Abstract
Description
Technical Field
[0001] This utility model relates to the field of crane technology, specifically to a lifting device. Background Technology
[0002] The hoisting process of the cathode and anode plates in the electrolysis process includes two states: exiting the bipolar plates and installing the bipolar plates. The cathode and anode plates in the electrolytic cell are arranged in an alternating pattern with very small spacing. Due to the limitations of the electrode spacing and the side spacing of the cathode, the cathode must be exited first and then the anode when exiting the bipolar plates, while the anode must be installed first and then the cathode when installing the bipolar plates.
[0003] Taking bipolar electrolysis as an example, after the cathode hook is attached to the cathode plate, the cathode plate is first lifted upwards separately, then the anode hook is attached to the anode plate, and finally the cathode plate and anode plate are lifted together from the electrolytic cell, thus completing the intelligent double lifting of the cathode and anode plates. Existing technology usually uses two lifting devices to lift the cathode and anode plates separately, requiring a complex control system to control the individual lifting of the cathode plate or the synchronous lifting of the cathode and anode plates, which increases the lifting cost. Utility Model Content

[0030] A lifting device includes a trolley 1, a main lifting mechanism 2, and an auxiliary lifting mechanism 3.
[0031] The main hoisting mechanism 2 includes a main winding drum assembly 21, a main winding wire rope 22, a main winding pulley 23, a main winding hook 25, and a main drive assembly. The main winding drum assembly 21 is rotatably mounted on the trolley 1. One end of the main winding wire rope 22 is wound around the main winding drum assembly 21, the main winding wire rope 22 passes over the main winding pulley 23, and the other end of the main winding wire rope 22 is fixed to the trolley 1. The main winding hook 25 is located at the bottom of the main winding pulley 23. The main drive assembly is used to drive the main winding drum assembly 21 to rotate.
[0032] In this embodiment, the main lifting mechanism 2 includes two parallel main winding drum groups 21. Each main winding drum group 21 is connected to two main winding wire ropes 22. Each main winding wire rope 22 is provided with a main winding hook 25. The four main winding hooks 25 are set at the same height, so that the material can be lifted through four lifting points, thereby achieving stable lifting of the first part of the material.
[0033] The main drive assembly includes a main winding motor 26 and a reducer 27. The main winding motor 26 is connected to two main winding drum assemblies 21 via the reducer 27. Thus, the two main winding drum assemblies 21 are driven to rotate synchronously by one main winding motor 26, ensuring the synchronous lifting and lowering of the four main winding hooks 25.
[0034] The auxiliary lifting mechanism 3 includes an auxiliary winding drum assembly 31, an auxiliary winding wire rope 32, an auxiliary winding pulley 33, an auxiliary winding hook 35, and an auxiliary drive assembly. The auxiliary winding drum assembly 31 is rotatably mounted on the trolley 1. One end of the auxiliary winding wire rope 32 is wound around the auxiliary winding drum assembly 31, the auxiliary winding wire rope 32 passes over the auxiliary winding pulley 33, and the other end of the auxiliary winding wire rope 32 is wound around the main winding drum assembly 21. The auxiliary winding hook 35 is located at the bottom of the auxiliary winding pulley 33. The auxiliary drive assembly is used to drive the auxiliary winding drum assembly 31 to rotate.
[0035] In this embodiment, the auxiliary lifting mechanism 3 includes two auxiliary winding drum groups 31 that correspond one-to-one with the two main winding drum groups 21. Each auxiliary winding drum group 31 is connected to the corresponding main winding drum group 21 through two auxiliary winding wire ropes 32. Each auxiliary winding wire rope 32 is equipped with an auxiliary winding hook 35 through an auxiliary winding pulley 33. The four auxiliary winding hooks 35 are set at the same height, so that lifting is achieved through four lifting points, thereby realizing the stable lifting of the second part of the material.
[0036] The auxiliary drive assembly includes two auxiliary winding motors 36, which are respectively connected to two auxiliary winding drum groups 31. The two auxiliary winding motors 36 are kept synchronized by the control system, thereby ensuring the synchronous lifting and lowering of the four auxiliary winding hooks 35.
[0037] In addition, the main hoist hook 25 is connected to the main hoist pulley 23 via the main height adjustment assembly 24, and the auxiliary hoist hook 35 is connected to the auxiliary hoist pulley 33 via the auxiliary height adjustment assembly 34. The main height adjustment assembly 24 allows for the individual adjustment of the height of the four lifting points of the main hoisting mechanism 2, thereby leveling the four lifting points of the main hoisting mechanism 2. Similarly, the auxiliary height adjustment assembly 34 allows for the individual adjustment of the height of the four lifting points of the auxiliary hoisting mechanism 3, thereby leveling the four lifting points of the auxiliary hoisting mechanism 3.
[0038] This embodiment sets up independent main winding drum assembly 21 and auxiliary winding drum assembly 31. When the auxiliary winding drum assembly 31 rotates, the auxiliary winding hook 35 can rise and fall relative to the main winding hook 25. When the main winding drum assembly 21 rotates while the auxiliary winding drum assembly 31 does not rotate, the main winding hook 25 and the auxiliary winding hook 35 can maintain synchronous lifting.
[0039] Therefore, when this embodiment is used for intelligent dual lifting of the cathode and anode plates, the main lifting mechanism 2 can be used to lift the anode plate, and the auxiliary lifting mechanism 3 can be used to lift the cathode plate. When the main winding drum assembly 21 is not rotating while the auxiliary winding drum assembly 31 is rotating, the auxiliary winding hook 35 can be lifted independently, thereby achieving independent lifting of the cathode plate. When the main winding drum assembly 21 is rotating while the auxiliary winding drum assembly 31 is not rotating, the main winding hook 25 and the auxiliary winding hook 35 can be lifted synchronously, realizing the lifting of the cathode and anode plates together from the electrolytic cell.
[0040] Furthermore, the axes of the main roll assembly 21 and the auxiliary roll assembly 31 are parallel, and the auxiliary roll assembly 31 includes an auxiliary roll shaft 311 and an auxiliary roll 312, with the auxiliary roll 312 mounted parallel and eccentrically on the auxiliary roll shaft 311. A secondary drive assembly is used to drive the auxiliary roll assembly 31 to rotate about the axis of the auxiliary roll shaft 311.
[0041] In this embodiment, by eccentrically setting the auxiliary winding drum 312 on the auxiliary winding drum assembly 31, when the auxiliary winding drum assembly 31 rotates at a certain angle, the auxiliary winding hook 35 can achieve a relative displacement in the horizontal direction relative to the main winding hook 25. When hoisting the cathode plate and anode plate, the cathode plate can be offset by a certain distance, leaving sufficient space between the cathode plate and anode plate to facilitate the hooking and hoisting of the anode plate.
[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
