Description

Technical Field

[0001] The invention relates to the technical field of rail grinding, in particular to a double-rail supporting type rail grinding machine. Background Art

[0002] Rail grinders are essential equipment for railway maintenance, primarily used to repair rail surface damage and improve rail surface condition. They can remove surface defects such as wear and cracks, optimize the wheel-rail contact profile, reduce noise and vibration, minimize wheel-rail wear, and extend rail service life. They can also eliminate corrugated rail wear, refine welds, adjust rail surface height, and facilitate line maintenance. They are available in fixed or mobile configurations, flexibly meeting the needs of diverse scenarios, from routine maintenance to emergency repairs.

[0003] Rail grinders include fixed, internal combustion, and electric types. Internal combustion-powered grinders, powered by fuel, offer significant advantages. They are highly maneuverable, requiring no external power source. They can operate flexibly in off-grid areas, such as remote railway lines and those without a power grid, making them particularly suitable for emergency repairs and maintenance of remote lines. They are easy to start and quickly operational, adapting to sudden grinding demands during railway maintenance. Their stable power output meets the power requirements of various grinding conditions, making them exceptionally effective in grinding operations on complex terrain or heavily loaded railways. They are essential equipment for field railway maintenance.

[0004] Rail grinders are divided into two types: single-rail support and double-rail support. The existing double-rail support structure can only grind a single rail in actual use. When another rail needs to be grinded, two workers are needed to lift the structure and change the direction, which is more troublesome in actual work.

[0005] In addition, the staff also reported that during grinding control, because the overlapping shaft is directly overlapped on the surface of the rail, in order to ensure the actual stability of the structural grinding, it is necessary to stand inside the track and push the grinding structure by hand. However, the ground conditions inside the track are complicated, with stones or sleepers, etc. Working in this way often poses serious safety hazards.

[0006] At the same time, the existing structure does not have a structure that can flexibly and reasonably shield and protect the grinding and collect debris, which affects the safety of the workers and seriously affects the working environment.

[0007] On this basis, the present invention provides a double-rail supported rail grinding machine to solve the above problems. Summary of the Invention

When the sliding rod 47 rotates and disengages, the curved slot 67 inside the sliding rod 47 pushes the spherical slider 68 to move in the track of the reset slot 74. At this time, the spherical slider 68 inside each group drives the reset push plate 69 and the reset push frame 73 to move in one direction, and the reset push frame 73 can move the secondary sliding frame 11 and the grinding wheel installed in conjunction with the drive engine 7. The structure is pushed toward the grinding position, and then the sliding rod 47 is directly pushed to drive the sliding main frame 1 to follow the movement, and the sliding main frame 1 and the secondary sliding frame 11 continue to move closer to the grinding direction. After adjusting the position of the sliding main frame 1, the sliding rod 47 is continued to be rotated ninety degrees in the same direction. At this time, the curved slide groove 67 inside the sliding rod 47 will still push the spherical slider 68 to move in the track of the reset slide groove 74. The spherical slider 68 inside each group drives the reset push plate 69 and the reset push frame 73 to push the secondary sliding frame 11 and the grinding structure installed with the drive engine 7 in the grinding direction for the third time, adjust the position of the grinding structure, and keep the sliding rod 47 rotated into the card slot 48, while limiting and fixing the sliding main frame 1.

[0050] S2. While adjusting the position of the sliding main frame 1, the multi-stage telescopic frame 27 near the non-grinding track will be pulled and extended. When the multi-stage telescopic frame 27 is fully extended, the moving sliding main frame 1 continues to drive the multi-stage telescopic frame 27 to move, and the multi-stage telescopic frame 27 drives the limiting frame 40 to move. The limiting frame 40 drives the pushing frame 41 to push one of the adjusting arms 42 to rotate, and cooperates with the meshing wheels 44 that mesh with each other to drive the two adjusting arms 42 and the fastening wheel 45 to rotate inward at the same time, clamping and fixing the middle position of the rail. Finally, the staff stands on the other side and holds the handrail 6 to push and control the structure.

[0051] S3. Before grinding the rail, the first threaded screw 17 can be driven to rotate by rotating the height driving wheel 10 according to the grinding requirements, thereby driving the first threaded sleeve 16 and the lifting plate 18 to rise and fall, and the lifting plate 18 drives the limiting sleeve 21, the supporting slider 20, the supporting sleeve 19, the grinding block mounting port 23 and the grinding block 24 to rise and fall, and the grinding height is adjusted and controlled. At the same time, the limiting block 28 is rotated to disengage the limiting block 28 from the fixed gear 32, and then the angle driving wheel 9 is rotated to drive the connecting shaft 33 and the driving sprocket 31 to rotate. The driving sprocket 31 pushes the chain 29 to move by rotating, and cooperates with the limit between the first connecting rod 36 and the first connecting sleeve 34 to drive the mounting plate 35 and the connecting frame 13 to rotate, and the angle of the connecting frame 13 is adjusted and controlled, thereby adjusting and controlling the grinding angle.

[0052] S4. Finally, during the process of moving the structure, the driving engine 7 can be controlled to work, driving the driving shaft 22, the supporting sleeve 19, the grinding block mounting port 23 and the grinding block 24 to rotate, and the rail surface can be ground with the help of the grinding block 24.

[0053] The present invention has the following technical effects.

[0054] 1. The present invention rotates the sliding rod inside the sliding groove so that the sliding rod is disengaged from the slot inside the sliding groove. The curved groove inside the rotating sliding rod can also push the spherical slider to move in the track of the reset slide groove, thereby driving the spherical slider inside each group to drive the reset push plate and the reset push frame to move in one direction, and the reset push frame can push the secondary sliding frame to the grinding position. The auxiliary pushing process can shorten the subsequent adjustment range and improve the adjustment efficiency when changing the track. After the sliding rod is disengaged, the sliding rod is pushed to drive the sliding main frame to follow the movement. By adjusting and controlling the position of the sliding main frame, different rails can be adjusted and ground without removing the structure, reducing large-scale adjustments to the structure. At the same time, the movement of the sliding main frame can push the multi-stage telescopic frame close to the non-grinded rail to telescopically move after contacting the limit frame. Finally, the multi-stage telescopic frame pulls the limit frame and the push frame to move, and the push frame drives the adjustment arm to rotate, thereby driving the two fastening wheels to move inward, and the non-grinded rail is limited and fastened by the fastening wheels. When the staff pushes on one side, the stability of the structure movement can be improved.

[0055] 2. The present invention drives the second threaded screw to rotate accordingly by rotating the adjusting wheel, thereby driving the secondary sliding frame to move, and at the same time driving the first push block to move accordingly. The position of the secondary sliding frame is adjusted and controlled according to the actual requirements of grinding. When the secondary sliding frame is moved to a suitable position, the inclined surface of the first push block gradually contacts and presses down the first fixed block, driving the first sliding plate and the second push block to follow and descend. The inclined surface of the second push block squeezes and pushes the second sliding plate to move inward, controlling the extension of the second sliding plate. At this time, with the help of the expanded second sliding plate, the debris generated by the grinding work can be shielded and stored.

[0056] Although the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description is not intended to limit the present invention. Various modifications and substitutions of the present invention will be readily apparent to those skilled in the art after reading the above description. Therefore, the scope of protection of the present invention shall be defined by the appended claims.
