Description

Technical Field

[0001] This utility model relates to the field of industrial production technology, and more specifically, it relates to a clamp-type pipe repair device. Background Technology

[0002] During industrial production operations, pipeline systems often experience emergency failures such as leaks and ruptures, requiring timely repairs to prevent greater losses. Currently, most common pipeline repair devices on the market use traditional bolt fastening methods, which require the use of specialized tools to tighten multiple bolts during installation. This not only makes the installation process cumbersome and time-consuming, but also makes it difficult to achieve rapid repairs in emergency situations, potentially leading to wider leaks and losses.

[0003] With the increasing demand for maintenance of various pipeline systems, maintenance personnel often need to carry out pipeline repair work in various complex environments. The disassembly process of traditional repair devices after use also requires a lot of time and manpower, especially in confined spaces or special environments, where disassembly is more difficult. At the same time, due to the lack of effective sealing structure design, many repair devices are prone to problems such as poor sealing and insecure fixing during use, which affects the repair effect and may even require repeated installation and adjustment. This not only reduces maintenance efficiency but also increases maintenance costs. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a clamp-type pipe repair tool to solve the technical problem mentioned in the background art that requires the use of professional tools to tighten multiple bolts during the installation process.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a clamp-type pipe repair device, comprising an installation sleeve, on which a repair mechanism is provided. The repair mechanism includes a tension spring, a repair plate, a sealing gasket, and a push-lock mechanism. Multiple sets of tension springs are installed on the inner wall of the installation sleeve. Two sets of repair plates are installed at the bottom ends of the multiple sets of tension springs. The sealing gasket is installed on the inner side of the two sets of repair plates. The push-lock mechanism includes a push rod, a connecting rod, a connecting block, and a rotating sleeve. Multiple sets of push rods are slidably installed on the outer wall of the installation sleeve. The connecting rod is installed at the top of the multiple sets of push rods. The connecting block is installed at both ends of the multiple sets of connecting rods. The rotating sleeve is rotatably installed on the outer side of the multiple sets of connecting rods.

[0008] The present invention is further configured such that guide rods are installed on the outer sides of both sets of repair plates. Multiple sets of guide rods are provided and slidably connected to the mounting sleeve. By providing multiple sets of guide rods on the outer side of the repair plate and slidably connecting them to the mounting sleeve, the stability and accuracy of the repair plate during movement are ensured, effectively preventing the repair plate from shifting or shaking, and improving the repair effect.

[0009] The present invention is further provided that each of the multiple sets of connecting rods and the mounting sleeve is connected with a connecting spring. The connecting spring provides a suitable elastic force between the connecting rod and the mounting sleeve, which can ensure stability when locking and provide return force when unlocking, making the entire locking and unlocking process smoother and more reliable.

[0010] The present invention is further provided that the inner side of the rotating sleeve is provided with an unlocking groove, and there are multiple sets of unlocking grooves. The design of multiple sets of unlocking grooves enables the rotating sleeve to accurately release the contact with the connecting rod when it rotates to a specific position, thereby realizing the quick unlocking function and improving the ease of operation of the device.

[0011] The present invention is further configured such that a push spring is connected between each of the multiple sets of connecting blocks and the outer wall of the mounting sleeve. The push spring provides a continuous thrust between the connecting block and the outer wall of the mounting sleeve, which not only ensures the stability of the locked state, but also helps the connecting block to quickly reset when unlocking, thereby improving the reliability of the device.

[0012] The present invention is further provided that the outer wall of the rotating sleeve is provided with anti-slip ridges, and multiple sets of anti-slip ridges are distributed on the outer wall of the rotating sleeve. The uniform distribution of multiple sets of anti-slip ridges increases the friction of the rotating sleeve surface, enabling the operator to better control the rotation of the rotating sleeve and improve the operating performance of the device.

[0013] The present invention is further configured such that a limiting mechanism is provided between the rotating sleeve and the mounting sleeve. The limiting mechanism includes a mounting plate, a slide bar, an arc bar, a slide seat, and a slide groove. Multiple sets of mounting plates are mounted on the outer wall of the mounting sleeve. Multiple sets of slide bars are mounted on the outer wall of the mounting sleeve. Multiple sets of arc bars are mounted on multiple sets of mounting plates. Multiple sets of slide seats are mounted on the inner side of the rotating sleeve and are slidably connected to multiple sets of arc bars. The slide groove is located on the bottom surface of multiple sets of slide seats and is slidably connected to multiple sets of slide bars, providing precise guidance and limiting for the movement of the rotating sleeve.

[0014] The present invention is further configured such that baffles are installed at the top of each of the multiple sets of slide bars. The baffles provide an effective limiting function for the slide block, preventing the slide block from detaching from the slide bar during movement, ensuring the reliable operation of the limiting mechanism, and improving the safety of the entire device.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a clamp-type pipe repair tool, which has the following features:

[0017] Beneficial effects:

[0018] 1. By setting a repair mechanism on the mounting sleeve, using a tension spring to provide elastic support for the repair plate, and installing a sealing gasket on the inside of the repair plate, combined with the sliding connection between the guide rod and the mounting sleeve, the repair plate can move smoothly, and the sealing gasket can quickly and accurately fit against the pipeline leak, effectively solving the problem of cumbersome installation of traditional repair devices.

[0019] 2. Through the ingenious cooperation of the push rod, connecting rod, connecting block and rotating sleeve in the push-lock mechanism, combined with the elastic effect of the connecting spring and push spring, as well as the design of the unlocking groove and anti-slip convex strip, the repair device can be quickly locked and easily unlocked, overcoming the time-consuming disassembly and assembly defects in the existing technology.

[0020] 3. The limiting mechanism, through the coordinated action of the mounting plate, slide bar, arc bar, slide seat and slide groove, provides precise guidance and limiting for the movement of the rotating sleeve. Combined with the blocking effect of the baffle, it not only ensures the accuracy and stability of the locking process, but also effectively prevents the slide seat from disengaging, thereby improving the reliability and service life of the entire repair device.

[0030] Please see Figures 1-5 A clamp-type pipe repair device includes an installation sleeve 1, on which a repair mechanism is provided. The repair mechanism includes a tension spring 2, a repair plate 3, a sealing gasket 4, and a push-lock mechanism. Multiple sets of tension springs 2 are installed on the inner wall of the installation sleeve 1. Two sets of repair plates 3 are installed at the bottom of the multiple sets of tension springs 2. The sealing gasket 4 is installed on the inner side of the two sets of repair plates 3. The push-lock mechanism includes a push rod 5, a connecting rod 6, a connecting block 7, and a rotating sleeve 8. Multiple sets of push rods 5 are slidably installed on the outer wall of the installation sleeve 1. The connecting rod 6 is installed at the top of the multiple sets of push rods 5. The connecting block 7 is installed at both ends of the multiple sets of connecting rods 6. The rotating sleeve 8 is rotatably installed on the outer side of the multiple sets of connecting rods 6.

[0031] Guide rods 9 are installed on the outer side of both sets of repair plates 3. Multiple sets of guide rods 9 are provided and are slidably connected to the mounting sleeve 1.

[0032] Each of the multiple sets of connecting rods 6 is connected to the mounting sleeve 1 by a connecting spring 10.

[0033] The inner side of the rotating sleeve 8 is provided with an unlocking slot 11, and there are multiple sets of unlocking slots 11.

[0034] Push springs 12 are provided between the multiple sets of connecting blocks 7 and the outer wall of the mounting sleeve 1.

[0035] The outer wall of the rotating sleeve 8 is provided with anti-slip ridges 13, and multiple sets of anti-slip ridges 13 are distributed on the outer wall of the rotating sleeve 8.

[0036] In this embodiment, when pipe repair is required, the mounting sleeve 1 is fitted onto the outer wall of the pipe and moved to the repair location. The rotating sleeve 8 is rotated so that its inner wall abuts against multiple sets of connecting rods 6, applying downward pressure. The connecting rods 6 drive the connecting block 7 and push rod 5 to slide along the mounting sleeve 1. The connecting block 7 compresses the push spring 12, and the bottom end of the push rod 5 pushes the repair plate 3. The repair plate 3 slides along the mounting sleeve 1 via the guide rod 9 and simultaneously stretches the tension spring 2. Both sets of repair plates 3 move inward simultaneously, causing the sealing gasket 4 to contact and adhere tightly to the pipe repair location. The push spring 12 pushes the connecting block 7... When the connecting rod 6 is pushed, it applies a reverse force to the inner wall of the rotating sleeve 8, thereby causing the sealing gasket 4 to seal the damaged part of the pipe. When it needs to be disassembled, the rotating sleeve 8 is rotated to drive the unlocking groove 11 to rotate. When the multiple unlocking grooves 11 move to the top of the multiple connecting rods 6, the inner wall of the rotating sleeve 8 releases its contact with the connecting rod 6. The push spring 12 pushes the connecting block 7 to move outward, and at the same time, the connecting rod 6 drives the push rod 5 to slide outward, so that the push rod 5 releases its contact with the repair plate 3. The two repair plates 3 are pulled outward by the elastic reset of the multiple tension springs 2, so that the sealing gasket 4 releases its seal on the pipe.

[0037] Please see Figure 5 As one implementation of the limiting mechanism: a limiting mechanism is provided between the rotating sleeve 8 and the mounting sleeve 1. The limiting mechanism includes a mounting plate 14, a slide bar 15, an arc bar 16, a slide seat 17, and a slide groove 18. Multiple sets of mounting plates 14 are installed on the outer wall of the mounting sleeve 1. Multiple sets of slide bars 15 are installed on the outer wall of the mounting sleeve 1. Multiple sets of arc bars 16 are installed on multiple sets of mounting plates 14 respectively. Multiple sets of slide seats 17 are installed on the inner side of the rotating sleeve 8 and are slidably connected to multiple sets of arc bars 16 respectively. The slide groove 18 is provided on the bottom surface of multiple sets of slide seats 17 and is slidably connected to multiple sets of slide bars 15 respectively.

[0038] Each of the multiple sets of sliders 15 has a baffle 19 installed at its top.

[0039] More specifically, when the rotating sleeve 8 rotates, the slide block 17 slides along the arc-shaped strip 16 and slides along the slide bar 15 through the slide groove 18 provided on the bottom surface. When the inner wall of the rotating sleeve 8 abuts against the connecting rod 6, the slide block 17 simultaneously abuts against the baffle 19. The baffle 19 blocks the slide block 17. The arc-shaped strip 16 is installed on the mounting plate 14 to provide guidance for the slide block 17. The slide block 17 is installed on the inner side of the rotating sleeve 8 and slides in cooperation with the arc-shaped strip 16. The sliding connection between the slide groove 18 and the slide bar 15 ensures the accuracy of the movement of the rotating sleeve 8. The baffle 19 is installed on the top of the slide bar 15 to prevent the slide block 17 from disengaging. The limiting mechanism ensures the accuracy and stability of the entire locking process.

[0040] In summary, when the entire equipment is in use or operation: When pipe repair is required, the mounting sleeve 1 is fitted onto the outer wall of the pipe and moved to the area requiring repair. The rotating sleeve 8 is rotated so that its inner wall abuts against multiple sets of connecting rods 6, applying downward pressure. The connecting rods 6 drive the connecting block 7 and push rod 5 to slide along the mounting sleeve 1. The connecting block 7 compresses the push spring 12, and the bottom end of the push rod 5 pushes the repair plate 3. The repair plate 3 slides along the mounting sleeve 1 via the guide rod 9, simultaneously stretching the tension spring 2. Both sets of repair plates 3 move inward simultaneously, causing the sealing gasket 4 to contact and adhere tightly to the pipe repair area. The push spring 12 then pushes... The connecting block 7 simultaneously pushes the connecting rod 6 to apply a reverse force to the inner wall of the rotating sleeve 8, thereby causing the sealing gasket 4 to seal the damaged part of the pipe. When it needs to be disassembled, rotating the rotating sleeve 8 drives the unlocking groove 11 to rotate. When multiple sets of unlocking grooves 11 move to the top of multiple sets of connecting rods 6, the inner wall of the rotating sleeve 8 releases its contact with the connecting rod 6. The push spring 12 pushes the connecting block 7 to move outward, and at the same time, the connecting rod 6 drives the push rod 5 to slide outward, so that the push rod 5 releases its contact with the repair plate 3. The two sets of repair plates 3 are pulled outward by the elastic reset of multiple sets of tension springs 2, so that the sealing gasket 4 releases its seal on the pipe.

[0041] When the rotating sleeve 8 rotates, the slide block 17 slides along the arc strip 16 and slides along the slide bar 15 through the slide groove 18 provided on the bottom surface. When the inner wall of the rotating sleeve 8 abuts against the connecting rod 6, the slide block 17 abuts against the baffle 19 at the same time. The baffle 19 blocks the slide block 17. The arc strip 16 is installed on the mounting plate 14 to provide guidance for the slide block 17. The slide block 17 is installed on the inner side of the rotating sleeve 8 and slides in cooperation with the arc strip 16. The sliding connection between the slide groove 18 and the slide bar 15 ensures the accuracy of the movement of the rotating sleeve 8. The baffle 19 is installed on the top of the slide bar 15 to prevent the slide block 17 from disengaging. The limiting mechanism ensures the accuracy and stability of the entire locking process.
