Technical field
The utility model relates to a kind of Down-hole rolling rig, and the unit head that especially relates to a kind of Down-hole rolling rig advances hoisting mechanism, and this mechanism is arranged on the jib lubbing mechanism of Down-hole rolling rig.
Background technology
At present, the propelling hoisting mechanism of domestic middle-size and small-size outdoor Down-hole rolling rig unit head, pulley (oil cylinder) propulsive mechanism being formed by hydraulic jack and board-like chain, and the chain wheel driving mechanism that forms of hydraulic motor and roller chain minute, because stability is high, cost is low and lifting force is large etc., plurality of advantages is widely adopted for the former, but also has defect.This mechanism comprises the parts such as unit head, oil cylinder, two cover pulleys and two board-like chains, and pulley and chain are around the home on a vertical forward beam to arranging.During operation, the piston rod of oil cylinder pushes away, pulls pulley yoke to make movable pulley and board-like chain produce revolution, thereby makes unit head carry drilling rod and impactor pumps on forward beam, realizes drilling rod revolution, the impactor object of holing.Defect is as follows: the impact of impactee bore operation, the shake of piston rod very easily damages oil cylinder, and the extent of damage and oil cylinder stroke closely related, therefore, the cost of manufacture of long stroke oil cylinder is very expensive, thereby has restricted the development of the middle-size and small-size outdoor Down-hole rolling rig of domestic low cost.
Summary of the invention
For solving the problems of the technologies described above, the utility model aims to provide a kind of Down-hole rolling rig unit head and advances hoisting mechanism, this mechanism is when increasing oil cylinder stroke, have advantages of with low cost, oil cylinder is not easily damaged, thereby be conducive to promote the fast development of the middle-size and small-size outdoor Down-hole rolling rig of domestic low cost.
For achieving the above object, the utility model has adopted following technical proposals, this Down-hole rolling rig unit head advances hoisting mechanism, comprises forward beam, unit head, oil cylinder and piston rod thereof, movable pulley frame, upper fixed pulley, lower fixed pulley, upper movable pulley, lower movable pulley, the first board-like chain, the first board-like chain fixed end, the second board-like chain, the second board-like chain fixed end; Described forward beam has vertical cavity, and described upper fixed pulley, oil cylinder, upper movable pulley, lower movable pulley and lower fixed pulley are successively set in this cavity from top to bottom; The lower end of described piston rod spins mutually with the upper end of movable pulley frame, upper movable pulley and lower movable pulley are unified by movable pulley frame, it is characterized in that: on the both sides inwall of the forward beam of described piston rod periphery, be respectively provided with a guide strip, suitable with these two guide strips, on the outer wall of the both sides of described movable pulley frame, be respectively provided with a clamp.
During concrete enforcement, the cross sectional shape of described guide strip is spill, and two described clamps lay respectively in the spill mouth of two described guide strips.
During concrete enforcement, the cross sectional shape of described clamp is spill, and the spill mouth of clamp and guide strip arranges in opposite directions.
Beneficial effect: compared with prior art, the utility model is set up after guide strip and clamp, makes the movement locus of movable pulley frame be directed to plate and clamp limits, therefore, during operation, movable pulley frame and connected piston rod there will not be very large shake, thereby can not cause damage to oil cylinder.Based on described improvement, this Down-hole rolling rig unit head advances hoisting mechanism not only can lengthen at low cost oil cylinder stroke, and has advantages of that oil cylinder is not easily damaged, and then is conducive to promote the development of the middle-size and small-size outdoor Down-hole rolling rig of domestic low cost.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The specific embodiment
Referring to Fig. 1, Fig. 2.This Down-hole rolling rig unit head advances hoisting mechanism, comprises forward beam 1, unit head 2, oil cylinder 3 and piston rod 31 thereof, movable pulley frame 4, upper fixed pulley 5, lower fixed pulley 51, upper movable pulley 6, the board-like chain fixed end 81 of the board-like chain 8, second of the board-like chain fixed end 71, second of the board-like chain 7, first of lower movable pulley 61, first.Forward beam 1 forms vertical cavity by two wall section bars, and upper fixed pulley 5, oil cylinder 3, upper movable pulley 6, lower movable pulley 61 and lower fixed pulley 51 are successively set in this cavity from top to bottom.Unit head 2 is fixed on junction plate 21, and junction plate 21 upsides are fixedly connected with first board-like chain 7 one end, and the other end of the first board-like chain 7 is up to be walked around after fixed pulley 5 descendingly again, until walk around movable pulley 6, only goes upward to the first board-like chain fixed end 71.Junction plate 21 downsides are fixedly connected with second board-like chain 8 one end, and the other end of the second board-like chain 8 is descending to be walked around after lower fixed pulley 51 uply again, walks around lower movable pulley 61 and only comes downwards to the second board-like chain fixed end 81.The lower end of the piston rod 31 stretching out downwards from oil cylinder 3 spins mutually with the upper end of movable pulley frame 4, and upper movable pulley 6 and lower movable pulley 61 are unified into the integral body of chain type by movable pulley frame 4.On the inwall of the peripheral forward beam of piston rod 31 both sides, be respectively provided with a guide strip 9, suitable with these two guide strips 9, on the outer wall of the both sides of movable pulley frame 4, be respectively provided with a clamp, that is: left clamp 10, right clamp 101.Guide strip 9 is fixed on forward beam 1 by securing member 91, and left clamp 10 and right clamp 101 are fixed on movable pulley frame 4 through fixture respectively.
During concrete enforcement, the cross sectional shape of guide strip 9 can be spill, two clamps lay respectively in the spill mouth of two guide strips 9, also the cross sectional shape of clamp can be gone out to be also designed to spill simultaneously, the spill mouth of clamp and guide strip 9 is arranged in opposite directions, make movable pulley frame 4 and the movement locus of the piston rod 31 that spins with it is directed to bar 9 and limits.Left clamp 10, right clamp 101 and two guide strips 9 all adopt concave structure, and arrange in opposite directions, facts have proved the restriction effect of movable pulley frame 4 and piston rod 31 better, there will not be very large shake in operation.For guaranteeing that piston rod 31 freely stretches, the length of guide strip 9 should be suitable with the range of oil cylinder.
Above-described embodiment is only for explaining the present utility model thinking, and any simple deformation structure that is subject to its inspiration and makes, all should include protection domain of the present utility model in.
