Problems solved by technology

[0005] For this reason, the technical problem to be solved by the present invention lies in the technical problems that the wheels, guide rails and girders of the lower trolley in the passing-through double trolley of the prior art are seriously worn during operation, the loading and unloading efficiency is low, and potential safety hazards are prone to occur. Provide a new type of trolley system that is beneficial to reduce wear, improve loading and unloading efficiency, and is less likely to cause safety hazards

Embodiment Construction

[0035] The following embodiments will be used to further illustrate the present invention with reference to the accompanying drawings.

[0036] Such as Figure 1-Figure 4 As shown, the new type of trolley system described in this embodiment includes a first traveling mechanism s12 that can walk along the first guide rail s5 installed on the quay crane girder s0, and can move along the first rail s5 installed on the quay crane girder s0. The second traveling mechanism s18 running on two guide rails s6, the rigid frame s7 that rigidly connects the first traveling mechanism s12 and the second traveling mechanism s18, and the spreader connected below the rigid frame s7; The rigid frame s7 has a structural space s8 for the upper trolley s14 to pass through, and the lower trolley s15 satisfies the following conditions: the stable moment ΣMs caused by the gravity of the lower trolley s15 is greater than the horizontal inertia of the lower trolley s15 The overturning moment of force ΣMo....

Abstract

The invention discloses a novel lower trolley system. The system comprises first and second traveling mechanisms capable of traveling along first and second guide rails installed on a shore bridge girder, a rigid frame for rigidly connecting the first and second traveling mechanisms and a lifting appliance, wherein the rigid frame has a structural space through which an upper trolley passes, and a lower trolley meets the following condition: the stabilizing moment sigmaMs caused by the gravity of the lower trolley is larger than the capsizing moment sigmaMo of the horizontal inertia force of the lower trolley. The first and second traveling mechanisms of the lower trolley are rigidly connected with the lifting appliance, and when the stabilizing moment sigmaMs is larger than the capsizing moment sigmaMo, the lower trolley travels stably. During movement of the lower trolley, the lifting appliance and containers cannot shake easily, the lower trolley can travel stably, and abrasion between the first and second traveling mechanisms and the shore bridge girder is reduced; stable traveling consumes lower power than shaking traveling, and the loading and unloading efficiency of a whole shore bridge system is improved; compared with shaking traveling, stable traveling has advantages that the safety is improved, and potential risks are fewer.

Description

Technical field [0001] The invention relates to a trolley used for container quay cranes, in particular to a new type of lower trolley system for container quay cranes, and belongs to the technical field of container quay cranes. Background technique [0002] In the prior art, the method of setting multiple trolleys in the container quay crane system to operate at the same time is often used to improve the loading and unloading efficiency of the container quay crane; and currently, the operation mode of the through double trolley is mostly adopted. [0003] For example, Chinese patent document CN101323415A discloses a cross-type double-carriage bridge crane, which includes a cart and a main beam arranged on the cart, and also includes: a first load trolley, the first load trolley includes a retrieval device, a left flap The frame and the right flap frame, the retrieval device is suspended on the left flap frame and the right flap frame through the lifting sling, and the lifting sli...
