Description
Technical Field
[0001] The utility model belongs to the technical field of automatic firing of heat shrinkable sleeves, and particularly relates to an automatic firing device for heat shrinkable sleeves of bent steel-plastic conversion pipes. Background Art
[0002] Pipes for transporting fluids such as natural gas are usually metal pipes and plastic pipes. Due to different fluid pressures, pipes of corresponding materials need to be used in different pipeline sections for transportation, so there is a need to switch between metal pipes and plastic pipes, and thus steel-plastic conversion pipes are required; the steel-plastic conversion pipe is a steel pipe wrapped with a heat shrinkable anti-corrosion material, that is, a heat shrinkable sleeve; the heat shrinkable sleeve is a heat shrinkable anti-corrosion material sleeved outside the steel pipe, and the heat shrinkable sleeve is composed of a radiation-crosslinked polyolefin substrate and a special sealing hot melt adhesive.
[0003] Generally, when heating the heat shrinkable sleeve on the outer surface of the steel-plastic conversion pipe, manual heating is required. In the case of manual heating, since manual baking cannot ensure uniform heating of each position of the heat shrinkable sleeve, some positions will not be tightened, and then the pressure at the untightened positions of the steel-plastic conversion pipe will be different, resulting in potential hazards. Summary of the Utility Model
[0004] The purpose of the utility model is to provide an automatic firing device for heat shrinkable sleeves of bent steel-plastic conversion pipes. By starting the motor, the rotating shaft drives the first pulley to rotate, and at the same time, it moves on the sliding rod, driving the baking device to move slowly, and uniformly baking the heat shrinkable sleeve on the bent pipe, solving the problem that in the case of existing manual heating, since manual baking cannot ensure uniform heating of each position of the heat shrinkable sleeve, some positions will not be tightened, and then the pressure at the untightened positions of the steel-plastic conversion pipe will be different, resulting in potential hazards.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model relates to an automatic firing device for a bent - tube steel - plastic conversion heat - shrinkable sleeve, which includes a bottom plate.

A rotating shaft is fixedly connected to the left output end of the motor. A first pulley is fixedly connected to the left side of the rotating shaft. A first gear is fixedly connected to the left side of the first pulley. The bottom of the first pulley is in contact with a sliding rod. By setting the sliding rod, specifically, when the motor starts, the rotating shaft drives the first pulley to rotate, and at the same time, it moves on the sliding rod, driving the baking device to move slowly, uniformly baking the heat - shrinkable sleeve on the bent tube, so that the heat - shrinkable sleeve uniformly wraps around the bent tube, making the device more convenient to use and reducing the risk of workers being scalded during work.
[0007] Further, a runner is rotatably connected to the left side of the baking device through a pin shaft. The bottom of the runner is in contact with a slideway.

[0009] Further, a second fixing block is fixedly connected to the back of the first fixing plate. A fixing rod is arranged on the left side of the second fixing block. A limiting plate is fixedly connected to the top of the fixing rod. A third pulley is rotatably connected to the bottom of the limiting plate through a pin shaft. The number of the limiting plates is two, and the two limiting plates are symmetrically arranged with the fixing rod as the center. The setting of the limiting plates can limit the third pulley to prevent it from deviating or falling off.
[0010] Further, a moving groove is formed on the left side of the second fixed block. A spring is fixedly connected to the right side of the inner wall of the moving groove. A moving block is fixedly connected to the left side of the spring. A limiting block is fixedly connected to the back of the moving block. The number of the limiting blocks is two, and the two limiting blocks are symmetrically arranged with the moving block as the center. The left side of the moving block is fixedly connected to the right side of the fixed rod. By providing the moving groove, specifically when the two pulleys III come into contact with the bent pipe, the moving block moves into the moving groove. At the same time, due to the arrangement of the spring, the two pulleys III clamp the bent pipe, which can not only prevent the bent pipe from shaking during baking, causing the heat shrinkable sleeve to touch the heating part of the baking device and resulting in damage, but also play a clamping effect, and at the same time facilitate the taking of the bent pipe.
[0011] Further, the number of the fixing pieces is two, and the two fixing pieces are symmetrically arranged with the first fixed block as the center. The number of the bent pipes is several, and the several bent pipes are arranged in a horizontal array. A limiting hole is formed on the front surface of the first fixing plate. The slideway formed on the right side of the fixing piece can make the runner run more smoothly inside it, avoiding the phenomenon of jamming.
[0012] The utility model has the following beneficial effects:
[0013] 1. By providing the sliding rod, specifically, when the motor is started, the rotating shaft drives the pulley I to rotate, and at the same time, it moves on the sliding rod, driving the baking device to move slowly, uniformly baking the heat shrinkable sleeve on the bent pipe, so that the heat shrinkable sleeve is evenly wrapped on the bent pipe. The device is more convenient to use, and at the same time reduces the risk of the staff being scalded during work.
[0014] 2. By providing the moving groove, specifically when the two pulleys III come into contact with the bent pipe, the moving block moves into the moving groove.

A fixing piece 13 is arranged on the left side of the first fixing block 12. A first fixing plate 14 is fixedly connected to the back of the fixing piece 13. A bent pipe 15 is in contact with the top of the first fixing block 12. A baking device 2 is arranged above the bent pipe 15. A motor 3 is arranged on the back of the baking device 2. A rotating shaft 313 is fixedly connected to the left output end of the motor 3. A first pulley 31 is fixedly connected to the left side of the rotating shaft 313. A first gear 311 is fixedly connected to the left side of the first pulley 31. The bottom of the first pulley 31 is in contact with a sliding rod 34. By setting the sliding rod 34, specifically, when the motor 3 starts, the rotating shaft 313 drives the first pulley 31 to rotate, and at the same time, it moves on the sliding rod 34, driving the baking device 2 to move slowly, uniformly baking the heat shrinkable sleeve on the bent pipe 15, so that the heat shrinkable sleeve evenly wraps around the bent pipe 15. The device is more convenient to use, and at the same time reduces the risk of workers being scalded during work.
[0026] The left side of the baking device 2 is rotatably connected to a runner 21 through a pin shaft. The bottom of the runner 21 is in contact with a slideway 22. A limiting ring 23 is fixedly connected to the top of the first fixing block 12. A fixing column 231 is arranged at the center of the limiting ring 23. The bottom of the fixing column 231 is fixedly connected to the top of the first fixing block 12.
[0027] The bottom of the first gear 311 is meshed with a second gear 312. A second pulley 32 is fixedly connected to the right side of the second gear 312. The top of the second pulley 32 is in contact with the bottom of the sliding rod 34. A second fixing plate 33 is arranged on the left side of the sliding rod 34. The front of the second fixing plate 33 is fixedly connected to the back of the baking device 2.
[0028] A second fixing block 4 is fixedly connected to the back of the first fixing plate 14. A fixing rod 41 is arranged on the left side of the second fixing block 4. A limiting plate 42 is fixedly connected to the top of the fixing rod 41. A third pulley 43 is rotatably connected to the bottom of the limiting plate 42 through a pin shaft. The number of the limiting plates 42 is two, and the two limiting plates 42 are symmetrically arranged with the fixing rod 41 as the center.
[0029] A second fixed block 4 is provided with a moving groove 5 on the left side. On the right side of the inner wall of the moving groove 5, a spring 51 is fixedly connected. On the left side of the spring 51, a moving block 52 is fixedly connected. On the back of the moving block 52, a limiting block 521 is fixedly connected. The number of the limiting blocks 521 is two, and the two limiting blocks 521 are symmetrically arranged with the moving block 52 as the center. The left side of the moving block 52 is fixedly connected to the right side of the fixed rod 41. By providing the moving groove 5 in this utility model, specifically when the two third pulleys 43 come into contact with the bent pipe 15, the moving block 52 moves into the interior of the moving groove 5. At the same time, due to the arrangement of the spring 51, the two third pulleys 43 clamp the bent pipe 15, which can not only prevent the bent pipe 15 from shaking during baking, resulting in the shrinkage sleeve touching the heating part of the baking device 2 and causing damage, but also play a clamping role, and at the same time facilitate the taking of the bent pipe 15.
[0030] The number of the fixing pieces 13 is two, and the two fixing pieces 13 are symmetrically arranged with the first fixed block 12 as the center. The number of the bent pipes 15 is several, and the several bent pipes 15 are arranged in a horizontal array. A limiting hole is provided on the front surface of the first fixing plate 14.
[0031] A specific application of this embodiment is as follows: The bent pipe 15 is placed into the limiting hole provided on the front surface of the first fixing plate 14 through the heating hole of the baking device 2. After being placed, the two third pulleys 43 will enable the bent pipe 15 to move smoothly. And due to the spring 51 provided inside the second fixed block 4, the two third pulleys 43 play a clamping role on the bent pipe 15, preventing the shrinkage sleeve from being damaged due to shaking during baking. At the same time, it is used in combination with the limiting ring 23 and the fixed column 231 to prevent the bent pipe 15 from deflecting left and right. By starting the motor 3, the rotating shaft 313 drives the first pulley 31 to rotate. Since a first gear 311 is fixed on the right side of the first pulley 31, the first gear 311 can drive the second gear 312 to rotate simultaneously. The second gear 312 will drive the second pulley 32 to move synchronously. Since the first pulley 31 and the second pulley 32 clamp the sliding rod 34, the synchronous movement of the first pulley 31 and the second pulley 32 can move on the sliding rod 34, and at the same time drive the baking device 2 to move. Since the rotating wheels 21 are provided on both the left side and the right side of the baking device 2, the baking device 2 moves more smoothly during movement, and at the same time, the gravity influence on the first pulley 31 and the second pulley 32 can be reduced. The baking device 2 moves slowly along the track of the sliding rod 34 to bake the shrinkage sleeve on the outer surface of the bent pipe 15, so that it can be evenly wrapped on the bent pipe 15, making the device more convenient to use, and at the same time reducing the risk of the staff being scalded during work.
