Description

Technical Field

[0001] The utility model relates to the technical field of pipeline plugging, and more specifically to an inner expansion ring for pipeline plugging. Background Art

[0002] The inner expansion ring is a technology used for pipeline repair, mainly used to repair the interface misalignment and leakage problems of large-diameter pipelines. It applies pressure to the stainless steel expansion ring through professional hydraulic equipment, and installs the special high-strength sealing waterstop on both sides of the pipeline interface to achieve soft connection and restore the pressure-bearing capacity of the pipeline. The inner expansion ring is composed of two semicircular steel rings, one of which has one joint and the other has two joints. The steps for its use are as follows: connect the end of the steel ring with one joint without a joint to one of the joints of the steel ring with two joints, and then initially fit the two steel rings to the inner wall of the waterstop, and then apply pressure to the two steel rings through professional hydraulic equipment to hold the waterstop, and finally place a steel sheet between the remaining two joints, and release the hydraulic equipment, so that the two steel rings can maintain pressure on the waterstop through the steel sheet.

[0003] At present, when installing the steel sheet, in order to facilitate the installation of the steel sheet, the staff will expand the distance between the two joints and then install the steel sheet. At this time, the steel sheet is not subjected to external force, and the steel sheet is more likely to slide and cause dislocation during the removal of the hydraulic equipment, which requires re-operation. The practicality is insufficient. Therefore, it is urgent to design an inner expansion ring for pipeline plugging to solve the above problem. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides an inner expansion ring for pipe leak plugging to solve the problem that the steel sheet in the above background technology is prone to sliding and causing dislocation during the process of removing the hydraulic equipment.

[0005] The utility model provides the following technical solution: an inner expansion ring for pipeline leak plugging, comprising a first steel ring, a second steel ring, a clamping joint, a first docking assembly, a connecting assembly, and a second docking assembly. The first steel ring and the second steel ring are both semicircular rings. The clamping joint is fixedly installed at one end of the second steel ring, the clamping joint is fixedly connected to one end of the second steel ring, one end of the first steel ring is slidably inserted in the clamping joint, the first docking assembly is fixedly connected to the other end of the first steel ring, the second docking assembly is fixedly connected to the other end of the second steel ring, and the connecting assembly is slidably installed between the first docking assembly and the second docking assembly.

[0006] Furthermore, the first docking assembly includes a first pair of joints, the first pair of joints are groove-shaped, the connection assembly includes a steel sheet, the second docking assembly includes a second pair of joints, the second pair of joints are groove-shaped, and both ends of the steel sheet are slidingly connected to the first pair of joints and the second pair of joints respectively.

[0007] Furthermore, the first docking assembly further includes a slide groove and two first clamping grooves, the slide groove and the two first clamping grooves are both arranged on the top inner wall of the first docking joint, the two first clamping grooves are both perpendicular to the slide groove, the two first clamping grooves are both connected to the slide groove, and the end of the slide groove is located on the end surface of the first docking joint;

[0008] The connection assembly also includes two first clamping blocks, which are both fixedly mounted on the top of the steel sheet, and the slide groove and the two first clamping grooves are both adapted to the first clamping blocks.

[0009] Furthermore, the second docking assembly further comprises two second clamping blocks, and the two second clamping blocks are both fixedly mounted on the top inner wall of the second pair of joints;

[0010] The connecting assembly also includes two second card slots, both of which are opened on the top of the steel sheet, and the second card slots are adapted to the second card blocks.

[0013] Furthermore, two insertion rods are fixedly installed at one end of the first steel ring, and two insertion holes are provided on the inner wall of one end of the clamping joint, and the insertion rods are adapted to the insertion holes.

[0014] Technical effects and advantages of the utility model:

[0015] When the utility model is in use, the waterstop is first fitted to the leaking part of the pipe, and then the first steel ring is inserted into the clamping joint, and the first steel ring and the second steel ring are initially fitted to the inner wall of the waterstop. At this time, hydraulic equipment is used to apply pressure to the first steel ring and the second steel ring, so that the first pair of joints and the second pair of joints move away from each other to a certain position. At this time, the steel sheet is inserted into the first pair of joints, and the two first clamping blocks are made to slide inward along the slide groove. When one of the first clamping blocks slides to the end of the slide groove, the two first clamping blocks will slide to the positions corresponding to the two first clamping grooves. At this time, the steel sheet is slid to the left, so that the two first clamping blocks slide into the two first clamping grooves respectively, so as to limit the forward and backward sliding of the steel sheet. At this time, the hydraulic equipment is released, and the second pair of joints will be close to the steel sheet. When the second pair of joints are meshed with the steel sheet and slide to a certain position, the two second clamping blocks will mesh into the two second clamping grooves, further limiting the sliding of the steel sheet.

[0016] By setting up the first docking assembly and the connecting assembly, after the staff installs the steel sheet into the first pair of joints, they can slide the steel sheet to the left to impose a forward and backward sliding limit on the steel sheet, preventing it from sliding forward and backward and causing dislocation when the hydraulic equipment is removed, thereby improving its practicality.
