Description

Technical Field

[0001] The present invention belongs to the technical field of wind power generation equipment, and relates to a hoisting tooling, in particular to a hoisting tooling for vertical tower barrel accessories. Background Art

[0002] With the reduction of global oil and coal resources, the development of renewable energy is imperative. After years of research and practice, the related technologies of renewable energy such as wind energy, water energy, and solar energy have gradually matured and been widely applied.

[0003] As one of the renewable energies, wind energy is given priority to, and the global wind power industry shows a trend of large-scale and rapid development, which means that the installed capacity of wind turbines continues to increase.

[0004] Currently, during the installation process of the tower barrel, it is necessary to hoist the components of the tower barrel and then carry out subsequent installation.

[0005] Since there are equipment installed inside the tower barrel and the center of the tower barrel is not in its axial direction, during the hoisting process, due to the offset of the center of gravity of the tower barrel, the hoisting frame will tilt, resulting in hoisting hidden dangers.

[0006] Therefore, during the hoisting process, how to balance and adjust the hoisting equipment and how to ensure the safety of hoisting construction are problems that need to be solved. Summary of the Invention

[0007] The purpose of the present invention is to address the above problems existing in the prior art, and propose a hoisting tooling for vertical tower barrel accessories. The technical problems to be solved by this invention are: how to achieve the balance of the hoisting equipment and the safety of hoisting construction.

[0008] The purpose of the present invention can be achieved by the following technical solutions:

[0009] A hoisting tooling for vertical tower barrel accessories, comprising a hanging plate, a first hoisting rope, a second hoisting rope, a hook, a base and a support frame assembly;

[0010] A plurality of first hanging ears are fixed at the bottom of the hanging plate. The upper ends of the first hoisting ropes are connected to the first hanging ears, and the lower ends of the first hoisting ropes are connected to the support frame assembly. A plurality of second hanging ears are fixed at the top of the hanging plate. The lower ends of the second hoisting ropes are connected to the second hanging ears, and the upper ends of the second hoisting ropes are connected to the hook;

[0011] The base is fixed on the support frame assembly. The support frame assembly includes a plurality of support pipes. An adjustment assembly is provided inside the support pipes, a power assembly for controlling the sliding of the adjustment assembly is provided on the support pipes, and a limit assembly for restricting the rotation direction of the power assembly is provided on the support pipes.

[0012] The working principle of the present invention is as follows: Place the tower barrel component on the base, lift the base and the support frame assembly upward by a certain distance, and observe whether the base is tilted; when the base is tilted, on one side of the lower end of the base, extend the arc plate outward, and the operator rotates the rotating shaft by rotating the handwheel assembly, so as to drive the arc plate to move through the driving gear. Among them, the base squeezes the support frame assembly, and the base and the cushion block squeeze the tops of multiple moving columns. The moving columns slide downward in the guide tubes, the first spring is in a compressed state, and the pressing head presses down one end of the lever component, so that the other end of the lever component drives the sliding plate to move upward; at this time, the limiting block abuts against the ratchet wheel, and the second spring is in a natural length state or a compressed state. When the ratchet wheel rotates in the predetermined direction, the circumferential surface of the ratchet wheel squeezes the second spring to rotate smoothly. When the rotation direction of the ratchet wheel is opposite to the predetermined direction, the side surface of the limiting block is stressed, which hinders the ratchet wheel to prevent the ratchet wheel from continuing to rotate. After the tower barrel component is hoisted, unload the tower barrel component and remove the base from the support frame assembly. At this time, under the action of the first spring, the moving columns move upward, and then the sliding plate moves downward, and the ratchet wheel is separated from the limiting block, thereby unlocking the limiting mechanism. At this time, the second spring is in a natural length state, and the operator can rotate the rotating shaft in the reverse direction to adjust the arc plate to retract into the support tube for the next hoisting preparation.

[0013] The suspension plate includes four load-bearing rods, and the four load-bearing rods are sequentially connected into a square frame structure. The second lifting lug is fixed at the top of the load-bearing rod, and the first lifting lug is fixed at the middle position of the bottom of the load-bearing rod.

[0014] With the above structure, the second lifting lug and the first lifting lug are respectively fixed at the top and bottom of the load-bearing rod, which is convenient for the connection and installation of the first lifting rope and the second lifting rope.

[0015] Four support tubes are arranged in a cross shape. Among them, the two support tubes located above are fixed on the tops of the two support tubes located below; a cushion block is fixed at the lower part of the base, the lower surface of the base abuts against the support tube located above, and the lower surface of the cushion block abuts against the support tube located below.

[0016] With the above structure, the four support tubes are arranged in a cross shape to completely cover the bottom of the support frame assembly, so that the overall force on the support frame assembly is uniform, and thus the force on each first lifting rope is also more uniform. Moreover, the two ends of the multiple support tubes do not interfere with each other, which is convenient for the normal operation of the adjustment assembly, and also convenient for the installation and use of the power assembly and the handwheel assembly, improving the use comfort of the equipment. The lower surface of the base abuts against the support tube located above, and the lower surface of the cushion block abuts against the support tube located below, thereby realizing the control of the limiting assembly.

[0017] The adjustment assembly is arranged inside the support tube, and one is provided at each end of the support tube;

[0018] The adjusting component includes an arc-shaped plate, a support base, a support roller, a vertical plate and a lifting ring;

[0019] The support base is fixed at the bottom of the support pipe, the vertical plates are vertically fixed on both sides of the support base, both ends of the support roller are rotatably arranged on the vertical plates, a plurality of support rollers are arranged along the arc direction, the arc-shaped plate is slidably arranged inside the support pipe, both sides of the arc-shaped plate abut against the vertical plates, and the arc-shaped plate and the power component form a transmission pair;

[0020] One end of the arc-shaped plate is slidably inserted into the support pipe, and the bottom of the arc-shaped plate presses against the circumferences of a plurality of support rollers;

[0021] The other end of the arc-shaped plate extends out of the support pipe, and this end is fixedly connected to the lifting ring;

[0022] Wherein, the lifting rings located at both ends of one support pipe are respectively connected to the same first lifting ear through two first lifting ropes, and this first lifting ear is located directly above this support pipe.

[0023] With the above structure, when the base is tilted, on one side of the lower end of the base, the arc-shaped plate is extended outwards, and the corresponding first lifting rope adjusts the force direction of this support pipe, so as to adjust the tilt angle of the base and the support frame assembly, and reduce the tilt angle of the base and the support frame assembly;

[0024] Since the arc-shaped plate is arc-shaped, when the arc-shaped plate extends outwards, the top of the arc-shaped plate moves upwards, and the arc-shaped plate forms a guardrail shape, which has a good protection effect and a good interception effect on the tower barrel components, thereby improving the safety of hoisting the tower barrel components.

[0025] The bottom of the arc-shaped plate and the circumferences of the support rollers form rolling friction to ensure the smooth movement of the arc-shaped plate; both sides of the arc-shaped plate abut against the vertical plates, and the vertical plates limit the arc-shaped plate to prevent the arc-shaped plate from swaying laterally during the movement process.

[0026] The lifting rings located at both ends of one support pipe are respectively connected to the same first lifting ear through two first lifting ropes, and this first lifting ear is located directly above this support pipe, so as to ensure that the force conditions at both ends of each support pipe only correspond to one first lifting ear, and the force conditions between multiple support pipes do not interfere with each other, thereby facilitating the adjustment of the two adjusting components inside a single support pipe.

[0027] The power component includes a rotating shaft, a driving gear, a ratchet wheel and a transmission wheel;

[0028] A first through hole for the rotating shaft to pass through is opened on the side wall of the support pipe, a bearing seat for installing the rotating shaft is arranged on the inner circumference of the first through hole, and a rack is fixed on the inner circumferential surface of the arc-shaped plate;

[0029] One end of the rotating shaft extends into the interior of the support tube and is rotatably connected to the inner wall of the support tube, and the other end of the rotating shaft is located outside the support tube;

[0030] The driving gear is key-connected to the rotating shaft. The driving gear is located inside the support tube and meshes with the arc plate;

[0031] The transmission wheel is key-connected to the rotating shaft. The transmission wheel is located outside the support tube, and the transmission wheel and the handwheel assembly form a transmission pair;

[0032] The ratchet wheel is key-connected to the rotating shaft. The ratchet wheel is located inside the support tube, and the limiting component cooperates with the ratchet wheel to form a limiting mechanism.

[0033] With the above structure, the operator rotates the rotating shaft by rotating the handwheel assembly, thereby driving the arc plate to move through the driving gear. The driving gear presses the arc plate to limit the arc plate to prevent the arc plate from shaking longitudinally and improve the stability of the movement of the arc plate; A bearing seat for installing the rotating shaft is provided on the inner circumference of the first through hole, and the bearing seat has a good supporting effect to ensure the best stability of the rotation of the rotating shaft; the ratchet wheel is key-connected to the rotating shaft, and the limiting component cooperates with the ratchet wheel to form a limiting mechanism to ensure that the rotating shaft can only rotate in one direction, that is, the arc plate can only extend outwards from the support tube and cannot retract into the support tube, thereby ensuring the limitation of the position of the arc plate and avoiding the deformation of the arc plate to improve the safety of equipment use.

[0034] The limiting component includes a moving column, a first spring, a lever component, a fixing plate, a sliding plate, a second spring and a limiting block;

[0035] A second through hole is opened at the top of the support tube, a guide tube is fixed at the position of the second through hole, the guide tube is located inside the support tube, the moving column is slidably arranged in the guide tube, the first spring is fixed at the bottom of the support tube, and the top of the first spring is connected to the bottom of the moving column. A pressing head is fixed in the middle of the moving column;

[0036] The fixing plate is fixed inside the support tube, the sliding plate is slidably arranged on the fixing plate in the vertical direction, the lower end of the second spring is fixed on the sliding plate, the upper end of the second spring is connected to the limiting block, and the limiting block is located directly below the large wheel;

[0037] The lever component is fixed inside the support tube, one end of the lever component is located below the pressing head, and the other end of the lever component is located below the sliding plate;

[0038] The bottom of the base and the cushion block presses the top of the corresponding support tube.

[0039] With the above structure, when the tower barrel component is placed on the base, the base squeezes the support frame assembly, and the base and the cushion block squeeze the tops of multiple moving columns. The moving columns slide downward in the guide tubes, the first spring is in a compressed state, and the pressing head presses one end of the lever component downward, so that the other end of the lever component drives the sliding plate to move upward; at this time, the limit block abuts against the ratchet wheel, and the second spring is in a natural length state or a compressed state.

[0040] When the ratchet wheel rotates in the predetermined direction, the circumferential surface of the ratchet wheel squeezes the second spring to rotate smoothly.

[0041] When the rotation direction of the ratchet wheel is opposite to the predetermined direction, the side of the limit block is stressed, which hinders the ratchet wheel to prevent it from continuing to rotate.

[0042] After the hoisting of the tower barrel component is completed, unload the tower barrel component and remove the base from the support frame assembly. At this time, under the action of the first spring, the moving columns move upward, and then the sliding plate moves downward, and the ratchet wheel disengages from the limit block, thereby unlocking the limit mechanism. At this time, the second spring is in a natural length state, and the operator can reverse the rotation of the rotating shaft to retract the arc-shaped plate into the support tube for the next hoisting preparation.

[0043] The limit block is columnar, and a guide sleeve for guiding the limit block is provided at the top of the fixed plate.

[0044] With the above structure, the guide sleeve ensures that the limit block moves in the predetermined direction. At the same time, the guide sleeve can support the limit block, improving the limit effect of the limit block on the ratchet wheel.

[0045] An elastic pad is fixed on the lower surface of the base, and an elastic pad is fixed on the lower surface of the cushion block.

[0046] With the above structure, the elastic pad has a good buffering effect and has a good protective effect on the support tube and the limit block.

[0047] An elastic pad is fixed between the bottom of the support seat and the support tube.

[0048] With the above structure, the elastic pad has a good buffering effect and has a good protective effect on the support seat.

[0049] Both ends of the first lifting rope and the second lifting rope are connected with hooks.

[0050] With the above structure, the hooks are convenient for quickly connecting with the lifting rings and the first lifting lugs, improving the work efficiency.

[0051] Compared with the prior art, the vertical tower barrel accessory hoisting tooling has the following advantages:

[0052] 1. Place the tower barrel component on the base, lift the base and the support frame assembly upward for a certain distance, and observe whether the base is tilted. If the base remains horizontal, it indicates that the center of gravity of the tower barrel component is located at its central position, and then the hoisting can be continued. If the base is tilted, it means that the center of gravity of the tower barrel component has shifted. At this time, adjust the adjustment component through the power component to change the force angle of the first lifting rope, so as to adjust the base and ensure that the base is in a horizontal state as much as possible, thereby improving the safety of hoisting.

[0053] 2. In the present invention, the adjustment component is adjusted through the power component to change the force angle of the first lifting rope, so as to adjust the base and ensure that the base is in a horizontal state as much as possible, thereby improving the safety of hoisting.

[0054] 3. In the present invention, the four support pipes are arranged in a cross shape to completely cover the bottom of the support frame assembly, so that the overall force on the support frame assembly is uniform, and further the force on each first lifting rope is more uniform. Moreover, the two ends of the multiple support pipes do not interfere with each other, which is convenient for the normal operation of the adjustment component and also convenient for the installation and use of the power component and the handwheel component, improving the comfort of equipment use. The lower surface of the base abuts against the support pipe located above, and the lower surface of the cushion block abuts against the support pipe located below, thereby realizing the control of the limit component.

[0055] 4. In the present invention, the arc-shaped plate is extended outwards, and the corresponding first lifting rope adjusts the force direction of the support pipe, so as to adjust the tilt angle of the base and the support frame assembly, reducing the tilt angle of the base and the support frame assembly. At the same time, the arc-shaped plate is arc-shaped. When the arc-shaped plate extends outwards, the top of the arc-shaped plate moves upwards, and the arc-shaped plate forms a guardrail shape, which has a good protective effect and a good interception effect on the tower barrel component, thereby improving the safety of hoisting the tower barrel component.

[0056] 5. In the present invention, both sides of the arc-shaped plate abut against the vertical plate, and the vertical plate limits the arc-shaped plate to prevent the arc-shaped plate from shaking horizontally during the movement. The driving gear presses the arc-shaped plate to limit the arc-shaped plate to prevent the arc-shaped plate from shaking longitudinally. The sling rings at both ends of a support pipe are respectively connected to the same first lifting ear through two first lifting ropes, and the first lifting ear is located directly above the support pipe to ensure that the force conditions at both ends of each support pipe only correspond to one first lifting ear, and the force conditions between multiple support pipes do not interfere with each other, which is convenient for adjusting the two adjustment components inside a single support pipe.

[0057] 6. In the present invention, the ratchet key is connected to the rotating shaft, and the limit component cooperates with the ratchet to form a limit mechanism to ensure that the rotating shaft can only rotate in one direction, that is, the arc-shaped plate can only extend outwards from the support pipe and cannot retract into the support pipe, thereby ensuring the limitation of the position of the arc-shaped plate and avoiding the deformation of the arc-shaped plate, so as to improve the safety of equipment use.

Detailed Description of the Invention

[0066] The following are specific embodiments of the present invention in combination with the drawings, further describing the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0067] As Figures 1-7 shown, this embodiment provides a lifting tool for vertical tower barrel accessories, including a hanging plate 1, a first lifting rope 13, a second lifting rope 14, a hook 15, a base 2 and a support frame assembly 3;

[0068] A plurality of first lifting lugs 11 are fixed at the bottom of the hanging plate 1, the upper end of the first lifting rope 13 is connected to the first lifting lug 11, the lower end of the first lifting rope 13 is connected to the support frame assembly 3, a plurality of second lifting lugs 12 are fixed at the top of the hanging plate 1, the lower end of the second lifting rope 14 is connected to the second lifting lug 12, and the upper end of the second lifting rope 14 is connected to the hook 15;

[0069] The base 2 is fixed on the support frame assembly 3. The support frame assembly 3 includes a plurality of support tubes 30. An adjustment assembly 6 is provided inside the support tube 30. A power assembly 4 for controlling the sliding of the adjustment assembly 6 is provided on the support tube 30. A limit assembly 7 for restricting the rotation direction of the power assembly 4 is provided on the support tube 30.

[0070] Place the tower barrel component on the base 2, lift the base 2 and the support frame assembly 3 upward by a certain distance, and observe whether the base 2 is tilted.

[0071] If the base 2 remains horizontal, it means that the center of gravity of the tower barrel component is at its central position, and then the hoisting can be continued; if the base 2 is tilted, it means that the center of gravity of the tower barrel component has shifted. At this time, adjust the adjustment assembly 6 through the power assembly 4 to change the force angle of the first lifting rope 13, so as to adjust the base 2 and ensure that the base 2 is in a horizontal state as much as possible, thereby improving the safety of hoisting.

[0072] The lifting plate 1 includes four load-bearing rods 10. The four load-bearing rods 10 are connected in sequence to form a square frame structure. The second lifting ear 12 is fixed at the top of the load-bearing rod 10. The first lifting ear 11 is fixed at the middle position of the bottom of the load-bearing rod 10.

[0073] The second lifting ear 12 and the first lifting ear 11 are respectively fixed at the top and bottom of the load-bearing rod 10, which is convenient for the connection and installation of the first lifting rope 13 and the second lifting rope 14.

[0074] Four support tubes 30 are arranged in a cross shape. Among them, the two support tubes 30 located above are fixed on the tops of the two support tubes 30 located below.

[0075] A cushion block 20 is fixed at the lower part of the base 2. The lower surface of the base 2 abuts against the support tube 30 located above. The lower surface of the cushion block 20 abuts against the support tube 30 located below.

[0076] The four support tubes 30 are arranged in a cross shape to completely cover the bottom of the support frame assembly 3, so that the overall force on the support frame assembly 3 is uniform, and further the force on each first lifting rope 13 is more uniform. And the two ends of the multiple support tubes 30 do not interfere with each other, which is convenient for the normal operation of the adjustment assembly 6, and also convenient for the installation and use of the power assembly 4 and the handwheel assembly 5, improving the use comfort of the equipment. The lower surface of the base 2 abuts against the support tube 30 located above, and the lower surface of the cushion block 20 abuts against the support tube 30 located below, thereby realizing the control of the limit assembly 7.

[0077] The adjustment assembly 6 is arranged inside the support tube 30, and one is provided at each end of the support tube 30.

[0078] The adjusting assembly 6 includes an arc-shaped plate 61, a support base 62, a support roller 63, a vertical plate 64, and a lifting ring 65;

[0079] The support base 62 is fixed to the bottom of the support pipe 30. The vertical plates 64 are vertically fixed on both sides of the support base 62. The two ends of the support roller 63 are rotatably arranged on the vertical plates 64. A plurality of support rollers 63 are arranged along the arc direction. The arc-shaped plate 61 is slidably arranged inside the support pipe 30. The two sides of the arc-shaped plate 61 are abutted against the vertical plates 64. The arc-shaped plate 61 and the power assembly 4 form a transmission pair;

[0080] One end of the arc-shaped plate 61 is slidably inserted into the support pipe 30, and the bottom of the arc-shaped plate 61 presses against the circumferences of a plurality of support rollers 63;

[0081] The other end of the arc-shaped plate 61 extends out of the outside of the support pipe 30, and this end is fixedly connected to the lifting ring 65;

[0082] Among them, the lifting rings 65 at both ends of one support pipe 30 are respectively connected to the same first lifting ear 11 through two first lifting ropes 13, and this first lifting ear 11 is located directly above the support pipe 30.

[0083] When the base 2 is tilted, on one side of the lower end of the base 2, the arc-shaped plate 61 is extended outwards, and the corresponding first lifting rope 13 adjusts the force direction of the support pipe 30, thereby adjusting the tilt angle of the base 2 and the support frame assembly 3, and reducing the tilt angle of the base 2 and the support frame assembly 3;

[0084] Since the arc-shaped plate 61 is arc-shaped, when the arc-shaped plate 61 extends outwards, the top of the arc-shaped plate 61 moves upwards. The arc-shaped plate 61 forms a guardrail shape, which has a good protection effect and a good interception effect on the tower barrel components, thereby improving the safety of the tower barrel component hoisting.

[0085] The bottom of the arc-shaped plate 61 and the circumferences of the support rollers 63 form rolling friction to ensure the smooth movement of the arc-shaped plate 61; the two sides of the arc-shaped plate 61 are abutted against the vertical plates 64, and the vertical plates 64 limit the arc-shaped plate 61 to prevent the arc-shaped plate 61 from shaking laterally during the movement.

[0086] The lifting rings 65 at both ends of one support pipe 30 are respectively connected to the same first lifting ear 11 through two first lifting ropes 13, and this first lifting ear 11 is located directly above the support pipe 30, so as to ensure that the force conditions at both ends of each support pipe 30 only correspond to one first lifting ear 11, and the force conditions between multiple support pipes 30 do not interfere with each other, thereby facilitating the adjustment of the two adjusting assemblies 6 inside a single support pipe 30.

[0087] The power assembly 4 includes a rotating shaft 40, a driving gear 41, a ratchet 42, and a transmission wheel 43;

[0088] A first through hole 31 for the rotation shaft 40 to pass through is formed in the side wall of the support pipe 30. A bearing seat for installing the rotation shaft 40 is provided on the inner circumference of the first through hole 31, and a rack is fixed on the inner circumferential surface of the arc-shaped plate 61;

[0089] One end of the rotation shaft 40 extends into the support pipe 30 and is rotatably connected to the inner wall of the support pipe 30, and the other end of the rotation shaft 40 is located outside the support pipe 30;

[0090] The driving gear 41 is key-connected to the rotation shaft 40. The driving gear 41 is located inside the support pipe 30 and meshes with the arc-shaped plate 61;

[0091] The transmission wheel 43 is key-connected to the rotation shaft 40. The transmission wheel 43 is located outside the support pipe 30, and the transmission wheel 43 and the handwheel assembly 5 form a transmission pair;

[0092] The ratchet wheel 42 is key-connected to the rotation shaft 40. The ratchet wheel 42 is located inside the support pipe 30, and the limiting component 7 cooperates with the ratchet wheel 42 to form a limiting mechanism.

[0093] The operator rotates the rotation shaft 40 by rotating the handwheel assembly 5, so as to drive the arc-shaped plate 61 to move through the driving gear 41. The driving gear 41 presses the arc-shaped plate 61 to limit the arc-shaped plate 61, so as to prevent the arc-shaped plate 61 from shaking longitudinally and improve the stability of the movement of the arc-shaped plate 61.

[0094] A bearing seat for installing the rotation shaft 40 is provided on the inner circumference of the first through hole 31. The bearing seat has a good supporting effect to ensure the best stability of the rotation of the rotation shaft 40.

[0095] The ratchet wheel 42 is key-connected to the rotation shaft 40, and the limiting component 7 cooperates with the ratchet wheel 42 to form a limiting mechanism, so as to ensure that the rotation shaft 40 can only rotate in one direction, that is, the arc-shaped plate 61 can only extend outwards from the support pipe 30 and cannot retract into the support pipe 30, thereby ensuring the limitation of the position of the arc-shaped plate 61, avoiding the deformation of the arc-shaped plate 61, and improving the safety of equipment use.

[0096] The limiting component 7 includes a moving column 71, a first spring 72, a lever component 73, a fixing plate 75, a sliding plate 76, a second spring 77 and a limiting block 78;

[0097] A second through hole 32 is formed in the top of the support pipe 30. A guide pipe 33 is fixed at the position of the second through hole 32. The guide pipe 33 is located inside the support pipe 30. The moving column 71 is slidably arranged in the guide pipe 33. The first spring 72 is fixed at the bottom of the support pipe 30. The top of the first spring 72 is connected to the bottom of the moving column 71. A pressing head 74 is fixed in the middle of the moving column 71;

[0098] The fixed plate 75 is fixed inside the support tube 30. The sliding plate 76 is slidably arranged on the fixed plate 75 in the vertical direction. The lower end of the second spring 77 is fixed on the sliding plate 76, and the upper end of the second spring 77 is connected to the limit block 78. The limit block 78 is located directly below the large wheel 42.

[0099] The lever member 73 is fixed inside the support tube 30. One end of the lever member 73 is located below the pressure head 74, and the other end of the lever member 73 is located below the sliding plate 76.

[0100] The bottom of the base 2 and the cushion block 20 presses against the top of the corresponding support tube 30.

[0101] When the tower barrel component is placed on the base 2, the base 2 squeezes the support frame assembly 3, and the base 2 and the cushion block 20 squeeze the tops of the plurality of moving columns 71. The moving columns 71 slide downward in the guide tubes 33, and the first spring 72 is in a compressed state. The pressure head 74 presses one end of the lever member 73 downward, so that the other end of the lever member 73 drives the sliding plate 76 to move upward. At this time, the limit block 78 abuts against the ratchet wheel 42, and the second spring 77 is in a natural length state or a compressed state.

[0102] When the ratchet wheel 42 rotates in the predetermined direction, the circumferential surface of the ratchet wheel 42 squeezes the second spring 77 to rotate smoothly.

[0103] When the rotation direction of the ratchet wheel 42 is opposite to the predetermined direction, the side of the limit block 78 is stressed, which hinders the ratchet wheel 42 to prevent it from continuing to rotate.

[0104] After the tower barrel component is hoisted, unload the tower barrel component and remove the base 2 from the support frame assembly 3. At this time, under the action of the first spring 72, the moving columns 71 move upward, and then the sliding plate 76 moves downward. The ratchet wheel 42 is disengaged from the limit block 78, thereby unlocking the limit mechanism. At this time, the second spring 77 is in a natural length state, and the operator can reverse-rotate the rotating shaft 40 to retract the arc-shaped plate 61 into the support tube 30 to prepare for the next hoisting.

[0105] The limit block 78 is columnar, and a guide sleeve for guiding the limit block 78 is provided on the top of the fixed plate 75.

[0106] The guide sleeve ensures that the limit block 78 moves in the predetermined direction. At the same time, the guide sleeve can support the limit block 78 to improve the limit effect of the limit block 78 on the ratchet wheel 42.

[0107] An elastic pad is fixed on the lower surface of the base 2, and an elastic pad is fixed on the lower surface of the cushion block 20.

[0108] The elastic pad has a good buffering effect and plays a good protective role for the support pipe 30 and the limit block 78.

[0109] An elastic pad is fixed between the bottom of the support seat 62 and the support pipe 30.

[0110] The elastic pad has a good buffering effect and plays a good protective role for the support seat 62.

[0111] Both ends of the first suspension rope 13 and the second suspension rope 14 are connected with hooks.

[0112] The hooks facilitate quick connection with the lifting ring 65 and the first lifting lug 11, improving work efficiency.

[0113] The working principle of the present invention: Place the tower barrel component on the base 2, lift the base 2 and the support frame assembly 3 upward by a certain distance, and observe whether the base 2 is inclined;

[0114] When the base 2 is inclined, on one side of the lower end of the base 2, extend the arc-shaped plate 61 outward. The operator rotates the handwheel assembly 5 to rotate the rotating shaft 40, thereby driving the arc-shaped plate 61 to move through the driving gear 41.

[0115] Among them, the base 2 squeezes the support frame assembly 3, and the base 2 and the cushion block 20 squeeze the tops of the plurality of moving columns 71. The moving columns 71 slide downward in the guide pipe 33. The first spring 72 is in a compressed state. The pressing head 74 presses down one end of the lever member 73, so that the other end of the lever member 73 drives the sliding plate 76 to move upward; at this time, the limit block 78 abuts against the ratchet 42, and the second spring 77 is in a natural length state or a compressed state. When the ratchet 42 rotates in the predetermined direction, the circumferential surface of the ratchet 42 squeezes the second spring 77 to rotate smoothly. When the rotation direction of the ratchet 42 is opposite to the predetermined direction, the side of the limit block 78 is stressed, hindering the ratchet 42 to prevent it from continuing to rotate.

[0116] After the lifting of the tower barrel component is completed, unload the tower barrel component and remove the base 2 from the support frame assembly 3. At this time, under the action of the first spring 72, the moving columns 71 move upward, and then the sliding plate 76 moves downward. The ratchet 42 is disengaged from the limit block 78, thereby unlocking the limit mechanism. At this time, the second spring 77 is in a natural length state, and the operator can rotate the rotating shaft 40 in the reverse direction to adjust the arc-shaped plate 61 to retract into the support pipe 30 for the next lifting preparation.

[0117] In summary, in the present invention, the adjustment component 6 is adjusted through the power component 4 to change the stress angle of the first suspension rope 13, thereby adjusting the base 2, and most likely ensuring that the base 2 is in a horizontal state, thus improving the safety of lifting.

[0118] In the present invention, the four support tubes 30 are arranged in a cross shape to completely cover the bottom of the support frame assembly 3, so that the overall force on the support frame assembly 3 is uniform, and thus the force on each first lifting rope 13 is also more uniform. Moreover, the two ends of the multiple support tubes 30 do not interfere with each other, which facilitates the normal operation of the adjustment assembly 6 and also facilitates the installation and use of the power assembly 4 and the handwheel assembly 5, improving the comfort of using the equipment. The lower surface of the base 2 abuts against the upper support tube 30, and the lower surface of the cushion block 20 abuts against the lower support tube 30, thereby realizing the control of the limiting assembly 7.

[0119] In the present invention, the arc-shaped plate 61 is extended outwards, and the corresponding first lifting rope 13 adjusts the force direction of the support tube 30, thereby adjusting the inclination angles of the base 2 and the support frame assembly 3 and reducing the inclination angles of the base 2 and the support frame assembly 3. At the same time, the arc-shaped plate 61 is arc-shaped. When the arc-shaped plate 61 is extended outwards, the top of the arc-shaped plate 61 moves upwards. The arc-shaped plate 61 forms a guardrail shape, which has a good protection effect and a good interception effect on the tower barrel components, thereby improving the safety of hoisting the tower barrel components.

[0120] In the present invention, both sides of the arc-shaped plate 61 abut against the vertical plates 64, and the vertical plates 64 limit the arc-shaped plate 61 to prevent the arc-shaped plate 61 from swaying horizontally during movement. The driving gear 41 presses the arc-shaped plate 61 to limit the arc-shaped plate 61 to prevent the arc-shaped plate 61 from swaying longitudinally.

[0121] In the present invention, the lifting rings 65 at both ends of a support tube 30 are respectively connected to the same first lifting ear 11 through two first lifting ropes 13, and the first lifting ear 11 is located directly above the support tube 30 to ensure that the force conditions at both ends of each support tube 30 only correspond to one first lifting ear 11, and the force conditions between the multiple support tubes 30 do not interfere with each other, thereby facilitating the adjustment of the two adjustment assemblies 6 inside a single support tube 30.

[0122] In the present invention, the ratchet wheel 42 is key-connected to the rotating shaft 40, and the limiting assembly 7 is matched with the ratchet wheel 42 to form a limiting mechanism to ensure that the rotating shaft 40 can only rotate in one direction, that is, the arc-shaped plate 61 can only extend outwards from the support tube 30 and cannot retract into the support tube 30, thereby ensuring the limitation of the position of the arc-shaped plate 61 and avoiding the deformation of the arc-shaped plate 61 to improve the safety of using the equipment.

Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
