Description

Technical Field

[0001] This utility model relates to the field of hoisting, and in particular to a hoisting device for steel structure construction. Background Technology

[0002] In modern construction, steel is widely used in various building projects due to its high strength and lightweight characteristics. However, due to its large size and weight, traditional manual handling methods can no longer meet the actual needs. Therefore, the industry has introduced various types of hoisting equipment to assist in construction. These devices not only improve work efficiency but also effectively reduce labor costs and ensure construction safety.

[0003] A steel beam hoisting tool for steel structure workshops, disclosed in Chinese Utility Model 2 (Announcement No.: CN118458579B), includes a steel beam, a fixed structure, a drive structure, a limiting structure, a wire rope, a winding structure, and a suspension structure. The winding structure winds up the wire rope, thereby changing the distance between the drive structure and the suspension structure. This allows for adjustment of the wire rope length when hoisting different types of steel beams. After use, the fixed structure and the suspension structure can be connected, making overall storage more convenient.

[0004] In the process of realizing this utility model, the inventors discovered that the technology has at least the following problems: during the process of hoisting steel with wire ropes, if a strong wind is encountered, the steel is prone to swaying in the air, causing certain safety hazards. Therefore, a steel structure construction hoisting device is now proposed. Utility Model Content

[0005] To address the safety hazard posed by steel swaying in the air during steel hoisting via wire ropes in the event of strong winds, this invention provides a steel structure construction hoisting device.

[0006] This utility model provides a steel structure construction hoisting device, which adopts the following technical solution:

[0007] A steel structure construction hoisting device includes a hoisting box slidably connected to the bottom of a crane. A motor is fixedly installed on one side of the hoisting box. A rotating rod is fixedly installed at the output end of the motor, passing through the hoisting box. The end of the rotating rod away from the motor is rotatably connected to the inner side wall of the hoisting box. A winding drum is fixedly sleeved on the outer surface of the rotating rod. A hook is fixedly installed at the wire release end of the winding drum. An installation plate is fixedly installed on the outer surface of the hook. A distance sensor is fixedly installed on the top of the installation plate. A controller is fixedly installed on the outer surface of the hoisting box. The distance sensor is electrically connected to the controller.

[0008] The inner top wall of the hoisting box is fixedly installed with a multi-stage electric push rod, which is electrically connected to the controller. A connecting block is fixedly installed at the vertically downward telescopic end of the multi-stage electric push rod. A shock-absorbing shell is provided at the bottom of the connecting block. A shock absorber is fixedly installed on the inner wall of the shock-absorbing shell. A telescopic plate is fixedly installed at one end of the shock absorber.

[0009] By adopting the above technical solution, when hoisting steel, the distance sensor can transmit real-time data to the controller. The controller can then activate the multi-stage electric push rod after the steel has risen to a certain height, according to the set program. The multi-stage electric push rod can drive the connecting block and the shock absorber to move downwards, descending to the vicinity of the upper surface of the steel according to the distance measured by the distance sensor. When encountering strong winds, the steel will sway and touch the telescopic plate on the upper surface. The telescopic plate can push the shock absorber to contract, and the shock absorber can buffer and dampen the force, thereby reducing the large-amplitude swaying of the steel during movement.

[0010] Optionally, a plug rod is fixedly installed on one side of the shock-absorbing shell, a slot adapted to the plug rod is opened inside the connecting block, a spring is fixedly installed inside the connecting block, a movable plate is fixedly installed at one end of the spring, a limiting rod is fixedly passed through the movable plate, and a limiting groove adapted to the limiting rod is opened inside the plug rod.

[0011] By adopting the above technical solution, during use, the operator can pull the moving plate by the limit rod. The limit rod can squeeze the spring through the moving plate and separate from the limit groove, so that the operator can quickly remove the shock absorber shell and repair or replace the shock absorber shell or the structure connected to the shock absorber shell.

[0012] Optionally, a protective shell is fixedly installed on one side of the hoisting box, and the motor is located inside the protective shell.

[0013] By adopting the above technical solution, the protective shell can protect the motor, reduce the impact of external objects on the motor, and extend the service life of the motor.

[0014] Optionally, a first slider is fixedly installed on each of the opposite sides of the movable plate, and a first groove adapted to the first slider is opened inside the connecting block.

[0015] By adopting the above technical solution, the first slider and the first groove can limit the movement range of the moving plate, and at the same time make the moving plate move more smoothly.

[0016] Optionally, a rubber shock-absorbing pad is fixedly installed on the outer side of the telescopic plate.

[0017] By adopting the above technical solution, the rubber shock-absorbing pad can buffer the force it receives, avoid hard contact between the steel and the telescopic plate, and play a certain protective role for the telescopic plate.

[0018] Optionally, one end of the limiting rod extends through to the outside of the connecting block and is fixedly connected with a pull ring.

[0019] By adopting the above technical solution, the pull ring allows staff to easily move the limit bar.

[0020] Optionally, a second slider is fixedly installed on each of the opposite sides of the telescopic plate, and a second groove adapted to the second slider is provided inside the shock-absorbing shell.

[0021] By adopting the above technical solution, the second slider and the second slide can limit the movement range of the telescopic plate, and at the same time make the telescopic plate move more smoothly.

[0022] Optionally, the end of the limiting rod away from the pull ring is provided with a downward-sloping guide angle.

[0023] By adopting the above technical solution, when installing the shock absorber shell, the insertion rod on the shock absorber shell can push the limiting rod to move through the guide angle, so that the shock absorber shell can be quickly fixed to the connecting block.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. In use, the operator can start the motor, which drives the rotating rod to rotate, which in turn drives the winding drum to rotate. The wire rope wound on the winding drum can move the hook downward to fix the steel. The distance sensor can transmit real-time data to the controller. The controller can activate the multi-stage electric push rod after the steel rises to a certain height according to the set program. The multi-stage electric push rod can drive the connecting block and the shock absorber to move downward. According to the distance measured by the distance sensor, it descends to the vicinity of the upper surface of the steel. When encountering strong winds, the steel will sway and touch the telescopic plate on the upper surface. The telescopic plate can push the shock absorber to retract. The shock absorber can buffer and dampen the force, thereby reducing the large-amplitude swaying of the steel when it moves.

[0026] 2. In use, this utility model allows workers to pull the pull ring to move, which in turn moves the limiting rod. The limiting rod then moves the moving plate, and the limiting rod can squeeze the spring through the moving plate and separate from the limiting groove. This allows workers to quickly remove the shock absorber shell and inspect or replace the shock absorber shell or the structure connected to it. Attached Figure Description

[0036] Please refer to Figure 1 and Figure 3 A multi-stage electric push rod 9 is fixedly installed on the inner top wall of the hoisting box 1. The multi-stage electric push rod 9 is electrically connected to the controller 8. During use, the controller 8 can adjust the extension and retraction degree of the multi-stage electric push rod 9 according to the measurement data of the distance sensor 7. A connecting block 10 is fixedly installed on the vertically downward extension end of the multi-stage electric push rod 9. A shock-absorbing shell 11 is provided at the bottom of the connecting block 10. A shock absorber 12 is fixedly installed on the inner wall of the shock-absorbing shell 11. A telescopic plate 13 is fixedly installed at one end of the shock absorber 12. A rubber shock-absorbing pad 20 is fixedly installed on the outer side of the telescopic plate 13.

[0037] Please refer to Figure 1 and Figure 3 The telescopic plate 13 is fixedly installed with second sliders 22 on both sides. The shock-absorbing shell 11 has a second groove adapted to the second sliders 22. The second sliders 22 and the second groove can limit the movement range of the telescopic plate 13 and make the telescopic plate 13 move more smoothly.

A limiting groove adapted to the limiting rod 17 is provided inside the rod 14. First sliders 19 are fixedly mounted on opposite sides of the movable plate 16. A first sliding groove adapted to the first slider 19 is provided inside the connecting block 10. The first sliders 19 and the first sliding groove limit the movement range of the movable plate 16 and make its movement more stable.

[0039] Please refer to Figure 1 and Figure 4 One end of the limiting rod 17 extends through the outside of the connecting block 10 and is fixedly connected to a pull ring 21, which allows the operator to easily move the limiting rod 17.

The rotating rod 3 drives the winding drum 4 to rotate, and the steel wire rope wound on the winding drum 4 drives the hook 5 to move downwards to fix the steel. The distance sensor 7 can transmit real-time data to the controller 8. According to the set program, after the steel rises to a certain height, the controller 8 can activate the multi-stage electric push rod 9. The multi-stage electric push rod 9 can drive the connecting block 10 and the shock-absorbing shell 11 to move downwards, descending to the upper surface of the steel according to the distance measured by the distance sensor 7. In the vicinity, when encountering strong winds, the steel swaying will touch the telescopic plate 13 on the upper surface. The telescopic plate 13 can push the shock absorber 12 to retract. The shock absorber 12 can buffer and dampen the force, thereby reducing the large-scale swaying of the steel when it moves. As the steel rises, the distance sensor 7 measures the change in distance from the hoisting box 1. The controller 8 can adjust the telescopic distance of the multi-stage electric push rod 9 according to the change in measured distance, thereby reducing the large-scale swaying of the steel when encountering strong winds during hoisting and improving hoisting safety.

[0041] In use, the operator can pull the pull ring 21 to move it. The pull ring 21 can drive the limit rod 17 to move, and the limit rod 17 can pull the moving plate 16 to move. The limit rod 17 can squeeze the spring 15 through the moving plate 16 and separate from the limit groove, so that the operator can quickly remove the shock absorber shell 11 and repair or replace the shock absorber shell 11 or the structure connected to the shock absorber shell 11.
