Description

Technical Field

[0001] This utility model relates to the field of unloading technology, specifically a self-unloading lifting device for metal materials. Background Technology

[0002] In industries such as metallurgy, building materials, ports, power, and warehousing and logistics, self-unloading cranes for metal materials are widely used for lifting and unloading bulk materials (such as metals, ores, coal, sand, gravel, and cement). These cranes typically include a hoisting mechanism, a boom, a hook, and a hopper or self-unloading device connected to the hook. Their working principle involves lifting a hopper filled with material to the target position via the hoisting mechanism, and then automatically unloading the material using gravity or mechanical tilting.

[0003] However, in existing technologies, some self-unloading lifting devices for metal materials often directly perform a lifting operation after completing the unloading action, meaning they begin to rise and return to their original position before the hopper is completely empty. This operation method has significant drawbacks: due to the hopper's structural design or limitations in material flowability, some material may remain at the bottom or in corners of the hopper and cannot be completely discharged during the brief dumping process. When the lifting device is lifted, the remaining material remains in the hopper due to inertia or adhesion, not only causing material waste but also potentially leading to inaccurate weighing and measurement, cross-contamination, or abnormal equipment load problems.

[0004] Therefore, it is necessary to provide a self-unloading lifting device for metal materials to solve the above problems. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the purpose of this utility model is to provide a self-unloading lifting device for metal materials to solve the problems mentioned in the background technology.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a self-unloading hoist for metal materials, including a hopper and a bin. The top long side of the hopper has an elastic telescopic docking platform for supporting the hopper. The bin has a body, a slider, a baffle and a connecting rod. The baffle is located at the bottom of the bin. One end of the connecting rod is hinged to the slider and the other end is hinged to the baffle. The slider drives the baffle to open and close through the connecting rod. A hydraulic cylinder is provided between the two connecting rods on the same slider.

[0007] Furthermore, the hopper also has a bearing platform on both sides, and the bearing platform has a spring inside. One end of the spring abuts against the bottom of the bearing platform cavity, and the other end abuts against the bottom of the docking platform.

[0008] Furthermore, the connecting rod includes a front connecting rod and a rear connecting rod, the baffle includes a front baffle and a rear baffle, the long side of the front baffle is hinged to the long side of the bucket body, the other long side of the front baffle is hinged to the front connecting rod, and one end of the front connecting rod is hinged to the slider. The long side of the rear baffle is hinged to the long side of the bucket body, the other long side of the rear baffle is hinged to the rear connecting rod, and one end of the rear connecting rod is hinged to the slider. The hydraulic cylinder has a cylinder barrel and a piston rod, the cylinder barrel being hinged to a front connecting rod and the piston rod being hinged to a rear connecting rod.

[0009] Furthermore, tracks are fixedly connected to the two short outer walls of the bucket body, and the slider slides up and down along the tracks.

[0010] Furthermore, the hopper also includes a lifting beam, with support arms extending downward from both ends of the lifting beam, and the end of the support arm away from the lifting beam being fixedly connected to the slider.

[0011] Furthermore, several legs are fixedly connected to the outer wall of the long side of the bucket body.

[0012] The beneficial effects of this utility model are as follows: The self-unloading hoist for metal materials provided by this utility model has a hydraulic cylinder installed on the connecting rod of the control baffle, and an elastic telescopic docking platform installed on the hopper. When the hopper is unloading, the docking platform and the hydraulic cylinder jointly bear the weight of the hopper, so that the lifting beam can lift and lower the hopper back and forth, causing the hopper to shake and shake out the dead corner material and residual material into the hopper. This avoids the situation where some material is stuck at the bottom or corner of the hopper and cannot be completely discharged during the short dumping process.

[0015] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] 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.

[0017] like Figure 1-6 As shown, the present invention provides a technical solution: a self-unloading hoist for metal materials, including a hopper 1 and a bin 2. The top long side of the hopper 1 has an elastic telescopic docking platform 12 for supporting the hopper 1. The bin 2 has a bin body 21, a slider 23, a baffle and a connecting rod. The baffle is located at the bottom of the bin body 21. One end of the connecting rod is hinged to the slider 23 and the other end is hinged to the baffle. The slider 23 drives the baffle to open and close through the connecting rod. A hydraulic cylinder 28 is provided between the two connecting rods on the same slider 23.

[0018] The hopper 1 also has a bearing platform 11 on both sides. The bearing platform 11 has a spring 13 inside. One end of the spring 13 abuts against the bottom of the cavity of the bearing platform 11, and the other end abuts against the bottom of the docking platform 12.

[0019] The connecting rod includes a front connecting rod 24 and a rear connecting rod 25, and the baffle includes a front baffle 26 and a rear baffle 27. The long side of the front baffle 26 is hinged to the long side of the bucket body 21, and the other long side of the front baffle 26 is hinged to the front connecting rod 24. One end of the front connecting rod 24 is hinged to the slider 23. The long side of the rear baffle 27 is hinged to the long side of the bucket body 21, and the other long side of the rear baffle 27 is hinged to the rear connecting rod 25. One end of the rear connecting rod 25 is hinged to the slider 23. The hydraulic cylinder 28 has a cylinder barrel 281 and a piston rod 282. The cylinder barrel 281 is hinged to the front connecting rod 24, and the piston rod 282 is hinged to the rear connecting rod 25.

[0020] Tracks 211 are fixedly connected to the two short outer walls of the bucket body 21, and the slider 23 slides up and down along the tracks 211.

[0021] The hopper 2 also includes a lifting beam 22, with support arms 221 extending downward from both ends of the lifting beam 22. The end of the support arm 221 away from the lifting beam 22 is fixedly connected to the slider 23.

[0022] Several legs 29 are fixedly connected to the outer wall of the long side of the bucket body 21.

[0023] In one embodiment, the crane operates as follows:

[0024] Specifically, after the material is filled into the hopper 2, the crane lifts the lifting beam 22 and moves the hopper 2 to the top of the silo 1. After the position of the support leg 29 is aligned with the docking platform 12, the crane controls the lifting beam 22 to move downward. At this time, the docking platform 12 is subjected to the pressure of the weight of the hopper 2 and gradually moves downward. The spring 13 is compressed to generate elastic force. As the lifting beam 22 continues to descend, the outrigger 221 also descends, and the outrigger 29 lands on the bearing platform 11. When the slider 23 descends along the track 211, the connecting rod causes the baffle to unfold around the long side of the bucket body 21, so that the bottom of the bucket body 21 is connected to the opening of the hopper 1. The material in the bucket 2 falls into the hopper 1. When the slider 23 is at the lower limit position, the baffle is fully unfolded. At this time, the hydraulic cylinder 28 is also fully opened, and the piston rod 282 extends outward to the limit position of the cylinder 281. After the material is discharged, the crane is controlled to lift the lifting beam 22 upward. At this time, the spring force of the spring 13 is released, and the hydraulic cylinder 28 opens the front baffle 26 and the rear baffle 27. The lifting beam 22 can lift the hopper 2. The crane is controlled to rise and fall repeatedly. The baffle is kept open under the action of the hydraulic cylinder 28. At the same time, the docking platform 12 can also bear part of the force of the hopper 2. At this time, the hopper 2 shakes up and down, shaking out the material remaining in the hopper 21. After shaking until no residual material comes out, the lifting beam 22 continues to rise, and the slider 23 also rises. Then, under the action of the connecting rod, the baffle is pulled closer to the bottom of the bucket 21, so that the bottom of the bucket 21 is closed. At this time, the support leg 29 also disengages from the docking platform 12. Since there is no support from the docking platform 12, the lifting beam 22 bears the weight of the entire bucket 21. When the hydraulic cylinder 28 cannot bear the weight, the piston rod 282 retracts into the cylinder 281. The two connecting rods also gradually approach each other until the slider 23 is at the upper limit position of the bucket 2. Then the hydraulic cylinder 28 retracts to the minimum stroke. With the movement of the crane, the bucket 2 continues to be filled with material.

[0025] In summary, this self-unloading lifting device has a hydraulic cylinder 28 installed on the connecting rod that controls the opening and closing of the baffle, and an elastic telescopic docking platform 12 installed on the hopper 1. When the hopper 2 is unloading, the docking platform 12 and the hydraulic cylinder 28 jointly bear the weight of the hopper 2, so that the lifting beam 22 can lift and lower the hopper 2 repeatedly, causing the hopper body 21 to shake and shake out the dead corner material and residual material into the hopper 1. This avoids the situation where some material is stuck at the bottom or corner of the hopper 2 and cannot be completely discharged during the short dumping process.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
