Description

Technical Field

[0001] This utility model belongs to the field of pipeline welding technology, specifically relating to an auxiliary positioning device for welding installation of chemical pipelines. Background Technology

[0002] Chemical pipelines are a crucial infrastructure in the chemical industry, used to safely and efficiently transport various fluids (liquids, gases, slurries), connecting production equipment, storage tanks, processing units, etc., forming the "vascular system" of the chemical production process. The ends of chemical pipelines need to be welded with flanges, which provide detachable connection interfaces between pipelines and between pipelines and equipment.

[0003] Currently, when welding flanges on chemical pipelines, it is necessary to manually align and fix the flange and steel pipe. This process usually relies on an auxiliary support frame structure to achieve stable positioning. However, the auxiliary support frame is usually manufactured separately according to the actual pipeline and flange conditions, which makes it unsuitable for welding auxiliary use of steel pipes and flanges of different specifications. Utility Model Content

[0004] Based on the problems mentioned in the background technology above, this utility model provides a chemical pipeline installation welding auxiliary positioning device to solve the problem that when welding pipelines and flanges, the auxiliary support frame structure is used to achieve stable positioning. However, the auxiliary support frame is usually manufactured separately according to the actual pipeline and flange conditions, which leads to the problem that it is not suitable for welding auxiliary use of steel pipes and flanges of different specifications.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A chemical pipeline installation welding auxiliary positioning device, comprising:

[0007] cylindrical body;

[0008] An adjustable internal support component is provided on the outer peripheral wall of the rear middle section of the cylinder.

[0009] A telescopic clamping component is disposed on the front peripheral wall of the cylinder body;

[0010] An adjusting component is disposed inside the front end of the cylinder and is used to adjust the telescopic clamping component to expand outward or retract inward.

[0011] Based on the above technical solution, the present invention has made the following improvements:

[0012] Furthermore, the adjustable inner support component includes an annular groove, which is disposed on the outer peripheral wall of the front middle part of the cylinder. A collar is slidably sleeved in the annular groove, and a retaining seat is disposed on the outer peripheral wall of the collar. A fixed seat is disposed on the front peripheral wall of the cylinder, and a screw is screwed into the fixed seat. One end of the screw is rotatably locked in the retaining seat, and the other end of the screw is provided with a lever.

[0013] Multiple hinge seats are provided on the outer peripheral wall of the collar and the outer peripheral wall of the rear end of the cylinder. Each hinge seat is hinged with a stop post, and a support block is hinged between the opposite ends of two stop posts at the front and rear positions.

[0014] Furthermore, the telescopic clamping component includes multiple columns, each column array being arranged on the front peripheral wall of the cylinder. Each column has a locking hole, and each locking hole has a mounting hole at its bottom. Each mounting hole communicates with the interior of the front cylinder of the cylinder. Each locking hole has a screw cylinder, and each screw cylinder has a stud screwed into it. One end of each stud screw is rotatably locked in the corresponding mounting hole and extends into the interior of the front cylinder of the cylinder. Each screw cylinder has a mounting plate at its top, and each mounting plate has a stabilizing rod at its bottom. Each stabilizing rod passes through a stabilizing hole in the corresponding column. Each mounting plate has a clamping block at its top, and the clamping block faces the rear end of the cylinder.

[0015] Furthermore, each of the columns is arranged perpendicular to the cylinder, and each of the clamping blocks is arranged parallel to the cylinder.

[0016] Furthermore, the adjusting component includes a cover, a fixing plate, and a second bevel gear. The cover is disposed inside the front end of the cylinder, and the fixing plate is disposed inside the front end of the cylinder. An installation shaft is rotatably disposed between the cover and the fixing plate. A first bevel gear is disposed on the installation shaft. A rotating frame is disposed on the end of the installation shaft that extends through to the outside of the cover. The second bevel gear is disposed on the end of each stud that extends into the front end of the cylinder. Each second bevel gear meshes with the first bevel gear.

[0017] The beneficial effects of this utility model are:

[0018] 1. By combining the cylindrical body and adjustable internal support components, the cylindrical body is inserted into the pipe during use, and then the adjustable internal support components are used to fasten the internal support to the inner wall of the pipe, thereby achieving a stable assembly of the cylindrical body in the pipe. The adjustable internal support components can be adjusted to be suitable for pipes with different inner diameters.

[0019] 2. By combining the telescopic clamping components and the adjusting components, after the cylinder is securely assembled inside the pipeline using the adjustable inner support components, the telescopic clamping components are located outside the pipeline port. At this time, the cooperation of the telescopic clamping components and the adjusting components can be used to securely clamp the flange at the pipeline port so that welding operations can be carried out between the pipeline end and the flange. Furthermore, the telescopic clamping components, in conjunction with the adjusting components, can be expanded outwards / contracted inwards to accommodate flanges of different outer diameters.

[0027] like Figures 1-4 As shown, a chemical pipeline installation welding auxiliary positioning device includes:

[0028] Cylinder 101;

[0029] An adjustable internal support component is provided on the outer peripheral wall of the rear middle section of the cylinder 101. The adjustable internal support component includes an annular groove 201, which is located on the outer peripheral wall of the front middle section of the cylinder 101. A collar 202 is slidably fitted inside the annular groove 201. A retaining seat 206 is provided on the outer peripheral wall of the collar 202. A fixed seat 207 is provided on the front peripheral wall of the cylinder 101. A screw 208 is threaded into the fixed seat 207. One end of the screw 208 is rotatably locked in the retaining seat 206. The screw 208 can rotate independently relative to the retaining seat 206, that is, the screw 208 rotates within the retaining seat 206. The other end of the screw 208 is provided with a lever 209. By rotating the lever 209, the screw 208 can be rotated and moved. When the screw 208 rotates and moves, it can drive the collar 202 to move within the annular groove 201.

[0030] Multiple hinge seats 203 are provided on the outer peripheral wall of the collar 202 and the outer peripheral wall of the rear end of the cylinder 101. Each hinge seat 203 is hinged with a stop post 204. The stop post 204 can rotate on the hinge seat 203. The opposing ends of two stop posts 204 at the front and rear positions are hinged together with a support block 205. The stop post 204 can also rotate on the support block 205.

[0031] By extending the middle and rear section of the cylinder 101 into the pipe, and then rotating the lever 209 to rotate the screw 208, when the screw 208 rotates and moves towards the rear end of the cylinder 101, it can drive the collar 202 to move towards the rear end of the cylinder 101 within the annular groove 201. During the movement of the collar 202 towards the rear end of the cylinder 101, the corresponding ends of each abutment 204 can rotate around the hinge seat 203 and the support block 205 respectively. At this time, under the abutment action of the corresponding abutment 204, each support block 205 can move towards the inner wall of the pipe, causing each support block 205 to be tightly supported on the inner wall of the pipe, thereby achieving the stable assembly of the cylinder 101 in the pipe. Since each support block 205 can be adjusted in the radial direction of the pipe, it can be used for pipes with different inner diameters.

[0032] A telescopic clamping component is disposed on the front peripheral wall of the cylinder 101. The telescopic clamping component includes multiple columns 301, which are arrayed on the front peripheral wall of the cylinder 101. Each column 301 is perpendicular to the peripheral wall of the cylinder 101. Each column 301 has a locking hole 302, and each locking hole 302 has a mounting hole 303 at its bottom. Each mounting hole 303 communicates with the interior of the front cylindrical part of the cylinder 101. A screw cylinder 304 is inserted into each locking hole 302, allowing it to move up and down within the locking hole 302. A stud 305 is threaded into each screw cylinder 304, and one end of each stud 305 is rotatably engaged with the corresponding mounting hole 303. The screw cylinder 304 extends into the front end of the cylinder 101. Each screw cylinder 304 has a mounting plate 308 at its top and a stabilizing rod 306 at its bottom. Each stabilizing rod 306 passes through a stabilizing hole 307 in the corresponding column 301. By locking the stabilizing rod 306 in the stabilizing hole 307, the mounting plate 308 and screw cylinder 304 can be rotated and limited, preventing the screw cylinder 304 and mounting plate 308 from rotating when the stud 305 rotates. Each mounting plate 308 has a clamping block 309 at its top. Each clamping block 309 faces the rear end of the cylinder 101 and is parallel to the cylinder 101, so that the clamping block 309 and the column 301 are distributed at right angles.

[0033] An adjusting component is disposed inside the front end of the cylinder 101. The adjusting component includes a cover 401, a fixing plate 402, and a bevel gear 406. The cover 401 is disposed inside the front end of the cylinder 101, and the fixing plate 402 is disposed inside the front end of the cylinder 101. A mounting shaft 403 is rotatably disposed between the cover 401 and the fixing plate 402. A bevel gear 404 is disposed on the mounting shaft 403. A rotating bracket 405 is disposed on the end of the mounting shaft 403 that extends outside the cover 401. Each stud 305 extends to the end inside the front end of the cylinder 101. Each component is equipped with a second bevel gear 406, which meshes with a first bevel gear 404. By rotating the rotating frame 405, the mounting shaft 403 can be rotated to drive the first bevel gear 404 to rotate. When the first bevel gear 404 meshes with each second bevel gear 406, each stud 305 can rotate within the mounting hole 303. When each stud 305 rotates simultaneously, each screw barrel 304 can move up / down, thereby driving each clamping block 309 to move up / down, ultimately enabling each clamping block 309 to expand outward / retract inward.

[0034] In use, first fasten the flange to the end of the pipe, so that the center of the flange is roughly aligned with the center of the pipe. Then, extend the middle and rear section of the cylinder 101 into the pipe along the inner cavity of the flange. Then, rotate the lever 209 to make the screw 208 rotate. When the screw 208 rotates and moves towards the rear end of the cylinder 101, it drives the collar 202 to move towards the rear end of the cylinder 101 in the annular groove 201. During the process of the collar 202 moving towards the rear end of the cylinder 101, the corresponding ends of each abutment 204 can rotate around the hinge seat 203 and the support block 205 respectively. At this time, under the abutment action of the corresponding abutment 204, each support block 205 can move towards the inner wall of the pipe, so that each support block 205 is tightly supported on the inner wall of the pipe, thereby realizing the stable assembly of the cylinder 101 in the pipe.

[0035] Then, by turning the rotating frame 405, the mounting shaft 403 rotates, driving the bevel gear 404 to rotate. When the bevel gear 404 meshes with each bevel gear 406, each stud 305 rotates within the mounting hole 303. When each stud 305 rotates simultaneously, each screw cylinder 304 moves downward, thereby driving each clamping block 309 to move downward, causing each clamping block 309 to clamp onto the flange's peripheral wall, and causing each mounting plate 308 to press tightly against the flange's side wall, thus ultimately clamping the flange securely at the pipe's end for welding operations between the pipe end and the flange.

[0036] Since each support block 205 can be adjusted in the radial direction of the pipe, it can be used for pipes with different inner diameters. Since each clamping block 309 can expand outward / retract inward, it can be used for clamping flanges with different outer diameters.
