Description

Technical Field

[0001] This invention relates to the field of lifting machinery technology, and specifically to a self-adjusting, mobile lifting device. Background Technology

[0002] Lifting machinery is a type of mechanical equipment that uses hooks or other lifting devices to lift or move heavy objects horizontally in an intermittent or cyclical manner. It can be used to move objects, saving manpower and transportation costs. Based on type, lifting machinery can be divided into large lifting machinery, medium-sized lifting machinery, and small lifting machinery.

[0003] For small lifting machinery, most have limited mobility, which causes inconvenience in their use. Furthermore, the ropes of small lifting machinery sway during operation, making loading and unloading time-consuming, potentially causing injury, and wasting time and hindering efficiency. Additionally, the inability to achieve stable support during operation results in overall instability due to swaying.

[0004] A common solution to this problem is to install casters at the bottom of the bracket to change the way it moves. While this improves mobility and solves the problem of difficulty in moving, the stability effect is still relatively limited and cannot maintain good working stability. In fact, it may even cause some shaking during operation as the object moves, posing a threat to the user's personal safety and increasing the cost of transportation time. More importantly, it is difficult to unload goods during shaking, thus increasing the time cost.

[0005] In view of the above, in order to overcome the above technical problems, the present invention designs a self-adjusting mobile lifting device, which solves the above technical problems. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to improve the stability of the lifting equipment during the movement process, improve the mobility of the lifting equipment, facilitate movement, realize the transformation between the moving state and the fixed state, provide higher stability in the fixed state, strengthen the stability during the working process, and reduce the suppression of the swaying of the lifting equipment ropes during the movement and working processes.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The present invention provides the following technical solution: a self-adjusting movable lifting device, including a bracket, a support mechanism, a steering mechanism, a connecting mechanism, and a sliding mechanism. The bracket is movably mounted on the ground, and a support mechanism for increasing stability during operation is fixedly installed on one side. The steering mechanism is fixedly installed at both ends of the bottom of the bracket. When moving, rotating the steering mechanism perpendicular to the ground allows for circular turning. When working, retracting the steering mechanism to the bottom of the bracket allows the bracket to fit against the ground for stable operation. The connecting mechanism is slidably mounted in the middle of the bracket. When the working height needs to be changed, the sliding mechanism can be adjusted appropriately to fix it in the bracket to meet the required working height. The sliding mechanism is slidably mounted on the connecting mechanism to cooperate with the clamping mechanism and the magnetic attraction mechanism to fix the swing of the crane rope. The clamping mechanism is fixedly mounted in the center of the sliding mechanism, allowing the crane rope to pass through the clamping mechanism and cooperate with the magnetic attraction mechanism to achieve different degrees of clamping force for stability. The magnetic attraction mechanism is fixedly mounted at both ends of the clamping mechanism, and the clamping force of the clamping mechanism can be controlled by controlling the magnitude of the magnetic attraction force. The adapter mechanism is fixedly mounted on the upper end of the connecting mechanism for quick installation. The anti-slip mechanism is fixedly mounted at the bottom of the bracket to increase stability during operation.

[0009] The bracket includes trapezoidal support openings, support rods, fixing tubes, fixing holes, positioning bosses, fixing bosses, fixing clamps, and rectangular grooves. Multiple trapezoidal support openings are formed from top to bottom in the center of the bracket to enhance its support strength. Support rods are fixedly installed at intervals between each trapezoidal support opening to provide stability to the bracket. The fixing tube is located in the center of the bracket and has multiple fixing holes arranged in a uniform linear array at its lower end to fix the position of the connecting mechanism. The positioning boss is fixedly installed in the center of the first support rod at the lower end. A trapezoidal rubber strip, with a multi-layered structure, is fixedly installed on the positioning boss to cushion the connecting mechanism when it falls, preventing damage to the surface of the support rod. The fixing boss is fixedly installed on the first support rod at the lower end and has a through hole in the center for fixing. The fixing clamp is fixedly installed at the bottom of the bracket. Rectangular grooves for housing the steering mechanism are formed at both ends of the bottom of the bracket. These rectangular grooves allow for quick engagement with the steering mechanism, provide good support, and facilitate the storage of the steering mechanism.

[0010] Furthermore, when heavy objects are being moved during operation, the support rods at both ends of the bracket will be subjected to significant pressure, which may cause mechanical deformation. After multiple support rods are fixedly installed, the pressure applied to the support rods at both ends will be distributed to a large extent, which can also improve the load-bearing capacity of the bracket. When the height needs to be adjusted, the connection structure can be fixed to the required working height through the cooperation of the fixing tube and fixing hole. When not in use, the connection structure can be slid down until the fixing groove and the positioning boss fit together to achieve the function of fixed placement, thus achieving the function of storage without disassembly.

[0011] The support mechanism includes a positioning plate, a fixed frame, a connecting plate, a telescopic rod, a transition shaft, a telescopic pneumatic cylinder, a connecting clamp, a suction pneumatic cylinder, and a suction cup. The positioning plate has a through hole in its center, which is concentrically fixed to the through hole of the fixed boss. The fixed frame has a positioning plate fixedly installed at its bottom end. Multiple connecting plates are provided in the center of the fixed frame to reinforce it. One end of the telescopic rod is fixedly installed at the top of the fixed frame and rotates coaxially with the transition shaft. The other end of the telescopic rod is slidably installed with the telescopic pneumatic cylinder. The telescopic pneumatic cylinder is fixedly installed at the fixed clamp. The connecting clamp has a through hole through which the transition shaft passes and rotates coaxially, while also being fixedly connected to one end of the suction pneumatic cylinder. A suction cup is fixedly installed at the other end of the suction pneumatic cylinder. The telescopic pneumatic cylinder can vertically retract and horizontally expand the fixed frame through movement. When in contact with the ground, the suction pneumatic cylinder can control the suction force of the suction cup to enhance the stability of the support.

[0012] It should be noted that when moved to the working position, the telescopic pneumatic cylinder can be retracted to place the suction cylinder on a horizontal plane, so that the suction cup is attached to the ground. Then, by pumping air from the suction cylinder, the suction cup is tightly attached to the ground to form a certain suction force, thereby stabilizing the support mechanism and achieving lateral stability of the bracket. When not in use, the telescopic pneumatic cylinder can be extended to tilt the support mechanism vertically at a certain angle to one side of the bracket for easy storage and to save space.

[0013] The steering mechanism includes a fixed rectangular plate, an arc-shaped groove, a support frame, a rotating shaft, a rotating frame, and casters. The fixed rectangular plate is fixedly installed in the rectangular groove, and an arc-shaped groove is formed in the center of the fixed rectangular plate. The support frame is fixedly installed at one end of the fixed rectangular plate, and a rotating shaft is rotatably installed in the center of the support frame. The rotating shaft passes through the support frame and is rotatably installed coaxially with the rotating frame. The casters are fixedly installed at the bottom end of the rotating frame. The right-angle end of the rotating frame can fix the casters, thereby enabling the support to move. The arc-shaped end of the rotating frame can rotate the casters and store them in the arc-shaped groove, allowing the support to fit against the ground and achieve a stable working effect. The arc-shaped groove can also accurately position and store the casters in the fixed rectangular plate.

[0014] It is worth noting that when movement is required during operation, the casters can be flipped out of the rectangular groove at the bottom of the bracket to move the entire bracket. Once at the work location, in order to provide a stable processing environment, the casters can be flipped back into the bottom of the bracket and stored in the rectangular groove, so that the anti-slip mechanism is in contact with the ground and provides better stability to the bracket.

[0015] The connecting mechanism includes a movable slide rail, a fixed groove, and positioning holes. The movable slide rail is slidably installed inside the fixed tube, and a fixed groove is provided in the center of the movable slide rail. The positioning holes are arranged in an average linear array at a distance on the lower side of the movable slide rail. After the movable slide rail slides inside the fixed tube to the required height according to the working height, the positioning holes and the fixed holes are coaxially fixed to achieve the required processing height. The movable slide rail can make the sliding mechanism slide, thereby suppressing the swing of the crane rope.

[0016] In addition, when there are requirements for working height during use, the connecting structure can be adjusted and the working height position can be determined by fixing it with the support fixing pipe before processing can be carried out. It is also easy to disassemble. When disassembly is required, the connecting mechanism can be pulled out of the fixing pipe to complete the disassembly.

[0017] The sliding mechanism includes a rectangular fixed plate, a fixed shaft, a rotating wheel, a limiting disc, and a fixed disc. The rectangular fixed plate is movably mounted on the connecting mechanism and has through holes at its upper and lower ends. One end of the fixed shaft passes through the through hole and is rotatably mounted on the rotating wheel. A limiting disc with a larger diameter is provided on one side of the rotating wheel. The center of the fixed disc is rotatably connected to the other end of the fixed shaft. The limiting disc fits against the moving slide rail of the connecting mechanism to prevent the rotating wheel from moving laterally and affecting the vertical sliding of the sliding mechanism. The fixed disc, through its cooperation with the fixed shaft, ensures that the rotating wheel fits tightly against the inner side of the moving slide rail of the connecting mechanism, thereby suppressing the shaking of the rotating wheel and preventing the sliding mechanism from becoming unstable.

[0018] It should be noted that when the sliding mechanism is slidably installed in the connecting mechanism, it will cause a certain degree of circumferential offset of the rotating wheel. Therefore, the rotating wheel is fixedly installed on one side of the rectangular fixed plate. By fitting the rectangular fixed plate with the connecting structure and clamping the rotating wheel, the offset of the sliding mechanism during operation can be reduced to a certain extent. Then, the stability of the rotating wheel is further strengthened by fixing the disc, which enhances the suppression of circumferential offset. Finally, the rotating wheel is completely limited on the moving slide rail by fitting the limiting disc with the moving slide rail of the connecting mechanism, so that the rotating wheel is completely fitted with the moving slide rail, thereby completely eliminating the circumferential offset.

[0019] The clamping mechanism includes a square housing, an O-shaped groove, a fixed circular hole, a rubber tube, a sliding shaft, a roller, a limiting roller, and a rotation sensor. The square housing has O-shaped grooves at its front and rear ends, allowing the inner surface of the groove to tightly fit the sliding shaft for stable sliding. Fixed circular holes are located at both ends, with one end of the rubber tube fixedly installed in each hole. The other end of the rubber tube is fixedly installed inside the sliding mechanism. The sliding shaft is slidably mounted within the O-shaped groove, and a roller is rotatably mounted in the middle of the sliding shaft. Limiting rollers are located at both ends of the roller. The roller keeps the crane rope in contact with its surface, suppressing lateral swaying. The limiting rollers control the forward and backward movement of the rope within a limited range, reducing forward and backward swaying. The rotation sensor is fixedly installed above the inner surface of the square housing. When the rotation of the roller is detected, a feedback signal is sent to the magnetic attraction mechanism to control the magnitude of the magnetic force.

[0020] It is worth noting that when the lifting equipment is working or moving, the crane's rope will sway due to the force applied when loading and unloading objects and the force applied by the acceleration brought about by the movement. The rollers of the clamping mechanism and the limiting rolling mechanism fix the rope within a limited space, thereby slightly suppressing the swaying of the rope and increasing the stability of the rope during operation.

[0021] The magnetic attraction mechanism includes an L-shaped cable outlet tube, a cylindrical shell, a circular groove, an annular groove, a cable outlet hole, a sliding block, an electromagnet, and a spring. One end of the L-shaped cable outlet tube is fixedly mounted on the rubber tube of the clamping mechanism. The L-shaped cable outlet tube has a right-angle bend in the middle, which allows the wire a certain bend width to pass smoothly through. The right-angle bend also provides stable support strength, making it less likely to break and damage the wire. The other end of the L-shaped cable outlet tube is fixedly mounted on a cylindrical shell. The cylindrical shell has a circular groove inside and an annular groove on its side. The annular groove can... The sliding shaft is tightly fitted to the surface to prevent up-and-down wobbling and form a stable sliding state. Cable outlet holes are also provided at both ends. The sliding block is slidably mounted on the circular groove, and an electromagnet is fixedly mounted on one side. Its side end is fixedly mounted on the sliding shaft of the clamping mechanism. The spring is rotatably mounted on the outside of the electromagnet and fixedly mounted on one side of the sliding block. The sliding block and the spring can make the clamping mechanism loosen and limit the crane. When the electromagnet is working, it can make the sliding block compress the spring to tightly fit the crane rope for a more stable limit.

[0022] Importantly, when the rope is confined within the clamping mechanism, the vertical extension and retraction of the rope during crane operation causes the clamping mechanism's rollers to rotate. This triggers a signal from the rotation sensor, which in turn sends a feedback signal to the magnetic attraction mechanism. This strengthens the magnetic force of the magnetic attraction mechanism, compressing the spring and clamping the rope with the rollers, thus increasing the suppression of rope sway. When the crane stops operating, the rotation sensor loses its feedback signal, restoring the clamping mechanism's ability to suppress minor sway. During movement, when the accelerometer in the anti-slip mechanism detects movement of the caster wheel, it sends a feedback signal to the magnetic attraction mechanism, strengthening the electromagnet's magnetic force and compressing the spring, thus enhancing the rope's stability. When movement stops, the feedback signal disappears, restoring the clamping mechanism's ability to suppress minor rope sway.

[0023] The adapter mechanism includes a right-angle adapter frame, a load-bearing plate, a rectangular opening, and a load-bearing slide rail. The right-angle adapter frame is fixedly installed at the top of the connecting mechanism. The load-bearing plate is fixedly installed at the corner of the right-angle adapter frame. The rectangular opening is vertically opened at the lower end of the right-angle adapter frame, and a rectangular opening is also horizontally opened at the upper end of the right-angle adapter frame. The rectangular opening allows the load-bearing slide rail to pass through and play a fixing role, and can well accept the load force brought by the load-bearing slide rail. A thin rubber layer is provided on the inner surface of the rectangular opening. The thin rubber layer has small circular protrusions arranged in an alternating linear array. When the rectangular opening is subjected to multi-directional moving forces during operation, the alternating linear array arrangement can suppress the moving forces in multiple directions, thereby effectively suppressing the sliding deviation of the load-bearing slide rail in the rectangular opening. The small protrusions on the thin rubber layer can effectively alleviate the shaking sensation brought to the connecting mechanism during operation, thereby effectively suppressing the shaking of the bracket. The load-bearing slide rail is slidably installed in the horizontal rectangular opening.

[0024] In addition, when the crane is operating, it will cause the load-bearing slide rail to sway from side to side. Using a thinner rubber layer can prevent the load-bearing slide rail from sliding left and right within the horizontal rectangular opening when the crane is operating on it. The small circular protrusions on the top of the thinner rubber layer can protect the surface of the load-bearing slide rail from scratches, reduce wear on the load-bearing slide rail during long-term operation, and also alleviate the swaying of the load-bearing slide rail when the crane is operating.

[0025] The anti-slip mechanism includes a short trapezoidal load-bearing block, a long trapezoidal load-bearing block, and an acceleration sensor. The short trapezoidal load-bearing block is fixedly installed at both ends of the bottom of the bracket, and the long trapezoidal load-bearing block is fixedly installed at the center of the bottom of the bracket. The wider tops of the short and long trapezoidal load-bearing blocks allow the load weight to be distributed evenly on the load-bearing blocks and concentrated on the ground through the shorter bottoms. Anti-slip strips are fixedly installed on the bottom surfaces of both the short and long trapezoidal load-bearing blocks. The anti-slip strips have tiny, densely packed teeth on their surfaces, and these tiny, densely packed teeth are evenly distributed in a linear array. An acceleration sensor is fixedly installed on the long trapezoidal load-bearing block to provide feedback signals to the magnetic attraction mechanism when the movement of the omnidirectional wheel is detected.

[0026] It is worth noting that when the casters move, the acceleration sensor can detect the state of the casters and send a signal to the magnetic attraction mechanism to control the magnitude of the magnetic force. When the casters are moved to the working position, they can be flipped over and stored in the rectangular groove, so that the short trapezoidal load-bearing blocks and the long trapezoidal load-bearing blocks serve as the support points of the support frame and are in contact with the ground. The tiny, densely packed toothed racks on the surface can effectively eliminate the shaking of the support frame during the operation of the crane, thereby further ensuring the quality of work.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. This invention, by incorporating a sliding mechanism, a clamping mechanism, and a magnetic attraction mechanism, enables the sliding mechanism to adjust the working positions of the clamping and magnetic attraction mechanisms by sliding up and down the connecting mechanism. This ensures that the clamping mechanism remains tightly attached to the hook at the end of the crane rope, thereby achieving accompanying movement of the crane rope. This helps suppress rope swaying during movement, changing the traditional method where the rope sways with the movement of objects, posing a threat to personal safety, increasing transportation time, and making it difficult to unload goods. The clamping mechanism uses sensors to detect changes in roller rotation, enabling rapid control of the magnetic force of the magnetic attraction mechanism, thus suppressing rope swaying and ensuring rope stability. The anti-slip mechanism uses sensors to detect the acceleration of the caster wheels, enabling rapid control of the magnetic force of the magnetic attraction mechanism, thereby suppressing rope swaying during crane movement.

[0029] 2. This invention, by setting up a support mechanism, a steering mechanism, and an anti-slip mechanism, allows the casters to be switched from moving to stationary mode when not in use by flipping and retracting the steering mechanism. This eliminates the unstable support caused by using the casters as a support point and ensures that the bracket can be directly in contact with the ground without shaking. Furthermore, the anti-slip mechanism provides a more stable working environment for the bracket and prevents it from sliding against the ground. The support mechanism also helps to fix the bracket's lateral sway, thus making the working environment more stable. Attached Figure Description

Detailed Implementation

[0046] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0047] Example 1:

[0048] like Figures 1 to 14As shown, a self-adjusting movable lifting device includes a bracket 1, a support mechanism 2, a steering mechanism 3, a connecting mechanism 4, and a sliding mechanism 5. The bracket 1 is movably installed on the ground, and the support mechanism 2 is fixedly installed on one side to increase stability during operation. The bracket 1 can be made of aluminum alloy, which is lightweight, does not place too much burden on the user, and has good strength to withstand a certain weight load. The steering mechanism 3 is fixedly installed at both ends of the bottom of the bracket 1. When moving, rotating the steering mechanism 3 perpendicular to the ground can achieve circumferential turning. When working, retracting the steering mechanism 3 to the bottom of the bracket 1 can make the bracket 1 fit against the ground to achieve a stable working effect. The connecting mechanism 4 is slidably installed in the middle of the bracket 1. When the working height needs to be changed, it can be adjusted according to the height. The sliding mechanism 5 is adjusted appropriately to fix it in the bracket 1 to achieve the required working height. The sliding mechanism 5 is slidably installed on the connecting mechanism 4 to cooperate with the clamping mechanism 6 and the magnetic attraction mechanism 7 to fix the swing of the crane rope. The clamping mechanism 6 is fixedly installed in the center of the sliding mechanism 5, allowing the crane rope to pass through the clamping mechanism 6 and cooperate with the magnetic attraction mechanism 7 to achieve different degrees of clamping force for stability. The magnetic attraction mechanism 7 is fixedly installed at both ends of the clamping mechanism 6, and the clamping force on the clamping mechanism 6 is controlled by controlling the magnitude of the magnetic attraction force. The adapter mechanism 8 is fixedly installed on the upper end of the connecting mechanism 4 for quick installation with the connecting mechanism 4. The anti-slip mechanism 9 is fixedly installed at the bottom of the bracket 1 to increase the sway during operation and increase stability.

[0049] like Figure 2 , Figure 3 and Figure 13As shown, the bracket 1 includes trapezoidal support openings 11, support rods 12, fixing tubes 13, fixing holes 14, positioning bosses 15, trapezoidal rubber strips 16, fixing bosses 17, fixing clamps 18, and rectangular grooves 19. Multiple trapezoidal support openings 11 are provided from top to bottom in the center of the bracket 1 to enhance its support strength. Support rods 12 are fixedly installed at intervals between each trapezoidal support opening 11 to provide stability to the bracket 1. The height of the support rods 12 can be selected as 100mm to ensure good support performance. The fixing tube 13 is located in the center of the bracket 1. The outer perimeter of the fixing tube 13 is 220mm*220mm, the inner thickness is 20mm, and the inner diameter is 200mm*200mm. A rectangular groove is provided at the lower end. An average linear array of multiple fixing holes 14 is used to fix the position of the connecting mechanism 4. The positioning boss 15 is fixedly installed in the center of the first support rod 12 at the lower end. A trapezoidal rubber strip 16 is fixedly installed on the positioning boss 15. The trapezoidal rubber strip 16 has a multi-layer structure and is used to buffer the connecting mechanism 4 when it falls to prevent the connecting mechanism 4 from damaging the surface of the support rod 12. The fixing boss 17 is fixedly installed on the first support rod 12 at the lower end and has a through hole for fixing in the center. The fixing clamp 18 is fixedly installed at the bottom of the bracket 1. Rectangular grooves 19 for accommodating the steering mechanism 3 are opened at both ends of the bottom of the bracket 1. The parameters of the rectangular grooves 19 are 300mm*200mm*80mm.

[0050] like Figure 2 As shown, the support mechanism 2 includes a positioning plate 21, a fixing frame 22, a connecting plate 23, a telescopic rod 24, a transition shaft 25, a telescopic pneumatic cylinder 26, a connecting clamp 27, a suction pneumatic cylinder 28, and a suction cup 29. The positioning plate 21 has a through hole in its center, which is concentrically fixed to the through hole of the fixing boss 17. The length of the positioning plate 21 can be 600mm, and its thickness can be 30mm. The positioning plate 21 is fixedly installed at the bottom of the fixing frame 22. Multiple connecting plates 23 are provided in the center of the fixing frame 22 to reinforce it. The connecting plates 23 are 40mm thick to achieve good reinforcement. One end of the telescopic rod 24 is fixedly mounted on the connecting plate 23. The telescopic rod 24 is mounted on the top of the fixed frame 22 and is rotatably mounted coaxially with the adapter shaft 25. The other end of the telescopic rod 24 is slidably mounted with the telescopic pneumatic cylinder 26. The telescopic pneumatic cylinder 26 is fixedly mounted on the fixed clamping plate 18. The connecting clamping plate 27 has a through hole so that the adapter shaft 25 can pass through the through hole and rotate coaxially. At the same time, it is also fixedly connected to one end of the adsorption pneumatic cylinder 28. The other end of the adsorption pneumatic cylinder 28 is fixedly mounted with a suction cup 29. The telescopic pneumatic cylinder 26 can make the fixed frame 22 vertically retract and horizontally expand by movement. When it is in contact with the ground, the adsorption pneumatic cylinder 28 can control the suction force of the suction cup 29 to strengthen the stability of the bracket 1.

[0051] like Figure 3 and Figure 4 As shown, the steering mechanism 3 includes a fixed rectangular plate 31, an arc-shaped groove 32, a support frame 33, a rotating shaft 34, a rotating frame 35, and a caster wheel 36. The fixed rectangular plate 31 is fixedly installed in the rectangular groove 19. The parameters of the fixed rectangular plate 31 are the same as those of the rectangular groove 19, 300mm*200mm*80mm, so that the steering mechanism 3 fits snugly against the rectangular groove 19. An arc-shaped groove 32 is formed in the center of the fixed rectangular plate 31. The parameters of the arc-shaped groove 32 are the same as those of the caster wheel 36, with a diameter of 180mm and a width of 23mm. The support frame 33 is fixedly installed in the rectangular groove 19. A rotating shaft 34 is fixedly installed at one end of the fixed rectangular plate 31 and rotatably installed in the center of the support frame 33. The rotating shaft 34 passes through the support frame 33 and is rotatably installed coaxially with the rotating frame 35. The universal wheel 36 is fixedly installed at the bottom of the rotating frame 35. The right-angle end of the rotating frame 35 can fix the universal wheel 36, thereby enabling the support 1 to move. The arc end of the rotating frame 35 can rotate the universal wheel 36 into the arc groove 32, so that the support 1 can fit against the ground to achieve a stable working effect. The arc groove 32 can also accurately position the universal wheel 36 and store it in the fixed rectangular plate 31.

[0052] like Figure 5 As shown, the connecting mechanism 4 includes a movable slide rail 41, a fixed groove 42, and a positioning hole 43. The movable slide rail 41 is slidably installed inside the fixed tube 13, and a fixed groove 42 is provided in the center of the movable slide rail 41. The outer end parameters of the slide rail are 200mm*200mm, and the inner parameters are 160mm*50mm, so that it fits closely with the rotating wheel 53. The positioning holes 43 are arranged in an average linear array on the lower side of the movable slide rail 41 at a certain distance. After the movable slide rail 41 slides in the fixed tube 13 to reach the required height according to the working height, the positioning holes 43 and the fixed holes 14 are coaxially fixed to achieve the required processing height. The movable slide rail 41 can make the sliding mechanism 5 slide, thereby suppressing the swing of the crane rope.

[0053] like Figure 7 and Figure 8As shown, the sliding mechanism 5 includes a rectangular fixed plate 51, a fixed shaft 52, a rotating wheel 53, a limiting disc 54, and a fixed disc 55. The rectangular fixed plate 51 is movably mounted on the connecting mechanism 4 and has through holes at its upper and lower ends. One end of the fixed shaft 52 passes through the through hole and is rotatably mounted with the rotating wheel 53. The rotating wheel 53 has a diameter of 50 mm and a width of 20 mm. A limiting disc 54 with a larger diameter is provided on one side of the rotating wheel 53. The limiting disc 54 has a diameter of 90 mm. The center of the fixed disc 55 is rotatably connected to the other end of the fixed shaft 52. The limiting disc 54 fits against the moving slide rail 41 of the connecting mechanism 4 to prevent the rotating wheel 53 from moving laterally and affecting the vertical sliding of the sliding mechanism 5. The fixed disc 55, through its cooperation with the fixed shaft 52, ensures that the rotating wheel 53 fits tightly against the inner side of the moving slide rail 41 of the connecting mechanism 4, thereby suppressing the shaking of the rotating wheel 53 and preventing the sliding mechanism 5 from becoming unstable.

[0054] It should be noted that when the crane rope extends downwards, the weight of the sliding mechanism 5 will cause the clamping mechanism 6 to exert a downward pulling force F1 on the hook at the end of the rope, which will strengthen and stabilize the rope. When the sliding mechanism 5 touches the bracket 1 along the connecting mechanism 4, the sliding mechanism 5 stops moving, and the pulling force F1 will gradually decrease until the rope extends beyond the stopping position of the sliding mechanism 5, at which point the pulling force F1 disappears. At this time, the clamping mechanism 6 will descend a certain distance due to its own weight as the rope extends. During this distance, the clamping mechanism 6 will exert a gravitational force G on the hook at the end of the rope. When the crane rope retracts upwards, when the retraction exceeds the stopping position of the sliding mechanism 5, the sliding mechanism 5 will slowly restore a pulling force F2 on the hook at the end of the rope due to its own weight, thereby restoring the rope to a strengthened and stable state. At this time, F2 = F1, and F1 = F2 > G.

[0055] like Figure 6As shown, the clamping mechanism 6 includes a square housing 61, an O-shaped groove 62, a fixing hole 63, a rubber tube 64, a sliding shaft 65, a roller 66, a limiting roller 67, and a rotation sensor 68. The square housing 61 has O-shaped grooves 62 at its front and rear ends. The external parameters of the square housing 61 can be 100mm*100mm, and the internal parameters are 90mm*90mm, with a 10mm wall thickness to ensure the material properties of the square housing 61 are preserved and prevent deformation or bending. The O-shaped groove 62 has a width of 10mm and fixing holes 63 at both ends. One end of the rubber tube 64 is fixedly installed in each fixing hole 63, and the other end of the rubber tube 64 is fixedly installed inside the sliding mechanism 5. The sliding shaft 65 is slidably installed in the O-shaped groove. Inside 62, the sliding shaft 65 and the O-shaped groove 62 are tightly fitted with a diameter of 10mm to ensure smooth sliding. A roller 66 with a parameter of 30mm is rotatably installed in the middle of the sliding shaft 65. The roller 66 has 40mm limiting rollers 67 at both ends to ensure that the rope is limited inside the limiting rollers 67 and will not slide out of the rolling range as the roller 66 rolls. The roller 66 keeps the crane rope in contact with the surface of the roller 66 to suppress the left and right swaying of the rope. The limiting rollers 67 can control the forward and backward movement of the rope within the limited range to reduce the forward and backward swaying of the rope. The rotation sensor 68 is fixedly installed above the inner surface of the square housing 61. When the rotation of the roller 66 is detected, a feedback signal is given to the magnetic attraction mechanism 7 to control the magnitude of the magnetic force.

[0056] like Figure 9 , Figure 10 and Figure 11As shown, the magnetic attraction mechanism 7 includes an L-shaped cable outlet tube 71, a cylindrical shell 72, a circular groove 73, an annular slide groove 74, a cable outlet hole 75, a sliding block 76, an electromagnet 77, and a spring 78. One end of the L-shaped cable outlet tube 71 is fixedly installed on the rubber tube 64 of the clamping mechanism 6. The L-shaped cable outlet tube 71 has a right-angle bend in the middle, which can leave a certain bend width for the wire to pass through smoothly. The right-angle bend can also provide stable support strength, making it less likely to break and damage the wire. A cylindrical housing 72 is fixedly installed at the other end of the tube 71. The cylindrical housing 72 has a diameter of 30mm and a length of 50mm. A circular groove 73 with a diameter of 20mm and a length of 40mm is formed inside the cylindrical housing 72, and an annular groove 74 is formed on the side. The sliding shaft 65 fits into the annular groove 74 and has a diameter of 10mm. Outlet holes 75 are also formed at both ends. The sliding block 76 is slidably mounted on the circular groove 73. To ensure that the sliding block 76... The sliding block 76 slides smoothly within the circular groove 73. The sliding block 76 has a diameter of 20mm and a length of 15mm, and an electromagnet 77 is fixedly installed on one side. The electromagnet 77 is circular with a diameter of 18mm, and its side end is fixedly installed on the sliding shaft 65 of the clamping mechanism 6. The spring 78 is rotatably installed on the outside of the electromagnet 77. The parameters of the spring 78 can be selected as an outer end diameter of 20mm, a spring diameter of 1mm, and an effective number of coils of 6. To ensure that the clamping mechanism 6 can slightly clamp the crane rope even when the magnetic attraction mechanism 7 is not energized, the spring 78 has a length of 10mm, which is less than the rope width to clamp the rope. It is fixedly installed on one side of the sliding block 76. The sliding block 76 and the spring 78 can provide a relaxed limit for the clamping mechanism 6 on the crane. When the electromagnet 77 is working, the sliding block 76 can compress the spring 78 to achieve a tighter fit and more stable limit on the crane rope.

[0057] like Figure 12As shown, the adapter mechanism 8 includes a right-angle adapter frame 81, a load-bearing plate 82, a rectangular opening 83, and a load-bearing slide rail 84. The right-angle adapter frame 81 is fixedly installed at the top of the connecting mechanism 4, and the load-bearing plate 82 is fixedly installed at the corner of the right-angle adapter frame 81. During operation, the horizontal rectangular opening 83 will be subjected to gravity M1. At this time, the load-bearing plate 82 will distribute nearly half of the gravity M1 and distribute the remaining gravity M2 to the right-angle adapter frame 81. At this time, M1 / 2 + M2 = M1. The rectangular opening 83 is vertically opened at the lower end of the right-angle adapter frame 81, and a rectangular opening 83 is also horizontally opened at the upper end of the right-angle adapter frame 81. The rectangular opening 83 allows the load-bearing slide rail 84 to pass through. The rectangular opening 83 serves a fixing function and can effectively accept the load force brought by the load-bearing slide rail 84. A thin rubber layer is provided on the inner surface of the rectangular opening 83. The thin rubber layer has small circular protrusions arranged in an alternating linear array. When the rectangular opening 83 is subjected to multi-directional moving forces during operation, the alternating linear array arrangement can suppress the moving forces in multiple directions, thereby effectively suppressing the sliding deviation of the load-bearing slide rail 84 within the rectangular opening 83. The small protrusions on the thin rubber layer can effectively alleviate the shaking sensation brought to the connecting mechanism 4 during operation, thereby effectively suppressing the shaking of the bracket 1. The load-bearing slide rail 84 is slidably installed within the transverse rectangular opening 83.

[0058] like Figure 3 and Figure 14 As shown, the anti-slip mechanism 9 includes a short trapezoidal load-bearing block 91, a long trapezoidal load-bearing block 92, anti-slip strips 93, and an acceleration sensor 94. The short trapezoidal load-bearing block 91 is fixedly installed at both ends of the bottom of the bracket 1, and the long trapezoidal load-bearing block 92 is fixedly installed at the center of the bottom of the bracket 1. The wider tops of the short trapezoidal load-bearing block 91 and the long trapezoidal load-bearing block 92 can distribute the load weight onto the load-bearing block and concentrate the load weight onto the ground through the shorter bottoms. Anti-slip strips 93 are fixedly installed on the bottom surfaces of both the short trapezoidal load-bearing block 91 and the long trapezoidal load-bearing block 92. The surface of the anti-slip strips 93 is provided with tiny dense teeth, which are evenly distributed in a linear array. An acceleration sensor 94 is fixedly installed on the long trapezoidal load-bearing block 92 to provide feedback signals to the magnetic attraction mechanism 7 when the movement of the omnidirectional wheel 36 is detected.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
