Description

Technical Field

[0001] The utility model relates to the technical field of container hoisting, and more specifically to an eight-rope integrated electric telescopic empty container hoist. Background Art

[0002] Automated three-dimensional empty container warehouse is a way for port terminals to improve the container storage method in ports using automated three-dimensional warehouse technology. It can increase the storage capacity of containers within a limited area and improve the utilization rate of the yard. When lifting containers, due to the relatively low efficiency of traditional container lifting, there are certain restrictions on the lifting height and lifting energy consumption of the crane, which cannot meet the conventional lifting equipment telescopic action and shifting and rotating action, resulting in relatively low lifting efficiency. As for the weight of the container itself, the weight of the container is relatively fixed and relatively light, and it is impossible to work hard on the design. Therefore, it is necessary to design for the empty container warehouse and make changes in the lifting equipment design to reduce the weight of the lifting equipment itself and reduce the energy consumption of the whole machine.

[0018] The technical solution of the present invention is specifically described below in conjunction with the drawings in the specification. The detailed features and advantages of the present invention are described in detail in the specific implementation mode. The content is sufficient to enable any technical personnel in this field to understand the technical content of the present invention and implement it accordingly. According to the description, claims and drawings disclosed in this specification, technical personnel in this field can easily understand the relevant purposes and advantages of the present invention.

[0019] Figure 1 The front view of the eight-rope integrated electric telescopic empty box hoist of the utility model is shown; Figure 2 The utility model provides an eight-rope integrated electric telescopic empty box hoist. Figure 1 , Figure 2 As shown, it is applied to a crane of an empty container warehouse with eight ropes winding. The eight-rope integrated electric telescopic empty container hoist mainly consists of a main beam 1, a telescopic beam 2, a hanger assembly 3, a cable storage basket 4, an electrical system 5, a telescopic drive mechanism 6, a guide plate mechanism 7, and a pin transfer mechanism 8.

[0020] The bottom of the main beam 1 is an I-beam structure, and the two sides of the main beam 1 are attached with reinforcing ribs, and the tail of the telescopic beam 2 is installed on the reinforcing ribs; the telescopic drive mechanism 6 connects the telescopic beam 2 to the main beam 1 telescopically; the main beam 1 and the telescopic beam 2 are connected by the telescopic drive mechanism 6, so that the telescopic beam can be telescoped to adjust the lifting length. The main beam 1 is provided with a hanger assembly 3 and a cable storage frame 4. The hanger assembly 3 is pushed by a push rod. The hanger assembly 3 is connected to the crane wire rope, and the cable storage frame 4 is connected to the crane cable, which transmits the power and control signals on the crane to the spreader. As the crane drives the spreader to rise and fall, the cable storage frame 4 can realize the function of retracting and releasing the cable. The two ends of the telescopic beam 2 are provided with a guide plate mechanism 7 and a revolving pin mechanism 8. The guide plate mechanism 7 has a guiding structure to facilitate the spreader to fall on the container. As a key component for connecting the container, the revolving pin mechanism 8 can be locked on the corner fittings of the container to enable the spreader to lift the container. The electrical system 5 is electrically connected to the cable storage basket 4, the telescopic drive mechanism 6, the hanger assembly 3, the guide plate mechanism 7, and the revolving pin mechanism 8. The electrical system 5 can distribute the power and signals transmitted by the crane cable to various components.

[0021] Figure 3 The schematic diagram of the pulley winding of the eight-rope integrated telescopic empty box hoist of the utility model is shown. The steel wire rope 9 of the crane is connected to the midpoints of the four sides of the integrated electric telescopic empty box hoist 10 through the pulley 11 on the trolley. The hanger assembly 3 is equipped with four electric push rods, which are respectively connected to the eight steel wire ropes. Figure 3As shown. The four electric push rods include a first electric push rod 33 and a second electric push rod 34 located on the left and right sides of the main beam, and a third electric push rod 31 and a fourth electric push rod 32 located in the front and rear directions of the main beam; the first electric push rod 33, the second electric push rod 34, the third electric push rod 31 and the fourth electric push rod 32 are electrically connected to the electrical system 5 respectively. The combination of the electric push rods moving in different directions can realize the translation and rotation of the integrated hoist. Press the reset switch of the console to reset the hoist. The first electric push rod 33 and the second electric push rod 34 extend and retract in the same direction, and the hoist moves in the direction of the trolley. At the same time, they move in and out in the opposite direction, and the eight-rope integrated electric telescopic empty box hoist makes a rotational movement. The third electric push rod 31 and the fourth electric push rod 32 extend and retract in the same direction, and the eight-rope integrated electric telescopic empty box hoist moves in the direction of the trolley.

[0022] When the eight-rope integrated electric telescopic empty container lifter needs to lift a container, the crane moves the eight-rope integrated electric telescopic empty container lifter to the upper part of the container, and the integrated electric telescopic empty container lifter 10 adjusts the spacing of the telescopic beams 2 through the telescopic drive mechanism 6 according to the length of the container, so that the pin rotation mechanism 8 can be aligned with the corner fittings of the container, and the integrated electric telescopic empty container lifter 10 is lowered through the wire rope 9. If at this time, the wire rope 9 causes a certain range of misalignment between the integrated electric telescopic empty container lifter and the container, it can be adjusted through rotation or translation. After the adjustment is completed, the integrated electric telescopic empty container lifter 10 continues to descend, and is further guided by the guide plate mechanism 7, so that the pin rotation mechanism 8 is smoothly connected to the container, completing the action of lifting the container.
