Abstract
The invention relates to a 380 V switch cabinet maintenance car. The 380 V switch cabinet maintenance car comprises a car body, universal wheels connected to the lower portion of the car body, a handle connected to the side of the vehicle body, a hydraulic supporting module arranged on the car body and an overhaul platform connected to the top of the hydraulic supporting module. Rising and falling of the overhaul platform are achieved under the control of the hydraulic supporting module. The 380 V switch cabinet maintenance car further comprises a height limiting device, the height limiting device is movably connected between the car body and the overhaul platform, and the height of the overhaul platform is controlled by controlling the height of the hydraulic supporting module. Compared with the prior art, the 380 V switch cabinet maintenance car can control the height of the overhaul platform conveniently, thereby being applied to maintenance of 380 V switch cabinets. Due to the fact that when the overhaul platform reaches the maximum height, the included angle between hinged frames for forming the hydraulic supporting module is controlled to be 90 degrees through the height limiting device, even distribution of stress of the hydraulic supporting module in the horizontal direction and stress of the hydraulic supporting module in the vertical direction is achieved, and the service life of the hydraulic supporting module is prolonged.
Description
Technical field
The present invention relates to a kind of apparatus for examination and repair, especially relate to a kind of 380V switch cubicle tool car.
Background technology
In current capital construction electrical network project, the type switch cubicle top layer car formula switches such as 380 volts of GGD are higher apart from ground, and car formula switch weight is heavier, and operations staff requires great effort when operation car formula switch, and application point is difficult to control.Exist serious potential safety hazard, the dangerous phenomenon that while once there is operation, hurt sb.'s feelings in top layer switch landing ground, the inspection trolley that therefore needs development to adapt to top layer switching manipulation can be avoided the generation of hazard event and improve operating personnel's operating efficiency.
Application number is that 201110368868.3 Chinese patent discloses a kind of hydraulic elevating type tool car, hydraulic cylinder is vertically equipped with in middle at body frame, the piston rod top of hydraulic cylinder is provided with sprocket wheel pedestal, on sprocket wheel pedestal, fill sprocket shaft, on sprocket shaft, fill sprocket wheel, middle cross beam is established in middle at body frame, chain directive wheel is housed on middle cross beam, on supporting plate, on crossbearer and supporting plate lower cross frame, fill leading truck, on leading truck, symmetry fills two pairs of directive wheels, on in the gathering sill of directive wheel on body frame, lower slider, on supporting plate lower cross frame, fill adjusting screw(rod), one termination of adjusting screw(rod) is provided with crank, sprocket wheel connects supporting plate lower cross frame with chain by chain directive wheel, but this kind of tool car structure relative complex, and lifting position is unfixing, still can have problems in use.
Summary of the invention
Object of the present invention be exactly in order to overcome the defect that above-mentioned prior art exists, provide a kind of stressed evenly, the 380V switch cubicle tool car of long service life.
Object of the present invention can be achieved through the following technical solutions:
A kind of 380V switch cubicle tool car, comprise car body, be connected to car body below universal wheel, be connected to side body handle, be arranged on hydraulic pressure support module on car body, be connected to the inspection platform at hydraulic pressure support module top, under the control of hydraulic pressure support module, realize lifting, also comprise height limiting device, this height limiting device is movably connected between car body and inspection platform, by controlling the height of hydraulic pressure support module with the height of control inspection platform.
Described height limiting device is telescopic Flexible Connector, controls inspection platform and reach maximum height when Flexible Connector is straightened.
Described Flexible Connector comprises spring, rubber strip or mutually nested multiple-segment telescopic tube.
Described hydraulic pressure support module is by hydraulic control instrument and be the hydraulic support frame that the hinge frame of the variable-angle that crosses one another forms and form,
Described hydraulic control instrument is self-action or manual type controller, cuts with scissors the lifting of the angle control hydraulic support frame between frame by control, and when high resiliency connector is straightened, each angle cutting with scissors between frame is 90 °.
Described hydraulic control instrument by hydraulic cylinder, hydraulic pump and manually or automatically control piece form.
The lower surface of described inspection platform is provided with the slide rail that inspection platform is slided in the horizontal direction.
Compared with prior art, the present invention is owing to being provided with height limiting device, can conveniently control the height of inspection platform on the one hand, thereby be applied in the maintenance of 380V switch cubicle, the more important thing is, because inspection platform is when reaching maximum height, the angle respectively cutting with scissors between frame of controlling formation hydraulic pressure support module by height limiting device is 90 °, make hydraulic pressure support module in the horizontal direction and vertical direction distribution of force even, extended the useful life of hydraulic pressure support module.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 is that inspection platform, 2 is that hydraulic support frame, 3 is that car body, 4 is that universal wheel, 5 is that handle, 6 is that height limiting device, 7 is hydraulic control instrument.
