Description

Side curtain sliding mechanism for side curtain van Technical Field The invention relates to the technical field of side curtain van vehicles, in particular to a side curtain sliding mechanism for a side curtain van. Background At present, the conventional curtain opening and closing mechanism of the side curtain van-type semitrailer generally adopts a mode of adopting a motor to fix and match with a steel wire rope for traction, namely, the motor is fixedly arranged at the front end or the rear end of a carriage, an end sliding column is pulled by the steel wire rope, and the end sliding column drives the rest middle sliding columns to move, so that the tarpaulin is opened or closed. For example, an electric bidirectional integral sliding tarpaulin for a vehicle in the prior art has an authorized bulletin number of CN 206510818U and an authorized bulletin day of 2017.09.22. However, this driving method has the following problems in practical use: Firstly, because a steel wire rope is used as a transmission medium, the sliding column is easy to loose, wear and even break after long-term use, so that the sliding column is not synchronous in movement or is not tightly closed, and the maintenance is frequent; Secondly, wire rope transmission is influenced greatly by frame deformation, when the frame is deformed due to the fact that cargoes are loaded on the vehicle, sliding column clamping stagnation is easily caused by the fact that the parallelism of the guide rail is changed, and transmission errors are further aggravated. Disclosure of Invention The invention aims to overcome the defects of the prior art, and provides a side curtain sliding mechanism for a side curtain van, which has a simple structure and is direct in transmission, and the running stability and the running synchronism are improved. In order to achieve the aim of the invention, the side curtain sliding mechanism for the side curtain van adopts the following technical scheme: The side curtain sliding mechanism for the side curtain van comprises a plurality of side sliding frames which are arranged on two sides of a van body in a sliding mode, the side sliding frames are connected through tarpaulin, at least one side sliding frame is a driving sliding frame, the driving sliding frame is driven to slide through a power walking unit, the other side sliding frames are driven to slide along with the driving sliding frame, the power walking unit comprises walking wheels arranged at the lower end of the driving sliding frame, sliding guide rails are arranged on the outer side faces of frame side beams, the walking wheels are vertically arranged and are in rolling contact with the tops of the sliding guide rails, a walking driving assembly for driving the walking wheels to roll is arranged on the walking wheels, the walking driving assembly comprises a motor, and an output shaft of the motor is connected with the walking wheels through a gear set.
