Description

The automatic plug-type environmental-protection cover of engineering truck

Technical field: the utility model relates to a kind of protective cover that is installed in engineering truck container top.

Background technology: along with deepening continuously of Chinese society doctrine material progress and cultural and ideological progress construction, and implementing of China's " the city appearance of the city and environmental health management rules " carried out, strengthen the management of the city appearance of the city and environmental health, creation cleaning, graceful work, the requirement of living environment have caused the great attention of various places government.Government department has made for the domestic shipment bulk freight of engineering truck, surflaes, rubbish and has prevented the specific requirement of leaking, dropping.At present engineering truck generally is a face shield lastblock tarpaulin on container, to prevent leakage such as dust.But adopt this mode to exist to lose time, labor strength is big, and the bad shortcoming of sealing effectiveness, ZL00232407 has announced a kind of " sealed type dumping car top cover actuating mechanism " September 26 calendar year 2001, this device exists complex structure, problem that cost is high.

The utility model content: for solving the problem that prior art exists, the utility model provides a kind of engineering truck automatic plug-type environmental-protection cover, and this protective cover has solved the problem that workman's existing labour intensity of face shield tarpaulin on the vehicle container is big, lose time; It has also solved the high problem of complex structure, cost that existing same device exists.The automatic plug-type environmental-protection cover of engineering truck of the present utility model comprises tarpaulin 1, it also comprises several frameworks that are parallel to each other 2 that are supported on below the tarpaulin 1, be vertically fixed in the slideway 3 on two side box plates of vehicle, motor 4, the speed reduction gearing 5 that links to each other with motor 4, assembly pulley 6, assembly pulley 6 is by the main wheel 6-1 that is installed on the speed reduction gearing 5 output shaft 5-1, be installed in the tight pulley 6-2 at vehicle side boxboard rear portion and form around wheel rope 6-3 mobile between main wheel 6-1 and the tight pulley 6-2 and with the rotation of main wheel 6-1, the roller at framework 2 two ends is separately positioned on two slideways 3, and the framework 2n of rear side is connected with wheel rope 6-3.The switch of motor 4 is arranged in the operator's compartment of car, and the driver only needs Push switch, can make motor 4 drive speed reduction gearings 5 and assembly pulley 6 work, and wheel rope 6-3 pulling framework 2 moves forward and backward, thereby tarpaulin is stacked or launches, and has realized the opening and closing of protective cover.The utility model has been realized the action of full-automatic opening and closing protective cover, and it has alleviated working strength of workers, and has and move advantage fast and accurately.The utility model is fit to be installed on automatic tipper, engineering truck and the general wagon, have simple in structure, cost is low, the advantage being convenient to install.

Description of drawings: Fig. 1 is a lateral plan of the present utility model, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is the B-B cutaway view Amplified image of Fig. 1.

The specific embodiment one: consult Fig. 1 and Fig. 2, present embodiment is made up of tarpaulin 1, framework 2, two slideways 3, motor 4, speed reduction gearing 5, assembly pulley 6, rear carrier plate 7, curved boom 8, a pair of connecting rods 9 that are hinged.Above two slideways 3, respectively be provided with an assembly pulley 6, each assembly pulley 6 is by being installed in main wheel 6-1 on the speed reduction gearing 5 output shaft 5-1, being installed in the tight pulley 6-2 at vehicle side boxboard rear portion and forming around the wheel rope 6-3 between main wheel 6-1 and the tight pulley 6-2, and the framework 2n of rear side is connected with wheel rope 6-3.Be fixedly connected with horizontal beam 2-2 respectively at each framework 2 two ends, be connected with front wheel 2-4 and rear roller 2-3 respectively in the front and back end of horizontal beam 2-2, front wheel 2-4 and rear roller 2-3 match with slideway 3.Two rollers and horizontal beam 2-2 make framework 2 be in vertical state, can not tilt forwards, backwards.Also be provided with a pair of hinged connecting rod 9 between the roller of adjacent two frameworks, 2 homonymies, the two ends of pair of links 9 are hinged with the wheel shaft of the front wheel 2-4 of the rear roller 2-3 of front side frame 2, rear frame 2 respectively.When tarpaulin strutted fully, pair of links 9 still was bent downwardly and forms the angle less than 180 degree, can prevent that like this pair of links 9 from forming the dead point, influences framework 2 and move forward.The main wheel 6-1 of assembly pulley 6 forms to horizontally slip with the output shaft 5-1 of speed reduction gearing 5 and cooperates, and is provided with key 5-3 between main wheel 6-1 and the output shaft 5-1.When vehicle ', railway carriage can produce vibration and since between main wheel 6-1 and the output shaft 5-1 can about produce a certain amount of slippage, therefore when railway carriage vibrate, can not take turns the tension that the 6-3 that restricts draw.Wheel rope 6-3 around two～three circles, can guarantee that like this main wheel 6-1 driven wheel rope 6-3 moves on main wheel 6-1.Back edge at tarpaulin 1 also is fixedly connected with rear carrier plate 7, the front lower place at rear carrier plate 7 two ends respectively is connected with a curved boom 8, below each slideway 3 rear end, also be connected with one section vertical secondary slideway 3-1 that is provided with, form arc transition between slideway 3 and the secondary slideway 3-1, hinged with the rear roller 10 of slideway 3 and secondary slideway 3-1 bearing fit with the lower end of curved boom 8.When protective cover was closed, rear roller 10 fell under gravity among the secondary slideway 3-1, and this moment, curved boom 8 and rear carrier plate 7 were propped up tarpaulin 1 back, and the railway carriage back is covered; When protective cover was opened, 10 of rear rollers can enter in the slideway 3 and to reach.

The specific embodiment two: consult Fig. 3, what present embodiment and the specific embodiment one were different is: also be provided with a support roller 11 in the inboard of each framework 2 lower end, support roller 11 is installed on the bracing frame 12, bracing frame 12 is captiveed joint with framework 2, and support roller 11 withstands on the medial surface 3-2 of slideway 3.The effect of support roller 11 is to prevent that framework 2 from swinging.Other composition and annexation and

The specific embodiment one is identical.
