Background technology
At present, when utilizing the bigger Heavy Product of handbarrow delivery volume, at first utilize crane with it during according to lifting the safest attitude lift on the handbarrow.
When delivering heavier higher goods, if its attitude on handbarrow is not suitable for carrying, this will cause some troubles in handling process:
The above-mentioned bigger heavy article of volume that lifted on the handbarrow; Usually be difficult on this handbarrow, change significantly the attitude that oneself is handled upside down; For example: change it at the inclined degree that is handled upside down on the instrument; And can the change of this inclined degree tend to relate to and improve the stability that is handled upside down thing with it through lower doorframe height and lower the center of gravity.
Summary of the invention
The present invention's purpose: propose a kind of technical scheme that addresses the above problem.
In order to realize the present invention, intend the technology below adopting:
The present invention includes: load-bearing right angle pallet; The horizontal displacement worm screw that links to each other with the position, right angle of load-bearing right angle pallet through the right angle end points; Through supporting that the summit links to each other with the top of load-bearing right angle pallet and through supporting the flexible hydraulic gear that basic point links to each other with the pedestal that cooperates with the manual pallet car, be running-fit on the hold-down arm of the head and the tail two ends of horizontal displacement worm screw and the front and back of the pedestal of following the manual pallet car to cooperate and concern;
It is characterized in that:
Above-mentioned horizontal displacement worm screw realizes steadily changing the loading attitude that is handled upside down article through right angle end points and flexible hydraulic gear through supporting both driven in common load-bearing right angle pallets of summit.
The present invention and prior art characteristics relatively:
Because the horizontal displacement worm screw passes through to support the process of driven in common load-bearing right angle, summit pallet through right angle end points and flexible hydraulic gear; Just make in the variation overall process at the angle of inclination that is handled upside down product; All the time be in stable " triangle " supporting construction, this is just for realizing that steadily changing the loading attitude that is handled upside down product has created condition.
The specific embodiment
Further specify below in conjunction with accompanying drawing,, obviously, the present invention includes as the overview of one embodiment of the invention:
Be arranged on the pedestal 1 on the tray carriage W, the length of this pedestal 1 is 1.6 meters, and wide is 1 meter, and height is 8 centimetres, and it adopts the casting of Q235 high strength steel material to make.
Electrical motor 2 (power is 800 watts-1000 watts) is arranged on the end of pedestal 1, is the direct driving force that drives the 3 positive and negative rotations of horizontal displacement worm screw, promptly passes through the direct driving force of the forward and backward displacement of horizontal displacement worm screw 3 driving right angle end points C.
The main effect of displacement is to drive load-bearing right angle pallet 5 slide displacement before and after pedestal 1 upper surface is implemented before and after the right angle end points C.
It is 1.5 meters that above-mentioned horizontal displacement worm screw 3 is adopted length, and the 40Cr material that reference diameter is 35.5 millimeters is processed.
It is angles of inclination of adjustment load-bearing right angle pallet 5 that the present invention adopts the main purpose of a pair of flexible hydraulic gear 4, why the purpose that has adopted a pair of flexible hydraulic gear 4 on this position be since this a pair of hydraulic efficiency gear in flexible process very easily in both synchronous and suitable pulsation-free displacements of realization.---the single bearing capacity 40KN of this hydraulic telescopic machanism 4, extend 1.8 meters fully, be 1 meter after shrinking fully.
Load-bearing right angle pallet 5 is 2 meters by height, and wide is 1 meter facade, and the length vertical with this facade is 1 meter, and wide is that 1 meter horizontal surface constitutes, and it is 1 centimetre 45 steel and the reinforced rib that has same material in the part of the force that these parts all adopt thickness.
Three nodes that are provided with in the middle of the present invention: support summit A, support basic point B and right angle end points C and be the most conventional rotary flexible connection point.
The load-carrying ability that can carry tray carriage W of the present invention is generally the 3-5 ton.
The product weight that load-bearing right angle pallet 5 carries among the present invention should not be higher than 4 tons, and it is high 3 meters that its volume upperlimit should be no more than long 1.5 meters wide 1.5 meters X of X.
For example: just in the volume range of the invention described above qualification, its weight is 1.3 tons (also in framework of the present definition) to the overall dimensions that are of a size of the high 2.7 meters XGN2-12 10kV switch cubicle of long 1.2 meters wide 1.2 meters X of X.
Use when of the present invention:
During power distribution room doorframe through door high 2.4 meters (the routine regulation of GB) when the present invention loads above-mentioned XGN2-12 10kV switch cubicle through tray carriage W; Can't directly this switch cubicle be transported power distribution room through doorframe; The angle of inclination of switch cubicle only changes; Make its bottom-to-top-height be lower than doorframe, could transport power distribution room through this doorframe.
When desire changes above-mentioned bottom-to-top-height; As long as driving horizontal displacement worm screw 3 through electrical motor 2 rotations is rotated in the forward; Drive right angle end points C towards direction displacement away from electrical motor 2; Let flexible hydraulic gear 4 shrink simultaneously, can the height of cargo-carring above-mentioned switch cubicle in the present invention be added that height of the present invention adds the summation height of tray carriage W height and be lower than 2.4 meters of above-mentioned doorframe height.
