Description

Technical Field

[0001] This utility model relates to the field of track maintenance technology, and in particular to a swing-arm type track lifting and shifting device. Background Technology

[0002] Track lifting and aligning devices are typically used in track maintenance to adjust the geometry of the rails, including elevation, curve curvature, and straightness, to eliminate directional and horizontal deviations, ensuring smooth curves and straight lines for safe train operation. This is achieved through two steps: lifting and aligning. Lifting involves adjusting the ballast and sleepers beneath the track to change its height; aligning involves adjusting the track's position to change its direction. These two steps work together to bring the track to the designed geometric configuration, thus meeting the needs of train operation.

The lifting device includes lifting cylinders and lifting hooks. Two lifting cylinders are hinged side by side to the lifting and shifting frame and to the lifting cylinder seats on the tamping car frame. There are two lifting hooks. The top of the lifting hook is connected to the lifting hook lifting cylinder and driven by the lifting hook lifting cylinder to move up and down. The inner side of the lifting hook is connected to the lifting hook lateral movement cylinder and driven by the lifting hook lateral movement cylinder to move laterally. The hook faces of the two lifting hooks are installed side by side at the bottom of the lifting and shifting frame. There are two sets of rail clamping devices, which are installed side by side at the bottom of the lifting and shifting frame. The shifting device includes two sets of shifting wheel sets and two shifting cylinders. The two sets of shifting wheel sets are installed side by side at the bottom of the lifting and shifting frame, thus making it suitable for meter-gauge railways.

[0004] However, the height of the guide wheel and the height of the rail clamp in the rail clamping device in this patent cannot be adjusted, so it cannot be adapted to rails of different specifications. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0029] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

[0032] like Figures 1 to 8 As shown, a swing-arm type track lifting and aligning device includes a track aligning wheel assembly 1 and a rail clamping clamp assembly 3 installed at the bottom of the track lifting and aligning frame 2. The track aligning wheel assembly 1 includes a track aligning wheel 101 and a track aligning wheel bracket 102. The track aligning wheel 101 is installed on the track aligning wheel bracket 102 through a first height adjustment component 103. The rail clamping clamp assembly 3 includes a rail clamping clamp 301 and a rail clamping clamp bracket 302. The rail clamping clamp 301 is installed on the rail clamping clamp bracket 302 through a second height adjustment component 303. Thus, the height of both the track aligning wheel 101 and the rail clamping clamp 301 can be adjusted by the height adjustment component to accommodate rails of different specifications.

[0033] In one embodiment, the first height adjustment component 103 includes an arc plate 1031 and a connecting plate 1032. The arc plate 1031 has five screw holes. One end of the connecting plate 1032 is installed in the arc plate 1031 by screws to different screw holes to adjust the height. The other end of the connecting plate 1032 is connected to the guide wheel 101. There are four guide wheels 101, which are installed on the guide wheel bracket 102 by bolts, washers, etc.

[0034] In one embodiment, the bottom of the track lifting frame 2 is equipped with 4 sets of rail clamping assemblies 3. Each set of rail clamping assemblies 3 includes 2 rail clamps 301. The two rail clamps 301 in each set are driven by rail clamping cylinders 304 to move towards each other to clamp the rail.

[0035] In one embodiment, one end of the rail clamp bracket 302 is a sleeve structure, which is fitted onto the rail clamp 301 and fixed to the rail clamp 301 by the second height adjustment component 303 and bolts. The other end of the rail clamp bracket 302 is a connecting arm structure. The connecting arm is rotatably mounted on the support 204 on the opposite side via a rotating shaft. The two sets of rail clamp cylinders 304 on the front side are mounted on the connecting arm via mounting arms, and the two sets of rail clamp cylinders 304 on the rear side are mounted on the sleeve via mounting arms (this is to avoid interference with the track shifting cylinder 5).

[0036] In one embodiment, the second height adjustment component 303 is an L-shaped plate. The rail clamp 301 and the rail clamp bracket 302 are both provided with grooves. The long side of the L-shaped plate is detachably installed in the groove of the rail clamp bracket 302 by bolts. The short side of the L-shaped plate abuts against the groove on the rail clamp 301. The sleeve structure of the rail clamp 301 and the rail clamp bracket 302 are both provided with multiple screw holes. When adjusting the height, the rail clamp 301 is adjusted up and down in the sleeve of the rail clamp bracket 302 as needed, and then the two are fixed together by the L-shaped plate and bolts.

[0037] In one embodiment, the lifting frame 2 is a T-shaped structure, including a horizontal arm 201 and a vertical arm 202 connected by a pin. The end of the vertical arm 202 away from the horizontal arm 201 is equipped with a hanger 203 by a pin and a spherical bearing.

[0038] In one embodiment, two sets of symmetrically arranged track-lifting cylinders 4 are hinged at the cross arm 201 via a hinge seat. The two track-lifting cylinders 4 are located between two sets of rail clamping assemblies 3 on the same side. Two sets of symmetrically arranged track-shifting cylinders 5 are hinged at the longitudinal arm 202 via a hinge seat. The top ends of both the track-lifting cylinder 4 and the track-shifting cylinder 5 are hinged to cylinder seats 10 via pins.

[0039] In one embodiment, a buffer 6 is installed on the longitudinal arm 202 near the transverse arm 201.

[0040] In one embodiment, such as Figure 5 and 8 As shown, it also includes a locking hook 7. Specifically, the locking hook 7 includes a hook body 701, a mounting plate 702, and a drive cylinder 703. The locking hook 7 is mounted on the frame 8 via the mounting plate 702. The piston rod end of the drive cylinder 703 is connected to the hook body 701. The drive cylinder 703 has a hook lifting part 9 on the longitudinal arm 202 of the track shifting frame 2 for the locking hook 7 to hook and lock. The hook lifting part 9 includes two vertical plates welded to the longitudinal arm 202, and a horizontal shaft is installed between the two vertical plates. When the track shifting operation is not performed, the piston rod extends to drive the hook body 701 to hook onto the hook lifting part 9 for locking. When the track shifting operation is performed, the piston rod retracts, causing the hook body 701 to disengage from the hook lifting part 9.

[0041] Working principle:

[0042] The flange of the track-shifting wheel 101 is tightly fastened to the inner edge of the rail. The rail clamping cylinder 304 pushes the rail clamp 301 to fit tightly against the inner and outer edges of the rail, thus making the device and the rail panel an integral unit. Under the action of the track-lifting cylinder 4, the horizontal arm 201 and the vertical arm 202 of the track-lifting frame 2 swing upward around the joint bearing at the rear end of the vertical arm 202, thus realizing the track-lifting operation. Under the action of the track-shifting cylinder 5, the horizontal arm 201 of the track-lifting frame 2 is pushed to swing left and right around the joint bearing at the rear end of the vertical arm 202. The horizontal arm 201 of the track-lifting frame 2 will also passively swing at a small angle around the front pin, so that the center of the front and rear rail clamps 301 is kept parallel to the track, thus realizing the track-shifting operation.

[0043] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
