[0073] The bridging mechanism 12 - 1 has at least two bridging longitudinal pipes 121 , which are respectively connected to the liquid inlet pipe 12 and the liquid outlet pipe 11 .

[0074] The connection positions of the two bridging longitudinal tubes 121 and the support plate 13 are spaced apart to ensure the uniformity and stability of the liquid flow.

[0075] specific:

[0076] In the present invention, the hydraulic test unit 101 includes a support mechanism on which a pipeline mechanism is arranged. The present invention facilitates the support and placement of the continuous casting roller assembly 3 to be tested in subsequent use through the arrangement of the support mechanism, and facilitates the arrangement and placement of the continuous casting roller assembly 3 during testing.

[0077] The setting of the support mechanism facilitates the support and placement of the continuous casting roller assembly 3 to be tested, and the setting of the pipeline mechanism facilitates the subsequent flow of water on the support assembly, which can then flow into the water channels of each bearing seat 34; thereby realizing the water pressure and water flow detection of the continuous casting roller assembly 3 to be tested.

[0078] In the present invention, the support mechanism includes a support stand 21. The support stand 21 plays a role of raising the structure and also serves as a placement rack, which facilitates the arrangement and placement of subsequent pipeline mechanisms. At the same time, a support plate 13 is provided on the support stand 21; the support plate 13 plays a connecting role and can also well ensure the overall structural strength of the support mechanism. At the same time, the setting of the support plate 13 also facilitates the installation and fixation of the continuous casting roller assembly 3 to be tested during subsequent use.

[0079] In the present invention, the pipeline mechanism includes a liquid inlet pipeline 12 and a liquid outlet pipeline 11 arranged on the support frame 21; the liquid inlet pipeline 12 is used for supplying water to the bearing seat 34, and the liquid outlet pipeline 11 is used to receive the water discharged from the bearing seat 34 to realize the reflux of the water.

[0080] In addition, the bridging mechanism 12-1 in the present invention includes at least two bridging longitudinal tubes 121, one end of one of the bridging longitudinal tubes 121 is connected to the liquid inlet pipe 12, and the other end is connected to the support plate 13; one end of the other bridging longitudinal tube 121 is connected to the liquid outlet pipe 11, and the other end is connected to the support plate 13; the connection positions of the two bridging longitudinal tubes 121 and the support plate 13 are distributed at intervals; through such an arrangement, it is convenient for the liquid inlet pipe 12 to be connected to the corresponding bearing seat 34 through a bridging longitudinal tube 121 and the liquid outlet pipe 11 to be connected to the corresponding bearing seat 34 through a bridging longitudinal tube 121, thereby realizing the circulation in and out and use of water.

[0081] At the same time, in the present invention, the liquid inlet pipe 12 and the liquid outlet pipe 11 are connected with a bridging mechanism 12-1; in the present invention, the setting of the bridging mechanism 12-1 is mainly used to cooperate with the continuous casting roller assembly 3 to be tested, and each bridging mechanism 12-1 corresponds to a bearing seat 34. The setting of the bridging mechanism 12-1 is mainly to realize the mutual connection between the liquid inlet pipe 12 and the liquid outlet pipe 11 and the water channel of the continuous casting roller assembly 3 to be tested, and then realize the water entering the bearing seat 34 or discharging the water channel of the bearing seat 34.

[0082] In the present invention, the jump detection unit 102 is mainly used to realize the roller unit jump value detection.

[0083] The runout detection unit 102 can measure the runout value of the continuous casting roll assembly 3 .

[0084] The vibration detection dial indicator 6 is installed on the upper bracket 4. The driving structure drives the continuous casting roller assembly 3 to rotate. The dial indicator can measure the vibration of the roller in real time.

[0085] This design can detect the runout values of multiple points at the same time, improving detection efficiency and accuracy.

[0086] The upper bracket 4 is connected to the bottom bracket 2 and is used for mounting the detection unit.

[0087] The detection unit mainly includes a runout detection dial indicator 6: which is installed on the upper bracket 4 and is used to measure the runout value of the continuous casting roller assembly 3.

[0088] The driving structure is used to drive the continuous casting roller assembly 3 to be tested to rotate so as to detect the runout value.

[0089] The specific design of the driving structure is diverse, usually including components such as a motor and a gear transmission to achieve smooth rotation of the roller; it can also be achieved by combining a worm 10, a coupling and a worm 10 driving a motor. The specific selection can be made according to actual requirements.

[0090] Furthermore, in the present invention, the driving structure includes a ring gear 8 arranged on the continuous casting roller assembly 3 to be tested; the ring gear 8 is connected to a driving unit 71 for driving the ring gear 8 to rotate; the setting of the ring gear 8 is equivalent to arranging an external driving component on the continuous casting roller assembly 3 to be tested, which facilitates the rotation of the continuous casting roller assembly 3 to be tested during the runout value detection.

[0091] In the present invention, the gear ring 8 is installed on the roller unit of the continuous casting roller assembly 3 to be tested, and is used to cooperate with the driving structure to realize the rotation of the roller.

[0092] The gear ring 8 is composed of two semicircular arc-shaped single arc rings, which are relatively spliced into a complete gear ring 8: this split design is easy to install and disassemble, and can quickly fix the gear ring 8 on the roller, reducing assembly time and labor intensity.

[0093] The two single arc rings are connected by bolts to ensure that the gear ring 8 remains firm and stable during operation.

[0094] The ring gear 8 is connected to the driving unit 71 , and the power of the driving unit 71 drives the ring gear 8 to rotate, thereby realizing the rotation of the roller.

[0095] The rotation of the ring gear 8 enables the runout detection dial gauge 6 to measure the runout value of the roller in real time.

[0096] The drive unit 71 is mounted on the platform frame 1 or the bottom bracket 2 in a detachable connection manner, which is convenient for installation and maintenance.

[0097] The driving unit 71 generally includes a motor, a reducer and a transmission mechanism (such as a worm 10 transmission device), which can provide stable power output.

[0098] The driving unit 71 provides power to the ring gear 8, which drives the roller to rotate.

[0099] During the rotation process, the runout detection dial indicator 6 can measure the runout value of the roller in real time to ensure the accuracy of the detection.

[0100] Furthermore, in the present invention, the gear ring 8 includes two semicircular arc-shaped single arc rings, and the two single arc rings are relatively spliced into a complete gear ring 8; in the present invention, the gear ring 8 is equivalent to adopting a split design: such a design facilitates the installation and disassembly of the gear ring 8 on the continuous casting roller assembly 3.

[0101] The split design makes the installation and removal of the ring gear 8 more convenient and quick, reducing assembly time and labor intensity.

[0102] The appropriate gear ring 8 can be selected according to roller units of different sizes, thereby improving the versatility and flexibility of the equipment.

[0103] If a part of the gear ring 8 is damaged, the damaged single arc ring can be replaced separately, which reduces maintenance costs.

[0104] The two single arc rings are connected by bolts to ensure that the gear ring 8 remains firm and stable during operation.

[0105] In the present invention, the drive unit 71 is designed to be installed on the platform frame 1 or the bottom bracket 2 through a detachable connection; the detachable design makes the installation and disassembly of the drive unit 71 more convenient and quick, reducing maintenance time and labor intensity.

[0106] The position and angle of the driving unit 71 can be quickly replaced or adjusted according to different detection requirements.

[0107] If the drive unit 71 needs to be upgraded (such as replacing a higher-power motor), the replacement can be completed quickly, thereby improving the scalability of the device.

[0108] In the present invention, at least two detection units are arranged at intervals on each single roller 301; generally, the detection units are arranged at both ends of each single roller 301; this arrangement ensures the comprehensiveness and accuracy of the detection, can cover different positions of the roller, and avoid misjudgment caused by local detection.

[0109] The detection unit usually includes a runout detection dial gauge 6 for measuring the runout value of the roller.

[0110] The detection units arranged at intervals can cover multiple key positions of the roller, ensuring the comprehensiveness and reliability of the detection results.

[0111] By comparing data from multiple detection points, the roller runout can be evaluated more accurately and the detection accuracy can be improved.

[0112] The number and position of the detection units can be adjusted according to actual needs to adapt to different sizes and types of continuous casting roller assemblies 3.

[0113] In the present invention, the continuous casting roller assembly 3 is fixed to the corresponding support plate 13 through a bearing seat 34; the specific connection method can be bolt connection; this can ensure the stability of the placement of the continuous casting roller assembly 3 on the detection equipment during testing, and avoid the entire continuous casting roller assembly 3 from shifting during subsequent testing, thereby affecting the actual detection accuracy.

[0114] Furthermore, in the present invention, the detection units are connected to the upper bracket 4 via a connecting mechanism; the provision of the connecting mechanism facilitates the installation and arrangement of the various detection units on the upper bracket 4 .

[0115] Specifically, in the present invention, the connecting mechanism includes a support plate 5; by moving the support plate 5, the detection unit can be controlled to contact the continuous casting roller assembly 3 to be tested; the support plate 5 can be moved along the upper bracket 4, and by moving the support plate 5, the contact between the detection unit and the continuous casting roller assembly 3 to be tested can be controlled.

[0116] The design of the movable support plate 5 makes the adjustment of the detection unit more convenient, reducing the operation time and labor intensity; the detection unit contacts the roller unit when needed, and separates it when not needed, avoiding affecting the normal progress of other detection processes.

[0117] In order to better realize the above functions, the present invention requires that the support plate 5 is rotatably connected to the upper bracket 4 and can rotate around the axis of the bracket; the two can be connected by a rotating mechanism such as a hinge or a rotating shaft.

[0118] In subsequent use, by rotating the support plate 5, it can be determined whether the detection unit participates in the actual detection.

[0119] The rotating design allows the detection unit to be folded up when not in use, saving space and avoiding interference with other operations.

[0120] Furthermore, the detection device in the present invention further includes a movement detection unit 103 ; the setting of the transmission detection unit can realize the detection of the movement value of the single end roller 301 .

[0121] Specifically, the movement detection unit 103 in the present invention includes a movement dial indicator 1032 arranged on the single roller 301 in the continuous casting roller assembly 3 to be tested, an anvil 1031 arranged on the bearing unit close to the corresponding movement dial indicator 1032, and a movement dial indicator 1032 arranged on the single roller 301 in the continuous casting roller assembly 3 to be tested; when in use, the corresponding single roller 301 is pushed by external force, and the movement value of the single roller 301 is detected by the movement detection unit 103; in the present invention, the movement dial indicator 1032 is generally a magnetic dial indicator, and when used subsequently, it is magnetically fixed on the corresponding single roller 301, and is used to cooperate with the anvil 1031 to measure the movement value of the roller.

[0122] Anvil 1031: It is set on the bearing unit close to the movement dial indicator 1032 to provide a stable support point; the function of the anvil 1031 is to provide a reference surface to facilitate the subsequent detection of the movement value of the corresponding single roller 301 by the movement dial indicator 1032.

[0123] Ensure that the bearing unit remains stable when external force is applied to avoid affecting the measurement accuracy due to movement of the bearing unit.

[0124] When required to be used in the present invention, the corresponding single roller 301 is pushed by external force, and the movement value of the single roller 301 is detected by the movement detection unit 103; the external force push here generally requires the operator to push the corresponding single roller 301 with the crowbar 1303 to make it move in the axial direction; thereby realizing subsequent detection operations.

[0125] Furthermore, in the present invention, a water flow meter 15 and / or a gate valve 14 is provided on the bridge longitudinal pipe 121; the water flow meter 15 is installed on the bridge longitudinal pipe 121 for measuring the liquid flow through the pipe in real time.

[0126] This feature is crucial for evaluating the fluid flow of the continuous casting roll assembly 3 during hydraulic testing.

[0127] The flow meter 15 can accurately measure the liquid flow rate to ensure the accuracy and reliability of the hydraulic test.

[0128] The flow meter 15 can provide real-time feedback of flow data, so that the operator can adjust the test parameters in a timely manner; the data of the flow meter 15 can be recorded for subsequent analysis and quality control.

[0129] The gate valve 14 is installed on the bridge longitudinal pipe 121 to control the flow of liquid.

[0130] The gate valve 14 can be fully opened or closed, and the opening degree can also be adjusted to control the size of the liquid flow.

[0131] The gate valve 14 can flexibly control the flow of the liquid, making it convenient for the operator to adjust the flow rate as needed.

[0132] When it is necessary to stop the flow of liquid, the gate valve 14 can be quickly closed to prevent liquid leakage and ensure the safety of the testing process.

[0133] The design of the gate valve 14 facilitates maintenance and replacement, thereby improving the reliability and service life of the equipment.

[0134] Furthermore, in the present invention, at least two detection devices 1-1 are provided on the platform frame 1, and adjacent detection devices 1-1 are distributed at intervals; at least two detection devices 1-1 are installed on the platform frame 1, which means that the equipment can detect multiple continuous casting roller assemblies 3 simultaneously or sequentially.

[0135] Each detection device 1 - 1 includes a hydraulic test unit 101 , a jump detection unit 102 , a movement detection unit 103 , etc., and can independently complete a comprehensive detection of the continuous casting roller assembly 3 .

[0136] A certain distance is maintained between adjacent detection devices 1 - 1 ; this spacing distribution can avoid mutual interference between the detection devices 1 - 1 and ensure that each device can work independently and accurately during the detection process.

[0137] By providing a plurality of detection devices 1 - 1 , a plurality of continuous casting roller assemblies 3 can be detected simultaneously, which significantly improves the detection efficiency.

[0138] The idle time of testing equipment is reduced and the utilization rate of equipment is improved.

[0139] Each detection device 1-1 can work independently without interfering with each other.

[0140] This design allows the device to perform different types of tests simultaneously, improving the flexibility and diversity of testing.

[0141] The design of the interval distribution makes reasonable use of the space between the detection devices 1-1, which is convenient for operators to operate and maintain.

[0142] The platform framework 1 can be expanded with more detection devices 1 - 1 as needed to adapt to production needs of different scales.

[0143] A method for detecting a continuous casting roller assembly, comprising the following steps:

[0144] Step 1: Determine the continuous casting roller assembly 3 to be tested, and determine the corresponding testing equipment based on the continuous casting roller assembly 3 to be tested;

[0145] It is required to pre-connect the gear ring 8 in the testing equipment to the roller unit of the continuous casting roller assembly 3;

[0146] Step 2: Hoist the continuous casting roll assembly 3 to be tested onto the corresponding testing equipment and fasten the continuous casting roll assembly 3 to be tested to the support plate 13 of the testing device 1-1; at the same time, the gear ring 8 on the continuous casting roll assembly 3 to be tested must be connected to the drive unit 71 in the testing equipment after installation;

[0147] Step 3: Detecting the runout value of the roller unit in the continuous casting roller assembly 3 to be tested by the runout detection unit 102;

[0148] The movement detection unit 103 is used to detect the movement value of the single rollers 301 at both ends of the roller unit;

[0149] The hydraulic testing unit 101 is used to detect the water pressure and water flow of the continuous casting roller to be tested;

[0150] Then record each test data separately;

[0151] Step 4: After step 3 is completed, the inspection of a set of continuous casting roller assemblies 3 is completed. If repeated or new continuous casting roller assemblies 3 need to be inspected, the above steps 1-3 can be repeated.

[0152] Based on the above-mentioned operation mode, the present invention can realize the corresponding detection operation of the continuous casting roller assembly 3.

[0153] The specific detection method for continuous casting roller assembly includes the following steps:

[0154] Step 1: Determine the continuous casting roller assembly 3 to be tested and the testing equipment;

[0155] Select appropriate testing equipment to ensure the accuracy and reliability of the test.

[0156] Determine the continuous casting roll assembly 3 to be tested, including its size, type and testing requirements.

[0157] According to the characteristics of the continuous casting roller assembly 3 to be tested, the corresponding testing equipment is selected.

[0158] The gear ring 8 in the detection device is pre-connected to the roller unit of the continuous casting roller assembly 3 .

[0159] This step ensures that the ring gear 8 and the drive unit 71 can be smoothly connected during the hoisting and installation process, reducing assembly time and labor intensity.

[0160] Step 2: Hoisting and fastening;

[0161] The continuous casting roller assembly 3 to be tested is mounted on the testing equipment to ensure that it remains stable during the testing process.

[0162] The continuous casting roller assembly 3 to be tested is hoisted onto the testing equipment using a hoisting device.

[0163] The continuous casting roller assembly 3 is fastened to the support plate 13 of the detection device 1 - 1 to ensure that it does not move during the detection process.

[0164] After installation, ensure that the gear ring 8 on the continuous casting roll assembly 3 to be tested is connected to the drive unit 71 in the testing equipment.

[0165] This step ensures that the driving unit 71 can normally drive the ring gear 8 to rotate and realize the vibration detection function.

[0166] Step 3: Conduct various tests;

[0167] By testing each unit of the equipment, a comprehensive test of the continuous casting roller assembly 3 is completed.

[0168] Jump value detection:

[0169] The driving unit 71 is started to drive the ring gear 8 and the roller to rotate.

[0170] The runout value of the roller unit is measured by a runout detection unit 102 (such as a runout dial gauge).

[0171] Record the beat value data.

[0172] Fluctuation value detection:

[0173] A movement dial indicator 1032 is installed on the corresponding single roller 301 of the roller unit.

[0174] The single roller 301 is pushed by external force and its movement value is measured.

[0175] Record the fluctuation value data.

[0176] Water pressure and water flow detection:

[0177] Open the gate valves 14 of the liquid inlet pipe 12 and the liquid outlet pipe 11 of the hydraulic test unit 101 .

[0178] Start the pressure test water pump and perform water pressure testing on the continuous casting roller assembly 3 to ensure that there is no leakage under the test pressure.

[0179] At the same time, the water flow rate is measured by the water flow meter 15 and the flow data is recorded.

[0180] Data Records:

[0181] The data of runout value, oscillation value, water pressure and water flow are recorded separately for subsequent analysis and quality control.

[0182] Step 4: Repeat the test;

[0183] If a new continuous casting roll assembly 3 needs to be inspected, repeat the above steps to ensure that each assembly is fully inspected.

[0184] After completing the inspection of a set of continuous casting roller assemblies 3, a new inspection is performed as needed.

[0185] Repeat steps 1-3 to test the new continuous casting roller assembly 3.

[0186] Ensure that each component undergoes the same testing process to ensure consistency and reliability of test results.

[0187] Advantages of the above detection methods

[0188] Through the integrated testing equipment, the detection of the runout value, the oscillation value, the water pressure and the water flow can be completed simultaneously, ensuring a comprehensive quality assessment of the continuous casting roller assembly 3.

[0189] By pre-connecting the ring gear 8 and the drive unit 71 , assembly time and labor intensity are reduced, and detection efficiency is improved.

[0190] Data recording and analysis:

[0191] The data recorded during the testing process can be used for subsequent analysis and quality control to facilitate the identification of potential problems and make improvements.

[0192] Through standardized testing steps, it is ensured that each continuous casting roller assembly 3 undergoes the same testing process, thereby ensuring the consistency and reliability of the test results.

[0193] The detection equipment can be adjusted according to different sizes and types of continuous casting roller assemblies 3 to meet various detection requirements.

[0194] This detection method is particularly suitable for the production, maintenance and quality inspection of the continuous casting roller assembly 3.

[0195] Through integrated testing equipment and standardized testing procedures, various performance tests of the continuous casting roller assembly 3 can be completed quickly and accurately to ensure its reliability and stability on the production line. This method not only improves testing efficiency but also reduces the labor intensity of testing personnel, and has important practical application value.

[0196] Example 1:

[0197] The detection equipment disclosed in the present invention includes a platform frame 1, on which at least one detection device 1-1 is provided; each detection device 1-1 includes a hydraulic test unit 101, a bounce detection unit 102 and a sway detection unit 103.

[0198] The continuous casting roller assembly 3 to be tested disclosed in the present invention mainly includes a roller unit and a bearing unit connected to the roller unit.

[0199] The bearing unit includes a bearing and a bearing seat 34 assembly; the roller unit includes three single rollers 301, namely a first roller 31, a second roller 32 and a third roller 33.

[0200] During actual detection, the detection value of the continuous casting roller assembly 3 includes a jump value detection.

[0201] In actual use, two run-out value measurement points 601 are arranged on each individual roller 301 , and the run-out value measurement points 601 of the three individual rollers 301 total six.

[0202] There are two drift value measurement points 602, which are distributed at both ends of the single rollers at both ends of the continuous casting roller assembly; generally, the drift value detection is mainly performed on the first roller 31 and the third roller 33.

[0203] In the present invention, the continuous casting roller assembly 3 has four bearing seat 34 assemblies. Water enters each bearing seat 34 through the water inlet and flows out through the water outlet, and the water flow rate is measured.

[0204] When the water outlet on the outlet pipe is closed, the pressure test pump continues to pressurize to the test pressure, and the water pressure of the bearing seat 34 is measured to ensure that there is no leakage.

[0205] The detection device disclosed in the present invention realizes the function of electrically driving the rollers of the continuous casting roller assembly 3 to rotate by using the driving structure in conjunction with the gear ring 8 .

[0206] Specifically, a gear ring 8 is installed on the outer circle of a single roller 301 in the continuous casting roller assembly 3. The structure of the gear ring 8 is that the entire gear ring 8 is cut into two halves, and square steel plates with holes are welded on both sides of the joint surface. It can be closed firmly by tightening with bolts.

[0207] In order to make the connection more secure, a rubber pad can be appropriately placed between the gear ring 8 and the roller to increase its firmness.

[0208] The driving structure mainly consists of a worm gear 10 installed under the ring gear 8. Its module is consistent with the ring gear 8 and can achieve the transmission function. The two ends of the worm gear 10 are supported by worm seats, and one end is connected to the drive motor 7 through a coupling 9.

[0209] When the driving motor 7 is turned on, the ring gear 8 can be driven by the worm 10, and the ring gear 8 rotates together with the roller group.

[0210] In order to detect the runout accuracy of the continuous casting roller assembly 3, an upper bracket 4 is set on the bottom bracket 2; a support plate 5 is installed on the upper bracket 4, and a dial indicator support plate 5 is installed on the support plate 5. The support plate 5 can rotate, and 6 detection dial indicators 6 are installed on it with a magnetic seat. The detection dial indicators 6 here are also magnetic dial indicators; they correspond to the detection positions of the three single rollers 301 respectively.

[0211] If measurement is required, the support plate 5 is turned to the upper position, and the runout accuracy of 6 detection positions of 3 rollers can be read simultaneously.

[0212] After the inspection is completed, the support plate 5 is flipped to the right and the continuous casting roller assembly 3 can be lifted out.

[0213] The hydraulic testing unit 101 described in the present invention includes a supporting mechanism arranged on the platform frame 1, and a pipeline mechanism is arranged on the supporting mechanism; the supporting mechanism includes a supporting stand 21; the supporting stand 21 is provided with a support plate 13 for fixing the bearing unit; the pipeline mechanism includes a liquid inlet pipe 12 and a liquid outlet pipe 11 arranged on the supporting stand 21; each of the support plates 13 is connected to the liquid inlet pipe 12 and the liquid outlet pipe 11 through a bridging mechanism 12-1; the bridging mechanism 12-1 includes at least two bridging longitudinal pipes 121, one end of one bridging longitudinal pipe 121 is connected to the liquid inlet pipe 12, and the other end is connected to the support plate 13; one end of the other bridging longitudinal pipe 121 is connected to the liquid outlet pipe 11, and the other end is connected to the support plate 13; the connection positions of the two bridging longitudinal pipes 121 and the support plate 13 are distributed at intervals; in the present invention, a plurality of support plates 13 can be arranged on the support stand 21, and the bearing seats 34 in the continuous casting roller assembly 3 to be tested are respectively connected to one support plate 13.

[0214] When the continuous casting roller assembly 3 is hoisted on the supporting mechanism, all the bolts at the bottom of the bearing seat 34 are tightened on the corresponding supporting plate 13, which can achieve the same scene as the production site and ensure the inspection quality.

[0215] In the present invention, a gate valve 14 is provided at the inlet and outlet water channels under each bearing seat 34 in the pipeline mechanism, and a flow meter 15 is provided on one side. Such a design can realize water pressure test and detect the water flow rate of each bearing seat 34, thereby avoiding malfunction caused by low water flow due to unbalanced water channels of each bearing seat 34.

[0216] When detecting the movement value of the single roller 301, because the middle three-piece single roller 301 and the middle two sets of bearing seats 34 are pressed into one assembly, and there is movement in the bearing seats 34 on both sides, the detection of the movement value can be carried out as shown in the figure, and the crowbar 1303 is pried at both ends of the continuous casting roller, and the movement value can be observed on both sides.

[0217] The detection steps and methods are as follows:

[0218] Install the two halves of the outer gear ring 8 assembly on the outer circle of the roller on the far right of the figure, and tighten the bolts at the connection;

[0219] Hoist the continuous casting roller assembly 3 onto the inspection platform and tighten all the bolts at the bottom of the bearing seat 34 (using power tools to install can improve efficiency);

[0220] Turn the dial indicator support plate 511 to the left and place it on the top of the continuous casting roller assembly 3, and adjust the values of the six runout detection dial indicators 6 to zero;

[0221] Turn on the worm 10 drive motor to drive the ring gear 8 and the roller to rotate simultaneously, read the runout detection values of the 6 dial indicators, and complete the runout accuracy test;

[0222] Turn off the power supply of the drive motor;

[0223] Anvils 1031 are placed on both ends of the continuous casting roller assembly 3, and a magnetic dial indicator is placed on the roller, and the dial indicator is adjusted to zero.

[0224] Insert the crowbar 1303 on one side to pry the roller, read the runout value on the dial indicator and record it;

[0225] Then pry the roller on the other side, read the runout value on the dial indicator, record it, and complete the roller runout value detection;

[0226] Close the outlet valves 14 of the four bearing seats 34, open the inlet valves 14, and start the pressure test pump. After reaching the test pressure, maintain the pressure until the test time according to the test requirements. If there is no leakage during the test, the water pressure test is completed;

[0227] Open the outlet gate valves 14 of the four bearing seats 34, open the inlet gate valves 14, start the pressure test water pump, read the readings of the water flow meters 15, record the values, and complete the water flow detection.

[0228] Collect various data and complete the detection.

[0229] The present invention is designed with a flow detection function, which fills the gap that the previous method could only detect water pressure test but not flow detection.

[0230] The present invention designs an automatic driving device for continuous casting rollers, which solves the shortcomings of the previous method of manually rotating the rollers, which is time-consuming and labor-intensive, and the difficulty in measuring dimensional accuracy.

[0231] In the past, when testing the runout value of the continuous casting roller assembly, only one dial indicator was used to test one point. Now, six dial indicators are set at six points on the three roller sections to test simultaneously. This can simultaneously test the runout value of each roller, greatly improving the inspection efficiency.

[0232] In the past, when testing the runout value of the continuous casting roller assembly, the dial indicator was magnetically attached to the fixed seat with a magnetic chuck. The dial indicator head was tilted at 45 degrees to the end face of the roller surface, which would cause a large measurement error.

[0233] The current method is to magnetically attach the dial indicator to the end face of the roller, and then place a magnetic chuck on the top surface of the bearing seat 34 on the end face, so that the measured movement value is more accurate.

[0234] The detection equipment completely restores the installation status of the continuous casting roller assembly 3 on the production line, including the installation of the bearing seat 34 and the water pressure status, which are consistent with the on-site situation, avoiding the need for rework of the continuous casting roller assembly 3 after it is put into production;

[0235] The testing equipment integrates the functions of precision inspection, water pressure test and flow detection, and has the functions of complete testing items and high testing efficiency.

[0236] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the scope of protection of the present invention.
