Description

Technical Field

[0001] The invention relates to a double-vehicle anti-sway crossing type quay crane which is convenient for container alignment and belongs to the field of quay crane equipment. Background Art

[0002] The rapid development of the world economy has driven the rapid development of shipping logistics, and the global container throughput has continued to grow. In order to reduce transportation costs, container ships continue to develop towards larger sizes, and 3E-class container ships with a capacity of 22,000 TEUs have been put into use, requiring ports to have higher loading and unloading efficiency. When facing large container ships, the method of increasing the number of quay crane operations is often used to improve the loading and unloading efficiency on board. However, due to the operating spacing of quay cranes, simply increasing the number of quay crane operations can no longer meet the shipping customers' demand for ship-time efficiency, and a new type of quay crane needs to be developed.

[0003] At the same time, as a key loading and unloading equipment of container terminals, container quay cranes directly operate on ships and container trucks. The efficiency of quay crane loading and unloading greatly affects the overall loading and unloading efficiency of the terminal. When the quay crane operates on a container truck, due to the high height of the current quay crane trolley and the long distance between the container truck and the trolley, the hoist is prone to shaking when it is hanging the container down, making it difficult to align the container with the container truck, which greatly increases the difficulty of the quay crane driver. At this time, the driver needs to rely on his experience and move the quay crane trolley multiple times to complete the container alignment, which seriously affects the efficiency of the quay crane loading and unloading.

[0004] As the lifting height of the quay crane increases, the spreader or container is more likely to sway significantly under the influence of the sea breeze on the shore, which will have a serious impact on the alignment of the spreader or container. Therefore, this also puts higher requirements on the anti-sway technology of the quay crane. There are some problems with the current anti-sway technology. The anti-sway effect of mechanical anti-sway technology is not good, and the electronic anti-sway technology requires frequent changes in the length of the rope. In addition, the trolley motor will produce a certain amount of friction during operation. Therefore, in actual applications, the trolley speed is adjusted too frequently, which makes the driver uncomfortable. As a result, some container cranes equipped with electronic anti-sway systems were later dismantled. In order to improve performance, traditional control theory has become very complicated, which has greatly increased the initial investment and maintenance costs of control equipment and reduced the reliability of the system. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a through-type double-trolley quay crane, which has high operating efficiency compared with traditional single-trolley quay cranes, can greatly improve the loading and unloading efficiency of quay crane containers, can effectively prevent the shaking of the spreader, and make the spreader or container more quickly aligned, and the overall operating efficiency of the quay crane is high.

[0042] Working principle of the present invention:

[0043] According to research, the shaking of the quay crane spreader is periodic, swinging like a sine function. If the swing period of the spreader is destroyed, the amplitude of the swing will quickly decay to zero. The spreader anti-sway system of the present invention reduces the amplitude of the spreader shaking by destroying the spreader swing period, thereby realizing the spreader anti-sway function.

[0044] The anti-sway system 5 on the double-car anti-sway through-type quay crane for container handling of the present invention is composed of a first anti-sway device 29, a second anti-sway device 30 and a third anti-sway device 31. The first anti-sway device 29 is used to prevent the sling from shaking in the direction of the quay crane trolley, and the second anti-sway device 30 and the third anti-sway device 31 are also used to prevent the sling from shaking in the direction of the quay crane trolley.

[0045] In the first anti-sway device 29, the first section of the wire rope wound on the first drum 32 is used, and the first section of the wire rope is diverted through the first diverting pulley block 33 and connected to one side of the sling 35. The tail section of the wire rope is diverted through the first diverting pulley block 33 and connected to the other side of the sling 35. The first section and the tail section of the wire rope wound on the first drum 32 are connected to the sling 35 in a cross structure after being diverted. The use of this cross structure connection method can increase the angle and generate a greater lateral force to achieve the purpose of reducing shaking. When the sling 35 shakes in the direction of the trolley, the second motor 34 rotates in the corresponding direction, driving the first drum 32 connected to the second motor 34, so that the wire rope wound on the first drum 32 will pull the sling 35, thereby destroying the swing cycle of the sling 35 and achieving the purpose of reducing shaking. In the second anti-sway device 30, the third motor 36 drives the second drum 38 and the third drum 39 to adjust the tension of the steel wire rope 14 wound on the second drum 38 and the third drum 39, and the third motor 36 controls the pitch angle of the rocker device 41 to control the angle between the steel wire rope 14 wound on the second drum 38 and the third drum 39 to adjust the horizontal force component. In the third anti-sway device 31, two fourth motors 36 are symmetrically distributed on both sides of the quay crane trolley, and the two fourth motors 36 are connected by a coupling 42 to ensure the synchronous operation of the two fourth motors 36. The first section of the steel wire rope wound on the fourth drum 43 is connected to the sling 35 after being turned by the third steering pulley block 45 and the C pulley 49 at one end of the first rocker arm 50, and the tail section of the steel wire rope wound on the fourth drum 43 is connected to the sling 31 after being turned by the third steering pulley block 45 and the C pulley 27 at the end of the second rocker arm 51. The rocker arm device 41 and the third anti-sway device 31 cooperate with each other to achieve anti-sway of the sling 35 in the moving direction of the trolley.

[0046] The container alignment operation of the present invention: when the quay crane lifts the container from the ship to load and unload the container onto the container truck, the container truck arrives at the designated lane, and the alignment device 4 also moves above the lane where the container truck is parked, and places the hollow alignment area above the container truck. When the sling 35 approaches the alignment device 4 with the container sling, the container first collides with the guide limit device 14, and the rubber cushion layer 23 arranged on the guide plate 22 absorbs most of the impact energy of the container, and then the container enters the hollow alignment area 21 with the inclination angle of the guide plate 22, so that the container is aligned with the position of the container truck, and the sling 35 continues to descend with the container, and finally the sling 35 also descends through the hollow alignment area 21, when the sling 35 descends to the point where the ends on both sides of the sling 35 contact the baffle 26 of the telescopic device 15, and as the sling 35 continues to descend, the telescopic frame 25 of the telescopic device 15 is extended with it. Because of the telescopic device 15, the container is restricted in the running direction of the container aligning device 4 and will not shake. At the same time, the shaking in the running direction of the truck is greatly reduced due to the friction generated by the contact between the spreader 35 and the baffle 26. In this way, the container and the container truck can be aligned quickly and accurately, greatly improving the efficiency of the alignment. After the alignment is completed, the spreader 35 is retracted, and the first electrode 13 controls the telescopic device 15 to retract the telescopic frame 25.
