Description

Technical Field

[0001] The present invention belongs to the technical field of sewer pipeline repair devices, and particularly relates to a sewer pipeline repair device for cities. Background Art

[0002] Sewer pipelines are urban public facilities mainly used to convey sewage discharged from buildings and guide rainwater. With the development of cities, urban sewer pipelines have become intricate. When a sewer pipeline is damaged, sewage and wastewater will leak out, easily polluting the environment. Therefore, when a sewer pipeline is damaged, it needs to be repaired in time. There are two repair methods. One is replacement repair, that is, removing the damaged sewer pipeline and then placing a sound sewer pipeline in the original pipeline position for replacement. When using this repair method, it is necessary to dig up the ground above the pipeline before repair. Therefore, this repair method not only has low efficiency but also extremely high repair costs, and is only adopted when the damaged area of the pipeline is extremely large. Therefore, when the damaged area of the pipeline is relatively small, waterproof foaming glue is sprayed. The damaged part of the sewer pipeline is repaired by filling the damaged part of the sewer pipeline with waterproof foaming glue. After the maintenance personnel spray the waterproof foaming glue on the sewer pipeline and wait for the waterproof foaming glue to dry thoroughly, the repair of the sewer pipeline is completed.

[0003] Although the above method can repair the sewer pipeline, since the waterproof foaming glue is not shaped by other structures, due to gravity, the waterproof foaming glue will flow downward after spraying, making the area above the sprayed waterproof foaming glue in the sewer pipeline thinner, easily causing secondary damage, increasing the probability of rework and the difficulty of repair in the later stage, and reducing the repair efficiency. Summary of the Invention

[0008] Preferably, a second thread groove is formed on a side of the extension rod opposite to the first screw rod; a second screw rod is screwed and connected inside the second thread groove; and a bottom rod is fixedly connected to one end of the second screw rod opposite to the extension rod.

[0009] Preferably, a mounting cavity is formed at one end of the bottom rod opposite to the second screw rod; a first spring is fixedly connected to the interior of the mounting cavity; and a free end of the first spring is fixedly connected to the bottom plate.

[0010] Preferably, four first limiting rods are fixedly connected in a ring array on the side close to the first spring; and a first guide groove matching the first limiting rod is formed on the bottom rod.

[0011] Preferably, a first side hole is formed on the outer side of the base rod; a second side hole is formed on the outer side of the extension rod; auxiliary parts are screwed and connected inside the second side hole and the first side hole, and the auxiliary parts are used to abut against the inner wall of the pipeline.

[0012] Preferably, the auxiliary component comprises a first connecting rod; one end of the first connecting rod is fixedly connected to a side rod; and one end of the side rod opposite to the first connecting rod is fixedly connected to a connecting groove.

[0017] (2) On the basis of the above beneficial effects, the present invention is screwed and connected by the first screw rod and the second thread groove on another extension rod. According to the above steps, the extension rods required by the maintenance personnel are connected end to end, and the length-adjusted extension rod is screwed and connected with the first thread groove on the base rod through the first screw rod, so as to adjust the length of the device. By the extension rod abutting against the inner wall of the pipeline, the arc-shaped frame is further fixed, making the device easy to be fixed in pipelines with different diameters, increasing the use range of the device, and further improving the repair efficiency.

[0018] (3) On the basis of the above beneficial effects, after adjusting the length of the device, when the device needs to be fixed on the inner wall of the pipeline, if the device cannot abut against the inner wall of the pipeline and cannot be connected to another extension rod, the bottom rod is fixed on one side of the extension rod by screwing and connecting the second screw rod and the second thread groove. The first spring is supported by the installation cavity on the bottom rod, and the bottom plate is supported by the first spring. After placing the bottom plate on the inner wall of the pipeline, the bottom plate is pushed by the extrusion of the first spring, so that the bottom plate abuts against the inner wall of the pipeline, making the device easy to adjust according to the pipeline diameter, further increasing the use range of the device, and further improving the repair efficiency.

[0019] (4) On the basis of the above beneficial effects, the present invention is screwed and connected by the first connecting rod and the connecting groove on another side rod. According to the above steps, the side rods required by the user are connected end to end, so as to adjust the length of the side rods. The length-adjusted side rods are fixed on the base rod and the extension rod by screwing and connecting the first connecting rod with the first side hole and the second side hole. By the side rod abutting against the inner wall of the pipeline and the other end of the side rod supporting the base rod and the extension rod, the device is more stable when supporting the arc-shaped frame, and the stability of the device during use is improved.

[0020] (5)On the basis of the above beneficial effects, when the present invention supports the base rod and the extension rod through the side rod, if the length of the side rod is adjusted and the side rod cannot abut against the inner wall of the pipeline and cannot be connected to another side rod, the auxiliary rod is screwed and connected to the connecting groove through the second connecting rod, so that the auxiliary rod is fixed on one side of the side rod. The auxiliary rod supports the second spring and the side plate, and the side plate abuts against the inner wall of the pipeline, so that when the side rod supports the base rod and the extension rod, it can also be adjusted according to the pipeline, further improving the stability during the installation of the arc-shaped frame and further enhancing the stability of the device during use.
