[0040] In this embodiment, the top measuring mechanism mainly includes a first screw rod 9, a first stepper motor 10, a first distance measuring device and a second distance measuring device. Both ends of the first screw rod 9 are rotatably connected to the top of the mounting frame 1, and one end of the first screw rod 9 close to the fixed rail is connected to the first stepper motor 10, that is, the first stepper motor 10 is installed at a position close to the fixed rail, and the weight of the first stepper motor 10 is carried by the fixed rail to improve the overall stability, and the first stepper motor 10 can drive the first screw rod 9 to rotate; both ends of the first screw rod 9 are threadedly connected with sliders 11, and the first distance measuring device and the second distance measuring device are respectively installed on the sliders 11 at both ends, the first distance measuring device is used to measure the distance from the upper surface of the fixed rail, and the second distance measuring device is used to measure the distance from the upper surface of the movable rail, and the thread directions of the two ends of the first screw rod 9 are opposite, and the first stepper motor 10 can simultaneously drive the first distance measuring device and the second distance measuring device to move in opposite directions.

[0042] In this embodiment, the first ranging device, the second ranging device, the third ranging device and the fourth ranging device are all laser rangefinders 6, and the number of each ranging device can be selected as needed; preferably, the first ranging device and the third ranging device are each provided with two groups, and the second ranging device and the fourth ranging device are each provided with one group.

[0043] In this embodiment, the upper end surface alignment and the inner working surface alignment of the rail to be adjusted both adopt the alignment scheme of three groups of laser rangefinders 6, that is, the three-point collinear scheme, to improve the measurement accuracy; this embodiment is specifically described by taking the top measurement mechanism as an example:

[0044] Three groups of laser rangefinders 6 are used to measure the rail deviation at the upper end of the rail to be adjusted. Among them, two groups of laser rangefinders 6 near the first stepper motor 10 move synchronously and rotate in the forward direction. Their measuring points are on the fixed rail. Another group of laser rangefinders 6 is on the movable rail and rotates in the reverse direction. During the adjustment of the rail spacing, sampling is performed at any time for data feedback.

[0045] Working principle of laser rangefinder 6: 1) Three groups of laser rangefinders 6 are installed on the mounting frame 1. After adjusting the positions of the three groups of laser rangefinders 6, the relative values ​​of the three groups of laser rangefinders 6 in the X-axis direction relative to the coordinate origin (the initial point is defined on the left) are A, A+L1, and 2A+L1+L2 respectively; 2) The three groups of laser rangefinders 6 emit lasers to the surface to be measured respectively, and the measurement values ​​H1 and H2 are obtained on the fixed rail side, and the measurement value H3 (solid line part) is obtained on the movable rail side. The dotted line part is the measurement value H4 after adjustment; 3) The difference H3-H4 is the value that needs to be adjusted for the movable rail.

[0046] (2) In this process, the data of the position adjustment mechanism is derived from the threshold between the laser ranging data and the standard value.

[0047] In this embodiment, it should be noted that other distance measuring devices may be selected as needed, such as a displacement sensor.

[0048] In this embodiment, the position adjustment mechanism mainly includes a power part and an execution part. The power part can provide power to the execution part, and the execution part can contact the movable rail to drive the movable rail to move vertically and in a direction perpendicular to the fixed rail.

[0049] Furthermore, the execution part mainly includes a side airbag 4 and a bottom airbag 3, wherein the side airbag 4 is used to fit the waist of the inner working surface of the movable rail, and the bottom airbag 3 is arranged at the bottom of the movable rail. The power part is an air pump, which is connected to the side airbag 4 and the bottom airbag 3 through a gas pipeline 13, and is used for inflating and deflating, and drives the movable rail to move through the deformation of the airbag. Among them, other execution parts can also be selected according to needs, such as using a cylinder or a hydraulic cylinder.

[0050] In this embodiment, the position adjustment mechanism also includes an adjustment pad 12, and the adjustment pad 12 is supported on the bottom of the bottom airbag 3; the position adjustment mechanism also includes a support rod 7, one end of the support rod 7 is connected to the side airbag 4, and the other end is in contact with the fixed track 14. After the side airbag 4 is inflated, the support rod 7 applies force to the fixed track (a track parallel to the track to be adjusted), and under the action of the reaction force, the side airbag 4 will move against the movable track; wherein, the support rod 7 is preferably a telescopic rod, and the appropriate length is adjusted by telescoping so that the side airbag 4 can contact the movable track and push it to move. Moreover, a lifting platform or a telescopic rod or other structures can also be set on the adjustment pad 12 to drive the displacement of the bottom airbag 3.

[0051] In this embodiment, a solenoid valve 2 is also provided on the gas pipeline 13. The solenoid valve 2 is connected to the control mechanism signal and is used to control the on and off of the gas pipeline 13. The solenoid valve 2 is fixed on the support rod 7 and is in a normally closed state, that is, the gas pipeline 13 is kept closed and the pressure is maintained.

[0052] In this embodiment, a signal indicator light is also included, which is connected to the control mechanism signal to indicate the working status; specifically, when the position adjustment mechanism needs to work, the indicator light emits a warning light and there is a sound prompt.

[0053] The working process of the rail position adjustment device in this embodiment is as follows:

[0054] Step 1, the operator takes the measuring mechanism out of the protection box, fixes the measuring mechanism on the fixed rail and the movable rail according to the construction requirements, starts the self-check, and waits until the equipment works normally; adjusts the position of the laser rangefinder 6 to ensure that two groups of laser rangefinders 6 are on the fixed rail and the other group is fixed on the movable rail, and connects the solenoid valve 2 with the corresponding numbered gas pipeline 13, air pump, and airbag.

[0055] Step 2, take the position adjustment mechanism out of the protection box, insert the height adjustment part from between the two parallel rails under the rail to be adjusted, and the vertical adjustment part is between the two parallel rails.

[0056] Step 3, connect the vertical adjustment parts to both sides of the rails, one side of which is a fixed rail 14 that does not need to be adjusted, and the other side is a rail to be adjusted that needs to be adjusted horizontally during construction.

[0057] Step 4: The device starts up for self-test, connects the measuring mechanism, and obtains a signal indicating that the measuring mechanism is in place.

[0058] Step 5, press the automatic execution switch, the measuring mechanism starts to measure the position deviation of the welding surface of the track to be adjusted, and the measuring mechanism sends the measurement data to the control mechanism. The control mechanism sends a signal according to the built-in algorithm. The signal drives the vertical and horizontal adjustment parts to work according to the following steps to adjust the position of the movable rail. (1) Adjust the horizontal position deviation of the movable rail. The laser rangefinder 6 sends a horizontal adjustment signal according to the measurement data. At this time, the horizontal adjustment signal indicator sends a signal and a buzzer alarm. The control mechanism receives the signal, and the corresponding solenoid valve 2 starts to work, and the side airbag 4 starts to inflate to adjust the movement of the movable rail. During the movement, the measurement mechanism measures the deviation data and makes a difference with the standard. When it meets the threshold, the control mechanism receives a signal, the solenoid valve 2 is powered off, and the horizontal position remains unchanged, thereby achieving horizontal adjustment in place; (2) The alignment method of the upper surface of the rail is consistent with the horizontal method.

[0059] Step 6. After the above steps are completed, the rail position adjustment device is powered off, the device is placed in a protective box, and the adjustment work can be completed.

[0060] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
