Description
Technical field
The present invention relates to a kind of formula of passing through double trolley system for quayside container crane and the many cart systems of formula of passing through, belong to container handling technical field.
Background technology
In the prior art, adopt more mode that multiple dolly runs simultaneously is set in quayside container crane system to improve the dress rate of discharging of quayside container crane; And the operation scheme of formula double trolley is passed through in many employings at present.
As Chinese patent literature CN101323415A discloses a kind of crossing type double trolley bridge type crane, it comprises cart and is arranged on the girder on cart, also comprise: the first loading trolley, first loading trolley comprises load-engaging device, left lobe vehicle frame and right lobe vehicle frame, load-engaging device is hung by the hoist cable that hoists and is hung on left lobe vehicle frame and right lobe vehicle frame, and the upper surface of the load-engaging device of hoist hoist cable and first loading trolley of the first loading trolley surrounds a U-shaped space, left lobe vehicle frame is by the guide rail support be arranged on the left of girder, right lobe vehicle frame is by the guide rail support be arranged on the right side of girder, and second loading trolley, second loading trolley is comprised vehicle frame, is arranged on the swing type mechanism on vehicle frame and is suspended in the load-engaging device on the pivoting part in this swing type mechanism by the hoist cable that hoists, the track supporting the second loading trolley vehicle frame to be arranged on girder and between the guide rail of the left lobe vehicle frame of support first loading trolley and the guide rail of the right lobe vehicle frame of supporting the first loading trolley, the bearing of trend of all guide rails is parallel to each other, and the second loading trolley can pass from described U-shaped space.Namely in this patent documentation, first loading trolley and described second loading trolley can run simultaneously, wherein, in order to avoid interfering therebetween, second loading trolley is rotated by swing type mechanism, be be suspended in carrying apparatus below the second loading trolley and freight container to be walked by original transverse direction and just become longitudinal walking, to make load-engaging device and freight container with most minor face through the U-shaped space of dolly under the first load-carrying, realize the synchronized operation of the first loading trolley and the second loading trolley.
But the crossing type double trolley bridge type crane described in above-mentioned patent documentation, have the following disadvantages: 1) in order to avoid upper, interfere between lower dolly, could pass from described U-shaped space after the load-engaging device needs rotation of the first loading trolley, but in operational process, the hoist cable that hoists connecting the load-engaging device of the first loading trolley all easily shakes with the hoist cable that hoists of the load-engaging device being connected the second loading trolley, the size in the U-shaped space hoisted between hoist cable of the load-engaging device of connection second loading trolley is caused easily to change, even if still easily occur and the situation that the load-engaging device of described second loading trolley is interfered mutually after causing the load-engaging device of the first loading trolley to rotate, meanwhile, the rotation after thing got by the load-engaging device of the first loading trolley needs to consume comparatively macro-energy, and rotation can cause rocking further of the load-engaging device of the first loading trolley, affects the working stability of whole system, 2) when the first loading trolley drives the load-engaging device after capturing freight container to walk on girder, under the inertia loading of the first loading trolley and the effect of wind load, hoist load-engaging device below hoist cable and freight container easily shakes, and the length of the hoist cable that hoists is longer, more easily rock, and shaking amplitude is also larger, and then following problem can be caused: load-engaging device and freight container rock the wearing and tearing can accelerated between left and right lobe vehicle frame and corresponding guide rail in operational process, also cause certain damage to crossbeam, have impact on the operating efficiency of the first loading trolley, reduce the dress rate of discharging of hoisting crane to a certain extent, meanwhile, rock and load-engaging device and freight container generating portion may be caused to depart from, there is potential safety hazard.
