Description

Technical Field

[0001] The invention relates to the technical field of crane spreaders, and in particular to a crane spreader used in a port. Background Art

[0002] With the acceleration of global economic integration, international trade has shown an explosive growth trend. As the core mode of transportation that undertakes more than 90% of the world's cross-border freight volume, the shipping industry is facing unprecedented development opportunities. Against the background of the continuous increase in container throughput, port operation efficiency has become a key bottleneck restricting the smooth flow of logistics supply chain. As the core hub connecting ships and land transportation, container terminals bear the heavy task of handling tens of thousands of standard containers per day, and hoisting operations are the most core link, and their automation and intelligence level directly affects the operating efficiency of the entire port.

[0003] In the current container handling system, crane spreaders are key equipment that directly acts on the container, and their operation mode is still highly dependent on manual intervention. The traditional spreader system requires the operator to visually determine the position of the container lock hole and manually adjust the spreader torsion angle and telescopic distance. This semi-automatic operation mode has three core pain points: First, the average manual alignment process takes a long time, which is very likely to cause congestion at the terminal berth during the concentrated berthing of large container ships; second, the operator needs to maintain high-intensity mental concentration for a long time, and the alignment deviation rate caused by visual errors is high when operating in bad weather or at night; third, there are major safety hazards in the manual intervention link; this traditional operation mode has formed a significant contradiction with the needs of smart port construction. Summary of the invention

[0004] In view of the above problems, the present invention provides a crane spreader for use in ports to solve the problem that the existing spreader cannot be automatically aligned.

[0005] The technical scheme used in the present invention is: a crane spreader used in a port, comprising a frame mechanism, a connecting mechanism, a fixed clamping mechanism, a vertical positioning mechanism and a horizontal positioning mechanism; the horizontal positioning mechanism comprises a connecting frame II fixedly mounted on the frame mechanism, a positioning clamping rod placed in the middle of the connecting frame II, a plug connecting the connecting frame II with the positioning clamping rod, a positioning slide bar I slidably mounted in a slide groove provided at the lower end of the positioning clamping rod, a slide bar II slidably mounted in a slide groove provided at the lower end of the positioning slide bar I, a horizontal positioning roller rotatably mounted in a groove provided under the slide bar II and connected to a motor, and a wire wheel connected to the motor and wound with a steel wire rope connected to the positioning slide bar I; The vertical positioning mechanism includes a hydraulic cylinder I whose end of a hydraulic rod contacts the side of a positioning clamp rod, a turning frame I rotatably mounted on an axis provided on both sides of the lower end of the positioning slide rod I, a vertical positioning roller I rotatably mounted in a groove provided on the lower end surface of the turning frame I, a coil spring connecting the turning frame I and the positioning slide rod I to drive the turning frame I to turn, a turning frame II rotatably mounted in a groove provided on the side of the positioning clamp rod, a vertical positioning roller II rotatably mounted in a groove provided on the lower end surface of the turning frame II, a rotating cylinder fixedly mounted on an axis connected to the turning frame II and the positioning clamp rod, a limiting clamp fixedly mounted in the fixed clamping mechanism, and a positioning slide rod II slidably mounted with the limiting clamp.

[0007] Preferably, the fixed clamping mechanism includes a clamping plate frame with connecting sliding shafts fixedly installed on both sides, a clamping plate rotatably installed with the shaft and the clamping plate frame, a push rod rotatably installed with the upper end of the clamping plate through a rotating connecting block, and a hydraulic cylinder II that pushes the two push rods to move in opposite directions.

[0008] Preferably, the frame mechanism includes a lower frame rotatably mounted with a rotating shaft, four corner blocks fixedly mounted at the four corners of the lower frame, an upper frame arranged above the lower frame, a transverse steel frame fixedly mounted at the upper end of the upper frame, a plurality of hydraulic fixing frames fixedly mounted on the transverse steel frame, and a plurality of connecting frames I fixedly mounted on the lower frame and the upper frame.

[0009] Preferably, steel wire ropes are installed on the connecting frame I, and the ends of the steel wire ropes are connected together and connected to the crane.

[0010] Preferably, there are two fixed clamping mechanisms arranged in a mirror-symmetrical manner and respectively installed on both sides of the frame mechanism.

[0011] Preferably, there are multiple connecting mechanisms, and the two fixing mechanisms are connected to the frame mechanism to facilitate the fixing mechanisms to clamp the container.

[0012] Preferably, the insert connects the positioning clamp rod to the connecting frame II. After removing the insert, the positioning clamp rod can be separated from the connecting frame II, and the positioning slide bar II can be taken out from the limiting clamp. At this time, vertical positioning mechanisms and horizontal positioning mechanisms of different numbers and positions are installed on the frame device and the fixing device according to needs to adapt to different situations.

[0013] Beneficial effects of the present invention: 1.

In this way, the equipment can be automatically aligned with the container without the need for manual alignment, which is convenient for the subsequent process of the equipment clamping the container; 2. The horizontal positioning roller rotates and cooperates with the four slide bars II to align the two containers horizontally; the vertical positioning roller I rotates to make the two containers vertically until the two containers are vertically aligned. This allows the containers to be aligned and stacked during the container transportation process without the need for manual container alignment; 3. Connect the positioning clamp rod to the connecting frame II through the insert strip. After removing the insert strip, the positioning clamp rod and the connecting frame II can be separated, and the positioning slide bar II can be taken out from the limiting clamp. At this time, different numbers and positions of vertical positioning mechanisms and horizontal positioning mechanisms can be installed on the frame device and the fixing device according to the needs to adapt to different situations; 4. The fixed clamping mechanism is connected to the frame mechanism through the connecting mechanism, so that when the fixed clamping mechanism fails, the fixed clamping mechanism can be quickly replaced without replacing the entire sling, saving time. A single sling is equipped with multiple fixed clamping mechanisms, avoiding the problem of replacing the entire sling after the fixed clamping mechanism fails. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the vertical positioning roller Ⅰ18 is connected to the motor, and the motor is fixedly connected to the turning frame Ⅰ17. The motor drives the vertical positioning roller Ⅰ18 to rotate, so that the vertical positioning roller Ⅰ18 rotates on the container provided below, so that the device and the container clamped by the device are vertically aligned with the container placed below, until the container placed below is completely in contact with the side of the positioning slide bar Ⅱ31, so that the two containers are aligned through the positioning slide bar Ⅱ31; the turning frame Ⅱ22 is rotatably installed on the side of the positioning clamping rod 14 In some grooves, a rotating cylinder 24 is fixedly installed at one end of the shaft connecting the turning frame Ⅱ 22 and the positioning clamp rod 14, and the rotating cylinder 24 is fixedly installed on the positioning clamp rod 14; a groove is provided on the lower end surface of the turning frame Ⅱ 22, and a vertical positioning roller Ⅱ 23 is rotatably installed in the groove, and the shaft of the vertical positioning roller Ⅱ 23 is connected to the motor, and the motor is fixedly connected to the turning frame Ⅱ 22, and the motor drives the vertical positioning roller Ⅱ 23 to rotate; so that the vertical positioning roller Ⅱ 23 rotates on the container, and then drives the device to move vertically relative to the container so that the device is vertically aligned relative to the container; until the container and the side of the positioning slide bar Ⅱ 31 are completely aligned After full contact, the container and the device are aligned through the positioning slide bar Ⅱ31; the limiting clamp 27 is fixedly installed on the side of the clamping plate frame 25, and two limiting clamps 27 are provided on one clamping plate frame 25; the positioning slide bar Ⅱ31 is slidably installed in the limiting clamp 27 and can slide in the limiting clamp 27; when the crane puts the device on the container, the positioning slide bar Ⅱ31 contacts the container, and the container pushes the positioning slide bar Ⅱ31 to move upward under the restriction of the limiting clamp 27, and after the positioning slide bar Ⅱ31 does not contact the container, the positioning slide bar Ⅱ31 slides down and is outside the container, and at this time the motor drives the vertical positioning roller Ⅱ23 to rotate;Thus, the vertical positioning roller Ⅱ23 rotates on the container, and then drives the device to move vertically relative to the container so that the device is vertically aligned relative to the container.

[0037] Implementation example Figure 5-Figure 8As shown, the lateral positioning mechanism includes: a connecting frame II 12, an inserting strip 13, a positioning clamping rod 14, a wire wheel 15, a positioning slide rod I 16, a slide rod II 19, and a lateral positioning roller 20; the connecting frame II 12 is fixedly installed on the lower frame 1, and a positioning clamping rod 14 can be placed in the middle of the connecting frame II 12. After the positioning clamping rod 14 is placed in the middle of the connecting frame II 12, the inserting strip 13 is inserted into the connecting hole of the connecting frame II 12 and the connecting hole provided on the positioning clamping rod 14 to connect the connecting frame II 12 and the positioning clamping rod 14; the lower end of the positioning clamping rod 14 is provided with a slide groove, and the inside of the slide groove A positioning slide bar Ⅰ16 is slidably installed, and a slide groove is provided at the lower end of the positioning slide bar Ⅰ16. A slide bar Ⅱ19 is slidably installed in the slide groove. A spring is provided on the slide bar Ⅱ19, and the spring connects the slide bar Ⅱ19 and the positioning slide bar Ⅰ16. A groove is provided under the slide bar Ⅱ19, and a transverse positioning roller 20 is rotatably installed in the groove. One end of the transverse positioning roller 20 is provided with an axis and is connected to the motor through a chain group. The motor is fixedly installed in the groove provided on the side of the slide bar Ⅱ19; a groove is provided on the upper part of the positioning clamping rod 14, and a wire wheel 15 is rotatably installed in the groove, and the wire wheel 15 is connected to the motor. Thus, the wire wheel 15 is driven to rotate by the motor; a wire rope is wound around the wire wheel 15, and the end of the wire rope is fixedly connected to the upper end of the positioning slide rod Ⅰ16; when the transverse positioning roller 20 contacts the upper end of the container placed below, the container pushes the transverse positioning roller 20 to drive the slide rod Ⅱ19 to move upward, compressing the spring provided on the slide rod Ⅱ19. At this time, the motor drives the transverse positioning roller 20 to rotate, and then drives the device and the container fixed in the device to move horizontally relative to the container placed below, until the compressed spring of the slide rod Ⅱ19 pops out At this time, the side of the slide bar Ⅱ19 contacts the container. At this time, the four slide bars Ⅱ19 align the device and the container fixed in the device and the container placed below in the horizontal direction; the positioning clamp rod 14 is connected to the connecting frame Ⅱ12 through the insertion strip 13. After removing the insertion strip 13, the positioning clamp rod 14 can be separated from the connecting frame Ⅱ12, and the positioning slide bar Ⅱ31 can be taken out from the limiting clamp 27. At this time, vertical positioning mechanisms and horizontal positioning mechanisms of different quantities and positions can be installed on the frame device and the fixing device according to needs to adapt to different situations.

[0038] Working principle: When the equipment is used to transport containers at the port, first install the two fixing mechanisms on both sides of the lower frame 1, insert the connecting slide shaft 26 into the slide hole provided at the lower end of the corner block 3, and then rotate the rotating shaft 4 through the handle provided on the rotating shaft 4, thereby driving the cam 5 to rotate, and then push the slide rod Ⅰ6 to move through the cam 5, and then drive the card block 7 to insert into the card groove provided on the outer wall of the connecting slide shaft 26 to connect the fixing mechanism with the corner block 3; then install different numbers of vertical positioning mechanisms and horizontal positioning mechanisms in different positions according to needs, and then connect the crane with the steel wire rope provided on the equipment, so that the crane can lift the frame mechanism in the equipment through the steel wire rope, and then lift the equipment; Then the hydraulic cylinder Ⅰ11 drives the positioning clamp rod 14 to flip, so that the positioning clamp rod 14 flips a certain angle relative to the connecting frame Ⅱ12. At this time, the equipment is moved to the top of the container by a crane, and then the equipment is lowered. At this time, the rotating cylinder 24 drives the flipping frame Ⅱ22 to flip, and flips the flipping frame Ⅱ22 out of the groove provided on the side of the positioning clamp rod 14. At this time, the vertical positioning roller Ⅱ23 is perpendicular to the upper end surface of the container. Then the equipment is lowered. After the inclined positioning clamp rod 14 contacts the container, the equipment is gradually moved to the container position for horizontal alignment. Then the vertical positioning roller Ⅱ23 contacts the upper end of the container, and then the vertical positioning roller Ⅱ23 is driven by the motor to rotate, so as to perform vertical alignment. After alignment, the positioning slide bar Ⅱ31 slides off the limiting clamp 27, and the lower end of the positioning slide bar Ⅱ31 exceeds the lower end of the container, which is convenient for aligning the two containers through the positioning slide bar Ⅱ31. After alignment, the hydraulic cylinder II 30 drives the clamping plate 28 to clamp and fix the container, so that the device is fixedly connected to the container. At this time, the crane lifts the device and the fixed container and transports them to the designated position. At this time, the motor connected to the wire wheel 15 rotates to drive the wire wheel 15 to rotate, thereby driving the positioning slide bar I 16 to move downward, until the positioning slide bar I 16 drives the turnover frame I 17 to move to a position beyond the container. The turnover frame I 17 rotates under the drive of the coil spring 21, so that there is a certain distance between the upper end of the turnover frame I 17 and the lower end of the container. At this time, the wire wheel 15 stops rotating; Then the crane puts down the container, and the vertical positioning roller Ⅰ18 contacts the container placed below for vertical alignment, and the horizontal positioning roller 20 and the slide bar Ⅱ19 are aligned horizontally, so that the positions of the two containers are aligned, which is convenient for stacking the containers; then the hydraulic cylinder Ⅰ11 drives the positioning clamping rod 14 to flip, thereby driving the positioning slide bar Ⅰ16, and then driving the flip frame Ⅰ17 to be taken out from the gap between the two containers, and then the two containers are stacked together, not only in position, but also more tightly stacked; Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
