[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] Reference Figure 1 and Figure 4 , the rail locking device and method provided by the present invention are now described.

[0039] Reference Figure 1 In the first aspect, the rail locking device provided in this embodiment includes a base 1, a support member 2, a pressure detection component 3 and a correction component 4 arranged on the support member 2.

[0040] The base 1 is fixed on the ground and abuts against the bottom of the rail. The support member 2 is fixedly connected to the base 1. At least one pressure detection component 3 is provided, which is fixedly connected to the support member 2 and abuts against the top of the rail, and is used to detect the deformation of the top of the rail. At least one correction component 4 is provided, which is arranged on the support member 2 and abuts against the top of the rail. The correction component 4 includes: a fixed member 41, a telescopic member 42 and a driving member 43. The fixed member 41 is fixedly connected to the support member 2. The telescopic member 42 is arranged on the fixed member 41. The driving member 43 is arranged on the fixed member 41 or the support member 2; the driving member 43 is connected to the telescopic member 42, and is used to drive the telescopic member 42 to extend or retract, so that the telescopic member 42 abuts against the side of the rail and corrects the deformation of the rail.

[0041] Reference Figure 2 In a possible implementation, a mounting seat 44 is provided on the fixing member 41, the telescopic member 42 is threadedly matched with the mounting seat 44, the driving member 43 is a motor, the driving member 43 is slidably connected to the fixing member 41, and the power output shaft of the driving member 43 is connected to the telescopic member 42.

[0042] In a possible implementation, the correction component 4 further includes a sliding seat 45 slidably connected to the fixing member 41 , and the driving member 43 is fixedly connected to the sliding seat 45 .

[0043] When the motor is working, the power output shaft of the motor drives the telescopic member 42 to rotate. Under the action of the thread, the telescopic member 42 extends out and abuts against the side of the top of the rail. This process drives the motor and the sliding seat 45 to slide together. After the telescopic member 42 abuts against the side of the rail, the motor continues to work, and the telescopic member 42 applies pressure to the rail, thereby correcting the deformation of the top of the rail. The head of the telescopic member 42 is provided with a contact head, and the contact head and the telescopic member 42 are rotated and matched. After the contact head abuts against the side of the top of the rail, if the motor continues to work and drives the telescopic member 42 to continue to apply pressure to the top of the rail, the contact head will not be relatively displaced with the side of the rail, thereby preventing the telescopic member 42 from damaging the side of the rail.

[0044] Reference Figure 3 In a possible implementation, the telescopic member 42 is slidably matched with the fixed member 41, the driving member 43 is a cylinder, the base 1 of the driving member 43 is fixedly connected to the fixed member 41 or the support member 2, and the piston rod of the driving member 43 is fixedly connected to the telescopic member 42.

[0045] In a possible implementation, the telescopic member 42 is slidably matched with the fixed member 41 , the driving member 43 is a hydraulic cylinder, the base 1 of the driving member 43 is fixedly connected to the fixed member 41 or the support member 2 , and the piston rod of the driving member 43 is fixedly connected to the telescopic member 42 .

[0046] In a possible implementation, it also includes: a pressure sensor arranged at the head of the pressure detection component 3 and a control module connected to the pressure sensor in communication; the control module is connected to the drive member 43 in communication; the pressure sensor sends the detected pressure information to the control module, the control module determines whether the rail is deformed according to the pressure information, and the control module controls whether the drive member 43 works according to the judgment result.

[0047] The beneficial effect of the rail locking device provided by the present invention is that compared with the prior art, the rail locking device of the present invention uses a base 1 to abut the bottom of the rail to fix the position of the bottom of the rail, and a pressure detection component 3 abuts the bottom of the rail. If the top of the rail is not deformed, the pressure detection component 3 cannot detect the pressure. If the top of the rail is deformed, the pressure detection component 3 detects the pressure, and the driving member 43 drives the telescopic member 42 to abut the top of the rail, thereby correcting the deformation of the top of the rail.

[0048] In a preferred embodiment, two pressure detection components 3 and two correction components 4 are provided, wherein two pressure detection components 3 and two correction components 4 are respectively provided at the top and the middle of the rail. The pressure detection component 3 provided at the top of the rail is used to detect the deformation of the top of the rail, and the correction component 4 provided at the top of the rail is used to correct the deformation of the top of the rail. The pressure detection component 3 provided at the middle position of the rail is used to detect the deformation of the middle position of the rail, and the correction component 4 provided at the middle position of the rail is used to correct the deformation of the middle position of the rail.

[0049] The straight section of the rail will not be deformed, and the head of the pressure detection component 3 just abuts against the side of the rail, but the rail will not apply pressure to the pressure detection component 3, and the pressure detection component 3 will not detect pressure information. The top and middle of the curved section of the rail will be deformed, and the deformation of the top will be greater than that of the middle. At this time, after the base 1 is fixed, the head of the pressure detection component 3 abuts against the side of the rail, and the rail applies pressure to the pressure detection component 3 due to deformation.

[0050] After the pressure detection component 3 detects the pressure, it transmits the pressure information to the control module. The control module determines the degree of deformation of the rail based on the pressure information. The control module compares the pressure information with the pressure threshold. If the pressure information is higher than the pressure threshold, the deformation of the rail is determined. At this time, the difference between the pressure information and the pressure threshold is calculated, and the difference is compared with the difference threshold. If the pressure information exceeds the pressure threshold, the drive member 43 is controlled to work so that the telescopic member 42 abuts against the side of the rail to provide support for the rail, thereby correcting the deformation of the rail. If the difference exceeds the difference threshold, it means that the deformation of the rail is large. At this time, the control module controls the drive member 43 to drive the telescopic member 42 to support the rail, so that the side of the rail is out of contact with the head of the pressure detection component 3, thereby correcting the deformation of the rail and compensating for the rebound of the rail after the rail locking device is revoked.

[0051] If the difference does not exceed the difference threshold, it means that the deformation of the rail is not large. The control module controls the driving member 43 to drive the telescopic member 42 to abut against the side of the rail and apply pressure to the rail until the pressure information detected by the pressure detection component 3 returns to zero. The driving member 43 controls the telescopic member 42 to maintain the current position.

[0052] Reference Figure 4 In a second aspect, a rail locking method is provided, which is applied to the rail locking device of the first aspect, and comprises the following steps:

[0053] S1. Fix the base 1 to the bottom of the rail;

[0054] S2. Obtaining pressure information through the pressure detection component 3, and determining whether the top of the rail is deformed according to the pressure information;

[0055] S3. Control the driving member 43 to see whether it is working according to the judgment result; if the top of the rail is deformed, control the driving member 43 to drive the telescopic member 42 to correct the top of the rail.

[0056] In a possible implementation, pressure information is obtained through a pressure component, and whether the top of the rail is deformed is determined according to the pressure information, including:

[0057] The pressure information is compared with the pressure threshold. If the pressure information is lower than the pressure threshold, it is determined that the top of the rail has not been deformed; if the pressure information is not lower than the pressure threshold, it is determined that the top of the rail has been deformed.

[0058] In a possible implementation, controlling whether the driving member 43 works according to the judgment result includes:

[0059] If it is determined that the top of the rail is deformed, the drive member 43 is controlled to operate; if it is determined that the top of the rail is not deformed, the drive member 43 is controlled not to operate.

[0060] In a possible implementation, the method further includes:

[0061] During the operation of the driving member 43 , the pressure information is obtained in real time according to the pressure detection component 3 , and it is determined whether the rail is corrected according to the real-time pressure information. If the correction is completed, the driving member 43 is controlled to maintain the position of the telescopic member 42 .

[0062] In a preferred embodiment, two pressure detection components 3 and two correction components 4 are provided, wherein two pressure detection components 3 and two correction components 4 are respectively provided at the top and the middle of the rail. The pressure detection component 3 provided at the top of the rail is used to detect the deformation of the top of the rail, and the correction component 4 provided at the top of the rail is used to correct the deformation of the top of the rail. The pressure detection component 3 provided at the middle position of the rail is used to detect the deformation of the middle position of the rail, and the correction component 4 provided at the middle position of the rail is used to correct the deformation of the middle position of the rail.

[0063] The straight section of the rail will not be deformed, and the head of the pressure detection component 3 just abuts against the side of the rail, but the rail will not apply pressure to the pressure detection component 3, and the pressure detection component 3 will not detect pressure information. The top and middle of the curved section of the rail will be deformed, and the deformation of the top will be greater than that of the middle. At this time, after the base 1 is fixed, the head of the pressure detection component 3 abuts against the side of the rail, and the rail applies pressure to the pressure detection component 3 due to deformation.

[0064] After the pressure detection component 3 detects the pressure, it transmits the pressure information to the control module. The control module determines the degree of deformation of the rail based on the pressure information. The control module compares the pressure information with the pressure threshold. If the pressure information is higher than the pressure threshold, the deformation of the rail is determined. At this time, the difference between the pressure information and the pressure threshold is calculated, and the difference is compared with the difference threshold. If the pressure information exceeds the pressure threshold, the drive member 43 is controlled to work so that the telescopic member 42 abuts against the side of the rail to provide support for the rail, thereby correcting the deformation of the rail. If the difference exceeds the difference threshold, it means that the deformation of the rail is large. At this time, the control module controls the drive member 43 to drive the telescopic member 42 to support the rail, so that the side of the rail is out of contact with the head of the pressure detection component 3, thereby correcting the deformation of the rail and compensating for the rebound of the rail after the rail locking device is revoked.

[0065] If the difference does not exceed the difference threshold, it means that the deformation of the rail is not large. The control module controls the driving member 43 to drive the telescopic member 42 to abut against the side of the rail and apply pressure to the rail until the pressure information detected by the pressure detection component 3 returns to zero. The driving member 43 controls the telescopic member 42 to maintain the current position.
