Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicles, in particular to a power supply rail system for an APM pivot turnout. Background Art

[0002] APM (Automated People Mover System) is an unmanned, fully automatic passenger rapid transit system with advantages such as moderate capacity, strong gradeability, small turning radius, small civil engineering scale, flexible and convenient vehicle formation, low noise, high ride comfort and low cost. It is widely used in airports, amusement parks, central business districts and urban areas, and has broad application prospects both at home and abroad.

[0003] Since APM vehicles do not provide their own energy, a power supply rail system needs to be laid along the line to ensure that electricity is provided for the continuous operation of the vehicles. Similarly, a power supply rail system should also be laid in the switch area where the vehicles change lines. However, due to the structural characteristics of the switch system, the power supply rail system in this area not only needs to realize its own functional system, but also needs to overcome the shortcomings of small installation space, high installation precision requirements, and the risk of positive and negative short circuit during the switch switching process.

[0034] The specific implementation of the present invention will be further explained in detail below through description of embodiments with reference to the accompanying drawings.

[0035] like Figures 1 to 12As shown, the power supply rail system for the APM pivot turnout includes a power supply rail, an insulating bracket and a grounding rail 3. The power supply rails are arranged in a pair side by side, and the pair of power supply rails are positive and negative power supply rails 1. The power supply rails are arranged on the web 18 of the turnout beam / guide beam through the insulating bracket 2. The grounding rail is arranged between the pair of power supply rails through the power supply rail bracket 16. The turnout beam includes a relatively connected turnout straight beam b and a turnout curved beam a. The pivot end b1 of the turnout straight beam and the pivot end a1 of the turnout curved beam respectively transmit electrical energy to the positive and negative power supply rails on the pivot turnout straight beam and the turnout curved beam through the electrical connection clamp 10 and the power supply jumper cable 12. The vehicle contacts the power supply rail through the collector shoe installed on the bogie to receive power and current; the grounding rail on the turnout beam and the grounding rail on the pivot end guide rail are electrically connected through the grounding rail intermediate joint 13 and the grounding jumper cable 14. The vehicle contacts the grounding rail through the grounding shoe installed on the bogie to achieve equal potential between the vehicle body and the ground, eliminating the hazard of step voltage.

[0036] In the present invention, the positive and negative power supply rails on the guide beam at the movable end c of the turnout, the end of the turnout straight beam, and the end of the turnout curved beam are anchored by the center anchor 4 of the power supply rail, so as to avoid the gap value at the fracture from changing due to thermal expansion and contraction, thereby avoiding the power shoe from falling off; similarly, the grounding rail at this location is anchored by the center anchor 5 of the grounding rail, so as to avoid the grounding shoe from falling off.

[0037] The positive and negative power supply rails on the guide beam at the movable end of the turnout, the end of the straight beam of the turnout, and the end of the curved beam of the turnout are respectively provided with power supply rail insulating rail tips 6, and the corresponding grounding rails are provided with grounding rail insulating rail tips 7; to avoid positive and negative short circuit faults between the positive and negative poles on the straight beam / curved beam and the positive and negative power supply rails on the movable end guide beam during the switch switching process.

[0038] The positive and negative power supply rails on the guide beam at the pivot end of the turnout beam and the end of the turnout beam are anchored by the center anchor of the power supply rail to prevent the gap value at the fracture from changing due to thermal expansion and contraction, thereby preventing the power shoe from falling off; similarly, the grounding rail at this location is anchored by the center anchor of the grounding rail to prevent the grounding shoe from falling off.

[0039] Power supply rail tips 11 are respectively arranged at the ends of the positive and negative power supply rails in the middle of the straight beam and the middle of the curved beam of the turnout. During installation, the air gap value between the two rail tips is set according to the ambient temperature. The air gap value is used to enable the power rails to adapt to the length changes caused by thermal expansion and contraction; the left and right power supply rails of the break are kept electrically connected by electrical connection clamps and jumper cables; a grounding rail expansion joint 9 is arranged at the end of the grounding rail in the middle of the straight beam of the turnout to achieve mechanical and electrical connection of the grounding rail, and at the same time to enable the grounding rail to adapt to the length changes caused by thermal expansion and contraction; the difference from the straight beam of the turnout is that the end of the grounding rail in the middle of the curved beam of the turnout is directly connected through a grounding slide bar 15 to guide the grounding rail to adapt to the length changes caused by thermal expansion and contraction, and the left and right grounding rails of the break are kept electrically connected by the middle joint 13 of the grounding rail and the jumper cable 14.

[0040] Furthermore, the insulating rail tip of the power supply rail, the rail tip of the power supply rail, and the rail tip of the grounding rail are provided with guide angles to guide the collector shoe and the grounding shoe to pass smoothly, thereby avoiding shoe collision and shoe falling failures.

[0041] The grounding rail bracket is equipped with waist-round holes to facilitate installation and adjustment of alignment accuracy during operation and maintenance, avoiding shoe collision and shoe falling failures.

[0042] The short power supply rails 8 provided at the turnout movable end, the straight beam pivot end and the curved beam pivot end are convenient for replacement during operation and maintenance, thereby improving maintenance efficiency and reducing maintenance costs.

[0043] Power supply rail protection covers 17 are installed on the positive and negative power supply rails. In addition to the power supply rail protection covers provided at the connection between the jumper cable and the power supply rail, a feed protection cover is also provided to improve the safety of the power supply rail system maintenance personnel.

[0044] The present invention realizes the power supply demand of APM vehicles operating in the switch area; the positive and negative power supply rails are provided with power supply rail protective covers and feed protective covers, which improves the safety of the power supply rail system maintenance personnel; the power supply rail insulating rail tips are provided at the switch movable end, the straight beam pivot end, and the curved beam pivot end to avoid positive and negative short circuit faults; the central anchor knot is provided at the switch movable end, the straight beam pivot end, and the curved beam pivot end to ensure the power supply rail / ground rail gap and alignment accuracy, and reduce the shoe drop fault; the power supply rail insulating rail tip, the power supply rail rail tip, and the ground rail rail tip are provided with a guide deflection angle to avoid shoe collision and shoe drop faults; the standard short power supply rail is provided at the switch movable end, the straight beam pivot end, and the curved beam pivot end to improve maintenance efficiency and reduce maintenance costs.

[0045] The above is only an illustration of a preferred embodiment of the present invention. The above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0046] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
