Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a window glass of a simple driver's cab provided at the front and rear of the vehicle body in a locomotive used in a steelworks etc. and towing a high-temperature material carrier, and This invention relates to a locomotive heat shield installed to protect molded rubber for attaching glass.

[Background of the invention]

A heat shielding device provided in a conventional locomotive having the simple cab (for example, Japanese Utility Model Application Publication No. 54-42208) will be explained with reference to FIGS. 1 and 2. As shown in FIGS. 1 and 2, a mounting bracket 8 with an elongated hole is provided on the front of the simple cab 1 provided at the front and rear of the locomotive body, and a latch 5 and a mounting bracket 9 are attached to the mounting bracket 8. The heat shield plate 4 is attached using pins 10 and split pins 11. When protection of the window glass 2 and the window glass attachment mold rubber 3 is not required during normal operation, the heat shield plate 4 is lowered and hung on the lower bracket 6 as shown by the solid line in FIG. When towing a high-temperature material carrier, it is necessary to protect the window glass 2 and mold rubber 3, so remove the heat shield plate 4 from the lower bracket 6, rotate it, and attach the upper bracket to the top of the window glass 2. Hang on gold 7, window glass 2
The structure was such that the molded rubber 3 was protected from the radiant heat of the high-temperature transport vehicle. However, in such a configuration, since a steel plate is used for the heat shield plate 4, the heat shield plate 4 itself is heavy and requires a great deal of force to operate, and if your hand accidentally slips during operation, it can cause serious damage. The disadvantage was that there was a risk of injury. In addition, in the above configuration, when rotating the heat shield plate 4, it is necessary to go outside the simple operator's cabin 1 and perform the work, which is complicated during rain and at night. The drawback was that there was a high possibility of accidents occurring.

[Purpose of the invention]

An object of the present invention is to provide a heat insulating device in which the moving operation of the heat insulating plate is easy and the safety is high.

[Summary of the invention]

The present invention provides a heat insulating plate that covers the front surface of a window of a simple driver's cab installed at the front of the vehicle body, and a heat insulating plate that is supported at a position corresponding to the window at the front of the simple driver's cab and is movable in the width direction of the vehicle body. The present invention is characterized in that it comprises a supporting means for moving the heat shield plate, and a moving means for moving the heat shield plate.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. As shown in FIGS. 3 and 4, a rotatable roller 15 and a handle for opening and closing are attached to a roller rail 12 attached to the upper part of the window in front of the simple operator's cab 1 and a heat shield guide 13 provided to the lower part of the window. 14, etc., is fitted so as to be movable in the horizontal direction, that is, in the width direction of the vehicle body. Then, if necessary, the heat shield plate 2
0 is opened and closed to protect the window glass 2 and the rubber mold 3 for attaching the window glass from the radiant heat of the high-temperature transport vehicle. In addition, in order to fix the heat shield plate 20 in a predetermined position, pin insertion metal fittings 18 and 19 are attached to the heat insulation plate guide 13 and the heat insulation plate 20, and the pin insertion metal fittings 18 and 19 are attached to the heat insulation plate guide 13 and the heat insulation plate 20.
, the pin 16 is attached to the heat shield plate 20 with a chain 17.
By inserting the heat shield plate 20, the heat shield plate 20 is fixed in a predetermined position. According to such a configuration, the heat shield plate 2
Since it is configured to move 0 in the horizontal direction, it can be operated with a small amount of force compared to conventional configurations, simplifying the work and saving labor. Furthermore, there is no danger of the hand slipping and causing an accident during work, unlike in the past, and the safety of the worker can be ensured.

In addition, although the heat shield plates 20 are provided as a pair in the above embodiment, the present invention is not limited to this.

By the way, in the above embodiment, the heat shield plate 2
0 must be moved outside the simple operator's cabin 1, which is a complicated operation during rain and at night, and also poses a safety problem.
Therefore, other embodiments according to the present invention, which will be described later, take the above points into consideration.

The configuration of the other embodiment shown in FIGS. 5 and 6 is that a pair of left and right heat insulating plates 20 are supported movably in the horizontal direction by roller rails 12 and heat insulating plate guides 4 via rollers 15. are the same.
However, in this configuration, first, the link mounting pins 25, 26, washers 27,
28. Attach the link 21 with the split pin 30. On the other hand, in order to operate the link 21 from inside the simple operator's cab 1, a link operation is provided in which a guide hole 22 is provided on the front surface of the simple operator's cab 1, and a handle 24 that passes through the guide hole 22 and is bendable is provided. A simple mechanism in which the pin 23 is attached to the link 21 with a washer 29 and a split pin 30 allows the link operating pin 23 to be inserted into the guide hole 2 through the handle 16.
The left and right heat insulating plates 2 are opened and closed at the same time via links 21. Further, in order to fix the heat shield plate 2 in a predetermined position, handle fixing spring fittings 31 are provided above and below the guide hole 22, and by bending and fitting the handle 16 into these spring fittings, the handle 16 is securely fixed.

Next, the other embodiments shown in FIGS. 7 and 8 are different from the other embodiments in the means for vertically moving the link operating pin 23. That is, a wire rope 32 having both ends attached to the link operating pin 23 and forming a ring is rotatably attached to the inside of the simple operator's cab 1 by means of rollers 33. Therefore, when the wire rope 32 is pulled, the link operating pin 23 moves up and down, and the left and right heat shields 2
0 can be opened and closed at the same time. Note that according to this configuration,
Since the wire ropes 32 are provided at both ends of the simple operator's cab 1, compared to the other embodiments, the operation can be performed without having to enter the simple operator's cab 1 each time the heat shield 20 is opened or closed. There is.

As described above, according to the other embodiments shown in FIGS. 5 to 8, there is no need to go outside the simple operator's cabin 1 when opening and closing the heat shield 20, and work is simplified and safer during rain or at night. can be improved. Moreover, opening and closing operations can be performed by simply moving the handle 24 up and down or pulling the wire rope 32.

Next, in the structure of another embodiment shown in FIGS. 9 and 10, a wire rope 33' is attached to the link operating pin 23 in the same manner as in the embodiment shown in FIG. As shown in the figure, the wire rope 33' is provided inside the simple operator's cab 1 so as to be able to turn via a roller 32', and the wire rope 33' is pulled by a motor 34 to open and close the heat shield plate 20. .

Further, in other embodiments shown in FIGS. 11 and 12, the link operating pin 23 is moved up and down by a hydraulic or pneumatic cylinder 35 to open and close the heat shield plate 20. In addition, in the embodiments shown in FIGS. 9 to 12,
The support structure for the heat shield plate 20 is the same as in the other embodiments.

According to the configuration in which the heat shield plate 20 is moved by the other driving device, that is, the motor 34 and the hydraulic or pneumatic cylinder 35, the worker does not have to move the heat shield plate 20 directly, so that labor saving in the work is achieved. At the same time, there is no fear of accidents occurring, and safety can be improved.

〔Effect of the invention〕

As explained above, according to the present invention, the operation of moving the heat shield is simple and easy, and the heat shield does not move carelessly during operation, thereby improving safety.
