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 vehicle type such as 380 volts of ggd switch is higher away from ground, and vehicle type
Switch weight is heavier, and operations staff is laborious when operating vehicle type switch, and application point is difficult to hold.There is severe compromise,
When once occurring to operate, top layer switched the dangerous phenomenon hurted sb.'s feelings on landing ground it is therefore desirable to develop adaptation top layer switching manipulation
Inspection trolley is avoided that the generation of hazard event and the work efficiency improving operator.
The Chinese patent of Application No. 201110368868.3 discloses a kind of hydraulic elevating type tool car, in body frame
Between locate, vertically equipped with hydraulic cylinder, above the piston rod of hydraulic cylinder, to be provided with sprocket wheel pedestal, dress sprocket shaft on sprocket wheel pedestal, on sprocket shaft
Dress sprocket wheel, set middle cross beam in the middle of body frame, on middle cross beam equipped with chain guide wheel, crossbearer and supporting plate lower cross frame on supporting plate
Upper dress leading truck, leading truck symmetrically fills two to directive wheel, directive wheel upper and lower slip in the gathering sill on body frame, in supporting plate
Adjusting screw rod is filled on lower cross frame, a termination of adjusting screw rod is provided with crank, and sprocket wheel chain connects supporting plate by chain guide wheel
Lower cross frame, but this kind of maintenance bassinet structure is relative complex, and lifting position is not fixed, and still can have problems when using.
Content of the invention
The purpose of the present invention is exactly to overcome the defect of above-mentioned prior art presence to provide a kind of uniform force, use
The 380v switch cubicle tool car of life-span length.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of 380v switch cubicle tool car, including car body, is connected to universal wheel below car body, is connected to side body
Handle, the hydraulic pressure support module being arranged on car body, the inspection platform being connected to hydraulic pressure support module top, in hydraulic pressure support mould
Realize under the control of block lifting, also include height limiting device, this height limiting device is movably connected in car body and inspection platform
Between, control the height of inspection platform by controlling the height of hydraulic pressure support module.
Described height limiting device is telescopic Flexible Connector, controls maintenance flat when Flexible Connector is straightened
Delta is to maximum height.
Described Flexible Connector is spring, rubber strip or mutually nested multiple-segment telescopic tube.
The hydraulic pressure that the hinge frame by hydraulic control instrument and in the variable-angle that crosses one another for the described hydraulic pressure support module forms props up
Support forms,
Described hydraulic control instrument is self-action or manual type controller, controls hydraulic pressure by controlling the angle between hinge frame
The lifting of bracing frame, when high resiliency connector is straightened, the angle between each hinge frame is in 90 °.
Described hydraulic control instrument by hydraulic cylinder, hydraulic pump and manually or automatically control piece constitute.
The lower surface of described inspection platform is provided with the slide rail making inspection platform slide anteroposterior in the horizontal direction.
Compared with prior art, the present invention, due to being provided with height limiting device, on the one hand can conveniently control maintenance flat
The height of platform, thus apply 380v switch cubicle maintenance in it is often more important that, because inspection platform is when reaching maximum height,
Control the angle between each hinge frame constituting hydraulic pressure support module to be in 90 ° so that hydraulic pressure support module by height limiting device
In the horizontal direction and vertical direction distribution of force uniformly, extend the service life of hydraulic pressure support module.
Brief description
Fig. 1 is the structural representation of the present invention.
In figure, 1 is inspection platform, 2 is hydraulic support frame, 3 is car body, 4 is universal wheel, 5 is handle, 6 is height limit
Device, 7 be hydraulic control instrument.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.

Inspection platform 1, under the control of hydraulic pressure support module realize lifting.In addition, also include height limiting device 6, this height
Degree stopping means 6 are movably connected between car body 3 and inspection platform 1, control inspection by controlling the height of hydraulic pressure support module
The height of equating platform.The lower surface of inspection platform 1 is provided with the slide rail making inspection platform 1 slide anteroposterior in the horizontal direction.
Using height limiting device 6 be telescopic Flexible Connector, be spring, rubber strip or mutually nested more piece
Telescoping tube, controls inspection platform to reach maximum height when Flexible Connector is straightened.
The hydraulic support frame 2 that the hinge frame by hydraulic control instrument 7 and in the variable-angle that crosses one another for the hydraulic pressure support module forms
Composition, hydraulic control instrument 7 be self-action or manual type controller, by hydraulic cylinder, hydraulic pump and manually or automatically control piece constitute.
Control the lifting of hydraulic support frame by controlling the angle between hinge frame, when high resiliency connector is straightened, between each hinge frame
Angle is in 90 °.
Due to being provided with height limiting device 6, on the one hand can conveniently control the height of inspection platform 1, thus applying
380v switch cubicle maintenance in it is often more important that, because inspection platform 1 is when reaching maximum height, controlled by height limiting device 6
