Embodiment Construction

[0031] The present invention will be further described with reference to the accompanying drawings.

[0032] refer to figure 1 , this embodiment discloses a kind of maintenance equipment for municipal sewage pipes, including a central rod 1, two groups of back expansion mechanisms 2 are arranged along the circumference of the central rod 1, and the two groups of back expansion mechanisms 2 are located on the two sides of the central rod 1. side. The central rod 1 is also provided with a driving member 3 for driving the re-expansion mechanism 2 to move.

[0033] refer to figure 1 , figure 2 The expansion mechanism 2 includes a expansion rod 4 with one end hinged to the central rod 1, a connecting rod 26 hinged with the other end of the expansion rod 4, and a fastening block 5 hinged at the end of the connecting rod 26 away from the expansion rod 4. A plurality of back-expansion thorns 6 are fixedly arranged on the side of the back-expansion rod 4 facing away from the conne...

Abstract

The invention discloses maintenance equipment for municipal blow-off pipes, and relates to the technical field of city building engineering construction. According to a key point of the technical scheme, the maintenance equipment comprises a center rod, a back enlarging rod and a connecting rod; and an inserting groove and a waist-type groove are formed in the center rod, wherein the inserting groove and the waist-type groove extend in the axial direction, the end, away from the back enlarging rod, of the connecting rod is inserted into the inserting groove, and a round rod which is inserted into the waist-type groove is fixedly arranged on the connecting rod. The maintenance equipment further comprises a driving piece which is used for driving the round rod on the connecting rod to move in the length direction of the waist-type groove, a placing groove and a thread groove communicating with the placing groove are formed in the center rod, and the thread groove communicates with the inserting groove. The driving piece comprises a rotating ring which is in threaded connection with the interior of the thread groove, one end of the rotating ring extends to the outside of the thread groove, and the other end of the rotating ring applies force moving in the length direction of the waist-type groove on the connecting rod. According to the maintenance equipment for the municipal blow-off pipes, the weight of a whole back enlarging device is reduced, energy required to work is reduced, and the problem that an air cylinder, a hydraulic cylinder and the like are prone to being damaged is further solved.

Description

technical field [0001] The invention relates to the technical field of urban building engineering construction, more specifically, it relates to a maintenance equipment for municipal sewage pipes. Background technique [0002] Municipal pipeline engineering is an important part of municipal engineering and an important infrastructure engineering facility in a city. Municipal sewage pipes are mainly used for the collection and discharge of domestic sewage and industrial sewage. After a long period of use, the pipes will be deformed and damaged, requiring maintenance. [0003] In the prior art, a Chinese patent document with the application publication number CN108222221A discloses a maintenance process for municipal sewage pipelines, using equipment to break or split the original pipeline from the inside, and squeeze the original pipeline fragments into the surrounding soil At the same time, the pipe hole is formed, and the pipe of the new pipe is pulled in synchronously to...
