Description

Technical Field

[0001] This application relates to the field of soaking furnaces, and more particularly to a device for measuring the swing angle of a soaking furnace trolley. Background Technology

[0002] In the CSP hot rolling production process, a production method is adopted where two soaking furnaces (A and B) are configured with one finishing rolling line. During production, the continuously cast billet from line B is transported to line A after being connected by the two soaking furnace trolleys, and then conveyed into the rolling mill via roller conveyors on line A. When transferring the billet, the soaking furnace trolleys need to swing at a certain angle and accurately center. The centering of the soaking furnace trolleys is generally achieved by positioning pins at the end of the swing. In actual production, due to the large positioning deviation of the positioning pins and their inability to reflect the centering of the two trolleys, production accidents such as trolley slippage and rolling accidents are prone to occur. Furthermore, the soaking furnace trolleys are over 100 meters long, weigh nearly 200 tons, and have a rotation angle of about 15 degrees, resulting in a large swing radius. Ordinary angle sensors and large-distance displacement sensors are difficult to directly or indirectly measure the precise position of the trolleys during swing. Summary of the Invention

[0003] One of the purposes of this application is to provide a device for measuring the swing angle of a soaking furnace trolley, so as to solve the problem of inaccurate measurement of the swing angle of existing soaking furnace trolleys.

[0004] The technical solution of this application is:

[0005] A device for measuring the swing angle of a soaking furnace trolley includes a fixed bracket, an arc-shaped structural block, and a laser displacement sensor. The arc-shaped structural block is oscillatingly mounted on the bottom of the trolley near the pivot. The arc-shaped structural block has a first end and a second end, and its thickness gradually increases from the first end to the second end. The trolley is oscillatingly mounted on the pivot. The laser displacement sensor is vertically mounted on the top surface of the fixed bracket, directly below the arc-shaped structural block. When the trolley swings from 15° to 0°, the vertical distance between the laser displacement sensor and the arc-shaped structural block changes from 0 to Δh. The swing angle of the trolley is then determined. The relationship between the measured vertical spacing and the vertical spacing is as follows:

[0006]

[0007] In the formula, Δh is the change in height of the arc-shaped structural block in the vertical direction along the thickness direction; h is the real-time vertical distance between the laser displacement sensor and the arc-shaped structural block as measured in real time; h0 is the vertical distance between the surface of the arc-shaped structural block and the laser displacement sensor when the trolley rotates to 15°.

[0008] As one technical solution of this application, the vertical plane where the laser displacement sensor is located is in the same vertical direction as the vertical plane where the thickness direction of the arc-shaped structural block is located.

[0009] As one technical solution of this application, the end face of the first end is a trapezoidal surface, and the end face of the second end is a trapezoidal surface.

[0010] As one technical solution of this application, the arc-shaped structural block is arc-shaped, and both the inner and outer peripheral surfaces are arc-shaped surfaces.

[0011] As one technical solution of this application, both the trolley and the arc-shaped structural block rotate around the pivot.

[0012] As one technical solution of this application, the laser displacement sensor is detachably mounted on the top surface of the fixed bracket.

[0013] The beneficial effects of this application are:

[0014] The soaking furnace trolley swing angle measuring device of this application can solve the problem of inaccurate trolley angle measurement and is suitable for application in actual engineering projects. This device can effectively measure the position of the trolley, thereby achieving precise centering. It converts the angle measurement of the trolley into a displacement measurement through an arc-shaped structural block for angle measurement, making implementation simple and convenient. It provides a simple and feasible solution for high-precision measurement of the centering angle of the trolley in hot-rolled CSP soaking furnaces with large swing radii and large swing angles.

[0027] Example:

[0028] Please refer to Figure 1 (Refer to) Figures 2 to 3 This application provides a device for measuring the swing angle of a soaking furnace trolley, including a fixed bracket 5, an arc-shaped structural block 1, and a laser displacement sensor 4. The arc-shaped structural block 1 is swayably mounted on the bottom of the trolley 3 near the rotating shaft 2. The arc-shaped structural block 1 has a first end and a second end, and the thickness of the arc-shaped structural block 1 gradually increases from the first end to the second end. The trolley 3 is swayably mounted on the rotating shaft 2. The laser displacement sensor 4 is vertically mounted on the top surface of the fixed bracket 5, and the laser displacement sensor 4 is located directly below the arc-shaped structural block 1. The rotation angle range of the trolley 3 is specified. The rotation angle of the 3rd wheel is generally between 0-15°. As the angle gradually increases from 0 degrees, the distance between the arc-shaped structural block 1 and the laser displacement sensor 4 also gradually decreases. When the pendulum 3 swings from 15° to 0°, the vertical distance between the laser displacement sensor 4 and the arc-shaped structural block 1 varies from 0 to Δh. Therefore, the swing angle of the pendulum 3... The relationship between the measured vertical distance and the vertical distance can be expressed as:

[0029]

[0030] In the formula, Δh is the change in height of the arc-shaped structural block 1 in the vertical direction where the thickness direction is located; h is the real-time vertical distance between the laser displacement sensor 4 and the arc-shaped structural block 1 as measured in real time; h0 is the vertical distance between the surface of the arc-shaped structural block 1 and the laser displacement sensor 4 when the trolley 3 rotates to 15°.

[0031] The actual angle of the pendulum 3 can be calculated using this formula, thereby enabling precise position measurement of the pendulum 3 and achieving stable centering of the pendulum 3 along lines A and B.

[0032] It should be noted that the vertical plane where the laser displacement sensor 4 is located is in the same vertical direction as the vertical plane where the thickness direction of the arc-shaped structural block 1 is located.

[0033] Meanwhile, the end face of both the first and second ends is a trapezoidal surface. Furthermore, the arc-shaped structural block 1 is arc-shaped, with both its inner and outer circumferential surfaces being arc-shaped. Additionally, both the trolley 3 and the arc-shaped structural block 1 rotate around the pivot 2.

[0034] It should be noted that the laser displacement sensor 4 is detachably mounted on the top surface of the fixed bracket 5.

[0035] In summary, the soaking furnace trolley swing angle measuring device of this application can solve the problem of inaccurate trolley angle measurement and is suitable for application in practical engineering projects. This device can effectively measure the position of the trolley 3, thereby achieving precise centering of the trolley 3. It converts the angle measurement of the trolley 3 into a displacement measurement through the arc-shaped structural block 1 used for angle measurement. The implementation is simple and convenient, providing a simple and feasible solution for high-precision measurement of the centering angle of the trolley in a hot-rolled CSP soaking furnace with a large swing radius and large swing angle.

[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application.
