Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a system for connecting cables such as control cables, signal cables, power cables, etc. to a moving vehicle that is equipped with a monitoring industrial television camera device and moves along a predetermined track. [Summary of the Invention] A cable drum is used to supply cables for transmitting and receiving power, control signals, video signals, etc. to a moving vehicle equipped with an industrial television camera device, etc. When using a slip ring, there is a problem that noise is generated. Furthermore, when a cable is hung on a cable hanger and moved by pulling it, there is no problem of noise generation, but there are problems such as the cable getting in the way and the need for cable storage space.

In order to solve these problems, the present invention disposes a cable leader away from a moving vehicle, and mounts a pulley and a biasing means on this cable leader.

The cable is supplied to the moving vehicle via this pulley, and the cable leader is urged in the direction opposite to the moving vehicle by the biasing means to apply the required tension to the cable.

[Conventional technology]

When using industrial television camera equipment to monitor, for example, the condition of the furnace body of a blast furnace, the treatment status of a sewage treatment plant, etc., the television camera equipment is mounted on a mobile vehicle, and the mobile vehicle is used to monitor a wide area. A device that moves the is used.

In this case, a cable (usually a cable) for transmitting the TV camera device, power supply to the moving vehicle, control signals, video signals sent from the TV camera device, etc.

It is necessary to dispose of the composite cable appropriately, such as by feeding it out or winding it up in accordance with the movement of the vehicle.

Conventionally, as a method for handling this cable, as shown in FIG. 3, there has been a system in which a cable drum 8 having a built-in slip ring brush 6 is mounted on a moving vehicle 1. This prevents the cable from sagging by winding or feeding the cable around the cable drum as the vehicle moves.

In this system, the cable end is fixed to a rotating cable drum, so signals are exchanged with the moving vehicle via slip rings and brushes.

Another type of cable drum that uses a cable drum is the fixed cable drum type, in which the cable drum is not mounted on the vehicle, but is fixed near the cable supply port, and the cable is sent out or wound up as the vehicle moves. There is something like that. A slip ring brush is also used in this case.

There was still a method, as shown in FIG. 4, in which the cable 4 was hung from a cable hanger 7 and the mobile vehicle 1 towed it.

[Problem to be solved by the invention]

The above-mentioned cable drum type uses slip ring brushes for both the drum mounted on the moving vehicle and the fixed type, so noise can get mixed into the control signal and video signal, causing malfunctions.

The quality of the surveillance images had deteriorated.The cable hanger type does not have these problems, but the cables hang down and get in the way. In addition, both types have drawbacks such as requiring a cable longer than the distance traveled.

The present invention eliminates these drawbacks and enables highly reliable signal transmission and reception to mobile vehicles and industrial television camera equipment.
Further, it is an object of the present invention to provide a cable supply processing device in which the space occupied by the cable is small and the length of the cable is short.

[Means to solve the problem]

In order to achieve the above object, the present invention installs a cable leader 2 separately from the mobile vehicle 1, and mounts a pulley and biasing means on this cable leader.

The cable is supplied to the moving vehicle via the pulley and is biased by the biasing means in a direction opposite to the moving vehicle as a cable leader, thereby applying a required tension to the cable.

[Effect]

As a result, the cable leader 2 moves by 1/2 of the distance traveled by the mobile vehicle 1, and only moves close to the cable supply port 9, so the length of the cable is determined by the distance traveled by the mobile vehicle (between both ends of the movable range). (distance along the route). Furthermore, the present invention will be described with reference to FIGS. 1 and 2. An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Figure 1 is a diagram showing the relationship between the mobile vehicle and the cable leader, Figure 2
The figure is a diagram showing the following relationship between the cable leader and the moving vehicle. 1 is a mobile vehicle equipped with an industrial television camera device 5. A cable leader 2 is equipped with a pulley 3, and a cable 4 is supplied from a cable supply port 9 to the mobile vehicle 1 via the pulley 3. The cable 4 is a composite cable that integrates a power cable, a coaxial cable, etc., and is used to transmit power to the mobile vehicle 1 and the industrial television camera device 5, control signals, surveillance video signals, etc. from the device. . 11 is a moving vehicle 1. A traveling rail on which the cable leader 2 is suspended and moved.

Reference numeral 12 denotes an electric pan head for holding the industrial television camera device 5 and controlling the direction of imaging, and a control signal is sent from the mobile vehicle 1 via a cable 13. In addition, the power supply, control signals, and video signals from the industrial television camera device 5 are sent to and received from the moving vehicle 1 via the cable 14, and the cable leader 2 applies a certain tension to the cable 4. For this purpose, a motor (not shown) with a powder clutch is incorporated as a biasing means. Note that a spring may be used instead of the motor depending on the moving distance. cable reader 2
Since the distance between the cable leader and the vehicle changes, the power source for driving the motor of the cable 15. is connected from the vehicle 1 to the cable 15 in FIG. Drum 16. Slip ring brush 17. It is supplied via cable 18.

The operation will be explained below, and FIG. 2 shows the moving vehicle 1. Cable reader 2. In order to make it easier to understand the relationship in the moving direction of the pulley 3, it is shown expanded on a plane.
