Description

Horizontal double-rod split-rotating power receiving pole for bus and tram

technical field

The invention relates to a power receiving device for trams in the technical field of transportation, in particular to a lateral double-rod type split-rotating power receiving pole for bus trams.

Background technique

At present, the bus or trolley bus using supercapacitor energy storage in the field of urban public transportation has entered commercial operation or trial operation, and its vehicle has a small amount of supercapacitor, so the vehicle is light in weight, flexible and fast, and only needs to use the terminal and Short-term fast supplementary charging when parking at some intermediate stops can drive uninterrupted on the entire operating line. Since this technology can mostly cancel the original trolleybus overhead power supply contact wire network or feeder wire network along the bus line, only a section of contact wire network dedicated to charging is reserved above the station area of the terminal station and some intermediate stops. The trolleybus is separated from the traditional form of overhead power supply contact wire network and the driving constraints of the roof collector pole and collector slide shoe, so the collector slide shoe will not jump off the wire during driving and cause power failure and stoppage. Accidents such as traffic jams, because there is no overhead power supply catenary network, make the landscape above the city streets beautified, and at the same time, it can reflect the characteristics of trolleybus driving with low noise, no emission pollution, fast start and uphill.

After literature search, it was found that Chinese patent number: ZL03142212.8, named: double-wire pantograph type trolley bus collector pole, the invention patent self-described as "including: chassis, collector pole, bow spring, balance bar, Bow head seat bar, cylinder, bow top bar, bow top conductive slide plate, insulating seat, insulating rod, bow head spring; bottom frame, collector rod, balance bar, bow head seat bar four constitute a parallel In the quadrilateral linkage mechanism, the bow top conductive slide plate is separated by an insulating rod in the middle to form a double current collector and is supported and fixed on the bow top cross bar through an insulating seat. Connected by the bow head spring, when the cylinder on the underframe and the bow spring make the lower arm swing, the conductive slide plate on the top of the bow will be raised and lowered. The invention has less constraints on the vehicle wire net, good pantograph-catenary contact performance, and high current-receiving and stable power , work safely and reliably, and can access the network while the tram is running." Although the invention adopts the two-wire pantograph collector pole power receiving method with the tram roof being lifted and lowered, its automatic lifting and lowering of the two-wire pair has less constraints on the network connection, and can be used for the two-wire power receiving and charging of the rechargeable trolleybus in the station area. ; but from its technology "parallelogram linkage" and "when the cylinder on the bottom frame and the bow spring make the lower arm swing, the conductive slide plate on the top of the bow is raised and lowered", and "it can enter and exit the net while the tram is running" It can be seen that the trolleybus collector pole moves up and down when it is working, and its bow-top conductive slide receives power from the special charging feeder network above the vehicle driving road in the overhead station area. Whether it is drawn out through the electric pole on the sidewalk or on the shed of the bus waiting station on the street still restricts the driving of other super-high vehicles such as some engineering vehicles and special transport vehicles, and the charging type trolleybus waiting Therefore, the station area of the station is not beautiful enough; moreover, the parallelogram linkage mechanism composed of the collector pole, the balance pole, the bow head seat crossbar, etc. makes the form and structure of the collector pole complicated, so this kind of technology has defects, and the scope of application is still restricted.

Two or The two sets of pantographs are respectively supported on two long and short bow support rods through insulators, and the position of the pantograph supported on the longer bow support rod is close to the upper end of the bow support rod. The pantograph bodies on the two bow head support rods are insulated from each other to form double current collectors and electrically connected to the on-board power storage control device or/and charging device of the bus. Under the action of the driving device, they can be rotated and lifted in the lateral plane perpendicular to the driving direction of the bus, so that the pantographs on it can be freed from the constraints and influences of the same fixed body, and they can lean towards each other freely. And closely contact the feeder wires with different distances in the lateral direction of the double feeder wires to receive power.

The two sets of bow-raising driving devices may be a combination of a cylinder or a motor and a gear reduction box or an electric push rod.
