Description

Technical Field

[0001] This application relates to the field of steel rolling equipment technology, and in particular to a position detection device for steel rolling equipment. Background Technology

[0002] Steel rolling is a pressure processing process that changes the shape of steel ingots and billets between rotating rolls. Like other pressure processing methods, the purpose of steel rolling is to obtain the desired shape.

[0003] Publication number CN216095574U discloses a position detection device for steel rolling equipment. However, in the implementation of this solution, the lateral movement distance of the linkage rod is converted into the spiral advance and retreat distance of the mounting block on the lead screw. In order to ensure that the lead screw can display the lateral movement distance of the linkage rod, the lead screw needs to be relatively long, which requires a certain area of ​​space to install the lead screw, resulting in insufficient utilization of a lot of factory space and poor performance. Therefore, a position detection device for steel rolling equipment is proposed. Utility Model Content

[0004] To address the issues of existing position detection devices having a large footprint and poor performance, this application provides a position detection device for steel rolling equipment.

[0005] The position detection device for steel rolling equipment provided in this application adopts the following technical solution:

[0006] A position detection device for steel rolling equipment includes a mounting box. A rack is slidably connected inside the mounting box, and a connecting mechanism is provided at one end of the rack. A mounting plate is fixedly connected inside the mounting box. A rotating shaft passing through the surface of the mounting plate is rotatably connected inside the mounting plate. A main gear meshing with the rack is fixedly connected at one end of the rotating shaft, and a first transmission gear is fixedly connected at the end of the rotating shaft away from the main gear. Mounting shafts passing through the surface of the mounting plate are rotatably connected to both sides inside the mounting plate. A winding roller is fixedly connected to the surface of both mounting shafts, and a number bar is fixedly connected to the inner wall of both winding rollers.

[0007] By adopting the above technical solution, the positional change of the linkage rod can be transformed into the movement of the digital bar, making its movement information intuitive and more convenient for the operator to use.

[0008] Preferably, the surface of the mounting box is rotatably connected to a box door, and the surface of the box door is inlaid with a display screen.

[0009] By adopting the above technical solution and setting up the box door, it is convenient to maintain the components inside the installation box in subsequent work.

[0010] Preferably, the ends of the two number bars furthest from the take-up roller are fixedly connected to each other, and the numbers on the two number bars are positive and negative numbers respectively.

[0011] By adopting the above technical solution and using positive and negative numbers, it is easier for the operator to judge the direction of movement of the linkage.

[0012] Preferably, a fixed shaft is fixedly connected to the surface of the mounting plate, and a sliding roller that slides against the surface of the number bar is rotatably connected to the surface of the fixed shaft.

[0013] By adopting the above technical solution and using the sliding roller, the numbers on the digital bar are displayed below the recording device.

[0014] Preferably, a recording device is fixedly installed on the inner wall of the mounting box, the recording device is located directly above the sliding roller, and the recording device is electrically connected to the display screen.

[0015] By adopting the above technical solution, the detection results of the position of the steel rolling equipment are captured and recorded using video recording equipment, and transmitted to the display screen for the operator to view and understand.

[0016] Preferably, lighting lamps are fixedly connected to both sides of the inner wall of the mounting box.

[0017] By adopting the above technical solution, it is possible to supplement the lighting of the shooting environment inside the mounting box.

[0018] Preferably, a third transmission gear is fixedly connected to the end of each of the two mounting shafts away from the take-up roller, and two meshing fourth transmission gears are rotatably connected to the side of the mounting plate near the third transmission gear. The two fourth transmission gears are located between the two third transmission gears, and the two fourth transmission gears are respectively meshed with the two third transmission gears.

[0019] By adopting the above technical solution and setting the third and fourth transmission gears, the take-up and unwinding of the two take-up rollers are realized, ensuring the smooth movement of the digital strip.

[0020] Preferably, a second transmission gear that meshes with the first transmission gear is fixedly connected to the surface of one of the mounting shafts.

[0021] By adopting the above technical solution, the movement of the linkage rod is converted into the rotation of the take-up roller by utilizing the meshing of the first transmission gear and the second transmission gear.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] By utilizing the transmission of rack and pinion and main gear, the linear motion of the linkage rod is converted into a recordable rotational motion. Through transmission, two take-up rollers are driven to take up and unwind, which in turn drives the digital bar to move, causing the corresponding numbers on the recording device to change. This enables the recording and detection of positional changes in the steel rolling equipment. At the same time, it greatly reduces the overall size of the device, making it more convenient for staff to use. It is worthy of widespread application and promotion. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] This application discloses a position detection device for steel rolling equipment.

[0033] Reference Figures 1-4 A position detection device for a steel rolling mill includes a mounting box 1. A rack 4 that is linked with the steel rolling mill is slidably connected inside the mounting box 1. One end of the rack 4 is provided with a connecting mechanism 5 that is connected to the steel rolling mill. The connecting mechanism 5 has been specifically disclosed in the prior art, so it will not be discussed in detail here.

[0034] The surface of the mounting box 1 is rotatably connected to a door 2, which facilitates subsequent maintenance of the internal components of the mounting box 1 by subsequent staff. The surface of the door 2 is inlaid with a display screen 3 that can display position information, so that staff can clearly understand the position detection effect of the steel rolling equipment.

[0035] The mounting box 1 has a mounting plate 17 fixedly connected inside to provide a bearing space for the components. The mounting plate 17 has a rotating shaft 6 that passes through the surface of the mounting plate 17. One end of the rotating shaft 6 is fixedly connected to a main gear 18 that meshes with the rack 4. Thus, by setting the main gear 18, the linear motion of the linkage rod can be converted into the rotation of the rotating shaft 6, so as to facilitate the subsequent detection of the position change of the rolling mill equipment.

[0036] The end of the rotating shaft 6 away from the main gear 18 is fixedly connected to the first transmission gear 7 for transmission. Both sides inside the mounting plate 17 are rotatably connected to the mounting shaft 8 that passes through the surface of the mounting plate 17. The surfaces of the two mounting shafts 8 are fixedly connected to the take-up rollers 11 for winding and unwinding the digital strips 12. The inner walls of the two take-up rollers 11 are fixedly connected to the digital strips 12 that can digitally display the movement of the linkage rod. The digital strips 12 can be fixed to the take-up rollers 11 by adhesive or snapping, so as to facilitate the subsequent replacement of the digital strips 12. The digital strips 12 are cloth strips with numbers. The numbers of the two digital strips 12 are positive and negative numbers to indicate the movement direction of the linkage rod. The two digital strips 12 connected together have sufficient length to completely cover the position detection range of the rolling mill equipment. The displacement of each unit (e.g., 1 cm is 1 digital unit) ensures that the equipment can provide position information with sufficient accuracy. The ends of the two digital strips 12 away from the take-up rollers 11 are fixedly connected to each other, and the number here is zero, which is the starting point.

[0037] A second transmission gear 9, which meshes with the first transmission gear 7, is fixedly connected to the surface of a mounting shaft 8, thereby converting the movement of the linkage rod into the rotation of the take-up roller 11, which facilitates the digital recording of the position information of the subsequent steel rolling equipment.

[0038] A fixed shaft 15 is fixedly connected to the surface of the mounting plate 17 to support the sliding roller 16. The surface of the fixed shaft 15 is rotatably connected to the sliding roller 16, which slides against the surface of the number bar 12. A video recording device 14 for capturing and recording the numbers on the number bar 12 is fixedly installed on the inner wall of the mounting box 1. The video recording device 14 is located directly above the sliding roller 16 and is electrically connected to the display screen 3, so that the results captured and recorded by the video recording device 14 can be displayed on the display screen 3. This connection method is a mature existing technology and will not be discussed in detail here.

[0039] Both sides of the inner wall of the mounting box 1 are fixedly connected to lighting lamps 13 that can supplement the lighting of the internal environment of the mounting box 1, so as to ensure that the recording device 14 can record the numbers on the digital bar 12 more clearly. The inside of the mounting box 1 is equipped with a power supply, wires and other structures to provide power to the lighting lamps 13, the recording device 14 and the display screen 3. This is a conventional technical means, so it will not be discussed in detail here.

[0040] Two mounting shafts 8 are fixedly connected to third transmission gears 19 at their ends away from the take-up rollers 11. Two meshing fourth transmission gears 10 are rotatably connected to the mounting plate 17 near the third transmission gears 19. The two fourth transmission gears 10 are located between the two third transmission gears 19 and mesh with each of the three third transmission gears 19. Through the transmission of the two fourth transmission gears 10, the two third transmission gears 19 rotate in opposite directions, ensuring that the two take-up rollers 11 can maintain a one-to-one unwinding and winding state, guaranteeing the normal operation of the device. Furthermore, the two third transmission gears 19 and the two fourth transmission gears 10 have the same number of teeth, ensuring that the two take-up rollers 11 rotate at the same speed, guaranteeing the same winding and unwinding efficiency for the digital strips 12, preventing the digital strips 12 from becoming loose or broken, and ensuring the smooth operation of the device.

[0041] The implementation principle of the position detection device for a steel rolling mill according to an embodiment of this application is as follows: When detecting the position of the steel rolling mill, the device is first connected to the steel rolling mill using a connecting mechanism 5 (as disclosed in the prior art). Then, when the linkage rod moves, it drives the rack 4 to slide in the mounting box 1, thereby driving the main gear 18 and the rotating shaft 6 to rotate. At the same time, the rotation of the rotating shaft 6 synchronously drives the first transmission gear 7 to rotate, and through meshing connection, drives the second transmission gear 9 and a mounting shaft 8 to rotate. When one mounting shaft 8 rotates, through the setting of two third transmission gears 19 and two fourth transmission gears 10, the other mounting shaft 8 also rotates, and rotates in the opposite direction to the mounting shaft 8 with the second transmission gear 9 installed. This causes the two take-up rollers 11 to take up and unwind the digital bar 12 respectively, causing the number lifted by the sliding roller 16 to change, thereby digitally displaying the movement distance of the linkage rod. Then, the recording device 14 can shoot and record the changing values ​​on the digital bar 12 and transmit them to the display screen 3 so that the staff can clearly understand them.

[0042] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
