DETAILED DESCRIPTION

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0022] See also Figure 1-4 As shown, a pipeline positioning device for municipal engineering includes a pushing mechanism 1, which is composed of a forward and reverse dual-axis motor, a rotating rod and a first bevel gear and other structures. Under this action, a clamping effect can be formed, so that the pipeline can be fixed conveniently. A connecting rod 2 is installed on one side of the pushing mechanism 1. The connecting rod 2 can connect parts. One end of the connecting rod 2 is fixedly connected to a mounting frame 3. The mounting frame 3 is designed as a U-shaped structure. Both sides of the inner cavity of the mounting frame 3 are provided with limiting grooves 4. The inner wall of the limiting groove 4 is provided with a limiting mechanism 5. The limiting mechanism 5 can clamp and fix pipelines of different diameters, and has a large contact area with the pipeline, so that the device has a better positioning effect on the pipeline. A fixing groove 6 is opened on one side of the mounting frame 3. The inner wall of the fixing groove 6 is rotatably connected to a spur gear 7. Rack plates 8 are meshed on both sides of the surface of the spur gear 7. The surface of the rack plate 8 is slidably connected to the inner wall of the fixing groove 6. Under this action, The rack plate 8 can be made more stable when moving, and the rack plate 8 can be prevented from being unstable when moving and affecting the meshing between the spur gears 7. Under the cooperation of the spur gear 7 and the rack plate 8, when the rack plate 8 on one side moves, the rack plate 8 on the other side can move in the same direction or oppositely at the same time. A positioning mechanism 9 is installed on one side of the rack plate 8, and the positioning mechanism 9 can limit the limiting mechanism 5, so that the limiting mechanism 5 will not move easily after rotation, thereby improving the positioning effect of the device on the pipeline, and under the action of the positioning mechanism 9, it is also convenient to replace the limiting mechanism 5, so as to improve the applicability of the device and facilitate the positioning of pipelines with different diameters. A reset mechanism 10 is installed on the surface of the rack plate 8, and the reset mechanism 10 can make the rack plate 8 return to its original position after moving, so as to facilitate the limiting of the limiting mechanism 5, which is not only more convenient, but also improves the limiting effect of the limiting mechanism 5.

[0023] The limiting mechanism 5 includes a slider 51, the surface of the slider 51 is slidably connected to the inner wall of the limiting groove 4, a connecting rod 52 is fixedly connected to one side of the slider 51, and a limiting plate 53 is fixedly connected to the surface of the connecting rod 52. The limiting plate 53 is designed as an arc-shaped structure. There are three limiting plates 53, and they are all distributed in a circular array at the center of the connecting rod 52. The inner diameters of the three limiting plates 53 are all different. Under this effect, a suitable limiting plate 53 can be selected according to the diameter of the pipeline, and the contact area with the pipeline is larger with the cooperation of the shape of the limiting plate 53, thereby improving the positioning effect of the device on the pipeline, and the cooperation between the slider 51 and the limiting groove 4 also facilitates the replacement of the limiting mechanism 5, thereby facilitating the staff to select a suitable limiting plate 53.

[0024] The positioning mechanism 9 includes a connecting plate 91, and there are two connecting plates 91. One side of the connecting plate 91 is fixedly connected to the surface of the rack plate 8. A positioning rod 92 is fixedly connected to one side of the connecting plate 91. There are three positioning rods 92. The other end of the positioning rod 92 penetrates into the inner cavity of the mounting frame 3 and is slidably connected to the inner wall of the penetration point. A positioning groove 93 is provided on the surface of the connecting rod 52. The inner wall of the positioning groove 93 is slidably connected to the surface of the positioning rod 92. Under this action, the connecting rod 52 can be easily limited, so that it will not move easily after selecting a suitable limiting plate 53, thereby facilitating the subsequent positioning of the pipeline.

[0025] The reset mechanism 10 includes a connecting groove 101 opened at the top and bottom of the inner cavity of the fixed groove 6, and a moving plate 102 is slidably connected to the inner cavity of the connecting groove 101. One side of the moving plate 102 is fixedly connected to the surface of the rack plate 8, and one side of the moving plate 102 is fixedly connected to a compression spring 103. The other end of the compression spring 103 is fixedly connected to the inner wall of the connecting groove 101. Under this action, the compression spring 103 can be squeezed by the moving plate 102 when the rack plate 8 is moved, so that it can be compressed. When the compression spring 103 is not squeezed, the moving plate 102 can be moved under its own action. The plate 102 returns to its original position, making it convenient to move the rack plate 8 back to its original position, so as to facilitate the limiting of the limiting mechanism 5. The inner wall of the connecting groove 101 is fixedly connected with a guide rod 11, and the other end of the guide rod 11 penetrates to the other end of the movable plate 102 and is slidably connected to the inner wall of the penetration point. Under this action, the movable plate 102 can be guided, so that it can be more stable when moving. The guide rod 11 is located inside the compression spring 103. Under this action, the compression spring 103 can be guided when it is compressed or rebounded, so that it can be more stable when compressed or rebounded.

[0026] It is worth noting that the technical features such as the propulsion mechanism 1 proposed in this technical solution should be regarded as the technology in the comparative case. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to the conventional methods in the field, and this technical solution will not be further elaborated.

[0027] Working principle: First, the staff pulls the connecting plate 91 to drive the positioning rod 92 to disengage from the inside of the positioning groove 93. With the cooperation of the connecting plate 91, the rack plate 8 will use the spur gear 7 to make the positioning rod 92 on the other side also disengage from the inside of the positioning groove 93. Then, according to the diameter of the pipeline, the connecting rod 52 is rotated to select a suitable limit plate 53. After the selection is completed, the connecting plate 91 is released. Under the action of the compression spring 103, the movable plate 102 can be pushed to move, so that the movable plate 102 drives the connecting plate 91 back to its original position through the rack plate 8, so that the positioning rod 92 is embedded in the inside of the positioning groove 93, the connecting rod 52 is limited, and then the limit plate 53 on the other side is adjusted. After the adjustment is completed, the forward and reverse dual-axis motor inside the pushing mechanism 1 is turned on. Under this action, the two limit plates 53 can clamp and position the pipeline through the rotating rod and the first bevel gear and other structures.
