Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a compressed air aftercooler device driven by a bonnet type engine, and in particular, a bonnet type air compressor which can be installed without any special modification to an existing bonnet type air compressor. It relates to the aftercooler device of the machine.

[0002]

[Prior art]

 Generally, a bonnet-type air compressor that has an air compressor driven by an engine installed inside the hood is installed in a narrow place when it is transported by vehicle to each work site or used for equipment. In order to be used, the outer dimensions of the bonnet must be reduced, and thus, waste space in the hood has been minimized. On the other hand, the air compressor referred to as the “standard type” is not designed to include so-called additional equipment such as an aftercooler, and should be equipped with additional equipment only when required by the customer. I have.

Conventionally, when an aftercooler device is incorporated in the above-mentioned “standard type” air compressor, specifically, as shown in FIG. 3, the aftercooler member C of the aftercooler device 1 is used. May be located in a gap (a) formed between the cooling fan F of the engine E and the radiator R or the oil cooler O, or the cooling air inlet of the bonnet B, that is, generally, Is located on the side opposite to the cooling fan F of the engine E, and is installed in a gap (b) generated between the compressor K main body and the outside air inlet BH provided on the side wall BW of the bonnet BW. .

[0004]

[Problems to be solved by the invention]

 When the aftercooler member C is disposed in the former gap portion (a), the cooling fan F of the engine E forcibly cools the aftercooler member C directly, so that efficient compressed air cooling is possible. . However, the space between the engine E and the radiator R or the oil cooler O (a) may be difficult to install due to the narrow space, and in such a case, the radiator R or the oil cooler O may be difficult to install. It is necessary to move the arrangement position of the oil cooler O in a direction away from the engine E to secure the installation gap. Further, when the aftercooler member C is mounted in such a gap portion (a), a special mounting member is required because the aftercooler member C must be mounted in a narrow gap, and the mounting work requires time and labor. I was Further, when the aftercooler member C is disposed in this gap portion (a), the piping route is from the tank T for storing the compressed air to the aftercooler member C, and is discharged to the outside on the opposite side. In order to provide a complicated long piping path in which piping is performed to the valve V, which is an outlet, it is necessary to prepare a specially processed long piping material P.

[0005] On the other hand, when the aftercooler member C is installed at the latter gap position (b), the aftercooler member C is mounted on the flow path of the outside air introduced into the bonnet B. Therefore, the compressed air of the aftercooler member C is supplied to the engine. The cooling is forcibly performed with the operation of the cooling fan F of E. However, even when the aftercooler member C is arranged in this gap portion (b), the arrangement position is the narrow space like the above-mentioned gap portion (a), and the aftercooler member C is placed in such a portion. If piping is to be performed after the arrangement, it may not be possible to install the aftercooler member C or the like in the standard bonnet B. In such a case, it may be necessary to prepare a new hood in which the length of the standard hood B is extended by the width required for the installation of the aftercooler member C.

Accordingly, the present invention has been made to solve the conventional problems when an aftercooler device is installed in such a standard hood-type air compressor, and its object is to solve the problem. However, the standard bonnet type air compressor has a standard bonnet-type air compressor in which the length of the bonnet is extended to prepare special mounting members and to arrange the aftercooler device. An object of the present invention is to provide a bonnet-type air compressor aftercooler device that does not require preparing a new bonnet separate from the bonnet.

[0007]

[Means for Solving the Problems]

 In order to solve such a problem, the aftercooler device of the bonnet type air compressor according to the present invention is a bonnet type air compressor in which an air compressor driven by an engine is installed in the hood. Mounting an aftercooler for cooling the compressed air discharged from the storage tank of the air compressor and an aftercooler storage section for storing the aftercooler outside the outside air introduction portion provided on the bonnet. This is a means for solving the problem.

The aftercooler device 1 for an air compressor shown in FIGS. 1 and 2 is provided for a hood-type air compressor in which a compressor K driven by an engine E is provided inside a bonnet B main body. In addition, it is provided on the side wall BW of the bonnet B, and is attached to a portion outside the inlet BH, which is a portion for introducing outside air. The tank T for storing the compressed air produced by the compressor K and the aftercooler member C of the aftercooler device 1 are connected by a pipe material P. The aftercooler member C is housed in the aftercooler storage section 20 and is screwed and fixed to the outside of the inlet BH of the bonnet B. The aftercooler member C accommodated in the aftercooler storage section 20 described in the present embodiment has a configuration in which two units are installed in parallel. However, the shape of the bonnet B and the capacity of the air compressor are different. It is needless to say that the number and shape can be increased or decreased in accordance with the number of pieces.

Here, details of such an aftercooler device 1 will be described. As shown in FIG. 2, an inlet BH for introducing outside air is formed in a side wall BW of a standard type bonnet B in which an air compressor is installed. A side plate having a louver is mounted in a state in which the inlet BH is to be loaded. When attaching the aftercooler storage section 20 for storing the aftercooler member C to the bonnet B, first remove this side plate from the side wall BW of the bonnet B. An outside air inlet BH is formed in the side wall BW of the bonnet B from which the side plate has been removed, and the perforated plates 10L and 10R engaged with the shape of the inlet BH are provided with sound insulation and aftercooler. It is screwed and fixed for the guard of the member C. In addition, perforated holes 13 for screwing and fixing an aftercooler storage portion 20 to be described later are formed all around the peripheries of the perforated plates 10L and 10R.

As shown in FIG. 2, the aftercooler storage section 20 has a frame shape having both openings including an upper cover member 11, a lower cover member 12, and left and right bracket members 15 and 16. One of the two frame-shaped openings is screwed and fixed to the side wall BW of the bonnet B to which the above-described perforated plates 10L and 10R are fixed, and the other opening is provided with a plurality of louvers Ru (outside air introduction). The side plate BW1 forming the mouth is screwed on to form a box shape. A flange 21 is formed on the outer edge of the box-shaped aftercooler storage portion 20 over the entire circumference, and an appropriate portion of the flange 21 is screwed to a side wall BW of the hood B to be fixed. A hole 21a is formed. A central bracket member 17 for internally dividing the box-shaped aftercooler storage section 20 is screwed and fixed to a substantially central portion of the upper cover member 11 and the lower cover member 12, thereby reinforcing the strength. .

A base member 18 to which a vibration absorbing material 18a made of an elastic body is attached is fixed to the inside of each of the top side of the lower cover member 12 and the bottom side of the upper cover member 11. The aftercooler member C is placed on the base member 18 on the top portion of the upper cover member 11, and the aftercooler member C is sandwiched by the base member 18 on the bottom side of the upper cover member 11 and stored in the aftercooler storage portion 20. I have. When each of the aftercooler members C is stored in the aftercooler storage section 20, the aftercooler members C are fixed to the upper cover member 11 and the lower cover member 12 by the fixing bracket 19.

After the aftercooler member C is fixed in the aftercooler storage section 20, a soundproofing material or a vibration absorbing material (not shown) is attached to the inside of the frame, so that the engine generated in the bonnet B is formed. It is possible to block the absorption of noise from E and the compressor K and the propagation outside the bonnet B. Further, if a dust-proof filter or the like is arranged in the gap between the perforated plates 10L, 10R and the aftercooler member C, it can be introduced. Dust and the like contained in the outside air can be prevented from entering the bonnet B.

Regarding the method of attaching the aftercooler storage section 20 to the bonnet B main body, in the present embodiment, a method in which the flange 21 of the outer edge of the aftercooler storage section 20 is directly screwed to the bonnet B main body. As described above, other than this method, any method may be used as long as the after-cooler member C can be easily inspected.

The piping material P of the after-cooler member C fixed to the side wall BW of the bonnet B and the tank T for storing the compressed air made of the compressor K as described above is formed of the after-cooler member C to be attached. Although it differs depending on the number of units, it may be performed using a pipe material P appropriately shaped.

[Effect of the invention]

 According to the aftercooler device of the hood type air compressor of the present invention, the following effects can be obtained.

[0017] When an after-cooler device is added to the conventional standard hood-type air compressor, special mounting members in the hood are prepared, and the length of the hood is increased. There is no need to prepare a new hood. That is, it is possible to attach the aftercooler without manufacturing a standard bonnet by providing extra space so that the aftercooler can be added from the beginning. Further, since the aftercooler device can be attached and detached without almost disassembling the conventional hood type air compressor, the attachment and detachment work can be performed in a short time. In addition, there is no need to significantly change the piping inside the bonnet, and since the location of the standard compressed air discharge valve that is placed on the bonnet from the beginning of manufacture is unchanged, the already installed air compressor can be used. Even after that, the aftercooler can be easily installed.
