Description

Technical Field

[0001] The utility model belongs to the field of bridge maintenance equipment, and in particular relates to a cleaning device for the outer side of a bridge anti-collision wall with a distance-adjustable structure. Background Art

[0002] An elevated expressway is a three-dimensional transportation system primarily designed to improve urban transportation efficiency and alleviate congestion. Typically constructed as a bridge over existing roads, it creates a separate traffic flow, reduces the number of intersections and traffic lights, and improves speed and safety. The design of an elevated expressway typically includes a central divider, full access control, controlled entrance and exit spacing and form, and features either two lanes in one direction or more, along with supporting traffic safety and management facilities.

[0003] After the construction of an elevated expressway, proper maintenance and repair is crucial for extending its lifespan and effectively improving the cityscape. During the maintenance and repair process, the exterior sidewalls of the elevated expressway present a particular challenge, primarily due to their suspended, outward-inclined nature. Both maintenance and repair procedures present significant risks and challenges. Flushing the exterior side of the elevated expressway from within the wall is challenging due to the negative angle. Using a spray-washing vehicle often struggles to adapt to different road sections, and controlling the distance between the vehicle and the wall is difficult when passing through ramp bends. Spray-washing efficiency is generally low when passing through special sections such as ramps.

[0004] In order to solve the above problems, the present invention hopes to provide a device for cleaning the outside of a bridge crash barrier with an adjustable distance structure. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] A cleaning device for the outer side of a bridge collision prevention wall with an abducted structural arm, comprising a moving base 1, and four universal wheels 2 arranged in a rectangular array at the bottom of the moving base 1. Through the universal wheels 2, the flexible movement of the device can be achieved. A fixed column 3 and a push-pull handrail 4 are provided at the moving base 1, and the fixed column 3 and the push-pull handrail 4 are fixedly connected to form a stable support. At the same time, to enhance the stability of the fixed column 3, diagonal fixed columns 3 are provided around the fixed column 3. A folding arm 5 is hinged to the upper part of the fixed column 3, and the folding arm 5 is integrally in a U shape. Through the hinged connection, the left and right folding of the folding arm 5 can be achieved. When the folding arm 5 is turned to the right, the outer arm of the folding arm 5 is located on the right side of the device, which is the form of the folding arm 5 in the normal working state; when the folding arm 5 is turned to the left, the outer arm of the folding arm 5 is located on the upper side of the device, and the device can be transferred and stored in this state. A support column 6 is provided on the left side of the folding arm 5, and the support column 6 is used for fixed support in the state where the folding arm 5 is turned to the left. Correspondingly, a support seat 7 is provided on the left side of the moving base 1. To ensure the stability of the left and right folding of the folding arm 5, a support angle 8 is provided on the fixed column 3, and the support angle 8 is located on the left side of the fixed column 3.
