly. The second sliding assembly includes a second motor 15, a second screw 12, a second worm gear 13, a second worm 14, a second movable block 38, and a second universal joint 39.

[0027] A second horizontal screw rod 12 is arranged in the upper side sliding groove of each of the two I-beams 4, and a second moving block 38 is screwed on each second horizontal screw rod 12. The second moving block 38 is a cuboid structure, and the upper and lower end faces of the second moving block 38 are in sliding contact with the inner top face and the inner bottom face of the upper side sliding groove, respectively. The second moving beam 11 is in an inverted U-shaped structure, and the middle part of the second moving beam 11 protrudes upward. The middle part of the second moving beam 11 is horizontally arranged along the left-right direction, and the two second moving blocks 38 are located on the left and right sides of the second moving beam 11, respectively. A second universal joint 39 is arranged at each of the left and right ends of the second moving beam 11, and the first connecting end of each second universal joint 39 is fixedly connected with the second moving block 38, and the second connecting end of each second universal joint 39 is slidingly arranged on the left or right end face of the second moving beam 11 along the length direction of the second moving beam 11.

[0028] A second motor 15 is fixedly arranged at the rear end of each of the two I-beams 4, and a second worm 14 is fixedly arranged on the output shaft of each second motor 15. A second worm wheel 13 is fixedly arranged at the rear end of each of the two second screw rods 12, and the two second worms 14 are in engagement with the two second worm wheels 13, respectively.

[0029] The two second motors 15 drive the two second worms 14 to rotate, the two second worms 14 drive the two second worm wheels 13 to rotate, and the two second worm wheels 13 drive the two second screw rods 12 to rotate. Since the two second moving blocks 38 are screwed on the two second screw rods 12, the two second moving blocks 38 are driven to move forward or backward synchronously, and the second moving beam 11 is driven to move forward or backward. Since the two ends of the second moving beam 11 are connected with the second moving blocks 38 on the left and right sides through the second universal joints 39, and the second moving beam 11 is in sliding connection with the second universal joints 39 on the left and right sides, when there is a height difference between the two second screw rods 12 or the front and back positions of the two second moving blocks 38 are deviated, the two second universal joints 39 can slide at the two ends of the second moving beam 11, so that the second moving blocks 38 on the left and right sides can still drive the second moving beam 11 to slide forward or backward.

[0030] A first horizontal sliding rail 10 is fixedly arranged at the lower end of the first moving beam 5, and a second horizontal sliding rail 16 is fixedly arranged at the lower end of the second moving beam 11. The hoisting mechanism is slidingly arranged on the first sliding rail 10 and the second sliding rail 16. The hoisting mechanism comprises a winding box 17, a positioning block 18, a screw rod 19, a positioning plate 20, a pulley 21, a driven gear 22, a driving gear 23, a power supply 24, a third motor 25, a fourth motor 26, a wire cable 27, and a hand-operated hoist 28.

[0031] The winding box 17 is a square box structure with an open bottom. A positioning block 18 is fixedly mounted at its top. Positioning plates 20 are located on either side of the positioning block 18. These positioning plates 20 are square plate-like structures located in a vertical plane. Two horizontal screws 19 extend through the positioning block 18 and the two positioning plates 20. A locking nut is screwed onto each end of each screw 19, connecting the positioning block 18 to the two positioning plates 20. Two symmetrical pulleys 21 are rotatably mounted on the upper ends of the adjacent end surfaces of the two positioning plates 20. A third motor 25 is fixedly mounted on the outer side of the front positioning plate 20. The output shaft of the third motor 25 extends into the inner side of the front positioning plate 20. A drive gear 23 is fixed to the output shaft of the third motor 25. A driven gear 22 is fixed to each of the two pulleys 21 on the front positioning plate 20, and the drive gear 23 is meshed with the two driven gears 22. A power supply 24 is fixedly mounted on the outer side of the rear positioning plate 20 .

[0032] A winding roller is rotatably mounted within the winding box 17. A fourth motor 26 is fixedly mounted on the outer side of the winding box 17. The output shaft of the fourth motor 26 is fixedly connected to the end of the winding roller, driving the winding roller to rotate. A cable 27 is fixedly wound around the outer side of the winding roller, with the end of the cable 27, away from the winding roller, fixed to the outer side of the winding box 17. A hand chain hoist 28 is mounted on the cable 27.

[0033] The power supply 24 is electrically connected to the third motor 25 and the fourth motor 26 .

[0034] Two positioning plates 20 within the lifting mechanism are located on the front and rear sides of the first or second rail 10, 16, respectively. Pulleys 21 on the two positioning plates 20 are respectively rotatably mounted on the front and rear sides of the upper end surface of the first or second rail 10, 16. A third motor 25 rotates a drive gear 23, which in turn rotates two driven gears 22. These driven gears 22 rotate the two pulleys 21 on the front positioning plate 20. The two pulleys 21 roll on the upper end surface of the first or second rail 10, 16, thereby enabling the lifting mechanism to slide on the first or second rail 10, 16.

[0035] The lifting mechanism further comprises a moving seat 29 which is a square box structure with an open upper end, and two groups of front and rear rollers 30 are arranged on the lower end surface of the moving seat 29 and are arranged to roll on the upper end of the base 1. A plurality of first hydraulic cylinders 31 are arranged on the side of the moving seat 29 away from the guide rail 3, and the plurality of first hydraulic cylinders 31 are arranged in the front and rear directions, the cylinder body of the first hydraulic cylinder 31 is fixedly arranged on the upper end of the base 1, and one end of the telescopic rod of the first hydraulic cylinder 31 is fixedly connected to the side of the moving seat 29. The synchronous extension and retraction of the plurality of first hydraulic cylinders 31 drives the left and right movement of the lifting mechanism.

[0036] The lifting assembly comprises a second hydraulic cylinder 35, a lifting frame 32 and a lifting table 33. Two waist-shaped grooves are arranged in the middle of the side walls on the left and right sides of the moving seat 29, and the length direction of the waist-shaped grooves is arranged horizontally along the front and rear directions. The same left and right horizontal sliding rod is slidingly inserted into the two waist-shaped grooves on the front side, and the same left and right horizontal sliding rod is slidingly inserted into the two waist-shaped grooves on the rear side. One second hydraulic cylinder 35 is rotatably arranged in the middle of the inner wall on the front and rear sides of the moving seat 29, the piston rod of the second hydraulic cylinder 35 on the front side is connected to the middle of the sliding rod on the front side, and the piston rod of the second hydraulic cylinder 35 on the rear side is connected to the middle of the sliding rod on the rear side. Each lifting assembly comprises two left and right symmetrical lifting frames 32, and the same lifting table 33 is rotatably arranged on the upper end of the two lifting frames 32, and the lower end of the two lifting frames 32 is connected to the moving seat 29.

[0037] The lifting frame 32 is formed by mutually hingedly connecting a plurality of X-shaped frames, the center of the X-shaped frame is hingedly connected, and the lower side of the upper X-shaped frame is hingedly connected to the upper side of the lower X-shaped frame. The upper side of the uppermost X-shaped frame is hingedly connected to the lower end surface of the lifting table 33, one end of the lower side of the lowermost X-shaped frame is hingedly connected to the inner wall of the moving seat 29, and the other end of the lower side of the lowermost X-shaped frame is hingedly connected to the sliding rod on the same side.

[0038] The lifting table 33 is a horizontally arranged square plate structure, and a guardrail 34 is fixedly arranged on the side of each lifting table 33 away from the guide rail 3 and away from the other lifting assembly.

[0039] The synchronous extension and retraction of the two second hydraulic cylinders 35 in the moving seat 29 can control the synchronous lifting of the two lifting tables 33, and the independent extension and retraction of the two second hydraulic cylinders 35 in the moving seat 29 can control the independent lifting of the two lifting tables 33.

[0040] The application also provides a use method of the hydraulic support automatic disassembly and assembly line, which comprises the following steps: Step 1, first connect all electrical equipment to the wires and power on; when the hydraulic support needs to be disassembled and assembled, the hydraulic support is placed on the mobile trolley, and then the mobile trolley is moved to the base 1 through the guide rail 3, and then the disassembler is asked to stand on the lifting platform 33 and connect the protective device on the body to the guardrail 34; then the second hydraulic cylinder 35 is started to control the lifting frame 32 to rise, and the disassembler is moved to a height convenient for disassembly and assembly; then according to the size of the hydraulic support, the distance between the lifting platform 33 and the hydraulic support is adjusted, and the first hydraulic cylinder 31 is started, and the movement of the lifting platform 33 is controlled by the roller 30, and then the disassembler is moved to a distance convenient for disassembly and assembly; when two parts that are far apart need to be disassembled and assembled at the same time during the disassembly and assembly process, the two second hydraulic cylinders 35 inside the mobile seat 29 are controlled to start respectively, and then the two lifting platforms 33 are controlled to rise to different heights, thereby facilitating subsequent disassembly and assembly.

[0041] Step 2: During disassembly and assembly, some parts are large and difficult for the disassembly personnel to control. In this case, the lifting mechanism needs to be controlled to move to the position to assist the disassembly personnel in disassembly. First, the first movable beam 5 is controlled to move, and the two first motors 9 are started. The two first motors 9 drive the two first worms 8 to rotate, and the two first worms 8 drive the two first worm wheels 7 to rotate. The two first worm wheels 7 drive the two first screw rods 6 to rotate. Since the two first movable blocks 36 are screwed to the two first screw rods 6, the two first movable blocks 36 are driven to move forward or backward synchronously, thereby driving the first movable beam 5 forward or backward.

[0042] Step 3: After the first moving beam 5 moves to the designated position, the third motor 25 inside the lifting mechanism on the first moving beam 5 is started. The third motor 25 drives the driving gear 23 to rotate, which in turn drives the two driven gears 22 to rotate. The two driven gears 22 drive the two pulleys 21 on the front positioning plate 20 to rotate. The two pulleys 21 roll on the upper end surface of the first slide rail 10, thereby enabling the lifting mechanism to slide on the first slide rail 10. When the hand chain hoist 28 moves to the designated position, the hand chain hoist 28 is connected to the component, and the fourth motor 26 is controlled to rotate in the opposite direction to suspend the component in the air.

[0043] Step 4: When the first movable beam 5 needs to be disassembled and assembled during use, the two second motors 15 are started. The two second motors 15 drive the two second worms 14 to rotate, the two second worms 14 drive the two second worm wheels 13 to rotate, and the two second worm wheels 13 drive the two second screw rods 12 to rotate. Since the two second movable blocks 38 are screwed together with the two second screw rods 12, the two second movable blocks 38 are driven to move forward or backward synchronously, thereby driving the second movable beam 11 forward or backward. Since the second movable beam 11 and the first movable beam 5 are staggered in an up-and-down manner and the second movable beam 11 is an inverted U-shaped structure, the first movable beam 5 and the second movable beam 11 will not interfere with each other during the sliding process.

[0044] Step 5: After the second movable beam 11 has moved to the designated position, the third motor 25 inside the lifting mechanism on the second movable beam 11 is started. The third motor 25 drives the driving gear 23 to rotate, which in turn drives the two driven gears 22 to rotate. The two driven gears 22 drive the two pulleys 21 on the front positioning plate 20 to rotate. The two pulleys 21 roll on the upper end surface of the second slide rail 16, thereby enabling the lifting mechanism to slide on the second slide rail 16. When the hand chain hoist 28 has moved to the designated position, the hand chain hoist 28 is connected to the component, and the fourth motor 26 is controlled to rotate in the opposite direction to suspend the component in the air.
