Description

Technical Field

[0001] The utility model relates to the technical field of municipal maintenance, in particular to a maintenance device for municipal pipelines. Background Art

[0002] In municipal engineering, pipeline inspection and maintenance is a common operation in municipal construction. When users inspect pipelines, they need to drill into the pipelines to inspect them. However, the existing municipal pipelines have different sizes in different installation environments, which results in the inspection equipment being unable to effectively inspect the pipelines according to the size of the pipelines during inspection.

[0003] The existing authorized patent number is CN 215060450 U, which is a municipal pipeline maintenance device, including a mobile vehicle and a detection device. The mobile vehicle is provided with a motor and a lifting column. The detection device is arranged on the lifting column and can be moved up and down with the lifting column. A transmission mechanism is connected between the motor and the lifting column, and the motor drives the lifting column to move up and down on the mobile vehicle through the transmission mechanism.

[0004] The above-mentioned equipment has a reasonable structure. The height of the lifting column is quickly adjusted by a motor, thereby adjusting the working height of the detection equipment, so that the working height of the detection equipment is matched with the size of the municipal pipeline, thereby avoiding the inability of the maintenance equipment to enter the municipal pipeline due to the working height of the detection equipment being too high, so that the maintenance equipment can smoothly enter the municipal pipeline for maintenance work. However, the existing municipal pipeline maintenance equipment can only adjust the height in the pipeline and cannot maintain a fit with the inner wall of the pipeline. Because the inner wall of the pipeline is cylindrical, the maintenance device is unstable during the movement process, and it is difficult to carry out stable maintenance work. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 6 A municipal pipeline maintenance device comprises a connecting rod 1, one end of which is fixedly connected to a first annular fixing block 2, one side outer wall of the first annular fixing block 2 is fixedly connected to a threaded rod 3, and one end of the threaded rod 3 is fixedly connected to a limiting block 4;

[0028] The other end of the connecting rod 1 is fixedly connected to a second annular fixing block 5 , one side outer wall of the second annular fixing block 5 is fixedly connected to a positioning block 6 , and one side outer wall of the positioning block 6 is fixedly connected to a Hall sensor 20 .

[0029] The first annular fixing block 2 is connected by the connecting rod 1, and the connecting rod 1 and the threaded rod 3 form a whole through the first annular fixing block 2. The position of the connecting block 12 is limited by the limit block 4. The first connecting strip 9 on the outer wall of the second annular fixing block 5 can be positioned by the positioning block 6. The condition of the inner wall of the pipeline can be fed back to the external receiver in real time through the Hall sensor 20, which is convenient for subsequent further maintenance.

[0030] The outer wall of the first annular fixing block 2 is fixedly connected with a first fixing block 7 , the interior of the first fixing block 7 is rotatably connected with a first rotating shaft 8 , and both ends of the first rotating shaft 8 are rotatably connected with first connecting bars 9 .

[0031] The first rotating shaft 8 can be rotated by the first fixing block 7 , and the first connecting bar 9 also moves along with the first rotating shaft 8 during the rotation.

[0032] A second rotating shaft 10 is rotatably connected to an outer wall of one side of the first connecting strip 9 , and a T-shaped plate 11 is rotatably connected to an outer wall of the second rotating shaft 10 .

[0033] The first connecting bar 9 is displaced by the rotation of the second rotating shaft 10 and causes the T-shaped plate 11 to move outward.

[0034] A connecting block 12 is disposed on one side outer wall of the first annular fixing block 2 , a threaded hole 13 is formed on the inner wall of the connecting block 12 , and the threaded hole 13 is threadedly connected to the threaded rod 3 .

[0035] Through the threaded connection between the threaded hole 13 and the threaded rod 3 , the connecting block 12 can be horizontally moved by the rotation of the threaded rod 3 .

[0036] An annular groove 14 is formed on the outer wall of the connecting block 12, and a third annular fixing block 15 is rotatably connected to the inner wall of the annular groove 14, and a second fixing block 16 is fixedly connected to the outer wall of the third annular fixing block 15, and a third rotating shaft 17 is rotatably connected inside the second fixing block 16, and second connecting bars 18 are rotatably connected to both ends of the third rotating shaft 17.

[0037] When the connecting block 12 rotates through the threaded rod 3 to perform horizontal movement, the third annular fixing block 15 will also move horizontally synchronously, causing the second connecting strip 18 to drive the position of the T-shaped plate 11 to change. The position of the T-shaped plate 11 will increase from low to high until the connecting strip on the second annular fixing block 5 contacts the positioning block 6, and the horizontal movement is hindered, and the displacement of the T-shaped plate 11 stops. At this time, the T-shaped plate 11 moves to the limit height.

[0040] An anti-skid wheel 21 is fixedly connected to the top of the T-shaped plate 11 , and a blocking plate 22 is fixedly connected to the outer wall of the anti-skid wheel 21 .

[0041] The anti-skid wheel 21 can prevent the inspection device from slipping when running in the pipeline, and the blocking plate 22 can prevent the anti-skid wheel 21 from being blocked by impurities attached to the inner wall of the pipeline during movement.

[0042] Working principle: when using the new municipal pipeline maintenance device, place the maintenance device in the municipal pipeline, through the threaded connection between the threaded hole 13 and the threaded rod 3, rotate the connecting block 12 to move in the horizontal direction, and while the connecting block 12 is moving, the third annular fixing block 15 on the outer wall of the connecting block 12 also moves horizontally synchronously. During the movement, the first connecting strip 9 and the second connecting strip 18 increase the height of the T-shaped plate 11 from low to high, which can adapt to municipal pipelines of different radii, so that the maintenance device can maintain an adaptive fit with the inner wall of the municipal pipeline, and the anti-skid wheel 21 can keep the pipeline maintenance device stable during the movement and not prone to slipping, and the blocking plate 22 can prevent the anti-skid wheel 21 from being blocked by impurities attached to the inner wall of the pipeline during the movement.
