Description

Technical Field

[0001] This application relates to the field of hoisting and transportation technology, and in particular to a hoisting system and hoisting method. Background Technology

[0002] The transportation of heavy objects involves moving them from the ground level to the fifth basement level. The specific steps are as follows: a transport vehicle moves the heavy object to the vicinity of the installation shaft. First, the shock absorber is placed from the installation shaft into the fifth basement level. Then, a crane hook is used to lift the heavy object above the installation shaft and slowly lower it at a uniform speed, placing the object on the shock absorber frame. The connection between the crane hook and the heavy object is then removed, and bolts are used to secure the object to the shock absorber frame. Finally, the shock absorber frame is moved to transfer the heavy object to the designated location. The shock absorber frame provides protection for the heavy object, reducing the risk of damage during the transfer from the ground level to the fifth basement level and during movement within the fifth basement level.

[0003] Due to the large mass of the heavy object and the shock absorber frame, it is difficult to change the position of the shock absorber frame after it is placed on the fifth basement level. Furthermore, once the heavy object is underground, it is difficult for workers on the ground to observe its exact location, which is also inconvenient for the heavy object to be placed on top of the shock absorber frame. Therefore, a hoisting system that facilitates the hoisting of heavy objects onto the shock absorber frame is needed. Summary of the Invention

[0004] In order to facilitate the placement of heavy objects above the shock absorber frame, this application provides a hoisting system and hoisting method.

[0005] On the one hand, the hoisting system provided in this application adopts the following technical solution: A hoisting system includes a hoisting device and a guiding device. The hoisting device is used to hoist a shock absorber frame and a heavy object to the fifth basement level. The guiding device includes a lifting ring, a balance beam, and a guide cable. A guide cable support is provided on the ground, and a ground anchor is provided on the fifth basement level. The two ends of the guide cable are connected to the guide cable support and the ground anchor, respectively. The balance beam is installed on the hoisting device, and the lifting ring is used to engage the balance beam and the guide cable.

[0006] By adopting the above technical solution and setting up a guiding device, when the shock absorber frame and the heavy object are hoisted to the fifth basement level, the workers first use the hoisting device to suspend the shock absorber frame above the installation well and connect the lifting ring and the guide cable. At this time, the lifting ring, guided by the guide cable, lowers the shock absorber frame into the fifth basement level. Then, the hoisting device connects the heavy object. With the cooperation of the lifting ring and the guide cable, it is easier to place the heavy object on the shock absorber frame, reducing the situation where the workers have poor visibility on the ground and it is inconvenient to connect the heavy object to the shock absorber frame.

[0007] Optionally, a positioning device is also included, comprising a positioning frame and a movable component, a clamping component, and a correction plate mounted on the positioning frame. The movable component is used to move the position of the positioning frame, and the clamping component is used to clamp the shock absorber frame / weight. Two sets of correction plates are provided, and the two sets of correction plates are slidably mounted on the positioning frame via a drive component. A half-hole is opened on one side of the two sets of correction plates that are close to each other, and the lifting rope of the hoisting device passes through the half-hole of the two correction plates. The lifting rope is provided with a first magnetic element, and a second magnetic element is provided on the inner wall of the half-hole, and the first magnetic element and the second magnetic element cooperate with each other.

[0008] By adopting the above technical solution, a positioning device is set up to move the positioning frame so that the shock absorber / weight enters the positioning frame and is clamped by the clamping assembly. By setting up a movable component, the positioning frame can move the weight / shock absorber above the installation well. Then, the hoisting rope of the hoisting device is lowered. After the hoisting beam enters the positioning frame, the two correction plates are brought closer together by the drive assembly. Since the hoisting rope is equipped with a first magnetic component, the cooperation of the first and second magnetic components can pass the hoisting rope through the two semi-holes. Then, the first and second magnetic components are closed. If the hoisting rope is tilted in the two semi-holes, the workers slowly adjust the hoisting device to make the hoisting rope straight, so as to facilitate the connection of the hoisting rope device and the shock absorber / weight, as well as the connection of the lifting ring and the guide cable, thereby improving work efficiency.

[0009] Optionally, the drive assembly includes a first motor, a lead screw, and a guide rod, both of which are mounted on a positioning frame; two sets of correction plates are rotatably connected to the lead screw, and two sets of correction plates are slidably connected to the guide rod; the first motor is used to drive the lead screw to rotate.

[0010] By adopting the above technical solution, starting the first motor can rotate the lead screw and move the two correction plates closer to or further apart, so as to clamp the hoisting rope between the two correction plates and adjust the position of the hoisting device.

[0011] Optionally, the movable components are provided in two sets, with the two sets of movable components respectively located on both sides of the positioning frame; the movable components include two sets of rollers and two sets of second motors, with two rotating blocks rotatably mounted on the bottom of the positioning frame, the rollers rotatably mounted on the rotating blocks, and the second motors used to drive the rollers to rotate; the positioning frame is provided with a reversing component for driving the two rotating blocks to change direction.

[0012] By adopting the above technical solution, the second motor is started, which drives the roller to rotate, thereby adjusting the position of the positioning frame to facilitate the transfer of the shock absorber / weight to the top of the installation well; and by setting a reversing component, the rotation direction of the roller can be changed, further facilitating the change of the positioning frame holding the shock absorber / weight.

[0013] Optionally, the reversing assembly includes a rotating rod, a driving component, and two bevel gears, which are respectively fixed to two rotating blocks; the rotating rod is rotatably mounted on a positioning frame, and a first gear is fixed to the rotating rod, which meshes with the bevel gears; the driving component is used to drive the rotating rod to rotate.

[0014] By adopting the above technical solution, when it is necessary to change the position of the rollers, the drive unit is activated to rotate the rotating rod. Since the first gear is fixed to the rotating rod, the meshing of the first gear and the bevel gear can make the rotating block rotate, thereby changing the rotation direction of the two rollers.

[0015] Optionally, the positioning frame includes two movable frames and a crossbar, with both ends of the crossbar connected to the two movable frames respectively, and the crossbar and the movable frames are detachably connected by bolts; the movable components, clamping components and correction plates are all mounted on the movable frames.

[0016] By adopting the above technical solution, the crossbar and the movable frame are detachably connected to facilitate the disassembly and transfer of the positioning frame; and by removing part of the crossbar, the shock absorber / heavy object can be transferred into the positioning frame so that the clamping assembly can transfer it.

[0017] Optionally, the clamping assembly is provided in two sets, with the two sets of clamping assemblies located on opposite sides of the positioning frame. The clamping assembly includes two clamping plates, a first cylinder, and a second gear. Both clamping plates are slidably mounted on the positioning frame, and both clamping plates are provided with a first rack. The second gear is rotatably mounted in the positioning frame and meshes with the two first racks. The first cylinder is mounted on the positioning frame and connected to one of the clamping plates.

[0018] By adopting the above technical solution, when the two clamping plates clamp the shock absorber / weight, the first cylinder drives one of the clamping plates to move; since the first rack connected to the clamping plate meshes with the second gear, the two clamping plates can move closer to each other and clamp the weight; and by connecting the first cylinder to one of the clamping plates, since the weight is large, the first cylinder is connected to the clamping plate below the weight to reduce the possibility of the weight falling between the clamping plates.

[0019] On the other hand, this application discloses a hoisting method.

[0020] A hoisting method, comprising the following steps: S1, preparation before hoisting, installing the guide cable bracket and the ground anchor on the ground and the fifth basement level respectively, and connecting the two ends of the guide cable to the ground anchor and the guide cable respectively; S2, temporarily place heavy objects. A temporary support is set up on the ground. Use the hoisting device to transfer the heavy objects on the air cushion vehicle to the temporary support. S3, the shock absorber frame is lowered into the installation well; S4, lowering heavy objects into the installation well; S5, assemble the shock absorber frame and weights.

[0021] By adopting the above technical solution, when the shock absorber frame and the heavy object are hoisted to the fifth basement level, the shock absorber frame and the heavy object are first dismantled and transported to the ground. The workers first use the hoisting device to suspend the shock absorber frame above the installation well and connect the lifting ring and the guide cable. At this time, the lifting ring, guided by the guide cable, lowers the shock absorber frame into the fifth basement level. Then, the hoisting device connects the heavy object. With the cooperation of the lifting ring and the guide cable, it is easy to place the heavy object on the shock absorber frame, reducing the situation where the workers have poor visibility on the ground and it is inconvenient to connect the heavy object to the shock absorber frame.

[0022] Optionally, in step S2, when the heavy object is suspended in the air, the heavy object is equipped with a guide rope.

[0023] By adopting the above technical solution, and by setting up guide ropes, when the hoisting device gradually lowers the heavy object, the workers pull the guide ropes to reduce the swaying of the heavy object, so as to facilitate the lowering of the heavy object.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a guiding device, both the shock absorber frame and the heavy object are guided by guide steel cables into the fifth basement level, so as to facilitate the placement of the heavy object on the shock absorber frame and reduce the situation where the staff have poor visibility on the ground and it is inconvenient to connect the heavy object to the shock absorber frame; 2. By setting up a positioning device, the positioning frame is moved so that the shock absorber / weight enters the positioning frame, and the clamping assembly is used to clamp it, so as to facilitate the transfer of the weight to the top of the installation well and the adjustment of the position; and the balance beam, under the correction of the two correction plates, can be set so that the balance beam and the weight are aligned, thereby completing the connection between the balance beam and the weight and the connection between the balance beam and the guide cable, improving work efficiency.

[0027] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0028] This application discloses a hoisting system.

[0029] Reference Figure 1 A hoisting system includes a hoisting device 1, a guiding device 2, and a positioning device 3. The hoisting device 1 is used to hoist a shock absorber and a heavy object from the ground to the fifth basement level. The guiding device 2 is used to guide the movement of the hoisting device 1. The positioning device 3 is used to connect the hoisting device 1 and the shock absorber / heavy object.

[0030] The lifting device 1 includes a crane and a lifting rope 11. The lifting rope 11 is connected to the crane and is equipped with a crane hook 12. The crane has a specification of 10t, which is able to lift and transfer the shock absorber frame / heavy object.

[0031] The guiding device 2 includes a lifting ring 21, a balance beam 22, and a guide cable 23. The balance beam 22 is fixed with a lifting lug 25, which is connected to the crane hook 12 via a double-limb chain 24. The lifting lug 25 is also equipped with a hand chain hoist 26, which is used to connect to the shock absorber / weight. There are two sets of lifting rings 21, which are fixed to both ends of the lifting beam.

[0032] A guide cable support 27 is installed on the ground, and the column base of the guide cable support 27 is fixed to the ground by expansion bolts; a ground anchor 28 is installed on the fifth basement level, and the two ends of the guide cable 23 are connected to the guide cable support 27 and the ground anchor 28 respectively; in this embodiment, the guide cable 23 is pre-tightened by a hand-operated hoist 26 so that the guide cable 23 is in a taut state; so that when the guide device 2 lowers the heavy object / shock absorber to the ground, the hook is hooked on the guide cable 23, and the guide beam moves under the guidance of the guide cable 23, so that the movement path of the heavy object in the installation well and the movement path of the shock absorber in the installation well are the same.

[0033] Reference Figure 2 The positioning device 3 includes a positioning frame 4 and a movable component 5, a clamping component 6, and a correction plate 7 installed on the positioning frame 4. The positioning frame 4 includes a movable frame 41 and a crossbar 42. The movable frame 41 has a right-angled trapezoidal cross section. The two ends of the crossbar 42 are respectively connected to two movable frames 41. The movable frame 41 has an installation groove, and the crossbar 42 is inserted into the installation groove. The movable frame 41 has a first threaded groove, and the crossbar 42 has a second threaded groove. When the end of the crossbar 42 is inserted into the installation groove, a first bolt 43 is inserted into both the first and second installation grooves.

[0034] Reference Figure 2 and Figure 3 Two correction plates 7 are provided, each mounted on the top of a movable frame 41. The movable frame 41 is provided with a drive assembly 72 for bringing the two correction plates 7 closer together. A semi-hole 71 is provided on the side of the two correction plates 7 that is close to each other. In this embodiment, a second magnet is provided on the inner wall of the semi-hole 71, and a first magnet is provided on the suspension rope 11.

[0035] As the two correction plates 7 approach each other, the first and second magnetic components attract each other. Since the balance beam 22 is not connected to the weight / shock absorber, it is relatively light. Therefore, the suspension rope 11 enters the inner wall of the half-hole 71 under the attraction of the second magnetic component, thus clamping the suspension rope 11 between the two half-holes 71. At this time, the first and second magnetic components are closed. If the suspension rope 11 is tilted inside the correction plate 7, the staff slowly adjusts the position of the suspension rope 11 so that the suspension rope 11 is straight. This completes the correction of the position of the balance beam 22.

[0036] Reference Figure 3 and Figure 4 The drive assembly 72 includes a first motor 73, a lead screw 74, and a guide rod 75. The lead screw 74 includes a first drive rod 741 and two second drive rods 742, which are rotatably mounted on the upper surfaces of two movable frames 41 respectively. The first drive rod 741 is rotatably mounted on one of the crossbars 42. In this embodiment, both ends of the first drive rod 741 are equipped with first insertion blocks 743, and the second drive rods 742 have first insertion slots 744 for the first insertion blocks 743 to be inserted into. The first motor 73 is fixedly connected to one of the movable rods and the second drive rods 742. By driving the first motor 73, the first drive rod 741 and the two second drive rods 742 can be rotated.

[0037] Reference Figure 3 The guide rod 75 includes a first fixed rod 751 and two second fixed rods 752. The two second fixed rods 752 are respectively fixed to the upper surface of the movable frame 41. The first fixed rod 751 is fixed to one of the crossbars 42. When the crossbar 42 is connected to the two movable frames 41, the first fixed rod 751 and the two second fixed rods 752 are positioned opposite each other. One end of each of the two correction plates 7 is rotatably connected to the two second rotating rods 541; the other end of each of the two correction plates 7 is slidably connected to the two second fixed rods 752. Starting the first motor 73 can rotate the lead screw 74 and move the two correction plates 7 closer to or further away from each other, so that the lifting rope 11 can be clamped between the two correction plates 7 to adjust the position of the lifting device 1.

[0038] Reference Figure 5 and Figure 6 Two sets of clamping components 6 are provided, each set positioned on one side of the two movable frames 41 that are close to each other. Each clamping component 6 includes two clamping plates 61, a first cylinder 62, and a second gear 63. The movable frame 41 has two sliding grooves 44, spaced apart along the height of the movable frame 41, with the extension direction of the sliding grooves 44 being the same as the extension direction of the movable frame 41. The two clamping plates 61 are slidably installed within the two sliding grooves 44. A first rack 64 is fixed to each of the two clamping plates 61. The movable frame 41 has a rotating groove 45 communicating with the two sliding grooves 44. The second gear 63 is rotatably installed within the rotating groove 45, and both first racks 64 mesh with the second gear 63. The first cylinder 62 is installed on the movable frame 41, and the movable piston of the first cylinder 62 is fixed to the clamping plate 61 located below.

[0039] When the two clamping plates 61 clamp the shock absorber / weight, the first cylinder 62 drives one of the clamping plates 61 to move. Since the first rack 64 connected to the two clamping plates 61 meshes with the second gear 63, the two clamping plates 61 can be brought closer to each other and clamp the weight. By connecting the first cylinder 62 to one of the clamping plates 61, and since the weight is large, the first cylinder 62 will be connected to the clamping plate 61 below the weight to reduce the possibility of the weight falling between the clamping plates 61.

[0040] Reference Figure 7 and Figure 8 The movable component 5 is provided in two sets, and the two sets of movable components 5 are respectively set at the bottom of the two movable frames 41. The movable component 5 includes two sets of rollers 51 and two sets of second motors 52. A rotating block 53 is rotatably mounted at the bottom of the movable frame 41, and the rollers 51 are rotatably mounted on the rotating block 53. The two sets of second motors 52 are respectively fixed to the two rotating blocks 53, and the output shaft of the second motor 52 is connected to the rollers 51.

[0041] Reference Figure 9 The positioning frame 4 is equipped with a reversing assembly 54, which includes a rotating rod 541, a driving component 543, and two bevel gears 542. The movable frame 41 has a reversing cavity 46. The two bevel gears 542 are rotatably installed in the reversing cavity 46 and are respectively fixed to two rotating blocks 53. The rotating rod 541 is rotatably installed in the reversing cavity 46. The rotating rod 541 is fixed with two first gears 55, which mesh with the two bevel gears 542 respectively. The positioning frame 4 is equipped with a driving component 543 for driving the rotating rod 541 to rotate.

[0042] The drive unit 543 includes a third gear 544, a second cylinder 546, and a third rack 545. The third gear 544 is fixed to the rotating rod 541; the second cylinder 546 is fixed to the positioning frame 4; the third gear 544 is located in the reversing cavity 46 and is fixed to the movable plug of the second cylinder 546; and the third gear 544 and the third rack 545 mesh. Activating the movable plug of the third cylinder 57 causes the third gear 544 to rotate, thereby causing the two first gears 55 to rotate under the drive of the rotating rod 541, which in turn causes the rotating block 53 to rotate and reverses the direction of the roller 51; thus changing the travel direction of the positioning frame 4 holding the shock absorber / weight.

[0043] Reference Figure 8 In this embodiment, the positioning frame 4 is equipped with a third cylinder 57, and the movable plug of the third cylinder 57 faces the top of the positioning frame 4. When the roller 51 is turned, the movable plug of the third cylinder 57 is brought into contact with the ground, so that there is a gap between the roller 51 and the ground, which further improves the convenience of rotating the roller 51.

[0044] The implementation principle of Embodiment 1 of this application is as follows: When the shock absorber frame and the heavy object are both hoisted to the fifth basement level, the workers first use the hoisting device 1 to suspend the shock absorber frame above the installation well and connect the lifting ring 21 and the guide cable 23. At this time, the lifting ring 21, guided by the guide cable 23, lowers the shock absorber frame into the fifth basement level. Then, the hoisting device 1 connects the heavy object. With the cooperation of the lifting ring 21 and the guide cable 23, it is easier to place the heavy object on the shock absorber frame, reducing the situation where the workers have poor visibility on the ground and it is inconvenient to connect the heavy object to the shock absorber frame.

[0045] This application also discloses a hoisting method, which includes the following steps: Before hoisting S1, the guide cable and ground anchor 28 are installed on the ground and the fifth basement level, respectively. The guide cable and ground anchor 28 are connected by the guide steel cable 23, and the guide cable is pre-tightened by a manual hoist.

[0046] S2 temporarily places the heavy object. After the air mattress transports the heavy object and shock absorber frame to the installation site, the hoisting device 1 places the heavy object and shock absorber on the ground. A temporary support is erected on the ground to place the heavy object on top of the temporary support, reducing the risk of damage from contact between the heavy object and the ground support. Furthermore, during the placement of the heavy object on the temporary support, a guide rope is installed. By pulling the guide rope, the possibility of the heavy object swaying freely in the air is reduced, improving the stability of the heavy object installed on the temporary support.

[0047] S3. Lower the shock absorber frame into the installation well. Remove the two horizontal bars 42 on the upper and lower parts of the positioning frame 4, allowing the shock absorber frame to enter the positioning frame 4. Then, use the clamping assembly 6 to clamp and fix the shock absorber frame. Reconnect the two movable frames 41 using the horizontal bars 42. Start the second motor 52 to rotate the roller 51, and adjust the direction of travel of the roller 51 through the reversing assembly 54 so that the shock absorber frame is positioned between the two guide cables 23. Start the crane to move the balance beam 22 between the two movable frames 41. Activate drive assembly 72, bring the correction plates 7 close together, and with the cooperation of the first and second magnetic components, allow the hoisting rope 11 to enter the semi-holes 71 of the two correction plates 7; close the first and second magnetic components, and slowly adjust the crane to keep the hoisting rope 11 straight. This facilitates the connection of the balance beam 22 and the shock absorber frame; then remove the positioning frame 4, and slowly lower the shock absorber frame to complete the connection of the hook and guide cable 23; the shock absorber frame enters the fifth basement level under the guidance of the guide cable 23.

[0048] S4 lowers the heavy object into the installation well. Use positioning frame 4 to transfer the heavy object to the top of the installation well. Connect the heavy object to the lifting beam and the heavy object. Then connect the balance beam 22 and the guide cable 23. The heavy object enters the top of the shock absorber under the guidance of the guide cable 23.

[0049] S5 assembles the shock absorber frame and the weight, removes the balance beam 22 and the weight, connects the weight and the shock absorber frame, and then moves the balance beam 22 and the weight to the installation location at the same time.

[0050] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
