[0002] In the battery production process, cell tray handling equipment plays a crucial role. Responsible for the efficient and accurate handling and stacking of cell trays on the production line, it is key to ensuring a smooth production process. The safety and stability of cell tray handling equipment are directly related to production efficiency and product quality, and are also crucial for ensuring the safety of production personnel.

[0003] Currently, fall prevention devices for battery cell pallet handling equipment primarily rely on a linkage mechanism between a safety clamp and a speed limiter. The speed limiter, a speed monitoring device, triggers the safety clamp when it detects the equipment's ascent or descent speed exceeds a preset safety threshold, thereby providing emergency braking and fall prevention.

[0004] However, since the speed limiter needs to respond after the speed abnormality occurs and there is a certain delay before the safety gear is activated to prevent the fall, this lag may result in the inability to take timely measures at the initial stage of the speed abnormality, increasing the probability of accidents.

[0042] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0043] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0044] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0045] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0046] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0047] The present invention provides a safety device 100 for controlling the movement of a conveyor platform 200. The conveyor platform 200 is slidably connected to a track of a frame 300 and is capable of moving along the track. The safety device 100 is connected to the conveyor platform 200 and can move with the conveyor platform 200. In the event of an abnormality, the safety clamp 2 in the safety device 100 can close and lock the track of the frame 300, thereby stopping the conveyor platform 200.

[0048] like Figures 1 to 3 As shown, the safety device 100 provided by the present invention includes:

[0049] A floating structure 1, wherein the floating structure 1 is configured to be slidably connected to a rail of the rack 300 and capable of moving along the rail of the rack 300;

[0050] a safety gear 2 connected to a side of the floating structure 1 close to the frame 300;

[0051] a rope connection structure 3, one side of the rope connection structure 3 being connected to the steel wire rope of the frame 300, and the other side of the rope connection structure 3 being connected to the floating structure 1;

[0052] When the steel wire rope of the frame 300 is loose or disconnected, the floating structure 1 can move and drive the safety gear 2 to close, so that the safety gear 2 can lock the track of the frame 300.

[0053] Specifically, the floating structure 1 is connected to the conveyor platform 200 and can slide along the track of the frame 300. The floating structure 1 can be designed with slide rails or rollers that match the track of the frame 300 to ensure smooth movement of the floating structure 1 on the track. The floating structure 1 also needs to have a certain strength and rigidity to withstand the forces generated when the safety gear 2 is closed.

[0054] like Figures 1 to 3 As shown, the safety gear 2 is connected to the side of the floating structure 1 closest to the track of the frame 300, that is, the safety gear 2 faces the track of the frame 300. If the wire rope of the frame 300 slackens or breaks, the safety gear 2, driven by the floating structure 1, closes and locks the track of the frame 300, stopping the movement of the connected conveyor platform 200. In this locked state, the safety gear 2 maintains sufficient friction to prevent the conveyor platform 200 from sliding along the track. The locking principle of the safety gear 2 is conventional in the art and will not be elaborated here.

[0055] like Figures 1 to 3As shown, the rope connection structure 3 is used to connect the steel wire rope of the frame 300 to the safety device 100, so that the safety device 100 can monitor the status of the steel wire rope. Specifically, one side of the rope connection structure 3 can be connected to the steel wire rope of the frame 300 via a wire rope clamp, and the other side of the rope connection structure 3 is fixedly connected to the floating structure 1. When the steel wire rope of the frame 300 is loose or disconnected, the floating structure 1 can move accordingly.

[0056] When the steel wire rope of the rack 300 is in a normal state, the safety clamp 2 is in an open state and will not lock the track of the rack 300. At this time, the conveying platform 200 can drive the safety clamp 2 to move together.

[0057] When the wire rope of the frame 300 slackens or breaks, the rope connection structure 3 releases the floating structure 1, allowing it to move. As the floating structure 1 moves, the safety gear 2 connected to it approaches the rails of the frame 300 until it closes and locks. At this point, the locking mechanism of the safety gear 2 firmly engages the rails of the frame 300, preventing it from sliding along the rails and thus stopping the movement of the connected conveyor platform 200.

[0058] Thus, when the steel wire rope of the rack 300 becomes loose or disconnected due to wear, breakage, or operational error, the safety device 100 of the present invention can respond quickly, allowing the safety clamp 2 to close in time and tightly lock the track of the rack 300. This immediate response and automatic locking mechanism effectively prevents the risk of the conveyor platform 200 losing control or falling due to steel wire rope failure.

[0059] Furthermore, the locking action of the safety gear 2 not only prevents the conveyor platform 200 from falling, but also provides additional support and stability for the conveyor platform 200 in an emergency. This helps reduce secondary injuries or losses that may be caused by wire rope failure, and also improves the conveying reliability and controllability of the conveying equipment equipped with the safety gear 100.

[0060] In addition, the safety device 100 may also include a speed limiter, a switch, and a controller. When the speed of the conveyor 200 exceeds the set speed of the speed limiter, the switch is opened, and the safety clamp 2 can also be controlled by the controller to close. In this way, the speed limiter and the wire rope can be triggered simultaneously, thereby improving the reliability of the safety device 100.

[0061] Optionally, the floating structure 1 includes a body 11 and a first connector 12, wherein a first side of the first connector 12 is connected to the body 11, a second side of the first connector 12 is connected to the rope connection structure 3, and the safety gear 2 is connected to the body 11;

[0062] When the steel wire rope of the frame 300 is loose or disconnected, the rope connecting structure 3 can apply pressure to the second side, so that the first connecting member 12 can rotate around the second side and drive the first side to rise, so that the first side drives the safety clamp 2 to close.

[0063] like Figure 1 As shown, the floating structure 1 can be designed as a combination of a body 11 and a first connector 12. The first connector 12 is connected to the steel wire rope of the frame 300 via a rope connection structure 3. When the steel wire rope of the frame 300 becomes slack or disconnected, the rope connection structure 3, under the action of gravity, can quickly apply downward pressure to the second side of the first connector 12, causing the first connector 12 to rotate clockwise about the second side and drive the first side up along the track of the frame 300. This allows the first side to drive the connected safety gear 2 to close and lock the track of the frame 300. This design optimizes the power transmission path and reduces response time, allowing the safety gear 2 to close more quickly to lock the track of the frame 300.

[0064] By connecting the safety gear 2 to the body 11, rather than directly to the rope connection structure 3 or the frame 300, the present invention reduces the problem of locking instability caused by losses and uncertainties in power transmission. When the rope connection structure 3 drives the first connector 12 to move, the body 11 acts as a stable support point, ensuring that the safety gear 2 maintains the correct position and angle during the closing process, thereby enhancing the stability and reliability of the locking.

[0065] Furthermore, the combined design of the main body 11 and first connector 12 not only optimizes the power transmission path but also enhances the strength and durability of the overall safety device 100. As the primary load-bearing component of the floating structure 1, the main body 11 can withstand the tremendous force exerted by the closing of the safety gear 2, while the first connector 12 is responsible for transmitting power from the rope connection structure 3 to the main body 11. This collaborative design allows each component to fully utilize its strengths, thereby enhancing the strength and durability of the overall safety device 100.

[0066] In another embodiment, the first connecting member 12 may further include a plurality of connecting rods connected in a transmission manner, wherein the connecting rod connected to the rope connecting structure 3 moves in the opposite direction to the connecting rod connected to the safety gear 2. When the wire rope of the frame 300 is loose or disconnected, the connecting rod connected to the rope connecting structure 3 can move downward, driving the connecting rod connected to the safety gear 2 to move upward, thereby driving the safety gear 2 to close and lock the track of the frame 300.

[0067] In yet another embodiment, a spring may be provided between the floating structure 1 and the rails of the frame 300. Normally, the spring is compressed. When the wire rope of the frame 300 slackens or breaks, the spring's elastic force can cause the floating structure 1 to rise and the safety gear 2 to close, locking the rails of the frame 300.

[0068] Optionally, it further includes a first spring 4, one end of the first spring 4 is connected to the rope connection structure 3, the other end of the first spring 4 is connected to the second side, and the first spring 4 is in a compressed state;

[0069] When the steel wire rope of the frame 300 is loose or disconnected, the first spring 4 can elastically return to its original position and apply pressure to the second side.

[0070] like Figure 1 and Figure 2 As shown, when the wire rope of the rack 300 is in a normal state, the first spring 4 is compressed by the rope connection structure 3. At this time, the safety clamp 2 is in an open state and will not lock the track of the rack 300. The conveyor platform 200 can drive the safety clamp 2 to move together.

[0071] When the wire rope of the frame 300 slackens or breaks, the first spring 4 elastically resets and applies pressure to the second side, causing the first connector 12 to rotate clockwise around the second side and lift the first side. This lift causes the safety gear 2 to close and lock. At this point, the locking mechanism of the safety gear 2 firmly engages the rails of the frame 300, preventing it from sliding along the rails and halting the movement of the connected conveyor platform 200. This elastic force of the first spring 4 drives the rotation of the first connector 12, enabling convenient switching between the safety gear 2's states.

[0072] Optionally, a sleeve 5 is further included, a connecting groove is opened on the second side, the sleeve 5 is connected to the connecting groove, and the first spring 4 is inserted into the sleeve 5 .

[0073] like Figure 1 and Figure 2 As shown, the sleeve 5 has a protrusion that penetrates into the connecting groove to connect the sleeve 5 to the second side. When the wire rope of the frame 300 is loose or disconnected, the first spring 4 can elastically reset and apply pressure to the second side through the sleeve 5, causing the first connecting member 12 to rotate clockwise around the second side and drive the first side to rise. The rise of the first side can drive the safety gear 2 to close and lock. The sleeve 5 also provides protection for the first spring 4 inserted therein.

[0074] Optionally, a second spring 6 is further included, one side of the second spring 6 is connected to the first side, the other side of the second spring 6 is used to connect to the conveying platform 200, and the second spring 6 is in a stretched state.

[0075] like Figure 8 As shown, when the wire rope of the rack 300 is in a normal state, the first spring 4 is compressed by the rope connection structure 3, and the second spring 6 is stretched by the floating structure 1. At this time, the safety clamp 2 is in an open state and will not lock the track of the rack 300. The conveyor platform 200 can drive the safety clamp 2 to move together.

[0076] When the steel wire rope of the frame 300 is loose or disconnected, the first spring 4 can elastically reset and apply pressure to the second side, causing the first connecting member 12 to rotate clockwise around the second side and drive the first side to rise. The rise of the first side can drive the safety gear 2 to close and lock. At this time, under the action of the elastic force, the second spring 6 can elastically reset, thereby ensuring the reliability of the rotation of the first connecting member 12.

[0077] Optionally, a second connecting member 7 is further included, one side of the second connecting member 7 is connected to the floating structure 1 , and the other side of the second connecting member 7 is connected to the safety gear 2 .

[0078] like Figure 1 and Figure 2 As shown, the design of the second connector 7 provides a connection point between the floating structure 1 and the safety gear 2, which not only strengthens the connection strength between the two but also improves the stability of the entire structure. In emergency situations, such as when the wire rope of the frame 300 becomes loose or disconnected, the second connector 7 ensures the stable and reliable closure of the safety gear 2, preventing safety hazards caused by loose or broken connections. The second connector 7 can be a connecting plate to facilitate assembly.

[0079] The second connector 7 allows the floating structure 1 to more smoothly and accurately push the safety gear 2 to close when receiving power from the rope connection structure 3, thereby optimizing the power transmission path and reducing the problem of poor locking effect caused by power dispersion or poor power transmission. Furthermore, the second connector 7 provides a buffering and shock-absorbing function, protecting the floating structure 1 and safety gear 2 from impact damage caused by sudden changes in power.

[0080] Optionally, two linkage structures 8 are further included. The number of the safety clamp 2, the floating structure 1 and the rope connection structure 3 is two. The linkage structure 8 is used to drive the two safety clamps 2 to close to jointly lock the track of the frame 300.

[0081] like Figures 8 to 11As shown, a locking group formed by a safety clamp 2, a floating structure 1, a rope connection structure 3 and a linkage structure 8 is connected to each side of the conveyor platform 200. When an abnormality occurs, the safety clamps 2 in the two locking groups can be closed and jointly lock the track of the frame 300 from both sides, thereby stopping the movement of the conveyor platform 200 and stably fixing the conveyor platform 200 on the track of the frame 300, avoiding the risk of the conveyor platform 200 tipping over.

[0082] The linkage structure 8 may be a multi-link structure composed of a plurality of transmission-connected links, and two linkage structures 8 may be transmission-connected via links, rotating shafts 9 and the like.

[0083] Optionally, it further comprises a rotating shaft 9, with both ends of the rotating shaft 9 connected to a linkage structure 8, and each linkage structure 8 is connected to a safety gear 2. Figure 8 As shown, the conveying platform 200 is provided with a through hole, the rotating shaft 9 is passed through the through hole and a linkage structure 8 is connected at both ends, so that the linkage structures 8 on both sides can be connected by transmission, thereby realizing synchronous control of the two safety clamps 2 and improving the reliability and controllability of the safety device 100.

[0084] Optionally, the floating structure 1 has guide wheels 13, and the guide wheels 13 are used to be slidably connected to the rails of the frame 300. Figure 8 As shown, the floating structure 1 may be designed with guide wheels 13 , ie, rollers, that match the rails of the frame 300 , so as to ensure the smooth movement of the floating structure 1 on the rails.

[0085] The present invention also provides a conveying device, including a frame 300, a conveying platform 200 and the safety device 100, wherein the conveying platform 200 is slidably connected to the track of the frame 300 and can move along the track, and the safety device 100 is connected to a side of the conveying platform 200 close to the frame 300.

[0086] like Figures 4 to 7 As shown, the conveyor platform 200 is slidably connected to the track of the rack 300 and can move along the track of the rack 300, and the safety device 100 is connected to the conveyor platform 200 and can move with the conveyor platform 200. The conveying equipment can be a battery cell tray handling equipment, which is used to handle the battery cell tray.

[0087] When the wire rope of the rack 300 becomes loose or disconnected due to wear, breakage, or operational errors, the safety device 100 can respond quickly, allowing the safety clamp 2 to close in time and tightly lock the track of the rack 300. This immediate response and automatic locking mechanism effectively prevents the risk of the conveyor platform 200 losing control or falling due to wire rope failure.

[0088] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

Those skilled in the art will appreciate that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention.
