Description

TECHNICAL FIELD

[0001] The utility model relates to bridge deck cleaning technical field, concretely relates to automatic unmanned shot blasting detection machine for steel bridge deck. BACKGROUND

[0002] Cable-stayed bridge and suspension bridge are the main structure forms of modern long-span bridges, especially when erecting long-span super-large bridges in places where it is not easy to build bridge piers, such as across large rivers, bays, etc., these two bridge types are often chosen. For long-span suspension bridges and cable-stayed bridges, the self-weight of steel box girder is about 1 / 5-1 / 6.5 of the self-weight of PC box girder. The self-weight of orthotropic steel plate structure bridge deck is about 1 / 2-1 / 3 of the self-weight of reinforced concrete bridge deck or precast prestressed concrete bridge deck. Therefore, long-span bridges greatly affected by self-weight are very beneficial in structure form of orthotropic plate steel box girder. Since the steel bridge deck is in a relatively humid environment for a long time, it needs to be regularly maintained according to the situation.

[0003] The Chinese patent with publication number CN213970676U discloses a vertical shot blasting machine, which comprises a vertical movable frame, a controller, a main machine, a dust collector, a shot receiving mechanism and a fixing mechanism. The controller, the main machine, the dust collector, the shot receiving mechanism and the fixing mechanism are all arranged on the vertical movable frame. The main machine comprises a sand box and a shot blasting structure. The sand box is located above the shot blasting structure. The sand box is open upward. The bottom of the sand box is in communication with the shot blasting structure, and the side of the shot blasting structure is in communication with the side of the sand box. The utility model changes the structure of the traditional shot blasting machine, so that the main machine and the sand box are arranged vertically. The included angle between the shot injection pipe and the shot launching pipe and the included angle between the shot launching pipe and the shot blasting machine are determined according to the working frequency of the shot blasting machine, the rebound angle of the shot blasting, etc. This ensures that the vertical surface shot blasting can be carried out, and all the shot blasting can be bounced back to the sand box through the shot recovery pipe, greatly improving the shot blasting quality and speed.

[0004] However, the above technical solution has the following disadvantages: the shot blasting machine cooperates with the movable frame to perform simple shot blasting work on the steel bridge deck. On the one hand, the movement is not flexible enough, resulting in low work efficiency. On the other hand, the shot launching pipe of the shot blasting machine is usually fixed, the spraying angle is limited, the spraying range is effective, and blind spots are likely to occur, affecting the overall shot blasting effect.
