Description
Technical field
The utility model is related to a kind of blasthole tricone rock bit device.
Background technology
Blasthole tricone rock bit is mainly used in stripping and the ore extraction of all kinds of opencuts, the rotary drill of different size model
Head can in different rock stratum the various diameters of Drilling hole, blown out for blasting charge.Blasthole tricone rock bit assembling is divided into
Packing and the big process of general assembly two.Two big main parts of packing are gear wheel and bit leg, are fitted together, and form the overall gear wheel tooth of single-piece
The palm is and dispenses.General assembly is exactly to have dispensed assembling components by three by external force to unify, finally by welding after always installing
It is fixed.
General assembly is one critical process, if angles and positions have deviation during general assembly, there is larger error with former design drawing
When, it is small, adjustment of doing over again is carried out, drilling life of bit is then had a strong impact on greatly.Drill quality was so not only taken a lot of work but also had influenceed.During general assembly
Inevitable three classes error：Misalignment position error, high and low position error and angle heeling error.General assembly before is all by rule of thumb
Assembling, rigging error scope is larger, without controllability.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of simple structure, process and assemble conveniently, and
Improve the blasthole tricone rock bit device of the service life of rock bit.
To achieve these goals, the utility model is achieved through the following technical solutions：
A kind of blasthole tricone rock bit device, the device include three rock bit, the rock bit include gear wheel and
Bit leg, it is characterised in that described device also includes triangle polyester fibre block and triangle polyester fibre piece, the bit leg is provided with locating slot and determines
Position block groove, the locating piece groove is located at locating slot top, and three faces of the triangle polyester fibre piece are respectively provided at determining for three bit legs
In the groove of position, the triangle polyester fibre block is located on three locating piece grooves of bit leg, and by being welded and fixed.
From above-mentioned technical proposal as can be seen that the utility model is by using triangle polyester fibre block and triangle polyester fibre piece, and
Locating slot and locating piece groove are provided with bit leg so that directly accurately can be assembled together three rock bit, triangle polyester fibre
Block can reduce misalignment position error, and triangle polyester fibre block piece can reduce high and low position error and angle heeling error, reduce total
Dress rework rate, directly improves drill quality, the raising drilling life of bit of indirect.

In this, as to restriction of the present utility model.
It should be noted that in following embodiments, using the schematic diagram of Fig. 1~4 to by a kind of ore deposit of the utility model
Detailed statement has been carried out with tricone bit device.When implementation method of the present utility model is described in detail, for convenience of description, show
Intention is not drawn according to general ratio and has carried out partial enlargement and omission treatment, therefore, should avoid in this, as to this practicality
New restriction.
As shown in figures 1-4, the utility model provides a kind of blasthole tricone rock bit device, and the device includes three teeth
Wheel drill bit, rock bit includes gear wheel 1 and bit leg 2, and device also includes triangle polyester fibre block 6 and triangle polyester fibre piece 5, set on bit leg 2
There are locating slot 3 and locating piece groove 4, locating piece groove 4 is located at the top of locating slot 3, and three faces of triangle polyester fibre piece 5 are respectively provided at three
In the locating slot 3 of bit leg 2, triangle polyester fibre block 6 is located on three locating piece grooves 4 of bit leg 2, and by being welded and fixed.
In sum, the utility model is by using triangle polyester fibre block 6 and triangle polyester fibre piece 5, and is provided with bit leg 2
Locating slot 3 and locating piece groove 4 so that directly accurately can be assembled together three rock bit, triangle polyester fibre block 6 can be reduced
Misalignment position error, triangle polyester fibre block piece 5 can reduce high and low position error and angle heeling error, reduce general assembly rework rate,
Directly improve drill quality, the raising drilling life of bit of indirect.
Although it is understood that the utility model is disclosed as above with preferred embodiment, but above-described embodiment is not
