Abstract
Description
Technical Field

[0002] In the industrial production process, electric furnace is a commonly used heat treatment equipment for heating, melting, sintering and other processes of workpieces. Electric furnace is generally composed of a fixed furnace body and a movable furnace body, wherein the movable furnace body can be moved and positioned as needed to facilitate the processing of workpieces of different sizes and shapes. In order for the movable furnace body to work properly and maintain good electrical performance, it must be provided with a reliable power supply.
[0003] The traditional way of connecting the electric furnace to the power supply is mainly through hard connection structures, such as bolt connection or welding. However, this method has some problems: first, the hard connection structure is easily affected by mechanical stress, resulting in poor contact or damage, which affects the working efficiency and service life of the electric furnace; second, the hard connection structure is often difficult to quickly disassemble and assemble, which increases the cost and time of maintenance and overhaul.
[0004] In order to solve these problems, many new solutions for connecting the electric furnace to the power supply have emerged in recent years. One common method is to use a sliding contact structure to connect and disconnect the electric furnace through the relative movement between the slider and the track. The advantage of this method is that it can achieve rapid disassembly and assembly, reducing the time and cost of manual operation. However, the sliding contact structure also has some disadvantages, such as the large friction between the slider and the track, which is prone to wear and noise, and may become stuck under high load conditions.

[0038] The following is combined with Figure 1-4 The utility model patent is further described in detail.
[0039] like Figure 1 to Figure 2 As shown, an embodiment of the utility model discloses a quick power connection device for an electric furnace, comprising a female power connection socket 3 arranged on a fixed furnace body 1 of the electric furnace and a male power connection socket 4 arranged on a movable furnace body 2 of the electric furnace, the female power connection socket 3 is installed on the movable furnace body 2 through a fixed socket 10, and the female power connection socket 3 is connected to a power source; the male power connection socket 4 is installed on the fixed furnace body 1 through the fixed socket 10, and the male power connection socket 4 is electrically connected to a resistor.
[0040] The movable furnace body 2 is driven to dock with the fixed furnace body 1 through the transmission mechanism. After the movable furnace body 2 is docked with the fixed furnace body 1, the female power socket 3 is docked with the male power socket 4, so that the resistance belt of the movable furnace body 2 is connected for heating.
[0041] like Figure 2-Figure 4 As shown, the power connection mother seat 3 includes a first conductive plate 301, and the first conductive plate 301 is also connected to the conductive plate driving mechanism. In this embodiment, the conductive plate driving mechanism includes a first mounting seat 302, a guide column 5, an electromagnet 303 and a limit seat 304; one end of the guide column 5 is connected to the first conductive plate 301, and the other end of the guide column 5 can move on the first mounting seat 302. The electromagnet 303 is installed on the guide column 5, and a spring 6 is also provided between the electromagnet 303 and the first mounting seat 302. The end of the electromagnet 303 away from the first mounting seat 302 is limited by the limit seat 304; when the electromagnet 303 is energized, the electromagnet 303 drives the guide column 5 to move toward the second conductive plate 401, and the electromagnet 303 is adsorbed on the first mounting seat 302; when the electromagnet 303 loses power, the electromagnet 303 is disengaged from the first mounting seat 302, and the electromagnet 303 returns to its original position.
[0042] The power socket 4 includes a second conductive plate 401 and a floating mechanism connected to the second conductive plate 401 . The second conductive plate 401 is arranged parallel to the first conductive plate 301 . The second conductive plate 401 can move toward or away from the first conductive plate 301 through the floating mechanism.
[0043] In this embodiment, the floating mechanism includes a second mounting seat 402, a guide post 5, a connecting plate 403 and a spring 6; one end of the guide post 5 is connected to the second conductive plate 401, and the other end can move on the second mounting seat 402. The connecting plate 403 is fixed on the guide post 5, the spring 6 is sleeved on the guide post 5, and the spring 6 is arranged between the connecting plate 403 and the second mounting seat 402. The floating mechanism adopts mechanical restrictions of the connecting plate 403 and the spring 6, has a stable structure, is resistant to high temperatures, and ensures the stability of actual operation.
[0044] In this embodiment, the first conductive plate 301 and the second conductive plate 401 are both rectangular structures. By arranging the first conductive plate 301 and the second conductive plate 401 for docking, the contact area of the conductive plates is large, and they can still have good contact after long-term use. In addition, by connecting a floating mechanism to the second conductive plate 401, fine-tuning floating is achieved to ensure that the conductive plates are in close contact under pre-pressure when the movable furnace body 2 is docked, thereby reducing hard impact wear.
[0045] In order to accurately determine whether the movable furnace body 2 has moved into position, so as to more accurately dock the first conductive plate 301 with the second conductive plate 401, the electric furnace quick power connection device of this embodiment further includes an induction device. When the movable furnace body 2 moves into position, the induction device triggers a signal, so that the electromagnet 303 is energized, thereby driving the first conductive plate 301 to move toward the second conductive plate 401, and tightly pressing the first conductive plate 301 with the second conductive plate 401. By providing the induction device, it is ensured that only when the movable furnace body 2 is accurately docked with the fixed furnace body 1, the electromagnet 303 will drive the first conductive plate 301 to move and tightly press against the second conductive plate 401, thereby improving the safety and accuracy of the system.
[0046] In this embodiment, the sensing device is a proximity switch (not shown in the figure) installed on the movable furnace body 2 and the fixed furnace body 1 respectively. When the movable furnace body 2 moves to the docking position with the fixed furnace body 1, the proximity switches installed on both will generate an induction signal to accurately determine the moment when the furnace bodies are docked. Once the position of the movable furnace body happens to make the two proximity switches enter the distance range of mutual induction, an electrical signal will be triggered, and this signal will then be transmitted to the control system, so that the electromagnet 303 is energized, thereby driving the first conductive plate 301 to move toward the second conductive plate 401, pressing the first conductive plate 301 against the second conductive plate 401, thereby ensuring the stability of the connection between the first conductive plate 301 and the second conductive plate 401.
[0047] like Figure 4 As described, a locking mechanism 7 is also provided between the female power socket 3 and the male power socket 4. When the movable furnace body 2 is moved into position, the locking mechanism 7 is triggered to lock, thereby limiting the relative movement between the male power socket 4 and the female power socket 3. By providing the locking mechanism 7 to function after the furnace bodies are docked, the movable furnace body 2 and the fixed furnace body 1 are physically locked, thereby preventing the relative movement of the power connection part due to vibration or other reasons during the operation of the electric furnace, thereby strengthening the overall stability of the electric furnace power connection device, and ensuring long-term safe operation in harsh industrial environments.
[0048] In this embodiment, the locking mechanism 7 includes a socket 71 provided on the male socket 4 and a plug 72 provided on the female socket 3. When the conductive plate driving mechanism drives the first conductive plate 301 and the second conductive plate 302 to be pressed against each other, the plug 72 is inserted into the socket 71. The locking mechanism 7 intervenes in time after the movable furnace body 2 and the fixed furnace body 1 are successfully docked, and the relative position between the movable furnace body 2 and the fixed furnace body 1 is locked through the delicate cooperation of the socket 71 and the plug 72.
[0049] An arc-shaped guide surface 8 is provided at one end of the second conductive plate 401 close to the fixed furnace body 2, and an arc-shaped guide surface 8 is also provided at one end of the first conductive plate 301 away from the fixed furnace body 1. By providing the arc-shaped guide surface, when the movable furnace body and the fixed furnace body are docked, the first conductive plate and the second conductive plate are initially in contact with each other, and interference and jamming between the first conductive plate and the second conductive plate can be avoided by the arc-shaped guide surface.
[0050] In order to further increase the stability of the electric furnace power connection, a conductive soft metal 9 is provided on one or both of the first conductive plate 301 and the second conductive plate 401, and a plurality of conductive soft metals 9 are distributed along the moving direction of the movable furnace body 2. By using conductive soft metal material, the wear resistance and conductivity of the conductive plate are increased, the contact wear during long-term use is further reduced, and the durability and safety of the power connection device are greatly improved.
[0051] The working process of the electric furnace quick power connection device of this embodiment is as follows:
[0052] The movable furnace body 2 is driven by the transmission mechanism to move into the fixed furnace body 1 for docking. During the movement, the first conductive plate and the second conductive plate are initially docked. At this time, due to the floating mechanism on the second conductive plate, it can be ensured that there is no interference or jamming between the first conductive plate and the second conductive plate.
[0053] When the movable furnace body 2 of the electric furnace moves into position, when the movable furnace body 2 moves to the docking position with the fixed furnace body 1, the proximity switches installed on the two will generate an induction signal to accurately determine the moment when the furnace bodies are docked. Once the position of the movable furnace body just makes the two proximity switches enter the distance range of mutual induction, an electrical signal will be triggered, and this signal will then be transmitted to the control system, so that the electromagnet 303 is energized, thereby driving the first conductive plate 301 to move toward the second conductive plate 401, and pressing the first conductive plate 301 against the second conductive plate 401. This allows the conductive plate and the second conductive plate to be stably electrically connected. The risk of loose contacts caused by thermal expansion and contraction and assembly errors is effectively reduced, while reducing the impact wear caused by hard contact. At this time, the plug 72 is inserted into the socket 71 to lock the relative position between the movable furnace body and the fixed furnace body.
[0054] The above are all preferred embodiments of the present utility model patent, and are not intended to limit the protection scope of the present utility model patent. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model patent should be covered within the protection scope of the present utility model patent.
