Description
Technical Field
[0001] This utility model relates to the field of track correction technology, and in particular to a track correction device. Background Technology
[0002] The track correction device does not require electrical power to drive it. It only needs to be installed on the track frame to achieve automatic correction. The track moves on two conical rollers of the correction machine. The conical rollers are at a certain angle to the track. When the track deviates, the two conical rollers will bring the track back to the center with minimal force, so that it returns to the predetermined position.
[0003] When using a track alignment device to correct track deviation, multiple track alignment devices need to be installed on the same track frame. This is mainly achieved by using mounting blocks at both ends of the track alignment device to fix it to the track frame. However, the length of the track alignment device is fixed, while the width of different track frames varies, which reduces the practicality of the track alignment device. Utility Model Content
[0004] This utility model proposes a track correction device to address the problem that the length of the track correction device is fixed, while the width of different track frames varies, which reduces the practicality of the track correction device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a track correction device, comprising a base plate, two mounting blocks at each end of the base plate, an adjustment device between the four mounting blocks and the base plate, the adjustment device comprising two sleeves, one side of each of the two mounting blocks being symmetrically fixedly connected to one end of the sleeve, a first extension block being symmetrically fixedly connected to one side of the sleeve, a threaded cylinder being provided on the inner wall of each of the two first extension blocks, a threaded rod being threadedly connected to the inner wall of the threaded cylinder, a second extension block being fixedly connected to the adjacent ends of the two threaded rods, one side of the second extension block being fixedly connected to one side of the base plate, an auxiliary device being provided on one side of the sleeve, an auxiliary frame being fixedly connected to the top of the base plate, auxiliary rollers being symmetrically rotatably connected to both sides of the inner wall of the auxiliary frame, bending plates being symmetrically fixedly connected to both sides of the auxiliary frame, and a conical roller being provided between the bending plate and the auxiliary frame.
[0006] The effect achieved by the above components is as follows: by setting two sleeves, under the action of the threaded rod and the threaded cylinder, the threaded cylinder rotates and the threaded cylinder will extend and retract on the outer surface of the threaded rod. During the extension and retraction process, the threaded cylinder will drive the sleeve to slide synchronously on the outer surface of the base plate. This makes it easy to adjust the distance between the two sleeves, i.e. the width of the track correction device, according to actual needs. This allows the width of the track correction device to be adjusted accordingly based on the width of the track frame, thereby improving the practicality of the track correction device.
[0007] Preferably, bearings are symmetrically fixedly connected to the outer surface of the threaded cylinder, and the outer surface of the bearings is fixedly connected to the inner wall of the first extension block.
[0008] The effect achieved by the above components is that by setting bearings, the friction between the threaded cylinder and the two first extension blocks can be reduced when rotating the threaded cylinder, making it easier to rotate the threaded cylinder.
[0009] Preferably, each of the two threaded cylinders has an operating block fixedly connected to one of its far ends, and the outer surface of the operating block is provided with a protrusion.
[0010] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the threaded cylinder to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.
[0011] Preferably, a slide bar is fixedly connected to one side of the inner wall of the sleeve, and a sliding groove is provided at the bottom of the base plate, with the outer surface of the slide bar slidably connected to the inner wall of the sliding groove.
[0012] The effect achieved by the above components is that, by setting the slider and the groove, when the sleeve slides on the outer surface of the base plate, it will drive the slider to slide synchronously on the inner wall of the groove, which can limit and guide the sleeve.
[0013] Preferably, the outer surface of the threaded rod is threaded with a nut, and one side of the nut abuts against one end of the threaded cylinder.
[0014] The effect achieved by the above components is as follows: by setting the nut and rotating the nut so that one side of the nut abuts against one end of the threaded cylinder, the direction of the threaded rod entering the inner wall of the threaded cylinder can be limited, which helps to prevent the connection between the correction device and the track frame from becoming loose.
[0015] Preferably, the auxiliary device includes a threaded pin, one end of which is threaded into the inner wall of the sleeve, and a rotating block is fixedly connected to the other end of the threaded pin.
[0016] The effect achieved by the above components is as follows: by setting the threaded pin, rotating the rotating block drives the threaded pin to rotate, so that one end of the threaded pin abuts against one side of the base plate, which can provide auxiliary fixation between the base plate and the sleeve, further fix the base plate and the sleeve, and improve the stability of the connection between the track correction device and the track frame.
[0017] Preferably, an auxiliary groove is provided on one side of the base plate, and a rubber strip is fixedly connected to the inner wall of the auxiliary groove, with the threaded pin disposed on one side of the rubber strip.
[0018] The effect achieved by the above components is that by setting the rubber strip, the friction between the threaded pin and the base plate can be increased, making the threaded pin more securely fixed to the base plate and the sleeve.
[0019] Preferably, an elastic rope is fixedly connected to one side of the rotating block, and one end of the elastic rope is fixedly connected to the outer surface of the sleeve.
[0020] The effect achieved by the above components is that by setting an elastic rope, the rotating block and the sleeve can be fixed, which helps to prevent the threaded pin from coming off the inner wall of the sleeve and thus easily getting lost.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting two sleeves, under the action of the threaded rod and the threaded cylinder, the threaded cylinder can drive the sleeve to slide synchronously on the outer surface of the base plate, thereby facilitating the adjustment of the distance between the two sleeves, i.e. the width of the track correction device, according to actual needs. This allows the width of the track correction device to be adjusted accordingly based on the width of the track frame, thereby improving the practicality of the track correction device.

[0029] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a track correction device, including a base plate 1. Two mounting blocks 4 are provided at both ends of the base plate 1. An adjustment device 2 is provided between the four mounting blocks 4 and the base plate 1. The adjustment device 2 includes two sleeves 21. One side of each mounting block 4 is symmetrically fixedly connected to one end of a sleeve 21. A first extension block 22 is symmetrically fixedly connected to one side of each sleeve 21. Threaded cylinders 23 are provided on the inner walls of the two first extension blocks 22. Threaded rods 24 are threadedly connected to the inner walls of the threaded cylinders 23. A second extension block 25 is fixedly connected to the adjacent ends of the two threaded rods 24. One side of the second extension block 25 is fixedly connected to one side of the base plate 1. An auxiliary device 3 is provided on one side of each sleeve 21. An auxiliary frame 5 is fixedly connected to the top of the base plate 1. Auxiliary rollers 6 are symmetrically rotatably connected to both sides of the inner wall of the auxiliary frame 5. Bending plates 7 are symmetrically fixedly connected to both sides of the auxiliary frame 5. A conical roller 8 is provided between the bending plate 7 and the auxiliary frame 5. By setting two sleeves 21... Under the action of the threaded rod 24 and the threaded cylinder 23, the threaded cylinder 23 rotates, and the threaded cylinder 23 will extend and retract on the outer surface of the threaded rod 24. During the extension and retraction process, the threaded cylinder 23 will drive the sleeve 21 to slide synchronously on the outer surface of the base plate 1, so as to facilitate the adjustment of the distance between the two sleeves 21, i.e. the width of the correction device, according to actual needs. This allows the width of the correction device to be adjusted accordingly according to the width of the track frame, which can improve the practicality of the track correction device. The conical roller 8 can rotate between the bending plate 7 and the auxiliary frame 5, and one end of the conical roller 8 is connected to the bending plate 7 by setting bolts. The tilt angle of the conical roller 8 can be adjusted accordingly according to actual needs. When the track deviates from the theoretical center line, the conical roller 8 that abuts against the track will deflect a certain angle around the rotation center in the corresponding direction, thereby generating a lateral friction force perpendicular to the track running direction between the conical roller 8 and the track, so that the track returns to the correct position.
[0030] Reference Figure 2 and Figure 3As shown, bearings 26 are symmetrically fixedly connected to the outer surface of the threaded cylinder 23. The outer surface of the bearings 26 is fixedly connected to the inner wall of the first extension block 22. By setting the bearings 26, the friction between the threaded cylinder 23 and the two first extension blocks 22 can be reduced when rotating the threaded cylinder 23, making it easier to rotate the threaded cylinder 23. An operating block 27 is fixedly connected to the far end of each of the two threaded cylinders 23. The outer surface of the operating block 27 is provided with protrusions. By setting the operating block 27, rotating the operating block 27 can drive the threaded cylinder 23 to rotate. At the same time, the protrusions on the outer surface of the operating block 27 can effectively increase the friction on the outer surface of the operating block 27, which has an anti-slip effect when rotating the operating block 27.
[0031] Reference Figure 2 and Figure 3 As shown, a slide bar 28 is fixedly connected to one side of the inner wall of the sleeve 21, and a groove 29 is provided at the bottom of the base plate 1. The outer surface of the slide bar 28 is slidably connected to the inner wall of the groove 29. By setting the slide bar 28 and the groove 29, when the sleeve 21 slides on the outer surface of the base plate 1, it will drive the slide bar 28 to slide synchronously on the inner wall of the groove 29, which can limit and guide the sleeve 21. A nut 210 is threadedly connected to the outer surface of the threaded rod 24. One side of the nut 210 abuts against one end of the threaded cylinder 23. By setting the nut 210 and rotating the nut 210, one side of the nut 210 abuts against one end of the threaded cylinder 23, which can limit the direction of the threaded rod 24 entering the inner wall of the threaded cylinder 23, which helps to prevent the connection between the correction device and the track frame from becoming loose.
[0032] Reference Figure 4 and Figure 5 As shown, the auxiliary device 3 includes a threaded pin 31. One end of the threaded pin 31 is threaded into the inner wall of the sleeve 21. A rotating block 32 is fixedly connected to one end of the threaded pin 31. By setting the threaded pin 31, rotating the rotating block 32 drives the threaded pin 31 to rotate, so that one end of the threaded pin 31 abuts against one side of the base plate 1, which can provide auxiliary fixation between the base plate 1 and the sleeve 21, further fix the base plate 1 and the sleeve 21, and improve the stability of the connection between the track correction device and the track frame.
[0033] Reference Figure 4 and Figure 5As shown, an auxiliary groove 33 is provided on one side of the base plate 1. A rubber strip 34 is fixedly connected to the inner wall of the auxiliary groove 33. A threaded pin 31 is set on one side of the rubber strip 34. By setting the rubber strip 34, the friction between the threaded pin 31 and the base plate 1 can be increased, making the fixing of the threaded pin 31 between the base plate 1 and the sleeve 21 more stable. An elastic rope 35 is fixedly connected to one side of the rotating block 32. One end of the elastic rope 35 is fixedly connected to the outer surface of the sleeve 21. By setting the elastic rope 35, the rotating block 32 and the sleeve 21 can be fixed, which helps to prevent the threaded pin 31 from detaching from the inner wall of the sleeve 21 and causing it to be easily lost.
[0034] Working principle: Rotating the two operating blocks 27 drives the threaded cylinder 23 to rotate. The threaded cylinder 23 will extend and retract on the outer surface of the threaded rod 24. Under the limit of the slide bar 28 and the slide groove 29, the threaded cylinder 23 will drive the sleeve 21 to slide synchronously on the outer surface of the base plate 1 until the distance between the two sleeves 21, that is, the width of the track correction device, matches the width of the track frame. Then, rotate the nut 210 so that one side of the nut 210 abuts against one end of the threaded cylinder 23. At the same time, rotate the rotating block 32 to drive the threaded pin 31 to rotate so that one end of the threaded pin 31 abuts against the rubber block on one side of the base plate 1. This can provide auxiliary fixation between the base plate 1 and the sleeve 21, and further fix the base plate 1 and the sleeve 21, improving the stability of the connection between the track correction device and the track frame. The width of the track correction device can be adjusted accordingly according to the width of the track frame, which can improve the practicality of the track correction device.
