Abstract
Description
Technical Field
[0001] This utility model relates to a railway maintenance machine, specifically a drainage hole clearing device for railway bridges. Background Technology
[0002] The ballast bed is an important component of the railway track and forms the foundation of the track frame. It typically refers to the ballast (stone ballasting) layer laid on the roadbed surface beneath the railway sleepers. Its main functions are to support the sleepers, evenly transfer the enormous pressure from above the sleepers to the roadbed surface, fix the sleepers' position, prevent longitudinal or lateral movement, significantly reduce roadbed deformation, and mitigate the impact of locomotive and rolling stock wheels on the rails. It also includes drainage holes for bridges.
[0003] Bridge drainage holes are key areas for ensuring drainage of existing railway lines. Dust and rainwater accumulate in the bridge track bed over a long period of time, which can lead to dirt and hardening of the railway bridge track bed, poor drainage, and even track bed frost heave and mud leakage. Therefore, it is necessary to dredge the bridge drainage holes every once in a while.
[0004] However, due to the slope of the ballast in the drainage hole area of railway bridges, it is impossible to use a cleaning machine to clean it completely. As a result, the drainage hole area will still be blocked and the drainage will not be smooth. Therefore, the ballast in the drainage hole area of railway currently relies on manual dredging. However, manual dredging is not thorough and uneven, and it is difficult to carry out construction in sections with severe ballast compaction, which also poses safety hazards. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a drainage hole clearing device for railway bridges.
[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0007] A drainage hole clearing device for railway bridges includes: a fixed crossbeam located below the frame of a screen cleaning machine, one end of which is connected to the frame of the screen cleaning machine via an ultra-high adjustment cylinder, and the other end of which is hinged to the fixed seat of the screen cleaning machine frame via a connecting seat.
[0008] The bottom of the fixed crossbeam is provided with a guide rail, and a slider is provided on the guide rail. The bottom of the slider is connected to the lateral movement device, and the lateral movement device is connected to the lateral movement cylinder. The lateral movement cylinder is used to drive the lateral movement device to move laterally as the slider moves on the guide rail.
[0009] The bottom of the lateral movement device is hinged to one end of the rotating arm, and the other end of the rotating arm is hinged to the vibrating pick. A lifting cylinder is provided between the rotating arm and the lateral movement device. The vibrating pick rotates through clamping cylinders connected to the vibrating pick and the rotating arm respectively.
[0010] In one embodiment of this utility model, the vibrating pick includes a pick arm, an excitation motor, and a pick tooth. The upper end of the pick arm is connected to the clamping cylinder, the upper middle part is hinged to the rotating arm, and the lower end is provided with the pick tooth.

[0027] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.
[0028] This utility model embodiment provides a drainage hole clearing device for railway bridges, such as... Figure 1 – Figure 3 As shown, it includes: a fixed crossbeam 3 located below the screen cleaning machine frame 12, one end of the fixed crossbeam 3 being connected to the screen cleaning machine frame 12 via an ultra-high adjustment cylinder 1, and the other end being hinged to the fixed seat of the screen cleaning machine frame 12 via a connecting seat 16;
[0029] like Figures 1-4As shown, the bottom of the fixed crossbeam 3 is provided with a guide rail 14, and a slider 15 is provided on the guide rail 14. The bottom of the slider 15 is connected to the transverse moving device 4, and the transverse moving device 4 is connected to the transverse moving cylinder 17. The transverse moving cylinder 17 is used to drive the transverse moving device 4 to move laterally as the slider 15 moves on the guide rail 14.
[0030] The bottom of the transverse moving device 4 is hinged to one end of the rotating arm 7. A lifting cylinder 5 is provided between the rotating arm 7 and the transverse moving device 4. The lifting cylinder 5 is used to drive the rotating arm 7 to rotate around the hinge axis of the transverse moving device 4 and the rotating arm 7 when it is extended and shortened. In the working state, the lifting cylinder 5 is kept in an unloaded state, so as to ensure that the unblocking device is pressed down by gravity when it vibrates and will not damage the surface of the railway bridge.
[0031] In addition, the other end of the rotating arm 7 is hinged to the vibrating pick 8. The vibrating pick 8 is rotated by a clamping cylinder 6 connected to the vibrating pick 8 and the rotating arm 7 respectively. Specifically, when the clamping cylinder 6 extends or retracts, it drives the vibrating pick 8 to rotate about the hinge axis (e.g., a pin) of the rotating arm 7 and the vibrating pick 8.
[0032] Furthermore, such as Figures 1-6 As shown, the vibratory pick 8 includes a pick arm, an excitation motor 9, and a pick tooth 11. The upper end of the pick arm is connected to the clamping cylinder 6, the middle and upper part is hinged to the rotating arm 7, and the lower end is provided with the pick tooth 11. The excitation motor 9 is located in the middle and lower part of the pick arm.
[0033] In use, the lateral movement cylinder 17 is controlled to move the lateral movement device 4 above the drainage hole of the railway bridge. Then, the lifting cylinder 5 is controlled to lower the rotating arm 7 and the vibratory pick 8 to the ballast in the drainage hole area. After that, the lifting cylinder is adjusted to the floating unloading state, that is, the rotating arm 7 and the vibratory pick 8 press down on the ballast by gravity alone, and the teeth 11 at the lower end of the vibratory pick 8 are inserted into the ballast.
[0034] After that, the power supply of the exciter motor 9 is turned on, and the vibrating pick 8 starts to vibrate and clear the drainage hole. At this time, the clamping cylinder 6 is controlled to extend and retract at a certain frequency, so that the vibrating pick 8 also swings back and forth slightly while vibrating, thereby better clearing the drainage hole of the slab track bed. The excitation force of the exciter motor 9 can be adjusted by the frequency converter.
[0035] During the dredging operation, since the lifting cylinder 5 is set to a floating state, the vibratory pick 8 will naturally float up when encountering hard obstacles such as cover plates or the upper surface of bridges, thus protecting the railway bridge.
[0036] In addition, when the railway bridge is curved and the track has superelevation, the attitude of the entire device can be adjusted by superelevation adjustment cylinder 1 to adapt to the needs of superelevation track.
[0037] The drainage hole clearing device for railway bridges provided by this utility model sets the fixed crossbeam 3 below the screen cleaning machine frame 12 and connects it to the screen cleaning machine frame 12 through the high-elevation adjustment cylinder 1 and the connecting seat 16, thereby ensuring that it does not interfere with the screen cleaning machine frame 12 and other devices when it is in the retracted position, and does not encroach on the railway clearance 18.
[0038] In addition, the device, through the combined action of the ultra-high adjustment cylinder 1, the transverse cylinder 17, the lifting cylinder 5, and the clamping cylinder 6, can ensure that the vibratory pick 8 and the pick teeth 11 can effectively unclog the bridge drainage holes, guarantee the quality of unclogging, and protect the bridge surface from damage.
[0039] The structure of this device will be further explained below.
[0040] Regarding the structure of the transverse movement device 4, in one possible implementation, such as Figure 5 and Figure 6 As shown, the transverse movement device 4 includes a frame base plate 4-1, a frame side plate 4-2 located above one side of the frame base plate 4-1, and two support plates 4-3 located below the frame base plate 4-1.
[0041] The frame base plate 4-1 is fixedly connected to the bottom of the slider 15. The bottom of the two support plates 4-3 is provided with a rotating shaft 10. The two support plates 4-3 are hinged to the rotating arm 7 through the rotating shaft 10. The bottom of the lifting cylinder 5 is connected to the rotating arm 7, and the top is connected to the frame side plate 4-2, thereby ensuring that the lifting cylinder 5 can drive the rotating arm 7 to move when it extends or retracts.
[0042] Furthermore, one end of the transverse cylinder 17 is connected to the fixed crossbeam 3, and the other end is fixedly connected to the frame base plate 4-1, thereby enabling the transverse cylinder 17 to drive the transverse device 4 to move laterally along the guide rail 14 as the slider 15 moves on the guide rail when it extends or retracts; of course, as Figure 5 As shown, a mounting plate 19 is provided on the side of the fixed crossbeam 3 away from the screen cleaning machine frame 12, and one end of the transverse oil cylinder 17 is connected to the mounting plate 19.
[0043] Of course, the unblocking device can also be locked when not in use, such as... Figure 5 and Figure 6 As shown, a locking limiting plate 4-4 is provided on the other side of the frame base plate 4-1, and a baffle 4-5 is provided on the side of the fixed crossbeam 3 away from the frame side plate 4-2. A pin hole is provided on the baffle 4-5, which is used for the positioning pin 4-6 to pass through and abut against the locking limiting plate 4-4 to prevent the transverse movement device 4 from moving laterally.
[0044] In one possible implementation, two pin holes can be provided on the baffle 4-5, through which two positioning pins 4-6 pass and abut against the left and right sides of the locking limit plate 4-4 respectively, preventing the lateral movement device 4 from moving laterally; in another possible implementation, such as Figure 5 As shown, only one pin hole is provided on the baffle 4-5. When the slider 15 moves to the side of the guide rail 14 away from the screen cleaning machine frame 12 ( Figure 5 After being moved to the far right, the positioning pin 4-6 passes through the pin hole and abuts against the side of the locking limit plate 4-4 near the screen cleaning machine frame 12 (i.e., the left side of the locking limit plate 4-4), preventing the transverse movement device 4 from moving laterally.
[0045] In addition, such as Figure 1 and Figure 2 As shown, a locking plate 2 is also provided on the fixed crossbeam 3. The locking plate 2 is located on the same side as the ultra-high adjustment cylinder 1, and it is connected to the screen cleaning machine frame 12 by a pin.
[0046] When not in use, the locking plate 2 and the positioning pins 4-6 can achieve mechanical limiting. Before use, first unlock the locking plate 2 and remove the positioning pins 4-6, and then control the transverse cylinder 17 to move the transverse device 4 above the drainage hole of the railway bridge.
[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
