DETAILED DESCRIPTION

[0025] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0026] like Figure 1 As shown, a Cartesian coordinate system is established to define an x-axis, a y-axis, and a z-axis, wherein the length direction of the track 80 is arranged along the y-axis.

[0027] In the embodiment, a track correction device is provided, which can be used for straightening and bending a track 80 such as a railway track, so that the track 80 meets construction requirements.

[0028] like Figure 1 As shown, the track correction device includes a loading unit 10, a first correction unit 20, a second correction unit 30, and a unloading unit 40, which are arranged in sequence. The loading unit 10 is arranged at the input end of the first correction unit 20 and can be used to transport the track 80 to the first correction unit 20. The output end of the first correction unit 20 is connected to the input end of the second correction unit 30. The unloading unit 40 is arranged at the output end of the second correction unit 30.

[0029] During operation, the operator places the track 80 onto the loading unit 10, which then transports it to the first calibration unit 20. The first and second calibration units 20 and 30 calibrate the track 80, straightening or bending it. After calibration, the track 80 can be unloaded from the unloading unit 40. Once the track 80 is fully unloaded, the operator removes it from the unloading unit 40.

[0030] The correction direction of the first correction unit 20 is perpendicular to the correction direction of the second correction unit 30. It is understood that the correction directions of the first correction unit 20 and the second correction unit 30 are both perpendicular to the length of the track 80. Thus, the track correction device can correct the track 80 in two dimensions, eliminating the need to repeatedly flip the track 80 to achieve corrections at different positions during the correction process. This can improve the correction efficiency of the track 80, and thus improve operational efficiency.

[0031] In some specific embodiments, such as Figure 1 As shown, the track correction equipment also includes a main control unit 50, and the loading unit 10, the first correction unit 20, the second correction unit 30 and the unloading unit 40 are all electrically connected to the main control unit 50, so that the main control unit 50 can control and coordinate the work of other units.

[0032] like Figure 1As shown, the loading unit 10 includes a first support mechanism 11, a first conveying mechanism 12, a detection mechanism 13, and a support platform 14. Multiple sets of first support mechanisms 11 are provided, and the multiple sets of first support mechanisms 11 are spaced apart along the length of the track 80. In some specific embodiments, the multiple sets of first support mechanisms 11 can be evenly spaced and arranged in parallel, thereby supporting various parts of the track 80. In this embodiment, the structures of the multiple sets of first support mechanisms 11 are identical, and one of them will be described below.

[0033] like Figure 3 and Figure 4 As shown, in some specific embodiments, the first support mechanism 11 includes a support leg 111, a bracket 112, a pusher assembly 113, and a drive assembly 114. The bracket 112 has a certain length, and the length of the bracket 112 extends perpendicular to the length of the track 80. The support leg 111 is fixedly connected to the bracket 112 and is used to support the bracket 112.

[0034] The bracket 112 includes a loading end 112a and a unloading end 112b. The unloading end 112b is located on the side corresponding to the input end of the first calibration unit 20. During use, the operator can place the track 80 on the loading end 112a of the bracket 112. The pusher assembly 113 is slidably mounted on the bracket 112. The drive assembly 114 is connected to the pusher assembly 113 and is used to drive the pusher assembly 113 to move along the length of the bracket 112. Driven by the drive assembly 114, the pusher assembly 113 can push the track 80 from the loading end 112a to the unloading end 112b, so that the track 80 can be subsequently transported to the first calibration unit 20.

[0035] In some specific embodiments, the pusher assembly 113 includes a sliding base 1131 and a pusher rod 1132, and the sliding base 1131 is connected to the drive assembly 114. The end of the pusher rod 1132 away from the discharge end 112b is hinged to the sliding base 1131, and a torsion spring (not shown) is provided between the pusher rod 1132 and the sliding base 1131. The end of the pusher rod 1132 away from the hinge can be tilted relative to the sliding base 1131 under the action of the torsion spring, and the end of the pusher rod 1132 away from the hinge is protruding from the upper surface of the bracket 112, that is, a surface of the bracket 112 away from the support leg 111. As a result, one end of the pusher rod 1132 can contact the track 80 to push the track 80 to move.

[0036] The bracket 112 has a mounting slot 1121 disposed therein, with an opening for communication with the outside world disposed on a side of the mounting slot 1121 away from the support leg 111. The drive assembly 114 and the pusher assembly 113 are mounted in the mounting slot 1121, with one end of the pusher rod 1132 protruding from the upper surface of the bracket 112 through the opening of the mounting slot 1121.

[0037] The drive assembly 114 includes a tenth drive member (not shown), a transmission belt 1143, and a first transmission wheel 1142. The tenth drive member can be fixedly mounted on the discharge end 112b of the bracket 112. Two first transmission wheels 1142 are provided, one located at the feed end 112a and the other at the discharge end 112b of the bracket 112. Both first transmission wheels 1142 are rotatably mounted on the bracket 112. Taking the first transmission wheel 1142 located at the feed end 112a as an example, a mounting base 1141 is fixedly mounted on the end surface of the bracket 112. The first transmission wheels 1142 are rotatably mounted on the mounting base 1141 via a rotating shaft 1144. The tenth drive member can be connected to the first transmission wheel 1142 located at the discharge end 112b. The transmission belt 1143 is transmission-connected between the two first transmission wheels 1142. The sliding base 1131 is fixedly connected to the transmission belt 1143. Thus, the tenth driving member drives the transmission belt 1143, thereby driving the pusher assembly 113 to reciprocate, thereby achieving the pushing action and reset of the pusher assembly 113. The transmission belt 1143 and the first transmission wheel 1142 can be meshed with each other via meshing teeth, thereby preventing slippage between the transmission belt 1143 and the first transmission wheel 1142. In this embodiment, the tenth driving member can be a motor.

[0038] In other embodiments, the transmission belt 1143 and the first transmission wheel 1142 may also be a combination of a belt and a pulley to achieve an anti-slip effect through friction.

[0039] Furthermore, in some embodiments, the first support mechanism 11 also includes a reset sensor 115 for detecting the actions of the pusher assembly 113, including pushing and resetting, so as to prepare for the next push. Specifically, the reset sensor 115 may be a plate-shaped structure, the reset sensor 115 is fixedly mounted on one end of the bracket 112 close to the loading end 112a, and the reset sensor 115 is fixedly mounted on one side of the opening of the mounting groove 1121. When the pusher rod 1132 is in a natural state, the end of the pusher rod 1132 away from the hinge may protrude from the plane where the reset sensor 115 is located, so that when the pusher rod 1132 passes through the reset sensor 115, it may touch the reset sensor 115, thereby triggering the reset sensor 115. A gap is provided between the bottom surface of the reset sensor 115 and the upper surface of the sliding base 1131. When the push rod 1132 turns over and abuts against the end of the sliding base 1131 near the feeding end 112a, the gap should allow the push rod 1132 to pass smoothly. In the embodiment, a wire box 1151 is fixedly provided on one side of the bracket 112 for protecting the wires connected to the reset sensor 115.

[0040] When the track 80 needs to be pushed, the pusher assembly 113, driven by the drive assembly 114, passes the reset sensor 115. The reset sensor 115 abuts the lower surface of the pusher rod 1132, and the pusher rod 1132 flips toward the upper feeding end 112a under the action of the reset sensor 115. After the pusher assembly 113 passes the reset sensor 115, the pusher rod 1132 flips and resets toward the lower feeding end 112b. When the pusher rod 1132 contacts the track 80, the front end surface of the pusher rod 1132 can completely fit the surface of the track 80, thereby pushing the track 80 to move.

[0041] When the pusher assembly 113 is reset, the pusher rod 1132 can rotate toward the interior of the sliding base 1131 under the squeezing action of the reset sensor 115 to be retracted into the sliding base 1131 so as to pass through the reset sensor 115. At the same time, the pusher rod 1132 will trigger the reset sensor 115, indicating that the pusher assembly 113 has moved to the loading end of the bracket 112, and the tenth driving member can stop moving. In some specific embodiments, the reset sensor 115 can be a contact switch. It is understandable that during the reset process of the pusher assembly 113, when the reset sensor 115 is triggered, the main control unit 50 can set a certain delay time when controlling the tenth driving member to stop moving, so that the pusher rod 1132 can be completely separated from the reset sensor 115, avoiding the reset sensor 115 and the pusher rod 1132 being in a mutually squeezed state for a long time, so as to protect the reset sensor 115 and the pusher rod 1132.

[0042] In other embodiments, the reset sensing element 115 may also be a non-contact sensor, such as an infrared sensor, a Hall sensor, etc. It is understood that when the reset sensing element 115 is a Hall sensor, a corresponding magnetic element such as a magnet may be provided on the pusher assembly 113 to trigger the Hall sensor.

[0043] like Figure 1 As shown, the first conveying mechanism 12 is also provided with multiple groups, and the multiple groups of first conveying mechanisms 12 are spaced apart along the length direction of the track 80. In the embodiment, the multiple groups of first conveying mechanisms 12 can be evenly spaced, and the multiple groups of first conveying mechanisms 12 are staggered with the multiple groups of first support mechanisms 11. The first conveying mechanism 12 is arranged near the unloading end 112b of the bracket 112, and the conveying direction of the first conveying mechanism 12 is arranged along the length direction of the track 80. During operation, after the pushing assembly 113 pushes the track 80 to the unloading end 112b, it can be taken over by the first conveying mechanism 12, and then the first conveying mechanism 12 transports the track 80 along the length direction of the track 80. The structures of the multiple groups of first conveying mechanisms 12 are the same, and one of them will be introduced below.

[0044] like Figure 2 As shown, the first conveying mechanism 12 includes a third driving member 121 and a first conveying roller 122. The third driving member 121 is used to drive the first conveying roller 122 to rotate. In some specific embodiments, the first conveying mechanism 12 further includes a support block 123, a floating plate 125 and a fourth driving member (not shown).

[0045] The first conveyor roller 122 and the third driving member 121 are mounted on the floating plate 125 via a fixed base 1251. The floating plate 125 is floatingly mounted on the support block 123 via a fourth driving member. During use, the fourth driving member can drive the floating plate 125 to move up and down, causing the first conveyor roller 122 to contact or move away from the track 80. When the first conveyor roller 122 contacts the track 80, the conveyor roller 122 can move along the track 80. When the first conveyor roller 122 moves away from the track 80, the first conveyor roller 122 no longer acts on the track 80. In this embodiment, a fifth guide rod 124 is further connected between the support block 123 and the floating plate 125. One end of the fifth guide rod 124 is fixedly connected to the side of the floating plate 125 closest to the support block 123, and the other end of the fifth guide rod 124 is retractably mounted on the support block 123. This guide rod 124 guides the floating plate 125 during its movement and prevents it from tilting during movement. In some specific embodiments, the third driving member 121 may be a motor with an encoder, and the fourth driving member may be a hydraulic cylinder.

[0046] In other embodiments, the third driving member 121 may also be a hydraulic cylinder with a gear transmission assembly and a clutch to drive the first conveying roller 122 to rotate. The fourth driving member may also be an electric push rod, a cylinder, a motor with a screw rod, etc. to drive the floating plate 125 to rise and fall.

[0047] The support platform 14 is fixed relative to the first calibration unit 20. The support platform 14 is connected to the input end of the first calibration unit 20 and is located near the unloading end 112b of the bracket 112. The first conveying mechanism 12 is mounted on the support platform 14. Specifically, the support block 123 is fixedly mounted on the support platform 14.

[0048] In the embodiment, the loading unit 10 further includes a plurality of sets of third moving mechanisms 15, which are arranged in a one-to-one correspondence with the first support mechanism 11. The third moving mechanism 15 is used to drive the first support mechanism 11 to slide relative to the support platform 14. Specifically, the third moving mechanism 15 may include a sliding seat 151, a second slide rail 152, and an eleventh driving member (not shown). The sliding seat 151 is slidably mounted on the second slide rail 152, and the second slide rail 152 is fixedly arranged relative to the support platform 14. In the embodiment, the second slide rail 152 can be fixedly mounted on the ground. The extension direction of the second slide rail 152 is perpendicular to the length direction of the track 80. The support leg 111 of the first support mechanism 11 can be fixedly mounted on the sliding seat 151. The eleventh driving member is used to drive the sliding seat 151 to slide along the second slide rail 152 to approach or move away from the support platform 14, thereby driving the unloading end 112b of the bracket 112 to approach or move away from the first conveying mechanism 12. When the unloading end 112b is close to the first conveying mechanism 12, the unloading end 112b can be located on the conveying path of the conveying track 80 of the first conveying mechanism 12. It can be understood that the multiple sets of third moving mechanisms 15 can be controlled by the main control unit 50 to perform synchronous movements, thereby achieving synchronous movements of the multiple sets of first supporting mechanisms 11.

[0049] When loading, the eleventh driving member can first drive the unloading end 112b of the bracket 112 close to the first conveying mechanism 12. The pushing assembly 113 can push the track 80 from the loading end 112a to the unloading end 112b. When the track 80 is located at the unloading end 112b, the fourth driving member can drive the floating plate 125 to rise so that the first conveying roller 122 contacts the track 80 and lifts the track 80 a certain distance to separate the track 80 from the bracket 112. Subsequently, the eleventh driving member can drive the first supporting mechanism 11 away from the first conveying mechanism 12 so that the unloading end 112b of the bracket 112 is away from the conveying path of the first conveying mechanism 12. Thus, the first conveying mechanism 12 supports the track 80 and realizes the transportation of the track 80. In the embodiment, the eleventh driving member can be selected from one of the structures such as a motor, a cylinder, and a hydraulic cylinder.

[0050] In other embodiments, the third moving mechanism 15 may be provided in a group, and accordingly, the support legs 111 of multiple groups of first supporting mechanisms 11 are fixedly mounted on the same sliding seat 151. One group of third moving mechanisms 15 simultaneously drives multiple groups of first supporting mechanisms 11 to move synchronously.

[0051] like Figure 1 As shown, the detection mechanism 13 can be slidably mounted on the support platform 14. The detection mechanism 13 can be used for pre-inspection and re-inspection of the straightness of the track 80. Specifically, a pair of first slide rails 141 are fixedly mounted on the side of the support platform 14 close to the first conveying mechanism 12. The extension direction of the first slide rails 141 is arranged along the length direction of the support platform 14, that is, along the length direction of the track 80. The detection mechanism 13 includes a sliding frame 131 of a door frame structure, and the two ends of the sliding frame 131 are slidably mounted on the first slide rails 141 on the corresponding side. A laser detector is respectively provided on the three inner side walls of the sliding frame 131, and the three groups of laser detectors can cooperate to perform straightness detection on the track 80 in two dimensions. A twelfth driving member (not shown) that drives the sliding frame 131 to slide along the first slide rail 141 is also provided inside the support platform 14. The twelfth driving member can be a motor, a cylinder, a hydraulic cylinder or other components. During operation, when the first support mechanism 11 exits the transport path of the track 80, the twelfth drive member drives the carriage 131 to move along the length of the track 80, from one end to the other. Three laser detectors coordinately check the straightness of various sections of the track 80 and record this information along with the track 80's position.

[0052] The initial position of the carriage 131 should be between the track 80 and the first correction unit 20, that is, at the front end of the track 80. During the inspection process, the end position of the carriage 131 should be on the side of the track 80 away from the first correction unit 20, and at a certain distance from the end of the track 80. This facilitates determining whether the inspection has begun and completed when the laser detector is used to inspect the straightness of the track 80, and also facilitates the laser detector to obtain corresponding position information, so that the position information corresponds to the straightness. At the same time, the initial position information of the track 80 can be accurately obtained, facilitating the control of the distance the track 80 moves each time during subsequent operations. It will be understood that the initial position of the carriage 131 is fixed, that is, the inspection mechanism 13 returns to its initial position after each inspection.

[0053] After the first and second calibration units 20 and 30 have completed a calibration of the track 80, the track 80 can be returned to the loading unit 10, where the inspection mechanism 13 re-inspects the straightness of the track 80 to confirm that the calibration is accurate. If it is detected that some portions of the track 80 still do not meet the straightness requirements, the first and / or second calibration units 20 and 30 can perform further calibration until the requirements are met.

[0054] Combine Figure 1 、 Figures 5 to 8 As shown, the first correction unit 20 can be used to straighten and bend the track 80 in the vertical direction, that is, straighten and bend along the z-axis.

[0055] In some specific embodiments, the first correction unit 20 includes a first frame 22, a first driving member 23, a first pressing mechanism 25 and a first supporting mechanism 26. Among them, the first frame 22 includes a first shell 221 and a first support seat 222. The first shell 221 can be in an inverted L shape, and the horizontal section of the first shell 221 can be arranged corresponding to the upper part of the first support seat 222. In the embodiment, the first driving member 23 is fixedly installed inside the horizontal section of the first shell 221. The first pressing mechanism 25 is connected to the first output shaft 231 of the first driving member 23. The first supporting mechanism 26 is installed on the side of the first support seat 222 close to the first driving member 23. During use, the first driving member 23 can drive the first pressing mechanism 25 to move up and down to approach or move away from the first supporting mechanism 26. In the embodiment, the first driving member 23 can optionally use a hydraulic cylinder.

[0056] In other embodiments, the first driving member 23 may also be a motor, an electric push rod, a cylinder or other structures to drive the first pressing mechanism 25 to move up and down.

[0057] like Figure 7 and Figure 8 As shown, the first pressing mechanism 25 can be connected to the first output shaft 231 via the first adapter frame 24. Specifically, the first adapter frame 24 is fixedly connected to the first output shaft 231, and the first pressing mechanism 25 is mounted on a side of the first adapter frame 24 near the first support seat 222. In this embodiment, three groups of first pressing mechanisms 25 are provided, evenly spaced along the length of the first adapter frame 24. The length of the first adapter frame 24 is arranged along the length of the track 80. During use, the first drive member 23 can drive the first adapter frame 24 to rise and fall, thereby driving the three groups of first pressing mechanisms 25 to rise and fall simultaneously.

[0058] In other embodiments, the first pressing mechanisms 25 may also be provided in two groups, five groups, six groups, seven groups, etc., which are not specifically limited here.

[0059] In an embodiment, the first calibration unit 20 may further include a displacement sensor 21 for detecting the displacement of the first adapter frame 24 when it is raised or lowered. The displacement sensor 21 may be fixedly mounted on the first driving member 23 .

[0060] Two sets of symmetrical guide assemblies are also provided between the first adapter frame 24 and the first shell 221, which are used to guide the lifting and lowering movement of the first adapter frame 24, prevent the first adapter frame 24 from tilting, and ensure the precise movement of the first pressing mechanism 25. Specifically, the guide assembly includes a first guide rod 241 and a first guide sleeve 2211. The first guide sleeve 2211 can be fixedly mounted on the outer wall of the first shell 221. One end of the first guide rod 241 can be fixedly connected to the first adapter frame 24, and the other end of the first guide rod 241 can be arranged through the first guide sleeve 2211 at a corresponding position. The diameter of the first guide rod 241 can be equal to the inner diameter of the first guide sleeve 2211, and the first guide rod 241 can slide smoothly relative to the first guide sleeve 2211.

[0061] The three groups of first pressing mechanisms 25 have the same structural arrangement, and one of them will be introduced below.

[0062] The first pressing mechanism 25 includes a first mounting rail 251, a pressure block 252 and a second driving member 253. The first mounting rail 251 is fixedly mounted on the first adapter frame 24. The pressure block 252 is slidably mounted on the side of the first mounting rail 251 away from the first adapter frame 24, and the first mounting rail 251 is provided with a first slide groove 2511 for the pressure block 252 to slide. In the embodiment, the first slide groove 2511 can be a dovetail groove, and accordingly, the shape of the side of the pressure block 252 close to the first mounting rail 251 can match the first slide groove 2511, so that the pressure block 252 can be confined in the first slide groove 2511 in the vertical direction to prevent the pressure block 252 from detaching from the first mounting rail 251. The extension direction of the first slide groove 2511 is set in the horizontal direction and is perpendicular to the length direction of the track 80, that is, it is set along the x-axis direction. In the embodiment, a side of the pressing block 252 close to the first supporting mechanism 26 is protruded from the lower surface of the first mounting rail 251 , that is, a surface of the first mounting rail 251 close to the first supporting mechanism 26 .

[0063] The second driving member 253 can be a rodless hydraulic cylinder. The second driving member 253 is fixedly connected to the pressure block 252 via a first connecting plate 255. The second driving member 253 is slidably mounted on one side of the first mounting rail 251 via a second guide rod 254. Both ends of the second guide rod 254 are fixedly mounted to the sidewalls of the first mounting rail 251. The second driving member 253 is sleeved on the second guide rod 254 and can slide along the second guide rod 254. The second guide rod 254 is arranged parallel to the first slide groove 2511.

[0064] like Figure 7 and Figure 8As shown, the first supporting mechanism 26 can be movably mounted on the side of the first support seat 222 close to the first pressing mechanism 25 through the first moving mechanism 28. Specifically, the first moving mechanism 28 includes a third mounting plate 281, a transmission rod 282, a second transmission wheel 283 and a seventh driving member 284. Among them, the third mounting plate 281 is fixedly mounted on the first support seat 222, and the length direction of the third mounting plate 281 is set along the length direction of the track 80. The transmission rod 282 is rotatably mounted on the third mounting plate 281, and the transmission rod 282 is parallel to the length direction of the third mounting plate 281. Both ends of the transmission rod 282 can be rotatably connected to the third mounting plate 281 through bearings (not shown). One end of the transmission rod 282 is fixedly connected to the second transmission wheel 283, and the seventh driving member 284 and the second transmission wheel 283 can be connected to each other through a corresponding transmission belt.

[0065] In an embodiment, the seventh driving member 284 can be fixedly mounted on one end of the first support base 222 near the second transmission wheel 283 so that the seventh driving member 284 is connected to the second transmission wheel 283. The second transmission wheel 283 and the corresponding transmission belt can be engaged with each other by meshing teeth to prevent slipping between the second transmission wheel 283 and the transmission belt, thereby achieving stable transmission motion. In an embodiment, the transmission rod 282 can be a screw rod, and the first supporting mechanism 26 can be provided with a nut sleeve (not shown) that cooperates with the transmission rod 282 to achieve a threaded connection between the first supporting mechanism 26 and the transmission rod 282. In some specific embodiments, the transmission rod 282 can be embedded in the interior of the third mounting plate 281, and accordingly, the nut sleeve connected to the first supporting mechanism 26 extends into the interior of the third mounting plate 281 and is threadedly connected to the transmission rod 282. The first supporting mechanism 26 is supported on a side of the third mounting plate 281 near the first pressing mechanism 25. Thus, the first supporting mechanism 26 will not rotate with the transmission rod 282. When the seventh driving member 284 drives the transmission rod 282 to rotate, the first supporting mechanism 26 can be driven to move along the length direction of the transmission rod 282. In an embodiment, the seventh driving member 284 can be a motor.

[0066] In other embodiments, the seventh driving member 284 may also be a cylinder, a hydraulic cylinder or other structures.

[0067] In this embodiment, three sets of first supporting mechanisms 26 are also provided, equal in number to the number of first pressing mechanisms 25. The three sets of first supporting mechanisms 26 can be evenly spaced along the length of the third mounting plate 281. The three sets of first supporting mechanisms 26 have the same structure, and one of them will be described below.

[0068] Specifically, the first supporting mechanism 26 includes a second mounting rail 261, a supporting block 262, and a fifth driving member 263. The nut sleeve can be fixedly disposed on a side of the second mounting rail 261 close to the third mounting plate 281, that is, the second mounting rail 261 is mounted on the first moving mechanism 28. The supporting block 262 is slidably mounted on a side of the second mounting rail 261 close to the first pressing mechanism 25. The second mounting rail 261 is provided with a second slide groove 2611 for mounting the supporting block 262, and the supporting block 262 is slidably disposed in the second slide groove 2611. The second slide groove 2611 can also be a dovetail groove structure. Accordingly, the shape of the supporting block 262 for connecting to the second slide groove 2611 can match the second slide groove 2611, so as to limit the supporting block 262 on the second mounting rail 261 in the vertical direction and prevent the supporting block 262 from detaching from the second mounting rail 261. The side of the support block 262 near the first pressing mechanism 25 protrudes from the upper surface of the second mounting rail 261, that is, a surface of the second mounting rail 261 near the first pressing mechanism 25. The extension direction of the second slide groove 2611 is set along the horizontal plane and perpendicular to the extension direction of the transmission rod 282.

[0069] In this embodiment, the fifth driving member 263 can be a rodless hydraulic cylinder. The fifth driving member 263 is fixedly connected to the support block 262 via a second connecting plate 265. The fifth driving member 263 is slidably mounted on one side of the second mounting rail 261 via a third guide rod 264. The third guide rod 264 can be arranged parallel to the second slide groove 2611, with both ends of the third guide rod 264 fixedly connected to the sidewalls of the second mounting rail 261. The fifth driving member 263 is slidably mounted on the third guide rod 264, thereby driving the support block 262 to slide along the second slide groove 2611.

[0070] like Figure 10 and Figure 11 As shown, during use, the positions of the three groups of first supporting mechanisms 26 in the y-axis direction can be adjusted according to the positions on the track 80 that need to be corrected. At the same time, the supporting blocks 262 in any one or two groups of the first supporting mechanisms 26 can be selected to support the track 80. Accordingly, the supporting blocks 262 in the other groups of the first supporting mechanisms 26 can be moved along the second slide groove 2611 to a position away from the track 80 for avoidance. Accordingly, two or one groups of the first pressing mechanisms 25 at corresponding positions can also be selected, and their pressing blocks 252 can be made to correspond to the positions of the track 80. Accordingly, the pressing blocks 252 in the other groups of the first pressing mechanisms 25 can be moved along the first slide groove 2511 to a position away from the track 80 for avoidance. The first pressing mechanism 25 can cooperate with the first supporting mechanism 26 to straighten or bend the corresponding position of the track 80.

[0071] Further, such as Figure 8 、 Figure 9 and Figure 12As shown, the first correction unit 20 also includes a first correction detection mechanism 27 for detecting the deformation of the track 80 during top bending or straightening. In the embodiment, three groups of first correction detection mechanisms 27 are provided, and the three groups of first correction detection mechanisms 27 are respectively arranged at the positions of the three groups of first support mechanisms 26. Specifically, one group of first correction detection mechanisms 27 is fixedly set at the end of the middle group of first support mechanisms 26 and is set corresponding to the center line of the group of first support mechanisms 26, that is, corresponding to the center line of the second slide 2611. The other two groups of first correction detection mechanisms 27 are respectively set on the sides of the other two groups of first support mechanisms 26 and are symmetrically arranged about the middle group of first correction detection mechanisms 27. The distance between the two first correction detection mechanisms 27 on both sides can be set to one meter, so that the three groups of first correction detection mechanisms 27 can indirectly represent the straightness of the unit length of the track 80. In the embodiment, the structures of the three groups of first correction detection mechanisms 27 are the same, and one of them will be introduced below.

[0072] The first calibration and detection mechanism 27 includes a second mounting plate 271, a measuring rod 277, an elastic member 278, a sixth driving member 275, and a grating detection assembly (not shown). The second mounting plate 271 is fixedly mounted on the corresponding second mounting rail 261. One end of the sixth driving member 275 is fixedly connected to one end of the second mounting plate 271 via a fifth connecting plate 272. The other end of the sixth driving member 275 is fixedly connected to the other end of the second mounting plate 271 via a third connecting plate 274 and an adapter 273. The adapter 273 is fixedly mounted on the second mounting plate 271, and the end of the third connecting plate 274 away from the sixth driving member 275 is fixedly connected to the adapter 273.

[0073] The measuring rod 277 is arranged parallel to the second slide slot 2611, that is, it is arranged along the x-axis. The measuring rod 277 slides relative to the adapter 273. Specifically, one end of the measuring rod 277 is fixedly connected to a connecting rod 276. A fourth slide rail 2761 is fixedly mounted on the side of the connecting rod 276 near the adapter 273. Accordingly, a slider 2731 is fixedly mounted on the adapter 273 to cooperate with the fourth slide rail 2761. The fourth slide rail 2761 can slide relative to the slider 2731. The sliding direction of the fourth slide rail 2761 relative to the slider 2731 is parallel to the correction direction of the first correction unit 20, that is, along the z-axis. This allows for synchronized lifting and lowering of the fourth slide rail 2761 and the measuring rod 277.

[0074] Connecting rod 276 is fixedly connected to the output shaft of sixth driver 275 via fourth connecting plate 279. Sixth driver 275 drives connecting rod 276 up and down, thereby moving measuring rod 277 upward and downward. One end of elastic member 278 is fixedly connected to adapter 273, while the other end is fixedly connected to the end of connecting rod 276 away from measuring rod 277. At the same time, elastic member 278 is in a stretched state, and thus, its elastic force drives measuring rod 277 upward.

[0075] In an embodiment, the grating detection assembly may include a scale grating and a grating reading head. The scale grating is disposed along the fourth slide rail 2761, and the grating reading head is disposed on a side of the slider 2731 close to the fourth slide rail 2761. Thus, the grating detection assembly can measure the movement distance of the fourth slide rail 2761.

[0076] During use, when adjusting the position of the track 80, the sixth driver 275 overcomes the elastic force of the elastic member 278 and drives the measuring rod 277 downward a certain distance, separating the measuring rod 277 from the track 80 and preventing friction and collision between the track 80 and the measuring rod 277 during movement. Once the track 80 is in position, the sixth driver 275 can be deactivated, and the elastic force of the elastic member 278 causes the measuring rod 277 to abut against the side of the track 80 near the first support mechanism 26. This can be understood as the measuring rod 277 abutting the lower surface of the track 80. Therefore, during straightening or bending, the deformation of the track 80 drives the corresponding measuring rod 277 to move. The grating detection assembly then detects the distance the measuring rod 277 has moved, i.e., the deformation of the track 80. The provision of the elastic member 278 ensures that the measuring rod 277 remains in contact with the surface of the track 80. In this embodiment, the sixth driver 275 can be a hydraulic cylinder, and the elastic member 278 can be a spring.

[0077] In other embodiments, the sixth driving member 275 may also be a cylinder or other structure. The elastic member 278 may also be a spring sheet, an elastic rope or other structure.

[0078] In the embodiment, a first conveying mechanism 12 is provided at both the input and output ends of the first correction unit 20 for conveying on the track 80 . The support blocks 123 in the two first conveying mechanisms 12 can be fixedly connected to the first support base 222 .

[0079] like Figure 1 、 Figure 5 and Figure 6As shown, further, the track correction device also includes a base unit 60, and the first correction unit 20 is installed on the base unit 60. The base unit 60 includes a base 61, and the first frame 22 can be slidably installed on the base 61. The sliding direction of the first frame 22 relative to the base 61 is perpendicular to the length direction of the track 80 and the correction direction of the first correction unit 20, that is, it is arranged along the x-axis direction. Specifically, a sliding plate 63 is fixedly connected to the side of the first frame 22 close to the base 61, and a third slide rail 611 that cooperates with the sliding plate 63 is provided on the base 61. The sliding plate 63 is slidably connected to the third slide rail 611, thereby realizing the sliding installation of the first frame 22 and the base 61.

[0080] In the embodiment, a thirteenth driving member (not shown) is further provided on the base 61 for driving the sliding plate 63 to slide along the third slide rail 611. In some specific embodiments, the thirteenth driving member can be a motor, and the output end of the motor can be connected to a lead screw (not shown), which is threadedly connected to the sliding plate 63.

[0081] Furthermore, the base unit 60 also includes a protective cover 62, which is provided on the side of the base 61 where the third slide rail 611 is provided, to protect the structures on the base 61, such as the third slide rail 611, the thirteenth drive member, and the lead screw, to prevent debris from entering and affecting the movement of the first frame 22. In an embodiment, the protective cover 62 can be an accordion-type protective cover. The protective cover 62 can be provided with two sections, wherein one end of the protective cover 62 can be fixedly connected to the side of the first shell 221 away from the first support seat 222, and the other end is fixedly connected to the end of the base 61 away from the first support seat 222. The other end of the protective cover 62 can be connected to the side of the first support seat 222 away from the first shell 221, and the other end can be connected to the end of the base 61 away from the first shell 221. As the first frame 22 moves, the protective cover 62 is driven to expand or contract.

[0082] During use, when the second correction unit 30 is needed to correct the track 80 , the first correction unit 20 can be driven away from the track 80 by the base unit 60 to provide space for the deformation of the track 80 and prevent the first correction unit 20 from interfering with the correction of the track 80 .

[0083] like Figure 1 and Figure 13 As shown, the structure of the second correction unit 30 is orthogonal to that of the first correction unit 20. That is, the second correction unit 30 can be obtained by rotating the first correction unit 20 by 90 degrees. The correction direction of the second correction unit 30 is perpendicular to both the correction direction of the first correction unit 20 and the length direction of the track 80. That is, the second correction unit 30 can straighten and bend the track 80 in the x-axis direction.

[0084] It is understandable that the second correction unit 30 may include a second frame 31, an eighth drive member 32, a second pressing mechanism 35 and a second supporting mechanism 36. The second frame 31 is arranged perpendicular to the first frame 22, and the second frame 31 includes a second shell 311 and a second support seat 312. The second shell 311 and the second support seat 312 form a U-shaped structure, and the track 80 can pass through the U-shaped structure. The eighth drive member 32 is fixedly mounted on the second shell 311, and the second output shaft 321 of the eighth drive member 32 passes through the second shell 311 and is arranged toward the second support seat 312, and the second pressing mechanism 35 is connected to the second output shaft 321 through the second adapter frame 34. The eighth drive member 32 can drive the second adapter frame 34 to approach or move away from the second support seat 312, thereby driving the second pressing mechanism 35 to move synchronously. In the embodiment, the eighth drive member 32 can optionally use a hydraulic cylinder.

[0085] In other implementations, the eighth driving member 32 may also be a motor, a cylinder, an electric push rod, or other structures.

[0086] In the embodiment, a fourth guide rod 33 is fixedly connected to the second adapter frame 34, and correspondingly, a second guide sleeve 3111 is fixedly provided on the second shell 311. The fourth guide rod 33 and the second guide sleeve 3111 are slidably matched to guide the movement of the second adapter frame 34 to prevent the second adapter frame 34 from being offset.

[0087] In some specific embodiments, three groups of second pressing mechanisms 35 are also provided and are evenly spaced along the length of the track 80. In the embodiment, the specific structure of the second pressing mechanism 35 is the same as that of the first pressing mechanism 25, and will not be repeated here.

[0088] The second supporting mechanism 36 is installed on a side of the second support seat 312 close to the second pressing mechanism 35, that is, the second supporting mechanism 36 is arranged opposite to the second pressing mechanism 35. When the eighth driving member 32 drives the second adapter frame 34 to move, the second pressing mechanism 35 can be moved closer to or away from the second supporting mechanism 36 to achieve straightening or bending of the track 80 in the x-axis direction. In the embodiment, the second supporting mechanism 36 can also be provided in three groups, and are evenly spaced along the length direction of the track 80. The three groups of second supporting mechanisms 36 can be movably installed on the second support seat 312 by the second moving mechanism 38, so that the three groups of second supporting mechanisms 36 can be moved along the length direction of the track 80.

[0089] In some specific embodiments, the specific structure of the second supporting mechanism 36 may be the same as the specific structure of the first supporting mechanism 26 , and the specific structure of the second moving mechanism 38 may be the same as the specific structure of the first moving mechanism 28 , which will not be repeated here.

[0090] Furthermore, the second correction unit 30 also includes a second correction detection mechanism 37, which can monitor the deformation of the track 80 in real time during the correction process of the track 80. In the embodiment, there are three groups of second correction detection mechanisms 37, and they are respectively arranged at the corresponding positions of the second supporting mechanism 36. The setting method of the three groups of second correction detection mechanisms 37 is the same as the setting method of the three groups of first correction detection mechanisms 27, and the specific structure of the second correction detection mechanism 37 is the same as the specific structure of the first correction detection mechanism 27, which will not be repeated here. The distance between the two second correction detection mechanisms 37 on both sides can be set to one meter, so that the three groups of second correction detection mechanisms 37 can indirectly characterize the straightness of the unit length of the track 80.

[0091] In this embodiment, a first conveying mechanism 12 is also provided at both the input and output ends of the second correction unit 30. The support blocks 123 in the two first conveying mechanisms 12 are fixedly connected to the second support base 312. The first conveying rollers 122 in the two sets of first conveying mechanisms 12 are arranged parallel to the second supporting mechanism 36.

[0092] like Figure 1 As shown, the unloading unit 40 is disposed at the output end of the second calibration unit 30 and can be used to receive the calibrated track 80 for unloading. In some specific embodiments, the unloading unit 40 includes a second supporting mechanism 41 and a second conveying mechanism 42.

[0093] The second support mechanism 41 is provided with multiple groups, which are evenly spaced along the length of the track 80. The second support mechanism 41 is provided with corresponding loading and unloading ends. The loading end of the second support mechanism 41 is located near the output end of the second calibration unit 30 and is used to receive the track 80 output by the second calibration unit 30. Correspondingly, the second support mechanism 41 is also provided with a corresponding pushing assembly 113 and a driving assembly 114, which are used to push the track 80 from the loading end of the second support mechanism 41 to the unloading end. The operator can remove the track 80 at the unloading end.

[0094] In an embodiment, the second conveying mechanism 42 is also provided with multiple groups, and the multiple groups of second conveying mechanisms 42 are spaced apart along the length direction of the track 80. The multiple groups of second conveying mechanisms 42 are provided corresponding to the output end of the second correction unit 30. The second conveying mechanism 42 may include a second conveying roller 421 and a ninth driving member 422, which may be mounted on a corresponding support base. The ninth driving member 422 may be used to drive the second conveying roller 421 to rotate, thereby driving the track 80 to move. In an embodiment, in the vertical direction, the upper surface of the second conveying roller 421 may be slightly higher than the upper surface of the second support mechanism 41 to facilitate the second conveying mechanism 42 to transport the track 80. At the same time, when the track 80 is located on the second conveying mechanism 42, the lower surface of the track 80 is no higher than the height of the end of the pusher assembly 113 used for pushing materials, so that the pusher assembly 113 can push the track 80 to move. In an embodiment, the ninth driving member 422 may be a motor.

[0095] In other embodiments, the second conveyor roller 421 and the ninth drive member 422 may also be floatingly mounted on corresponding support bases via hydraulic cylinders. When transporting the rail 80, the second conveyor roller 421 and the ninth drive member 422 may be raised to a certain height relative to the second support mechanism 41 to disengage the rail 80 from the second support mechanism 41 and prevent the second support mechanism 41 from interfering with the transport of the rail 80. Once the rail 80 has been transported to its proper location, the second conveyor roller 421 may be lowered to place the rail 80 on the second support mechanism 41, allowing the pusher assembly 113 to push the rail 80 from the loading end to the unloading end of the second support mechanism 41.

[0096] Furthermore, a set of second conveying mechanisms 42 is provided between the first correction unit 20 and the second correction unit 30 , which can be used for transportation of the track 80 .

[0097] In the embodiment, the track correction device further includes a hydraulic unit 70 . It is understandable that each hydraulic cylinder in the track correction device can be connected to the hydraulic unit 70 , and the hydraulic unit 70 provides hydraulic power to the hydraulic cylinder.

[0098] It is understood that all electrical components in the track correction equipment can be electrically connected to the main control unit 50, which controls the operation of each component in the track correction equipment. In an embodiment, the main control unit 50 may be equipped with a PLC (Programmable Logic Controller) to achieve automated operation of the track correction equipment. During operation, the operator can also use the main control unit 50 to set various operating parameters of the track correction equipment.

[0099] During operation, the operator can place the track 80 to be calibrated on the loading end 112a of the bracket 112. The pusher assembly 113 then pushes the track 80 to the unloading end 112b of the bracket 112, causing the track 80 to fall onto the first conveying mechanism 12. The first conveying mechanism 12 can lift the track 80 a certain distance to allow the track 80 to separate from the bracket 112. The first support mechanism 11 can move away from the first conveying mechanism 12 to avoid the detection mechanism 13. Subsequently, the detection mechanism 13 can move along the length of the track 80 to detect the straightness of various parts of the track 80, that is, to perform a preliminary straightness inspection of the track 80. After the inspection is completed, the first conveying mechanism 12 can gradually transport the track 80 to the first calibration unit 20 and / or the second calibration unit 30, so that the first calibration unit 20 and / or the second calibration unit 30 can straighten or bend the corresponding positions of the track 80.

[0100] Taking the example of the first correction unit 20 straightening the track 80, the main control unit 50 can control the first supporting mechanism 26 in the first correction unit 20 to adjust its position and adjust the corresponding pressure block 252 and the supporting block 262 to the appropriate position. Subsequently, the main control unit 50 can control the first driving member 23 to move, so as to drive the corresponding pressure block 252 to press down, so as to straighten the track 80. During the straightening process, the first correction detection mechanism 27 can detect the deformation of the track 80 in real time, so that the main control unit 50 can control the movement of the pressure block 252 according to the detection results. During the straightening process, the first conveying roller 122 in the first conveying mechanism 12 moves downward to disengage from the track 80 to avoid interfering with the straightening of the track 80.

[0101] Taking the example of the first correction unit 20 performing top bending on the track 80, the main control unit 50 can control the first supporting mechanism 26 in the first correction unit 20 to adjust its position, and adjust the corresponding pressure block 252 and the supporting block 262 to a suitable position to perform top bending on the track 80. Subsequently, the main control unit 50 can control the first driving member 23 to move, so as to drive the corresponding pressure block 252 to press down, so as to perform top bending on the track 80. Among them, the first correction detection mechanism 27 located on both sides can be used as a reference to calculate the change of the middle first correction detection mechanism 27. The main control unit 50 can control the displacement of the pressure block 252 according to the change to achieve top bending on the track 80. During the top bending, the first correction detection mechanism 27 can perform real-time detection of the deformation of the track 80.

[0102] In the embodiment, the straightening and bending operation process of the second correction unit 30 is the same as the operation process of the first correction unit 20, and will not be repeated here.

[0103] In this embodiment, after a section of track 80 has been straightened or bent, the first conveying mechanism 12 at the corresponding position can move the track 80 to straighten or bend the next section of track 80. After the entire track 80 has been straightened or bent, the first conveying mechanism 12 can transport the track 80 back to the support platform 14, where the inspection mechanism 13 can re-inspect the straightness of the track 80. If the re-inspection passes, the first conveying mechanism 12 and the second conveying mechanism 42 can cooperate to transport the track 80 to the unloading unit 40. The pusher assembly 113 in the unloading unit 40 then pushes the track 80 to the unloading end of the second support mechanism 41 so that the operator can remove the track 80. If a portion of the track 80 still fails the re-inspection, the corresponding portion of the track 80 is re-transferred to the first calibration unit 20 and / or the second calibration unit 30 for corresponding straightening or bending. After the entire track 80 meets the requirements, it can be transported to the unloading unit 40 for unloading.

[0104] In this embodiment, the first and second alignment units 20 and 30 can perform two-dimensional straightening and top bending on the track 80. This allows for alignment and top bending of the track 80 in multiple directions, avoiding the time-consuming process of repeatedly flipping the track 80 during operation, thereby improving work efficiency.

[0105] The embodiment further provides a track production line, which may include the track correction device provided in the embodiment. The track correction device can straighten or bend the track 80.

[0106] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
