Description

Technical Field

[0001] The utility model belongs to the field of thermal pipeline construction, and specifically relates to a thermal pipeline welding auxiliary device. Background Art

[0002] The thermal pipelines in the existing technology start from the boiler room, direct-fired machine room, heating center, etc., and are connected from the heat source to the thermal entrance of the building. Multiple heating pipelines form a pipe network. When welding between thermal pipelines, the thermal pipelines are generally lifted by a crane. During the welding process, the crane must always hold the pipeline to facilitate welding by the workers.

[0003] A Chinese patent with announcement number CN217316669U discloses a thermal pipeline welding auxiliary device, including a pull belt, a crossbeam, a hanger and a pull arm. The crossbeam is located above the thermal pipeline, and the hanger is connected to the bottom of the crossbeam. The two ends of the hanger are slidably connected to the pull arms. The lower ends of the two pull arms are connected to pull belts that support the thermal pipeline, which can replace the support and fixation of the thermal pipeline during the welding process.

[0004] In the above-mentioned comparative document, the thermal pipe is supported and fixed by the pull arms and pull straps on both sides. The length of the pull arms is fixed. There will be space between the thermal pipe and the hanger during the clamping process. Shaking may occur during the welding of the thermal pipe. After the welding is completed, the staff needs to bend down to release the pull strap at the lower end of the pull arm, which is inconvenient to operate.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a thermal pipeline welding auxiliary device.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0008] A thermal pipeline welding auxiliary device comprises: a horizontal plate, a fixed frame is slidably matched at the bottom of the horizontal plate, moving blocks are slidably matched at opposite sides of the horizontal plate, a threaded column is threadedly matched at one side of the moving block, a support plate is rotatably matched at the bottom of the threaded column, and a clamping assembly is arranged in the fixed frame;

[0009] The clamping assembly includes a clamping plate that slides on opposite sides of the fixed frame, a supporting plate that rotates on both sides of the bottom of the fixed frame, and a support column that slides in the fixed frame. The clamping plate cooperates with the support column and the supporting plate. A fixed assembly is provided on one side of the fixed frame, and the fixed assembly cooperates with the support column.

[0010] Optionally, a threaded rod is rotatably engaged on one side of the cross plate, a vertical block is installed on the top of the fixed frame, a threaded hole is opened on one side of the vertical block, the threaded rod is threadedly engaged in the threaded hole, fixed columns are installed on opposite sides of the fixed frame, and fixed cylinders are installed on opposite sides of the bottom of the cross plate, and the fixed columns are slidably engaged in the fixed cylinders; the threaded rod is rotated to drive the fixed frame to slide up and down at the bottom of the cross plate, so that the height of the fixed frame can be adjusted conveniently to clamp and fix the thermal pipe, thereby reducing the instability of the thermal pipe during welding.

[0011] Optionally, sliding grooves are provided on opposite sides of the cross plate, and the moving block slides in the sliding grooves. A first tooth plate is installed on one side of the moving block, and one side of the cross plate rotates to cooperate with the first gear. The first tooth plates on both sides are located on both sides of the first gear and mesh with it, and an operating block is installed on one side of the first gear. The first gear is driven to rotate by rotating the operating block, and because the tooth plates on both sides are located on both sides of the first gear and mesh with it, the moving blocks on both sides are driven to move relative to each other, so that the support plate on the moving block can be placed on pipeline trenches of different widths.

[0012] Optionally, a connecting frame is provided between the support column and the clamping plates on both sides, a fixed block is installed on one side of the support column, a support block is installed on the bottom of the support column, one end of the connecting frame is rotatably engaged with the fixed block, and the other end of the connecting frame is rotatably engaged with the clamping plate, a first through groove and a second through groove are opened in the fixed frame, the support column slides in the second through groove, a first spring is installed on the top of the fixed block, the other end of the first spring is installed on the inner wall of the fixed frame, a rotating column is rotatably engaged in the first through groove, one side of the support plate is installed on the rotating column, a second gear is installed on one side of the rotating column, and a second tooth plate is installed on one side of the clamping plate, and the second tooth plate is meshed with the second gear.

[0013] Optionally, the fixing assembly includes a blocking block installed on one side of the fixing block and a movable plate slidably fitted in the fixing frame. A plurality of blocking slots are opened on one side of the movable plate, and the blocking block cooperates with the blocking slots. A pulling block is installed on one side of the movable plate, and a second spring is arranged between the pulling block and the movable plate, and the second spring is located in the fixing frame. When the resisting column moves downward, the blocking block on the fixing block is thereby driven to move downward, and the hypotenuse of the blocking block is arranged downward so that it is located in blocking slots at different positions and plays a clamping role thereon. By pulling the pulling block, the movable plate is driven to slide in the fixing frame, so that the blocking slot is separated from the blocking block, and the resisting column is driven downward by the action force of the first spring, thereby releasing the clamping and fixation of the thermal pipe.

[0014] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0015] The thermal pipe welding auxiliary device can be adapted to pipe trenches of different widths by adjusting the moving blocks on both sides of the cross plate. The thermal pipe is positioned between the clamping plates on both sides by moving the fixing frame downward. The thermal pipe abuts against the abutting columns, thereby driving the clamping plates on both sides to clamp it. At the same time, the supporting plates on both sides are driven to rotate to lift the bottom of the thermal pipe, so that the thermal pipe is positioned in the fixing frame to clamp and fix it stably. After welding is completed, the clamping plates on both sides can simultaneously drive the supporting plates on both sides to rotate in the opposite direction when moving to both sides, so that the fixing frame can be removed from the welded thermal pipe for easy operation.
