Problems solved by technology

In the prior art, the hoisting drive mechanism and anti-sway drive mechanism on the crane trolley are arranged in the middle of the beam of the trolley frame, causing the beam of the crane trolley to adopt a double I-shaped beam structure or a double box beam structure, resulting in an increase in the weight of the crane trolley ,Increased costs
At the same time, it is unavoidable to increase the self-weight deflection of the small frame beam
The weight of the lifting drive mechanism and the anti-sway driving mechanism is concentrated in the middle of the beam of the trolley frame, resulting in increased deflection in the middle of the beam, which is not conducive to the leveling and operation of the lifting drive mechanism
At the same time, it also increases the track wear on the driving mechanism of the trolley and the outrigger of the crane, making it difficult to walk

Abstract

The invention discloses a traveling crab and a crane. The traveling crab comprises a trolley frame, traveling driving mechanisms and lifting driving mechanisms; the traveling driving mechanisms are arranged at both end parts of the trolley frame and are used for driving the trolley frame to move; and the lifting driving mechanisms are arranged at both end parts of the trolley frame. The traveling crab has the advantages of simple structure, low cost, good stable performance and the like.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a crane trolley and a crane. Background technique [0002] At present, the crane trolley adopts a double I-beam structure or a double box beam structure, and the trolley frame is heavy. The hoisting drive mechanism and the anti-sway drive mechanism are arranged in the middle of the trolley frame beam, and the force condition of the trolley frame beam is not good, which increases the self-weight deflection of the trolley frame beam, which is not conducive to the leveling of the hoisting drive mechanism, increasing the Possibility of the trolley gnawing on the rail. The lifting drive mechanism adopts the arrangement of parallel shafts, and the space between the reel and the motor is small, which is inconvenient for maintenance. [0003] The main working mechanism of the port gantry crane is the trolley. The weight and layout of the crane trolley are very important, ...
