Problems solved by technology

[0002] The trolley of the crane is mainly used to lift and move the goods. The existing traveling mechanism of the trolley cannot adapt well to the vertical deformation of the traveling track. When the traveling track of the trolley deforms in the vertical direction, it will cause the trolley The operation is unstable or the operating mechanism is impacted, resulting in rail gnawing, and considering the height of the guardrail installed on the outside of the crane walking platform, the installation height of the main girder of the crane usually cannot be too close to the top of the factory building, which is not conducive to maximum utilization. The factory building causes a lot of unnecessary waste and affects the maximum lifting height of the crane; therefore, it is very necessary to provide a portable electric trolley for the crane that has a simple structure, stable operation, and can effectively adapt to the vertical deformation of the trolley track

Abstract

The invention relates to a portable electric trolley of a crane, which includes a trolley frame, the trolley frame is composed of a left walking frame, a right walking frame and a supporting connecting rod, and a Crafted square steel, the upper surface of the trolley frame is provided with an outer rotor motor, and the two ends of the outer rotor motor are respectively provided with brakes. On the upper surface of the trolley frame, a V-shaped frame is arranged on the lower surface of the left walking frame and the right walking frame near the two ends. Mechanism, the walking mechanism is composed of the active traveling wheel and the driven traveling wheel, the active traveling wheel is connected with the motor through the reducer, and the two sides of the V-shaped frame between the left traveling frame and the right traveling frame and the traveling support are provided with spring damping and shock absorption device; the present invention has a simple structure and can effectively adapt to rail deformation.

Description

Technical field [0001] The invention belongs to the technical field of lifting, and specifically relates to an electric trolley, in particular to a portable electric trolley of a crane. Background technique [0002] The crane trolley is mainly used to realize the lifting and moving of goods. The traveling mechanism of the existing crane trolley cannot well adapt to the vertical deformation of the traveling track. When the trolley traveling track is deformed in the vertical direction, the trolley will be caused. The operation is unstable or the operating mechanism is impacted, resulting in the phenomenon of rail gnawing. In addition, considering the height of the guardrail installed on the outside of the crane platform, the installation height of the crane main beam is usually not too close to the top of the plant, which is not conducive to maximum utilization The factory building causes a lot of unnecessary waste and affects the maximum lifting height of the crane; therefore, it ...
