Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, and particularly relates to an alignment device for pipeline welding. Background Technique

[0002] Publication No. CN217142928U discloses a docking and fixing device for pipeline welding. The docking and fixing device for pipeline welding includes an operating table.

The fixing component includes a base and a pressing plate that are pressed against each other. The base is provided with a first pipeline clamping plate, and the pressing plate is provided with a second pipeline clamping plate. After the base and the pressing plate are pressed together, the first pipeline clamping plate and the second pipeline clamping plate clamp and fix the pipeline to be welded; after the base and the pressing plate are pressed together, the axes of the first pipeline clamping plates in each fixing component are located on the same straight line. The fixing components respectively clamp and fix the pipelines to be welded, and the two pipelines to be welded are butted and then welded. This device uses the base and the pressing plate, and cooperates with the pipeline clamping plates to fix the pipeline to be welded, so as to ensure the docking stability of the pipeline, and has the characteristics of easy operation, high welding efficiency and high flexibility. However, the following problems still exist in the actual use of this patent:

[0003] When welding existing pipelines, it is necessary to flip the welding surface so that the butt joint is fully welded. However, the above device cannot rotate the welding surface when the pipeline is clamped. Therefore, it is necessary to unlock first, flip and then lock, which is too troublesome. Moreover, after the two pipelines are aligned, the above device lacks stable locking, resulting in that the longer pipeline may be unstable due to accidental shaking at the other end, and the two pipelines need to be realigned.

[0004] An alignment device for pipeline welding is proposed to solve the problems mentioned above. Content of the Utility Model

[0005] The purpose of the utility model is to provide an alignment device for pipeline welding to solve the problem that when welding existing pipelines, it is necessary to flip the welding surface so that the butt joint is fully welded. However, the above device cannot rotate the welding surface when the pipeline is clamped. Therefore, it is necessary to unlock first, flip and then lock, which is too troublesome as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An alignment device for pipeline welding, including a fixed seat;

[0007] A pipe clamping component is arranged on the top of the fixed seat. The pipe clamping component includes mounting bins symmetrically arranged on the top surface of the fixed seat. The mounting bins are slidably connected to the fixed seat, and a locking mechanism is arranged on the outer side of the mounting bins;

[0008] Among them, rotating rods are symmetrically and rotatably installed on both sides of the top of the installation bin. The upper half of the rotating rod is located above the installation bin. A lifting plate is fixedly installed on the outer side of the top of the rotating rod. A first bevel gear is rotatably connected to the top surface of the lifting plate. The first bevel gear is meshed with a second bevel gear. A transmission shaft is fixedly installed on the side of the second bevel gear. The transmission shaft rotates through the top of the rotating rod and is fixedly connected to a pressing wheel.

[0009] Preferably, an electric push rod is fixedly installed below the interior of the installation bin. The output end of the electric push rod faces upward and is fixedly installed with a pushing block. A sliding column is fixedly installed at the top end of the pushing block.

[0010] Preferably, the top end of the sliding column extends out of the installation bin and is installed with a supporting wheel. A knob is rotatably installed on the bottom surface of the lifting plate. The knob penetrates through the lifting plate and is fixedly connected to the first bevel gear.

[0011] Preferably, a connecting shaft is fixedly connected to the bottom of the rotating rod. A resisting wheel is rotatably connected to the connecting shaft. A pulling spring is fixedly installed between the connecting shafts on both sides.

[0012] Preferably, inclined surfaces are provided on both sides of the pushing block. The inclined surfaces are in rolling connection with the resisting wheel. The sliding column is slidably connected to the installation bin.

[0013] Preferably, the locking mechanism includes a limiting shell fixed to the outside of the installation bin. The limiting shell is slidably connected to the fixed seat. Movable columns are symmetrically and slidably connected to both sides of the limiting shell. A spring rod is fixedly connected to the ends of the movable columns close to each other.

[0014] Preferably, a sliding column is fixedly connected to the top of the ends of the movable columns close to each other. The sliding column is slidably connected to the limiting shell. A pinching block is fixedly connected to the top end of the sliding column.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: For this pipe welding alignment device, by the rotation of the pressing wheel to drive the rotation of the pipe, the pipe can directly turn over in place while being kept clamped, with quick operation, and it also avoids damage to the just welded part due to large-scale turning of the pipe. The specific content is as follows:

[0016] 1. By rotating the two knobs, the first bevel gear drives the second bevel gear to rotate, so that the transmission shaft drives the pressing wheel to rotate. And since the pressing wheel is clamped at this time, the rotation of the pressing wheel will drive the rotation of the pipe, so that the pipe can directly turn over in place while being kept clamped, with quick operation, and it also avoids damage to the just welded part due to large-scale turning of the pipe.

[0017] 2. By pinching the pinch block, the sliding column drives the movable column to move, so that the abutting block disengages from the fixed seat. Then, the installation bin together with the limit shell drives the pipeline to move horizontally, and makes the two pipelines fit and butt against each other, which is convenient for subsequent welding. After releasing the pinch block, the spring rod will push the two movable columns to make the abutting block fit the fixed seat, so as to ensure the butt joint of the two pipelines.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1-5 , the present utility model provides a technical solution: a butt joint device for pipeline welding, including a fixed seat 1; a horizontal groove is provided on the surface of the fixed seat 1, and both the installation bin 201 and the limit shell 301 are slidably connected to the horizontal groove;

[0026] A clamping tube assembly 2 is provided on the top of the fixed seat 1. The clamping tube assembly 2 includes mounting bins 201 symmetrically arranged on the top surface of the fixed seat 1. The mounting bins 201 are slidably connected to the fixed seat 1, and a locking mechanism 3 is provided on the outer side of the mounting bins 201.

[0027] Among them, rotating rods 206 are symmetrically and rotatably mounted on both sides of the top of the mounting bin 201. The upper half of the rotating rod 206 is located above the mounting bin 201. A lifting plate 210 is fixedly mounted on the outer side of the top of the rotating rod 206. A first bevel gear 211 is rotatably connected to the top surface of the lifting plate 210. The first bevel gear 211 is meshed and connected with a second bevel gear 213. A transmission shaft 214 is fixedly mounted on the side of the second bevel gear 213. The transmission shaft 214 rotates through the top of the rotating rod 206 and is fixedly connected with an extrusion wheel 215. A friction pad is adhered to the outer side of the extrusion wheel 215 to increase the friction between the extrusion wheel 215 and the pipeline, ensuring that the pipeline rotates when the extrusion wheel 215 rotates.

[0028] An electric push rod 202 is fixedly mounted below the interior of the mounting bin 201. The output end of the electric push rod 202 faces upward and is fixedly mounted with a push block 203. The top end of the push block 203 is fixedly mounted with a sliding column 204. The two side slopes of the push block 203 have a radian.

[0029] The top end of the sliding column 204 extends out of the mounting bin 201 and is mounted with a supporting wheel 205. A knob 212 is rotatably mounted on the bottom surface of the lifting plate 210. The knob 212 penetrates through the lifting plate 210 and is fixedly connected with the first bevel gear 211.

[0030] The bottom of the rotating rod 206 is fixedly connected with a connecting shaft 207. A pressing wheel 208 is rotatably connected to the connecting shaft 207. A pulling spring 209 is fixedly mounted between the two connecting shafts 207 on both sides. The pulling spring 209 can make the pressing wheel 208 always fit against the push block 203 by pulling the connecting shaft 207.

[0031] Both sides of the push block 203 are provided with slopes, which are in rolling connection with the pressing wheel 208. The sliding column 204 is slidably connected to the mounting bin 201.

[0032] The locking mechanism 3 includes a limiting shell 301 fixed to the outer side of the mounting bin 201. The limiting shell 301 is slidably connected to the fixed seat 1. Movable columns 302 are symmetrically and slidably connected to both sides of the limiting shell 301. One end of the movable columns 302 close to each other is fixedly connected with a spring rod 306. The other end of the movable columns 302 is fixedly connected with a blocking block 303. The blocking block 303 fits against the inner side of the fixed seat 1. A sliding column 304 is fixedly connected to the top of one end of the movable columns 302 close to each other. The sliding column 304 is slidably connected to the limiting shell 301. The top end of the sliding column 304 is fixedly connected with a pinching block 305. The blocking block 303 is a rubber pad with a high friction damping coefficient, and the fitting of the blocking block 303 against the mounting bin 201 can prevent the limiting shell 301 from moving.

[0033] Working principle: Before using a pipe butt joint device for pipe welding, it is necessary to first check the overall condition of the device to ensure that it can work properly. According to Figure 1 - Figure 5 As shown, first place the two pipes on the abutting wheels 208 respectively, and then start the electric push rod 202 so that the push block 203 drives the sliding column 204 to rise. At the same time, the inclined surface of the push block 203 will cause the rotating rod 206 to rotate by pushing the abutting wheel 208, so that the pressing wheel 215 can approach the pipe, and finally the pipe is quickly clamped;

[0034] At this time, pinch the pinch block 305 so that the sliding column 304 drives the movable column 302 to move, so that the abutting block 303 is separated from the fixed seat 1, and then the installation bin 201 together with the limit shell 301 drives the pipe to move horizontally, and the two pipes are mutually abutted and docked, which is convenient for subsequent welding. After releasing the pinch block 305, the spring rod 306 will push the two movable columns 302 to fit the abutting block 303 to the fixed seat 1, so that the two pipes are guaranteed to be docked;

[0035] After the surface welding is completed, rotate the two knobs 212 so that the first bevel gear 211 drives the second bevel gear 213 to rotate, so that the transmission shaft 214 drives the pressing wheel 215 to rotate. And because the pressing wheel 215 is clamped at this time, the rotation of the pressing wheel 215 will drive the pipe to rotate at this time, so that the pipe directly turns over in place while keeping clamped, and it also avoids damage to the just-welded place caused by turning the pipe greatly.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
