Description
Technical field
The utility model is related to a kind of tensioning apparatus, especially a kind of tensioning apparatus for rig advance frame chain, category
In engineering mechanical device 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 higher requirement with maintenance cost, and because domestic rig kind is numerous, model is uneven, integrates, for brill
Machine volumetric constraint itself and cost consideration are, 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 this utility model is to overcome the deficiencies in the prior art to be used for rig advance frame chain there is provided one kind
Tensioning apparatus, small-sized drill advance frame small volume and control cost on the premise of ensure chain keep for a long time tensioning,
While possessing easy care, the advantage of high reliability.
The technical scheme provided according to the utility model, a kind of tensioning apparatus for rig advance frame chain, its feature
It is：Including the fixing end being fixed on advance frame and the sliding end installed in axle two ends, sprocket wheel is installed by bearing on axle；
The two ends of the axle are respectively equipped with screwed hole, and regulating bolt is worn in fixing end, and one end of regulating bolt is screwed into the spiral shell on axle
In pit, 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, set to set in gland, gland in the both sides of the bearing and back-up ring is set on the outside of oil sealing, gland, pressure
Sealing ring is set between lid and sprocket wheel.
Tensioning apparatus described in the utility model for rig advance frame chain, in small-sized drill advance frame small volume and
Ensure that chain keeps tensioning for a long time on the premise of control cost, while possessing easy care, the advantage of high reliability.
Brief description of the drawings
Fig. 1 is the structural representation of the tensioning apparatus described in the utility model for rig advance frame chain.
Fig. 2 is Fig. 1 A-A sectional views.
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.
Embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2：Tensioning apparatus described in the utility model for rig advance frame chain includes passing through bolt
The fixing end 6 that is fixed on advance frame 15 and the sliding end 1 that the two ends of axle 2 are arranged on by bolt, are pacified on axle 2 by bearing 12
Sprocket wheel 10 is filled, sprocket wheel 10 is accurately fixed to the center of axle 2 by the spacer 7 of both sides.
Screwed hole is respectively equipped with the two ends of 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.When needs pair
When chain is tensioned, unclamps nut 4 and regulating bolt 3 is pulled with spanner, 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 and oil sealing 13 is set in gland 9, gland 9, pressure
The outside of lid 9 sets back-up ring 8, and sealing ring 14 is set between gland 9 and sprocket wheel 10.
The utility model can be reequiped to different types of rig advance frame chain stretching device, variant size,
The rig advance frame of different manufacturers can all use tensioning apparatus of the present utility model, and the cost of repacking is low, and versatility is high, not merely makes
For a kind of advance frame.
