Description of the Related Art When manufacturing a power CV cable in which the conductor has a large diameter and the operating voltage tends to increase, a non-crosslinked insulation coating extruded on the conductor is run in a cable continuous crosslinking device to continuously crosslink the cable. It is important to have high reliability so that no disconnection occurs in the conductor or its connection part when connecting the cable, but in a vertical cable continuous bridge device, the belt wrap cap with the conductor connection part located at the top is used. When passing through a stun (metering capstan), the conductor connecting fitting is bent with a curvature of the capstan diameter, or the tension increases due to the weight of the cable with a thick conductor diameter, or the bridge pipe due to an increase in the bridge pressure. Due to the increase in tension due to the increase in piston pressure at the outlet, the load applied to the conductor and connecting fittings may become high, resulting in a disconnection accident.

険防止の効果的な対策は講じられていなかった。The disconnection accident of the conductor connecting portion in the vertical continuous bridge device as described above often occurs in the metering capstan portion where the tension increases, and the uppermost meter of this bridge device is often used. When the conductor connection part is cut at the ring capstan part, the cable falls and jumps out of the bridge pipe, protrudes beyond the winding capacity to the winding side, and hits the surrounding equipment and walls such as walls and stops. There is a risk of injury if anyone is present in this area. For this reason, in the past, although the accident of cutting the conductor connecting portion was prevented, effective measures for preventing the danger in the event of the cutting accident have not been taken.

It is an object of the present invention to provide a continuous bridge device with a cable drop prevention device that prevents the cable from falling and avoids the danger of the cable popping out.

ものである。In order to achieve the above object, a continuous bridge device with a cable drop prevention device of the present invention is a vertical type or an inclined type in which a conductor is installed vertically or at an angle and a conductor runs downward. In the continuous cable bridge device D, the conductor breakage detection device 5 for detecting the breakage of the conductor A is installed above the traveling path where the conductor A descends, and the conductor breakage detection device 5 detects the breakage of the traveling conductor A. A cable clamp device 6 for gripping and fixing the conductor A or the insulation-coated cable C by a detection signal output at times is installed in at least one position of the traveling path of the conductor A and the cable C.

ーブルの落下が防止される。When the conductor A running through the continuous cable bridge device D is cut while passing through the upper position of the conductor descending path, for example, the metering capstan installed at the uppermost position, the cut conductor A and the lower position are preceded. Although the insulation-covered cable portion C tries to fall in the bridge device, the conductor disconnection detection device 5 installed above the conductor descending path immediately detects the disconnection of the conductor A and outputs a detection signal. As a result, the cable clamp device 6 operates to immediately grasp and fix the conductor A portion or the insulation-coated cable C portion that is to be cut and dropped, so that the conductor and the insulation-coated cable are prevented from falling.

FIG. 1 shows an example of a continuous cross-linking device with a cable drop prevention device according to the present invention, where A is a conductor, C is a cable in which an extruded insulation coating B is extrusion-coated on a conductor A, and D is a continuous cross-linking device. is there. The conductor A is supplied from the conductor winding drum of the supply stand 1 installed in the basement g, and is supplied to the turn guide 2
Through the metering capstan 3 installed on the uppermost floor h, the metering capstan 3 holds the belt wrap 4 to control the sending speed, and the upper half circumference of the metering capstan 3 is controlled. When it crosses over the surface, it changes direction and descends, passes through the cable cutting device 6 through the conductor cutting detection device 5 installed immediately below the metering capstan 3, and crossheads of the extruder 7 installed on the intermediate floor j. An insulating coating B, such as uncrosslinked rubber or plastic, is extrusion-coated around the conductor through the wire 8. The insulation-coated cable C extrusion-coated with the uncrosslinked insulation coating B descends in the heated crosslinking tube 9 and the cooling tube 10 connected to the lower end of the heating bridged tube 9 so that the inside of the tube does not foam to about 10 kg / cm 2. The lower end of the cooling pipe 10 is heated by steam or heated inert gas to crosslink the uncrosslinked insulating coating while descending the heating bridge pipe 9, and cooled by water or cooling gas while descending the cooling pipe 10. After turning through the roller 12 of the turn sheave 11 provided in the basement g, the direction is changed in the horizontal direction in the basement g, and the end seal 13 that seals the pressure inside the pipe at the outlet end of the cooling pipe 10 goes out of the pipe. The insulation-coated cable C running out of the pipe passes through the cable clamp device 16 having the same configuration as the cable clamp device 6 described above, is taken up by the take-up machine 14 and taken up by the take-up machine 15. The cable clamp device 16 provided after the end seal 13 is provided as needed and can be omitted.

この切断を検知するとその検知信号を出力する。As shown in FIG. 2, the conductor cutting detection device 5 has two pairs of conductor guide rollers 16 and 1 facing each other.
An optical sensor 20 composed of a light emitter 21 and a light receiver 22 is provided between 7 and 18, 19 and is installed immediately below the metering capstan 3 so that the conductor A runs downward in the direction of the arrow. When passing through, the light transmitter 21 and the light receiver 22 of the optical sensor 20 detect whether or not the passing conductor A or the conductor connecting portion is disconnected. When the uncut conductor A continuously passes between the light emitter 21 and the light receiver 22, the light emitted from the light emitter 21 is blocked by the passing conductor A and is not received by the light receiver 22, so that the output of the optical sensor 20 is output. Although there is no signal, if the conductor A or the conductor connecting portion is cut when it passes through the metering capstan 3, there is no conductor portion to pass between the light emitter 21 and the light receiver 22, so that the light emitted by the light emitter 21 is projected by a chained arrow. When the light is received by the light receiver 22, the disconnection is detected. When detecting the disconnection, the conductor disconnection detection device 5 outputs the detection signal.

It is configured such that the conductor A and the cable C are narrowed and clamped between the peripheral edge gripping portions 23 and 24 facing each other. The cable clamp devices 6 and 16 need to be installed in at least one position of the running paths of the conductor A and the cable C.
