Description

Technical Field

[0001] The present application relates to quay crane equipment technology, and in particular to an anchoring device for fixing a pitching mechanism of a quay crane and a quay crane. Background Art

[0002] A shore-to-shore container crane, also known as a quay crane or bridge crane, consists of three major systems: a hoisting mechanism, a luffing mechanism, and a trolley. The luffing mechanism includes a front beam and a ladder frame that is anchored to a locking head on the front beam. When not in operation, to ensure the safety of the waterway and the vessel, the luffing mechanism raises the front beam and secures it with a locking member on the ladder frame that hooks to the locking head on the front beam.

[0003] Currently, methods for securing the front beam include manual latch anchoring and locking, and automatic anchoring with a lifting hook. The manual latch anchoring method requires the operator to climb onto the ladder frame to manually operate, which is time-consuming and labor-intensive. The automatic anchoring method uses a motor or hydraulic push rod to drive the locking member and the locking head to lock and unlock. This is complex and has high maintenance costs. Therefore, all of these front beam securing methods have certain limitations. Summary of the Invention

[0010] In some possible embodiments, the slide has an opening for the lock head assembly to enter, and the first trigger member and the second trigger member are arranged in sequence in a direction away from the opening, so that the lock head assembly entering the slide pushes the first trigger member and the second trigger member in sequence.

[0018] The second push rod is configured to drive the second transmission shaft to rotate under the pushing force of the lock assembly in the first direction.

[0019] In some possible implementations, a support platform is provided at one end of the mounting bracket close to the opening of the slideway, and the support platform is used to support the locking member so that the locking member remains in an unlocked state.

[0020] In some possible implementations, the support platform is provided with a first detection member for detecting whether the locking member is in an unlocked state;

[0045] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0046] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to a fixed connection, an indirect connection via an intermediate medium, internal communication between two components, or an interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0047] In the description of this application, it should be understood that the terms "up", "down", "front", "back", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on this application.

[0048] The terms "first," "second," "third," "fourth," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the application described herein can, for example, be implemented in an order other than that illustrated or described herein.

[0049] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0050] As mentioned in the background art, there are two types of front beam locking structures for fixing the pitch mechanism in the related art.

[0051] One type uses a purely mechanical mechanism. For example, when the front beam lock is inserted into the fixed structure, a handle is manually lifted. Leverage causes a pin linked to the handle to descend and insert into the lock on the front beam, securing the lock. To unlock, the handle is manually pressed down, causing the pin to extend from the lock, completing the unlocking process. This mechanism requires the operator to climb up the ladder frame for manual operation, which is time-consuming and labor-intensive, and also carries certain risks associated with working at height.

[0052] Another type of anchoring mechanism is an automatic anchoring mechanism. For example, after the front beam pitch mechanism lock head is raised to the corresponding position, an electric hydraulic push rod drives a locking member to hook the pitch mechanism beam lock head, completing the anchoring and unlocking. Automatic anchoring mechanisms rely on expensive hydraulic or electric push rods, which are expensive to maintain and use, making them unsuitable for long-term use in the open air environment of ports.

[0053] Based on this, an embodiment of the present application provides an anchoring device and a quay crane for fixing the pitching mechanism of the quay crane. In the anchoring device, the locking head assembly pushes the first trigger member when entering the slide to directly drive the locking member from the unlocked state to the locked state. When unlocking, the locking head assembly pushes the second trigger member to drive the locking member from the locked state to the unlocked state. No manual climbing or manual operation is required throughout the process, which reduces manpower and achieves the effect of automatically locking and unlocking the locking head assembly.

[0054] In addition, the state switching of the above-mentioned locking member is completed through the self-movement of the lock head assembly, without the use of motors or other active drive components such as hydraulics, which is conducive to simplifying the structure, reducing maintenance costs, and reducing the impact and interference of unexpected environmental factors such as power outages, salt spray corrosion, typhoons, etc., and is suitable for long-term use and operation in ports.

[0055] The following describes the solutions of the embodiments of the present application with reference to the accompanying drawings.

[0056] like Figure 1 As shown, an embodiment of the present application provides an anchoring device for fixing a pitching mechanism of a quay crane, the anchoring device including a mounting bracket 100 , a locking member 200 and a transmission assembly 300 .

[0057] The mounting bracket 100 is used to connect with the truss of the quay crane. The mounting bracket 100 is provided with a slideway 101, and the slideway 101 is used for the lock assembly 400 on the pitch mechanism of the quay crane to enter; the locking member 200 is rotatably provided on the mounting bracket 100, and the locking member 200 has a locking state of blocking the slideway 101 and an unlocking state of not blocking the slideway 101; the transmission assembly 300 is provided on the mounting bracket 100, and the transmission assembly 300 includes a first trigger member 301 extending into the slideway 101. and the second trigger member 302, the first trigger member 301 and the second trigger member 302 are both transmission connected to the locking member 200; wherein, the first trigger member 301 is configured to drive the locking member 200 to rotate under the pushing force of the lock head assembly 400, so that the locking member 200 is switched from the unlocked state to the locked state; the second trigger member 302 is configured to drive the locking member 200 to rotate under the pushing force of the lock head assembly 400, so that the locking member 200 is switched from the locked state to the unlocked state.

[0058] From the above description, it can be seen that the anchoring device for fixing the pitching mechanism of the quay crane provided in the embodiment of the present application, when the locking assembly 400 enters the slide 101 of the mounting bracket 100, contacts the first trigger member 301 and the second trigger member 302 of the transmission assembly 300, and the locking assembly 400 uses the pushing force of the first trigger member 301 and the second trigger member 302 to switch the unlocking state and the locking state of the locking member 200. The unlocking and locking actions of the locking member 200 are triggered by the transmission connection between the first trigger member 301 and the second trigger member 302. No manual climbing or manual operation is required throughout the process, which reduces manpower and achieves the effect of automatically locking and unlocking the locking assembly 400.

[0059] In addition, the state switching of the above-mentioned locking member is completed through the self-movement of the lock head assembly 400, without the use of motors or other active driving components such as hydraulics, which is conducive to simplifying the structure, reducing maintenance costs, and reducing the impact and interference of unexpected environmental factors such as power outages, salt spray corrosion, typhoons, etc., and is suitable for long-term use and operation in ports.

[0060] like Figure 2 As shown, in this embodiment of the present application, the mounting bracket 100 is used to connect to the truss of the quay crane. The truss of the quay crane refers to the basic structure of the quay crane, that is, the quay crane body. The quay crane body includes, among other things, a rear beam 600 rotatably connected to the front beam 500 and a ladder frame 700 mounted on the rear beam 600. The mounting bracket 100 can be secured to the ladder frame 700 by welding or bolting. For example, the lower end of the mounting bracket 100 is configured with a plurality of protruding connecting posts 107. The connecting posts 107 are connected to the ladder frame 700 by welding or by bolts running through both.

[0061] like Figure 2As shown, in general, the front beam 500 is connected to the ladder frame 700 on the rear beam 600 through two foldable pull rods 800. One end of the pull rod 800 is fixed to the ladder frame 700, and the other end is connected to the front beam 500. A lock assembly 400 is fixed on one of the pull rods 800 or the front beam 500. A wire rope 900 that can be controlled to reel in and out is provided on the pull rod 800. When the front beam 500 needs to be lifted, the reeling mechanism retracts the wire rope 900, so that the front beam 500 can be lifted along the Figure 2 , the front beam 500 is rotated counterclockwise as shown in the figure to lift it. The locking head assembly 400 on the front beam 500 enters the anchoring device, and the locking member 200 of the anchoring device hooks the locking head assembly 400, completing the fixation of the front beam 500 to the ladder frame 700. When the front beam 500 needs to be lowered, the locking head assembly 400 disengages the locking member 200, and the front beam 500 falls under the traction of the wire rope 900 until the pull rod 800 pulls the front beam 500 to make the front beam 500 and the rear beam 600 level.

[0062] like Figure 1 and Figure 3 As shown, in the anchoring device in the embodiment of the present application, the slide 101 has an opening 102 for the lock head assembly 400 to enter, and the first trigger member 301 and the second trigger member 302 are arranged in sequence along the direction away from the opening 102, so that the lock head assembly 400 entering the slide 101 pushes the first trigger member 301 and the second trigger member 302 in sequence.

[0063] The slideway 101 in the above embodiment is a slideway 101 with a one-way opening 102. The lock assembly 400 can only enter the slideway 101 through the opening 102. Figure 1 For example, when the front beam 500 is pulled upward by the wire rope 900, the lock assembly 400 enters the slideway 101 from the opening 102. When the front beam 500 is pulled downward by the wire rope 900, the lock assembly 400 is released from the opening 102 from the inside of the slideway 101. In the above arrangement, the slideway 101 is designed as a single-direction path. The travel path of the lock assembly 400 directly affects the triggering action of the first trigger member 301 and the second trigger member 302. Therefore, compared with other transmission structures, the lock assembly 400 that moves in and out directly is more likely to push the first trigger member 301 and the second trigger member 302, causing the first trigger member 301 and the second trigger member 302 to be triggered and respond.

[0064] like Figure 3As shown, further, the transmission assembly 300 in the embodiment of the present application also includes a transmission rod 303 slidably arranged on the mounting bracket 100, and the opposite sides of the transmission rod 303 are respectively provided with a first tooth portion 3031 and a second tooth portion 3032 extending along its own length direction; the first tooth portion 3031 is in transmission cooperation with the first trigger member 301, and the second tooth portion 3032 is in transmission cooperation with the second trigger member 302 and the locking member 200, and the transmission rod 303 is configured to drive the locking member 200 to rotate under the transmission force of the first trigger member 301 or the second trigger member 302.

[0065] The transmission rod 303 in the above embodiment is slidably connected to the mounting bracket 100, and the sliding path of the transmission rod 303 is parallel to the travel path of the lock head in the slide 101. For example, two annular clamps are provided on the side wall of the mounting bracket 100, and the transmission rod 303 is limited in the two clamps and can slide left and right relative to the clamps in the figure.

[0066] It should be noted that since the locking member 200 and the locking head assembly 400 of the anchoring device are generally used in typhoon weather or to avoid ships and waterways, the locking member 200 and the locking head assembly 400 are not used frequently, and the friction loss between the transmission rod 303 and the clamp is not large. In the embodiment of the present application, the transmission rod 303 is directly slid into the clamp. Of course, as an alternative embodiment, a separate slide rail can also be provided on the mounting bracket 100 to cooperate with the transmission rod 303, as long as it does not affect the transmission function of the first trigger member 301, the second trigger member 302 and the transmission rod 303.

[0067] by Figure 3 Taking the direction shown in the figure as an example, the lower end of the transmission rod 303 is provided with a first tooth portion 3031, and the upper end of the transmission rod 303 is provided with a second tooth portion 3032. The first tooth portion 3031 cooperates with the first trigger member 301 to achieve locking, and the second tooth portion 3032 links the second trigger member 302 and the locking member 200 to complete unlocking. As a result, the transmission rod 303 slides linearly relative to the mounting bracket 100, directly converting the pushing force exerted on the first trigger member 301 and the second trigger member 302 into a rotational torque of the locking member 200. This shortens the path, reduces energy loss, and makes the action response more rapid and reliable. In addition, the use of a single transmission rod 303 to achieve bidirectional action transmission also effectively avoids the redundancy of using multiple components in the transmission, thereby improving mechanical efficiency.

[0068] like Figure 4As shown, in some embodiments, the first trigger member 301 includes a first transmission shaft 3011 and a first push rod 3012 sleeved on the first transmission shaft 3011, and the first transmission shaft 3011 is connected to the first tooth portion 3031; the first push rod 3012 is configured to drive the first transmission shaft 3011 to rotate under the pushing force of the lock head assembly 400 in the first direction, and not to drive the first transmission shaft 3011 to rotate under the pushing force of the lock head assembly 400 in the second direction, and the first direction and the second direction are opposite.

[0069] The first trigger member 301 in the above embodiment hangs down under the action of gravity to block part of the path of the slide 101. After the lock head assembly 400 enters the slide 101, it first pushes the first trigger member 301 to rotate the first trigger member 301 in the first direction, thereby switching the locking member 200 from the unlocked state to the locked state. However, since the lock head assembly 400 is not directly engaged with the locking member 200, it needs to retreat along the original path to the opening 102 near the slide 101 to engage with the locking member 200. When the lock head assembly 400 retreats, it pushes the first trigger member 301 to rotate the first trigger member 301 in the second direction. At this time, the rotation in the second direction does not affect the locking of the locking member 200, thereby ensuring the stable locking state of the locking member 200.

[0070] Specifically, the first transmission shaft 3011 is provided with a gear 3013 for transmission cooperation with the first tooth portion 3031, the first transmission shaft 3011 is provided with a limit block 3014 protruding in the radial direction, and the first push rod 3012 is provided with a fixed block 3015; under the pushing force of the lock head assembly 400 in the first direction, the fixed block 3015 and the limit block 3014 are engaged, so that the first push rod 3012 drives the first transmission shaft 3011 to rotate.

[0071] Here, illustratively, the first transmission shaft 3011 and the gear 3013 are fixedly connected by key fitting, and the first transmission shaft 3011 and the first push rod 3012 are freely rotatably connected. Only when the lock head assembly 400 pushes the force in the first direction, the fixed block 3015 and the limit block 3014 on the first transmission shaft 3011 are engaged, so that the first push rod 3012 drives the first rotating shaft to rotate. When the lock head assembly 400 pushes the force in the second direction, the fixed block 3015 does not contact the limit block 3014. Therefore, the first rotating shaft and the first push rod 3012 are still in a free rotation state and do not affect the rotation position of the locking member 200.

[0072] In the above embodiment, the first direction refers to the direction in which the lock assembly 400 enters the slideway 101 from the opening 102, that is, Figure 1 The second direction is the direction in which the lock assembly 400 exits from the interior of the slideway 101 to the opening 102, that is, Figure 1 The B direction.

[0073] Figure 5 In the embodiment, the pushing force of the lock assembly 400 in the first direction causes the first push rod 3012 to rotate clockwise, and the first push rod 3012 drives the first transmission shaft 3011 to rotate clockwise. The gear 3013 on the first transmission shaft 3011 drives the transmission rod 303 to move to the right, thereby causing the locking member 200 connected to the transmission rod 303 to rotate counterclockwise, and the locking member 200 falls to block the slideway 101 to form a locked state. At this time, Figure 6 As shown, by adjusting the steel wire rope 900 to make the front beam 500 fall down, the locking head assembly 400 moves along the second direction until it engages with the locking member 200, thereby completing the locking of the locking member 200 and the locking head assembly 400.

[0074] Similarly, the second trigger member 302 includes a second transmission shaft 3021 and a second push rod 3022 sleeved on the second transmission shaft 3021, and the second transmission shaft 3021 is connected to the second tooth portion 3032; the second push rod 3022 is configured to drive the second transmission shaft 3021 to rotate under the pushing force of the lock assembly 400 in the first direction.

[0075] The above-mentioned second trigger member 302 is located on the side of the first trigger member 301 away from the opening 102. The maximum swing amplitude of the second trigger member 302 does not exceed the displacement path range of the lock assembly 400. That is, the lock assembly 400 does not cross the second trigger member 302 when pushing the second trigger member 302. Therefore, the second trigger member 302 does not need to be provided with the limit block 3014 and the fixed block 3015 of the first trigger member 301. It is sufficient as long as it can drive the transmission rod 303 to move left under the pushing force of the lock assembly 400 in the first direction.

[0076] Figure 7 In the process, the pushing force of the lock assembly 400 in the first direction causes the second push rod 3022 to rotate clockwise, which in turn drives the second transmission shaft 3021 to rotate clockwise. The gear member on the second transmission shaft 3021 drives the transmission rod 303 to move leftward, thereby causing the locking member 200, which is in transmission connection with the transmission rod 303, to rotate clockwise. The locking member 200 is lifted to clear the slideway 101, thus achieving the unlocked state. At this point, the front beam 500 is lowered by adjusting the wire rope 900, and the lock assembly 400 moves in the second direction until it clears the slideway 101, completing the separation of the lock assembly 400 from the anchoring device.

[0077] In the above embodiment, the second tooth portion 3032 actually includes a portion for cooperating with the gear part on the second transmission shaft 3021 and a portion for cooperating with the gear part on the rotating shaft of the locking member 200. Therefore, the second tooth portion 3032 can set the extension length according to the actual transmission ratio. For example, in the figure, the second tooth portion 3032 includes the left tooth portion and the right tooth portion of the transmission rod 303. In some replaceable embodiments, the upper end of the transmission rod 303 is provided with a complete second tooth portion 3032 extending along its own length direction, as long as it can cooperate with the gear part on the second transmission shaft 3021 and the gear part on the locking member 200 for transmission.

[0078] like Figure 2 As shown, in the embodiment of the present application, the locking member 200 adopts a safety hook that cooperates with the lock assembly 400. The locking member 200 includes a hook body 201 for clamping the lock assembly 400 and a clamping head 202 provided at the free end of the hook body. The mounting bracket 100 is provided with a concave clamping groove 106 on one side corresponding to the slide 101. The clamping head 202 is engaged with the clamping groove 106 to form a locked state of the locking member 200.

[0079] In the above-described embodiment, the hook body 201 of the locking member 200 is rotated by a rotating shaft passing through it. A gear is provided at one end of the rotating shaft passing through the hook body 201, and the gear engages with the second tooth portion 3032. The locking member 200 rotates counterclockwise until it engages with the groove of the mounting bracket 100. The groove of the mounting bracket 100 and the locking member 200 form a rigid support point, thereby ensuring the stable locking state of the locking member 200 and preventing the locking member 200 from being driven off the mounting bracket 100 by the lock head assembly 400.

[0080] It should be noted that the transmission ratios of the gear member on the rotating shaft of the locking member 200 and the second toothed portion 3032, the gear member on the first transmission shaft 3011 and the first toothed portion 3031, and the gear member on the second transmission shaft 3021 and the second toothed portion 3032 can all be flexibly designed based on the operating scenario. For example, the transmission ratio of the gear member on the rotating shaft of the locking member 200 and the second toothed portion 3032 is 3:1, and the transmission ratios of the gear member on the first transmission shaft 3011 and the first toothed portion 3031, and the transmission ratios of the gear member on the second transmission shaft 3021 and the second toothed portion 3032 are both 1:1. Of course, the design of the transmission ratios of the above-mentioned components needs to take into account the rotation speed of the locking member 200, the swing range of the first push rod 3012 and the second push rod 3022, etc. Generally, when the first transmission shaft 3011 and the second transmission shaft 3021 rotate 90°, the locking member 200 rotates 270°. This is illustrated in the examples of the present application.

[0081] As an alternative embodiment, the mounting bracket 100 is a double-layer plate-like structure, such as Figure 3As shown, the mounting bracket 100 includes two sets of overlapping rigid plates 108, which together form a slide 101. A groove is formed in the middle of the slide 101 formed by the two sets of rigid plates 108. The two sets of rigid plates 108 can be one-piece metal parts or metal structures formed by welding and bolting. The provision of two sets of rigid plates 108 can further enhance the overall structural strength of the mounting bracket 100 and ensure the locking force of the mounting bracket 100 and the lock assembly 400.

[0082] Based on the structure with two groups of rigid plates 108, the above-mentioned transmission rod 303 can also be set as two on both sides of the mounting bracket 100, and each transmission rod 303 is provided with a first tooth portion 3031 and a second tooth portion 3032. A gear is provided at both ends corresponding to the rotating shaft of the first transmission shaft 3011, the second transmission shaft 3021 and the locking member 200. The gear parts at the two ends corresponding to the rotating shaft of the first transmission shaft 3011, the second transmission shaft 3021 and the locking member 200 are respectively connected to the transmission rods 303 on both sides. This design can further improve the transmission stability of the first trigger member 301, the second trigger member 302 and the locking member 200.

[0083] like Figure 3 As shown, in some embodiments, a support platform 103 is provided at one end of the mounting bracket 100 close to the opening 102 of the slideway 101 , and the support platform 103 is used to support the locking member 200 so that the locking member 200 remains in an unlocked state.

[0084] The support platform 103 is used to support the locking member 200 and maintain it in the unlocked state. That is, in the initial state, the locking member 200 is placed on the support platform 103 and is triggered to rotate accordingly by the first trigger member 301 and the second trigger member 302. The support platform 103 can prevent the locking member 200 from accidentally swinging and rotating due to its own weight or equipment vibration, thereby reducing the risk of the locking member 200 being accidentally triggered and locked.

[0085] In some embodiments, a first detector 104 is provided on the support platform 103 for detecting whether the locking member 200 is in the unlocked state. A second detector 105 is provided on the side of the slide 101 facing away from the second trigger member 302, along the opening 102 of the slide 101, for detecting the extreme position of the lock assembly 400. The first detector 104 and the second detector 105 can employ sensor components capable of detecting component displacement in the related art, such as inductive laser sensors, but this is not an absolute limitation in the embodiments of the present application. The provision of the second detector 105 can prevent the lock assembly 400 from excessively displacing within the slide 101 and colliding with the mounting bracket 100, thereby preventing the lock assembly 400 from damaging the mounting bracket 100.

[0086] Furthermore, the first detection member 104 includes an unlocked state position detection member 1041 and a locked state position detection member 1042 located on the support platform 103. The unlocked state position detection member 1041 detects the position of the locking member 200 in the unlocked state, and the locked state position detection member 1042 is used to detect the position of the locking member 200 in the locked state. Both the unlocked state position detection member 1041 and the locked state position detection member 1042 can adopt an inductive laser sensor. When the locking member 200 is rotated to the locked position, the locked state position detection member 1042 is triggered to remind the operator that the locking member 200 is in the locked state.

[0087] In some embodiments, a gradually outward-expanding guide portion is further provided on one side of the mounting bracket 100 close to the opening 102 of the slide 101. The guide portion may be an outward-expanding open guide strip that gradually transitions to the opening 102 of the slide 101. The guide portion can compensate for the misalignment error of the lock head assembly 400 when entering the slide 101. The lock head assembly 400 enters the slide 101 through the guided transition of the guide portion.

[0088] like Figure 8 As shown, in some embodiments, the lock assembly 400 includes a lock body 401 and a lock fixing frame 402 on which the lock body 401 is mounted. One end of the lock fixing frame 402 is fixedly connected to the front beam 500. The lock fixing frame 402 is provided with a slide groove 403 extending in the height direction. The lock body 401 can be slidably constrained in the slide groove 403 of the lock fixing frame 402.

[0089] Since the displacement of the front beam 500 is actually an arc motion, the lock assembly 400 also has a certain arc motion during the displacement of the front beam 500. The slide groove 403 on the lock fixing frame 402 can compensate for the arc motion of the lock and ensure that the lock enters the slideway 101 normally in a straight line direction.

[0090] An exemplary use process of the anchoring device for fixing the pitching mechanism of the quay crane according to an embodiment of the present application is as follows:

[0091] In the initial state, if Figure 1 As shown, the locking member 200 is located on the support platform 103 and is in an unlocked state. The operator adjusts the wire rope 900 to lift the front beam 500. During the lifting process of the front beam 500, the lock head assembly 400 gradually approaches the slide 101 and enters the slide 101 through the guide part. The lock head assembly 400 continues to extend into the slide 101 along the first direction.

[0092] like Figure 5As shown, when the lock head assembly 400 touches the first push rod 3012 of the first trigger member 301, it drives the first push rod 3012 to rotate clockwise, and the first push rod 3012 drives the first transmission shaft 3011 to rotate clockwise. The gear 3013 on the first transmission shaft 3011 drives the transmission rod 303 to move rightward, and the second tooth portion 3032 of the transmission rod 303 cooperates with the locking member 200 and the second transmission shaft 3021, driving the locking member 200 to rotate counterclockwise and fall until it cooperates with the card slot 106 of the mounting bracket 100 to form a locked state. The locking member 200 triggers the first detection member 104 during the rotation process, reminding the operator that the locking member 200 is in the locked state. At this time, Figure 6 As shown, the operator adjusts the wire rope 900 to make the front beam 500 fall, and the lock head assembly 400 retreats along the second direction in the slideway 101 until it is engaged and locked with the locking member 200.

[0093] like Figure 7 As shown, when it is necessary to contact the locking of the lock head assembly 400 and the locking member 200, the operator adjusts the wire rope 900 to pull up the front beam 500, and the lock head assembly 400 continues to move forward in the first direction in the slide 101 until it pushes the second trigger member 302, and the second push rod 3022 of the second trigger member 302 rotates to drive the transmission rod 303 to move left, and the transmission rod 303 moves left to drive the first push rod 3012 and the lock member 200 to reset, and the lock member 200 triggers the first detection member 104 during the clockwise rotation process, reminding the operator that the lock member 200 is in the unlocked state, and the operator continues to adjust the wire rope 900 to make the front beam 500 fall, and the lock head assembly 400 disengages from the slide 101 to complete the unlocking.
