Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

As shown in fig. 2, a cartesian coordinate system is established defining an x-axis, a y-axis, and a z-axis, wherein the length direction of the track 90 is disposed along the y-axis.

Embodiments provide a track correction device that can be used for correction of a track 90 such as a rail, wherein the correction includes straightening and crown bending.

As shown in fig. 1 and 2, the track correction device includes a feeding unit 10, a correction unit 30, a first blanking unit 20, a second blanking unit 40, and a detection unit 50. Wherein, the feeding end member 10 is arranged near the input end of the correction unit 30 for feeding. The second discharging unit 40 is disposed near an output end of the correcting unit 30 for discharging. The first blanking unit 20 is disposed near the input end of the calibration unit 30 and is disposed in parallel with the feeding unit 10. The detecting unit 50 is disposed between the feeding unit 10 and the first discharging unit 20. The detection unit 50 is used for detecting the straightness of the rail 90, and includes an initial detection and a retest of the straightness of the rail 90.

During operation, the rail 90 may be placed on the loading unit 10 for loading. The detection unit 50 may perform an initial inspection on the straightness of the rail 90 to determine whether the straightness of each portion of the rail 90 is acceptable. When the straightness of each part of the rail 90 is qualified, the rail 90 can be directly discharged by the first discharging unit 20 without passing through the calibration unit 30. When the partial straightness on the rail 90 is not appropriate, the rail 90 may enter the calibration unit 30, and the calibration unit 30 straightens or bends the corresponding portion of the rail 90, so as to make the whole straightness of the rail 90 acceptable. After the correction is completed, the rail 90 is blanked by the second blanking unit 40. Therefore, the rail correcting device can separately process the qualified and unqualified rails 90, so that the qualified rails 90 are directly discharged through the first discharging unit 20, time consumption caused by passing through the correcting unit 30 is avoided, and the operation efficiency and the productivity can be improved.

As shown in fig. 1 and 2, the track calibration device further includes a control unit 70, and the feeding unit 10, the first blanking unit 20, the calibration unit 30, the second blanking unit 40 and the detection unit 50 are electrically connected to the control unit 70, so that the control unit 70 can control and coordinate the operations of the other units.

In an embodiment, the feeding unit 10 includes a first feeding end 10a and a first discharging end 10b, and the first discharging end 10b is disposed near the first discharging unit 20 and corresponds to an input end of the calibration unit 30.

As shown in fig. 2, 4 and 5, the feeding unit 10 includes a plurality of sets of first support assemblies 11. The first supporting components 11 of the multiple groups can be uniformly arranged along the length direction of the track 90 at intervals, the first supporting components 11 of the multiple groups are arranged in parallel, and the first supporting components 11 of the multiple groups can support each part of the track 90. In the embodiment, the structures of the plurality of sets of first supporting members 11 are the same, and an alternative description thereof will be given below.

The first support assembly 11 includes a post 111 and a bracket 112. The bracket 112 has a length extending from the first loading end 10a to the first unloading end 10b and perpendicular to the length direction of the rail 90. The support 111 is used to support a bracket 112, and the bracket 112 is used to support the rail 90.

Any one of the first supporting components 11 is provided with a first pushing component 12 and a first driving component 13. The first pusher assembly 12 is slidably mounted on the carriage 112. The first driving assembly 13 is connected to the first pushing assembly 12 to drive the first pushing assembly 12 to move along the length direction of the bracket 112. During loading, an operator may place the rail 90 on an end of the bracket 112 close to the first loading end 10a, and then the first pushing assembly 12 may be driven by the first driving assembly 13 to move, so as to push the rail 90 from the first loading end 10a to the first unloading end 10b, so as to implement loading.

The first pushing assembly 12 includes a sliding seat 121 and a shifting lever 122, and the sliding seat 121 is connected to the first driving assembly 13. One end of the shift lever 122 away from the first blanking end 10b is hinged to the sliding seat 121, and a torsion spring (not shown) is disposed between the shift lever 122 and the sliding seat 121. The end of the lever 122 away from the hinge can tilt relative to the sliding seat 121 under the action of the torsion spring, and the end of the lever 122 away from the hinge protrudes from the upper surface of the bracket 112, i.e. the surface of the bracket 112 away from the pillar 111. Thus, one end of rod 122 may contact rail 90 to push rail 90 to move, and one end of rod 122 contacting rail 90 is disposed as a flat surface.

The bracket 112 is provided with an installation groove 1121 inside, and an opening communicating with the outside is provided on a side of the installation groove 1121 away from the pillar 111. The first driving assembly 13 and the first pushing assembly 12 are installed in the installation slot 1121, and one end of the driving lever 122 can protrude from the upper surface of the bracket 112 through an opening of the installation slot 1121.

The first driving assembly 13 includes an eighth driving member (not shown), a first driving belt 132 and a first driving wheel 131. The eighth driving member is fixedly installed at one end of the bracket 112 near the first discharging end 10b, and two first driving wheels 131 are respectively installed at two ends of the bracket 112. Both first driving wheels 131 are rotatably mounted on the bracket 112, and specifically, the first driving wheels 131 can be rotatably mounted on the end of the bracket 112 through a rotating shaft 133. The eighth driving member can be connected to the first driving wheel 131 near the first discharging end 10b, and the first driving belt 132 is connected between the first driving wheels 131. The carriage 121 is fixedly connected to the first belt 132. Therefore, under the driving of the eighth driving element, the first driving belt 132 can be driven to move, so as to drive the first pushing assembly 12 to reciprocate, thereby realizing the pushing action and the resetting of the first pushing assembly 12. The first transmission belt 132 and the first transmission wheel 131 can be connected through meshing engagement of the meshing teeth, so that slippage between the first transmission belt 132 and the first transmission wheel 131 is avoided. In an embodiment, the eighth driving member may be a motor.

In other embodiments, the first transmission belt 132 and the first transmission wheel 131 can also be a combination of belt and pulley, and the anti-slip effect is achieved by friction.

Any one of the first supporting assemblies 11 is further provided with a first reset detecting element 14 for detecting the actions of the first pushing assembly 12, including pushing and resetting, so as to prepare for the next pushing. Specifically, the first reset detecting element 14 may be a plate-shaped structure, the first reset detecting element 14 is fixedly installed at one end of the bracket 112 close to the first feeding end 10a, and the first reset detecting element 14 is fixedly installed at one side of the opening of the installation groove 1121. When the shift lever 122 is in a natural state, an end of the shift lever 122 away from the hinge joint may protrude out of a plane where the first reset detecting element 14 is located, so that the shift lever 122 may touch the first reset detecting element 14 when passing through the first reset detecting element 14, thereby triggering the first reset detecting element 14 to generate a corresponding signal. A gap is provided between the bottom surface of the first reset detecting member 14 and the upper surface of the slider 121. When the shift lever 122 is turned and abutted against the end of the slide seat 121 close to the first loading end 10a, the gap is allowed to pass by the shift lever 122. In the embodiment, a wire box 141 for protecting the wire connected to the first reset detecting member 14 is fixedly provided at one side of the bracket 112.

When the rail 90 needs to be pushed, the first pushing assembly 12 is driven by the first driving assembly 13 to pass through the first resetting detector 14, the first resetting detector 14 abuts against the lower surface of the shift lever 122, and the shift lever 122 is turned over towards one end of the first feeding end 10a under the action of the first resetting detector 14. After the first pushing assembly 12 passes through the first reset detecting element 14, the driving lever 122 is turned over to the end close to the first discharging end 10b for resetting, and when the driving lever 122 contacts the rail 90, the front end surface of the driving lever 122 can be completely attached to the surface of the rail 90, so as to push the rail 90 to move.

When the first pushing assembly 12 is reset, the driving lever 122 can rotate towards the inner direction of the sliding seat 121 under the pressing action of the first reset detecting member 14 to be retracted into the sliding seat 121 so as to pass through the first reset detecting member 14. At the same time, the toggle lever 122 will trigger the first reset detecting element 14, indicating that the first pushing assembly 12 has moved to the end of the bracket 112 near the first loading end 10a, and the eighth driving element can be deactivated. In one embodiment, the first reset detecting element 14 may be a contact switch. It can be understood that, during the resetting process of the first pushing assembly 12, after the first resetting detecting element 14 is triggered, the control unit 70 may set a certain delay time when controlling the eighth driving element to stop, so that the shift lever 122 is completely separated from the first resetting detecting element 14, and the first resetting detecting element 14 and the shift lever 122 are prevented from being pressed against each other for a long time, so as to protect the first resetting detecting element 14 and the shift lever 122.

In other embodiments, the first reset detecting element 14 may also be a non-contact sensor, such as an infrared sensor, a hall sensor, or the like. It can be understood that, when the first reset detecting element 14 is a hall sensor, a corresponding magnetic element such as a magnet can be disposed on the first pushing assembly 12 to trigger the hall sensor.

In other embodiments, the shift lever 122 can also be tilted or retracted into the sliding seat 121 by a motor.

In an embodiment, the feeding unit 10 further includes a first moving assembly 15, and the first moving assembly 15 is configured to drive the plurality of sets of first supporting assemblies 11 to slide. Specifically, the first moving assembly 15 includes a first sliding plate 151, a first sliding rail 152, and a ninth driving member (not shown). The first sliding plate 151 is slidably mounted on the first sliding rail 152, and the first sliding rail 152 is fixedly disposed, in an embodiment, the first sliding rail 152 can be fixedly mounted on the ground. The first slide rail 152 extends in a direction perpendicular to the length direction of the rail 90. The column 111 of the first support assembly 11 may be fixedly mounted to the first sliding plate 151. The ninth driving element is used for driving the first sliding plate 151 to slide along the first sliding rail 152 so as to be close to or far away from the input end of the first discharging unit 20, and thus the first supporting assembly 11 can be driven to be close to or far away from the first discharging unit 20.

As shown in fig. 1 and 2, in the embodiment, the track correction apparatus further includes a transport unit 60 for transporting the track 90 to bring the track 90 into or out of the correction unit 30. Specifically, the transport direction of the transport unit 60 to the rail 90 is set along the length direction of the rail 90. Specifically, the transportation unit 60 includes a first transportation assembly 61 and a second transportation assembly 62, and the first transportation assembly 61 and the second transportation assembly 62 are provided with a plurality of sets. The plurality of sets of first transmission assemblies 61 are disposed corresponding to the input end of the calibration unit 30, and the first transmission assemblies 61 are disposed near the first feeding end 10a of the feeding unit 10. The plurality of groups of first transmission assemblies 61 are distributed at intervals along the length direction of the track 90, and the plurality of groups of first transmission assemblies 61 and the plurality of groups of first support assemblies 11 are arranged in a staggered manner.

During loading, the first moving assembly 15 can drive the first supporting assembly 11 to move toward the direction close to the first conveying assembly 61, so that the end of the first supporting assembly 11 close to the first unloading end 10b extends to the conveying path of the first conveying assembly 61. After the rail 90 is pushed to the first blanking end 10b, it can be received by the first transferring assembly 61 so that the first transferring assembly 61 can convey the rail 90.

As shown in fig. 3, the first conveying assembly 61 includes a sixth driving element 614 and a first conveying roller 615, and the sixth driving element 614 is used for driving the first conveying roller 615 to rotate. The axis of the first conveying roller 615 is disposed along the horizontal direction and perpendicular to the length direction of the rail 90. In one embodiment, the first transmission assembly 61 further includes a first supporting block 611, a floating plate 612, and a tenth driving member (not shown), and the sixth driving member 614 is fixedly mounted on the floating plate 612. The floating plate 612 is floatingly mounted to the first support block 611 by a tenth driving member. In use, the tenth driving member drives the floating plate 612 to move up and down, so that the first feeding roller 615 contacts with or moves away from the rail 90. When the first conveying roller 615 is lifted to contact the rail 90, the rail 90 can be separated from the first supporting assembly 11 so as to facilitate the first conveying assembly 61 to convey the rail 90. When the first conveyor roller 615 descends away from the track 90, the first conveyor roller 615 will no longer act on the track 90. In an embodiment, a fourth guide rod 613 is further connected between the first support block 611 and the floating plate 612, one end of the fourth guide rod 613 is fixedly connected to the floating plate 612, and the other end of the fourth guide rod 613 is telescopically mounted on the first support block 611, so that the lifting of the floating plate 612 can be guided, and the floating plate 612 is prevented from tilting when lifted. In some embodiments, the sixth drive element 614 may be implemented as an electric motor with an encoder and the tenth drive element may be implemented as a hydraulic cylinder.

In other embodiments, the sixth driving element 614 can also be a hydraulic cylinder coupled to a gear assembly and a clutch to rotate the first feeding roller 615. The tenth driving member may also be an electric push rod, an air cylinder, a motor, a lead screw, or the like to drive the floating plate 612 to ascend or descend.

As shown in fig. 2, in the embodiment, the detection unit 50 includes a carriage 51, a support table 52, and at least three sets of laser detectors (not shown). The support table 52 is connected to the input end of the calibration unit 30, and the support table 52 extends along the length direction of the track 90. The multiple sets of first transmission assemblies 61 at the input end of the calibration unit 30 are all mounted on the support platform 52, and the feeding unit 10 and the first discharging unit 20 are respectively disposed at two sides of the support platform 52. The sliding frame 51 is slidably mounted on the support base 52, a fourth slide rail 521 engaged with the sliding frame 51 is provided on the support base 52, and the fourth slide rail 521 is provided along the longitudinal direction of the support base 52, that is, the sliding frame 51 is movable along the longitudinal direction of the rail 90. The sliding frame 51 may be a door-shaped frame, and the width of the opening inside the sliding frame 51 is larger than the width of the first conveying assembly 61, i.e. the dimension of the first conveying assembly 61 along the x-axis direction, so that the sliding frame 51 can pass through the first conveying assembly 61 smoothly. At least three sets of laser detectors are provided on three inner side walls of the carriage 51. In this embodiment, three sets of laser detectors are provided, wherein one laser detector is disposed on the inner wall of the top of the sliding frame. The other two laser detectors are respectively arranged on the two inner walls of the side edge of the sliding frame 51 and are symmetrically arranged. At the time of detection, the carriage 51 is movable along the longitudinal direction of the rail 90, so that the straightness of each portion of the rail 90 can be detected in two dimensions, i.e., the z-axis direction and the x-axis direction, by the three sets of laser detectors. During the detection, the first moving assembly 15 can drive the first supporting assembly 11 to move away from the first transmission assembly 61, so as to prevent the first supporting assembly 11 from interfering with the movement of the sliding frame 51.

In other embodiments, the laser detectors may be arranged in four groups, five groups, six groups, etc.

It will be appreciated that a twelfth driving element (not shown) may be disposed inside the support table 52 for driving the sliding frame 51 to slide, and the twelfth driving element may be a motor. An output shaft of the twelfth driving member is connected with a lead screw, and a nut sleeve (not shown) and the like which are matched with the lead screw can be arranged on the sliding frame 51 to realize the thread matching connection. Meanwhile, the sliding frame 51 does not synchronously rotate along with the lead screw under the limiting action of the fourth sliding rail 521, so that the linear movement of the sliding frame 51 is realized.

In the embodiment, the initial position of the carriage 51 should be a position between the rail 90 and the calibration unit 30, that is, the initial position is located at the front end of the rail 90. During the detection, the end position of the sliding frame 51 should be located on the side of the rail 90 away from the calibration unit 30, and a certain distance is provided between the ends of the rail 90. Therefore, when the straightness of the rail 90 is detected by the laser detector, it is convenient to determine whether the detection is started and completed, and it is also convenient for the laser detector to obtain the corresponding position information so that the position information corresponds to the straightness. Meanwhile, the initial position information of the rail 90 can be accurately obtained, so that the moving distance of the rail 90 at each time can be conveniently controlled during subsequent operation. It is understood that the initial position of the carriage 51 is fixed, that is, the carriage 51 is reset to the initial position after each detection by the detecting unit 50.

As shown in fig. 1 and 2, the first discharging unit 20 includes a second feeding end 20a and a second discharging end 20b, and the second feeding end 20a is disposed adjacent to the first discharging end 10b of the feeding unit 10. The first blanking unit 20 includes a plurality of sets of second support assemblies 21, and the plurality of sets of second support assemblies 21 are arranged at intervals along the length direction of the rail 90. In some specific embodiments, the number of the second support assemblies 21 may be equal to the number of the first support assemblies 11, and the second support assemblies may be arranged in a one-to-one correspondence. The structure of the second support member 21 is the same as that of the first support member 11.

Meanwhile, any one of the second supporting assemblies 21 is also provided with a second pushing assembly 22, a second driving assembly 23 and a second reset detecting piece 24. The structure and installation manner of the second pushing assembly 22 may be the same as those of the first pushing assembly 12, the structure and installation manner of the second driving assembly 23 may be the same as those of the first driving assembly 13, and the structure of the second reset detecting element 24 may be the same as that of the first reset detecting element 14, which are not repeated herein. The second reset detecting element 24 is disposed at an end of the second supporting assembly 21 close to the second feeding end 20 a. The second driving assembly 23 can drive the second pushing assembly 22 to move so as to push the rail 90 to move, and the second reset detecting element 24 can detect the movement of the second pushing assembly 22.

In an embodiment, the first discharging unit 20 further includes a second moving assembly 25 for driving the plurality of sets of second supporting assemblies 21 to move, and specifically, the second supporting assemblies 21 can be close to or far from the charging unit 10. Accordingly, the structure and installation manner of the second moving assembly 25 can be the same as those of the first moving assembly 15, and will not be described herein again.

It can be understood that when the detecting unit 50 detects the linearity of the track 90, the second moving assembly 25 can move the second supporting assembly 21 away from the supporting platform 52, so that the sliding frame 51 is retracted by the second supporting assembly 21. When the straightness of the track 90 is qualified during the initial inspection, the second moving assembly 25 can drive the second supporting assembly 21 to move toward the direction close to the supporting platform 52, and the end of the second supporting assembly 21 close to the second feeding end 20a extends to the transmission path of the first transmission assembly 61. Subsequently, the first conveying roller 615 can be lowered to drop the rail 90 on the second supporting assembly 21, and then the rail 90 can be pushed to the second discharging end 20b by the second pushing assembly 22 for discharging.

Further, as shown in fig. 2, the correction unit 30 includes a first correction mechanism 31 and a second correction mechanism 32 which are provided in this order. The input end of the first correcting mechanism 31 is disposed close to the feeding unit 10, and the input end of the first correcting mechanism 31 is the input end of the correcting unit 30. The output end of the first correcting mechanism 31 is arranged close to the input end of the second correcting mechanism 32, the output end of the second correcting mechanism 32 is arranged close to the second blanking unit 40, and the output end of the second correcting mechanism 32 is the output end of the correcting unit 30.

The extending direction of the first sliding groove 3141a is arranged in the horizontal direction, and is perpendicular to the length direction of the rail 90, i.e., in the x-axis direction. In an embodiment, a side of the first pressing head 3143 close to the second pressing member 315 protrudes from a lower surface of the first mounting block 3141, that is, the first mounting block 3141 is close to a surface of the second pressing member 315.

The second pressing member 315 is supported on the side of the mounting plate 3161 close to the first pressing member 314. Therefore, the second pressing member 315 can not rotate along with the transmission rod 3162. When the fourth driving member 3164 drives the transmission rod 3162 to rotate, the second pressing member 315 can be driven to move along the length direction of the transmission rod 3162. In an embodiment, the fourth driving member 3164 may be a motor.

In the embodiment, three sets of pressing members 315 are also provided, which is equal to the number of pressing members 314. The three sets of second pressing members 315 may be uniformly spaced along the length of the mounting plate 3161. The three sets of second pressing elements 315 have the same structure, and an alternative description thereof is provided below.

Specifically, the second pressing assembly 315 includes a second mounting block 3151, a second pressing head 3153 and a third driving member 3152.

As shown in fig. 12 and 13, in use, the positions of the three sets of second pressing members 315 in the y-axis direction can be adjusted according to the positions on the track 90 to be corrected. Meanwhile, the second pressing heads 3153 of any one or two sets of second pressing assemblies 315 may be selected to support the rail 90, and correspondingly, the second pressing heads 3153 of the other sets of second pressing assemblies 315 may be moved along the second sliding grooves 3151a to a position away from the rail 90 for avoiding. Correspondingly, two sets or one set of the first pressing assemblies 314 at corresponding positions can be selected, and the first pressing heads 3143 of the first pressing assemblies 314 correspond to the positions of the rails 90, and correspondingly, the first pressing heads 3143 of the other sets of the first pressing assemblies 314 move to positions far away from the rails 90 along the first sliding grooves 3141a for avoiding. The first pressing member 314 cooperates with the second pressing member 315 to align or bend the corresponding position of the rail 90.

Further, as shown in fig. 9 to 11, the first calibration mechanism 31 further includes a calibration detecting component 317 for detecting the deformation amount of the rail 90 during the top bending or straightening process. In the embodiment, three sets of calibration detecting elements 317 are provided, and the three sets of calibration detecting elements 317 are respectively provided at the positions of the three sets of second pressing elements 315. Specifically, one of the calibration detecting assemblies 317 is fixedly disposed at the end of the middle second pressing assembly 315, and is disposed corresponding to the center line of the second pressing assembly 315, that is, the center line of the second sliding groove 3151 a. The other two sets of calibration detecting elements 317 are respectively disposed at the sides of the other two sets of second pressing elements 315, and are symmetrically disposed with respect to the middle set of calibration detecting elements 317. The distance between the two alignment detection assemblies 317 located on both sides may be set to one meter, so that the three alignment detection assemblies 317 indirectly represent the straightness of the track 90 per unit length. In the embodiment, the three sets of calibration detecting elements 317 have the same structure, and are alternatively described below.

The calibration detecting assembly 317 includes an adapter plate 3172, a measuring rod 3171, an elastic member 3178, a fifth driving member 3177, and a grating detecting assembly (not shown). The adapting plate 3172 is fixedly mounted on the corresponding second mounting bracket 3151. One end of the fifth driving member 3177 is fixedly connected to one end of the adapting plate 3172, the other end of the fifth driving member 3177 is fixedly connected to the fixing block 3173, and the fixing block 3173 is fixedly connected to the other end of the adapting plate 3172.

The measuring rod 3171 is disposed parallel to the second sliding groove 3151a, i.e., the measuring rod 3171 is disposed along the x-axis direction. The measuring rod 3171 is slidably disposed with respect to the fixed block 3173. Specifically, one end of the measuring rod 3171 is fixedly connected with a connecting rod 3175, one side of the connecting rod 3175 close to the fixed block 3173 is fixedly provided with a second sliding rail 3176, correspondingly, the fixed block 3173 is fixedly provided with a sliding block 3174 matched with the second sliding rail 3176, the second sliding rail 3176 can slide relative to the sliding block 3174, and the sliding direction of the second sliding rail 3176 relative to the sliding block 3174 is parallel to the correcting direction of the first correcting mechanism 31, that is, arranged along the z-axis. Thus, the synchronous lifting movement of the second sliding rail 3176 and the measuring bar 3171 can be realized.

The connecting rod 3175 is fixedly connected to the output shaft of the fifth driving member 3177, and the fifth driving member 3177 can drive the connecting rod 3175 to move up and down, so as to drive the measuring rod 3171 to lift. One end of the elastic member 3178 is fixedly connected to the fixing block 3173, and the other end of the elastic member 3178 is fixedly connected to one end of the connecting rod 3175 away from the measuring rod 3171. Meanwhile, the elastic member 3178 is in a stretched state, so that the measuring stick 3171 is driven to move upward by the elastic force of the elastic member 3178.

In an embodiment, the grating detection assembly may include a scale grating disposed along the second sliding track 3176 and a grating read head disposed on a side of the slider 3174 near the second sliding track 3176. Thus, the moving distance of the second sliding rail 3176 can be measured by the grating detection assembly.

In use, when the position of the track 90 is adjusted, the fifth driving member 3177 overcomes the elastic force of the elastic member 3178 to drive the measuring rod 3171 to move downward for a certain distance, so that the measuring rod 3171 is separated from the track 90, and the problems of friction, collision and the like between the measuring rod 3171 and the track 90 in the moving process are avoided. After the track 90 is moved to the proper position, the fifth driving member 3177 may be in a failure state, and the measuring rod 3171 abuts against the side of the track 90 close to the second pressing member 315 under the elastic force of the elastic member 3178, which can be understood as the measuring rod 3171 abuts against the lower surface of the track 90. Therefore, in the straightening or bending process, the corresponding measuring rod 3171 can be driven to move along with the deformation of the rail 90, and then the moving distance of the measuring rod 3171, namely the deformation amount of the rail 90, is obtained through the detection of the grating detection assembly. The elastic member 3178 is disposed such that the measuring rod 3171 always abuts against the surface of the track 90. In an embodiment, fifth drive 3177 may be a hydraulic cylinder. The elastic member 3178 may be a spring.

In other embodiments, the fifth driving member 3177 may also be configured as a cylinder. The elastic member 3178 may also be a spring plate or an elastic rope.

In one embodiment, the input and output ends of the first calibration mechanism 31 are each provided with a set of first transport assemblies 61, which can be used for the transport of the rail 90. The first supporting blocks 611 of the two sets of first transmission assemblies 61 can be fixedly connected to the supporting seat 3112.

Further, the base mechanism 33 further includes a protective cover 333, the protective cover 333 is covered on the side of the base 331 where the third slide rail 3311 is disposed to protect the structures such as the third slide rail 3311, the eleventh driving member, and the lead screw, which are located on the base 331, from entering impurities to affect the movement of the first correcting mechanism 31. In an embodiment, the shield 333 may be a concertina shield. The protective cover 333 may be provided with two sections, wherein one end of the protective cover 333 is fixedly connected to a side of the frame 3111 away from the supporting seat 3112, and the other end is fixedly connected to an end of the base 331 away from the supporting seat 3112. One end of the other protective cover 333 can be connected to the side of the supporting seat 3112 away from the rack 3111, and the other end can be connected to the end of the base 331 away from the rack 3111. The shield 333 is driven to expand or contract while the first correcting mechanism 31 is moved.

In use, when the second correcting mechanism 32 is needed to correct the track 90, the first correcting mechanism 31 can be driven by the base mechanism 33 to be away from the track 90, so as to provide a space for deformation of the track 90, and prevent the first correcting mechanism 31 from interfering with correction of the track 90.

As shown in fig. 2 and fig. 14, the structure of the second correcting mechanism 32 and the structure of the first correcting mechanism 31 are orthogonal to each other, that is, the second correcting mechanism 32 can be obtained after the first correcting mechanism 31 rotates 90 °, and the detailed structure of the second correcting mechanism 32 is not described herein again. The correcting direction of the second correcting mechanism 32 is perpendicular to both the correcting direction of the first correcting mechanism 31 and the length direction of the track 90, i.e. the second correcting mechanism 32 can straighten and bend the track 90 in the x-axis direction.

As shown in fig. 1 and 2, the second blanking unit 40 is disposed near the output end of the calibration unit 30, and is configured to receive the calibrated rail 90 to realize blanking.

The second feeding unit 40 includes a plurality of sets of third supporting members 41, and the plurality of sets of third supporting members 41 are uniformly arranged along the length direction of the rail 90 at intervals, so that each portion of the rail 90 can be supported. The third supporting assembly 41 extends from the third loading end 40a to the third unloading end 40b, and is perpendicular to the length direction of the rail 90. In the embodiment, the structures of the multiple sets of third supporting members 41 are the same, and they are alternatively described below.

In the embodiment, the plurality of sets of second transmission assemblies 62 are disposed corresponding to the output end of the calibration unit 30, that is, disposed in the output direction of the calibration unit 30, and the plurality of sets of second transmission assemblies 62 are disposed at intervals along the length direction of the track 90. The plurality of sets of second conveying assemblies 62 and the plurality of sets of third supporting assemblies 41 are disposed in a staggered manner, and the second conveying assemblies 62 are disposed at the third loading end 40 a. An end of the third support member 41 adjacent to the third feeding end 40a may extend to the transfer path of the second transfer member 62. The plurality of second transmission assemblies 62 are identical in structure and will be described alternatively below.

The second transmission assembly 62 may include a second conveying roller 622, a seventh driving member 621 and a second supporting block 623, and the seventh driving member 621 is fixedly mounted on the second supporting block 623. The second conveying roller 622 is connected to an output shaft of the seventh driving member 621, and the seventh driving member 621 can drive the second conveying roller 622 to rotate so as to drive the track 90 to move. The axis of the second conveyor roller 622 is disposed along the horizontal direction, and is perpendicular to the length direction of the rail 90. In an embodiment, the upper surface of the second conveying roller 622 may be slightly higher than the upper surface of the third supporting component 41 in the vertical direction, so that the second conveying component 62 is prevented from being obstructed by the third supporting component 41 when conveying the track 90. Meanwhile, when the rail 90 is located on the second transmission assembly 62, the lower surface of the rail 90 is not higher than the height of the end of the third pushing assembly 42 for pushing, so that the third pushing assembly 42 pushes the rail 90 to move. In an embodiment, the seventh driving member 621 may be a motor.

In other embodiments, the second conveying roller 622 and the seventh driving member 621 may also be floatingly mounted on the second supporting block 623 by a hydraulic cylinder. When the rail 90 is transported, the second conveying roller 622 and the seventh driving member 621 may be lifted to a certain height relative to the third supporting assembly 41 to disengage the rail 90 from the third supporting assembly 41, so as to prevent the third supporting assembly 41 from interfering with the transportation of the rail 90. After the track 90 is output to the proper position, the second conveying roller 622 can be lowered to place the track 90 on the third supporting assembly 41, so that the third pushing assembly 42 can push the track 90 from the third loading end 40a to the third unloading end 40 b.

Further, a set of second transmission assemblies 62 may be disposed between the first correcting mechanism 31 and the second correcting mechanism 32, and may be used for the transportation of the rail 90.

In the embodiment wherein the track correction device further comprises a hydraulic unit 80, it will be appreciated that each hydraulic cylinder in the track correction device may be connected to the hydraulic unit 80, with hydraulic power being provided to the hydraulic cylinder by the hydraulic unit 80.

It is understood that each electrical component of the track calibration device can be electrically connected to the control unit 70, and the control unit 70 controls the operation of each component of the track calibration device. In an embodiment, a PLC (Programmable Logic Controller) Controller may be disposed in the control unit 70 to implement an automatic operation of the track correction device. During operation, the operator may also set various operating parameters of the track correction device via the control unit 70.

During operation, an operator can place the rail 90 at the first feeding end 10a of the feeding unit 10, and then push the rail 90 to the first discharging end 10b by the first pushing assembly 12, so that the rail 90 corresponds to the first transmission assembly 61. The first conveying assembly 61 can lift the rail 90 for a certain distance to separate the rail 90 from the feeding unit 10, and the feeding unit 10 can move away from the first conveying assembly 61 to avoid the detecting unit 50. Subsequently, the carriage 51 may be moved along the length direction of the rail 90 to detect the straightness of each portion of the rail 90, that is, to pre-detect the straightness of the rail 90. When the linearity of the rail 90 is satisfactory, the first unloading unit 20 moves to a direction close to the support table 52, and the second loading end 20a extends into the conveying path of the first conveying assembly 61. The first delivery roller 615 descends to drop the rail 90 on the first blanking unit 20, and then the second pushing assembly 22 can push the rail 90 from the second feeding end 20a to the second blanking end 20b, so that an operator can take off the rail 90 to realize blanking. For pre-inspecting defective tracks, first transport assembly 61 may incrementally transport track 90 into calibration unit 30 for straightening or top bending. After all parts of the same rail 90 are straightened or bent, the rail 90 can be conveyed back to the upper part of the support table 52 by the first transmission assembly 61 and the second transmission assembly 62, the straightness of the rail 90 is rechecked by the detection unit 50, and when the parts are still unqualified, the corresponding parts of the rail 90 can be sent into the correction unit 30 again for straightening or bending. When the rail 90 is qualified, the first transmission assembly 61 and the second transmission assembly 62 cooperate to transport the rail 90 from above the support platform 52 to the third loading end 40a of the second unloading unit 40, and the second unloading unit 40 unloads the rail 90.

Taking the first calibration mechanism 31 for calibrating the track 90 as an example, the control unit 70 may control the second pressing assembly 315 in the first calibration mechanism 31 to adjust the position and adjust the corresponding first pressing head 3143 and second pressing head 3153 to the proper position. The first driving member 312 is then controlled by the control unit 70 to move the corresponding first pressing head 3143 downward, so as to straighten or bend the rail 90 under the cooperation of the first pressing head 3143 and the second pressing head 3153. During straightening or top bending, the calibration detecting assembly 317 may detect the deformation amount of the rail 90 in real time, so that the control unit 70 controls the first pressing head 3143 to act according to the detection result. During the alignment process, the first feeding roller 615 of the first conveying assembly 61 moves downward to be separated from the rail 90, so as to avoid interference with the alignment of the rail 90. In the embodiment, the straightening and bending processes of the second correction mechanism 32 are the same as the first correction mechanism 31, and are not described herein again. It is understood that when the second correction mechanism 32 corrects the track 90, the first conveying roller 615 may not need to be detached from the track 90.

In an embodiment, the first correction mechanism 31 and the second correction mechanism 32 can perform two-dimensional alignment and bending on the rail 90, that is, alignment and bending on the rail 90 in multiple directions are achieved, time waste caused by turning over the rail 90 for multiple times in an operation process is avoided, and therefore work efficiency can be improved.
