Abstract
The invention relates to a driving device for a material-conveying trolley of an upward pressing type hydraulic press for building materials. The driving device comprises left and right thrust cylinders, a trolley and a plurality of lifting cylinders, wherein the left and right thrust cylinders are used for moving the material-conveying trolley; the trolley is used for placing stacked plates. The driving device is characterized in that a right plunger oil port is formed on a right plunger arranged at a fixed end of the right thrust cylinder and the trolley; the right plunger oil port is communicated with piston low cavities of the lifting cylinders through oil pipes; a left plunger oil port is formed on a left plunger arranged at a fixed end of the left thrust cylinder and the trolley; the left plunger oil port is communicated with piston upper cavities of the lifting cylinders through oil pipes; and the left thrust cylinder and the upper cavities of the lifting cylinders or the right thrust cylinder and the lower cavities of the lifting cylinders are in serial connection. The driving device provided by the invention has the beneficial effects that all moveable oil pipes or wires can be cancelled, the safe running is ensured, and the cylinder thrusting can be used for saving the installed capacity of the whole device.
Description
Technical field
The invention belongs to hydraulic press, relate in particular to a kind of drive unit of upper pressure type building material hydraulic press feeding trolley.
Background technology
Become the building materials press of the upper pressure type of buttress compacting, because the lower table of hydraulic inverted press is static, framework drives into pressing position and straight sheet pile need to be raised, during compacting, straight sheet pile is fallen on lower table, after compacting finishes, lift slab again, after rolling away from, deliver to unloading station, therefore conventionally on dolly, filling some hoist cylinders lifts straight sheet pile.Be placed in motor on car and drive oil pump, by pipeline to hoist cylinder fuel feeding, or by main Hydraulic Station by flexible pipe to hoist cylinder fuel feeding.Cable or oil cylinder to hoist cylinder fuel feeding will move along with the long distance motion of dolly, and not only structure is not compact, can cause cable leakage and pipeline leakage of oil because of wearing and tearing yet, very dangerous.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, a kind of drive unit of upper pressure type building material hydraulic press feeding trolley is provided, adopt hydraulic oil cylinder driving dolly, the plunger of oil cylinder is connected with the hydraulic fluid port of dolly stiff end and the hoist cylinder of material buttress, can remove removal cable or mobile oil pipe.
The present invention for achieving the above object, be achieved through the following technical solutions, a kind of drive unit of upper pressure type building material hydraulic press feeding trolley, comprise the left and right push action cylinder of moving feeding dolly and dolly and several hoist cylinders of placement straight sheet pile, it is characterized in that: the right plunger of described right push action cylinder and dolly stiff end is provided with right plunger hydraulic fluid port, right plunger hydraulic fluid port is by the piston cavity of resorption UNICOM of oil pipe and hoist cylinder, the left plunger of described left push action cylinder and dolly stiff end is provided with left plunger hydraulic fluid port, left plunger hydraulic fluid port is by the piston upper chamber UNICOM of oil pipe and hoist cylinder, the epicoele of left push action cylinder and several hoist cylinders and right push action cylinder and several hoist cylinder cavity of resorptions are and are connected in series.
Beneficial effect: remove oil pipe and the cable of whole movements, avoid its wearing and tearing to cause cable leakage and pipeline leakage of oil, guarantee equipment safety operation.Adopt oil cylinder pushing feeding trolley simultaneously, can save complete machine installed capacity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, left push action cylinder, 2, left plunger hydraulic fluid port, 3, lower table, 4, hoist cylinder, 5, upper oil pipe, 6, straight sheet pile 7, dolly, 8, lower oil pipe, 9, right plunger hydraulic fluid port 10, right push action cylinder, 11, piston cavity of resorption, 12, piston upper chamber, 13, piston,
The specific embodiment
Below in conjunction with preferred embodiment, to according to the specific embodiment provided by the invention, details are as follows: refer to accompanying drawing, a kind of drive unit of upper pressure type building material hydraulic press feeding trolley, the left and right push action cylinder 1 that comprises moving feeding dolly, 10 and place on the dolly 7 of straight sheet pile 6 and fix several hoist cylinders 4, the right plunger of described right push action cylinder and dolly stiff end is provided with right plunger hydraulic fluid port 9, right plunger hydraulic fluid port is piston cavity of resorption 11 UNICOMs with hoist cylinder by lower oil pipe 8, the left plunger of described left push action cylinder and dolly stiff end is provided with left plunger hydraulic fluid port 2, left plunger hydraulic fluid port is piston 13 epicoele 12 UNICOMs with hoist cylinder by upper oil pipe 5, the epicoele of left push action cylinder and several hoist cylinders and right push action cylinder and several hoist cylinder cavity of resorptions are and are connected in series.
Operation principle, concrete action is as follows:
After having feeded in feeding trolley 7 right sides, after straight sheet pile 6 compactings in left side finish, when right push action cylinder 10 oil-feeds promote right plunger, hydraulic oil also passes through lower oil pipe 8 to hoist cylinder 4 cavity of resorption 11 fuel feeding by right plunger hydraulic fluid port 9, thereby the straight sheet pile 6 at dolly 7 two ends, left and right is held up, after above leave from office 3, dolly 7 is moved to the left.Because the diameter of hoist cylinder 4 and quantity are much larger than right push action cylinder 10.Therefore before dolly 7 is moved to the left, the oil pressure of the cavity of resorption of the hoist cylinder 4 being in series with right push action cylinder 10 has been enough to straight sheet pile 6 picking-ups, and this is the key that the present invention is implemented.Because left and right plunger and dolly 7 are to be rigidly connected, on push action cylinder fixed frame.
After the straight sheet pile in dolly 7 left sides is unsnatched, dolly 7 just moves right under 1 effect of left side push action cylinder, before dolly 7 moves, oil in the oil cylinder 1 of left side enters hoist cylinder piston upper chamber 12 through left plunger hydraulic fluid port 2 makes piston 13 decline like a cork, the lower plane that departs from the straight sheet pile 6 of suppressing, dolly just moves on to right side charging position and waits for next operation cycle.
The above, be only preferred embodiment of the present invention, not structure of the present invention done to any pro forma restriction.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical scheme of the present invention.
