[0002] In the chemical industry, woven bag packaging is a common form of packaging for chemical products. These products are usually stacked on pallets for transfer and storage. This practice not only saves storage space but also greatly improves the efficiency of cargo transfer, which helps to improve the efficiency of enterprises.

[0003] However, in practice, due to non-standard stacking of goods, issues such as stack tipping, bag slippage, and scattering often occur during stacking and transportation. These problems not only pose hidden dangers to the company's production and operation but may also increase equipment failure rates, causing significant inconvenience. This is especially true when the packaging bags are very smooth and the products are granular and highly fluid, making stack tipping and bag slippage more likely during handling. Therefore, we have made improvements and proposed an anti-falling clamping device for the stacker crane's loading platform. Utility Model Content

[0004] The purpose of this utility model is to address the existing problems of goods falling over, slipping, and scattering during stacking and transportation.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] As described in the background section, due to non-standard stacking of goods, problems such as stacking over, slipping, and scattering often occur during the stacking and transportation of goods. These problems not only pose hidden dangers to the production and operation of enterprises, but may also lead to an increase in equipment failure rate, which is very inconvenient. Especially when the packaging bags of goods are very smooth and the products are granular and highly fluid, stacking over and slipping are more likely to occur during handling.

[0032] To solve this technical problem, this utility model provides an anti-falling clamping device for a stacker crane loading platform.

[0033] For details, please refer to Figures 1-6 The anti-fall clamping device used for the stacker crane loading platform specifically includes:

[0034] Two clamping structures are used in conjunction with each other. Each clamping structure includes a mounting frame 1. Two support seats 101 are mounted on the side of the mounting frame 1. Each support seat 101 is hinged to a first L-shaped plate 103. Each first L-shaped plate 103 is hinged to a connecting plate 105. A clamping plate assembly is connected between the two connecting plates 105. A linkage rod 106 is also hinged between the two first L-shaped plates 103. A driving part is also provided on the mounting frame 1. The driving part is used to drive the first L-shaped plate 103 to rotate so as to realize the movement of the clamping plate assembly.

[0035] This utility model provides an anti-fall clamping device for a stacker crane's loading platform. Through this clamping device, during the stacker crane's handling of palletized goods, the first L-shaped plate 103 is driven to rotate via a drive unit. The first L-shaped plate 103, connecting plate 105, and linkage rod 106 cooperate to drive the clamping plate assembly to move, effectively clamping and fixing the goods. This reduces the risk of goods tipping over, slipping, or scattering during handling, improving safety. The clamping device effectively restrains the displacement of goods, especially for goods with unstable centers of gravity or loose packaging, reducing swaying and ensuring stability during handling.

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0038] 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 further defined and explained in subsequent figures.

[0039] Example 1, please refer to Figures 1-6 An anti-fall clamping device for a stacker crane loading platform includes two clamping structures that cooperate with each other. Each clamping structure includes a mounting frame 1. Two support seats 101 are mounted on the side of the mounting frame 1. Each support seat 101 is hinged to a first L-shaped plate 103. Each first L-shaped plate 103 is hinged to a connecting plate 105. A clamping plate assembly is connected between the two connecting plates 105. A linkage rod 106 is also hinged between the two first L-shaped plates 103. A driving part is also provided on the mounting frame 1. The driving part is used to drive the first L-shaped plate 103 to rotate so as to realize the movement of the clamping plate assembly. This application utilizes a clamping device that, during the handling of palletized goods by a stacker crane, drives the first L-shaped plate 103 to rotate via a drive unit. The first L-shaped plate 103, connecting plate 105, and linkage rod 106 cooperate to drive the clamping plate assembly to move, thereby effectively clamping and securing the goods. This reduces the risk of goods tipping over, slipping, or scattering during handling, improving safety. The clamping device effectively restrains the displacement of goods, especially for goods with unstable centers of gravity or loose packaging, reducing swaying and ensuring stability during handling.

[0040] In use, mounting bracket 1 is installed onto the stacker crane's loading platform using bolts, as follows: Figure 7 As shown, Figure 7 The section marked B is the stacker crane loading platform.

[0041] Furthermore, such as Figures 1-3 As shown, each of the two support bases 101 is connected to a first connecting shaft 102, and the outer surface of the first connecting shaft 102 is connected to the first L-shaped plate 103. The first L-shaped plate 103 is fixedly connected to the first connecting shaft 102. A bearing is provided at the connection between the first connecting shaft 102 and the support base 101. The first L-shaped plate 103 can be supported by the cooperation between the support base 101 and the first connecting shaft 102.

[0042] Furthermore, such as Figure 2As shown, a second connecting shaft 104 is rotatably connected to the hinge of the first L-shaped plate 103 and the connecting plate 105. A bearing is provided at the connection between the second connecting shaft 104 and the connecting plate 105 or the first L-shaped plate 103. The first L-shaped plate 103 and the connecting plate 105 can be connected together through the second connecting shaft 104.

[0043] Furthermore, such as Figure 2 As shown, a third connecting shaft 110 is rotatably connected to the hinge joint of the linkage rod 106 and the two first L-shaped plates 103. A bearing is provided at the connection between the third connecting shaft 110 and the linkage rod 106 or the first L-shaped plate 103. The first L-shaped plate 103 and the linkage rod 106 can be connected together through the third connecting shaft 110.

[0044] Furthermore, such as Figures 1-3 As shown, the drive unit includes a motor 108 mounted on the mounting frame 1. The output shaft of the motor 108 and the outer surface of one of the first connecting shafts 102 are both provided with transmission wheels 107, and a transmission belt 109 is connected between the two transmission wheels 107. The motor 108 can drive the corresponding first connecting shaft 102 to rotate through the cooperation of the transmission wheels 107 and the transmission belt 109, thereby enabling the clamping plate 2 to move closer to or away from the mounting frame 1. When the clamping plate 2 moves away from the mounting frame 1, it is used to clamp the goods, and when the clamping plate 2 moves closer to the mounting frame 1, it releases the clamping of the goods.

[0045] Furthermore, such as Figure 3 As shown, the clamping assembly includes a clamping plate 2, on which a support frame 4 is mounted. The support frame 4 is bolted to the clamping plate 2. A detection plate 401 is provided on one side of the support frame 4. Several spring telescopic rods 402 are connected between the detection plate 401 and the support frame 4. A detection plate 403 is mounted on the detection plate 401, and a sensor 404 is provided on the support frame 4. During the clamping process, the goods are pressed by the detection plate 401 against the spring telescopic rods 402, causing the detection plate 403 to move towards the mounting frame 1. When the sensor 404 detects the detection plate 403, it indicates that the goods are clamped, and then the motor 108 is stopped. When the goods are released, the detection plate 401 separates from the goods, and the spring telescopic rods 402 drive the detection plate 401 away from the mounting frame 1, causing the detection plate 403 to move away from the sensor 404, indicating that the goods are released in place, and the motor 108 is stopped, thereby realizing the monitoring of the clamping state. The sensor 404 can be a photoelectric sensor, which can be used in conjunction with an existing PLC control system to realize monitoring.

[0046] Example 2 further optimizes the anti-fall-and-grip device for the stacker crane loading platform provided in Example 1. Specifically, as follows: Figures 1-3 As shown, the clamping plate 2 is fixedly connected to one end of the two connecting plates 105.

[0047] Example 3 further optimizes the anti-fall-and-grip device for the stacker crane loading platform provided in Example 1. Specifically, as follows: Figures 4-6 As shown, a connector is provided between the clamping plate 2 and the two connecting plates 105. The connector includes a support plate 5 fixedly connected between the two first L-shaped plates 103. A plurality of connecting rods 501 are inserted and connected on the support plate 5. One end of the connecting rod 501 is fixedly connected to the clamping plate 2. A baffle 502 is fixedly connected to the outer surface of the end of the connecting rod 501 away from the clamping plate 2. The support plate 5 and the clamping plate 2 can be connected together through the connecting rods 501 to support the clamping plate 2.

[0048] A limiting plate 504 is provided on the side of the support plate 5 away from the clamping plate 2. Both the limiting plate 504 and the support plate 5 have an elongated opening 505 and a through opening 506 communicating with the elongated opening 505. The outer surface of the connecting rod 501 passes through the elongated opening 505. The connecting rod 501 can be limited by the cooperation of the limiting plate 504 and the baffle 502.

[0049] Furthermore, such as Figure 4 As shown, a protective sleeve 503 is fitted on the outer surface of the connecting rod 501. The protective sleeve 503 is located between the clamping plate 2 and the support plate 5. The protective sleeve 503 is used to isolate the clamping plate 2 and the support plate 5, so as to leave space between the clamping plate 2 and the support plate 5 to avoid the support frame 4.

[0050] Furthermore, such as Figure 4 and Figure 6 As shown, the top of the limiting plate 504 is threaded with a fastening bolt 507, and the outer surface of the fastening bolt 507 is threadedly connected to one of the connecting plates 105. The fastening bolt 507 can fix the position of the limiting plate 504.

[0051] When replacing clamping plate 2, after unscrewing the fastening bolt 507, pull the limiting plate 504 upward so that the connecting rod 501 reaches the through-hole 506 and the baffle 502 is aligned with the through-hole 506. Pull the clamping plate 2 away from the support plate 5 so that the baffle 502 passes through the through-hole 506 to remove the clamping plate 2. During installation, pass the baffle 502 through the through-hole 506 and push the limiting plate 504 downward so that the connecting rod 501 is inserted into the elongated opening 505. Then, tighten the fastening bolt 507 between the connecting plate 105 and the limiting plate 504 to fix the position of the clamping plate 2 so that it can be replaced if it is damaged.
