Embodiment 1

[0060] This embodiment provides a winding system for the upper and lower trolleys, which can be used in the cooperative use of the through-type double trolleys and the quay bridge. Specifically, the winding system is suitable for use in the following girder structures, such as Figure 7 and Figure 8 As shown, the girder structure includes a first girder s1 and a second girder s2 arranged in parallel; a first guide rail s3 and a second guide rail s4 are provided on the opposite inner sides of the first girder s1 and the second girder s2, so The first guide rail s3 and the second guide rail s4 jointly form a first guide rail structure supporting the operation of the upper trolley k40; the outside of the first beam s1 and the second beam s2 are provided with a third guide rail s5 and a second guide rail. The four guide rails s6, the third guide rail s5 and the fourth guide rail s6 jointly form the second guide rail structure supporting the operation of the lower trolley k70, wh...

Embodiment 2

[0091] This embodiment provides a winding system for upper and lower trolleys, which is a modification based on Embodiment 1. The difference from Embodiment 1 lies in 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 17 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

[0093]This embodiment provides an upper and lower trolley winding system, which is a deformation based on Embodiment 1 or 2. The difference between it and Embodiment 1 or 2 is that the second vertical winding system in the lifting and winding subsystem of the lower trolley The setting mode of reversing block of pulleys is different from embodiment 1 or 2. Specifically, in this embodiment, as Figure 18 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 ...

Abstract

In the upper and lower trolley winding system of the present invention, several first rollers are horizontally supported on the inner side of the girder structure through the first bracket structure, and several second idler rollers are horizontally supported on the outer side of the girder structure through the second bracket structure, so that The wire ropes of the hoisting and winding subsystem of the upper trolley and the wire ropes of the lifting and winding subsystem of the lower trolley are respectively supported on the inner and outer sides of the girder structure. When lifting and lowering the spreader, the wire ropes of the lifting and winding subsystem of the upper and lower trolleys are placed separately Working on the inside and outside of the girder will not interfere with each other, and the horizontal part of the first hoisting wire rope wound on the first driving drum is set on the second hoisting wire rope wound on the second driving drum. The inner side of the horizontal space surrounded by the horizontal part of the wire rope makes the hoisting and winding subsystem of the upper trolley and the hoisting and winding subsystem of the lower trolley do not interfere with each other, and the space is more compact.

Description

technical field [0001] The invention relates to an upper and lower trolley winding system for quay bridges, belonging 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 puts forward higher requirements for the throughput of my country's ports. Traditional loading and unloading quayside bridges have been difficult to meet the requirements. bridge improvements. [0003] The unloading process of the existing port container is mainly carried out by a single lifting trolley on the traditional quay crane. During the working process of the lifting trolley, it lifts the container from one end of the quay bridge to the collection truck at the othe...
