A hoisting equipment based on prefabricated module transfer

Abstract

This utility model proposes a hoisting device based on the transfer of prefabricated cabins, relating to the field of prefabricated cabin transfer technology. It includes a rotatable frame connected to the upper surface of a hoisting plate, an adjusting assembly on the frame, and a moving assembly on the hoisting plate. The moving assembly includes two fixed shells fixed to the outer side of the hoisting plate. This hoisting device places the hoisting plate on the upper surface of the prefabricated cabin. Then, by starting a first rotary motor, a bidirectional threaded rod is driven to rotate. The rotation of the bidirectional threaded rod causes the two moving plates to move closer together along the inner wall of the fixed shells, bringing them into contact with the outer side of the prefabricated cabin, limiting and stabilizing their position. Simultaneously, the hoisting rope is kept parallel to the hoisting hook on the prefabricated cabin. The hook on the hoisting rope is then connected to the hoisting hook on the prefabricated cabin, thereby reducing contact wear between the rope and the side of the cabin.

Description

Technical Field

[0001] This utility model relates to a hoisting device, specifically a hoisting device based on the transfer of prefabricated cabins, belonging to the field of prefabricated cabin transfer technology. Background Technology

[0002] With the rapid development of industries such as new energy, power equipment, hydrogen production systems, and communication base stations, prefabricated modular equipment is widely used in rapid on-site deployment projects. Prefabricated modules typically integrate equipment, electrical systems, piping, and control units into a standardized cabin, which is then hoisted, transported, and connected to the site for installation. Due to the large size, weight, and precision of the prefabricated modules, hoisting equipment is required for overall lifting and positioning during transport to ensure transportation safety and installation accuracy.

[0003] The hoisting process typically relies on cranes or gantry cranes in conjunction with wire ropes and slings for slinging. Therefore, the design of the hoisting equipment directly affects the safety and integrity of the prefabricated module during transport. However, existing hoisting methods for prefabricated modules often involve directly connecting ropes or wire ropes to the hoisting hooks at the bottom of the module and then using a crane for lifting and transport. During hoisting, the ropes may come into contact with and rub against the upper edge or outer wall of the prefabricated module due to changes in angle or force shift. This can easily cause the coating on the module's surface to peel off, corners to deform, and even affect the module's protective performance and appearance integrity. Furthermore, it is difficult to adjust the angle during the descent, requiring auxiliary or manual methods to lower it to the correct position, which is quite cumbersome.

[0004] Therefore, a hoisting device based on the transfer of prefabricated modules is proposed here. Summary of the Invention

[0005] This invention proposes a hoisting device based on the transfer of prefabricated cabins, which can adjust the position of the hoisting rope to keep it parallel to the position of the hoisting hook on the prefabricated cabin, so as to reduce the contact wear between the rope and the side of the cabin.

[0006] This utility model is achieved through the following technical solution: a hoisting device based on the transfer of prefabricated cabins, including a gantry rotatably connected to the upper surface of the hoisting plate, an adjustment component on the gantry, and a moving component on the hoisting plate.

[0007] The moving assembly includes two fixed shells fixed to the outside of the hanging plate. A first rotary motor is fixed to one side of one of the fixed shells. The output shaft end of the first rotary motor passes through the fixed shell and is fixed with a bidirectional threaded rod. The end of the bidirectional threaded rod away from the first rotary motor passes through the hanging plate and is rotatably connected to the inner wall of the other fixed shell. Movable plates are installed on the outer surfaces of the bidirectional threaded rod inside the two fixed shells, and the outer surfaces of the movable plates are slidably connected to the inner walls of the fixed shells.

[0008] Furthermore, the hanging plate is provided with a rotating groove, and the outer surface of the bidirectional threaded rod is rotatably connected to the inner wall of the rotating groove.

[0009] Furthermore, a lifting rope is fixed to the bottom end of the movable plate, and a lifting hook is fixed to the bottom end of the lifting rope.

[0010] Furthermore, the adjustment assembly includes a fixed sleeve rotatably connected to the outer surface of the hanger and a second rotary motor fixed to the outer surface of the hanger. The output end of the second rotary motor is fixed with a rotating shaft, the bottom end of the rotating shaft is fixed with a gear, and the outer surface of the fixed sleeve is fixed with a gear ring, and the gear meshes with the gear ring.

[0011] Furthermore, a mounting block is fixed to the outer surface of the hanger, and the second rotary motor is fixed to the outer surface of the hanger via the mounting block.

[0012] Furthermore, a limiting groove is formed on the outer surface of the hanger, and a limiting ring is fixed to the inner wall of the fixing sleeve, with the outer surface of the limiting ring rotatably connected to the inner wall of the limiting groove.

[0013] Furthermore, the upper surface of the hanger is fixed with multiple lifting lugs.

[0014] This utility model provides a hoisting device based on the transfer of prefabricated modules, which has the following beneficial effects: This hoisting equipment based on prefabricated cabin transfer places the lifting plate on the upper surface of the prefabricated cabin, and then drives the double-threaded rod to rotate by starting the first rotary motor. The rotation of the double-threaded rod can drive two moving plates to move along the inner wall of the fixed shell, so that the moving plates fit against the outer side of the prefabricated cabin, limiting and stabilizing its position. At the same time, the position of the hoisting rope and the hoisting hook on the prefabricated cabin are kept parallel. Then the hoisting hook on the hoisting rope is connected to the hoisting hook on the prefabricated cabin, thereby reducing the contact wear between the rope and the side of the cabin.

[0015] This hoisting equipment based on the transfer of prefabricated cabins drives the shaft and gears to rotate by starting the second rotary motor. The gears, through meshing with the gear ring, can drive the fixed sleeve to rotate along the outer surface of the hoist. The hoist can drive the prefabricated cabin to rotate through the hanging plate, thereby adjusting the angle of the prefabricated cabin during the hoisting and descent process.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

A first rotary motor 202 is fixed to one side of one of the fixed shells 201. The output shaft end of the first rotary motor 202 passes through the fixed shell 201 and is fixed with a bidirectional threaded rod 203. The end of the bidirectional threaded rod 203 away from the first rotary motor 202 passes through the hanging plate 1 and is rotatably connected to the inner wall of the other fixed shell 201. Movable plates 204 are installed on the outer surfaces of the bidirectional threaded rod 203 inside the two fixed shells 201, and the outer surface of the movable plates 204 is slidably connected to the inner wall of the fixed shell 201.

[0022] A rotating groove 207 is provided on the hanging plate 1, and the outer surface of the bidirectional threaded rod 203 is rotatably connected to the inner wall of the rotating groove 207.

[0023] A lifting rope 205 is fixed to the bottom end of the movable plate 204, and a lifting hook 206 is fixed to the bottom end of the lifting rope 205.

[0024] Place the lifting plate 1 on the upper surface of the prefabricated cabin, and then start the first rotary motor 202 to drive the bidirectional threaded rod 203 to rotate. The rotation of the bidirectional threaded rod 203 can drive the two moving plates 204 to move along the inner wall of the fixed shell 201, so that the moving plates 204 are in contact with the outer side of the prefabricated cabin, limiting and stabilizing their position. At the same time, keep the lifting rope 205 parallel to the position of the lifting hook on the prefabricated cabin, and then connect the lifting hook 206 on the lifting rope 205 to the lifting hook on the prefabricated cabin to reduce the contact wear between the rope and the side of the cabin.

[0025] Please refer to this carefully. Figure 2 and Figure 4 The adjustment component 3 includes a fixed sleeve 304 rotatably connected to the outer surface of the hanger 4 and a second rotary motor 301 fixed to the outer surface of the hanger 4. The output end of the second rotary motor 301 is fixed with a rotating shaft 302, and the bottom end of the rotating shaft 302 is fixed with a gear 303. The outer surface of the fixed sleeve 304 is fixed with a gear ring 305, and the gear 303 meshes with the gear ring 305.

[0026] The outer surface of the hanger 4 is fixed with a mounting block 5, and the second rotary motor 301 is fixed to the outer surface of the hanger 4 through the mounting block 5.

[0028] By starting the second rotary motor 301, the rotating shaft 302 is driven to rotate. The rotating shaft 302 can drive the gear 303 to rotate. The gear 303, through meshing with the gear ring 305, can drive the fixed sleeve 304 to rotate along the outer surface of the gantry 4. The gantry 4 can drive the prefabricated cabin to rotate through the hanging plate 1, thereby adjusting the angle of the prefabricated cabin during the hoisting and descent process.

[0029] In use, this utility model involves connecting the lifting lugs 401 on the gantry 4 to external lifting equipment, then placing the lifting plate 1 on the upper surface of the prefabricated cabin. The first rotary motor 202 is then activated to rotate the bidirectional threaded rod 203. The rotation of the bidirectional threaded rod 203 causes two movable plates 204 to move along the inner wall of the fixed shell 201, bringing the movable plates 204 into contact with the outer side of the prefabricated cabin, thus limiting and stabilizing their position. Simultaneously, the lifting rope 205 remains parallel to the lifting hook on the prefabricated cabin. Finally, the lifting... The hook 206 on the rope 205 is connected to the lifting hook on the prefabricated cabin to reduce the contact wear between the rope and the side of the cabin. When the prefabricated cabin is lowered, the second rotary motor 301 is started to drive the rotating shaft 302 to rotate. The rotating shaft 302 can drive the gear 303 to rotate. The gear 303 can drive the fixed sleeve 304 to rotate along the outer surface of the lifting frame 4 through meshing with the gear ring 305. The lifting frame 4 can drive the prefabricated cabin to rotate through the lifting plate 1, so that the angle of the prefabricated cabin can be adjusted in the second way during the lifting and lowering process.
