Description

[Detailed description of the invention] "Industrial application field" This invention relates to a guidance device for safely guiding a dump truck loaded with earth and sand to a loading position during leveling or reclamation work of earth and sand using a bulltozer. It is.

``Problems to be solved by conventional techniques and ideas'' In general, when leveling or reclamation work using a bulltozer, it is desirable to dump the earth and sand loaded in a dump truck into a position suitable for the work using the bulltozer. It is necessary to guide the dump truck so that its loading port accurately reaches the position where the soil is to be dumped.

In the past, specially appointed guides used flags and whistles to guide dump trucks to dump soil. As guidance work is carried out continuously at many sites, there are many accidents such as accidental getting caught in vehicles or thrown earth and sand, which poses safety issues, and hiring specialized guidance personnel increases labor costs accordingly. Therefore, construction economic problems arose.

"Means for solving the problem" This invention aims to solve the above-mentioned conventional problem.
This eliminates the need for guides by using a bulltozer and its driver waiting at the earth and sand dumping position.Indication poles that can be tilted up and down are installed on both sides of the bulltozer, and these are placed in the bulltozer operator's cab to indicate the earth and sand dropping position. This paper proposes a guidance device that can be operated by a driver who has experience in driving and can safely guide a dump truck.

``Embodiment'' Hereinafter, an embodiment of this invention shown in the drawings will be described. Indicator poles 2 for indicating the earth and sand dumping position are attached to both sides of a bulltozer 1 so that they can be raised and raised from horizontally horizontally to vertically.

The marking pole 2 has its base end fixed to a rotating shaft 4 supported by an angle-shaped mounting base 3 fixed to the bulltozer 1 with bolts, etc., and by rotating the rotating shaft 4 forward and backward by a motor 5. It is designed to move up and down.

This indicator pole 2 uses a telescopic tube made by slidably fitting tubes of different diameters, and is configured so that its length can be adjusted according to the drop position. A flashing light 6 and a flag 7 are attached to the.

The mounting base 3 is provided with a V-shaped supporting metal fitting 8 that supports the marking pole 2 when it is in the horizontal and vertical positions.

The motor 5 is electrically wired to an operating device 9 such as an operating switch installed in the driver's cab of the bulltozer 1 so that it can be operated remotely. The pole 2 can be raised and lowered.

Note that the marking pole 2 may be provided with an object approach sensor 10 that detects the approach of an object so that when a dump truck approaches, it is detected and an alarm is automatically sounded.

"Operation of the invention" First, the bulltozer 1 is moved to the vicinity of the earth and sand dumping position, and the driver lowers the indicator pole 2 horizontally in the driver's cab and extends it appropriately, and adjusts it to the dumping position while operating the bulltozer 1. The driver of the bulltozer guides the dump truck while monitoring the movement of the dump truck, aiming at this marking pole 2.During the day, the driver of the dump truck watches the marking pole or its flag, and at night, the driver of the bulltozer guides the dump truck by observing the marking pole or its flag. 2 or operate the dump truck while looking at the flashing light 6.

In this way, when the dump truck reaches the dumping position indicated by the marking pole 2, the bulltozer driver who is monitoring the bulltozer will signal to stop using a whistle, horn, light, etc., or the driver will use a sensor to detect the approach of the dump truck. automatically detects the situation and notifies you of the stoppage with an alarm buzzer, etc.

As a result, the driver of the dump truck can dump the cargo bed and dump the loaded soil safely and reliably to the dumping position, eliminating the hassle of driving while paying attention to the safety of the guidance worker as in the past. It becomes possible to eliminate the problem.

"Effects of the invention" As described above, according to this invention, the marking poles are pivotally mounted on both sides of the leveling bulltozer so that they can be lifted up and down from the horizontal to the vertical direction by the driving means, and the operating device of the driving means is connected to the leveling bulltozer. The leveling bulltozer is installed in the operator's cab of the bulltozer, so the driver can use the leveling bulltozer, which is always on standby near the earth and sand dumping position, and the driver who can empirically determine the appropriate earth and sand dumping position. It is possible to safely and reliably guide a dump truck and drop earth and sand without the need for a separate guidance worker by sequentially setting the marking poles to the dropping position by operating the bulltozer in the operator's cabin. It is easy to install and has low installation costs, and it can save labor while guiding work, improve safety, reduce construction costs, and streamline work.

Further, since the marking pole can be held in a vertical position when not in use, there is no problem with normal running of the bulltozer.
