Description
Technical field
The utility model relates to geological drilling technology field, especially a kind of geological drilling rope winch rope length and tension are surveyed
Measure device.
Background technique
Currently, digitlization and informationization are a kind of development trends in geological drilling industry.It is taken in geological drilling rope winch
When heart operation, in order to more accurately understand fisher decentralization depth and judge whether successfully to salvage, a kind of device is needed
Can simultaneously measuring steel wire rope length and tension.
Existing rope winch rope length and the structure of tension measuring device are as shown in Figure 3-4, including rack 10, main shaft 11,
Pressure sensor 12, measurement wheel 13, guide wheel shaft 14, directive wheel 15, wirerope 16 and magnetic speed probe 17.11 liang of main shaft
End is mounted in rack 10；Pressure sensor 12 is mounted on main shaft 11；Measurement wheel 13 is movably arranged on main shaft 11 by bearing
On, it is opened up in outer rim there are four logical magnetic slot 131, four logical magnetic slots 131 are opposite two-by-two；Guide wheel shaft 14 has two, respectively position
In 11 two sides of main shaft, and it is movably arranged in rack 10；There are two directive wheels 15, is movably arranged on directive wheel by bearing respectively
On axis 14,16 one end of wirerope enters in rack 10, successively takes turns 13, another directive wheel 15 around a directive wheel 15, measurement,
The other end is pierced by out of rack 10；Magnetic speed probe 17 is mounted on two walls opposite in rack 10, and face measurement wheel
13 outer rim leads to 131 circular-rotation of magnetic slot, when logical magnetic slot 131 turns to magnetic speed probe 17 when measurement 13 rotation of wheel
When position, logical magnetic is formed, remaining situation is disconnected magnetic.
The working principle of above-mentioned measuring device is as follows: when wirerope is mobile, drives and measures wheel rotation, when measurement wheel rotates,
It is transformed into electric signal by magnetic on-off, eventually by calculating, the revolving speed of measurement wheel is converted into rope length.When wirerope have it is negative
When load, wirerope is generating pressure with measurement wheel joint place, is transferred to pressure sensor by bearing, is converted by angle, most
The tension of rope is obtained eventually.
But this measuring device has the following disadvantages: 1, magnetic speed probe is not sufficiently stable, when revolving speed is very fast,
Speed error is very big；2, for wirerope and measurement wheel contact cornerite very little, when tension is smaller, measurement error is very big.3, it uses
In cornerite very little, revolving speed quickly when, slipping phenomenon frequently occurs, and influences measurement accuracy.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, and provide a kind of geological drilling rope winch rope length and
Tension measuring device.It solves the problems, such as that existing rope winch rope length and tension measuring device measurement error are larger.
The technical solution of the utility model is: geological drilling rope winch rope length and tension measuring device, including bracket,
Force snesor, wirerope, measurement wheel, shaft, bearing block and rotating speed coder；Tension sensor is fixedly mounted on pedestal upper end；
Wirerope is wound around on measurement wheel；Measurement wheel is fixed in shaft by key；Both ends of the shaft is movably arranged on bearing by bearing
On seat；Bearing block is fixedly mounted on bracket；Rotating speed coder is fixedly connected on one end of shaft by limit screw.
The further technical solution of the utility model is: wirerope is 120-170 ° with the contact cornerite a of measurement wheel.
Further technical solution is the utility model: wirerope is 140-160 ° with the contact cornerite a of measurement wheel.
The further technical solution of the utility model is: wirerope is 150 ° with the contact cornerite a of measurement wheel.
The utility model has the advantages that compared with prior art
1, wirerope and measurement wheel contact cornerite are larger, i.e., the contact area between wirerope and measurement wheel is larger, friction
Power is also larger, and wirerope slipping phenomenon is slighter, and error is smaller when this makes measuring steel wire rope rope length, ensure that measurement result
Accuracy.
2, wirerope and measurement wheel contact cornerite are larger, and tension measurement error is smaller, and the tension of wirerope passes through tension and passes
Sensor directly measures, reliable and stable.
The utility model is further described below in conjunction with figure and embodiment.

Specific embodiment
Embodiment 1:
As shown in Figs. 1-2, geological drilling rope winch rope length and tension measuring device, including bracket 1, tension sensor 2,
Wirerope 3, measurement wheel 4, shaft 5, bearing block 6 and rotating speed coder 7.Tension sensor 2 is fixedly mounted on 1 upper end of bracket.Steel
Cord 3 is wound around on measurement wheel 4.Measurement wheel 4 is fixed in shaft 5 by key.5 both ends of shaft are movably arranged on by bearing 51
On bearing block 6.Bearing block 6 is fixedly mounted on bracket 1.Rotating speed coder 7 is fixedly connected on shaft 5 by limit screw 71
One end.
Summary drives 4 rotation of measurement wheel working principle of the utility model is: wirerope 3 is mobile, and measurement wheel 4 drives shaft 5
