Description
Technical field
The present invention relates to a kind of tensioning apparatus, especially a kind of tensioning apparatus for rig advance frame chain, belong to work
Journey mechanical equipment technical field.
Background technology
Because engineering driller field is increasingly intended to miniaturization and multifunction at this stage, and to rig manufacturing cost
Also there is requirement higher with maintenance cost, and because domestic rig kind is numerous, model is uneven, comprehensively gets off, for brill
Machine in itself volumetric constraint and cost consideration, it is necessary to the low advance frame chain of a kind of low cost, easy care, high reliability, modification difficulty
Bar tensioning apparatus.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided a kind of opening for rig advance frame chain
Tight device, ensures that chain keeps tensioning for a long time on the premise of small-sized drill advance frame small volume and control cost, and
It is provided simultaneously with the advantage of easy care, high reliability.
According to the present invention provide technical scheme, a kind of tensioning apparatus for rig advance frame chain, it is characterized in that：Bag
The fixing end and the sliding end installed in axle two ends being fixed on advance frame are included, sprocket wheel is installed by bearing on axle；Described
Axle is respectively arranged at two ends with screwed hole, and regulating bolt is worn in fixing end, and one end of regulating bolt is screwed into the screwed hole on axle
In, the other end of regulating bolt realizes axial locking by nuts and washers.
Further, the fixing end is bolted on advance frame.
Further, the sliding end is arranged on axle two ends by bolt.
Further, the sprocket wheel is fixed on the center of axle by the spacer of both sides.
Further, gland is set in the both sides of the bearing, oil sealing is set in gland, gland outside sets back-up ring, pressure
Sealing ring is set between lid and sprocket wheel.
Tensioning apparatus for rig advance frame chain of the present invention, in small-sized drill advance frame small volume and control
Ensure that chain keeps tensioning for a long time on the premise of cost, while possessing the advantage of easy care, high reliability.
Brief description of the drawings
Fig. 1 is the structural representation of the tensioning apparatus for rig advance frame chain of the present invention.
Fig. 2 is the A-A sectional views of Fig. 1.
Description of reference numerals：Sliding end 1, axle 2, regulating bolt 3, nut 4, packing ring 5, fixing end 6, spacer 7, back-up ring 8, pressure
Lid 9, sprocket wheel 10, spacer ring 11, bearing 12, oil sealing 13, sealing ring 14, advance frame 15.
Specific embodiment
With reference to specific accompanying drawing, the invention will be further described.
As shown in Figure 1 and Figure 2：Tensioning apparatus for rig advance frame chain of the present invention includes being bolted
Fixing end 6 on advance frame 15 and the sliding end 1 at the two ends of axle 2 is arranged on by bolt, chain is installed by bearing 12 on axle 2
Wheel 10, sprocket wheel 10 is accurately fixed to the center of axle 2 by the spacer 7 of both sides.
Screwed hole is respectively arranged at two ends with the axle 2, regulating bolt 3, the one of regulating bolt 3 are worn in fixing end 6
End is screwed into the screwed hole on axle 2, and the other end of regulating bolt 3 realizes axial locking by nut 4 and packing ring 5.It is right when needing
When chain is tensioned, unclamps the spanner of nut 4 and pull regulating bolt 3, it is possible to which band moving axis 2 is moved along regulating bolt 3, is reached
The purpose of chain tension.
Spacer ring 11 is set between the bearing 12, and the outside of bearing 12 sets gland 9, and oil sealing 13, pressure are set in gland 9
The outside of lid 9 sets back-up ring 8, and sealing ring 14 is set between gland 9 and sprocket wheel 10.
The present invention can be reequiped to different types of rig advance frame chain stretching device, variant size, different
The rig advance frame of producer can all use tensioning apparatus of the invention, and the low cost of repacking, versatility is high, is not merely used in one kind
Advance frame.
