Further, in order to make the tarpaulin after this application improves can adapt to the structural feature that the carriage is high back low before to and be convenient for draw in the tarpaulin in and cover and improve sealed effect after accomplishing, this application improves the tarpaulin. The structure of the awning comprises that a folding and unfolding connecting structure 11 and a sealing and locking assembly 12 are arranged on an awning cloth 1, the awning cloth 1 is movably arranged at the top of a boxcar through the folding and unfolding connecting structure 11 under the matching of an opening and closing driving device, and the unfolded awning cloth 1 is locked on the outer side wall of the periphery of the boxcar through the sealing and locking assembly 12. Correspondingly, lateral compensation skirts 13 which are gradually widened outwards along the length direction are further arranged on two sides of the awning cloth 1, an end compensation skirt 14 is arranged at the front end of the awning cloth 1, the width of the lateral compensation skirt 13 at the front end of a carriage is larger than that at the rear end of the carriage, the sealing and locking assemblies 12 extend along the free edges of the corresponding lateral compensation skirts 13, the width of the end compensation skirt 14 is matched with the heightened height of the front end of the carriage, and the parts of the sealing and locking assemblies 12 at the front end extend along the free edges of the end compensation skirts 14. At this time, the preferable structure of the sealing and locking assembly 12 is a rubber band extending along the circumference of the tarpaulin 1 or a binding rope fixed on the circumference of the tarpaulin 1 at intervals; the preferred mode of the folding and unfolding connecting structure 11 comprises four groups of canopy buckles 15 which are arranged on the canopy cloth 1 at intervals along the width direction and extend along the length direction, and the four groups of canopy buckles 15 are uniformly distributed along the width direction. The improved covering tarpaulin has the advantages that the skirt edge is additionally arranged, the sealing effect is improved through the sealing locking assembly 12, the connecting structure 11 is additionally arranged to be folded and unfolded, the tarpaulin can be conveniently connected with the steel rope, the tarpaulin is prevented from being damaged in the process of folding and unfolding, and the service life of the tarpaulin is prolonged.

Simultaneously, in order to suit with the torsion bar spring or the structure of extension spring group of self-sustaining formula canopy mechanism, and improve the inconsistent problem of length of the cable of receiving and releasing tarpaulin after receiving and releasing to take one's place, this application has improved door type support. The specific structure is that the door-shaped support 2 comprises a door-shaped support body and a stranded rope compensation system 17 arranged on a horizontal rod 16 of the door-shaped support body along the length direction, the door-shaped support body is hinged on the outer side wall of the corresponding side of the boxcar through the lower end of a vertical rod 18 of the door-shaped support body, and the length difference of each steel rope for winding and unwinding the covering tarpaulin in the winding and unwinding process is compensated through the stranded rope compensation system 17. At this time, the projections of the two vertical rods 18 on the outer side wall of the carriage are in a zigzag shape with a long side and a short side, the zigzag vertical rods 18 are hinged on the outer side wall of the carriage through the long sides of the zigzag vertical rods, and two ends of the horizontal rod 16 are respectively hinged with the free ends of the short sides of the corresponding vertical rods 18. Correspondingly, the preferable mode of the stranded rope compensation system 17 comprises a plurality of extension springs with the number equivalent to that of the external steel ropes, each extension spring is connected with the horizontal rod 16 of the door-shaped bracket body through one end, and each extension spring is connected with the corresponding steel rope through the other end.

In particular, the improved working principle of each part is as follows,

tarpaulin support frame horizontal pole schematic diagram illustrates:

because the tarpaulin is drawing in, the steel cable is in inhomogeneous subsection state in the capstan winch, and the error can appear in the girth that the steel cable twined in the capstan winch, and the number of turns that twitches when every capstan winch draws in is unanimous, has just caused the support frame to draw in the assigned position in the anterior top of carriage after drawing in, and one end has not reached the situation of assigned position yet. In order to solve the problem, the spring device is distributed on the cross rod, the principle is that the steel rope twisted firstly can stretch the spring at this time, so that the winch can continue to operate, other winches which do not twist the steel rope can twist the steel rope which is not twisted into the winch, and the winch can be completely folded to enable the tarpaulin support frame and the cross rod to be horizontally placed at the top of the front end of the carriage, so that the potential safety hazard caused by the fact that the vehicle runs in an ultrahigh mode can be avoided.

The working principle of folding and covering the tarpaulin is as follows:

when the motor system drives the winch to wind the steel wire rope to pull the support and the tarpaulin to be folded at the top of the front end of the carriage, the spring is stretched to store the energy for pulling the support to cover the tarpaulin towards the rear of the carriage, the function can be realized by one spring in the design of the spring, but the design has the advantages of using two springs that the energy storage capacity is easy to control, and the durability of the spring is enhanced.

This design can also not use extension spring to change into torsion bar spring and realize this function, and the hinge point and the torsion bar spring fixed connection of support lower extreme, torsion bar spring store energy when the support moves the carriage front end, and the advantage of this design is:

1 can avoid extension spring external in carriage both sides, easy damage.

If the spring 2 damages when tensile state can release energy in the twinkling of an eye and have certain potential safety hazard, the torsion bar spring mounting can install in closed cavity bottom the carriage, even if damage can not cause any safety problem to take place yet.

Description of design principle of tarpaulin:

the steel rope 1 penetrates through the tent buckles of the tent cloth, the purpose of uniformly folding and recycling the whole tent cloth when the tent cloth is folded, and the tent cloth slides to the specified position on the steel rope through the tent buckles when the tent cloth is unfolded, so that the purpose of accurate control is achieved.

And 2, rubber bands on two sides of the tarpaulin can effectively bind two sides of the carriage to prevent the goods from leaking and polluting.

Tarpaulin control and transmission mechanism operation principle diagram

The remote controller sends a switch instruction to the control sensor to control the motor to rotate forward and backward, and drives the transmission shaft and the winch to wind and wind the steel rope, so that the tarpaulin is folded and covered.

The control sensor can control the automatic stop function of the awning cloth after being folded and covered in place, and can upload the running state information to a transportation monitoring party through a vehicle-mounted GPS.
