Description
Technical Field
[0001] The utility model relates to the technical field of installation devices, and in particular to an installation device for repairing and constructing an inner liner pipe. Background Art
[0002] Liner pipe is a pipe fitting used to enhance the performance of pipelines. It is usually installed inside pipelines to improve the performance of pipelines or solve specific problems. It is widely used to solve the corrosion and scaling problems of oil pipelines, the repair of metal pipelines for civil water and gas transportation, and industrial fluid transportation. When using UV-curing trenchless repair technology, it is necessary to use mechanical traction to drag the felt hose soaked in photosensitive resin into the repaired pipeline, fix one end of the fiberglass hose to the end of the old pipeline, use compressed air to open the pipe so that it is close to the inner wall of the pipeline, and use UV light racks to cure the resin inside the pipeline to form a new high-strength resin-lined pipe to complete the repair.
[0003] During the repair construction of the liner pipe, when fixing one end on the old pipe, since the uncured liner is relatively soft, most of the installation devices currently used are fixed by clamping, but the outer surface of the liner pipe cannot be completely fitted with the old pipe when clamping. When compressed air enters the liner pipe, if it is directly extended into the inner liner pipe from the fixed end to blow it open, the fixed end of the liner pipe cannot be blown to fit with the old pipe. If it is blown directly from the outside of the fixed end, the unclamped part of the fixed end of the liner pipe is easily separated from the old pipe, affecting the flatness after subsequent curing. In addition, its diameter is smaller than the old pipe and cannot be fixed by the reverse sleeve method. In view of the above defects, the present utility model is proposed. Utility Model Content

[0024] The above and other technical features and advantages of the utility model are further described below in conjunction with the accompanying drawings and embodiments. However, the following embodiments are only preferred embodiments of the utility model, not all of them. Example
[0025] like Figure 1-5As shown, the utility model provides a liner pipe repair construction and installation device, including an end support pipe 1, a windshield fixed outer cover 2 for windshield is sleeved on the outer side of one end of the end support pipe 1, a fixing component 3 for fixing on the old pipe is sleeved between the outer side of the end support pipe 1 and the inner side of the windshield fixed outer cover 2, a limiting clamping plate 5 for limiting the end support pipe 1 is fixed on one end of the end support pipe 1 close to the windshield fixed outer cover 2, a limiting clamping groove 6 matched with the limiting clamping plate 5 is opened inside the windshield fixed outer cover 2, the limiting clamping plate 5 and the limiting clamping groove 6 are both set to be annular in shape matched with the end support pipe 1, the thickness of the limiting clamping plate 5 is equal to the thickness of the limiting clamping groove 6, and the innermost circle diameter of the windshield fixed outer cover 2 is equal to the inner circle diameter of the end support pipe 1;
[0026] The fixing assembly 3 includes an inner fixing cover 31, an old pipe clamping plate 32, an adjusting screw barrel 33 and an adjusting screw rod 34. The outer surface of the inner fixing cover 31 is threadedly fixedly connected to the inner wall of the windshield fixing outer cover 2. A plurality of old pipe clamping plates 32 for clamping and fixing the old pipe are equidistantly arranged inside the inner fixing cover 31. The outer side of each old pipe clamping plate 32 is rotatably connected to an adjusting screw barrel 33 through a bearing, and the inner side of the adjusting screw barrel 33 is threadedly sleeved with an adjusting screw rod 34. The end of the adjusting screw rod 34 extending to the outer side of the adjusting screw barrel 33 is fixed to the inner wall of the inner fixing cover 31, and is used to drive the old pipe clamping plate 32 to fit the outer surface of the old pipe and clamp and fix it;
[0027] When fixing, first put the inner fixing cover 31 on the inner lining tube, then insert the end support tube 1 into the end of the inner lining tube that needs to be fixed, prop up the inner lining tube through the end support tube 1, cut the excess part of the inner lining tube and lay it on the limiting clamping plate 5, push the inner fixing cover 31 so that the inner fixing cover 31 abuts against the cut section of the inner lining tube, and cooperates with the limiting clamping plate 5 to clamp the inner lining tube, and then screw the windshield fixing outer cover 2 to the outside of the inner fixing cover 31 so that the limiting clamping plate 5 is engaged with the inside of the limiting clamping groove 6, the windshield fixing outer cover 2 and the inner fixing cover 31 cooperate to clamp the end support tube 1 and the cut part of the inner lining tube, so that the inner lining tube and the end support tube 1 can be fixed, and the ultraviolet lamp holder will be opened after it is aligned with the inside of the inner fixing cover 31, so that the inner lining tube on the outer surface of the end support tube 1 can be cured. The fixed cover 31 covers the cut part of the liner pipe to prevent the cut part from being solidified. Then the inner fixed cover 31 is put on the old pipe, and the adjusting screw 33 is turned one by one. Under the action of the thread, the old pipe clamp 32 is driven to move and clamp the old pipe, so that the end of the inner liner pipe can be fixed to the old pipe, and then the other end of the inner liner pipe can be passed through the old pipe. When the inner liner pipe is blown open and solidified inside the old pipe, the windproof fixed outer cover 2 is twisted to separate the windproof fixed outer cover 2 from the inner fixed cover 31, so that the clamping of the windproof fixed outer cover 2 and the inner fixed cover 31 on the limit clamp 5 is released, and the end support pipe 1 can be pulled out from the inner liner pipe, and then the adjusting screw 33 is twisted one by one to release the fixation of the old pipe clamp 32 and the old pipe, the fixing assembly 3 can be separated from the old pipe, and then the excess inner liner pipe can be cut off.
[0028] A guide support tube 7 is fixed to the end of the end support tube 1 away from the windshield fixed outer cover 2, and the outer surface of the guide support tube 7 away from the end of the end support tube 1 is set to be inclined inward, and the guide support tube 7 is used for guidance, so that the end support tube 1 is convenient to insert into the inner lining tube, and the outer ring diameter of the end support tube 1 is equal to the inner ring diameter of the inner lining tube, so as to ensure that the end support tube 1 can fully open the inner lining tube, and the side outer surface of the windshield fixed outer cover 2 away from the end support tube 1 is equidistantly fixed with a plurality of auxiliary grips 4, which are used to fix and control the windshield fixed outer cover 2, so as to facilitate the fixation of the windshield fixed outer cover 2 and the inner fixed cover 31, and also to facilitate the rotation of the windshield fixed outer cover 2 for disassembly after the inner lining tube is cured. The outer surface of the inner fixed cover 31 and the inner wall of the windshield fixed outer cover 2 are set to be threads that cooperate with each other, and the windshield fixed outer cover 2 and the inner fixed cover 31 are both made of light-shielding materials, so as to shield the cut part of the inner lining tube to prevent the cut part of the inner lining tube from being cured during the initial curing.
[0029] Each old pipe clamp 32 is set to an arc shape that matches the old pipe. The distance between the inner circle of the inner fixed cover 31 and the outer surface of the old pipe is greater than the sum of the thicknesses of the old pipe clamp 32 and the adjusting screw barrel 33, and the height of the adjusting screw barrel 33 is greater than the height of the adjusting screw 34. The detachable design between the old pipe clamp 32 and the inner fixed cover 31 can be replaced and adjusted according to the diameter of the old pipe. The innermost circle diameter of the inner fixed cover 31 is equal to the outer circle diameter of the inner liner pipe.

Driven by the tube 33 and the adjusting screw 34, it fits on the outer surface of the old pipe and is clamped and fixed. The height of each limiting sleeve 36 is equal to the height of the adjusting screw tube 33, the height of each limiting slide rod 35 is equal to the height of the adjusting screw 34, and the length of each old pipe clamp 32 is smaller than the length inside the inner fixed cover 31, so as to avoid the limiting slide rod 35 and the limiting sleeve 36 affecting the normal movement of the old pipe clamp 32 and ensure that the old pipe clamp 32 can be completely separated from the inner fixed cover 31.
