Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a lining reinforcer. Background Art

[0002] In the existing pipeline repair technology, when the pipeline is damaged due to aging, corrosion or external force, various methods are usually used to repair it in order to restore the normal use of the pipeline. Lining reinforcement technology is widely used due to its advantages such as convenient construction and little impact on the internal environment of the pipeline.

[0003] Lining reinforcement technology usually requires that the lining material be sent into the interior of the pipeline through specific equipment or methods, and that it be tightly fitted to the inner wall of the pipeline by heating, pressurizing, and other means to achieve the reinforcement effect, and the part extending out of the pipeline needs to be fixed to the outer wall of the pipeline by a reinforcer. Currently, many lining reinforcers are used to fix the pressure cap by bolting the pressure cap to the components on the outer wall of the pipeline, thereby reinforcing the lining. However, the operation is relatively cumbersome. For this reason, we propose a lining reinforcer. Utility Model Content

[0004] The purpose of the utility model is to provide a lining reinforcer to solve the problems raised by the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a liner reinforcer, comprising a pipe body, a liner is arranged inside the pipe body, a clamping assembly for pressing the liner is arranged on one side of the pipe body, an annular fixing plate is fixedly installed on the outside of the pipe body, and a plurality of slots are opened on the surface of the annular fixing plate;

[0006] The clamping assembly includes a pressing cap, a plurality of limiting rods and a baffle, the pressing cap is located on the side of the pipe body, the limiting rod is hinged on one side of the pressing cap, the baffle is welded to one end of the limiting rod, the limiting rod passes through the slot, and a plurality of groups of limiting parts for limiting the baffle are installed on the side of the pipe body, and an adjustment assembly for driving the movement of the annular fixing plate is provided on one side of the pipe body.

[0007] Preferably, the portion of the liner extending out of the pipe body is turned outward and sleeved on the outside of the pipe body.

[0008] Preferably, the limiting rods are distributed in a circular shape with equal spacing on one side of the pressure cap, the number of the slots is consistent with that of the limiting rods, and the limiting rods are distributed in a circular shape with equal spacing on the outer side of the annular fixing plate.

[0009] Preferably, the axial cross-section of the baffle is rectangular.

[0010] Preferably, a set of the limiting members includes two limiting frames which are in a U shape and welded to the side surface of the annular fixing plate, and the inner dimensions of adjacent two limiting frames are properly matched with the size of the baffle plate.

[0011] Preferably, the adjusting assembly includes a fixing plate and a threaded rod. The fixing plate is fixedly installed on the outer side of the pipeline body, the threaded rod is threadedly connected in the fixing plate, and one end of the threaded rod is rotatably installed on one side of the annular fixing plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. For this lining reinforcement device, after the lining passes through the pipeline body, the part longer than the pipeline body is turned outwards and attached to the outer wall of the pipeline body. Then, the end face of the pipeline body is pressed by the compression cap. By rotating the limiting rod, the limiting rod passes through the inner side of the clamping groove, and the baffle plate moves to the side of the annular fixing plate away from the compression cap. Then, by rotating the threaded rod, the annular fixing plate is driven to slide in the direction away from the compression cap. The annular fixing plate abuts against the baffle plate, pulling the limiting rod and the compression cap to one side, thereby pressing the turned-out part of the lining tightly, completing the reinforcement work of the lining. Compared with the fixing method of multiple bolts, the operation is simpler and the reinforcement efficiency is improved.

[0014] 2. For this lining reinforcement device, through the arranged limiting frames, when the annular fixing plate moves, it can be stuck on the outer side of the baffle plate to limit the baffle plate, making the baffle plate more firm after fixation, and further ensuring the stability of the positions of the limiting rod and the compression cap.

A pressing component for pressing the lining 2 is arranged on one side of the pipeline body 1. An annular fixing plate 4 is fixedly installed on the outer side of the pipeline body 1, and a plurality of clamping grooves 5 are formed on the surface of the annular fixing plate 4;

[0022] The pressing component includes a pressing cap 3, a plurality of limiting rods 6 and a baffle 7. The pressing cap 3 is located on the side of the pipeline body 1. The limiting rods 6 are hinged on one side of the pressing cap 3. The baffle 7 is welded to one end of the limiting rods 6. The limiting rods 6 pass through the clamping grooves 5. A plurality of limiting parts for limiting the baffle 7 are installed on the side of the pipeline body 1. An adjusting component for driving the annular fixing plate 4 to move is arranged on one side of the pipeline body 1.

[0023] Specifically, by blocking the pressing cap 3 at one end of the pipeline body 1, the lining 2 is pressed. The limiting rods 6 are passed through the clamping grooves 5, and the annular fixing plate 4 is driven to move through the adjusting component, so as to tighten the baffle 7, the limiting rods 6 and the pressing cap 3. The pressing cap 3 is fixed, thus completing the reinforcement work of the lining 2.

[0024] Wherein: The part of the lining 2 extending out of the pipeline body 1 turns outwards and is sleeved on the outer side of the pipeline body 1, which is convenient for pressing the lining 2 on one side of the pipeline body 1 through the pressing cap 3.

[0025] Wherein: The limiting rods 6 are annularly and equidistantly distributed on one side of the pressing cap 3. The number of the clamping grooves 5 is the same as that of the limiting rods 6, and the limiting rods 6 are annularly and equidistantly distributed on the outer side of the annular fixing plate 4.

[0026] Wherein: The axial section of the baffle 7 is rectangular. A set of limiting parts includes two limiting frames 8. The limiting frames 8 are in a C shape. The limiting frames 8 are welded to the side of the annular fixing plate 4. The inner dimensions of two adjacent limiting frames 8 are appropriately matched with the size of the baffle 7. By arranging the limiting frames 8, when the annular fixing plate 4 moves, the limiting frames 8 can be stuck on the outer side of the baffle 7 to limit the baffle 7, making the baffle 7 more firm after being fixed.

[0027] Wherein: The adjusting component includes a fixing plate 9 and a threaded rod 10. The fixing plate 9 is fixedly installed on the outer side of the pipeline body 1. The threaded rod 10 is threadedly connected in the fixing plate 9. One end of the threaded rod 10 is rotatably installed on one side of the annular fixing plate 4. Rotating the threaded rod 10 drives the annular fixing plate 4 to move, and the annular fixing plate 4 pulls the baffle 7 to move.

[0028] Working principle: The utility model is a lining reinforcer. After the lining 2 passes through the pipe body 1, the part longer than the pipe body 1 is turned outward and attached to the outer wall of the pipe body 1. Then, the end face of the pipe body 1 is pressed by the pressing cap 3. By rotating the limit rod 6, the limit rod 6 passes through the inner side of the slot 5, and the baffle 7 moves to the side of the annular fixing plate 4 away from the pressing cap 3. Then, by rotating the threaded rod 10, the annular fixing plate 4 is driven to slide in the direction away from the pressing cap 3, and then the baffle 7 enters the inner side of the limit frame 8. With the movement of the annular fixing plate 4, the annular fixing plate 4 contacts the baffle 7, pulling the limit rod 6 and the pressing cap 3 to one side, thereby pressing the turned-out part of the lining 2, thereby completing the reinforcement of the lining 2.
