Description

TECHNICAL FIELD

[0001] The utility model discloses a rail transit equipment technical field, concretely relates to a rail transit vehicle pantograph overhauling auxiliary support device. BACKGROUND

[0002] The rail transit vehicle pantograph is one of important components of the vehicle power supply system, and is mainly used for connecting the direct current 1500V of the contact network into the vehicle system to supply power to the vehicle equipment. If the pantograph fails during the operation of the vehicle, not only the current collection of the vehicle is interrupted, but also the contact network may be damaged in a large area. Therefore, it is necessary to regularly overhaul and maintain the pantograph.

[0003] At present, the pantograph overhaul is mainly in the mode of preventive planned repair and auxiliary fault repair. The carbon slide plate, bow head spring, bow lifting device and soft connecting wire of the pantograph need to be replaced within a certain period, and the ADD air pipe and bow head bracket need to be replaced due to faults. Since the replacement of parts, the pantograph falling height is only 310mm, and some parts are blocked, so the pantograph head needs to be lifted manually during the replacement of parts. Since the weight of the pantograph head exceeds 15kg, the long-time lifting of the head is prone to dangerous events and restricts the efficiency of the overhaul, so it is necessary to design a rail transit vehicle pantograph overhaul auxiliary support device which has strong practicability and can stably lift the head to improve the efficiency of the overhaul.

Although the device can increase stability, it still has the following disadvantages in actual use:
