Description

Technical Field

[0001] The utility model relates to the technical field of pipeline butt welders, in particular to an adjustable butt welder for pressure pipeline installation construction. Background Technique

[0002] During the process of engineering construction, pipeline installation construction is a job item with relatively high quality requirements. Especially during the process of pipeline butt welding, as the main supporting equipment for automatic pipeline welding, the pipeline butt welder is mainly used to quickly butt two pipelines to be assembled together, and plays roles such as pipe orifice rounding, misalignment adjustment, and assembly gap adjustment. The quality and speed of pipeline butt welding are important prerequisites for affecting the overall quality and efficiency of the project.

[0003] For the butt welding of existing large-size pipeline butt welds, tools and machinery such as chain hoists, gantry frames or cranes need to be used. Fine adjustment of misalignment is difficult, and the work efficiency is low. Moreover, the operation of axially aligning the butt weld requires a relatively high skill level of pipe fitters. If the operation level of pipe fitters is not in place, problems such as misalignment and skew will occur. Therefore, a pipeline butt welder is needed to meet people's needs.

[0004] After retrieval, the patent application number is (202023280787.1), and "Butt Welder" is disclosed, which solves the problems that the methods for pipeline butt welding include manual butt welding and using a butt welder. The former has low butt welding accuracy, large errors, and low butt welding efficiency, and requires operators to have certain work experience; the latter is mostly in the form of hydraulic or pneumatic, which can ensure the butt welding accuracy and efficiency of the pipeline, but its volume is relatively heavy, and it is complicated to operate, with a high cost, and at the same time, the failure rate is also high;

[0005] However, the following problems exist in the above device: During traditional hoisting pipeline docking operations, multiple people are often required to operate. Moreover, during butt welding, it is necessary to measure the distance between the two pipelines to ensure accuracy. When there is an error, it is necessary to repeatedly disassemble and adjust, which reduces the construction efficiency. Moreover, the pipeline is easily worn during the disassembly and adjustment process, affecting the butt welding quality between the pipelines. The accuracy cannot be guaranteed during the operation process. For this reason, we propose an adjustable butt welder for pressure pipeline installation construction to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide an adjustable butt welder for pressure pipeline installation construction, so as to solve the problem in the above background technique that the accuracy cannot be guaranteed during the operation process, resulting in easy wear of the pipeline during the adjustment process and affecting the work efficiency of pipeline butt welding.

[0007] To achieve the above object, the present utility model provides the following technical solutions: an adjustable pipe alignment device for pressure pipeline installation construction, including an upper fixing frame and a lower fixing frame. Fixed blocks and connection blocks are respectively fixedly connected to both ends of the upper fixing frame and the lower fixing frame. Two groups of first rotating shafts are inserted into the fixed blocks at the lower fixing frame, and are rotationally connected to the connection blocks at the upper fixing frame through the first rotating shafts. A pin is inserted into the fixed block at the upper fixing frame. A moving component is arranged inside the upper fixing frame and the lower fixing frame, and a positioning component is arranged between the upper fixing frame and the lower fixing frame.

[0008] The moving component includes an activity groove, a connection seat, a ball, and a spring. Activity grooves are formed inside the upper fixing frame and the lower fixing frame. A connection seat is arranged inside the activity groove. A ball is arranged inside the connection seat. A spring is arranged inside the connection seat.

[0009] Preferably, the positioning component includes a connecting plate, an adjusting rod, a connecting piece, a moving block, and a second rotating shaft. Ten groups of connecting plates are respectively fixedly connected to the inner sides of the upper fixing frame and the lower fixing frame. Two groups of adjusting rods are threadedly connected inside the connecting plates. The bottom of the adjusting rod is rotationally connected to a connecting piece. A moving block is arranged at the lower end of the connecting piece. The moving block is rotationally connected to the connecting piece through a second rotating shaft.

[0010] Preferably, the connection seat is movably connected to the upper fixing frame and the lower fixing frame inside the activity groove. The ball is rotationally connected to the connection seat inside the connection seat. Two ends of the spring respectively abut against the connection seat and the inner wall of the activity groove.

[0011] Preferably, a limiting ring is fixedly connected to the inner side of the connection seat. The activity groove is T-shaped, and the diameter of the activity groove is adapted to the diameters of the limiting ring and the connection seat.

[0012] Preferably, a positioning disk is fixedly connected to the bottom of the moving block. The positioning disk is conical and made of rubber.

[0013] Preferably, a knob is fixedly connected to the top end of the adjusting rod. A rubber pad is arranged on the outer side of the knob, and the surface of the rubber pad is provided with wavy anti-slip lines with a depth of two millimeters.

[0014] Preferably, the outer surfaces of the upper fixing frame and the lower fixing frame are arc-shaped, and the diameter of the connection block is adapted to the fixed block.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. Through the setting of the moving component, the utility model, with the cooperation of the connecting seat, the ball and the spring, drives the upper fixing frame and the lower fixing frame to move along the outer wall of the pipeline through the ball. At the same time, it is convenient for the pipeline to rotate and adjust with the help of the ball and be adjusted to the specified position, solving the problems existing in various pipe aligners in the prior art, such as being more troublesome to use, unable to move flexibly, having low working efficiency in butt welding connection of different positions of the pipeline, and being prone to wear during the moving process.

[0017] 2. Through the setting of the positioning component, the utility model separates the upper fixing frame and the lower fixing frame, then fits them on the pipeline, and after merging the upper fixing frame and the lower fixing frame again, pre-locks them with a pin. Then, when the adjusting rod is rotated, the rotation of the adjusting rod will cause the movable block to move towards the outer wall of the pipeline in the direction opposite to the adjustment direction of the connecting piece, and finally, the pipeline is clamped tightly by the adjusting rod and the positioning disc, having a better fixing effect on any specified position of the pipeline and being more stable during installation; the setting of the connecting plate and the adjusting rod enables the device to be adapted to pipelines with different outer diameters to the greatest extent, with stronger practicability and safer use.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-5 , an embodiment provided by the present invention: An adjustable butt welder for pressure pipeline installation construction, including an upper fixing frame 1 and a lower fixing frame 2. Fixed blocks 3 and connecting blocks 4 are respectively fixedly connected to both ends of the upper fixing frame 1 and the lower fixing frame 2. Two groups of first rotating shafts 5 are inserted into the fixed blocks 3 at the lower fixing frame 2, and are rotationally connected to the connecting blocks 4 at the upper fixing frame 1 through the first rotating shafts 5. A bolt 6 is inserted into the fixed block 3 at the upper fixing frame 1. A moving component 7 is arranged inside the upper fixing frame 1 and the lower fixing frame 2, and a positioning component 8 is arranged between the upper fixing frame 1 and the lower fixing frame 2.

[0027] The moving component 7 includes an activity groove 71, a connecting seat 72, a ball 73 and a spring 74. Activity grooves 71 are opened in the upper fixing frame 1 and the lower fixing frame 2. A connecting seat 72 is arranged inside the activity groove 71. A ball 73 is arranged inside the connecting seat 72. A spring 74 is arranged inside the connecting seat 72.

[0028] Through the settings of the moving component 7 and the positioning component 8 in this device, the problem that it is impossible to ensure accuracy during the operation process, resulting in easy wear of the pipeline during the adjustment process and affecting the working efficiency of pipeline butt welding, is solved.

[0029] Furthermore, the positioning component 8 includes a connecting plate 81, an adjusting rod 82, a connecting piece 83, a movable block 84 and a second rotating shaft 85. Ten groups of connecting plates 81 are respectively fixedly connected to the inner sides of the upper fixing frame 1 and the lower fixing frame 2. Two groups of adjusting rods 82 are threadedly connected inside the connecting plates 81. The bottom of the adjusting rod 82 is rotationally connected to a connecting piece 83. The lower end of the connecting piece 83 is provided with a movable block 84. The movable block 84 is rotationally connected to the connecting piece 83 through the second rotating shaft 85. As Figure 5As shown, this structure is used to tightly hold the pipeline through the adjusting rod 82 and the positioning disk 10, which has a better fixing effect on any specified position of the pipeline, is more stable during installation, and at the same time, in the combined use of the connecting plate 81 and the adjusting rod 82, it is applicable to pipelines with different outer diameters and has stronger practicability.

[0030] Further, the connecting seat 72 is located in the movable groove 71 and is movably connected to the upper fixing frame 1 and the lower fixing frame 2. The ball 73 is located in the connecting seat 72 and is rotatably connected to the connecting seat 72. Both ends of the spring 74 are respectively abutted against the inner wall of the connecting seat 72 and the movable groove 71. As Figure 4 shown, this structure is used to facilitate the movement of the upper fixing frame 1 and the lower fixing frame 2 along the outer wall of the pipeline through the ball 73, adjust to the specified position, and avoid being difficult to adjust when there is an error, which affects the docking efficiency.

[0031] Further, a limiting ring 9 is fixedly connected to the inner side of the connecting seat 72. The movable groove 71 is T-shaped, and the diameter of the movable groove 71 is adapted to the diameters of the limiting ring 9 and the connecting seat 72. As Figure 2 shown, this structure is used to enable the connecting seat 72 to stably move up and down in the movable groove 71 through the limiting ring 9, and avoid the connecting seat 72 disengaging from the movable groove 71.

[0032] Further, a positioning disk 10 is fixedly connected to the bottom of the movable block 84. The positioning disk 10 is conical and made of rubber material. As Figure 3 shown, this structure is used to increase the contact area with the pipeline through the positioning disk 10, which has a better fixing effect on any specified position of the pipeline and is more stable during installation.

[0033] Further, a knob 11 is fixedly connected to the top of the adjusting rod 82. A rubber pad is arranged on the outer side of the knob 11, and the surface of the rubber pad is provided with wavy anti-slip lines with a depth of two millimeters. As Figure 3 shown, this structure is used for the rubber to have the characteristics of buffering and anti-slip. Its anti-slip lines can improve its anti-slip effect, and the depth of two millimeters can be used to ensure that the anti-slip lines still have an anti-slip effect after a certain degree of wear.

[0034] Further, the outer surfaces of the upper fixing frame 1 and the lower fixing frame 2 are arc-shaped to avoid scratching. The diameter of the connecting block 4 is adapted to the fixing block 3. As Figure 1 shown, this structure is used for the connecting block 4 and the fixing block 3 to be adapted to facilitate the clamping of the connecting block 4 in the fixing block 3 and facilitate the stable rotation of the connecting block 4.

[0035] Working principle: When in use, as Figure 1 and Figure 4As shown, rotate the upper fixing frame 1 and the lower fixing frame 2 and sleeved them on the surface of the pipeline. Slide on the surface of the pipeline by means of the rolling balls 73. After moving to the specified position, insert the connecting block 4 at the outer end of the lower fixing frame 2 into the fixing block 3 at the upper fixing frame 1, and then insert the pin 6 to fix the connecting block 4 and the first rotating shaft 5. At this time, if it is found that there is still a deviation in the position, the pipeline can be adjusted and rotated continuously by means of the rolling balls 73 until it is adjusted to the accurate position. After adjustment, as Figure 3 and Figure 5 shown, rotate the connecting piece 83 and the movable block 84, align the part to be fixed as required, and then rotate the knob 11 to drive the adjusting rod 82 to move towards the pipeline. Fix the pipeline under the action of the positioning disk 10. If the pipeline size is adapted to the upper fixing frame 1 and the lower fixing frame 2, as Figure 1 and Figure 4 shown, the same operation can be carried out. When the pin 6 fixes the connecting block 4 and the first rotating shaft 5, the rolling balls 73 are extruded and move into the movable groove 71, so that the connecting seat 72 pushes the spring 74, and the connecting seat 72 is contracted in the movable groove 71, improving the applicability of the device. The above is the whole working principle of the present utility model.

[0036] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
