Description

A dual power supply device for electric collectors for driving

technical field

The utility model relates to the electrical field, in particular to a dual power supply device for a traveling electric collector in a circuit with a long trolley line and poor contact of a collector.

Background technique

In the process of our daily use of the crane, we use the crane to lift the equipment when maintaining the equipment. During the lifting process, the crane loses power due to poor contact between the collector and the trolley line, causing the equipment to hang in mid-air and cannot move. It will bring great potential safety hazards to people and equipment.

In addition, in the case of frequent maintenance due to driving failures, the driving distance from the ground is at least 9 meters high, making maintenance difficult and bringing great safety hazards to maintenance personnel. After inspection, the cause of the fault is that the trolley line is too long and the track is not smooth enough, the power supply phase is broken due to the wear of the collector and the deformation of the trolley line, resulting in the failure to provide power to the driving, and the driving failure cannot be used normally.

Utility model content

The purpose of this utility model is to provide a device with dual power supply for the electric collector of the traveling vehicle. By adding a current collector to the traveling vehicle, the device can make the trolley line and the collector contact well on the uneven track, and the driving is not easy. The power will be cut off, which provides a strong guarantee for the maintenance of equipment in the production system.

The purpose of this utility model is achieved through the following technical solutions.

A dual power supply device for electric collectors for driving, including a trolley wire frame, on which two collectors are arranged, each collector is respectively connected to the trolley line on the trolley wire frame, and the two collectors The electrical appliances are connected through jumper cables, and the jumper cables are connected to the driving; the collectors are connected to the fixed plate through the collector hanging plate for positioning.

Preferably, the fixing plate is fixed on a support on the ground, and the connection between the fixing plate and the collector hanging plate is connected through hanging wires.

Preferably, the collector hanging plate is fixed on the middle side wall of the collector and extends to the lower end thereof.

Preferably, the two collector power lines are respectively connected to the three-phase power lines of the trolley line, and the three-phase power lines of the two collectors respectively correspond to the three-phase power lines of the trolley line.

Compared with the prior art, the beneficial effects of the utility model are:

1) In this transformation, the wiring power supply is to supply power to the trolley line, and the trolley line is to provide power to the collector. Through the parallel connection of the two power collectors, the power supply is provided to the driving, so that the dual power supply can supply power to the driving and power the driving. The fault caused by it provides a strong guarantee for continuous power supply.

2) Dual power supplies are used to provide power to the trolley line, which effectively avoids the potential safety hazards caused by the failure of the vehicle to stop during the operation of the vehicle and equipment.

3) By utilizing this device, the driving can be maintained more conveniently, the number of maintenance can be reduced, and manpower and material resources can be greatly saved.

4) Using this device can improve the maintenance efficiency and improve the reliable operation of the production system.

5) The transformation cost is low and the manufacture is simple, which brings convenience to the stable power supply and rapid maintenance of the vehicle, and brings convenience to enterprises, chemical industries, and vehicle maintenance.
