Description

Technical Field

[0001] The utility model relates to the technical field of transportation cable laying, in particular to a cable laying device for urban rail transportation. Background Art

[0002] In the urban rail transit network, in order to ensure the rapid exchange of information, a large number of powered cables will be laid. These cables can be used to connect various departments to form an invisible online communication platform. Through the coordination between departments, the safety and smoothness of transportation can be guaranteed, and traffic accidents, traffic jams and other adverse situations can be reduced.

[0003] At present, the common cable laying method is generally to place the pay-off roller wrapped with the cable at a specified position, and then lay the cable by pulling the cable end. During this laying method, it was found that every time a line was laid and the cable was cut, the remaining cable on the pay-off roller might be pulled out due to the rotation of the pay-off roller, causing the end of the cable to drag on the ground, causing wear on the cable. In addition, the cable might become loose and tangled when being pulled out, causing more trouble for the subsequent cable laying.

[0004] Therefore, it is necessary to provide a new urban rail transit cable laying equipment to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1-Figure 7 The urban rail transit cable laying equipment comprises: a base 1 and a concave seat 2 arranged above the base 1, a pay-off roller 3 is arranged in the concave seat 2, a cable has been wound on the pay-off roller 3 in the early stage of laying, and a column 1 and a column 2 are fixedly installed on the top of the base 1, wherein a mounting frame 4 is fixedly installed on the top of the column 1, and a guide wheel 5 is rotatably installed in the mounting frame 4, a back plate is fixedly installed on the top of the back plate, a top beam 6 is fixedly installed on the top of the back plate, and a mounting frame 2 7 is fixedly installed on the bottom of the top beam 6 A guide wheel 2 8 is rotatably installed in it, and the guide wheel 2 8 is located above the guide wheel 1 5, and a shaped frame 9 is provided between the mounting frame 1 4 and the mounting frame 2 7, and the top of the arranged column 2 is fixedly connected to the shaped frame 9, and a bidirectional lead screw 10 is rotatably installed in the shaped frame 9, on which two connecting pieces 11 are threadedly installed, and a clamping strip 12 is fixedly installed on one side of the two connecting pieces 11 close to each other. During the laying process, the cable passes between the two clamping strips 12. When the cable is cut, the bidirectional lead screw 10 is rotated. The cable is clamped by two clamping strips 12 in the manner of a lead screw 10, and a rotating shaft 13 is rotatably installed on both sides of the concave seat 1 2, and slots 14 are provided on the two rotating shafts 13, and plug boards 15 are inserted in the two slots 14. The two plug boards 15 are fixedly connected to the pay-off roller 3 on the sides close to each other, and a concave seat 2 16 is fixedly installed at the bottom of the concave seat 1 2, and the bottom of the concave seat 2 16 is fixedly connected to the base 1, and a connecting strip 18 is slidably installed on the concave seat 2 16, and the top of the connecting strip 18 is fixedly installed There are two push rods 19, and arc-shaped positioning pieces 20 are fixedly installed on the top ends of the two push rods 19. The two arc-shaped positioning pieces 20 are respectively adapted to the two rotating shafts 13, and two cylinders 17 are fixedly installed in the concave seat 16. The output shafts of the two cylinders 17 are fixedly connected to the connecting strip 18. Through the extension of the output shafts of the cylinders 17, the arc-shaped positioning pieces 20 can conflict with the rotating shaft 13, thereby preventing the pay-off roller 3 from rotating naturally, thereby preventing the cable from being pulled out, and ensuring the neatness and tightness of the cable.

[0025] In the above manner, in order to enable the connecting piece 11 to linearly lift and lower with the clamping strip 12, two limit rods 1 are fixedly installed in the molded frame 9. The two limit rods 1 penetrate the two connecting pieces 11 and are slidably connected to the two connecting pieces 11.

[0026] In this method, in order to quickly replace the pay-off roller 3 and thus improve the cable laying efficiency, a card slot 21 is opened at the bottom of the two plug plates 15, and convex plates 22 are fixedly installed on both sides of the pay-off roller 3, and screws 23 are threadedly installed on the two convex plates 22. The top ends of the two screws 23 are rotatably installed with mounting plates 24, and the tops of the two mounting plates 24 are fixedly installed with clamping rods 25. The top ends of the two clamping rods 25 extend into the two card slots 21 respectively, and the two clamping rods 25 are slidably connected to the two rotating shafts 13 respectively.

[0027] The two convex plates 22 are both slidably mounted with two limiting rods 2, and the top ends of the two limiting rods 2 are both fixedly connected to the corresponding mounting pieces 24.

[0028] The working principle of the urban rail transit cable laying equipment provided by the utility model is as follows:

[0029] In this device, enough cable is already wound around the pay-off roller 3;

[0030] When laying the cable, first pass one end of the cable through the guide wheel 2 8, then through the guide wheel 1 5, and then lay it to the designated position. At this time, the cable is between the two clamping strips 12;

[0031] After laying a cable, first rotate the bidirectional lead screw 10 clockwise, the two connecting pieces 11 move toward each other, and finally use the two clamping strips 12 to clamp the cable. Then, start the output shafts of the two cylinders 17 to extend, and the connecting strip 18 will rise with the two arc-shaped positioning pieces 20, and finally close to the two rotating shafts 13, so that the rotating shafts 13 can be clamped, so that the pay-off roller 3 cannot rotate. After that, the cable can be cut from the front of the guide wheel 5. At this time, the remaining cable will not be pulled out, and the pay-off roller 3 will not rotate naturally.

[0032] When laying the cable again, the bidirectional lead screw 10 is rotated counterclockwise to loosen the cable, and then the output shafts of the two cylinders 17 are retracted to loosen the rotating shaft 13, and then the cable is pulled to lay the cable again;

[0033] When the cable on the pay-off roller 3 is used up and needs to be replaced, first start the output shaft of the cylinder 17 to extend it, use the arc-shaped positioning piece 20 to clamp the rotating shaft 13, then rotate the two screws 23, and under the limit of the limit rod 2, the two mounting pieces 24 lower the clamping rod 25 with the clamping rod 25 until the clamping rod 25 is moved out of the clamping slot 21 and the clamping rod 25 is not in contact with the rotating shaft 13, then the plug 15 on the pay-off roller 3 can be pulled out of the slot 14, and then replace it with a new pay-off roller 3 wrapped with a cable, and then rotate the screw 23 to bring the clamping rod 25 back into the clamping slot 21, and the replacement of the pay-off roller 3 is completed.

[0034] Compared with the related art, the urban rail transit cable laying equipment provided by the utility model has the following beneficial effects:

[0035] The utility model provides a cable laying device for urban rail transit. By arranging two clamping strips 12 that can be close to each other, the remaining cables can be clamped after the previously laid cables are cut off, and the output shaft of the cylinder 17 is extended, and the rotating shaft 13 is fixed by the arc-shaped positioning piece 20, so that the pay-off roller 3 will not easily rotate, and the cable will not be pulled out and dragged on the ground, which can provide good protection for the cable and make the cable neat and not scattered.

[0036] In addition, through the cooperation between the provided clamping rod 25 and the clamping groove 21, the pay-off roller 3 can be quickly replaced by rotating the screw rod 23, which can shorten the replacement speed of the pay-off roller 3 and thus improve the overall laying efficiency.
