Description

Technical Field

[0001] This invention belongs to the field of water conservancy equipment technology, and relates to a suspended gate hoist, particularly a mobile suspended gate hoist. Background Technology

[0002] Gate hoists are used in various large-scale water supply and drainage, water conservancy and hydropower projects to control the lifting and lowering of various large and medium-sized cast iron gates and steel gates to achieve the purpose of opening and closing. Mobile suspended gate hoists are a type of opening and closing equipment specifically used to operate fast gates. Fast gates are used to protect generator units or steel pipes. Normally, they are suspended above the orifice. When a generator, water pump or steel pipe has an accident, it can quickly cut off the water flow to prevent the accident from escalating. The closing time of the fast gate should meet the protection requirements of the generator unit and steel pipe. Generally, the gate hoist is required to close the fast gate within 2 minutes.

[0003] A search revealed a Chinese patent document disclosing an easy-to-maintain suspended mobile gate hoist [Application No.: CN202023216375.1; Publication No.: CN214783713U]. This suspended mobile gate hoist includes a gate hoist, a moving rod, and a maintenance plate. The top surface of the moving rod is provided with a moving rail, and a moving head is movably connected inside the moving rail. A suspension rod is fixedly connected to the bottom surface of the moving head, and the bottom end of the suspension rod is fixedly connected to the maintenance plate.

[0004] Although the suspended mobile gate hoist disclosed in this patent facilitates cleaning and maintenance by brushing the outer wall of the hoist with a cleaning ring and a cleaning sponge, cleaning the outer wall of the hoist with a cleaning brush cannot effectively lubricate the internal steel cable, affecting the service life and working quality of the steel cable. Moreover, due to the fixed position of the winding drum, the steel cable is prone to accumulation and tangling during winding, resulting in poor opening and closing efficiency and seriously affecting the opening and closing speed of the gate. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a mobile suspended gate hoist. The technical problem this invention aims to solve is: how to effectively guide and store the steel cable to ensure the gate's opening and closing efficiency and operational balance, while simultaneously providing convenient lubrication and maintenance for the steel cable to guarantee its working quality.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A mobile suspended gate hoist includes a frame, a rotating shaft rotatably connected inside the frame, a drive motor for driving the rotating shaft, and two cable drums fixedly connected to the outer wall of the rotating shaft. Steel cables are symmetrically wound around the outer walls of both sides of the cable drums. An upper guide wheel is connected to the outer wall of the steel cable. The upper guide wheel is located below the frame, and a lower guide wheel is attached to the top wall of the upper guide wheel. A balance wheel is provided above the lower guide wheel. The balance wheel is rotatably connected to the lower part of the frame, and the steel cables on both sides are sleeved on the outer wall of the balance wheel in an inverted "U" shape.

[0008] A fixed frame is fixedly connected to the surface of the frame, and a movable rod is rotatably connected above the fixed frame. The movable rod is connected to the rotating shaft through a transmission unit. A gear column is fixedly connected to the outer wall of the movable rod, and two racks are symmetrically meshed on the upper and lower outer walls of the gear column. The racks are slidably connected to the surface of the fixed frame. A guide plate is fixedly connected to the outer wall of the racks, and a steel cable is movably connected through the inside of the guide plate.

[0009] The upper and lower ends of the fixed frame are both fixedly connected to toothed plates, and the toothed plates are arranged parallel to the toothed rack. The outer wall of the toothed plate is connected to an oil injection component, and the oil injection component is fixedly connected to the surface of the guide plate.

[0010] The oil injection assembly includes a fixed cylinder, which is fixedly installed on the surface of the guide plate. A main gear is rotatably connected inside the fixed cylinder, and a driven gear is meshed with the outer wall of the main gear. A rotating frame is fixedly connected to the inner wall of the driven gear, and the rotating frame is rotatably connected inside the fixed cylinder.

[0011] Multiple oil-filling beads are telescopically arranged above the rotating frame. A telescopic spring is fixedly connected to one side of each oil-filling bead. The telescopic spring is fixedly connected to the inner wall of the fixed cylinder. Multiple oil-absorbing sponges are telescopically arranged inside the fixed cylinder. The oil-absorbing sponges are fixedly connected to one side of each oil-filling bead, and a sealing plate is fixedly connected to the end of the oil-absorbing sponge away from the oil-filling bead.

[0012] An oil chamber is connected above the fixed cylinder. The oil chamber has an annular structure and a piston is telescopically connected inside the oil chamber. A vertical rod is fixedly connected to the top of the piston, and a top ring is fixedly connected to the top of the vertical rod.

[0013] The working principle of this invention is as follows: During operation, the drive motor is energized, causing the rotating shaft to rotate. This causes the cable drum to wind and unwind the steel cable on the outer wall. With an upper guide wheel and a balance wheel installed below the frame, and a lower guide wheel installed below, the steel cables on both sides are guided by the upper and lower guide wheels. The balance wheel synchronously adjusts and balances the steel cables on both sides, ensuring the balance of the lower mounting plate driving the boom. This facilitates stable opening and closing of the gate by the boom. Simultaneously, a second gear is fixedly connected to the outer wall of the rotating shaft. The meshing of the second gear with the first gear, and the meshing of a gear disc below the first gear, synchronously drives the connecting... The rod rotates, and a reciprocating screw is fixedly connected to one end of the connecting rod. A gear rack is connected to the surface of the reciprocating screw via a ball nut. Through the meshing of the gear rack with the first gear, the movable rod drives the gear column to move synchronously. Simultaneously, the symmetrical meshing of racks at the upper and lower ends of the gear column causes the two racks to drive the guide plates to move in opposite directions. By passing the steel cable through the guide plate, the guide plate moves synchronously with the rotation of the cable drum, guiding and unwinding the steel cable, ensuring the quality of the cable winding on the surface of the cable drum. Furthermore, a fixed cylinder is fixedly connected to the surface of the guide plate, and the main gear is rotatably connected inside the fixed cylinder. When the guide plate moves the fixed cylinder, the main gear rotates synchronously through meshing with the gear plate. A driven gear meshes with the outer wall of the main gear, allowing the driven gear to synchronously drive the rotating frame to rotate inside the fixed cylinder. The wave-like action of the rotating frame causes it to compress and expand the oil injection beads. An oil-absorbing sponge is fixedly connected to one side of the oil injection beads, allowing the sponge to absorb oil within the oil cavity during expansion and contraction. A sealing plate is fixedly connected to one end of the oil-absorbing sponge, ensuring the oil cavity remains sealed when the sponge is not absorbing oil. Additionally, a gear ring is fixedly connected to the upper outer wall of the rotating frame. The meshing connection between the gear ring and the No. 3 gear enables the No. 3 gear to rotate synchronously. Furthermore, with the second bevel gear fixedly connected to the top of the rotating column, the meshing connection between the first and second bevel gears enables the first bevel gear to synchronously drive the No. 2 gear to rotate. The meshing connection between the No. 2 gear and the rack enables the rack to drive the top ring to rise and fall, causing the top ring to drive the piston to extend and retract inside the oil chamber. This facilitates the compression of the lubricating oil inside the oil chamber, increasing the pressure and ensuring that the lubricating oil is fully absorbed by the oil-absorbing sponge. Moreover, it has good transmission performance and high synchronization effect, achieving efficient synchronous oil injection and lubrication of the steel cable during pulling, ensuring sufficient oil injection and lubrication effect of the steel cable inside the oil injection assembly.

[0014] The lower guide wheel has two parallel guide grooves, and a fixed rod is rotatably connected inside the lower guide wheel. Both ends of the fixed rod are fixedly connected to mounting plates. A hanging rod is fixedly connected inside the lower part of the mounting plate, and the hanging rod and the fixed rod are perpendicular to each other.

[0015] With the above structure, by opening two cable guide grooves on the outer wall of the lower guide wheel, the steel cable can be sleeved on the bottom end of the lower guide wheel through the upper guide wheel and the balance wheel. Moreover, under the action of the two lower guide wheels, the synchronous guidance and balance of the steel cables on both sides of the cable drum are ensured. Furthermore, the arrangement of the upper guide wheel, lower guide wheel and balance wheel reduces friction, distributes the force of the bottom lower guide wheel, helps to extend the service life of the drive motor, and ensures the stability of the gate lifting and lowering driven by the lower boom.

[0016] The balance wheel is rotatably connected to two side plates, which are fixedly connected to the bottom of the frame. The balance wheel and the upper guide wheel are perpendicular to each other. The upper guide wheel is provided with two steel cables on both sides of the cable drum.

[0017] Both sides of the upper guide wheel are rotatably connected to a first side plate, which is fixedly installed at the bottom of the frame.

[0018] By adopting the above structure, the second side plate and the first side plate are set to ensure that the upper guide wheel and the balance wheel are installed in a stable position below the frame. Moreover, the vertical distribution of the upper guide wheel and the balance wheel allows the steel cables on both sides of the cable drum to be adjusted horizontally in a balanced manner through the balance wheel, ensuring the balance of the steel cables in driving the hydraulic gate to rise and fall. In addition, the structure is simple and achieves a labor-saving effect of stable and balanced steel cable.

[0019] The transmission unit includes a first gear, which is fixedly connected to the end of the movable rod away from the gear post. The bottom end of the first gear is meshed with a gear rack, and the bottom of the gear rack is connected to a reciprocating screw through a ball nut. The bottom end of the gear rack is slidably connected to the surface of the frame, and the reciprocating screw is rotatably connected to the surface of the frame.

[0020] One end of the reciprocating lead screw is fixedly connected to a connecting rod, and the connecting rod is rotatably mounted on the surface of the frame. The outer end of the connecting rod is fixedly connected to a gear disk, the top end of the gear disk is meshed with a first gear, and the first gear is rotatably connected to the outside of the frame. The top end of the first gear is meshed with a second gear, the second gear is fixedly connected to the outer wall of the rotating shaft, and the second gear is located on the outside of the frame.

[0021] With the above structure, the meshing connection between the rack and the first gear allows the connecting rod to synchronously drive the reciprocating screw to rotate. This, in turn, causes the reciprocating screw to drive the rack in a reciprocating motion, which in turn drives the gear column to rotate synchronously via the movable rod. Furthermore, considering the co-directional rotation of the movable rod and the rotating shaft, the first gear is rotatably connected to the outside of the frame. Under the meshing action of the first gear, the second gear, and the gear disc, the second gear rotates synchronously with the gear disc. This allows the movable rod to rotate synchronously with the rotating shaft, facilitating the synchronous extension and retraction of the steel cable via the gear column and the rack.

[0022] The top of the frame is fixedly connected to a top plate, and the top of the top plate is threaded with multiple bolts, the top of which is threaded with a pre-embedded plate.

[0023] The embedded plate is distributed parallel to the top plate.

[0024] Using the above structure, the embedded plate is pre-embedded in the concrete beam, and the top plate is fixedly connected to the embedded plate with bolts. During installation, an anti-corrosion coating is painted on the surface of the embedded plate and the top plate to ensure the anti-corrosion effect of the top plate and the embedded plate. Moreover, the installation of the bottom frame is carried out by the top plate, which makes the overall hoisting machine easy and stable to install with the concrete beam, ensuring the installation flexibility and construction convenience of the hoisting machine.

[0025] The two guide plates are arranged in parallel, and the inside of the guide plates is provided with through holes that can accommodate steel cables. A fixing cylinder is fixedly connected to the surface of the through holes.

[0026] By adopting the above structure and setting the two guide plates in parallel, the rack can drive the two guide plates to move synchronously and symmetrically through the rotation of the gear column. This allows the guide plates to guide the two steel cables synchronously on the outer wall of the cable drum through the through holes, ensuring the winding and guiding effect of the steel cables on the outer wall of the cable drum.

[0027] The bottom end of the top ring is fixedly connected to a toothed rod, and the outer wall of the toothed rod is meshed with a second gear. The second gear is rotatably connected to the surface of the fixed cylinder. The outer wall of the second gear is fixedly connected to a first bevel gear, and the bottom end of the first bevel gear is meshed with a second bevel gear. The bottom end of the second bevel gear is fixedly installed with a rotating column, and the outer wall of the rotating column is fixedly connected to a third gear.

[0028] The outer wall of the No. 3 gear is meshed with a gear ring, which is fixedly sleeved on the outer wall of the rotating frame.

[0029] With the above structure, a rack is fixedly connected to the bottom of the top ring. Through the meshing of the first and second bevel gears, the rack and gear ring are synchronously driven. The fixed connection between the gear ring and the rotating frame allows the rotating frame to synchronously drive the gear ring to rotate when the gears rotate. This causes the rack to synchronously drive the top ring to move up and down above the fixed cylinder. A vertical rod and piston are fixedly connected to the bottom of the top ring, allowing the piston to extend and retract within the oil chamber. This facilitates the compression of the lubricating oil inside the oil chamber. When the rotating frame rotates and compresses the oil injection beads, the oil injection beads simultaneously pull the oil-absorbing sponge into the oil chamber to absorb oil. Pressure is simultaneously applied inside the oil chamber, ensuring the oil absorption quality of the oil-absorbing sponge and facilitating precise and efficient lubrication of the steel cable by the oil injection beads.

[0030] The top of the rotating frame is arranged in a ring-shaped wave pattern, and the inside of the rotating frame is provided with a ring-shaped through hole that can accommodate the expansion and contraction of oil beads.

[0031] The outer wall of the oil-absorbing sponge is fitted with a telescopic tube, and the telescopic tube is fixedly connected to the inner wall of the fixed cylinder.

[0032] With the above structure, the wavy design of the rotating frame allows it to compress the oil injection beads and expand and contract during rotation. Furthermore, by sleeved with a telescopic tube on the outer wall of the oil-absorbing sponge, and fixing the two ends of the telescopic tube to the fixed cylinder and the oil injection beads respectively, the oil injection beads can drive the telescopic tube to expand and contract stably on the outer wall of the oil-absorbing sponge during expansion and contraction. This facilitates stable expansion and contraction of the oil-absorbing sponge on one side of the oil cavity. Moreover, by fixing a sealing plate to one side of the oil-absorbing sponge, the sealing plate can be closed on one side of the oil cavity, ensuring the sealing of the inner wall of the oil cavity.

[0033] Compared with the prior art, the mobile suspended gate hoist of the present invention has the following advantages:

[0034] 1. In this invention, by fixing a fixed frame to the surface of the frame, and with the action of symmetrically arranged racks, the racks can guide the steel cable synchronously through the guide plate when the cable drum is winding. Furthermore, by fixing an oil injection component to the surface of the guide plate, the guide plate can simultaneously inject oil into the surface of the steel cable during guidance. With this arrangement, the hoist can drive the steel cable to perform stable and precise winding and unwinding during operation, ensuring the accuracy of the steel cable opening and closing. Moreover, the oil lubrication effect during the movement of the steel cable allows for synchronous oil lubrication, greatly facilitating the maintenance of the steel cable and improving its lubricity during movement, thus ensuring the accuracy of the steel cable movement.

[0035] 2. In this invention, by rotating the movable rod above the fixed frame, and with the reciprocating screw fixedly connected to the outer wall of the movable rod, the connecting rod is synchronously driven by the gear and the gear rack through the meshing connection of the first gear and the first gear and the second gear via the gear disc. Furthermore, with the first gear meshing with the second gear and the gear disc, the second gear and the gear disc rotate synchronously in the same direction, allowing the rotating shaft to drive the movable rod to rotate in the same direction. This causes the gear column to drive the rack on the outer wall to extend and retract synchronously. With this arrangement, when the cable drum drives the steel cable to open and close, the movable rod synchronously drives the rack and guide plate to guide the steel cables on both sides to open and close synchronously, ensuring the winding effect of the steel cable on the surface of the cable drum, avoiding the problem of the steel cable tangling during winding and unwinding, and further improving the opening and closing balance and stability of the gate opener.

[0036] 3. In this invention, by fixing an oil injection component to the surface of the guide plate and rotating a main gear inside the fixed cylinder, the guide plate drives the oil injection component to move. The main gear rotates synchronously through meshing with the toothed plate. Furthermore, by meshing a driven gear on the outer wall of the main gear, the driven gear can synchronously drive the rotating frame to rotate. This facilitates the rotating frame to apply oil to the surface of the steel cable by squeezing the oil injection beads, achieving synchronous oil injection and lubrication when the steel cable moves inside the fixed cylinder. This ensures the lubrication of the steel cable during lifting and lowering, facilitates the maintenance and upkeep of the steel cable, and helps extend the service life of the steel cable.

[0037] 4. In this invention, a gear ring is fixedly connected to the top of the rotating frame. Under the meshing action of the first bevel gear and the second bevel gear, the rotating frame drives the top ring to move up and down synchronously when rotating. Under the action of the piston fixedly connected to the bottom of the top ring, the piston moves in and out of the oil chamber. This realizes that when the rotating frame rotates and squeezes the oil injection ball, the piston squeezes the lubricating oil in the oil chamber synchronously. When the oil injection ball is squeezed and drives the oil-absorbing sponge into the oil chamber to absorb oil, the piston simultaneously applies pressure to the lubricating oil in the oil chamber, ensuring the oil absorption quality of the oil-absorbing sponge and facilitating efficient oil injection and lubrication of the steel cable by the oil injection ball.

[0051] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0052] like Figures 1-12As shown, a mobile suspended gate hoist includes a frame 1, a rotating shaft 2 rotatably connected inside the frame 1, a drive motor 3 for driving the rotating shaft 2, and two cable drums 4 fixedly connected to the outer wall of the rotating shaft 2. To facilitate the installation of the frame 1, a top plate 14 is fixedly connected to the top of the frame 1, and multiple bolts 15 are threadedly connected to the top of the top plate 14. Embedded plates 16 are threadedly connected to the top of the bolts 15, and the embedded plates 16 are parallel to the top plate 14. The embedded plates 16 are pre-embedded in a concrete beam, and the top plate 14 and the embedded plates 16 are fixedly connected by the bolts 15. During installation, an anti-corrosion coating is applied to the surfaces of the embedded plates 16 and the top plate 14 to ensure their anti-corrosion effect. Furthermore, the top plate... 14. The bottom frame 1 is installed, making the hoist and concrete beam installation convenient and stable, ensuring the hoist's installation flexibility and ease of construction. Meanwhile, steel cables 5 are symmetrically wound on both outer walls of the cable drum 4. Upper guide wheels 6 are connected to the outer walls of the steel cables 5, located below the frame 1. First side plates 7 are rotatably connected to both sides of the upper guide wheels 6, which are fixedly installed at the bottom of the frame 1. The steel cables 5 are connected to lower guide wheels 8 from the top wall of the upper guide wheels 6. The lower guide wheels 8 have two parallel guide grooves. By opening two guide grooves on the outer wall of the lower guide wheels 8, the steel cables 5 can pass through the upper guide wheels 6 and be fitted onto the bottom of the lower guide wheels 8 via the balance wheel 11. Furthermore, under the action of the two lower guide wheels 8... This ensures the synchronous guidance and balance of the steel cables 5 on both sides of the winding drum 4. Simultaneously, to connect the hoist to the hydraulic gate, a fixed rod 9 is rotatably connected inside the lower guide wheel 8. Mounting plates 10 are fixedly connected to both ends of the fixed rod 9. A lifting rod 13 is fixedly connected to the lower interior of the mounting plate 10, and the lifting rod 13 is perpendicular to the fixed rod 9. A balance wheel 11 is installed above the lower guide wheel 8, rotatably connected to the lower part of the frame 1. The steel cables 5 on both sides are fitted in an inverted "U" shape onto the outer wall of the balance wheel 11. Second side plates 12 are rotatably connected to both sides of the balance wheel 11, and the second side plates 12 are fixedly connected to the bottom end of the frame 1. The balance wheel 11 is perpendicular to the upper guide wheel 6. The second side plates 12 connect to the first side plate... The arrangement of wheel 7 ensures the stability of the upper guide wheel 6 and the balance wheel 11 in their lower mounting positions below the frame 1. Furthermore, the vertical distribution of the upper guide wheel 6 and the balance wheel 11 allows the steel cables 5 on both sides of the cable drum 4 to be horizontally adjusted in a balanced manner via the balance wheel 11, ensuring the balance of the steel cables 5 in driving the hydraulic gate's lifting and lowering. This simple structure achieves a labor-saving effect by ensuring the stable balance of the steel cables 5. To achieve synchronous guiding of the steel cables 5 on both sides of the cable drum 4, two upper guide wheels 6 are correspondingly arranged for each steel cable 5 on both sides of the cable drum 4. This arrangement, under the action of the upper guide wheel 6, lower guide wheel 8, and balance wheel 11, reduces friction on the steel cables 5 during movement, distributing the force across the lower guide wheel 8 and extending the service life of the drive motor 3.This also ensured the stability of the gate's lifting and lowering driven by the lower boom 13;

[0053] A fixed frame 17 is fixedly connected to the surface of the frame 1. A movable rod 18 is rotatably connected above the fixed frame 17. The movable rod 18 is connected to the rotating shaft 2 via a transmission unit. The transmission unit includes a first gear 23, which is fixedly connected to the end of the movable rod 18 away from the gear post 19. A gear rack 24 is meshed at the bottom of the first gear 23. A reciprocating screw 25 is connected to the bottom of the gear rack 24 via a ball nut. The bottom of the gear rack 24 is slidably connected to the surface of the frame 1. The reciprocating screw 25 is rotatably connected to the surface of the frame 1. In order to realize the transmission drive of the reciprocating screw 25, a connecting rod 26 is fixedly connected to one end of the reciprocating screw 25. The connecting rod 26 is rotatably mounted on the machine. The surface of frame 1 is connected to gear 23 via a gear rack 24, allowing the connecting rod 26 to rotate synchronously with the reciprocating screw 25. This reciprocating screw 25 then drives the gear rack 24 to reciprocate, which in turn drives the gear column 19 to rotate synchronously via the movable rod 18. The sliding connection of the gear rack 24 on the surface of frame 1 ensures the precision of its sliding motion via the reciprocating screw 25, limiting the movement path of the gear rack 24. A gear disk 27 is fixedly connected to the outer end of the connecting rod 26, and a first gear 28 is meshed with the top of the gear disk 27. The first gear 28 is rotatably connected to the outside of frame 1. A second gear 29 is connected to the outer wall of the rotating shaft 2 and is located on the outside of the frame 1. A gear column 19 is fixedly connected to the outer wall of the movable rod 18, and two racks 20 are symmetrically connected to the upper and lower outer walls of the gear column 19. The racks 20 are slidably connected to the surface of the fixed frame 17, and a guide plate 21 is fixedly connected to the outer wall of the racks 20. The surface of the fixed frame 17 has a sliding groove 22 to accommodate the sliding of the racks 20. A first gear 28 is rotatably connected to the outside of the frame 1. Under the meshing action of the first gear 28, the second gear 29, and the gear disk 27, the second gear 29 and the gear disk 27 rotate synchronously in the same direction, thereby causing the movable rod 18 to rotate synchronously. It can rotate synchronously in the same direction with the rotating shaft 2, so that the movable rod 18 can drive the rack 20 through the gear column 19 to guide the steel cable 5 to extend and retract synchronously. The steel cable 5 is movably connected through the inside of the guide plate 21. Specifically, the two guide plates 21 are arranged in parallel, and the inside of the guide plate 21 is provided with a through hole that can accommodate the steel cable 5. The surface of the through hole is fixedly connected to the fixed cylinder 31. With the two guide plates 21 arranged in parallel, the rack 20 can drive the two guide plates 21 to move synchronously and symmetrically through the rotation of the gear column 19. This allows the guide plates 21 to guide the two steel cables 5 synchronously on the outer wall of the cable drum 4 through the through hole, ensuring the winding and guiding effect of the steel cable 5 on the outer wall of the cable drum 4.

[0054] Furthermore, toothed plates 30 are fixedly connected to both the upper and lower ends of the fixed frame 17, and the toothed plates 30 are arranged parallel to the rack 20. An oil injection assembly is connected to the outer wall of the toothed plates 30, and the oil injection assembly is fixedly connected to the surface of the guide plate 21. Specifically, the oil injection assembly includes a fixed cylinder 31, which is fixedly installed on the surface of the guide plate 21. A main gear 32 is rotatably connected inside the fixed cylinder 31, and a driven gear 33 is meshed with the outer wall of the main gear 32. A rotating frame 34 is fixedly connected to the inner wall of the driven gear 33, and the rotating frame 34 is rotatably connected inside the fixed cylinder 31. Multiple oil injection beads 35 are telescopically arranged above the rotating frame 34, and the upper part of the rotating frame 34 is arranged in an annular wave shape. Through the wave shape of the rotating frame 34, the rotating frame 34 can squeeze the oil injection beads 35 to perform telescopic movement when rotating. At the same time, a through hole is opened in the annular shape inside the rotating frame 34 to accommodate the telescopic movement of the oil injection beads 35. The effect is that a telescopic spring 36 is fixedly connected to one side of the oil injection bead 35, and the telescopic spring 36 is fixedly connected to the inner wall of the fixed cylinder 31. Multiple oil-absorbing sponges 37 are telescopically arranged inside the fixed cylinder 31. The oil-absorbing sponges 37 are fixedly connected to one side of the oil injection bead 35. The outer wall of the oil-absorbing sponge 37 is fitted with a telescopic tube, and the telescopic tube is fixedly connected to the inner wall of the fixed cylinder 31. A sealing plate 38 is fixedly connected to the end of the oil-absorbing sponge 37 away from the oil injection bead 35. Under the action of the telescopic tube fitted to the outer wall of the oil-absorbing sponge 37, the two ends of the telescopic tube are fixed to the fixed cylinder 31 and the oil injection bead 35 respectively, so that when the oil injection bead 35 telescopically extends and retracts, it drives the telescopic tube to stably extend and retract on the outer wall of the oil-absorbing sponge 37, which facilitates the stable extension and retraction of the oil-absorbing sponge 37 on one side of the oil cavity. Moreover, by fixing the sealing plate 38 to one side of the oil-absorbing sponge 37, the sealing plate 38 can be closed on one side of the oil cavity, ensuring the sealing of the inner wall of the oil cavity.

[0055] Furthermore, an oil chamber is connected above the fixed cylinder 31. The oil chamber has an annular structure, and a piston 39 is telescopically connected inside the oil chamber. A vertical rod 40 is fixedly connected to the top of the piston 39, and a top ring 41 is fixedly connected to the top of the vertical rod 40. A gear 42 is fixedly connected to the bottom of the top ring 41. A second gear 43 is meshed with the outer wall of the gear 42. The second gear 43 is rotatably connected to the surface of the fixed cylinder 31. A first bevel gear 44 is fixedly connected to the outer wall of the second gear 43. A second bevel gear 45 is meshed with the bottom of the first bevel gear 44. A rotating column 46 is fixedly installed at the bottom of the second bevel gear 45, and a third gear 47 is fixedly connected to the outer wall of the rotating column 46. A gear ring 48 is meshed with the outer wall of the third gear 47. The gear ring 48 is fixedly sleeved on the outer wall of the rotating frame 34. The gear 42 is fixedly connected to the bottom of the top ring 41. With the meshing action of the first bevel gear 44 and the second bevel gear 45, the rack 42 and the gear ring 48 are synchronously transmitted. Through the fixed connection between the gear ring 48 and the rotating frame 34, the rotating frame 34 drives the gear ring 48 to rotate synchronously when the driven gear 33 rotates. This causes the rack 42 to synchronously drive the top ring 41 to move up and down above the fixed cylinder 31. By fixing the upright rod 40 and the piston 39 to the bottom end of the top ring 41, the piston 39 can move in and out inside the oil chamber, which facilitates the compression of the lubricating oil inside the oil chamber. When the rotating frame 34 rotates and compresses the oil injection ball 35, the oil injection ball 35 simultaneously drives the oil-absorbing sponge 37 into the oil chamber to absorb oil. Pressure is applied inside the oil chamber at the same time, ensuring the oil absorption quality of the oil-absorbing sponge 37 and facilitating the precise and efficient oil injection lubrication of the steel cable 5 by the oil injection ball 35.

[0056] The working principle of this invention is as follows: During use, the drive motor 3 is energized, causing the rotating shaft 2 to rotate. This causes the winding drum 4 to wind and unwind the steel cable 5 on the outer wall. With the upper guide wheel 6 and balance wheel 11 positioned below the frame 1, and the lower guide wheel 8 positioned below, the steel cables 5 on both sides are guided by the upper guide wheel 6 and lower guide wheel 8. The balance wheel 11 synchronously adjusts and balances the steel cables 5 on both sides, ensuring the balance of the lower mounting plate 10 driving the boom 13. This facilitates the stable opening and closing of the gate by the boom 13. Simultaneously, a second gear 29 is fixedly connected to the outer wall of the rotating shaft 2. The meshing of the second gear 29 with the first gear 28, and the meshing of the gear disc 27 below the first gear 28, causes the rotating shaft... 2. The connecting rod 26 is rotated synchronously. A reciprocating screw 25 is fixedly connected to one end of the connecting rod 26. Under the action of the gear rack 24 connected to the surface of the reciprocating screw 25 through the ball nut, the gear rack 24 meshes with the first gear 23, causing the movable rod 18 to drive the gear column 19 to move synchronously. At the same time, under the action of the symmetrical meshing of the racks 20 at the upper and lower ends of the gear column 19, the two racks 20 drive the guide plate 21 to move in opposite directions or away from each other. By passing the steel cable 5 through the inside of the guide plate 21, the guide plate 21 moves synchronously when the cable drum 4 rotates to guide and wind the steel cable 5, ensuring the winding quality of the steel cable 5 on the surface of the cable drum 4. Moreover, by fixing the fixed cylinder 31 to the surface of the guide plate 21, the... Under the action of the main gear 32 rotating inside the fixed cylinder 31, the guide plate 21 drives the fixed cylinder 31 to move. The main gear 32 rotates synchronously through meshing with the toothed plate 30. Furthermore, through the meshing of the driven gear 33 with the outer wall of the main gear 32, the driven gear 33 can synchronously drive the rotating frame 34 to rotate inside the fixed cylinder 31. With the rotating frame 34 exhibiting a wave-like action, it can compress the oil injection beads 35 during rotation, allowing them to extend and retract. By fixing an oil-absorbing sponge 37 to one side of the oil injection beads 35, the oil injection beads 35 synchronously drive the oil-absorbing sponge 37 to absorb oil inside the oil cavity during extension and retraction. Moreover, by fixing a sealing plate 38 to one end of the oil-absorbing sponge 37, it is ensured that the oil-absorbing sponge 37 does not... The oil chamber is sealed during oil suction. Simultaneously, a gear ring 48 is fixedly connected to the upper outer wall of the rotating frame 34. The gear ring 48 meshes with the third gear 47, causing the third gear 47 to rotate synchronously. Furthermore, a second bevel gear 45 is fixedly connected to the top of the rotating column 46. The meshing of the first bevel gear 44 and the second bevel gear 45 causes the first bevel gear 44 to synchronously drive the second gear 43 to rotate. The meshing of the second gear 43 with the rack 42 causes the rack 42 to drive the top ring 41 to rise and fall. This causes the top ring 41 to drive the piston 39 to extend and retract within the oil chamber, facilitating the compression of the lubricating oil inside the chamber and increasing pressure. This ensures the lubricating oil is fully absorbed by the oil-absorbing sponge 37, and provides good transmission performance.The high synchronization effect enables efficient synchronous oil injection and lubrication of the steel cable 5 during pulling, ensuring sufficient oil injection and lubrication within the oil injection assembly. This completes the working principle of the mobile suspended gate hoist.

[0057] In summary, in this invention, by fixing the fixing frame 17 to the surface of the frame 1, and under the action of the symmetrically arranged racks 20, the racks 20 can guide the steel cable 5 synchronously through the guide plate 21 when the cable drum 4 is winding. Moreover, by fixing the oil injection component to the surface of the guide plate 21, the guide plate 21 can simultaneously inject oil into the surface of the steel cable 5 during guidance. With this setting, the hoist can drive the steel cable 5 to perform stable and precise winding and unwinding during operation, ensuring the opening and closing accuracy of the steel cable 5. Furthermore, the oil lubrication effect of the steel cable 5 during movement allows for synchronous oil lubrication during movement, greatly facilitating the maintenance of the steel cable 5 and improving its lubricity during movement, thus ensuring the movement accuracy of the steel cable 5. This solves the technical problems of current mobile suspended hoists being unable to effectively guide and store the steel cable 5, and unable to perform convenient lubrication and maintenance, resulting in poor working quality and poor balance of the steel cable 5.
