The extrusion sleeve driving gear 130 is meshed and slidably matched with the gear column 127.

[0022] The working principle of a ship cable laying and fixing device disclosed in the present invention is as follows: the cable is laid on the surface of the shipboard, and then a cable fixing piece 116 is taken and buckled on the cable. At this time, the device is moved over to allow the stabilizing bracket 101 to contact the surface of the shipboard, and the sliding table 103 is moved to make the drill bit 115 move to the middle of the cable fixing piece 116, and then the first electric cylinder 105 is controlled, and the telescopic rod of the first electric cylinder 105 drives the moving platform 107 to move downward. At this time, the drill bit 115 on the moving platform 107 will also move synchronously, and the first driving motor 111 is started at the same time. The output shaft of the first driving motor 111 drives the drill bit 115 to rotate, and then drives another drill bit 115 to rotate through the first transmission chain 114. At this time, the two drill bits 115 rotate simultaneously. As the telescopic rod of the first electric cylinder 105 moves, the drill bit 115 will contact the cable fixing piece 116, and drill through holes in the cable fixing piece 116 and the shipboard to insert the core-pulling rivet 122. Then, the first drive motor 111 is stopped or reversed and then stopped, and the telescopic rod of the first electric cylinder 105 is controlled to retract, so that the drill bit 115 is pulled out from the drilled through hole.Move the sliding platform 103 to the other end of the guide sliding rod column 102 (the sliding platform 103 and the two stable brackets 101 are magnetically matched, and the stable brackets 101 are magnetically matched with the shipboard). At this time, the blind rivet guide rail 121 is aligned with the through hole drilled by the drill bit 115, and then control the extension of the telescopic rod of the second electric cylinder 118, so that the telescopic rod of the second electric cylinder 118 drives the pull-out plate 125 to move toward the shipboard (at the same time, the pull-out plate bracket 124 is supported on the top fixed plate). The movement of the pull plate 125 will drive the elastic three-claw 128 to move. Before that, the user places a blind rivet 122 (or multiple blind rivets can be placed to facilitate the fixing of the next point of the cable) on each of the two blind rivet guides 121, and slides the blind rivet 122 to the through hole position of the blind rivet guide 121, so that the blind rivet 122 falls into the through hole drilled by the drill bit 115. As the elastic three-claw 128 moves, the blind rivet The nail core of the nail 122 will be inserted into the elastic three-claw 128, and then the second drive motor 131 will be started. The output shaft of the second drive motor 131 will drive the gear column 127 to rotate, and the two gear columns 127 will rotate synchronously through the second transmission chain 126. The rotation of the gear column 127 will drive the extrusion sleeve driving gear 130 to rotate, and the rotation of the extrusion sleeve driving gear 130 will drive the extrusion sleeve 129 to rotate. The extrusion sleeve 129 will rotate on the locking stud 132 and move along the axial direction of the locking stud 132. At this time, the extrusion sleeve 129 will squeeze and narrow the elastic three-claw 128, so that the elastic three-claw 128 squeezes and fixes the nail core of the blind rivet 122, and then controls the telescopic rod of the second electric cylinder 118 to contract. At this time, the nail core of the blind rivet 122 will be pulled out of the rivet body driven by the elastic three-claw 128, and the cable fixing piece 116 will be fixed on the shipboard, thereby fixing the cable on the shipboard (hull). Then, the second driving motor 131 is reversed to reset the extrusion sleeve 129 so that the elastic three claws 128 are unfolded to facilitate the insertion of the nail core of the next blind rivet 122.
