Technical Field

[0001] This utility model relates to the field of cable construction technology, specifically to a cable laying guide and positioning auxiliary tool. Background Technology

[0002] Traditional cable laying relies on manual experience to determine the route, which can easily lead to the following problems in non-visual environments (such as ducts, underground, or concealed spaces):

[0003] 1. Inaccurate positioning causes the cable to deviate from the preset path, requiring manual intervention during laying to ensure accurate cable delivery.

[0004] 2. Lack of real-time feedback, requiring repeated adjustments, resulting in low efficiency;

[0005] 3. Complex terrain (such as curves and environments with many obstacles) makes construction difficult.

[0006] In existing technologies, laser rangefinders or inertial navigation devices are costly and complex to operate, making them unsuitable for small and medium-sized projects. Therefore, there is an urgent need for a specialized tool that is simple in structure, low in cost, and capable of real-time guidance and positioning. Utility Model Content

[0007] The purpose of this utility model is to provide a cable laying guidance and positioning auxiliary tool to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a cable laying guide and positioning auxiliary tool, comprising a guide mechanism, a positioning mechanism, and a support and adjustment mechanism. The guide mechanism includes two sets of symmetrically arranged fixed pulleys, a set of movable pulleys, and a rolling wheel.

The first sleeve is installed inside the second sleeve, and a telescopic structure is formed between them. The two sets of sleeves are limited and fixed by a pin that is inserted into the pin hole.

[0010] Preferably, the upper part of the first sleeve is fixedly connected to the base plate, and the bottom part of the second sleeve is fixedly connected to the base plate.

[0011] Preferably, the frame on the fixed pulley is fixedly mounted on the surface of the substrate via a fixed shaft, and the rolling wheel is mounted on the surface of the substrate via brackets provided on both sides.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a cable laying guide and positioning auxiliary tool, including a guiding mechanism, a positioning mechanism, and a support and adjustment mechanism. The guiding mechanism includes two sets of symmetrically arranged fixed pulleys 1, a set of movable pulleys 2, and a rolling wheel 3. The fixed pulleys 1 are movably mounted on a frame 4, and a cable 5 is arranged between the two sets of fixed pulleys 1. The movable pulley 2 is arranged on the upper left of the fixed pulleys 1, and the movable pulley 2 is movably mounted on a frame 6. The rolling wheel 3 is arranged on the lower left of the movable pulley 2. The movable pulley 2 not only guides the passing cable 5, but also has a positioning function. When the cable 5 passes, the two sets of fixed pulleys 1 provide initial position guidance, while the movable pulley 2 is attached to the upper part of the cable 5. At the same time, the rolling wheel 3 on the side provides further support and guidance. When the cable 5 passes through the three sets of pulleys, it can be effectively guided to prevent deviation, thereby achieving high efficiency during laying.

[0028] Furthermore, the positioning mechanism includes a cylinder 7, a guide shaft 8, a spring 9, a positioning plate 10, and a sensor 11. The cylinder 7 is fixedly mounted on the movable plate 12, and guide shafts 8 are fixedly provided at both ends of the movable plate 12. The other end of the guide shaft 8 is fixedly connected to the positioning plate 10. The frame 6 for mounting the movable pulley 2 is fixedly connected to the positioning plate 10 by bolts 13. The operation of the cylinder 7 enables the positioning plate 10 at the bottom to be height adjusted, thereby making the movable pulley 2 fit tightly against the cable 5 for positioning.

[0029] Specifically, the support adjustment mechanism consists of sleeve one 14 and sleeve two 15. Both sleeve one 14 and sleeve two 15 have pin holes 16 on their surfaces. Sleeve one 14 is installed inside sleeve two 15 and forms a telescopic structure between them. The two sets of sleeves are limited and fixed by a pin shaft 17 that is inserted into the pin hole 16.

[0030] Specifically, the upper part of sleeve 14 is fixedly connected to the base plate 18, and the bottom part of sleeve 2 15 is fixedly connected to the base plate 19.

[0031] As a preferred solution, the support adjustment mechanism changes the support height by adjusting the position of sleeve 14 on sleeve 2 15, and completes the fixed state by inserting pin 17 into pin hole 16. It can adapt to the support height requirements of different scenarios and has flexibility.

[0032] Specifically, the frame 4 on the fixed pulley 1 is fixedly mounted on the surface of the base plate 18 via the fixed shaft 20, and the rolling wheel 3 is mounted on the surface of the base plate 18 via the brackets 21 provided on both sides.

[0033] Specifically, the telescopic rod 22 on the cylinder 7 is fixedly connected to the top plate 23, and the top plate 23 is fixedly mounted on the base plate 18 by the support frame 27.

[0034] Specifically, the guide shaft 8 passes through the top plate 23, and a spring 9 is provided below the top plate 23. The spring 9 is sleeved on the guide shaft 8 and is positioned above the positioning plate 10.

[0035] As a preferred solution, when the cylinder 7 drives the telescopic rod 22 to work, the guide shaft 8 drives the bottom positioning plate 10 to adjust, thereby driving the movable pulley 2 to perform guiding and positioning. The function of the spring 9 is to provide a buffer function and increase protection.

[0036] Specifically, a limiting cylinder 1 24 is fixedly installed on the bottom surface of the top plate 23, and a limiting cylinder 25 is fixedly installed on the surface of the positioning plate 10. The spring 9 is limited and installed between the limiting cylinder 1 24 and the limiting cylinder 25. The purpose of the two sets of limiting cylinders is to limit the position of the spring 9.

[0037] Specifically, sensor 11 is positioned above cable 5 and is fixedly mounted on frame 3 26. Frame 3 26 is fixedly mounted on the side of top plate 23. The purpose of sensor 11 is to sense the passage of cable 5, thereby activating the positioning mechanism, providing real-time feedback, and improving efficiency.

[0038] In specific implementation of this utility model: the cable 5 is passed between two sets of fixed pulleys 1 and attached to the surface of the rolling wheel 3 on one side to form a supporting and guiding function. When the sensor 11 detects that the cable 5 has passed through, the cylinder 7 operates, causing the telescopic rod 22 to retract. During this process, the top plate 23 on the cylinder 7 moves down, and the guide shaft 8 drives the positioning plate 10 to move down simultaneously, so that the movable pulley 2 on the fixedly connected frame 2 is tightly attached to the cable 5, forming a guiding and positioning effect, thereby preventing the cable 5 from deviating or loosening.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
