[0002] In the construction of transportation projects, the precise installation and adjustment of tracks is an important part of ensuring the safe operation of trains. Traditionally, the installation and adjustment of tracks mainly rely on manual operation and simple mechanical tools, which is not only inefficient but also difficult to ensure the high precision and smoothness of the tracks. With the development of rail transportation, the requirements for track installation quality and precision are getting higher and higher, and the traditional track adjustment method can no longer meet the needs of modern engineering.

[0003] The shortcomings of the existing technology are: 1) The traditional track adjustment method mainly relies on manual adjustment, which has poor accuracy and easily leads to unevenness or misalignment at the track joints, affecting the safety and comfort of train operation; 2) Since a large amount of manual operation is required, the track adjustment process is time-consuming, especially in large-scale construction projects, this problem is particularly prominent, greatly delaying the progress of the project; 3) The existing track adjustment equipment cannot flexibly adapt to the complex terrain conditions of the construction site, and the track grabbing is not reliable and convenient enough, and there are limitations.

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0034] like Figure 1-4 As shown, a track adjuster for traffic engineering provided by an embodiment of the present invention includes an inverted U-shaped arm frame 3, a supporting moving assembly is installed at the lower end of the inverted U-shaped arm frame 3, and further includes:

[0035] Adjustment pedestal 5, two adjustment pedestals 5 are slidably mounted on the horizontal part of the inverted U-shaped arm 3, and lateral adjustment components for driving the two adjustment pedestals 5 to move are also mounted on both sides of the inverted U-shaped arm 3, and a mounting platform 7 is provided below the adjustment pedestal 5, and a height adjustment component is installed between the adjustment pedestal 5 and the mounting platform 7, and the height adjustment component is used to drive the mounting platform 7 to rise and fall;

[0036] A top pressure plate 17 is provided in the middle below the mounting platform 7, and a plurality of inverted U-shaped roller frames 22 are adjustable and slidably mounted on the top pressure plate 17, and a top pressure roller 21 is rotatably mounted on the lower side of the inverted U-shaped roller frame 22; a grabbing telescopic cylinder 9 for supporting the top pressure plate 17 and driving the top pressure plate 17 to rise and fall is also installed on the mounting platform 7;

[0037] Side crossbeams 11, a side crossbeam 11 is arranged on each side below the mounting platform 7, bottom supports 10 are fixed at both ends of the side crossbeams 11, the upper ends of the bottom supports 10 are connected and fixed to the mounting platform 7, and a plurality of adjustable sleeves 13 are adjustable and slidable on the side crossbeams 11, a rotating sleeve 14 is rotatably mounted on the adjustable sleeve 13, a coordination shaft 12 and a gripping shaft 19 are fixedly mounted on the rotating sleeve 14, and a clamping roller 20 is rotatably mounted on the gripping shaft 19;

[0038] Two fixing rods 23 are also fixed on the telescopic core shaft of the grabbing telescopic cylinder 9 located in the middle, and a collar 18 is fixed on one end of the fixing rod 23 away from the grabbing telescopic cylinder 9, and a pushing roller 16 is rotatably installed on both sides of the collar 18;

[0039] When the grabbing telescopic cylinder 9 is extended, the top pressure roller 21 moves downward, and at the same time the pushing roller 16 pushes the coordination shaft 12 to rotate relative to the side beam 11, and the clamping roller 20 moves toward the waist of the track 8; until the top pressure roller 21 abuts against the head of the track 8 and the clamping roller 20 abuts against the waist of the track 8.

[0040] In the embodiment of the present invention, the device is set up at the construction site by mechanical equipment (not shown), and then the position of the adjustment base 5 is adjusted by the lateral adjustment component so that the top pressure roller 21 corresponds vertically to the track 8, and then the height adjustment component is started to send the installation platform 7 to the specified height position, and then the grabbing telescopic cylinder 9 is started to extend, the top pressure roller 21 moves downward, and at the same time, the push roller 16 pushes the coordination shaft 12 to rotate relative to the side beam 11, and the clamping roller 20 moves toward the waist of the track 8, until the top pressure roller 21 abuts against the head of the track 8 and the clamping roller 20 abuts against the waist of the track 8, completing the clamping and fixing of the track 8. Subsequently, the height adjustment component is started to shorten and the track 8 is lifted. The track 8 can be pushed along its length direction by the rotation installation of the top pressure roller 21 and the clamping roller 20 to achieve docking adjustment. The adjustment base 5 can also be driven to move by the lateral adjustment component to adjust the distance between the two tracks 8, meeting the flexible adjustment requirements of the track 8 at the construction site. In addition, the supporting moving components facilitate the movement of the entire device, and it can be moved at the construction site without mechanical equipment, which is flexible and convenient; the position of the inverted U-shaped roller frame 22 and the adjustable sleeve 13 can also be adjusted, which makes the grabbing of the rail 8 more reliable and convenient.

[0041] like Figure 1 As shown, as a preferred embodiment of the present invention, the supporting moving assembly includes a supporting wheel 1 and an inverted U-shaped base 2, and an inverted U-shaped base 2 is fixed to the lower ends of the two side branches of the inverted U-shaped arm 3 respectively, the length of the inverted U-shaped base 2 is greater than the width of the inverted U-shaped arm 3, and the connection between the inverted U-shaped arm 3 and the inverted U-shaped base 2 is located in the middle position of the top of the inverted U-shaped base 2, meeting the demand for stable support; a plurality of supporting wheels 1 are evenly distributed on the inner side of the inverted U-shaped base 2, which is conducive to the stable movement of the device.

[0042] Preferably, the supporting wheel 1 has a brake structure and can maintain a stable state after moving, which is not limited.

[0043] The lateral adjustment assembly includes a lateral adjustment telescopic cylinder 4, and a lateral adjustment telescopic cylinder 4 is respectively installed and fixed on the two side branches of the inverted U-shaped arm 3. The telescopic core shaft ends of the two lateral adjustment telescopic cylinders 4 are fixedly connected to the lower sides of the two adjustment pedestals 5. The two lateral adjustment telescopic cylinders 4 can be used to drive the two adjustment pedestals 5 to move their positions respectively.

[0044] The height adjustment component includes a height adjustment telescopic cylinder 6. A plurality of height adjustment telescopic cylinders 6 are arranged on the outer side between the adjustment base 5 and the installation platform 7. The two ends of the height adjustment telescopic cylinder 6 are respectively fixedly connected to the adjustment base 5 and the installation platform 7. The installation platform 7 can be stably driven to rise and fall through the height adjustment telescopic cylinder 6.

[0045] like Figure 1-7As shown, as a preferred embodiment of the present invention, three grabbing telescopic cylinders 9 are provided, and the three grabbing telescopic cylinders 9 are synchronously telescopically controlled; a locking screw 24 for locking and fixing it on the top pressure plate 17 is also installed on the upper side of the inverted U-shaped roller frame 22, thereby ensuring that the inverted U-shaped roller frame 22 remains stable after adjusting its position.

[0046] A fixed rod 23 is fixed on both sides of the telescopic mandrel of the grab telescopic cylinder 9 located in the middle; a roller shaft is rotatably installed on the inner side of the collar 18, and the two push rollers 16 are rotatably connected to the roller shaft, which ensures the stability of the push roller 16 and reduces the friction force of the push roller 16 pushing the coordination shaft 12. In addition, the length of the push roller 16 depends on the adjustment range of the adjustable sleeve 13. On the basis of meeting the strength, the adjustment range of the adjustable sleeve 13 and the length of the push roller 16 can be set as needed without limitation.

[0047] The surface of the side cross beam 11 is provided with a protruding edge 25, and the inner wall of the adjustable sleeve 13 is also provided with a concave groove 26 slidably connected to the protruding edge 25, so as to prevent the adjustable sleeve 13 from rotating, and the reliability is high; the adjustable sleeve 13 is also installed with a locking screw 15 for locking it to the side cross beam 11, so as to ensure the stability of the adjustable sleeve 13 after adjustment.

[0048] Preferably, the number of the clamping rollers 20 installed on the side cross beam 11 is the same as the number of the pressing rollers 21 and corresponds one to one, so that the force on the track 8 is uniform and stable.

[0049] A circumferential groove 27 is provided in the middle of the outer surface of the adjustable sleeve 13, and an elastic coil spring 28 is installed in the circumferential groove 27. One end of the elastic coil spring 28 is fixedly connected to the inner wall of the rotating sleeve 14, and the other end of the elastic coil spring 28 is fixedly connected to the cavity wall of the circumferential groove 27. The elastic coil spring 28 is used to ensure that the coordination shaft 12 is always in close contact with the surface of the push roller 16, that is, no matter whether the push roller 16 rises or falls, the overall structure composed of the coordination shaft 12, the rotating sleeve 14, the clamping shaft 19 and the clamping roller 20 can ensure stability.

[0050] Preferably, when the grabbing telescopic cylinder 9 is shortened to the limit position, the minimum distance between the clamping rollers 20 on both sides is greater than the head width of the track 8, ensuring that the clamping rollers 20 on both sides can be placed in the waist position of the track 8. It can be understood that there is no limitation on the angle between the coordination axis 12 and the grabbing axis 19, as long as it can meet the needs of grabbing the track 8; the model of the track 8 is relatively uniform, and the height adjustment telescopic cylinder 6 can be used to deliver the mounting platform 7 to a fixed position, and the relative positions of the clamping rollers 20 and the top pressure rollers 21 can be initialized and installed, which will not be described in detail.

[0051] The above embodiment of the present invention provides a track adjuster for traffic engineering, and its working principle is as follows:

[0052] 1) The entire device is erected on the construction site by mechanical equipment, and the supporting moving assembly (including the supporting roller 1 and the inverted U-shaped base 2) at the lower end of the inverted U-shaped arm 3 ensures that the device can move smoothly on site and can stay firmly at the required position;

[0053] 2) Use the lateral adjustment assembly (mainly the lateral adjustment telescopic cylinder 4) to adjust the position of the adjustment base 5 so that the top pressure roller 21 corresponds vertically to the rail 8, thereby ensuring that the head of the rail 8 can be accurately contacted by the top pressure roller 21 on the top pressure plate 17; start the height adjustment assembly (mainly composed of the height adjustment telescopic cylinder 6) to lift the installation platform 7 to a specified height position so that the top pressure roller 21 is located at an appropriate height to contact the head of the rail 8;

[0054] 3) When the grabbing telescopic cylinder 9 is extended, the top pressure roller 21 moves downward and contacts the head of the rail 8; at the same time, the push roller 16 pushes the coordination shaft 12 to rotate relative to the side crossbeam 11, causing the clamping roller 20 to approach the waist of the rail 8 and finally contact it, completing the clamping and fixing of the rail 8;

[0055] 4) Once the rail 8 is clamped and fixed, the rail 8 can be shortened and lifted by adjusting the height adjustment assembly; the rotation characteristics of the top pressure roller 21 and the clamping roller 20 can be used to make fine adjustments along the length direction of the rail 8 to achieve the adjustment of the docking of the rail 8. In addition, the lateral adjustment assembly can be used to drive the adjustment base 5 to move and adjust the distance between the two rails 8.

[0056] In summary, the track adjuster for traffic engineering realizes efficient, flexible and precise adjustment of the track 8, thereby improving the work efficiency at the construction site and the installation quality of the track 8.

[0057] There is no specific limitation on the control, model and circuit connection of each component, which can be flexibly set in practical application. The circuits, electronic components and modules involved are all prior art, and those skilled in the art can fully implement them. It is needless to say that the content protected by the present invention does not involve improvements to software and methods.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
