Description

A kind of tarpaulin-type compartment obturator

Technical field

The present invention relates to a kind of compartment obturator, refer to a kind of tarpaulin-type compartment obturator of tip-up lorry especially.

Background technology

Existing tip-up lorry tarpaulin-type compartment obturator, the tarpaulin used is most and compartment is wide, in actual applications, when sandstone rubbish loaded in compartment and other items is higher than compartment, between the both sides of tarpaulin and compartment, just gap can be produced, even if tarpaulin flat cover is at the end face in compartment, because tarpaulin has certain elasticity, when lorry travels, the edge of tarpaulin is easy to start windward, above-mentioned situation very easily causes dropping of goods and airborne dust, causes loss of goods, contaminated environment, widening tarpaulin makes tarpaulin hang down in the both sides in compartment, can solve the problem, but be limited to the requirement of existing structure design and regulation, it is mostly suitable with the width in compartment to be used for the spool length of folding and unfolding tarpaulin, after using the tarpaulin wider than compartment, the unnecessary tarpaulin in both sides cannot by motor retracting on spool, tarpaulin manually must be folded, after the width of tarpaulin is less than the width of spool, motor could be utilized to furl, when closure compartment, folding tarpaulin is also needed to open, be dispersed in the both sides in compartment, manually by the edge of tarpaulin by rope successively bolt on the hook in compartment, in preventing lorry from travelling, the tarpaulin of both sides is lifted by wind, because the frequency of operation of tip-up lorry is very high, loaded down with trivial details processing ease makes people feel exhausted, because the compartment of lorry is higher, folding, open tarpaulin to need to climb compartment, certain hidden danger is brought to the safety of people, and mostly adopt the slideway being located at both sides, compartment for a pair to guide tarpaulin folding and unfolding in existing tarpaulin-type compartment obturator, this type of obturator is when loader plastic of Rockfill in-built to compartment, and some building stones be scattered are easy to smash slideway, cause obturator to lose efficacy.

Summary of the invention

The object of this invention is to provide a kind of tarpaulin-type compartment obturator, the obturator of this technology is combined closely with compartment, and use reliable, anti-goods drops the effective of airborne dust.

Technical scheme of the present invention is: a kind of tarpaulin-type compartment obturator, comprise the loading body of lorry, it is characterized in that: a swing arm is respectively equipped with in the both sides in compartment, one end of two swing arms respectively by hinge and compartment hinged, the other end of two swing arms is connected by the first cross bar, two swing arms are equipped with extension spring respectively, the two ends of extension spring respectively with corresponding swing arm and compartment hinged; Compartment is stamped the tarpaulin of flexible connection, tarpaulin one end and the first cross bar are connected, and the tarpaulin other end and the second cross bar are connected, second cross bar is connected with compartment by bridge, the first described cross bar or the second cross bar are spools, and the middle part cover of spool has support set, and the axle head of spool is connected with motor power; Compartment is equipped with ropewinder, the serving of ropewinder and the edge of tarpaulin affixed, described ropewinder is multiple.

Advantage of the present invention is: the obturator of this technology is combined closely with compartment, and use reliable, anti-goods drops the effective of airborne dust.

When opening tarpaulin, starter motor, motor belt motor spool rotates, and tarpaulin tightens up under the winding of spool, overcomes extension spring power, two swing arms are rotated around respective hinge, complete tarpaulin opening action, when closing tarpaulin, starter motor antiport, extension spring pulls swing arm to playback by the screen resilience of self, makes tarpaulin cover loading body, this device can use the tarpaulin wider than compartment, because spool is when furling tarpaulin, support set can by high for the support of the tarpaulin of retracting central authorities, the tarpaulin of both sides is made to concentrate retracting to the middle part of spool, so the tarpaulin wider than compartment can be furled completely on spool, realize the tarpaulin that automatic deploying and retracting is wider than compartment, ropewinder is after tarpaulin covers compartment, tarpaulin edge can be tightened up, tarpaulin is made snugly to hang down in the both sides of compartment board, tarpaulin is combined with compartment closely, anti-goods is dropped or airborne dust effective, due to the folding and unfolding using swing arm to guide tarpaulin, slideway is comparatively used to guide the obturator of tarpaulin, use more reliable, safeguard simpler.
