Description

Technical Field

[0001] The invention relates to the technical field of pipeline connection, in particular to an electric fusion connection support device for carat pipes. Background Art

[0002] Carat pipe (also known as hot-wound high-density polyethylene wound structural wall pipe) is a special structural wall pipe made of high-density polyethylene resin as the main raw material and manufactured using a hot-wound process. This pipe has a high resistance to external pressure and is widely used in urban drainage and sewage treatment.

[0003] At present, in the production process of carat tubes, in order to facilitate the connection between two tubes, electric fuses are usually pre-buried at the ends of the tubes. This pre-buried electric fuse does not require additional pipes when connecting two carat tubes. Instead, the heat generated by the electric fuse melts the connecting part of the tubes, thereby ensuring the accuracy and reliability of the connection.

[0004] However, there are some shortcomings in the method of manually pre-embedding electric fuses in the prior art. Specifically, in the process of pre-embedding the electric fuse to the port of the carat tube, workers usually use one hand to stick the electric fuse to the inner wall of the carat tube, and use the other hand to control the nail gun to move along the inner wall of the carat tube, so as to fix the electric fuse at the port of the tube. Subsequently, the electric fuse is energized to heat it and melt the surrounding tubing, so that the electric fuse is embedded in the port of the carat tube. This method of fixing the electric fuse is relatively cumbersome to operate, and will reduce work efficiency during the mass production of carat tubes. In addition, since the electric fuse will extrude the surrounding melted tubing parts when embedded in the port of the carat tube, it will cause unevenness at the port of the carat tube, requiring additional manual leveling treatment, which increases the complexity of the operation. Summary of the invention

[0005] In view of this, the present invention provides an electric fusion connection support device for carat tubes, which can overcome the disadvantages of the existing method of pre-embedded electric fuses, which is relatively complicated to operate and leads to low working efficiency of carat tubes in the batch production process.

The inflation component is used to inflate the airbag.

[0010] As an improvement of the above scheme, the inflation component includes an air pump, a connecting pipe and an electric control valve. The air pump is symmetrically connected to the outer wall of the rotating cylinder, the connecting pipe connects the airbag and the air outlet of the air pump, and the electric control valve is installed on the connecting pipe.

[0032] like Figure 7 and Figure 8As shown, it also includes a fixing ring 21, a guide rod 22, a sleeve 23, a locking screw I 24, a fixing block 25, a rotating block 26, a torsion spring 27 and a conductive sheet 28. The fixing ring 21 is connected to the middle of the outer wall of the fixing cylinder 2, the guide rod 22 is connected to the top surface of the fixing ring 21, the right side of the guide rod 22 is a vertical plane, the sleeve 23 is slidably connected to the guide rod 22, the locking screw I 24 is threadedly connected to the right side of the sleeve 23, and the left end of the locking screw I 24 is in contact with the right side of the guide rod 22, and the fixing block 25 is connected to the lower rear side of the sleeve 23. The rotating block 26 is rotatably connected to the upper rear side of the sliding sleeve 23. A handle is also provided on the rotating block 26 to facilitate manual control of the rotation of the rotating block 26.

The upper and lower corresponding conductive sheets 28 contact each other to form a complete cylinder to wrap and clamp the end of the electric fuse.

[0033] like Fig. 9 As shown, a shoulder strap 29 is also included. The shoulder strap 29 is connected to the right side of the top surface of the fixing tube 2. By manually hanging the shoulder strap 29 diagonally on the shoulder, the device can be transferred more conveniently.

[0034] like Fig. 9 and Fig.10 As shown, it also includes a scale block 30, a T-shaped block 32, a baffle 33 and a locking screw II 34. The scale block 30 is symmetrically and evenly spaced at front and back on the left side of the lower part of the support frame 1, and the lower part of the support frame 1 is symmetrically opened with T-shaped slots 31. T-shaped blocks 32 are slidably connected in the two T-shaped slots 31. The baffle 33 is connected to the left side of the T-shaped block 32. The locking screw II 34 is threadedly connected to the T-shaped block 32, and the bottom end of the locking screw II 34 is in contact with the support frame 1.

[0035] When it is necessary to pre-embed the electric fuse at the port of the carat tube, first, the electric fuse is sleeved to the middle position of the outer side of the arc plate 8, and then the sliding sleeve 23 is moved up and down according to the end height of the electric fuse, driving the fixed block 25 and the rotating block 26 to move up and down to adjust the height, and then tightening the locking screw Ⅰ24 to fix the position of the sliding sleeve 23, the fixed block 25 and the rotating block 26, and then the rotating block 26 is rotated upward to open, and the torsion spring 27 is deformed, and then the end of the electric fuse is placed between the fixed block 25 and the rotating block 26, and then the rotating block 26 is loosened, and the torsion spring 27 is restored to its original state, which can drive The rotating block 26 is rotated downward to reset, so that the fixed block 25 and the rotating block 26 clamp the end of the electric fuse to fix the position of the electric fuse, and the conductive sheet 28 can contact the end of the electric fuse. The conductive sheet 28 is used for external power supply; then according to the distance between the pre-buried position of the electric fuse and the right end of the carat tube, the T-shaped block 32 is moved left and right, and the T-shaped block 32 can drive the baffle 33 to move left and right. According to the left side of the baffle 33 and the scale displayed on the scale block 30, the position of the baffle 33 can be adjusted, and then the locking screw II 34 is tightened to fix the position of the baffle 33; then the device is Move to the right end of the carat tube, so that the wiping sponge 9 is located at the right end of the inner wall of the carat tube, and then inject air into the air bag 17 on the left through the air pump 18 on the left and the connecting pipe 19 on the left, so that the air bag 17 on the left expands, and the air bag 17 on the left squeezes the guide rail 5 on the left to move away from the rotating cylinder 3, so that the telescopic rod 4 on the left is extended, and the connecting spring 6 on the left is stretched. The guide rail 5 on the left can drive the sliding frame 7 and the wiping sponge 9 on the left to move away from the rotating cylinder 3, so that the wiping sponge 9 contacts the right end of the inner wall of the carat tube, and then is driven by the driving motor 13 The driving gear 14 rotates, which can drive the driven gear ring 15 and the rotating cylinder 3 to rotate, thereby driving the wiping sponge 9 to rotate to wipe the right end of the inner wall of the carat tube, which is convenient for the subsequent pre-embedding of the electric fuse; then the electric control valve 20 on the left side is opened, the air inside the left airbag 17 can be discharged, the left airbag 17 will shrink and recover, and the left connecting spring 6 can recover to its original state, driving the left guide rail 5, the left sliding frame 7 and the wiping sponge 9 to move and reset in the direction close to the rotating cylinder 3, and the left telescopic rod 4 is shortened and recovered, so that the wiping sponge 9 is separated from the right end of the inner wall of the carat tube;Then the whole device is moved to the left until the left side of the baffle plate 33 contacts the right end of the carat tube, and the pre-embedded position of the electric fuse can be determined. Similarly, by controlling the expansion of the airbag 17 on the right side, the arc plate 8 can be driven to move in a direction away from the rotating cylinder 3. When the arc plate 8 contacts the electric fuse, the arc plate 8 can expand the electric fuse (the initial shape of the electric fuse is wavy), so that the electric fuse fits the right end of the inner wall of the carat tube, and then the conductive sheet 28 is controlled to be energized so that the electric fuse can be energized to heat and melt the right end of the inner wall of the carat tube. At this time, the arc plate 8 can be controlled to continue to move in a direction away from the rotating cylinder 3, so that the electric fuse can be pressed into the right end of the inner wall of the carat tube to complete the pre-embedded work of the electric fuse, and then the conductive sheet 28 is controlled to be de-energized, and then the rotating cylinder 3 is controlled to rotate. The rotating cylinder 3 can drive the arc plate 8 to rotate to smooth the right end of the inner wall of the carat tube. Due to the material of the arc plate 8 The polytetrafluoroethylene is used, so the melted pipe part at the end of the carat tube will not adhere to the surface of the arc plate 8, and the end of the electric fuse is clamped by the fixed block 25 and the rotating block 26, so the electric fuse will not rotate with the arc plate 8, thereby not affecting the pre-embedding of the electric fuse. Finally, the air bag 17 on the right side is controlled to shrink and recover, which can drive the arc plate 8 to move in the direction close to the rotating cylinder 3, so that the arc plate 8 is separated from the inner wall of the carat tube. Repeat the above operation to complete the pre-embedding of the electric fuse in batches, and for the same type of carat tube, the height of the sliding sleeve 23 and the position of the baffle 33 do not need to be readjusted, which can improve the pre-embedding efficiency of the electric fuse; for different types of carat tubes, the sliding frame 7 can be pulled to the right along the guide rail 5 by compressing the reset spring 11 to remove it, so that the sliding block 10 is separated from the card slot 12, and then the sliding frame 7 of different specifications and sizes can be replaced for use. ;

[0036] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
