Problems solved by technology

The most critical thing is how to arrange the driving mechanisms of the two hoisting trolleys, namely the hoisting mechanism, the traveling mechanism and the wire rope winding system, so that the two trolleys do not interfere with each other during work; at the same time, the outreach of the boom of the quay crane reaches 80 meters , the wire rope of the hoisting mechanism hangs too long, if there is no suitable tow rope system, the hoisting wire ropes of the two trolleys are in a hanging state, and it is very easy to entangle with each other and cause an accident

Embodiment 1

[0091] This embodiment provides a double-trolley driving mechanism for use on a quay bridge with double trolleys. The double trolley driving mechanism includes a double trolley lifting mechanism, a double trolley traction mechanism and a double trolley winding system. Wherein, the double trolley lifting mechanism includes an upper trolley lifting mechanism b1 for driving the upper trolley to lift or land and a lower trolley lifting mechanism b2 for driving the lower trolley to lift or land; the double trolley traction mechanism It includes the upper trolley traction mechanism c1 for driving the upper trolley to move forward and backward horizontally and the lower trolley traction mechanism c2 for driving the lower trolley to move forward and backward horizontally; the double trolley winding system is connected to the double trolley lifting mechanism and the double trolley traction mechanism, the double-trolley winding system can drive the double-trolley spreader to lift or lan...

Embodiment 2

[0124] This embodiment provides a double-trolley winding system, which is a deformation based on Embodiment 1. It differs from Embodiment 1 in that the arrangement and implementation of the third pulley block in the lifting and winding subsystem of the upper trolley Example 1 is different. Specifically, in this embodiment, as Figure 10 As shown, the third pulley set includes the fourteenth pulley k163 located at the upper part of the upper spreader k60, the fifteenth pulley k164 located at the lower part of the upper spreader k60, and the extension of the first hoisting wire rope k11 from the first horizontal pulley k161. The outlet goes around the fourteenth pulley k163 from the top, then goes around the fourteenth pulley k163 from the bottom of the fifteenth pulley k164 and goes out from the fourteenth pulley 163, and finally is arranged on the bottom of the upper spreader k60.

Embodiment 3

[0126] This embodiment provides a double trolley winding system, which is a modification based on Embodiment 1 or 2. The difference between it and Embodiment 1 or 2 is that the second vertical The setting mode of reversing block of pulleys is different from embodiment 1 or 2. Specifically, in this embodiment, as Figure 11 As shown, the second vertical redirecting pulley block k26 includes two fourth horizontal pulleys k261 and fifth vertical pulleys k262 arranged at a certain distance on the top of the lower trolley k70, and the sixth pulley k267 arranged on the lower trolley k70 , several parallel seventh pulleys k263 arranged on the upper part of the lower spreader k80, several parallel eighth pulleys k264 arranged on the upper part of the lower spreader k80, and the first pulley k264 arranged on the bottom of the lower spreader k80 Nine pulleys k265, the fifth vertical pulley k262 is farther away from the second horizontal diverting pulley group k24 than the fourth horizo...

Abstract

The invention discloses a double-trolley drive mechanism used for a traversing type double-trolley quay crane. The double-trolley drive mechanism comprises double trolley lifting mechanisms, double trolley traction mechanisms and double trolley winding systems, wherein the double trolley winding systems comprise an upper trolley winding subsystem, a lower trolley winding subsystem, an upper trolley lifting and winding subsystem and a lower trolley lifting and winding subsystem; the upper trolley lifting and winding subsystem comprises at least one first drive winding drum, at least one first lifting steel rope which is wound on the first drive winding drum and a plurality of first carrier rollers which are used for horizontally supporting the first lifting steel rope; the first carrier rollers are horizontally supported on the inner side of a girder structure by a first bracket structure; a plurality of second carrier rollers are horizontally supported on the outer side of the girder structure by a second bracket structure; and horizontal parts of the first drive winding drum and the first lifting steel rope are arranged on the inner side of a horizontal space which is formed by a horizontal part of a second lifting steel rope in an enclosing way.

Description

technical field [0001] The invention relates to a through-type double-car quay bridge, in particular to a double-car driving mechanism for a through-type double-car quay bridge, and belongs to the technical field of heavy object lifting. Background technique [0002] The quay crane is the main loading and unloading tool used in the port, and the quay crane plays a very important role in the container loading and unloading process of the port. Since my country's accession to the World Trade Organization, my country's import and export trade has also continued to increase, which has put forward higher requirements for the throughput of my country's ports. Traditional loading and unloading quayside bridges have been difficult to meet the requirements. Therefore, container The quay bridge is improved. [0003] During the unloading process of traditional port containers, the container is lifted by a single lifting trolley on the traditional quay crane, and the lifting trolley lif...
