Abstract

PURPOSE:To prevent an overturn of a dump car on the inclined ground by providing a detecting body that detects the absolute angle of inclination of the loading platform relative to the ground CONSTITUTION:A loading platform 21 is supported around a supporting pin 23, which is installed at near the after end of a car body frame 22, in such a manner that the platform can be rotated in the vertical plane. An expansion- and-contraction body 24 is inserted between this loading platform 21 and the car body frame 22. By expanding or contracting this expansion-and-contraction body 24, the loading platform is dumped. A detecting body, which detects an absolute angle of inclination of the loading platform relative to the ground, is installed in the over 29. The output signal of this detecting body is fed back in correspondence to the expanding or contracting movement of the expansion- and-contraction body 24.

としたものである。(d) Means for Solving the Problems Therefore, the present invention provides a method for interposing an extensible body between the loading platform and the vehicle body frame, and tilting the loading platform by the expansion and contraction movement of the expanding extensible body. In a car dump device, a deviation detector is installed to detect the absolute slope of the loading platform with respect to the ground;
The basic configuration is that the predetermined output signal of this sensing body is hacked with respect to the telescoping operation of the telescoping body, and in this configuration, the telescoping body is a hydraulic cylinder and the sensing body is a pendulum type. The additional configuration is that it is a sensor.

Then, this loading platform 21 and the vehicle body frame 2
An appropriate telescopic body 24 is interposed between the two, and by making the telescopic body 24 expand and contract, the loading platform 21 can be forcibly dumped.

ところで、この発明は、以」二のような運搬車のダンプ
装置において１次のように構成したものである。By the way, the present invention is a dump device for a transport vehicle as described below, which is configured as follows.

すなわち、荷台２１の地面に対する絶対的傾斜度を検知

を伸縮体２４の伸縮動作に対してフィードバックさせた
ものである。That is, a sensing body 25 is provided to detect the absolute degree of inclination of the loading platform 21 with respect to the ground, and a predetermined output signal of this sensing body 25 is fed back to the expansion/contraction operation of the expansion/contraction body 24.

なお、伸縮体２４がこのフィードバック信号を受ければ
、所定の動作（例えば、伸縮動作をその位置で保持）を
するように設定しておくのはもちろんである。Note that it goes without saying that the expandable body 24 is set to perform a predetermined action (for example, hold the telescopic action at that position) when it receives this feedback signal.

のようなものが適する。The sensing body 25 detects the absolute inclination of the loading platform 21 with respect to the ground (
Since the device detects the combination of the inclination of the loading platform 21 and the inclination of the vehicle body, any structure may be used as long as it meets the purpose, but for example, a first-order sensor may be used. things are suitable.

よって制御するのである。As shown in FIG. 2, 1. The control circuit for the detection body 25 when a hydraulic cylinder is used as the telescoping body 24 is as follows. A directional control valve 32 is provided with a valve 32 for switching the direction of pressure oil by means of 31, and a directional control valve 32 is provided with a valve 32 for switching the direction of the pressure oil.
31 is controlled by -1- stomach sui-nochi 33 and lowering switch 3-i.

停止させてしまうのである。If the loading platform 21 deviates by a predetermined angle ('ITi&'11), a predetermined output signal is output from the detection body 25, and this is sent to the direction switching valve 32 as appropriate. Even if the -30 and -31 are activated, they are cut off and the hydraulic cylinder is stopped at that position.

It is sufficient to connect the closing contact 28h in series with both switches 33 and 34.

都合２ケが必要になる。By the way, the above-mentioned side number is for carrying the cargo platform 21 backwards and dumping it, or it can also be dumped to the side by means of a transport vehicle. There is also a so-called two-axis dump truck, but it is easy to think of applying the above to a dump truck with a measuring direction in addition to the rear. In this case, the detection body 25 has two types, one for the rear and one for the side. It becomes necessary.

A detector 25 for detecting the absolute inclination of the loading platform 21 with respect to the ground is provided, and a predetermined output signal of the sensing component 25 is transmitted to the loading platform 2.
1, the loading platform 21 does not extend beyond a dangerous certain angle even if the vehicle body is tilted in advance during dumping. Therefore, accidents such as falls caused by careless dumping on slopes, etc. are prevented, and safety is improved.
