Description

Technical Field

[0001] The utility model relates to a hoisting device, in particular to an auxiliary hoisting device for steel structure construction. Background Art

[0002] During the traditional steel structure construction process, many problems faced seriously affect the smooth progress of the construction. When hoisting large components such as I-beams, a large amount of manpower is often required. Numerous construction workers work together to carry and fix, etc., which greatly increases the labor cost. At the same time, the complex operation process makes the construction process extremely cumbersome. From the preliminary preparation work to the actual hoisting operation, each link needs to be carefully arranged and executed meticulously.

[0003] This traditional construction method undoubtedly greatly increases the construction difficulty. Construction workers not only have to face heavy physical labor, but also have to constantly pay attention to the accuracy of each operation step. A slight carelessness may cause problems in the entire construction process. Moreover, there are relatively large safety risks during the construction process, especially in the case of high-altitude operations. The high-altitude environment itself is somewhat dangerous, and coupled with the large weight of large components such as I-beams, once there is a slipping phenomenon, it is very likely to cause serious accidents, posing a huge threat to the lives of construction workers.

[0004] In addition, the traditional manual operation method consumes a considerable amount of time. Operators need to spend a lot of time on various adjustment and fixing work. From selecting the appropriate fixing tools to actually installing, each step may take a lot of time. Moreover, this manual operation method also requires operators to have certain skills and experience. Only those construction workers who have received special training and have rich experience can operate more proficiently. However, this restricts the construction efficiency and quality to a certain extent. If the skill level of the operator is not high enough, or the experience is insufficient, it may lead to errors during the operation process, thereby affecting the construction progress and quality.

[0005] Therefore, there is an urgent need for a better auxiliary hoisting device for steel structure construction on the market currently. Content of the Utility Model

[0030] On both wing parts of the upper U-shaped bracket 4, a first hook-shaped plate body 6 and a second hook-shaped plate body 7 are rotatably arranged through a hinge shaft connection. Between the top of the first hook-shaped plate body 6 and the top of the second hook-shaped plate body 7, they are rotationally matched through a hinge shaft connection. The protruding direction of the first hook-shaped part 8 at the lower part of the first hook-shaped plate body 6 faces the second hook-shaped part 9 at the lower part of the second hook-shaped plate body 7, and the protruding direction of the second hook-shaped part 9 at the lower part of the second hook-shaped plate body 7 faces the first hook-shaped part 8 at the lower part of the first hook-shaped plate body 6. A first anti-slip rubber pad 10 is arranged on the first hook-shaped part 8, and a second anti-slip rubber pad 11 is arranged on the second hook-shaped part 9;

[0031] A first installation through hole 12 is arranged on the first hook-shaped plate body 6, and a second installation through hole 13 is arranged on the second hook-shaped plate body 7; a core secondary electric telescopic rod 14 is rotatably arranged in the first installation through hole 12 through a hinge shaft connection.

[0032] On the outer side of the back of the first hook-shaped plate body 6, a storage battery housing 15 and a controller 16 are fixedly provided. A lithium battery is installed in the storage battery housing 15. The controller 16 is electrically connected to the lithium battery in the storage battery housing 15, the controller 16 is electrically connected to the core secondary electric telescopic rod 14, and the controller 16 is connected to an external control terminal.

[0033] The user uses the hook of the crane to hook the middle connecting piece 1, and then moves the whole device to a suitable position.

[0034] Let the second hook portion 9 at the lower part of the second hook-shaped plate body 7 and the first hook portion 8 at the lower part of the first hook-shaped plate body 6 jointly hook the upper wing portion of the I-beam. The core secondary electric telescopic rod 14 contracts to hook the upper wing portion of the I-beam; the core secondary electric telescopic rod 14 extends to release the I-beam. The operation is simple.

[0035] I. Preparation work:

[0036] Equipment inspection:

[0037] Carefully check the middle connecting piece 1 to ensure that it has no damage such as deformation or cracks and can withstand the pulling force during the hoisting process.

[0038] Check the pulling rope 2 to confirm that it has no problems such as wear or broken wires and ensure that the strength of the pulling rope is sufficient.

[0039] Check the I-beam fixing mechanism 3, especially check whether the upper U-shaped bracket 4 is firm and whether the connection between the connecting ring body 5 and the pulling rope 2 is reliable. At the same time, check whether the rotation of the first hook-shaped plate body 6 and the second hook-shaped plate body 7 is flexible and whether there is jamming at the hinge shaft. Confirm that the first anti-slip rubber pad 10 on the first hook portion 8 and the second anti-slip rubber pad 11 on the second hook portion 9 are intact and can play an anti-slip role. Check whether the telescopic of the core secondary electric telescopic rod 14 is normal and whether the hinge connection with the first installation through hole 12 and the second installation through hole 13 is firm. Check whether the lithium battery in the storage battery housing 15 has sufficient power and whether the connection between the controller 16 and the external control terminal is stable.

[0040] II. Operations before hoisting:

[0041] Connect the crane:

[0042] Carefully hook the hook of the crane onto the middle connecting piece 1 to ensure a firm connection and prevent it from falling off during the hoisting process.

[0043] Operate the crane and slowly move the whole device to a suitable position near the I-beam to be hoisted.

[0044] III. Fix the I-beam:

[0045] Adjust the position of the hook-shaped plate body:

[0046] Send a command through an external control terminal to control the core secondary electric telescopic rod 14 to contract. Since the core part of the core secondary electric telescopic rod 14 is rotationally matched with the first mounting through hole 12 through a hinge shaft, and the end of the telescopic part is rotationally matched with the second mounting through hole 13 through a hinge shaft, the extended telescopic rod will drive the first hook-shaped plate body 6 and the second hook-shaped plate body 7 to rotate around the hinge shaft with the upper U-shaped bracket 4, causing the first hook part 8 and the second hook part 9 to open.

[0047] According to the size and shape of the I-beam, adjust the opening angle to ensure that the upper wing part of the I-beam can be smoothly placed between the hook parts.

[0048] Clamp the I-beam:

[0049] Align the opened first hook part 8 and second hook part 9 with the upper wing part of the I-beam, and slowly move the device to make the hook parts close to the I-beam.

[0050] After the first hook part 8 and the second hook part 9 come into contact with the I-beam, operate the core secondary electric telescopic rod 14 to shorten through an external control terminal. As the telescopic rod shortens, the first hook-shaped plate body 6 and the second hook-shaped plate body 7 gradually close, and the first hook part 8 and the second hook part 9 tightly clamp the upper wing part of the I-beam. The first anti-slip rubber pad 10 and the second anti-slip rubber pad 11 can increase the friction with the I-beam and prevent the I-beam from sliding during hoisting.

[0051] IV. Conduct hoisting operations:

[0052] Start the crane:

[0053] After confirming that the I-beam is firmly clamped, operate the crane to start the hoisting operation. The crane hoists the I-beam upward through the pulling rope 2 and slowly moves it to the designated position.

[0054] During the hoisting process, always pay attention to the operation status of the equipment, such as the tension of the pulling rope, the stability of the I-beam fixing mechanism, the status of the core secondary electric telescopic rod 14, etc. If any abnormal situation is found, immediately stop the hoisting and conduct inspections and handling.

[0055] V. Release the I-beam:

[0056] Stop the crane:

[0057] When the I-beam is hoisted to the designated position, operate the crane to stop the hoisting operation and ensure that the I-beam is stably placed at the target position.

[0058] Loosen the hook-shaped plate body:

[0059] Operate the core secondary electric telescopic rod 14 to extend through an external control terminal. The telescopic rod that contracts will drive the first hook-shaped plate body 6 and the second hook-shaped plate body 7 to open, so that the first hook-shaped part 8 and the second hook-shaped part 9 release the upper flank part of the I-beam.

[0060] Remove the equipment:

[0061] Remove the I-beam fixing mechanism 3 from the I-beam, and operate the crane to move the entire device to a safe position.

[0062] VI. Equipment storage:

[0063] Organize the equipment:

[0064] Arrange the pull rope 2 well to avoid entanglement and damage. Check components such as the middle connecting piece 1 and the I-beam fixing mechanism 3 to ensure they are clean and free of debris.

[0065] Proper storage:

[0066] Store the equipment in a dry and ventilated place, avoiding damage to the equipment caused by direct sunlight and humid environment. Regularly check and maintain the equipment to ensure it can operate normally during the next use.

[0067] In terms of safety:

[0068] This equipment is equipped with a special I-beam fixing mechanism, in which the first hook-shaped part 8 and the second hook-shaped part 9 cooperate with each other, and a first anti-slip rubber pad 10 is provided on the first hook-shaped part 8, and a second anti-slip rubber pad 11 is provided on the second hook-shaped part 9. This design enables the equipment to firmly hold the I-beam, greatly reducing the risk of the I-beam slipping during the hoisting process, bringing significant safety protection to the construction site. Whether during hoisting or transportation, it can ensure that the I-beam is stably fixed on the equipment, avoiding accidents, and effectively protecting the lives of construction workers and the property safety at the construction site.

[0069] In terms of efficiency:

[0070] The application of the core secondary electric telescopic rod 14 brings an efficient operation experience to the equipment. It makes the clamping and releasing of the I-beam extremely simple and fast, without the need to spend a lot of time for manual adjustment. The operator only needs to issue an instruction through the controller, and the electric telescopic rod can quickly respond and complete the corresponding action. This greatly shortens the hoisting preparation and unloading time, makes the overall process of steel structure construction smoother, greatly improves the construction efficiency, and provides strong support for the smooth progress of the project.

[0071] In terms of operational simplicity:

[0072] The controller 16 of the device can be connected to an external control terminal, thus enabling remote control. This means that the operator can easily complete the clamping and releasing operations of the I-beam without directly contacting the device. This remote control method not only simplifies the operation process and reduces the operation difficulty, but also provides a safer and more convenient working environment for construction workers. At the same time, remote control also improves the flexibility and convenience of construction. The operator can operate the device at a safer location and better control the construction progress.

[0073] In terms of adaptability:

[0074] The device is highly flexible in design and can be applied to I-beams of various sizes and shapes. Regardless of how the specifications of the I-beam change, the device can effectively clamp the I-beam by adjusting the positions of the hook-shaped plate body and the electric telescopic rod. In addition, the device can also adapt to different construction environments and requirements. Whether in a narrow space or a complex construction site, it can play a good role. This strong adaptability improves the versatility and practicality of the device and brings more convenience to steel structure construction.

[0075] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
