Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning, in particular to a municipal network pipe dredging device. Background Art

[0002] Municipal pipelines may become clogged during use, and they need to be cleared promptly to avoid urban flooding. Currently, air bags are often used to clean the inside of pipelines. Usually, staff enter the pipeline, install the air bag at a suitable depth, and then inflate it. After the air bag is inflated and pressed against the inner wall of the pipeline, the inflated air bag is pulled out of the pipeline through an external rope, and the blockage in the pipeline can be discharged at the same time, completing the dredging of the pipeline. Using air bags to clear blockages has the characteristic of thorough dredging. However, for some pipelines with a small inner diameter, since staff cannot drill into the pipeline to install the air bag, it is also difficult to transport the air bag to the appropriate depth by external force, resulting in difficulty in properly cleaning and clearing such pipelines.

[0028] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0029] There are two common methods used for dredging municipal networks. One involves using a negative pressure tube carried by a cleaning truck. Workers then enter the pipes and manipulate the tube to draw silt and other obstructions into the truck, which is labor-intensive. The other involves pulling an inflatable airbag to remove the silt. This inflatable airbag can completely remove obstructions, offering high efficiency and low maintenance. However, pipelines often stretch for long distances. For pipelines with a small inner diameter that are inaccessible to workers, it's impossible to place the airbag deep within the pipeline. Other methods also fail to completely remove obstructions such as silt. Therefore, the following solutions are provided.

[0030] Example 1

[0031] Using airbags to clean pipes has the characteristics of fast, efficient and thorough cleaning. However, for pipes with smaller sizes, since workers cannot enter the pipes, it is not possible to send the airbags deep into the pipes. This embodiment provides a municipal network pipe dredging device, such as Figures 1-4As shown, it covers the base 1 and the airbag 7. The base 1 is provided with several groups of heat dissipation holes, and the base 1 is installed with a connecting frame 11 for locking an external pull rope. An air pump 10 is installed in the base 1, and a hose 9 is installed between the air pump 10 and the airbag 7. The air pump 10 can inflate the airbag 7, causing it to expand and fit against the inner wall of the pipe. A rope 8 is fixed between the base 1 and the airbag 7 through a connecting seat. There are two groups of ropes 8, which are symmetrically distributed on both sides of the hose 9, and the length of the rope 8 is shorter than the length of the hose 9. Even if the rope 8 is in a straight state, it will not pull on the hose 9, avoiding tearing the hose 9. The base 1 is provided with multiple groups of retractable adjustment legs 2. Through this adjustable setting, it is ensured that the auxiliary wheel 3 and the power wheel 4 are tightly against the inner wall of the pipe.

[0032] Four groups of adjusting legs 2 are rotatably mounted on the tail end of the machine base 1, and are distributed in pairs on both sides of the machine base 1. The ends of the four groups of adjusting legs 2 facing away from the machine base 1 are equipped with auxiliary wheels 3 through mounting frames. When working, the auxiliary wheels 3 abut against the inner wall of the pipe, and the tail end of the machine base 1 is equipped with an expansion and contraction part 6 for adjusting the angle between the adjacent adjusting legs 2 on the same side (vertically on the same side); the other two groups of adjusting legs 2 are fixed on the head end of the machine base 1 and are symmetrically distributed on both sides of the machine base 1. The ends of the two groups of adjusting legs 2 facing away from the machine base 1 are equipped with power wheels 4 and a motor 5 for driving the power wheels 4 to rotate through a mounting frame, and the motor 5 is installed on the mounting frame.

[0033] In the initial state, the airbag 7 is in a deflated state and is hung at the head end of the base 1. The base 1 is placed at the pipe inlet, and by adjusting the telescopic control of the legs 2, the four sets of auxiliary wheels 3 and the two sets of power wheels 4 are tightly against the inner wall of the pipe, as shown in FIG. Figure 4 As shown. After the stand 1 is installed on the inner wall of the pipe, fix the external pull rope on the connecting frame 11, start the motor 5 to rotate the power wheel 4, and then drive the stand 1 and the rope 8 and airbag 7 connected to it to move deeper along the pipe. After moving to the appropriate position, control the stand 1 to move back a short distance to ensure that the airbag 7 is not located below the stand 1, so that the airbag 7 and the base 1 maintain a certain distance. Figure 1 Then, the air pump 10 is started, and the airbag 7 begins to inflate until the airbag 7 is in close contact with the inner wall of the pipe. Next, the external pull rope is pulled by external force, and the motor base 1 is pulled outward. The airbag 7 can be pulled out of the pipe together with the rope 8. During the pulling process, the silt and other debris in the pipe can be discharged together, thus clearing and unblocking the pipe. When faced with a pipe that is inaccessible to staff, the device in this embodiment can effectively transport the airbag 7 to the designated location. It is simple to operate and easy to use.

[0034] The most common thing in the municipal network pipe is silt, which needs to be cleaned regularly, but the degree of silt deposition in different areas is different. The expansion and contraction part 6 includes a hydraulic rod 61 installed on the machine base 1. The movable end of the hydraulic rod 61 is fixed with a moving block 62, and the connecting rod 63 symmetrically rotatably installed on the moving block 62 is connected to the corresponding adjustment leg 2. Start the hydraulic rod 61 and move the moving block 62 together, which can drive the two groups of adjustment legs 2 connected thereto to rotate outward or inward at the same time. When there is a lot of silt in the pipeline, control the adjustment leg 2 at the tail end of the machine base 1 to rotate to the following position: Figure 7 As shown in the left figure, the auxiliary wheel 3 and the power wheel 4 are guaranteed not to come into contact with the silt, but the stability of the base 1 is not good enough at this time; when there is less silt in the pipeline, the adjustment leg 2 at the tail end of the base 1 is controlled to rotate to the following position: Figure 7 As shown in the right figure, the auxiliary wheels 3 and the power wheels 4 will not come into contact with the mud, but since the support angle of the adjustment legs 2 is large, the stability of the machine base 1 during movement is improved.

[0035] Since the inner diameters of pipes in different areas are different, it is necessary to adjust the positions of the auxiliary wheels 3 and the power wheels 4 to ensure that they can abut against the inner wall of the pipe. The adjustment leg 2 set for this purpose includes a first sleeve 211, a first pull rod 212 is slidably installed in the first sleeve 211, and a locking screw 213 for locking the first pull rod 212 is installed on the first sleeve 211. Taking the case where the inner diameter of the pipe is too large as an example, the specific adjustment is as follows: loosen the locking screw 213, pull the first pull rod 212 outward, let the wheel abut against the inner wall of the pipe, and then tighten the locking screw 213. It can adapt to pipes with different inner diameters and can better meet actual usage needs.

[0036] Example 2

[0037] Same as Example 1, reference Figure 5 The difference is that the adjusting leg 2 includes a second sleeve 221, a second drawer rod 222 is slidably mounted in the second sleeve 221, and an electric push rod 223 is mounted between the second sleeve 221 and the second drawer rod 222. When the electric push rod 223 is activated, the second drawer rod 222 is driven to move, causing the wheel to abut against the inner wall of the pipe, eliminating the need for manual adjustment, simplifying operation and facilitating use, but increasing cost.

[0038] Example 3

[0039] Same as Example 1, reference Figure 6The difference is that the adjustment leg 2 includes a third sleeve 231, in which a third lever 232 is slidably mounted. A screw 233 is threadedly mounted on the third sleeve 231, and the end of the screw 233 is rotatably mounted to the third lever 232. Rotating the screw 233 drives the second lever 222 to move, allowing the wheel to abut against the inner wall of the pipe. Compared to the locking screw 213, this prevents relative movement between the third lever 232 and the third sleeve 231, resulting in better stability after adjustment.
