Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of length adjustment device of the present utility model.
Detailed description of the invention
The utility model provides a kind of offshore boring island cat road machine centralising device, and structure is simple, easy for installation, reduces cost.Below in conjunction with specific embodiment and Figure of description, the utility model is described in detail.
As shown in Figure 1, the offshore boring island cat road machine centralising device that the utility model provides is arranged on the guide rail of the movable stand of cat road machine, comprise the centralizer group and connecting rod that are symmetricly set on center line of guide rail both sides, each centralizer group comprises former and later two centralizers 5 respectively, each centralizer 5 comprises and affects bar and holding rod, the two ends of connecting rod respectively with two centralizers 5 affect the outer end of bar hinged, connecting rod is parallel to center line of guide rail, one of them centralizer 5 affect the outer end of bar also hinged with driving oil cylinder 2.
As depicted in figs. 1 and 2, connecting rod comprises link body 31 and adjusting rod 32, be provided with length adjustment device 4 between link body 31 and adjusting rod 32, length adjustment device 4 comprises the inner sleeve 41 being provided with screwed hole, the outer sleeve 42 being provided with threaded rod and clamp nut 43, screwed hole and threaded rod coupling.The outer end of link body 31 and adjusting rod 32 affects bar hinged with two respectively.
In the present embodiment, the inner of inner sleeve 41 is provided with dome 411, and the inwall of adjusting rod 32 is provided with the draw-in groove with dome 411 adaptation, and inner sleeve 41 rotates the inner being arranged on adjusting rod 32, and outer sleeve 42 is fixed on the inner of link body 31.As required, also inner sleeve 41 can be fixed on the inner of adjusting rod 32, outer sleeve 42 rotates the inner being arranged on link body 31.Because inner sleeve 41 and adjusting rod 32 are fixed, circumference can only be there is and rotate in inner sleeve 41 relative to link body 31, cannot produce and slide axially, along with the opposite thread between inner sleeve 41 and outer sleeve 42 rotates, therebetween axial distance increases or reduces, and the axial distance therefore between inner sleeve 41 and outer sleeve 42 is exactly the distance of link body 31 and adjusting rod 32.Like this, rotated by opposed helical between inner sleeve 41 and outer sleeve 42, just can distance between regulating connecting rod main body 31 and adjusting rod 32.When being adjusted to suitable distance, by clamp nut 43, the screw rod on outer sleeve 42 and inner sleeve 41 are fixed.
Drive the cylinder barrel of oil cylinder 2 and guide rail to fix, drive the piston rod of oil cylinder 2 and affect bar hinged.In the present embodiment, drive the piston rod of oil cylinder 2, affect bar and link body 31 to be hinged on same jointed shaft.
Each centralizer 5 rotates and is arranged on corresponding centralizer pedestal 6, and centralizer pedestal 6 is fixed on guide rail.
When erection, only need the centralizer pedestal 6 of homonymy be remained on the parallel lines with center line of guide rail, connecting rod install after also should with guideway centreline's line parallel, such connecting rod, two lines affecting bar and two centralizer pedestals 6 should parallelogram or rectangles, install simple, reduce the complexity of assembling.After installation, need by put into drill-rod clamping time, drive the piston rod of oil cylinder 2 protruding, bar is affected to rotate, another centralizer 5 is driven to rotate by connecting rod, the center line of symmetrically arranged holding rod direction guiding rail rotates and then clamping drilling rod, in the process connecting rod always with the center line keeping parallelism of guide rail.
The utility model, only need one group of centralizer driving oil cylinder to drive front side or rear side, the centralizer of opposite side is driven to be synchronized with the movement by connecting rod, thus the drilling rod in the middle of clamping, make drilling rod keep center condition, structure is simple, is easy to install, decrease the number of oil cylinder and required valve block and pipeline, reduce cost.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or close technical scheme with the utility model, all falls within protection domain of the present utility model.
