For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0026] The same or similar numbers in the drawings of the embodiments of the present invention correspond to the same or similar parts; in the description of the present invention, it should be understood that if the terms "upper", "lower", "left", "right", "long", "short" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, they are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0027] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0028] Example 1

[0029] like Figures 1 to 4As shown, a hook mechanism comprises a mounting seat 1, a hook assembly 2, a connecting rod assembly 3 and an elastic assembly 4; the hook assembly 2 comprises a first pin shaft 21, a first sleeve 22 and a hook 23, the first pin shaft 21 is mounted on the mounting seat 1, the first sleeve 22 is sleeved on the first pin shaft 21, and the hook 23 is sleeved on the first sleeve 22; an oil passage 24 is arranged in the first pin shaft 21, the oil passage 24 has an oil filling port 241 and an oil outlet port 242, the oil outlet port 242 is arranged on the circumference of the first pin shaft 21 and faces the inner circumference of the first sleeve 22; one end of the connecting rod assembly 3 is rotatably connected to the hook 23, and the other end thereof is rotatably connected to the mounting seat 1; one end of the elastic assembly 4 is rotatably connected to the hook 23, and the other end thereof is movably connected to the mounting seat 1; when the connecting rod assembly 3 is forced to move upward, the connecting rod assembly 3 drives the hook 23 to rotate to unhook and compress the elastic assembly 4.

[0030] In this embodiment, when in use, the mounting base 1 is installed on the column 101 of the super-elevated frame. Since an oil passage 24 is provided in the first pin shaft 21, the oil passage 24 has an oil filling port 241 and an oil outlet port 242. The oil outlet port 242 is opened on the circumferential surface of the first pin shaft 21 and faces the inner circumferential surface of the first sleeve 22. Lubricating oil can be injected into the oil passage 24 through the oil filling port 241. The lubricating oil flows out from the oil outlet port 242 and can lubricate the contact surface between the first pin shaft 21 and the first sleeve 22, thereby reducing the friction between the first pin shaft 21 and the first sleeve 22, thereby reducing the friction of the hook 23 during the opening and closing process, and avoiding the problems of jamming and poor movement of the hook 23 during the opening and closing process.

[0031] It should be noted that, since one end of the elastic component 4 is rotatably connected to the hook 23 and the other end thereof is movably connected to the mounting seat 1, the hook 23 can push the elastic component 4 to move relative to the mounting seat 1 during the unlocking and rotating process, thereby compressing the elastic component 4. More specifically, when in use, the hook mechanism is fixedly mounted on the column 101 of the super-elevated frame through the mounting seat 1, so that it is connected to the super-elevated frame. When the super-elevated frame is stored in the trailer 13, the top pin 131 on the trailer 13 pushes the connecting rod component 3 from bottom to top, and the elastic component 4 is in a compressed state. At this time, the hook 23 is in an open state, and the hook 23 cannot rotate in the direction of closing the hanging ear 12. When the super-elevated frame needs to be taken, after the sling is connected to the super-elevated frame, when the sling lifts the super-elevated frame away from the trailer 13, since the top pin 131 on the trailer 13 no longer generates a thrust force on the connecting rod component 3, the elastic component 4 drives the hook 23 to move in the closing direction to restore the deformation, thereby realizing the locking between the hook 23 and the hanging ear 12 of the sling. The sling can be used together with the super-high frame to complete the container lifting operation. It should also be pointed out that the first pin 21 and the mounting seat 1 can be fixedly connected or rotatably connected, but the hook 23 sleeved on the first shaft sleeve 22 can rotate relative to the mounting seat 1.

[0032] like Figure 4 As shown, the oil filling port 241 is formed on the end face of the first pin shaft 21, the oil passage 24 includes a first flow passage 243 and a second flow passage 244 which are interconnected, the oil filling port 241 is located at the head end of the first flow passage 243 along the flow direction of the lubricating oil, and the oil outlet 242 is located at the tail end of the second flow passage 244 along the flow direction of the lubricating oil. In this embodiment, since the oil filling port 241 is located on the end face of the first pin shaft 21, it is convenient to fill the oil passage 24 with lubricating oil through the oil filling port 241 on the end face of the first pin shaft 21, and the lubricating oil flows into the second flow passage 244 along the first flow passage 243, and then flows out from the oil outlet 232.

[0033] like Figure 4 As shown, the first flow channel 243 extends along the end surface of the first pin shaft 21 where the oil filling port 241 is located toward the other end surface of the first pin shaft 21 , and the second flow channel 244 extends from the oil outlet 242 toward the first flow channel 243 and communicates with the first flow channel 243 .

[0034] like Figure 4 As shown, an oil nozzle 245 is installed in the oil filling port 241. In this embodiment, since the oil nozzle 245 is installed in the oil filling port 241, the lubricating oil can be easily and quickly injected into the oil passage 24, and the lubricating oil can also be prevented from leaking from the oil filling port 241. It should be noted that the oil nozzle 245 can be detachably connected to the oil filling port 241, so that the oil nozzle 245 is easy to clean.

[0035] like Figures 1 to 3 and Figure 7 As shown, the connecting rod assembly 3 includes a first connecting rod 31 and a second connecting rod 32, the first connecting rod 31 is located above the second connecting rod 32, one end of the first connecting rod 31 is rotatably connected to the hook 23, the other end of the first connecting rod 31 is rotatably connected to one end of the second connecting rod 32, the other end of the second connecting rod 32 is rotatably connected to the mounting base 1, and a first connection position where the first connecting rod 31 and the second connecting rod 32 are connected is located on a side away from the elastic component 4 at a second connection position where the second connecting rod 32 and the mounting base 1 are connected; the connecting rod assembly 3 has a stop block 33, which is formed at one end of the second connecting rod 32 connected to the first connecting rod 31.

[0036] In this embodiment, when the super-high frame is stored in the position of the trailer 13, the top pin 131 on the trailer 13 presses against the bottom of the second connecting rod 32, the elastic component 4 is in a compressed state, and the stopper 33 on the second connecting rod 32 is located above the turntable 108. The turntable 108 limits the movement of the stopper 33. At this time, the hook 23 is in an open state and the hook 23 cannot rotate in the closing direction. When it is necessary to take the super-high frame, the rotary lock of the lifting device is inserted into the driving member 107 and rotated, so that the rotary lock is connected to the column 101. When the rotary lock rotates, it drives the driving member 107 to drive the turntable 108 to rotate, so that the notch 109 after the turntable 108 rotates can be directly opposite to the position of the stop block 33, and the turntable 108 will not hinder the rotation movement of the stop block 33; when the lifting device lifts the super-high frame from the position 13, the top pin 131 on the trailer 13 no longer generates a thrust force on the second connecting rod 32, and the stop block 33 can rotate through the notch 109, the elastic component 4 drives the hook 23 to move in the closing direction to restore the deformation, thereby realizing the locking between the hook 23 and the hook ear 12 of the lifting device.

[0037] like Figures 1 to 4 As shown, the elastic component 4 includes a pull rod 41 and a spring 42, and the spring 42 is sleeved on the pull rod 41; a second pin shaft 5 is rotatably mounted on the mounting seat 1, and a through hole 51 is opened on the circumferential surface of the second pin shaft 5, and one end of the pull rod 41 passes through the through hole 51; one end of the spring 42 is connected to the end of the pull rod 41 away from the hook 23, and the other end of the spring 42 abuts against the outer circumferential surface of the second pin shaft 5, specifically, the other end of the spring 42 abuts against the outer circumferential surface of the second pin shaft 5 at the end of the through hole 51 away from the hook 23. In this embodiment, after the spreader and the super-high frame complete the lifting operation of the container, when the super-high frame needs to be placed back on the trailer 13, the spreader places the super-high frame on the trailer 13, and the top pin 131 on the trailer 13 presses the connecting rod assembly 3, the rotary lock rotates so that the notch 109 on the turntable 108 faces the block 33, and the connecting rod assembly 3 can rotate through the notch 109 under the pushing action of the top pin 131, and then the connecting rod assembly 3 pushes the hook 23 away from the spreader, so that the hook 23 is unlocked. In the process of unlocking the hook 23, the hook 23 pushes the pull rod 41 to move and compresses the spring 42 sleeved on the pull rod 41.

[0038] like Figures 1 to 4As shown, one end of the first connecting rod 31 and the hook 23, the other end of the first connecting rod 31 and one end of the second connecting rod 32, and the pull rod 41 and the hook 23 are rotationally connected respectively through the third pin shaft 6, the fifth pin shaft 7 and the sixth pin shaft 8; the third pin shaft 6, the fifth pin shaft 7 and the sixth pin shaft 8 are respectively sleeved with a third shaft sleeve; the second pin shaft 5 is sleeved with a second shaft sleeve 52 installed on the mounting seat 1; the end of the second connecting rod 32 rotationally connected to the mounting seat 1 is rotationally connected through the fourth pin shaft 9, the fourth pin shaft 9 can be fixedly connected to the mounting seat 1 or rotationally connected, the fourth pin shaft 9 is sleeved with a fourth shaft sleeve 91, but the second connecting rod 32 sleeved on the fourth shaft sleeve 91 needs to be rotationally connected relative to the mounting seat 1; the fourth pin shaft 9 is provided with an oil channel 24, and the oil outlet 242 of the oil channel 24 faces the inner circumferential surface of the fourth shaft sleeve 91. In this embodiment, since the third pin shaft 6, the fifth pin shaft 7 and the sixth pin shaft 8 are respectively sleeved with the third sleeve, the friction between the first connecting rod 31 and the hook 23 during rotation can be reduced by the provision of the third sleeve, and the friction between the first connecting rod 31 and the second connecting rod 32 during rotation can be reduced, and the friction between the pull rod 41 and the hook 23 during rotation can be reduced. In addition, since the fourth pin shaft 9 on the second connecting rod 32 is also provided with an oil passage 24, lubricating oil can be transported between the fourth pin shaft 9 of the second connecting rod 32 and the fourth sleeve 91 through the oil passage 24, thereby reducing the friction between the fourth pin shaft 9 and the fourth sleeve 91. Since the second pin shaft 5 is sleeved with the second sleeve 52 installed on the mounting seat 1, the second pin shaft 5 can rotate relative to the mounting seat 1 more smoothly.

[0039] Example 2

[0040] like Figure 2 , Figure 5 , Figure 6 As shown, a super-high frame includes a main body 10 and a hook mechanism as described above, the main body 10 has a column 101, and a mounting seat 1 is fixedly or height-adjustably connected to the column 101. In this embodiment, the mounting seat 1 and the column 101 can be fixedly connected by welding, or by other connection methods. When the mounting seat 1 is height-adjustably connected to the column 101, the height of the hook mechanism in the vertical direction on the column 101 can be adjusted by adjusting the height of the mounting seat 1 on the column 101, and then the vertical distance between the hook 23 and the hanging ear 12 of the sling can be adjusted, so as to achieve high-precision installation of the hook mechanism and prevent jamming caused by manufacturing errors. It should be noted that the column 101 can be provided with 4, and the two side columns 101 on the same side are connected by a crossbeam 110, and the two crossbeams 110 on the opposite side are connected by a main beam 111, and the main beam 111 and the crossbeam 110 can be connected by a telescopic connection.

[0041] like Figure 6As shown, a first connecting hole is provided on the column 101, and the first connecting hole is a waist hole along the vertical direction in the length direction. A second connecting hole is provided on the mounting seat 1 at a position corresponding to the first connecting hole, and a fastener 102 is connected between the first connecting hole and the second connecting hole; a first limit block 103 and a second limit block 104 are respectively provided on the column 101 and located on the top side and the bottom side of the mounting seat 1; a first gap 105 is provided between the first limit block 103 and the upper surface of the mounting seat 1 in the vertical direction, and a first adjusting gasket is installed in the first gap 105; a second gap 106 is provided between the second limit block 104 and the lower surface of the mounting seat 1 in the vertical direction, and a second adjusting gasket is installed in the second gap 106. In this embodiment, as required, a first gasket is installed in the first gap 105 so that the two sides of the first gasket are in contact with the upper surface of the mounting seat 1 and the lower surface of the first stopper 103 respectively. The first gasket can be multiple pieces, but it is necessary to ensure that the total thickness of the first gasket installed in the first gap 105 is equal to the height of the first gap 105 in the vertical direction. A second gasket is installed in the second gap 106 so that the two sides of the second gasket are in contact with the lower surface of the mounting seat 1 and the upper surface of the second stopper 104 respectively. The second gasket can be multiple pieces, but it is necessary to ensure that the total thickness of the second gasket installed in the second gap 106 is equal to the height of the second gap 106 in the vertical direction. In this way, on the one hand, the accuracy of the hook mechanism installed on the column 101 through the mounting seat 1 can be ensured to prevent jamming caused by manufacturing errors. On the other hand, during the operation of the super-high frame, the first gasket, the first stopper 103, the second gasket and the second stopper 104 can withstand more force to avoid the problem of connection failure caused by excessive shear force on the fastener 102 connected in the first connection hole and the second connection hole. It should be noted that, according to assembly requirements, when the fastener 102 is installed in the waist hole, it can be adjusted in the length direction of the waist hole; the size of the second connection hole is adapted to the fastener 102, the second connection hole can be a round hole, and the vertical position of the fastener 102 in the second connection hole is difficult to adjust; the fastener 102 can be set as a bolt, or a screw, or other structures that can be connected to the first connection hole and the second connection hole to achieve fastening between the mounting base 1 and the column 101. The number of first connection holes and the corresponding number of second connection holes can be set as required.

[0042] Example 3

[0043] like Figure 2 , Figure 7 As shown, the difference from Example 2 is that a driving member 107 is provided in the column 101, and the driving member 107 is connected to a turntable 108. The turntable 108 has a notch 109 for a stopper 33 provided on the connecting rod assembly 3 to pass through. The stopper 33 causes the connecting rod assembly 3 to rotate through the notch 109 to drive the hook 23 to unhook.

[0044] In this embodiment, when the super-high frame is stored in the position of the trailer 13, the top pin 131 on the trailer 13 presses against the bottom of the connecting rod assembly 3, the elastic assembly 4 is in a compressed state, and the block 33 on the connecting rod assembly 3 is located on the turntable 108. The turntable 108 limits the movement of the block 33. At this time, the hook 23 is in an open state and the hook 23 cannot rotate in the closing direction. When it is necessary to take the super-high frame, the rotary lock of the spreader is inserted into the driving member 107 and rotated, so that the rotary lock is connected to the column 101. When the rotary lock rotates, it drives the driving member 107 to drive the turntable 108 to rotate, so that the notch 109 of the turntable 108 after rotation can face the position of the block 33, and the turntable 108 will not hinder the rotation of the block 33; when the spreader lifts the super-high frame away from the trailer 13, since the top pin 131 on the trailer 13 no longer generates a thrust force on the connecting rod assembly 3, and the block 33 can rotate through the notch 109, the elastic component 4 drives the hook 23 to move in the closing direction to restore the deformation, and the hook 23 is locked with the hook ear 12 of the spreader. In the locked state, the rotary lock is rotated so that the turntable 108 blocks the block 33 from moving upward and the block 33 is located below the turntable 108. The spreader can complete the lifting operation of the container together with the super-high frame. After the spreader and the super-high frame complete the lifting operation of the container, when the super-high frame needs to be placed back on the trailer 13, the spreader places the super-high frame on the trailer 13, and the top pin 131 on the trailer 13 presses against the connecting rod assembly 3, the rotary lock rotates so that the notch 109 on the turntable 108 faces the block 33, and the connecting rod assembly 3 can rotate through the notch 109 under the push of the top pin 131, and then the connecting rod assembly 3 pushes the hook 23 to separate from the hook ear 12 of the spreader, so that the hook 23 is unlocked. In the process of unlocking the hook 23, the hook 23 pushes the pull rod 41 to move and compresses the spring 42 sleeved on the pull rod 41.

[0045] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
