[0018] Figures 1-2 The present application is a kind of whole structure schematic diagram of the lining pipe anti-damage isolation pushing device for water supply pipe repair, please refer to Figures 1-2 The lining pipe anti-damage isolation pushing device for water supply pipe repair in the embodiment comprises an arc-shaped cloth 100, the arc-shaped cloth 100 extends to the length direction of the inside of the water supply pipe, a plurality of equidistantly distributed arc-shaped skeletons 110 are fixed on the inner arc surface of the arc-shaped cloth 100 along the length direction of the arc-shaped cloth 100, a protective pad 200 covering the arc-shaped skeletons 110 is further arranged on the inner side of the arc-shaped cloth 100, a plurality of rope belts 300 are arranged on the outer side of the arc-shaped cloth 100 along the length direction of the arc-shaped cloth 100, a plurality of pulley fasteners 400 are fixed on the side of the rope belts 300 away from the arc-shaped cloth 100, and the plurality of pulley fasteners 400 are uniformly distributed along the length direction of the rope belts 300.

[0019] The diameter of the arc-shaped pad cloth 100 is smaller than the inner diameter of the water supply pipe, and the pulley fastener 400 is in contact with the inner wall of the water supply pipe. It can be understood that the diameter of the arc-shaped pad cloth 100 is smaller than the inner diameter of the water supply pipe, so that the pushing device is easier to enter the water supply pipe. The inner arc surface of the protective pad 200 is covered with a fur skin, and the protective pad 200 is fixedly attached to the inner side of the arc-shaped pad cloth 100. The inner arc surface of the protective pad 200 covered with a fur skin can effectively protect the inner lining pipe, so that the arc-shaped pad cloth 100 will not scratch the surface of the inner lining pipe when it is pulled out; it should be noted that the detachable connection between the protective pad 200 and the arc-shaped pad cloth 100 is preferred, such as button connection, binding connection, etc., so as to facilitate disassembly. The pulley fastener 400 includes a U-shaped frame 410 fixed to one side of the rope belt 300, a pulley 420 located inside the U-shaped frame 410, and a rotating shaft 430 coaxially fixed to both sides of the pulley 420 and rotatably installed inside the U-shaped frame 410. It can be understood that when the inner lining pipe is pulled in the water supply pipe to be repaired, the pulley 420 on one side is in sliding abutment with the inner side wall of the water supply pipe, which can cooperate with the arc-shaped pad cloth 100 and protect and isolate the inner side wall of the inner lining pipe from the inner side wall of the water supply pipe, thereby avoiding scratching and scratching the inner wall of the water supply pipe, and also making the arc-shaped pad cloth 100 more linear and labor-saving when being pulled; it should be noted that the inner lining pipe is flat when put into the inner side of the arc-shaped pad cloth 100, i.e. in the unexpanded state, so the inner lining pipe is laid in the inner side of the arc-shaped pad cloth 100; specifically, in this embodiment, the inner lining pipe is put into the inner side of the arc-shaped pad cloth 100 and laid along the length direction, and then one end of the arc-shaped pad cloth 100 is pulled by a rope or other pulling means, so that the arc-shaped pad cloth 100 gradually enters the water supply pipe. During the pulling process, the arc-shaped pad cloth 100 can protect and isolate the outer side wall of the inner lining pipe from the inner side wall of the water supply pipe under the cooperation of the pulley 420, so as to prevent the inner wall of the water supply pipe and the attached rust from scratching and damaging the outer side wall of the inner lining pipe, and also make the device more linear and labor-saving when being pulled. After the position of the inner lining pipe is determined, the other end of the inner lining pipe can be fixed and the arc-shaped pad cloth 100 can be continuously pulled out. At this time, under the cooperation of the protective pad 200, the arc-shaped pad cloth 100 and the skeleton can be prevented from scratching the surface of the inner lining pipe when being pulled out, so that the laying of the inner lining pipe in the pipe can be completed, the quality of the inner lining pipe is guaranteed, and the repair and installation work is facilitated.

[0020] As a preferred, further, the rope belt 300 is made of nylon material, and the rope belt 300 is half covered on the outside of the U-shaped frame 410. The nylon material has the characteristics of high tensile strength, wear resistance and good corrosion resistance, which can improve the overall strength of the arc-shaped pad cloth 100 and the pushing device. It should be noted that the U-shaped frame 410 and the rope belt 300 can be adhesively connected, sewn, etc.

[0021] As preferred, further, the arc-shaped cushion 100 adopts polyethylene or polyester fiber material, and the arc-shaped framework 110 adopts engineering plastic or stainless steel material. It can be understood that the cushion made of polyethylene or polyester fiber has the characteristics of wear resistance, corrosion resistance, waterproofness, easy cleaning, etc. In addition, the engineering plastic or stainless steel material has the characteristics of light weight and high mechanical strength, and can shape and support the arc-shaped cushion 100 and make the pulley fastener 400 close to the water supply pipe.

[0022] In summary, the inner lining pipe damage-preventing isolation and pushing device for repairing water supply pipe of the embodiment can be used by placing the inner lining pipe inside the arc-shaped cushion 100 and laying along the length direction of the arc-shaped cushion 100, then pulling one end of the arc-shaped cushion 100 through the pulling means such as a rope, so that the arc-shaped cushion 100 gradually enters the water supply pipe. During the pulling process, the arc-shaped cushion 100 can protect and isolate the outer side wall of the inner lining pipe from the inner side wall of the water supply pipe under the cooperation of the pulley 420, so as to prevent the inner wall of the water supply pipe and the attached rust from scratching and damaging the outer side wall of the inner lining pipe. At the same time, the device is more linear and labor-saving during pulling. After the position of the inner lining pipe is determined, the other end of the inner lining pipe can be fixed and the arc-shaped cushion 100 can be continuously pulled out. At this time, the arc-shaped cushion 100 and the framework can be prevented from scratching the surface of the inner lining pipe during pulling out under the cooperation of the protective pad 200. Until the arc-shaped cushion 100 is completely pulled out, the inner lining pipe can be placed in the pipe, which ensures the quality of the inner lining pipe and brings convenience to the repair and installation work.
