With the global economic integration and trade proliferation, improving the loading and unloading efficiency of a field bridge, especially the efficiency of a main hoisting mechanism, is one of the problems prioritized by designers and port managers.
The steel wire rope winding system of the main hoisting mechanism generally comprises an eight-rope winding system, a four-rope winding system, a full-function winding system and the like. The trolley in the eight-rope winding system is heavy in dead weight, high in requirement on wheel pressure and high in energy consumption, and has good anti-shaking effect. The four-rope winding system mechanism is simple in arrangement, light in dead weight, poor in anti-shake effect of the trolley, and poor in driver comfort level due to the fact that a special mechanical anti-shake mechanism or an electronic anti-shake device is required to be equipped for improving the anti-shake effect. The trolley in the full-function winding system has strong functions, but special auxiliary control mechanisms are required to be configured, and the control requirement is high.

Unlike the prior art, the following are:
preferably, the left end and the right end of the upper hanger frame 4 are connected with a pair of pulleys 5 which are arranged in mirror symmetry, and an included angle smaller than or equal to 90 degrees is formed between the plane where each pulley 5 is positioned and the longitudinal center line 7 of the upper hanger frame 1.
Preferably, the winding drum 3 is in a single winding drum form, four rope grooves are formed in the winding drum 3, steel wire ropes 8 are respectively stored in the rope grooves, one end of each steel wire rope 8 is fixed on the winding drum 3, the other ends of the two steel wire ropes 8 vertically and downwards penetrate through two corresponding pulleys 5 on the right end part of the upper hanger frame 4 respectively, and then are connected with the trolley structure 1 in a diagonal manner, the other ends of the other two steel wire ropes 8 are led out from the bottom of the winding drum 3, pass through a turning pulley 2 on the trolley structure 1, downwards penetrate through two corresponding pulleys 5 on the left end part of the upper hanger frame 4, and are also connected with the trolley structure 1 in a diagonal manner.
Preferably, the two end mirror symmetry sets up pulley 5 about the hoist upper bracket 4, and pulley 5 is less than 90 contained angles with cart or dolly (i.e. transverse center line 10/longitudinal center line 7) direction of operation, causes hoist upper bracket 4 swing when cart or dolly is operated, wire rope 8 is connected with hoist upper bracket 4 and forms certain contained angle, produces the component in cart or dolly direction to the pulling force that hoist upper bracket 4 formed, and the component that wire rope 8 produced on the left and right/front and back is the opposite offset, thereby reduces hoist upper bracket 4's swing, plays the anti-shake effect.
Preferably, each pulley 5 at two ends of the upper frame 4 of the lifting appliance is also connected with a transmission device 9, and as the upper frame 4 of the lifting appliance swings and swings, the two pulleys 5 at the same side of the upper frame 4 of the lifting appliance are respectively added with a transmission device 9 consisting of a gear or a plurality of gears, the two groups of gear transmission devices 9 are meshed, and the trend of the same-direction movement of the two pulleys 5 can be counteracted through reasonable arrangement of the number of the gears, so that the anti-swing performance is improved.
As shown in fig. 4, gears 9 are added on the pulleys 5 on the same side of the upper hanger frame 4, the two gears 9 are meshed, and according to the gear transmission characteristics, the transmission directions of the two pulleys 5 in the transmission chain are opposite. When the upper hanger frame 4 is in lifting process, the two pulleys 5 are required to rotate in opposite directions (as shown by arrow directions in fig. 4), and the gear transmission has no influence on lifting of the upper hanger frame 4.
As shown in fig. 5, when the upper frame 4 of the lifting appliance shakes, the two pulleys 5 along the shaking direction have the same rotation trend (as shown by the hollow arrow direction in fig. 5), and the newly added two gears drive the gears 9 to be consistent with the rotation direction of the two pulleys 5, so that the meshing position of the two gears 9 has the opposite direction (as shown by the solid arrow direction in fig. 5). The trend of the same-direction rotation of the pulley 5 in the shaking process is counteracted with the reverse rotation trend caused by gear transmission, the pulley 5 is guaranteed to be in a stable and non-rotating state in the shaking process, the friction force between the steel wire rope 8 and the rope groove on the pulley 5 changes the connection between the steel wire rope 8 and the lifting appliance upper frame 4 into a fixed point, the pulley 5 is locked by utilizing the reverse trend of the meshing position of the two gears 9, and the anti-shaking effect is greatly improved.
As shown in fig. 6, in the second embodiment of the four-rope winding hanger upper frame suitable for the main hoisting mechanism of the field bridge equipment provided by the invention, the winding drums 3 are in a double-winding drum form, and comprise a pair of winding drums which are all positioned above the trolley structure 1 and respectively correspond to two end parts of the hanger upper frame 4, each winding drum 3 is provided with two steel wire ropes 8 which vertically and downwards penetrate through pulleys 5 on corresponding end parts of the hanger upper frame 4 respectively, and are connected with the trolley structure 1 in a diagonal manner.
