Description
Technical field
The utility model relates to a kind of transport vehicle auxiliary devices, and in particular to a kind of automatic open covering device.
Background technique
Paving mix transport and discharge operation in, transport vehicle covering tarpaulin be it is necessary in current national codes, mix
Close material charging finish and transportational process in must assure that covering tarpaulin, with prevent in site operation because a variety of causes wait, cause
Mixture moisture scatter and disappear, while cover tarpaulin can effectively prevent Changes in weather burst rainfall.Therefore the front and back field in conventional construction
Mixture transport vehicle, which is both needed to two workers of configuration, to be responsible for taking off lid tarpaulin, and manually take off lid tarpaulin speed restricts discharging speed slowly, takes
When it is laborious and increase input cost, while manually climbing to roof and taking off lid tarpaulin with some potential safety problems.
Utility model content
The technical problems to be solved in the utility model is that transport vehicle tarpaulin is hung by manpower paving, manually takes off lid behaviour in the prior art
The shortcomings that it is inconvenient to make, and there are personal safety hidden danger.
The utility model provides the device that a kind of tarpaulin spreads extension, automatic open automatically, tool to solve above-mentioned technical problem
Body scheme is as follows:
A kind of transport vehicle tarpaulin automatic cover-taking off device, including the tarpaulin reel being mounted on before transport vehicle at the top of carriage, tarpaulin
High-intensitive wind spring is equipped in reel；Tarpaulin one end is fixed on the tarpaulin reel, and is integrally wrapped on tarpaulin reel；Transport
Intermediate position is equipped with axle bed below vehicle two side carriage plate, is equipped with worm gear in axle bed, and worm gear shaft end is fixedly installed with pivoted arm, pivoted arm from
It is located above compartment by end, pull rod is installed between two pivoted arm free ends, the tarpaulin other end is fixedly connected on pull rod；The worm gear
It is driven with tarpaulin reel by being located at 12V the or 24V direct current generator before compartment on the outside of carriage, the switch of direct current generator is equipped with driver's cabin
It is interior.
This structure drives pull rod to swing by worm gear, and pull rod is moved to compartment rear portion from compartment front end, makes the automatic bedding of tarpaulin
Firmly interior material.
Further, car body top is equipped with distance-sensor and displacement sensor for incuding mixture filling height.
This structure facilitates driver to know material entrucking situation, and the automatic bedding of manual operation is not needed after can also realizing material entrucking and is covered with mat
Cloth, more convenient work.Inductor can also be used in control survey tarpaulin and uncover distance.
Further, it is additionally provided with tension spring, which is connected in the middle part of pivoted arm, and the other end is mounted on compartment rear portion.
Tension spring can help pivoted arm to pull the tarpaulin in tarpaulin reel, mitigate the operating pressure of worm gear.
Preferably, the pivoted arm free end is smaller than its worm gear installation end.
Detailed description of the invention
Mounting structure of Fig. 1 present apparatus on compartment；
Fig. 2 the utility model is based on the angle of depression Fig. 1 structure.
In figure: preceding carriage 1, tarpaulin reel 2, direct current generator 3, tarpaulin 4, pivoted arm 5, side compartment 6, worm gear 7, tension spring 8, pull rod
9。
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing:
As shown in Figure 1, 2, a kind of transport vehicle tarpaulin automatic cover-taking off device, including being mounted on 1 top of carriage before transport vehicle
Tarpaulin reel 2, tarpaulin reel 2 is interior to be equipped with high-intensitive wind spring；4 one end of tarpaulin is connect with the tarpaulin reel 2, and is integrally wrapped in
On tarpaulin reel 2；The intermediate position in two side carriage plate of transport vehicle, 6 lower section is equipped with axle bed, is equipped with worm gear 7 in axle bed, 7 shaft end of worm gear is fixed
Pivoted arm 5 is installed, the free end of pivoted arm 5 is located above compartment, and two pivoted arms is equipped with pull rod 9 between 5 free end；4 other end of tarpaulin
It is fixedly connected on pull rod 9；The worm gear 7 and tarpaulin reel 2 are by being located at 12V the or 24V direct current generator in 1 outside of carriage before compartment
The switch of 3 drivings, direct current generator 3 is equipped in driver's cabin.
When this device carries out tarpaulin bedding, by driver's control switch, the automatic release tarpaulin 4 outward of tarpaulin reel 2 is drawn simultaneously
Bar 9 by tarpaulin 4 to pulling after vehicle, until manually consolidating from deck position by tarpaulin 4 after tarpaulin bedding lives whole materials in entire compartment
It is fixed, and after tarpaulin reel 2 powers off, internal high-intensitive wind spring realizes the power of backrush to tarpaulin 4, and 4 both ends of tarpaulin all generate drawing
It tries hard to keep and demonstrate,proves surfacing.When tarpaulin 4 is torn off, worm gear drives pivoted arm 5, and just pull rod 9 is slowly mobile to compartment front end, high-intensitive wind spring
It voluntarily pulls back tarpaulin 4, final tarpaulin 4 is again in rollback tarpaulin reel.
Further, car body top is equipped with distance-sensor and displacement sensor for incuding mixture filling height.
This structure facilitates driver to know material entrucking situation, and the automatic bedding of manual operation is not needed after can also realizing material entrucking and is covered with mat
Cloth 4, more convenient work.Inductor can also be used in control survey tarpaulin and uncover distance.
Further, it is additionally provided with tension spring 8, which is connected to 5 middle part of pivoted arm, after the other end is mounted on compartment
Portion.Tension spring 8 can help pivoted arm 5 to pull the tarpaulin 4 in tarpaulin reel, mitigate the operating pressure of worm gear 7.
Pivoted arm described in the utility model is preferred, and worm gear connecting pin is thicker, guarantee pivoted arm rigidity, and its free end ratio
Worm gear installation end is smaller, this process can gradually change, and pivoted arm is conical by its shape.This structure is to mitigate pivoted arm top-heavness, is subtracted
Lever force when few pivoted arm rotation.
Present apparatus investment is small, can effectively avoid the security risk during manual operation, carries out tarpaulin by mechanical structure
It bedding and tears off, faster, tarpaulin is laid with also more smooth speed, improves work efficiency.
