Description
Technical Field
[0001] The utility model relates to the technical field of high-voltage resistant optical cables, in particular to a cutting device for high-voltage resistant optical cables. Background Art
[0002] High-voltage resistant optical cables are one of the special optical cables for power transmission. They are mainly attached to transmission line towers. The electrical and mechanical properties of the cables meet the requirements of transmission line installation or laying on the same pole. The diameter of the optical cables ranges from 9 cm to 25 cm according to different specifications.
[0003] At present, in the process of laying optical cables, according to the demand for long tubes of optical cables, it is often necessary to cut high-voltage optical cables. Usually, the length of optical cables is measured with a tape measure, and they are cut after measuring the appropriate length. However, this method has certain disadvantages. For example, in most cases, the optical cable needs to be cut into a length of more than ten meters or even dozens of meters. In this case, it can only be measured in multiple sections. First, a certain length of the optical cable is pulled out and measured with a tape measure. After measuring a certain length, it is marked, and then the next section is measured from the marked position. This method has certain disadvantages. For example, during the measurement process, the optical cable cannot be guaranteed to be in a straight state. Once the optical cable bends during the measurement process, the length of the cut optical cable will deviate. At the same time, in the process of resetting the measurement starting point multiple times, whether the mark and the starting point of the tape measure can be kept in the same position is also a key factor affecting the error size. Under the influence of human and on-site environment, the measurement error will gradually increase.

[0029] The working principle of the cutting device for high-voltage resistant optical cables provided by the utility model is as follows:
[0030] When it is necessary to cut the high-voltage resistant optical cable, the staff can first place the device on the flat ground, then put one end of the optical cable on the second pulley group 22, and place it into the placement groove 101 after passing through the second pulley group 22. At this time, the two first pulley groups 18 are located above the optical cable, and under the effect of the two springs 1 21, the optical cable is pressed into the placement groove 101. At the same time, under the effect of the spring 23, the second pulley group 22 lifts the optical cable, so that the optical cable between the second mounting frame 5 and the corresponding first mounting frame 4 is in a straight state. At the same time, under the effect of the two second pulley groups 22, the optical cable located in the placement groove 101 will no longer bend after being straightened by the staff.
[0031] Then the end point of the optical cable can be placed in the clamping frame 9, and the knob can be turned at the same time. The rotation of the knob will drive the adjusting rod 11 to rotate, thereby driving the clamping plate 10 to move downward, and finally clamping and fixing the end point of the optical cable. At this time, the staff can hold the handle on the fixing plate 8 and pull it horizontally. The fixing plate 8 is forced to move horizontally, which will drive the clamping frame 9 and the two sliding rods 7 to move horizontally, thereby stretching the optical cable. The maximum extension distance of the two sliding rods 7 is whole meters. Therefore, after pulling the fixing plate 8 to the farthest distance, the knob can be rotated in the opposite direction to move the clamping plate 10 upward, and then the clamping frame 9 is pulled back to the initial position, and the knob is rotated again to clamp the optical cable at that position. After being fixed, the clamping frame 9 can be stretched again. After being repeatedly pulled to a suitable number of times, the final cutting position is determined in conjunction with the position of the cutting groove 3 on the scale 2, and then the two threaded cylinders 15 can be rotated respectively. The rotation of the two threaded cylinders 15 will cause the two plugs 14 to contact the two friction pads 13 respectively, thereby positioning the clamping frame 9 to prevent accidental pulling and the occurrence of cutting position deviation. The two screw rods 19 are rotated respectively. The rotation of the screw rods 19 will drive the two contact heads 20 to move downward, and finally contact the two first pulley groups 18, so that the two first pulley groups 18 move downward and clamp the optical cable to prevent the optical cable from shrinking and bending during the cutting process.
[0032] Compared with the related art, the cutting device for high-voltage resistant optical cable provided by the utility model has the following beneficial effects:
[0033] The utility model provides a cutting device for high-voltage resistant optical cables. During the cutting operation of the optical cables, the required number of meters of the optical cables can be quickly determined, and the part that does not reach the whole number of meters can be accurately marked by the scale 2. In the cutting process, the clamping frame 9 is fixed to prevent accidental pulling and the cutting position from being offset. At the same time, the two ends of the optical cable can be fixed during cutting to avoid the shrinkage and bending of the optical cable during the cutting process. The whole process is not only simple and convenient, but also simple to operate, and is convenient to use in various complex environments, which improves the accuracy of optical cable cutting to a certain extent.
