Abstract
The utility model provides a variable-diameter guiding device for drilling holes, which comprises a drill rod and two connecting rods. The variable-diameter guiding device has the technical improvement that a sliding sleeve and a fixed sleeve are further included; the sliding sleeve is sleeved on the drill rod and can slide freely on the drill rod; the fixing sleeve is sleeved on the drill rod and can be fixed on the drill rod through a clamp nut; the two connecting rods are distributed symmetrically to the drill rod; one end of each connecting rod is connected to the sliding sleeve; the other end of the connecting rod is connected to the fixed sleeve; a bearing is connected to the middle of each connecting rod; and a traction device is fixedly connected to the sliding sleeve. Through the adoption of the device, during the drilling of a second hole, the drill rod can be kept in the center of a first hole under the action of the sliding sleeve and the double connecting rods, so that the center of the two holes are superposed.
Description
Technical field
The utility model relates to a kind of drilling equipment of bore operation, concrete relates to a kind of boring reducing guiding device that the center overlaps when making the secondary punching.
Background technology
The application of rig is very extensive, and for example building materials, railway, metallurgy, mine, construction reach Drilling shot hole in the engineerings such as going up the cubic meter of stone.Owing to the influence of geological conditions, ore is inhomogeneous, causes a series of problems such as drilling rod beat and wearing and tearing during boring during rig boring, at present; Though in construction, can generally use guide device,, satisfy the requirement of construction to be that the direction of boring is more accurate; But, in existing boring, bore a hole if desired again, and the center in these two holes should overlap also; Not good at present way, but this is extremely important in the construction, particularly to particularly important in the measurement of geostatic stress.
For example, in the excavation to the coal seam, measuring method commonly used at present does; At first use rig in the punching of the coal seam of the degree of depth to be measured during measurement, then drilling rod is extracted, pressure sensor is put into the measured hole of beating; With clay measured hole is tamped again, need wait until that pressure in the measured hole reaches balance after, could measure geostatic stress accurately through pressure sensor; And the pressure in the hole reach time that balance waits for need usually very long, so this method complex process and time-consuming not only.And when needing to measure the geostatic stress of the different coal degree of depth, need get out measured hole separately respectively.If because utilize the more shallow measured hole of being beaten to continue to measure, the ickings that just need will insert originally earlier or soil and pressure sensor take out from measured hole, on original basis, get out darker measured hole with rig again.
Therefore, during hollow inclusion geodetic stress, need in the punching of originally beating, get an aperture again; And this aperture also must overlap with the center of original punching, and this has just brought certain degree of difficulty to construction, through realizing measuring the position of confirming drilling rod; Can be because various situation, as touching some reason of crag or the like in bit deflection, the decline process, the on the contrary actual hole that comes outbreak out does not overlap with original center; Produce certain error; And this error but influenced the accuracy of measuring greatly, thereby is badly in need of a kind of device, can be so that the hole that the back is beaten overlaps with original center, hole.
The utility model just is being based on this problem and is setting out, and proposes a kind of new device, and this device can be installed on second drilling rod, can be good at overlapping with center and first that guarantees second boring, thereby improves the accuracy of measuring.
The utility model content
The application's technical problem to be solved:
The problem that the utility model can't overlap to the center of mentioning in the background technology; A kind of new device is proposed; This device can be installed on second drilling rod, can be good at overlapping with center and first that guarantees second boring, thereby improves the accuracy of measuring.
The application is that the technical scheme that solves the problems of the technologies described above proposition is:
The utility model proposes a kind of boring reducing guiding device, comprises drilling rod, double link, and its technological improvement is, also comprises sliding sleeve and fixed muffle, sliding sleeve is sleeved on the drilling rod, and can be free to slide at drilling rod 6; The fixed muffle socket is arranged on the drilling rod, and can be fixed on the drilling rod through clamp nut; Described double link is that the center is symmetrically distributed with the drilling rod, and an end of double link is connected on the sliding sleeve, and the other end is connected on the fixed muffle, connects a bearing at the middle part of each double link; Be fixedly connected draw-gear on the sliding sleeve.
In above-mentioned technical scheme, further, described double link is four.
In above-mentioned technical scheme, further, described double link is three.
In above-mentioned technical scheme, further, described draw-gear is a wire rope.
In above-mentioned technical scheme, further, described draw-gear is two, and is arranged symmetrically on the sliding sleeve.
The beneficial effect that the application obtained is:
The utility model makes when boring second hole through adopting so a kind of device because the effect of sliding sleeve and double link, make drilling rod can remain on original hole in the heart, thereby the coincidence of the center in two holes before and after making.
Description of drawings
Fig. 1 is an embodiment of this embodiment;
Fig. 2 is the left view of the utility model.
The specific embodiment
Like Fig. 1, shown in Figure 2, a kind of boring reducing guiding device comprises drilling rod 6, and double link 1 is characterized in that, also comprises sliding sleeve 2 and fixed muffle 3, and sliding sleeve 2 is sleeved on the drilling rod 6, and can be free to slide at drilling rod 6; Fixed muffle 3 sockets are arranged on the drilling rod 6, and can be fixed on the drilling rod 6 through clamp nut 7; Described double link 1 is that the center is symmetrically distributed with drilling rod 6, and an end of double link 1 is connected on the sliding sleeve 2, and the other end is connected on the fixed muffle 3, connects a bearing 4 at the middle part of each double link 1; Be fixedly connected draw-gear 5 on the sliding sleeve 2.
In use; Can earlier this device be enclosed within on the drilling rod 6, and through clamp nut 7 fixed muffle 3 be fixed on this drilling rod 6, this device is along with drilling rod is gone into the well; When drilling rod on earth the time; Can spur draw-gear 5, make symmetrically arranged double link 1 all tightly touch the borehole wall, guarantee that drilling rod is arranged in first hole in the heart.Simultaneously, owing to be provided with bearing 4, make this device and on the borehole wall, to slide with drilling rod decline in the junction of ouble bar link.
Double link in the technique scheme can be four or three, so long as be that a center is symmetrical set and gets final product with drilling rod, the center that so just can guarantee double link is exactly the center of drilling rod; Draw-gear can simply use wire rope, and also can be symmetrical set.
The utility model is not limited to the above-mentioned specific embodiment, and its scope required for protection still is as the criterion with claims of the application, and any simple modifications to this device all belongs to the scope of this application protection.
