Abstract
The utility model relates to a hydraulic hand cart which is used for loading and unloading as well as transporting goods and adopts a hydraulic power-assisted and elevating function. The utility model is composed of a hydraulic oil cylinder, a push rod, a lifting arm, a supporting plate, a handrail, a pedal, a turn knob, tyres, a carrier frame, etc., wherein the hydraulic oil cylinder, the push rod, the pedal and the turn knob form a hydraulic system, and the push rod is connected with a lifting arm set, wherein the lower end of which is connected the carrier frame through a hinge and the upper end of which is connected with the supporting plate. The supporting plate can move up-and-down along with the lifting arm set under the action of the hydraulic system, and the handrail is connected with the carrier frame and can be folded. The utility model is characterized in that a rubber plate is arranged in the middle of the supporting plate and a plurality of plug pin holes are arranged on both sides of the supporting plate; a plug pin locking flexible oil tank is plugged in the plug pin holes. The utility model not only has the advantages of reducing labor intensity and improving labor efficiency, but also can take and place relatively heavy articles in high places under the conditions of no power loading and unloading device and few people, bringing convenience for actual work.
Description
Technical field
The utility model belongs to a kind of dolly that is used for the handling goods, relates to the four-wheel hydraulic trolley of loading and unloading field operations collapsible fuel tank.
Background technology
The existing dolly that is used to load and unload the field operations collapsible fuel tank, the supporting plate of bearing goods mostly is fixed type, lacks the height regulatory function.Under the situation of unpowered handling equipment, have only to carry on to carry off and realize by manpower, so, under the few situation of personnel, can't work.Cause manual work intensity big, waste time and energy.Supporting plate mostly is rigid plate in addition, at rugged ground running, easily causes unbonded collapsible fuel tank to skid off outside the car after the oil tank entrucking.
Summary of the invention
The problem that the utility model need solve is to propose a kind of adjustable and difficult hydraulic trolley of sliding in oil tank loading back of supporting plate height of carrying oil tank.
For addressing the above problem, the utility model is taked hydraulic booster and elevating function, is made up of hydraulic ram, push rod, lift arm, supporting plate, handrail, pedal, knob, tire, carriage etc.Hydraulic ram, push rod, pedal, knob are formed hydraulic efficiency pressure system, and push rod links to each other with lift arm, and the lift arm lower end links to each other with carriage by hinge, and the upper end links to each other with supporting plate, and supporting plate can move up and down along with lift arm under the hydraulic efficiency pressure system effect.Handrail links to each other with carriage, can fold.Adopt rubber plate in the middle of the supporting plate or some pin holes are arranged, plug the latch locking collapsible fuel tank in the supporting plate both sides.
The utility model has reduced labour intensity, improve efficiency, can be implemented under the fewer again situation of unpowered handling equipment, personnel, picked and placeed heavier eminence article relatively, can prevent simultaneously the problem of laden collapsible fuel tank slippage again, bring convenience to real work.
Description of drawings
Structural representation when Fig. 1 is the hydraulic trolley expansion;
Fig. 2 is hydraulic trolley structural representation when folding.
The specific embodiment
As shown in Figure 1, the utility model is made up of hydraulic ram 1, push rod 2, lift arm 3, supporting plate 4, handrail 5, pedal 6, knob 7, tire 8, carriage 9 etc.Hydraulic ram 1, push rod 2, lift arm 3, pedal 6, knob 7 are formed hydraulic efficiency pressure system, and wherein knob 7 links to each other with hydraulic ram 1, and push rod 2 links to each other with lift arm 3, and lift arm 3 lower ends link to each other with carriage 9 by hinge.Lift arm 3 upper ends link to each other with supporting plate 4, and supporting plate 4 can move up and down along with lift arm 3 under the hydraulic efficiency pressure system effect.Handrail 5 links to each other with carriage 9, can fold.Four tires 8 that feed flow presses dolly to roll are equipped with in carriage 9 belows, and tire 8 is an inflatable.Adopt rubber plate in the middle of the supporting plate or some pin holes are arranged, plug the latch locking collapsible fuel tank in the supporting plate both sides.
Hydraulic principle is as follows: clickwise knob 7, jam on pedal 6 downwards with pin, and pressure oil enters rodless cavity via the hydraulic control one-way valve in the hydraulic ram 1 and promotes push rod 2, makes on the push rod 2 and moves, thereby drive lift arm 3 upward movements, and supporting plate 4 increases.At this moment, the oil of cylinder rod chamber flows back to oil cylinder 1 from change-over valve under push rod 2 effects.Otherwise, left-hand revolution knob 7, pressure oil promotes piston from oil cylinder 1 rod chamber and hauls push rod 2 declines, moves downward thereby drive lift arm 3, supporting plate 4 descends thereupon, also opens the oil of hydraulic control one-way valve oil cylinder rodless cavity simultaneously and get back to oil cylinder 1 via hydraulic control one-way valve, change-over valve under the piston pushing.
The working process of hydraulic trolley is: unload when getting collapsible fuel tank from eminence, at first, clickwise knob 7, with the downward pedal 6 of pin, under the hydraulic efficiency pressure system effect, move on the push rod 2, thereby drive lift arm 3 upward movements, when making supporting plate 4 be elevated to collapsible fuel tank to deposit height, on the supporting plate 7 of hydraulic trolley in the collapsible fuel tank horizontal sliding, then, left-hand revolution knob 7 need not be with the downward pushes pedals 6 of pin, under supporting plate 4 self gravitation effects, make supporting plate 4 drop to nadir, plug the latch locking collapsible fuel tank, can transport collapsible fuel tank.Otherwise, when depositing collapsible fuel tank toward eminence, at first, collapsible fuel tank is transported to the downside of storeroom, clickwise knob 7, with the downward pushes pedals 6 of pin, under the hydraulic efficiency pressure system effect, move on the push rod 2, thereby drive lift arm 3 upward movements, make supporting plate 4 be elevated to collapsible fuel tank and deposit when height, collapsible fuel tank horizontal sliding from the supporting plate 4 is got final product to the storeroom.Left-hand revolution knob 7, under supporting plate 4 self gravitation effects, supporting plate 4 automatic lowerings are to nadir.
When hydraulic trolley is finished using, supporting plate 4 is adjusted to nadir, handrail 5 is folding, as shown in Figure 2, makes hydraulic trolley be easy to deposit.
