Abstract
Description
Technical Field
[0001] This utility model relates to the field of horizontal smelting furnace technology, specifically a lifting device for dismantling a horizontal smelting furnace. Background Technology
[0002] A horizontal smelting furnace typically consists of a furnace body, furnace cover, electrodes (for electric furnaces), heat exchange system, and control system. The interior of the furnace body is lined with refractory material to withstand the high temperatures and the erosion of the molten metal.
[0003] The working principle of horizontal smelting furnaces varies depending on the type. Taking a horizontal electric smelting furnace as an example, its working principle mainly utilizes the conversion of electrical energy into heat energy. Current is introduced into the furnace charge through electrodes, causing the charge to rapidly heat up and melt under the influence of a strong current. Simultaneously, the atmosphere and temperature inside the furnace can be precisely controlled to meet the smelting requirements of different metals. When existing horizontal smelting furnaces need to be completely dismantled, a lifting device is required to safely raise the furnace body. Current lifting methods all rely on conventional equipment such as hydraulic rods or jacks, which cannot move the dismantled horizontal smelting furnace during dismantling. To solve the above problems, a lifting device for the dismantling of horizontal smelting furnaces is proposed. Summary of the Invention
[0004] The purpose of this invention is to solve the above-mentioned problems and provide a lifting device for dismantling horizontal smelting furnaces.
[0005] The specific solution of this utility model is as follows: a lifting device for dismantling a horizontal smelting furnace, comprising a trolley, a lifting assembly connected to the surface of the trolley, the lifting assembly including a connecting rod, a first gear connected to both sides of the connecting rod, a motor connected to the front surface of the trolley, a second gear meshing with the output end of the motor, support frames connected to both sides of the trolley, a sleeve connected inside the support frame, a one-way screw connected inside the sleeve, a third gear connected to the bottom of the one-way screw, a lifting plate connected to the surface of the one-way screw, a threaded hole opened inside the lifting plate, and a top lifting plate connected to the top of the lifting plate.
[0006] Preferably, lifting sleeves are connected to the four bottom corners of the lifting plate, and connecting columns are connected to the four corners of the surface of the trolley. The connecting columns and lifting sleeves can improve the stability of the lifting plate when it is raised or lowered.
[0007] Preferably, the surface of the lifting plate is connected with an anti-slip pad, and the third gear meshes with the first gear, so that the two sets of one-way screws can be driven to rotate simultaneously through meshing.
[0008] Preferably, the one-way screw is connected to the lifting plate through a threaded hole, which facilitates the lifting of the lifting plate and thus the lifting of the jacking plate.
[0009] Preferably, the trolley is equipped with anti-slip components at the four corners near the casters. The anti-slip components include threaded grooves, and threaded rods are connected inside the threaded grooves. The horizontal smelting furnace can be fixed after being lifted by the anti-slip components.
[0010] Preferably, a handle is connected to the top of the threaded rod, and a suction cup is connected to the bottom of the threaded rod. The rotation of the threaded rod can cause the suction cup to adhere to the ground to prevent slippage.
[0011] This utility model has the following beneficial effects:
[0012] 1. In this utility model, when dismantling and lifting a horizontal smelting furnace, two sets of devices can be placed at the bottom of both sides of the horizontal smelting furnace. Then, the horizontal smelting furnace can be lifted and dismantled by the lifting plate. Finally, the horizontal smelting furnace can be moved by the universal wheels at the bottom of the trolley, which improves the convenience of moving the horizontal smelting furnace after dismantling.

If the specific posture changes, the directional indicators will also change accordingly.
[0022] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0023] Please see Figures 1-4This utility model provides a technical solution: a lifting device for dismantling a horizontal smelting furnace, including a trolley 1, a lifting assembly 2 connected to the surface of the trolley 1, the lifting assembly 2 including a connecting rod 201, a first gear 202 connected to both sides of the connecting rod 201, a motor 203 connected to the front surface of the trolley 1, a second gear 204 meshing with the output end of the motor 203, a support frame 205 connected to both sides of the trolley 1, a sleeve 206 connected inside the support frame 205, a one-way screw 207 connected inside the sleeve 206, a third gear 208 connected to the bottom of the one-way screw 207, a lifting plate 209 connected to the surface of the one-way screw 207, a threaded hole 210 opened inside the lifting plate 209, and a lifting plate 211 connected to the top of the lifting plate 209.
[0024] like Figure 2 and Figure 3 As shown, lifting sleeves 212 are connected to the four corners of the bottom of the lifting plate 211, and connecting columns 213 are connected to the four corners of the surface of the trolley 1. The connecting columns 213 and the lifting sleeves 212 can improve the stability of the lifting plate 211 when it is raised or lowered.
[0025] like Figure 3 and Figure 4 As shown, the surface of the lifting plate 211 is connected with an anti-slip pad 214, and the third gear 208 meshes with the first gear 202. Through meshing, the two sets of one-way screws 207 can be driven to rotate simultaneously.
[0026] like Figure 3 and Figure 4 As shown, the one-way screw 207 is connected to the lifting plate 209 through the threaded hole 210. The threaded connection allows for easy lifting of the lifting plate 209, thereby lifting the lifting plate 211.
[0027] like Figure 5 As shown, anti-slip components 3 are provided at the four corners of the trolley 1 near the casters. The anti-slip components 3 include threaded grooves 301, and threaded rods 302 are connected inside the threaded grooves 301. The horizontal smelting furnace after being lifted can be fixed by the anti-slip components 3.
[0028] like Figure 1 and Figure 4 As shown, a handle 303 is connected to the top of the threaded rod 302, and a suction cup 304 is connected to the bottom of the threaded rod 302. The rotation of the threaded rod 302 can cause the suction cup 304 to adhere to the ground to prevent slippage.
[0029] The usage and working principle of this device are as follows: When dismantling the horizontal smelting furnace, the two sets of trolleys 1 can be pushed to the bottom of both sides of the horizontal smelting furnace. Then, the reverse function of the motor 203 can be activated to drive the second gear 204 to reverse. At the same time, the second gear 204 reverses, which also drives the two sets of first gears 202 to reverse through the connecting rod 201. While the first gears 202 are rotating in the opposite direction, they also mesh with the third gear 208 in the opposite direction, thereby simultaneously driving the two sets of one-way screws 207 to reverse. The support frame 205 fixes the sleeve 206, and the sleeve 206 can improve the stability of the one-way screws 207 when rotating. When the two sets of one-way screws 207 rotate in the opposite direction with the lifting plate 209 through the threaded hole 210, they will simultaneously drive the two sets of lifting plates 209 to move upward. When the lifting plate 209 moves upward, it will lift the horizontal smelting furnace through the lifting plate 211, thereby lifting and dismantling the horizontal smelting furnace. Then, the horizontal smelting furnace can be moved to the designated area by the universal wheels at the bottom of the trolley 1. When it is necessary to put the horizontal smelting furnace on the ground, the forward rotation function of the motor 203 can be started to drive the two sets of one-way screws 207 to rotate forward, so that the lifting plate 209 can drive the lifting plate 211 to move downward. The lifting sleeve 212 and the connecting column 213 can improve the stability of the lifting plate 211 during lifting. When the trolley 1 is not in use, the handle 303 can be turned to drive the threaded rod 302 and the threaded groove 301 to rotate, thereby causing the suction cup 304 to move downward and be attached to the ground, which improves the safety of the trolley 1 during use.
