[0032] like Figure 1-7 As shown, a cable winding and unwinding device includes a tracked chassis 1, an electric-driven tracked slewing mechanism 2, a cable vehicle frame 3, a cable winding and unwinding drum 4, a continuously variable speed cable guide 5, an arc-shaped guide frame 6, and a power cabinet 7.

[0033] like Figure 1-3 As shown, the tracked chassis 1 includes a track roller 101, a carrier roller 102, a drive sprocket 103, a guide roller 104, a track 105, a grease cylinder 106, a slewing bearing 107, and a slewing reducer 108. The track roller 101 and the carrier roller 102 are respectively installed on the lower and upper parts of the chassis frame. The drive sprocket 103 is a key component that provides power to the track, while the guide roller 104 mainly guides the movement direction of the track 105. The drive sprocket 103 is installed at the power take-off shaft, and the guide roller 104 is installed at the opposite end. The track 105 is connected to the track via a connecting pin. The track 105 is connected end to end and surrounds the already installed drive wheel 103, guide wheel 104, support wheel 101, and track roller 102. The guide wheel 104 is pushed out by the grease cylinder 106 on the side of the guide wheel 104, thereby opening and tensioning the track 105. The slewing support 107 is horizontally installed on the center of the chassis frame by bolts. The cable car frame 3 is installed on the slewing support 107. The slewing reducer 108 is installed on the cable car frame 3. The slewing reducer 108 drives the slewing drive gear, thereby meshing with the internal gear ring of the slewing support. The drive wheel 103 is equipped with a motor to drive it.

[0034] like Figure 1-6As shown, the cable car frame 3 is equipped with two reel mechanisms for cable winding and unwinding. Each reel mechanism is equipped with a cable winding and unwinding reel 4. The two reel mechanisms have the same structure and function. The cable reel mounting bracket 201 is fixed to both sides of the cable car frame 3 by bolts. A common bracket is set in the middle. A cable winding and unwinding reel 4 is directly mounted on the cable reel mounting bracket 201 and the common bracket. Taking one reel mechanism as an example, the reel drive gear ring 202 is fixed on the outer end face of the cable winding and unwinding reel 4. After the reel drive reducer 203 and the rotating gear are installed, the reel drive reducer 203 is fixed on the cable reel mounting bracket 201, so that it meshes with the reel drive gear ring 202. One end of the cable reel shaft is equipped with a drive sprocket 204, which is connected to the continuously variable speed cable guide 5 through a chain 2010.

[0035] A continuously variable speed cable guide 5 is installed on the cable car frame 3 on the adjacent track side. The continuously variable speed cable guide 5 includes: a cable guide mounting bracket 205, a reciprocating lead screw 206, a lead screw fixing seat 207, a linear bearing seat 208, a driven sprocket 209, a smooth rod 2011, and a reciprocating slider 2013. The cable guide mounting brackets 205 are arranged side by side and fixed on both sides of the upper part of the cable car frame, with a shared cable guide bracket in the middle. Each adjacent shared cable guide bracket is equipped with a lead screw fixing seat 207. A smooth rod and a reciprocating lead screw 206 are arranged between the cable guide mounting brackets 205 and the shared bracket. The reciprocating lead screw 206 is fixed to the lead screw fixing seat 207 and the cable guide mounting bracket 2013. At position 5, two light rods 2011 are fixed between the cable tray common bracket and the cable tray mounting bracket 205. The arc-shaped guide frame 6 is installed on the motion component 2014. The linear bearing seat 208 and the reciprocating slider 2013 are installed inside the motion component 2014. Two sets of linear bearing seats 208 are installed on the cable tray mounting bracket 205 to cooperate with the light rods 2011 to provide guidance. A driven sprocket 209 is installed at one end of the reciprocating screw 206. The driven sprocket 209 transmits power through the chain 2010 to realize the reciprocating movement of the motion component 2014 along the axial direction of the light rod 2011 and the reciprocating screw 206, so as to realize the reciprocating guidance of the arc-shaped guide frame 6 for cable winding and unwinding.

[0036] An arc-shaped guide frame 6 is located adjacent to the outer side of a track. The arc-shaped guide frame 6 is equipped with several rollers for guiding the cable in and out. A spring roller assembly 2012 is mounted at the lower end of the arc-shaped guide frame and includes: spring 2012-1, bearing 2012-2, and rollers 2012-3. The outer circle of bearing 2012-2 is fixed to the moving component 2014. Rollers 2012-3 are connected in pairs at both ends by connecting plates. Several groups are connected top and bottom by arc-shaped springs 2012-1, with the connection point being roller 2012-3. At the 12-3 shaft end, the uppermost set of rollers 2012-3 and the inner rotating part of the bearing 2012-2 are connected by a spring 2012-1. The cable is guided by the rollers 2012-3. When the cable encounters external force during laying and winding, the spring 2012-1 deforms according to the force, and the bearing 2012-2 rotates according to the external force, thus flexibly guiding the cable and preventing right-angle bends and cable damage during laying and retrieval. This ensures smooth cable laying and retrieval.

[0037] Power cabinets 7 for providing power and control are installed on the cable trolley frames 3 of the two adjacent drum mechanisms. Power cabinets 7 can be remotely controlled. Power cabinets 7 are connected to drive the two drum drive reducers 203, rotary reducers 108, and drive wheel 103 motors. The drum drive reducers 203, rotary reducers 108, and drive wheel 103 motors can be hydraulic motors. Power cabinets 7 can be electro-hydraulic driven and connected to drive hydraulic motors.

[0038] Cable winding and unwinding process: Two drum mechanisms are used for winding and unwinding respectively. One drum mechanism is equipped with the cable to be unwound. It moves along the track and can simultaneously control one drum to wind up the old cable and the other drum to wind up the new cable. It can also be used for winding or unwinding separately. Specifically: During the unwinding operation, the track chassis 1 is remotely operated to the designated position for connection with the cable equipment. The drum drive reducer 203 is started to make the cable winding and unwinding drum 4 start to rotate clockwise to unwind the cable. The cable is guided by the guide rollers in the arc-shaped guide frame 6 and flexibly limited by the spring roller group 2012 at the end of the arc-shaped guide frame 6. The reciprocating screw 206, under the power transmitted by the sprocket group, makes the arc-shaped guide frame 6 start to engage with the cable winding and unwinding drum 4. Synchronous rotation; when encountering obstacles, the electric drive track rotation mechanism 2 drives the cable to avoid the obstruction and ensures smooth cable release; a tension control device 2015 is installed at the sprocket end of the rotating shaft in the cable winding drum 4 to monitor the cable tension in real time. If the tension is too high, the drive device will decelerate appropriately; if the tension is too low, the drive device will accelerate appropriately; during operation, the arc-shaped guide frame 6 and the meter counting device 2016 installed at its head start to count the length of the cable and accurately release the appropriate length of cable according to the actual laying requirements; monitoring systems are installed inside and outside the vehicle body, and operators can monitor the cable operation in real time through the monitoring system. The tension control device 2015 and the meter counting device 2016 are respectively connected to the power cabinet 7.

[0039] During the cable winding operation, the drum drive reducer 203 is started to make the cable winding drum 4 start to rotate counterclockwise to retract the cable. The cable passes through the arc-shaped guide frame 6 and the stepless speed-regulating cable guide 5 to avoid the cable from being misaligned or knotted.
