Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a soundproof/waterproof structure for a forklift, and particularly to a soundproof/waterproof structure for closing the gap between a radiator cover and a balance weight.

[Conventional technology]

In a conventional forklift, for example, as shown in FIG. 4, a radiator (not shown) is disposed between the rear head guard pillars 1, and a radiator cover 2 is placed between the rear head guard pillars 1 to cover the upper part of the radiator (not shown). is fixed. In addition, there is a radiator and radiator cover 2 at the rear of the vehicle.
A balance weight 3 is installed adjacent to this.

[Problem that the idea aims to solve]

In such conventional forklifts,
A gap 4 is formed between the radiator cover 2 and the balance weight 3. Therefore, noise such as the engine sound inside the vehicle body leaks through this gap 4, causing discomfort to the driver, and there is also a risk that water from washing the car or rainwater may enter the vehicle body and adversely affect internal parts. There was a problem that there was. Furthermore, this gap 4
Due to variations in the manufacturing of parts, the parts were not aligned and the appearance was impaired. Therefore, the purpose of this invention is not only to have a simple structure but also to have soundproofing and waterproofing functions.
To provide a soundproof and waterproof structure for a forklift that can prevent water from entering the driver's seat side.

[Means to solve the problem]

To achieve the above object, the present invention provides a soundproof and waterproof structure for a forklift in which a balance weight is disposed adjacent to the rear of a radiator cover, and a flange integrally formed on the rear side edge of the radiator cover. and a seal member that is attached to the flange and comes into elastic close contact with the balance weight, and the seal member cooperates with the balance weight to define a drainage groove between the balance weight and the balance weight. It is characterized in that it has a shape and is attached to the flange.

[Effect]

According to the above-described soundproof and waterproof structure of the present invention, the sealing member closes the gap between the balance weight and the radiator cover, thereby achieving soundproofing and waterproofing. Furthermore, the sealing member not only prevents rainwater etc. from entering the radiator, but also cooperates with the balance weight to form a drainage groove, so that rainwater etc. is guided and drained by the drainage groove. Therefore, rainwater or the like does not run down the radiator cover and enter the driver's seat side, that is, the cabin space.

【Example】

Hereinafter, preferred embodiments of the soundproof and waterproof structure for a forklift according to the present invention will be described in detail with reference to the drawings. Note that the same reference numerals will be used to describe the same or corresponding parts as in the conventional configuration. FIG. 1 shows a portion to which the present invention is applied in a partial cross-sectional view along the front and back direction of a forklift. As shown in the figure, a downward flange 6 is integrally molded over the entire length of the radiator cover 5 attached between the rear head guard pillars 1 on the rear side edge of the balance weight 3 side. A sealing member 7 made of an elastic material is fitted into the flange 6 and fixed to the flange 6 by suitable means such as adhesive. When no load is applied to the sealing member 7,
It has a cross-sectional shape shown by a dashed line in FIG. When the radiator cover 5 to which the seal member 7 is attached is attached to a predetermined position after the balance weight 3 is installed, the side surface of the seal member 7 comes into contact with the upper front surface of the balance weight 3, causing elastic deformation toward the front of the vehicle body. It is designed to fit tightly with an appropriate pressing force. As a result, the gap 4 between the radiator cover 5 and the balance weight 3
is sealed. Further, since the sealing member 7 is formed in a shape to define a drainage groove 8 between it and the balance weight 3, this drainage groove 8 acts as a rain gutter, and the water on the upper surface of the balance weight 3 flows into the radiator. It is possible to prevent the vehicle from exceeding the cover 5 and entering the driver's seat side, that is, the cabin space. Next, the radiator cover 5 in this embodiment
The mounting device will be explained below. As clearly shown in FIG. 2, each end of the radiator cover 5 is placed on a bracket 10 welded to the inner side surface of the head guard pillar 1, and a U-shaped plate is attached to the underside of the bracket 10. The mounting bolts 15 extending through the holes 13 and 14 of the radiator cover 5 and the bracket 10 are screwed into nuts 12 disposed through the radiator cover 5 and the bracket 10 . This mounting bolt 15 has a bolt head 16
It is configured so that it can be turned by hand.
The radiator cover 5 can be easily attached and detached. Further, in order to prevent the attachment bolt 15 from being lost, it is preferable to provide a retainer made of a flat washer 18, an E-ring 19, etc. on the shaft portion 17 of the attachment bolt 15. In the past, as will be understood by referring to FIG. 4, the radiator cover 2 is bolted so that it is difficult to remove, and the water inlet 20 of the radiator passes through the through hole 21 of the radiator cover 2 and is exposed to the outside. However, there were disadvantages such as water intrusion and engine sound leaking from this through hole 21, but by making the radiator cover 5 easy to attach and detach as shown in the mounting device shown in Fig. 2, soundproofing can be achieved. For waterproofing, it is possible to cover the water inlet 20 of the radiator 22 with the radiator cover 5 (FIG. 1). Further, as understood from FIG. 3, gaps 25 are also formed between each of the rear head guard pillars 1 and the balance weight 3. This gap 2
The noise leaking from the rear head guard pillar 1 is transmitted almost horizontally and does not reach the driver's ears, and the intrusion of rainwater is also minimal, so it is not necessarily necessary to close it, but the inside of the rear head guard pillar 1 A Z-shaped steel 26 is welded to the side surface of the Z-shaped steel 26, and a sealing member 28 similar to the sealing member 7 shown in FIG. Thus, the space between the balance weight 3 and the rear head guard pillar 1 may be sealed.

[Effect of the idea]

As described above, according to the present invention, since the gap between the radiator cover and the balance weight is sealed by the sealing member, the noise in the driver's ears is reduced and the driving environment is improved, and rainwater etc. can enter the vehicle body. This not only protects internal electrical components from corrosion, but also extends the life of the forklift itself, which is often exposed to the elements. Moreover, since the sealing member cooperates with the balance weight to form a drainage groove, rainwater, etc. is guided and drained by the drainage groove, so that it flows through the radiator cover and reaches the driver's seat side, that is, the cabin space. This prevents water from entering into the footwells of drivers seated in driver's seats with head guards, thereby providing a comfortable working environment for the drivers. Further, by eliminating the gap, the appearance can be improved, and the flange formed for attaching the seal member improves the rigidity of the radiator cover.
