Description

Technical Field

[0001] The present invention relates to the field of rail transportation technology, and in particular to a multi-dimensional rail automatic alignment device. Background Art

[0002] Rail joints are a crucial component of railway turnouts. Factory-made rail joints are made from rails, insulation material, bolts, and other components through a heating, pressurizing, and tightening process. To ensure optimal performance, joint straightness must be controlled. Therefore, prior to joint fabrication, operators must align the two rail ends to ensure that the joint meets standard straightness requirements.

[0003] At present, the alignment of the rail joint ends is mainly done manually. The operator uses a manual wrench to adjust the lifting rollers on both sides of the workstation to adjust the height of the rail. If the rail joint is still low after the lifting roller is adjusted to the highest point, the operator needs to raise the far end of the rail to lower the height of the rail joint and achieve smooth alignment of the rail joint. The lateral position of the rail is adjusted by the threaded tightening mechanisms on both sides perpendicular to the length of the rail. The operator adjusts the lateral position of the rail by adjusting the different tightening distances of the screw. Repeated adjustments are performed to achieve lateral alignment of the rail. If the rail bottom is twisted, the rail bottom tightening screw is needed to adjust the twisted rail bottom. If the rail bottom is twisted to the right, the left rail bottom tightening mechanism is loosened and the right rail bottom tightening mechanism is continued to be tightened. The rail bottom will twist to the left, thereby achieving adjustment of the rail bottom twist. When adjusting the lateral position of the rails, generally only the rail head tightening mechanisms on both sides are used to adjust and align the rails. If the rail bottom is still twisted after the rail head is adjusted into place, the rail bottom tightening mechanisms on both sides are used to adjust the twisting of the rail bottom.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] See also Figure 1-13The present invention provides a multi-dimensional rail automatic alignment device, including a left position adjustment mechanism 1, a right position adjustment mechanism 2, a joint straightness detection mechanism 3, a remote movement adjustment mechanism 4 and an auxiliary automatic feedback adjustment system.

A detection storage rack 17 is fixedly provided on one side of the left supporting frame 11, and a detection protection plate 16 is fixedly provided on the outer side of the detection storage rack 17. The auxiliary automatic feedback adjustment system includes a PLC controller and control software. The control software can realize automatic control of each adjustment mechanism of the device. The joint straightness detection mechanism 3 transmits the detection data to the control system. The system analyzes the data and adjusts the rail position according to the straightness deviation. After the adjustment is completed, the straightness detection is performed again. This process is repeated until the joint straightness meets the relevant standard requirements.

[0032] The right position adjustment mechanism 2 includes a plate frame body 21 and a right support frame 22. Two hinge assemblies 25 are fixedly provided on one side of the top of the right support frame 22. A plate frame body 21 is provided between the two hinge assemblies 25. Two torsion frames 28 are fixedly provided on the other side of the top of the right support frame 22. A pin 210 is provided between the two torsion frames 28. Both ends of the pin 210 are provided with connecting plates 212. The tops of the two connecting plates 212 are fixedly connected to the side of the bottom end of the plate frame body 21 away from the hinge assembly 25. The right support frame 21 is fixedly provided with two torsion frames 28. A screw assembly 211 is fixedly installed in the middle of the top of the support frame 22, and a bottom plate frame 29 is provided at the top of the screw assembly 211.

Two upper rotating cylinders 23 are fixedly installed on one side of the top of the plate frame body 21, and the bottom ends of the inner sides of the two upper rotating cylinders 23 are provided with a lower top assembly 26. The adjustment mechanism mainly realizes the top and side compression of the rail, adjusts the lateral position of the rail and the torsion of the rail bottom, and is located on the upper side of the mechanism. The rotating oil cylinder 23 can realize the fixation of the height direction of the rail, and the side pressing oil cylinder side pressure assembly 27 realizes the horizontal fixation of the rail. It has the same design structure as the pressing oil cylinder of the left position adjustment mechanism 1. The side pressure assembly 27 is driven by the motor to move laterally through the adjusting push block opposite to the oil cylinder. The lateral position of the rail is adjusted by cooperating with the side pressure assembly 27, and the two adjusting push blocks can be controlled separately. A rail bottom torsion mechanism is designed under the lateral adjustment workbench. One side of the torsion mechanism is a hinge structure, and the other side is driven by a motor. The motor drives the screw rod and then drives the base plate connected to the screw rod to achieve horizontal lateral movement. The connecting plate with the inclined track mechanically connected to the base plate achieves synchronous horizontal lateral movement. The pin shaft 210 located in the inclined track will move up and down due to the horizontal lateral movement of the inclined track. The pin shaft 210 is mechanically connected to the upper adjusting device through the connecting plate 212. The hinge structure on one side cooperates with the up and down movement of the other side, thereby driving the entire upper adjusting device to deflect, thereby achieving the adjustment of the torsion of the rail bottom.

[0033] The joint straightness detection mechanism 3 includes four support frames 31 and a connecting beam 32. The four corners of the bottom end of the connecting beam 32 are fixedly provided with support frames 31, and the middle part of the bottom end of the connecting beam 32 is fixedly provided with a detection frame 33. Two rail bottom detection components 34, two rail head detection components 35 and a rail surface detection component 36 are fixedly installed on one side of the detection frame 33. The mechanism can detect the straightness of the center line of the top surface of the rail, the side surface of the rail head and the bottom of the rail. The measuring stroke is one meter. The infrared position sensor is used to detect the relative distance at different positions of the joint. By comparing the relative distance, the straightness deviation of the rail is judged, and then the position of the rail is adjusted. In order to meet the straightness detection requirements of rails of different specifications and sizes, the rail head side detection mechanism can move up and down, and the rail bottom detection structure can move laterally to expand the application range of the detection mechanism. The support frame 31 is connected to the support base installed on the ground. In order to facilitate the movement of the detection mechanism, a simple mechanical arm and a storage device are installed on the side of the left adjustment mechanism. The mechanical arm assists the up and down and rotation movement of the detection mechanism, thereby better reducing the labor intensity of the workers and protecting the detection mechanism at the same time.

[0034] The remote movable adjustment mechanism 4 includes a main frame 41 and a lifting roller assembly 43. Both sides of the top of the main frame 41 are slidably connected with directional slides 44. A lifting roller assembly 43 is fixedly arranged between the two directional slides 44. A cylinder 42 is fixedly installed in the middle of the main frame 41. The telescopic end of the cylinder 42 is fixedly connected to the middle of the bottom end of the lifting roller assembly 43. The four corners of the bottom end of the main frame 41 are fixedly installed with universal wheels 45. This mechanism is a movable roller bracket, and the bracket position can be moved to different positions as needed. The lifting roller assembly 43 on the upper part of the bracket is a pneumatically driven lifting roller. This mechanism can assist in adjusting the height position of the rail joint end. If the working roller table sinks and the position of the rail joint end is too high, exceeding the adjustment range of the lifting push block, the remote adjustment roller can be raised to reduce the height of the rail joint end and smoothly align the rail joint end. The movable structural design can meet the adjustment requirements of rails of different lengths and is more flexible to use.

[0035] When the embodiment of the present application is in use: the two rails to be glued are placed at the gluing station, the glued end faces are fitted together, and the positions of the left and right sides are respectively pressed by the left position adjustment mechanism 1 and the right position adjustment mechanism 2 to determine the initial position of the rails, and then the joint straightness detection mechanism 3 is placed above the rails, and the position facing the inner side of the detection frame 33 is to ensure the accuracy of the position of the detection component, and the automatic alignment system is started. The system automatically starts to perform the alignment work of the glued end of the rails. The detection component is an infrared position sensor. The infrared position sensor first detects the straightness of the rail bottom, and the data is transmitted to the control system. The control system judges the straightness of the rails based on the rail bottom detection data on both sides. Whether there is skew at the bottom, if the deviation values of the rail bottom detection data on both sides of the joint are different, and the deviation values on both sides of the rail bottom are absolute values, including positive and negative signs, then there is skew at the rail bottom. Taking the fixed side of the rail bottom as the reference, the positive deviation indicates that the rail bottom is bulging on the skewed side according to the absolute positive and negative deviation values of the skewed side of the rail bottom, and the rail bottom is skewed from the negative deviation side to the positive deviation side of the rail bottom. The specific correspondence between the deviation value and the skew value is obtained by the control system through continuous data statistical analysis, and is related to the position of the sensor relative to the rail bottom. After adjustment, the sensor will detect the straightness of the rail bottom again. If there is still skew at the rail bottom, the skew correction of the rail will continue until the relative skew of the rail bottom on both sides of the joint is completely eliminated; then the detection The mechanism detects the straightness of the side of the rail head, and the control system determines whether there is a deviation in the lateral position of the rail based on the deviation value of the detection data on both sides of the joint, and takes the side of the rail head of the transverse fixed side rail as the standard. If the deviation value of the transverse adjustable side rail is a fixed value within the measurement range, the two transverse adjustment push blocks are used to move the rail as a whole to the negative deviation, that is, the transverse adjustable side rail is moved to the recessed side relative to the transverse fixed side rail. If the side deviation value of the transverse adjustable side rail is not a fixed value and the deviation value changes from large to small or from small to large within the detection range, the advancement distance of the front and rear two transverse adjustment push blocks are adjusted respectively according to the change in the deviation value to adjust the lateral position of the rail. After the adjustment, the sensor detects the side straightness of the rail head again. Linearity: If there is still a deviation in the straightness of the side of the rail head, the lateral position of the rail will continue to be adjusted until the straightness of the side of the rail head meets the requirements; then the detection mechanism will detect the straightness of the rail top surface, and the control system will judge whether there is a deviation in the height position of the rail based on the deviation value of the detection data on both sides of the joint. The top surface of the rail on the height-fixed side will be used as the standard. If the deviation value within the measurement range of the rail on the height-adjustable side exceeds the adjustment range of the push block, the remote lifting mechanism will be used to adjust the height of the rail joint. If the joint position is low, the remote lifting mechanism will be lowered; if the joint position is high, the remote lifting mechanism will be raised. When the height deviation value is within the adjustment range of the push block, the push block will adjust the rail height.If the deviation value within the measuring range of the height-adjustable side rail is a constant, the two height-adjusting push blocks are used to move the rail as a whole toward the negative deviation, that is, relative to the height-fixed side rail, the height-adjustable side rail is moved to the lower side. If the deviation value of the top surface of the height-adjustable side rail is not a constant value, and the deviation value within the detection range changes from large to small or from small to large, then according to the change in the deviation value, the pushing distance of the front and rear two height-adjusting push blocks is adjusted respectively to adjust the height position of the rail. After the adjustment, the sensor is used to detect the straightness of the rail top surface again. If there is still a deviation in the straightness of the rail top surface, continue to adjust The height of the rail is adjusted until the straightness of the rail top surface meets the requirements; after the center line of the rail top surface, the side of the rail head and the rail bottom are all aligned, the sensor once again performs a final unified check on the straightness of the three positions to ensure that all straightness meets the requirements. The system automatically prompts that the rail alignment is complete. After the straightness of the center line of the rail top surface is qualified, the control system continues to adjust the straightness of the rail head side according to the same process. The right side lateral push block adjustment mechanism cooperates with the tightening cylinder to adjust the lateral position of the rail until the straightness of the rail head side meets the standard requirements. After the straightness of the rail head side is qualified, the control system finally adjusts the straightness of the rail bottom. The infrared position sensor detects the relative position of the rail bottom. If there is any twisting of the rail bottom, the control system controls the right rotation mechanism to twist the rail bottom until the straightness of the rail bottom meets the requirements. After the straightness of the center line of the rail top surface, the side of the rail head and the rail bottom are all aligned, the sensor once again performs a final unified check on the straightness of the three positions to ensure that all straightness meets the requirements. The system automatically prompts that the rail alignment is complete.
