Description
Technical field
The utility model belongs to bridge inspection field, is related to a kind of drive control powered by DC power supply to inspection vehicle
Device.
Background technique
It is that bridge inspection maintenance personal provides job platform during bridge inspection and maintenance that bridge inspection vehicle, which is a kind of, is equipped with
Bridge inspection equipment and maintenance equipment, detect for flowing checking or maintain the special engineered vehicle of operation.It can be with
When shift position, allow bridge inspection maintenance personal safe, fast, efficiently enter job position carry out upkeep operation.Bridge at present
Beam inspection vehicle has become large bridge especially steel structure bridge and carries out the indispensable equipment of routine servicing maintenance.
Suspension type beam bottom checks vehicle as bridge associate member and is permanently suspended on bridge bottom, because of the power supply mode of battery
It is better than trolley in terms of weatherability, reliability, generator is increasingly praised highly by user, but driving device mostly uses exchange
Motor.
The country mostly uses battery, inverter, this driving method of AC converter.Because inverter is DC communication
Conversion equipment checks vehicle power supply to entire, and power is big, and weight weight takes up space, and price will also maintain, so needing
Find a kind of succinct effective drive control mode.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of inspection vehicle for using DC power supply as power source,
The drive dynamic control device powered by DC power supply to inspection vehicle.

It is a kind of by DC power supply to check vehicle power drive dynamic control device, check vehicle include car body, walking mechanism and
Electric cabinet, the walking mechanism are fixedly mounted on the car body, and bridge bottom is equipped with multiple suspenders, and the walking mechanism drives institute
Bridge bottom can be removably mounted within by the suspender by stating car body, and driving walking mechanism is equipped in the electric cabinet and is carried out
The control device of transmission, the control device include DC power supply, DC converter, control unit, with dc power interface
Frequency converter and motor, the DC power supply are that frequency converter and DC converter are directly powered, and are powered to control unit, the control
Unit provides input and control signal, controls positive and negative rotation and the start stop signal of frequency converter, and the frequency converter carries out speed to motor
Control, the motor drives walking mechanism walked, gone up and down, expanding-contracting action.
Further, the motor is ac three-phase asynchronous motor.
Further, described control unit is control switch.
Further, described control unit is that control switch is combined with the unit with logic control.

Mechanism drives the car body that can removably mount within bridge bottom by the suspender, and driving row is equipped in the electric cabinet
The control device that mechanism is driven is walked, the control device includes DC power supply, DC converter, control unit, band direct current
The frequency converter and ac three-phase asynchronous motor of power interface, the DC power supply are that frequency converter and DC converter are directly powered,
It powers to control unit, described control unit provides input and control signal, controls positive and negative rotation and the start stop signal of frequency converter, institute
It states frequency converter and speed control is carried out to ac three-phase asynchronous motor, the ac three-phase asynchronous motor drives walking mechanism to be gone
It walks, go up and down, expanding-contracting action.
Optionally, described control unit is control switch.
Optionally, described control unit is that control switch is combined with the unit with logic control.
Optionally, the DC power supply is electrochmical power source.
Optionally, the DC power supply is battery.
Optionally, the DC power supply is capacitor.
Finally, it is stated that preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
The range of restriction.
