[0028] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0029] The present invention provides a rail size detection and calibration device to solve the technical problem of reducing the calibration efficiency of the current rail handling. The rail size detection and calibration device comprises a base 1, a calibration frame 2, a turning mechanism 3 and a calibration rail 4, wherein:

[0030] The base 1 is used to stably support the rail to be inspected to ensure that it will not be displaced or shaken during use. The shape and size of the base 1 are customized according to the specifications of the rail in actual application to ensure that the base 1 is compatible with the rail and provides stable support.

[0031] The calibration frame 2 is installed on the base 1 and is used to provide a reference coordinate system for subsequent rail detection. Specifically, a plurality of marking points are set on the calibration frame 2 to ensure that the scanner can capture and identify. The calibration frame 2 has a verification area 11, and the verification area 11 is used to detect the rails to be inspected. The scanner will scan and collect data on the rails according to the preset program and path. The calibration frame 2 preliminarily locates the rails to reduce the possibility of the rails moving outside the calibration frame. At the same time, the calibration frame 3 can reduce the entry of other objects in the external environment into the verification area 11.

[0032] The flipping mechanism 3 is installed on the base 1 . The flipping mechanism 3 is located between the calibration frame 2 and the base 1 . A placement area 10 is provided between the flipping mechanism 3 and the base 1 .

[0033] The check rail 4 is installed on the flipping mechanism 3, and the flipping mechanism 3 is used to drive the check rail 4 to move between the check area 11 and the placement area 10. Specifically, the check rail 4 is placed in the placement area 10 in the initial state, and there are no other rails in the check area 11. When the rail needs to be checked, first, the flipping mechanism 3 is started to drive the check rail 4 to move from the placement area 10 to the check area 11. After the check rail 4 is placed in the check area 11, the scanner records the data of the check rail 4. After completing the data recording of the check rail 4, the flipping mechanism 3 is started again to move the check rail 4 from the check area 11 back to the placement area 10. At this time, the check area 11 is in an idle state again, ready to welcome the rail to be tested. The rail to be tested is placed in the check area 11, and the scanner is started again to record the data of the rail to be tested. The data can be compared with the previously recorded check rail 4 data to evaluate whether the size and shape of the rail to be tested meet the requirements.

[0034] Through the above structure, the present invention provides a rail size detection and calibration device. When the device is in the initial state, the check rail 4 is located in the placement area 10. When the size of the rail needs to be detected, the flipping mechanism 3 drives the check rail 4 to move from the placement area 10 to the verification area 11. The scanner used to detect the rail and record the data of the check rail 4, then the flipping mechanism 3 drives the check rail 4 to move from the verification area 11 to the placement area 10, and the rail to be detected is placed from one end of the calibration frame 2 into the verification area 11. The calibration frame 2 performs preliminary positioning of the rail to reduce the possibility of the rail moving outside the calibration frame, and the scanner then records the data of the rail. Therefore, the rail size detection and calibration device reduces the handling and positioning of the check rail 4 and improves the efficiency of rail verification by driving the check rail 4 to move between the verification area 11 and the placement area 10. The calibration frame performs preliminary positioning of the rail to facilitate the detection of the rail to be detected.

[0035] An optional implementation of this embodiment is as follows: the flipping mechanism 3 includes a driving member 31 and a clamping member 32, wherein the driving member 31 is installed on the base 1 to provide power for driving the verification rail 4 to move, and the clamping member 32 is rotatably installed on the base 1, and the clamping member 32 is connected to the driving rod by gear transmission, chain transmission or belt transmission to realize the transmission of power to drive the rotation of the clamping member 32. When the verification rail 4 needs to be flipped and moved, the driving rod is started, and the power is transmitted to the clamping member 32 through the transmission mechanism. The clamping member 32 starts to rotate under the drive of the power, thereby driving the verification rail 4 to move between the placement area 10 and the verification area 11.

[0036] An optional implementation of the present embodiment is as follows: it also includes a support rod 5, the support rod 5 is installed on the base 1, the calibration frame 2 is installed on the support rod 5, the support rod 5 is used to support the calibration frame 2 and the rail, the support rod 5 includes a first section and a second section, the clamping member 32 is installed on the second section, a placement space is formed between the second section and the base 1, and the driving member 31 is located between the first section and the base 1.

[0037] An optional implementation of the present embodiment is as follows: the calibration frame 2 includes a plurality of calibration rods 21, each calibration rod 21 is provided with a marking point, so that the scanner can establish a coordinate system according to the marking point, and the plurality of calibration rods 21 are installed on the support rod 5, the calibration rods 21 are parallel to the support rod 5, and the plurality of calibration rods 21 and the support rod 5 are arranged to form a verification area 11, and the rail to be inspected enters the verification area 11 from one end of the calibration rod 21. It is worth noting that the position of the calibration rod 21 should not affect the flipping of the verification rail 4.

[0038] An optional implementation of the present embodiment is as follows: the calibration frame 2 also includes a fixing ring 8, the fixing ring 8 is installed on the base 1, the calibration rod 21 is installed on the fixing ring 8, the fixing ring 8 is connected to the calibration rod 21, the fixing ring 8 is used to support and fix the calibration rod 21, the material and size of the fixing ring 8 need to ensure that it can bear the weight of the calibration rod 21 and maintain a stable shape during the detection process, the fixing ring 8 can ensure that the rail is always located in the calibration area after passing through the fixing ring 8, thereby reducing the deviation of the rail.

[0039] An optional implementation of the present embodiment is as follows: there are multiple fixing rings 8, and the multiple fixing rings 8 are distributed along the axial direction of the calibration rod 21. The multiple fixing rings 8 improve the stability of the calibration rod 21, making the calibration rod 21 more firm and reliable during the detection process, and improving the service life of the calibration frame 2. The number of fixing rings 8 is at least two, and there is at least one fixing ring 8 at both ends of the calibration rod 21, so as to better support the calibration rod 21. It is worth noting that when the position of the fixing ring 8 affects the flipping of the verification rail 4, an opening can be opened on the fixing ring 8 to allow the verification rail 4 to pass through.

[0040] An optional implementation of the present embodiment is as follows: it also includes a support roller 6, which is rotatably mounted on the base 1 and is located at one end of the calibration frame 2. Specifically, the axial direction of the support roller 6 is perpendicular to the support rod 5 to ensure that the rail can be stably placed on the support roller 6, and also enables the rail to move in a direction parallel to the support rod 5. The rail to be tested is placed on the support roller 6, and as the support roller 6 rotates, the rail will move in a direction parallel to the support rod 5. The rotation of the support roller 6 can be driven by a motor or other driving methods. By adding the support roller 6, before the detection begins, it is only necessary to place the rail to be tested on the support roller 6, and the rail will move through the support roller 6 and enter the verification area 11.

[0041] An optional implementation of the present embodiment is as follows: it also includes guide rollers 7, two guide rollers 7 are provided, the two guide rollers 7 are rotatably installed on the base 1, the two guide rollers 7 are perpendicular to the axial direction of the support rollers 6 and the rails, and a channel for passing the rails is formed between the two guide rollers 7. When the rails are placed on the support rollers 6 and move forward, both sides of the rails will abut against the guide rollers 7. The guide rollers 7 guide and correct the rails, thereby reducing the deviation or tilt of the rails due to external interference. At the same time, the rolling of the guide rollers 7 also reduces the resistance and wear of the rails during movement.

[0042] An optional implementation of this embodiment is as follows: support rollers 6 and guide rollers 7 are provided at both ends of the support rod 5, so that the rails can be sent into the inspection area 11 from a position close to the support rollers 6 at either end, and the rails after inspection are sent out of the inspection area 11 from the other end. The two-way entry and exit improves the inspection efficiency.

[0043] An optional implementation of this embodiment is as follows: it also includes a roller 9, which is rotatably installed on the support rod 5, and the axial direction of the roller 9 is perpendicular to the axial direction of the support rod 5. The roller 9 works together with the supporting roller 6 to jointly support and guide the movement of the rail in the verification area 11, thereby reducing the friction resistance and wear between the rail and the support rod 5.

[0044] In summary, when the rail size detection and calibration device 2 is in the initial state, there are no other rails in the verification area 11. When the rail needs to be verified, first, the driving member 31 drives the clamping member 32 to rotate, driving the verification rail 4 to move from the placement area 10 to the verification area 11. After the verification rail 4 is placed in the verification area 11, the scanner records the data of the verification rail 4. After completing the data recording of the verification rail 4, the driving member 31 drives the clamping member 32 to rotate again, and moves the verification rail 4 from the verification area 11 back to the placement area 10. At this time, the verification area 11 is in an idle state again. , place the rail to be inspected on the support roller 6, the support roller 6 rotates, and the rail to be inspected is moved from the end of the support rod 5 close to the first section to the verification area 11. The two sides of the rail are in contact with the guide rollers 7, and the guide rollers 7 guide and correct the rail, which reduces the deviation or tilt of the rail due to external interference. At the same time, the rolling of the guide rollers 7 also reduces the resistance and wear of the rail during movement. After the rail enters the verification area 11, the scanner is started again to record the data of the rail to be inspected. Finally, the support roller 6 close to the second section rotates to move the rail out of the verification area 11. Therefore, the rail size detection and calibration device 2 reduces the handling and positioning of the verification rail 4 and improves the verification efficiency of the rail by driving the verification rail 4 to move between the verification area 11 and the placement area 10.
