Rail type container portal crane lifting and rotating trolley

Abstract

The invention relates to a rail type container portal crane, in particular to a rail type container portal crane lifting and rotating trolley and belongs to the technical field of rail type container portal cranes. The rail type container portal crane lifting and rotating trolley comprises an upper trolley frame, a lower trolley frame, a lifting and rotating mechanism, a trolley traveling mechanism, a cab with a platform, a first end beam, a lifting mechanism and a second end beam. The middle portion of the upper trolley frame is connected with the lower trolley frame through the lifting and rotating mechanism. The first end beam and the second end beam are welded to the left end and the right end of the upper trolley frame correspondingly. The trolley traveling mechanism is arranged on the first end beam and the second end beam. The lower end of the lower trolley frame is connected with the cab with the platform. The rail type container portal crane lifting and rotating trolley can adapt to any placing angle of containers on a storage yard, and container lifting operation is convenient; the cab also rotates while rotating and lifting are conducted, so that the container lifting sight line of the cab is facilitated to a greater extent; and due to the fact that the lifting mechanism is arranged below the trolley, the arrangement space of the trolley is reduced, the wheelspan of the end beams of the trolley can be decreased, and the operation distance of the trolley is increased.

Description

technical field [0001] The invention relates to a rail-type container gantry crane, in particular to a rail-type container gantry crane lifting rotary trolley, which belongs to the technical field of rail-type container gantry cranes. Background technique [0002] In the prior art, the hoisting mechanism and driver's cab of rail-mounted container gantry cranes are generally installed on the trolley, which is a fixed structure installation form. It needs to rely on electric or hydraulic push rods to pull the hoisting wire rope to make the container spreader rotate at a certain angle. function, and the rotation angle is only ±5°, which is very limited. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, so as to provide a rail-mounted container gantry crane lifting rotary trolley, which can realize large-angle rotation, and can adapt to any angle at which containers are placed in the yard, so as to facilitate the op...
