Problems solved by technology

The gantry crane has the characteristics of high site utilization rate, large operation range, wide adaptability, and strong versatility. It is widely used in port freight yards. Its metal structure is like a door-shaped frame. Two legs are installed under the main beam, which can be directly Walking on the track on the ground, the two ends of the main girder can have outrigger cantilever beams. The gantry cranes in the prior art can only walk on the established track on the plane. The existing gantry crane does not have a gantry crane specially used for walking on the ramp. When the conventional gantry crane is used on the ramp, it will be inclined and cannot be braked, which will affect the use. Therefore, it is necessary to provide a structure Simple, slope-operable, stable-running and easy-to-use ramp-running cranes are necessary

Abstract

The invention relates to a ramp running crane. The ramp running crane comprises a main beam, a left supporting leg, a right supporting leg and bottom beams, the left supporting leg and the right supporting leg are respectively mounted at two ends of the main beam, a sliding rail is arranged on the main beam, a lifting device is mounted on the sliding rail, the lifting device comprises a middle pulley, first motors and a reel, the reel is arranged at two sides of the middle pulley, the first motors are arranged at two sides of the reel, the reel is connected with wire ropes, and the two wire ropes are commonly connected with a suspender; and the shape of each of the left supporting leg and the right supporting leg is an inverted V shape, the bottom beams are arranged at the bottom ends of the left supporting leg and the right supporting leg, wheels are arranged at two ends of every bottom beam, the wheels are fixed by rotating shafts, every rotating shaft is provided with a brake, the output ends of second motors are hinged to the end parts of the rotating shafts, and the rotating shafts are connected with the output ends of the second motors through decelerators. The ramp running crane has the advantages of simple structure, running on a ramp, stable running structure, and convenience in use.

Description

technical field [0001] The invention belongs to the technical field of crane systems, and in particular relates to a ramp-running crane. Background technique [0002] Gantry crane is a deformation of bridge crane, also called gantry crane. It is mainly used for loading and unloading operations of outdoor cargo yards, stockyard cargoes, and bulk cargoes. The gantry crane has the characteristics of high site utilization rate, large operation range, wide adaptability, and strong versatility. It is widely used in port freight yards. Its metal structure is like a door-shaped frame. Two legs are installed under the main beam, which can be directly Walking on the track on the ground, the two ends of the main girder can have outrigger cantilever beams. The gantry cranes in the prior art can only walk on the established track on the plane. The existing gantry crane does not have a gantry crane specially used for walking on the ramp. When the conventional gantry crane is used on the...
