Description

Technical Field

[0001] This utility model belongs to the field of optical cable laying technology, and in particular relates to a tightening device for laying long optical cables. Background Technology

[0002] For engineering projects such as pipelines, tunnels and bridges, sensing optical cables can be laid for monitoring. Due to the excessive length of the cable, and the fact that expansion bolts are now basically used for Z-shaped bracket installation, the optical cable is laid by clamping the Z-shaped bracket. The distance between two adjacent Z-shaped brackets is designed to be approximately one meter.

[0003] Since the Z-type bracket clamps the optical cable by snapping, if the optical cable is too long during the laying process, both ends of the optical cable at the bracket snapping point will be affected by external forces, which may cause relative slippage. Therefore, it affects the stability of the optical cable fastening and the laying effect. Summary of the Invention

[0004] The purpose of this utility model is to provide a tightening device for laying long optical cables. By designing a new tightening device, a long slide table is installed on the laying vehicle and can move with the laying vehicle. At the same time, through the design of the sliding front clamping cable car and the rear clamping cable car, the position of the optical cable can be tightened on the front side of the support and the clamping cable of the front and rear clamping cable cars can be replaced during the laying process. The optical cable can be tightened in sections during the laying process, and the optical cable is always in a certain taut state, which improves the stability between the support and the optical cable.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0028] Please see Figure 1-2 As shown, this utility model is a tightening device for laying long optical cables, including a laying vehicle connecting platform 1, a long slide 2, a front clamping cable car 3 and a rear clamping cable car 4.

[0029] A cable guide wheel set 5 is fixed at the top of one end of the laying vehicle connecting platform 1. A long slide 2 is fixed at the top of the laying vehicle connecting platform 1. A set of slide rails 201 is provided on the bottom surface of the long slide 2. A set of lead screws 202 is rotatably connected inside the long slide 2.

[0030] The front clamp cable car 3 includes a base 301. The bottom of the base 301 is slidably connected to the slide rail 201 via a slider. The base 301 is provided with a connecting seat 302. The connecting seat 302 is provided with a threaded opening 303 and a clearance opening 304.

[0031] A U-shaped seat plate 305 is fixed to the top of the base 301 by a connecting beam. Cable clamping cylinders 306 are fixed to the inner sides of both sides of the U-shaped seat plate 305. The telescopic ends of the two cable clamping cylinders 306 are arranged opposite to each other and are both fixed with arc-shaped clamping seats 307.

[0032] The structural features of the rear clamp cable car 4 are the same as those of the front clamp cable car 3. The threaded openings 303 on the front clamp cable car 3 and the rear clamp cable car 4 are threadedly connected to the two lead screws 202 respectively. The clearance openings 304 on the front clamp cable car 3 and the rear clamp cable car 4 are respectively fitted outside the two lead screws 202 and do not interfere with each other.

[0033] Among them, such as Figure 1-2 As shown, the arc-shaped clamp 307 is a long strip structure parallel to the slide rail 201. The arc-shaped clamp 307 has an arc-shaped opening on the inner side and a protective pad on the inner wall.

[0034] Among them, such as Figure 1-2 As shown, a bottom support pad 308 is fixed to the inner bottom surface of the U-shaped seat plate 305, and an arc-shaped clamp 307 slides along the upper surface of the bottom support pad 308.

[0035] Among them, a cable clamping groove is formed between the bottom support pad 308 and the two arc-shaped clamps 307 above, and the cable guide opening of the cable guide wheel group 5 is arranged opposite to the cable clamping groove.

[0036] Among them, such as Figure 1-2 As shown, a set of guide posts 309 are fixed on the outside of the arc-shaped clamp 307. The guide posts 309 pass through the side of the U-shaped seat plate 305 and are slidably connected to the side.

[0037] Among them, the end of the laying vehicle connecting platform 1 away from the cable guide wheel group 5 is provided with two driving components, and the two driving components are respectively connected to two lead screws 202.

[0039] The working principle of this utility model is as follows:

[0040] like Figure 3 As shown, at this time, both the front clamping cable car 3 and the rear clamping cable car 4 are in the clamping state. The bracket 6 is installed, and the optical cable 7 is secured to the bracket 6. After the bracket 6 is installed at its designated position, the clamping of the front clamping cable car 3 is released, and a lead screw 202 is driven to move the front clamping cable car 3 towards the rear clamping cable car 4 until it reaches the desired position. Figure 4 At the position shown, the cable is clamped by the front clamping cable car 3, and the cable clamping of the rear clamping cable car 4 is released. The optical cable laying vehicle travels a certain distance, causing the laying vehicle connecting platform 1 and the long slide platform 2 to move in the laying direction. During the movement, the front clamping cable car 3 is driven to move along the long slide platform 2 in the opposite direction to the laying direction, causing the front clamping cable car 3 to be in a relatively stationary state. The final state is as shown. Figure 5 As shown, a new support 6 can be installed near the rear cable car 4 at this time.
