The utility model content

At above the deficiencies in the prior art, the purpose of this utility model provides a kind of convenient truck body tarpaulin that uses and actuates device automatically.

The utility model is finished like this: a kind of truck body tarpaulin actuates device automatically, tarpaulin rod is arranged, chute, slide unit, antifriction-bearing box, cable wire, around wheel, roller, pulley, transmission shaft, gear and motor, it is characterized in that: the outside wall surface top of container both sides side plate respectively is fixedly connected with a chute along its length, the bottom respectively is fixedly connected with a slide unit along its length, before the container side plate outside wall surface between chute and slide unit, two of being fixed with respectively around cable wire in rear end are coaxial around wheel and a roller, and cable wire two ends of twining roller is fixed in two respectively on taking turns with the contact potential differences of 180 degree; Be assemblied in the chute and can before and after a plurality of antifriction-bearing boxs of sliding corresponding one by one continuous with the many tarpaulin rods on container both sides, the pulley that move before and after can be on slide unit tarpaulin rod lower end and links to each other, a tarpaulin rod of rearmost end links to each other with cable wire by the tarpaulin rod button, every tarpaulin rod links to each other with tarpaulin by the tarpaulin clasp, and two ends are equipped with two coaxial transmission shaft middle parts around wheel and are meshed by the driven wheel of driven gear with the motor power output shaft.

Described chute is a concave groove, is connected with the angle steel type slide unit on the container side plate outside wall surface of chute below 30～40cm.

Described truck body tarpaulin actuates device automatically, first tarpaulin rod that is positioned at foremost directly is fixedly connected on the container side plate outside wall surface of homonymy, the tarpaulin rod of rearmost end is fixed together by tarpaulin rod button and cable wire, all the other every tarpaulin rod upper end is connected with antifriction-bearing box in being contained in chute by the tarpaulin rod cover, and the lower end is connected with the pulley that can move on slide unit.

The beneficial effects of the utility model: it is assemblied on the side plate of container both sides, and the tarpaulin rod that tarpaulin has been housed makes tarpaulin rod drive the tarpaulin automatic winding by mechanical drive or opens, and need not time-consuming loading and unloading tarpaulin, thereby reaches the laborsaving safety that saves time.Also can promptly assemble one respectively by shaking the crank that cable wire is moved forward and backward at the transmission shaft two ends of being equipped with around wheel without driven by motor, crank is shaken on both sides simultaneously also can make cable wire move forward and backward equally, receives tarpaulin thereby open.

The specific embodiment

The utility model is described in further detail below in conjunction with the embodiment that provides and accompanying drawing.

As Fig. 1-3, at container side plate 1 from the affixed chute 2 in upper end 5cm place, the right and left symmetry, chute is a groove shaped steel, in adorn a plurality of antifriction-bearing boxs 3, quantity lack one than tarpaulin rod 10 number, it is 5 affixed that rolling bearing axis 4 and tarpaulin rod overlap; Be connected with angle steel type slide unit 15 under the chute on the side plate at 35cm place, chute and slide unit are longer than container 3cm; Between chute and slide unit, be positioned at container side plate outside wall surface front end attaching cable wire around storehouse 11, in be equipped with two coaxial cable wires around the

wheel

16,3 times of length to the cable wire 17 of container total length around cable wire on wheel, two terminations of cable wire are fixed in cable wire respectively in the groove of wheel with the contact potential differences of 180 degree; Be connected with a roller 18 between container side plate rear end outer wall chute and the slide unit, the cable wire folding forms closure after walking around roller; Cable wire is connected with tarpaulin rod button 19, and is affixed by tarpaulin rod button, cable wire and tarpaulin rod of rearmost end; Transmission shaft 9 connects as one the cable wire on side plate 1 both sides around wheel 16, the transmission shaft middle part has the drive wheel 7 on a driven gear 8 and DC machine 6 power take-off shafts to be meshed; Container first tarpaulin rod foremost directly is fixed on the side plate, and all the other the every equal attaching in tarpaulin rod lower end has pulley 14, by the socket of corresponding tarpaulin rod cover, can move in chute and before and after on the slide unit simultaneously; Tarpaulin rod links by a plurality of tarpaulin clasps 13 and tarpaulin 12, guarantees that the tarpaulin on the tarpaulin rod can slippage.
