Description

Technical Field

[0001] This utility model relates to the field of pipeline processing technology, specifically a pipeline end sealing device. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas in pipelines. They can also be transported using their own pressure or gravity. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] Chinese patent application CN 216065227 U discloses a pipe sealing machine, including a frame, a power mechanism and a sealing mechanism disposed inside the frame, and a control box. A base mounting plate is disposed on the upper surface of the frame, and a mounting box is disposed on the upper surface of the base mounting plate. A clamping mechanism is disposed on one side of the mounting box. The power mechanism consists of a motor and a rotating pulley disposed inside the mounting box. An output pulley is disposed at the output end of the motor, and the output pulley is connected to the rotating pulley by a belt. The sealing mechanism includes a fixed seat, a mounting frame, a sealing shaft, and a hydraulic cylinder. The fixed seat is disposed on the upper surface of the mounting plate and located on one side of the mounting box. The mounting frame is mounted on the upper end of the fixed seat by a pin, and the sealing shaft is disposed in the middle of the mounting frame.

[0004] The aforementioned pipe sealing machine uses a sealing mold to squeeze the rotating pipe and uses the heat generated by the squeezing to seal the pipe end. However, in actual use, the sealing shaft and rotating pulley of the aforementioned pipe sealing machine are in fixed positions, and it can only seal pipe ends in the same direction. Its mobility is poor, and it cannot seal pipes of different models, which greatly reduces the applicable scope of the aforementioned pipe sealing machine. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe end sealing device to solve the problem of the above-mentioned pipe sealing machine, which uses a sealing mold to squeeze the pipe during rotation and uses the heat generated by the squeezing to seal the pipe end; however, in actual use, the sealing shaft and rotating pulley of the above-mentioned pipe sealing machine are in fixed positions, and can only perform sealing operations on pipe ends in the same direction. Its mobility is poor, and it cannot seal pipes of different models, which greatly reduces the applicability of the above-mentioned pipe sealing machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A pipe end sealing device includes a conveying channel, which is annular in shape, and a fixed seat is sleeved on the outer side of the conveying channel; the bottom two sides of the fixed seat are fixedly connected to a bracket by bolts; a sliding component is slidably connected to the top center of the fixed seat, and a hydraulic cylinder is fixedly connected to the end of the sliding component away from the fixed seat by bolts; a pressure block is welded to the telescopic rod of the hydraulic cylinder. A friction wheel is provided below the hydraulic cylinder one, and a sliding member two is rotatably connected to one side of the friction wheel; a slide rail one is slidably connected to both sides of the bottom of the sliding member two; a hydraulic cylinder two is fixedly connected to the side of the sliding member two away from the conveying channel.

[0007] As a further technical solution of this utility model, the bottom of both slide rails is welded to the top sides of the rotating component; a roller is welded to the bottom of the rotating component away from the two slide rails.

[0008] As a further technical solution of this utility model, a connecting seat is sleeved on the outer side of the roller shaft, and both sides of the connecting seat are fixedly connected to the bracket by bolts.

[0009] As a further technical solution of this utility model, a gear is welded to the bottom of the roller shaft, and the gear meshes with a rack.

[0010] As a further technical solution of this utility model, a hydraulic cylinder three is welded to the end of the rack away from the gear, and both ends of the bottom of the hydraulic cylinder three are welded to the base. The rack has two slide rails symmetrically welded to its bottom; the bottom of each slide rail is slidably connected to a sliding member, the bottom of which is welded to the base.

[0011] As a further technical solution of this utility model, both ends of the base are fixedly connected to the bracket by bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In use, the pipe to be sealed is placed inside the conveying channel and extended to the other end of the conveying channel and one side of the friction wheel. Under the friction force generated by the rotation of the friction wheel, the pipe end will soften due to heat. When the pipe end can deform due to external influences, the pressure block controlled by the hydraulic cylinder one is used to squeeze the pipe end, so that the pipe end is squeezed and fits together, thereby achieving the purpose of sealing the pipe end. Depending on the pipe model, the position of the hydraulic cylinder one can be adjusted by the sliding part one. The position of the friction wheel can also be adjusted by the sliding part two sliding on the two slide rails one through the hydraulic cylinder two. The sliding part one and the hydraulic cylinder two of this device greatly increase the mobility of the device, enabling sealing operations on pipes of different models, and greatly increasing the applicability of the device. This invention uses a hydraulic cylinder to control the movement of a rack. As the rack moves, it causes the gear meshing with it to rotate. When the gear rotates, it synchronously drives the roller to rotate, which in turn drives the rotating component to rotate. The friction wheel, sliding component two, and hydraulic cylinder two, which are fixedly connected to the rotating component, can rotate synchronously with the rotating component. When sealing a pipe, for pipes with irregular end shapes, the above actions can change the position of the friction wheel relative to the pipe end, facilitating friction and heat generation by the friction wheel on the pipe, and further increasing the mobility of the device. In this invention, the two sliding parts 3 and the slide rail 2 at the bottom of the rack make the rack move more smoothly, reduce the pressure generated by the hydraulic cylinder 3 pushing the rack, and extend the service life of the rack.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 In this embodiment of the utility model, a pipe end sealing device includes a conveying channel 1, which is annular in shape. A fixed seat 2 is sleeved on the outer side of the conveying channel 1. The bottom two sides of the fixed seat 2 are fixedly connected to the bracket 17 by bolts. A sliding member 4 is slidably connected to the top center of the fixed seat 2. A hydraulic cylinder 3 is fixedly connected to the end of the sliding member 4 away from the fixed seat 2 by bolts. A pressure block is welded on the telescopic rod of the hydraulic cylinder 3. Below the hydraulic cylinder 3, there is a friction wheel 5, and a sliding member 6 is rotatably connected to one side of the friction wheel 5; a slide rail 8 is slidably connected to both sides of the bottom of the sliding member 6; a hydraulic cylinder 7 is fixedly connected to the side of the sliding member 6 away from the conveying channel 1.

[0021] By adopting the above technical solution, during use, the pipe to be sealed is placed inside the conveying channel 1, and the pipe is extended to the other end of the conveying channel 1 and one side of the friction wheel 5. Under the friction force generated by the rotation of the friction wheel 5, the pipe end will soften due to heat. When the pipe end can deform due to external influences, the pressure block is controlled by the hydraulic cylinder 3 to squeeze the pipe end, so that the pipe end is squeezed and fits together, thereby achieving the purpose of sealing the pipe end. Depending on the pipe model, the position of the hydraulic cylinder 3 can be adjusted by the sliding part 4. The position of the friction wheel 5 can also be adjusted by the sliding part 6 sliding on the two slide rails 8 through the hydraulic cylinder 7. The sliding part 4 and the hydraulic cylinder 7 of this device greatly increase the mobility of this device, enabling sealing operations on pipes of different models, and greatly increasing the applicability of this device.

[0022] In this embodiment, the bottom of both slide rails 8 is welded to the top sides of the rotating component 9; a roller 10 is welded to the rotating component 9 away from the bottom of the two slide rails 8. A connecting seat 11 is sleeved on the outer side of the roller 10, and both sides of the connecting seat 11 are fixedly connected to the bracket 17 by bolts. A gear 12 is welded to the bottom of the roller 10, and the gear 12 meshes with a rack 13.

[0023] By adopting the above technical solution, the rack 13 is moved by the hydraulic cylinder 14. While the rack 13 is moving, the gear 12 meshing with it can rotate. When the gear 12 rotates, it can synchronously drive the roller 10 to rotate. The roller 10 then synchronously drives the rotating component 9 to rotate. The friction wheel 5, the sliding component 6, and the hydraulic cylinder 7, which are fixedly connected to the rotating component 9, can rotate synchronously with the rotating component 9. When sealing the pipe, for pipes with irregular end shapes, the above actions can change the position of the friction wheel 5 and the pipe end, making it easier for the friction wheel 5 to generate heat by friction on the pipe, and further increasing the mobility of the device.

[0024] In this embodiment, a hydraulic cylinder 14 is welded to the end of the rack 13 away from the gear 12, and both ends of the bottom of the hydraulic cylinder 14 are welded to the base 16. The bottom of the rack 13 is symmetrically welded with two slide rails 15; the bottom of both slide rails 15 is slidably connected to the sliding member 18, and the bottom of the sliding member 18 is welded to the base 16. Both ends of the base 16 are fixedly connected to the bracket 17 by bolts.

[0025] By adopting the above technical solution, the two sliding parts 18 and the slide rail 15 at the bottom of the rack 13 can make the rack 13 move more smoothly, reduce the pressure generated by the hydraulic cylinder 14 pushing the rack 13, and extend the service life of the rack 13.

[0026] The working principle of this utility model is as follows: When in use, the pipe to be sealed is placed inside the conveying channel 1, and the pipe is extended to the other end of the conveying channel 1 and one side of the friction wheel 5. Under the friction force generated by the rotation of the friction wheel 5, the end of the pipe will soften due to heat. When the end of the pipe can be deformed due to external influences, the pressure block is controlled by the hydraulic cylinder 3 to squeeze the end of the pipe, so that the end of the pipe is squeezed and fits together, thereby achieving the purpose of sealing the end of the pipe. Depending on the type of pipe, the position of the hydraulic cylinder 3 can be adjusted by the sliding part 4. The position of the friction wheel 5 can also be adjusted by the sliding part 6 sliding on the two slide rails 8 through the hydraulic cylinder 7. The sliding part 4 and the hydraulic cylinder 7 of this device greatly increase the mobility of this device, enabling sealing operations on pipes of different types, and greatly increasing the applicability of this device. As a further optimization, the rack 13 is moved by the hydraulic cylinder 14. While the rack 13 is moving, the gear 12 meshing with it can rotate. When the gear 12 rotates, it can synchronously drive the roller 10 to rotate. The roller 10 then synchronously drives the rotating component 9 to rotate. The friction wheel 5, the sliding component 6, and the hydraulic cylinder 7, which are fixedly connected to the rotating component 9, can rotate synchronously with the rotating component 9. When sealing the pipe, for pipes with irregular end shapes, the above actions can change the position of the friction wheel 5 and the pipe end, making it easier for the friction wheel 5 to generate heat by friction on the pipe, and further increasing the mobility of the device. The two sliding parts 18 and the slide rail 15 at the bottom of the rack 13 make the rack 13 move more smoothly, reduce the pressure generated by the hydraulic cylinder 14 pushing the rack 13, and extend the service life of the rack 13.
