[rotary rack]

Fig. 2 is the stereogram for showing rotary rack 31.

In fig. 2, rotary rack 31 possesses bottom plate 311, a pair of the main frames erected on bottom plate 311 312nd, the crossbeam 313 on bottom plate 311 is erected in the way of intersecting with main frame 312, is set up in a pair Upper plate 314 between the upper end of main frame 312 and as can pitching chassis of supporting driver platform 32 scaffold The first scaffold 315 and the second scaffold 316.

A pair of main frames 312 make rear end side set in parallel to each other, and with from rear end side side forward The mode of mutual narrower intervals is extended.

First scaffold 315, as also shown in Figure 3, possesses from the main frame 312 in left side to overall width direction The extended extended portion 315A in outside and located at extended portion 315A upper surface and to driving Platform 32 carries out the support 315B of e axle supporting.Extended portion 315A has the U-shaped being open downwards The cross sectional shape of shape, electrical appliance 5 is contained in the space S formed by the U-shaped.Support 315B is formed as L-shaped, and e axle supporting is carried out to the leading section of bridge 32 in its upright portion.

Second scaffold 316 is erected on the position of the side of main frame 312 on the right side on upper plate 314, right The leading section of bridge 32 carries out e axle supporting.

[electrical appliance]

Fig. 4 and Fig. 5 are the stereogram and side view for showing electrical appliance 5.

In Fig. 4, Fig. 5, electrical appliance 5 possesses the register (レ ジ ス タ) as electrical equipment 51st, as the loudspeaker 52 and installing component 53 of electrical equipment, register 51 and loudspeaker 52 are installed on Fill part 53 and carry out blocking.

Register 51 is for making the superfluous of hydraulic pump function when vehicle body controller 37 there occurs failure Remaining circuit, is the controller that the electric current of opposite hydraulic pressure pump flowing is limited.Via the register 51, liquid Press pump is connected with battery 38.In the present embodiment, register 51 is resistor, will from battery 38 to A part for the electric power of hydraulic pump conveying is converted to heat energy releasing.

Installing component 53 possesses flat part 531, the bending section 532 bent relative to flat part 531 and set Support 533 on the face of a side of flat part 531.

Flat part 531 and bending section 532 are by constituting the part of the tabular of end bending, mutually by one Shaping.

On the face of the side of support 533 of flat part 531, the company for register 51 and distribution is fixed with Connect device 54.In the present embodiment, across support 533, connector 54 is fixed on the side of bending section 532 Position, register 51 is fixed on to the position of the opposite side of bending section 532.

Bending section 532 is bent to the side (rear side) opposite with support 533.The bending section 532 has There is the mounting hole 532A for the bracket 55 for installing distribution holding, distribution is kept via the bracket 55.

Support 533 is formed by making plate-shaped member bend to stair-stepping part.The support 533 is in step difference Orientation (step difference direction) towards welding a side in step difference direction in the state of above-below direction It is connected to flat part 531.The another side of support 533 is configured in the front interval of flat part 531, Loudspeaker 52 are fixed on the another side.

[contained structure of electrical appliance]

As shown in Figures 3 to 5, electrical appliance 5 is contained in by the extension of the first scaffold 315 The space S that setting unit 315A is surrounded, installing component 53 is fixed on extended portion 315A using bolt 56 On.Now, in electrical appliance 5, its front, top and rear are by the first scaffold 315 Covering.Further, since register 51 is located at position closer to the top compared to loudspeaker 52, i.e., electric Be located at the top in the electrical equipment of unit 5, even if therefore the heat that is produced by register 51 rise, Also heat transfer can be prevented to the loudspeaker 52 of lower section.

On the other hand, loudspeaker 52 are located at position more on the lower compared to the lower end of the first scaffold 315, Expose outside to the space S formed by the first scaffold 315.By so configured loudspeaker 52, prevent The sound that loudspeaker 52 send is stopped to be blocked by the first scaffold 315, has made the sound of loudspeaker 52 effectively Transmit forwards.

In addition, in installing component 53, extension of the bending section 532 compared to the first scaffold 315 is set The front end for putting portion 315A is located at more outward position, exposes to the outside of space S.Therefore, it is possible to incite somebody to action The bracket 55 of distribution holding is installed on bending section 532, and distribution can be made to be maintained at curved via the bracket 55 Pars convoluta 532.

[effect of embodiment]

Present embodiment from the description above, with following effect.

That is, surrounded because at least a portion of electrical appliance 5 is contained in by the first scaffold 315 Space S, therefore, it is possible to effectively using rotary rack 31 space, it is ensured that it is electric on rotary rack 31 The configuration space of equipment.

[variation]

Note, the invention is not restricted to foregoing embodiment, in the range of the purpose of the present invention can be achieved Deformation, improvement etc. be contained in the present invention.

For example, in said embodiment, making loudspeaker 52 to the space formed by the first scaffold 315 S outside is exposed, and a part for electrical appliance 5 is contained in into space S, but it is also possible to will whole electricity Gas unit 5 is contained in space S.

In said embodiment, electrical appliance 5 is contained in and surrounded by the first scaffold 315 Space S, but it is also possible to electrical appliance 5 is contained in the space surrounded by other scaffolds.Example Such as, the second scaffold can also be constituted identically with the first scaffold 315, by electrical appliance 5 It is contained in the space surrounded by second scaffold.

In said embodiment, the extended portion 315A of the first scaffold 315 is downwardly open, but Can also upward, horizontal direction, other direction openings.

In said embodiment, scaffold is formed as U-shaped but it is also possible to be other shapes, only There is the space surrounded by scaffold, for example, it is also possible to scaffold is formed as into hollow form, Electrical appliance 5 is contained in the hollow space.

In said embodiment, electrical appliance 5 is that register 51 and loudspeaker 52 are carried out into unit The structure of change is but it is also possible to be the structure that other electrical equipments are carried out to blocking.In addition, electrical equipment Multiple electrical equipments can not also be installed on installing component and carry out blocking by unit 5, but to electrically setting Standby upper other electrical equipments of installation carry out blocking.Also, electrical appliance 5 is made including register 51 It is controller but it is also possible to be other controllers, for example, it is also possible to including vehicle body controller 37.

In said embodiment, register 51 is made up of but it is also possible to be electronic control type resistor Structure.

Installing component 53 can also be other shapes, as long as multiple electrical equipments can be installed.

For example, installing component 53 can also have the tongue extended downward from the lower end of flat part 531 Piece portion, regard the tongue piece portion as support.Alternatively, it is also possible to which loudspeaker 52 are fixed on into flat part 531.

In addition, bending section 532 can also be bent to the identical side (front side) of support 533.

As long as building machinery possesses the structure for the scaffold that e axle supporting is carried out to bridge, do not limit In hydraulic crawler excavator, for example, it is also possible to be dump truck.

The present invention is in addition to it can be used in building machinery, additionally it is possible to for be configured to make bridge relative to Vehicle body frame can pitching other mechanically movings.
