AI Technical Summary
In existing steel pipe hoisting devices, the clamps make smooth contact with the surface of the steel pipe, which makes the steel pipe prone to slipping when hoisting or turning in the air. The probability of slipping increases especially in rainy weather or when there is oil, posing a safety risk.
The design employs a first and second fixed ring, with a rubber layer inside the ring. The sliding plate and sliding block are driven by an electric push rod to ensure that the fixed ring fits tightly with the steel pipe, increasing friction. Combined with pulleys and wear-resistant rings, this improves sliding stability.
It effectively prevents the steel pipe from slipping between the fixing rings, improves hoisting safety, reduces hook wear, and enhances the fixing effect.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe hoisting technology, and specifically to a steel pipe hoisting and fixing device. Background Technology
[0002] Steel pipes are hollow, long steel materials, widely used as pipelines for transporting fluids such as oil, natural gas, water, coal gas, and steam. In addition, they are lighter in weight while maintaining the same bending and torsional strength, so they are also widely used in the manufacture of mechanical parts and engineering structures. During engineering construction, steel pipes need to be hoisted.
[0003] For example, Chinese patent CN219971608U discloses a steel pipe hoisting and fixing device for construction. This patent uses a second motor to drive a worm gear, which, in conjunction with a worm wheel and connecting shaft, drives a steering shaft to rotate. This allows for horizontal adjustment of the hoisted steel pipe, facilitating workers to place the pipe at the required position at high altitudes and improving the device's applicability. A spacing adjustment mechanism allows for adjusting the distance between two fixing boxes, which, in conjunction with a clamping and fixing mechanism, can clamp and fix steel pipes of different lengths, making the device suitable for various pipe lengths. However, in this design, because the clamps are in direct contact with the steel pipe, and both the inner wall of the clamps and the surface of the steel pipe are smooth, the steel pipe is prone to slipping between the clamps due to inertia during hoisting or aerial turning. This is especially problematic in rainy weather or when the steel pipe surface is oily, increasing the probability of slippage and posing a certain risk. Utility Model Content

This is especially true in rainy weather or when the surface of the steel pipe is oily, which increases the probability of the steel pipe slipping and causes certain risks.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A steel pipe hoisting and fixing device includes: a connecting plate, on both sides of which connecting blocks are fixedly installed, and a second mounting block is fixedly installed on the bottom surface of the connecting blocks; and a fixing component, which is disposed on the bottom surface of the second mounting block and used to fix the steel pipe during hoisting.

[0009] To reduce wear on the hook, as a steel pipe hoisting and fixing device of this utility model, preferably, a wear-resistant ring is fixedly sleeved on the inner circular wall of the hook.
[0010] In order to improve the anti-slip properties of the steel pipe within the first and second fixing rings, as a steel pipe hoisting and fixing device of this utility model, preferably, the inner circular wall surface of the rubber layer is provided with several grooves.

At this point, the steel pipe is fixed between the first and second fixing rings, and the rubber layer inside the first and second fixing rings is tightly attached to the outer wall of the steel pipe, increasing the friction between them. During hoisting, the steel pipe is less likely to slide between the first and second fixing rings, improving the safety of hoisting the fixed steel pipe. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A steel pipe hoisting and fixing device includes a connecting plate 1, with connecting blocks 2 fixedly installed on both sides of the connecting plate 1, and a second mounting block 7 fixedly installed on the bottom surface of the connecting blocks 2; a fixing assembly, disposed on the bottom surface of the second mounting block 7, for fixing the steel pipe during hoisting, the fixing assembly includes a first fixing ring 8, the first fixing ring 8 fixedly installed on the bottom surface of the second mounting block 7, and a second movable opening 14 opened on the bottom surface of the second mounting block 7, with a sliding block 11 movably sleeved inside the second movable opening 14. A fixing block 10 is fixedly installed on the bottom surface of the connecting plate 1. A second fixing ring 9 is fixedly installed on the bottom surface of the fixing block 10. A first movable opening 13 is opened on one side of the second mounting block 7. The first movable opening 13 and the second movable opening 14 are internally connected. A sliding plate 12 is fixedly installed between the two sliding blocks 11. The sliding plate 12 is movably sleeved with the first movable opening 13. A rubber layer 22 is fixedly sleeved on the inner circular wall of the first fixing ring 8 and the second fixing ring 9 respectively. An installation opening 18 is opened on one side of the connecting plate 1. An electric push is fixedly sleeved inside the installation opening 18. A mounting plate 20 is fixedly installed on the top surface of the rod 19 and the sliding plate 12. By setting a second fixing ring 9, when hoisting the steel pipe, the first fixing ring 8 and the second fixing ring 9 are first moved to the side of the steel pipe, so that the steel pipe is located between the first fixing ring 8 and the second fixing ring 9. Then, the electric push rod 19 in the mounting port 18 can be activated, so that the telescopic shaft of the electric push rod 19 moves the mounting plate 20 to the side of the connecting plate 1. At the same time, the sliding plate 12 moves inward inside the first movable port 13. The sliding plate 12 is connected to the sliding block 11 by the fixing block 10. The second fixing ring 9 then begins to move towards the steel pipe until it is in contact with the outer wall of the steel pipe. At this point, the steel pipe is fixed between the first fixing ring 8 and the second fixing ring 9. After the steel pipe is fixed between the first fixing ring 8 and the second fixing ring 9, the rubber layer 22 inside the first fixing ring 8 and the second fixing ring 9 is tightly attached to the outer wall of the steel pipe, increasing the friction between them. This makes it less likely for the steel pipe to slide between the first fixing ring 8 and the second fixing ring 9 during hoisting, thus improving the safety of hoisting the fixed steel pipe.
[0025] Example 2
[0026] Based on the above embodiment 1, refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A U-shaped plate 15 is fixedly installed on one side of the second mounting block 7, and a pulley 17 is fixedly installed on one side of the sliding block 11. A sliding opening 16 is provided on one side of the second mounting block 7, which communicates with the interior of the second movable opening 14. The sliding opening 16 is movably connected to the pulley 17. By setting the pulley 17, when the sliding block 11 in the sliding opening 16 is moved, the pulley 17 can slide on one side of the U-shaped plate 15, thereby improving the smoothness of the sliding block 11 sliding in the sliding opening 16. A bracket 3 is fixedly installed on the top surface of the connecting block 2. A first mounting block 4 is fixedly installed on the side of the two brackets 3 that are close to each other. A hook 5 is fixedly installed on the top surface of the first mounting block 4. By setting the hook 5, after the steel pipe is fixed between the first fixing ring 8 and the second fixing ring 9, the fixed steel pipe can be lifted by the hook 5. Wear-resistant rings 6 are fixedly fitted onto the inner circular wall of the mounting plate 20. By setting wear-resistant rings 6, the wear resistance of the hook 5 can be improved and the wear of the hook 5 can be reduced when the steel pipe is hoisted by the hook 5. Several grooves 23 are opened on the inner circular wall of the rubber layer 22. By setting grooves 23, the grooves 23 further improve the anti-slip properties of the steel pipe in the first fixed ring 8 and the second fixed ring 9. The top and bottom surfaces of the sliding plate 12 are respectively in contact with the inner top and bottom surfaces of the first movable opening 13 to prevent the sliding plate 12 from shaking inside the first movable opening 13 when the second fixed ring 9 is moved to fix the steel pipe, which would affect the fixing effect of the steel pipe. An installation ring 21 is fixedly installed on one side of the mounting plate 20. The outer circular wall of the telescopic shaft of the electric push rod 19 is fixedly fitted onto the inner circular wall of the installation ring 21 for easy fixing to the mounting plate 20.
[0027] Working principle: Please refer to Figures 1-6As shown, by setting a second fixing ring 9, when hoisting the steel pipe, the first fixing ring 8 and the second fixing ring 9 are first moved to the side of the steel pipe, so that the steel pipe is located between the first fixing ring 8 and the second fixing ring 9. Then, the electric push rod 19 in the mounting port 18 can be activated, so that the telescopic shaft of the electric push rod 19 moves the mounting plate 20 to the side of the connecting plate 1. At the same time, the sliding plate 12 moves inward inside the first movable port 13. The second fixing ring 9, which is connected to the sliding plate 12 through the fixing block 10 and the sliding block 11, begins to move to the side of the steel pipe until the second fixing ring 9 is in contact with the outer wall of the steel pipe. At this time, the steel pipe is fixed between the first fixing ring 8 and the second fixing ring 9. After the steel pipe is fixed between the first fixing ring 8 and the second fixing ring 9, the rubber layer 22 inside the first fixing ring 8 and the second fixing ring 9 is tightly in contact with the outer wall of the steel pipe, increasing the friction between them. During hoisting, the steel pipe is less likely to slide between the first fixing ring 8 and the second fixing ring 9, thus improving the safety of hoisting the fixed steel pipe.
