Abstract
A handcart-type general-purpose forklift uses two hydraulic and pneumatic cylinders with same bores and same strokes and the two hydraulic and pneumatic cylinders combine reasonably to have the function of expanding the strokes to twice strokes of a single cylinder, and the expanded strokes are suitable for the needs of the operation of forklifts. The handcart-type general-purpose forklift also solves the problems that the handcart-type general-purpose forklift uses cylinders with short strokes to combine to obtain large strokes, thereby reducing costs of big forklifts with large strokes and reducing occupied spaces of single cylinders with large strokes. The handcart-type general-purpose forklift comprises a storage rack, a fork frame, a portal frame, steel wire ropes, pulley wheels and hydraulic and pneumatic cylinders. The handcart-type general-purpose forklift is controlled by two hydraulic and pneumatic control valves, thereby being easy to use and worthy of generalizing and applying.
Description
Technical field
The present invention relates to a kind of general fork truck of handcart-type.
Background technology
Fork truck as a kind of mobile hoist-transportation machines, because it has good mobility and versatility, therefore
Be suitable for that cargo type is more, goods amount big and must department that is collecting and distributing rapidly and having enough to meet the need use, become port and pier, railway station and warehouse
The indispensable instrument of the departments such as goods yard, logistics company.
The content of the invention
A kind of general fork truck of handcart-type of the present invention, its feature is：1st, fork truck pulls shelf using steel wire rope；2nd, adopt
Two double acting liquid (gas) cylinder pressures carry out effectively connection, are allowed to the expanded functionality with cylinder body stroke.Such as the row of two little cylinder bodies
Journey is respectively 1000mm, after two liquid (gas) cylinder pressures are connected, then can realize total kilometres 2000mm.So as to realize waiting stroke shape
Under state, the cost of investment of fork truck is saved to greatest extent, reach energy-conservation purpose.
A kind of general fork truck of handcart-type, its equipment is by pallet fork, crotch, door frame, steel wire rope and pulley, raising liquid
(gas) cylinder pressure etc. is constituted.Described pallet fork is processed into shovel formula shape and constitutes by thicker steel, and it is direct bearing goods
Forked members；Described crotch is the component for fixing pallet fork, and its profile is the structure of a frame shape, and the two ends of crotch are each solid
Surely a steel wire rope is connected, the both sides of crotch are also fixedly connected four pulleys, and crotch is embedded in grooved track by pulley；
Described door frame, is the support for fixing two double acting liquid (gas) cylinders and crotch, and its profile is a well cabinet frame shape
Structure；Described steel wire rope and pulley, pulley is supporting steel-cable movement, used as a tracks of steel wire rope；Steel wire rope
One end be connected with crotch, after the pulley for bypassing raising liquid (gas) cylinder pressure head, the other end is fixed on door frame steel wire rope；Institute
Raising liquid (gas) cylinder pressure stated, it is contemplated that the Long travel of liquid (gas) cylinder pressure is relatively costly, and it is larger to take up room, so from
Two little liquid (pressure) cylinders of stroke carry out efficient combination, reach expansion cylinder body stroke purpose, and raising liquid (gas) cylinder pressure passes through pulley
And steel wire rope, make pallet fork rise or fall movement along grooved door frame.
Description of the drawings
Fig. 1 is a kind of mechanical part component schematic diagram of the general fork truck of handcart-type.
Fig. 2 is the connection figure that a kind of liquid (gas) of the general fork truck of handcart-type presses system.
Specific embodiment
As shown in figure 1,1 is only larger wheels of the general fork truck of handcart-type, it is connected with handle 2, for controlling fork truck
Stroke is moved towards, and also two little wheels are arranged on crotch bottom；3 is driving power supply and liquid (gas) source of fork truck, from generating
, used as the drive energy of fork truck, electromotor selects single-phase generator for machine and liquid (pressure) pump, and power is more than 3KW, liquid (gas) press pump
Power be more than 2KW, output pressure is in below 8Kg.
As shown in figure 1,4 and 7 is steel wire rope, the piston rod of every double acting liquid (gas) cylinder pressure is equipped with a steel wire rope,
One end of steel wire rope is connected (C/D points) with crotch, and steel wire rope after the pulley for bypassing raising liquid (gas) cylinder pressure head, fix by the other end
On door frame (A, B point).
As shown in figure 1, E, R are double-acting liquid (gas) cylinder pressures of two identical cylinder diameters, identical stroke, two double acting gas
(liquid) cylinder is 63mm, stroke 1500mm from cylinder diameter, and will have bar piston end reversely to install by the rodless piston of E, R in opposite directions, this
The effect coupled together by steel wire rope and pulley is planted, stroke of the crotch in grooved guide rail will be made to be cylinder body effective travel
Twice.
As shown in figure 1,5 is the plug of U-steel port, for stopping crotch；6 is U-steel, for embedding the cunning of crotch
Driving wheel；8 is crotch, for fixing pallet fork, double acting liquid (gas) cylinder pressure；9 is pallet fork, is the fork-shaped structure of direct bearing goods
Part.
As shown in Fig. 2 q1, q2 are liquid (gas) pressure control valves of two hand plate types, v1, v2 are two-position five-way valves, and E, R are two
Double acting liquid (gas) cylinder pressure.
As shown in Fig. 2 when q1 is pressed, v1, v2 commutate, the bar piston that has for causing E cylinders stretches out, and R cylinders has bar
Piston is return.The action effect of two liquid (gas) cylinder pressures makes crotch make to lift movement along channel suspending rail.
As shown in Fig. 2 when q2 is pressed, v1, v2 commutate, the bar piston that has for causing E cylinders is return, and R cylinders has bar
Piston stretches out.The action effect of two liquid (gas) cylinder pressures makes crotch make to decline movement along channel suspending rail.
