Description

Technical fields:

[0001] This utility model relates to the technical field of pressure installation equipment and tools, and more specifically to a correction support mechanism for pressure pipeline installation and docking. Background technology:

[0002] When installing existing pressure pipelines, flange connections or welding are generally used. For welded connections, it is necessary to ensure that the connection ends of the two pressure pipelines are aligned and pressed together before welding can be carried out. Since the pipelines are generally cylindrical, after alignment and pressing, they need to be manually supported or fixed. The current method is to manually support them while another person welds, which is ineffective and labor-intensive. In particular, if the person supporting them does not keep them aligned, it will affect the accuracy and effect of the welding.

[0003] Therefore, some require the use of fixing equipment to secure the connection ends of the two pipes before welding. However, the existing fixing equipment only supports the ends of the pipes and also needs to ensure that the ends of the two pipes are close together. In this case, it is necessary to first ensure that the ends of the two pipes are pressed together before fixing them with auxiliary fixing equipment. However, during fixing, there will be slight deviations in the position of the pipes, which can easily cause the two ends that were originally pressed together to separate. It is necessary to loosen the clamping parts again, adjust, and fix them again. The installation and adjustment are very troublesome and inconvenient. Utility Model Content:

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a correction support mechanism for the installation and docking of pressure pipelines. It can clamp the end of the pressure pipeline and make lateral fine adjustments to ensure that the welding ends of the two pressure pipelines are aligned and pressed together, which facilitates welding and fixing. It is easy to adjust and has good performance.

[0020] For example, see below. Figures 1 to 3 As shown, a correction support mechanism for installing and connecting pressure pipelines includes a horizontal fixed plate 10.

The top of the vertical screws 21 extends out of the top surface of the corresponding part of the lifting adjustment support block 30 and is formed with a rotating part.

[0025] The bottom surface of the lifting and adjusting support block 30 is formed with a collar portion 31, and the top surface of the lower support plate 20 is formed with a recessed hole.

The top end of the buffer spring 1 is inserted into the collar portion 31, and its top end presses against the bottom surface of the lifting and adjusting support block 30.

[0026] The top surface of the lifting and adjusting support block 30 has a lower arc-shaped groove 32 that runs through the left and right sides, and the bottom surface of the upper pressing block 40 has an upper arc-shaped groove 41 that runs through the left and right sides. Two anti-slip elastic blocks 50 are nested in the corresponding lower arc-shaped groove 32 and upper arc-shaped groove 41 respectively. The corresponding arc-shaped wall surface of the anti-slip elastic block 50 presses against the inner wall surface of the corresponding lower arc-shaped groove 32 or upper arc-shaped groove 41. At the same time, in order to ensure the fixing effect, the corresponding arc-shaped wall surface of the anti-slip elastic block 50 is bonded and fixed to the inner wall surface of the corresponding lower arc-shaped groove 32 or upper arc-shaped groove 41 by adhesive.

[0027] Furthermore, the front and rear of the anti-slip elastic block 50 are both formed with an extension connection 51, which presses against the top surface of the front and rear of the corresponding lifting adjustment support block 30 or the bottom surface of the front and rear of the corresponding upper pressing block 40.

[0028] The top surface of the lifting adjustment support block 30 is fixed with vertically extending adjustment screws 33 at the front and rear left and right sides. The adjustment screws 33 are inserted into the through holes of the corresponding extension connecting parts 51 of the two anti-slip elastic blocks 50. The top end of the adjustment screws 33 extends out of the corresponding upper vertical through hole at the front or rear of the upper pressing block 40 and is fitted with washers 2 and screwed with locking nuts 3. The bottom surface of the locking nuts 3 presses against the top surface of the corresponding washers 2, and the bottom surface of the washers 2 presses against the top surface at the front or rear of the upper pressing block 40.

[0029] Clamping grooves are formed on the opposite wall surfaces of the middle part of the two anti-slip elastic blocks 50. The corresponding part of the pressure pipe 100 is located in the two corresponding clamping grooves, and its outward part is pressed against the inner wall of the corresponding clamping groove.

[0030] Metal plates 4 are fixed on the upper and lower opposing walls of the extension connecting parts 51 of the two anti-slip elastic blocks 50. The metal plates 4 have a central through hole that is aligned with and communicates with the through hole of the corresponding extension connecting part 51. The spring 5 is inserted into the corresponding adjusting screw 33. The adjusting screw 33 is inserted into the central through hole of the corresponding metal plate 4. The two ends of the spring 5 are pressed against the two corresponding metal plates 4.

[0031] In this embodiment, pressure pipes 100 of different specifications require the use of anti-slip elastic blocks 50 with clamping grooves corresponding to their outer side walls. The anti-slip elastic blocks 50 are fixed with the corresponding lifting adjustment support blocks 30 or upper clamping blocks 40. Therefore, lifting adjustment support blocks 30 and upper clamping blocks 40 of the corresponding specifications are required. During installation, first fix a horizontal fixing plate 10 on the ground near the location where the two pressure pipes 100 need to be welded together, and then install other corresponding components. It is necessary to ensure that the two corresponding clamping grooves of this embodiment are corresponding left and right and basically aligned.

[0032] Insert the corresponding part of the pressure pipe 100 into the two corresponding clamping grooves. By rotating the locking nut 3, the outer wall surface of the corresponding part of the pressure pipe 100 is clamped between the two corresponding anti-slip elastic blocks 50. It needs to be rotated to ensure that the anti-slip elastic blocks 50 are pressed tightly and that the connection between them and the pressure pipe 100 is firm. At this point, the pressure pipe 100 will no longer shift. Then, rotate the corresponding push screw 13 to move the lower support plate 20 relative to each other, so that the welded ends of the two pressure pipes 100 are close together. Before pressing them together, you can observe their position. If they are not aligned vertically, you can rotate the corresponding multiple vertical screws. Rod 21 changes the height of the lifting adjustment support block 30, thereby changing the height of the pressure pipe 100 to align its height. If it is not aligned, the bolts connecting the horizontal fixing plate 10 can be loosened to make a slight adjustment to the horizontal fixing plate 10. The threaded part of the bolt is inserted into the corresponding oblong through hole extending forward and backward in the horizontal fixing plate 10 (the bolt and oblong through hole are not shown in the attached figure). Therefore, the horizontal fixing plate 10 can be slightly adjusted forward and backward. After the adjustment is completed, tighten the bolt. Then, rotate the push screw 13 to make the welding ends of the two pressure pipes 100 close together. Then, manual welding can be performed, which is very convenient.

[0033] The anti-slip elastic block 50 in this embodiment is made of high-temperature resistant silicone and other materials, which are conventional materials and will not be described in detail. At the same time, the clamping position and the welding end in this embodiment need to be at least 500mm apart to reduce the impact of temperature on the anti-slip elastic block 50.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
