A stacker crane loading platform and stacker crane

Abstract

This utility model discloses a stacker crane loading platform and a stacker crane. During cargo handling, the entire frame rises and falls along an external lifting guide rail. When the frame malfunctions or overspeeds, the wire rope of the external speed limiter stops rotating, but the frame continues to descend, causing the connecting rod assembly to actuate the connecting bar. If the connecting bar exceeds the detection range of the detection element, the detection element sends a signal to the safety clamp body. Upon receiving the signal, the safety clamp body immediately clamps the external lifting guide rail to prevent the frame from continuing to descend, thus achieving emergency braking. During normal frame lifting, two sets of follower motors roll along both sides of the external lifting guide rail, reducing friction between the safety clamp body and the external lifting guide rail, which facilitates overall movement.

Description

Technical Field

[0001] This utility model relates to the field of warehousing and logistics, specifically to a stacker crane loading platform and a stacker crane. Background Technology

[0002] Stacker cranes play a crucial role in warehousing and logistics systems and automated production lines. Ensuring the stability and safety of stacker cranes during high-speed operation is a critical issue. Safety clamps are essential for the safe operation of the stacker crane's loading platform. In the event of an abnormality or overspeeding, the safety clamps can urgently clamp the lifting guide rails to brake the platform and prevent further descent. However, in existing technology, during normal lifting, the safety clamps and lifting guide rails are in a sliding connection, resulting in significant friction and hindering movement. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a stacker crane loading platform and a stacker crane, which can solve the problem of excessive friction between the safety clamp and the lifting guide rail when the stacker crane moves in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: On the one hand, a stacker crane loading platform is provided, including a frame and a safety gear assembly, a detection component, and a linkage assembly, all mounted on the frame. The safety gear assembly includes a safety gear body and several followers. The followers are rotatably mounted on the safety gear body and are divided into two groups. The two groups of followers are respectively rotatably connected to both sides of an external lifting guide rail. A connecting bar is movably provided on the safety gear body. The detection component is used to detect the position of the connecting bar and send a signal to the safety gear body. The linkage assembly is connected to the wire rope of an external speed limiter and is used to actuate the connecting bar.

[0005] As a further improvement to the above technical solution, the detection element includes a proximity switch, which is fixed on the frame and has its sensing end facing the connecting strip. The output end of the proximity switch is unidirectionally electrically connected to the input end of the safety clamp body.

[0006] As a further improvement to the above technical solution, four follower devices are provided, two of which are located above the safety clamp body and the other two are located below the safety clamp body.

[0007] As a further improvement to the above technical solution, the linkage assembly includes a safety clamp pull rod, a connecting shaft, and a swing arm. One end of the safety clamp pull rod is connected to the connecting bar, the other end of the safety clamp pull rod is hinged to one end of the connecting shaft, the other end of the connecting shaft is hinged to one end of the swing arm, and the other end of the swing arm is fixed to the frame. The safety clamp pull rod is connected to the wire rope of the external speed limiter.

[0008] As a further improvement to the above technical solution, the frame is provided with a vertical slide rail, and the safety clamp lever is slidably connected to the slide rail via a slider.

[0009] As a further improvement to the above technical solution, a connecting groove is provided below the connecting strip, and one end of the safety clamp lever is fixedly connected in the connecting groove.

[0010] As a further improvement to the above technical solution, the safety clamp body is provided with a horizontal guide rail, and the frame is provided with a horizontal slider, with the horizontal guide rail slidably connected to the horizontal slider.

[0011] As a further improvement to the above technical solution, two horizontal guide rails are provided, which are respectively connected to the upper and lower ends of the safety clamp body. Two horizontal sliders are provided on the frame, and the two horizontal guide rails are slidably connected to the two horizontal sliders respectively.

[0012] On the other hand, a stacker crane is provided, including a lifting guide rail, a speed limiter, and the aforementioned stacker crane loading platform. Two sets of the aforementioned follower are respectively tumblingly connected to both sides of the lifting guide rail, and the wire rope of the speed limiter is connected to the connecting rod assembly.

[0013] As a further improvement to the above technical solution, the lifting guide rail is a T-shaped guide rail.

[0014] The beneficial effects of this invention are as follows: When transporting goods, the entire frame moves up and down along the external lifting guide rail. When the frame malfunctions or overspeeds, the wire rope of the external speed limiter stops rotating, but the frame continues to descend, causing the linkage assembly to move the connecting bar. If the connecting bar exceeds the detection range of the detection element, the detection element sends a signal to the safety clamp body. Upon receiving the signal, the safety clamp body immediately clamps the external lifting guide rail to prevent the frame from continuing to descend, thus achieving emergency braking. During normal frame lifting, the two sets of follower motors roll along both sides of the external lifting guide rail, reducing friction between the safety clamp body and the external lifting guide rail, which facilitates overall movement.

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0024] Please see Figure 1-2A preferred embodiment of this utility model provides a stacker crane loading platform, including a frame 1 and a safety clamp assembly 2, a detection element 3, and a linkage assembly 4, all mounted on the frame 1. The safety clamp assembly 2 includes a safety clamp body 21 and several followers 22. The followers 22 are rotatably mounted on the safety clamp body 21 and are divided into two groups. The two groups of followers 22 are respectively rotatably connected to both sides of an external lifting guide rail. A connecting bar 23 is movably disposed on the safety clamp body 21. The detection element 3 is used to detect the position of the connecting bar 23 and send a signal to the safety clamp body 21. The linkage assembly 4 is connected to the wire rope of an external speed limiter and is used to actuate the connecting bar 23. During cargo handling, the frame 1 moves up and down along the external lifting guide rail. When the frame 1 malfunctions or overspeeds, the wire rope of the external speed limiter stops rotating. However, the frame 1 continues to descend, causing the linkage assembly 4 to move the connecting bar 23. The connecting bar 23 then exceeds the detection range of the detection element 3. At this point, the detection element 3 sends a signal to the safety clamp body 21. Upon receiving the signal, the safety clamp body 21 immediately clamps the external lifting guide rail to prevent the frame 1 from continuing to descend, thus achieving emergency braking. During normal lifting of the frame 1, the two sets of follower motors 22 roll along both sides of the external lifting guide rail, reducing friction between the safety clamp body 21 and the external lifting guide rail, which facilitates overall movement.

[0025] The detection component 3 includes a proximity switch 31, which is fixed to the frame 1 with its sensing end facing the connecting bar 23. The output end of the proximity switch 31 is unidirectionally electrically connected to the input end of the safety clamp body 21. When the connecting bar 23 is moved, the proximity switch 31 can detect the change in the connecting bar 23 and then send a signal to the safety clamp body 21. The proximity switch 31 does not need to have direct mechanical contact with the connecting bar 23 and has high repeatability and reliability.

[0026] In this embodiment, four follower 22s are provided, two of which are located above the safety clamp body 21 and the other two are located below the safety clamp body 21. Both the upper and lower ends of the safety clamp body 21 are connected to the external lifting guide rail by the follower 22, which further facilitates the follow-up of the safety clamp body 21 and thus facilitates the movement of the overall frame 1.

[0027] The linkage assembly 4 includes a safety clamp lever 41, a connecting shaft 42, and a swing arm 43. One end of the safety clamp lever 41 is connected to the connecting bar 23, and the other end of the safety clamp lever 41 is hinged to one end of the connecting shaft 42. The other end of the connecting shaft 42 is hinged to one end of the swing arm 43, and the other end of the swing arm 43 is fixed to the frame 1. The safety clamp lever 41 is connected to the wire rope of the external speed limiter. When the overall moving speed of the frame 1 is too fast, the wire rope of the external speed limiter can pull the safety clamp lever 41. At this time, both the connecting shaft 42 and the swing arm 43 rotate, and the frame 1 continues to move, thereby driving the safety clamp lever 41 to move the connecting bar 23 and triggering the braking signal.

[0028] The frame 1 is equipped with a vertical slide rail 11, and the safety clamp lever 41 is slidably connected to the slide rail 11 via a slider 12. When the wire rope of the external speed limiter pulls the safety clamp lever 41, the frame 1 drives the slide rail 11 to move, and the slide rail 11 slides relative to the slider 12. The cooperation between the two can play a guiding role to limit the movement path of the safety clamp lever 41.

[0029] Please see Figure 3-4 A connecting groove 231 is provided below the connecting bar 23. One end of the safety clamp lever 41 is fixedly connected in the connecting groove 231. The connecting groove 231 facilitates the fixing of the connecting bar 23 and the safety clamp lever 41, making the connection between the two more secure.

[0030] The safety clamp body 21 is equipped with a horizontal guide rail 13, and the frame 1 is equipped with a horizontal slider 14. The horizontal guide rail 13 is slidably connected to the horizontal slider 14. Under the cooperation of the horizontal guide rail 13 and the horizontal slider 14, the safety clamp body 21 can move in the horizontal direction. When the external lifting guide rail wobbles horizontally, the safety clamp body 21 can move horizontally accordingly, so that the follower 22 can be tightly attached to both sides of the external lifting guide rail.

[0031] In this embodiment, two horizontal guide rails 13 are provided, and the two horizontal guide rails 13 are respectively connected to the upper and lower ends of the safety clamp body 21. Two horizontal sliders 14 are provided on the frame 1, and the two horizontal guide rails 13 are slidably connected to the two horizontal sliders 14 respectively. The upper and lower ends of the safety clamp body 21 can move synchronously, which further facilitates the cooperation between the follower 22 at the upper and lower ends and the external lifting guide rail.

[0032] Please see Figure 3The preferred embodiment of this utility model also provides a stacker crane, including a lifting guide rail 5, a speed limiter, and a stacker crane loading platform as described in the above embodiment. Two sets of follower 22 are respectively rolledly connected to both sides of the lifting guide rail 5. The wire rope of the speed limiter is connected to the connecting rod assembly 4. Specifically, the wire rope of the speed limiter is connected to the safety clamp pull rod 41. During the normal lifting and lowering process of the frame 1, the two sets of follower 22 can roll along both sides of the lifting guide rail 5, reducing the friction between the safety clamp body 21 and the lifting guide rail 5, which is beneficial to the overall movement.

[0033] In this embodiment, the lifting guide rail 5 is a T-shaped guide rail, which has extremely high bending strength and rigidity, making it suitable for bearing heavy loads and avoiding significant deformation or vibration.

[0034] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
