In response to the above-described existing problems, the present utility model provides a new tarpaulin system for automatic or manual covering of the opening of the compartment of a truck (e.g., a high-rise cargo). The awning cloth system provided by the utility model can realize small space occupation ratio and light weight when the awning cloth of the awning rod is recovered; the awning cloth system has the advantages of good sealing performance, convenient operation during unfolding, great improvement of the effective loading length of the cargo compartment, good flexibility, space saving, high reliability and convenient use.

Specifically, the technical scheme adopted by the utility model is as follows: an overlapping tarpaulin system mainly comprises a tarpaulin, a tarpaulin rod and a pulley assembly. One side of the awning cloth is fixedly connected with the side surface of the carriage, and the awning rod penetrates through the other side of the awning cloth to drive the awning cloth to move; the pulley assembly consists of a plurality of pulleys and ropes which drive the pulleys to rotate and form a closed loop, and the ropes are fixedly connected with the awning rods and used for driving/pulling the awning rods to move so as to realize the unfolding and folding of the awning cloth.

Further, the pulley assembly comprises four pulleys, and the four pulleys and a closed loop rope form a group of (fixed) pulley blocks for pulling the awning rod to move. The first pulley is positioned at the lower part of the side surface of the carriage, so that the rope can be pulled manually; the second pulley and the first pulley are positioned on the same side of the carriage and are fixed above the top angle of the side of the carriage; the third pulley is fixed above the opposite side top angle of the carriage, and the awning rod moves between the second pulley and the third pulley along with the driving of the rope so as to realize the unfolding and folding of the awning cloth; the fourth pulley is located below the inner side of the second pulley for forming a closed loop for rope running.

Preferably, the awning cloth system has two awning cloths (a first awning cloth and a second awning cloth) and is thus respectively threaded with a first awning rod and a second awning rod; when the awning cloth is unfolded to cover the roof, the first awning cloth and the second awning cloth are overlapped at the top of the carriage and are fixed and sealed through the awning cloth lock hooks. Preferably, the overlap is 500-700mm wide to achieve a seal against the cabin.

Wherein, first tarpaulin rod, second tarpaulin rod are connected to the rope respectively, are located the different pulley sections at the roof of the car. For example, in the four-pulley embodiment described above, the first canopy bar moves between the second pulley and the third pulley (rope pulley segment) as the rope is pulled, and the second canopy bar moves between the third pulley and the fourth pulley (rope pulley segment). Thus, the movement of the two awning levers from the recovery position to the unfolding limit position has partial up-and-down overlapping, so that the overlapping of the two awning cloths is realized.

Further, one side of the tarpaulin is connected with the side surface of the carriage in a riveting or pressing and fixing mode.

Preferably, the pulley assembly is located at any section of the carriage (any section of the head, tail or period), and rails for the movement of the canopy rod are provided on the front and rear distal sides of the carriage away from the pulley assembly, so as to realize the synchronous movement of the distal ends.

Preferably, the pulley assembly is 2 groups of pulley blocks which are respectively positioned at the front side and the rear side of the carriage and synchronously driven by a motor.

The tarpaulin system can be used for controlling the tarpaulin by pulling the rope through electric or manual operation. The tarpaulin realizes the covering and sealing of the top of the carriage in a mode of oppositely moving and overlapping up and down butt joints through a rope and pulley system; after the tarpaulin is lapped and sealed, the tarpaulin locking hook can be used for fixing the tarpaulin, so that the tarpaulin system is stable and reliable. Thereby realizing the advantages of good realization flexibility, space saving, high reliability and convenient use.

Further, the guide is of a pulley block structure; other various slidable arrangements are possible.

Detailed Description

The "tarpaulin system" of the present utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1, taking a rear door of a general high-rise cargo as an example, the structure of the tarpaulin system provided by the present utility model is shown. The system mainly comprises a tarpaulin 3, a tarpaulin rod 4 and a pulley assembly (rope 1 and pulley block 2).

As shown in fig. 1-3, the present example chooses to mount a pulley assembly at the tail (cross section) with the first pulley for manually pulling the cable 1 on the right side of the tail (as shown in fig. 1 and 3). Preferably, a preset rail for the distal end synchronous movement of the two slide rods may be installed at the front of the car. Of course, the same pulley assemblies can be arranged at the front part of the carriage, and the motor is synchronously driven to realize linkage.

The left and right sides of the carriage are respectively provided with a tarpaulin 3, and one side of the tarpaulin 3 is fixedly connected with the side surface of the carriage (riveted or pressed and fixed), as shown in fig. 2. The other side of the awning cloth 3 (holes are uniformly distributed) is perforated and supported by the awning rod 4 and drives the awning cloth 3 to move (release and recovery) on the roof of the vehicle. When the tarpaulin is unfolded to cover the roof, the two tarpaulins 3 are overlapped at the top of the carriage and are fixedly sealed through the tarpaulin locking hooks 5.

The rope 1 (fixedly) is connected with one end of the awning rod 4 and is used for driving/towing the awning rod 4 to move, so that the awning cloth 3 is unfolded and folded.

As shown in fig. 1, the pulley block 2 is arranged at the top corner of the carriage, and can be connected or welded and fixed. The pulley block 2 is provided with four pulleys and forms a pulley assembly with the rope 1. Wherein the first pulley is positioned at the lower right side of the vehicle door (carriage); the second pulley is positioned above the right vertex angle of the vehicle door; the third pulley is fixed above the left vertex angle of the vehicle door; the fourth pulley is positioned below the inner side of the second pulley; the rope is thus passed around the pulleys (over the second and fourth pulleys) forming a closed loop and four pulley segments of the rope 1. The first pulley section and the fourth pulley section of the rope 1 are manual pulling sections; the second pulley section is the movement section of the awning pole 1 of the right awning cloth 3, and the third pulley section is the movement section of the left awning cloth 3/awning pole 4. The movement of the two tent poles 4 from the recovery position to the deployment limit position has a partial overlap (fig. 3) up and down, so that the above-mentioned overlapping of the two tent cloths 2 is achieved.

The working principle of the closed state of the awning cloth system is as follows:

when the awning cloth system is opened, the rope 1 (the fourth pulley section) is pulled by hand, the two awning cloths 3 with one side fixed on the carriage are driven by the awning rods 4 penetrating through the awning cloths 3 to move oppositely to realize sealing through lap joint through guiding by the pulley blocks 2, and in order to prevent the awning cloth system from loosening, the movable end head riveting annular hole or the joint of the awning cloth 3 is fixed on the awning cloth lock hook 5 to realize locking, so that the manual switch is safe, practical and reliable.

The working principle of the tarpaulin system in the opening state of the utility model is as follows:
