Description

Technical Field

[0001] This application relates to the technical field of rail processing, and particularly to a rail correction device and a rail production line. Background Art

[0002] During the production process of railway tracks, the improvement of straightening and bending efficiency directly affects the production capacity of products. However, in the existing production process, all products need to go through the entire process of the rail correction equipment, resulting in low overall production efficiency and low production capacity of the railway tracks. Summary of the Invention

[0003] This application provides a rail correction device and a rail production line, which separately process qualified products and unqualified products to improve production efficiency and production capacity.

[0004] To solve the above problems, this application provides:

[0005] A rail correction device, comprising a feeding unit, a correction unit, a first discharging unit, a second discharging unit and a detection unit;

[0006] The feeding unit and the first discharging unit are arranged at the input end of the correction unit, and the feeding unit and the first discharging unit are arranged in parallel;

[0007] The second discharging unit is arranged at the output end of the correction unit;

[0008] The detection unit is arranged between the feeding unit and the first discharging unit, and the detection unit is used to detect the straightness of the rail.

[0009] In addition, this application also provides a rail production line, comprising the above-mentioned rail correction device.

[0010] The beneficial effects of this application are as follows: This application proposes a rail correction device and a rail production line, and the rail production line includes the rail correction device. The rail correction device includes a feeding unit, a correction unit, a first discharging unit, a second discharging unit and a detection unit; among them, the feeding unit and the first discharging unit are arranged at the input end of the correction unit and are arranged in parallel. The second discharging unit is arranged at the output end of the correction unit. The detection unit is arranged between the feeding unit and the first discharging unit and is used to detect the straightness of the rail.

[0011] During the operation process, the track can be loaded by the loading unit, and the straightness of the track can be initially inspected by the inspection unit. When the straightness of the track is qualified, the track can be directly unloaded by the first unloading unit arranged in parallel, so that the track does not need to pass through the correction unit to reach the second unloading unit for unloading, thus saving the corresponding operation time. When the straightness of the track is unqualified, it can be corrected by the correction unit and then unloaded by the second unloading unit. It can be seen that the track correction device provided by this application can avoid all tracks going through the entire process of the track correction device. For qualified products, they can be directly unloaded by the first unloading unit, thereby improving the operation efficiency and production capacity. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0029] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0030] As Figure 2 shown, a Cartesian coordinate system is established, defining the x-axis, y-axis, and z-axis, where the length direction of the track 90 is arranged along the y-axis.

[0031] An embodiment provides a track correction device, which can be used for correcting tracks 90 such as railway tracks. Among them, the correction includes straightening and top bending.

[0032] As Figure 1 and Figure 2 shown, the track correction device includes a feeding unit 10, a correction unit 30, a first discharging unit 20, a second discharging unit 40, and a detection unit 50. Among them, the feeding end element 10 is arranged near the input end of the correction unit 30 for feeding. The second discharging unit 40 is arranged near the output end of the correction unit 30 for discharging. The first discharging unit 20 is arranged near the input end of the correction unit 30 and is arranged in parallel with the feeding unit 10. The detection unit 50 is arranged between the feeding unit 10 and the first discharging unit 20. The detection unit 50 is used to detect the straightness of the track 90, including the initial inspection and re-inspection of the straightness of the track 90.

[0033] During the operation process, the track 90 can be placed on the feeding unit 10 for feeding. The detection unit 50 can perform an initial inspection on the straightness of the track 90 to confirm whether the straightness of each part of the track 90 is qualified. When the straightness of each part of the track 90 is qualified, the track 90 can be directly discharged by the first discharging unit 20 without passing through the correction unit 30. When there are parts with inappropriate straightness on the track 90, the track 90 can enter the correction unit 30, and the correction unit 30 can straighten or top bend the corresponding parts of the track 90 to make the overall straightness of the track 90 qualified. After the correction is completed, the track 90 is discharged by the second discharging unit 40. It can be seen that the track correction device provided by the present application can separately process qualified and unqualified tracks 90, enabling the qualified tracks 90 to be directly discharged through the first discharging unit 20, avoiding wasting time by passing through the correction unit 30 again, thereby improving the operation efficiency and production capacity.

[0034] As Figure 1 and Figure 2 shown, the track correction device further includes a control unit 70. The feeding unit 10, the first discharging unit 20, the correction unit 30, the second discharging unit 40, and the detection unit 50 are all electrically connected to the control unit 70, so that the control unit 70 can control and coordinate the work of other units.

[0035] In the embodiment, the loading unit 10 includes a first loading end 10a and a first unloading end 10b. The first unloading end 10b is disposed close to the first unloading unit 20 and corresponds to the input end of the calibration unit 30.

[0036] As Figure 2 、 Figure 4 and Figure 5 shown, the loading unit 10 includes multiple groups of first support components 11. The multiple groups of first support components 11 can be evenly spaced along the length direction of the track 90. The multiple groups of first support components 11 are arranged in parallel and can support various parts of the track 90. In the embodiment, the structures of the multiple groups of first support components 11 are the same, and one of them will be introduced below.

[0037] The first support component 11 includes a support column 111 and a bracket 112. The bracket 112 has a certain length, extends from the first loading end 10a to the first unloading end 10b, and is perpendicular to the length direction of the track 90. The support column 111 is used to support the bracket 112, and the bracket 112 is used to support the track 90.

[0038] A first pusher component 12 and a first driving component 13 are provided on any one of the first support components 11. The first pusher component 12 is slidably mounted on the bracket 112. The first driving component 13 is connected to the first pusher component 12 to drive the first pusher component 12 to move along the length direction of the bracket 112. During loading, the operator can place the track 90 at one end of the bracket 112 close to the first loading end 10a, and then the first driving component 13 can drive the first pusher component 12 to move to push the track 90 from the first loading end 10a to the first unloading end 10b to achieve loading.

[0039] The first pusher component 12 includes a sliding seat 121 and a lever 122. The sliding seat 121 is connected to the first driving component 13. One end of the lever 122 away from the first unloading end 10b is hinged to the sliding seat 121, and a torsion spring (not shown in the figure) is provided between the lever 122 and the sliding seat 121. One end of the lever 122 away from the hinge can be tilted relative to the sliding seat 121 under the action of the torsion spring, and one end of the lever 122 away from the hinge protrudes from the upper surface of the bracket 112, that is, one surface of the bracket 112 away from the support column 111. Thus, one end of the lever 122 can contact the track 90 to push the track 90 to move, and the end of the lever 122 contacting the track 90 is set as a plane.

[0040] The bracket 112 is provided with a mounting groove 1121 inside, and an opening communicating with the outside is provided on one side of the mounting groove 1121 away from the pillar 111. The first driving assembly 13 and the first pushing assembly 12 are installed in the mounting groove 1121, and one end of the lever 122 can be protruded from the upper surface of the bracket 112 through the opening of the mounting groove 1121.

[0041] The first driving assembly 13 includes an eighth driving member (not shown), a first transmission belt 132 and a first transmission wheel 131. The eighth driving member can be fixedly mounted on one end of the bracket 112 close to the first unloading end 10b, and two first transmission wheels 131 are provided, and are respectively arranged at both ends of the bracket 112. Both first transmission wheels 131 are rotatably mounted on the bracket 112. Specifically, the first transmission 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 transmission wheel 131 close to the first unloading end 10b, and the first transmission belt 132 is transmission-connected between the two first transmission wheels 131. The slide 121 is fixedly connected to the first transmission belt 132. Therefore, under the drive of the eighth driving member, the first transmission belt 132 can be moved, thereby driving the first pushing assembly 12 to move back and forth, so as to realize the pushing action and reset of the first pushing assembly 12. The first transmission belt 132 and the first transmission wheel 131 may be meshed and connected via meshing teeth, thereby preventing slippage between the first transmission belt 132 and the first transmission wheel 131. In the embodiment, the eighth driving member may be a motor.

[0042] In other embodiments, the first transmission belt 132 and the first transmission wheel 131 may also be a combination of a belt and a pulley to achieve an anti-slip effect through friction.

[0043] A first reset detection member 14 is also provided on any first support assembly 11, which is used to detect the action of the first push assembly 12, including pushing and resetting, so as to prepare for the next push. Specifically, the first reset detection member 14 can be a plate-shaped structure, and the first reset detection member 14 is fixedly installed on one end of the bracket 112 close to the first feeding end 10a, and the first reset detection member 14 is fixedly installed on one side of the opening of the mounting groove 1121. When the lever 122 is in a natural state, the end of the lever 122 away from the hinge can protrude from the plane where the first reset detection member 14 is located, so that when the lever 122 passes through the first reset detection member 14, it can touch the first reset detection member 14, thereby triggering the first reset detection member 14 to generate a corresponding signal. A gap is provided between the bottom surface of the first reset detection member 14 and the upper surface of the slide 121. When the lever 122 flips and abuts against the end of the slide 121 close to the first feeding end 10a, the gap should allow the lever 122 to pass. In the embodiment, a wire box 141 is fixedly disposed on one side of the bracket 112 for protecting the wires connected to the first reset detection member 14 .

[0044] When it is necessary to push the track 90, the first pusher assembly 12 is driven by the first driving assembly 13 to pass through the first reset detection member 14. The first reset detection member 14 abuts against the lower surface of the lever 122. Under the action of the first reset detection member 14, the lever 122 flips towards one end of the first loading end 10a. After the first pusher assembly 12 passes through the first reset detection member 14, the lever 122 flips and resets towards one end close to the first unloading end 10b. When the lever 122 touches the track 90, the front end face of the lever 122 can completely fit on the surface of the track 90, thereby pushing the track 90 to move.

[0045] When the first pusher assembly 12 is reset, the lever 122 can rotate towards the inside of the slide base 121 under the extrusion of the first reset detection member 14 so as to retract into the slide base 121 for passing through the first reset detection member 14. At the same time, the lever 122 will trigger the first reset detection member 14, indicating that the first pusher assembly 12 has moved to one end of the bracket 112 close to the first loading end 10a, and the eighth driving member can stop operating. In the embodiment, the first reset detection member 14 can be a contact switch. It can be understood that during the reset process of the first pusher assembly 12, when the first reset detection member 14 is triggered, a certain delay time can be set when the control unit 70 controls the eighth driving member to stop operating, so that the lever 122 completely disengages from the first reset detection member 14, avoiding the long-term mutual extrusion state between the first reset detection member 14 and the lever 122 to protect the first reset detection member 14 and the lever 122.

[0046] In some other embodiments, the first reset detection member 14 can also be a non-contact sensor, such as an infrared sensor, a Hall sensor, etc. It can be understood that when the first reset detection member 14 is a Hall sensor, a corresponding magnetic member such as a magnet can be arranged on the first pusher assembly 12 to trigger the Hall sensor.

[0047] In some other embodiments, the lever 122 can also be controlled by a motor to tilt or retract into the slide base 121.

[0048] In the embodiment, the loading unit 10 further includes a first moving component 15 for driving a plurality of groups of first supporting components 11 to slide. Specifically, the first moving component 15 includes a first sliding plate 151, a first slide rail 152, and a ninth driving member (not shown in the figure). The first sliding plate 151 is slidably mounted on the first slide rail 152, and the first slide rail 152 is fixedly arranged. In the embodiment, the first slide rail 152 can be fixedly mounted on the ground. The extending direction of the first slide rail 152 is perpendicular to the length direction of the rail 90. The strut 111 of the first supporting component 11 can be fixedly mounted on the first sliding plate 151. The ninth driving member is used to drive the first sliding plate 151 to slide along the first slide rail 152 to approach or move away from the input end of the first blanking unit 20, that is, to drive the first supporting component 11 to approach or move away from the first blanking unit 20.

[0049] As Figure 1 and Figure 2 As shown, in the embodiment, the rail alignment device further includes a transportation unit 60 for transporting the rail 90 to feed the rail 90 into or out of the alignment unit 30. Specifically, the transportation direction of the transportation unit 60 for the rail 90 is set along the length direction of the rail 90. Specifically, the transportation unit 60 includes a first transmission component 61 and a second transmission component 62, and a plurality of groups are provided for both the first transmission component 61 and the second transmission component 62. A plurality of groups of the first transmission components 61 are arranged corresponding to the input end of the alignment unit 30, and the first transmission component 61 is arranged close to the first loading end 10a of the loading unit 10. The plurality of groups of the first transmission components 61 are spaced apart along the length direction of the rail 90, and the plurality of groups of the first transmission components 61 and the plurality of groups of the first supporting components 11 are arranged in an interleaved manner.

[0050] During loading, the first moving component 15 can drive the first supporting component 11 to move in a direction approaching the first transmission component 61, so that one end of the first supporting component 11 close to the first blanking end 10b extends to the transmission path of the first transmission component 61. After the rail 90 is pushed to the first blanking end 10b, it can be received by the first transmission component 61 to facilitate the first transmission component 61 to transport the rail 90.

[0051] As Figure 3As shown, the first transmission component 61 includes a sixth driving member 614 and a first conveying roller 615. The sixth driving member 614 is used to drive the first conveying roller 615 to rotate. The axis of the first conveying roller 615 is arranged along the horizontal direction and is perpendicular to the length direction of the track 90. In the embodiment, the first transmission component 61 further includes a first support block 611, a floating plate 612, and a tenth driving member (not shown in the figure). The sixth driving member 614 is fixedly installed on the floating plate 612. The floating plate 612 is floatingly installed on the first support block 611 through the tenth driving member. During use, the tenth driving member can drive the floating plate 612 to perform a lifting action, so that the first conveying roller 615 contacts or moves away from the track 90. When the first conveying roller 615 rises and contacts the track 90, the track 90 can be separated from the first support component 11, facilitating the first transmission component 61 to transport the track 90. When the first conveying roller 615 descends and moves away from the track 90, the first conveying roller 615 will no longer act on the track 90. In the embodiment, a fourth guiding rod 613 is further connected between the first support block 611 and the floating plate 612. One end of the fourth guiding rod 613 can be fixedly connected to the floating plate 612, and the other end of the fourth guiding rod 613 is telescopically installed on the first support block 611, thereby guiding the lifting of the floating plate 612 and preventing the floating plate 612 from tilting during lifting. In some specific embodiments, the sixth driving member 614 can be a motor with an encoder, and the tenth driving member can be a hydraulic cylinder.

[0052] In other embodiments, the sixth driving member 614 can also be a hydraulic cylinder combined with a gear transmission assembly and a clutch to drive the first conveying roller 615 to rotate. The tenth driving member can also be an electric push rod, a cylinder, a motor combined with a lead screw and other structures to drive the floating plate 612 to lift.

[0053] Such as Figure 2As shown, in the embodiment, the detection unit 50 includes a sliding carriage 51, a support platform 52, and at least three groups of laser detectors (not shown in the figure). Among them, the support platform 52 is connected to the input end of the calibration unit 30, and the support platform 52 extends along the length direction of the track 90. Multiple groups of first transmission components 61 located at the input end of the calibration unit 30 are all installed on the support platform 52, and the feeding unit 10 and the first discharging unit 20 are respectively arranged on both sides of the support platform 52. The sliding carriage 51 is slidably installed on the support platform 52. A fourth slide rail 521 cooperating with the sliding carriage 51 is provided on the support platform 52, and the fourth slide rail 521 is arranged along the length direction of the support platform 52, that is, the sliding carriage 51 can move along the length direction of the track 90. The sliding carriage 51 can be in the shape of a portal frame, and the opening width inside the sliding carriage 51 is greater than the width of the first transmission component 61, that is, the dimension of the first transmission component 61 in the x-axis direction, so that the sliding carriage 51 can smoothly pass by the first transmission component 61. At least three groups of laser detectors are respectively arranged on three inner side walls of the sliding carriage 51. In this embodiment, three laser detectors are provided. One laser detector is arranged on the inner wall of the top of the sliding carriage. The other two laser detectors are respectively arranged on two inner walls of the side of the sliding carriage 51 and are symmetrically arranged. During detection, the sliding carriage 51 can move along the length direction of the track 90, so that the straightness of each part of the track 90 can be detected in two dimensions by the three laser detectors, that is, the z-axis direction and the x-axis direction. During detection, the first moving component 15 can drive the first support component 11 away from the first transmission component 61 to prevent the first support component 11 from interfering with the movement of the sliding carriage 51.

[0054] In some other embodiments, the number of laser detectors can also be set to four groups, five groups, six groups, etc.

[0055] It can be understood that a twelfth driving member (not shown in the figure) for driving the sliding carriage 51 to slide can also be provided inside the support platform 52, and the twelfth driving member can be a motor. The output shaft of the twelfth driving member is connected to a lead screw, and a nut sleeve (not shown in the figure) cooperating with the lead screw can be provided on the sliding carriage 51 and other structures to achieve threaded engagement connection. At the same time, the sliding carriage 51 does not rotate synchronously with the lead screw under the limiting action of the fourth slide rail 521, so as to realize the linear movement of the sliding carriage 51.

[0056] In the embodiment, the initial position of the sliding carriage 51 should be between the rail 90 and the calibration unit 30, that is, the initial position is at the front end of the rail 90. During the detection process, the end position of the sliding carriage 51 should be on the side of the rail 90 away from the calibration unit 30 and at a certain distance from the end of the rail 90. Thus, when detecting the straightness of the rail 90 through the laser detector, it is convenient to judge whether to start the detection and whether the detection is 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. At the same time, the initial position information of the rail 90 can also be accurately obtained to facilitate controlling the moving distance of the rail 90 each time during subsequent operations. It can be understood that the initial position of the sliding carriage 51 is fixed, that is, after each detection by the detection unit 50 is completed, the sliding carriage 51 is reset to the initial position.

[0057] As Figure 1 and Figure 2 shown, the first blanking unit 20 includes a second loading end 20a and a second blanking end 20b, and the second loading end 20a is arranged close to the first blanking end 10b of the loading unit 10. The first blanking unit 20 includes multiple groups of second support components 21, and the multiple groups of second support components 21 are arranged at intervals along the length direction of the rail 90. In some specific embodiments, the number of the second support components 21 can be equal to the number of the first support components 11 and are arranged in one-to-one correspondence. The structure of the second support component 21 is the same as that of the first support component 11.

[0058] At the same time, a second pushing component 22, a second driving component 23 and a second reset detection component 24 are also arranged on any one of the second support components 21. The structure and installation method of the second pushing component 22 can be the same as those of the first pushing component 12, the structure and installation method of the second driving component 23 can be the same as those of the first driving component 13, and the structure of the second reset detection component 24 can be the same as that of the first reset detection component 14, which will not be elaborated here. The second reset detection component 24 is arranged at one end of the second support component 21 close to the second loading end 20a. The second driving component 23 can drive the second pushing component 22 to move to push the rail 90 to move, and the second reset detection component 24 can detect the movement of the second pushing component 22.

[0059] In the embodiment, the first blanking unit 20 further includes a second moving component 25 for driving multiple groups of second support components 21 to move. Specifically, it can make the second support components 21 approach or move away from the loading unit 10. Correspondingly, the structure and installation method of the second moving component 25 can be the same as those of the first moving component 15, which will not be elaborated here.

[0060] It can be understood that when the detection unit 50 detects the straightness of the track 90, the second moving component 25 can drive the second support component 21 to move away from the support table 52 so that the second support component 21 can avoid the sliding frame 51. When the straightness of the track 90 is qualified during the initial inspection, the second moving component 25 can drive the second support component 21 to move towards the support table 52, and the end of the second support component 21 close to the second loading end 20a extends to the transmission path of the first transmission component 61. Subsequently, the first conveying roller 615 can be lowered so that the track 90 falls on the second support component 21, and then the track 90 can be pushed to the second unloading end 20b by the second pushing component 22 for unloading.

[0061] Further, as Figure 2 shown, the correction unit 30 includes a first correction mechanism 31 and a second correction mechanism 32 arranged in sequence. Among them, the input end of the first correction mechanism 31 is arranged close to the loading unit 10, and the input end of the first correction mechanism 31 is the input end of the correction unit 30. The output end of the first correction mechanism 31 is arranged close to the input end of the second correction mechanism 32, and the output end of the second correction mechanism 32 is arranged close to the second unloading unit 40. The output end of the second correction mechanism 32 is the output end of the correction unit 30.

[0062] Among them, the correction direction of the first correction mechanism 31 is perpendicular to the correction direction of the second correction mechanism 32. The correction directions of the first correction mechanism 31 and the second correction mechanism 32 are both perpendicular to the length direction of the track 90. Thus, the track correction device can realize the correction of the track 90 in two dimensions, so that it is no longer necessary to repeatedly flip the track 90 to realize the correction of different positions during the correction process of the track 90, and thus the correction efficiency of the track 90 can be improved, that is, the operation efficiency can be improved.

[0063] As Figure 6 、 Figure 8 and Figure 9 shown, the correction direction of the first correction mechanism 31 is arranged along the z-axis. The first correction mechanism 31 includes a housing assembly 311, a first driving member 312, a first pressing assembly 314 and a second pressing assembly 315. Among them, the housing assembly 311 includes a frame 3111 and a support base 3112. The frame 3111 can be in an inverted L shape, and the horizontal section of the frame 3111 can be arranged corresponding to the upper part of the support base 3112. In the embodiment, the first driving member 312 is fixedly installed in the horizontal section of the frame 3111. The first pressing assembly 314 is connected to the output shaft of the first driving member 312. The second pressing assembly 315 is installed on the side of the support base 3112 close to the first driving member 312. During use, the first driving member 312 can drive the first pressing assembly 314 to move up and down to approach or move away from the second pressing assembly 315. In the embodiment, the first driving member 312 can be selected as a hydraulic cylinder.

[0064] In some other embodiments, the first driving member 312 may also be selected from structures such as a motor, an electric push rod, a cylinder, etc. to drive the first pressing assembly 314 to move up and down.

[0065] The first pressing assembly 314 may be connected to the output shaft of the first driving member 312 through an adapter bracket 313. Specifically, the adapter bracket 313 is fixedly connected to the output shaft of the first driving member 312, and the first pressing assembly 314 is installed on one side of the adapter bracket 313 close to the support base 3112. In the embodiment, three groups of the first pressing assemblies 314 are provided and are evenly spaced along the length direction of the adapter bracket 313, and the length direction of the adapter bracket 313 is arranged along the length direction of the track 90. During use, the first driving member 312 can drive the adapter bracket 313 to move up and down to drive the three groups of the first pressing assemblies 314 to move up and down simultaneously.

[0066] In some other embodiments, the number of the first pressing assemblies 314 may also be set to two groups, five groups, six groups, seven groups, etc., and no specific limitation is made here.

[0067] In the embodiment, the first calibration mechanism 31 further includes a wire rope encoder 318 for detecting the displacement amount when the adapter bracket 313 moves up and down, and further reflecting the lifting displacement amount of the first pressing assembly 314. The wire rope encoder 318 can be fixedly installed on the first driving member 312.

[0068] Two groups of symmetric guiding assemblies are further arranged between the adapter bracket 313 and the frame 3111 for guiding the lifting action of the adapter bracket 313 to prevent the adapter bracket 313 from tilting and ensure the precise movement of the first pressing assembly 314. Specifically, the guiding assembly includes a first guiding rod 3131 and a guiding sleeve 3111a, and the guiding sleeve 3111a can be fixedly installed on the outer side wall of the frame 3111. One end of the first guiding rod 3131 can be fixedly connected to the adapter bracket 313, and the other end of the first guiding rod 3131 can pass through the guiding sleeve 3111a at the corresponding position. The diameter of the first guiding rod 3131 is equal to the inner diameter of the guiding sleeve 3111a, and the first guiding rod 3131 can slide smoothly relative to the guiding sleeve 3111a.

[0069] The structures of the three groups of the first pressing assemblies 314 are the same, and one of them will be introduced below.

[0070] The first top pressing assembly 314 includes a first mounting bracket 3141, a first pressing head 3143, and a second driving member 3142. Among them, the first mounting bracket 3141 is fixedly mounted on the adapter bracket 313. The first pressing head 3143 is slidably mounted on the side of the first mounting bracket 3141 away from the adapter bracket 313. A first sliding groove 3141a for the first pressing head 3143 to slide is provided on the first mounting bracket 3141. In the embodiment, the first sliding groove 3141a can be a dovetail groove. Correspondingly, the shape of the side of the first pressing head 3143 close to the first mounting bracket 3141 can match the first sliding groove 3141a, so that in the vertical direction, the first pressing head 3143 can be limited in the first sliding groove 3141a to prevent the first pressing head 3143 from detaching from the first mounting bracket 3141. The extending direction of the first sliding groove 3141a is arranged along the horizontal direction and is perpendicular to the length direction of the track 90, that is, arranged along the x-axis direction. In the embodiment, the side of the first pressing head 3143 close to the second top pressing assembly 315 protrudes from the lower surface of the first mounting bracket 3141, that is, one surface of the first mounting bracket 3141 close to the second top pressing assembly 315.

[0071] The second driving member 3142 can be a rodless hydraulic cylinder. The second driving member 3142 and the first pressing head 3143 can be fixedly connected through a first connecting plate 3145. The second driving member 3142 is slidably mounted on one side of the first mounting bracket 3141 through a second guiding rod 3144. Both ends of the second guiding rod 3144 are fixedly mounted on the side wall of the first mounting bracket 3141. The second driving member 3142 is sleeved on the second guiding rod 3144 and can slide along the second guiding rod 3144. The second guiding rod 3144 is arranged parallel to the first sliding groove 3141a.

[0072] As Figure 8 and Figure 9 shown, the second top pressing assembly 315 can be movably mounted on the side of the support seat 3112 close to the first top pressing assembly 314 through a third moving assembly 316. Specifically, the third moving assembly 316 includes a mounting plate 3161, a transmission rod 3162, a second transmission wheel 3163, and a fourth driving member 3164. Among them, the mounting plate 3161 is fixedly mounted on the support seat 3112, and the length direction of the mounting plate 3161 is arranged along the length direction of the track 90. The transmission rod 3162 is rotatably mounted on the mounting plate 3161, and the transmission rod 3162 is parallel to the length direction of the mounting plate 3161. Both ends of the transmission rod 3162 can be rotatably connected to the mounting plate 3161 through bearings (not shown in the figure). A second transmission wheel 3163 is fixedly connected to one end of the transmission rod 3162, and the fourth driving member 3164 and the second transmission wheel 3163 can be drivingly connected through a second transmission belt (not shown in the figure).

[0073] In the embodiment, the fourth driving member 3164 can be fixedly installed at one end of the support base 3112 close to the second transmission wheel 3163, so as to facilitate the connection between the fourth driving member 3164 and the second transmission wheel 3163. The second transmission wheel 3163 and the second transmission belt can be connected by meshing teeth, so as to avoid slipping between the second transmission wheel 3163 and the second transmission belt and achieve stable transmission. In the embodiment, the transmission rod 3162 can be selected as a lead screw, and a nut sleeve (not shown in the figure) cooperating with the transmission rod 3162 can be arranged on the second pressing assembly 315 to realize the threaded fit connection between the second pressing assembly 315 and the transmission rod 3162. In some specific embodiments, the transmission rod 3162 can be embedded in the through groove of the mounting plate 3161. Correspondingly, the nut sleeve connected to the second pressing assembly 315 extends into the through groove of the mounting plate 3161 to be connected to the transmission rod 3162. The second pressing assembly 315 is supported on one side of the mounting plate 3161 close to the first pressing assembly 314. Thus, the second pressing assembly 315 will not rotate following the transmission rod 3162. When the fourth driving member 3164 drives the transmission rod 3162 to rotate, the second pressing assembly 315 can be driven to move along the length direction of the transmission rod 3162. In the embodiment, the fourth driving member 3164 can be selected as a motor.

[0074] In the embodiment, there are also three groups of the second pressing assemblies 315, which are equal in number to the first pressing assembly 314. The three groups of second pressing assemblies 315 can be arranged at equal intervals along the length direction of the mounting plate 3161. The structures of the three groups of second pressing assemblies 315 are the same, and one of them will be introduced below.

[0075] Specifically, the second pressing assembly 315 includes a second mounting frame 3151, a second pressing head 3153, and a third driving member 3152. The nut sleeve can be fixedly arranged on one side of the second mounting frame 3151 close to the mounting plate 3161, that is, the second mounting frame 3151 is mounted on the third moving assembly 316. The second pressing head 3153 is slidably mounted on one side of the second mounting frame 3151 close to the first pressing assembly 314. A second sliding groove 3151a for mounting the second pressing head 3153 is arranged on the second mounting frame 3151, and the second pressing head 3153 is slidably arranged in the second sliding groove 3151a. The second sliding groove 3151a can also be in the structure of a dovetail groove. Correspondingly, the shape of the second pressing head 3153 for connecting the position of the second sliding groove 3151a can match the second sliding groove 3151a to limit the second pressing head 3153 on the second mounting frame 3151 in the vertical direction and prevent the second pressing head 3153 from separating from the second mounting frame 3151. One side of the second pressing head 3153 close to the first pressing assembly 314 protrudes from the upper surface of the second mounting frame 3151, that is, one surface of the second mounting frame 3151 close to the first pressing assembly 314. The extending direction of the second sliding groove 3151a is arranged along the horizontal plane and is perpendicular to the extending direction of the transmission rod 3162.

[0076] In the embodiment, the third driving member 3152 can be selected as a rodless hydraulic cylinder. The third driving member 3152 is fixedly connected to the second indenter 3153 through a second connecting plate 3155. The third driving member 3152 is slidably mounted on one side of the second mounting bracket 3151 through a third guide rod 3154. The third guide rod 3154 can be arranged parallel to the second chute 3151a, and both ends of the third guide rod 3154 are fixedly connected to the side wall of the second mounting bracket 3151. The third driving member 3152 is slidably sleeved on the third guide rod 3154, so that the third driving member 3152 can drive the second indenter 3153 to slide along the second chute 3151a.

[0077] As Figure 12 and Figure 13 shown, during use, the positions of the three groups of second pressing assemblies 315 in the y-axis direction can be adjusted according to the positions on the rail 90 that need to be corrected. At the same time, the second indenter 3153 in any one or two groups of the second pressing assemblies 315 can be selected to support the rail 90. Correspondingly, the second indenters 3153 in the other groups of the second pressing assemblies 315 can move along the second chute 3151a to a position away from the rail 90 for avoidance. Correspondingly, two or one group of the first pressing assemblies 314 at the corresponding positions can also be selected, and their first indenters 3143 are made to correspond to the position of the rail 90. Correspondingly, the first indenters 3143 in the other groups of the first pressing assemblies 314 move along the first chute 3141a to a position away from the rail 90 for avoidance. The first pressing assembly 314 and the second pressing assembly 315 can cooperate to straighten or bend the corresponding position of the rail 90.

[0078] Furthermore, as Figures 9 to 11 shown, the first correction mechanism 31 further includes a correction detection assembly 317 for detecting the deformation amount of the rail 90 during the bending or straightening process. In the embodiment, three groups of correction detection assemblies 317 are provided, and the three groups of correction detection assemblies 317 are respectively arranged at the positions of the three groups of second pressing assemblies 315. Specifically, one group of correction detection assemblies 317 is fixedly arranged at the end of the middle group of second pressing assemblies 315 and is arranged corresponding to the midline of this group of second pressing assemblies 315, that is, corresponding to the midline of the second chute 3151a. The other two groups of correction detection assemblies 317 are respectively arranged on the sides of the other two groups of second pressing assemblies 315 and are symmetrically arranged with respect to the middle group of correction detection assemblies 317. The distance between the two correction detection assemblies 317 on both sides can be set to one meter, so that the three groups of correction detection assemblies 317 can indirectly represent the straightness of the unit length of the rail 90. In the embodiment, the structures of the three groups of correction detection assemblies 317 are the same, and one of them will be introduced below.

[0079] The calibration detection component 317 includes an adapter plate 3172, a measuring rod 3171, an elastic member 3178, a fifth driving member 3177, and a grating detection component (not shown in the figure). The adapter plate 3172 is fixedly installed on the corresponding second mounting bracket 3151. One end of the fifth driving member 3177 is fixedly connected to one end of the adapter plate 3172, and the other end of the fifth driving member 3177 is fixedly connected to a fixed block 3173, and the fixed block 3173 is fixedly connected to the other end of the adapter plate 3172.

[0080] The measuring rod 3171 is arranged parallel to the second sliding groove 3151a, that is, the measuring rod 3171 is arranged along the x-axis direction. The measuring rod 3171 is slidably arranged relative to the fixed block 3173. Specifically, one end of the measuring rod 3171 is fixedly connected with a connecting rod 3175, and a second slide rail 3176 is fixedly arranged on one side of the connecting rod 3175 close to the fixed block 3173. Correspondingly, a slider 3174 that cooperates with the second slide rail 3176 is fixedly arranged on the fixed block 3173. The second slide rail 3176 can slide relative to the slider 3174, and the sliding direction of the second slide rail 3176 relative to the slider 3174 is parallel to the calibration direction of the first calibration mechanism 31, that is, along the z-axis. Thus, the synchronous lifting movement of the second slide rail 3176 and the measuring rod 3171 can be realized.

[0081] The connecting rod 3175 is fixedly connected to the output shaft of the fifth driving member 3177. The fifth driving member 3177 can drive the connecting rod 3175 to move up and down, and further drive the measuring rod 3171 to lift. One end of the elastic member 3178 is fixedly connected to the fixed 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. At the same time, the elastic member 3178 is in a stretched state. Thus, under the elastic force of the elastic member 3178, the measuring rod 3171 can be driven to move upward.

[0082] In the embodiment, the grating detection component may include a scale grating and a grating reading head. The scale grating is arranged along the second slide rail 3176, and the grating reading head is arranged on one side of the slider 3174 close to the second slide rail 3176. Thus, the moving distance of the second slide rail 3176 can be measured by the grating detection component.

[0083] In use, when adjusting the position of the rail 90, the fifth driving member 3177 can overcome the elastic force of the elastic member 3178 to drive the measuring rod 3171 to move downward by a certain distance, so that the measuring rod 3171 is separated from the rail 90, avoiding problems such as friction and collision between the rail 90 and the measuring rod 3171 during the movement of the rail 90. After the rail 90 moves into place, the fifth driving member 3177 can be in a failure state, and under the action of the elastic force of the elastic member 3178, the measuring rod 3171 is abutted against the side of the rail 90 close to the second pressing assembly 315. It can be understood that the measuring rod 3171 abuts against the lower surface of the rail 90. Thus, during the straightening or bending process, as the rail 90 deforms, it can drive the corresponding measuring rod 3171 to move, and then the moving distance of the measuring rod 3171, that is, the amount of deformation of the rail 90, can be detected by the grating detection assembly. Among them, the setting of the elastic member 3178 can make the measuring rod 3171 always abut against the surface of the rail 90. In the embodiment, the fifth driving member 3177 can be a hydraulic cylinder. The elastic member 3178 can be a spring.

[0084] In other embodiments, the fifth driving member 3177 can also be selected as a cylinder or other structures. The elastic member 3178 can also be selected as a shrapnel, an elastic rope or other structures.

[0085] In the embodiment, a set of first transmission components 61 are arranged at both the input end and the output end of the first correction mechanism 31, which can be used for the conveying of the rail 90. The first support blocks 611 in the two sets of first transmission components 61 can be fixedly connected to the support base 3112.

[0086] As Figure 2 、 Figure 6 and Figure 7 shown, further, the correction unit 30 further includes a base mechanism 33, and the first correction mechanism 31 is installed on the base mechanism 33. The base mechanism 33 includes a base 331, and the first correction mechanism 31 can be slidably installed on the base 331. The sliding direction of the first correction mechanism 31 relative to the base 331 is perpendicular to both the length direction of the rail 90 and the correction direction of the first correction mechanism 31, that is, arranged along the x-axis direction. Specifically, a second sliding plate 332 is fixedly connected to the side of the housing assembly 311 close to the base 331, and a third slide rail 3311 cooperating with the second sliding plate 332 is arranged on the base 331. The second sliding plate 332 is slidably connected to the third slide rail 3311, thereby realizing the sliding installation of the first correction mechanism 31 and the base 331.

[0087] In the embodiment, an eleventh driving member (not shown in the figure) is further arranged on the base 331, which is used to drive the second sliding plate 332 to slide along the third slide rail 3311. In some specific embodiments, the eleventh driving member can be selected as a motor, and the output end of the motor can be connected with a lead screw (not shown in the figure), and the lead screw is in threaded fit connection with the second sliding plate 332.

[0088] Furthermore, the base mechanism 33 further includes a protective cover 333. The protective cover 333 covers the side of the base 331 where the third slide rail 3311 is provided to protect the structures such as the third slide rail 3311, the eleventh driving member, and the lead screw located on the base 331, preventing debris from entering and affecting the movement of the first calibration mechanism 31. In the embodiment, the protective cover 333 can be a bellows-type protective cover. The protective cover 333 can be provided in two sections. One end of one section of the protective cover 333 can be fixedly connected to the side of the frame 3111 away from the support base 3112, and the other end can be fixedly connected to the end of the base 331 away from the support base 3112. One end of the other section of the protective cover 333 can be connected to the side of the support base 3112 away from the frame 3111, and the other end can be connected to the end of the base 331 away from the frame 3111. While the first calibration mechanism 31 moves, it drives the protective cover 333 to expand or contract.

[0089] During use, when the second calibration mechanism 32 is required to calibrate the track 90, the base mechanism 33 can drive the first calibration mechanism 31 away from the track 90 to provide space for the deformation of the track 90 and prevent the first calibration mechanism 31 from interfering with the calibration of the track 90.

[0090] As Figure 2 and Figure 14 shown, the structure of the second calibration mechanism 32 is orthogonal to the structure of the first calibration mechanism 31, that is, the second calibration mechanism 32 can be obtained after the first calibration mechanism 31 rotates 90°. The specific structure of the second calibration mechanism 32 will not be elaborated here. The calibration direction of the second calibration mechanism 32 is perpendicular to both the calibration direction of the first calibration mechanism 31 and the length direction of the track 90, that is, the second calibration mechanism 32 can straighten and bend the track 90 in the x-axis direction.

[0091] As Figure 1 and Figure 2 shown, the second blanking unit 40 is arranged close to the output end of the calibration unit 30 and can be used to receive the calibrated track 90 to achieve blanking. In some specific embodiments, the second blanking unit 40 includes a third loading end 40a and a third unloading end 40b. Among them, the third loading end 40a is arranged close to the output end of the calibration unit 30, and correspondingly, the third unloading end 40b is arranged at the far end.

[0092] The second blanking unit 40 includes multiple groups of third support components 41. The multiple groups of third support components 41 are arranged at equal intervals along the length direction of the track 90, thereby supporting various parts of the track 90. The third support components 41 extend from the third loading end 40a to the third unloading end 40b and are perpendicular to the length direction of the track 90. In the embodiment, the structures of the multiple groups of third support components 41 are the same, and one of them will be introduced below.

[0093] On any third support component 41, there is also a corresponding third pusher component 42 and a third driving component 43. The third pusher component 42 is slidably mounted on the third support component 41, and the third driving component 43 is used to drive the third pusher component 42 to move, so as to push the rail 90 from the third loading end 40a to the third unloading end 40b to achieve unloading, and the operator can remove the rail 90 at the third unloading end 40b. Correspondingly, on any third support component 41, there is also a third reset detection component 44 for detecting the action of the third pusher component 42. In the embodiment, the structure and installation method of the third pusher component 42 are the same as those of the first pusher component 12, the structure and installation method of the third driving component 43 are the same as those of the first driving component 13, and the structure and installation method of the third reset detection component 44 are the same as those of the first reset detection component 14, and will not be elaborated here. Among them, the third reset detection component 44 is arranged at one end of the third support component 41 close to the third loading end 40a.

[0094] In the embodiment, multiple groups of second transmission components 62 are arranged corresponding to the output end of the calibration unit 30, that is, arranged in the output direction of the calibration unit 30, and multiple groups of second transmission components 62 are arranged at intervals along the length direction of the rail 90. Multiple groups of second transmission components 62 and multiple groups of third support components 41 are arranged alternately, and the second transmission components 62 are arranged at the third loading end 40a. One end of the third support component 41 close to the third loading end 40a can extend to the transmission path of the second transmission component 62. The structures of multiple groups of second transmission components 62 are the same, and one of them will be introduced below.

[0095] The second transmission component 62 may include a second conveying roller 622, a seventh driving member 621, and a second support block 623. The seventh driving member 621 is fixedly mounted on the second support block 623. The second conveying roller 622 is connected to the output shaft of the seventh driving member 621, and the seventh driving member 621 can drive the second conveying roller 622 to rotate to drive the rail 90 to move. The axis of the second conveying roller 622 is arranged along the horizontal direction and is perpendicular to the length direction of the rail 90. In the embodiment, in the vertical direction, the upper surface of the second conveying roller 622 may be slightly higher than the upper surface of the third support component 41, so as to avoid being blocked by the third support component 41 when the second transmission component 62 transports the rail 90. At the same time, when the rail 90 is located on the second transmission component 62, the lower surface of the rail 90 is not higher than the height of the end of the third pusher component 42 for pushing the material, so as to facilitate the third pusher component 42 to push the rail 90 to move. In the embodiment, the seventh driving member 621 may be a motor.

[0096] In some other embodiments, the second conveying roller 622 and the seventh driving member 621 can also be floatingly mounted on the second support block 623 through a hydraulic cylinder. When transporting the track 90, the second conveying roller 622 and the seventh driving member 621 can be raised by a certain height relative to the third support assembly 41 to disengage the track 90 from the third support assembly 41 and avoid interference of the third support assembly 41 with the transportation of the track 90. After the track 90 is output in place, the second conveying roller 622 can be lowered to place the track 90 on the third support assembly 41, so as to facilitate the third pusher assembly 42 to push the track 90 from the third loading end 40a to the third unloading end 40b.

[0097] Furthermore, a set of second transmission components 62 can be arranged between the first correction mechanism 31 and the second correction mechanism 32 and can be used for transporting the track 90.

[0098] In the embodiment, the track correction device further includes a hydraulic unit 80. It can be understood that each hydraulic cylinder in the track correction device can be connected to the hydraulic unit 80, and the hydraulic unit 80 provides hydraulic power to the hydraulic cylinders.

[0099] It can be understood that each electrical component in the track correction device can be electrically connected to the control unit 70, and the control unit 70 controls the actions of each component in the track correction device. In the embodiment, a PLC (Programmable Logic Controller) controller can be arranged in the control unit 70 to realize the automated operation of the track correction device. During operation, the operator can also set the working parameters of the track correction device through the control unit 70.

[0100] During the operation process, the operator can place the rail 90 at the first loading end 10a of the loading unit 10. Subsequently, the first pusher assembly 12 pushes the rail 90 to the position of the first unloading end 10b, and aligns the rail 90 with the first transmission assembly 61. The first transmission assembly 61 can lift the rail 90 by a certain distance to disengage the rail 90 from the loading unit 10. The loading unit 10 can move away from the first transmission assembly 61 to avoid the detection unit 50. Subsequently, the sliding carriage 51 can move along the length direction of the rail 90 to detect the straightness of each part of the rail 90, that is, to pre-check the straightness of the rail 90. When the straightness of the rail 90 meets the requirements, the first unloading unit 20 moves towards the support table 52, and the second loading end 20a extends into the transmission path of the first transmission assembly 61. The first conveyor roller 615 descends to make the rail 90 fall onto the first unloading unit 20. Subsequently, the second pusher assembly 22 can push the rail 90 from the second loading end 20a to the second unloading end 20b, facilitating the operator to remove the rail 90 to achieve unloading. For the rail with unqualified pre-check, the first transmission assembly 61 can gradually transport the rail 90 into the correction unit 30 for straightening or bending. After the straightening or bending of each part of the same rail 90 is completed, the first transmission assembly 61 can cooperate with the second transmission assembly 62 to transport the rail 90 back above the support table 52. The detection unit 50 re-checks the straightness of the rail 90. When there are still unqualified parts, the corresponding parts of the rail 90 can be re-fed into the correction unit 30 for straightening or bending. When the rail 90 passes the re-check, the first transmission assembly 61 and the second transmission assembly 62 cooperate to transport the rail 90 from above the support table 52 to the third loading end 40a of the second unloading unit 40, and the second unloading unit 40 unloads the rail 90.

[0101] Taking the calibration of the rail 90 by the first calibration mechanism 31 as an example, the control unit 70 can control the second pressing component 315 in the first calibration mechanism 31 to adjust its position, and make the corresponding first pressing head 3143 and second pressing head 3153 adjust to appropriate positions. Subsequently, the control unit 70 can control the first driving member 312 to act to drive the corresponding first pressing head 3143 to press down. Under the cooperative action of the first pressing head 3143 and the second pressing head 3153, the rail 90 is straightened or bent. During the straightening or bending, the calibration detection component 317 can detect the deformation amount of the rail 90 in real time, so that the control unit 70 can control the action of the first pressing head 3143 according to the detection result. During the straightening process, the first conveying roller 615 in the first conveying component 61 moves downward to disengage from the rail 90 to avoid interfering with the straightening of the rail 90. In the embodiment, the straightening and bending action processes of the second calibration mechanism 32 are the same as those of the first calibration mechanism 31, and will not be elaborated here. It can be understood that when the second calibration mechanism 32 calibrates the rail 90, the first conveying roller 615 does not need to disengage from the rail 90.

[0102] In the embodiment, the first calibration mechanism 31 and the second calibration mechanism 32 can straighten and bend the rail 90 in two dimensions, that is, straighten and bend the rail 90 in multiple directions, avoiding wasting time by repeatedly flipping the rail 90 during the operation process, thereby improving work efficiency.

[0103] In the embodiment, a rail production line is also provided, including the rail calibration device provided in the embodiment. The rail calibration device can detect the straightness of the rail 90 and can straighten or bend the unqualified rail 90.

[0104] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application.
