Description

Technical Field

[0001] This utility model relates to the field of pipeline laying technology, specifically a pipeline laying guide device for old urban area renovation. Background Technology

[0002] During the renovation of old urban areas, it is often necessary to re-lay new cables, optical cables, water pipes and other pipelines in existing pipe wells, wall holes or underground pre-buried pipes with extremely limited space. These existing channels often have problems such as narrow space, irregular hole walls and inconsistent inner diameters.

[0003] Currently, the common construction method involves pulling the pipeline at its end and manually guiding it at the entrance. This method has significant drawbacks: First, manual operation is extremely inconvenient and inefficient in narrow spaces. Second, due to the lack of effective centering guidance, the pipeline is prone to severe friction with rough or irregular hole walls during installation, resulting in scratches and wear on the pipeline's outer sheath, seriously affecting its service life and even causing direct damage. Finally, existing pipeline installation guidance devices cannot accurately guide the pipeline according to its inner diameter.

[0004] Therefore, those skilled in the art have provided a pipeline laying guide device for old city renovation to solve the problems mentioned in the background art. Utility Model Content

[0008] As a further improvement of this utility model: each telescopic rod has a protective pad fixedly connected to its telescopic end, and the outer surface of each protective pad is in contact with the outer surface of the wire.

[0009] As a further improvement of this utility model: a stabilizing plate is fixedly connected to the outer surface of each drive motor, and the outer surface of each stabilizing plate is fixedly connected to the outer surface of the connecting plate.

[0010] As a further improvement of this utility model: each of the servo motors has an L-shaped plate fixedly connected to its outer surface, and the outer surface of each L-shaped plate is fixedly connected to the outer surface of the fixed cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Please see Figure 1-6A pipeline laying guide device for old city renovation includes a conductor 1, with a clamping and guiding adjustment mechanism 2 installed on the outside of the conductor 1. The clamping and guiding adjustment mechanism 2 includes a protective cylinder 201, with the outer surface of the conductor 1 nested inside the protective cylinder 201. Two sets of telescopic rods 209 are fixedly connected to the inner wall of the protective cylinder 201. A controller body 210 and a battery body 211 are fixedly connected to the outer surface of the protective cylinder 201, and a fixed cylinder 202 is fixedly connected to the outer surface of the protective cylinder 201. Several identical movable plates 204 are movably hinged to the outer surface of the protective cylinder 201, and three servo motors 2 are installed on the outside of the fixed cylinder 202. 08. The power output end of each servo motor 208 is rotatably connected to the inner wall of the fixed cylinder 202. The outer surface of the power output end of each servo motor 208 is fixedly connected to a support plate 203. The outer surface of each support plate 203 is movably hinged to the inner wall of one of the movable plates 204. The inner walls of each set of movable plates 204 are movably hinged to a connecting plate 205. Two drive motors 206 are provided on the outer side of each connecting plate 205. The outer surface of the power output end of each drive motor 206 is rotatably connected to the inner wall of the connecting plate 205. The power output end of each drive motor 206 is fixedly connected to a roller 207.

[0029] Example 2

[0030] Please see Figure 1-6 Each telescopic rod 209 has a protective pad 6 fixedly connected to its telescopic end. The outer surface of each protective pad 6 is in contact with the outer surface of the wire 1. The protective pad 6 is made of high friction coefficient rubber material to increase the friction with the wire 1, prevent the device from slipping when moving in the pipeline, and avoid scratching the surface of the wire 1.

[0031] Each drive motor 206 has a stabilizing plate 3 fixedly connected to its outer surface. The outer surface of each stabilizing plate 3 is fixedly connected to the outer surface of the connecting plate 205. The stabilizing plate 3 is used to enhance the connection rigidity between the drive motor 206 and the connecting plate 205, suppress the vibration of the drive motor 206 during operation, and ensure the stability of the transmission.

[0032] Each servo motor 208 has an L-shaped plate 4 fixedly connected to its outer surface. The outer surface of each L-shaped plate 4 is fixedly connected to the outer surface of the fixed cylinder 202. The L-shaped plate 4 provides a stable mounting base for the servo motor 208, ensuring the stability of the servo motor 208 when outputting torque, thereby improving the accuracy of radial adjustment.

[0033] A protective shell 5 is fixedly connected to the outer surface of the controller body 210. The outer surface of the protective shell 5 is fixedly connected to the outer surface of the protective cylinder 201. The protective shell 5 is used for dustproof, waterproof and physical impact protection, protecting the controller body 210 from the harsh environment of the construction site.

[0034] Each telescopic rod 209 has a protective ring 7 fixedly connected to its outer surface. The outer surface of each protective ring 7 is fixedly connected to the inner wall of the protective cylinder 201.

[0035] Example 3

[0036] The working principle of this utility model is as follows: When in use, first pass the wire 1 through the protective cylinder 201, start the device, the battery body 211 supplies power to the entire system, the controller body 210 controls the two sets of telescopic rods 209 to extend, and tightly hold the wire 1 through the protective pads 6 at their ends, thus completing the fixation of the device. The wire 1 is in the center position. Subsequently, the controller body 210 controls the three servo motors 208 to work synchronously according to the preset program or real-time command. The output shaft of the servo motor 208 drives the support plate 203 to rotate, and then through the linkage mechanism composed of the movable plate 204 and the connecting plate 205, the motion is transmitted to the end roller 207, so that it extends radially until it makes good contact with the inner wall of the pipe. The three points are evenly supported, so the automatic centering of the device can be realized. According to the different pipe diameters, the rotation angle of the servo motor 208 is controlled, which indirectly controls the rotation position of the linkage mechanism. Thus, the motion is transmitted to the end roller 207 through the linkage mechanism to achieve contact support on the inner wall of the pipe.

[0037] When laying a new pipeline, the controller starts the drive motor 206, and the motor output shaft directly drives the roller 207 to rotate. Multiple rollers 207 provide forward traction force through friction with the outer wall of the new pipeline, and the auxiliary traction equipment smoothly and steadily sends the pipeline into the depth of the pipeline. The whole process realizes efficient and non-destructive laying in complex pipeline environments through the self-adaptation of the mechanical structure and the active drive of the motor.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
