Horizontal mast assembly

Abstract

The invention relates to a horizontal mast assembly, and belongs to the technical field of special vehicle manufacturing. The horizontal mast assembly is composed of a longitudinal roller frame and atransverse guide rail framework, the transverse guide rail framework is welded on a roller frame of the longitudinal roller framework, the longitudinal roller framework is composed of the roller frame, guide rollers and reinforcing plates, the roller frame is longitudinally and symmetrically arranged, the guide rollers are fixedly arranged at the two ends of the roller frame correspondingly, and amounting seat for a piston rod of a hydraulic oil cylinder is arranged between the reinforcing plates; and the transverse guide rail framework is composed of horizontal mast guide rails, cross beamsand interval partition plates, and the horizontal mast guide rails are symmetrically welded on the roller frame in a front-back symmetry mode. The horizontal mast assembly is horizontally arranged ona vehicle auxiliary frame, a movable platform is installed in the horizontal mast guide rails of the transverse guide rail framework according to needs, and a working accessory installed on the movable platform can transversely move in the horizontal mast guide rails, so that the transverse and longitudinal linkage operation in the horizontal plane is realized, moreover, the center of gravity of cargoes is in the plane of the vehicle frame, then overturning of a vehicle can be effectively reduced, and the operation safety coefficient is improved.

Description

technical field [0001] The invention relates to a horizontal mast assembly, which belongs to the technical field of special vehicle manufacturing. Background technique [0002] The mast is the most important lifting device of the forklift. The horizontal dimension (i.e. width) of the mast is determined by the layout (i.e. the inner distance between the front wheels of the forklift and the necessary clearance), and its width must be smaller than the front wheel base. It needs to be balanced by the weight of other parts of the forklift, so as not to overturn forward. In order to fork the goods, the forklift mast must be located in front of the wheels, otherwise the goods will interfere with the wheels. The mast is usually installed vertically, using part of the bearing bush and Frame connection, during use, due to the unbalanced load of the goods, the deviation between the cargo center and its geometric center, and the uneven road surface, the forklift will be unbalanced.

The horizontal dimension (i.e. width) of the mast is determined by the layout (i.e. the inner distance between the front wheels of the forklift and the necessary clearance), and its width must be smaller than the front wheel base. It needs to be balanced by the weight of other parts of the forklift, so as not to overturn forward. In order to fork the goods, the forklift mast must be located in front of the wheels, otherwise the goods will interfere with the wheels. The mast is usually installed vertically, using part of the bearing bush and Frame connection, during use, due to the unbalanced load of the goods, the deviation between the cargo center and its geometric center, and the uneven road surface, the forklift will be unbalanced. The goods are easily dislocated and slipped during loading, unloading and transportation, resulting in damage to the goods and safety accidents. Seriously, it may cause personal injury
