Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0029] Please refer to Figures 1-6 The utility model provides a technical scheme:

[0030] The utility model provides a kind of municipal gas pipeline protection device, including box 1, the box 1 is arranged as circle, the box 1 side is fixedly installed with evenly distributed sleeve rod 2, the sleeve rod 2 is slidably provided with movable rod 3, the movable rod 3 outer end is evenly provided with movable mouth 4, the movable mouth 4 is provided with spring 5, the movable rod 3 is slidably provided with abutment rod 6 on movable mouth 4, the spring 5 both ends are fixedly installed with movable rod 3 and abutment rod 6, the abutment rod 6 outer end is provided with abutment plate 7, the abutment plate 7 is arranged as arc, the box 1 and sleeve rod 2 are provided with driving piece 8 for driving abutment plate 7 away from each other, the driving piece 8 includes rotating knob 81 rotatingly arranged in the side of box 1, conical gear one 82 rotatingly arranged in the box 1, conical gear two 83 rotatingly arranged in the evenly distributed sleeve rod 2 in the box 1 and screw rod 84 rotatingly arranged in the sleeve rod 2 respectively, the rotating knob 81 rotation axis end is fixedly installed with the rotation axis end of conical gear one 82, the conical gear two 83 is arranged group number same with abutment plate 7, and conical gear two 83 is all meshing transmission connection with conical gear one 82, the screw rod 84 rotation axis end is fixedly installed with the rotation axis end of conical gear two 83 respectively, the movable rod 3 is screw connection with screw rod 84 respectively.

[0031] When the municipal gas pipeline protection device is used, the operator places the device vertically in the pipeline, then rotates the rotating knob 81 on the side of the box 1 to drive the conical gear one 82 to rotate in the box 1. Since the conical gear one 82 is meshing transmission connection with multiple sets of conical gear two 83, the conical gear one 82 drives multiple conical gear two 83 to rotate synchronously when it rotates. Since the rotation axis end of the conical gear two 83 is fixedly installed with the screw rod 84, the conical gear two 83 drives multiple sets of screw rod 84 to rotate in the sleeve rod 2 simultaneously when it rotates. Since the movable rod 3 is screw connection with the screw rod 84, the movable rod 3 slides along the sleeve rod 2 to the inner wall of the pipeline under the condition that the screw rod 84 rotates. During the sliding process of the movable rod 3, the abutment rod 6 and the abutment plate 7 move to the inner wall of the pipeline synchronously. When the abutment plate 7 is in close contact with the inner wall of the pipeline, the pipeline is protected. Since there is a spring 5 between the abutment rod 6 and the movable rod 3, the spring 5 will stretch or contract according to the size of the inner diameter of the pipeline when the abutment plate 7 is squeezed to different degrees by pipelines with different diameters, so that the abutment plate 7 can adapt to pipelines with different diameters. During the adjustment of the rotating knob 81, the contact pressure of the abutment plate 7 with the inner wall of the pipeline can be controlled. By changing the compression degree of the spring 5 in the movable mouth 4, the protection pressure on the pipeline can be adjusted, and the protection of the pipeline from the inside is realized. The municipal gas pipeline protection device realizes the protection of the pipeline from the inside. It is not only suitable for pipelines with different diameters, but also can adjust the protection pressure on the pipeline, effectively ensures the stability of the pipeline, and the overall structure of the device is simple, easy to operate and practical.

[0032] The latch 9 is arranged on the rotating handle 81, and the box body 1 is provided with the uniformly distributed sockets 10 on the side close to the latch 9, the latch 9 is matched with the socket 10, and the damping is arranged between the latch 9 and the socket 10;

[0033] After the device is installed into the pipeline and the abutting operation to the inner wall of the pipeline is completed, the latch 9 on the rotating handle 81 is inserted into the socket 10 on the box body 1, the latch 9 is matched with the socket 10, and the damping is arranged between the latch 9 and the socket 10, when the latch 9 is inserted into the socket 10, the damping can increase the friction between the latch 9 and the socket 10, so that the latch 9 is prevented from being easily pulled out of the socket 10, the rotating handle 81 can be locked at the current position by the matching of the latch 9 and the socket 10, the position of the abutting plate 7 is prevented from being changed due to the accidental rotation of the rotating handle 81, so that the protection effect of the device on the pipeline is stable, and the protection performance of the whole device on the pipeline is prevented from being affected due to the loosening of the rotating handle 81.

[0034] The surface of the abutting plate 7 is paved with the rubber pad;

[0035] The surface of the abutting plate 7 is paved with the rubber pad, the rubber pad has good elasticity and wear resistance, can be closely attached to the inner wall of the pipeline, reduces the damage caused by friction, and the rubber pad can also increase the friction between the abutting plate 7 and the inner wall of the pipeline, so that the protection device is prevented from sliding in the pipeline, and the stability of the device is further improved, in addition, the rubber pad can also play a buffering role, and reduces the impact on the protection device caused by the pressure change in the pipeline.

[0036] The abutting plate 7 is clamped on the outer end of the abutting rod 6;

[0037] The abutting plate 7 is clamped on the outer end of the abutting rod 6, so that the bottom plate of different sizes can be simply replaced according to the inner diameter of the pipeline.

[0038] Working principle:

[0039] When the pipeline protection device for municipal gas is used, the operator places the device vertically in the pipeline, then rotates the handle 81 on the side of the box body 1 to drive the bevel gear one 82 to rotate in the box body 1. Since the bevel gear one 82 is in meshing transmission connection with multiple bevel gear twos 83, the bevel gear one 82 drives the multiple bevel gear twos 83 to rotate synchronously. The rotating shaft end of the bevel gear two 83 is fixedly installed with the lead screw 84, so the bevel gear two 83 drives the multiple lead screws 84 to rotate in the sleeve rod 2 at the same time. The movable rod 3 is in threaded connection with the lead screw 84, and under the condition that the lead screw 84 rotates, the movable rod 3 slides along the sleeve rod 2 to the inner wall of the pipeline. In the sliding process of the movable rod 3, the abutting rod 6 drives the abutting plate 7 to move to the inner wall of the pipeline at the same time. When the abutting plate 7 tightly abuts against the inner wall of the pipeline, the pipeline is protected. Since there is the spring 5 between the abutting rod 6 and the movable rod 3, when the abutting plate 7 is extruded by the pipeline of different diameters to different degrees, the spring 5 will stretch or contract accordingly according to the size of the inner diameter of the pipeline, so that the abutting plate 7 can adapt to the pipeline of different diameters. In the process of adjusting the handle 81, the contact pressure of the abutting plate 7 with the inner wall of the pipeline can be controlled. By changing the compression degree of the spring 5 in the movable port 4, the protection pressure on the pipeline is adjusted, and the protection of the pipeline from the inside of the pipeline is realized. The pipeline protection device for municipal gas realizes the protection of the pipeline from the inside of the pipeline, which is not only suitable for pipelines of different diameters, but also can adjust the protection pressure of the pipeline, effectively ensures the stability of the pipeline, and the overall structure of the device is simple, easy to operate and practical.

[0040] Among them,

[0041] After the device is installed in the pipeline and the abutting operation to the inner wall of the pipeline is completed, at this time, the latch 9 on the handle 81 is inserted into the socket 10 on the box body 1. The latch 9 is matched with the socket 10, and a damping is arranged between the two. When the latch 9 is inserted into the socket 10, the damping can increase the friction between the latch 9 and the socket 10 to prevent the latch 9 from easily coming out of the socket 10. By matching the latch 9 with the socket 10, the handle 81 can be locked at the current position to avoid the position of the abutting plate 7 changing due to accidental rotation of the handle 81, thereby ensuring the stability of the protection effect of the device on the pipeline and avoiding affecting the protection performance of the entire device on the pipeline due to loosening of the handle 81.

[0042] The surface of the abutting plate 7 is paved with a rubber pad. The rubber pad has good elasticity and wear resistance, can tightly abut against the inner wall of the pipeline, reduces damage caused by friction, and increases the friction between the abutting plate 7 and the inner wall of the pipeline to prevent the protection device from sliding in the pipeline, thereby further improving the stability of the device. In addition, the rubber pad can also play a buffering role to reduce the impact on the protection device caused by the change of the internal pressure of the pipeline.

[0043] The abutting plate 7 is clamped on the outer end of the abutting rod 6, and different sizes of the bottom plate can be simply replaced according to the inner diameter of the pipeline.

[0044] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
