The invention disclose a novel door type hoisting device. The device comprises a main beam, supporting legs, a sliding table, sliding table rails, a screw, a screw sliding block, a hosting unit screw base and a screw motor; the two ends of the main beam are horizontally and fixedly erected at the upper ends of two vertical supporting legs, the two sliding table rails are arranged below the main beam in a front-back parallel manner, the length direction of the sliding table rails is parallel to the length direction of the main beam, the two ends of the sliding table rails are fixedly connected with the inner sides of the two supporting legs, the two sides of the bottom of the sliding table are erected on the two sliding table rails in a sliding manner, a thread through hole is formed in the side wall of the screw sliding block, the bottom of the screw sliding block is fixedly arranged on the top of the sliding table, the screw is horizontally arranged above the sliding table through the screw base, the length direction of the screw is parallel to the length direction of the sliding table, the tail end of the screw is connected with the screw motor, and the screw is sleeved with the thread through hole in the screw sliding block. The hoisting device is simple and ingenious in structure, centrifugal brake is sufficiently used, the full brake process is purely mechanical, and the beneficial effects of being high in reliability, rapid in brake and the like are achieved.
Description
technical field [0001] The invention belongs to the field of cranes, in particular to a gantry lifting device and method. 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. Its metal structure is like a door-shaped frame. Two legs are installed under the main beam, which can directly walk on the track on the ground. The two ends of the main beam can have outrigger cantilever beams. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in port cargo yards; if the crane fails to lift heavy objects, its heavy objects may drop rapidly , causing danger. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a gantry lifting...
