Vehicle-mounted square cabin traveling device

Abstract

The invention discloses a vehicle-mounted square cabin traveling device, includes a universal traveling wheel mechanism, a directional traveling wheel mechanism and a steering linkage mechanism, and one side of the universal traveling wheel mechanism and the other side of the directional traveling wheel mechanism are fixedly connected with the lower parts of the two ends of the cabin. The upper part of the universal traveling wheel mechanism and the directional traveling wheel mechanism are respectively connected with the bottom of the lifting mechanism, the upper end of the connecting frame is respectively fixed on the middle part of the upright poles at the four corners of the vehicle-mounted cabin frame, and the lower end is respectively fixed on the mounting interface of the vertical plane of the standard container corner assembly at the four corners of the bottom of the cabin frame. The lower parts of the two ends of the steering linkage mechanism are respectively articulated withone end of the transition plate, the lower ends of the lifting mechanism are respectively articulated with the other end of the transition plate, and the front side of the steering linkage mechanismis also provided with an armrest. The vehicle-mounted square cabin traveling device has the advantages of compact structure and convenient use, can control the advancing direction of the vehicle-mounted square cabin, avoids the difficulty in moving or stopping moving of the vehicle-mounted square cabin due to the inconsistent directions of the two universal wheels, and greatly improves the on-sitereaction speed of the invention.

Description

technical field [0001] The invention relates to a movable vehicle-mounted shelter, in particular to a device capable of manpower driving the vehicle-mounted shelter, and belongs to the technical field of vehicle-mounted shelters. Background technique [0002] As a mobile cabin, the vehicle-mounted shelter has the same dimensions as a standard container. It can be loaded on a container transport vehicle or a dedicated vehicle-mounted shelter transport vehicle for long-distance transportation, and can also be dropped from the vehicle to the ground for use or storage. After the vehicle-mounted shelter falls to the ground, it sometimes needs human power to move for a short distance, such as going in and out of the warehouse or moving on the road for a short distance. After the existing vehicle-mounted shelter is lowered to the ground, it is usually supported by 4 independent walking wheels (generally 2 universal wheels and 2 directional wheels) so that the bottom is off the grou...

Problems solved by technology

However, the existing running devices at the bottom of the vehicle-mounted shelter generally have the following problems: it is easy to get stuck when the road surface is uneven, and it is difficult to turn; it is difficult to keep the direction of the two universal wheels in the same direction when turning, and a large traction / pushing force is required To eliminate the angle difference between the two universal wheels

When the road surface is uneven, according to the principle of supporting a plane by three points that are not on a straight line, there must be a working condition where three traveling wheels support the vehicle shelter. When one of the universal wheels is suspended in the air, due to its steering The bearings are relatively flexible, and the universal wheels are usually in a state of free rotation during the suspension process (unless the two universal wheels are kept at the same azimuth angle by hand or other tools, but the operation is too cumbersome), resulting in this universal wheel landing again. The direction of the vehicle-mounted shelter cannot be guaranteed. If the azimuth angle of the other universal wheel differs greatly or the two are in a perpendicular state, it will be difficult to move the vehicle-mounted shelter or the movement will stop, which is not conducive to short-term human-driven driving of the vehicle-mounted shelter. distance transport
