Description

Technical Field

[0001] The present invention relates to the technical field of railway sand removal equipment, and more specifically, to a blowing and sucking working device for an orbital sand removal vehicle. Background Art

[0002] Accumulation of sand on railway lines poses great hazards to both operation and maintenance. The hazards of wind and sand to railway operation and maintenance are mainly manifested in: affecting the safety of train operation on the line; causing line hazards; increasing the workload of line maintenance and repair; shortening the service life of steel rails and fasteners; blocking bridges and affecting flood discharge. In sandy areas, wind and sand will cause many hazards to railway operation and maintenance. The most direct and main ones are the phenomena of train deceleration, suspension or derailment caused by subgrade erosion or line sand accumulation. It brings many difficulties to people's daily life and transportation. Timely removal of railway accumulated sand and emergency dredging of railway main lines are important contents of railway maintenance operations. However, so far, mainly sand prevention and manual cleaning of buried sand on railways are adopted, which are carried out in a harsh environment, with a large workload and low efficiency. Patent No. CN105803991A discloses a device for absorbing accumulated sand on tracks, whose sand blowing method is relatively single and difficult to meet the cleaning requirements of staff for accumulated sand. In addition, its sand suction hood cannot be well utilized and it is difficult to clean accumulated sand. Therefore, it is necessary to design and develop a blowing and sucking working device for an orbital sand removal vehicle with high efficiency and remarkable effect to clean accumulated sand, ensuring the safety of train operation, reducing the labor intensity of people, and solving the problems of large labor volume and low efficiency in manual sand removal.

[0046] On the basis of Embodiment 1: As Figure 1As shown, the working vehicle 1 has a frame structure. At each of the four corners of the front and rear sides of the frame, a wheel seat plate 2 is provided. The front end of the wheel seat plate 2 is a locking longitudinal beam, and the rear end is connected to the frame. The wheel seat plate 2 is connected to a wheel axle 3, and the wheel axle 3 supports a working wheel 4 for rolling on the rail during operation.

[0049] As shown in Figure 4 Figure [not provided], the sand blowing device 13 is a box body formed by welding several bent plates. Two side blowing boxes 16 are symmetrically arranged on both sides, and a middle blowing box 36 is in the middle, which is used to blow the accumulated sand on the surface of the ballast bed. Two fastener blowing boxes 35 are arranged on both sides at the position of the rail of the side blowing box 16 to blow the accumulated sand at the fasteners. The inside of the sand blowing device 13 is all interconnected. At the lower part, there is a slender air outlet, the width of the air outlet is 5 - 15 mm, and the angle between the air outlet and the vertical direction is 5 - 15°. Four connecting pipes 17 are arranged at the upper part, and the connecting pipes 17 are connected with polyurethane bellows to introduce the high-speed air flow generated by the blower into the box body of the sand blowing device 13 and eject it from the air outlet. Two connecting plates 18 are arranged at the upper part of the sand blowing device 13, and are connected to the lifting mechanism 11 by bolts through the connecting plates 18.

[0050] As shown in Figure 5 Figure [not provided], the guide posts 19 in the lifting mechanism 11 are fixed on the work vehicle 1. Both ends of the lifting connecting rod 20 pass through a guide post 19 respectively and rise or fall along the guide post 19. The centers of the two support connecting rods 21 in the lifting mechanism 11 are cross-connected together by a pin shaft 22. A lifting roller 23 is arranged at each end of the support connecting rod 21. The upper lifting roller 23 moves in the connecting rod guide groove 24 on the lifting connecting rod 20, and the fixed guide groove 25 is welded on the work vehicle 1. The lower lifting roller 23 moves in the fixed guide groove 25. A jacking guide plate 26 is connected to the pin shaft 22 of the support connecting rod 21, and the sliding seat 27 is fixed on the work vehicle 1. The jacking guide plate 26 moves in the groove of the sliding seat 27. The lower ends of the support connecting rods 21 are respectively connected to the second lifting oil cylinder hinge seats 28, and the second lifting oil cylinder 29 is connected between the two second lifting oil cylinder hinge seats 28. By controlling the extension and retraction of the second lifting oil cylinder 29, the lowering and rising of the lifting connecting rod 20 are driven.

[0051] As shown in Figure 6 Figure [not provided], the lifting connecting rod 20 has a panel 30 with both ends respectively connected to a sleeve 31. The guide post 19 passes through the sleeve 31. Two connecting rod connecting plates 32 are welded on one side of the panel 30, and the connecting rod connecting plates 32 are connected to the connecting plates 18 on the sand blowing device 13 to support the entire blowing and suction device 11. A guide groove formed by welding a bottom plate 33 and four guide plates 34, and the bottom plate 33 is welded on the side of the panel 30. Embodiment 3:

[0052] Based on Embodiment 2, the working mode of the blowing and suction working device of the track sand remover is as follows: when the blowing and suction device 11 performs sand removal operations, the first lifting oil cylinder 5 is adjusted to lower the blowing and suction device 11 onto the rail. If the blowing and suction device 11 is lowered on a curve, the transverse movement oil cylinder 8 needs to be adjusted to make the blowing and suction device 11 swing laterally during the lowering process, so that the working vehicle 1 accurately lands on the rail. The track sand remover travels and the blowing and suction device 11 is pulled along the rail by the traction device 9. The high-speed air flow generated by the blower is ejected from the air outlet in the sand blowing device 13, blowing the accumulated sand and garbage pollutants on the railway bed into the suction port of the sand suction device 12. At the same time, the negative pressure generated by the suction fan forms a suction force (suction air flow) at the suction port to suck the corresponding accumulated sand or garbage pollutants into the sand suction device. Then, it passes through the connecting pipe, is filtered by the dust removal system, and falls into the conveyor belt through the discharger. The material is transported away by the conveyor belt.

[0053] The above is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
