Fig. 4 is the A-A cutaway view of Fig. 2 in the utility model.

Among the figure: 1, have the stationary contact piece 2 of contact, the movable contact piece 3 that has the contact, pressing plate 4, spring 5, base plate 6, moving contact 7, break back contact 8, electro-optical tubes 9, swing component 10, light source 11, square casing 12, rotating shaft 13, support

[specific embodiment]

Below in conjunction with accompanying drawing the utility model is described further:

As shown in Figure 1: the utility model is a kind of dumping car warning device, it comprises power supply, annunciator, plays bucket alarm switch, inclination alarm switch, lead, rise after bucket alarm switch and the parallel connection of inclination alarm switch again and power supply, the annunciator formation C/LOOP of connecting successively, described bucket alarm switch is installed on the wagon box support, and described inclination alarm switch is vertically mounted on the dumping car.

As shown in Figure 2: play the bucket alarm switch by base plate 5, spring 4, the stationary contact piece 1 that has the contact, the movable contact piece 2 that has the contact is formed, spring 4 one ends are fixedly mounted on the base plate 5, the other end is fixed on the movable contact piece 2, stationary contact piece 1 correspondence is positioned at movable contact piece 2 tops, stationary contact piece 1 contact is connected by lead with annunciator, annunciator is connected with positive source by lead, movable contact piece 2 contacts are connected by lead with power cathode, the wagon box bottom is equipped with pressing plate 3, the position that presses mutually with movable contact piece 2 one ends when pressing plate 3 correspondences are located at dumping car and do not play wagon box, when dumping car wagon box during not by jack-up, the pressing plate 3 of car bottom just is pressed in an end of movable contact piece 2, make moving contact and break back contact be in released state, whole warning device is in off-position.

As shown in Figure 3 and Figure 4: the inclination alarm switch comprises square casing 11, light source 10, swing component 9, electro-optical tubes 8, have light hole on the symmetric position on two planes of symmetry of square casing 11, light source 10 is installed in the outside of one of them plane of symmetry and the light hole correspondence position on this face, electro-optical tubes 8 is installed in the outside of another plane of symmetry and the light hole correspondence position on this face, one of them pin of electro-optical tubes 8 is electrically connected with annunciator, another pin is electrically connected with power supply, the inside face at square casing 11 tops is installed with support 13, rotating shaft 12 is installed on the support 13, swing component 9 one ends are enclosed within the rotating shaft 12 and form revolute pair with rotating shaft 12, rotating shaft 12 is parallel to the line of centers of two light holes, and swing component 9 is between the line of centers of two light holes.

When chaufeur was unloaded automatically, wagon box was by jack-up, and the pressing plate 3 that is installed on the car bottom loses the effect to movable contact piece 2, because the effect of spring 4 makes movable contact piece 2 contact with stationary contact piece 1, and then connects warning device, realizes warning; After unloading is finished, when driver's operation falls to the state of unloading preceding with wagon box, pressing plate 3 is depressed movable contact piece 2, movable contact piece 2 is separated with stationary contact piece 1, and then making the warning device outage, warning device stops to report to the police, and so just can avoid because the carelessness of chaufeur, after unsnatching goods, forget wagon box to be fallen or do not drop down onto the state before the unloading and be in half top state and accidents such as the extension building that occurs or aerial cable.In addition when the car body run-off the straight, swing component 9 is under the effect of gravity, depart from original position, the light beam that light source 10 sends reaches electro-optical tubes 8 on the other side through light hole, electro-optical tubes 8 receives light beam conducting afterwards, and the warning device circuit is connected, and realizes reporting to the police, can remind chaufeur to note, chaufeur is done some preparations to situation about might overturn or avoid some roll-over accidents.

The announcement of book and instruction according to the above description, those skilled in the art in the invention can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the present invention is not limited to also should fall in the protection domain of claim of the present invention modifications and changes more of the present invention.In addition, although used some specific terms in this specification sheets, these terms do not constitute any restriction to the present invention just for convenience of description.
