Abstract
Description
Technical Field
[0001] This utility model relates to the field of correction detection equipment, and in particular to a heat insulation structure for a metal plate strip correction sensor. Background Technology
[0002] A utility model patent with application number CN201420189726.X discloses a capacitive metal strip position detection sensor, comprising a frame consisting of a left mounting plate, a right mounting plate, an upper mounting plate, and a lower mounting plate. The upper and lower mounting plates are parallel to each other, and their ends are connected to the left and right mounting plates, respectively. Each of the inner surfaces of the upper and lower mounting plates has a receiving electrode and two transmitting electrodes, or two transmitting electrodes and one receiving electrode, respectively. The receiving and transmitting electrodes are insulated from the upper or lower mounting plates. A signal modem is also provided on the frame and is conductively connected to the receiving and transmitting electrodes. The sensor detects the deviation of the metal strip during its movement using the principle of electromagnetic induction. However, this sensor is currently only suitable for detecting the position of metal strips operating at room temperature. When position detection is required for strips exiting a high-temperature furnace, the high temperature of the strip is conducted to the signal modem through the transmitting / receiving electrodes, which can damage the instrument's components, making it impossible to detect the position of the metal strip exiting the high-temperature furnace. Utility Model Content
[0003] To overcome the above problems, this utility model provides a heat insulation structure for a metal plate strip with a correction sensor. The technical solution adopted by this utility model to solve its technical problem is as follows:
[0004] A heat-insulating structure for a metal plate with a correction sensor includes a mounting frame, an electrode plate mounted on the mounting frame, a high-temperature resistant fixing component at one end of the electrode plate, a heat-insulating conductive component inside the high-temperature resistant fixing component, a wire connected to one end of the heat-insulating conductive component, the wire passing through the electrode plate, and the other end of the heat-insulating conductive component being electrically connected to an electrical control box via a high-temperature resistant shielded cable.
[0005] Furthermore, the high-temperature shielded cable includes a metal flexible tube, in which the cable is fitted.
[0006] Furthermore, the thermally insulating conductive component includes a ceramic insulating shell, within which a spark plug is disposed.
[0007] Furthermore, the conductor is made of high-temperature and nitriding resistant austenitic stainless steel, and one end of the conductor is threadedly connected to the heat-insulating conductive component.
[0008] Furthermore, the high-temperature resistant fasteners are made of carbon structural steel.
[0009] Furthermore, the control box includes a circuit board assembly and a signal modulation and conditioning unit.
[0010] The beneficial effects of this utility model are as follows:
[0011] This heat insulation structure includes a mounting frame with an electrode plate on it. One end of the electrode plate has a high-temperature resistant fixing component, and a heat-insulating conductive component is installed inside the high-temperature resistant fixing component. One end of the heat-insulating conductive component is connected to a wire, which passes through the electrode plate. The other end of the heat-insulating conductive component is electrically connected to the control box via a high-temperature resistant shielded cable. This heat insulation structure connects the wire and the high-temperature resistant shielded cable through the heat-insulating conductive component and can isolate the heat conducted from the electrode plate. Furthermore, the high-temperature resistant shielded cable has a certain length and connects to the control box, allowing the control box to be placed away from heat sources. Any remaining heat cannot be conducted to the control box through the high-temperature resistant shielded cable. Thus, the instruments in the control box are always at a suitable operating temperature and will not be damaged by the high temperature of the metal plate. Attached Figure Description

[0017] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the utility model "a heat insulation structure for a metal plate strip correction sensor" is provided in conjunction with the accompanying drawings.
[0018] See Figure 1 and Figure 2In this embodiment, the heat insulation structure of the metal plate with the correction sensor includes a fixing frame 100. The upper and lower ends of the fixing frame 100 are provided with electrode plates 101. The electrode plates 101 are divided into a transmitting electrode plate and a receiving electrode plate. One end of the electrode plate 101 is provided with a high-temperature resistant fixing member 102. A heat-insulating conductive member 103 is provided inside the high-temperature resistant fixing member 102. One end of the heat-insulating conductive member 103 is connected to a wire 104. The wire 104 passes through the electrode plate 101. The other end of the heat-insulating conductive member 103 is electrically connected to the electrical control box 106 through a high-temperature resistant shielded cable 105. When the tracking sensor operates on high-temperature metal strip, the heat-insulating conductive element 103 effectively isolates most of the heat transferred from the electrode plate 101, preventing high heat from being transferred to the high-temperature shielded cable 105. High temperatures are also prevented from being transferred to the control box 106 via the high-temperature shielded cable 105. Furthermore, the high-temperature shielded cable 105 has a certain length, preferably greater than 6 meters, allowing the control box 106 connected via the high-temperature shielded cable 105 to be placed far away from high-temperature heat sources, ensuring that the instruments inside are not affected by high temperatures and cannot operate. The metal strip tracking sensor using this heat-insulating structure can meet the requirements of metal strip tracking operations in high-temperature environments.
[0019] More specifically, in this embodiment, the high-temperature shielded cable 105 includes a metal flexible tube, in which a cable is sleeved. The metal flexible tube protects the cable, and the cable covered by the metal flexible tube is more wear-resistant, heat-resistant, and flexible, making it convenient to connect to the electrical control box 106 in different locations.
[0020] Furthermore, in this embodiment, the heat-insulating conductive element 103 includes a ceramic insulating shell, within which a spark plug is disposed. The ceramic insulating shell is made of heat-insulating ceramic, which has excellent heat insulation properties. The spark plug serves to connect the high-temperature shielded cable 105 and the wire 104, improving the structural strength of the connection. Preferably, one end of the wire 104 is threadedly connected to the heat-insulating conductive element 103, improving the stability of the connection. In this embodiment, the wire 104 is preferably made of high-temperature resistant and nitriding-resistant stainless steel, which has excellent heat and corrosion resistance, improving the service life of the sensor.
[0021] More specifically, in this embodiment, the high-temperature resistant fastener 102 is made of carbon structural steel, which is low in cost and has excellent structural strength and high-temperature resistance, so as to support the thermal insulation conductive component 103.
[0022] It should be noted that, in this embodiment, the electronic control box 106 includes various electronic components / electronic instruments required by the existing correction sensor, including at least a circuit board assembly and a signal modulation conditioner.
