Abstract

A hydraulic portal crane comprises a portal frame structure. A cart walking device is arranged at the bottom of the portal frame structure. A cab is arranged in the middle of the portal frame structure. Oil cylinder jacking mechanisms are arranged on the two sides of the portal frame structure. A lifting appliance translation frame, a lifting appliance rotating frame and a lifting appliance turnover frame are arranged at the top of each oil cylinder jacking mechanism. Each lifting appliance turnover frame is hinged to the top of the corresponding oil cylinder jacking mechanism. The tops of the two lifting appliance turnover frames are connected through a sliding cross beam. The translation frames are arranged on the sliding cross beam. Each lifting appliance rotating frame is arranged below the corresponding lifting appliance translation frame and provided with a lock device. According to the hydraulic portal crane, all operation tasks of containers in a train freight transport yard can be completed, and for example, the containers can be unloaded from a train, can be mounted on a vehicle and can be placed on the ground to be stacked; the containers can be turned over by a certain angle, and loading and unloading of bulk materials are completed; and the hydraulic portal crane is small in size and small in weight.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, in particular to a hydraulic gantry crane. Background technique [0002] At present, the transportation volume of container railway logistics is increasing day by day, and the rail-mounted gantry cranes in the past can no longer meet the needs. Moreover, most of the small freight yards are not equipped with container cranes. The current railway freight market is in urgent need of a small and portable tire-type gantry container handler for instant loading, unloading and handling of various railway freight yards. [0003] So how to design a kind of small-sized and portable door-type container handling equipment becomes the problem demanding prompt solution in this field. Contents of the invention [0004] In view of this, the present invention aims to provide a small and portable door-type container handling equipment. [0005] In order to achieve the above object, technical solution of the ...
