Description

Technical Field

[0001] This utility model relates to the technical field of cable laying auxiliary equipment, and in particular to a high flame-retardant B1-grade flexible fireproof composite cable laying auxiliary device. Background Technology

[0002] In building electrical engineering, rail transit, and public facility construction, high flame-retardant B1-grade flexible fire-resistant composite cables are widely used in safety-critical scenarios such as fire protection systems and emergency power supply due to their excellent flame retardancy, low smoke and halogen-free properties, and bending flexibility. These cables are typically transported to the construction site in heavy-duty reels, and during laying, they require cable conveyor racks to pull and release the cables from the reels.

[0003] Existing cable conveyor systems commonly employ rubber track linear traction mechanisms. However, rubber tracks can only provide unidirectional linear traction force and cannot adapt to complex paths on construction sites (such as turns). This results in significant manual intervention for secondary bending adjustments and routing corrections after the cable is unwound. When manually adjusting the cable angle, workers must repeatedly drag and twist the cable to meet the laying trajectory requirements, which not only significantly reduces construction efficiency but also easily damages the cable's outer sheath due to excessive bending, affecting the integrity of the B1-grade flame-retardant layer. Consequently, overall construction efficiency is low, impacting project safety and quality. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a high flame retardant B1 grade flexible fireproof composite cable laying auxiliary device. This design effectively solves the problem that the existing cable conveying equipment can only perform linear traction, and manual assistance is still required during cable laying, which affects the construction efficiency and construction quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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.

[0022] Please see the appendix Figure 1-6 This embodiment provides an auxiliary device for laying high flame-retardant B1-grade flexible fireproof composite cables: it includes a base 1, a traction box 2 fixedly connected to the base 1, a rubber track 3 inside the traction box 2, a rubber pressure roller 4 above the rubber track 3, a lifting platform 5 rotatably connected to the rubber pressure roller 4, an adjusting frame 6 hinged to the side of the traction box 2, a lower roller body 7 rotatably connected to the adjusting frame 6, an upper roller body 8 above the lower roller body 7, and the upper roller body 8 rotatably connected to the adjusting frame 6.

[0023] like Figure 1As shown, the base 1 has two layers of horizontally arranged transverse plates. The traction box 2 is located on the upper transverse plate. The upper end of the traction line has a groove. The rubber track 3 is installed on the traction box 2. The lifting platform 5 is located above the traction box 2. The height of the lifting platform 5 relative to the traction box 2 is adjustable. The lower side of the lifting platform 5 also has a groove. There are multiple rubber pressure rollers 4, which are installed side by side on the lifting platform 5. When the cable is being pulled, the cable passes between the lifting platform 5 and the traction box 2. Under the action of the two grooves, the cable is supported by the rubber track 3 below and squeezed downward by the rubber pressure rollers 4 above. Through the squeezing of the rubber pressure rollers 4, the friction between the cable and the rubber track 3 increases. Thus, when the rubber track 3 rotates, the rubber track 3... The rubber track 3 will drive the cable to move to the left. The rubber pressure roller 4 and the lifting platform 5 are rotatably connected to reduce the resistance when the cable moves and prevent the cable sheath from being damaged by friction. After passing through the traction box 2, the cable enters the adjusting frame 6. In the initial state, the uppermost end of the lower roller 7 in the adjusting frame 6 is at the same height as the uppermost end of the rubber track 3, and the lowermost end of the lower roller 7 is at the same height as the lowermost end of the rubber pressure roller 4. The cable passes between the upper roller 8 and the lower roller 7. When it is necessary to change the cable travel angle, the adjusting frame 6 can be adjusted upward. The adjusting frame 6 rotates upward relative to the traction box 2, which can change the inclination angle of the cable movement, so that the device can flexibly adapt to the complex installation environment in actual use.

[0024] Furthermore, such as Figure 4 and Figure 5 As shown, to make the corner of the cable at the adjusting frame 6 smoother and avoid damage to the cable caused by bending, there are three lower rollers 7 on the adjusting frame 6. One lower roller 7 is located at the hinge position between the adjusting frame 6 and the traction box 2. This lower roller 7 remains stationary when the adjusting frame 6 rotates. The other two lower rollers 7 adjust their positions as the adjusting frame 6 rotates. The lower rollers 7 limit the upper end of the cable to prevent the cable from detaching at the adjusting frame 6. Both the upper roller 8 and the lower roller 7 are columnar structures, which can prevent scratches on the outside of the cable. In addition, a drive shaft is installed on the leftmost lower roller 7. The pulley group 10 consists of two pulleys and a connecting belt. One of the two pulleys is fixedly connected to the drive shaft, and the other pulley is connected to the drive wheel 9. The other drive wheel 9 is connected to a drive motor. The operation of the motor drives the rubber track 3 and the drive wheel 9 to rotate. The rotation of the drive wheel 9 drives the lower roller 7 to rotate through the pulley and the connecting belt. The lower roller 7 rotates in the same direction as the rubber track 3, thereby moving the cable to the left.

[0025] The lifting platform 5 can move vertically relative to the traction box 2. The vertical movement of the lifting platform 5 is adjusted by the first screw 13. There are two first guide rods 11, which are located on the left and right sides of the first screw 13 respectively. The two first guide rods 11 guide the movement of the lifting platform 5. The limiting plate 12 limits the upper limit position of the lifting platform 5 to prevent the lifting platform 5 from disengaging from the first guide rods 11. The vertical lifting of the lifting platform 5 can drive the vertical movement of the rubber pressure roller 4, thereby changing the distance between the rubber pressure roller 4 and the rubber track 3, so that the device can be used with cables of different shaft diameters.

[0026] The support block 601 on the adjusting frame 6 has a triangular prism structure, with the upper roller 8 located at the upper end and three lower rollers 7 arranged side by side at the lower end, as shown below. Figure 1 and Figure 4 As shown, the right side of the support block 601 is hinged to the traction box 2, the left side of the support block 601 is hinged to the connecting rod 602, and the lower part of the connecting rod 602 is hinged to the slider 603. When the slider 603 moves to the left, the slider 603 drives the lower end of the connecting rod 602 to move to the left. After the connecting rod 602 moves to the left, the connecting rod 602 drives the support block 601 to rotate upward. The support block 601 drives the upper roller 8 and part of the lower roller 7 to rotate upward, thereby changing the direction of the cable outlet and making the device more suitable for the application scenario.

[0027] The left and right sliding of slider 603 is adjusted by the second screw 606. Both the second screw 606 and the first screw 13 are equipped with handles at their ends, which can be adjusted manually. Slider 603 is located in the slide groove 604 of base 1. The guide rod in the slide groove 604 guides the movement of slider 603.

[0028] The traction box 2 is equipped with a support rod 14 and guide rollers 15 in the cable entry direction. There are two guide rollers 15, both of which are cylindrical structures that are thinner in the middle and thicker at both ends. Before the cable enters the traction line, it needs to pass between the two guide rollers 15. The two guide rollers 15 limit and guide the position of the cable, ensuring that the cable's trajectory moves along the centerline of the rubber track 3. The support rod 14 supports the two guide rollers 15. The guide rollers 15 are installed in the mounting holes 17 on the support rod 14 through the connecting shaft 16. There are multiple mounting holes 17. By cooperating with different mounting holes 17, the distance between the two guide rollers 15 can be adjusted so that the distance between them matches the cable shaft diameter. At the same time, the height of the guide rollers 15 can also be adjusted.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
