Description

Technical Field

[0001] The invention relates to the field of measurement technology, and in particular to a detection device and method for a sector frame of a continuous casting machine. Background Art

[0002] The continuous casting machine is a crucial equipment in steel production. It realizes the continuous casting of high-temperature molten steel into billets with specific cross-sectional shapes and dimensions. The core components of the continuous casting machine include inner and outer arc frames, cooling systems, protective covers, crystallizers, vibration mechanisms, secondary cooling devices, straightening machines and cutting machines. These components work together to ensure the efficient and stable operation of the continuous casting machine. The continuous casting machine segment is a key component in continuous casting production. It is located below the continuous casting machine crystallizer. It is mainly responsible for receiving billets with a certain billet shell thickness from the crystallizer and forcing the billet to be cooled by water spray or gas mist, so that the billet shell thickness continues to increase, and the "bulging" or steel leakage accidents caused by the static pressure of molten steel are avoided to the greatest extent. At the same time, the segment also plays a role in guiding and supporting the ingot chain, preventing the deformation of the billet and the deviation of the ingot chain. The segment is usually composed of a segment frame, a segment segment roller, a grid, a secondary cooling system and a centralized dry oil system. The segment frame is used to support the bending resistance of the roller and ensure the geometric shape of the billet.

[0003] The size of the sector frame directly affects the installation of the roller, so it is very important to detect the size between the frame and the roller. The prior art uses the method of measuring the distance between the roller and the frame one by one. This detection speed is very slow and manual operation is prone to errors. Summary of the invention

[0004] In view of the above technical problems, the present invention discloses a continuous casting machine sector frame detection device, including a bottom plate, a clamping assembly installed on the bottom plate, the clamping assembly clamps the frame, and a center measurement assembly is installed at both ends of the frame. The center measurement assembly includes a lower moving block, a lower vertical rod is fixedly installed on the lower moving block, a lower horizontal plate is fixedly installed on the lower vertical rod, a lower measuring plate is slidably installed on the lower vertical rod, a lower reset spring is fixedly installed between the lower measuring plate and the lower horizontal plate, and a lower positioning block is arranged on the lower side of the lower measuring plate. The lower moving block moves on the lower side of the frame, and the lower positioning block moves on the lower roller. Through the above technical scheme, the lower moving block can ensure that it is roughly the same as the position of the lower roller when it moves on the lower roller frame. The position of the upper end of each lower roller can be recorded by the lower measuring plate and the lower positioning block. The positions of the upper ends of all lower rollers can form a curve to see whether there are deviations. In this way, all lower rollers can be detected in one movement to see whether they are in the correct position.

[0005] Furthermore, the central measuring assembly also includes an upper moving block, on which an upper horizontal plate and an upper vertical rod are fixedly mounted, on which an upper measuring plate is slidably mounted, between which an upper return spring is fixedly mounted, and on which an upper positioning block is fixedly mounted, and on which an upper small spring moves in contact with the lower side of the upper roller.

[0006] Furthermore, the upper vertical rod is fixedly connected to the lower vertical rod, the lower horizontal plate is slidably connected to the lower vertical rod, the lower vertical rod is inserted into the lower horizontal plate, and a fixing plate is arranged on the lower side of the lower horizontal plate to fix the lower vertical rod and the lower horizontal plate.

[0007] Furthermore, the upper moving block is fixed with an upper small spring, the upper small spring is fixed with an upper matching plate, the upper matching plate is fitted with the upper side of the upper roller, the lower horizontal plate is fixed with a lower small spring, the lower matching plate is fixed with the lower small spring, the lower matching plate is fitted with the lower side of the lower roller. Through the above technical solution, the positions of the upper matching plate and the lower matching plate can be recorded to form an arc that can be verified with the arc formed by the upper positioning block and the lower positioning block, thereby ensuring accurate measurement and improving efficiency.

[0008] Furthermore, a center distance measuring component is installed on the center measuring component, and the center distance measuring component includes a distance measuring plate 1, and a distance measuring plate 1 is slidably installed on the lower vertical rod, and the distance measuring plate 1 is located on the upper side of the lower measuring plate, and a laser rangefinder is installed on the upper side of the distance measuring plate 1, and a receiver is fixedly installed on the lower side of the distance measuring plate 2, and a distance measuring plate 2 is slidably installed on the upper vertical rod, and the distance measuring plate 2 is located on the lower side of the upper measuring plate.

[0009] Furthermore, a small spring 2 is fixedly installed between the second ranging plate and the upper measuring plate, a compression spring 2 is fixedly installed on the upper vertical rod, a compression plate 2 is fixedly installed on the compression spring 2, and the compression plate 2 compresses the second ranging plate.

[0010] Furthermore, the upper measuring plate is provided with an unlocking hole 2, in which an unlocking block 2 is hinged, and the extrusion plate 2 is provided with a fixed block 2. The unlocking block 2 is restricted by the unlocking hole 2 and can only rotate downward, and the unlocking block 2 moves with the upper measuring plate and cooperates with the fixed block 2.

[0011] Furthermore, a small spring is fixedly installed between the distance measuring plate 1 and the lower measuring plate, a compression spring is fixedly installed on the lower vertical rod, a compression plate is fixedly installed on the compression spring, and the compression plate squeezes the distance measuring plate 1; an unlocking hole is provided on the lower measuring plate, an unlocking block is hinged in the unlocking hole, a fixed block is fixedly installed on the compression plate 1, the unlocking block 1 is restricted by the unlocking hole 1 and can only rotate upwards, and the unlocking block 1 cooperates with the fixed block 1 when following the movement of the lower measuring plate. Through the above technical solution, the distance between the upper roller and the lower roller can be measured. Since the upper roller and the lower roller are not corresponding along the radius, both the distance measuring plate 2 and the distance measuring plate 1 can stop and wait at the farthest point, and record the closest distance after the other party moves to the farthest point, so as to ensure the accuracy of the measurement data.

[0012] The present invention also discloses a method for detecting a continuous casting machine segment frame, comprising the following steps:

[0013] Step 1: Positioning: clamp the frame on the center measuring assembly and find the positioning point to record the position.

[0014] Step 2: Measure the arc deviation. Measure the upper end position of each lower roller to see if there is any deviation in the composed arc. Measure the lower end position of each upper roller to check if there is any deviation in the composed curve.

[0015] Step 3: Measure the distance between the lower end of the upper roller and the upper end of the lower roller to check whether it meets the distance standard.

[0016] Step 4: Compare the data measured at both ends of the upper roller and the lower roller to check whether the installation of both ends of the upper roller and the lower roller is consistent.

[0017] The beneficial effects of the present invention compared with the prior art are:

[0018] (1) Through the technical solution of the present invention, the lower moving block can move on the lower roller frame to ensure that the position is roughly the same as that of the lower roller. The position of the upper end of each lower roller can be recorded by the lower measuring plate and the lower positioning block.

In this way, all lower rollers can be detected in one movement to see if they are in the correct position.

[0019] (2) Through the technical solution of the present invention, the positions of the upper matching plate and the lower matching plate can form an arc that can be verified with the arc formed by the upper positioning block and the lower positioning block, thereby ensuring accurate measurement and improving efficiency.

[0020] (3) Through the technical solution of the present invention, the distance between the upper roller and the lower roller can be measured. Since the upper roller and the lower roller are not aligned along the radius, both the distance measuring plate 2 and the distance measuring plate 1 can stop and wait at the farthest point. After the other party also moves to the farthest point, the closest distance between the distance measuring plate 2 and the distance measuring plate 1 is recorded to ensure the accuracy of the measurement data.

DETAILED DESCRIPTION

[0032] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0033] like Figure 1-Figure 10The structural frame detection device of a continuous casting machine shown in the figure comprises a bottom plate 8, a clamping assembly 3 is mounted on the bottom plate 8, the clamping assembly 3 clamps the frame, and a center measuring assembly 1 is mounted at both ends of the frame. In this embodiment, the clamping assembly 3 comprises a transverse cylinder 1 301, the transverse cylinder 1 301 is fixedly mounted on the bottom plate 8, a moving rod 1 302 and a moving rod 2 303 are mounted on the output end of the transverse cylinder 1 301, a vertical cylinder 1 304 is fixedly mounted on the moving rod 1 302, and the vertical cylinder 1 304 is started to clamp the upper roller frame 6 and the lower roller frame 7, and the moving rod 2 303 is fixedly mounted on the moving rod 1 302. 03 is fixedly provided with a vertical cylinder 2 305, and the moving end of the vertical cylinder 2 305 clamps the upper roller frame 6 and the lower roller frame 7. Two horizontal cylinders 2 306 are provided on the bottom plate 8, and a vertical plate 307 is provided at the output end of the horizontal cylinder 2 306. A moving plate 309 is slidably provided on the vertical plate 307, and the moving plate 309 is driven by the vertical cylinder 308. A clamping claw 310 is provided on the moving plate 309, and the clamping claw 310 is also used for clamping. The entire frame is clamped by moving, and then positioned, so that the axis center of the lower roller 5 at the lowest point is placed at the zero position.

[0034] In this embodiment, the central measuring component 1 includes a lower moving block 101, on which a lower roller 102 is mounted, and the lower roller 102 is in contact with the lower roller frame 7 to drive the lower moving block 101 to move, and a lower vertical rod 105 is fixedly mounted on the lower moving block 101, and a lower horizontal plate 103 is fixedly mounted on the lower vertical rod 105, and a lower measuring plate 106 is slidably mounted on the lower vertical rod 105, and a lower return spring 104 is fixedly mounted between the lower measuring plate 106 and the lower horizontal plate 103, and a lower positioning block 107 is arranged on the lower side of the lower measuring plate 106, and the lower moving block 101 moves on the lower side of the frame, and the lower positioning block 107 moves on the lower roller 5. The cross-section of the lower positioning block 107 is a trapezoid, that is, it will drop when it moves between the two lower rollers 5, and then rise in the process of moving to the highest point of the lower roller 5, thus forming a wave-like motion trajectory, and the motion trajectory of the lower positioning block 107 is recorded by the system, and then a circular arc surface can be obtained according to the vertex drawing. Through the above technical scheme, the lower moving block 101 can ensure that it moves on the lower roller frame 7 at approximately the same position as the lower roller 5, and the position of the upper end of each lower roller 5 can be recorded by the lower measuring plate 106 and the lower positioning block 107. The positions of the upper ends of all the lower rollers 5 can form a curve to see if there are any deviations. In this way, all the lower rollers 5 can be detected in one movement to see if they are in the correct position.

[0035] In this embodiment, the central measuring component 1 also includes an upper moving block 108, on which an upper horizontal plate 110 and an upper vertical rod 111 are fixedly mounted, on which an upper measuring plate 113 is slidably mounted, between which an upper returning spring 112 is fixedly mounted the upper measuring plate 113 and the upper horizontal plate 110, on which an upper positioning block 114 is fixedly mounted, and on which an upper small spring 115 moves in contact with the lower side of the upper roller 4. The upper positioning block 114 has the same shape and working principle as the lower positioning block 107, and the measurement is also performed by recording the movement trajectory of the upper positioning block 114. The upper vertical rod 111 is fixedly connected to the lower vertical rod 105, and the lower horizontal plate 103 is slidably connected to the lower vertical rod 105. The lower vertical rod 105 is inserted into the lower horizontal plate 103, and a fixing plate 119 is set on the lower side of the lower horizontal plate 103 to fix the lower vertical rod 105 and the lower horizontal plate 103.

[0036] An upper small spring 115 is fixedly mounted on the upper moving block 108, an upper matching plate 116 is fixedly mounted on the upper small spring 115, the upper matching plate 116 is fitted with the upper side of the upper roller 4, a lower small spring 117 is fixedly mounted on the lower horizontal plate 103, a lower matching plate 118 is fixedly mounted on the lower small spring 117, and the lower matching plate 118 is fitted with the lower side of the lower roller 5. Through the above technical solution, the positions of the upper matching plate 116 and the lower matching plate 118 can be recorded to form an arc that is mutually verified with the arc formed by the upper positioning block 114 and the lower positioning block 107, thereby ensuring accurate measurement and improving efficiency.

[0037] In this embodiment, a center distance measuring component 2 is installed on the center measuring component 1, and the center distance measuring component 2 includes a distance measuring plate 203. A distance measuring plate 203 is slidably installed on the lower vertical rod 105, a sliding hole is set in the middle of the distance measuring plate 203, and the distance measuring plate 203 is sleeved on the lower vertical rod 105. The distance measuring plate 203 is located on the upper side of the lower measuring plate 106. A laser rangefinder 209 is installed on the upper side of the distance measuring plate 203. A distance measuring plate 212 is slidably installed on the upper vertical rod 111, a receiver 218 is fixedly installed on the lower side of the distance measuring plate 212, and the distance measuring plate 212 is located on the lower side of the upper measuring plate 113. A small spring 211 is fixedly installed between the second ranging plate 212 and the upper measuring plate 113, a spring hole 210 is provided on the upper measuring plate 113, the small spring 211 is fixedly installed in the spring hole 210, an extrusion spring 217 is fixedly installed on the upper vertical rod 111, an extrusion plate 213 is fixedly installed on the extrusion spring 217, the extrusion plate 213 extrudes the second ranging plate 212, an unlocking hole 215 is provided on the upper measuring plate 113, an unlocking block 214 is hinged in the unlocking hole 215, a fixed block 216 is provided on the extrusion plate 213, the unlocking block 214 is restricted by the unlocking hole 215 and can only rotate downward, and the unlocking block 214 moves with the upper measuring plate 113 and cooperates with the fixed block 216. A small spring 202 is fixedly installed between the ranging plate 203 and the lower measuring plate 106, a spring hole 201 is provided in the lower measuring plate 106, the small spring 202 is located in the spring hole 201, an extrusion spring 208 is fixedly installed on the lower vertical rod 105, an extrusion plate 204 is fixedly installed on the extrusion spring 208, and the extrusion plate 204 squeezes the ranging plate 203; an unlocking hole 206 is provided on the lower measuring plate 106, an unlocking block 205 is hinged in the unlocking hole 206, a fixed block 207 is fixedly installed on the extrusion plate 204, the unlocking block 205 is restricted by the unlocking hole 206 and can only rotate upwards, and the unlocking block 205 cooperates with the fixed block 207 when following the movement of the lower measuring plate 106. Through the above technical solution, the distance between the upper roller 4 and the lower roller 5 can be measured. Since the upper roller 4 and the lower roller 5 are not corresponding along the radius, the distance measuring plate 2 212 and the distance measuring plate 1 203 can stop and wait at the farthest point, and record the shortest distance after the other party also moves to the farthest point, so as to ensure the accuracy of the measurement data.

[0038] Working principle: Loosen the fixing plate 119 to place the upper moving block 108 and the lower moving block 101 against the upper roller frame 6 and the lower roller frame 7 respectively, then fix the fixing plate 119 for installation, then clamp the entire frame through the clamping assembly 3 and position it, place the lowest lower roller 5 at the zero position as the coordinate origin, then start the lower roller 102 and the upper roller 109 to drive the center measuring assembly 1 to move, the lower positioning block 107 always fits the lower roller 5, and the upper positioning block 114 fits the upper roller 4. Since the upper roller 4 and the lower roller 5 are not set correspondingly in radius, that is, when the lower positioning block 107 is at the top of the lower vertical rod 105, the upper positioning block 114 is between the two upper rollers 4. , and the movements are carried out alternately. When the lower positioning block 107 moves from between the two lower rollers 5 to the top of the lower roller 5, the lower measuring plate 106 rises accordingly. In this process, the lower measuring plate 106 pushes the distance measuring plate 203 to move upwards together, and in the process, the unlocking block 205 cooperates with the fixed block 207. The unlocking block 205 is blocked by the unlocking hole 206 and cannot rotate, so the fixed block 207 and the squeezing plate 204 are squeezed to compress the squeezing spring 208. At this time, the squeezing plate 204 no longer squeezes the distance measuring plate 203, but it has no effect. After the unlocking block 205 passes the fixed block 207, the squeezing plate 204 resumes squeezing the distance measuring plate 203. After reaching the highest point, the lower measuring plate 106 reverses The distance measuring plate 203 moves. At this time, the distance measuring plate 203 does not move, because it is squeezed by the squeezing plate 204, and the pulling force of the small spring 202 is always smaller than the friction between the squeezing plate 204 and the distance measuring plate 203. As long as the squeezing plate 204 is not released, the distance measuring plate 203 will not fall back. When the lower measuring plate 106 moves downward, the upper measuring plate 113 also starts to move downward, that is, it moves to the lowest end of the upper roller 4, and drives the distance measuring plate 212 to move to the lowest point. During the process, the unlocking block 214 contacts the fixed block 216. The unlocking block 214 is restricted by the unlocking hole 215 and cannot rotate, so the fixed block 216 is squeezed. At this time, the squeezing plate 213 no longer squeezes the distance measuring plate 212, but under the action of the small spring 211 The lower distance measuring plate 212 will not fall, the tension of the small spring 211 is greater than the gravity of the distance measuring plate 212, and after the unlocking block 214 passes the fixing block 216, the distance measuring plate 212 continues to reach the lowest end. Before this, the distance measuring plate 1 203 has reached the highest point. Therefore, after the distance measuring plate 212 reaches the lowest point, the distance between the distance measuring plate 212 and the distance measuring plate 1 203 is the minimum distance in this cycle. The laser rangefinder 209 and the receiver 218 are used for measurement. When the lower measuring plate 106 and the upper measuring plate 113 return, the unlocking block 1 205 and the unlocking block 214 will rotate and will not squeeze the squeezing plate 1 204 and the squeezing plate 2 213, so the distance measuring plate 212 and the distance measuring plate 1 203 will not be reset in advance.When the lower measuring plate 106 rises again, it will squeeze the fixed block 207 through the unlocking block 205. At this time, the squeezing plate 204 will no longer squeeze the distance measuring plate 203. The distance measuring plate 203 will fall quickly and fit with the upper end of the lower measuring plate 106, and then continue to rise with the lower measuring plate 106. The distance measuring plate 212 has the same movement principle as the distance measuring plate 203, and it will quickly reset and fit when the upper measuring plate 113 falls again. In this way, the distance between the upper roller 4 and the lower roller 5 can be measured. During the process, the lower matching plate 118 and the upper matching plate 116 also record the position through the same principle. There are position locators for recording the position on the lower matching plate 118, the upper matching plate 116, the upper positioning block 114, and the lower positioning block 107. The moving position and coordinates will be recorded relative to the zero point in the entire clamping assembly 3. The deviation can be detected by later calculation and image drawing.

[0039] A method for detecting a continuous casting machine segment frame comprises the following steps:

[0040] Step 1: Positioning: Place the frame on the center measuring component 1 for clamping, and find the positioning point to record the position.

[0041] Step 2: Measure the arc deviation, measure the upper end position of each lower roller 5 to see if the composed arc has any deviation, measure the lower end position of each upper roller 4 to check if the composed curve has any deviation.

[0042] Step 3: Measure the distance between the lower end of the upper roller 4 and the upper end of the lower roller 5 to check whether it meets the distance standard.

[0043] Step 4: Compare, compare the data measured at both ends of the upper roller 4 and the lower roller 5, and check whether the installation of both ends of the upper roller 4 and the lower roller 5 is consistent.
