Description
Technical Field
The invention relates to a double-vehicle anti-shake traversing type quay crane convenient for box alignment, and belongs to the field of quay crane equipment.
Background
The rapid development of world economy has driven the rapid development of shipping logistics and the throughput of containers in the world is continuously increasing. In order to reduce the transportation cost, the container ship is continuously developed to be large-sized, and a 3E-class container ship with a loading capacity of 22000TEU is put into use, so that higher loading and unloading efficiency of ports is required. When facing large container ships, the mode of increasing the operation quantity of the shore bridges is adopted to improve the loading and unloading efficiency when the ships are in the face of the large container ships, and the operation space of the shore bridges is limited, so that the simple increase of the operation quantity of the shore bridges can not meet the demand of shipping customers on the efficiency when the ships are in the face of the large container ships, and a novel shore bridge needs to be developed.
Meanwhile, the container quay bridge is used as a key loading and unloading device of the container quay, the ship and the truck are directly subjected to operation, and the loading and unloading efficiency of the quay bridge greatly influences the overall loading and unloading efficiency of the quay. When the shore bridge works on the collection card, as the height of the existing shore bridge trolley is high, the distance between the collection card and the trolley is long, and the lifting appliance easily shakes when the container falls down, so that the difficulty in box alignment between the container and the collection card is greatly increased, the operation difficulty of a shore bridge driver is greatly increased, the operation of the box alignment is finished by moving the shore bridge trolley for many times by the experience of the driver, and the loading and unloading efficiency of the shore bridge is seriously influenced.
Along with the increase of the lifting height of the quay crane, the lifting appliance or the container is easier to shake greatly under the influence of the coastal sea wind, and the alignment of the lifting appliance or the container can be seriously influenced. This also places higher demands on the roll reduction technology of the quay. The existing anti-rolling technology has some problems, the anti-rolling effect of the mechanical anti-rolling technology is poor, the electronic anti-rolling technology needs to change the length of a rope frequently, and a certain friction is generated in the running process of a trolley motor, so that the phenomenon that the running speed of the trolley is adjusted too frequently and a driver is uncomfortable occurs in practical application, and certain container cranes provided with the electronic anti-rolling system are removed later. In order to improve the performance, the conventional control theory becomes very complex, so that the initial investment and maintenance cost of the control equipment are greatly increased, and the reliability of the system is reduced.

The working principle of the invention is as follows:
According to the research that the swinging of the quay crane lifting appliance is periodic and swings like a sine function, if the swinging period of the lifting appliance is destroyed, the swinging amplitude is rapidly attenuated to zero. The lifting appliance anti-rolling system reduces the amplitude of the swing of the lifting appliance by destroying the swing period of the lifting appliance, thereby realizing the function of preventing the lifting appliance from rolling.
The invention provides a double-car anti-shake traversing type anti-shake system 5 on a quay crane, which is convenient for a box, and consists of a first anti-shake device 29, a second anti-shake device 30 and a third anti-shake device 31. The first anti-sway device 29 is used for preventing the sway of the lifting appliance in the direction of the crane trolley, and the second anti-sway device 30 and the third anti-sway device 31 are simultaneously used for preventing the sway of the lifting appliance in the direction of the crane trolley.
In the first anti-sway device 29, the first section of rope is connected with one side of the lifting appliance 35 after being diverted through the first diverting pulley block 33 by utilizing the first section of rope of the steel wire rope wound on the first winding drum 32, the tail section of rope of the steel wire rope is connected with the other side of the lifting appliance 35 after being diverted through the first diverting pulley block 33 in sequence, the first section of rope and the tail section of rope of the steel wire rope wound on the first winding drum 32 are connected on the lifting appliance 35 in a cross structure after being diverted, and the included angle can be increased by adopting the cross structure connection mode, so that larger side force is generated, and the purpose of reducing sway is achieved. When the lifting appliance 35 shakes in the direction of the cart, the second motor 34 rotates in the corresponding direction to drive the first winding drum 32 connected with the second motor 34, so that the lifting appliance 35 can be pulled by a steel wire rope wound on the first winding drum 32, the swinging period of the lifting appliance 35 is damaged, and the purpose of stabilizing the swing is achieved. In the second anti-sway device 30, the second drum 38 and the third drum 39 are driven by the third motor 36, so that the tension of the wire rope 14 wound on the second drum 38 and the third drum 39 is adjusted, and the pitch angle of the rocker arm device 41 is controlled by the third motor 36, so that the opening angle between the wire rope 14 wound on the second drum 38 and the third drum 39 is controlled, so that the horizontal component force is adjusted. In the third anti-rolling device 31, two fourth motors 36 are symmetrically distributed on two sides of the quay crane trolley, and the two fourth motors 36 are connected through a coupling 42 to ensure synchronous operation between the two fourth motors 36. The first section of the wire rope wound on the fourth reel 43 is connected with the lifting appliance 35 after being turned by the third turning pulley block 45 and turned by the C pulley 49 at one end of the first rocker arm 50, and the tail section of the wire rope wound on the fourth reel 43 is connected with the lifting appliance 31 after being turned by the third turning pulley block 45 and the C pulley 27 at the tail end of the second rocker arm 51. The rocker arm arrangement 41 and the third anti-sway device 31 cooperate together to achieve a roll reduction of the spreader 35 in the direction of movement of the trolley.
The container alignment operation of the present invention is that when the quay crane lifts a container from a ship to load and unload the container onto a container truck, the container truck arrives at a specified lane, the alignment device 4 also moves above the parking lane where the container truck is parked, and the hollow alignment area is placed above the container truck. When the lifting tool 35 lifts the container close to the container aligning device 4, the container firstly collides with the guiding limiting device 14, most of the collision energy of the container is absorbed through the rubber mat layer 23 arranged on the guide plate 22, then the container enters the hollow aligning area 21 along with the inclination angle of the guide plate 22, the container is aligned with the position of the container truck, the lifting tool 35 continuously descends with the container, finally the lifting tool 35 descends downwards through the hollow aligning area 21, when the lifting tool 35 descends to the position that the two side ends of the lifting tool 35 are contacted with the baffle plates 26 of the telescopic device 15, and the telescopic frame 25 of the telescopic device 15 is stretched along with the lifting tool 35 continuously descends. Because of the telescopic means 15, the container is restrained in the direction of travel of the container means 4 and is not subject to sway, while sway in the direction of travel of the cart is also greatly reduced by friction created by contact of the spreader 35 with the baffles 26. Thus, the container and the container truck can be aligned quickly and accurately, and the efficiency of alignment is greatly improved. After the alignment is completed, the spreader 35 is retracted, the first electrode 13 controls the telescopic device 15, and the telescopic frame 25 is retracted.
