Description

Technical Field

[0001] This invention relates to a lifting device, and more particularly to a lifting device for a beam-moving machine with anti-sway synchronous control, belonging to the technical field of beam-moving machines. Background Technology

[0002] Beam movers are key equipment used in bridge precast beam yards for lifting, transferring and transporting concrete box girders. They are widely used in the construction of large-scale infrastructure such as high-speed railways and highway bridges. Currently, the lifting operation of beam movers is usually carried out by the slings on the overhead crane in conjunction with the lifting gear to lift and lower the beam. Its lifting system is generally equipped with multiple sets of winches and slings, and the lifting of the slings at both ends is controlled by independent electric drive mechanisms.

[0003] However, the independent drive method makes lifting stability control complex, and it is difficult to achieve precise coordinated lifting and lowering of the slings at both ends. In actual lifting, the beam often tilts or deflects due to asynchrony. In addition, during the movement of the beam, the lifting system and lifting equipment are subject to inertial forces such as acceleration, deceleration, start and stop, which can easily cause significant swaying, affecting operational safety and stability.

[0004] To address this issue, a sway-resistant synchronous control lifting device for the beam-moving machine was designed to optimize the aforementioned problems. Summary of the Invention

[0005] The main objective of this invention is to provide a sway-resistant synchronous control lifting device for a beam transporter, in order to solve the technical problems in existing beam transporter lifting operations where the independent drive of the slings at both ends makes it difficult to achieve precise coordinated lifting and lowering, resulting in beam tilting and deflection, and the beam easily swaying due to inertial forces during movement, thus affecting operational safety and stability.

[0006] The objective of this invention can be achieved by adopting the following technical solution: A beam lifting device with anti-sway synchronous control includes a crossbeam, outriggers set at the bottom of the crossbeam, movable wheels installed at the bottom of the outriggers, a crane slidably set on the crossbeam, slings set on the crane, and lifting devices connected to the bottom of the slings. The top of the crane is equipped with a winding mechanism for winding and unwinding the slings, and a synchronous drive mechanism is connected between the winding mechanisms at both ends of the crossbeam. The side of the lifting device is equipped with a hanging ring, and the inside of the outrigger is equipped with a guide ring. A wire rope is connected to the hanging ring by a hook. The wire rope passes through the guide ring and extends to the bottom of the crossbeam. A tensioning mechanism for tightening the wire rope is provided at the bottom of the crossbeam.

[0007] Preferably, the synchronous drive mechanism includes a driven bevel gear, a driving bevel gear, a spline sleeve, a spline shaft, a drive housing, a worm gear, a worm, and a drive motor; The driven bevel gear is mounted on the drive shaft of the winding mechanism, and the driving bevel gear meshes with the driven bevel gear; Spline sleeves are fixedly installed on the sides of the drive bevel gears, and the spline sleeves are rotatably mounted on the overhead crane. The drive chamber is located in the middle of the crossbeam, the drive motor is installed on the top of the crossbeam, the output end of the drive motor is connected to a worm, and the worm wheel is located in the drive chamber and meshes with the worm. The worm gear is connected to a splined shaft at both ends. The end of the splined shaft away from the worm gear passes through the inside of the splined sleeve. A through hole that mates with the splined shaft is provided at the middle position of the driving bevel gear.

[0008] By combining the self-locking characteristics of the worm gear with bevel gear transmission, precise synchronous drive of the winding mechanisms at both ends can be achieved, and it also has a reverse self-locking function to prevent the sling from being released unexpectedly, thereby improving the safety and synchronization accuracy of the lifting process.

[0009] Preferably, the winding mechanism includes a winding bin, a first drum, and a first reducer; The winding bin is located on the top of the overhead crane. The first drum is rotatably installed inside the winding bin. A first reducer is installed at one end of the first drum, and a driven bevel gear is installed on the drive shaft of the first reducer.

[0010] By integrating the winding mechanism into the top of the crane and cooperating with the first reducer for transmission, stable winding and unwinding of the sling can be achieved in a limited space. The structure is compact and the transmission efficiency is high.

[0011] Preferably, limit plates are fixed at both ends of the top of the crossbeam, and the end of the spline shaft is rotatably connected to the limit plates through bearings.

[0012] By using a limiting plate to support and limit the end of the spline shaft, it is possible to effectively prevent the long-distance spline shaft from flexing and deforming and axial movement during rotation, thus ensuring the smoothness and reliability of power transmission.

[0013] Preferably, the tensioning mechanism includes a guide roller, a second drum, a second reducer, and a take-up / discharge mechanism; The guide rollers are symmetrically installed at the middle position of the bottom of the crossbeam, and the guide rollers are parallel to the width direction of the crossbeam. The second drum is rotatably installed at the middle position of the bottom of the crossbeam, and the second drum is parallel to the guide rollers. The top of the wire rope passes over the top of the guide roller and is wound around the second drum. One end of the second drum is connected to the second reducer. The take-up and discharge machine is installed on the side of the crossbeam, and the second reducer is connected to the take-up and discharge machine in a drive connection.

[0014] The wire rope can be flexibly tightened and loosened through an independent tensioning mechanism, which can adjust the tension in real time according to the beam specifications and working conditions. It is highly adaptable and easy to operate.

[0015] Preferably, the two wire ropes at the same end of the crossbeam are distributed in a crisscross pattern, and the two wire ropes are respectively connected to the hanging rings on both sides of the lifting device.

[0016] By arranging the steel wire ropes in an X-shape, the beam can be subjected to bidirectional constraints in both the longitudinal and lateral directions from the diagonal direction, which is more effective in preventing swaying than the parallel arrangement method.

[0017] Preferably, the guide ring is fixedly installed on the inner wall of the support leg, and the lateral distance between the two sets of guide rings on the inner side of the two support legs at one end of the crossbeam is less than or equal to the width of the beam. The wire rope passes through the interior of the guide ring and slides with the guide ring.

[0018] By using guide rings to guide and limit the steel wire rope, and ensuring that the spacing between the guide rings matches the width of the beam, it is possible to ensure that the steel wire rope accurately fits the side of the beam after tensioning, forming an effective lateral compression constraint.

[0019] Preferably, a collar is fixed at the corresponding spline shaft penetration point on both sides of the drive compartment and the overhead crane, and the spline shaft passes through the inside of the collar and fits against the inner side of the collar.

[0020] By using collars to support and guide the spline shaft through the piercing section, it is possible to ensure that the spline shaft maintains good coaxiality during operation, reduce radial runout and frictional loss, and extend the service life of transmission components.

[0021] Preferably, a traveling motor is installed on both sides of the bottom of the crane, and a traveling wheel is installed at the output end of the traveling motor, and the traveling wheel meshes with the bottom of the crossbeam for transmission.

[0022] The crane's position can be flexibly adjusted by using a traveling motor and traveling wheels, which can adapt to the hoisting needs of beams with different widths and spans, thus improving the versatility of the device.

[0023] Preferably, the outer sides of multiple sets of wire ropes are covered with wear-resistant sheaths, and the wear-resistant sheaths are fitted to the outer side of the beam.

[0024] By isolating the wire rope from direct contact with the beam through a wear-resistant sheath, the wear of the wire rope can be effectively reduced, the surface quality of the beam can be protected, the service life of the wire rope can be extended, and scratches on the beam can be avoided.

[0025] The beneficial effects of this invention are as follows: This invention provides a sway-resistant synchronous control lifting device for a beam-moving machine. It utilizes a winding mechanism consisting of a winding bin, a first drum, and a first reducer, installed at the top of the gantry crane. This mechanism works in conjunction with a synchronous drive mechanism composed of a driven bevel gear, a driving bevel gear, a splined sleeve, a splined shaft, a drive bin, a worm gear, a worm shaft, and a drive motor. The driven bevel gear is mounted on the drive shaft of the first reducer. During operation, the drive motor drives the worm gear via the worm shaft, and the power is synchronously transmitted to the driving bevel gears at both ends of the beam through the splined shaft and splined sleeve. The driving bevel gears drive the driven bevel gears, thus achieving synchronous drive of the winding mechanisms at both ends. This ensures that the first drum synchronously winds up and unwinds the slings, effectively preventing beam tilting or deflection caused by asynchronous lifting at both ends, and improving the stability and synchronization accuracy of the lifting process.

[0026] By installing hanging rings on the side of the lifting device and guide rings on the inside of the outriggers, the hooks at the ends of the wire ropes hook onto the hanging rings, and the wire ropes pass through the guide rings. The two wire ropes at the same end of the crossbeam are distributed in a crisscross pattern. With the help of the tensioning mechanism, the top of the wire ropes is tightened and limited. During the movement of the beam-moving machine, the slings vertically suspend the beam and bear the main load in the vertical direction. The wire ropes apply a downward pulling force to the beam from both sides. At the same time, the wire ropes adhere to and squeeze the sides of the beam, forming a multi-directional constraint effect. This can effectively suppress the swaying of the beam caused by the acceleration, deceleration and inertial forces of movement, and improve the stability and safety during the lifting and moving process.

[0027] The tensioning mechanism, consisting of guide rollers, a second drum, a second reducer, and a take-up and discharge machine, can flexibly adjust the tension of the wire rope according to the actual working conditions, adapting to the hoisting needs of beams of different specifications. It is easy to operate and has a wide range of applications. Attached Figure Description

Detailed Implementation

[0030] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0031] Example 1: As Figures 1-9 As shown, this embodiment provides a beam lifting device with anti-sway synchronous control, including a crossbeam 1, a support leg 2 set at the bottom of the crossbeam 1, a moving wheel 201 installed at the bottom of the support leg 2, a crane 3 slidably set on the crossbeam 1, a sling 4 set on the crane 3, and a lifting device 7 connected to the bottom end of the sling 4. The top of the overhead crane 3 is equipped with a winding mechanism 5 for winding and unwinding the sling 4, and a synchronous drive mechanism 6 is connected between the winding mechanisms 5 at both ends of the crossbeam 1. The side of the lifting device 7 is provided with a hanging ring 8, and the inside of the outrigger 2 is provided with a guide ring 9. A wire rope 11 is connected to the hanging ring 8 by a hook 10. The wire rope 11 passes through the guide ring 9 and extends to the bottom of the crossbeam 1. A tensioning mechanism 12 for tightening the wire rope 11 is provided at the bottom of the crossbeam 1.

[0032] When the lifting device of the beam-moving machine is working, the synchronous drive mechanism 6 first provides power, and transmits the power synchronously to the winding mechanism 5 at both ends of the crossbeam 1 through its internal transmission components. The winding mechanism 5 moves synchronously, driving the first drum 502 to synchronously wind up and unwind the sling 4, thereby realizing the smooth lifting and lowering of the lifting device 7 and the beam it carries, ensuring that the lifting speed and displacement of the sling 4 at both ends are consistent, and avoiding tilting or deflection of the beam during the lifting process.

[0033] After the beam is lifted into position by the sling 4, the hook 10 at the end of the wire rope 11 is attached to the hanging ring 8 on the side of the lifting device 7. The middle part of the wire rope 11 passes through the guide ring 9 fixed to the inside of the outrigger 2, and its upper end passes over the guide roller 1201 in the tensioning mechanism 12 at the bottom of the crossbeam 1 and is wound onto the second drum 1202. The take-up and discharge motor 1204 is started, and the second drum 1202 is driven to rotate through the second reducer 1203 to wind and tension the wire rope 11, so that the wire rope 11 is in a taut state. At this time, the wire rope 11 applies a downward pulling force to the beam from both sides, while pressing against and squeezing the sides of the beam, forming a multi-directional constraint together with the vertically suspended sling 4.

[0034] When the beam mover moves via the moving wheels 201, the wire rope 11 continuously provides horizontal restraint, effectively suppressing the inertial swaying of the beam caused by acceleration, deceleration, and start / stop. When it is necessary to release the beam, the wire rope 11 is first released in reverse by the retractor 1204, then the hook 10 is removed from the hanging ring 8, and finally the sling 4 is released by the winding mechanism 5 controlled by the synchronous drive mechanism 6, lowering the beam to the target position.

[0035] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. See the description below for details: In this embodiment, the synchronous drive mechanism 6 includes a driven bevel gear 601, a driving bevel gear 602, a spline sleeve 603, a spline shaft 604, a drive chamber 605, a worm gear 606, a worm 607, and a drive motor 608. Driven bevel gear 601 is mounted on the drive shaft of winding mechanism 5, and driving bevel gear 602 meshes with driven bevel gear 601; Spline sleeves 603 are fixedly installed on the sides of the drive bevel gear 602, and the spline sleeves 603 are rotatably mounted on the overhead crane 3; The drive chamber 605 is located in the middle of the crossbeam 1, the drive motor 608 is installed on the top of the crossbeam 1, the output end of the drive motor 608 is connected to the worm 607, and the worm wheel 606 is rotatably located in the drive chamber 605 and meshes with the worm 607. The worm gear 606 is connected to a splined shaft 604 at both ends. The end of the splined shaft 604 away from the worm gear 606 passes through the inside of the splined sleeve 603. A through hole that mates with the splined shaft 604 is provided at the middle position of the drive bevel gear 602.

[0036] When the synchronous drive mechanism 6 is working, the drive motor 608 starts, and its output shaft drives the worm gear 607 to rotate. The worm gear 607 drives the worm wheel 606, which meshes with it, to rotate within the drive chamber 605. Since splined shafts 604 are fixedly connected to both ends of the worm wheel 606, the splined shafts 604 rotate synchronously with the worm wheel 606. The splined shaft 604 passes through the through hole in the middle of the driving bevel gear 602 and engages with the splined inner wall of the splined sleeve 603. When the splined shaft 604 rotates, it drives the splined sleeve 603 to rotate synchronously. The splined sleeve 603 drives the driving bevel gear 602, which is fixed to it, to rotate. The driving bevel gear 602 transmits power to the driven bevel gear 601, which meshes with it. The driven bevel gear 601 is mounted on the drive shaft of the winding mechanism 5, thus inputting power to the winding mechanism 5. Because the worm 607 and worm wheel 606 have self-locking characteristics, when the drive motor 608 stops working, the worm wheel 606 is locked, which can effectively prevent the sling 4 from being released unexpectedly due to gravity and ensure lifting safety.

[0037] In this embodiment, the winding mechanism 5 includes a winding chamber 501, a first drum 502, and a first reducer 503; The winding chamber 501 is located on the top of the overhead crane 3. The first drum 502 is rotatably disposed inside the winding chamber 501. A first reducer 503 is installed at one end of the first drum 502, and a driven bevel gear 601 is installed on the drive shaft of the first reducer 503.

[0038] When the winding mechanism 5 is working, the driven bevel gear 601 transmits power to the drive shaft of the first reducer 503. After being reduced in speed and increased in torque by the first reducer 503, the first drum 502 is driven to rotate within the winding chamber 501. The rotation of the first drum 502 causes the sling 4 wound on it to be wound or unwound. When the first drum 502 rotates clockwise, the sling 4 is wound and the lifting device 7 rises; when the first drum 502 rotates counterclockwise, the sling 4 is unwound and the lifting device 7 descends. The winding mechanisms 5 at both ends operate simultaneously under the drive of the synchronous drive mechanism 6, realizing the synchronous winding and unwinding of the sling 4 at both ends.

[0039] In this embodiment, limit plates are fixed at both ends of the top of the crossbeam 1, and the end of the spline shaft 604 is rotatably connected to the limit plates through bearings.

[0040] The limiting plate supports and limits the end of the spline shaft 604, ensuring that the spline shaft 604 maintains a stable axial position during rotation, preventing the spline shaft 604 from flexing or axially moving due to its large length, and ensuring the smoothness and reliability of power transmission.

[0041] In this embodiment, the tensioning mechanism 12 includes a guide roller 1201, a second drum 1202, a second reducer 1203, and a take-up and discharge motor 1204; Guide rollers 1201 are symmetrically installed at the middle position of the bottom of the crossbeam 1, and the guide rollers 1201 are parallel to the width direction of the crossbeam 1. The second drum 1202 is rotatably installed at the middle position of the bottom of the crossbeam 1, and the second drum 1202 is parallel to the guide rollers 1201. The top end of the wire rope 11 passes over the top of the guide roller 1201 and is wound on the second drum 1202. One end of the second drum 1202 is connected to the second reducer 1203. The take-up and discharge motor 1204 is installed on the side of the crossbeam 1, and the second reducer 1203 and the take-up and discharge motor 1204 are connected in a transmission.

[0042] When the tensioning mechanism 12 is working, the take-up and release motor 1204 starts, and its power is transmitted to the second drum 1202 after being reduced in speed and increased in torque by the second reducer 1203, driving the second drum 1202 to rotate. When the second drum 1202 rotates, it winds up or releases the wire rope 11. The top of the wire rope 11 is led out from the second drum 1202 and passes over the top of the guide roller 1201. The guide roller 1201 changes the direction of the wire rope 11, so that the wire rope 11 extends smoothly from the middle position of the bottom of the crossbeam 1 to the direction of the guide rings 9 on both sides. When it is necessary to restrain the beam from swaying, the take-up and release motor 1204 rotates forward, and the second drum 1202 winds up the wire rope 11 to tension it; when it is necessary to release the beam, the take-up and release motor 1204 rotates in reverse, and the second drum 1202 releases the wire rope 11 to loosen it for easy removal of the hook 10.

[0043] In this embodiment, the two steel wire ropes 11 at the same end of the crossbeam 1 are distributed in a cross pattern, and the two steel wire ropes 11 are respectively connected to the hanging rings 8 on both sides of the lifting device 7.

[0044] The two wire ropes 11 at the same end of the crossbeam 1 are arranged in a crisscross pattern. The left wire rope 11 passes through the right guide ring 9 and connects to the right hanging ring 8 of the lifting device 7, while the right wire rope 11 passes through the left guide ring 9 and connects to the left hanging ring 8 of the lifting device 7. This crisscross arrangement creates an X-shape below the beam. When the wire ropes 11 are tensioned, they exert a pulling force on the beam from opposite directions. Compared to a parallel arrangement, this provides more comprehensive horizontal constraint and effectively suppresses the beam's swaying in both the longitudinal and transverse directions.

[0045] In this embodiment, the guide ring 9 is fixedly installed on the inner wall of the support leg 2, which guides and limits the steel wire rope 11 passing through it. The lateral distance between the two sets of guide rings 9 on the inner side of the two support legs 2 at one end of the crossbeam 1 is less than or equal to the width of the beam, so that the steel wire rope 11 can pass around the outer side of both sides of the beam after passing through the guide ring 9. This ensures that the steel wire rope 11 can fit against the side of the beam when tensioned, forming an effective lateral compression and constraint on the beam. The steel wire rope 11 passes through the interior of the guide ring 9 and slides with the guide ring 9. The guide ring 9 constrains the position of the steel wire rope 11, so that it extends along a predetermined path.

[0046] In this embodiment, a collar is fixed at the corresponding spline shaft 604 through-hole on both sides of the drive compartment 605 and the overhead crane 3. The spline shaft 604 passes through the inside of the collar and fits against the inner side of the collar.

[0047] The collar supports and guides the spline shaft 604, ensuring that the spline shaft 604 remains coaxial at the position through the drive chamber 605 and the overhead crane 3, preventing radial runout or friction with the bore wall during rotation, and ensuring the stability of power transmission and the service life of transmission components.

[0048] In this embodiment, both sides of the bottom of the overhead crane 3 are equipped with a traveling motor, and the output end of the traveling motor is equipped with a traveling wheel, which meshes with the bottom of the crossbeam 1 for transmission.

[0049] When the overhead crane 3 moves, the traveling motor starts, and its output drives the traveling wheels to rotate. The traveling wheels mesh with the rack or track surface at the bottom of the crossbeam 1, and the overhead crane 3 moves along the length of the crossbeam 1 through meshing transmission. The traveling motors on both sides control the movement of the overhead crane 3 at their respective ends, so that the overhead crane 3 can flexibly adjust its position on the crossbeam 1 to meet the hoisting requirements of beams of different sizes.

[0050] In this embodiment, wear-resistant sheaths are fitted on the outer sides of multiple sets of wire ropes 11, and the wear-resistant sheaths are in contact with the outer side of the beam.

[0051] When the wire rope 11 is tensioned and attached to the side of the beam, the wear-resistant sleeve directly contacts the beam surface, bearing the friction between the wire rope 11 and the beam. Made of highly wear-resistant material, the wear-resistant sleeve effectively reduces wear between the wire rope 11 and the beam, extending the service life of the wire rope 11. It also prevents the wire rope 11 from directly contacting the beam and causing scratches or indentations on the beam surface, thus protecting the beam's appearance and structural integrity.

[0052] The solutions in Embodiment 1 and Embodiment 2 will be further described below with reference to their specific working methods. When the lifting device of the beam-moving machine is working, the lifting device 7 is first connected and fixed to the beam body, so that the sling 4 and the wire rope 11 are both in a slack state. The drive motor 608 is started, and the drive motor 608 drives the worm gear 607 to rotate. The worm gear 607 drives the worm wheel 606 to rotate in the drive chamber 605. The worm wheel 606 drives the spline shafts 604 at both ends to rotate synchronously. The spline shafts 604 drive the driving bevel gear 602 to rotate through the spline sleeve 603. The driving bevel gear 602 transmits power to the driven bevel gear 601 that meshes with it. The driven bevel gear 601 inputs power to the drive shaft of the first reducer 503. After the first reducer 503 reduces the speed and increases the torque, it drives the first drum 502 to rotate synchronously in the winding chamber 501, so that the first drums 502 at both ends of the beam 1 simultaneously wind up the sling 4, realizing the smooth lifting of the lifting device 7 and the beam body. Since the two drums are driven by the same power source through the synchronous drive mechanism 6, the speed of the sling 4’s winding and unwinding is completely consistent with the stroke, effectively preventing the beam from tilting or deflecting during the lifting process.

[0053] After the beam is lifted into position, the hook 10 at the end of the wire rope 11 is attached to the hanging ring 8 on the side of the lifting device 7. The middle part of the wire rope 11 passes through the guide ring 9 inside the outrigger 2, and the top end passes over the guide roller 1201 at the middle position of the bottom of the crossbeam 1 before being wound onto the second drum 1202. The take-up and discharge motor 1204 is started, and the second drum 1202 is driven to rotate through the second reducer 1203 to wind and tension the wire rope 11, so that the wire rope 11 is in a taut state. At this time, the two wire ropes 11 at the same end of the crossbeam 1 are distributed in a cross pattern, and the two wire ropes 11 are connected to the hanging rings 8 on both sides of the lifting device 7 from diagonal directions, forming an X-shaped arrangement below the beam. After the wire rope 11 is tensioned, a downward pulling force is applied to the beam from both sides, and at the same time, the wear-resistant sleeve on the outside of the wire rope 11 is attached to the side of the beam, forming a lateral compression constraint on the beam.

[0054] When the beam-moving machine travels along the prefabrication yard via the moving wheels 201, the beam tends to sway due to inertia during acceleration, deceleration, and start-stop operations. At this time, the vertically suspended slings 4 bear the main load in the vertical direction of the beam, while the cross-arranged tension wire ropes 11 provide horizontal restraint forces to the beam from multiple directions, effectively suppressing the swaying of the beam in both the longitudinal and transverse directions. Simultaneously, the self-locking characteristics of the worm gear 607 and worm wheel 606 ensure that the first drum 502 remains locked after the drive motor 608 stops, preventing the slings 4 from being released unexpectedly. The traveling motor at the bottom of the overhead crane 3 drives the traveling wheels to mesh with the bottom of the crossbeam 1, allowing for flexible adjustment of the overhead crane 3 position to adapt to different lifting requirements. The guide rollers 1201 guide the wire ropes 11, the collar supports and guides the spline shaft 604, and the limiting plate provides limiting support to the end of the spline shaft 604, collectively ensuring the coordinated and stable operation of all components of the device.

[0055] Once the beam is transported to the target location, the retractor 1204 reverses, releasing the wire rope 11 to loosen it, and removes the hook 10 from the hanging ring 8, releasing the wire rope 11 from the beam. Subsequently, the drive motor 608 reverses, driving the first drum 502 to synchronously release the sling 4, smoothly lowering the beam to the designated position, completing the entire hoisting operation.

[0056] The above description is merely a further 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 disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
