Abstract

The utility model relates to a hydraulic pressure pneumatic panel turnover type covering device, comprising the turning shaft of a covering frame arranged on the large box of an automobile via a shaft lever. Two end heads of the turning shaft are fixed with the covering frame, a power-assisted tension spring is arranged between two side arms of the frame and the plate of the large box of the automobile, and a hydraulic cylinder and a controller are fixed to the upper end of the plate of the large box of the automobile. One end of a rocker arm is hinged with a hydraulic piston rod, and the other end of the rocker arm is fixed to the turning shaft. The novel covering opening and closing device has simple control and convenient operation, the labor intensity of drivers is relieved, the loss of goods on the automobile is avoided, and the utility model can be widely used as a covering opening and closing device for the automobile with the large box.

Description

Hydropneumatic turnover plate type tarpaulin device

The utility model relates to the start-stop system of the big boxboard tarpaulin of a kind of dumping car.

At present the big boxboard tarpaulin of automobile opens and closes and finished by hand by driver or other operator fully, wastes time and energy, and is very inconvenient, and especially the goods in big case is fully loaded or load just trouble more of special article.

Task of the present utility model is: overcome the deficiencies in the prior art, design a kind of hydropneumatic turnover plate type tarpaulin device.

Task of the present utility model realizes as follows: it comprises hydropneumatic turnover plate type tarpaulin device by bar holder and is installed in tarpaulin framework trip shaft on the big case of automobile, the two ends of trip shaft is fixed with the tarpaulin framework, between the two side arms of tarpaulin framework and the big boxboard of automobile, the power-assisted extension spring is housed, be fixed on the big boxboard of automobile upper end a hydraulic actuating cylinder is arranged, an end of rocking arm is equipped with in the termination of hydraulic cylinder piston rod by jointed shaft; the other end of rocking arm is fixed on the trip shaft, and hydraulic actuating cylinder is by hydraulic directional control valve, source switch control.

Thereby the utility model rotates the keying that realizes tarpaulin owing to adopt the hydraulic efficiency pressure system of automobile to drive piston rod control tarpaulin framework trip shaft by the valve modulated pressure with cylinder, control is simple, easy to operate, alleviated the labour intensity of chaufeur, the loss of having avoided article on the car be scattered.

Fig. 1 is the utility model front view;

Fig. 2 is that the K of Fig. 1 is to view;

Fig. 3 is a tarpaulin mode of operation view.

A most preferred embodiment of the present utility model, as figure, hydropneumatic turnover plate type tarpaulin device is installed on the big case 9 of automobile, it comprises by bar holder 6 and is installed in tarpaulin framework trip shaft 10 on the big case of automobile, the two ends of trip shaft is fixed with tarpaulin framework 8, between the two side arms of tarpaulin framework and the big case of automobile, power-assisted extension spring 7 is housed, be fixed on the big boxboard of automobile upper end and be fixed with a hydraulic actuating cylinder 3, the hydraulic cylinder piston rod termination is hinged with an end of Rocker arm 4; the other end of rocking arm is fixed on the trip shaft 10; hydraulic actuating cylinder is by hydraulic directional control valve 11; control cock 13 and cut-off switch 12 controls; the cut-off switch effect is cut off the power supply stop control lever when trip shaft reaches certain angle hydraulic actuating cylinder rear-end collision on cut-off switch.

Trip shaft is provided with safety link 14, and its effect is to prevent the bar holder accidental damage.

Second kind of embodiment of the present utility model, as shown in Figure 3, hydraulic actuating cylinder 3 is fixed on the facade of big boxboard.
