Description

Technical Field

[0001] This invention relates to the field of coal mine fully mechanized mining equipment assembly technology, and in particular to a hydraulic support assembly platform. Background Technology

[0002] Hydraulic supports are the core support equipment for fully mechanized coal mining faces, and their operational stability directly determines the mining safety and production efficiency of the face. The top beam, as the core load-bearing component of the hydraulic support, is characterized by its large size and high weight. Furthermore, the top beam integrates numerous precision components such as hydraulic valve groups and high-pressure pipelines. During assembly, extremely stringent requirements are placed on the stability of hoisting operations and the safety of tilting operations.

[0003] Currently, conventional technical solutions for hoisting and rotating hydraulic support beams generally rely on overhead cranes to achieve horizontal movement of the hoisting mechanism. They also require independent hoisting and rotating mechanisms to perform vertical hoisting and tilting of the beam, respectively. This traditional approach not only requires multiple pieces of equipment but also often relies on manual assistance with chain hoists for tilting, resulting in a heavy workload for workers, low tilting efficiency, and the risk of chain hoists breaking under prolonged stress, posing significant safety hazards. This type of solution requires laying overhead crane tracks and installing complex electrical control systems at the work site, resulting in a large overall equipment structure, extremely high disassembly and transportation difficulties, and high equipment investment and maintenance costs. Furthermore, the overhead crane is prone to swaying and insufficient positioning accuracy during operation, failing to meet the precise alignment requirements of the beam hoisting points.

[0004] Furthermore, existing hydraulic support top beam hoisting and tilting equipment cannot achieve a high degree of integration of the three core functions of horizontal displacement, vertical lifting, and attitude tilting. The dispersed functions result in high equipment redundancy and complex control logic, making it impossible to balance operational safety, space utilization, equipment cost, and ease of maintenance. Consequently, it is difficult to meet the needs of efficient, safe, and low-cost assembly and maintenance of hydraulic supports in underground mines.

[0005] Therefore, there is an urgent need for a highly integrated hydraulic support assembly platform that can be adapted to vertical lifting and horizontal tilting functions. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention proposes a hydraulic support assembly platform that has the functional advantages of being adaptable to vertical lifting and horizontal rotation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A hydraulic support assembly platform includes a rope and a winding mechanism. The platform further includes a support frame slidably connected to the winding mechanism. The winding mechanism includes a housing. Inside the housing is a drive wheel that is frictionally connected to the rope. When the drive wheel rotates, it drives the rope to rotate. A drive motor is located on one side of the drive wheel to achieve the rotation of the drive wheel. A guide wheel, rotatably connected to the housing, is located below the drive wheel. The guide wheel engages with the rope through rolling friction. Friction anti-reverse components are located on one side of both the guide wheel and the drive wheel to limit the relative movement between the rope, the guide wheel, and the drive wheel. A limit wheel is located inside the rope, between the guide wheel and the drive wheel. A horizontal displacement mechanism is located on one side of the limit wheel.

[0008] Preferably, the friction anti-reverse component includes a cooperating wheel rotatably connected to the housing. The cooperating wheel is provided with a plurality of protrusions, and the guide wheel and the drive wheel are provided with corresponding grooves for the protrusions. The rope is located between the protrusions and the grooves. A limit component is provided on one side of the cooperating wheel, and the limit component is used to control the rotation of the cooperating wheel.

[0009] Preferably, the limiting component includes a synchronous shaft connected to the cooperating wheel key, a limiting gear is connected to the axial end of the synchronous shaft by a key, and a limiting block is provided on one side of the limiting gear. A limiting groove is formed on the limiting block for the teeth of the limiting gear. A linear drive component is provided on one side of the limiting block. Under the action of the linear drive component, the limiting block moves linearly relative to the housing along the central axial direction of the synchronous shaft.

[0010] Preferably, the linear drive component includes a piston cylinder, a piston rod is slidably connected in the inner cavity of the piston cylinder, and the piston rod is elastically slidably connected to the limiting block. When the piston cylinder is not affected by external force, the limiting block and the corresponding limiting gear are not in the same vertical plane. A dual-purpose air pump is provided inside the housing, and the external interface of the dual-purpose air pump is connected to the inner cavity of the piston cylinder through a connecting pipe.

[0011] Preferably, the drive wheel side end is provided with two sets of friction anti-reverse components for the two guide wheels respectively, and the two friction anti-reverse components on the same side share a common air pump. The outer end of the rope is provided with a contact switch, which is located between the guide wheel and the drive wheel. When the limit wheel moves away from the housing relative to the housing, the contact switch is triggered. The contact switch is electrically connected to the air pump on the same side. When a single contact switch is triggered, the piston rod on the corresponding side extends. When both contact switches are triggered, both piston rods retract.

[0012] Preferably, a control assembly is provided between the two piston cylinders corresponding to the drive wheel and between the two piston cylinders corresponding to the two guide wheels. The control assembly includes an energy storage tube. The inner cavity of the energy storage tube is connected to the piston cylinders on both sides through two synchronization tubes. Furthermore, a normally closed control valve is provided between the two synchronization tubes. When the control valve detects an increase in pressure in the inner cavity of the synchronization tubes on both sides, the control valve opens.

[0013] Preferably, the control valve includes a conical block with vertical axial direction and communicating with the energy storage tube. A through hole is opened at the center of the conical block, and a one-way valve is installed in the through hole. A compression spring is coaxially installed on the conical block. The two axial ends of the compression spring abut against the inner cavity of the energy storage tube and the conical block, respectively. Two support blocks with trapezoidal vertical projections and whose hypotenuses abut against the conical block are provided on the side of the conical block near the synchronization tube. An unlocking component is provided on one side of each support block. When the pressure in the inner cavity of the corresponding synchronization tube increases, the corresponding unlocking component controls the trapezoidal block to move away from the conical block.

[0014] Preferably, the unlocking component includes a positioning block located in the inner cavity of the synchronizing tube and fixedly connected to the synchronizing tube. A driven block that is slidably connected to the synchronizing tube is provided on the side of the positioning block near the corresponding piston cylinder. The driven block is fixedly connected to the corresponding trapezoidal block, and a return spring is provided between the driven block and the positioning block.

[0015] Preferably, the horizontal displacement mechanism includes a winch fixedly connected to the support frame and a recovery mechanism disposed inside the housing, wherein the movable end of the winch and the movable end of the corresponding recovery mechanism are respectively fixedly connected to a limit wheel.

[0016] Preferably, the rope includes a normal belt wrapped around the outside of the drive wheel and a movable belt detachably connected to the normal belt via a hook.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention replaces the overhead crane in traditional solutions with a fixed support frame that slides with the winding mechanism, significantly reducing the difficulty of installation, transportation, and maintenance, and substantially compressing the overall investment cost. It also completely avoids the swaying problem during crane movement, improving the accuracy of hoisting point alignment and operational stability. Through differentiated collaborative control of the limit wheels and the horizontal displacement mechanism, the invention integrates the two core functions of horizontal displacement of the winding mechanism and vertical lifting of the top beam onto the same set of actuators, greatly simplifying the overall structure and improving functional integration. Combined with a connectable ring-shaped rope tilting structure, the top beam can be tilted at all angles without high-altitude hoisting, significantly reducing the vertical space required for tilting operations and perfectly adapting to the space-constrained working scenarios of underground coal mine roadways.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Please refer to Figure 1-11 This is a hydraulic support assembly platform, mainly used in the assembly and maintenance of hydraulic supports in underground coal mines, especially suitable for the hoisting, position adjustment, and tilting of hydraulic support top beams. As the core support equipment in fully mechanized mining faces, hydraulic supports have a large volume and considerable weight in their top beam structure, which integrates a large number of precision components such as hydraulic valve groups and pipelines. During assembly and maintenance, extremely high requirements are placed on the stability of hoisting, the safety of tilting, and the efficiency of space utilization.

[0033] Please refer to Figure 1 In existing technologies, the hoisting and tilting operations of hydraulic support beams typically require an overhead crane to achieve the horizontal movement of the winding mechanism 4, while independent hoisting and tilting mechanisms are needed to complete the vertical hoisting and beam tilting functions respectively. The overall equipment structure is large, installation and maintenance are difficult, and costs are high. At the same time, the traditional overhead crane tilting method has strict space requirements. For example, if the length of the hydraulic support beam is greater than 9.3 meters and the support height is more than 8 meters, the height of the plant and the overhead crane needs to be greater than 13 meters, which will significantly increase the infrastructure costs.

[0034] Please refer to Figure 1 , Figure 2 Consistent with existing technology, the hoisting equipment includes a rope 1 and a winding mechanism 4. The upper end of the rope 1 is connected to the winding mechanism 4, which can drive the rope 1 to wind up and down and lock its position. At the same time, it works with the rope 1 to complete the vertical lifting, horizontal position adjustment and flipping operations of the top beam.

[0035] Unlike existing technologies, this device includes a support frame 2 that is slidably connected to the winding mechanism 4. The support frame 2 serves as the overall installation reference for this device and employs a fixed frame structure. This replaces the overhead crane used in existing technologies to drive the horizontal movement of the winding mechanism 4, eliminating the need for overhead crane track laying and complex electrical system installation. This significantly reduces installation difficulty, maintenance costs, and overall investment, while also avoiding problems such as swaying and insufficient positioning accuracy during overhead crane operations, thus improving the stability of hoisting operations.

[0036] Please refer to Figure 2 , Figure 3 , Figure 4 Specifically, the winding mechanism 4 includes a housing 41, which serves as the mounting carrier for all internal components of the winding mechanism 4, providing stable mounting support and protection for internal components such as the drive wheel 43, guide wheel 45, friction anti-reverse component 46, and limit wheel 44. Based on this, the housing 41 and the support frame 2 are connected by a sliding connection.

[0037] In addition, a sliding guide rail extending horizontally is provided on the support frame 2, and a sliding mating part that cooperates with the sliding guide rail is provided on the top of the housing 41, so that the entire winding mechanism 4 can slide linearly along the horizontal guide rail of the support frame 2, thereby realizing the overall horizontal position adjustment of the winding mechanism 4, and thus driving the hoisting top beam to complete the precise adjustment of the horizontal position.

[0038] Correspondingly, the housing 41 is provided with a drive wheel 43 that is frictionally connected to the rope 1. The two ends of the drive wheel 43 are rotatably connected to the inner wall of the housing 41 through bearings.

[0039] Meanwhile, a drive motor 42 is provided on one side of the drive wheel 43. The output shaft of the drive motor 42 is connected to the axial end of the drive wheel 43, which can drive the drive wheel 43 to rotate in the forward or reverse direction around its own axis. The drive wheel 43 and the rope 1 are connected by friction. When the drive wheel 43 rotates under the drive of the drive motor 42, the friction between the drive wheel 43 and the rope 1 can drive the rope 1 to rotate in a cycle. In turn, the rotation of the rope 1 drives the top beam sleeved on the inner side of the rope 1 to complete the flipping operation. The rope belt 1 flipping method used in this embodiment does not require lifting one end of the top beam for large-angle flipping. The top beam is simply covered with a ring rope belt 1. The top beam itself forms a strong frictional fit between the rope belt 1 and the top beam by its own weight. The flipping operation is completed by driving the rope belt 1 to rotate through the drive wheel 43. This greatly reduces the vertical space required for the flipping operation and avoids unnecessary waste of on-site space. At the same time, it can prevent valve pipes and precision components on the top beam from being damaged by heavy pressure or collision during the flipping process. It is suitable for the operation requirements of the valve pipes on the top beam being installed with the installation surface facing upwards and then flipping after installation.

[0040] A guide wheel 45 is provided on the lower side of the drive wheel 43 and is rotatably connected to the housing 41. The two ends of the guide wheel 45 are also rotatably connected to the inner wall of the housing 41 through bearings. The guide wheel 45 and the rope 1 are in rolling friction cooperation to guide and limit the direction of the rope 1, ensuring that the rope 1 runs stably under the drive of the drive wheel 43 and effectively avoiding the problem of the rope 1 running off track or derailing.

[0041] It should be noted that a friction anti-slip member 46 is provided on one side of both the guide wheel 45 and the drive wheel 43. The friction anti-slip member 46 is used to limit the relative sliding between the rope 1 and the guide wheel 45 and the drive wheel 43. The friction anti-slip component 46 has two core functions: First, during the rotation of the drive wheel 43 driving the rope 1, the friction anti-slip component 46 can cooperate with the drive wheel 43 to further enhance the frictional force between the drive wheel 43, the guide wheel 45 and the rope 1, ensuring that there is no relative slippage between the drive wheel 43 and the rope 1, and ensuring that the rotational power of the drive wheel 43 can be stably and efficiently transmitted to the rope 1, realizing the stable cyclic rotation of the rope 1, thereby ensuring the reliability of the top beam overturning operation; Second, the friction anti-slip component 46 can achieve position locking of the shell 41 through active control, so that the rope 1 that abuts against the drive wheel 43 and the guide wheel 45 cannot move relative to each other, thereby ensuring the stability of the hoisting position of the rope 1 during the horizontal adjustment of the top beam, and preventing the rope 1 from slipping or the hoisting height from changing, thus improving the safety of the hoisting operation.

[0042] Please refer to Figure 4 , Figure 5 , Figure 6 Specifically, in order to achieve vertical lifting and horizontal position adjustment of the shell 41, two limit wheels 44 are respectively provided on the inner side of the rope 1. Both limit wheels 44 are located between the guide wheel 45 and the drive wheel 43, and a set of horizontal displacement mechanism 3 is provided on one side of each limit wheel 44.

[0043] The upper end of the rope 1 is U-shaped and sleeved on the outside of the drive wheel 43. The two vertical sections extend downward and pass under the guide wheel 45 to form two free ends. The two limiting wheels 44 respectively abut against the inner sides of the left and right vertical sections of the rope 1. The wheel surface is in close contact with the inner side of the rope 1. It can not only provide limiting and tensioning for the vertical sections, but also change the shape and hoisting height of the rope 1 by its own horizontal movement, and can also drive the winding mechanism 4 to move horizontally as a whole.

[0044] In the initial state, both limiting wheels 44 are close to the central axis of the housing 41, the two vertical sections of the rope 1 are vertical, the lower hoisting end is at its lowest initial height, and the winding mechanism 4 is locked in place. Through differentiated control of the horizontal displacement mechanisms 3 on both sides, this device can achieve two core motion states, as follows: The first motion state is that the unilateral horizontal displacement mechanism 3 works, and the other horizontal displacement mechanism 3 releases the limiting wheel 44 on the corresponding side, realizing the overall horizontal position adjustment of the winding mechanism 4. When it is necessary to adjust the horizontal position of the winding mechanism 4 to adapt to different lifting holes on the top beam, the operator only needs to start the unilateral horizontal displacement mechanism 3, and the other side remains in a non-working state and releases the corresponding limiting wheel 44, so that it can move freely with the change of the shape of the rope belt 1. At this time, the horizontal displacement mechanism 3 in the working state will drive the corresponding limiting wheel 44 to move horizontally along the direction away from the central axis of the housing 41. Since the friction anti-backward component 46 on this side has locked the relative movement of the rope belt 1 with the driving wheel 43 and the guiding wheel 45, the rope belt 1 cannot slip between the two. Therefore, when the limiting wheel 44 moves outward, it will apply a horizontal pulling force to the housing 41 through the rope belt 1. This pulling force can overcome the sliding resistance between the housing 41 and the support frame 2, and pull the entire winding mechanism 4 to move horizontally along the horizontal guide rail of the support frame 2 in the direction opposite to the moving direction of the limiting wheel 44, thereby realizing the precise adjustment of the overall horizontal position of the winding mechanism 4. This solution does not require the configuration of a crane traveling drive mechanism and an electrical control system. Only through the horizontal movement of the unilateral limiting wheel 44 can the overall horizontal displacement of the winding mechanism 4 be realized, greatly simplifying the equipment structure and reducing the cost. At the same time, the horizontal movement positioning accuracy is higher, the operation is more stable, and the shaking problem during the crane traveling is completely avoided.

[0045] The second motion state is that the bilateral horizontal displacement mechanisms 3 work simultaneously to realize the vertical lifting of the top beam. When it is necessary to perform a vertical lifting operation on the top beam, the operator starts the horizontal displacement mechanisms 3 on both sides at the same time. The horizontal displacement mechanisms 3 on both sides respectively drive the corresponding two limiting wheels 44 to move horizontally towards positions away from the central axis of the housing 41 and with opposite moving directions, that is, the left limiting wheel 44 moves horizontally to the left, and the right limiting wheel 44 moves horizontally to the right, and the two limiting wheels 44 move outward synchronously. At this time, the pulling forces applied by the two limiting wheels 44 to the housing 41 are equal in magnitude and opposite in direction, and the two cancel each other out. Therefore, the housing 41 will not generate horizontal displacement, and the entire winding mechanism 4 can maintain its position fixed. During the process of the two limiting wheels 44 moving outward synchronously, they will push the two vertical segments of the rope belt 1 to spread outward, making the part of the rope belt 1 between the guiding wheel 45 and the driving wheel 43 form a "middle" - shaped morphological structure. Under the spreading action of the two limiting wheels 44, the rope belt 1 bulges outwards from the housing 41. The more the part of the rope belt 1 that bulges out of the housing 41, the higher the height of the position where its lower side cooperates with the lifting hole of the top beam. In this way, through the synchronous outward movement of the two limiting wheels 44, the height of the lifting end of the rope belt 1 can be increased, and then the top beam hung on the lower side of the rope belt 1 can be lifted vertically to complete the vertical lifting operation. This solution integrates the horizontal position adjustment and vertical lifting functions into the same set of limiting wheels 44 and horizontal displacement mechanisms 3, greatly improving the functional integration degree of the equipment, eliminating the setting of independent mechanisms, further simplifying the equipment structure, and reducing the equipment cost and failure rate.

[0046] Please refer to Figure 8 , Figure 8 Specifically, the friction anti-reverse component 46 includes a cooperating wheel 465 rotatably connected to the housing 41. The two ends of the cooperating wheel 465 are rotatably connected to the inner wall of the housing 41 through bearings. Several protrusions 466 are evenly arranged in the circumferential direction on its outer circumferential surface. Correspondingly, the guide wheel 45 and the drive wheel 43 are provided with matching grooves 467 on their outer circumferential surfaces for the protrusions 466. The shape and size of the grooves 467 are completely matched with the protrusions 466. The rope 1 is clamped between the protrusions 466 and the grooves 467. When the cooperating wheel 465 is not restricted by external force and can rotate freely, the protrusion 466 on the cooperating wheel 465 will pass through the rope 1 and embed into the corresponding groove 467 of the drive wheel 43 or guide wheel 45. Through the interlocking effect between the protrusion 466 and the groove 467, the rope 1 is tightly pressed against the wheel surface of the drive wheel 43 and the guide wheel 45, so that the abutting part of the drive wheel 43, the guide wheel 45, the cooperating wheel 465 and the rope 1 cannot slide relative to each other, thus forming a very strong frictional locking effect. At this time, when the drive motor 42 drives the drive wheel 43 to rotate, the drive wheel 43 will drive the cooperating wheel 465 to rotate synchronously through the engagement of the protrusion 466 and the groove 467. At the same time, the strong friction will drive the rope 1 to rotate stably, completely avoiding the problem of slippage between the drive wheel 43 and the rope 1, ensuring the synchronicity and stability of the rotation of the rope 1. This ensures that during the top beam flipping operation, the rope 1 can accurately drive the top beam to complete the flipping, and there will be no safety hazards such as the top beam falling due to the deviation of the flipping angle or the slippage of the rope 1.

[0047] In addition, a limit component 461 is provided on one side of the cooperating wheel 465. The limit component 461 is used to control the rotation state of the cooperating wheel 465, that is, to control the cooperating wheel 465 to switch between a freely rotating state and a locked and non-rotating state, thereby realizing the switching of the two functions of the friction anti-reverse component 46.

[0048] Correspondingly, when the cooperating wheel 465 is locked by the limiting component 461 and cannot rotate, the drive motor 42 does not work. Through the engagement and locking of the protrusion 466 and the groove 467, it can be ensured that the rope 1 cannot slide relative to the drive wheel 43 and the guide wheel 45, thereby achieving absolute position locking of the rope 1. In this way, during the adjustment of the horizontal position of the top beam, it is ensured that the hoisting of the rope 1 will not protrude significantly from the shell 41.

[0049] Specifically, the limiting component 461 includes a synchronous shaft 4613 keyed to the cooperating wheel 465. The synchronous shaft 4613 and the cooperating wheel 465 are coaxially arranged. One end of the synchronous shaft 4613 is fixedly connected to the axial end of the cooperating wheel 465 by a flat key, so that the synchronous shaft 4613 can rotate synchronously with the cooperating wheel 465. The other end of the synchronous shaft 4613 extends to the inner wall of the housing 41 and is rotatably connected to the housing 41 by a bearing, ensuring that the synchronous shaft 4613 and the cooperating wheel 465 can rotate stably. The axial end of the synchronous shaft 4613 away from the cooperating wheel 465 is keyed to a limiting gear 4614. This gear is coaxially arranged with the synchronous shaft 4613 and the cooperating wheel 465 and can rotate completely synchronously with the cooperating wheel 465. A limiting block 4612 is provided on one side of the limiting gear 4614. A limiting groove is provided on the limiting block 4612 corresponding to the teeth of the limiting gear 4614. Its shape and size are adapted to the teeth and can form a meshing engagement with the teeth of the limiting gear 4614.

[0050] When the limiting block 4612 is driven to move by the linear drive component 4611, causing the teeth of the limiting gear 4614 to engage in the limiting groove of the limiting block 4612, the limiting block 4612 cannot rotate. The two will restrict the rotation of the limiting gear 4614 through the meshing of the limiting groove and the teeth, and then restrict the rotation of the cooperating wheel 465 through the synchronous shaft 4613, thus locking it and realizing the locking function of the friction anti-reverse component 46 on the rope 1. Correspondingly, when the limiting block 4612 is driven to move in the opposite direction by the linear drive component 4611, causing the teeth of the limiting gear 4614 to disengage from the limiting groove and the two to disengage, the limiting gear 4614, the synchronous shaft 4613, and the cooperating wheel 465 can rotate freely. At this time, the friction anti-reverse component 46 switches to the state of cooperating with the drive wheel 43 to drive the rope 1 to rotate, which can ensure the strong friction transmission effect between the drive wheel 43 and the rope 1.

[0051] A linear drive component 4611 is provided on one side of the limiting block 4612. Under the action of its driving force, the limiting block 4612 can move linearly relative to the housing 41 along the central axis of the synchronous shaft 4613, thereby realizing engagement and disengagement with the limiting gear 4614 and completing the switching of the rotation state of the cooperating wheel 465.

[0052] Specifically, the linear drive component 4611 includes a piston cylinder 46111, which is fixedly mounted on the inner wall of the housing 41. A piston rod 46112 is slidably connected to its inner cavity (a polygonal rod can be used to achieve the slidable connection, which can effectively prevent the piston rod 46112 from rotating relative to the piston cylinder 46111). The extended end of the piston rod 46112 is set towards the limiting gear 4614 and is elastically slidably connected to the limiting block 4612. The elastic sliding connection is designed primarily to prevent travel conflict between the limit block 4612 and the limit gear 4614. Specifically, when the linear drive component 4611 drives the limit block 4612 towards the limit gear 4614, misalignment may occur between the limit groove and the teeth of the limit gear 4614. If a rigid connection is used in this situation, a rigid collision between the limit block 4612 and the teeth of the limit gear 4614 would occur, causing tooth damage and equipment malfunction. The elastic sliding connection, however, can accumulate elastic potential energy through the elastic element, allowing the limit block 4612 to maintain contact with the tooth surface of the limit gear 4614 without rigid collision. When the cooperating wheel 465 drives the limit gear 4614 to rotate to the position where the teeth align with the limit groove, the elastic element releases its elastic potential energy, pushing the limit block 4612 to move, causing the teeth to engage in the limit groove and complete the locking mechanism. This ensures the reliability and stability of the limit component 461 and prevents damage to equipment components.

[0053] Specifically, the structure of the elastic sliding connection can be configured as follows: the extended end of the piston rod 46112 is provided with a sliding cavity, one end of the limiting block 4612 is slidably connected in the sliding cavity, and a compression elastic element (such as a corresponding spring) is provided in the sliding cavity. The two ends of the compression elastic element abut against the inner wall of the sliding cavity and the end of the limiting block 4612, respectively, so that the limiting block 4612 can elastically slide relative to the piston rod 46112 for a certain stroke. When the teeth of the limiting block 4612 and the limiting gear 4614 are not aligned, the limiting block 4612 will compress the compression elastic element and retract in the sliding cavity to accumulate elastic potential energy; when the teeth are aligned with the limiting groove, the compression elastic element releases the potential energy, pushing the limiting block 4612 to extend and complete the engagement and locking.

[0054] In the initial state, when the piston cylinder 46111 is not subjected to external force, the piston rod 46112 is fully retracted. At this time, the limiting block 4612 and the corresponding limiting gear 4614 are not in the same vertical plane and there is no contact between them. The cooperating wheel 465 can rotate freely without being restricted by the limiting component 461, ensuring that the drive wheel 43 can smoothly drive the rope 1 to rotate in the initial state.

[0055] Correspondingly, in order to control the extension and retraction of the piston rod 46112, the device is equipped with a dual-purpose air pump 463 inside the housing 41. The impeller inside the air pump can rotate in both directions and integrates the functions of inflation and suction. Its external interface is connected to the inner cavity of the piston cylinder 46111 through the connecting pipe 464. Compressed gas can be pumped into or extracted from the inner cavity of the piston cylinder 46111 according to the operation requirements, thereby controlling the extension and retraction of the piston rod 46112.

[0056] The working logic of the dual-purpose air pump 463 is as follows: When the horizontal displacement mechanism 3 on one side is started, the dual-purpose air pump 463 injects compressed gas into the piston cylinder 46111 on the corresponding side, causing the pressure inside the piston cylinder 46111 to increase, pushing the piston rod 46112 outward, thereby driving the limit block 4612 to move towards the limit gear 4614, completing the locking of the cooperating wheel 465; when the horizontal displacement mechanism 3 on that side stops working, the dual-purpose air pump 463 extracts gas from the piston cylinder 46111 on the corresponding side, causing a negative pressure to form inside the piston cylinder 46111, pulling the piston rod 46112 towards the limit gear 4614. The retraction causes the limiting block 4612 to disengage from the limiting gear 4614, releasing the locking state of the cooperating wheel 465. When the horizontal displacement mechanisms 3 on both sides work simultaneously, that is, when the top beam is being lifted vertically, the dual-purpose air pump 463 does not work, the piston cylinder 46111 maintains the initial low pressure state, the piston rod 46112 remains retracted, the limiting block 4612 disengages from the limiting gear 4614, and the cooperating wheel 465 can rotate freely, avoiding obstruction to the shape change of the rope 1, ensuring that the two limiting wheels 44 can smoothly open the rope 1 and successfully complete the vertical lifting operation of the top beam.

[0057] Please refer to Figure 4 , Figure 11 Furthermore, this device provides two sets of friction-stopping components 46 on the side of the drive wheel 43 for each of the two guide wheels 45. Specifically, one set of friction-stopping components 46 is provided on the left side of the drive wheel 43 to lock the rope section 1 on the left side of the drive wheel 43; another set of friction-stopping components 46 is provided on the right side of the drive wheel 43 to lock the rope section 1 on the right side of the drive wheel 43. Simultaneously, each of the two guide wheels 45 also has its own independent friction-stopping component 46 for locking the rope section 1 at the guide wheel 45. Moreover, the two friction-stopping components 46 on the same side share a single dual-purpose air pump 463. This configuration significantly reduces the number of air pumps required, simplifies the air path and control system of the equipment, and lowers the purchase cost and operating failure rate of the equipment.

[0058] Therefore, please refer to Figure 6This device has a contact switch 6 installed at the outer end of the rope 1. This switch is fixedly installed on the inner wall of the housing 41, located on the path of the rope 1 between the guide wheel 45 and the drive wheel 43. When the limiting wheel 44 moves away from the housing 41, the rope 1 will be pushed outward by the limiting wheel 44, and its outer wall will trigger the contact switch 6. The triggering principle is as follows: In the initial state, the vertical section of the rope 1 remains vertical, with a certain gap between it and the contact switch 6, and the contact switch 6 is in an untriggered state. When the limiting wheel 44 moves outward, it will push the vertical section of the rope 1 to tilt outward, so that the section of the rope 1 between the limiting wheel 44, the drive wheel 43, and the guide wheel 45 forms a triangular structure. Since the vertical distance between the drive wheel 43 and the guide wheel 45 is fixed, the greater the distance that the limiting wheel 44 moves outward, the greater the tilt angle of the rope 1, and the greater the amount of outward protrusion. When the amount of protrusion reaches a set value, the outer wall of the rope 1 will contact the contact switch 6, triggering its action.

[0059] In actual operation, when the operator needs to control the entire winding mechanism 4 to move horizontally, only the single horizontal displacement mechanism 3 needs to be controlled. In the initial state, the piston rod 46112 on this side is in the retracted state, the cooperating wheel 465 can rotate freely, and the limit wheel 44 can thus move smoothly away from the housing 41, spreading the rope 1. The lifting height of the lower end of the rope 1 is also raised accordingly. When the change in the shape of the rope 1 triggers the contact switch 6 on the corresponding side, the contact switch 6 will control the dual-purpose air pump 463 on the corresponding side to start. Upon activation, the dual-purpose air pump 463 pumps compressed gas into the corresponding piston cylinder 46111, pushing the piston rod 46112 out until the teeth of the limit gear 4614 engage with the limit groove, completing the locking operation of the cooperating wheel 465. At this point, the rope 1 is completely locked with the drive wheel 43 and the guide wheel 45, preventing relative slippage. The lifting process of the lower end of the rope 1 stops. Under the continuous tension of the horizontal displacement mechanism 3, the entire winding mechanism 4 moves horizontally along the horizontal guide rail of the support frame 2, completing the position adjustment. This setting realizes automatic triggering and control of the horizontal movement of the winding mechanism 4, eliminating the need for operators to manually control the start and stop of the air pump, greatly simplifying the operation process, improving the automation level of the equipment, and ensuring the safety of the horizontal movement process. The winding mechanism 4 will only move horizontally after the rope 1 is locked, avoiding the problem of lifting instability caused by the slippage of the rope 1.

[0060] Contact switch 6 is electrically connected to the dual-purpose air pump 463 on the same side, and the control logic is set as follows: when a single contact switch 6 is triggered, the dual-purpose air pump 463 on the corresponding side starts to inflate, and the piston rod 46112 on the corresponding side extends to lock the cooperating wheel 465; when both contact switches 6 are triggered simultaneously, that is, when the vertical lifting operation of the top beam is carried out, the limit wheels 44 on both sides move outward synchronously, triggering the contact switches 6 on both sides simultaneously. At this time, the dual-purpose air pumps 463 on both sides start the suction function, and the piston rods 46112 on both sides remain in the retracted state, releasing the lock on the cooperating wheel 465, ensuring that the cooperating wheel 465 can rotate freely, and the rope 1 can be smoothly opened to complete the vertical lifting of the top beam. This control logic is realized entirely through the triggering state of the contact switch 6, without the need for a complex PLC control system, which greatly simplifies the control logic of the equipment and reduces the complexity of the electrical system of the equipment. It is especially suitable for operation scenarios in coal mines with high explosion-proof requirements and difficult electrical system layout.

[0061] Please refer to Figure 9 , Figure 10 Correspondingly, control components 462 are respectively installed between the two piston cylinders 46111 corresponding to the drive wheel 43 and between the two piston cylinders 46111 corresponding to the guide wheel 45. Each component includes an energy storage tube 4621. The inner cavity of the energy storage tube 4621 is connected to the piston cylinders 46111 on both sides through two synchronization tubes 4622. A normally closed control valve is installed between the two synchronization tubes 4622. When the control valve detects a simultaneous increase in pressure within the inner cavities of the synchronization tubes 4622 on both sides, the control valve opens. The control components 462 are mainly used to regulate the pressure of the piston cylinders 46111 on both sides during the synchronous operation of the dual-sided horizontal displacement mechanism 3 (i.e., vertical lifting of the top beam). This prevents excessive pressure within the cylinders from causing the piston rod 46112 to extend and the cooperating wheel 465 to lock, thereby hindering the rope 1 from opening and lifting the top beam, ensuring smooth vertical lifting operations.

[0062] Specifically, the control valve includes a conical block 4623 that is axially connected to the energy storage tube 4621. The outer diameter of the conical block 4623 gradually increases from top to bottom, forming a conical structure. The lower end opening of the energy storage tube 4621 is provided with a sealing surface that matches the conical surface of the conical block 4623. Under normal conditions, the conical block 4623, under the action of the compression spring 4628, tightly abuts against the conical sealing surface of the energy storage tube 4621, isolating the inner cavity of the energy storage tube 4621 from the inner cavity of the synchronization tube 4622, and the control valve is in a closed state.

[0063] The conical block 4623 is coaxially fitted with a compression spring 4628. The two ends of the spring abut against the inner cavity of the energy storage tube 4621 and the conical block 4623, respectively. With the help of the spring force, the conical block 4623 is always inclined to move downward away from the energy storage tube 4621, ensuring that the conical block 4623 and the conical sealing surface of the energy storage tube 4621 are tightly fitted under normal conditions, and maintaining the closed state of the control valve.

[0064] Meanwhile, two support blocks with trapezoidal vertical projections and hypotenuses abutting against the conical block 4623 are provided on the side of the conical block 4623 near the synchronizing tube 4622. The two support blocks are symmetrically arranged to support the conical block 4623 and restrict its downward movement. Each support block has an unlocking component 4624 on one side. When the pressure inside the corresponding synchronizing tube 4622 increases, the corresponding unlocking component 4624 controls the trapezoidal block 4625 to move away from the conical block 4623.

[0065] The working principle of the control valve is as follows: Under normal conditions, the two support blocks are positioned close to the conical block 4623 by the unlocking component 4624, providing stable support. The conical block 4623 is tightly abutted against the sealing surface of the energy storage tube 4621 under the action of the compression spring 4628. At this time, the control valve is closed, and the air passage between the energy storage tube 4621 and the synchronization tube 4622 is isolated. When the pressure inside the cavity of the synchronization tube 4622 on one side increases (i.e., the horizontal displacement mechanism 3 on one side is activated, performing the horizontal position adjustment operation of the winding mechanism 4), only the unlocking component 4624 on the corresponding side drives the support block on that side to move outward, while the support block on the other side remains in a supported state. The conical block 4623 does not move, the control valve remains closed, and the energy storage tube 4621 is not connected to the air passage. The compressed gas output by the air pump 463 can all enter the corresponding side piston cylinder 46111, pushing the piston rod 46112 to extend and lock the coordinating wheel 465, ensuring the smooth implementation of the horizontal position adjustment operation; when the pressure in the inner cavity of the two side synchronous pipes 4622 rises synchronously (that is, the two side horizontal displacement mechanisms 3 start synchronously to perform the vertical lifting operation of the top beam), the two side unlocking components 4624 synchronously drive the two support blocks to move outward, and synchronously release the support on the conical block 4623; at this time, the conical block 4623 moves down under the elastic force of the compression spring 4628, disengages from the sealing surface of the energy storage pipe 4621, the control valve opens, and the inner cavity of the energy storage pipe 4621 is connected to the inner cavities of the two side synchronous pipes 4622 and the piston cylinder 46111.

[0066] It should be noted that the piston cylinder 46111 and the piston rod 46112 are connected by a sealed sliding connection. The sealing ring between the two has a large coefficient of friction. In other words, for the piston rod 46112 to extend, it must overcome the frictional resistance of the sealing ring. Therefore, the air pressure inside the piston cylinder 46111 must reach a set threshold before the piston rod 46112 can extend. In this device, when the pressure inside the synchronous pipes 4622 on both sides rises synchronously, the control valve opens, and the energy storage pipe 4621 is immediately connected to the air circuit. Since the energy storage pipe 4621 has a large internal volume, the gas pumped by the dual-purpose air pump 463 per unit time will preferentially fill the internal cavity of the energy storage pipe 4621, preventing the pressure inside the piston cylinder 46111 from rising quickly to the piston rod 46112 extension threshold. This ensures that during the operation of the dual-sided horizontal displacement mechanism 3 and the vertical lifting of the top beam, the piston rods 46112 on both sides remain in the retracted state and will not extend the locking coordination wheel 465, completely avoiding any obstruction to the opening of the rope belt 1 and the lifting of the top beam, thus ensuring the smooth progress of the vertical lifting operation.

[0067] Meanwhile, in order to further simplify the control logic of the equipment, the single start time of the dual-purpose air pump 463 is set to a fixed value. There is no need to adjust the running time of the air pump according to the working state. By adjusting the volume of the energy storage tube 4621, the pressure inside the piston cylinder 46111 under different working states can be automatically controlled, which greatly simplifies the control process of the equipment and reduces the difficulty of operation.

[0068] Correspondingly, an axial through hole 4627 is provided at the center of the conical block 4623. A one-way valve 4626 is installed inside the through hole 4627. The one-way valve 4626 is directed from the inner cavity of the energy storage tube 4621 to the inner cavity of the synchronization tube 4622, meaning that gas is only allowed to flow from the energy storage tube 4621 to the synchronization tube 4622, but not from the synchronization tube 4622 to the energy storage tube 4621. The one-way valve 4626 is designed to allow the high-pressure gas in the inner cavity of the energy storage tube 4621 to be smoothly discharged through the one-way valve 4626 when the piston rod 46112 switches from the extended state to the retracted state, so that the pressure in the inner cavity of the energy storage tube 4621 naturally decreases, ensuring that the piston rod 46112 can smoothly retract to its original position.

[0069] Furthermore, the unlocking component 4624 in this device includes a positioning block 46241 located inside the synchronization tube 4622 and fixedly connected to the synchronization tube 4622. The positioning block 46241 adopts a sealing plate structure and forms a sealed and fixed connection with the inner wall of the synchronization tube 4622. A driven block 46243 is provided on the side of the positioning block 46241 near the corresponding piston cylinder 46111 and is slidably and sealed to the synchronization tube 4622. The driven block 46243 can slide linearly along the axial direction of the synchronization tube 4622. The positioning block 46241 and the driven block 46243 cooperate with each other to separate an independent sealed cavity inside the synchronization tube 4622. Pressure changes in the side of the synchronization tube 4622 that is connected to the piston cylinder 46111 will directly act on the driven block 46243, causing the driven block 46243 to produce relative displacement.

[0070] Based on this, the driven block 46243 is fixedly connected to the corresponding trapezoidal block 4625, and a return spring 46242 is provided between the driven block 46243 and the positioning block 46241. The two ends of the return spring 46242 abut against the driven block 46243 and the positioning block 46241 respectively, so that the driven block 46243 always has the tendency to move towards the piston cylinder 46111, ensuring that under normal conditions the driven block 46243 can drive the support block to be in a support position close to the conical block 4623.

[0071] The working principle of the unlocking component 4624 is as follows: Under normal conditions, the pressure inside the synchronizing pipe 4622 is relatively low. The driven block 46243, under the action of the return spring 46242, is in its initial position close to the piston cylinder 46111, causing the support block to be in a supporting position against the conical block 4623, and the control valve remains closed. When the dual-purpose air pump 463 pumps gas into the piston cylinder 46111, and the pressure inside the synchronizing pipe 4622 increases, the high-pressure gas acts on the driven block 46243. The driven block 46243 moves towards the positioning block 46241, overcoming the spring force of the return spring 46242. This, in turn, moves the support block away from the conical block 4623, releasing the support for the conical block 4623. When the pressure inside the synchronizing pipe 4622 decreases, the driven block 46243, under the action of the return spring 46242, moves towards the piston cylinder 46111 to reset, causing the support block to return to its initial support position and re-support the conical block 4623, thus restoring the control valve to its closed state. This unlocking component 4624 achieves automatic control entirely based on the air pressure change within the synchronizing pipe 4622, eliminating the need for additional electrical drive components. This simplifies the equipment structure and ensures the synchronicity and reliability of the control. Whenever the pressure inside the synchronizing pipe 4622 increases, it automatically moves the support block, switching the control valve state, perfectly matching the operating logic of this device.

[0072] Please refer to Figure 1 , Figure 6Specifically, the horizontal displacement mechanism 3 includes a winch 4 fixedly connected to the support frame 2, and a recovery mechanism 5 disposed inside the housing 41. The movable end of the winch 4, i.e., the protruding end of its wire rope, is fixedly connected to the axle of the corresponding side limit wheel 44; the movable end of the recovery mechanism 5, i.e., the protruding end of its traction rope, is fixedly connected to the other side of the axle of the limit wheel 44. Specifically, each limit wheel 44 is configured with a set of horizontal displacement mechanisms 3, i.e., the left limit wheel 44 corresponds to one set of winches 4 and recovery mechanisms 5, and the right limit wheel 44 corresponds to another set of winches 4 and recovery mechanisms 5.

[0073] The working principle of the horizontal displacement mechanism 3 is as follows: When it is necessary to move the limit wheel 44 away from the center of the housing 41, the winch 4 is started to wind up the wire rope, and at the same time, the recovery mechanism 5 releases the traction rope, which can pull the limit wheel 44 to move outward; when it is necessary to move the limit wheel 44 closer to the center of the housing 41 to reset, the recovery mechanism 5 is started to wind up the traction rope, and at the same time, the winch 4 releases the wire rope, which can pull the limit wheel 44 to move inward to reset. Through the cooperation of the winch 4 and the recovery mechanism 5, the moving distance and moving speed of the limit wheel 44 can be precisely controlled, thereby precisely controlling the horizontal moving distance of the recovery mechanism 5 and the vertical lifting height of the top beam, ensuring the accuracy of the operation. At the same time, the winch 4 is fixedly installed on the support frame 2 and does not need to move synchronously with the recovery mechanism 5. The limit wheel 44 can be driven by the wire rope alone, which greatly reduces the difficulty of wiring and installation of the equipment, and avoids the problem of dragging electrical lines of moving parts, improving the safety of the equipment, especially suitable for the working environment in coal mines.

[0074] Please refer to Figure 1 , Figure 2 , Figure 7 Specifically, the rope 1 includes a normal belt 11 wrapped around the outside of the drive wheel 43, and a movable belt 13 detachably connected to the normal belt 11 via hooks 12. The normal belt 11 is a continuous strip structure with an inverted U-shaped upper end fitted onto the drive wheel 43. Two vertical sections extend downwards and wrap around the guide wheel 45 to achieve simultaneous vertical hoisting of the top beam from both sides. The two free ends of the lower side of the normal belt 11 are equipped with hooks 12, which can be hung in the corresponding hoisting holes of the hydraulic support shield beam and the top beam according to the operation requirements, so as to realize the vertical hoisting and horizontal position adjustment of components such as the top beam and the shield beam.

[0075] Correspondingly, the movable belt 13 is an independent belt structure, with hooks 12 at both ends. It can be detachably connected to the hooks 12 on the lower side of the normal belt 11 through the hooks 12. When the movable belt 13 is connected to the normal belt 11, it can form an integral ring structure of rope belt 1. By putting the ring rope belt 1 on the outside of the top beam, the top beam can achieve strong frictional locking between the top beam and the ring rope belt 1 during the rotation of the ring rope belt 1 by using the weight of the top beam itself. At this time, the drive wheel 43 drives the ring rope belt 1 to rotate, which can drive the top beam to complete the flipping operation.

[0076] The advantage of this detachable rope 1 structure is that during actual operation, the operator only needs to pass the movable belt 13 through the underside of the top beam and then connect the hooks 12 at both ends of it to the hooks 12 of the normal belt 11 to complete the laying of the ring rope 1. There is no need to pass the entire rope 1 through the end of the top beam, which greatly reduces the difficulty of laying the rope 1 and improves the work efficiency. It is especially suitable for working conditions where the top beam is large in volume and heavy in weight and the underground working space is small.

[0077] Meanwhile, during the top beam tilting operation, the operator can first control the drive wheel 43 to rotate, so that the two connection points of the normal belt 11 and the movable belt 13 are in a state of one high and one low, that is, one side of the ring rope belt 1 is high and the other side is low. This setting can prevent the hook 12 at the connection point from rigidly colliding and rubbing against the surface of the top beam during the top beam tilting process driven by the ring rope belt 1, preventing damage to the anti-corrosion layer and structural surface of the top beam, and at the same time preventing the hook 12 from touching the valve pipes, hydraulic components and other precision parts installed on the top beam, thus ensuring the safety of the top beam tilting operation.

[0078] Please refer to Figures 1-11 The standardized operating procedure of this device follows the operational logic of top beam assembly / maintenance, and is divided into four core stages: initial standby, precise horizontal alignment, parallel selective operation, and operation reset. The vertical lifting and tilting of the top beam are two independent, parallel, and mutually exclusive operations. On-site, one can be selected for execution based on the actual needs of assembly / maintenance; the two cannot be performed simultaneously. The entire process of coordinated action strictly adheres to the above working principle, as detailed below: Phase 1: Initial Standby State The winding mechanism 4 is completely rested on the initial position of the guide rail of the support frame 2, and there is no relative sliding between the housing 41 and the guide rail; Both horizontal displacement mechanisms 3 on both sides are in a non-working state, both limit wheels 44 are stopped at the initial position close to the central axis of the housing 41, the two vertical sections of the rope 1 remain vertical, and the hoisting end is at the initial minimum height. The dual-purpose air pump 463 is in the stopped state, the piston cylinder 46111 is in the initial low pressure state, the piston rod 46112 is fully retracted, the limit block 4612 is disengaged from the limit gear 4614, the cooperating wheel 465 can rotate freely, and the friction anti-reverse component 46 is in the unlocked state. The control valve of the accumulator tube 4621 is normally closed, the cone block 4623 is in close contact with the sealing surface, and the accumulator tube 4621 is isolated from the air passage of the synchronization tube 4622 and the piston cylinder 46111. Rope 1 is in a normal, stand-alone state, movable belt 13 is not connected, there is a set gap between rope 1 and contact switch 6, and contact switch 6 is in an untriggered state.

[0079] Phase 2: Operation procedure for adjusting the horizontal position of the winding mechanism 4 (alignment of the top beam operation point) Based on the working point of the top beam (lifting hole / flipping sleeve position), the operator determines the displacement direction and starts the corresponding side horizontal displacement mechanism 3: the winch 4 winds up the wire rope, and the corresponding side winding mechanism 4 releases the traction rope simultaneously, pulling the limit wheel 44 on that side to move horizontally away from the center of the shell 41; the other side horizontal displacement mechanism 3 remains in standby state and releases the corresponding limit wheel 44 so that it can move freely. During the outward movement of the working side limit wheel 44, it pushes the vertical section of the corresponding side rope 1 to open outward, causing the rope 1 to protrude outward toward the outer side of the housing 41; when the protrusion reaches the set threshold, the outer wall of the rope 1 triggers the same-side contact switch 6. After the single-sided contact switch 6 is triggered, a trigger signal is sent to the dual-purpose air pump 463 on the same side. The dual-purpose air pump 463 then starts the inflation mode and pumps compressed gas into the piston cylinder 46111 corresponding to the drive wheel 43 and guide wheel 45 on the same side. The pressure in the synchronous pipe 4622 on the same side increases synchronously. At this time, only the pressure of the synchro tube 4622 on one side increases, the control valve of the energy storage tube 4621 remains closed, and all the compressed gas is injected into the inner cavity of the piston cylinder 46111, pushing the piston rod 46112 to overcome the sealing friction resistance and extend, driving the limit block 4612 to move towards the limit gear 4614; if the teeth and the limit groove are not aligned, the limit block 4612 compresses the elastic element through the elastic sliding connection structure to accumulate potential energy. When the cooperating wheel 465 rotates slightly until the teeth are aligned, the elastic element releases potential energy to push the limit block 4612 to complete the engagement and locking, and the cooperating wheel 465 is immediately locked and cannot rotate. After the cooperating wheel 465 is locked, the rope 1 on the same side is fully locked with the drive wheel 43 and the guide wheel 45, and relative slippage cannot occur. The height of the hoisting end of the rope 1 then stops rising. At this time, the horizontal displacement mechanism 3 on the working side continues to operate. The limit wheel 44 is pulled outward, and the lockable rope 1 applies a horizontal pulling force to the housing 41 to overcome the sliding resistance between the housing 41 and the guide rail. The entire winding mechanism 4 is pulled to move horizontally in the opposite direction to the limit wheel 44 along the guide rail. When the winding mechanism 4 moves to the target work point, the operator shuts down the horizontal displacement mechanism 3, locks the winch 4 and the recovery mechanism 5, and fixes the position of the limit wheel 44. The winding mechanism 4 then completes the precise horizontal alignment. The operator can choose to execute one of the two parallel branches below according to the work requirements.

[0080] Parallel Branch 1: Vertical Lifting Operation of Top Beam (Executed independently, not synchronously with the Tilting Operation) This process is applicable to operation scenarios that do not require flipping, such as hoisting and aligning the top beam of the hydraulic support, assembling components, and transporting the entire structure. It is executed independently after the horizontal alignment in Stage 2 is completed. The specific steps are as follows: 1. Lifting connection: The operator attaches the two hooks 12 at the lower end of the normal belt 11 to the corresponding lifting holes of the top beam to complete the rigid connection between the top beam and the lifting rope 1. 2. Dual-side synchronous drive: The horizontal displacement mechanisms 3 on both sides are started synchronously, the winches 4 on both sides are wound up the wire rope synchronously, and the corresponding recovery mechanism 5 releases the traction rope synchronously, driving the two limit wheels 44 on the left and right to move horizontally away from the center of the housing 41 (the left limit wheel 44 moves to the left and the right limit wheel 44 moves to the right). 3. Automatic release control of the cooperating wheel 465: After the double-sided contact switches 6 are triggered simultaneously, control signals are sent to the dual-purpose air pumps 463 on both sides. The dual-purpose air pumps 463 on both sides start the suction function synchronously, continuously drawing air from the corresponding piston cylinder 46111, so that a stable negative pressure is formed in the inner cavity of the piston cylinder 46111, pulling the piston rod 46112 to keep it fully retracted. The limit block 4612 and the limit gear 4614 are continuously disengaged, and the cooperating wheel 465 remains in a free rotation state, without hindering the shape change of the rope 1 throughout the process; 4. Energy storage tube 4621 self-controlled pressure maintenance: The pressure inside the cavity of the dual-sided synchronous tube 4622 increases synchronously, and the unlocking components 4624 on both sides push the support block to move outward synchronously, while releasing the support on the conical block 4623. The conical block 4623 moves downward under the action of the compression spring 4628, and the control valve opens automatically, so that the air passage of the large-capacity energy storage tube 4621 is completely connected with the piston cylinders 46111 on both sides and the synchronous tube 4622; the gas pumped by the dual-purpose air pump 463 preferentially fills the cavity of the energy storage tube 4621, so that the pressure in the piston cylinder 46111 can never reach the threshold of the piston rod 46112 extension, ensuring that the piston rod 46112 remains in the retracted state throughout the entire process, and the cooperating wheel 465 can always rotate freely; 5. Smooth vertical lifting: The limit wheels 44 on both sides move outward synchronously, continuously expanding the vertical section of the rope 1, so that the height of the lifting end of the rope 1 is continuously and smoothly raised, driving the top beam to complete the vertical lifting; after the top beam is raised to the target working height, the operator shuts down the horizontal displacement mechanism 3 on both sides, locks the winch 4 and the recovery mechanism 5 simultaneously, fixes the position of the limit wheels 44, and completes the vertical lifting operation of the top beam, and can then carry out the corresponding assembly and maintenance procedures.

[0081] Parallel Branch Two: Top Beam Tilting Operation Process (Executed independently, not synchronized with the main vertical lifting process) This process is applicable to operational scenarios requiring adjustment of the top beam's posture, such as overturning and overhauling the hydraulic support top beam, installing valve group pipelines, and welding structural surfaces. It is executed independently after the horizontal alignment is completed in Stage 2. A new vertical lifting procedure is added, with the double-sided limit wheels 44 extending outwards after anti-collision posture pre-adjustment, to reserve safety space for the overturning operation. The specific steps are as follows: 1. Layout of the loop rope 1: The operator inserts the movable belt 13 from the underside of the top beam, and quickly and reliably connects the hooks 12 at both ends of the movable belt 13 with the hooks 12 at the lower end of the normal belt 11 to form a complete loop rope 1. Then, the top beam is stably fitted inside the loop rope 1 to complete the layout of the rope 1 for the flipping operation. 2. Anti-collision posture pre-adjustment: The operator starts the drive motor 42 and controls it to rotate slightly in both directions, driving the drive wheel 43 to rotate at low speed, thereby adjusting the shape of the ring rope 1 so that the two connection points of the normal belt 11 and the movable belt 13 are in a misaligned state of one high and one low, so as to avoid the hook 12 colliding with the anti-corrosion layer, structural surface and precision parts such as valve pipes and hydraulic components on the top beam surface during the subsequent flipping process. 3. Vertical lifting at a safe height after tilting: Simultaneously start the horizontal displacement mechanism 3 on both sides, and simultaneously wind up the wire rope on both sides. The corresponding recovery mechanism 5 simultaneously releases the traction rope, driving the two limit wheels 44 on the left and right to extend horizontally outward in a direction away from the center of the housing 41 (the left limit wheel 44 moves to the left and the right limit wheel 44 moves to the right). During the synchronous extension of the two limit wheels 44, the vertical sections of the ropes 1 on both sides are pushed outwards, and the protrusion of the ropes 1 on both sides reaches the set threshold at the same time, triggering the contact switches 6 on the left and right sides simultaneously. The pressure inside the synchronizing pipes 4622 on both sides increases synchronously, and the unlocking components 4624 on both sides push the support block to move outwards synchronously, thereby releasing the support on the conical block 4623. The conical block 4623 moves downwards under the action of the compression spring 4628, and the control valve opens automatically, making the air passages of the large-capacity energy storage pipe 4621, the piston cylinders 46111 on both sides, and the synchronizing pipes 4622 completely connected. The gas pumped by the dual-purpose air pump 463 preferentially fills the inner cavity of the energy storage pipe 4621, so that the pressure inside the piston cylinder 46111 can never reach the extension threshold of the piston rod 46112, ensuring that the piston rod 46112 remains in the retracted state throughout the entire stroke, and the coordinating wheel 465 is always in a free-rotating state. The limit wheels 44 on both sides extend outward synchronously, continuously expanding the vertical section of the rope 1, so that the ring rope 1 drives the top beam to be lifted steadily and vertically until the top beam is lifted to the preset safe flipping height (without the risk of collision with the ground and surrounding equipment). Then, the operator stops the horizontal displacement mechanism 3 on both sides, the winch 4 and the recovery mechanism 5 lock synchronously, the position of the limit wheels 44 is fixed, and the lifting and positioning before flipping is completed. 4. Preparation for high friction transmission: After confirming that the top beam has been lifted to a safe height and its posture is stable, keep the limit components 461 on both sides in an unlocked state. The cooperating wheel 465 can rotate freely. The protrusion 466 of the cooperating wheel 465 passes through the rope 1 and is embedded in the corresponding groove 467 of the drive wheel 43 and the guide wheel 45, pressing the rope 1 tightly against the wheel surface to form a high friction locking transmission structure, eliminating the risk of the rope 1 slipping during the flipping process; 5. Smooth flipping operation: Start the drive motor 42, drive the drive wheel 43 to rotate at a constant speed in the preset flipping direction, and drive the ring rope 1 to rotate stably through strong friction transmission; using the strong static friction between the top beam's own weight and the ring rope 1, the top beam is driven to flip smoothly and synchronously with the rope 1. There is no need to raise the height of the top beam during the process, and only a very small vertical working space is needed to complete the full-angle flipping. 6. Target posture locking: When the top beam is flipped to the target angle required for operation, the operator immediately stops the drive motor 42, locks the drive wheel 43, and at the same time activates the friction anti-reverse component 46 to complete the absolute locking of the rope 1 position, keeping the top beam in a fixed posture after flipping, and then the corresponding flipping assembly and maintenance procedures can be carried out.
