Description

Technical Field

[0001] The utility model relates to the field of boiler hoisting, and specifically relates to a hoisting and transferring device for a tank body. Background Technique

[0002] The hoisting and transferring device for the tank body is a key device in the boiler installation process. It is usually composed of a hoisting device, a hoisting and transferring frame device, etc., and has the characteristics of high efficiency, safety, convenience, etc. These devices adopt advanced hoisting technologies and stable structural designs, and can quickly and accurately hoist boiler components to the designated positions, improve the installation efficiency, and ensure the stability and safety during the hoisting and transferring processes.

[0003] The existing hoisting and transferring device for the tank body can quickly and accurately hoist boiler components to the designated positions. When hoisting and transferring the components on the boiler, generally two steel wires are connected to the hook on the overhead crane, and most of the two steel wires are on both sides of the center point of the boiler component. When the boiler component moves upward, the boiler component will shake when rising, and may cause the boiler component to skew, which may not only pose potential safety hazards to the boiler itself and its surrounding equipment, but also reduce the use safety of the hoisting and transferring device for the boiler component. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a hoisting and transferring device for a tank body to solve the technical problem that the boiler component may skew when shaking during rising, which may pose potential safety hazards to the boiler itself and its surrounding equipment.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A hoisting and transferring device for a tank body, including a tank body, two groups of mounting seats are arranged on the top of the tank body, hanging holes are opened on the surfaces of the mounting seats, hooks are penetrated inside the hanging holes, steel wires are arranged on the tops of the hooks, mounting blocks are sleeved on the surfaces of the steel wires, first screws and second screws are arranged on the outer sides of the mounting blocks, threaded sleeves are threadedly connected to the surfaces of the first screws and the second screws, and abutting blocks are arranged at the bottoms of the second screws.

[0006] By adopting the above technical solution, when the boiler component needs to be hoisted and transferred, the operator will accurately hang the hook in the hanging hole of the mounting seat on the top of the tank body, and this operation realizes the firm connection between the tank body and the steel wire, providing reliable support for the subsequent hoisting work.

[0007] Further, two groups of the first screws, the second screws, the threaded sleeves and the abutting blocks are provided, and are arranged in a mirror image.

[0008] By adopting the above technical solution, the hoisting and transferring device can provide uniform support and abutting force on both sides of the tank body, thus ensuring the balance of the tank body during hoisting.

[0009] Furthermore, the whole of the abutting block is of an arc-shaped structure, and its bottom abuts against the tank body to increase the abutting area.

[0010] By adopting the above technical solution, the pressure generated during hoisting can be effectively dispersed, avoiding the deformation or damage of the tank body caused by excessive local pressure.

[0011] Furthermore, the bottom of the tank body is provided with two groups of bases. One side of each base is of an arc-shaped structure and is used to adapt to the structure of the tank body.

[0012] By adopting the above technical solution, when the tank body needs to be placed or transported, the bases can effectively disperse its weight, preventing deformation or damage caused by excessive single-point stress.

[0013] Furthermore, the surface of the threaded sleeve is provided with a pattern layer to increase the friction between the threaded sleeve and the operator's hand.

[0014] By adopting the above technical solution, the friction between the threaded sleeve and the hand can be effectively increased. This increased friction enables the operator to more easily turn the threaded sleeve, and the precise adjustment of the screw rod length can be achieved without excessive force, which not only improves the work efficiency but also reduces the physical burden on the operator.

[0015] Furthermore, there are two but not limited to two forms of the included angle between the first screw rod and the mounting block.

[0016] By adopting the above technical solution, in practical applications, due to the different shapes, sizes of boiler components and hoisting environments, different included angles may be required to adapt to these changes. By providing multiple included angles, the hoisting and transferring device can more accurately match the actual needs of boiler components, improving its adaptability and practicability.

[0017] Furthermore, the other end of the steel wire rope is connected to an external transferring device.

[0018] By adopting the above technical solution, it can be ensured that the boiler component always remains stable during hoisting, avoiding shaking or falling caused by unstable connection, thus improving the hoisting efficiency.

[0019] In summary, the main beneficial effects of the present utility model are as follows:

[0020] 1. Through the first screw, the second screw, the threaded sleeve and the abutting block, when the boiler component needs to be transported, the operator hangs the hook in the hanging hole of the mounting seat preset on the top of the tank body. In this way, a reliable connection is formed between the tank body and the steel wire rope, laying a solid foundation for the subsequent hoisting and transfer work. At the same time, in order to further enhance the stability during hoisting, the operator turns the threaded sleeves equipped on both sides of the mounting block. By adjusting the threaded sleeves, the lengths of the first screw and the second screw connected thereto can be changed until the abutting block at the end of the second screw tightly abuts against the tank body. The abutting block not only increases the contact area with the tank body, but also effectively reduces the possible shaking of the boiler component during hoisting, thus avoiding the occurrence of unsafe situations such as the skew of the boiler component. This not only reduces the potential safety hazards caused by the shaking of the boiler component to the boiler itself and its surrounding equipment, but also greatly improves the use safety of the hoisting and transfer device of the tank body, ensuring the smooth and successful progress of the entire hoisting process;

[0021] 2. By setting the pattern layer, the roughness of the surface of the threaded sleeve is increased, directly enhancing the friction between the operator's hand and the threaded sleeve. When turning the threaded sleeve to adjust the lengths of the first screw and the second screw, the increased friction makes the operation more convenient, reducing the need for repeated operations due to hand slippage, thereby improving work efficiency. At the same time, the design of the pattern layer also fully considers the variability of the operating environment. In a wet, greasy or dirty working environment, a smooth surface is likely to cause hand slippage, increasing the operation difficulty and safety hazards. However, the additional friction provided by the pattern layer can still maintain a firm grip of the threaded sleeve by the operator under these adverse conditions, effectively preventing the occurrence of slippage accidents and ensuring the safety of the operator and the smooth progress of the hoisting operation.

[0029] The following describes the embodiments according to the overall structure of the present utility model. Embodiment 1:

[0030] A hoisting and transferring device for a tank body, as Figures 1 - 3As shown in the figure, it includes a tank body 1. Two groups of mounting seats 5 are arranged at the top of the tank body 1. Hanging holes 12 are opened on the surface of the mounting seats 5. A hook 4 is arranged through the inside of the hanging holes 12. A steel wire rope 3 is arranged at the top of the hook 4. A mounting block 11 is sleeved on the surface of the steel wire rope 3. A first screw rod 6 and a second screw rod 7 are arranged on the outside of the mounting block 11. Threaded sleeves 8 are threadedly connected to the surfaces of the first screw rod 6 and the second screw rod 7. An abutting block 10 is arranged at the bottom of the second screw rod 7. When the boiler component needs to be hoisted and transported, the operator will accurately hang the hook 4 in the hanging hole 12 of the mounting seat 5 at the top of the tank body 1. This operation realizes the stable connection between the tank body 1 and the steel wire rope 3, providing a reliable support for the subsequent hoisting work. At the same time, in order to enhance the stability of the boiler component during hoisting, the operator will turn the threaded sleeves 8 arranged on both sides of the steel wire rope 3. Through the threaded connection method, the lengths of the first screw rod 6 and the second screw rod 7 can be flexibly adjusted. The operator will continuously adjust until the bottom of the abutting block 10 on the second screw rod 7 tightly abuts against the tank body 1. The abutting block 10 not only increases the contact area with the tank body 1 but also effectively reduces the swaying amplitude of the boiler component when moving upward, thus avoiding the occurrence of unsafe situations such as the boiler component tilting during hoisting.

[0031] Refer to Figure 1 , Figure 2 , Figure 3 , the first screw rod 6, the second screw rod 7, the threaded sleeve 8 and the abutting block 10 are all provided with two groups and are arranged in a mirror image. This enables the hoisting and transporting device to provide uniform support and abutting force on both sides of the tank body 1, thus ensuring the balance of the tank body 1 during hoisting. The mirror-image arranged components can correspond to each other and act on the tank body 1 together, avoiding swaying or tilting caused by uneven unilateral force. At the same time, the coordinated work of the two groups of components also enhances the stability and reliability of the hoisting and transporting device. During hoisting, even when encountering external interference or unstable factors, the two groups of mirror-image arranged components can support each other and jointly resist external forces to keep the tank body 1 stable. This not only improves the use safety of the hoisting and transporting device but also ensures that the boiler component can be hoisted to the designated position smoothly and accurately.

[0032] Refer to Figure 1 , Figure 2 , Figure 3, the whole of the abutting block 10 is of an arc-bending structure, and its bottom abuts against the tank body 1, which is used to increase the abutting area, can effectively disperse the pressure generated during the hoisting process, and avoid the deformation or damage of the tank body 1 caused by excessive local pressure. At the same time, the arc-bending structure also increases the contact area between the abutting block 10 and the tank body 1, thereby improving the stability and reliability of the abutment. At the same time, the bottom of the abutting block 10 tightly abuts against the tank body 1, further enhancing the supporting force of the hoisting and transporting device on the tank body 1. During the hoisting process, the abutting block can effectively limit the shaking of the tank body 1 and avoid safety accidents such as the skew or detachment of the boiler components caused by excessive shaking. In addition, the increased abutting area also helps to reduce the friction and wear generated during the hoisting process and extends the service life of the tank body 1 and the hoisting and transporting device.

[0033] Refer to Figure 1 , Figure 2 , a base 2 is provided at the bottom of the tank body 1, and there are two groups. One side of the base 2 is of an arc-bending structure and is used to match the structure of the tank body 1. When the tank body 1 needs to be placed or transported, the base 2 can effectively disperse its weight and prevent deformation or damage caused by excessive single-point stress. At the same time, the cooperative effect of the two groups of bases 2 further enhances the stability of the tank body 1 and ensures that it can remain stable under various working conditions. At the same time, one side of the base 2 is designed as an arc-bending structure, which cleverly matches the structure of the tank body 1. The arc-bending structure can not only better fit the outer shape of the tank body 1, reduce the shaking or gap caused by shape mismatch, but also effectively disperse and bear the pressure from the tank body 1 to protect the tank body 1 from damage. In addition, the arc-bending structure also makes the connection between the base and the tank body closer, improving the overall stability and safety. Embodiment 2:

[0034] Refer to Figure 1 , Figure 2 , Figure 3 , a pattern layer 9 is provided on the surface of the threaded sleeve 8, which is used to increase the friction between the threaded sleeve 8 and the operator's hand. It can effectively increase the friction between the threaded sleeve 8 and the hand. This increased friction enables the operator to more easily turn the threaded sleeve 8, and the precise adjustment of the screw length can be achieved without excessive force, which not only improves the work efficiency but also reduces the physical burden of the operator. At the same time, the pattern layer 9 also takes safety factors into account. In a wet or oily environment, a smooth surface is likely to cause the operator's hand to slip, which may lead to safety accidents. The additional friction provided by the pattern layer can ensure that the operator can firmly hold the threaded sleeve 8 even under adverse conditions, avoiding the risk of slipping, thus ensuring the safety of the operation process.

[0035] Refer to Figure 1 , Figure 2 , Figure 3, there are two but not limited to two forms of the included angle between the first screw rod 6 and the mounting block 11. In actual applications, due to the different shapes, sizes of boiler components and the hoisting environment, different included angles may be required to adapt to these changes. By providing multiple included angles, the hoisting and transfer device can more accurately match the actual needs of boiler components, improving its adaptability and practicability. At the same time, multiple included angles also help to enhance the stability and safety of the hoisting and transfer device. When different included angles are formed between the first screw rod 6 and the mounting block 11, different mechanical effects can be generated, thereby achieving a more stable support and fixation of the boiler component. This stable support not only reduces the shaking and tilting of the boiler component during hoisting, but also reduces the potential safety hazards caused by shaking to the boiler and its surrounding equipment.

[0036] Refer to Figure 1 , Figure 2 , Figure 3 , the other end of the steel wire rope 3 is connected to an external transfer device, which can ensure that the boiler component always remains stable during hoisting, avoiding shaking or falling caused by unstable connection, thereby improving the hoisting efficiency. At the same time, this connection method also enhances the safety of the hoisting and transfer process. As a bridge connecting the boiler component and the external transfer device, the strength and stability of the steel wire rope 3 are directly related to the safety of the entire hoisting process.

[0037] The implementation principle of the present utility model is as follows: When it is necessary to transport the boiler component, first hang the hook 4 on the hanging hole 12 of the mounting seat 5 to achieve the connection between the tank body 1 and the steel wire rope 3. Then, turn the threaded sleeves 8 on both sides of the steel wire rope 3 to change the lengths of the first screw rod 6 and the second screw rod 7 until the bottom of the abutting block 10 on the second screw rod 7 abuts against the tank body 1. Due to the abutment of the abutting block 10 against the tank body 1, the shaking amplitude when the boiler component moves upward is reduced, avoiding the situation of component skew, thereby reducing the possibility of potential safety hazards caused by the shaking of the boiler component during transfer to the boiler itself and its surrounding equipment, and improving the use safety of the hoisting and transfer device of the tank body;

[0038] In some other embodiments, by changing the hook 4 and the steel wire rope 3 into a detachable connection structure, such as threaded connection through a mounting block, different models of hooks 4 and steel wire ropes 3 can be selected for adaptability adjustment according to the mass of the tank body or component itself, improving the applicability to the hoisting environment of the boiler.

[0039] Parts not involved in the present utility model are the same as or can be implemented by the prior art, and will not be elaborated here.

[0040] Although embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and are not limitations thereof. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations that do not contribute creatively to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
