Description

Technical Field

[0001] The present invention relates to the technical field of pipeline connection, and particularly to an intelligent socket-type pipeline connection device. Background Technique

[0002] Socket connection, also known as socket joint connection, is a pipeline connection method in which the end of one pipeline is inserted into the interior of another pipeline, and the two pipelines are closely connected through a sealing material or a specific device. Its structure is simple. Since socket connection does not require complex connecting parts and can be completed only through the shape and size of the pipeline itself, it greatly reduces the installation difficulty and cost. In order to improve the stability of socket connection, usually two clamps are required to clamp the two sections of pipelines to be socket-connected, and then one pipeline is driven to be inserted into the other pipeline to complete the socket connection work of the pipelines. As a common pipeline connection auxiliary tool, the socket-type pipeline connection device is widely used in pipeline connection work in multiple fields such as water supply and drainage, gas, heat, and electricity. In the operation process of the existing socket-type pipeline connection devices, most of them use hydraulic cylinders as the driving source, and the pipelines are driven to move through the clamps to complete the socket work of the pipelines. However, in the specific operation process, generally, the socket distance of the pipelines needs to be controlled, and relying solely on the hydraulic cylinder cannot accurately control the socket distance of the pipelines, resulting in the socket distance of the pipelines not meeting the specified requirements. For this reason, we propose an intelligent socket-type pipeline connection device. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, a steel belt is tied to one end of the insertion tube. Then, during the process of the sliding frame driving the insertion tube to move, the outer wall of the sleeve squeezes the steel belt. At this time, the steel belt drives the mounting rod and the sleeve rod to move towards the docking rod through the telescopic rod. When the sleeve rod abuts against the docking rod, it will squeeze the docking rod, causing the docking rod to abut against the button of the controller. When the button of the controller is squeezed, the controller can cut off the power supply of the device, thereby stopping the movement of the sliding frame. In this way, it is ensured that after the insertion tube moves to the specified distance, it can immediately stop moving, greatly improving the control of the pipe socket insertion distance of the device and solving the problem that a single hydraulic cylinder cannot accurately control the socket insertion distance; During the process of the steel belt being squeezed and moving by the sleeve in the present invention, the steel belt drives the scraper to move, and the scraper scrapes off the gravel attached to the outer surface of the insertion tube. After the gravel is scraped off, it will slide down to the bottom of the steel belt through the outer surface of the insertion tube and the inner wall of the steel belt, and finally be discharged from the dust outlet. This can solve the problem that after the insertion tube is inserted into the sleeve, a large amount of gravel adheres to the outer surface of the part located inside the sleeve, thereby affecting the socket insertion stability between the insertion tube and the sleeve, and effectively improving the socket insertion connection stability of the device; According to the specific socket insertion distance in the present invention, turn the screw rod to separate the rubber pad from the mounting rod. At this time, the sleeve rod and the mounting rod can be manually retracted, and the scale groove pointed by the indicator plate is used to match the required socket insertion distance. During the movement of the indicator plate, the cooperation of the clamping plate and the scale groove can make the pointing of the indicator plate more accurate and improve the accuracy of the retraction distance of the sleeve rod. Then, turn the screw rod in the reverse direction to make the rubber pad fit with the mounting rod, thereby completing the limiting work between the mounting rod and the sleeve rod. At this time, the distance between the sleeve rod and the docking rod is the same as the length of the actual required socket insertion distance. When the insertion tube enters the sleeve by a specified distance, the sleeve rod can abut against the docking rod, thereby realizing the power-off operation and stopping the movement of the insertion tube, effectively improving the auxiliary function of the device for socket insertion connection work.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-13, the present invention provides a technical solution: a socket-type pipe intelligent connection device, including a load-bearing frame 1. Inside the load-bearing frame 1, a sleeve 11 and an insertion pipe 12 are respectively placed. The inner diameter of the sleeve 11 is larger than the outer diameter of the insertion pipe 12. When connecting, by inserting the insertion pipe 12 into the sleeve 11, the connection work between the insertion pipe 12 and the sleeve 11 is completed. A fixed frame 2 is fixedly connected to one side of the load-bearing frame 1 close to the sleeve 11. A sliding frame 21 is slidably connected to one side of the load-bearing frame 1 close to the insertion pipe 12. Clamping arms 25 are rotatably connected to both sides of the fixed frame 2 and the sliding frame 21. Hydraulic cylinders A 22 are rotatably connected to the tops of the fixed frame 2 and the sliding frame 21. Transmission frames 23 are rotatably connected to the tops of the fixed frame 2 and the sliding frame 21. The output end of the hydraulic cylinder A 22 is rotatably connected to the transmission frame 23 on its same side. Connecting frames 24 are rotatably connected to the top and bottom of the transmission frame 23. The top of the clamping arm 25 is rotatably connected to the connecting frame 24 on its same side through a shaft rod. Due to its relatively wide structure, when clamping the sleeve 11 and the insertion pipe 12, the contact surface between the clamping arm 25 and the sleeve 11 and the insertion pipe 12 becomes larger, so that the alignment work of the sleeve 11 and the insertion pipe 12 can be automatically completed without the need to additionally align the sleeve 11 and the insertion pipe 12, improving the pipe intelligent connection effect of the device. Guide wheels 211 are rotatably connected to both sides of the top of the sliding frame 21. The guide wheels 211 are in contact with the top of the load-bearing frame 1. A control console 212 is fixedly connected to one side of the sliding frame 21 close to the fixed frame 2. A control cabinet 3 is fixedly connected to one side of the top of the load-bearing frame 1 far from the fixed frame 2. A power supply and control components are arranged inside the control cabinet 3. The power supply can supply power to the electrical appliances on the device. By cooperating the control components with the control console 212, relevant operations can be performed on the device. Hydraulic cylinders B 31 are fixedly connected to both sides of the bottom of the control cabinet 3. The output end of the hydraulic cylinder B 31 is rotatably connected to the sliding frame 21.

[0019] Further, when connecting pipes, the hydraulic cylinders A 22 on the fixed frame 2 and the sliding frame 21 are started through the control console 212. The hydraulic cylinders A 22 drive the transmission frames 23 to rotate. During the rotation of the transmission frames 23, the connecting frames 24 at both ends can be pushed to rotate, so that the two clamping arms 25 are closed to each other. At this time, the fixed frame 2 and the sliding frame 21 can respectively clamp the sleeve 11 and the insertion pipe 12 through the clamping arms 25. Then, the hydraulic cylinder B 31 is started to push the sliding frame 21 to move towards the fixed frame 2. During this process, the sliding frame 21 drives the insertion pipe 12 to insert into the sleeve 11 through the clamping arms 25, and the pipe connection work can be completed.

[0020] Combined with the attached Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 11 and Figure 12As shown in the figure, on one side of the sliding carriage 21 close to the fixed frame 2, there is a fixedly connected mounting housing 4. On one side of the mounting housing 4, there is a limit port A41. A telescopic rod 5 is slidably connected in the limit port A41. The bottom end of the telescopic rod 5 is fixedly connected with a steel belt 6. A number of evenly distributed balls 61 are arranged on the inner wall of the steel belt 6. On one side of the steel belt 6 close to the sleeve 11, there is a fixedly connected scraper 62. A dust falling port 63 is opened at the bottom of the steel belt 6. On one side of the top of the steel belt 6, there is a rotatably connected limit frame 64. One end of the limit frame 64 far from the steel belt 6 is threadedly connected with a screw rod 65. One end of the steel belt 6 far from the limit frame 64 is fixedly connected with a limit block 66. A threaded hole is opened on the limit block 66, which can be used to insert the screw rod 65 into the limit block 66. In this way, through the cooperation of the limit frame 64, the screw rod 65 and the limit block 66, the two ends of the steel belt 6 are limited, so that the balls 61 just fit on the outer wall of the insertion tube 12. On one side of the telescopic rod 5 close to the mounting housing 4, there is a fixedly connected mounting frame 51 through the limit port A41. On the inner wall of the mounting housing 4 on the side close to the sliding carriage 21, there is a fixedly connected controller 52. The controller 52 is connected to the hydraulic cylinder B31 through an electric wire. Buttons are arranged on the controller 52. By pressing the buttons, the controller 52 can cut off the power supply of the hydraulic cylinder B31, so as to stop the movement of the insertion tube 12. A partition plate 7 is fixedly connected in the mounting housing 4. An installation hole 71 is opened on the partition plate 7. A docking rod 73 is slidably connected in the installation hole 71. One end of the docking rod 73 is aligned with the button of the controller 52. On one side of the mounting frame 51 close to the docking rod 73, there is a fixedly connected mounting rod 8. One end of the mounting rod 8 close to the docking rod 73 is slidably sleeved with a sleeve rod 81. The sleeve rod 81 and the docking rod 73 are in contact with each other.

[0021] Further, before the pipeline connection, the steel belt 6 is attached to the outer wall of the insertion pipe 12 near one end of the sleeve 11, and it is ensured that the scraping plate 62 is aligned with the end of the insertion pipe 12. Then, the limit frame 64 is rotated, and the limit frame 64 is sleeved on the limit block 66. Then, the screw rod 65 is rotated to insert the screw rod 65 into the limit block 66 to limit the steel belt 6. Then, when the insertion pipe 12 is inserted into the sleeve 11, the outer wall of the sleeve 11 will squeeze the scraping plate 62, so that the scraping plate 62 and the steel belt 6 move along the outer wall of the insertion pipe 12. During this process, the scraping plate 62 can clean the sand and gravel attached to the outer wall of the insertion pipe 12 and collect it in the steel belt 6. After the sand and gravel are scraped off, they will slide down along the steel belt 6 and finally be discharged through the dust fall port 63, ensuring that a large amount of sand and gravel will not be attached to the outer wall of the insertion pipe 12, affecting the seal after the insertion pipe 12 and the sleeve 11 are connected. During the movement of the steel belt 6, the telescopic rod 5 will drive the mounting rod 8 and the sleeve rod 81 to move towards the docking rod 73. When the sleeve rod 81 abuts against the docking rod 73, it will squeeze the docking rod 73, causing it to pass through the mounting hole 71 and dock with the button of the controller 52. At this time, the hydraulic cylinder B31 can be controlled to close through the controller 52, so that the sliding frame 21 and the insertion pipe 12 stop moving, so that the staff can more accurately control the distance of the insertion pipe 12 inserted into the sleeve 11.

[0022] Combined with the attached Figure 6 , Figure 7 and Figure 13 As shown, a limit groove 72 is formed on the partition plate 7, the mounting hole 71 is located in the limit groove 72, and a fixing spring 74 is fixedly connected between the end of the docking rod 73 far from the controller 52 and the inner wall of the limit groove 72. The fixing spring 74 is sleeved on the outer side of the docking rod 73. A plurality of limit plates 75 are fixedly connected to the side of the partition plate 7 far from the controller 52, and the plurality of limit plates 75 are evenly distributed around the limit groove 72.

[0023] Further, after the docking rod 73 is squeezed by the sleeve rod 81 and moves towards the controller 52, the docking rod 73 will cooperate with the limiting groove 72 to squeeze the fixing spring 74, causing the fixing spring 74 to contract. A steel plate is provided at the end of the docking rod 73 away from the controller 52. When the docking rod 73 squeezes the button of the controller 52 to a certain extent, the steel plate on the docking rod 73 will contact the limiting plate 75. At this time, through the cooperation of multiple limiting plates 75 and the steel plate, the docking rod 73 is limited, avoiding the problem that the controller 52 is damaged due to excessive force of the docking rod 73 squeezing the button of the controller 52. After the connection work of the sleeve 11 and the insertion tube 12 is completed, the screw rod 65 is rotated reversely to separate the screw rod 65 from the limiting block 66. At this time, the limiting frame 64 is lifted, so that the two ends of the steel belt 6 are released from the limit, and the steel belt 6 is removed from the insertion tube 12. At this time, the limiting effect caused by the steel belt 6 being tied to the insertion tube 12 disappears, and the fixing spring 74 starts to rebound, driving the docking rod 73 back to its original position, facilitating repeated operations next time.

[0024] Combined with the attached Figure 5 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10 As shown, a limiting port B42 is opened at the top of the installation shell 4. A number of uniformly distributed scale grooves 43 are opened at the top of the installation shell 4. A number of scale grooves 43 are all located on one side of the limiting port B42. A limiting spring 82 is fixedly connected between the installation rod 8 and the inner wall of the sleeve rod 81. A connecting pipe 83 is fixedly connected to the top of the sleeve rod 81. The connecting pipe 83 is located in the limiting port B42. A screw rod 84 is threadedly connected in the connecting pipe 83. A rubber pad 85 is fixedly connected to the bottom end of the screw rod 84. A knob 86 is fixedly connected to the top end of the screw rod 84. An indicating plate 9 is fixedly connected to one side of the connecting pipe 83 close to the scale groove 43. An installation groove 91 is opened at the bottom of the indicating plate 9. A clamping plate 92 is slidably connected in the installation groove 91. The bottom of the clamping plate 92 is of an arc-shaped structure. The bottom of the clamping plate 92 is clamped in the scale groove 43 corresponding to its current position. A number of installation springs 93 are fixedly connected between the top of the clamping plate 92 and the inner top wall of the installation groove 91.

[0025] Further, when performing pipeline connection work, first determine the distance that the insertion tube 12 needs to be inserted into the sleeve 11. Then, turn the screw rod 84 by rotating the knob 86 to separate the rubber pad 85 from the mounting rod 8. Then, through the cooperation of the screw rod 84 and the connecting pipe 83, manually move the sleeve rod 81 to make it contract towards the mounting rod 8. At this time, the limit spring 82 will contract due to the pressure it receives. At this time, the connecting pipe 83 will drive the indicator plate 9 to move together. During the movement of the indicator plate 9, since the bottom of the clamping plate 92 is stuck in the scale groove 43, during the movement of the indicator plate 9, using the arc-shaped structure at the bottom of the clamping plate 92, change the direction of the force acting on the clamping plate 92, so that the clamping plate 92 contracts towards the mounting groove 91 and squeezes the mounting spring 93. When the clamping plate 92 and the indicator plate 9 move to the next scale groove 43, due to the existence of the scale groove 43, the clamping plate 92 is separated from the mounting housing 4. At this time, the mounting spring 93 rebounds, driving the clamping plate 92 to extend out of the mounting groove 91 and making it stuck in the scale groove 43 at the corresponding position, thus completing a relatively weak temporary block. Through this temporary block, the staff can more accurately control the contraction distance of the sleeve rod 81. When the contraction distance of the sleeve rod 81 is adjusted, rotate the screw rod 84 in the reverse direction by rotating the knob 86 to make it rotate into the connecting pipe 83 and make the rubber pad 85 abut against the mounting rod 8, thereby completing the limiting work between the mounting rod 8 and the sleeve rod 81, so that when the subsequent mounting rod 8 and sleeve rod 81 squeeze the docking rod 73, there will be no contraction situation. When the sleeve 11 and the insertion tube 12 are docked, then use an additional fixing steel plate to complete the fixing work of the sleeve 11 and the insertion tube 12, and after separating the steel belt 6 from the insertion tube 12, turn the screw rod 84 to separate the rubber pad 85 from the mounting rod 8. At this time, since the limit on the sleeve rod 81 disappears, the limit spring 82 starts to rebound, causing the mounting rod 8 and the sleeve rod 81 to extend. And one end of the sleeve rod 81 is limited by the docking rod 73, so the mounting rod 8 can be better returned to its original position, facilitating the next use.

[0026] Working principle: First, place the load-bearing frame 1 at the designated position. Then, place the sleeve 11 and the insertion tube 12 below the load-bearing frame 1. At this time, it is necessary to ensure that the sleeve 11 is located below the fixing frame 2, and the insertion tube 12 is placed below the sliding frame 21. Then, start the hydraulic cylinders A22 on the fixing frame 2 and the sliding frame 21 through the console 212. Use the hydraulic cylinders A22 to drive the transmission frame 23 to rotate. During the rotation of the transmission frame 23, it can push the connecting frames 24 at both ends to rotate, so that the two clamping arms 25 close together. At this time, the fixing frame 2 and the sliding frame 21 can respectively clamp the sleeve 11 and the insertion tube 12 through the clamping arms 25; Attach the steel belt 6 to the outer wall of the insertion tube 12 near one end of the sleeve 11, and ensure that the scraping plate 62 is aligned with the end of the insertion tube 12. Then rotate the limit frame 64 and put the limit frame 64 on the limit block 66. After that, rotate the screw rod 65 to insert the screw rod 65 into the limit block 66 to limit the steel belt 6; After that, according to the distance that the insertion tube 12 needs to be inserted into the sleeve 11, turn the screw rod 84 by turning the knob 86 to separate the rubber pad 85 from the mounting rod 8. Then, through the cooperation of the screw rod 84 and the connecting pipe 83, manually move the sleeve rod 81 to make it contract towards the mounting rod 8. At this time, the limit spring 82 will contract due to the pressure received, so as to adjust the distance between the sleeve rod 81 and the docking rod 73. At this time, the connecting pipe 83 will drive the indicator plate 9 to move together. During the movement of the indicator plate 9, the clamping plate 92 at the bottom of it will be stuck in the scale groove 43. During the movement of the indicator plate 9, using the arc-shaped structure at the bottom of the clamping plate 92, change the acting direction of the force received by the clamping plate 92, so that the clamping plate 92 contracts towards the installation groove 91 and squeezes the installation spring 93. When the clamping plate 92 and the indicator plate 9 move to the next scale groove 43, due to the existence of the scale groove 43, the clamping plate 92 is separated from the installation housing 4. At this time, the installation spring 93 rebounds, drives the clamping plate 92 to extend out of the installation groove 91, and makes it stuck in the scale groove 43 at the corresponding position, so as to complete a weak temporary block. Through this temporary block, the staff can more accurately control the contraction distance of the sleeve rod 81. After adjusting the contraction distance of the sleeve rod 81, turn the screw rod 84 in the reverse direction by turning the knob 86 to make it rotate into the connecting pipe 83 and make the rubber pad 85 abut against the mounting rod 8, so as to complete the limiting work between the mounting rod 8 and the sleeve rod 81; Then start the hydraulic cylinder B31 to push the sliding frame 21 to move towards the fixed frame 2. During this process, the sliding frame 21 drives the insertion tube 12 to be inserted into the sleeve 11 through the clamping arm 25. During the process of the insertion tube 12 being inserted into the sleeve 11, the outer wall of the sleeve 11 will squeeze the scraping plate 62, so that the scraping plate 62 and the steel belt 6 move along the outer wall of the insertion tube 12. During this process, the scraping plate 62 can clean the sand and gravel attached to the outer wall of the insertion tube 12 and collect it in the steel belt 6. After the sand and gravel are scraped off, they will slide down along the steel belt 6 and finally be discharged through the dust outlet 63. During the movement of the steel belt 6, the mounting rod 8 and the sleeve rod 81 will be driven by the telescopic rod 5 to move towards the docking rod 73. When the sleeve rod 81 abuts against the docking rod 73, it will squeeze the docking rod 73 to make it pass through the mounting hole 71 and dock with the button of the controller 52. At this time, the hydraulic cylinder B31 can be controlled by the controller 52 to close, so that the sliding frame 21 and the insertion tube 12 stop moving and complete the docking work of the sleeve 11 and the insertion tube 12; After the docking rod 73 is squeezed by the sleeve rod 81 and moves in the direction of the controller 52, the docking rod 73 will cooperate with the limit groove 72 to squeeze the fixing spring 74, causing the fixing spring 74 to contract. A steel plate is provided at one end of the docking rod 73 away from the controller 52. When the docking rod 73 touches the button of the controller 52, the steel plate on the docking rod 73 will contact the limit plate 75. At this time, through the cooperation of multiple limit plates 75 and the steel plate, the docking rod 73 is limited to prevent the problem that the controller 52 is damaged due to excessive force of the docking rod 73 squeezing the button of the controller 52. After the connection work of the sleeve 11 and the insertion tube 12 is completed, the steel belt 6 is removed from the insertion tube 12. At this time, the limit of the insertion tube 12 is lost, and the fixing spring 74 starts to rebound, driving the docking rod 73 back to its original position, facilitating repeated operations next time. And after the separation between the steel belt 6 and the insertion tube 12, the screw rod 84 is rotated to separate the rubber pad 85 from the mounting rod 8. At this time, since the limit on the sleeve rod 81 disappears, the limit spring 82 starts to rebound, causing the mounting rod 8 and the sleeve rod 81 to extend. And one end of the sleeve rod 81 is limited by the docking rod 73, so the mounting rod 8 can return to its original position better, facilitating the next use. Then, the hydraulic cylinder A22 is controlled to contract, and by using the transmission functions of the transmission frame 23 and the connection frame 24, the clamping arms 25 on both sides of the sleeve 11 and the insertion tube 12 are driven to open, so that the clamping arms 25 no longer clamp the sleeve 11 and the insertion tube 12. Then, the bearing frame 1 is pushed to move, so that it is removed from the sleeve 11 or the insertion tube 12. Then, the connection work of the next sleeve 11 and insertion tube 12 can be carried out.
