Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to the wall structure of a vehicle cab.

[Technical background and problems of the invention]

Figure 1 shows a front view of a locomotive of a special vehicle (coke carrier) in which the driver's cab 1 protrudes to the side of the vehicle. As shown in the figure, it is composed of an outer panel 2, a column structure 3, and inner lining plates 6, 6A, 6B, etc., and the outer panel 2 and column structure 3 are each welded, and several types of electrical equipment 7, 7A, 7B. In order to attach..., a large number of equipment mounting brackets 4 were welded to the inner surface of the outer panel 2. Then, when assembling, the pillar structure 3 is placed inside the outer panel 2.
Insulating material 5, 5A, 5 of a size corresponding to the compartment area of
Insert the thin lining plates 6, 6A, 6B...
After closing each electrical device 7, 7A, 7B... with a bolt screwed into the screw hole of the device mounting bracket 4 through the hole of the lining plate 6, 6A, 6B... . However, with such a wall structure, the column structure 3 and the numerous equipment mounting brackets 4 are welded to the outer panel 2, so a lot of welding distortion occurs in the outer panel 2, and the work to remove this distortion is difficult. Therefore, it was difficult to finish the outer panel 2 neatly. Further, when inserting the heat insulating materials 5, 5A, 5B, etc. during assembly, it is necessary to provide a large number of cut-out holes in the heat insulating materials to match the metal fittings 4, and this cutting work is also troublesome. Furthermore, electrical equipment 7, 7A, 7B...
When wiring, the electric wire 8 must be passed through the electric wire insertion hole provided in the pillar structure 3 as shown in FIG. 3, which has the disadvantage that the wiring work is time-consuming. Furthermore, even after the interior and exterior panels of the driver's cabin have been painted, additional equipment may need to be installed inside the driver's cab 1 due to additional specifications, etc., but even in that case, the equipment must be installed on the exterior panel 2, which has already been painted. Since the mounting bracket 4 is newly additionally welded to attach the equipment, there is a drawback that distortion of the outer panel 2 must be corrected and repainted, etc.

[Purpose of invention]

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional method, and its purpose is to prevent the negative effects of welding to the outer panel, and to facilitate the installation and wiring of insulation materials and electrical equipment. To provide a wall structure for a vehicle cab that allows for

[Summary of the idea]

In order to achieve the above object, this invention consists of a thick plate with a bent edge only on the outer side, and electrical equipment is directly attached to the thick plate lining, unlike the conventional column structure and many This eliminates the need for equipment mounting brackets, eliminating the problem of distortion caused by welding to the outer panel, and providing openings necessary for inserting insulation material and wiring equipment into the thick lining of the thick plate, making it easier to install insulation material and wire. The present invention is characterized in that the work can be easily performed, and that the opening can be closed in an attractive manner when an electric device is attached.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings in FIGS. 4 and 5. FIG. 4 is an internal view of the wall of the vehicle driver's cab 1 showing the same part as FIG. 2, and FIG. 5 is a cross-sectional view taken along the - line in FIG. 6' indicates the inner lining. This lining 6'
is composed of a thick plate, for example, about 3 to 9 mm thick, which has bent edges 16A, 16B, and 16C only on the outer sides (both vertical sides and the concave upper side). Openings 9, 9A, 9B, 9 necessary for inserting insulation materials 5', 5A', 5B'... and wiring electric wires 8
C, 9D are provided, and screw holes 10 are drilled in the four corners of each opening for linearly tightening and fixing the electrical devices 7, 7A, 7B... to the thick plate lining 6' with bolts 11. ing. Note that the opening 9,
9A to 9D are neatly closed off so that they cannot be seen from the inner surface by attaching the electrical devices 7, 7A, 7B, . . . .

[Effect of idea]

Since the wall structure of the vehicle cab of this invention is as described above, it produces the following effects.

(1) Since the structure is such that electrical equipment is directly attached to the inner lining of the thick plate, the conventional column structure and numerous equipment mounting brackets are no longer necessary, simplifying the structure and reducing distortion caused by welding the metal fittings to the outer plate. This eliminates the problem of distortion, and there is no need to perform distortion removal work.

(2) The thick plate lining has an opening of the size necessary for inserting the insulation material and wiring, and the insulation insertion part does not have conventional equipment mounting brackets;
Since the interior space of the thick plate lining is not divided into columns as in the past, installation of heat insulating material and wiring work can be easily performed.

(3) Even if equipment is added due to specification changes, additional work can be done by simply drilling mounting screw holes and wire holes in the inner lining, and no processing is required on the outer panel, making it easier to install than conventional methods. Much more efficient. In addition, there is no fear of distortion occurring on the outer panel due to rewelding, and the final appearance of the finished product can be surely improved.
