Description

[0002] As a common pipe material, galvanized pipe has the characteristics of large volume and relatively light weight, and the bound shape is a regular hexagon. In the portal crane hoisting operation, usually a group of galvanized pipes is hoisted as a sling, and 5-6 pieces of galvanized pipes are hoisted at a time. When multiple galvanized pipes are hoisted by sling, the contact area between the sling and the lower galvanized pipe is relatively small, resulting in a relatively large pressure on the unit area. Under the action of gravity and the sway during hoisting, this concentrated pressure is easy to cause local indentation or distortion of the thin-walled galvanized pipe. In addition, the traditional hoisting method may not evenly distribute the hoisting force, so that some parts of the galvanized pipe bear too much load, thereby increasing the risk of deformation. In summary, due to the characteristics of the thin-walled galvanized pipe itself and the defects of the traditional hoisting method, the goods in contact with the sling on the lower side are prone to deformation during hoisting, which not only affects the quality of the goods, but also brings certain difficulties to the loading and unloading operation. Therefore, a new type of sling is needed to improve the single hoisting operation capacity, reduce the pressure of the sling on the galvanized pipe, avoid damage to the galvanized pipe, and realize the double improvement of freight quality and loading and unloading rate.

[0037] Embodiment 1

[0038] Reference Figures 1-3 For the first embodiment of the present application, a galvanized pipe lifting device is proposed for lifting a galvanized pipe stack, which comprises a first supporting cable 1, the first supporting cable 1 is used to abut with the bottom wall of the galvanized pipe stack; the pressure lever 2 abuts with the top wall of the galvanized pipe stack, and the two ends of the first supporting cable 1 are arranged at the two ends of the pressure lever 2.

[0039] In this embodiment, when performing hoisting operation, the first supporting cable 1 is placed at the bottom of the galvanized pipe stack and fully contacts with the bottom wall. Then, the pressing lever 2 is pressed on the top of the galvanized pipe stack, and the pressing lever 2 supports the two ends of the first supporting cable 1 to ensure that the first supporting cable 1 contacts with the galvanized pipe stack more uniformly and does not cause excessive extrusion to the galvanized pipes on both sides of the bottom. The pressing lever 2 supports the two ends of the first supporting cable 1 to increase the contact area of the first supporting cable 1 with the galvanized pipe stack, disperses the pressure, and effectively avoids the deformation of the galvanized pipes on both sides of the bottom caused by concentrated extrusion. It ensures that the galvanized pipe stack is uniformly stressed during hoisting, reduces shaking and displacement, reduces the risk of deformation, and protects the integrity of the goods. At the same time, the pressing lever 2 can also abut and extrude the top wall of the galvanized pipe stack. The simple and effective structure design not only meets the needs of preventing extrusion deformation, but also facilitates operation and installation, and improves the efficiency of hoisting operation. Reducing the deformation of galvanized pipes caused by hoisting, reducing the damage rate, ensuring the quality of goods, and improving the safety of transportation and storage.

[0040] Further, the hoisting beam 3 is located above the galvanized pipe stack; the first connecting cable 4 is arranged in pairs, one end of the two first connecting cables 4 is arranged on the hoisting beam 3, and the other end is arranged at the two ends of the pressing lever 2, respectively.

[0041] In this embodiment, when performing hoisting operation, the first connecting cable 4 connects the pressing lever 2 with the hoisting beam 3 located above the galvanized pipe stack. The lifting device is connected with the hoisting beam 3, and the whole lifting appliance and the galvanized pipe stack are hoisted through the hoisting beam 3. The hoisting beam 3 provides a unified hoisting position, which is convenient for the connection and operation of the lifting device, and makes the hoisting process more standardized and efficient. Through the connection of the first connecting cable 4 and the pressing lever 2, the structural stability of the whole lifting appliance is enhanced, and the shaking and deformation risk in the hoisting process is reduced.

[0042] Further, the connecting cable member 5 is arranged on the hoisting beam 3; the hook member 6 is swingably arranged at one end of the connecting cable member 5, the hook member 6 has a hook portion 601, and the connecting cable member 5 and the hook member 6 are arranged in pairs; the second supporting cable 7 is located on one side of the first supporting cable 1, and the second supporting cable 7 is used to abut with the bottom wall and the side wall of the galvanized pipe stack, and the two ends of the second supporting cable 7 are respectively sleeved on the two hook portions 601.

[0043] In the embodiment, before the hoisting operation is performed, the two ends of the second supporting cable 7 are sleeved on the two hook parts 601. Then, by adjusting the positions of the connecting cable 5 and the hook part 6, the second supporting cable 7 is tightly abutted against the bottom wall and the side wall of the galvanized pipe stack. When hoisting, the whole lifting tool and the galvanized pipe stack are lifted by the lifting beam 3. The second supporting cable 7 is abutted against the bottom wall and the side wall of the galvanized pipe stack, the area of support is increased, the pressure is further dispersed, and the possibility of deformation is reduced. The combination of the pair of connecting cable 5, hook part 6 and second supporting cable 7 can fix the galvanized pipe stack from more directions, and the stability during hoisting is improved. The first supporting cable 1 mainly abuts against the bottom wall of the galvanized pipe stack and bears most of the vertical pressure. The second supporting cable 7 is on one side of the first supporting cable 1 and abuts against the bottom wall and the side wall. The two cooperate with each other to support the galvanized pipe stack from different positions and angles, so that the galvanized pipe stack can be effectively supported in the bottom wall and side wall directions, the stress is dispersed, and the risk of deformation of the galvanized pipe during hoisting is further reduced.

[0044] Further, the hook part 6 also has a counterweight end 602, the hook part 601 and the counterweight end 602 are respectively located at two ends of the hook part 6, and the hook part 6 is configured to be oscillated to sleeve or separate the two ends of the second supporting cable 7.

[0045] In the embodiment, during hoisting, the hook part 601 sleeves the two ends of the second supporting cable 7 to support the galvanized pipe stack. When hoisting is completed and the galvanized pipe stack is placed in place, the hook part 601 is no longer stressed, at this time the counterweight end 602 automatically falls due to gravity, drives the hook part 6 to oscillate, so that the hook part 601 automatically separates from the second supporting cable 7, and unhooking is realized. Through the cooperation of the hook part 601 and the counterweight end 602, automatic unhooking after hoisting is realized, manual operation is reduced, and work efficiency is improved. Since it is automatic unhooking based on the stress state, unhooking can be accurately realized at the right time, and problems caused by premature or late unhooking are avoided.

[0046] Embodiment 2

[0047] Reference Figures 4-5 For the second embodiment of the utility model, which is different from the first embodiment:

[0048] Compared with the first embodiment, further, the two ends of the compression lever 2 have a guide sliding groove 201 in the length direction, and further comprising a sliding block 8, the sliding block 8 is slidingly arranged in the guide sliding groove 201, the sliding block 8 has a first fixed part 801 and a second fixed part 802, the first fixed part 801 and the second fixed part 802 are arranged adjacent in the height direction of the compression lever 2, the two ends of the first supporting cable 1 are arranged on the first fixed part 801, and one end of the first connecting cable 4 is arranged on the second fixed part 802.

[0049] In this embodiment, during hoisting operation, as the lifting proceeds, the sliding blocks 8 will slide towards each other. Since the two ends of the first supporting cable 1 and one end of the first connecting cable 4 are fixed on different fixed parts of the sliding blocks 8, the sliding of the sliding blocks 8 will cause the two ends of the first connecting cable 4 to slide towards each other, thereby further compressing the galvanized pipe pile laterally. This action is particularly suitable for situations where the preset length of the galvanized pipe pile and the first connecting cable does not match, or in a shaking work environment. Through the sliding adjustment of the sliding blocks 8, the problem of length mismatch can be compensated in time, and in a shaking environment, the lateral compression force on the galvanized pipe pile is enhanced, reducing the possibility of shaking and displacement. It can effectively deal with the problem of mismatch between the preset length of the galvanized pipe pile and the first connecting cable, ensuring the smooth progress of hoisting. In a shaking work environment, the sliding compression of the sliding blocks 8 improves the stability of the entire hoisting structure, reducing the shaking and displacement of the galvanized pipe pile. Reducing the risk of accidents caused by length mismatch or shaking, ensuring the safety of the operation. The lifting device can adapt to more different working conditions and cargo situations, improving its versatility and practicality.

[0050] Further, the first fixed part 801 and the second fixed part 802 are arranged along the length direction of the pressing rod 2.

[0051] In this embodiment, during preparation for hoisting, first, according to the approximate size and shape of the galvanized pipe pile, select appropriate positions from the multiple first fixed parts 801 and second fixed parts 802 for preliminary fixing, complete the basic adjustment. Then, through the sliding of the sliding block 8 in the guide sliding groove 201, the position of the first supporting cable 1 and the first connecting cable 4 is coarsely adjusted. When adjusted to the appropriate position, the sliding block 8 is fixed by using the relevant locking device, realizing precise adjustment and locking. The combination of basic adjustment and coarse adjustment of the sliding block provides a more comprehensive and accurate position adjustment method, ensuring that the lifting device perfectly matches the galvanized pipe pile. It can adapt to galvanized pipe piles of various specifications, shapes and placement states, greatly improving the adaptability of the lifting device. More accurate position adjustment helps to further optimize the stress distribution of the first supporting cable 1 and the first connecting cable 4, effectively reducing the deformation of the galvanized pipe.

[0052] Further, it also includes a first elastic member 9, one end of the first elastic member 9 acting on the bottom wall of the guide sliding groove 201. The other end provides a force acting on the sliding block 8, providing a force for the sliding block 8 to reset away from the bottom wall of the guide sliding groove 201.

[0053] In the embodiment, during the hoisting process, when the sliding blocks 8 slide close to each other, the first elastic members 9 are compressed to accumulate elastic potential energy. When the hoisting is completed and the external force disappears, the first elastic members 9 release the elastic potential energy to push the sliding blocks 8 to reset, so that they are away from the bottom wall of the guide sliding groove 201 and return to the initial position. The first elastic members 9 can automatically reset the sliding blocks 8 after the hoisting is completed, facilitating the next hoisting operation and improving the work efficiency. Manual resetting of the sliding blocks 8 is not required, simplifying the operation process. The stable resetting function ensures the consistency of the initial state of the lifting appliance each time it is used, improving the reliability and stability of the lifting appliance.

[0054] Further, the bottom wall of the guide sliding groove 201 has a receiving groove 202, and the first elastic members 9 are configured to enter the receiving groove 202 after compression or leave the receiving groove 202 after decompression.

[0055] In the embodiment, during the hoisting process, the sliding blocks 8 slide close to each other, compressing the first elastic members 9 and causing the first elastic members 9 to enter the receiving groove 202. When the hoisting is completed and the external force disappears, the first elastic members 9 return to their original state, leaving the receiving groove 202 and pushing the sliding blocks 8 to reset. The receiving groove 202 provides storage space for the compressed first elastic members 9, making the structure more compact and avoiding the occupation of too much space by the first elastic members 9 when they are compressed, which affects the sliding of the sliding blocks 8. The receiving groove 202 provides protection for the first elastic members 9, reducing external interference and damage during operation.

[0056] Further, the connecting cable member 5 has a steel chain part 501 and a connecting shell part 502, and the hook member 6 is swingably arranged on the connecting shell part 502.

[0057] In the embodiment, during the hoisting operation, the steel chain part 501 transmits the tension from the hoisting beam 3 to the connecting shell part 502. The hook member 6 can freely swing on the connecting shell part 502 to adapt to different hoisting angles and position requirements. The steel chain part 501 ensures the strength and stability of the connection, and the connecting shell part 502 and the swingable hook member 6 increase the flexibility and adaptability of the lifting appliance. Reasonable structural design helps to disperse the stress generated during hoisting, reducing the damage to components and deformation of galvanized pipes caused by excessive local stress.

[0058] Further, the top of the hoisting beam 3 has a total hoisting hole 301.

[0059] In the embodiment, during the hoisting operation, the hook or other hoisting connecting member of the hoisting equipment is connected to the hoisting beam 3 through the total hoisting hole 301, thereby realizing the lifting operation of the entire lifting appliance and the galvanized pipe stack. The total hoisting hole 301 provides a clear and concentrated hoisting connection point, ensuring that the lifting force can be evenly applied to the hoisting beam 3 and then transmitted to the entire lifting appliance and the galvanized pipe stack, reducing deformation caused by uneven stress.
