Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of measurement while drilling, specifically, relate to a metal mine drilling drilling angle measurement while drilling device. BACKGROUND

[0002] Measurement while drilling refers to the drilling machine in drilling continuously detects the information about the borehole or drill bit, rely on tracking and guiding instrument realization. Therefore, tracking and guiding instrument is the necessary measuring equipment of horizontal directional drilling construction, and the measurement while drilling is developed on the basis of measurement while drilling, and a plurality of parameter sensors for formation evaluation are added, such as compensated dual lateral resistivity, natural gamma, azimuthal neutron density, sound wave, compensated neutron density, and the like, and the measurement while drilling instrument needs to be fixed in the drill pipe near the drill bit position through the positioning device in use, and the existing positioning device is matched with the measurement while drilling instrument and the drill pipe one by one, therefore, one kind of positioning device cannot be used for different inner diameters of the drill pipe, and the versatility is relatively low. Secondly, the great vibration generated by the drill bit during work can be transmitted to the drill pipe and the measurement while drilling instrument, which can cause certain influence on the circuit board chip inside the measurement while drilling instrument.

[0003] After retrieval, the patent with publication number CN221590971U discloses a positioning device for measurement while drilling instrument, in which the installation sleeve, the first guide rod, the buffer sleeve, the second guide rod, the sliding sleeve and the abutting assembly are arranged, the measurement while drilling instrument can be fixed in the installation sleeve through the bolts first, then the abutting assembly is driven to open and tightly abut the inner wall of the drill pipe through the sliding sleeve, so that the fixed positioning of the measurement while drilling instrument can be quickly realized. Moreover, the positioning device can adapt to drill pipes with various inner diameters, and has higher versatility, and the buffer assembly arranged in the sliding sleeve can reduce the influence of the drill pipe vibration driven by the drill bit on the measurement while drilling instrument, thereby improving the service life of the measurement while drilling instrument.

[0004] However, when the above-mentioned device is used, since the inner hexagonal knob is not fixedly arranged, although the inner hexagonal knob will not rotate under the action of external force, since the device is used in the field of mine exploration, the device is subjected to the vibration force generated by exploration during use, so that the inner hexagonal knob may still rotate slightly, thereby causing the abutment between the pressing plate and the inner wall of the drill pipe to be not firm, so that the position of the whole device is deviated, which affects the use of the measurement while drilling instrument, and the simple spring and sliding plate structure cannot effectively reduce the influence of the vibration force on the use of the measurement while drilling instrument during work. UTILITY MODEL CONTENT

[0005] The utility model provides a device for measuring the top angle of a borehole while drilling for metal mines. The device has the advantages of facilitating the rapid installation and fixation of the measuring instrument on drill rods of different sizes and effectively reducing the influence of vibration force on the measuring instrument during operation, thereby solving the problem that the measuring instrument is difficult to be effectively fixed and the use effect of the measuring instrument is reduced due to vibration during operation.

A spring damper is fixedly installed on the top of the inner cavity of the cylinder, and a circular plate is fixedly installed on the bottom of the spring damper. Limiting blocks are fixedly installed on the front and rear sides of the circular plate, and a telescopic rod is fixedly installed on the bottom of the circular plate. A measuring device is detachably installed on the bottom of the telescopic rod by bolts.

[0008] Preferably, the polygonal block is connected to the top of the threaded rod through a circular ring and a tension spring, the outer surface shape of the polygonal block matches the shape of the inner cavity of the polygonal hole, and the polygonal hole penetrates into the inner cavity of the outer cylinder, so that when in use, the threaded rod extends from the polygonal hole into the inner cavity of the outer cylinder.

[0009] Preferably, the stretchable length of the tension spring is smaller than the inner cavity depth of the annular cylinder, and the thickness of the polygonal block is smaller than the stretchable length of the tension spring. Thus, when in use, the polygonal block is moved up by the pull ring to move it out of the inner cavity of the polygonal hole. At this time, the rotation of the threaded rod can be controlled by the tension spring and the annular cylinder, thereby changing the position of the outer cylinder and the inner cylinder relative to each other.

[0010] Preferably, one end of the short connecting rod is connected to the outer surface of the outer cylinder through a rotating shaft, the other side of the short connecting rod is connected to the middle of the long connecting rod through a rotating shaft, and the bottom of the long connecting rod is rotatably connected to the left and right sides of the top of the cylinder through a rotating shaft. The adsorption block includes a rubber layer on the outer surface and a magnet in the middle. When in use, the position of the short connecting rod is changed by controlling the position of the outer cylinder, and then the position of the long connecting rod is adjusted, so that the distance between the two relative adsorption blocks changes, thereby meeting the use of drill rods with different inner diameters.

[0011] Preferably, the shape of the outer surface of the slider matches the shape of the inner cavity of the slide groove, and the position of the slider on the inner wall of the outer cylinder matches the position of the slide groove on the outer surface of the inner cylinder, so that when in use, the slider and the slide groove can only move the outer cylinder up and down on the outer surface of the inner cylinder.

[0014] The working principle and beneficial effects of the utility model are as follows:

[0015] The drill hole top angle measurement device for metal mine drilling uses a circular tube structure and a polygonal block structure. When working, the polygonal block is moved out of the polygonal hole by moving the pull ring upward. At this time, the rotation and stretching can drive the threaded rod to rotate, thereby changing the length of the combination of the outer cylinder and the inner cylinder, and then changing the angle between the short connecting rod and the long connecting rod, so that the distance between the left and right adsorption blocks is changed, which meets the use of drill rods with different inner diameters and achieves the effect of facilitating the rapid installation and fixation of the drill rods of different sizes by the drill hole measurement instrument.

[0016] The device for measuring the top angle of a borehole while drilling for metal mines uses a spring damper structure in conjunction with a circular plate structure. The spring damper is used to connect the cylinder and the circular plate, thereby reducing the vibration force transmitted to the circular plate and even the measuring instrument during operation, improving the stability of the measuring instrument during use, and cooperating with a limit groove to prevent the circular plate from moving out of the inner cavity of the cylinder. The combination of multiple structures effectively reduces the impact of vibration force on the measuring instrument during operation. BRIEF DESCRIPTION OF THE DRAWINGS
