Safety devices and conveying equipment

[0001] This application claims priority to Chinese patent application No. 202422746590.4, filed on November 11, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of battery manufacturing technology, and more specifically, to a safety device and a conveying equipment. Background Technology

[0003] In the battery production process, cell pallet handling equipment plays a crucial role. It is responsible for the efficient and accurate handling and stacking of cell pallets on the production line, and is a key piece of equipment to ensure smooth production flow. The safety and stability of cell pallet handling equipment are directly related to production efficiency and product quality, and are also an important prerequisite for ensuring the safety of production personnel.

[0004] Currently, the anti-fall devices of battery cell pallet handling equipment have a lag, which may prevent timely measures from being taken in the early stages of abnormal speed, increasing the probability of accidents. Invention Overview

[0005] According to one aspect of this application, a safety device is provided for controlling the movement of a conveyor table.

[0006] The safety device includes:

[0007] A floating structure, the floating structure being slidably connected to a track of a frame, and the floating structure being capable of moving along the track of the frame;

[0008] A safety clamp, which is connected to the side of the floating structure closest to the frame;

[0009] A rope connection structure, one side of which is used to connect to the wire rope of the frame, and the other side of which is connected to the floating structure;

[0010] When the wire rope of the frame slacks or breaks, the floating structure can move and drive the safety clamp to close, so that the safety clamp can lock the track of the frame.

[0011] According to another aspect of this application, a conveying device is provided, including a frame, a conveying platform, and the aforementioned safety device; the conveying platform is slidably connected to a track of the frame and is capable of moving along the track, and the safety device is connected to the side of the conveying platform near the frame.

[0012] One technical advantage of the embodiments of this application is that:

[0013] The safety device includes a floating structure, a safety clamp, and a rope connection structure. The floating structure is slidably connected to the track of the frame and can move along the track of the frame. The safety clamp is connected to the side of the floating structure near the frame. One side of the rope connection structure is connected to the wire rope of the frame, and the other side of the rope connection structure is connected to the floating structure. When the wire rope of the frame slacks or breaks, the floating structure can move and drive the safety clamp to close, so that the safety clamp can lock the track of the frame.

[0014] In this way, when the steel wire rope of the frame becomes slack or breaks, the movement of the floating structure can drive the safety clamp to close quickly, so that the safety clamp can lock the track of the frame in time when an abnormality occurs, so that the connected conveyor can stop moving and avoid the risk of the conveyor tipping over.

It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0032] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0033] Technologies and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such technologies and equipment should be considered part of the specification.

[0034] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0036] As an introduction to this application, a fall protection device for a battery cell pallet handling equipment is introduced, which mainly relies on the linkage mechanism between a safety clamp and a speed limiter. The speed limiter, acting as a speed monitoring device, triggers the safety clamp when it detects that the equipment's ascending or descending speed exceeds a preset safety threshold, thereby achieving emergency braking and fall protection for the equipment. However, because the speed limiter only responds after a speed anomaly and there is a certain delay before it can activate the safety clamp to stop the fall, this lag may prevent timely action in the early stages of a speed anomaly, increasing the probability of accidents.

[0037] This application provides a safety device 100 for controlling the movement of a conveyor table 200. The conveyor table 200 is slidably connected to a track of a frame 300 and can move along the track. The safety device 100 is connected to the conveyor table 200 and can move with the conveyor table 200. In abnormal circumstances, the safety clamp 2 in the safety device 100 can close and lock the track of the frame 300, thereby stopping the movement of the conveyor table 200.

[0038] As shown in Figures 1 to 3, the safety device 100 provided in this application includes:

[0039] Floating structure 1 is used to slide on the track of the frame 300, and the floating structure 1 can move along the track of the frame 300.

[0040] Safety clamp 2 is connected to the side of floating structure 1 near frame 300;

[0041] Rope connection structure 3, one side of which is used to connect to the wire rope of frame 300, and the other side of rope connection structure 3 is connected to floating structure 1;

[0042] When the wire rope of the frame 300 slackens or breaks, the floating structure 1 can move and drive the safety clamp 2 to close, so that the safety clamp 2 can lock the track of the frame 300.

[0043] Specifically, the floating structure 1 is connected to the conveyor table 200 and can slide along the track of the frame 300 together with the conveyor table 200. The floating structure 1 may be equipped with slide rails or rollers that match the track of the frame 300 to ensure the smooth movement of the floating structure 1 on the track. The floating structure 1 may possess sufficient strength and rigidity to withstand the force generated when the safety clamp 2 closes.

[0044] As shown in Figures 1 to 3, the safety clamp 2 is connected to the side of the floating structure 1 closest to the track of the frame 300, i.e., the safety clamp 2 faces the track of the frame 300. When the wire rope of the frame 300 slackens or breaks, the safety clamp 2 can close and lock the track of the frame 300 under the action of the floating structure 1, thereby stopping the connected conveyor table 200 from moving. In the locked state, the safety clamp 2 maintains sufficient friction to prevent the conveyor table 200 from sliding along the track.

[0045] As shown in Figures 1 to 3, the rope connection structure 3 is used to connect the wire rope of the frame 300 to the safety device 100, so that the safety device 100 can monitor the state of the wire rope. Specifically, one side of the rope connection structure 3 can be connected to the wire rope of the frame 300 through a wire rope clamp, and the other side of the rope connection structure 3 is fixedly connected to the floating structure 1, so that the floating structure 1 can move accordingly when the wire rope of the frame 300 slacks or breaks.

[0046] When the wire rope of the frame 300 is in normal condition, the safety clamp 2 is in the open state and will not lock the track of the frame 300. At this time, the conveyor table 200 can drive the safety clamp 2 to move together.

[0047] 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 clamp 2 connected to it can approach the track of the frame 300 until it closes and locks. At this time, the locking mechanism of the safety clamp 2 will tightly grip the track of the frame 300, preventing it from sliding along the track, thereby stopping the connected conveyor table 200 from moving.

[0048] Therefore, when the wire rope of the frame 300 becomes slack or breaks due to wear, breakage, or operational errors, the safety device 100 of this embodiment can respond quickly, enabling the safety clamp 2 to close promptly and lock the track of the frame 300. This immediate response and automatic locking mechanism effectively prevents risks such as loss of control or fall of the conveyor table 200 due to wire rope failure.

[0049] Furthermore, the locking function of the safety clamp 2 not only prevents the conveyor platform 200 from falling, but also provides additional support and stability for the conveyor platform 200 in emergency situations. 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 this safety device 100.

[0050] In addition, the safety device 100 may also include a speed governor, a switch, and a controller. When the movement speed of the conveyor 200 exceeds the set speed of the speed governor, the switch is opened, and the safety clamp 2 can also be closed by the controller. In this way, dual triggering of the speed governor and the wire rope can be achieved, thereby improving the reliability of the safety device 100.

[0051] Optionally, the floating structure 1 includes a body 11 and a first connector 12, 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 clamp 2 is connected to the body 11.

[0052] When the wire rope of the frame 300 is slack or broken, the rope connection structure 3 can apply pressure to the second side, so that the first connector 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.

[0053] As shown in Figure 1, the floating structure 1 can be designed as a combination of the main body 11 and the first connecting member 12. The first connecting member 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 slackens or breaks, under the action of gravity, the rope connection structure 3 can quickly apply downward pressure to the second side of the first connecting member 12, causing the first connecting member 12 to rotate clockwise around the second side and drive the first side to rise along the track of the frame 300. This allows the first side to drive the connected safety clamp 2 to close and lock the track of the frame 300. This design optimizes the power transmission path and reduces the response time, allowing the safety clamp 2 to close more quickly to lock the track of the frame 300.

[0054] In this embodiment, the safety clamp 2 is connected to the main body 11, rather than directly to the rope connection structure 3 or the frame 300. This arrangement reduces locking instability caused by losses and uncertainties in the power transmission process. When the rope connection structure 3 drives the first connector 12, the main body 11, as a stable support point, ensures that the safety clamp 2 maintains the correct position and angle during closing, thereby enhancing the stability and reliability of the locking.

[0055] Furthermore, the combined design of the body 11 and the first connector 12 not only optimizes the power transmission path but also improves the overall strength and durability of the safety device 100. The body 11, as the main load-bearing component of the floating structure 1, can withstand the enormous force when the safety clamp 2 closes, while the first connector 12 is responsible for transmitting power from the rope connection structure 3 to the body 11. This division of labor allows each component to fully utilize its advantages, thereby improving the overall strength and durability of the safety device 100.

[0056] In another embodiment, the first connector 12 may further include multiple connecting rods with transmission connections, wherein the connecting rods connected to the rope connection structure 3 move in the opposite direction to the connecting rods connected to the safety clamp 2. When the wire rope of the frame 300 slackens or breaks, the connecting rods connected to the rope connection structure 3 can move downwards, thereby driving the connecting rods connected to the safety clamp 2 to move upwards, which in turn can drive the safety clamp 2 to close and lock the track of the frame 300.

[0057] In another embodiment, a spring can be installed between the floating structure 1 and the track of the frame 300, and the spring is normally in a compressed state. When the wire rope of the frame 300 slackens or breaks, the elastic force of the spring can drive the floating structure 1 to rise and drive the safety clamp 2 to close to lock the track of the frame 300.

[0058] Optionally, it also includes a first spring 4, one end of which is connected to the rope connection structure 3, the other end of which is connected to the second side, and the first spring 4 is in a compressed state;

[0059] When the wire rope of frame 300 slackens or breaks, the first spring 4 can elastically reset and apply pressure to the second side.

[0060] As shown in Figures 1 and 2, when the wire rope of the frame 300 is in normal condition, the first spring 4 is compressed by the rope connection structure 3. At this time, the safety clamp 2 is in the open state and will not lock the track of the frame 300. The conveyor table 200 can drive the safety clamp 2 to move together.

[0061] When the wire rope of the frame 300 slackens or breaks, 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 clamp 2 to close and lock. At this time, the locking mechanism of the safety clamp 2 will tightly bite the track of the frame 300 to prevent it from sliding along the track, thereby stopping the connected conveyor table 200 from moving. In this way, the rotation of the first connecting member 12 can be driven by the elastic force of the first spring 4, and the state of the safety clamp 2 can be conveniently switched.

[0062] Optionally, it also includes a sleeve 5, with a connecting groove on the second side, the sleeve 5 being connected to the connecting groove, and the first spring 4 passing through the sleeve 5.

[0063] As shown in Figures 1 and 2, the sleeve 5 has a protrusion that passes through the connecting groove to connect the sleeve 5 to the second side. When the wire rope of the frame 300 slackens or breaks, the first spring 4 can elastically reset and apply pressure to the second side through the sleeve 5, causing the first connecting piece 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 clamp 2 to close and lock. Furthermore, the sleeve 5 can also protect the first spring 4 that passes through it.

[0064] Optionally, a second spring 6 is also included, one side of which is connected to the first side, and the other side of which is used to connect to the conveyor table 200, and the second spring 6 is in a stretched state.

[0065] As shown in Figure 8, when the wire rope of the frame 300 is in normal condition, 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 the open state and will not lock the track of the frame 300. The conveyor table 200 can drive the safety clamp 2 to move together.

[0066] When the wire rope of the frame 300 slackens or breaks, 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 clamp 2 to close and lock. At this time, under the action of elastic force, the second spring 6 can elastically reset, thereby ensuring the reliability of the rotation of the first connecting member 12.

[0067] Optionally, it also includes a second connector 7, one side of which is connected to the floating structure 1, and the other side of which is connected to the safety clamp 2.

[0068] As shown in Figures 1 and 2, the design of the second connector 7 provides a connection point between the floating structure 1 and the safety clamp 2, which not only enhances the connection strength between the two but also improves the overall structural stability. In emergency situations, such as when the wire rope of the frame 300 becomes slack or breaks, the second connector 7 ensures that the safety clamp 2 closes stably and reliably, preventing safety hazards caused by loose or broken connections. The second connector 7 can be a connecting plate for easy assembly.

[0069] By incorporating the second connector 7, the floating structure 1, when powered by the rope connection structure 3, can more smoothly and accurately push the safety clamp 2 to close, thereby optimizing the power transmission path and reducing the problem of poor locking effect caused by power dispersion or poor transmission. Furthermore, the second connector 7 also acts as a buffer and shock absorber, protecting the floating structure 1 and the safety clamp 2 from impact damage caused by sudden power changes.

[0070] Optionally, it also includes two linkage structures 8. The number of safety clamps 2, floating structure 1 and rope connection structure 3 is two. The linkage structure 8 is used to drive the two safety clamps 2 to close together to lock the track of the frame 300.

[0071] As shown in Figures 8 to 11, each side of the conveyor platform 200 is connected to a locking group consisting of a safety clamp 2, a floating structure 1, a rope connection structure 3, and a linkage structure 8. In case of an abnormality, the safety clamps 2 in both locking groups can close and 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, thus avoiding risks such as the conveyor platform 200 tipping over.

[0072] Among them, the linkage structure 8 can be a multi-link structure composed of multiple transmission-connected links, and the two linkage structures 8 can be connected by transmission through links, rotating shafts 9, etc.

[0073] Optionally, it also includes a rotating shaft 9, with a linkage structure 8 connected to each end of the rotating shaft 9, and each linkage structure 8 connected to a safety clamp 2. As shown in Figure 8, the conveyor table 200 has a through hole, through which the rotating shaft 9 is inserted and connected to a linkage structure 8 at each end, so that the linkage structures 8 on both sides can be connected to drive each other, thereby realizing the synchronous control of the two safety clamps 2, and improving the reliability and controllability of the safety device 100.

[0074] Optionally, the floating structure 1 has guide wheels 13 for sliding connection to the track of the frame 300. As shown in Figure 8, the floating structure 1 can be designed with guide wheels 13, i.e., rollers, that match the track of the frame 300 to ensure the smoothness of the floating structure 1's movement on the track.

[0075] This application also provides a conveying device, including a frame 300, a conveying table 200 and a safety device 100, wherein the conveying table 200 is slidably connected to the track of the frame 300 and is capable of moving along the track, and the safety device 100 is connected to the side of the conveying table 200 near the frame 300.

[0076] As shown in Figures 4 to 7, the conveyor 200 is slidably connected to the track of the frame 300 and can move along the track of the frame 300. The safety device 100 is connected to the conveyor 200 and can move with the conveyor 200. The conveying equipment can be a battery cell tray handling device, used to handle battery cell trays.

[0077] When the wire rope of the frame 300 becomes slack or breaks due to wear, breakage, or operational errors, the safety device 100 can respond quickly, enabling the safety clamp 2 to close promptly and lock the track of the frame 300. This immediate response and automatic locking mechanism effectively prevents the risk of the conveyor table 200 going out of control or falling due to wire rope failure.

[0078] The above embodiments mainly describe 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. For the sake of brevity, they will not be elaborated here.
