Description

Technical Field

[0001] This utility model relates to the field of lifting and hoisting machine technology, specifically to a lifting and hoisting machine for special equipment. Background Technology

[0002] A crane is a mechanical device used for vertically lifting and horizontally moving heavy objects. It is widely used in construction, ports, logistics, and manufacturing. Cranes achieve the lifting, moving, and positioning of heavy objects through mechanical structures (such as booms, wire ropes, and pulley systems) and power systems (hydraulic, electric, or internal combustion engines). Its main functions include: vertically lifting heavy objects (such as steel and containers); horizontally moving goods to designated locations; and precise positioning and installation (such as bridge components and equipment assembly). The core working principle is as follows: Power system: Drives winches, telescopic booms, and other mechanisms through hydraulic pumps, electric motors, or engines; Mechanical principle: Utilizes the lever principle (boom length) and the labor-saving design of pulley systems to achieve heavy object lifting; Control system: Manual or remote control allows for precise control of lifting, slewing, and luffing movements. Existing technologies struggle to simultaneously meet the dual standards of high-efficiency operation and safety assurance.

[0003] Existing lifting and hoisting machines generally suffer from three technical bottlenecks: their rope deployment and retraction mechanisms mostly adopt fixed guiding structures, which are prone to safety hazards due to rope deviation or excessive swinging during lifting; and the adjustment of limit components is cumbersome and difficult to quickly adapt to different specifications of hoisted objects. The equipment height adjustment mechanism usually relies on an integral support frame, which cannot be flexibly disassembled according to operational needs and suffers from insufficient anti-overturning capacity due to localized stress concentration. The support system design often focuses on a single fixed or movable function, lacking an effective balance between frequent relocation and stable parking, and has poor ground adaptability, easily leading to equipment displacement or structural overload due to unstable support when operating on slopes or soft ground. These defects directly restrict the overall performance of lifting equipment in special operation scenarios. Therefore, a special equipment lifting and hoisting machine is proposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a special equipment lifting and hoisting machine to solve the above-mentioned technical problems that not only lead to a decrease in anti-interference ability, but also make it impossible to guarantee the stability of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting and hoisting machine for special equipment, comprising:

[0006] The outer frame plate and the connecting seat slidably connected to the center of the inner cavity of the outer frame plate, and the upper surface of the connecting seat is equipped with a winding assembly, and the front and back of the outer frame plate are equipped with an adjustment assembly, and the moving end of the adjustment assembly is connected to the connecting seat, and a rope is wound on the winding end surface of the winding assembly, and a lifting hook is provided at the bottom end of the rope.

[0007] A limiting plate is set on the lower part of the surface of the rope, and a threaded sleeve is added between adjacent limiting plates. A connecting screw is threaded to both ends of the threaded sleeve, and the connecting screw is connected to the corresponding limiting plate respectively.

[0008] Support side plates are located on both sides of the lower surface of the outer frame plate, with a limiting groove in the center of each plate. A limiting block is slidably connected to the inner cavity of the limiting groove, and a segmented screw rod is slidably fitted to the outer side of the limiting block. The segmented screw rod consists of three to six sets of threaded screws. Support bases are installed on the lower surface of each support side plate, and the segmented screw rods are threaded to the limiting plates. Threaded rods are threaded around the upper surface of each support base, and movable wheels are added to the front and rear ends of the lower part of the inner cavity of the support base. The bottom end of each threaded rod is rotatably connected to the end of one of the movable wheels. By rotating the threaded rods around the upper surface of the support base, the movable wheels connected to their bottom ends are driven to rise and fall vertically, allowing the lower surface of the support base to contact the ground and form a stable support surface. The overall length of the segmented screw rods can be adjusted by rotating them according to the terrain of the work site. The segmented screw rods adapt to different needs through their threaded connection structure, and their top ends slide vertically along the limiting groove of the support side plate via the limiting block, ensuring that the outer frame plate remains horizontal.

[0009] The adjustment assembly is activated, driving the connecting seat to slide horizontally along the inner cavity of the outer frame plate via its moving end, precisely adjusting the horizontal working position of the winding assembly. During the movement of the connecting seat, the winding assembly moves accordingly, and the rope maintains its connection to the object being lifted via the lifting hook. The winding assembly is activated to wind or release the rope. A limiting plate located on the lower part of the rope surface forms a rigid spacer structure with the connecting screw through a threaded sleeve, preventing excessive twisting or knotting of the rope during winding. Once the object being lifted reaches the target height, the winding assembly is stopped, and rope tension is maintained. The threaded rod is rotated in the opposite direction to bring the moving wheel into contact with the ground, propelling the entire equipment forward by external force. The threaded connection section of the segmented screw is disassembled to shorten the equipment height to meet transportation height restrictions.

[0010] Preferably, the adjustment assembly includes a lead screw and a guide rod, with the lead screw and guide rod respectively disposed on the back and front of the outer frame plate, and a sliding plate and a guide plate respectively sleeved on the surface of the lead screw and the guide rod. The displacement adjustment of the connecting seat is achieved through the coordinated action of the lead screw and the guide rod. When the lead screw rotates, the sliding plate on its surface moves along the threaded trajectory, while the guide plate on the surface of the guide rod synchronously guides the other side of the connecting seat through linear sliding, ensuring that the connecting seat remains horizontal during movement.

[0011] Preferably, the sliding plate and guide plate are connected to the connecting seat, and the end of the lead screw is coaxially connected to a first drive motor, which is connected to the outer frame plate through a motor mount. After the first drive motor is started, its output shaft drives the lead screw to rotate, the sliding plate converts the rotational motion into linear motion, and transmits the displacement to the connecting seat through a mechanical connection; the guide plate slides synchronously along the guide rod, assisting the connecting seat in completing a smooth displacement.

[0012] Preferably, the winding assembly includes a winding roller body, and the rope is wound around the surface of the winding roller body. The winding roller body is rotatably connected to the upper two sides of the connecting seat. The winding roller body performs winding and unwinding operations on the rope through rotational movement. When the winding roller body rotates forward, the rope is wound and tightened; when it rotates in the reverse direction, the rope is gradually released, thereby realizing the adjustment of the height or position of the connected object.

[0013] Preferably, a second drive motor is rotatably connected to the end of the take-up roller, and the second drive motor is connected to the connecting seat through a motor mount. Pulleys are installed at the ends of both take-up rollers, and a transmission belt connects adjacent pulleys. The second drive motor drives one side of the take-up roller to rotate, and the pulley at its end transmits power to the other side of the take-up roller via the transmission belt, achieving synchronous rotation of the two rollers and ensuring consistent winding and unwinding speeds of the ropes on both sides.

[0014] Preferably, the upper surface of the connecting seat has take-up and release holes on both sides, and the take-up and release holes are positioned corresponding to the take-up roller body. Side rotating rods are rotatably connected to the upper and lower parts of the inner wall of the take-up and release holes. When the rope passes through the take-up and release holes, its surface contacts the side rotating rods on the inner wall of the holes. The side rotating rods passively rotate as the rope moves, reducing direct friction between the rope and the edge of the holes.

[0015] Compared with the prior art, this utility model provides a lifting and hoisting machine for special equipment, which has the following beneficial effects:

[0016] The lifting and hoisting machine of this special equipment has a winding assembly that forms a lifting execution mechanism through ropes and lifting hooks. The limiting plate combined with the threaded sleeve on its surface forms an adjustable limiting structure. It can quickly adjust the distance between adjacent limiting plates through the threaded connection between the threaded sleeve and the connecting screw, and can also axially constrain the rope winding and unwinding process, effectively preventing rope entanglement, deviation and excessive swing, and significantly enhancing the safety of lifting operations.

[0017] The support side plate provides vertical guidance for the segmented screw through the sliding cooperation of the limiting groove and the limiting block. The segmented screw adopts a multi-set screw thread splicing structure, which can quickly assemble or disassemble the number of screw segments according to the operation requirements, and form an overall force-bearing frame through the threaded connection with the limiting plate, thereby enhancing the equipment's anti-overturning ability.

[0018] The support base integrates a threaded rod and a movable wheel to form a composite support system. The contact pressure between the support base and the ground can be adjusted by rotating the threaded rod. The movable wheel enables convenient equipment transfer when the threaded rod is raised, and improves parking stability by increasing the support area when the threaded rod is lowered. At the same time, the rotating connection design between the end of the movable wheel and the threaded rod avoids local overload caused by uneven ground during lifting operations, ensuring the adaptability of the equipment under different working conditions.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a technical solution: a lifting and hoisting machine for special equipment, including: (See details) Figure 1 , Figure 5 and Figure 6 The outer frame plate 1 and the connecting seat 2 slidably connected to the center of the inner cavity of the outer frame plate 1 are provided. The upper surface of the connecting seat 2 is equipped with a winding assembly 4, and the front and back of the outer frame plate 1 are provided with an adjustment assembly 3. The moving end of the adjustment assembly 3 is connected to the connecting seat 2, and a rope 14 is wound on the winding end surface of the winding assembly 4. The bottom end of the rope 14 is provided with a lifting hook 19.

[0028] The limiting plate 17 is disposed on the lower part of the surface of the rope 14, and a threaded sleeve 18 is provided between adjacent limiting plates 17, and a connecting screw is threaded to both ends of the threaded sleeve 18, and the connecting screw is connected to the corresponding limiting plate 17 respectively.

[0029] Support side plates 20 are provided on both sides of the lower surface of the outer frame plate 1. A limiting groove 21 is opened in the center of the support side plate 20. A limiting block 22 is slidably connected to the inner cavity of the limiting groove 21. A segmented screw 23 is slidably attached to the outer side of the limiting block 22. The segmented screw 23 is composed of three to six sets of screw threads connected together. A support base 24 is installed on the lower surface of the support side plate 20. The segmented screw 23 is threadedly connected to the limiting plate 17. Threaded rods 25 are threadedly connected to the upper surface of the support base 24 around the perimeter. Moving wheels 26 are added to the front and rear ends of the lower part of the inner cavity of the support base 24. The bottom end of the threaded rod 25 is rotatably connected to the end of the moving wheel 26. By rotating the threaded rods 25 around the upper surface of the support base 24, the moving wheels 26 connected to its bottom end are driven to rise and fall vertically, so that the lower surface of the support base 24 contacts the ground to form a stable support surface; according to the terrain of the work site, the overall length is adjusted by rotating the segmented screw 23. The segmented screw 23 adapts to different needs through the threaded connection structure, and its top end slides vertically along the limiting groove 21 of the support side plate 20 through the limiting block 22 to ensure that the outer frame plate 1 remains horizontal;

[0030] The adjustment assembly 3 is activated, and its moving end drives the connecting seat 2 to slide horizontally along the inner cavity of the outer frame plate 1, precisely adjusting the horizontal working position of the winding assembly 4. During the movement of the connecting seat 2, the winding assembly 4 moves accordingly, and the rope 14 maintains its connection with the object being lifted through the lifting hook 19. The winding assembly 4 is activated to wind or release the rope 14. The limiting plate 17 set on the lower part of the surface of the rope 14 forms a rigid interval structure with the connecting screw through the threaded sleeve 18, preventing excessive twisting or knotting of the rope 14 during winding. When the object being lifted reaches the target height, the winding assembly 4 is stopped and the tension of the rope 14 is maintained. The threaded rod 25 is rotated in the opposite direction to make the moving wheel 26 contact the ground, and the entire equipment is moved by external force. The threaded connection section of the segmented screw 23 is disassembled to shorten the height of the equipment to meet the transportation height limit requirements. The interval device formed by the limiting plate 17 and the threaded sleeve 18 can prevent the rope 14 from winding during the lifting process. The segmented screw 23 adopts a threaded segmented connection method, and a single section can be replaced independently when damaged.

[0031] Please see Figure 2 The adjustment assembly 3 includes a lead screw 5 and a guide rod 6, which are respectively located on the back and front of the outer frame plate 1. A sliding plate 7 and a guide plate 8 are respectively fitted onto the surfaces of the lead screw 5 and the guide rod 6. The displacement adjustment of the connecting seat 2 is achieved through the coordinated action of the lead screw 5 and the guide rod 6. When the lead screw 5 rotates, the sliding plate 7 on its surface moves along the threaded trajectory, while the guide plate 8 on the surface of the guide rod 6 guides the other side of the connecting seat 2 synchronously through linear sliding, ensuring that the connecting seat 2 remains horizontal during movement. The combined design of the lead screw 5 and the guide rod 6 enables precise linear displacement of the connecting seat 2, avoiding the offset problem caused by single-sided driving. Simultaneously, the guide rod 6 shares part of the load, improving structural stability. The sliding plate 7 and the guide plate 8 are connected to the connecting seat 2, and a first drive motor 9 is coaxially connected to the end of the lead screw 5. The first drive motor 9 is connected to the outer frame plate 1 through a motor mount. After the first drive motor 9 starts, its output shaft drives the lead screw 5 to rotate. The sliding plate 7 converts the rotational motion into linear motion and transmits the displacement to the connecting seat 2 through a mechanical connection. The guide plate 8 slides synchronously along the guide rod 6, assisting the connecting seat 2 in completing a smooth displacement. The integrated design of the first drive motor 9 realizes the automated drive of the adjustment component 3, reducing the need for manual operation. At the same time, the coaxial connection between the first drive motor 9 and the lead screw 5 ensures the directness and efficiency of power transmission.

[0032] Please see Figure 3 The winding assembly 4 includes a winding roller 10, with a rope 14 wound around its surface. The winding roller 10 is rotatably connected to both sides above the connecting seat 2. The winding roller 10 rotates to wind up and unwind the rope 14. When the winding roller 10 rotates forward, the rope 14 is wound and tightened; when it rotates in the reverse direction, the rope 14 is gradually released, thereby adjusting the height or position of the connected object. The layout design of the winding roller 10 makes the winding and unwinding path of the rope 14 clear and controllable, avoiding tangling and confusion. A second drive motor 11 is rotatably connected to the end of the winding roller 10, and the second drive motor 11 is connected to the connecting seat 2 through a motor mount. Pulleys 12 are installed at the ends of the winding roller 10, and a drive belt 13 connects adjacent pulleys 12. The second drive motor 11 drives one side of the take-up roller 10 to rotate. The pulley 12 at its end transmits power to the other side of the take-up roller 10 through the transmission belt 13, so as to realize the synchronous rotation of the two rollers and ensure that the take-up and unwinding speeds of the ropes 14 on both sides are consistent. The transmission mechanism of the pulley 12 and the transmission belt 13 ensures the rotational synchronicity of the two take-up rollers 10, avoids the problem of uneven tension of the ropes 14 caused by speed differences, and simplifies the power distribution structure.

[0033] Please see Figure 4The upper surface of the connecting seat 2 has take-up and release holes 15 on both sides, and the take-up and release holes 15 correspond to the positions of the take-up roller body 10. Side rotating rods 16 are rotatably connected to the upper and lower parts of the inner wall of the take-up and release holes 15. When the rope 14 passes through the take-up and release holes 15, its surface contacts the side rotating rods 16 on the inner wall of the hole. The side rotating rods 16 passively rotate with the movement of the rope 14, reducing the direct friction between the rope 14 and the edge of the hole. The rolling friction of the side rotating rods 16 replaces the traditional sliding friction, significantly reducing the wear rate of the rope 14, extending the service life of the rope 14, and reducing the resistance during the take-up and release process.

[0034] This solution involves placing the support base 24 on the work site, rotating the threaded rods 25 around the upper surface of the support base 24, driving the movable wheels 26 connected to its bottom end to rise and fall vertically, so that the lower surface of the support base 24 is in complete contact with the ground to form a stable support surface; according to the usage requirements, the overall length of the segmented screw 23 can be adjusted by adding, removing, or rotating it, and the top of the segmented screw 23 slides vertically along the limiting groove 21 of the support side plate 20 through the limiting block 22;

[0035] Start the first drive motor 9 in the adjustment assembly 3. The first drive motor 9, which is connected to the outer frame plate 1 through the motor base, drives the lead screw 5 to rotate. The sliding plate 7 moves along the threaded trajectory on the surface of the lead screw 5, and simultaneously drives the connecting seat 2 to slide horizontally along the inner cavity of the outer frame plate 1. The other side of the connecting seat 2 slides linearly with the guide plate 8 and the guide rod 6 through the guide plate 8 to ensure that the connecting seat 2 remains horizontal during the movement, and accurately adjusts the horizontal working position of the winding assembly 4.

[0036] The second drive motor 11 in the winding assembly 4 is started. The second drive motor 11, which is connected to the connecting seat 2 via the motor base, drives the winding roller 10 on one side to rotate. The pulley 12 at the end of the pulley drives the winding roller 10 on the other side to rotate synchronously via the transmission belt 13. When the rope 14 passes through the winding hole 15, the side rotating rod 16 on the inner wall of the hole moves and rotates passively with the rope 14, reducing the friction between the rope 14 and the edge of the hole. The limiting plate 17 on the lower part of the surface of the rope 14 forms a rigid spacer structure with the connecting screw through the threaded sleeve 18, preventing the rope 14 from being excessively twisted or knotted during the winding process.

[0037] The connection between the rope 14 and the object being lifted is maintained by the lifting hook 19. The winding assembly 4 is continuously operated to wind or release the rope 14 until the object being lifted reaches the target height. Then the winding assembly 4 is stopped and the rope 14 is kept under tension. During the operation, the adjusting assembly 3 and the winding assembly 4 work together. When the connecting seat 2 moves with the adjusting assembly 3, the winding assembly 4 keeps the rope 14 under tension through the winding roller 10.

[0038] Reverse rotation of the threaded rod 25 causes the end of the moving wheel 26 to contact the ground, and the entire equipment is moved by external force; the threaded connection section of the segmented screw 23 is disassembled to shorten the overall height of the equipment to meet the transportation height restriction requirements; during the disassembly process, each threaded connection section of the segmented screw 23 can be separated independently, and a single damaged section can be replaced individually.
