Problems solved by technology

The driving part of this kind of trolley running mechanism has many components and its structure is relatively complicated. The layout space of the trolley of the container gantry crane is limited, and this set of drives takes up a lot of space, making the maintenance space narrow. The traditional trolley The operating mechanism mainly has the following disadvantages:
[0003] 1. Since the running mechanism of the trolley needs to start and brake frequently, the performance requirements for the reducer are relatively high, and the daily maintenance of the reducer is relatively frequent, which is quite troublesome and inconvenient
Especially in the cold areas in northern my country, it is a lot of work to replace all the lubricating oil of the reducer
[0004] 2. The brake is arranged on the high-speed shaft. If the reducer is in poor operating condition during braking, the "brake" will fail, and the safety is low.

Embodiment Construction

[0021] After a lot of market research and technical analysis, we found that the measure that can fundamentally solve the above shortcomings of the traditional trolley running mechanism is how to improve the driving mechanism of the trolley. mechanism. With the continuous advancement of motor technology, motor manufacturers have now developed multi-pole motors. The number of poles of the multi-pole motor has reached 60 poles, its synchronous speed has reached 100 rpm, and the output torque of the corresponding motor has been significantly improved. Generally, the speed of the trolley running mechanism of the container gantry crane is not fast, about 70m / min; the torque value transmitted by the mechanism is not large. Based on these conditions and reasons, we have done a lot of design and experiments to configure the multi-pole motor in the trolley running mechanism. The specific structure is described as follows:

[0022] Referring to Fig. 2 and Fig. 3, the trolley running m...

Abstract

A carriage running mechanism for hoister is composed of a multi-stage motor, two shaft couplings connected respectively to the high-speed terminal and low-speed terminal of said multi-stage motor, two floating axles with one end connected respectively with another ends of said shaft couplings and another end linked with the gear in gear-rack bar mechanism, two bearings, and a brake.

Description

technical field [0001] The invention relates to a container crane, in particular to a trolley running mechanism of a container gantry crane. Background technique [0002] At present, the trolley running mechanism of the container gantry crane mainly has the form of rack and pinion drive and direct drive four-wheel (four-wheel drive), of which the four-wheel drive also includes three-in-one drive. The mechanism composition of these two types of trolley drive includes: motor, coupling, brake, reducer, and then drive the gear or drive the four wheels of the trolley through the universal joint or the connection method of the shaft sleeve and the floating shaft. The trolley running mechanism driven by rack and pinion is shown in FIG. 1 , which includes a motor 81 , a brake 82 , a reducer 83 , and a shaft coupling 84 , and the gears are driven by a floating shaft 85 . The driving part of this kind of trolley running mechanism has many components and its structure is relatively co...
