Description

[Detailed Description of the Invention] This invention is applicable to electronic relay vehicles such as TV relay vehicles, telephone line mobile switching vehicles, mobile radio vehicles, satellite communication receiving vehicles, and satellite communication transmitting vehicles, which have an operation room behind the driver's cab. Relating to a specially equipped vehicle equipped with a rack for storing equipment.

As shown in Figure 1, in a typical TV broadcast vehicle called a conventional large broadcast vehicle, the driver's cabin is
Behind the sub-adjustment room 2 is provided as an operation room for editing programs, adjusting the color of the television camera, etc. Behind the sub-adjustment room 2 is a generator room 3. The generator room 3 further houses a cable drum 4, a storage shelf 5, and a cooling compressor 6. In the sub-adjustment room 2, racks 8A, 8B, 8C, 8D, 8E, 8D, 8E, 8D, 8E, 8C, 8B, 8C, 8D, 8E, etc.
8F, 8G, and 8H are fixed, and adjustment equipment storage racks 8J and 8K are fixed to the rear of the left side wall 9. A director's seat 10 and a switcher's seat 11 are fixed to the left wall 9 facing the adjusting equipment storage racks 8A to 8C at the front of the right wall 7, and the space between these seats 10, 11 and the racks 8A to 8C is fixed. A switcher table 12 is arranged.

Maintenance of the adjustment equipment 13 stored in the adjustment equipment storage racks 8A to 8K is generally performed on the back side of the adjustment equipment storage racks 8A to 8K.
A large number of doors (not shown) for maintenance are provided at positions corresponding to 8K. The weight of these doors is much greater than the weight of the side walls 7 or 9 of the same area, and in order to compensate for the decrease in strength of the vehicle body due to the provision of openings for mounting the doors, the side walls 7 and 9 are
is provided with a number of reinforcements. For this reason, the vehicle weight of the relay vehicle becomes extremely large, and the required horsepower also increases. Furthermore, along one side wall 9 there are seats 10,
11, more racks 8A to 8H are arranged along the other side wall 7, and the weight of the left and right sides of the vehicle is usually in a ratio of about 2:3, resulting in an extremely unbalanced balance. Driving performance deteriorated. In addition, since the adjustment device 13 hates moisture,
The door has a sealing structure, is complicated and expensive, and opening the door and maintaining the adjustment device 13 in case of rain or the like becomes extremely troublesome work. Moreover, each adjustment device 13 is located higher than the floor of the sub-control room 2, so in order to maintain the adjustment device 13 from outside the vehicle, a stepladder or a dedicated platform is required. When using a platform, the work area is limited, and when using a stepladder, the work must be done with poor footing.

The sub-control room 2 consists of a program production section 14 centered around a switcher console 12, and a technology section 15 for color matching and audio adjustment of multiple television cameras.
Close communication is required between the workers in Section 4 and those in Technical Section 15. However, in the sub-adjustment room, voices at various adjustment stages are output from speakers, making it difficult to communicate intentions only orally. It is also difficult to communicate visually in the sub-control room 2 in which the program production section 14 and the technical section 15 are arranged side by side in the horizontal direction of the workers. For this reason, conventionally the sub-control room 2
There was insufficient communication within the company, and each worker required a high level of skill in order to produce excellent programs. Furthermore, with such an arrangement of the sections 14 and 15, when a worker in the technical section 15 enters the program production section 14, the visibility of the worker in the program production section 14 is obstructed;
On the other hand, in the technical section 15, the right wall 7
The work of moving around in the space between racks 8D to 8H along the left side wall 9 and racks 8J and 8K along the left wall 9 is itself complicated, and if a worker from program production section 14 enters into such a situation. The workability is significantly impaired.

Such problems regarding operability, maintenance workability, vehicle weight, vehicle weight balance, and manufacturing cost similarly exist in other specially equipped vehicles.

This invention was devised to solve the above-mentioned conventional problems, and it reduces the weight of the vehicle, improves the left-right weight balance, improves the workability of adjusting equipment maintenance, improves the workability of the operation room, and improves the workability of the operator inside the operation room. The purpose is to provide a specially equipped vehicle that can realize closer mutual communication.

The specially equipped vehicle according to the present invention has racks for storing equipment arranged at both ends of the operation room in the front and rear directions, each rack extending in the width direction of the vehicle, and work sections arranged back to back to form the operation room in the form of one room. , and improve the left and right balance of the vehicle.Furthermore, each rack is moved forward and backward by a traveling device, or rotated horizontally by a rotary drive device, and each rack is moved in the operation room. This allows workers to enter the back of the machine.

Next, a first embodiment of a specially equipped television relay vehicle according to the present invention will be described with reference to the drawings. In the drawings, parts that are the same as or equivalent to those of the conventional example are designated by the same reference numerals.

In Figures 2 to 6, the sub-control room 2 of the relay vehicle
The generator room 3 is provided in a box loading platform 23 that is independent from the operator's cab 1, and the corners of the box loading platform 23 are provided with a relatively small radius chamfer, and are generally rectangular in shape to accommodate adjustment equipment. The storage rack can be provided at a sufficient height even at the end of the box loading platform 23. The sub-control room 2 and the generator room 3 are the box loading platform 2.
3 and are separated from each other by a sound insulating wall 24. As a result, the transmission of noise from the generator 16 into the sub-control room 2 is significantly reduced, and the livability and workability of the sub-control room 2 are improved.

In the sub-adjustment chamber 2, adjusting device storage racks 8A to 8C and 8D to 8F extending in the vehicle width direction are arranged at both ends in the longitudinal direction, and the left and right weights of the vehicle are set equally. This has significantly improved the driving performance of the broadcast vehicle. Furthermore, by extending the racks 8A to 8F in the vehicle width direction, the overall length of the vehicle is significantly reduced, from the conventional total length of about 7 m to about 5 m. Therefore, the relay vehicle can be made smaller and lighter. Moreover, since each of the racks 8A to 8F is set sufficiently high, the number of adjustment devices 13 that can be stored is almost comparable to that of a conventional relay vehicle.

The generator 16, cable drum 4, and other equipment are stored in the generator room 3, and by opening the rear door 25, the cable can be pulled out, the generator 16 can be maintained, and other equipment can be taken out and stored. I can do it. The cable drum 4 is driven by a motor 27 via a chain 26, so that the cable can be easily pulled out and wound up.

As shown in FIG. 7, racks 8A to 8C are installed on a traveling device 28, and racks 8D to 8F are also installed on a similar traveling device (not shown).

The traveling device 28 has a gearbox 30 and a motor 31 mounted on both sides of a frame-shaped truck 29, and rails 32 capable of supporting the truck 29 are laid on the floor of the sub-adjustment chamber 2. Furthermore, racks 33 are installed on the floor of the sub-control room 2 along both sides of the trolley 29.
is fixed, and a pinion (not shown) that meshes with this rack 33 is built in the gear box 30. This pinion is driven by the motor 31 and rolls along the rack 33, causing the truck 29 to travel in the front and back direction. Rack 3
A limit switch 34 is arranged near the front and rear ends of the truck 29, and the running of the truck 29 is controlled by a gear box 30.
It is stopped when it touches the limit switch 34. Wheels 35 are pivotally attached to the trolley 29 so that it can run smoothly on the rails 32. Stoppers 36 are fixed to the front and rear walls of the sub-adjustment chamber 2 to buffer against collisions of the cart 29 with the walls. Rack 8A includes starting the motor 31 in a desired rotational direction;
and a remote switch 3 that can control its stop.
7 is detachably connected to ensure good operability of the traveling device 28.

A passage 38 is provided at the lower part of the rack 8B, allowing passage in the front and rear directions, and when the racks 8A to 8C are running backwards, an operator can enter behind the racks 8A to 8C through the passage 38.

Therefore, there is no need to provide the sub-control room 2 with a door for maintenance of control equipment as in the past, which reduces the weight of the vehicle, reduces manufacturing costs, and improves rain protection. Good workability of adjusting equipment maintenance work at any location can be guaranteed. Fluorescent lights 39 that project illumination light obliquely upward are provided on the floor near the front and rear walls of the sub-adjustment room 2, so that maintenance of the adjustment equipment can be performed under sufficient illumination.

As shown in Fig. 3 and Fig. 7, the sub-control room 2
A cable duct 41 is drilled in the floor of the building, and when the racks 8A to 8C and 8D to 8F run, the cables connected to each track 8A to 8F rise freely from the duct 41, and when the racks 8A to 8F run, the cables connected to each track 8A to 8F stand up freely. It has become unobstructed.

As shown in Figures 3 and 8, Rack 8A
Switcher consoles 12 are installed in racks 8D to 8C, and VE consoles 19 are installed in racks 8D to 8F. Production section 1
Mutual interference in the working space between the workers in section 4 and the workers in technical section 15 is minimized. Moreover, since the workers in both sections work in relatively close positions, mutual communication between the workers becomes closer.

Furthermore, as shown in Fig. 8, in this relay vehicle, the left and right side walls 7 and 9 are not hidden by racks, so for example, the side wall 7 has a large area that was unimaginable with conventional relay vehicles. It is also possible to provide a window 40.

Next, a second embodiment of the television relay vehicle of the present invention will be described based on the drawings. In this embodiment, like the first embodiment, adjustment equipment storage racks are arranged at both ends of the sub-adjustment chamber in the longitudinal direction, and each adjustment equipment storage rack extends in the vehicle width direction.
Each rack moves in a different manner. Since the front and rear adjustment equipment storage racks have the same structure, only the rear adjustment equipment storage rack will be described.

In FIGS. 9 and 10, adjustment equipment storage racks 8L and 8M are arranged separately on the left and right,
Each rack 8L, 8M is pivotally connected at its outer side front by a shaft 42 to the floor and ceiling of the sub-control room. A rotary drive device 43 is provided at the inner lower part of the racks 8L, 8M, and the racks 8L, 8M are driven by this drive device 43 so that they can rotate horizontally about a shaft 42. There is.

An arcuate rail 32 is laid on the floor of the sub-control room, and the rotary drive device 43 drives the racks 8L and 8M while being in contact with this rail 32. The rotary drive device 43 pivotally supports wheels 45 via a gearbox 44, and the wheels 45 are driven by a motor 47 via a worm gear 46. A worm gear 48 is formed at the center of the wheel 45 in the width direction, and contact portions 49 made of a high friction material such as rubber are provided on both sides of the worm gear 48. wheel 4
5 is driven by a worm gear 48 and contacts the rail 32 at a contact portion 49.

Even in such a configuration, racks 8L, 8M
Since the rear side of the adjustment equipment can be exposed to the operator, maintenance of the adjustment equipment can be easily performed in the sub-adjustment room.

In the second embodiment, the racks 8L and 8M are rotated in a double-folding configuration, but in the third embodiment shown in FIGS. 11 and 12, the racks are rotated in a single-sided configuration.

In Figures 11 and 12, Rack 8N
is pivotally connected to the floor and ceiling of the sub-adjustment room by a shaft 42 at the front part of one side, and can be rotated along the rail 32 by a rotary drive device 43 provided at the lower part of the other side.

The rotational drive device 43 drives the wheels 45 by a motor 47 via a small gear 50.
A large gear 51 that meshes with a small gear 50 is formed at the center of the wheel 45 in the width direction. and wheel 4
Contact portions 49 similar to those in the second embodiment are provided on both sides of the large gear 51 in FIG.

In this embodiment, the same effects as in the second embodiment can be obtained, but the rack 8L in the second embodiment,
Since the 8M gap is not required, the third embodiment is advantageous in terms of effective use of space.

As mentioned above, the specially equipped vehicle according to the present invention has racks for storing equipment arranged at both ends of the operation room in the front and rear directions, each rack extending in the width direction of the vehicle, and work sections arranged back to back, making the operation room into one room. In addition, each rack is configured to have a horizontal structure, improving the balance between the left and right sides of the vehicle, and can be operated by moving each rack in the front and rear directions using a traveling device or rotating each rack horizontally using a rotary drive device. Since it is possible for workers to enter the back of each rack inside the room, it reduces vehicle weight, improves the left-right weight balance, improves the workability of adjusting equipment maintenance, improves workability in the sub-adjustment room, and improves the workability of the sub-adjustment room. This has the excellent effect of realizing closer communication between workers.
