[0002] Existing refining furnace rotation mechanisms are primarily used in dual-station refining furnaces. After the conductive crossbar on the rotation mechanism, holding the electrode, rotates from the intermediate position to the smelting position, a locking device is required to precisely lock the conductive crossbar, ensuring the electrode is accurately inserted into the refining furnace cover for smooth smelting.

[0003] At present, the locking device structure of the refining furnace rotating mechanism mostly adopts vertical pin-type locking; the relevant device is mainly composed of a hydraulic cylinder, a pin shaft, a positioning block, etc.; the cylinder, the pin shaft, etc. are fixed on the outside of the rotating mechanism, and the positioning block is fixed on the platform foundation; the hydraulic cylinder is installed vertically downward, and the hydraulic cylinder piston rod is connected to the pin shaft. When the rotating mechanism reaches the required position, the pin shaft is inserted into the hole of the lower positioning block through the cylinder to lock the entire rotating mechanism; this mechanism has obvious disadvantages. Since the pin shaft and the fixed block require a certain matching accuracy, when the positioning of the rotating mechanism deviates, the locking mechanism cannot be normally inserted into the positioning block; in addition, due to the high positioning requirements, installation and debugging are more difficult.

[0004] Therefore, it is necessary to provide a locking mechanism for a refining furnace. Utility Model Content

[0023] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0024] See also Figures 1 to 3 , Figure 1 This is a three-dimensional diagram of a preferred embodiment of a locking mechanism for a refining furnace according to the present utility model; Figure 2 A three-dimensional diagram of the preferred embodiment of the stopper and the mounting cylinder of the utility model; Figure 3 This is a three-dimensional diagram of the best embodiment of the installation cylinder and the locking member of the utility model. Figures 1 to 3 As shown, at least one embodiment provides a locking mechanism for a refining furnace, comprising: a telescopic assembly 1, a rotating assembly 3 and a locking member 6, wherein an L-shaped slide 2 is fixed to the output end of the telescopic assembly 1, a portion of the rotating assembly 3 is arranged on the L-shaped slide 2, and a mounting tube 4 is fixed to the output end of the rotating assembly 3, and a plurality of stop members 5 are connected to the mounting tube 4 through the locking member 6.

[0025] 1. Telescopic component 1

[0026] The telescopic assembly 1 includes a hydraulic cylinder, which is suitable for driving the L-shaped slide 2 to move forward or backward. Specifically, the hydraulic cylinder is used to move the L-shaped slide 2 and the components installed on the L-shaped slide 2 forward and backward.

[0027] 2. L-shaped slide 2

[0028] The L-shaped slide 2 is composed of an L-shaped plate and a slider. The L-shaped plate includes a vertical baffle and a horizontal plate. A slider is provided at the bottom of the horizontal plate. There is a corresponding slide rail on the use surface of the locking mechanism. It should be additionally supplemented that the hydraulic cylinder is connected to the vertical baffle, and the rotating component 3 is installed on the horizontal plate.

[0029] 3. Rotating component 3

[0030] The rotating assembly 3 includes a servo motor, part of which is fixed on the L-shaped slide 2. The output end of the servo motor is fixedly connected through a rotating shaft and a mounting cylinder 4. The servo motor is used to rotate the eccentric gear. Specifically, when the rotating part that drives the refining furnace to change its inclination angle rotates to a certain angle, the rotating part includes a gear, and the hydraulic cylinder pulls the servo motor to a suitable position. Then the servo motor rotates to engage the eccentric gear and the gear that drives the refining furnace to rotate, thereby completing the locking effect of the refining furnace. Compared with the latch-type locking in the related art, the horizontal pressure block type increases the redundant range of the device in the horizontal positioning, improves the locking stability, and reduces the difficulty of operation.

[0031] 4. Install the tube 4

[0032] The mounting tube 4 is fixed to the output end of the servo motor. A plurality of cross holes 41 are provided on the mounting tube 4. Every two cross holes 41 form a group. The cross holes 41 in a group are used to clamp a stop member 5. That is, a group of cross holes 41 corresponds to an eccentric gear. The eccentric gear is fixed between two cross holes 41 in a group, so that the nuts on both sides can respectively abut against its surface.

[0033] 5. Stopper 5

[0034] The stopper 5 includes an eccentric gear, which is fixed on the mounting barrel 4. The eccentric gear can be engaged with the gear that drives the refining furnace to rotate by rotating, so as to achieve angle locking of the refining furnace.

[0035] 6. Locking piece 6

[0036] The locking member 6 includes a first screw 61 and a second screw 62. The eccentric gear is provided with a cross-shaped first screw 61 and a second screw 62 on both sides. The nuts at the leading and trailing ends of the first and second screws 61, 62 can abut against the eccentric gear when installed. The first and second screws 61, 62 extend through the cross hole 41, respectively. A threaded hole is provided at the center of the first screw 61, through which the second screw 62 is adapted to extend. Both the first and second screws 61, 62 have a head and a tail. The head end is an integral nut, while the tail end is a movable nut, which abuts against the side wall of the stop member 5. The first and second screws 61, 62 intersect within the mounting barrel 4 to form a triangular support structure. That is, a triangular support structure is formed between the cross-shaped first and second screws 61, 62 and the inner wall of the mounting barrel 4 to enhance the prestressed strength of the mounting barrel 4.

[0037] To sum up, the eccentric gear allows the rotating parts of the refining furnace to be locked in a horizontal pressure block manner, which increases the redundant range of the device in the horizontal positioning, improves the locking stability, and reduces the difficulty of operation; by providing the locking member 6, the support strength is improved by offsetting the side of the eccentric gear, and a triangular support structure is formed to improve the overall support strength of the mounting cylinder 4, thereby effectively maintaining the stability during the locking process of the refining furnace.

[0038] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention.
