[0003] During feeding, the feed inlet of the overhead crane hopper must be aligned with the discharge outlet of the fixed bell valve.

Positioning of the overhead crane is achieved when the scale on the overhead crane aligns with the scale on the first guide rail. The overhead crane trolley and the second guide rail are equipped with a photoelectric switch transmitter and receiver.

The overhead crane trolley moves the overhead crane hopper horizontally to the lower outlet of the dustproof bag to connect with the feeding port. With prolonged use, this method can easily lead to mutual wear between the feed inlet of the overhead crane hopper and the lower outlet of the dustproof bag, reducing the tightness of the connection at the feeding port and causing material to fly away. Therefore, improving the sealing at the feeding port connection is an important problem that needs to be solved. Utility Model Content

Detailed Implementation
[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] The purpose of this invention is to provide a crane feeding alignment device and crane feeding equipment to solve the problems existing in the prior art, improve the sealing effect at the feeding joint, and reduce material flying.
[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] Example 1 This embodiment provides a crane feeding and alignment device, such as Figure 1 As shown, it includes a telescopic docking device; the telescopic docking device includes a telescopic mechanism and a telescopic tube 20; the upper opening of the telescopic tube 20 is used to communicate with the lower opening of the unloading bell valve 10 (the unloading bell valve 10 is located below the factory roof 40); a docking ring plate 22 is fixed to the lower opening of the telescopic tube 20 (a maintenance platform 41 is provided at the position corresponding to the lower end of the telescopic tube 20, and a through hole is provided on the maintenance platform 41, through which the docking ring plate 22 at the lower end of the telescopic tube 20 can pass and be located below it); the telescopic mechanism is used to be installed on the fixing plate 14 at the lower opening of the unloading bell valve 10, the telescopic end of the telescopic mechanism is connected to the docking ring plate 22, and the telescopic end of the telescopic mechanism can drive the docking ring plate 22 to extend and retract in the vertical direction.
[0023] By setting up a telescopic docking device, the telescopic mechanism installed on the fixed plate 14 at the lower opening of the discharge bell valve 10 drives the docking ring plate 22 at the lower end of the telescopic tube 20 to extend and retract vertically. After the crane hopper 31 is horizontally positioned, the telescopic mechanism drives the docking ring plate 22 to extend downward, so that the lower end of the telescopic tube 20 and the feed inlet of the crane hopper 31 can achieve a flexible and tight fit in the vertical direction, replacing the original rigid horizontal docking of the fixed dustproof bag. This effectively reduces mutual wear at the docking point, significantly improves the sealing fit of the feed port, and fundamentally solves the problem of material flying. At the same time, the vertical telescopic adjustment capability of the telescopic mechanism can adapt to the slight horizontal alignment deviation of the feed inlet of the crane hopper 31, enhancing the flexibility and reliability of the alignment docking and reducing equipment maintenance costs.
[0024] Other relevant settings for the telescopic docking device include: Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1As shown, the telescopic tube 20 is a corrugated pipe. The corrugated pipe itself has excellent extensibility and flexibility, which can perfectly adapt to the vertical telescopic movement of the docking ring plate 22 driven by the telescopic mechanism. At the same time, it can buffer the impact force between the docking ring plate 22 and the feed port of the crane hopper 31 during the docking process, and can always maintain the pipe body in a sealed state during the telescopic process, effectively preventing material leakage from the telescopic tube 20 body, and further improving the sealing reliability of the entire crane feeding and alignment device.
[0025] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 As shown, the telescopic mechanism includes two telescopic hydraulic cylinders 21, which are located on opposite sides of the telescopic tube 20. The upper end of the telescopic hydraulic cylinder 21 is connected to the fixing plate 14 at the lower opening of the unloading bell valve 10, and the lower end of the telescopic hydraulic cylinder 21 is connected to the docking ring plate 22. The symmetrical layout ensures that the docking ring plate 22 is subjected to uniform force when the telescopic hydraulic cylinder 21 drives the docking ring plate 22 to extend and retract, preventing the docking ring plate 22 from tilting or shifting, and ensuring the accuracy of docking between the lower opening of the telescopic tube 20 and the feed inlet of the overhead crane hopper 31. At the same time, the telescopic hydraulic cylinder 21 has strong driving force and stable output, which can adapt to the docking pressure requirements under different working conditions, significantly improving the stability of the docking process and the final sealing effect.
[0026] In the optional solutions of this embodiment, a more preferred embodiment is that a flexible sealing ring is fixedly provided on the lower end face of the docking ring plate 22. When the telescopic mechanism drives the docking ring plate 22 downward to contact the feed inlet of the overhead crane hopper 31, the flexible sealing ring can fill the tiny gap between the docking surfaces of the docking ring plate 22 and the feed inlet of the overhead crane hopper 31 through its own deformation, significantly enhancing the sealing performance at the docking point; at the same time, the flexible material can reduce the rigid collision during docking, reduce the wear of the docking ring plate 22 and the feed inlet of the overhead crane hopper 31, and extend the service life of the equipment.
[0027] Specifically, the sealing ring can be made of common materials such as rubber.
[0028] The following are the specifications regarding the overhead crane mechanism that works in conjunction with the telescopic docking device: Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1As shown, it also includes a crane mechanism; the crane mechanism includes a crane trolley 30, a crane trolley 32, a first guide rail, and a second guide rail; the first guide rail is fixed in position, and the crane trolley 32 travels along a first direction on the first guide rail; the second guide rail is fixedly mounted on the crane trolley 32; the crane trolley 30 travels along a second direction on the second guide rail; the first direction and the second direction are perpendicular to each other and both perpendicular to the vertical direction; a crane hopper 31 is fixedly mounted on the crane trolley 30, and the feed inlet of the crane hopper 31 is used to connect with the lower opening of the telescopic pipe 20. With the first guide rail fixed in position, the crane trolley 32 traveling along the first direction, the second guide rail fixed on the crane trolley 32, and the crane trolley 30 traveling along a second direction perpendicular to the first direction, this structure provides a precise horizontal positioning basis for the telescopic docking device, ensuring the smooth vertical docking of the subsequent telescopic docking device with the feed inlet of the crane hopper 31, and guaranteeing the continuity and coordination of the feeding process.
[0029] In the optional embodiments of this example, a preferred embodiment includes a first position sensor on the overhead crane trolley 32. This first position sensor measures the relative position of the overhead crane trolley 32 on the first guide rail, and the drive controller of the overhead crane trolley 32 is communicatively connected to both the first position sensor and the brake of the overhead crane trolley 32. A second position sensor is installed on the overhead crane trolley 30. This second position sensor measures the relative position of the overhead crane trolley 30 on the second guide rail, and the drive controller of the overhead crane trolley 30 is communicatively connected to both the second position sensor and the brake of the overhead crane trolley 30. This configuration enables automatic detection and closed-loop control of the positions of the overhead crane trolley 32 and the overhead crane trolley 30. Compared to the original manual operation controller and simple photoelectric switch positioning, this significantly improves the accuracy and response speed of the overhead crane's horizontal positioning, reduces positioning errors, and provides the prerequisite for precise docking of the telescopic docking device with the feed inlet of the overhead crane hopper 31, thereby reducing docking wear and the risk of material scattering.
[0030] In the optional solutions of this embodiment, a preferred embodiment is a radar position sensor. The transmitting end of the radar position sensor is set on the overhead crane 32 and the receiving end of the radar position sensor is set on the first guide rail, or the transmitting end of the radar position sensor is set on the first guide rail and the receiving end of the radar position sensor is set on the overhead crane 32. The first position sensor is a radar position sensor, which has the characteristics of high measurement accuracy and strong anti-interference ability. It is not affected by adverse factors such as dust and light in the electrolysis production environment, and can stably and accurately detect the position of the overhead crane 32 on the first guide rail. Moreover, the transmitting end and the receiving end of the radar position sensor can be flexibly set at different positions of the overhead crane 32 and the first guide rail to adapt to different installation scenarios, ensure the reliability of the positioning data of the overhead crane 32, and improve the adaptability and positioning stability of the overhead crane feeding and positioning device under complex working conditions.
[0031] In the optional solutions of this embodiment, a preferred option is that the second position sensor is a radar position sensor. The second position sensor, being a radar position sensor, has the advantages of high precision and strong anti-interference capabilities. It can accurately measure the position of the overhead crane trolley 30 on the second guide rail in the harsh environment of the electrolysis workshop, where there is a lot of dust and electromagnetic interference, avoiding positioning deviations caused by environmental interference. Working in conjunction with the radar position sensor of the overhead crane trolley 32, it jointly improves the overall horizontal positioning accuracy of the overhead crane, providing a solid guarantee for the sealed docking of the telescopic docking device with the feed inlet of the overhead crane hopper 31.
[0032] Specifically, the configuration of the receiver and transmitter of the second position sensor is the same as that of the first position sensor, and will not be elaborated further here.
[0033] Example 2 This embodiment provides a crane feeding device, including a feeding bell valve 10 and a crane feeding alignment device as described in Embodiment 1. The feeding bell valve 10 has a feeding plug 11 that can block the lower opening of the feeding bell valve 10. The feeding plug 11 is fixedly mounted on the telescopic drive rod 12. The feeding bell valve 10 includes an actuator 13 (the feeding bell valve 10 is an existing device and will not be described in detail here. Its principle is that the actuator 13 is used to control the extension and retraction of the telescopic drive rod 12, thereby achieving the blocking and opening of the lower opening of the feeding plug 11). The actuator 13 is used to drive the telescopic drive rod 12 to extend and retract to achieve the blocking of the lower opening of the feeding bell valve 10 by the feeding plug 11. The telescopic docking device is mounted on the fixing plate 14 at the lower opening of the feeding bell valve 10.
[0034] With the cooperation of the discharge bell valve 10 and the telescopic docking device, when feeding, the actuator 13 drives the telescopic drive rod 12 to retract and open the discharge plug 11, and the telescopic docking device achieves a sealed docking with the feed inlet of the overhead crane hopper 31; after feeding is completed, the actuator 13 drives the telescopic drive rod 12 to extend so that the discharge plug 11 seals the lower opening of the discharge bell valve 10, providing double protection against material leakage and greatly improving the operational sealing and reliability of the entire overhead crane feeding equipment.
[0035] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
