Description

Technical Field

[0001] This utility model relates to the technical field of lifting platforms, specifically an automatic blocking mechanism for a conveyor line. Background Technology

[0002] During the transportation of goods within the factory area, it is necessary to lift the goods to a certain height to meet the height requirements of the next workstation for processing, sorting, packaging, etc. A common way to lift goods on site is to use a lifting platform.

[0003] A common type of lifting platform includes a lifting plate, a hydraulic cylinder, a mounting frame, and a scissor frame. The lifting plate is mounted on the scissor frame, which is mounted on the mounting frame. The hydraulic cylinder is mounted on the mounting frame, and its telescopic shaft is connected to the scissor frame. Driving the hydraulic cylinder causes the scissor frame to retract or expand, thereby raising or lowering the lifting plate. To facilitate the movement of goods, guide wheels are usually installed on the lifting plate to reduce friction between the goods and the lifting plate when pushing them, thus facilitating the movement of goods.

[0004] Regarding the aforementioned technical conditions, there are also some defects in the installation of lifting platforms that are tilted. When the lifting platform is raised or lowered, the goods move on the lifting platform due to shaking. When the shaking is too large, the goods are prone to falling off the lifting platform.

[0005] Based on this, the present invention designs an automatic blocking mechanism for a conveyor line to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic blocking mechanism for a conveyor line, comprising a mounting frame, a lifting plate mounted on the mounting frame, and a scissor frame for supporting the lifting plate. Goods are placed on the lifting plate. A fixed plate is fixedly mounted on the ground near the mounting frame. A guide block, which is a wedge-shaped block, is fixedly connected to the fixed plate. The mounting plate is fixedly mounted on the lifting plate. A connecting plate is rotatably mounted on the mounting plate. A rotating rod is rotatably connected to the connecting plate. A telescopic spring is fixedly connected to one end of the rotating rod. The spring is fixedly connected to the mounting plate. A lifting groove is formed on the lifting plate. A baffle is inserted into the lifting groove. A connecting rod is rotatably mounted on the mounting plate. The baffle is fixedly connected to the connecting rod. A placement plate is rotatably mounted on the rotating rod. The placement plate is rotatably connected to the connecting rod. When the lifting plate moves to its lowest position, the guide block abuts against the connecting plate. Simultaneously, the rotating rod drives the placement plate to rotate upward, which in turn drives the connecting rod to rotate upward, causing the baffle to retract into the lifting groove.

[0007] By adopting the above technical solution, when the lifting platform descends to its lowest position, the connecting plate abuts against the guide block, causing the connecting rod to rotate upward and the stop block to retract into the lifting groove, thus removing the obstruction to the goods and facilitating the entry and exit of the goods. When the connecting plate no longer abuts against the guide block, the connecting rod rebounds under the pull of the telescopic spring. At this time, the stop block is located outside the lifting groove, blocking the goods. This achieves the effect of automatically blocking the goods when the lifting platform rises, preventing the goods from sliding off the lifting platform.

[0008] Preferably, the connecting plate is rotatably provided with guide wheels.

[0009] By adopting the above technical solution, the guide wheel contacts the guide block, reducing friction and making the connecting plate rotate more smoothly.

[0010] Preferably, two baffles are provided on the lifting plate.

[0011] By adopting the above technical solution, the two baffles can simultaneously block the goods, further improving the protection area.

[0012] Preferably, the lifting device is fixedly equipped with a protective plate, and there are two protective plates, with the goods located between the two protective plates.

[0013] By adopting the above technical solution, the protective plate blocks one or both sides of the cargo, further reducing the risk of the cargo falling off the lifting platform.

[0014] Preferably, a mounting base is fixedly provided on the mounting plate, an adjusting rod is threadedly connected to the mounting base, and one end of the telescopic spring is fixedly connected to the adjusting rod.

[0015] By adopting the above technical solution, the tension of the telescopic spring can be adjusted by rotating the adjusting rod, thus ensuring that the connecting rod returns to its original position immediately.

[0016] In summary, this application has the following beneficial technical effects: When the lifting plate descends to its lowest position, the connecting plate abuts against the guide block, causing the connecting rod to rotate upward and the stop block to retract into the lifting groove, thus eliminating the obstruction of goods and facilitating the entry and exit of goods. When the connecting plate no longer abuts against the guide block, the connecting rod rebounds under the pull of the telescopic spring, and the stop block is located outside the lifting groove, blocking the goods. This achieves the effect of automatically blocking the goods when the lifting plate rises, preventing the goods from sliding off the lifting plate. Attached Figure Description

[0025] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] Reference Figures 1-5 An automatic blocking mechanism for a conveyor line includes a mounting frame 1, a lifting plate 2 mounted on the mounting frame 1, and a scissor frame 3 for supporting the lifting plate 2. Goods are placed on the lifting plate 2. A fixed plate 4 is fixedly mounted on the ground near the mounting frame 1. A guide block 5, which is a wedge-shaped block, is fixedly connected to the fixed plate 4. A mounting plate 6 is fixedly mounted on the lifting plate 2. A connecting plate 7 is rotatably mounted on the mounting plate 6. A guide wheel 8 is fixedly mounted on the connecting plate 7. A rotating rod 9 is rotatably connected to the connecting plate 7. A mounting base 10 is fixedly mounted on the mounting plate 6. An adjusting rod 11 is threadedly connected to the mounting base 10. A telescopic spring 12 is fixedly connected to the adjusting rod 11. One end of the telescopic spring 12 is fixedly connected to the rotating rod 9, and the telescopic spring 12 pulls the rotating rod 9.

[0028] Reference Figures 1-5 The lifting plate 2 has a lifting groove 14, and a baffle 15 is inserted into the lifting groove 14. A connecting rod 16 is rotatably mounted on the mounting plate 6. The baffle 15 is fixedly connected to the connecting rod 16. A placement plate 17 is rotatably mounted on the mounting plate 6 and is rotatably connected to the connecting rod 16. There are two baffles 15 on the infeed side of the lifting plate 2 and two baffles 15 on the outfeed side.

[0029] Reference Figures 1-5 As the lifting plate 2 moves downward, the guide block 5 contacts the guide wheel 8. As it continues to move downward, the guide block 5 rotates against the guide wheel 8, causing the connecting plate 7 to rotate. This causes the rotating rod 9 to rotate upward, stretching the telescopic spring 12. At the same time, the placement plate 17 moves upward, causing the end of the connecting rod 16 away from the baffle 15 to move upward, while the end of the connecting rod 16 with the baffle 15 moves downward. When the lifting plate 2 is at its lowest position, the baffle 15 is completely located in the lifting groove 14, removing the obstruction to the goods and allowing the goods on the lifting plate 2 to enter and exit.

[0030] Reference Figures 1-5 When the lifting plate 2 rises, the guide wheel 8 moves along the guide block 5. At the same time, the telescopic spring 12 pulls the rotating rod 9 to reset and move downward. The placement plate 17 moves downward, causing the end of the connecting rod 16 away from the baffle 15 to move downward. The end of the connecting rod 16 with the baffle 15 is tilted upward, allowing the baffle 15 to move outward toward the lifting groove 14. When the guide wheel 8 completely disengages from the guide block 5, the baffle 15 is completely outside the lifting groove 14, blocking the goods being transported in the lifting process, thus automatically preventing the goods from sliding out in the infeed or outfeed direction.

[0031] Reference Figures 1-5 The guide wheel 8 contacts the guide block 5, reducing friction and making the connecting plate 7 rotate more smoothly; the two baffles 15 simultaneously block the goods, further improving the protection area.

[0032] Reference Figures 1-5 The lifting platform is fixedly equipped with two protective plates 13. The goods are positioned between the two protective plates 13. The protective plates 13 are located on both sides of the lifting platform 2 where the goods are not being moved in or out, thus blocking the goods from both sides and further reducing the distance between the goods and the lifting platform 2. According to actual needs, the adjusting rod 11 is rotated to adjust the tension of the telescopic spring 12, ensuring that the connecting rod 16 returns to its original position immediately.

[0033] The implementation principle of this embodiment is as follows: when the goods are lifted and transported on the lifting plate 2, the protective plate 13 also blocks the goods from entering, and at the same time, the baffle 15 is located outside the lifting groove 14, blocking the two directions of entering and exiting the goods, so as to prevent the goods from sliding out from the direction of entering or exiting the goods.
