Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, and in particular to a four-track prefabricated concrete pavement panel hoisting equipment. Background Technology

[0002] Gantry cranes are a type of bridge crane, also known as portal cranes. They are mainly used for loading and unloading cargo and bulk materials in outdoor freight yards and material yards. Gantry cranes are characterized by high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in port freight yards. Their metal structure resembles a portal frame, with two legs installed under the main beam, allowing them to travel directly on ground-level tracks. The main beam may have cantilever beams extending outwards at both ends.

[0003] Concrete pavement panels refer to road slabs with cement concrete as the main material for the surface layer. During the production, handling, and construction of concrete pavement panels, lifting equipment such as gantry cranes or heavy-duty cranes is involved. Existing gantry crane devices mostly use guide rails installed on the road surface for movement. However, this method is limited by the guide rails, preventing the lifting equipment from being moved according to the road construction site. Furthermore, existing gantry crane devices are mostly supported by fixed brackets and lack height adjustment capabilities, limiting their applicability. Moreover, existing gantry crane devices only have X-axis or Y-axis movement capabilities, lacking angle adjustment functionality. When lifting concrete pavement panels, angle adjustment can only be achieved manually by rotating the hook and chain, a cumbersome process that increases the workload for construction workers, is prone to safety accidents, and reduces construction efficiency. Therefore, there is an urgent need for a four-track prefabricated concrete pavement panel lifting device to solve the aforementioned problems. Summary of the Invention

[0029] 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.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1: Reference Figure 1-6 This invention provides a four-track assembled concrete pavement panel hoisting device, including a hoisting main beam 1. Vertical adjustment mechanisms are fixedly connected to the four corners of the bottom end of the hoisting main beam 1. Support beams 2 are fixedly connected to the bottom ends of two vertical adjustment mechanisms located on the same side. The two support beams 2 are arranged in parallel. Moving mechanisms are installed on both sides of the bottom end of the support beams 2. The four moving mechanisms are located in the same plane. A sliding groove 3 is opened at the bottom end of the hoisting main beam 1. A transverse moving lifting beam 4 is slidably connected in the sliding groove 3. A first hydraulic cylinder 5 is fixedly connected to one side inside the sliding groove 3. The output end of the first hydraulic cylinder 5 is fixedly connected to the transverse moving lifting beam 4. A rotating mechanism is provided at the bottom end of the transverse moving lifting beam 4. A hoisting machine 6 is provided at the bottom end of the rotating mechanism. A balancing hoisting mechanism is provided on the hoisting machine 6. The balancing hoisting mechanism is correspondingly arranged with the concrete pavement panel.

[0032] To further optimize the design, in order to adjust the height of the device, the vertical adjustment mechanism includes a second hydraulic cylinder 7 fixedly connected to both sides of the top of the support beam 2. The top of the second hydraulic cylinder 7 is fixedly connected to the bottom of the hoisting main beam 1. The second hydraulic cylinder 7 drives the hoisting main beam 1 to move vertically, thereby raising and lowering it to suit hoisting situations of different heights and to facilitate transfer on the transport vehicle.

[0033] To further optimize the design, in order to move the device, the moving mechanism includes tracks 8 installed on both sides of the bottom end of the support beam 2. Several track wheels 9 are rotatably connected to the support beam 2, and all track wheels 9 are located inside the tracks 8 and are connected to the inner wall of the tracks 8. Hydraulic pumps 10 are fixedly connected to both support beams 2. The output shaft of the hydraulic pump 10 is fixedly connected to the middle of any track wheel 9. By controlling the moving mechanism on the two support beams 2 with two separate hydraulic pumps 10, the device can move linearly and can also be turned by reverse drive of the two hydraulic pumps 10. This avoids the limitation of gantry crane movement by sliding rails in the prior art, eliminates the need to repeatedly lay tracks and disassemble equipment on the construction site, reduces the workload of construction personnel, and improves construction efficiency.

[0034] To further optimize the design and achieve the rotation of the hoisting machine 6, an annular slide rail 34 is provided at the bottom center of the transverse moving beam 4. The rotation mechanism includes a connecting pipe 11 rotatably connected within the annular slide rail 34. An annular rotating disk 12 is fixedly connected to the outer wall of the connecting pipe 11. Several sector-shaped blocks 13 are fixedly connected at equal intervals along the circumference at the top of the annular rotating disk 12. A limiting groove 14 is provided between two adjacent sector blocks 13. An arc-shaped limiting block 15 is fixedly connected to the top of the sector block 13 on the side away from the connecting pipe 11. A driving component is provided at the bottom of the moving beam 4. The limiting groove 14 and the arc-shaped limiting block 15 are both connected to the driving component. A rotating component is provided at the bottom of the annular rotating disk 12. The rotating component is connected to the connecting pipe 11. The rotating component drives the annular rotating disk 12 to rotate, thereby achieving the rotation operation of the hoisting machine 6.

[0035] To further optimize the scheme, in order to drive the annular rotating disk 12, the driving component includes a motor 16 fixedly connected to the bottom end of the transverse moving lifting beam 4. The output end of the motor 16 is fixedly connected to a connecting rod 17, and the bottom end of the connecting rod 17 is fixedly connected to a fan-shaped slider 18. The fan-shaped slider 18 is adapted to the arc-shaped limiting block 15. The bottom end of the fan-shaped slider 18 is fixedly connected to one end of a limiting rod 19, and the other end of the limiting rod 19 is fixedly connected to a limiting cylinder 20. The limiting cylinder 20 is adapted to the limiting groove 14. The motor 16 drives the limiting rod 19 to slide in the limiting groove 14, thereby rotating the annular rotating disk 12. At the same time, the connecting pipe 11 is rotatably connected to the annular slide rail 34 to ensure the stability of the annular rotating disk 12 during rotation. In order to reduce friction, several guide wheels 35 are installed at equal intervals along the circumference on the outer wall of the connecting pipe 11. The guide wheels 35 rotate in the annular slide rail 34.

[0036] To further optimize the design, in order to reduce the impact force during rotation, one end of the first spring 21 is fixedly connected to the side of the limiting slide 14 away from the connecting pipe 11, and the other end of the first spring 21 abuts against the limiting cylinder 20. Since the concrete pavement is mostly made of heavy materials, in order to reduce the inertia generated by the panel during the cycle, the first spring 21 provides a certain buffering force on the limiting cylinder 20.

[0037] To further optimize the design and ensure the stability of the concrete pavement panel during rotation, the rotating component includes a first rotating ring 22 fixedly connected to the bottom of the annular rotating disk 12. Several first support plates 23 are fixedly connected at equal intervals along the circumference of the outer wall of the first rotating ring 22. A second rotating ring 24 is located at the bottom of the first rotating ring 22, and the second rotating ring 24 is axially staggered with the first rotating ring 22. Several second support plates 25 are fixedly connected at equal intervals along the circumference of the outer wall of the second rotating ring 24. The first support plates 23 and second support plates 25 are parallel and correspondingly arranged. A synchronizing element is provided on the outer wall of the connecting pipe 11. The second rotating ring 24 is drivenly connected to the first rotating ring 22 through the synchronizing element. A balancing element is provided between the first support plates 23 and the second support plates 25, and is drivenly connected to the balancing hoisting mechanism. The first support plates 23 and the second support plates 25 are staggered along the axis, ensuring the directional consistency and stability of the balancing element during rotation.

[0038] To further optimize the scheme, in order to achieve synchronous rotation of the first support plate 23 and the second support plate 25 and ensure that their rotation speed and direction are the same, the synchronizing element includes a first sprocket 26 fixedly connected to the outer wall of the connecting pipe 11, and a second sprocket 27 coaxially fixedly connected to the middle of the top end of the second rotating ring 24. The first sprocket 26 and the second sprocket 27 are connected by a chain 28. The top end of the second rotating ring 24 has an annular groove 29, and the bottom end of the connecting pipe 11 extends into the annular groove 29 and is slidably connected to the annular groove 29. The first sprocket 26, the second sprocket 27 and the chain 28 ensure the synchronous rotation of the first rotating ring 22 and the second rotating ring 24, thereby realizing the synchronous rotation of the first support plate 23 and the second support plate 25.

[0039] To further optimize the scheme and ensure the stability of the concrete pavement panel during rotation, the balancing component includes a balancing block 30 hinged to the bottom of the first support plate 23 on one side. The middle of the bottom of the balancing block 30 is hinged to the top of the second support plate 25. Several flexible connecting rods 31 are provided on the side of the bottom of the balancing block 30 away from the first support plate 23. The flexible connecting rods 31 are hinged to the bottom of the balancing block 30 at equal intervals around the circumference. The bottom of the flexible connecting rods 31 is connected to the balancing hoisting mechanism. The balancing blocks 30 are in a parallel state, and the hinge ends of the balancing blocks 30 and the flexible connecting rods 31 are in the same direction. During the cyclic rotation of the device, the flexible connecting rods 31 are stretched due to the inertia generated by the rotation, which has the effect of buffering the inertial force.

[0040] To further optimize the scheme and achieve stable hoisting that is compatible with the concrete pavement slab, the transmission connection of the balancing hoisting mechanism includes a detachable balance plate 32 connected to the output end of the hoisting machine 6. The top of the balance plate 32 is fixedly connected with hooks at equal intervals along the circumference. The bottom end of the flexible connecting rod 31 is hinged to the hooks. The bottom end of the balance plate 32 is hinged with several hooks 33 at equal intervals along the circumference. All the hooks 33 are compatible with the concrete pavement slab. The hoisting machine 6 connects the balance plate 32 with metal chains and bolts. During the rotation process, the balance plate 32 will be deflected by the inertial force of the concrete pavement slab. The inertial force generated is reduced by the flexible connecting rod 31.

[0041] The device of this invention is easy to adjust, transfer, and construct, and solves the problem of the limitation of gantry crane movement by the sliding rail in traditional technology. It realizes stable hoisting and aerial angle adjustment of concrete pavement panels, reduces the workload of construction workers, and improves construction efficiency.

[0042] Example 2: Reference Figure 7-8 The difference between this embodiment and embodiment one is that support pipes 36 are fixedly connected to both ends of the side of the support beam 2 away from the hoisting machine 6, support columns 37 are slidably connected inside the support pipes 36, and a support transmission mechanism is provided inside the support pipes 36. The support columns 37 are connected to the support transmission mechanism in a transmission connection.

[0043] The support transmission mechanism includes a track 38 fixedly connected to the inner wall of the support tube 36, a first moving block slidably connected within the track 38, one end of a first adjusting rod 39 hinged to the first moving block, a second moving block hinged to the first adjusting rod 39, the second moving block slidably connected to the top of the support column 37, an arc-shaped toothed groove 40 hinged to the inner wall of the support tube 36, one end of a second adjusting rod 41 fixedly connected to the arc-shaped toothed groove 40, the other end of the second adjusting rod 41 hinged to the top of the support column 37, the first adjusting rod 39 and the second adjusting rod 41 are arranged crosswise, and the middle parts of the first adjusting rod 39 and the second adjusting rod 41 are hinged together, a rotating shaft rotatably connected to the inner wall of the support tube 36, a first gear 42 fixedly connected to the rotating shaft, the first gear 42 meshing with the arc-shaped toothed groove 40, a drive motor fixedly connected to the inner wall of the support tube 36, a second bevel gear 43 fixedly connected to the output shaft of the drive motor, the first bevel gear 42 meshing with the second bevel gear 43.

[0044] The drive motor drives the second bevel gear 43 to rotate, which in turn drives the meshing first bevel gear 42 to rotate. The first bevel gear 42 drives the arc-shaped tooth groove 40 to rotate, and the rotation of the arc-shaped tooth groove 40 drives the fixedly connected second adjusting rod 41 to rotate. When the second adjusting rod 41 rotates, the first adjusting rod 39 drives the first moving block and the second moving block to slide. The first adjusting rod 39 gradually moves from an inclined state to a vertical state, which drives the support column 37 to move vertically. The four support columns 37 provide support for the entire hoisting equipment. On the one hand, when the support columns 37 are on the same horizontal plane as the bottom of the equipment, the equipment can be kept stable. On the other hand, the equipment can also be lifted off the ground, and the transport vehicle can be driven under the equipment to realize the rapid loading and transfer of the equipment.
