CN203638610U - Single-phase low tension ground rack vehicle rails - Google Patents

Abstract

The utility model discloses single-phase low tension ground rack vehicle rails which comprise ground rack vehicle rails buried underground, wherein an electric power transmission belt parallel to the vehicle rails is mounted on a foundation between the two vehicle rails. Copper bars are adopted by the electric power transmission belt, the copper bars are fixedly connected with square steel buried in the foundation, and an insulating layer is arranged between the square steel and the foundation. After the single-phase low tension ground rack vehicle rails are adopted, due to the fact that the two vehicle rails supporting a ground rack vehicle are connected to null and are communicated with the ground directly, no insulation protection is needed, square steel tubes only need to be embedded after slotting is carried out on cement floors between the two vehicle rails after an insulation layer is arranged, the copper bars are laid on the square steel tubes, and the laid copper bars serve as live wires to supply power for the rack vehicle. After the ground rack vehicle obtains an AC36V low tension power supply, the AC36V low tension power supply is boosted into an AC220V power supply through a single-phase boosting transformer, the AC220V power supply is output through a single-phase frequency converter, input connection is changed through a YZD series motor, and the AC220V power supply is used for running. Labor and materials are saved, safety is good, and rail supporting intensity is high.

Description

A kind of single-phase low pressure track car track

Technical field

The utility model relates to the low-pressure electric transport trolley track on the ground such as factory floor, goods station.

Background technology

The power supply mode of general track car track, for getting three phase mains after three phase transformer is adjusted to AC36V power supply, is supplied with and is laid on three underground guide rails, and actuating device is supplied with in the power taking from guide rail again of track car after step-up transformer boosts.The drawback of in use finding this electric power-feeding structure mode is a lot, because each guide rail is all charged, article three, guide rail all needs to do to insulate, thereby cost is too high, the stability of two guide rails of load capacity is too poor, simultaneously three guide rails are all charged also very easily causes short circuit, and the track power supply mode of long distance is easy to produce loss in voltage, makes the operation of track car produce fault.

Utility model content

The utility model provides a kind of single-phase low pressure track car track, the problem existing to solve prior art.

The utility model object solves in the following manner: this single-phase low pressure track car track comprises and be embedded in underground track car track, it is characterized in that installing on the ground between two tracks an electric power load-transfer device parallel with track.

Described electric power load-transfer device adopts copper bar, and described copper bar is connected with the square steel being embedded in ground, between square steel and ground, is provided with insulating barrier.

The technological advance that the utility model is obtained: adopt after the single-phase low pressure track car track of the utility model structure; be zero because two track tracks of support track car connect respectively; straight-through the earth; do not need to do insulation protection; implant square steel tube and only need slot after doing insulating barrier on the cement flooring between two tracks; in square tube, lay copper bar, the copper bar of laying is as the live wire power supply of rail vehicle.Track car obtains after AC36V low potential source, after individual event step-up transformer boosts as AC220V power supply, then through the output of individual event frequency converter, changes input connection by YZD serial motors, gets the operation of AC220V power supply.Labor and material saving, safety is good, and rail supported intensity is high.
