Description

Technical Field

[0001] The utility model relates to a dredging device in a pipeline of an underground pipe network, in particular to a dredging roller with a pneumatic system assisting in steering. Background Art

[0002] There are a lot of cement, steel bars or stones blocking the underground pipe network, and traditional cleaning tools cannot clean it at all. Later, shield machines were used for cleaning. The shield machine's cutter head rotates to clean the above blockages; although it can be cleaned, it is also quite laborious. In addition, the shield machine's cutter head cannot turn, so it is often easy to turn off.

[0003] At present, the dredging roller is installed at the front end of the dredging manipulator, most of which cannot turn and can only move along the pipeline, affecting the dredging effect.

[0004] In recent years, double rollers have appeared; although they can turn in square channels, they cannot turn in circular pipes. Utility Model Content

[0005] Aiming at the problem that the existing dredging roller cutter cannot turn in a circular pipe, the utility model aims to provide a dredging roller cutter with a pneumatic system assisting in turning.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] The utility model comprises a roller cutter frame and a roller cutter system installed at the front end of the roller cutter frame, wherein at least one group of left pneumatic steering system and right pneumatic steering system are respectively installed on the roller cutter frame, the left pneumatic steering system and the right pneumatic steering system of each group have the same structure, both comprise a cylinder, a transition plate and a push plate, the cylinder is installed in the roller cutter frame, the output ends of the cylinders in the left pneumatic steering system and the right pneumatic steering system of each group respectively pass through the left and right sides of the roller cutter frame, the output end of the cylinder is connected to one end of the transition plate, and the other end of the transition plate is connected to the push plate; an observation system for conveniently controlling the steering of the dredging roller cutter is installed on the roller cutter frame.

[0008] Wherein: the observation system includes a detection light and a camera respectively installed on the hob frame.

[0009] A buoyancy box is provided on the roller cutter frame, the rear end of the buoyancy box is hinged to the roller cutter frame, the detection light and the camera are respectively installed on the front end of the buoyancy box, and the detection light and the camera are brought out of the water through the buoyancy box when working.

[0010] The left pneumatic steering system and the right pneumatic steering system form a group and are arranged side by side in the hob frame, or are respectively arranged at the front and rear ends of the hob frame.

[0011] The left pneumatic steering system and the right pneumatic steering system are divided into two groups. The left pneumatic steering system and the right pneumatic steering system of the first group are located at the front and rear ends of the hob frame, and the left pneumatic steering system and the right pneumatic steering system of the second group are located between the left pneumatic steering system and the right pneumatic steering system of the first group. The left pneumatic steering system and the right pneumatic steering system of each group work synchronously.

[0012] The output directions of two adjacent pneumatic steering systems are opposite.

[0013] The advantages and positive effects of the utility model are:

[0014] 1. The utility model can make a turn in a circular pipe according to the desilting needs in the circular pipe through detection by an observation system. The desilting can be done part by part, first cleaning the middle and then cleaning the left and right sides. If an obstacle is encountered, the utility model can also turn to bypass the obstacle.

[0015] 2. The left and right pneumatic steering systems of the utility model can be multiple groups, which can increase the steering torque, make the steering faster, and increase the steering range.

[0016] 3. The detection light and camera used for observation in the utility model can float on the water surface through a buoyancy box. BRIEF DESCRIPTION OF THE DRAWINGS

At least one group of left pneumatic steering system 4 and right pneumatic steering system 5 are respectively installed on the roller cutter frame 2. The left pneumatic steering system 4 and the right pneumatic steering system 5 of each group have the same structure and include a cylinder 6, a transition plate 7 and a push plate 8. The cylinder 6 is installed in the roller cutter frame 2. The output ends of the cylinder 6 in the left pneumatic steering system 4 and the right pneumatic steering system 5 of each group pass through the left and right sides of the roller cutter frame 2 respectively. The output end of the cylinder 6 is connected to one end of the transition plate 7, and the other end of the transition plate 7 is connected to the push plate 8; the roller cutter frame 2 is installed with an observation system for controlling the steering of the dredging roller cutter. The roller cutter system 1 of this embodiment is a prior art and will not be described in detail here.

[0030] The left pneumatic steering system 4 and the right pneumatic steering system 5 of this embodiment are a group, arranged side by side in the cutter frame 2, or respectively arranged at the front and rear ends of the cutter frame 2; one left pneumatic steering system 4 and one right pneumatic steering system 5 of this embodiment are arranged side by side in the middle position of the cutter frame 2. The cylinder 6 in the left pneumatic steering system 4 and the cylinder 6 in the right pneumatic steering system 5 are respectively connected to the external control air circuit, and the operation is controlled by the control air circuits connected to them.

[0031] The observation system of this embodiment includes a detection light 9 and a camera 10.

[0035] When the dredging roller is working in a circular pipe, the observation video results fed back to the control system by the detection light 9 and the camera 10 are used to determine the moving working direction of the dredging roller. The control system starts the control air circuit to make the cylinder 6 in the left pneumatic steering system 4 and the cylinder 6 in the right pneumatic steering system 5 of the first group work at the same time, or make the cylinder 6 in the left pneumatic steering system 4 and the cylinder 6 in the right pneumatic steering system 5 of the second group work at the same time, and drive the push plate 8 to move radially along the circular pipe through the transition plate 7, so that the push plate 8 contacts the inner wall of the circular pipe, and the reaction force of the inner wall of the circular pipe pushes the dredging roller to partially turn, thereby achieving the purpose of dredging.
