Description

A kind of compartment with tarpaulin

Technical field

The present invention relates to a kind of compartment, particularly a kind of compartment with tarpaulin.

Background technology

Along with the more and more attention of people to environment, vehicle or the engineering truck of transportation article need to cover in traveling process, prevent that dirt from splashing or dust fills the air, and therefore wish, at the top in compartment, tarpaulin is installed.For dustproof measure, be to open by resisting stubbornly to back down mostly in the market, two with car length isometric, width be box width half left and right steel plate, connection mode by hinge is fixed on both sides, compartment by two block plates, when loading, two block plates put down, with compartment two outer panel laminatings, after goods is filled, again two block plates are dug, covered and filling on the compartment of goods, yet this mode dust-proof effect is very bad, aesthetic property is extreme difference also, is also difficult to realize automation.

The traditional tarpaulin car of minority adopts tarpaulin rod to support tarpaulin, along the length direction in compartment, is evenly provided with multiple tracks tarpaulin rod, and it is inverted U-shaped that tarpaulin rod is mostly, and two ends are supported on respectively the both sides of box width direction.Fixing tarpaulin rod and tarpaulin are unfavorable for entrucking, before entrucking, wish that tarpaulin is folded into front portion, compartment; After entrucking, wish that tarpaulin launches compartment to cover.Common way is, the two ends of tarpaulin rod are plugged on respectively on slide block, and slide block is supported on respectively on guide rail, by rope traction two end slide block synchronizing movings, end tarpaulin rod is moved, thereby step by step tarpaulin rod is pulled out, and makes tarpaulin cover gradually compartment.

Because some is poor with the working environment in the compartment of tarpaulin, for example article car usually has dirt to drop on guide rail in entrucking process, causes slide block smooth and easyly not advance.Different according to the purposes in the compartment with tarpaulin, sometimes wish the higher of tarpaulin support, away from compartment upper port; Sometimes wish that tarpaulin is lower, near compartment upper port, etc.; So need to develop multiple difform slide block, cause mould development cost large.

The height of tarpaulin rod is all identical from front to back with the compartment of tarpaulin for tradition, when the tarpaulin rod of extreme end is pulled to rear end, compartment, car body top is hidden by the tarpaulin of top completely, but the rear port of afterbody tarpaulin rod forms a hole, need to be by manually taking other tarpaulin by its sealing and tying up fixing, waste time and energy, affect entrucking efficiency.

For convenience of the hole of closed rear end, can the tarpaulin rod of a swing be set at van afterbody, afterbody tarpaulin rod is turned to level attitude around fulcrum, can make the tarpaulin of afterbody form the effect of similar arc sunshade, rear port is sealed.

Existing van takes both sides, compartment by steel rope system separately, to be drawn respectively, the steel rope that is left side, compartment is driven by left side pulley set, the steel rope on right side, compartment is driven by right side pulley set, in use easily there is the error of both sides steel rope miles of relative movement, cause the difference of tarpaulin rod two ends miles of relative movement, cause the skew of tarpaulin rod and tarpaulin motion.

Summary of the invention

The object of the invention is to, overcome problems of the prior art, a kind of compartment with tarpaulin is provided, during loading, tarpaulin can be folded in to front portion, compartment, after loading, can cover above compartment.
