Description

Technical Field

[0001] This utility model relates to the field of traction support technology, and in particular to a safety device for attaching safety belts when unloading mixed tower ring plates. Background Technology

[0002] The rise of hybrid tower construction technology is an inevitable choice for the wind power industry to cope with challenges such as increased height, cost pressure, and environmental adaptability. Through innovations such as complementary material properties, modular design, and intelligent production, it achieves a balance between economy, safety, and adaptability. With the improvement of the standard system and the continuous iteration of technology, hybrid towers will become the mainstream form of wind power towers in the future, driving the industry towards higher efficiency and lower cost.

[0003] Existing technologies often have the following drawbacks: mixed tower installation includes segmented splicing and hoisting as well as whole-ring hoisting. Since the pre-embedded holes of the hoisting rings are located on the top surface of the mixed tower segments and the height of the mixed tower segments is greater than 2m, workers need to climb onto the tower segments to move and carry out construction. However, there are no suitable hanging points on the mixed tower segments. Generally, safety belts are hung on hand-operated hoists, but this method is cumbersome and inconvenient to move, which can easily affect construction.

[0004] Therefore, this utility model provides a safety device for attaching safety belts when unloading mixed tower ring plates. Utility Model Content

[0005] The purpose of this application is to better address the installation of lifting equipment for unloading mixed tower sections, and to better ensure the safety of workers moving and working on the mixed tower sections. Therefore, a safety device for attaching safety belts for unloading mixed tower sections is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a safety device for securing a safety belt during unloading of mixed tower ring plates, comprising a left steel component and a right steel component. The left steel component has two sliding plates internally connected, and a first horizontal plate is fixedly connected to the ends of the two sliding plates. The right steel component has a second horizontal plate internally connected, and a safety belt attachment point steel component is fixedly connected to the upper side of the first horizontal plate.

[0007] The effect achieved by the above components is that after relocking, the safety belt can be fastened in the new position. The whole process does not require the use of a hand-operated hoist. The operation is easy and flexible, which not only ensures the safety of workers during mobile operations, but also greatly improves construction efficiency.

[0008] Preferably, a support rod is fixedly connected to the surface of the first horizontal plate, and an insert rod is slidably connected inside the support rod. A plurality of slots are provided on the surface of the second horizontal plate, and the size of the insert rod is adapted to the size of the slot.

[0009] The effect achieved by the above components is to push the slidingly connected insert rod inside the support rod, so that it is inserted into the corresponding slot opened on the surface of the second horizontal plate.

[0010] Preferably, the left steel member is internally threaded with a drive rod, and the drive rod is internally rotatably connected to the first horizontal plate.

[0011] The effect achieved by the above components is that the drive rod connected to the internal thread of the rotating left steel component can be converted into the linear movement of the first horizontal plate along the length of the left steel component because the drive rod is rotatably connected to the first horizontal plate and the first horizontal plate is slidably engaged with the left steel component through the sliding plate.

[0012] Preferably, a stop is fixedly connected to the side wall of the insertion rod.

[0013] The effect achieved by the above components is that the stop prevents the insert rod from slipping out of the support rod.

[0014] Preferably, the surface of the insertion rod is fitted with a spring, and the two ends of the spring are fixedly connected to the stop block and the support rod, respectively.

[0015] The effect achieved by the above components is that the two ends of the spring sleeved on the surface of the insertion rod are fixedly connected to the stop block and the support rod respectively, and the spring will generate an elastic thrust on the stop block in its natural state.

[0016] Preferably, the surfaces of both the left and right steel components are bonded with anti-slip pads.

[0017] The effect achieved by the above components is that the anti-slip pads bonded to the surfaces of the left and right steel components are in close contact with the building surface, thereby increasing friction and preventing the device from sliding or shifting during operation.

[0018] In summary: In contrast to the previous lack of suitable safety anchor points, the safety device of this application can be installed as needed and its size can be adjusted to suit mixed tower plates of different thicknesses, greatly improving safety assurance. Compared to the previous method of hanging on a hand chain hoist, which was cumbersome to operate and inconvenient to move, the safety device of this application is lightweight and can be moved and installed in different positions as needed, greatly improving construction efficiency.

[0021] Reference Figure 1-4 As shown, this utility model provides a technical solution: a safety device for attaching a safety belt for unloading mixed tower ring plates, comprising a left steel component 1 and a right steel component 2.

[0022] The following is a detailed explanation of its overall setup and function.

[0023] In this implementation scheme: The left steel component 1 has two sliding plates 12 internally connected, and a first horizontal plate 3 is fixedly connected to the ends of the two sliding plates 12. The right steel component 2 has a second horizontal plate 4 internally connected, and a safety belt attachment point steel component 5 is fixedly connected to the upper side of the first horizontal plate 3. After relocking, the safety belt can be fastened in the new position. The entire process does not require a hand-operated hoist, making operation convenient and flexible, ensuring worker safety during movement and significantly improving construction efficiency. A support rod 6 is fixedly connected to the surface of the first horizontal plate 3, and an insert rod 7 is slidably connected internally to the support rod 6. Several slots 8 are provided on the surface of the second horizontal plate 4, and the size of the insert rod 7 matches the size of the slots 8. Pushing the insert rod 7 internally connected to the support rod 6 allows it to insert into the corresponding slot 8 on the surface of the second horizontal plate 4. A drive rod 13 is threadedly connected internally to the left steel component 1, and the drive rod 13 is rotatably connected to the interior of the first horizontal plate 3. The drive rod 13, internally threaded to the left steel component 1, is rotatably connected to the first horizontal plate 3. Since the first horizontal plate 3 is slidably engaged with the left steel component 1 via the sliding plate 12, the rotational motion of the drive rod 13 can be converted into linear movement of the first horizontal plate 3 along the length of the left steel component 1. A stop block 9 is fixedly connected to the side wall of the insertion rod 7. The stop block 9 prevents the insertion rod 7 from slipping out of the support rod 6. A spring 10 is fitted onto the surface of the insertion rod 7, with both ends of the spring 10 fixedly connected to the stop block 9 and the support rod 6, respectively. In its natural state, the spring 10 exerts an elastic thrust on the stop block 9.

[0024] Specifically, anti-slip pads 11 are glued to the surfaces of both the left steel component 1 and the right steel component 2. The anti-slip pads 11 glued to the surfaces of the left steel component 1 and the right steel component 2 are in close contact with the building surface, increasing friction to prevent the device from sliding or shifting during operation.

[0025] Working principle: Spacing locking and structural reinforcement. After adjusting the spacing between the left and right steel components 2, push the slidingly connected insert rod 7 inside the support rod 6 to insert it into the corresponding slot 8 on the surface of the second horizontal plate 4. Since the side wall of the insert rod 7 is fixedly connected to the stop block 9, and the two ends of the spring 10 sleeved on the surface of the insert rod 7 are fixedly connected to the stop block 9 and the support rod 6 respectively, the spring 10 will generate an elastic thrust on the stop block 9 in its natural state, causing the insert rod 7 to remain inserted into the slot 8, thereby locking the relative position of the first horizontal plate 3 and the second horizontal plate 4, further reinforcing the clamping structure of the left and right steel components 2 and the mixing tower ring plate, preventing the spacing from loosening when the device is moved by the worker. Then, rotate the drive rod 13, which is threaded inside the left steel component 1. Since the drive rod 13 is rotatably connected to the first horizontal plate 3, and the first horizontal plate 3 is slidably engaged with the left steel component 1 through the sliding plate 12, the rotational movement of the drive rod 13 can be converted into a linear movement of the first horizontal plate 3 along the length direction of the left steel component 1, thereby adjusting the spacing between the left steel component 1 and the right steel component 2. The spacing is adjusted to fit the thickness of the mixing tower ring. Then, the left steel component 1 and the right steel component 2 are respectively attached to the two sides of the building. At this time, the anti-slip pads 11 glued to the surface of the left steel component 1 and the right steel component 2 are in close contact with the building surface. By increasing the friction, the device is prevented from sliding or shifting during operation, thus achieving stable clamping of the device. After the safety belt fastening and movement adapter is fixed, the worker can directly fasten the safety belt to the safety belt hanging point steel component 5. This hanging point is a specially designed load-bearing structure that can stably withstand the pulling force of the worker during operation, solving the problem of traditional lack of suitable hanging points. When the worker needs to work at different positions on the mixing tower ring, the locking of the insertion rod 7 and the slot 8 can be released, the insertion rod 7 can be pulled outward to compress the spring 10, so that the insertion rod 7 is disengaged from the slot 8. Then, the position of the device can be adjusted by the drive rod 13, and after relocking, the safety belt can be fastened at the new position. The whole process does not rely on the hand hoist, the operation is easy and the movement is flexible, which not only ensures the safety of the worker's movement operation, but also greatly improves the construction efficiency.
