DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0031] Embodiment one: the steel pipe stiffening ring assembling device solves the problem that the steel pipe needs to be welded at different positions after stiffening, the position angle of the steel pipe needs to be adjusted again, and then the steel pipe needs to be welded again, thereby causing inconvenience in welding. The use of the roller 6 can facilitate the splicing of the steel pipe, and the utility model discloses:

[0032] The top of the base 1 is welded with a support 2; the top of the base 1 is rotationally connected with a hydraulic rod 3, the right end of the hydraulic rod 3 is rotationally connected with a connecting plate 4, the left end of the connecting plate 4 is rotationally connected at the top of a supporting rod 5, the bottom of the supporting rod 5 is rotationally connected at the top of the base 1, the inside of the connecting plate 4 is connected with a roller 6 through a bearing, and the outer end of the roller 6 is slidingly connected with a limiting plate 7;

[0033] Reference Figure 1 and Figure 2 , the base 1 is placed on the ground, then the hydraulic rod 3 is controlled to stretch and retract, so that the hydraulic rod 3 can drive the connecting plate 4 to rotate, thereby making the connecting plate 4 rotate with the bottom of the supporting rod 5 as the center, so that the connecting plate 4 can drive the roller 6 to adhere to the outer wall of the steel pipe, thereby playing a role of stiffening, and then the steel pipes can be spliced, thereby facilitating subsequent welding. Then the steel pipe is rotated, so that the steel pipe can be rotated through the roller 6, thereby facilitating the adjustment of the angle of the steel pipe, and thereby facilitating the welding of different positions of the steel pipe, thereby improving the efficiency of welding.

[0034] Embodiment two: the steel pipe stiffening ring assembling device solves the problem that the base 1 is inconvenient to move, the use of the moving roller 12 can facilitate the movement of the base 1, and the utility model discloses:

[0035] The left end of the base 1 is fixed with a motor 8, the right end of the motor 8 extends into the inside of the base 1 and is connected with the left end of a worm 9, the worm 9 is rotationally connected in the inside of the base 1, the rear end of the worm 9 is engaged with a worm wheel 10, the middle part of the worm wheel 10 is keyed in the middle part of an inner rotating rod 11, the top of the inner rotating rod 11 is rotationally connected in the inside of the base 1, the inside of the inner rotating rod 11 is worm-connected with a moving roller 12, and the outer wall of the moving roller 12 is slidingly engaged in the inside of the base 1;

[0036] Reference Figure 1 , Figures 3 to 5When position adjustment is required, the motor 8 drives the worm gear 9 to rotate, which in turn drives the worm wheel 10 to rotate, which in turn drives the inner rotating rod 11 to rotate. The rotation of the inner rotating rod 11 can then drive the transfer roller 12 to move, allowing the transfer roller 12 to slide within the base 1. The base 1 can limit the movement of the transfer roller 12, ensuring that it can only move up and down. The transfer roller 12 can lift the base 1, allowing it to move and thus adjust the position of the base 1. After reaching the desired position, the process is reversed, allowing the transfer roller 12 to be retracted back into the base 1, bringing the base 1 into contact with the ground and facilitating the fixation of its position.

[0037] Example 3: A steel pipe stiffening ring assembly device solves the problem that existing devices cannot limit the movement of different types of steel pipes. The use of the limiting plate 7 facilitates limiting the movement of different types of steel pipes. The following is disclosed:

[0038] The inner end of the limiting plate 7 is connected to a first spring 13, and the inner end of the first spring 13 is connected to the inside of the roller 6. The inner end of the limiting plate 7 is slidably connected to a locking block 14, and the inner end of the locking block 14 is arc-shaped. The inner end of the locking block 14 extends into the inside of the locking groove 15 to form a locking mechanism. The locking groove 15 is equally spaced inside the roller 6. The outer end of the locking block 14 is connected to a second spring 16, and the outer end of the second spring 16 is connected to the inside of the limiting plate 7. The outer end of the locking block 14 is connected to a pull rope 17, and the outer end of the pull rope 17 extends out of the inside of the limiting plate 7 through a pulley 18 to form a sliding mechanism. The pulley 18 is connected to the inside of the limiting plate 7 through a bearing.

[0039] refer to Figure 2 , Figure 6 and Figure 7When it is necessary to tighten steel pipes with different spacings, by pushing the limiting plate 7, the limiting plate 7 can slide on the roller 6. This movement of the limiting plate 7 compresses the first spring 13, causing it to be compressed. Furthermore, the movement of the limiting plate 7 moves the locking block 14, causing it to press against the locking groove 15. This compresses the locking block 14, causing it to move inwards from the limiting plate 7. The movement of the locking block 14 also compresses the second spring 16, causing it to be compressed. Finally, the locking block 14 disengages from the locking groove 15. The limiting plate 7 then... When the pipe is limited, the force of the second spring 16 pushes the locking block 14 into the slot 15 to engage, thereby fixing the position of the limiting plate 7 on the roller 6. This allows the limiting plate 7 to limit steel pipes of different sizes, thus preventing the steel pipe from shaking. By pulling the pull rope 17, the movement of the pull rope 17 can drive the locking block 14 through the pulley 18, causing the locking block 14 to disengage from the slot 15. Then, the force of the first spring 13 can push the limiting plate 7 to move, allowing the limiting plate 7 to reset, thus facilitating the next time the limiting plate 7 limits the steel pipe.

[0040] Working principle: When using this steel pipe stiffening ring assembly device, firstly, refer to... Figure 1 and Figure 2 The base 1 is placed on the ground, and the hydraulic rod 3 is extended and retracted by controlling the hydraulic rod 3, so that the hydraulic rod 3 can drive the connecting plate 4 to rotate. Then the connecting plate 4 can rotate around the bottom of the support rod 5 as the center, which can play a role in strengthening and then splicing the steel pipes together, which facilitates subsequent welding. Then, by rotating the steel pipe, it is easy to adjust the angle of the steel pipe, which facilitates welding at different positions of the steel pipe, thereby improving the welding efficiency.

[0041] refer to Figure 1 , Figures 3 to 5 When the position needs to be adjusted, the worm gear 9 is driven by the motor 8 to rotate, which in turn causes the worm wheel 10 to rotate and drives the inner rotating rod 11 to rotate. The rotation of the inner rotating rod 11 can then drive the transfer roller 12 to move. The base 1 can limit the transfer roller 12, and the transfer roller 12 can lift the base 1, thereby moving the position of the base 1. After moving to the position, the above operation is reversed, and the transfer roller 12 can be retracted into the base 1, so that the base 1 will contact the ground, thus facilitating the fixation of the position of the base 1.

[0042] refer to Figure 2 , Figure 6 and Figure 7When it is necessary to tighten steel pipes with different spacings, the limiting plate 7 is pushed, and the movement of the limiting plate 7 will drive the locking block 14 to move, so that the locking block 14 will be squeezed between the locking slot 15 and the locking block 14 will disengage from the locking slot 15. When the limiting plate 7 limits the steel pipe, the position of the limiting plate 7 can be fixed on the roller 6, thus preventing the steel pipe from shaking. By pulling the pull rope 17, the pull rope 17 can move through the pulley 18 to drive the locking block 14 to move, so that the locking block 14 will disengage from the locking slot 15. Then, the force of the first spring 13 can push the limiting plate 7 to move, so that the limiting plate 7 can be reset, thus facilitating the next time the limiting plate 7 limits the steel pipe.
