Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a shroud for guiding air installed on the back of a heat exchanger for cooling engine cooling water used in construction machinery, industrial machinery, etc. This invention relates to a wire net mounting structure that prevents danger by closing an opening through which a rotating fan is exposed.

[Prior art]

Conventionally, a large heat exchanger core for construction machinery or industrial machinery has a shroud for guiding air and a fan installed in the shroud. The rear opening of the shroud was then closed off with a suitable wire net to prevent the risk of touching the rotating part of the fan.

However, this type of heat exchanger often collides with various foreign objects and deforms the wire, making it necessary to replace it. In such cases, conventional shrouds are difficult to install and remove.
Further, the wire nets had to be designed separately for each type of heat exchanger, which was troublesome.

[Means for solving problems]

Therefore, the object of the present invention is to provide a wire net that is easy to replace and has compatibility, and its configuration is as follows.

That is, it has a plurality of wires 1 each having a predetermined length. Rubber bushes 3 are connected to both ends of the wire 1, with their axes perpendicular to the base of the wire 1. This rubber bush 3 has an annular groove 2 formed on its outer periphery to prevent it from coming off. Further, a plurality of holes 5 are bored in the shroud 4 along the opening of the shroud 4. Then, each of the rubber bushes 3 is fitted into the hole 5, and the edge of the hole is in the annular groove 2.
It is attached to.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a longitudinal sectional view of the main part of the present wire net mounting structure. FIG. 2 is a plan view of the same, and FIG. 3 shows an example of the arrangement of wire nets attached to the back surface of the heat exchanger. In this embodiment, a heat exchanger core is formed between a pair of vertically spaced tanks 7, 7,
A peripheral portion of the shroud 4 is attached to the back surface of the core. This structure is attached to the edge of the opening 8 formed in the center of the shroud 4. That is, a large number of holes 5 are formed along the edge of the opening 8, and the rubber bushings 3 of the respective wire elements are fitted into the holes 5. As shown in FIG. 1, this wire net consists of a wire 1 and rubber bushings 3 attached to both ends of the wire. The wire 1 has a certain degree of rigidity and elasticity, and both ends thereof are bent at right angles, and a T-shaped part is formed at the tip. Next, rubber button 3
The entire body is formed into a stepped bullet shape, and an annular groove 2 for preventing slippage is formed on the outer periphery of the central portion.
Further, the rear end surface of the rubber bush 3 is provided with a cut 6 as shown in FIG. 2, and the lower part of the cut 6 is formed in the shape of a groove. Then, by fitting the end of the wire 1 into the wire 1 and rotating the rubber bush 3 by 90 degrees, a locked state as shown in FIG. 1 is established. Then, the end of the wire 1 and the rubber bush 3 are fixed with adhesive 9 to form a wire element. Then, the rubber bush 3 of such an element is fitted onto the periphery of the opening 8 as shown in FIGS. 1 and 3. Then, the annular groove 2 of the rubber bush 3 is locked and held in the hole 5. In this way, the present structure is completed by attaching a large number of wire elements as shown in FIG. Thereby, the rotating part of the fan housed in the shroud 4 can be protected and danger can be prevented.

Next, FIG. 4 shows a second embodiment of the present invention, in which each wire net element is arranged so as to partially intersect with each other as shown in the figure. In this case, the heights of one wire element and the other wire element crossing it may be changed.

[Effect of idea]

The mounting structure of the present invention has the above configuration and has the following effects.

This structure has rubber bushings 3 at both ends of the wire 1.
The element has a very simple structure in which the rubber button 3 can be attached to the opening 8
The installation of the wire net can be completed by fitting it into the hole 5 on the periphery, so it is easy to manufacture and can be provided at low cost. It is also relatively easy to install, has excellent compatibility, and can be commonly installed on various shrouds. . Furthermore, since the rubber bush 3 is provided, it has vibration resistance and can prevent the wire net itself from becoming a source of noise. Partial repair and replacement can also be easily performed.
