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 is as a kind of mobile handling machinery, because it has good manoevreability and commonality, therefore be suitable for that cargo type is many, the goods amount large and must be rapidly department's use of collecting and distributing and turnover, become port and pier, railway station and the indispensable instruments of department such as goods yard, warehouse, logistics company.
Summary of the invention
The fork truck of a kind of handcart-type of the present invention, its characteristics are: 1, fork truck adopts steel rope tractive shelf; 2, adopt two little double acting liquid (gas) cylinder pressure effectively to connect, make it to have the expanded functionality of cylinder body stroke.Stroke such as two little cylinder bodies respectively is 1000MM, after two liquid (gas) cylinder pressure is connected, then can realize total kilometrage 2000MM.Thereby be implemented under the equal stroke state, the saving of very large limit the cost of investment of fork truck, reach energy-conservation purpose.
A kind of fork truck of handcart-type, its equipment is comprised of pallet fork, crotch, door frame, steel rope and pulley, the liquid that hoists (gas) cylinder pressure etc.Described pallet fork is propped up by thicker steel and is processed into shovel formula shape and consists of, and it is the forked members of direct bearing goods; Described crotch is the fixing member of pallet fork, and its profile is the structure of a frame shape, steel rope of each captive joint of the two ends of crotch, and the both sides of crotch are four pulleys of captive joint also, and by pulley crotch are embedded in the channel suspending rail; Described door frame is the support that is used for fixing two double acting liquid (gas) cylinders and crotch, and its profile is the structure of a well cabinet frame shape; Described steel rope and pulley, pulley are that supporting steel-cable moves, as a tracks of steel rope; One end of steel rope links to each other with crotch, and steel rope is after walking around the liquid that hoists (gas) cylinder pressure head and getting pulley, and the other end is fixed on the door frame; The described liquid that hoists (gas) cylinder pressure, the long stroke cost of considering liquid (gas) cylinder pressure is higher, and it is larger to occupy the space, so select two little liquid (gas) cylinder pressures of stroke effectively to make up, reach and enlarge cylinder body stroke purpose, hoist liquid (gas) cylinder pressure by pulley and steel rope, make pallet fork rise or descend mobile along the flute profile door frame.
Description of drawings
Fig. 1 is a kind of mechanics member scheme drawing of fork truck of handcart-type.
Fig. 2 is a kind of connection diagram of liquid (gas) pressing system of fork truck of handcart-type.
The specific embodiment
As shown in Figure 1, the 1st, a solely large wheel of the fork truck of handcart-type links to each other with handle, is used for controlling the direction of travel of fork truck, also has two little wheels to be installed in the crotch bottom; The 3rd, the driving power of fork truck and liquid (gas) source, select electrical generator and liquid (gas) press pump as the drive energy of fork truck, electrical generator is selected single phase generator, and power is that the power of the above liquid of 3KW (gas) press pump is that output pressure is below 8KG more than the 2KW.
As shown in Figure 1,4 and 7 is steel ropes, the piston rod of every double acting liquid (gas) cylinder pressure all disposes a steel rope, one end of steel rope link to each other with crotch (C, D point), steel rope is after walking around the liquid that hoists (gas) cylinder pressure head and getting pulley, and the other end is fixed on (A, B point) on the door frame.
As shown in Figure 1, E, R are double-acting liquid (gas) cylinder pressures of two identical cylinder diameters, identical stroke, with the rodless piston end of E, R in opposite directions, and will have the bar piston end oppositely to install, this effect that couples together by steel rope and pulley is the twice of cylinder body effective travel with the stroke that makes crotch in channled rail.
As shown in Figure 1, the 5th, the plug of channel-section steel port is used for stopping crotch; The 6th, channel-section steel is used for embedding the slip wheel of crotch; The 8th, crotch is used for fixing pallet fork, double acting liquid (gas) cylinder pressure; The 9th, pallet fork is the forked members of direct bearing goods.
As shown in Figure 2, Q1, Q2 are liquid (gas) pressure control valves of two hand plate types, and V1, V2 are two-position five-way valves, and E, R are two double acting liquid (gas) cylinder pressures.
As shown in Figure 2, when Q1 was pressed, V1, V2 all commutated, and cause the bar piston that has of E cylinder to stretch out, and the bar piston that has of R cylinder were return.The action effect of two liquid (gas) cylinder pressure makes crotch make lifting mobile along channel suspending rail.
As shown in Figure 2, when Q2 was pressed, V1, V2 all commutated, and cause the bar piston that has of E cylinder to be return, and the bar piston that has of R cylinder stretched out.The action effect of two liquid (gas) cylinder pressure makes crotch do to descend mobile along behaviour's shape track.
