DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a refrigerating apparatus for refrigerating vehicles, and more particularly to a compressor that constitutes the refrigerating apparatus and a drive motor that drives this compressor with a city power The present invention relates to a refrigerating device for a refrigerating vehicle with an improved mounting structure to a vehicle body.

(Prior Art) A refrigeration system installed in a refrigeration vehicle has a compressor b driven by an engine a while the vehicle is running, as shown in FIG.
Is used to drive a refrigeration cycle including a condenser unit c, a cooling unit d, and the like, and is driven by a drive motor e separately driven by a city power source and the drive motor e while the vehicle is parked. A drive unit g including a compressor f for a city power supply is provided, and the refrigeration cycle is operated using this drive unit g. As shown in FIG. 7, these various devices include a compressor b for an engine in an engine room i of a refrigeration vehicle h, a condenser unit c in a ceiling portion k of a cab j, and a cooling unit d in a container l. A drive unit g is provided, in particular a container l
The vehicle body frame m provided below is attached to the inside or outside of the vehicle body and is fixed to the vehicle body h.

In particular, as shown in FIGS. 8 to 10, the drive unit g is attached to the bottom surface of a frame-like frame p by attaching a base plate q which is widely expanded so as to cover it. The drive motor e and the compressor f are preliminarily collectively mounted on the upper side, and the drive motor e and the compressor f are mounted on the vehicle body h in a state of being mounted on the frame p.

(Problems to be solved by the invention) By the way, in the past, the drive motor e and the compressor f were mounted on the same base plate q, and the drive motor e
Since the base plate q in which the compressor f and the compressor f are mounted together is attached to the vehicle body h in a state where the base plate q is attached to the frame p, the weight is considerably heavy and the attachment work is dangerous. In addition, the compressor f and the drive motor e
The frame p for accommodating and was collectively large in size, and the mounting workability was not good. Further, particularly in a vehicle such as a light vehicle that cannot secure a sufficient mounting space, the mounting layout may make it difficult or impossible to mount with such a large frame p.

The present invention was devised in view of the above-mentioned problems, and provides a refrigerating device for a refrigerating vehicle capable of improving the mountability of a drive unit for a commercial power supply including a drive motor and a compressor. The purpose is to

[Configuration of Device] (Means for Solving Problems) In a refrigeration system for a refrigeration vehicle having a mounting base for mounting a drive motor driven by a city power supply and a compressor driven by the drive motor on a refrigeration vehicle The pedestal is divided into a motor mounting frame for mounting a drive motor and a compressor mounting frame for mounting a compressor.

(Operation) To describe the operation of the present invention, the mounting frame is divided into a motor mounting frame for mounting a drive motor driven by a city power supply and a compressor mounting frame for mounting a compressor driven by the drive motor. Thus, the drive motor and the compressor can be separately attached to the vehicle body.

(Embodiment) A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, reference numeral 1 is a drive motor driven by a city power source, and a compressor 2 is arranged adjacent to the drive motor 1 to form a drive unit 16. In the present embodiment, the compressor 2 and the drive motor 1 are connected by a belt 5 spanning between a pair of pulleys 3 and 4 provided respectively, and the compressor 2 is belt-driven by the drive motor 1. It has become so.

By the way, the mounting base 6 mounted with the drive motor 1 and the compressor 2 configured as above and mounted on the vehicle body is
It is configured by being divided between the drive motor 1 and the compressor 2, and these parts respectively form a motor mounting frame 7 on which the drive motor 1 is mounted and a compressor mounting frame 8 on which the compressor 2 is mounted. Motor mounting frame 7
Is a bottom plate 9 on which the drive motor 1 is installed, and side plates 10 that stand upright from the other three sides of the bottom plate 9 except one side on the adjacent compressor 2 side so as to surround the drive motor 1.
Composed of and. Also, compressor mounting frame 8
Is composed of a bottom plate 11 on which the compressor 2 is installed, and side plates 12 that surround the compressor 2 and are erected from the other three sides of the bottom plate 11 except one side on the adjacent drive motor 1 side. It And these frames 7, 8
Is mounted with the drive motor 1 and the compressor 2 respectively, and these mounting spaces 13 and 14 are communicated with each other to form an integral mounting space.

Further, as shown in the figure, the frames 7 and 8 are provided with a mounting plate 15 for mounting the frames 7 and 8 on the vehicle body by straddling them. The mounting plate 15 includes side plates 10 and 1
2 is formed with an L-shaped cross section that engages with the upper edge of the side plate 1.
Nos. 0 and 12 and the side surface portion 15a that is in contact with the Nos. 0 and 12 are bolted to support the frames 7 and 8 collectively. The mounting plate 15 is provided on the upper surface 1 facing the vehicle body.
5b is bolted to the vehicle body side to mount and support the entire frame 7, 8 and the like on the vehicle body.

Next, the operation of the embodiment will be described.

When the drive unit 16 including the drive motor 1 and the compressor 2 is attached to the refrigeration vehicle, the drive motor 1 and the compressor 2 are previously mounted on the motor mounting frame 7 and the compressor mounting frame 8, respectively. Next, the mounting plate 15 is fixed to the vehicle body. Finally, the motor mounting frame 7 and the compressor mounting frame 8 are attached to the mounting plate 15.
The drive unit 16 can be mounted on the vehicle body by separately mounting and temporarily mounting and then bolting.

According to the above configuration, the drive motor 1 and the compressor 2 are separately mounted on each of the divided frames 7 and 8, and the mounting work can be performed in a compact and lightweight state. Further, various mountings can be adopted according to the mounting layout of the vehicle.

When the mounting space on the vehicle body side is sufficiently secured and the drive motor 1 and the compressor 2 as a whole can be mounted together, the drive motor 1 and the compressor 2 are mounted on the frames 7 and 8, respectively, and then these frames are mounted. It is also possible to integrally mount 7, 8 on the mounting plate 15 in advance in the vehicle body.

Incidentally, as shown in FIG. 1, FIG. 2, FIG. 4 and FIG.
In the pulley 4 of the compressor 2 used in this embodiment,
A blade 17 for cooling air blowing is attached integrally.

Since the drive unit 16 driven by the city power supply is mounted below the container where ventilation is not good and is driven while the vehicle is parked, the compressor 2 cannot be properly cooled and the compressor 2 is overheated. You can't exert your full potential. In addition, there is a problem that it is necessary to secure a sufficient installation occupation space in order to obtain sufficient ventilation.

On the other hand, particularly in the case where the drive unit 16 has a closed structure, it is known that a cooling fan and a fan motor are separately provided, but this is preferable because it causes an increase in cost, a complicated assembly, and an increase in size of the unit. It wasn't something.

Therefore, in this embodiment, the blades 17 are integrally provided on the pulley 4 of the belt-driven compressor 2 so as to be axially overlapped. In this way, the power of the drive motor 1 can be used to drive the blades 17 to send the cooling air to the compressor 2, and the compressor 2 can be prevented from overheating and its performance can be sufficiently exhibited. . Particularly, in the present embodiment, the power of the drive motor 1 can be used, and the operation can be performed at low cost. Further, since the blades 17 are provided on the pulley 4 that is driven during compressor operation, operation control of the blades can be performed easily and appropriately. Further, since the blade 17 is integrally provided on the pulley 4, it can be easily attached.

The pulley 4 and the blade 17 may be integrally molded as a whole, or may be separately manufactured and assembled by fastening them with a bolt or the like.

[Effects of the Invention] In short, according to the present invention, the following excellent effects are exhibited.

(1) The mounting base is divided into a motor mounting frame and a compressor mounting frame so that the drive motor and compressor can be mounted separately on the vehicle, so they can be mounted easily and safely in a compact and lightweight state. You can do the work.

(2) It can be mounted according to the layout of the vehicle, and can be properly mounted even in a light vehicle or the like, which has a small mounting space.
