Description

Technical Field

[0001] The present invention relates to the technical field of lifting equipment, and particularly relates to a winch-type hose hoist. Background Art

[0002] A winch-type hose hoist is a device that uses the winch principle for lifting operations. It winds and releases the hose through a drum and a driving device (such as an electric motor, manual or hydraulic power), thereby realizing the functions of lifting and moving heavy objects. The basic principle of a winch-type hose hoist is to use ropes, steel cables or other similar objects as the lifting medium, and wind and release these media through a drum set at a fixed position. The driving device provides power to rotate the drum, thereby lifting or moving heavy objects.

[0003] In the prior art, when a winch-type hose hoist is in use, a hook is usually used to fixedly hang one end of the hose to be moved for transportation. Then, during the lifting process, the other end of the hose is not limited and fixed, so it will swing due to moving inertia or external force factors. Then, when the lifted hose is used for docking, the swing of the pipe interface will directly cause the flange end face to be not perpendicular to the pipe axis, making the joint surface unable to fit tightly, thereby causing medium leakage problems and affecting its subsequent use effect. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a winch-type hose hoist to solve the problems raised in the above background art.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A winch-type hose hoist, including a base platform, the top surface of the base platform is rotatably connected with a boom, a support column is arranged on the bottom surface of the boom, an electric winch is fixedly installed on the top surface of the boom, a main steel cable is wound inside the electric winch, one end of the main steel cable is fixedly installed with a main hook, a first hydraulic rod is fixedly installed on one side of the base platform, and one end of the first hydraulic rod is rotatably connected with the boom;

[0007] Sliding rails are respectively fixedly installed on both sides of the boom, the inner wall surface of the sliding rail is an inclined surface, a slider is slidably connected inside the sliding rail, a connecting plate is fixedly installed on one side of the slider, a second adjusting rod is rotatably connected inside the connecting plate, one end of the second adjusting rod is rotatably connected with a first adjusting rod, a mounting head is fixedly installed at one end of the first adjusting rod, the other end of the first adjusting rod is rotatably connected with the boom, a positioning cover is fixedly installed on the top surface of the mounting head, two limiting wheels are rotatably connected inside the positioning cover, a secondary steel cable is arranged between the two limiting wheels, and one end of the secondary steel cable is fixedly installed with a secondary hook;

[0008] A driving component is arranged on the bottom surface of the boom and is used to drive the retraction and extension of the two auxiliary steel cables.

[0009] An adjusting component is arranged on the bottom surface of the boom and is used to adjust the use angles of the two first adjusting rods.

[0010] By adopting the above technical solution, during use, the staff adjusts the lengths of the two auxiliary steel cables by using the adjusting component and the driving component according to the length of the hose to be lifted. At the same time, the two first adjusting rods are rotated and opened. Then, the driving component is continuously used to release the two auxiliary steel cables. Further, under the action of the weight of the auxiliary hook, the auxiliary hook will droop to the same height as the main hook, so as to calibrate the use heights of the two auxiliary hooks and the main hook. After the above steps are completed, the staff hangs the main hook on the middle part of the hose and hangs the two auxiliary hooks on both ends of the hose respectively. Then, the staff jacks up the boom through the first hydraulic rod, and at the same time, the two auxiliary steel cables drive the auxiliary hook to move upward to adjust the heights of both ends of the hose through the driving component. And the second protective cover contracts the main steel cable to make the main hook rise, so as to complete the lifting of the hose. During this process, since the use spacing of the two auxiliary hooks can be adjusted according to the length of the hose, and at the same time, since both ends of the hose are limited to a certain extent during the lifting process, the yaw of both ends of the hose during lifting can be reduced, preventing the occurrence of axis deviation during subsequent docking use.

[0011] Preferably, the driving component includes: a mounting plate fixedly installed on the bottom surface of the boom. Two bearing seats are fixedly installed on the top surface of the mounting plate. A receiving wheel is rotatably connected inside the bearing seat. The inner wall surface of the receiving wheel is wound and connected with the auxiliary steel cable. A driving motor is fixedly installed on the bottom surface of the boom. One end of the driving shaft of the driving motor is fixedly installed with a driving transmission gear. Two driving sprockets are rotatably connected to the bottom surface of the mounting plate. One side of the driving sprocket is fixedly installed with a driven transmission gear. The driven transmission gear is meshed and connected with the driving transmission gear. One side of the receiving wheel is fixedly installed with a driven sprocket. A transmission chain is arranged between the driven sprocket and the driving sprocket. The driving sprocket and the driven sprocket are drivingly connected through the transmission chain.

[0012] By adopting the above technical solution, when the staff uses the two auxiliary hooks, the staff starts the driving motor. Then, the rotation of the driving shaft of the driving motor will drive the driving transmission gear to rotate. Then, under the meshing transmission of the driving transmission gear and the driven transmission gear, the two driving sprockets will rotate accordingly. At this time, under the chain drive of the driving sprocket, the transmission chain and the driven sprocket, the two driven sprockets will respectively drive the two receiving wheels to rotate. Further, the rotation of the receiving wheel will wind or release the auxiliary steel cable inside it, so as to achieve the effect of driving and using the two auxiliary hooks.

[0013] Preferably, the adjusting assembly includes: a second hydraulic rod fixedly installed on the bottom surface of the boom. One end of the telescopic rod of the second hydraulic rod is rotatably connected to an adapter seat. Two positioning rods are slidably connected inside the adapter seat. A spring is movably sleeved on the outer wall surface of the positioning rods. One ends of the two positioning rods are respectively fixedly installed on one side of the two connecting plates.

[0014] By adopting the above technical solution, when the staff uses the two first adjusting rods, the staff starts the second hydraulic rod. Then, the retraction of the telescopic rod of the second hydraulic rod will drive the adapter seat to move. Subsequently, the moving adapter seat will drive the two connecting plates to move, and the two sliders will slide inside the two slide rails. At the same time, the two positioning rods will extend out of the adapter seat and squeeze the spring. At this time, since the inner walls of the two slide rails are inclined surfaces, the sliding of the sliders will cause the connecting plates to drive the second adjusting rod to rotate. Then, the rotating second adjusting rod will push the first adjusting rod to rotate. At this time, the use distance between the two first adjusting rods will open away from each other. Then, the mounting heads at one ends of the two first adjusting rods will drive the positioning covers on their tops and the auxiliary steel cables inside the limit wheels to move, so as to adjust the use distance between the two auxiliary hooks.

[0015] Preferably, limiting tubes are respectively fixedly installed on both sides of the boom. A sliding rod is slidably connected inside the limiting tube. One end of the sliding rod is rotatably connected to a connecting head. The inner wall surface of the connecting head is fixedly sleeved with the first adjusting rod. A fixing frame is fixedly installed on the bottom surface of the boom. The inner wall surface of the fixing frame is fixedly sleeved with the limiting tube.

[0016] By adopting the above technical solution, when the two first adjusting rods move away and open, the two sliding rods will slide out of the limiting tubes under the drive of the connecting head. Then, the fixing frame at the bottom of the boom will support the two limiting tubes. Then, under the force conduction of the limiting tubes and the fixing frame, the bearing capacity of the two first adjusting rods during use can be improved.

[0017] Preferably, mounting seats are respectively fixedly installed on both sides of the boom. A wire reel is rotatably connected inside the mounting seat. A torsion spring is fixedly sleeved on the outer wall surface of the shaft of the wire reel. A steel wire rope is wound inside the wire reel. One end of the steel wire rope is fixedly installed on the mounting head.

[0018] By adopting the above technical solution, when the two first adjusting rods drive the two mounting heads to move, the mounting heads will pull the steel wire rope. Then, the pulled steel wire rope will drive the wire reel to rotate. At this time, under the resilience of the torsion spring, the steel wire rope can generate a certain pulling force on the mounting head, so as to position the use angle of the mounting head and prevent it from being deflected and causing the auxiliary steel cable inside it to fall off.

[0019] Preferably, a tensioning seat is rotatably connected to one side of the mounting head. Two tensioning wheels are rotatably connected inside the tensioning seat. Second elastic telescopic rods are respectively rotatably connected to both sides of the tensioning seat. One end of the second elastic telescopic rod is rotatably connected to the positioning cover.

[0020] By adopting the above technical solution, under the action of the resilience of the two second elastic telescopic rods, the tensioning seat can drive the two tensioning wheels inside it to press down on the auxiliary steel cable, so that the auxiliary steel cable maintains a certain tension during use and prevents it from falling off between the two limiting wheels.

[0021] Preferably, positioning seats are respectively fixedly installed on both sides of the boom. A mounting sleeve is fixedly installed on one side of the positioning seat. Two positioning wheels are rotatably connected inside the mounting sleeve.

[0022] By adopting the above technical solution, it is convenient to limit the auxiliary steel cable during its retraction and extension, and prevent the auxiliary steel cable from falling off between the storage wheel.

[0023] Preferably, mounting plates are respectively fixedly installed on both sides of the boom. A connecting rod is rotatably connected to one side of the mounting plate. One end of the connecting rod is rotatably connected to a pressing wheel. A first elastic telescopic rod is fixedly installed on one side of the mounting plate. One end of the retractable rod of the first elastic telescopic rod is fixedly installed with the connecting rod.

[0024] By adopting the above technical solution, the resilience of the first elastic telescopic rod drives the pressing wheel to squeeze the steel wire rope, so that the steel wire rope maintains a certain tension and prevents the steel wire rope from falling off inside the wire take-up wheel.

[0025] Preferably, a second protective cover is rotatably connected to the top surface of the boom, and a first protective cover is rotatably connected to the bottom surface of the boom.

[0026] By adopting the above technical solution, it is convenient to protect the drive motor and the electric winch.

[0027] In summary, the present invention mainly has the following beneficial effects:

During use, the staff adjusts the lengths of the two secondary steel cables 18 according to the length of the hose to be hoisted by using the adjusting assembly and the driving assembly, and at the same time makes the two first adjusting rods 13 rotate and open. Then, the driving assembly is continuously used to release the two secondary steel cables 18. Further, under the action of the weight of the secondary hook 19, the secondary hook 19 will droop to the same height as the main hook 4, so as to calibrate the use heights of the two secondary hooks 19 and the main hook 4. After the above steps are completed, the staff hangs the main hook 4 on the middle part of the hose, and respectively hangs the two secondary hooks 19 on both ends of the hose. Then, the staff jacks up the boom 2 through the first hydraulic rod 6, and at the same time drives the two secondary steel cables 18 through the driving assembly to drive the secondary hooks 19 to move upward to adjust the heights of both ends of the hose. And the second protective cover 10 contracts the main steel cable 3 to make the main hook 4 rise, so as to complete the hoisting of the hose. During this process, since the use spacing of the two secondary hooks 19 can be adjusted according to the length of the hose, and at the same time, since both ends of the hose are limited to a certain extent during hoisting, the yaw of both ends of the hose during hoisting can be reduced, and the effect of preventing the axis deviation during subsequent butt joint use can be achieved.

[0048] Based on the above embodiment, refer to Figure 2 and Figure 10The driving assembly includes: a mounting plate 8, the mounting plate 8 is fixedly mounted on the bottom surface of the boom 2, two bearing seats 38 are fixedly mounted on the top surface of the mounting plate 8, a storage wheel 39 is rotatably connected inside the bearing seat 38, and the inner wall surface of the storage wheel 39 is connected to the auxiliary steel cable 18 by winding, a driving motor 44 is fixedly mounted on the bottom surface of the boom 2, a driving transmission tooth 45 is fixedly mounted on one end of the driving shaft of the driving motor 44, two driving sprockets 42 are rotatably connected to the bottom surface of the mounting plate 8, a driven transmission tooth 43 is fixedly mounted on one side of the driving sprocket 42, and the driven transmission tooth 43 is meshed with the driving transmission tooth 45, a driven sprocket 40 is fixedly mounted on one side of the storage wheel 39, and a transmission chain is arranged between the driven sprocket 40 and the driving sprocket 42. 41, the driving sprocket 42 and the driven sprocket 40 are connected through the transmission chain 41. When the staff uses the two auxiliary hooks 19, the staff starts the driving motor 44, and the rotation of the driving shaft of the driving motor 44 will drive the driving transmission teeth 45 to rotate, and then under the tooth meshing transmission action of the driving transmission teeth 45 and the driven transmission teeth 43, the two driving sprockets 42 will rotate accordingly. At this time, under the chain transmission action of the driving sprocket 42, the transmission chain 41 and the driven sprocket 40, the two driven sprockets 40 will respectively drive the two receiving wheels 39 to rotate, and then the rotation of the receiving wheel 39 will reel in or release the auxiliary steel cable 18 inside it, thereby achieving the effect of driving the two auxiliary hooks 19.

[0049] Based on the above embodiments, reference Figure 2 , Figure 3 , Figure 4 and Figure 5, the adjustment assembly includes: a second hydraulic rod 7, which is fixedly installed on the bottom surface of the boom 2. One end of the telescopic rod of the second hydraulic rod 7 is rotatably connected to an adapter seat 35. Two positioning rods 36 are slidably connected inside the adapter seat 35. A spring 37 is movably sleeved on the outer wall surface of the positioning rod 36. One ends of the two positioning rods 36 are respectively fixedly installed on one side of the two connecting plates 15. When the staff uses the two first adjusting rods 13, the staff starts the second hydraulic rod 7. Then, the retraction of the telescopic rod of the second hydraulic rod 7 will drive the adapter seat 35 to move. Then, the moving adapter seat 35 will drive the two connecting plates 15 to move, and make the two sliders 34 slide inside the two slide rails 12. At the same time, the two positioning rods 36 will extend out of the adapter seat 35 and squeeze the spring 37. At this time, since the inner walls of the two slide rails 12 are inclined surfaces, the sliding of the sliders 34 will cause the connecting plates 15 to drive the second adjusting rod 14 to rotate. Then, the rotating second adjusting rod 14 will push the first adjusting rod 13 to rotate. At this time, the use spacing of the two first adjusting rods 13 will move away from each other and open. Then, the mounting heads 46 at one ends of the two first adjusting rods 13 will drive the positioning covers 47 on their tops and the auxiliary steel cables 18 inside the limiting wheels 48 to move, so as to adjust the use spacing of the two auxiliary hooks 19. Limiting tubes 22 are respectively fixedly installed on both sides of the boom 2. A slide rod 23 is slidably connected inside the limiting tube 22. One end of the slide rod 23 is rotatably connected to a connecting head 24. The inner wall surface of the connecting head 24 is fixedly sleeved with the first adjusting rod 13. A fixing frame 17 is fixedly installed on the bottom surface of the boom 2. The inner wall surface of the fixing frame 17 is fixedly sleeved with the limiting tube 22. When the two first adjusting rods 13 move away and open, the two slide rods 23 will be driven by the connecting head 24 to slide out of the limiting tube 22. Then, the fixing frame 17 at the bottom of the boom 2 will support the two limiting tubes 22. Then, under the force transmission of the limiting tube 22 and the fixing frame 17, the bearing capacity of the two first adjusting rods 13 during use can be improved.

[0050] Based on the above embodiment, refer to Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9, mounting seats 21 are fixedly installed on both sides of the jib 2. A wire reel 25 is rotatably connected inside the mounting seat 21. A torsion spring 26 is fixedly sleeved on the outer wall surface of the rotating shaft of the wire reel 25. A steel wire rope 27 is wound inside the wire reel 25. One end of the steel wire rope 27 is fixedly installed with a mounting head 46. When the two first adjusting rods 13 drive the two mounting heads 46 to move, the mounting head 46 will pull the steel wire rope 27, and then the pulled steel wire rope 27 will drive the wire reel 25 to rotate. At this time, under the action of the restoring force of the torsion spring 26, the steel wire rope 27 can generate a certain pulling force on the mounting head 46, so as to position the use angle of the mounting head 46 and prevent it from being displaced and causing the secondary steel cable 18 inside it to fall off. One side of the mounting head 46 is rotatably connected with a tensioning seat 49. Two tensioning wheels 28 are rotatably connected inside the tensioning seat 49. Two second elastic telescopic rods 50 are rotatably connected to both sides of the tensioning seat 49. One end of the second elastic telescopic rod 50 is rotatably connected with the positioning cover 47. Through the action of the restoring force of the two second elastic telescopic rods 50, the tensioning seat 49 can drive the two tensioning wheels 28 inside it to press down on the secondary steel cable 18, so that the secondary steel cable 18 maintains a certain tension during use and prevents it from falling off between the two limiting wheels 48. Positioning seats 16 are fixedly installed on both sides of the jib 2. A mounting sleeve 32 is fixedly installed on one side of the positioning seat 16. Two positioning wheels 33 are rotatably connected inside the mounting sleeve 32, which is convenient for limiting the secondary steel cable 18 during its retraction and extension to prevent the secondary steel cable 18 from falling off between the storage reel 39. Mounting plates 20 are fixedly installed on both sides of the jib 2. One side of the mounting plate 20 is rotatably connected with a connecting rod 30. One end of the connecting rod 30 is rotatably connected with a pressing wheel 31. A first elastic telescopic rod 29 is fixedly installed on one side of the mounting plate 20. One end of the retractable rod of the first elastic telescopic rod 29 is fixedly installed with the connecting rod 30. Through the restoring force of the first elastic telescopic rod 29, the pressing wheel 31 is driven to squeeze the steel wire rope 27, so that the steel wire rope 27 maintains a certain tension and prevents the steel wire rope 27 from falling off from inside the wire reel 25. A second protective cover 10 is rotatably connected to the top surface of the jib 2, and a first protective cover 9 is rotatably connected to the bottom surface of the jib 2, which is convenient for protecting the drive motor 44 and the electric winch 11.

[0051] The controller inside the control box on the outside of the base platform 1 activates the second hydraulic rod 7. Furthermore, the retraction of the telescopic rod of the second hydraulic rod 7 drives the connecting seat 35 to move. Then, the two connecting plates 15 will move accordingly and drive the two second adjusting rods 14 to rotate. Then, the rotating second adjusting rods 14 will push the two first adjusting rods 13 to rotate and open for use. The controller inside the control box on the outside of the base platform 1 activates the drive motor 44 to rotate the two storage wheels 39 to release the two auxiliary steel cables 18. At the same time, the controller inside the control box activates the electric winch 11 to release the main steel cable 3. In this way, the two auxiliary hooks 19 and the main hook 4 will drop to the same height as the hose. At this time, the two ends and the middle of the hose are fixed by the main hook 4 and the two auxiliary hooks 19. Then, the controller inside the control box reverses the drive shaft of the drive motor 44, thereby driving the two storage wheels 39 to wind up the two auxiliary steel cables 18. At the same time, the controller of the base platform 1 makes the electric winch 11 wind up the main steel cable 3. In this way, the two auxiliary hooks 19 and the main hook 4 can drive the hose to rise simultaneously, thereby initially lifting the hose. At this time, the first hydraulic rod 6 is used through the controller to make its telescopic rod drive the boom 2 to rotate, completing the further lifting of the hose.

[0052] Working principle: Please refer to Figures 1 - 11 As shown, during use, the staff adjusts the length of the hose to be lifted and uses the adjustment component and the drive component to release the two auxiliary steel cables 18. At the same time, the two first adjusting rods 13 are rotated and opened. Then, the drive component is continued to be used to release the two auxiliary steel cables 18. Then, under the action of the weight of the auxiliary hook 19, the auxiliary hook 19 will droop to the same height as the main hook 4, thereby calibrating the use height of the two auxiliary hooks 19 and the main hook 4. After the above steps are completed, the staff hangs the main hook 4 on the middle part of the hose and hangs the two auxiliary hooks 19 on the two ends of the hose respectively. Then, the staff uses the first hydraulic rod 6 to lift the boom 2. At the same time, the drive component is used to make the two auxiliary steel cables 18 drive the auxiliary hook 19 to move upward to adjust the height of the two ends of the hose. And the second protective cover 10 contracts the main steel cable 3 to make the main hook 4 rise. In this way, the lifting of the hose can be completed. During this process, since the use distance between the two auxiliary hooks 19 can be adjusted according to the length of the hose, and at the same time, since both ends of the hose are limited to a certain extent during the lifting process, the swing of the two ends of the hose during lifting can be reduced, preventing the occurrence of axial deviation during its subsequent docking use.

[0053] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
