Description

Technical Field

[0001] The invention belongs to the technical field of track adjustment, and in particular relates to a track adjuster for traffic engineering. Background Art

[0002] In transportation engineering construction, precise track installation and adjustment are crucial for ensuring safe train operation. Traditionally, track installation and adjustment have relied primarily on manual labor and simple mechanical tools, which is not only inefficient but also difficult to ensure high track precision and smoothness. With the development of rail transit, the requirements for track installation quality and accuracy are becoming increasingly stringent, and traditional track adjustment methods are no longer able to meet the demands of modern engineering.

[0003] The shortcomings of existing technologies are: 1) Traditional track adjustment methods mainly rely on manual adjustment, which has poor accuracy and can easily lead to unevenness or misalignment at track joints, affecting the safety and comfort of train operation; 2) Due to the need for a large amount of manual operation, 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) 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 has limitations.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a track adjuster for traffic engineering to overcome the shortcomings in current practical applications. Summary of the Invention

[0010] Two fixing rods are also fixed on the telescopic core shaft of the grabbing telescopic cylinder located in the middle, and a collar is fixed on one end of the fixing rod away from the grabbing telescopic cylinder, and a pushing roller is rotatably installed on both sides of the collar;

[0011] When the grabbing telescopic cylinder is extended, the top pressure roller moves downward, and at the same time the pushing roller pushes the coordination shaft to rotate relative to the side beam, and the clamping roller moves toward the waist of the track; until the top pressure roller abuts the head of the track and the clamping roller abuts the waist of the track.

[0012] A further technical solution is that the supporting moving assembly includes supporting wheels and an inverted U-shaped base, and an inverted U-shaped base is fixed to the lower end of each side branch of the inverted U-shaped arm; a plurality of supporting wheels are evenly distributed and installed on the inner side of the inverted U-shaped base; the length of the inverted U-shaped base is greater than the width of the inverted U-shaped arm, and the connection between the inverted U-shaped arm and the inverted U-shaped base is located in the middle of the top of the inverted U-shaped base.

[0013] A further technical solution is that the lateral adjustment component includes a lateral adjustment telescopic cylinder, and a lateral adjustment telescopic cylinder is respectively installed and fixed on the two side branches of the inverted U-shaped arm, and the telescopic core shaft ends of the two lateral adjustment telescopic cylinders are fixedly connected to the lower sides of the two adjustment platforms; the height adjustment component includes a height adjustment telescopic cylinder, and multiple height adjustment telescopic cylinders are provided on the outer side between the adjustment platform and the installation platform, and the two ends of the height adjustment telescopic cylinder are respectively fixedly connected to the adjustment platform and the installation platform.

[0014] According to a further technical solution, three grabbing and telescopic cylinders are provided, and the three grabbing and telescopic cylinders are controlled to telescope synchronously.

[0015] According to a further technical solution, a second locking screw is installed on the upper side of the inverted U-shaped roller frame for locking and fixing it on the top pressure plate.

The height adjustment assembly then activates to raise the mounting platform to the desired height. The telescopic grabbing cylinder then extends, moving the top pressure roller downward. Simultaneously, the push roller rotates the coordinating shaft relative to the side beam, and the clamping roller moves toward the waist of the rail until the top pressure roller abuts the head of the rail and the clamping roller abuts the waist of the rail, completing the clamping of the rail. The height adjustment assembly then shortens, raising the rail. The rotation of the top pressure roller and clamping roller allows the rail to be pushed along its length to adjust the docking position. The lateral adjustment assembly also drives the adjustment base to adjust the spacing between the two rails, meeting the needs of flexible track adjustments on the construction site. Furthermore, the support and movement assembly facilitates the movement of the entire device, allowing for flexible and convenient movement on the construction site without mechanical equipment. The position of the inverted U-shaped roller frame and adjustable sleeve can also be adjusted, making track gripping more reliable and convenient.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to 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 with reference to specific embodiments.

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

[0035] Adjustment pedestal 5, two adjustment pedestals 5 are slidably installed on the horizontal part of the inverted U-shaped arm 3, and lateral adjustment components for driving the movement of the two adjustment pedestals 5 are respectively installed on both sides of the inverted U-shaped arm 3. 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. 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 of the lower portion of the mounting platform 7. A plurality of inverted U-shaped roller frames 22 are adjustable and slidably mounted on the top pressure plate 17. 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 provided on each side of the lower side of the mounting platform 7, bottom supports 10 are fixed at both ends of the side crossbeams 11, the upper end of the bottom support 10 is connected and fixed to the mounting platform 7, and the side crossbeams 11 can also be adjusted and slidably provided with a plurality of adjustable sleeves 13, a rotary sleeve 14 is rotatably installed on the adjustable sleeve 13, a coordination shaft 12 and a gripping shaft 19 are fixedly installed on the rotary sleeve 14, and a clamping roller 20 is rotatably installed 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. A collar 18 is fixed to one end of the fixing rod 23 away from the grabbing telescopic cylinder 9. 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 an embodiment of the present invention, the device is set up at the construction site using mechanical equipment (not shown), and then the position of the adjustment base 5 is adjusted by the lateral adjustment assembly so that the top pressure roller 21 is vertically aligned with the track 8. The height adjustment assembly is then activated to move the mounting platform 7 to the specified height position. The grabbing telescopic cylinder 9 is then activated to extend, the top pressure roller 21 moves downward, and the push roller 16 simultaneously pushes the coordination shaft 12 to rotate relative to the side crossbeam 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 assembly is activated to shorten the track 8, and the track 8 is raised. The rotation of the top pressure roller 21 and the clamping roller 20 can be used to push the track 8 along its length to achieve docking adjustment. The lateral adjustment assembly can also be used to drive the adjustment base 5 to move to adjust the spacing 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 track 8 more reliable and convenient.

[0041] like Figure 1 As shown, as a preferred embodiment of the present invention, the supporting and 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 end of the two side branches of the inverted U-shaped arm 3. 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 of the top of the inverted U-shaped base 2, meeting the requirements of 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 so as to 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 platforms 5. The two lateral adjustment telescopic cylinders 4 can be used to drive the two adjustment platforms 5 to move their positions respectively.

[0044] The height adjustment component includes a height adjustment telescopic cylinder 6. Multiple height adjustment telescopic cylinders 6 are provided 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 fixedly connected to the adjustment base 5 and the installation platform 7 respectively. The height adjustment telescopic cylinder 6 can stably drive the installation platform 7 to rise and fall.

[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 controlled to extend and retract; the upper side of the inverted U-shaped roller frame 22 is also equipped with a locking screw 24 for locking it to the top pressure plate 17, ensuring that the inverted U-shaped roller frame 22 remains stable after adjusting its position.

[0046] A fixed rod 23 is fixed to each side of the telescopic core of the central grabbing telescopic cylinder 9. A roller shaft is rotatably mounted on the inner side of the collar 18, and both push rollers 16 are rotatably connected to the roller shaft, ensuring the stability of the push rollers 16 and reducing the friction caused by the push rollers 16 pushing the coordination shaft 12. Furthermore, the length of the push rollers 16 depends on the adjustment range of the adjustable sleeve 13. The adjustment range of the adjustable sleeve 13 and the length of the push rollers 16 can be set as needed, provided that the strength is met, and are not limited.

[0047] The surface of the side crossbeam 11 is provided with a protruding ridge 25, and the inner wall of the adjustable sleeve 13 is also provided with a concave groove 26 that is slidably connected to the protruding ridge 25, thereby preventing the adjustable sleeve 13 from rotating and having high reliability; the adjustable sleeve 13 is also equipped with a locking screw 15 for locking it to the side crossbeam 11, thereby ensuring the stability of the adjustable sleeve 13 after adjustment.

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

[0049] A circumferential groove 27 is provided in the middle portion 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 coordinating shaft 12 is always in close contact with the surface of the pushing roller 16, that is, no matter whether the pushing roller 16 rises or falls, the overall structure composed of the coordinating shaft 12, the rotating sleeve 14, the gripping shaft 19 and the clamping roller 20 can ensure stability.

[0050] Preferably, when the grabbing telescopic cylinder 9 is shortened to its limit, 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 inserted into the waist position of the track 8. It is understood that there is no limitation on the angle between the coordination axis 12 and the grabbing axis 19, as long as it satisfies the need for grabbing the track 8. The model of the track 8 is relatively uniform, and the height adjustment telescopic cylinder 6 can be used to move the mounting platform 7 to a fixed position. The relative positions of the clamping rollers 20 and the top pressure rollers 21 are initialized and installed, and no further details are given.

[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 at the construction site using mechanical equipment. The supporting and moving components (including the supporting wheels 1 and the inverted U-shaped base 2) at the lower end of the inverted U-shaped arm 3 ensure 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 is vertically aligned with 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 raise the mounting platform 7 to the specified height position, so that the top pressure roller 21 is at an appropriate height to contact the head of the rail 8;

[0054] 3) When the grabbing telescopic cylinder 9 extends, 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 eventually contact it, completing the clamping and fixing of the rail 8;

[0055] 4) Once the rails 8 are clamped and secured, they can be shortened and raised by adjusting the height adjustment assembly. The rotational characteristics of the top pressure roller 21 and the clamping roller 20 allow for fine adjustments along the length of the rails 8 to achieve alignment. Furthermore, the lateral adjustment assembly can be used to drive the adjustment base 5 to adjust the spacing 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] The control, model, and circuit connection of each component are not specifically limited and can be flexibly configured in actual applications. The circuits, electronic components, and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by this invention does not involve improvements to the software and methods.

[0058] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
