Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, and in particular to an anti-wear structure for cable laying. Background Art

[0002] In the construction of power transmission engineering cables, it is necessary to lay the cables in underground pipelines or constructed cable trenches. When laying, first put the traction rope from a cable well, and after the traction rope reaches the next cable well or directly connects to the power facilities, retract the traction rope at the target location so that the cable follows the traction rope to the target location.

[0003] However, when laying cables in the cable trench, the cable trench corners will be encountered. During the laying process, the cables will inevitably rub against the corners and cable well walls due to changes in direction and bending. However, due to the large pulling force required for laying the cables, the cables are also subjected to severe friction. In addition, the cable trench corners have relatively sharp edges, which often leave some obvious scratches on the cables. Occasionally, these scratches contain cracks. These cracks do not cause any abnormalities when the cables are first installed and used, but after a period of use, they can easily cause the cables to break, resulting in short circuits and grounding, burning the cables, causing safety accidents, and posing a safety hazard.

[0004] Moreover, after the existing cables are laid, it is impossible to monitor and determine the status of the cables. Once the cables are accidentally pulled, no timely warning can be given. The only way to discover the problem is when the inspection personnel conduct inspections at the prescribed time. This is not effective, and there is a risk of the cables being pulled and breaking the skin, causing a short circuit and grounding, and burning the cables. Utility Model Content

[0039] In the disclosed embodiment, a microcontroller 1013 and a battery 1010 and a 5G module 1011 electrically connected thereto are provided inside the right mounting block 1; the 5G module 1011 is connected to a mobile device 1012 for wireless network transmission, and the mobile device 1012 is a mobile phone of a cable inspector. Therefore, when it is monitored that the cable is pulled, a message can be sent to the mobile device 1012 which is a mobile phone of the cable inspector through the 5G module 1011, so that the inspector can be informed in time; the battery 1010 is an external power source; the displacement monitoring switch 304 is electrically connected to the microcontroller 1013; a group of buzzers 303 are fixedly installed on the top surface of the reciprocating moving block 3, and the buzzer 303 is electrically connected to the microcontroller 1013.

[0040] Embodiment 2, based on embodiment 1, a wear-resistant matching block 103 is fixedly mounted at the middle of the front end surface of the right mounting block 1 and the left mounting block 101, the front end surface of the wear-resistant matching block 103 adopts a curved surface structure, and in a side view, the edge contour of the wear-resistant matching block 103 coincides with the edge contour of the guide groove 201 of the guide roller 2;

[0041] By setting the anti-wear matching block 103, the guide roller 2 can be cooperated to provide auxiliary support for the cable, and the support of the anti-wear matching block 103 can prevent the cable from contacting the edge corners of the right mounting block 1 and the left mounting block 101, so as to avoid contact wear on the cable.

[0042] The working principle of this embodiment:

[0043] During installation, the right side mounting block 1 and the left side mounting block 101 are buckled at the corner of the cable trench at a 90-degree angle, and the bolt fasteners are inserted through the countersunk through holes 104 and fixedly connected to the wall of the cable trench to achieve the fixed installation of the utility model;

[0044] When the cable is laid to the corner of the cable trench, the cable is placed on the guide groove 201 of the guide roller 2, and the guide roller 2 guides the cable in a direction-changing manner, so that the cable does not contact the corner of the cable trench to avoid damage to the cable.

[0045] When laying the cable, the locking bolt 301 and the threaded blind hole 109 are in a threaded separation state, at which time the reset spring 305 is in an extended state, and the button end of the displacement monitoring switch 304 is higher than the top surface of the driving matching block 202, thereby ensuring that when the cable is laid, the cable movement drives the guide roller 2 to rotate along the rotating seat 105 through the cooperation of the rotating shaft 204 and the bearing 106, and the driving matching block 202 and the rubber pressing strip 203 that rotate synchronously with it will not press against the button end of the displacement monitoring switch 304, so as to avoid the occurrence of false alarms;

[0046] When the cable is laid, the staff can rotate the guide roller 2 to rotate the matching notch a206 to face the key end of the displacement monitoring switch 304, and then press the reciprocating block 3 downward along the notch 107 to compress the reset spring 305. When the reciprocating block 3 moves downward along the notch 107, the matching notch a206 and the matching notch b207 correspond to the position of the key end of the displacement monitoring switch 304. Therefore, when the reciprocating block 3 moves downward along the notch 107, the key end of the displacement monitoring switch 304 will not contact the driving matching block 202, and will not cause any obstruction to the downward movement.

[0047] When the reciprocating block 3 moves downward along the notch 107 until the bottom end surface of the reciprocating block 3 contacts the bottom surface of the inner end of the notch 107, the locking bolt 301 can be tightened along the threaded blind hole 109 by a tool to achieve fixed limit of the reciprocating block 3, and the button end of the displacement monitoring switch 304 is located in the matching notch b207 of the rubber pressure strip 203;

[0048] When the laid cable is accidentally pulled, the pulling of the cable will drive the guide roller 2 to rotate, and when the guide roller 2 rotates, it will synchronously drive the driving matching block 202 to rotate. At this time, driven by the rotation of the driving matching block 202, the matching groove b207 is separated from the button end of the displacement monitoring switch 304, and the rubber pressing strip 203 will press the button end of the displacement monitoring switch 304. At this time, the displacement monitoring switch 304 will be in a pressed start state, and the displacement monitoring switch 304 will give a feedback signal to the microcontroller 1013, and the microcontroller 1013 will control the 5G module 1011 to send a signal to the mobile phone of the inspection personnel. The mobile device 1012 sends a message to remind the inspectors so that they can know and go for inspection in time to observe whether the cable is pulled and damaged. If damaged, they can repair it as soon as possible. Further, when the microcontroller 1013 controls the 5G module 1011 to send a message to the mobile device 1012 which is the inspectors' mobile phone, it also controls the buzzer 303 to start a buzzing sound. The buzzing warning can help mark the location, so that when the inspectors know the message and go for inspection, they can find the correct location in time through the buzzing warning, so as to inspect the cables along the location.
