Description

Side curtain van and side curtain sliding travelling mechanism thereof Technical Field The invention relates to the technical field of side curtain van vehicles, in particular to a side curtain van and a side curtain sliding travelling mechanism thereof. Background In the side curtain van-type semitrailer disclosed by the utility model, an upper guide rail is arranged on a longitudinal beam of a van body, a lower guide rail is arranged on a side beam of a frame, and an end sideslip column and a middle sideslip column connected with tarpaulin can slide between the upper guide rail and the lower guide rail. The driving piece is matched with the connecting piece to drive the end sideslip column to slide so as to drive the middle sideslip column to slide, so that tarpaulin fixed on the sideslip column is opened or closed, and the automatic control of a tarpaulin switch is realized. Wherein the driving member is a motor, and the connecting member is a wire rope connected with the end sideslip column 322 a. In operation, the motor drives the wire rope to push or pull the end side-slip column 322a to slide, so that the end side-slip column 322a is linked with the middle side-slip column 322b to slide, and the awning cloth 321 connected between the end side-slip column 322a and the middle side-slip column 322b is unfolded or folded. Although the prior art can automatically realize the opening and closing of the awning cloth, the awning cloth is driven to walk by adopting a steel wire rope, and the most core defect of the awning cloth is the complexity and unreliability of a transmission path. In particular, to achieve a long travel drive, the wire rope must be wound around a plurality of fixed pulleys or guide studs to form a multi-point contact tortuous drive chain. This structure causes the following problems: The friction resistance is generated at each contact point, tension of the steel wire rope is attenuated, driving force transmitted to the tail end sliding frame is obviously weakened and is not constant, relative positions of a plurality of sliding columns are easy to change slightly under the working conditions of running vibration of a carriage and slight deformation of the carriage body, the steel wire rope is easy to jump, clamping stagnation and even instant relaxation at a certain pulley, the whole transmission system is invalid, opening and closing actions of the awning cloth are interrupted, meanwhile, accumulated friction of the plurality of contact points accelerates abrasion of the steel wire rope, obvious transmission hysteresis is generated, accurate and synchronous stable movement of a plurality of side sliding frames is difficult to realize, and the reliability and the service life of the system are seriously influenced. Disclosure of Invention The invention aims at overcoming the defects of the prior art and provides a side curtain van and a side curtain sliding travelling mechanism thereof, which have the advantages of simple structure, direct transmission and reliable operation. In order to achieve the aim of the invention, the side curtain van and the side curtain sliding travelling mechanism adopt the following technical scheme: The side curtain sliding travelling mechanism of the side curtain van comprises a plurality of side sliding carriages which are arranged on two sides of a van body in a sliding mode, the side sliding carriages are connected through tarpaulin, at least one side sliding carriage is an active sliding carriage, the active sliding carriage drives to slide through a power travelling unit, the other side sliding carriages are driven sliding carriages which slide along the active sliding carriage, the power travelling unit comprises a rotating plate arranged at the lower end of the active sliding carriage, the upper end of the rotating plate is rotatably connected with the active sliding carriage through a hinge shaft, travelling wheels which are transversely arranged are arranged on the rotating plate, travelling wheels are provided with travelling driving components for driving the travelling wheels to roll, the lower end of the rotating plate is fixed through elastic clamping pieces, and the rolling surfaces of the travelling wheels are always pressed on the outer side surfaces of frame side beams through elastic force provided by the elastic clamping pieces, so that rolling contact is formed between the travelling wheels and the frame side beams.
