Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

In the related art, in the pipeline detection, dredging or non-excavation repairing process, the situation that equipment cannot pass through or a repairing device cannot be repaired due to too large pipeline deformation is often encountered, and excavation operation is generally adopted on the section of pipeline at the moment. However, when the operation area is located in important urban areas such as the city center, the life of citizens is greatly affected due to the complex pipe network, the large flow of people and the high difficulty of excavation operation.

Referring to fig. 1 and 2, the present invention provides an embodiment of a pipe rounding device, which is mainly applied to trenchless repair construction of an underground sewage pipe, and mainly aims at local collapse deformation of the pipe. The current non-excavation repair mode is various, the heavy-calibre pipeline is still better relatively, it is that adult's health can basic business turn over and can carry simple and easy repair tools, but this kind of mode is great to constructor's health injury, look for the damaged point to accomplish from getting into pipeline inspection and restoreing whole process, the workman is all the operation in a narrow and small finite space, sewage pipes buries deeply underground, the pipeline is interior to ventilate badly, often contain strong irritability or poison nature gas in the air, direct threat people's life health, and influenced by factors such as soil erosion and water loss and soil layer subside, the risk that even collapses. In pipeline repair's engineering, if the pipeline that runs into the minor bore collapses to warp and needs to repair, this kind of minor bore pipeline, people's health can't get into, firstly pipeline replacement construction in this time, secondly dig the road surface and construct, pipeline replacement construction greatly increased engineering cost, it is hard consuming time to excavate the road surface construction, construction cycle is long, and it is also great to road traffic influence simultaneously. And the pipeline of this application props circle device can be fine solution above-mentioned problem. In the following embodiments, the pipe rounding device is mainly used for rounding a pipe, and other cases requiring the pipe rounding device can be referred to.

Referring to fig. 1 to 5, in an embodiment of the pipe rounding device according to the present invention, the pipe rounding device includes a support frame 100, a support plate assembly 200, a first connecting rod assembly 300 and a driving member 400, wherein the support plate assembly 200 is mounted on the support frame 100, the support plate assembly 200 includes a first support plate 210 and a second support plate 220 opposite to each other, and the first support plate 210 and the second support plate 220 are movable in a radial direction of a pipe; the first link assembly 300 includes a first link 310, a second link 320, and a connecting portion 330 between the first link 310 and the second link 320, wherein one end of the first link 310 is hinged to the first support plate 210, the other end is hinged to the connecting portion 330, one end of the second link 320 is hinged to the second support plate 220, and the other end is hinged to the connecting portion 330; the driving member 400 is mounted on the supporting frame 100, and the driving member 400 is used for driving the connecting portion 330 to move.

Specifically, the support frame 100 functions as a frame and a housing, and the driving member 400 is fixed to the support frame 100. The choice of the driving member 400 can be many, for example, the driving member 400 can be a cylinder or an air cylinder, which is chosen according to the actual situation and is not limited herein.
