[0028] The movable beam is provided with a mounting housing, the mounting housing is provided with a mounting cavity, the movable beam is disposed in the mounting cavity, and the mounting housing is provided with multiple sets of lifting lugs.

[0029] A method for using a highly stable lifting device for concrete pipe pile molds includes the following steps:

[0030] S1. Single hoisting:

[0031] The moving beam is moved above the lower mold, and the moving shell is moved to adjust its position until each set of lower mold running wheel half rings has a corresponding moving shell. At the same time, the moving shell moves towards the lower mold, causing the first clamping component and the second clamping component to move towards the lower mold. The lower mold is clamped by the second clamping component, and the moving beam is lifted and moved, which drives the lower mold to be lifted and moved.

[0032] S2, Secondary hoisting:

[0033] The moving beam is moved above the steel cage, and the moving shell is moved toward the steel cage, causing the first clamping assembly and the second clamping assembly to move toward the steel cage. The second clamping assembly clamps the steel cage and moves it to the lower formwork of S1, and then pours concrete into the lower formwork.

[0034] S3, Three-stage hoisting:

[0035] The moving beam is moved above the upper mold, and the moving shell is moved towards the upper mold, causing the first clamping component and the second clamping component to move towards the upper mold. The first clamping component clamps the upper mold and moves the upper mold to the lower mold of S2. The upper and lower molds then wrap the steel cage.

[0036] S4, Four-stage hoisting:

[0037] After S3 is completed, the upper mold and the lower mold are connected, the moving beam is moved above the upper mold, and the moving shell is moved towards the upper mold, so that the first clamping assembly and the second clamping assembly are moved towards the upper mold. The upper mold is clamped by the first clamping assembly, and the lower mold is clamped by the second clamping assembly, and the upper mold is moved to other processing areas.

[0038] S5. Lower mold clamping alignment:

[0039] In S1 and S4, when the second clamping assembly clamps the lower mold, the lower mold running wheel half ring is inserted into the limiting groove of the clamping plate;

[0040] S6. Upper mold clamping alignment:

[0041] In S3 and S4, when the first clamping assembly clamps the upper mold, the two sets of first clamping claws extend into the two sets of clamping slots respectively.

[0042] S7. Lower mold hoisting and reinforcement:

[0043] After S5 is completed, the two outermost sets of movable shells move towards the center of the moving beam, and the lower mold is locked and reinforced by the pulling of the two sets of movable shells.

[0044] S8. Upper mold hoisting and reinforcement:

[0045] After S6 is completed, the two outermost sets of movable shells move toward the center of the moving beam, and the upper mold is locked and reinforced by the pulling of the two sets of movable shells.

[0046] S9, Extrusion Positioning:

[0047] In S2, S3, and S4, when the first clamping assembly and the second clamping assembly operate simultaneously, the extrusion screw descends, causing the extrusion plate to descend until the extrusion plate contacts the workpiece for clamping and positioning.

[0048] S10, Adjustment Processing:

[0049] In S1, if the second clamping component cannot clamp the lower mold, the distance between the clamping plate and the arc plate is adjusted until the clamping plate can be placed on the lower mold for clamping.

[0050] Compared with the prior art, the beneficial effects of the present invention are:

[0051] By simultaneously clamping the pipe pile mold with the first and second clamping components described above, the lifting device can firmly hold the pipe pile mold during lifting and transportation, preventing the mold from shaking or slipping, and improving the safety and stability of the operation. Furthermore, the first and second clamping components can clamp different positions of the pipe pile mold, enabling multi-directional clamping during lifting. This evenly distributes the weight of the mold, reducing offset and tilting during lifting, and further improving the stability of the lifting device. Attached Figure Description

Detailed Implementation

[0070] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0071] Example:

[0072] like Figure 1-17 As shown, this embodiment proposes a highly stable lifting device for concrete pipe pile molds, used to lift the pipe pile mold 30, including a movable beam 13, on which multiple sets of movable shells 20 are provided;

[0073] The movable housing 20 is provided with an mounting plate 28, and a drive screw 29 is rotatably mounted on the mounting plate 28. The movable housing 20 is also provided with a first clamping assembly 40 and a second clamping assembly 50. The drive screw 29 is connected to the first clamping assembly 40 and the second clamping assembly 50. The pipe pile mold 30 is provided with an upper mold 36 and a lower mold 32. When the drive screw 29 rotates, the first clamping assembly 40 clamps on the upper mold 36, and the second clamping assembly 50 clamps on the lower mold 32.

[0074] In this embodiment, when the pipe pile mold 30 is lifted, the movable housing 20 first moves, causing multiple sets of movable housings 20 to be positioned above the pipe pile mold 30. Then, the movable beam 13 descends, causing multiple sets of movable housings 20 to move toward the pipe pile mold 30. During the displacement, the first clamping assembly 40 and the second clamping assembly 50 open. When the movable housing 20 is suspended above the pipe pile mold 30, the first clamping assembly 40 and the second clamping assembly 50 close, simultaneously clamping the pipe pile mold 30. Then, the movable beam 13 moves, thereby causing the pipe pile mold 30 to move and adjust its position.

[0075] Of course, during the process of lifting the pipe pile mold 30, the two outermost sets of movable shells 20 move towards the center of the movable beam 13. The pipe pile mold 30 is positioned by the pulling of the two sets of movable shells 20, which can prevent the pipe pile mold 30 from shaking during the lifting process.

[0076] By using the first clamping component 40 and the second clamping component 50 as described above to clamp the pipe pile mold 30 simultaneously, the lifting device can firmly clamp the pipe pile mold 30 during lifting and transportation, achieving a double insurance effect, avoiding the shaking and slippage of the pipe pile mold 30, and improving the safety and stability of the operation.

[0077] The first clamping component 40 and the second clamping component 50, as described above, simultaneously clamp the pipe pile mold 30. The first clamping component 40 and the second clamping component 50 can clamp the pipe pile mold 30 at different positions respectively. During the hoisting process, the pipe pile mold 30 can be clamped in multiple directions, which can evenly distribute the weight of the mold, reduce the offset and tilt during the hoisting process, and further improve the stability of the hoisting equipment.

[0078] By adjusting the displacement of the movable housing 20 on the movable beam 13 as described above, it can be ensured that multiple sets of movable housings 20 can be accurately positioned above the pipe pile mold 30. In this way, the hoisting and moving position of the mold can be precisely controlled during operation. At the same time, it can be adjusted accordingly under different operating environments and requirements, making it highly adaptable and able to meet the hoisting requirements of concrete pipe pile molds 30 of different sizes and specifications.

[0079] The first clamping component 40 and the second clamping component 50, as described above, simultaneously clamp the pipe pile mold 30. Through this integrated design, the operation of the first clamping component 40 and the second clamping component 50 is unified into a single drive screw 29 system, which reduces the number of required drive components and simplifies the overall structure. This not only helps to reduce the complexity of design and manufacturing but also reduces the difficulty and cost of maintenance.

[0080] Specifically, the drive screw 29 is provided with a first threaded outer wall 291 and a second threaded outer wall 293. The first threaded outer wall 291 is threaded with a first connecting sleeve 292, and the second threaded outer wall 293 is threaded with a second connecting sleeve 294. The pitch of the first threaded outer wall 291 is smaller than the pitch of the second threaded outer wall 293.

[0081] The first connecting sleeve 292 is connected to the first clamping assembly 40, and the second connecting sleeve 294 is connected to the second clamping assembly 50.

[0082] In this embodiment, when clamping the pipe pile mold 30, the drive screw 29 rotates. Through the threaded engagement of the first threaded outer wall 291 with the first connecting sleeve 292 and the threaded engagement of the second threaded outer wall 293 with the second connecting sleeve 294, the first connecting sleeve 292 and the second connecting sleeve 294 are simultaneously raised or lowered, thereby causing the first clamping assembly 40 and the second clamping assembly 50 to simultaneously close or open.

[0083] Of course, since the pitch of the outer wall 291 of the first thread is smaller than the pitch of the outer wall 293 of the second thread, the first clamping component 40 and the second clamping component 50 can clamp the pipe pile mold 30 simultaneously under the same operation steps, reducing the complexity of operation, improving work efficiency, significantly optimizing the operation performance of the lifting device, improving its adaptability, flexibility and accuracy, and also helping to reduce manufacturing and maintenance costs.

[0084] Of course, the thread pitch of the outer wall of the first thread 291 and the outer wall of the second thread 293 is set according to the actual use. By simply adjusting the rotation of the drive screw 29, the ideal clamping position and force can be achieved, thereby improving the adaptability and efficiency of the lifting device.

[0085] Of course, the clamping force of the first clamping component 40 and the second clamping component 50 can also be precisely adjusted to ensure that appropriate clamping force can be provided for pipe pile molds 30 of different sizes and weights. This design provides greater flexibility and adaptability and is suitable for a wide range of application scenarios.

[0086] Specifically, two sets of first mounting rods 26 are symmetrically arranged on the movable housing 20;

[0087] The first clamping assembly 40 includes two sets of first clamping claws 41. The first clamping claws 41 are rotatably mounted on the first mounting rod 26. A first connecting plate 42 is provided on the first clamping claws 41. A first connecting rod 43 is movably disposed between the first connecting plate 42 and the first connecting sleeve 292.

[0088] The first connecting sleeve 292 is raised, and the first clamping claw 41 rotates around the axis of the first mounting rod 26 via the first connecting rod 43, and moves toward the axis of the driving screw 29 to clamp the upper mold 36.

[0089] In this case, when the first connecting sleeve 292 is lifted, since both sets of first connecting rods 43 are connected to the first connecting sleeve 292, both sets of first clamping claws 41 simultaneously move toward the axis of the drive screw 29 to perform a clamping process on the upper mold 36.

[0090] In this embodiment, when the first clamping assembly 40 clamps the pipe pile mold 30, the drive screw 29 rotates, causing the first connecting sleeve 292 to rise. The first connecting rod 43 drives the first clamping claw 41 to rotate around the axis of the first mounting rod 26. When the two sets of symmetrically arranged first clamping claws 41 simultaneously contact the pipe pile mold 30, the clamping process is completed. Of course, when it is necessary to release the clamp, the drive screw 29 rotates in the opposite direction, causing the first connecting sleeve 292 to fall.

[0091] Specifically, two sets of second mounting rods 27 are symmetrically arranged on the movable housing 20;

[0092] The second clamping assembly 50 includes two sets of second clamping claws 52. A second connecting plate 51 is provided on the second clamping claw 52. The second connecting plate 51 is rotatably mounted on the second mounting rod 27. A second connecting rod 53 is movably arranged between the second clamping claw 52 and the second connecting sleeve 294.

[0093] The second connecting sleeve 294 is raised, and the second clamping claw 52 rotates around the axis of the second mounting rod 27 via the second connecting rod 53, and moves toward the axis of the driving screw 29 to clamp the lower mold 32.

[0094] In this case, when the second connecting sleeve 294 is lifted, since both sets of second connecting rods 53 are connected to the second connecting sleeve 294, both sets of second clamping claws 52 simultaneously move toward the axis of the drive screw 29 to perform a clamping process on the lower mold 32.

[0095] In this embodiment, when the second clamping assembly 50 clamps the pipe pile mold 30, the drive screw 29 rotates, causing the second connecting sleeve 294 to rise. The second connecting rod 53 drives the second clamping claw 52 to rotate around the axis of the second mounting rod 27. When the two sets of symmetrically arranged second clamping claws 52 simultaneously contact the pipe pile mold 30, the clamping process is completed. Of course, when it is necessary to release the clamp, the drive screw 29 rotates in the opposite direction, causing the second connecting sleeve 294 to descend.

[0096] Specifically, the upper mold 36 is provided with multiple sets of upper mold running wheel semi-rings 37, and the lower mold 32 is provided with multiple sets of lower mold running wheel semi-rings 31. The multiple sets of upper mold running wheel semi-rings 37 are adapted to the multiple sets of lower mold running wheel semi-rings 31. The upper mold 36 is symmetrically provided with two sets of upper mold tongue and groove plates 34, and the lower mold 32 is symmetrically provided with two sets of lower mold tongue and groove plates 33. The two sets of upper mold tongue and groove plates 34 are adapted to the two sets of lower mold tongue and groove plates 33.

[0097] The central axis of the two sets of first clamping claws 41 is perpendicular to the central axis of the two sets of second clamping claws 52;

[0098] Clamping grooves 35 are provided on both end faces of the upper mold running wheel semi-ring 37 and the lower mold running wheel semi-ring 31. The two sets of first clamping claws 41 extend into the two sets of clamping grooves 35 respectively to clamp the upper mold 36. The two sets of second clamping claws 52 extend into the lower mold tongue and groove plates 33 respectively to clamp the lower mold 32.

[0099] In this embodiment, when the pipe pile mold 30 is hoisted, the first clamping claw 41 extends into the clamping groove 35 to clamp the upper mold 36, and the second clamping claw 52 extends into the lower mold tongue and groove plate 33 to clamp the lower mold 32.

[0100] Of course, the upper mold 36 can be clamped by the first clamping claw 41 alone. In this step, the upper mold 36 can be raised by a shim to facilitate the second clamping claw 52 to extend under the upper mold 36.

[0101] Of course, the lower mold 32 can also be clamped separately by the second clamping claw 52. In this step, the first clamping claw 41 is in an unloaded state, that is, the first clamping claw 41 moves toward the axis of the drive screw 29, but does not participate in the clamping process.

[0102] Specifically, a support plate 297 is provided at the bottom end of the drive screw 29, the drive screw 29 is rotatably mounted on the support plate 297, and a support rod 298 is provided between the support plate 297 and the movable housing 20;

[0103] The support plate 297 has a pressing threaded hole 295, and a pressing screw 65 with threaded engagement is provided in the pressing threaded hole 295. The bottom end of the pressing screw 65 is provided with a movable plate 63, and multiple sets of guide rods 64 are provided on the movable plate 63. Multiple sets of guide holes 296 are provided on the support plate 297, and the multiple sets of guide rods 64 are adapted to the multiple sets of guide holes 296.

[0104] Specifically, the inner cavity of the extrusion screw 65 is hollow, and the movable plate 63 is provided with a movable rod 62. The movable rod 62 extends into the inner cavity of the extrusion screw 65 and is slidably disposed on the extrusion screw 65.

[0105] The bottom end of the movable rod 62 is provided with a pressing plate 60, and a pressing spring 61 is provided on the pressing plate 60. The pressing spring 61 is sleeved on the outer wall of the movable rod 62 and is also connected to the movable plate 63. The first clamping claw 41 is provided with a communicating groove 411.

[0106] The drive screw 29 rotates, causing the extrusion screw 65 to move toward the upper die 36 until the extrusion plate 60 contacts the upper die 36 through the connecting groove 411.

[0107] In this embodiment, during the rotation of the drive screw 29, the extrusion screw 65 extends into the extrusion threaded hole 295 and simultaneously moves. When the first clamping assembly 40 and the second clamping assembly 50 clamp the pipe pile mold 30, the extrusion screw 65 moves toward the pipe pile mold 30, causing the extrusion plate 60 to contact the pipe pile mold 30 and press the pipe pile mold 30, thereby improving the stability during the clamping process.

[0108] Of course, by sliding the movable rod 62 within the cavity of the extrusion screw 65, and with the support of the extrusion spring 61, the extrusion plate 60 and the pipe pile mold 30 can change from the original rigid contact to elastic contact, avoiding damage to the pipe pile mold 30 caused by rigid contact. It also has a certain buffering effect, which can alleviate the impact force during clamping and movement, further protecting the pipe pile mold 30. Moreover, it can adapt to the hoisting needs of pipe pile molds 30 of different sizes and specifications, meet the usage requirements in different operating scenarios, and improve the flexibility and adaptability of the lifting equipment.

[0109] Specifically, the second gripper 52 includes an arc-shaped plate 521, the second connecting plate 51 is disposed on the arc-shaped plate 521, and the second connecting rod 53 is connected to the arc-shaped plate 521;

[0110] The arc-shaped plate 521 is provided with an extended receiving groove 5212, and an extended plate 5231 is slidably disposed in the extended receiving groove 5212. The extended plate 5231 is adapted to the extended receiving groove 5212. A clamping plate 523 is provided on the extended plate 5231, and a limiting groove 524 is provided on the clamping plate 523. The width of the limiting groove 524 is greater than the width of the lower mold running wheel semi-ring 31.

[0111] The arc-shaped plate 521 has multiple sets of positioning holes A5211, and the extended plate 5231 has multiple sets of positioning holes B5232. The multiple sets of positioning holes A5211 and multiple sets of positioning holes B5232 are matched in position and size, and positioning bolts 522 are provided between the positioning holes A5211 and positioning holes B5232.

[0112] In this embodiment, the cooperation between the arc plate 521 and the extended plate 5231 allows the clamping plate 523 to be extended, which facilitates clamping of lower molds 32 of different specifications.

[0113] When making adjustments, simply pull the extension plate 5231 out of the extension receiving groove 5212 and then fix it with the positioning bolt 522. At the same time, when the clamping plate 523 contacts the lower mold 32, the lower mold running wheel semi-ring 31 is placed in the limiting groove 524 to improve the stability of the hoisting.

[0114] Specifically, the movable housing 20 is provided with a movable cavity 21, and a drive motor 22 is provided in the movable cavity 21. The drive motor 22 is connected to the drive screw 29 in a transmission connection.

[0118] A method for using a highly stable lifting device for concrete pipe pile molds includes the following steps:

[0119] S1. Single hoisting:

[0120] The moving beam 13 is moved above the lower mold 32, and the moving housing 20 is moved and adjusted until each set of lower mold running wheel half rings 31 corresponds to a moving housing 20. At the same time, the moving housing 20 moves towards the lower mold 32, causing the first clamping component 40 and the second clamping component 50 to move towards the lower mold 32. The lower mold 32 is clamped by the second clamping component 50, and the moving beam 13 is lifted and moved, which drives the lower mold 32 to be lifted and moved.

[0121] S2, Secondary hoisting:

[0122] The movable beam 13 is moved above the steel cage, and the movable shell 20 is moved toward the steel cage, so that the first clamping assembly 40 and the second clamping assembly 50 are moved toward the steel cage. The steel cage is clamped by the second clamping assembly 50 and moved to the lower formwork 32 of S1, and concrete is poured into the lower formwork 32.

[0123] S3, Three-stage hoisting:

[0124] The movable beam 13 is moved above the upper mold 36, and the movable shell 20 is moved toward the upper mold 36, causing the first clamping assembly 40 and the second clamping assembly 50 to move toward the upper mold 36. The first clamping assembly 40 clamps the upper mold 36 and moves the upper mold 36 to the lower mold 32 of S2. The upper mold 36 and the lower mold 32 wrap the steel cage.

[0125] S4, Four-stage hoisting:

[0126] After S3 is completed, the upper mold 36 and the lower mold 32 are connected, the moving beam 13 is moved above the upper mold 36, and the moving housing 20 is moved toward the upper mold 36, so that the first clamping assembly 40 and the second clamping assembly 50 are moved toward the upper mold 36. The first clamping assembly 40 clamps the upper mold 36, and the second clamping assembly 50 clamps the lower mold 32, and drives the upper mold 36 to move to other processing areas.

[0127] S5. Lower mold clamping alignment:

[0128] In S1 and S4, when the second clamping assembly 50 clamps the lower mold 32, the lower mold running wheel half ring 31 is inserted into the limiting groove 524 of the clamping plate 523;

[0129] S6. Upper mold clamping alignment:

[0130] In S3 and S4, when the first clamping assembly 40 clamps the upper mold 36, the two sets of first clamping claws 41 extend into the two sets of clamping slots 35 respectively.

[0131] S7. Lower mold hoisting and reinforcement:

[0132] After S5 is completed, the two outermost movable shells 20 move toward the center of the movable beam 13, and the lower mold 32 is locked and reinforced by the pulling of the two movable shells 20.

[0133] S8. Upper mold hoisting and reinforcement:

[0134] After S6 is completed, the two outermost movable shells 20 move toward the center of the movable beam 13, and the upper mold 36 is locked and reinforced by the pulling of the two movable shells 20.

[0135] S9, Extrusion Positioning:

[0136] In S2, S3, and S4, when the first clamping assembly 40 and the second clamping assembly 50 operate simultaneously, the extrusion screw 65 descends, causing the extrusion plate 60 to descend until the extrusion plate 60 contacts the object for clamping and positioning.

[0137] S10, Adjustment Processing:

[0138] In S1, if the second clamping assembly 50 cannot clamp the lower mold 32, the distance between the clamping plate 523 and the arc plate 521 is adjusted until the clamping plate 523 can be placed on the lower mold 32 for clamping.

[0139] In this embodiment, the objects in S9 are the steel cage in S2, the upper mold 36 in S3, and the upper mold 36 in S4. In S3, when the upper mold 36 is lifted, multiple sets of pads can be placed at the bottom of the upper mold 36 to create a gap between the upper mold 36 and the ground, which facilitates the first clamping component 40 to perform the clamping process on the upper mold 36.

[0140] By clamping the pipe pile mold 30, precise positioning, stable clamping and reinforcement of the pipe pile mold 30 and the reinforcing cage can be achieved, ensuring the safety, stability and integrity of each component during hoisting and movement, thereby optimizing the entire hoisting operation, improving work efficiency and reducing mold damage.

[0141] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
