Abstract
The utility model discloses a kind of novel tube pulling unit, aim to provide a kind of structure simple, stable, stressed good tube pulling unit, its technical scheme is mainly articulated and connected with shift fork and stand, stand is fixed a parallel-crank mechanism, opposing side, the face that shift fork contacts with steel pipe is provided with groove, described parallel-crank mechanism is mounted in groove, adopt Driven by Hydraulic Cylinder device to drive parallelogram, thus drive the motion of shift fork, adopt this mechanism, ensure that shift fork working stability in tube pulling process, hydraulic cylinder force is good.
Description
Technical field
The utility model relates to a kind of tube pulling unit, and more particularly, it is simple that it relates to a kind of structure, and stability is high, the stressed good novel tube pulling unit of actuating device.
Background technology
Steel pipe tube pulling is requisite operation in steel pipe transport process, generally fork is all adopted to carry out tube pulling at present, waste time and energy, and easily cause steel tube surface temperature Jiangdu too much, even secondary circuit heating, technological requirement can not be met, China Patent No. CN 203006459 U proposes a kind of tube pulling unit for these problems, mainly by shift fork afterbody with to be fixedly connected on stand be that chain is hinged, immobile liquid cylinder pressure on stand, by Hydraulic Cylinder shift fork upward movement, shift fork afterbody is subject to the pulling force of chain, shift fork tilts, its major advantage is that structure is simple, cost is low, and steel pipe tube pulling can be realized very well, but its stability is not high, shift fork easily rocks, hydraulic cylinder force is very large, reduce the work life of hydraulic actuating cylinder.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of structure is simple, stability is high, the stressed good novel tube pulling unit of actuating device.
For achieving the above object, the utility model provides following technical scheme: a kind of novel tube pulling unit, comprise stand, shift fork and hydraulic actuating cylinder, described stand is provided with groove, slot opening direction is towards shift fork direction, stand is provided with parallel-crank mechanism, described parallel-crank mechanism comprises two horizontal edges and two vertical edges, described horizontal edge and vertical edge are articulated and connected, the opposing face in contact steel pipe of described shift fork is provided with groove, groove opening direction is towards stand direction, a horizontal edge of described parallel-crank mechanism is mounted in described groove, another horizontal edge is fixedly mounted in stand groove, described stand is provided with hydraulic actuating cylinder, hydraulic actuating cylinder comprises cylinder body and piston, described hydraulic cylinder body and piston are articulated and connected with stand and parallel-crank mechanism one vertical edge respectively, described shift fork and stand are articulated and connected.
By adopting technique scheme, stand is fixed with parallel-crank mechanism, and parallel-crank mechanism is embedded in the groove of shift fork, Driven by Hydraulic Cylinder parallel-crank mechanism controls the motion of shift fork, structure is simple, stability is high, hydraulic cylinder body and piston respectively with stand and parallel-crank mechanism hinged, avoid and when hydraulic actuating cylinder is fixedly connected with, easily to occur the phenomenons such as dead angle is stuck, parallelogram to be fixed in the groove of stand but not bench surface, more ensure that stability when parallelogram works, a vertical edge of Driven by Hydraulic Cylinder parallel-crank mechanism controls the motion of shift fork, directly control compared with shift fork rises with hydraulic actuating cylinder, hydraulic cylinder force is little, long service life.
The utility model is set to further: described hydraulic actuating cylinder is positioned at the region surrounded by two horizontal edges and two vertical edges.
By adopting technique scheme, hydraulic actuating cylinder is arranged on inside parallel-crank mechanism, saves while space hold, and contact with shift fork, stand etc. when can avoid hydraulic cylinder works and disturb, safe reliability is high.
The utility model is set to further: described shift fork is provided with curved portions and described arc part in the hinged relative one end of shift fork and stand.
By adopting technique scheme, one end that shift fork is relative with one end hinged with stand is designed to arc, and when steel pipe market is to tube pulling unit, ensure that shift fork is stirred steel pipe and not easily dropped, steel pipe by arris wearing and tearing etc., can not play certain protective effect to steel pipe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In accompanying drawing, 1. shift fork; 2. hinge; 3. articulated section; 4. parallel-crank mechanism; 41.Parallelogram horizontal edge; 42. parallelogram vertical edges; 5. hydraulic actuating cylinder; 51. pistons; 52. cylinder bodies; 6. stand.
Detailed description of the invention
A kind of novel tube pulling unit, comprise shift fork 1, stand 6, hydraulic actuating cylinder 5 and parallel-crank mechanism 4, described stand 6 is provided with groove, slot opening direction is towards shift fork direction, groove internal fixtion has a horizontal edge 41 of parallel-crank mechanism 4, shift fork 1 is provided with groove, groove opening direction is towards stand 6 direction, the horizontal edge 41 of parallel-crank mechanism 4 is embedded in groove, the tail end of shift fork 1 is provided with through hole, stand 6 is provided with articulated section, articulated section is provided with through hole, hinge 2 is provided with in through hole, shift fork 1 and stand 6 are articulated and connected by hinge 2, stand 6 is fixedly connected with hydraulic cylinder base, hydraulic cylinder body 52 and hydraulic cylinder base are articulated and connected, the vertical edge 42 of hydraulic cylinder piston 51 and parallel-crank mechanism 4 is articulated and connected, four limits that hydraulic actuating cylinder 5 is arranged on parallel-crank mechanism 4 are inner.
When shift fork 1 does not need tube pulling, hydraulic cylinder piston 51 is in the state of stretching out, and now parallel-crank mechanism 4 is in confined state, and shift fork 1 is the level of state, when shift fork 1 works tube pulling, hydraulic cylinder piston 51 is regained, and now parallel-crank mechanism 4 is softened, shift fork 1 upward movement, because shift fork 1 afterbody and stand 6 are articulated and connected, stand 6 fixedly mounts on the ground, and therefore, shift fork 1 tilts to carry out tube pulling.
The work of shift fork 1 adopts hydraulic actuating cylinder 5 to drive parallel-crank mechanism 4 to drive, and arranges like this, improves the working stability of shift fork 1; Hydraulic actuating cylinder 5 is arranged in four limits of parallel-crank mechanism 4, and what avoid hydraulic actuating cylinder 5 and stand 6, shift fork 1 etc. contacts interference, safe and reliable, simultaneously, a side close with shift fork 1 arch section of hydraulic actuating cylinder 5 major control parallel-crank mechanism 4, make hydraulic actuating cylinder 5 stressed little, reliability is high; Parallel-crank mechanism 4 to be fixedly mounted in the groove of stand 6 but not on table top, to ensure that parallel-crank mechanism 4 working stability, can not rock, improve the working stability of overall tube pulling unit.
