[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0026] Please see Figures 1 to 5 The present invention provides a sleeve joint repair clamping structure, which includes a base plate 1.
[0027] In the embodiments of this utility model, please refer to Figures 1 to 5The base plate 1 is provided with a clamping assembly 3 for clamping and fixing the sleeve joint; the clamping assembly 3 includes a mounting post 31, which is movably disposed above the base plate 1. The mounting post 31 is a polygonal column, and a cylinder 32 is fixedly mounted on each side wall of the mounting post 31. The end of the cylinder 32 is provided with a fixedly connected mounting plate 321, and the end of the mounting plate 321 is provided with a fixedly connected clamping rod a33. A fixedly connected clamping rod b34 is provided on the side wall of the mounting plate 321 near the cylinder 32. A threaded support sleeve 35 is fitted on the outer wall of both the clamping rod a33 and the clamping rod b34, and a fixedly connected anti-slip sleeve 351 is provided on the outer wall of the support sleeve 35; the clamping rod a33 and the clamping rod b34 on the same mounting plate 321 are on the same plane as their corresponding cylinder 32.
[0028] It should be noted that during use, the sleeve joint to be repaired can be taken out and placed inside the multiple clamping rods a33 or outside the multiple clamping rods b34 in the clamping assembly 3 as needed. Then, the multiple cylinders 32 are controlled to retract or extend, thereby allowing the clamping rods a33 and b34, as well as their external support sleeves 35 and anti-slip sleeves 351, to move via the mounting plate 321. This allows the external anti-slip sleeves 351 to clamp the outer wall of the sleeve joint as needed. Thus, when the worker repairs the sleeve joint, the obstruction of the clamping components during the repair process can be reduced, thereby improving the flexibility of the worker's repair operation.
[0029] In the embodiments of this utility model, please refer to Figures 1 to 5 The base plate 1 is provided with an adjustment component 2 for adjusting the angle of the clamping component 3. The adjustment component 2 includes a support column 21, which is rotatably mounted on the base plate 1. The top of the support column 21 is provided with a fixedly connected adapter frame 22, and a rotatably connected rotating shaft 221 is inserted into the adapter frame 22. A fixedly connected adapter rod 23 is sleeved on the outside of the rotating shaft 221. The end of the adapter rod 23 is provided with a rotatably connected rotating rod 231. The end of the rotating rod 231 is fixedly connected to the end of the mounting column 31, and the radial direction of the end of the rotating shaft 221 is perpendicular to the radial direction of the end of the rotating rod 231.
[0030] It should be noted that since the radial direction of the end of the rotating shaft 221 is perpendicular to the radial direction of the end of the rotating rod 231, during use, when the rotating shaft 221 and the rotating rod 231 rotate, the clamping assembly 3 can be driven to rotate in different directions in the vertical plane. In addition, by combining with the horizontal rotation of the rotating column, the angle between the clamping assembly 3 and the externally clamped sleeve joint can be flexibly adjusted, thereby improving the flexibility of the operator in the repair operation of the sleeve joint.
[0031] In the embodiments of this utility model, please refer to Figures 1 to 5The support column 21 has two symmetrically distributed mounting slots 211 inside. Each mounting slot 211 has a through slot 212. A movably connected gripping piece 26 is located within the mounting slot 211. Each gripping piece 26 has a fixedly connected adapter piece 261 on its opposite side. Each adapter piece 261 has a fixedly connected limiting rod 262 on its opposite side. The outer wall of the limiting rod 262 abuts against and slides against the inner wall of the through slot 212, and the end of the limiting rod 262 extends through the through slot 212 to the outside of the support column 21. Each adapter piece 261 has a telescopic rod 27 on its opposite side. The end of the telescopic rod 27 has a fixedly connected mounting piece 271. The outer wall of the mounting piece 271 is fixedly connected to the inner wall of the mounting slot 211. A fixed connection is established, and a fixed connection spring 272 is provided between the holding piece 26 and the mounting piece 271. A fixed connection positioning frame 11 is fitted on the outside of the top support column 21 of the base plate 1. The positioning frame 11 has several annularly distributed limiting holes 111 inside, and the inner wall of the limiting holes 111 abuts against the outer wall of the limiting rod 262. A fixed connection support piece 25 is provided on the outer wall of the adapter frame 22 and the adapter rod 23. A rotatably connected adjusting rod 251 is inserted inside the support piece 25. A fixed connection worm 241 is fitted on the outside of the adjusting rod 251. A meshing worm wheel 24 is provided on the outer wall of the worm 241, and the two worm wheels 24 are respectively fixedly fitted on the outer wall of the corresponding rotating shaft 221 and rotating rod 231.
[0032] It should be noted that: by setting up the worm gear 24 and worm 241, when the operator completes the rotation adjustment of the rotating shaft 221, the self-locking characteristics of the worm gear 24 and worm 241 can prevent the rotating shaft 221 and rotating rod 231 from rotating randomly. Therefore, the stability of the rotating shaft 221 and rotating rod 231 supporting the end clamping assembly 3 after adjustment can be improved.
[0033] By using spring 272, the spring 272 can compress the adapter plate 261 with its own force, thereby causing the adapter plate 261 to move the limiting rod 262 on the outer wall away from the support column 21. Therefore, the limiting rod 262 always has the force to move towards the limiting hole 111, so that the limiting rod 262 can be stably inserted into the limiting hole 111, thereby limiting the horizontal rotation direction of the support column 21 and further improving the stability of the device during maintenance.
[0034] The working principle of the sleeve joint repair clamping structure provided by this utility model is as follows:
[0035] When using this device, the sleeve joint to be repaired can be taken out and placed inside the multiple clamping rods a33 in the clamping assembly 3 as needed. Then, multiple cylinders 32 can be controlled to retract. The retracting cylinders 32 can drive the clamping rods a33 and their external support sleeves 35 and anti-slip sleeves 351 to retract and move towards the mounting column 31 through the mounting plate 321 until the outer wall of the anti-slip sleeve 351 abuts against the outer wall of the sleeve joint, thereby achieving clamping and fixing of the outside of the sleeve joint, which facilitates the repair of the inner wall of the sleeve joint by the staff.
[0036] Similarly, during the repair process, the sleeve joint can be moved to the outside of multiple clamping rods b34, and then multiple cylinders 32 can be extended, so that they can drive the clamping rods b34 and their external support sleeves 35 and anti-slip sleeves 351 to extend and move away from the mounting post 31 through the mounting plate 321, until the outer wall of the anti-slip sleeve 351 abuts against the inner wall of the sleeve joint, thereby achieving clamping and fixing of the inside of the sleeve joint, which facilitates the repair of the outer wall of the sleeve joint by the staff. By clamping the inside and outside of the sleeve joint, the obstruction of the clamping components to the staff's operation during the repair process can be reduced.
[0037] Furthermore, during the repair process, the adjusting rod 251 outside the rotating shaft 221 and rotating rod 231 can be controlled to rotate as needed. The rotating adjusting rod 251 can drive the corresponding rotating shaft 221 and rotating rod 231 to rotate through the meshing of the worm gear 241 and worm wheel 24 on the outer wall, thereby driving the external clamping assembly 3 and the sleeve joint to rotate synchronously, thus realizing the adjustment of the vertical angle of the sleeve joint.
[0038] Simultaneously, the gripping piece 26 can be gripped as needed. During this process, the gripping piece 26 can drive the limiting rods 262 on both sides to move relative to each other through the adapter piece 261, thereby allowing the limiting rods 262 to move out of the limiting hole 111 and release the phenomenon of the support column 21. At this time, the support column 21 can be rotated, thereby driving the sleeve joint clamped above to rotate horizontally. Therefore, it can improve the flexibility of adjusting the angle of the sleeve joint when using this device, and help improve the flexibility of the maintenance operation and the user experience of the staff.
[0039] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0040] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
