Description

Technical Field

[0001] This utility model relates to the field of building cable technology, specifically a portable building cable laying traction machine. Background Technology

[0002] In modern construction engineering, cable laying is a core link in power transmission and communication network construction, which is directly related to the realization of building functions and the stability of system operation. With the expansion of building scale and the increase in intelligent needs, the requirements for cable specifications, length and laying efficiency are becoming more and more stringent. Cable laying in the vertical shaft of high-rise buildings requires pulling hundreds of meters of large-diameter cables. Traditional manual pulling is not only inefficient, but also poses problems such as cable damage and safety hazards. Therefore, there is an urgent need for efficient and reliable cable laying and pulling equipment to ensure construction quality and progress.

[0003] Currently, most cable laying and pulling equipment on the market is either fixed or large vehicle-mounted. While fixed pulling machines have a large pulling force, they are difficult to adapt to the narrow spaces and complex terrain of construction sites. Installation and dismantling are time-consuming and labor-intensive, failing to meet the needs of flexible scheduling. Large vehicle-mounted pulling machines suffer from poor mobility and high costs, and are difficult to operate indoors or in areas with limited space. In addition, traditional equipment lacks intelligent control of cable tension, which can easily lead to cable sheath damage and internal core breakage due to uneven tension, resulting in material waste and increased rework costs. They can no longer meet the development trend of efficient and refined construction in modern buildings. Therefore, we propose a portable building cable laying and pulling machine.

[0036] Support block 7: Fixed to the right side of traction base 1, with an internal movable cavity 15 and slide rail 16, and a cable rack 8 rotatably mounted on top, providing an angle-adjustable support base;

[0037] Cable rack 8: Rotatably mounted on the top of support block 7, with fixing rings 9 at both ends and fixing parts 11 for positioning, used to place cable reels, and can be adjusted at multiple angles to adapt to wiring needs;

[0038] Fixed ring 9: Located at both ends of the cable frame 8, with limiting holes 17 on the outer cylindrical surface, which are inserted into the fixing rod at the top of the fixing member 11 to realize the positioning and angle locking of the cable frame 8;

[0039] Sliding component 10: The end sliding head 19 cooperates with the sliding groove 20 of the fixing component 11. When pulled, it drives the fixing component 11 to move up and down, unlocking or locking the angle of the cable rack 8.

[0040] Fixing component 11: Installed in the movable cavity 15 of the support block 7, the top fixing rod is inserted into the limiting hole 17 of the fixing ring 9, and the bottom interlocking spring 12 is used to fix the cable rack 8;

[0041] Locking spring 12: Located at the bottom of the fixing member 11, it provides elastic support. When the sliding member 10 is released, it pushes the fixing member 11 to move upward, ensuring that the fixing rod and the limiting hole 17 are tightly fitted.

[0042] Connecting block 13: Located on the top left side of the traction base 1, the internal cross-shaped positioning groove 14 is inserted into the positioning block 18 of the connecting strip 2, and the structural connection strength is enhanced after the bolt is fixed.

[0043] Positioning groove 14: Located inside the connecting block 13, it is cross-shaped and precisely matches the positioning block 18 of the connecting strip 2 to achieve the positioning and installation of the connecting strip 2 and the traction base 1;

[0044] Movable cavity 15: Located inside the support block 7, it accommodates the fixing component 11 and the locking spring 12, providing space for the movement of components when the angle of the cable rack 8 is adjusted;

[0045] Slide rail 16: Located on the front end face of the movable cavity 15 of the support block 7, it is T-shaped and cooperates with the front end of the slider 10 to guide the slider 10 to move and control the lifting and lowering of the fixed part 11;

[0046] Limiting holes 17: distributed in a ring on the outer cylindrical surface of the fixing ring 9, and inserted into the fixing rod at the top of the fixing part 11 to realize the limiting and fixing of the cable rack 8 at different angles;

[0047] Positioning block 18: Located at the end of the connecting strip 2, it is inserted into the positioning groove 14 of the connecting block 13 and fixed with bolts to ensure that the connecting strip 2 is firmly connected to the traction base 1;

[0048] Sliding end 19: Located at the end of the slider 10, it is T-shaped and slides into the sliding groove 20 of the fixing member 11 to transmit operating force to control the movement of the fixing member 11;

[0049] Sliding groove 20: Located on the front end face of the fixed part 11, it is T-shaped and cooperates with the sliding end 19 of the sliding part 10 to guide the movement of the sliding part 10, thereby realizing the lifting control working principle of the fixed part 11. In terms of the basic structure construction of the traction machine, the connecting block 13 on the top left side of the traction base 1 and the connecting strip 2 form a stable connection. The positioning groove 14 in the shape of a cross inside the connecting block 13 is tightly inserted with the positioning block 18 at the end of the connecting strip 2, and then fixed by bolts to ensure the connection strength. The support shaft 3 installed between the two connecting strips 2 provides basic support for subsequent cable traction. The design of the bottom moving wheels makes it possible to... The entire machine can be easily moved on construction sites. During cable pulling, the movable cylinder 4 sleeved on the support shaft 3 plays a crucial role. The movable cylinder 4 can slide freely along the support shaft 3, and the cable threading cylinder 5 at its bottom is used to thread the cable. When the cable is subjected to lateral pulling force, the movable cylinder 4 will slide on the support shaft 3. At this time, the return springs 6 on both sides are compressed, absorbing the tension fluctuations during cable pulling through elastic deformation, making the tension on the cable more stable and effectively avoiding cable damage caused by sudden changes in tension. When pulling is completed or the tension disappears, the return springs 6 release elastic potential energy, pushing the movable cylinder 4 to return to its original position. Before the next traction, the fixing and rotation adjustment of the cable frame 8 are equally important. The support block 7 on the top right of the traction base 1 has a movable cavity 15 inside, where the fixing member 11 and locking spring 12 are installed. The fixing rod at the top of the fixing member 11 can be inserted into the limiting holes 17 of the fixing rings 9 at both ends of the cable frame 8 to achieve positioning and fixing of the cable frame 8. If it is necessary to rotate the cable frame 8, simply pull the sliding member 10 downwards. Its T-shaped sliding end 19 slides within the sliding groove 20 of the fixing member 11, causing the fixing member 11 to move downwards, disengaging the fixing rod from the limiting hole 17. At this point, the cable frame 8 can be rotated to release the tension. When the sliding member 10 is opened, under the elastic force of the locking spring 12, the fixing member 11 moves upward, and the fixing rod is re-inserted into the corresponding limiting hole 17, thus completing the fixing of the cable rack 8. This prevents excess wire ends from being exposed when the cable is not being laid, which would affect the cable's performance. In addition, the push handle on the right side of the traction base 1 allows the operator to control the movement direction and position of the entire machine during the traction process. In conjunction with the moving wheels, it enables flexible scheduling of the traction machine on the construction site. With the cooperation of all components, the cable laying work can be completed efficiently, stably, and flexibly during construction, greatly improving the efficiency and quality of cable laying.
