[0012] This invention provides a large-scale pipe hoisting device for underground parking garages, which has the following advantages:

[0013] 1. The large-scale pipe hoisting device in the underground parking garage of this building, equipped with studs, fixing frames, and fasteners, can automatically hoist ventilation ducts without requiring multiple workers to lift them. This reduces the need for manpower and allows for fewer personnel to be assigned to the pipe hoisting work. While hoisting the ventilation ducts, the device can drive the nut to rotate and move along the outside of the stud, limiting the position of the fasteners and the ventilation ducts above. No subsequent adjustment of the nut height is required; the fixing nut can be directly screwed onto the outside of the stud and the bottom of the fastener to fix the position of the fasteners and the ventilation ducts.

[0014] 2. The large pipe hoisting device in the underground garage of this building is equipped with a fixed half-ring, a drive box, and a fixing frame. After hoisting the ventilation duct, the second self-locking hook is removed from the hook ring. Then, the operator rotates the worm gear, which drives the take-up roller to rotate through the worm wheel, allowing the traction rope to be released from the outside of the take-up roller. The hook ring is then hooked onto the first self-locking hook. The operator then resets and rotates the screw, which pushes one end of the insert into the slot to fix the position of the half-tooth ring. The bolt fixing assembly is then unlocked, and the other fixed half-ring is removed from the outside of the stud. The first bolt is then unscrewed from the outside of the first screw, and the first screw is removed from the inside of the two first and second mounting blocks. The drive box, top plate, and guide wheel mechanism are then removed for reuse. The traction rope, take-up box and take-up roller, hook ring and fixing rope, lifting ring, and first self-locking hook further limit and fix the position of the fixing parts and ventilation duct to prevent the ventilation duct and fixing parts from falling when the fixing bolts loosen.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Example 1

[0029] Please see Figures 1 to 11This invention provides a technical solution: a large-scale pipe hoisting device for an underground parking garage, comprising an underground parking garage structure 1 and a ventilation duct 59. Several studs 2 are fixedly connected to the top of the inner cavity of the underground parking garage structure 1. A fixing frame 3 is fitted around the outside of each stud 2. A drive box 9 is placed on one side of the fixing frame 3, and a first self-locking hook 35 is placed on the other side of the fixing frame 3. Several top plates 10 are fixedly connected to the top of the drive box 9. Several moving carts 60 are arranged at the bottom of the inner cavity of the underground parking garage structure 1. A winding mechanism 31 is fixedly connected to the top of each moving cart 60. A hoisting rope 12 is installed inside each winding mechanism 31. One end of each hoisting rope 12 passes through three guide wheel mechanisms 11 and extends to below the top plate 10, where a second self-locking hook 47 is fixedly connected. Each second self-locking hook 47 is hooked with a... A hook 46 is fixedly connected to one end of each hook 46 with a traction rope 42. A fixed seat 50 is fixedly connected to both sides of the ventilation duct 59. A lifting ring 49 is fixedly connected to the top of each fixed seat 50. A fixed rope 48 is wound around each lifting ring 49. A winding box 40 is fixedly connected to one end of each fixed rope 48. A winding roller 41 is rotatably connected inside the winding box 40. The traction rope 42 is wound around the outside of the winding roller 41. A transmission box 43 is fixedly connected to one side of the winding box 40. One end of each winding roller 41 extends into the transmission box 43 and is rotatably connected to one side of the inner cavity of the transmission box 43. A worm gear 45 is fixedly sleeved on the outside of each winding roller 41. A worm 44 is rotatably connected inside the transmission box 43 and is driven by the worm gear 45. The top of each worm 44 extends to the top of the transmission box 43.

[0030] Among them, a fixing member 38 is placed below the ventilation duct 59. Several positioning blocks 51 are fixedly connected to the top of the fixing member 38. The bottom of the fixing seat 50 is provided with a positioning groove 52. The positioning blocks 51 are inserted into the positioning groove 52. The fixing seat 50 is provided with a moving groove 53 on both sides of the positioning groove 52. A fixing spring 58 is fixedly connected to one side of the inner cavity of the moving groove 53. A locking block 54 is fixedly connected to one end of the fixing spring 58. One end of the locking block 54 is inserted into the positioning block 51. The positioning block 51 and the fixing member 38 are fixed by the locking block 54.

[0031] The fixed base 50 has a drive groove 55 located inside and above the moving groove 53. A bidirectional ball screw 56 is rotatably connected to the inner cavity of the drive groove 55. Drive blocks 57 are threaded to the opposite positions of the outer threads of the bidirectional ball screw 56. The other end of the locking block 54 extends into the drive groove 55. The drive blocks 57 are located on one side of one end of the locking block 54. One end of the bidirectional ball screw 56 extends to the outside of the fixed base 50. When it is necessary to remove the fixing part 38, the operator rotates the bidirectional ball screw 56, causing the bidirectional ball screw 56 to drive the drive block 57 to move. The drive block 57 pushes one end of the locking block 54 out of the positioning block 51, so that the positioning block 51 can be removed from the positioning groove 52. Then the fixing part 38 is removed from the bottom of the ventilation duct 59. Then the operator rotates the bidirectional ball screw 56 to reset and drive the drive block 57 to move back. At this time, the fixed spring 58 can push the locking block 54 to move back.

[0032] The drive box 9 has a sliding block 15 slidably connected to its inner cavity. A rotating rod 14 is rotatably connected to the bottom of each inner cavity. The top of each rotating rod 14 passes through the moving block 15 and extends above it. A servo motor 13 is fixedly connected to the top of each inner cavity. The output end of each servo motor 13 is fixedly connected to the top of each rotating rod 14. A first pulley 16 is movably sleeved on the outer side of each rotating rod 14. A spline groove 17 is formed on the outer side of each rotating rod 14. A spline component 18 is provided inside each spline groove 17. One end of each spline component 18 is connected to the inner side of the first pulley 16. A fixed block 19 is fixedly connected to the top of each moving block 15. A ring is formed inside each fixed block 19. The groove 20 and the annular groove 20 are both slidably connected to the limiting rod 21. The top of the limiting rod 21 extends above the fixed block 19 and is fixedly connected to the bottom of the first pulley 16. When the nut 28 rotates and moves along the outside of the stud 2, the nut 28 drives the half gear ring 26, the fixed half ring 25 and the moving block 15 to move through the insert block 27. The moving block 15 drives the fixed block 19 to move along the outside of the rotating rod 14. The fixed block 19 drives the first pulley 16 to move along the outside of the rotating rod 14 through the annular groove 20 and the limiting rod 21. The first pulley 16 is always connected to the spline groove 17 and the rotating rod 14 through the spline member 18.

[0033] Each movable block 15 has a drive cavity 22 inside, and a rotating shaft 23 is rotatably connected inside each drive cavity 22. A second pulley 24, which is connected to the first pulley 16 via belt drive, is fixedly sleeved on the outside of each rotating shaft 23. A transmission gear 39 is fixedly sleeved on the outside of each rotating shaft 23. One end of the movable block 15 extends to the outside of the drive box 9 and is provided with two fixed half rings 25. The outside of one fixed half ring 25 is fixedly connected to one end of the movable block 15. The two fixed half rings 25 are fixedly connected by a bolt fixing assembly 37. A half gear ring 26 is slidably connected inside each fixed half ring 25. Both ends of one half gear ring 26 are inserted into the two ends of the other half gear ring 26. The two half gear rings 26 form a transmission gear ring, and the transmission gear ring cooperates with the transmission gear 39, which makes it convenient to remove the drive box 9 from one side of the stud 2 for reuse.

[0034] Each of the fixed half-rings 25 has a threaded block 29 fixedly connected to its top. Each threaded block 29 has a screw 30 threadedly connected inside. One end of the screw 30 is rotatably connected to a post 32. Each of the half-gear rings 26 has several slots 33 that mate with the posts 32. The slots 33 and posts 32 can limit and fix the position of the half-gear rings 26, preventing them from detaching from the fixed half-rings 25 during disassembly and installation, thus affecting the use of the device.

[0035] The stud 2 has a fixing groove 36 on both sides, and the fixing bracket 3 has a first quick-tight screw 34 threaded on both sides. One end of the first quick-tight screw 34 is inserted into the fixing groove 36, and the other end of the first quick-tight screw 34 extends to the outside of the fixing bracket 3 so that the device can be installed on the outside of the stud 2 for use.

[0036] Example 2

[0037] Please see Figure 1 , Figure 4 and Figure 9 The present invention provides a technical solution: two first mounting blocks 4 are fixedly connected to one end of the fixing frame 3, and a second mounting block 6 is fixedly connected to one side of the drive box 9. The second mounting blocks 6 are located between the two first mounting blocks 4. A first screw 7 is inserted inside the second mounting block 6. One end of the first screw 7 extends to one side of one first mounting block 4, and the other end of the first screw 7 extends to one side of the other first mounting block 4. A first bolt 8 is threaded to the outer side of the tail end of the first screw 7, which can install the drive box 9, the top plate 10 and the guide wheel mechanism 11 together with the fixing frame 3.

[0038] In summary, the large pipe hoisting device in the underground garage of this building is used by fixing stud 2 to the top of the inner cavity of the underground garage 1, then placing the fixing frame 3 on the outside of stud 2, and then the operator screws one end of the first quick-release screw 34 into the fixing groove 36 to fix the position of the fixing frame 3. Then, the drive box 9 is placed on one side of the fixing frame 3, so that the second mounting block 6 is located between the two first mounting blocks 4. Then, the operator passes the first screw 7 through one first mounting block 4, the second mounting block 6, and the other first mounting block 4, and the tail end of the first screw 7 protrudes to one side of one first mounting block 4. Then, the first bolt 8 is screwed on the outside of the tail end of the first screw 7 to fix the position of the drive box 9 and the fixing frame 3. When using the device, the operator places the nut 28 inside one of the fixed half-rings 25, then places the other fixed half-ring 25 on one side of the first fixed half-ring 25. The two fixed half-rings 25 are then secured using the bolt fixing assembly 37. The operator then turns the screw 30, causing it to move one end of the insert 32 out of the slot 33. The fixing rope 48 is then passed through the lifting ring 49 and wound around it. At this time, the winding mechanism 31 winds up the lifting rope 12, causing the lifting rope 12 to move the second self-locking hook 47, hook ring 46, traction rope 42, winding box 40, fixing rope 48, lifting ring 49, fixing seat 50, and ventilation duct 59 upwards. When the ventilation duct 59 has moved upwards a certain distance, the fixing member 38 is released. The device is placed below the ventilation duct 59. Then, the fixing member 38 is pushed, which pushes the positioning block 51 into the positioning groove 52, so that the arc surface at the end of the positioning block 51 contacts the arc surface at one end of the locking block 54, causing the locking block 54 to move into the moving groove 53. When the fixing holes on both sides of the positioning block 51 are at one end of the locking block 54, the fixing spring 58 pushes one end of the locking block 54 into the fixing hole, fixing the position of the positioning block 51 and the fixing member 38. Then, the ventilation duct 59 continues to move upward, so that the bottom of the fixing member 38 contacts the bottom end of the nut 28. At this time, the output end of the servo motor 13 drives the rotating rod 14 to rotate, so that the rotating rod 14 drives the first pulley 16 to rotate through the spline groove 17 and the spline member 18. This causes the first pulley 16 to drive the limiting rod 21 to move along the inside of the annular groove 20, causing the first pulley 16 to drive the second pulley 24 to rotate via the belt, causing the second pulley 24 to drive the rotating shaft 23 to rotate, causing the rotating shaft 23 to drive the transmission gear 39 to drive the transmission gear ring to move, causing the half gear ring 26 to drive the insert block 27 to rotate, causing the insert block 27 to drive the nut 28 to move circumferentially, causing the nut 28 to rotate around the outside of the stud 2, causing the nut 28 to rotate and move on the outside of the stud 2. At the same time, the stud 2 passes through the through hole opened on the fixing member 38 and extends to the bottom of the fixing member 38 to hoist the ventilation duct 59. When the ventilation duct 59 is hoisted to the designated height, the fixing nut is screwed on the outside of the stud 2.The fixing nuts 28 and 28 are used to secure the positions of the fixing member 38 and the ventilation duct 59. Then, the second self-locking hook 47 is removed from the hook ring 46. The operator then rotates the worm gear 44, causing it to drive the take-up roller 41 through the worm wheel 45, releasing the traction rope 42 from the outside of the take-up roller 41. The hook ring 46 is then hooked onto the first self-locking hook 35. The operator then resets and rotates the screw 30, causing it to push one end of the insert 32 into the slot 33, fixing the position of the half-tooth ring 26. The bolt fixing assembly 37 is then unlocked, and the other fixing half-ring 25 is removed from the outside of the stud 2. The first bolt 8 is then unscrewed from the outside of the first screw 7, and the first screw 7 is removed from inside the two first mounting blocks 4 and the second mounting block 6. Finally, the drive box 9, top plate 10, and guide wheel mechanism 11 are removed for reuse.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
