Described lifting platform also comprises the crane being connected to scissor-type on the downside of described support platform, the longitudinal center position of described platform trailer upper flat plate is fixed in the lower end of crane by base, the side, lower end of crane is connected with pulley, base has corresponding chute, pulley can be free to slide in chute.
Described crane is by oil cylinder as dynamical element, and the upper end of oil cylinder is fixed on crane, and lower end is fixed on described base.
Described base there is travel switch spacing when crane is drawn in.
Described support platform comprises the supporting bracket that level is fixed on described crane upper end; the upper surface of supporting bracket has the soft supporting pad for the protection of on-load switch; one end of supporting bracket is connected with backing plate; on backing plate, broad ways is fixed with rotatable rotating shaft by bearing; rotating shaft is hinged with the bedplate for firm demand switch; the back-up block when outside of rotating shaft has on-load switch upright on backing plate; fastening bolt when bedplate having on-load switch upright and limited post, supporting bracket has fastening bolt during on-load switch horizontal positioned.
Described cable hank assembly has two groups, and they are placed in longitudinal both sides of platform trailer upper flat plate; Often organize the support that cable hank assembly comprises three cable hanks and fixes them, the disk of cable hank both sides there is connecting axle overhanging vertically, flexible cable is around on the connecting rod between two disks, have bearing and corresponding bearing pedestal outside connecting axle, there is the connecting hole about connecting axle symmetry the both sides of bearing pedestal; There is the fixed head corresponding with bearing pedestal the upper end of support, fixed head there are the screw rod corresponding with connecting hole position or through hole, screw rod is through connecting hole, then be fastenedly connected by corresponding T-shaped nut, or the through hole on bearing pedestal on connecting hole and bracket fixing plate is fixed by latch, and the lower end of support and the upper flat plate of described platform trailer are detachably fixed.。
The side of described support is connected with the internal thread sleeve pipe perpendicular to described cable hank, and supporting in internal thread sleeve pipe have corresponding snap close bolt, to realize the lock function to cable hank.
The inner side of described disk is connected with the cutting ferrule for placing flexible cable and on-load switch connection end.
Described platform trailer also comprises the vehicle frame being connected to described dull and stereotyped downside, the downside of vehicle frame is connected with two groups, the front and back wheel connected by load-bearing axle, front load-bearing axle two ends between two front-wheels are fixed by bearing and vehicle frame, the two ends symmetry of this load-bearing axle is hinged with steering component, middle position free drawbar; Steering component comprises the steering spindle that outer end is connected with front-wheel, the inner is connected with front load-bearing axle, and the sidewall of steering spindle stretches out joint backward, is connected with steering linkage between the end of joint and the rear end of draw bar.
Described vehicle frame is fixed with hydraulic pump and the storage battery for its power supply.
The on-load switch and flexible cable of building bypass needs are placed on same liftable mobile platform by the present invention, rising and the decline of crane is controlled by oil cylinder, sufficiently high safe distance can be formed, effectively can solve on-load switch security protection problem, crane takes up room little when drawing in, be convenient to carrying and store.The method of current erection on-load switch mainly comprises and is suspended from electric pole by on-load switch, or use bypass load-switch automobile, the former wastes time and energy because on-load switch is heavier, operation inconvenience, and because of safe altitude inadequate, complicated safety prevention measure need be carried out to on-load switch, and the latter is owing to depending on vehicle, higher to operation field space requirement.On-load switch can be risen to the height of safe enough by remote control by this mobile platform, and simple operation is time saving and energy saving, and without the need to taking security protection to it.
When this mobile platform is provided with corresponding on-load switch operating state and non operating state time safe displacement structure.Be in erectility during on-load switch work, the support platform of crane upper end is provided with the bracing frame be made up of rotating shaft, bedplate and supporting pad, fastening bolt, firm with guaranteed load switch.When on-load switch is in non operating state, by rotating shaft, on-load switch is put in supporting bracket, simultaneously by soft supporting pad and fastening bolt fastening.
In order to safety features, the mounting seat bottom crane is provided with travel switch as automatic protection blocking device.When crane drops to certain altitude, this locking device meeting trigger protection signal, this signal makes oil cylinder stop contractive action immediately, prevents from not observing position in decline process because of staff, causes the excessive gathering of crane, causes the problem of device damage.
Cable hank assembly realizes modularization assembling, easy accessibility.Each cable hank is independently installed on support, fixes, need not can complete being fixedly connected with between cable hank with support by external tool respectively by T-shaped nut or latch and support.Each cable hank can be pulled down from support efficiently when not using, deposit in qualified storehouse.Support is fixed by bolt and platform trailer, and dismounting is also very convenient.Improve fail safe and save parking space.
The course changing control of platform trailer adopts steering geometry, using draw bar as steering operation bar.Draw bar is equivalent to pitman arm, its bilateral symmetry is connected with steering spindle and steering linkage, when front tows the vehicle changing Lane of mobile platform or turns, the Impact direction of draw bar changes, produce rotating torque, this moment is passed to front-wheel steer axle by left and right steering linkage, completes the go to action of vehicle.
A lot of events in operation only need to build small-sized bypass, do not need large-scale cloth cable car to provide a large amount of flexible cable.As from the interim power taking of overhead transmission line to ring main unit supply project, required cable only has tens meters, in this case, the present invention completes bypass operation with regard to main equipments such as alternative cloth cable cars, greatly can increase flexibility, use manpower and material resources sparingly cost, increases work efficiency.Integration Design of the present invention overcome prior art because working truck is many, equipment is huge can not adapt to that urban power distribution network space is crowded, the construction operation environment of street canyon.
In sum, the present invention adopts the mentality of designing of integrated, mobile, facilitation, by the integration of equipments such as bypass load-switch, flexible cable on the mobile platform with elevating function, when needs use, utilize the drag and drop of repairing Work tool can start working to job site, effectively economize on resources, expand the scope of application of bypass operation.
