Description

Technical Field

[0001] The present invention relates to the technical field of optical cable traction machines, and in particular to an optical cable traction machine and a traction method thereof that are resistant to compression and tensile damage. Background Art

[0002] Optical cable is a communication medium used to transmit optical signals, usually composed of optical fibers. It transmits information in the form of light at high speed through the internal optical fibers, and is commonly used in communication systems such as the Internet, telephone and television. Optical cable has the characteristics of high bandwidth, low loss and anti-electromagnetic interference, and is suitable for long-distance data transmission. The optical cable tractor is a device specially used for laying optical cables. It mechanically pulls the optical cable to the predetermined position to ensure that the optical cable can be laid smoothly, which can effectively reduce the burden of manual handling.

[0003] In the prior art, when using an optical cable traction machine, it is usually necessary to place the optical cable between the upper and lower tracks, and manually adjust the height of the upper track by a screw rod so that the optical cable is in good contact with the two tracks, which is convenient for the subsequent traction of the optical cable. However, the manual adjustment method of the screw rod mainly relies on manual experience and judgment, which is prone to inadequate adjustment or over-adjustment. When the upper track is not adjusted properly, the optical cable and the track cannot be in good contact, resulting in poor subsequent traction effect; when the upper track is over-adjusted, it will cause excessive clamping pressure on the optical cable, which will easily cause the surface of the optical cable to be stretched and worn when the optical cable is subsequently pulled, reducing the mechanical protection performance of the optical cable, making the internal optical fiber more susceptible to the external environment, and reducing the use effect and service life of the optical cable.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is used, the power assembly is started to generate power, the transmission drives the first chain to rotate, drives the rotating rod and the two first gears to rotate, drives the two second gears to rotate simultaneously through the second chain, and then the rotating shaft and the traction roller rotate, thereby driving the two traction crawlers to rotate and traction the optical cable. At the same time, the tension sensor can timely sense the change of the optical cable tension and feed back the signal to the PLC controller. When the tension is abnormal, the PLC controller will control the alarm to sound, prompting the staff to adjust the power output of the traction machine to keep the tension of the optical cable within a safe range, and prevent the optical cable from being damaged due to abnormal tension during the traction process.

At this time, the other end of the lower first connecting rod rotates upward, and the other end of the upper first connecting rod rotates downward, driving the two adjustment plates and the two limit plates to move relative to each other, so that the two traction crawlers move relative to each other and gradually contact the optical cable. When the upper traction crawler contacts the optical cable, the pressure is transmitted to the pressure plate, and then the pressure sensor is pressed by the rubber pressure rod.

At this time, the two traction crawlers and the optical cable maintain a suitable clamping force and good contact. Under the action of the adjustment component, the effect of automatically adjusting the crawler is achieved, preventing the crawler from being over-adjusted and causing greater pressure on the optical cable, and effectively preventing the optical cable from being pulled and worn due to excessive pressure during the subsequent traction process.

[0018] 3. When the present invention is used, the arc-shaped elastic strip can increase the friction between the optical cable and the traction track, provide better traction, and can also buffer the pressure on the optical cable to a certain extent.

[0025] In this embodiment, when in use, the forward and reverse motor 311 is started, and the rotating block 312 is driven to rotate slowly through the output end of the forward and reverse motor 311, and the corresponding arc block 309 and the adjusting gear ring 310 are driven to rotate through the connected fixed rod 313, and the first connecting rod 307 below is further driven to rotate on the outer surface of the first limiting rod 306 below. The second limiting rod 308 is movably connected to the first connecting rod 307. When one end of the first connecting rod 307 is limited by the first limiting rod 306, the other end thereof will rotate upward, and the lower adjustment plate 303 is driven to move upward in the lower movable hole 302 through the second limiting rod 308.

When the lower adjusting toothed ring 310 rotates, it will drive the upper adjusting toothed ring 310 to rotate together, further driving the upper first connecting rod 307 to rotate on the outer surface of the upper first limiting rod 306, and the other end of the upper first connecting rod 307 rotates downward, and the upper adjusting plate 303 is driven to move downward in the upper movable hole 302 through the movable second limiting rod 308, thereby driving the two limiting plates 304 to move relative to each other, thereby pushing the bottom of the upper traction crawler 209 downward and the top of the lower traction crawler 209 upward, so that the two traction crawlers 209 gradually contact with the optical cable. When the upper adjustment plate 303 moves, the detection plate 316 and the pressure plate 319 will move downward together.

When the pressure data exceeds the set pressure threshold, the PLC controller 4 will control the forward and reverse motors 311 to turn off, and the two The limit plate 304 stops moving. At this time, the two traction tracks 209 maintain appropriate clamping force and good contact with the optical cable. Under the action of the adjustment component 3, the track is automatically adjusted to prevent excessive adjustment of the track, which will cause greater pressure on the optical cable. It effectively prevents the optical cable from being strained and worn due to excessive pressure during the subsequent traction process. It solves the problem that when the optical cable traction machine is in use, the upper track is manually adjusted by the screw. If the adjustment is not in place, the subsequent traction effect will be poor. If the adjustment is excessive, the clamping pressure on the optical cable will be too high, which will easily cause the surface of the optical cable to be strained and worn during the traction process, reduce the mechanical protection performance of the optical cable, and affect the use effect of the optical cable. During the traction process, the optical cable can be effectively positioned by the four positioning plates 305 around it to prevent position displacement during the traction process and affect the traction effect.

[0026] The traction method and working principle of the present invention are as follows: the optical cable is passed through the tension sensor 5, the two traction wheels 9 on the left, the two traction crawlers 209 and the two traction wheels 9 on the right in sequence, the forward and reverse motors 311 are started, the rotating block 312 is driven to rotate slowly, and the corresponding arc block 309 and the adjusting tooth ring 310 are driven to rotate through the fixed rod 313, and the other adjusting tooth ring 310 is driven to rotate together, and the two first connecting rods 307 are respectively rotated on the outer surfaces of the two first limiting rods 306, and the other end of the lower first connecting rod 307 is rotated upward, and the other end of the upper first connecting rod 307 is rotated downward, so that the two adjustment plates 303 and the two limiting plates 304 are driven to move relative to each other through the second limiting rod 308, the bottom of the upper traction crawler 209 is pushed downward, and the top of the lower traction crawler 209 is pushed upward, so that the two traction crawlers 209 gradually contact with the optical cable. When the upper adjustment plate 303 moves, it will drive the detection plate 316 and the pressure plate 319 to move downward together. When the bottom of the upper traction track 209 contacts the optical cable, a relative force will be generated on the traction track 209 and transmitted to the pressure plate 319. The pressure plate 319 moves upward under the thrust, causing the support rod 318 and the rubber pressure rod 322 to move upward at the same time. The rubber pressure rod 322 generates pressure on the pressure sensor 317. At the same time, the pressure sensor 317 will transmit the detected pressure signal to the PLC controller 4 for identification and comparison. When the pressure data exceeds the set pressure threshold, the PLC controller 4 will control the forward and reverse motors 311 to turn off, and the two limit plates 304 will stop moving. At this time, the two traction tracks 209 maintain a suitable clamping force with the optical cable for good contact. The power assembly 202 is started to generate power, and the first chain 204 is driven to rotate through the connecting gear at the output end of the transmission 203, and the rotating rod 205 and the two first gears 206 are driven to rotate, and the two second gears 208 are driven to rotate simultaneously through the second chain 207, and then the two corresponding rotating shafts 212 and the traction roller 211 are driven to rotate, thereby driving the two traction crawlers 209 to rotate, generating traction on the optical cable, and at the same time, the tension sensor 5 can timely sense the change of the optical cable tension, and feed back the signal to the PLC controller 4, and the PLC controller 4 controls its internal alarm according to the feedback signal. When the tension is abnormal, the PLC controller 4 will control the alarm to sound, prompting the staff to adjust the power output of the traction machine to keep the tension of the optical cable within a safe range.
