Detailed description of the invention
Below in conjunction with accompanying drawing, describe the present invention in detail.
Refer to Fig. 1-4, of the present invention can the jack of fast lifting, comprise upper frame 1, footstock, height adjustment assembly and positioning component, upper frame is arranged on footstock, height adjustment assembly and positioning component are fixed on footstock, and height adjustment assembly and positioning component are arranged on the side of upper frame.
Upper frame 1 comprises a cylinder 12 and is arranged on the arc shape support portion 11 of cylinder one end, and a side of cylinder is provided with ratchet row 121.Ratchet row 121 is provided with several downward-sloping teeth 1211.
Height adjustment assembly comprises jacking block 35, jacking block pull back spring 34, contiguous block 33, shifting bar 32 and mobile lever pin 31, contiguous block 33 is fixed on shifting bar 32 by mobile lever pin 31, contiguous block 33 comprises one can first groove of first end of accommodating jacking block 35, the first end of jacking block 35 comprises one can the second groove 351 of accommodating jacking block pull back spring, and jacking block 35 is fixed in the first groove of contiguous block 33 by jacking block pull back spring 34.Second end 352 of jacking block 35 is in cutter head shape, and its blade is relative with the cylinder 12 of upper frame, and its point of a knife upwards can prop up the gap of ratchet row 121.
Positioning component comprises upper frame fixture block 42, unlocks lever pin 41 and trip lever 43, and upper frame fixture block 42 is fixed on trip lever 43 by unlocking lever pin 41.Upper frame fixture block 42 is in cutter head shape, and its blade is relative with the cylinder 12 of upper frame, and its point of a knife upwards props up the gap of ratchet row 121, is fixed on trip lever 43 bottom it by unlocking lever pin 41.Positioning component also comprises a safe lock dog 44 and upper frame lock 45, can arrange the through hole that can hold snap ring 46 and pass in the end of safe lock dog 44 and upper frame lock 45.
Footstock comprises cover block 21 and leg 22, and cover block 21 is arranged on leg 22.Cover block 21 hollow is provided with trepanning 211, and one end of upper frame 1 is arranged in trepanning 211.On cover block 21, arrange 121 adjacent two sides with ratchet and respectively arrange and can hold the first through hole 212 that shifting bar 32 passes and the second through hole 213 that trip lever 43 passes can be held.On cover block 21, arrange 121 adjacent two sides with ratchet and be also provided with the third through-hole 214 that can hold safe lock dog 44 and pass, arrange 121 adjacent sides with ratchet and be also provided with and can hold upper frame and lock 45 fourth holes passed 215.On cover block 21, arrange 121 relative sides with ratchet and arranges and can hold fifth hole 216 that mobile lever pin 31 passes and the 6th through hole 217 unlocking lever pin 41 and pass can be held.On cylinder 12, a side relative with fourth hole 215 arrange one extend along the axis direction of cylinder 12, the 3rd groove 122 one end that upper frame locks 45 inserted can be held, upper frame lock is inserted fourth hole and can prevent upper frame from departing from footstock.
Can arrange the through hole that can hold snap ring 46 and pass at a side of cover block 21, the snap ring through this through hole couples together by rope with the snap ring locking the through hole of the end of 45 through safe lock dog 44 and upper frame, can prevent safe lock dog 44 and upper frame lock 45 from losing.
Refer to Fig. 2 again, during use, the point of a knife of upper frame fixture block 42 upwards props up the gap of ratchet row 121, and now, arc shape support portion 11 can support weight, in order to strengthen safety, safe lock dog 44 can be passed third through-hole 214, to prop up the gap of ratchet row 121.When upper frame will be made to decline fast, rotate trip lever, drive upper frame fixture block 42 to skid off the slot gap of ratchet row 121, upper frame can decline by fast free.When needs promote upper frame, the point of a knife of upper frame fixture block 42 upwards props up the gap of ratchet row 121, upwards rotate shifting bar, thus drive contiguous block to rotate, by lifting upper frame one lattice after jacking block compression jacking block pull back spring 34, meanwhile, the point of a knife of upper frame fixture block upwards props up ratchet and arranges next tooth, thus is fixed by upper frame.Rotate shifting bar again, jacking block ejects by jacking block pull back spring 34 under elastic force effect, then when upwards rotating shifting bar, by lifting upper frame one lattice, like this, fast upper frame one lattice one lattice can up can be risen to the height of needs again.Even if under load condition, also upper frame can be promoted in this way.
The present invention can make upper frame rise fast by height adjustment assembly and positioning component and drop to suitable height, and safety performance is good; Further, the present invention also can at hoisting depth under load condition, practical.
Be only several specific embodiments of the application above, but the application is not limited thereto, the changes that any person skilled in the art can think of, all should drops in the protection domain of the application.
