Description

Technical Field

[0001] The present invention belongs to the technical field of track maintenance devices, and in particular relates to a maintenance device for high-speed railway tracks. Background Art

[0002] High-speed railway tracks consist of two parallel steel rails fixed to sleepers, supporting the movement of trains along the track's direction of installation. Tracks are typically I-shaped, with the upper end of the rail head in contact with the train's wheels during operation. Due to this contact, the upper end of the rail head remains polished. However, the rail waist and upper end of the rail foot support the rail head and do not come into contact with the wheels. Due to prolonged exposure to air, rust can develop during use, requiring regular cleaning and maintenance of these rusted areas.

[0003] The rust on the rail waist and rail bottom of existing railway tracks is usually cleaned and maintained by rolling with a wheel brush. During the cleaning process, due to the different angles of the corners between the rail head, rail waist and rail bottom, there is a blind spot at the corner during the wheel brush cleaning process, so that the rust at the corner cannot be cleaned in time, thereby affecting the safety and life of the railway track.

[0004] Based on this, a maintenance device for high-speed railway tracks is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1-4 As shown, the present invention provides a technical solution: a maintenance device for high-speed railway tracks, including a rail vehicle main frame 1, two brackets 2 are symmetrically installed on both sides of the rail vehicle main frame 1, and reinforcing ribs 21 are installed between the brackets 2 and the rail vehicle main frame 1. The reinforcing ribs 21 can improve the stability of the connection between the brackets 2 and the rail vehicle main frame 1, thereby improving the stability of the entire device during use.

[0032] A rail wheel mechanism 3 is movably connected inside the bracket 2. The spacing between the two rail wheel mechanisms 3 perpendicular to the rails 8 is the same as the rail gauge. The rail wheel mechanism 3 is used to complete the movement of the rail vehicle main frame 1 on the rails 8, that is, the rail wheel mechanism 3 can drive the rail vehicle main frame 1 to complete the movement of its position on the rails 8, thereby facilitating the cleaning and maintenance of rust at different positions on the rails.

[0033] The rail wheel mechanism 3 includes a driving wheel 31, a connecting frame 32 and a lifting hydraulic cylinder 33. The driving wheel 31 is driven by a driving motor, and the driving wheel 31 contacts the middle of the top surface of the rail head of the rail 8, that is, the forward or backward driving movement operation of the driving wheel is completed by the contact of the driving wheel 31 on the rail head of the rail 8.

[0034] The driving wheel 31 is rotatably connected in the connecting frame 32. A lifting hydraulic cylinder 33 is installed at the top of the connecting frame 32. The top of the lifting hydraulic cylinder 33 is installed in the bracket 2. The height of the track wheel mechanism 3 can be adjusted by the lifting hydraulic cylinder 33, so that the working height of the rust cleaning and maintenance mechanism 7 can be adjusted by adjusting the height of the track wheel mechanism 3, thereby meeting the rust cleaning and maintenance operations on the side of the rail under different working conditions.

[0035] The bottom end of the bracket 2 is fixed with a connecting seat 4 on both sides of the rail 8, and the bottom end of the connecting seat 4 is fixed with an anti-slip plate 5. The side end of the anti-slip plate 5 is movably connected to the rust cleaning and maintenance mechanism 7 through the adjustment frame 6.

[0036] The two anti-slip plates 5 are symmetrically arranged, and the distance between the inner sides of the two anti-slip plates 5 is 10-15 mm larger than the width of the rail head. The anti-slip plates 5 can prevent the rail wheel mechanism 3 from slipping off the rail 8 during use, thereby improving the stability of the entire maintenance device during use.

[0037] The adjusting frame 6 includes a transverse rod 61, a broken line rod 62 and an adjusting hydraulic cylinder 63. One end of the transverse rod 61 is fixed to the outside of the anti-slip plate 5, and the other end of the transverse rod 61 is rotatably connected to the broken line rod 62. The transverse rod 61 and the broken line rod 62 are movably connected with the adjusting hydraulic cylinder 63. The adjustment of the inclination angle between the transverse rod 61 and the broken line rod 62 is completed by adjusting the hydraulic cylinder 63. That is, when rust cleaning is not performed, that is, when the rust cleaning and maintenance mechanism 7 is not in use, the adjustment is as follows: Figure 3 As shown, the hydraulic cylinder 63 is adjusted to extend to increase the inclination angle of the transverse rod 61 and the broken line rod 62, so that the broken line rod 62 can drive the rust cleaning and maintenance mechanism 7 away from the rail waist side of the rail 8, that is, the rust cleaning and maintenance mechanism 7 does not contact the rail 8, which is beneficial to the movement and adjustment of the entire device.

[0038] The bottom transverse section of the broken line rod 62 is vertically fixed to the middle of the outer side of the support plate 71. The rust cleaning and maintenance mechanism 7 includes a support plate 71, a driving wheel 72, a driven wheel 73, an auxiliary frame 74, a tension wheel 75 and a cleaning belt ring 77. The support plate 71 is a rectangular plate, and the top of the support plate 71 is rotatably connected to the driving wheels 72 near both sides. The bottom end of the support plate 71 is rotatably connected to the position corresponding to the two driving wheels 72. The inner side of the support plate 71 is further provided with an auxiliary frame 74 and a tension wheel 75 between the driving wheel 72 and the driven wheel 73 at the same vertical end.

[0039] The auxiliary frame 74 includes a lateral frame 741, a limiting plate 742 and an intermediate frame plate 743. There are two lateral frames 741, and the lateral frames 741 are arc-shaped structures. An arc-shaped limiting plate 742 is fixed on the inner side of the lateral frame 741. The limiting plate 742 is movably connected to the inner side of the limiting groove 772. The two lateral frames 742 are fixed on the inner side of the intermediate frame plate 743. An inclined connecting rod 78 is fixed on the outer side of the intermediate frame plate 743. The inclination angle of the inclined connecting rod 78 is adjusted according to the inclined surface of the bottom of the rail 8 to be cleaned. By adjusting the inclination of the inclined connecting rod 78, the cleaning belt ring 77 can be in contact with the connection between the rail waist and the rail bottom of the rail 8, thereby improving the cleaning efficiency and cleaning quality of rust.

[0040] The other end of the inclined connecting rod 78 is fixed on the support plate 71 at an angle, and the cleaning belt ring 77 can be close to the connection between the waist and the bottom of the rail 8 through the auxiliary frame 74, thereby reducing the occurrence of cleaning blind spots on the bottom side of the rail 8 during the rust cleaning process.

[0041] The lateral frame 741 and the limiting plate 742 have the same curvature, and the curvature of the lateral frame 741 is the same as the curvature between the rail waist and the rail bottom of the rail 8, thereby facilitating the stable operation of the cleaning belt ring 77 during the rotation cleaning process.

[0042] The clamping wheel 75 is movably connected to the side of the support plate 71 through the clamping cylinder 76. The clamping cylinder 76 is installed at an angle on the side of the support plate 71. By adjusting the length of the clamping cylinder 76, the clamping wheel 75 is directed toward the connection between the rail head and the rail waist of the rail 8, so that the cleaning belt ring 77 can be tightly attached to the connection between the rail head and the rail waist of the rail 8 under the action of the clamping wheel 75, which can further reduce the occurrence of cleaning blind spots and improve the quality of rust cleaning on the side of the rail 8.

[0043] The driving wheel 72 is driven to rotate by an independent driving motor, that is, the cleaning belt ring 77 can be driven by the driving wheel 72 to rotate clockwise or counterclockwise on the outside of the driving wheel 72, the driven wheel 73, the auxiliary frame 74 and the pressing wheel 75.

[0044] In order to prevent the cleaning belt ring 77 from slipping during the rotation process, anti-slip protrusions are provided on both outer sides of the driving wheel 72, the driven wheel 73 and the pressing wheel 75.

[0045] Two cleaning belts 77 are provided on the support plate 71, and the cleaning belts 77 are wound around the outer sides of the driving wheel 72, the driven wheel 73, the auxiliary frame 74 and the pressing wheel 75 on the same side of the support plate 71;

[0046] Specifically, the cleaning belt ring 77 includes an inner ring 771, a limiting groove 772 and a rust cleaning brush layer 773. The inner ring is made of rubber, and the brush unit is made of a wire brush. By fixing the brush unit to the structure outside the inner ring made of rubber, the inner ring 771 can drive the multiple wire brushes on the outside to move during rotation, thereby completing the cleaning of the rust on the side of the rail 8.

[0047] The inner side of the inner ring 771 is provided with anti-slip grooves, and limiting grooves 772 are symmetrically provided on the side of the inner ring 771. The limiting grooves 772 are movably connected to the auxiliary frame 74. The rust cleaning bristle layer 773 is composed of multiple bristle units, and the multiple bristle units are fixed at equal intervals on the outside of the inner cavity 771 to form the rust cleaning bristle layer 773. The rust cleaning bristle layer 773 faces the side of the rail 8, and the cleaning and maintenance of the rust on the side of the rail is completed through two rust cleaning and maintenance mechanisms 7.

[0048] Specifically, when cleaning and maintaining the rust on the waist and bottom sides of the rail 8, the rail wheel mechanism 3 is first used to move the entire device to the area of ​​the rail 8 to be cleaned, and then the hydraulic cylinder 63 is used to adjust the inclination angle between the transverse rod 61 and the broken line rod 62, and adjusted until the auxiliary frame 74 drives the cleaning belt ring 77 to stop at the waist and bottom sides of the rail 8, and then the tightening cylinder 76 is used to drive the tightening wheel 75 to extend, and the tightening wheel 75 is extended to the connection between the cleaning belt ring 77 on the outside of the tightening wheel 75 and the waist and rail head of the rail 8, thereby completing the adjustment of the rust cleaning and maintenance mechanism 7 before rust cleaning and maintenance;

[0049] Then, the driving motor of the driving wheel 72 is started to drive the driving wheel 72 to rotate. During the rotation of the driving wheel 72, the cleaning belt ring 77 can be driven to rotate outside the driving wheel 72, the driven wheel 73, the auxiliary frame 74 and the pressing wheel 75. During the rotation of the cleaning belt ring 77, the outer rust cleaning brush bristle layer 773 can be driven to move longitudinally and rub against the outer side of the rail 8, thereby completing the cleaning and maintenance of the rust on the outer side of the rail under the action of the wire brush;

[0050] During the cleaning and maintenance operation of the rust cleaning and maintenance mechanism 7, the track wheel mechanism 3 can be synchronously started to drive the entire device to move back and forth on the outside of the rail 8, which can drive the rust cleaning and maintenance mechanism 7 to move laterally on the outside of the rail 8, thereby completing the synchronous cleaning and maintenance operation of the rust on the outside of the rail 8 in the horizontal and vertical directions, which can not only reduce the blind spots of rust cleaning, but also improve the cleaning and maintenance efficiency. It is convenient and practical, and is conducive to use in the maintenance of high-speed railway tracks.
