Description

Technical Field

[0001] This application relates to the field of engineering machinery technology, specifically to a safety hook drive device, a safety hook assembly, and a quay container crane. Background Technology

[0002] Quay cranes, also known as quay cranes, need to tilt and raise the front beam to approximately 80° when not in operation to protect the front beam structure. Current technologies mostly use electric mechanisms such as hydraulic electric actuators, electric support rods, or jacks to lift the safety hook and detach it from the front beam. Ensuring the lifting function of the electric mechanism requires calculation and design to install it in a specific position. Errors in welding and manufacturing can easily cause deviations between the electric mechanism's base dimensions and the theoretical dimensions. Furthermore, the force and stroke of the electric mechanism are limited, and improper counterweighting of the safety hook often results in slow lifting and lowering speeds. Poor coordination of related structures during the hooking and unhooking process makes it difficult to meet operational requirements. On the other hand, electric mechanisms are susceptible to various unpredictable malfunctions. Summary of the Invention

[0003] In view of this, this application provides a safety hook drive device, a safety hook assembly, and a quay container crane to solve the problems of poor structural fit and difficulty in meeting operational requirements, as well as potential failure risks of the electric mechanism in the prior art.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A safety hook drive device is disposed between a safety hook and a front beam, including a linkage assembly having an active end that is detachably connected to the front beam and a driven end that is detachably supported below the safety hook.

[0006] In the first pitching phase, the front beam can push the safety hook to lift and slide into the safety hook to hook; in the second pitching phase, the front beam can drive the linkage component through the active end, and cause the driven end to support the safety hook to lift and disengage from the front beam.

[0007] Optionally, it also includes a connecting hook disposed on the front beam, wherein the active end can be detachably hooked to the connecting hook; wherein,

[0008] During the first pitching phase, when the front beam pitches up, it causes the connecting hook to move closer to the active end and hook into the active end.

[0009] During the second pitching phase, when the front beam pitches, the active end is pushed to drive the linkage assembly, so that the driven end supports the safety hook upward until the hook is lifted and disengaged from the front beam.

[0010] During the second pitching phase, when the front beam pitches, the connecting hook pulls the active end to drive the linkage assembly, so that the driven end releases its support from the safety hook, and after the linkage assembly resets, the connecting hook separates from the active end.

[0011] Optionally, the linkage component includes:

[0012] The active component has a translational degree of freedom in the first linear direction, and the end opposite to the front beam is the active end;

[0013] The driven member has rotational freedom about a first rotation axis, and the end away from the first rotation axis is the driven end;

[0014] The transmission component is rotatably connected to both the driving component and the driven component;

[0015] During the second pitching phase, when the front beam pitches up, the driving member is pushed by the front beam and translates, causing the transmission member to drive the driven member to rotate until the safety hook is supported upwards and disengaged from the front beam. During the second pitching phase, when the front beam pitches down, the driving member is pulled by the connecting hook and translates in the opposite direction, causing the transmission member to drive the driven member to rotate in the opposite direction until the support for the safety hook is released. After the driving member translates in the opposite direction to the reset position, the connecting hook separates from the driving end.

[0016] Optionally, the connection between the driving member or the driven member and the transmission member has a sliding range. When the front beam moves during the second pitching phase, the transmission member first slides in the sliding range and then drives the driven member to rotate in the opposite direction, so that the movement of the front beam away from the safety hook occurs before the driven member releases the support of the safety hook.

[0017] Optionally, the active component is provided with the sliding section, which is a groove extending along the first straight line direction, and the transmission component is provided with a sliding body that is slidably connected to the groove.

[0018] Optionally, the trapezoidal frame is provided with a guide structure, the active member is slidably connected to the guide structure and can only reciprocate along the first straight line direction, and the active member is provided with a limiting structure to prevent the active member from slipping off the guide structure.

[0019] Optionally, the active component is rod-shaped, and the guide structure includes multiple fixed blocks fixedly mounted on the trapezoidal frame. The active component passes through all the fixed blocks and is slidably engaged with each of the fixed blocks. The limiting structure includes a stop block fixed to the active component. The stop block always blocks the outside of the fixed block as the active component reciprocates and translates. When the stop block located on the side away from the front beam contacts the fixed block, the active component is in the reset position.

[0020] Optionally, the trapezoidal frame is provided with a fixed seat, and the driven member is rotatably connected to the fixed seat.

[0021] Optionally, the fixed base is provided with a limiting block, which can prevent the driven member from continuing to rotate after the support for the safety hook is released.

[0022] Optionally, the driven member is rod-shaped and can rotate to vertically support the safety hook, with the driven end contacting the safety hook surface.

[0023] Optionally, the active end has a first guide slope, a second guide slope, and a hook position distributed in sequence. The connection between the first guide slope and the second guide slope protrudes outwards. The connecting hook can elastically deform and slide along the first guide slope and the second guide slope, and hooks with the active end at the hook position.

[0024] Optionally, the connecting hook includes:

[0025] The first component is fixedly connected to the front beam;

[0026] The second component is rotatably connected to the first component;

[0027] A tension spring is connected between the first part and the second part.

[0028] A safety hook assembly includes a safety hook, a limiting balance component, and a safety hook drive device as described above. The safety hook is rotatably connected to a support of a trapezoidal frame, and the limiting balance component is fixed to the trapezoidal frame. The safety hook drive device and the limiting balance component are located on opposite sides of the support. The safety hook is provided with a limiting groove into which the limiting balance component extends. When the safety hook rotates, it moves relative to the limiting balance component.

[0029] A quay container crane, comprising the safety hook assembly as described in any of the preceding claims.

[0030] The safety hook drive device provided in this application is disposed between the safety hook and the front beam, including a linkage assembly. The linkage assembly has an active end that is detachably connected to the front beam, and a driven end that is detachably supported below the safety hook. During the first tilting phase, the front beam can push the safety hook to lift and slide into the safety hook for hooking. During the second tilting phase, the front beam can drive the linkage assembly through the active end, causing the driven end to support the safety hook until it is lifted and disengaged from the front beam. With this configuration, in actual operation, whether hooking or disengaging from the safety hook, the front beam needs to tilt and slide. The linkage assembly itself is not electrically driven; it utilizes the movement of the front beam to provide power to the linkage assembly. The active end receives force, and the driven end makes a corresponding positional change. Through simple structural transmission, the lifting and lowering speed of the safety hook is synchronized with the tilting and sliding movement of the front beam. This results in strong linkage and high coordination, solving the problems of poor structural coordination and difficulty in meeting operational requirements, as well as potential failure risks of electric mechanisms in existing technologies that drive safety hooks.

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] Generally, the safety hook 01 is installed on the trapezoidal frame. The front beam 02 is pulled up and down by the rope. During the up and down movement, the front beam 02 moves closer to and away from the safety hook 01. The opening of the hook groove of the safety hook 01 for hooking with the front beam 02 faces downward, and the front end of the safety hook 01 near the front beam 02 has a hook bevel. The part of the front beam 02 that hooks with the safety hook 01 is a columnar impact bar.

[0050] This application provides a safety hook driving device, which is disposed between the safety hook 01 and the front beam 02 and located on a trapezoidal frame. It includes a linkage assembly, which has an active end 11 that is detachably connected to the front beam 02, and a driven end 12 that is detachably supported below the safety hook 01. In the first pitching phase, the front beam 02 can push the safety hook 01 to lift the hook and slide into the safety hook 01 to hook the hook. In the second pitching phase, the front beam 02 can drive the linkage assembly through the active end 11, and cause the driven end 12 to support the safety hook 01 to lift the hook and disengage it from the front beam 02.

[0051] It should be noted that in the first pitching phase, the front beam 02 first pitches towards the safety hook 01 and then pitches away from the safety hook 01. In this way, relying on the inherent structure of the front beam 02 and the safety hook 01, when the front beam 02 pitches, the impact rod and the hook ramp slide together, pushing the safety hook 01 upward to lift the hook until the impact rod slides into the hook groove. When the front beam 02 pitches, the impact rod pulls forward in the hook groove to complete the reliable hooking. In the second pitching phase, the front beam 02 also first pitches towards the safety hook 01 and then pitches away from the safety hook 01.

[0052] With this setup, during actual operation, whether hooking or unhooking with the safety hook 01, the front beam 02 needs to perform tilting and lowering movements. The linkage component itself is not electrically driven; the movement of the front beam 02 provides power to the linkage component. The driving end 11 is subjected to force, and the driven end 12 makes a corresponding positional change. Through simple structural transmission, the speed of lifting and lowering the safety hook 01 is synchronized with the tilting and lowering movements of the front beam 02. This setup has strong linkage and high coordination, solving the problems of poor structural coordination and difficulty in meeting operational requirements, as well as potential failure risks of the electric mechanism in the existing technology that drives the safety hook 01.

[0053] In one specific embodiment, the safety hook drive device further includes a connecting hook 13 disposed on the front beam 02, the connecting hook 13 being disposed opposite to the driving end 11, and the driving end 11 being detachably hooked to the connecting hook 13; wherein,

[0054] like Figures 1-3 As shown, when the front beam 02 tilts during the first pitching phase, in addition to sliding into the safety hook 01, it also drives the connecting hook 13 to approach the active end 11 and hook into the active end 11, without having a transmission effect on the driven end 12.

[0055] like Figure 4 As shown, during the first pitching phase, when the front beam 02 pitches down, it completes the action of hooking with the safety hook 01, but does not have a transmission effect on the driven end 12.

[0056] like Figures 5-6As shown, during the second pitching phase, when the front beam 02 pitches, the active end 11 is pushed to drive the linkage component, which deforms so that the driven end 12 supports the safety hook 01 upwards away from the front beam 02 to complete the hook lifting and disengage from the front beam 02.

[0057] like Figures 7-9 As shown, during the second pitching phase, when the front beam 02 pitches, the connecting hook 13 pulls the active end 11 to drive the linkage assembly. The linkage assembly deforms, causing the driven end 12 to release its support for the safety hook 01. After the linkage assembly resets, the connecting hook 13 separates from the active end 11, that is, the connecting hook 13 pulls away the support of the driven end 12 for the safety hook 01, and at the same time drives the entire linkage assembly to reset.

[0058] With this configuration, the front beam 02 approaches and contacts the active end 11 during the first pitching phase, and hooks it while pushing the active end 11. During the second pitching phase, the front beam 02 pushes and then pulls the linkage component to ensure that the linkage component can be reset after the hooking is completed, so that the next hooking and unhooking action can be carried out smoothly.

[0059] In one specific embodiment, the linkage component includes a driving member 101, a driven member 102, and a transmission member 103, all of which can be configured as rods; wherein,

[0060] The active component 101 has translational freedom in the first straight direction, and the end opposite to the front beam 02 is the active end 11;

[0061] The driven member 102 has rotational freedom about the first rotation axis, and the end away from the first rotation axis is the driven end 12;

[0062] The transmission component 103 is rotatably connected to the driving component 101 and the driven component 102, and can be hinged through a shaft. The position where the driving component 101 is connected to the transmission component 103 is located on the side away from the front beam 02, and the position where the driven component 102 is connected to the transmission component 103 is located between the two ends of the driven component 102.

[0063] The transmission member 103 and the driven member 102 are located diagonally above the driving member 101;

[0064] During the second pitching phase, when the front beam 02 pitches up, the driving member 101 is pushed by the front beam 02 and moves in a horizontal direction, so that the transmission member 103 pushes the driven member 102 to rotate until the safety hook 01 is supported upwards and disengaged from the front beam 02. During the second pitching phase, when the front beam 02 pitches down, the driving member 101 is pulled by the connecting hook 13 and moves in the opposite direction, so that the transmission member 103 pulls the driven member 102 to rotate in the opposite direction until the support for the safety hook 01 is released. Moreover, after the driving member 101 moves in the opposite direction to the reset position, it can no longer move in a horizontal direction, and the connecting hook 13 is pulled by the front beam 02 and separates from the driving end 11.

[0065] In a preferred embodiment, the connection between the driving member 101 or the driven member 102 and the transmission member 103 has a sliding range. When the front beam 02 moves in the second pitching phase, the transmission member 103 first slides in the sliding range and then drives the driven member 102 to rotate in the opposite direction, so that the movement of the front beam 02 away from the safety hook 01 is before the driven member 102 releases the support of the safety hook 01.

[0066] With this configuration, due to the existence of the sliding range, when the front beam 02 tilts upwards in the second pitching phase, the driving member 101 moves a certain distance before the driven member 102 can be pushed. Similarly, when the front beam 02 tilts downwards in the second pitching phase, the driving member 101 moves a certain distance in the opposite direction before the driven member 102 can be pulled. At this time, the front beam 02 has moved a certain distance away from the safety hook 01, ensuring that after the support of the driven member 102 is removed, the safety hook 01 will not hook onto the front beam 02 again.

[0067] Furthermore, the drive member 101 can be optionally configured to have a sliding section, which is a groove 104 extending along a first straight line. The transmission member 103 is provided with a sliding body slidably connected to the groove 104. When the drive member 101 translates, the groove 104 and the sliding body move relative to each other. That is, the transmission member 103 can only be pushed or pulled by the drive member 101 when the drive member 101 translates to the point where the sliding body is located at both ends of the groove 104. The sliding body can be a hinge pin on the transmission member 103 connected to the drive member 101, or it can be a rolling wheel.

[0068] In a more specific embodiment, the trapezoidal frame is provided with a guide structure, the active member 101 is slidably connected to the guide structure and can only reciprocate along a first linear direction, and the active member 101 is provided with a limiting structure to prevent the active member 101 from slipping off the guide structure. In this way, it is ensured that the active member 101 can only translate within a fixed direction and a fixed range when subjected to force.

[0069] Furthermore, the active component 101 is rod-shaped, and the guide structure includes multiple fixed blocks 105 fixedly mounted on the trapezoidal frame. The active component 101 passes through all the fixed blocks 105 and is slidably engaged with each fixed block 105. The limiting structure includes a stop block 106 fixedly attached to the active component 101. The stop block 106 always blocks the outside of the fixed blocks 105 as the active component 101 reciprocates, enabling the active component 101 to translate within a fixed range. When the stop block 106 located on the side away from the front beam 02 contacts the fixed block 105, the active component 101 is in the reset position. The guide structure can also be a groove structure mounted on the trapezoidal frame.

[0070] With this configuration, after the active component 101 moves in the opposite direction to a fixed position, it will not move again even if it is pulled. At this time, the connecting hook 13 still has the ability to move away from the active end 11, and finally separates from the active end 11 under the drive of the front beam 02.

[0071] In addition, a fixed seat 107 is provided on the trapezoidal frame, and the driven member 102 is rotatably connected to the fixed seat 107, specifically by hinge through the first rotating shaft.

[0072] Furthermore, the fixed base 107 is provided with a limiting block 108, which can prevent the driven member 102 from continuing to rotate after releasing its support from the safety hook 01. Specifically, the end of the driven member 102 is flat, and after it rotates to a certain position, the limiting block 108 can stop it at its end, thereby preventing it from continuing to rotate. In this way, the limiting block 108 restricts the driven member 102 to rotate within a fixed rotation range, preventing the situation where the rotation position is uncontrollable and the next action cannot be controlled.

[0073] In another preferred embodiment, the driven member 102 is rod-shaped and can rotate to vertically support the safety hook 01, with the driven end 12 contacting the surface of the safety hook 01. This ensures reliable and stable support of the safety hook 01 by the driven member 102.

[0074] In another specific embodiment, such as Figure 10 As shown, the active end 11 has a first guide slope 111, a second guide slope 112 and a hook position 113 arranged in sequence. The connection between the first guide slope 111 and the second guide slope 112 protrudes outwards. The connecting hook 13 can elastically deform and slide along the first guide slope 111 and the second guide slope 112, and hooks with the active end 11 at the hook position 113.

[0075] With this configuration, when the front beam 02 tilts during the first pitching phase, the connecting hook 13 contacts the active end 11. Under the action of the first guide slope 111, it slides along the first guide slope 111 while generating elastic deformation. It then passes through the second guide slope 112 and reaches the hook position 113, completing the hooking. When the front beam 02 tilts during the second pitching phase, the connecting hook 13 will not separate under the condition that the reverse translational resistance of the active member 101 is small. It can generate a pulling effect on the active member 101. When the driven member 102 reaches the reset position, the stop block 106 prevents it from continuing to move. The resistance is extremely large. At this time, the connecting hook 13 elastically deforms again and slides out along the second guide slope 112 and separates.

[0076] like Figure 10 As shown, more specifically, the connecting hook 13 includes a first part 131 fixedly connected to the front beam 02, a second part 132 rotatably connected to the first part 131, and a tension spring 133 connected between the first part 131 and the second part 132. The first part 131 and the second part 132 are in an obtuse angle relationship in their natural state, and the tension spring 133 applies a force to prevent the included angle from increasing.

[0077] With this configuration, when the second part 132 slides along the first guide slope 111, since the tension spring 133 itself does not hinder the angle between the first part 131 and the second part 132 from becoming smaller, the second part 132 can easily rotate and slide along the first guide slope 111 until it slides to the hook position 113. Due to the tension of the tension spring 133, under the condition that the reverse translation resistance of the active member 101 is small, the connecting hook 13 can keep the hook connected to the active end 11 without separation. Furthermore, due to the guiding effect of the second guide slope 112, it is also possible for the second part 132 to leave the active end 11.

[0078] Based on the aforementioned safety hook drive device, this application embodiment also provides a safety hook assembly, which includes a safety hook 01, a limiting balance component 04, and the aforementioned safety hook drive device. The safety hook 01 is rotatably connected to a support 03 of a trapezoidal frame, and the limiting balance component 04 is fixed to the trapezoidal frame. The safety hook drive device and the limiting balance component 04 are located on opposite sides of the support 03. The safety hook 01 has a limiting groove into which the limiting balance component 04 extends. When the safety hook 01 rotates, it moves relative to the limiting balance component 04, meaning the limiting balance component 04 and the limiting groove are always slidably connected. Taking the hinge point of the support 03 as the boundary, the length of the safety hook 01 on the side where the linkage component is located is greater than the length of the safety hook 01 on the side where the limiting balance component 04 is located.

[0079] With this configuration, thanks to the assistance of the limiting and balancing component 04, the safety hook 01 will not experience swaying or shaking due to unilateral force or imbalance at both ends, thus preventing problems that could affect its service life. This allows the safety hook 01 to rotate in a more stable state. Unlike existing technologies that use an electric mechanism to lift the safety hook 01 in conjunction with a counterweight to stabilize its rotation, the method provided in this application eliminates the need for a counterweight, avoiding the cumbersome problem of adjusting the overall counterweight balance of the safety hook 01.

[0080] Furthermore, since the safety hook assembly has the aforementioned safety hook drive device, the beneficial effects of the safety hook assembly brought about by the safety hook drive device can be found in the above content, and will not be repeated here.

[0081] Based on the aforementioned safety hook assembly, this application also provides a quay container crane that includes the aforementioned safety hook assembly. Since this quay container crane has the aforementioned safety hook assembly, the beneficial effects brought by the safety hook assembly to the quay container crane are described above and will not be repeated here.
