Description
Technical field
The utility model is related to a kind of kelly bar measurement slide calliper rule.
Background technology
《SY/T6509-2000 kelly bars》Drilling rod sleeve gauge, the amount are used to the measurement of kelly bar drive part in standard
General weight is advised in more than 20kg, measurement needs two inspectors and overhead traveling crane to coordinate, and measurement process is cumbersome, and gauge is easy with drilling rod
Rub, damage kelly bar drive part surface.Need to configure the drilling rod sleeve of corresponding size for different chi lattice kelly bars
Gauge.
The content of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art to provide one kind to substitute plurality of specifications side
Drilling rod sleeve gauge, reduction measure slide calliper rule to the kelly bar of kelly bar surface damage.
What the technical solution of the utility model was realized in：A kind of kelly bar measures slide calliper rule, the slide calliper rule include main scale,
Vernier scale frame, position limiting ruler frame, main scale handle, spring, fastening screw and heat-insulating shield, the trip is installed on the main scale blade
Scale frame, both are relative to slide, and the vernier scale inframe is equipped with the graduated vernier scale of mark, the main scale and the vernier scale
Frame left side is equipped with measuring jaw, and the position limiting ruler frame is made up of two parts chi frame in the vernier scale frame both sides, two parts chi
Connected with steel plate between frame, the synchronous slide on the main scale, the position limiting ruler frame of the measuring jaw side of the vernier scale frame
Upper to install the fastening screw, the position limiting ruler frame portion point of the vernier scale outer frame side installs institute between the vernier scale frame
Spring, the main scale handle and the main scale side of being connected thereto are stated, the heat-insulating shield is set on the main scale handle.
The size scale of the main scale of described kelly bar measurement slide calliper rule is 0-200mm, and slide calliper rule resolving power is 0.01mm.
Described kelly bar measures the measuring jaw measuring surface length 160mm of slide calliper rule, flatness≤0.003mm, surface roughness
Within Ra0.2 μm, the two measuring jaw depth of parallelisms≤0.01mm.
The good effect that the technical solution of the utility model is produced is as follows：The slide calliper rule are existed using the vernier scale frame with measuring jaw
Relative motion with main scale, by the position limiting ruler frame with trip bolt on blade, by the blade of slide calliper rule and the amount of chi frame two
Parallel spacing is measured between pawl and is locked in the dimensional measurement ranges that the drive part of kelly bar specifies, complete the driving to kelly bar
Portion size is measured, and the slide calliper rule are light to be easy to carry about with one, it is only necessary to reviewer's execute-in-place, and the work for reducing inspector is strong
Degree, improves checkability, covers《SY/T6509-2000 kelly bars》Kelly bar drive part square size measurement model in standard
Enclose, square sleeve gage can be substituted, measurement is accurate, and drilling rod surface nondestructive is hindered.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model kelly bar measures slide calliper rule.
It is labeled as in figure：1st, main scale；2nd, vernier scale frame；3rd, position limiting ruler frame；4th, main scale handle；5th, spring；6th, fasten
Screw；7 heat-insulating shields；8 kelly bars；9 vernier scales.
Specific embodiment
A kind of kelly bar measures slide calliper rule, as shown in figure 1, the slide calliper rule include main scale 1, vernier scale frame 2, position limiting ruler frame 3, master
Scale handle 4, spring 5, fastening screw 6 and heat-insulating shield 7, install the vernier scale frame on the main scale blade, both are relative
Slide, the vernier scale inframe is equipped with the graduated vernier scale 9 of mark, the main scale and the vernier scale frame left side amount of being equipped with
Pawl, the position limiting ruler frame is made up of two parts chi frame in the vernier scale frame both sides, is connected with steel plate between two parts chi frame
Connect, the synchronous slide on the main scale, the fastening is installed on the position limiting ruler frame of the measuring jaw side of the vernier scale frame
Screw, the position limiting ruler frame portion point of the vernier scale outer frame side installs the spring, the master between the vernier scale frame
Scale handle and the main scale side of being connected thereto, the heat-insulating shield is set on the main scale handle.
The size scale of the main scale of described kelly bar measurement slide calliper rule is 0-200mm, and slide calliper rule resolving power is 0.01mm.
Described kelly bar measures the measuring jaw measuring surface length 160mm of slide calliper rule, flatness≤0.003mm, surface roughness
Within Ra0.2 μm, the two measuring jaw depth of parallelisms≤0.01mm.
Specific kelly bar drive part square size measuring process：
1st, basis《SY/T6509-2000 kelly bars》Kelly bar drive part opposite side Wide measuring range in standard, for example：
3 " kelly bar drive part, a width of 78.6mm of opposite side, it is allowed to deviation（0~ +0.13）mm.
2nd, moving cursor chi frame first, due to the effect of spring, position limiting ruler frame is with movement, main scale and vernier scale frame two
Parallel spacing is measured between measuring jaw for 78.6mm, while the fastening screw on position limiting ruler frame is locked.
3rd, reviewer is held on main scale handle heat-insulating shield, and the drive part opposite side of card amount kelly bar 8 is removed with the slide calliper rule
Size wide, point level, the measurement of vertical both direction, measures in kelly bar drive part every 0.5m.If slide calliper rule can the side of sticking into
Drilling rod drive part, illustrates that drive part regulation lower deviation under gauge judges that kelly bar is unqualified herein herein；Drill with ferrule
Bar drive part square size size such as exists（0~ +0.13）Within mm, under the action of the spring, slide calliper rule can smoothly card amount, judgement side
Drilling rod is qualified herein；When kelly bar drive part square size size exceeds tolerance, slide calliper rule card does not enter drive part and then judges
Kelly bar is unqualified herein.
The other forms of parallel distance measurement, such as capacitance-grid type digital show rulers between main scale and the measuring jaw of vernier scale frame two
Or pointer circular scale, also in the utility model protection domain.
