Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, and in particular to a trenchless pipeline partial repair device. Background Technology

[0002] Trenchless pipeline repair devices are used to repair localized damage, leaks, corrosion, and other defects in underground pipelines without excavating the ground. They utilize equipment such as airbag expanders and patch installers, minimizing the impact on surface traffic, the environment, and surrounding facilities. This technology is a key piece of equipment in the field of underground pipeline repair.

[0003] Existing trenchless pipeline repair devices have the following shortcomings in use: Currently, airbag expanders mainly rely on rollers at both ends to insert the expander into the pipeline, and then inflate it to make it fit tightly against the inner wall of the pipeline, thus compacting the repair material onto the inner wall of the pipeline to complete the repair and curing. However, these rollers are usually fixedly installed at both ends of the airbag expander. Since the inner diameter of different pipelines varies, the fixed rollers cannot be adaptively adjusted according to the inner diameter of the pipeline. This not only limits the applicability of the equipment, but also increases costs due to the need to equip special equipment for different pipe diameters.

[0004] Therefore, a trenchless pipeline repair device is needed to solve the above problems. Utility Model Content

[0013] As a preferred embodiment of the trenchless pipeline repair device of this utility model, the side wall of the adjusting member is provided with multiple sets of fixing holes, the fixing member passes through both sides of the adjusting seat and is inserted into the inside of the fixing holes.

[0014] In a preferred embodiment of the trenchless pipeline repair device of this utility model, the end of the fixing member is fixedly connected to a connecting member, and the connecting member is slidably connected inside the adjusting seat.

[0015] As a preferred embodiment of the trenchless pipeline repair device of this utility model, the side wall of the adjusting seat is threadedly connected to a lead screw, and the end of the lead screw is connected to a movable rod.

[0016] In a preferred embodiment of the trenchless pipeline repair device of this utility model, a side plate is fixedly connected to the outer peripheral wall of the movable rod, and the movable rod and the side plate are slidably connected inside the adjusting seat.

[0017] In a preferred embodiment of the trenchless pipeline repair device of this utility model, the side plates and the side walls of the connectors are all fixedly connected with hinges, and the hinges are rotatably connected with movable parts.

[0018] The beneficial effects of this utility model are as follows: by setting an adjustment component between the airbag dilator and the rollers, the adjustment component can be slid on the adjustment seat by moving the fixing part on the adjustment component. This makes it easy to adjust the position of multiple sets of rollers on the airbag dilator according to the size of the pipe, so that the distance between them and the inner wall of the pipe is appropriate, thus improving its applicability.

[0033] In use, by moving the fixing part 204, the adjusting part 201 can be slid on the adjusting seat 203, which makes it easy to adjust the position of the roller 101 on the airbag dilator 100 according to the size of the pipe, thus improving its applicability.

[0034] Example 2

[0035] Reference Figures 1 to 4 This is the second embodiment of the present invention. Unlike the previous embodiment, the adjusting member 201 is rotatably connected to both sides of the roller 101, and the bottom of the adjusting member 201 is fixedly connected to the slider 202. The end of the airbag dilator 100 is provided with a groove 202a, and the slider 202 is slidably connected inside the groove 202a. By slidably connecting the slider 202 inside the groove 202a, the stability of the adjusting member 201 during sliding adjustment is improved.

[0036] Multiple sets of adjustment seats 203 are fixedly connected to both ends of the airbag inflator 100 and are symmetrically distributed, while adjustment components 201 are distributed on both sides of the adjustment seats 203.

[0037] The adjusting member 201 has multiple sets of fixing holes 204a on its side wall.
