Description

Gantry crane with accurate positioning Technical Field The utility model relates to the field of hoisting mechanical equipment, in particular to a gantry crane with accurate positioning. Background The portal crane is hoisting equipment widely applied to outdoor goods yards, stock yards, ports and other places, has a metal structure similar to a portal frame, can directly walk on a ground track, and has the characteristics of high field utilization rate, large operation range, wide application range, strong universality and the like. The hoisting position of the object hoisted by the portal crane is fixed with the hoisting end position, so the hoisting accuracy is required to a certain extent, but because the portal crane is used for hoisting most of objects with large volume and large mass, the positioning is inconvenient, the shifting is easy to occur, and particularly for some materials hoisted in batches, the accurate positioning to the appointed position is inconvenient, and the operation efficiency of the crane is seriously influenced. Disclosure of utility model The utility model aims to provide a portal crane with accurate positioning, which feeds back the position of a lifting appliance in real time through shooting of an industrial camera, and adjusts the position of a trolley through the distance between the lifting appliance and an object, so that the lifting appliance is accurately abutted with the object, and the lifting efficiency is improved. The gantry crane comprises a large trolley travelling mechanism, supporting legs, a main beam and a trolley, wherein a track is arranged on the main beam, the trolley runs on the track, the trolley comprises a trolley frame, a sliding frame and a winding drum mechanism, the top of the trolley frame is horizontally provided with sliding rails, the arrangement direction of the sliding rails is mutually perpendicular to the arrangement direction of the track, the bottom of the sliding frame is provided with sliding grooves matched with the sliding rails, the sliding frame is connected onto the trolley frame in a sliding manner through the sliding rails and the sliding grooves, a cylinder is hinged between the trolley frame and the sliding frame, the winding drum mechanism is arranged on the sliding frame, a lifting appliance is arranged below the trolley and comprises a mounting plate, an industrial camera is arranged on the mounting plate, the top of the mounting plate is provided with a movable pulley block, the movable pulley block is connected with the winding drum mechanism through a steel wire rope, and the bottom of the mounting plate is provided with a lifting hook. Optionally, the bottom fixedly connected with link of carriage, the bottom of link is located the girder below, installs anti-sway mechanism between link and the mounting panel. Optionally, the anti-swing mechanism has two sets of just install the both sides of link respectively, and every anti-swing mechanism of group includes two articulated seats, and two articulated seats are fixed connection respectively in link bottom and mounting panel top, and articulated on the articulated seat have the connecting rod, and two connecting rod tip articulates. Optionally, the two groups of anti-swing mechanisms are arranged in a staggered manner. Alternatively, the industrial camera is provided with two and is provided at both ends of the diagonal of the mounting plate, respectively. The gantry crane with accurate positioning has the following advantages: (1) The cart travelling mechanism can move the lifting appliance to the vicinity of the object, then the actions of the lifting cart and the air cylinder are controlled through the data feedback of the industrial camera, and the movement of the lifting appliance is accurately controlled, so that the object is quickly and accurately lifted or put down, and the lifting operation efficiency is improved. (2) The anti-swing mechanism can ensure the stability of the lifting appliance, and when the trolley moves or the cylinder pushes the sliding frame, the lifting appliance cannot shake greatly due to inertia, so that the positioning accuracy of the lifting appliance is improved. (3) Two industrial cameras which are arranged in a diagonal line manner can judge the position of the lifting appliance more accurately, and the positioning accuracy of the lifting appliance is improved.
