Description

Technical Field

[0001] This utility model relates to the field of metallurgy, and in particular to a hydraulic lifting device for the smelting industry. Background Technology

[0002] In hydrometallurgical industrial production, electrolytic extraction is commonly used to extract pure metals such as gold, silver, copper, zinc, nickel, and cobalt from solutions. In practice, electrolysis deposits the target metal onto the exposed surface of the cathode plate in the electrolytic cell. When the deposited metal layer reaches a certain thickness, a lifting device is used to lift the cathode plate out of the electrolytic cell. Then, the metal layer deposited on the cathode plate is peeled off from the cathode plate itself. Finally, the cathode plate is lifted back into the electrolytic cell using the lifting device to continue electrolysis, thus recycling the process.

[0003] In existing technologies, lifting devices generally use a motor-driven worm gear mechanism to drive the lifting mechanism, thereby enabling the lifting and lowering of cathode plates. Although the worm gear mechanism has a self-locking function, it is inefficient. During continuous lifting and lowering, the copper sleeve inside the worm gear mechanism is easily worn, resulting in a short overall lifespan for the entire lifting device. Smelters need to frequently repair and replace the worm gear mechanism, leading to high time and cost. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a hydraulic lifting device for the smelting industry, so as to solve the above-mentioned problem.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A hydraulic lifting device for the smelting industry includes: a power mechanism, a hydraulic cylinder, a scissor lift mechanism, two cathode plate hanging mechanisms, a mounting frame, two active drive mechanisms, two driven drive mechanisms, and two anti-deviation mechanisms; the two cathode plate hanging mechanisms are arranged side by side below the scissor lift mechanism and are detachably connected to multiple cathode plates; the scissor lift mechanism is mounted on the mounting frame and connected to the hydraulic cylinder; the power mechanism is mounted on the mounting frame and connected to the hydraulic cylinder; the active drive mechanism... The mechanism and the driven mechanism are respectively disposed at both ends of the mounting frame and are slidably connected to the displacement track. The two anti-deviation mechanisms are installed one-to-one on the two driven mechanisms and are slidably connected to the displacement track. The power mechanism includes a power motor, a gear pump, a hydraulic oil tank and a solenoid valve. The power motor is connected to the gear pump, the hydraulic oil tank is connected to the hydraulic cylinder, and the solenoid valve is disposed on the hydraulic oil tank. When the output pressure of the gear pump reaches a preset value, the solenoid valve opens the hydraulic oil tank and outputs the hydraulic oil in the hydraulic oil tank to the hydraulic cylinder.

[0006] The beneficial effects of this utility model are as follows: the motor, gear pump, hydraulic oil tank, and solenoid valve, in conjunction with the hydraulic cylinder, facilitate the formation of a hydraulic lifting device. Compared with the worm gear mechanical transmission in the prior art, it has less wear, a longer service life, and lower operating costs. At the same time, the scissor lift mechanism facilitates the smooth lifting and lowering of the cathode plate hanging mechanism and the cathode plate, improving the stability during the lifting and lowering process. The active drive mechanism and the driven drive mechanism facilitate the displacement of the entire device on the displacement track, thereby realizing the automated operation of the metallurgical process.

[0010] Furthermore, the sliding device includes a slide rail and a slider. The slide rail is mounted on the mounting bracket, and the slider is slidably mounted on the slide rail. The bottom end of the rod-shaped structure that makes up the scissor lift is hinged to the slider. The output shaft of the hydraulic cylinder is connected to the slider through a transmission rod, driving the slider to slide on the slide rail.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the movement of the slider on the slide rail is conducive to driving the bottom end of one of the rod-shaped structures that make up the scissor lift to slide. This rod-shaped structure is also hinged to the slider, which is conducive to the rotation of this rod-shaped structure around the slider as the axis. At the same time, in conjunction with another rod-shaped structure hinged to the fixed block, the stable lifting and lowering adjustment of the top plate of the scissor lift can be achieved.

[0012] Furthermore, the cathode plate hanging mechanism includes a hanging plate and a limiting plate. The limiting plate is vertically installed on the side wall of the hanging plate, and the top of the limiting plate is provided with multiple limiting grooves. The lifting lugs of the cathode plate are adapted to be disposed in the limiting grooves.

[0013] The beneficial effects of adopting the above-mentioned further solution are: the lifting lugs of the cathode plate are adapted to be set in the limiting groove, which is conducive to lifting and lowering the cathode plate through the lifting and lowering mechanism, while avoiding the cathode plate from shaking during the lifting and lowering process.

[0014] Furthermore, the bottom end of the connecting rod is connected to the hanging plate.

[0015] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the transmission of the lifting and lowering of the top plate to the hanging plate through the connecting rod, thereby realizing the lifting and lowering of the cathode plate hanging mechanism and the cathode plate.

[0016] Furthermore, the mounting frame is a rectangular ring structure, with the two fixed blocks and the two sliding devices arranged opposite each other on two opposite sides of the mounting frame, and the two active drive mechanisms and the two driven drive mechanisms respectively arranged at both ends of the sides of the mounting frame.

[0017] The beneficial effects of adopting the above-mentioned further scheme are: the two fixed blocks and the two sliding devices are all arranged opposite each other, which is conducive to the synchronous lifting and lowering of the two scissor lifts under the drive of the drive linkage; the arrangement of the two active drive mechanisms and the two driven drive mechanisms on the mounting frame is conducive to the displacement of the entire device by cooperating with the two parallel displacement tracks.

[0018] Furthermore, the active drive mechanism includes a drive motor, a drive wheel, and a fixed plate. The fixed plate is mounted on the side of the mounting bracket, the drive motor is mounted on the fixed plate, and its output shaft is connected to the drive wheel.

[0020] Furthermore, the driven mechanism includes a driven housing and a driven wheel. The driven housing is mounted on the side of the mounting bracket, and the driven wheel is rotatably disposed within the driven housing and slidably mounted on the displacement track.

[0021] The beneficial effect of adopting the above-mentioned further scheme is that the driven wheel can slide on the displacement track under the drive of the driving wheel, thereby driving the entire device to move.

[0022] Furthermore, the anti-deviation mechanism includes a mounting plate and two rollers. The mounting plate is an L-shaped plate structure mounted on the side wall of the driven housing. The rollers are disposed on the mounting plate, and the displacement track is disposed between the two rollers. The rollers are in rolling connection with the side wall of the displacement track.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the two rollers are rolled in connection with the side wall of the displacement track, which helps to prevent the driven wheel from deviating from the displacement track when it slides on the displacement track, thereby improving the stability of the entire device when it slides on the displacement track.

[0033] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0034] like Figure 1 As shown, a hydraulic lifting device for the smelting industry includes: a power mechanism 1, a hydraulic cylinder 2, a scissor lift mechanism 3, two cathode plate hanging mechanisms 4, a mounting frame 5, two active drive mechanisms 6, two driven drive mechanisms 7, and two anti-deviation mechanisms 8. The two cathode plate hanging mechanisms 4 are arranged side-by-side below the scissor lift mechanism 3 and are detachably connected to multiple cathode plates 9. The scissor lift mechanism 3 is mounted on the mounting frame 5 and connected to the hydraulic cylinder 2. The power mechanism 1 is mounted on the mounting frame 5 and connected to the hydraulic cylinder 2. The active drive mechanisms 6 and 7 are connected to the driven drive mechanisms 8. The driven mechanisms 7 are respectively disposed at both ends of the mounting frame 5 and are slidably connected to the displacement track. The two anti-deviation mechanisms 8 are respectively installed on the two driven mechanisms 7 and are slidably connected to the displacement track. The power mechanism 1 includes a power motor, a gear pump, a hydraulic oil tank and a solenoid valve. The power motor is connected to the gear pump, the hydraulic oil tank is connected to the hydraulic cylinder 2, and the solenoid valve is disposed on the hydraulic oil tank. When the output pressure of the gear pump reaches a preset value, the solenoid valve opens the hydraulic oil tank and outputs the hydraulic oil in the hydraulic oil tank to the hydraulic cylinder 2.

[0035] It should be noted that the technical solution of this utility model also includes a control mechanism, which is a single-chip microcomputer or a PLC (Programmable Logic Controller). The control mechanism is connected to the power motor and the active drive mechanism 6 in the power mechanism 1. The communication connection between the control mechanism and the power motor and the active drive mechanism 6 in the power mechanism 1 is existing technology.

[0036] The solenoid valve is either a mechanical solenoid valve or an electronic solenoid valve. When the solenoid valve is a mechanical solenoid valve, the output pressure of the gear pump gradually increases to a preset value. Since the preset pressure value is greater than the opening pressure of the solenoid valve, the solenoid valve is opened. When the solenoid valve is an electronic solenoid valve, it also needs to be used in conjunction with a pressure sensor and the control mechanism. When the pressure sensor detects that the output pressure is greater than the preset value, the solenoid valve is opened by the control mechanism.

[0037] The displacement trajectory is not shown in the illustration.

[0038] The beneficial effects of this utility model are as follows: the motor, gear pump, hydraulic oil tank, and solenoid valve, in conjunction with the hydraulic cylinder, facilitate the formation of a hydraulic lifting device. Compared with the worm gear mechanical transmission in the prior art, it has less wear, a longer service life, and lower operating costs. At the same time, the scissor lift mechanism facilitates the smooth lifting and lowering of the cathode plate hanging mechanism and the cathode plate, improving the stability during the lifting and lowering process.
