Technical Field

The invention belongs to the field of rail transit, and particularly relates to a current connection device at a turnout and a use method thereof.

Background

The urban rail transit power supply system is increasingly diversified, and a power supply mode of adopting the lap joint of the rail and the boot to supply current or return current is increasingly used in engineering practice. Because the lines in the field section have complicated trend, the number of turnouts is large. Under the requirement of vehicle passing clearance, a contact rail (return rail) at the position of a turnout must be provided with a fracture, so that a dead zone appears in a part of an operating line in a field section. Once the vehicle stops in the non-electricity area, the vehicle cannot drive away by itself.

At present, two schemes for solving the problems are provided, namely a vehicle-mounted battery pack is arranged to drive the locomotive to run out of a dead zone or an engineering vehicle is adopted to pull the locomotive to separate from the dead zone. If the existing method for driving the vehicle-mounted battery pack to leave the dead zone is to automatically detect the network voltage for starting, voltage impact exists on other electrical equipment, which is not beneficial to normal use of the equipment; if the manual starting is performed, the operation of a driver is increased. By adopting the method of the engineering vehicle traction, the vehicle passing time is greatly prolonged, the workload of maintenance personnel is increased, and the normal passing of other vehicles in a field section can be hindered. The two schemes are that the vehicle can be started after the vehicle loses power and falls into a bow, the former increases vehicle-mounted electrical equipment, and the latter increases vehicle passing time.

Detailed Description

In order to make the technical solutions of the present invention better understood, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Example one

The embodiment of the invention provides a current junction device at a turnout, which comprises a current junction rail 1, a rail driving device 2 and an insulating support 3, wherein the current junction rail 1 is positioned between two sections of common rails 5 and is electrically communicated with the common rails 5. The common rail 5 is a contact rail or a return rail. The current splicing rail 1 is connected with a rail driving device 2 through an insulating support 3, and the rail driving device 2 is used for driving the current splicing rail 1 and the insulating support 3 to move in a lifting and/or translation mode. The end of the common rail 5 is provided with an end bend 4, the structure of which is shown in fig. 5. The end part of the current connecting rail 1 is also provided with an end elbow 4, and the structure is shown in figure 6. The end elbow 4 comprises a straight section and a downward bending section, the straight section of the end elbow 4 of the current connecting rail 1 is embedded with the straight section of the end elbow of the common rail 5, and the width of the downward bending section is slightly smaller than half of the width of the straight section. And a buckle type continuous connection disconnecting link 6 for electrical communication is arranged on the end elbow 4. The end elbow 4 of the buckle type splicing knife switch 6 is arranged, the cutting positions of the upper flange and the lower flange are not aligned, and the cutting positions of the upper flange and the lower flange are determined according to the moving path of the current splicing rail 1 during action, the contact form of the rail and the shoe and the size of the splicing knife switch 6. In addition, all parts electrically connected with the common rail 5 are insulated and mounted through the insulating support 3. The arrangement form mainly aims at the condition that the length of a dead zone is long, a turnout fracture needs to be completely penetrated and eliminated when a current connection device at one turnout is independently arranged, or the arc-drawing requirements of a rail at the position of the turnout fracture and a boot are high.

In the method for using the current connecting device at the turnout, as shown in fig. 9, the rail driving device 2 is linked with the signal of the signal at the turnout or the working state of the switch 8. When this circuit had the vehicle to pass through (switch side strand switches on), switch department semaphore sent the side strand and switched on the signal, and goat 8 is in the side strand and switches on the state, and this embodiment is in operating condition. At the moment, the rail driving device 2 drives the current connecting rail 1 to act, so that the lower bent sections of the end elbows 4 on the current connecting rail 1 and the common rail 5 are overlapped and the straight sections are embedded to form physical and electrical continuity, the current connecting rail 1 is positioned in the working range of a vehicle return boot or a collector boot, and the reliable overlapping of the rail and the boot when the vehicle passes through is ensured. When this circuit does not have the vehicle to pass through (switch straight strand switches on), the semaphore sends straight strand switch on signal, and goat 8 is in straight strand switch on state, and this embodiment is in the excision state. The current connecting rail 1 is driven by the rail driving device 2 to move to a certain distance outside the free position range of the collector shoe or the return shoe, and the current connecting rail 1 is separated from the working range of the return shoe or the collector shoe of the vehicle, so that the passing of vehicles on other lines is not influenced.

Example two

The embodiment of the invention provides a current junction device at a turnout, which comprises a current junction rail 1, a rail driving device 2 and an insulating support 3, wherein the current junction rail 1 is positioned between two sections of common rails 5 and is electrically communicated with the common rails 5 through cables 7. The common rail 5 is a contact rail or a return rail. The current splicing rail 1 is connected with a rail driving device 2 through an insulating support 3, and the rail driving device 2 is used for driving the current splicing rail 1 and the insulating support 3 to move in a lifting and/or translation mode. The ends of the common rail 5 and the current connection rail 1 are provided with end elbows 4. The two end bends 4 on the left side of the current junction rail 1 are similar in construction to the bends of fig. 5-6, except that there is no splicing switch 6. A mechanical break exists between the two end bends 4 located on the right side of the current connecting rail 1. The end bend 4 is configured as shown in figure 7 with the width of the down bend being the same as the width of the straight section. All parts electrically connected with the common rail 5 are insulated and mounted by the insulating support 3. The arrangement mode mainly aims at the situation that the length of a dead zone is short, the current connection device at one turnout can eliminate the dead zone of all lines or special requirements on the electric subsection of the fracture position of the turnout are met. The mechanical fracture can be set to be a single-side fracture or a double-side fracture (the single-side fracture in the embodiment) according to actual engineering.

The method of using the present embodiment is the same as the first embodiment.
