Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an exhaust system structure for an engine used in a refrigerated shipping container.

(Prior Art) Refrigerated shipping containers have been used to store frozen foods and transport them to various locations.
Such a freezing container is comprised of a container that stores frozen foods and the like, and a refrigeration device that cools the inside of this container.

As such a refrigeration system, one that includes an internal combustion engine and a refrigerant compressor driven by the internal combustion engine is generally known (see, for example, Japanese Patent Laid-Open No. 58-67532). In such conventional devices, the refrigeration device is usually attached to a container, and the exhaust pipe of an internal combustion engine provided in the refrigeration device is connected to a silencer attached to the container.

In addition, the container to which the above-mentioned refrigeration equipment is attached is generally mounted on a trailer vehicle, and
The refrigeration equipment is connected and attached to the container by a complicated mechanism.

By the way, if only the container is removed from the trailer and loaded onto a cargo ship, for example, the generator installed on the ship can be used, so there is no need for a heavy internal combustion engine or power generator. Remove the engine exhaust pipe from the silencer,
It is necessary to remove the drive unit including the internal combustion engine from the container. Also, in some cases, it may be necessary to remove the refrigeration equipment from the container for maintenance or replacement. However, as mentioned above, the refrigeration system is connected to the container by a complicated mechanism, especially in the engine exhaust system.
Since the engine on the refrigeration equipment side and the silencer on the container side are connected by a connected exhaust pipe, when trying to remove the frame, the exhaust pipe interferes with the side wall of the refrigeration equipment frame, making it difficult to remove. The removal or installation work described above is troublesome and not easy.
The workability of attaching and detaching the refrigeration equipment and the container is not good.

(Purpose of the invention) The present invention was made in view of the above-mentioned conventional problems, and aims to improve the workability of attaching and detaching the refrigeration equipment frame from the container and the engine from the refrigeration equipment frame. The purpose of this invention is to provide an exhaust system structure for a refrigerated container engine.

(Structure of the invention) The present invention provides a refrigerating equipment frame equipped with a refrigerating equipment and a drive unit including an engine for driving the refrigerating equipment in a recessed space formed at one end of the container. On the other hand, the engine is inserted and detachably installed from the end direction, the engine is inserted into and detachably attached to the refrigeration equipment frame in the same direction as the insertion direction of the refrigeration equipment frame, and the exhaust pipe of the engine is installed in the insertion direction. and extending in a direction perpendicular to the refrigeration equipment frame, penetrating the side wall of the refrigeration equipment frame, and connecting to a silencer attached to the container, and further dividing the exhaust pipe at the interference part between the exhaust pipe and the side wall. The divided exhaust pipes are connected by a joint pipe that is longer than the thickness of the side wall.

With this configuration, the drive unit including the engine can be freely attached to and detached from the refrigeration equipment frame.
In addition, the refrigeration system frame is detachable from the container, and the exhaust pipe and silencer of this engine can be attached and detached at the joint pipe. The unit can be easily attached and detached.

(Example) Fig. 1 is a plan view of the main parts of a refrigerated container having an exhaust system structure for an engine for refrigerated containers according to an embodiment of the present invention, and Fig. 2 shows an exhaust pipe included in this exhaust system structure. It is a perspective view of the joint pipe which connects with a silencer.

In FIGS. 1 and 2, 1 is a container in which frozen foods are stored, and 2 is a refrigeration equipment frame disposed in a recessed space formed at one end of the container 1. In FIG. The refrigeration system frame 2 includes a refrigeration system 3 having a refrigerator 4 for cooling the inside of the container 1, and a drive unit 7 having an engine 5 and a generator 6 for driving the refrigeration system 3. It is provided. The engine 5 and generator 6 are integrally configured to be detachably attached to the refrigeration system frame 2. Engine 5 exhaust pipe 8,1
0 is divided by the interference part of the side wall of the container 1, a flange 9 is provided at the end of the exhaust pipe 8 on the engine side, a flange 11 is provided at one end of the other exhaust pipe 10, and the other end is provided with a flange 9. The end portion is connected to a silencer 13 fixed to the container side pole 12.

14 is a joint pipe which is a feature of the present invention, and this joint pipe 14 is formed longer than the thickness of the side wall of the refrigeration equipment frame 3, and flanges 15 and 16 are provided at both ends of the joint pipe 14. There is. Collars 17 and 18 are fixed between the flanges 15 and 16. The exhaust pipe 8 and the exhaust pipe 10 are connected by a joint pipe 14. That is, flanges 9, 15
Gaskets 19 are sandwiched between the flanges 11 and 16, and the bolts 20 and nuts 21
flange 9,15 and flange 11,1
6 are fixed respectively. Further, the joint pipe 14 is arranged between the side plates 22, 22 of the refrigeration apparatus.

Figure 3 shows the container 1 and the refrigeration equipment frame 2.
2 is a perspective view showing the overall layout of the drive unit 7 and the drive unit 7. FIG. The drive unit 7 is set in a space 2a of the refrigeration system frame 2 which accommodates and fixes the refrigeration system 3. Next, the refrigeration system frame 2 including the set drive unit 7 is set in the space 1a of the container 1. In this manner, the refrigeration system frame 2 is set in the container 1, and thereafter the exhaust pipes 8, 10 of the engine 5 are connected to the silencer 13 by the joint pipe 14, as described above.

By configuring the refrigerated container in this way, in particular by dividing the exhaust pipes 8 and 10, connecting the divided exhaust pipes 8 and 10 with the joint pipe 14, and connecting the engine 5 and the silencer 13, The degree of freedom of the mounting structure of the silencer 13 is not impaired, and the refrigeration equipment frame 2 is attached to the container 1.
Furthermore, the drive units 7 can be easily attached to and detached from the refrigeration apparatus frame 2.

(Effects of the invention) As described above, according to the invention, the drive unit is configured to be detachable from the refrigeration equipment frame to which the refrigeration unit is attached, and the exhaust pipe is divided into this engine, and the divided exhaust By connecting the pipe with a joint pipe and connecting it to the silencer attached to the container, it is possible to drive the refrigeration equipment frame relative to the container and the refrigeration equipment frame without impairing the freedom of the silencer installation position. The unit can be easily attached and detached, and the workability of the above-mentioned attachment and detachment can be improved.
