Description
Technical field
The utility model relates to a kind of hydraulic spreader not bouncing back.
Background technology
Hydraulic spreader as a kind of machine tool because of its volume little, easy to operate, obtained at present generally applying widely, when but hand-hydraulic expander uses at present, handle is only arranged on a side, while needing others to assist, there is no the leeway of setting about, and can not make expander keep certain opening width, inconvenient rescue work, can not guarantee operator's safety, also because current hydraulic spreader does not arrange shoe, when requiring assistance personnel's rescue, could not catch tightly owing to not having shoe to cause expanding and cause slipping out, cause serious consequence.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple to operate, rational in infrastructure, has the anti-skidding effect not bouncing back.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of hydraulic spreader not bouncing back, include base, include handle and expansion arm, on described handle, be provided with oil-feed bolt, hydraulic cylinder, two-way hydraulic valve and piston, described oil-feed bolt is arranged on a side of hydraulic cylinder, by oil-feed bolt, oil is done to inlet hydraulic cylinder, make hydraulic cylinder, described oil-feed bolt and hydraulic cylinder fixed-link, described two-way hydraulic valve is arranged on the end of hydraulic cylinder, by two-way hydraulic valve, control the duty of hydraulic cylinder, by two-way hydraulic valve, block the motion of hydraulic pressure, make piston hydraulic pressure is fixed on to the position of pushing expansion arm open, play the fixing effect not bouncing back, described piston is arranged in hydraulic cylinder, described piston and hydraulic cylinder active link, pushing by piston is opened expansion arm, described expansion arm is provided with two, in described expansion arm, be provided with anti-slop serrations, the object both sides that the power of catching by anti-slop serrations can make expansion arm latch firmly will expand, can tightly not cause expanding not open owing to catching, play anti-skidding effect, described each expansion arm is flexibly connected with hydraulic cylinder by bearing pin, the piston coming by hydraulic cylinder promotes expansion arm, make expansion arm running.
As preferably, described expansion arm is set to aluminium alloy expansion arm, is difficult for getting rusty.
As preferably, described piston is made by steel alloy, and compressive resistance is strong.
The beneficial effects of the utility model are: owing to being provided with two-way hydraulic valve, can control the duty of hydraulic cylinder, by two-way hydraulic valve, block the motion of hydraulic cylinder hydraulic pressure, make piston that hydraulic pressure is fixed on and opens the position of pushing expansion arm open before two-way hydraulic valve, reach the fixing effect not bouncing back, owing to being provided with anti-slop serrations, the object both sides that the power of catching by anti-slop serrations can make expansion arm latch firmly will expand, can tightly not cause expanding not open owing to catching, play anti-skidding effect.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that a kind of hydraulic spreader expansion arm not bouncing back of the utility model closes.
Fig. 2 is the schematic diagram that a kind of hydraulic spreader expansion arm not bouncing back of the utility model is opened.
The specific embodiment
Consult shown in Fig. 1-2, a kind of hydraulic spreader not bouncing back, include handle 1 and expansion arm 2, on described handle 1, be provided with oil-feed bolt 3, hydraulic cylinder 4, two-way hydraulic valve 5 and piston 6, described oil-feed bolt 3 is arranged on a side of hydraulic cylinder 4, oil-feed bolt 3 can oil-feed, make hydraulic cylinder 4 runnings, described oil-feed bolt 3 and hydraulic cylinder 4 fixed-link, described two-way hydraulic valve 5 is arranged on the end of hydraulic cylinder 4, by block the motion of hydraulic cylinder 4 by two-way hydraulic valve 5, by two-way hydraulic valve 5, block the motion of hydraulic cylinder 4 hydraulic pressure, make piston 6 that hydraulic pressure is fixed on and opens the position of pushing expansion arm 2 open before two-way hydraulic valve 5, described piston 6 is arranged in hydraulic cylinder 4, piston 6 promotes hydraulic pressure, described piston 6 and hydraulic cylinder 4 active links, described expansion arm 2 is provided with two, in described expansion arm 2, be provided with anti-slop serrations 7, during use, anti-slop serrations 7 latches are lived the object both sides increase skid resistance of expansion, described each expansion arm 2 is flexibly connected with hydraulic cylinder 4 by bearing pin 8, the hydraulic pressure of hydraulic cylinder 4 promotes the expansion of expansion arm 2.
Described expansion arm 2 is set to aluminium alloy expansion arm, is difficult for getting rusty.
Described piston 6 is made by steel alloy, and compressive resistance is strong.
During use, oil is fastened to 3 by oil-feed and enter in hydraulic cylinder 4, the object both sides that anti-slop serrations 7 latches will expanded, by piston 6, make hydraulic open expansion arm 2, while opening up into suitable position, by regulating two-way hydraulic valve 5 to regulate hydraulic pressure holding position not bounce back.
The beneficial effects of the utility model are: owing to being provided with two-way hydraulic valve, can control the duty of hydraulic cylinder, by two-way hydraulic valve, block the motion of hydraulic cylinder hydraulic pressure, make piston that hydraulic pressure is fixed on and opens the position of pushing expansion arm open before two-way hydraulic valve, reach the fixing effect not bouncing back, owing to being provided with anti-slop serrations, the object both sides that the power of catching by anti-slop serrations can make expansion arm latch firmly will expand, can tightly not cause expanding not open owing to catching, play anti-skidding effect.
The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement all should be encompassed in the new protection domain of this practicality and be as the criterion.
