Description

Technical Field

[0001] The utility model belongs to the technical field of municipal construction, and in particular relates to a combined local resin curing repair air bag. Background Art

[0002] At present, in the trenchless repair of municipal pipe network projects, local resin curing is widely used because it can repair defects in the pipeline at a single point without excavation and construction, and the road occupation time is short. However, when there are multiple defects in the same pipe section, the current local resin curing airbag can only be operated at one point at a time. The operation efficiency and road occupation time are completely dependent on the number of points that need to be repaired. Therefore, it is necessary to design a combined local resin curing repair airbag to solve the above problems. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a combined local resin curing repair airbag, which solves the problem that in the prior art, only a single airbag can be sent in for repair when performing single-point repair in a pipeline, and only one point can be operated at a time, resulting in low efficiency. The utility model has the characteristics of being able to be sent into predetermined positions separately through combined airbags, thereby achieving support for multiple repair points at the same time, and carrying out repair operations at the same time, thereby greatly improving the operating efficiency.

[0004] In order to realize the above-mentioned design, the technical solution adopted by the utility model is:

[0005] A combined local resin curing repair airbag comprises an airbag body. A plurality of airbag bodies are connected to form a combined repair airbag via a docking mechanism. The docking mechanism comprises a wire reel connected to one surface of the airbag body, and the wire reel cooperates with a pull ring connected to the other surface of the airbag body via a wire rope.

[0006] Preferably, a winding motor is provided inside the winding device, an output end of the winding motor is connected to a winding wheel, a wire rope is wound around the surface of the winding wheel, and one end of the wire rope is fixed to the winding wheel.

[0007] Preferably, the other end of the wire rope extends out of the wire reel, passes through a pull ring connected to the other side surface of the airbag body, and is hooked with a buckle connected to the surface of one side of the wire reel of the airbag body.

[0008] Preferably, the cable reel is electrically connected to an external power source via a cable; the cable is serially connected with an independent power switch.

[0009] Preferably, a plurality of pulleys are connected to the outer surface of the airbag body, and the pulleys are slidably matched with the inner wall of the pipe.

[0010] The beneficial effects of the above-mentioned combined local resin curing repair airbag are as follows:

[0011] The device solves the problem that the prior art can only send in a single airbag for repair when performing single-point repair in a pipeline, and can only perform one point operation at a time, resulting in low efficiency. The device has the characteristics of being able to send combined airbags into predetermined positions separately, thereby achieving support for multiple repair points at the same time and carrying out repair operations at the same time, greatly improving the operating efficiency.

[0015] like Figure 1~Figure 2 In the invention, a combined local resin curing repair airbag includes an airbag body 1, and a plurality of airbag bodies 1 are connected to form a combined repair airbag through a docking mechanism; the docking mechanism includes a wire reel 2 connected to the surface of one side of the airbag body 1, and the wire reel 2 cooperates with a pull ring connected to the surface of the other side of the airbag body 1 through a wire rope 3.

[0016] Preferably, a winding motor is provided inside the winding device 2, and the output end of the winding motor is connected to a winding wheel, a wire rope 3 is wound around the surface of the winding wheel, and one end of the wire rope 3 is fixed to the winding wheel.

[0017] Preferably, the other end of the wire rope 3 extends out of the wire reel 2 , passes through a pull ring connected to the other side surface of the airbag body 1 , and is hooked with a buckle 4 connected to the side surface of the wire reel 2 of the airbag body 1 .

[0018] Preferably, the cable reel 2 is electrically connected to an external power source via a cable; the cable is serially connected with an independent power switch.

When an airbag reaches the repair point, the airbag at that point is pressurized. After the pressurization is in place, the reel 2 is driven, and the second airbag immediately starts to move. After airbag No. 2 is in place, it is pressurized again to achieve simultaneous repair of multiple points.
