Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a lamp protection device, and is suitable for vehicle lamps installed on plows such as snow removal dozers, two-way dozers, or wheel loaders. Concerning the protection of

(Prior art) Conventionally, vehicle width lights have been installed on the tops of both ends of plows such as snow removal dozers, and these vehicle width lights have lamps fixed to the tops of both ends of the plow. The lamp was surrounded by a lamp guard, and several guard rods were attached to the front of the lamp guard, and the lamp was protected by the lamp guard and the guard rods.

(Problem to be solved by the invention) In the above-mentioned conventional lamp protection structure, when snow, etc. climbs over the top of the plow during snow removal work, the snow, etc. enters into the lamp guard between the guard rods and protects the lamp. There was a problem in that the lamp was damaged due to excessive pressure.

The present invention has been developed in view of the above-mentioned problems, and an object of the present invention is to provide a lamp protection device that prevents damage to the lamp.

[Structure of the idea]

(Means for Solving the Problems) The present invention provides a lighting device in which a lamp 6 is surrounded by a lamp guard 7 for a construction machinery vehicle, and the lamp guard 7 is folded into openings on the front and rear surfaces, and at least the front surface is resistant. A protective plate 11 having scratch resistance and translucency, and the lamp guard 7
A substantially L-shaped holding member 17 that is engaged with the front protection plate 11 and the rear protection plate 11 from multiple locations that do not shift on the circumferential surface of the
A plurality of mounting rods 14 are inserted through the front and rear protection plates 11 through the front and rear holding members 17 at a plurality of locations, and the ends of the plurality of mounting rods 14 are screwed together and protected via the holding members 17. plate 1
1 into the opening of the lamp guard 7.
A lamp protection device having:

(Function) The present invention has a lamp guard 7 surrounding the lamp 6.
At least the front surface of the lamp guard is closed by a protection plate 11 having scratch resistance and light transmission properties to prevent snow and the like from entering into the lamp guard.

(Example) Next, an example of the present invention will be described with reference to the drawings.

Fig. 3 shows a wheel type loader as a construction machinery vehicle, which is attached to the tip of a lift arm 1 that is moved up and down by a lift cylinder (not shown), and is used to move left and right, such as a slide ring plow, and to move left and right. A plow 2 whose ends are angle-adjustable in the longitudinal direction is installed, and side lamps 5 as lighting equipment are provided at the upper portions of both ends of the plow 2.

As shown in FIGS. 1 and 2, the sidemarker lights 5 have a lamp 6, and the lamp 6 is surrounded by a lamp guard 7. As shown in FIGS. Note that this lamp 6 includes a lamp body, a light source disposed inside the lamp body,
It has a reflecting mirror disposed opposite to this light source, and a lens is provided on the front surface of the lamp body. and,
The lamp guard 7 has its front and rear sides open, has a flat fixing part 8 fixed to the top of both ends of the plow 2 at the bottom, and has a plurality of guard rods 9 attached to the front side along the vertical direction. .

A protection plate 11 is attached to the front and rear surfaces of the lamp guard 7. The protective plate 11 is made of scratch-resistant and translucent material such as polycarbonate or methacrylic resin, or bulletproof glass, and has almost the same shape as the opening surface of the lamp guard 7. A hole 12 is provided in each case. A pair of protection plates 11 are arranged on the front and rear surfaces of the lamp guard 7, and each mounting hole 1 of one of the protection plates 11 is
2, insert the mounting rods 14 having threaded portions 13 at both ends, and penetrate through the mounting holes 12 facing each other in the other protection plate 11.
A threaded portion 13 is protruded from the side surface of each of the mounting rods 14, and an elastic rubber 15 is attached to the threaded portion 13 of each mounting rod 14. A nut 19 is screwed together via a washer 18 and a retaining member 17 having a retaining piece 16 for positioning and retaining the lamp guard 7, and is tightened and fixed from both sides of the protective plate 11 to secure the front and rear surfaces of the lamp guard 7 with the protective plate 11. Obstruction.

Then, attach the protective plates 11 to the front and rear surfaces of the lamp guard 7 as described above, and then attach the protective plates 11 to the lamp guard 7.
When the front and rear sides of the lamp guard 7 are blocked by the side lights 5 on the plow 2, if snow, etc., gets over the top of the plow 2 during snow removal work, the protection plate 11 blocks the front and rear sides of the lamp guard 7, so the snow, etc. is prevented from entering the lamp guard 7, and the lamp 6 within the lamp guard 7 is protected.

[Effect of idea]

According to the present invention, at least the front side is equipped with a scratch-resistant and translucent protection plate in the front and rear openings of the lamp guard, so that, for example, snow can be forced into the lamp guard from the front during snow removal work. The lamp inside the lamp guard can be reliably protected. In addition, since the approximately L-shaped holding member engaged with the circumferential surface of the lamp guard positions and holds the front and rear protection plates, there is no need to take any measures such as welding nuts to the lamp guard. You can easily install the protection plate without adding anything. Furthermore, the lighting equipment installed in plows, etc. of construction machinery vehicles related to the present invention is subject to harsh conditions (such as severe vibrations and direct pressure from snow, dirt, etc.) that are incomparable to headlamps of passenger cars. Although the protective plate is used under severe conditions), the present invention allows the protective plate to be securely fixed by the approximately L-shaped holding member, the mounting rod, and the nut, and there is no risk of the protective plate falling off.
