Description

Technical Field

[0001] This utility model relates to the field of steelmaking, and in particular to an emergency protection device for a control box. Background Technology

[0002] In the continuous casting process of steel plants, control boxes are often installed near the ladles and tundishes for easy operation. Operators operate these machines during inspections, and the control box is usually positioned with its operating surface facing the ladle. Due to the frequent occurrence of emergencies such as ladle penetration or steel leakage, the control box is usually placed about 10 to 20 meters away from the ladle. However, in actual production, sudden events can cause high-temperature molten steel to splash everywhere, often accompanied by high-temperature blast waves. These blast waves can be highly destructive to the control panel (such as touch screens and buttons) on the control box. Since the control box cannot be moved after installation, its position is often not changed.

[0003] Therefore, in order to prevent the components on the control box from being damaged by air blasts, an emergency protection device for the control box is needed. Utility Model Content

[0004] The main purpose of this utility model is to provide an emergency protection device for a control box, which facilitates operation by raising the protective baffle and shields the control panel when released, effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An emergency protection device for a control box includes a control box and further includes, The bracket is fixed to the top of the control box; A protective baffle is installed on one side of the control panel of the control box and is hinged to the upper end of the bracket via a pivot. Normally, it is pulled up in an inclined state to avoid the operator's field of vision. The traction assembly includes a traction cable that connects to the outside of the protective barrier; Control device for locking or releasing the traction cable; When the traction cable is released, the protective baffle rotates around the control box under the action of gravity until it vertically covers the control box to form a shielding barrier.

[0006] Furthermore, the control device is a horizontally arranged cylinder, the end of which is releasably connected to the end of the traction cable. When the control device releases the constraint on the traction cable, the protective baffle falls freely.

[0007] Furthermore, it also includes a counterweight system, wherein the traction cable passes through a guide ring fixed on the bracket and then winds around to the back of the control box to connect to the counterweight system.

[0008] Furthermore, a protrusion is fixedly connected to the outer surface of the protective baffle, and the traction cable is fixed to the protrusion.

[0009] Furthermore, the counterweight system includes a guide tube fixed vertically to the back of the control box and a counterweight block slidably disposed within the guide tube. The end of the traction cable is fixed to the upper end of the counterweight block. A radially arranged locking hole is provided on the side wall of the guide tube. The piston rod of the control device is inserted into the locking hole and laterally blocked on the upper surface of the counterweight block.

[0010] Furthermore, a buffer limit block is fixed on the bracket, which is located on the vertical falling path of the protective baffle to prevent the protective baffle from hitting the control panel.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This utility model features a protective baffle that is rotatably mounted on the upper part of one side of the control panel of the control box. In normal operation, the protective baffle is lifted and tilted to avoid the operator's field of vision and facilitate operation. When it is necessary to shield the control panel, the traction cable is released, allowing the protective baffle to rotate under gravity and shield the control panel when it is in a vertical position.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1-3 As shown, an emergency protection device for a control box includes a control box 10, and also includes... Bracket 20 is fixed to the top of control box 10; A protective baffle 30 is located on one side of the control panel of the control box 10 and is hinged to the upper end of the bracket 20 via a pivot. Normally, it is pulled up in an inclined state to avoid the operator's field of vision. The traction assembly 40 includes a traction cable 401 connected to the outside of the protective baffle 30; Control device 50, used to lock or release the traction cable 401; When the traction cable 401 is released, the protective baffle 30 rotates around the control box 10 under the action of gravity until it vertically covers the control box 10 to form a shielding barrier.

[0015] Specifically, the bracket 20 can be welded from channel steel and installed above the control box 10. The protective baffle 30 is welded and fixed to the rotating shaft. The rotating shaft is rotatably connected to the bracket 20 on one side of the control panel of the control box 10. The protective baffle 30 is lifted by the traction cable 401. Under normal conditions, the control device 50 locks the traction cable 401, and the free end of the protective baffle 30 is pulled up above the rotating shaft to avoid the operator's field of vision. When it is necessary to block the view, the control device 50 releases the traction cable 401, so that the protective baffle 30 can block the control panel of the control box 10 after it falls.

[0016] Furthermore, the control device 50 is a horizontally arranged cylinder, the end of which is releasably connected to the end of the traction cable 401. When the control device 50 releases the constraint on the traction cable 401, the protective baffle 30 falls freely.

[0017] A further solution is that, in order to facilitate the re-lifting of the protective baffle 30, the device also includes a counterweight system 60. The traction cable 401 passes through the guide ring 201 fixedly installed on the bracket 20 and then winds around to the back of the control box 10 to connect to the counterweight system 60. The setting of the counterweight system 60 makes it easier to lift the protective baffle 30, and the setting of the guide ring 201 can effectively limit the movement position of the traction cable 401.

[0018] Furthermore, to facilitate the fixing of the traction cable 401, a protrusion 301 is fixedly connected to the outer side of the protective baffle 30, and the traction cable 401 is fixed to the protrusion 301.

[0019] A further embodiment is that the counterweight system 60 includes a guide cylinder 601 fixed vertically to the back of the control box 10 and a counterweight block 602 slidably disposed within the guide cylinder 601. The end of the traction cable 401 is fixed to the upper end of the counterweight block 602. A radially arranged locking hole 6011 is provided on the side wall of the guide cylinder 601. The piston rod of the control device 50 is inserted into the locking hole 6011 and laterally blocked on the upper surface of the counterweight block 602. The guide cylinder 601 and the counterweight block 602 can be configured as cylindrical, which makes it easier for the counterweight block 602 to be inserted into the guide cylinder 601. At the same time, a guide tube can be welded to the locking hole 6011 to facilitate the insertion of the piston rod.

[0020] A further solution is to prevent the protective baffle 30 from directly impacting the control panel of the control box 10 when it falls and rotates. A buffer limit block 202 is fixedly installed on the bracket 20. It is located on the vertical falling path of the protective baffle 30 and is used to prevent the protective baffle 30 from impacting the control panel. The buffer limit block 202 is located below the rotating shaft of the protective baffle 30 and is fixed to the inner side of the bracket 20.

[0021] Specifically, when a steel leak occurs, the operator quickly moves away from the control box 10 to a safe area and activates the button of the control device 50 (i.e., the cylinder), causing its piston rod to retract. Under unobstructed action, the counterweight 602 rises due to the falling of the protective baffle 30 under gravity. The protective baffle 30 can quickly shield the control box 10. The electrical components installed in the control box and the cylinder control method in this patent are all conventional technical means and will not be described in detail here.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
