Description

Technical Field

[0001] The invention belongs to the technical field of rail transportation, and in particular relates to a friction wheel locomotive marshaling system running on three tracks with a large slope and a parking method thereof. Background Art

[0002] In recent years, with the development of shield tunneling technology, the excavation diameter of tunnels has gradually extended from the 6m level of conventional subway tunnels to larger and smaller directions. The number of shield tunnels with small diameters and large slopes is increasing. The slopes of tunnels such as coal mines, water storage and energy storage, oil and gas pipelines, and integrated pipe galleries have reached more than 70‰. The exchange and transportation of materials inside and outside the tunnel has become a major problem during tunnel excavation construction.

[0003] For tunnels with a slope of more than 50‰, it is difficult for conventional tunnel traction locomotives to operate safely. One solution is to use a dual-power traction locomotive with a drive unit, in conjunction with a three-track track to complete the material transportation task inside and outside the tunnel. The so-called three-track track means that there is a friction wheel track for friction wheels between two conventional steel rails. The friction wheel track can generate power for the friction wheel and generate friction braking when clamped. However, for large slopes and long locomotive formations, the friction braking between the friction wheel and the friction wheel track is still insufficient, and more forms of parking anti-skid mechanisms are needed.

The winch mechanism is fixed to the rear end surface of the car body, and the upper end of the oblique cable is wound around the winch mechanism. The lower end of the oblique cable is connected to the anti-slip end of the flip frame. The flip frame is provided with a limiting groove on the surface facing the car body. After the flip frame is released and dropped by the oblique cable driving mechanism, it is hooked with the supporting structure of the three rails to prevent the car body from slipping on the three rails with a large slope.

[0006] The flip frame includes two longitudinal bars and a plurality of transverse bars, each of which is arranged between two longitudinal bars to form the flip frame as a whole, and the transverse bar located at the hinged end of the flip frame is assembled in the rotating hole of the hinged seat to serve as a rotating axis; the limiting groove is opened at the anti-slip end of the longitudinal bar and faces the rear end surface of the vehicle body, and the longitudinal bar is a telescopic rod body.

[0013] Example: Figure 1-5As shown, the present embodiment specifically relates to a friction wheel locomotive system running on a steep three-track and a parking method thereof, wherein the steep three-track here refers to a track structure with a slope of more than 50‰, and the three-track includes side rails 31 located on both sides and a friction wheel rail 32 arranged in the middle, and the friction wheel locomotive system includes a plurality of car bodies 1 connected in sequence, namely a man car 1a, a locomotive 1b, a dry powder tank transport car 1c, a bean-grain stone transport car 1d, a segment transport car 1e, and a flatbed transport car 1f, wherein the man car 1a is used to carry staff, the locomotive 1b is used to drive the entire locomotive system, and the dry powder tank transport car 1c, the bean-grain stone transport car 1d, the segment transport car 1e and the flatbed transport car 1f are all used to load corresponding construction materials and equipment.

[0014] like Figure 2 As shown, the three rails 3 also include transverse channel steel sleepers 36, which are arranged at intervals in the longitudinal direction, wherein the side rails 31 are fixed to the transverse channel steel sleepers 36 by fasteners 34 and limit members 35, and the friction wheel rail 32 is centrally arranged and fixed to the transverse channel steel sleepers 36 by trapezoidal support members 33.

[0015] like Figure 1-5 As shown, an anti-slip mechanism 2 is respectively provided at the rear end of each car body 1, and the anti-slip mechanism 2 includes an articulated seat 23, a turning frame 24 and an inclined cable driving mechanism. The articulated seat 23 is fixed to the lower rear end of the car body 1, and the two ends of the turning frame 24 are respectively an articulated end and an anti-slip end. The articulated end of the turning frame 24 is articulated on the articulated seat 23, and the anti-slip end of the turning frame 24 is connected to the inclined cable driving mechanism; specifically, the inclined cable driving mechanism includes a winch mechanism 21 and an inclined cable 22, the winch mechanism 21 is fixed to the rear end of the car body 1 and is located at the middle height position of the car body 1, one end of the inclined cable 22 is wound around the winch mechanism 21, and the other end is connected to the anti-slip end of the turning frame 24, and the winch mechanism 21 can control the rotation angle of the turning frame 24 by forward and reverse rotation.

[0016] like Figure 4 and 5As shown, the turning frame 24 includes two longitudinal bars 241, a transverse bar 242 and a plurality of transverse bars 243. The transverse bar 242 is arranged at the hinged ends of the two longitudinal bars 241 and is assembled in the hinge seat 23 to form a rotating hinged fit. Two transverse bars 243 are connected between the two longitudinal bars 241 to strengthen the overall structural strength of the turning frame 24. A limiting groove 25 is provided at the anti-slip end of the longitudinal bar 241 facing the rear end surface of the vehicle body 1. The limiting groove 25 is a quadrilateral opening groove. One side of the quadrilateral opening groove can be flush with the top side of the trapezoidal support member 33 of the friction wheel rail 32. The specific contact part is the top side of the trapezoidal support member 33 and the part located on both sides of the friction wheel rail 32. It should be noted that the longitudinal rod 241 in this embodiment is specifically a telescopic rod body, which controls the extension or contraction of the anti-slip end of the longitudinal rod 241 to control whether the limit groove 25 is in contact with the trapezoidal support member 33, and realizes the hook limit in the longitudinal direction to prevent the car body 1 from slipping on the three-track 3 with a large slope.

[0017] like Figure 1-5 As shown, the parking method of the friction wheel locomotive marshaling system running on the steep three-track in this embodiment includes the following steps: (1) When the friction wheel locomotive marshaling system is ready to stop running on the three tracks 3 with a large slope, the friction wheel pair 12 is controlled to clamp the friction wheel rail 32 in the three tracks 3 to reduce the vehicle speed until it stops. At this time, the winch mechanism 21 is controlled to release the inclined cable 22 to gradually rotate the turning frame 24 from a vertical state to a tilted downward state until the turning frame 24 is placed on the trapezoidal support member 33. Then, the longitudinal rod 241 of the turning frame 24 is controlled to contract so that the limiting groove 25 on the longitudinal rod 241 contacts the top edge of the trapezoidal support member 33 of the friction wheel rail 32, so that the two are hooked, forming a longitudinal limit and anti-slipping effect on the car body 1; of course, if the limiting groove 25 is not completely in contact with the trapezoidal support member 33 at this time, the friction wheel pair 12 can be appropriately loosened to allow the car body 1 to move forward slightly longitudinally so that the limiting groove 25 is completely hooked and contacted with the trapezoidal support member 33.

[0018] (2) When the friction wheel locomotive marshaling system is ready to continue moving, the longitudinal rod 241 is controlled to extend so that the limit groove 25 is out of contact with the trapezoidal support member 33, and then the inclined cable 22 driving mechanism is controlled to rotate and lift the tensioning turning frame 24 until it is close to the rear end surface of the car body 1.

[0019] The invention has the advantages that an anti-slip mechanism is arranged on each car body of the locomotive formation, so that effective parking can be achieved on three tracks with a large slope, and the slip is prevented, thereby effectively alleviating the parking pressure of the friction wheel pair and reducing its wear.
