Description

A locking mechanism for traction pipe installation Technical Field

[0001] This utility model relates to the field of traction pipe processing technology, and specifically to a locking mechanism for traction pipe installation. Background Technology

[0002] PE traction pipe is a flexible pipe made of high-density polyethylene through extrusion vacuum forming, with smooth inner and outer walls. It is mainly used in areas where excavation is not feasible.

[0003] The patent, CN201210244471.8, entitled "Pipe Pre-traction Connection Device," includes: a lifting ring, a connecting plate, a first connecting rod, a second connecting rod, a first connecting plate, and a second connecting plate. The lifting ring is located on the outer side of the connecting plate. One end of the first connecting rod is connected to the inner side of the connecting plate, and the other end is connected to the inner side of the first connecting plate. One end of the second connecting rod is connected to the inner side of the connecting plate, and the other end is connected to the inner side of the second connecting plate. The connection device further includes a support rod, one end of which is mounted on the first connecting plate, and the other end of which is mounted on the second connecting plate. A support rod length adjustment device is provided on the support rod. The pipe pre-traction connection device of this invention allows the length of the support rod to be adjusted according to the inner diameter of the pipe, thus making it applicable to various specifications of pipes and possessing versatility. Furthermore, it has a large adjustment range and can be used with various pipes of different diameters.

[0004] During the production of traction pipes, the pipes need to be vacuum dried and cooled inside the equipment. Since each traction pipe is approximately 36-42 meters long, it weighs several hundred kilograms or even several tons. When placing it into the equipment for drying and cooling, two forks are needed to work simultaneously at both ends of the traction pipe. In the prior art, including the aforementioned patent, in order to facilitate the insertion of the traction pipe into the equipment, the traction pipe needs to be cut in the middle, and then the two traction pipes are connected by splicing. Then, a large groove of about one-third of the circumference is opened on the end of one of the traction pipes, and a hand is inserted into the traction pipe to operate, thereby splicing the two traction pipes together, and then pulling them by a traction machine. Therefore, the splicing process of the pipe makes the installation mechanism suitable for a specific type of traction pipe, which is inconvenient for users to adjust according to the inner diameter of the pipe.

[0007] Furthermore, the abutment component includes a slide rail seat, which is fixedly connected to the inner wall of the bottom cover. A slide rod is slidably disposed inside the slide rail seat, and an arc-shaped abutment block is fixedly connected to the other end of the slide rod.

[0008] Furthermore, the transmission assembly includes a rotating rod, which is rotatably mounted inside the bottom cover and the top cover via bearings. A second gear is fixedly sleeved on the outside of the rotating rod. A first gear is rotatably mounted on the top of the slide rail seat. The first gear meshes with the second gear. A guide post extending out of the slide rail seat is fixedly connected to the slide rod. An arc-shaped groove that mates with the guide post is provided on the first gear.

[0009] Furthermore, the locking assembly includes a sliding sleeve, one end of the rotating rod is rotatably mounted on the bottom cover, the other end of the rotating rod extends through the top cover and is fixedly connected to a top block, the outer side of the rotating rod extending through the top cover is slidably mounted with a sliding sleeve, the sliding sleeve and the top block are connected by a spring, a plug strip is fixedly connected to the side of the sliding sleeve near the top cover, and the top cover has several plug holes for use with the plug strip.

[0010] Furthermore, a plug-in post is fixedly connected to the outer side of the arc-shaped abutment block.

[0011] Furthermore, a silicone pad is fixedly connected to one side of the arc-shaped abutment block against the traction tube.

[0012] Furthermore, the bottom cover is provided with a sliding groove for the sliding rod to slide.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0025] Please refer to Figures 1-3. A locking mechanism for installing a traction tube includes a bottom cover 1. The bottom cover 1 is detachably connected to a top cover 4. Multiple abutment components are radially slidably arranged inside the bottom cover 1 and the top cover 4. Each abutment component is driven by a transmission component. An adjustment component for locking the transmission component is provided on the top cover 4.

[0026] The abutment assembly includes a slide rail seat 2, which is fixedly connected to the inner wall of the bottom cover 1. A slide rod 21 is slidably arranged inside the slide rail seat 2, and an arc-shaped abutment block 22 is fixedly connected to the other end of the slide rod 21. A groove 11 for the slide rod 21 to slide is provided on the bottom cover 1. Both the bottom cover 1 and the top cover 4 are disc-shaped structures. The slide rail seat 2 has four guide rail structures evenly distributed on the outer side of the circular plate. The slide rod 21 is slidably arranged in the guide rail. After the slide rod 21 passes through the groove 11 and exits the bottom cover 1, it is fixedly connected to the arc-shaped abutment block 22.

[0027] The transmission assembly includes a rotating rod 5, which is rotatably mounted inside the bottom cover 1 and the top cover 4 via bearings. A second gear 51 is fixedly sleeved on the outside of the rotating rod 5. A first gear 3 is rotatably mounted on the top of the slide rail seat 2, and the first gear 3 meshes with the second gear 51. A guide post 211 that extends out of the slide rail seat 2 is fixedly connected to the slide rod 21. An arc-shaped groove 31 that mates with the guide post 211 is opened on the first gear 3. The guide post 211 is inserted into the arc-shaped groove 31. As the first gear 3 rotates, the guide post 211 will move along the arc-shaped groove 31, thereby driving the slide rod 21 to slide within the slide rail seat 2.

[0028] The locking assembly includes a sliding sleeve 6. One end of a rotating rod 5 is rotatably mounted on the bottom cover 1, and the other end of the rotating rod 5 passes through the top cover 4 and is fixedly connected to a top block 53. A through hole 41 is provided on the top cover 4. The rotating rod 5 passes through the through hole 41 and passes through the top cover 4 to connect to the top block 53. The sliding sleeve 6 is slidably mounted on the outer side of the end of the rotating rod 5 that passes through the top cover 4. The sliding sleeve 6 and the top block 53 are connected by a spring 7. One end of the spring 7 is fixedly connected to the top block 53, and the other end is fixedly connected to the sliding sleeve 6. A plug strip 61 is fixedly connected to the side of the sliding sleeve 6 near the top cover 4. Several plug holes 42 that cooperate with the plug strip 61 are provided on the top cover 4. The plug holes 42 are equidistantly arranged on the outer side of the through hole 41. A limit groove 62 is provided inside the sliding sleeve 6. A limit ridge 52 is fixedly connected to the outer side of the rotating rod 5. The sliding sleeve 6 is slidably mounted on the outer side of the rotating rod 5 through the cooperation of the limit ridge 52 and the limit groove 62, and the sliding sleeve 6 cannot rotate relative to the rotating rod 5.

[0029] Furthermore, a plug-in post 221 is fixedly connected to the outer side of the arc-shaped abutment block 22. The plug-in post 221 is fixedly connected to the periphery of the arc-shaped abutment block 22. Four mounting holes adapted to the plug-in post 221 are opened at the port of the traction tube. The position of each mounting hole corresponds to the position of the plug-in post 221.

[0030] Specifically, after aligning the positions of the plug pins 221 with the mounting holes around the traction tube port, the user holds the sliding sleeve 6 and slides it upward against the elastic force of the spring 7, causing the plug strip 61 to be pulled out of the plug hole 42. Then, the user starts to rotate the sliding sleeve 6, causing the sliding sleeve 6 to drive the rotating rod 5 to rotate, thereby enabling the drive component to drive the abutment component to move radially, so that the abutment component abuts against the traction tube. By holding the top block 53 and sliding the sliding sleeve 6 along the rotating rod 5, the plug strip 61 is inserted back into the corresponding plug hole 42, thereby locking the transmission component.

[0031] Furthermore, the arc-shaped abutment 22 is fixedly connected to a silicone pad on one side of the traction tube.

[0032] Furthermore, by fixing silicone pads to the two sides of the slide rail seat, the deformation capability of the silicone pads eliminates the possible errors when the plug strip 61 is accurately inserted into the through hole 41, ensuring the stability of the installation mechanism installed on the traction tube.

[0033] Furthermore, a ring 43 is fixedly connected to the top center of the top cover 4.

[0034] In this utility model, referring to Figures 1 to 3, firstly, after aligning the insertion pin 221 with the mounting holes on the periphery of the traction tube port, the user holds the sliding sleeve 6 and slides it upward against the elastic force of the spring 7, causing the insertion strip 61 to be pulled out of the insertion hole 42. Then, the user starts to rotate the sliding sleeve 6, causing the sliding sleeve 6 to drive the rotating rod 5 to rotate. During this process, the second gear 51 drives the first gear 3 to rotate, causing the guide pin 211 to move along the arc groove 31. This allows the guide pin 211 to drive the sliding rod 21 to slide radially within the slide rail seat 2, so that the insertion pin 221 is inserted into the mounting hole, and the arc-shaped abutment 22 abuts against the traction tube. Then, the user holds the top block 53 and slides the sliding sleeve 6 along the rotating rod 5, causing the insertion strip 61 to be inserted into the corresponding insertion hole 42 again, thus locking the transmission component.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
