Abstract
Description
Technical Field
[0001] The utility model relates to pipeline installation auxiliary equipment, more specifically, it relates to a large-diameter pipeline butt fixing device. Background Art
[0002] In the construction of large factories, large-diameter pipes are often buried. Since the diameter of these large-diameter pipes is generally more than one meter, the joints of two large-diameter pipes need to be welded to achieve a more reliable connection. The usual practice is to place the large-diameter pipe in a groove, and after the two large-diameter pipes are butt-jointed, the worker places the welding device on site, and then starts the welding device to weld the joints of the two pipes. In order to facilitate the welding work below the large-diameter pipe, it is necessary to dig an operation pit below the joint of the two pipes so that the workers can drill into the joint to perform welding work. However, since the large-diameter pipe in the operation pit is in a suspended state, the end of the pipe will sag, and the longer the operation pit, the more suspended parts of the pipe, and the greater the sag of its end. This will cause the two large-diameter pipes to have different axes of the butt joint, resulting in different sizes of butt joint gaps at each position of the butt joint, with a gradient seam of small upper part and large lower part. This is not only not conducive to welding, but also leads to poor welding quality, and an increase in the number of empty welds and false welds. Utility Model Content

DETAILED DESCRIPTION
[0017] The utility model is further described below in conjunction with the embodiments, but does not constitute any limitation to the utility model. Any limited modifications made by anyone within the scope of the claims of the utility model are still within the scope of the claims of the utility model.
[0018] See also Figure 1-Figure 3 The utility model discloses a large diameter pipe docking fixing device, comprising a pad 1. A support seat 1 3 and a support seat 2 10 are fixed at both ends above the pad 1, and an operation space 2 is provided between the support seat 1 3 and the support seat 2 10. The operation space 2 allows an operator to enter and perform welding operations therein, so that the operator can weld the lower position of the docking point of two diameter pipes. A jack 1 4 is fixedly installed above the support seat 1 3, a seat body 1 5 is installed on the jack 1 4, and a bearing plate 1 7 is installed above the seat body 1 5, which is used to support one of the large diameter pipes. A jack 2 15 is provided in the support seat 2 10, and the horizontal installation height of the jack 2 15 is consistent with the horizontal installation height of the jack 1 4, so that the initial positions of the two jacks are in a horizontal state, so as to facilitate the installation and alignment of the fixing device, so that it is in a horizontal state. A seat body 2 16 is installed on the jack 2 15, and a bearing plate 2 18 is installed above the seat body 2 16, which is used to support the other large diameter pipe. By supporting and positioning the ends of the large-diameter pipes with two jacks, the joints of the two large-diameter pipes can be in a horizontal state, thereby solving the problem of different sizes of joint gaps at different positions of the joints of the two large-diameter pipes caused by the ends of the large-diameter pipes drooping due to being suspended in the air, thereby improving the welding effect of the joints.
[0019] Considering that after the two pipes are lifted to the horizontal level by the jack, there may be a large gap at the joint of the two pipes, a driving assembly that can drive the jack 15 to move in the horizontal direction is installed in the support seat 10 of this embodiment, and an electromagnet is fixedly embedded in the bearing plate 18. After the electromagnet is energized, the large-diameter pipe is adsorbed, and then the jack 15 and the large-diameter pipe above it are driven by the driving assembly to approach the other large-diameter pipe, thereby reducing the gap at the joint of the two large-diameter pipes, making the two large-diameter pipes fit tightly, and greatly improving the welding effect.
[0020] In this embodiment, the driving assembly includes a gear reduction box 12, a screw 20 and a guide rod 13. The support seat 10 is provided with an installation cavity 11, and the gear reduction box 12 is fixedly installed in the installation cavity 11. The input end of the gear reduction box 12 is a hexagonal shaft head, which can be rotated by a tool, so that its output end rotates. The output end of the gear reduction box 12 is fixedly installed with a screw 20, and a slider 14 is screwed on the screw 20. Two guide rods 13 are fixedly installed between the gear reduction box 12 and the wall of the installation cavity 11. The two guide rods 13 are symmetrically arranged with the screw 20 as the symmetry center. Both guide rods 13 are slidably inserted in the slider 14, and the jack 15 is fixedly installed above the slider 14. When the output end of the gear reduction box 12 rotates, it will drive the screw 20 to rotate, so that the slider 14, the jack 15, the bearing plate 18, the electromagnet and the large diameter pipe adsorbed by the electromagnet move, so that the two large diameter pipes are close and close.
[0021] In order to ensure that the moving ends of the two jacks are on the same horizontal plane after operation, a laser transmitter 8 is installed on the side of the seat body 1 5 close to the seat body 2 16 of this embodiment, and a laser receiver 19 is installed on the side of the seat body 2 16 close to the seat body 1 5. The laser receiver 19 is electrically connected to an alarm through a controller. The alarm can be installed on the pad 1 or the support seat. After the jack is operated, when the laser receiver 19 receives the laser emitted by the laser transmitter 8, it means that the bearing plates above the two jacks are on the same horizontal plane after operation, that is, the joints of the two large-diameter pipes are coaxial.
[0022] Preferably, both the bearing plate 1 7 and the bearing plate 2 18 are arc-shaped, and the curvature of the bearing plate 1 7 and the bearing plate 2 18 is consistent with the curvature of the large-diameter pipe, so that the bearing plates can effectively support the large-diameter pipe.
[0023] Preferably, a square hole 1 is provided in the seat body 15, a square block 16 matching therewith is inserted in the square hole 1, a bearing plate 17 is fixedly installed above the square block 16, and a pin 9 for positioning the square block 16 is inserted in both the seat body 15 and the square block 16. A square hole 2 is provided in the seat body 216, a square block 217 matching therewith is inserted in the square hole 2, a bearing plate 218 is fixedly installed above the square block 217, and a pin 2 for positioning the square block 217 is inserted in both the seat body 216 and the square block 217. With such a design, the two bearing plates can be disassembled and replaced, so that they can be used to match large-diameter pipes of different diameters.
[0024] The working principle of the utility model is: when the sizes of the butt joint gaps at different positions of the butt joint are different after two large-diameter pipes are butt jointed, the ground below the butt joint of the two large-diameter pipes is leveled, and then the fixing device is placed below the butt joint of the two large-diameter pipes. The pad 1 is detected by a level ruler, and after the level is determined, the butt joint fixing operation of the large-diameter pipes can be performed. Specifically, two jacks are started at the same time, so that the bearing plate above them is pressed against the corresponding large-diameter pipe above them, and then the jacks are fine-tuned to make the moving end rise, and the operation of the jacks is stopped after the sizes of the butt joint gaps at various locations between the two large-diameter pipes are visually consistent. At this time, if the alarm does not sound, it means that the laser receiver 19 can receive the laser signal emitted by the laser transmitter 8, and the laser receiver 19 generates a feedback signal to the controller, so that it does not start the alarm.
[0025] After the fixture completes the coaxial leveling support for the two large-diameter pipes, if the butt gap is large, the electromagnet is powered on, and then the output end drives the screw 20 to rotate through the input end of the tool shaft gear reducer box 12, so as to drive the large-diameter pipe to move toward the other large-diameter pipe through the slider 14, reduce the butt gap, and make the butt joint of the two large-diameter pipes fit tightly. It should be noted that the electromagnet needs to be powered off during welding.
[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
