[0002] A stacker reclaimer is a highly efficient loading and unloading machine for continuous conveying that can both stack and reclaim materials in large dry bulk yards. The tail car is usually called the feeding car or the discharging car, straddles the main conveyor belt, and cooperates with the main machine to achieve the function of diverting and stacking materials. The tail car plays a crucial role in the transfer of materials from the ground belt to the cantilever belt of the stacker. There are various forms of tail cars, and the simplest classification method is to divide them into single-tail cars, double-tail cars, and triple-tail cars according to the quantity. The single-tail car has a fixed type and a lifting type. The existing lifting tail car is only supported by hydraulic cylinders, and the head of the tail car will drop after a period of time, thus damaging other structures or scratching other structures during the transformation process; secondly, usually the hydraulic cylinders are designed outside, and there are safety hazards during the lifting process of the equipment; in addition, there is a phenomenon of unstable shaking during the lifting process of the hydraulic cylinders, causing the main beam of the belt conveyor to shake, and easily causing damage to the tail car system and other problems.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative work shall fall within the protection scope of the utility model.
[0016] As Figure 1 shown, a lifting gantry for the tail car of a stacker-reclaimer includes a lower gantry, an upper gantry and a movable rod. A support plate is connected between the lower gantry and the upper gantry. The lower gantry includes two columns, a lower cross beam is connected between the middle positions of the two columns, and a bottom beam is connected between the bottom positions of the two columns. The upper gantry includes two inclined supports, and an upper cross beam is connected between the middle positions of the two inclined supports. A hydraulic cylinder is installed at the bottom inside the column, a linear bearing is installed on the inner side of the top of the column, the top of the hydraulic cylinder is connected to the movable rod, the movable rod passes through the linear bearing and is vertically welded and fixed to the support plate. Rollers are installed between the lower part of the movable rod and the inner wall of the column. A position sensor is also installed at the bottom of the support plate, a controller is installed on the bottom beam, and locking bolts are respectively installed on the left and right sides of the upper part of the column.
[0017] A cushion block is also installed in the middle of the bottom of the support plate.
[0018] A lifting device is also installed on the lower cross beam. A support rod is installed at the top of the lifting device, and the top of the support rod is movably connected to the cushion block.
