Description

Technical Field

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

[0002] Municipal pipelines are an important part of urban infrastructure. Timely and effective maintenance and repair can extend the service life of the pipelines, especially sewage pipes, which are mainly used to collect and transport liquid wastes such as domestic sewage, industrial wastewater and rainwater. Since these wastes are corrosive, they need to be located, maintained and repaired. When a part of the pipeline is damaged, the water inlet of the broken pipe needs to be blocked, and the water flow bypasses the broken pipe and is introduced into the next intact pipe. In conventional operations, an inflatable airbag is usually used to block the water flow. The sewage passes through the pipe rack and the flow rate is controlled by a valve, so that the sewage is transported to the intact sewage pipe. However, there may be mud or other impurities in the sewage pipe, which will cause blockage of the pipe rack, which is not conducive to the smooth progress of the sewage pipe repair work.

[0003] In view of the above problems, a municipal pipeline maintenance and repair device is now developed. Utility Model Content

However, there may be mud or other impurities in the sewage pipe, which will cause blockage of the pipe rack and hinder the smooth progress of the sewage pipe repair work. The utility model provides a municipal pipeline maintenance and repair device.

[0006] Further description is made, and a limiting member is included. The front side of the lower part of the through-tube rack is connected to the limiting member. A contact frame is slidably connected to the limiting member. A spring is connected between the contact frame and the limiting member.

[0007] It is further explained that the contact members are all arranged in a staggered manner, and the contact members can play a protective role for the inflatable airbag.

[0008] It is further explained that the rear side of the stirring plate is a sloped structure, which can reduce the resistance during stirring.

[0009] It is further explained that a protective frame is provided on the driving wheel to make the stirring plate more stable.

[0010] It is further explained that the movement of the stirring disc can vibrate the sewage to prevent sludge or other impurities from clogging the pipe rack.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0018] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0019] A municipal pipeline maintenance and repair device, such as Figures 1-4As shown, it includes an inflatable airbag 1, a plurality of contact members 2 are connected to the inflatable airbag 1, the contact members 2 are staggered and arranged, and the contact members 2 can protect the inflatable airbag 1. An air inlet 3 is opened on the front side of the inflatable airbag 1, a pipe rack 4 is connected to the inflatable airbag 1, a valve 5 is connected to the front of the pipe rack 4, a drive motor 6 is installed on the front left side of the pipe rack 4, a rotating shaft 7 is connected to the output shaft of the drive motor 6, a drive wheel 8 is rotatably connected to the rear side of the rotating shaft 7, and a plurality of cylindrical bumps are provided on the drive wheel 8. The middle rear side of the pipe rack 4 is rotatably connected to a stirring disc 9, and the rear side of the stirring disc 9 is a slope mechanism, which can reduce the resistance during stirring. The stirring disc 9 is provided with a number of grooves, which can engage with adjacent cylindrical protrusions. A protective frame is provided on the driving wheel 8 to make the stirring disc 9 more stable. The movement of the stirring disc 9 can vibrate the sewage to prevent sludge or other impurities from clogging the pipe rack 4. The front side of the lower part of the pipe rack 4 is connected to a limiting member 10, and a contact frame 11 is slidably connected to the limiting member 10. A spring 12 is connected between the contact frame 11 and the limiting member 10.

[0020] It should be noted that municipal pipelines are an important part of urban infrastructure. Timely and effective maintenance and repair can extend the service life of pipelines, especially sewage pipes, which are mainly used to collect and transport liquid wastes such as domestic sewage, industrial wastewater and rainwater. Since these wastes are corrosive, they need to be located, maintained and repaired. When a certain part of the pipeline is damaged, it is necessary to block the water inlet of the broken pipeline, bypass the broken pipeline, and introduce the water flow into the next intact pipeline. This device, as a medium for sewage transportation, can transport sewage to another intact pipeline. First, the inflatable airbag 1 is placed at the position that needs to be blocked, and the inflatable airbag 1 is inflated using the air inlet 3. The inflatable airbag 1 blocks the sewage. The contact pieces 2 are staggered and can be applied to each inflation stage of the inflatable airbag 1. At the same time, the inflatable airbag 1 is protected to prevent sharp objects from damaging the inflatable airbag 1 during the repair process. Sewage flows from the back side of the pipe rack 4 to the front The conveying frame is connected to the intact conveying pipe on the front side, and the sewage flow rate is controlled by the valve 5. In order to prevent the pipe frame 4 from being blocked by mud or other impurities, the driving motor 6 can be started. The output shaft of the driving motor 6 rotates to drive the rotating shaft 7 to rotate, and then drives the driving wheel 8 to rotate, which will make the stirring plate 9 rotate. The movement of the stirring plate 9 can vibrate the sewage, thereby preventing the pipe frame 4 from being blocked. The inclined mechanism on the rear side of the stirring plate 9 can reduce the resistance of the stirring plate 9 during stirring. In order to enhance the stability of the device during operation, the contact piece 2 contacts the ground, thereby enhancing the force point of the device, which is beneficial to enhance the stability of the device, thereby assisting the operator to carry out the repair work smoothly. When the contact frame 11 contacts the ground, the spring 12 will be compressed by force, and the limit piece 10 limits the contact piece 2, so that the contact frame 11 assists in supporting the device. After use, under the action of the spring 12, the contact frame 11 is reset downward.

[0021] It should be understood that the above description is only for illustrative purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be within the scope of the claims herein.
