the expansion unit 5 includes a first connection ring 51, a second connection ring 54, an auxiliary arm 52, and a contact plate 53;
the inner ring of the first connecting ring 51 is provided with threads which are matched with the thread segments 32 in a threaded manner;
the second connecting ring 54 is fixedly connected to the middle part of the contact joint 4;
the two ends of the contact plate 53 are respectively hinged with the first connecting ring 51 and the second connecting ring 54 through auxiliary arms 52;
The middle part of the movable joint 3 is sleeved with a cross 6, and the end part of the cross 6 is connected with a telescopic sleeve 61 in a sliding manner;
The inner side of the contact plate 53 is fixedly connected with a telescopic rod 55, and the telescopic rod 55 is in sliding fit with a telescopic sleeve 61.
In the prior art, the jack is adopted to expand to drive the ring buckle to be attached to the inner wall of the hole, one surface of the ring buckle, which corresponds to the inner wall of the hole, cannot be guaranteed to be flush with the inner wall of the hole, so that the measurement of the verticality of the detection device is converted into the measurement of the verticality of the hole, larger errors are necessarily caused, the quality of the hole formed by the compaction pile cannot be guaranteed, and errors occur in the judgment of the bearing capacity of the hole formed by the compaction pile in the later stage.

Specifically, when the detection device is used, the detection device is placed in a hole, the cone head at the bottom of the contact joint 4 is kept close to the center of the bottom surface of the hole, then the driving joint 1 is rotated by manpower, the movable joint 3 and the contact joint 4 are driven to rotate relatively (the contact joint 4 is kept in a static state under the pressure action of the movable joint 3 and the driving joint 1), when the movable joint 3 rotates, the first connecting ring 51 at the outer part of the detection device is in threaded fit with the threaded section 32 so as to generate axial displacement, and when the first connecting ring 51 is axially displaced, the upper auxiliary arm 52 can be driven to deflect, so that the contact plate 53 is outwards expanded by being matched with the lower auxiliary arm 52 to deflect at the second connecting ring 54 until the contact plate 53 abuts against the inner wall of the hole;
Wherein, because of the restriction of the cross 6 and the telescopic sleeve 61, the contact plate 53 is always parallel to the axis of the detection device in the process of passive outward displacement, when the contact plate 53 abuts against the inner wall of the hole, the error of the detection device is reduced, and the measured verticality of the detection device can be converted into the verticality of the hole; in addition, when the detecting device is placed in the hole, since the second connecting ring 54 is fixedly connected to the contact joint 4, and both ends of the contact plate 53 are respectively connected to the first connecting ring 51 and the second connecting ring 54 via the auxiliary arms 52, when the movable joint 3 rotates, the threaded section 32 can be in a threaded fit relationship with the first connecting ring 51, thereby completing the expansion of the contact plate 53.

As shown in fig. 4 to 5 and 8, the device further comprises a correction unit 7; the correcting unit 7 is used for correcting the superposition of the axis of the movable joint 3 and the hole forming axis of the compaction pile; the driving joint 1 is of a hollow structure, and a lifting rod 8 is connected inside the driving joint 1 in a sliding manner; the middle part of the lifting rod 8 is fixedly connected with a connecting buckle 82; a plurality of circular waist grooves 11 are formed in the outer wall of the driving joint 1 in an annular array, and connecting buckles 82 penetrate through the circular waist grooves 11 and are connected with the correction unit 7.
As shown in fig. 12, even if the contact plates 53 are parallel to the axis of the detection device during displacement, when the opposite two contact plates 53 contact the inner wall of the hole with the upper end and the lower end respectively, the two contact plates can also abut against the inner wall of the hole, but the axis of the detection device cannot coincide with the axis of the hole, and a small error exists, so that the verticality measured by the detection device cannot be directly converted into the verticality of the hole;
Based on the above, as an embodiment of the present invention, the axis of the detecting device can be corrected to coincide with the axis of the hole forming by using the correcting unit 7 provided on the driving joint 1 in cooperation with the expanding unit 5 provided on the movable joint 3 to expand synchronously or sequentially, so that the measured verticality of the detecting device can be directly converted into the verticality of the hole forming;
specifically when using, after expansion unit 5 accomplishes the expansion, pull up pull rod 8 through the manpower for connector link 82 on the pull rod 8 produces the displacement, after connector link 82 produces the displacement, can make correction unit 7 expand and expand, the expansion of cooperation expansion unit 5, thereby will be in the drive festival 1 axis adjustment of correction unit 7 center to coincide with the pore-forming axis, then can directly convert the straightness that hangs down that this inclinometer measured into the straightness that hangs down of pore-forming.

When the lifting rod 8 is specifically used, the clamping groove 81 at the bottom of the lifting rod 8 is displaced towards the movable joint 3 by manual force until the top surface of the clamping block 37 is extruded, so that the clamping block 37 is displaced outwards (the bottom of the lifting rod 8 is also provided with an inclined surface as shown in fig. 7), the clamping block 37 is contracted and then reset under the action of elastic potential energy of the second spring 35, and is clamped in the clamping groove 81, so that the lifting rod 8 is fixed in the driving joint 1 and the movable joint 3, and transportation before and after use is facilitated;
In addition, when the detection device is in use, the straight rod 34 is pulled outwards by manpower, the clamping block 37 can be separated from the clamping groove 81 at the bottom of the lifting rod 8, and the lifting rod 8 can be separated from the limiting state at the moment, so that the detection device can be lifted upwards and the correction unit 7 is driven to be unfolded so as to adjust the axis of the detection device.

As an embodiment of the present invention, the first spring 21 disposed between the lifting rod 8 and the threaded section 32 generates elastic potential energy when the lower clamping groove 81 of the lifting rod 8 is clamped in the movable joint 3, and simultaneously, after the first spring 21 is released, the lifting rod 8 can be supported, so that the lifting rod 8 is prevented from being completely contracted in the driving joint 1 and the movable joint 3.
As shown in fig. 6 to 7, the top of the hollow inserted link 41 is provided with an inclined plane, and the hollow inserted link 41 is in plug-in fit with the bottom of the lifting link 8; the inner diameter of the hollow inserted link 41 is Yu Di larger than the outer diameter of the lower part of the pull rod 8.
In order to facilitate the use of the lifting rod 8, as an embodiment of the invention, when the detection device is placed in the hole, due to the pressure of the movable joint 3 and the driving joint 1, the hollow inserted rod 41 at the top of the contact joint 4 relatively moves upwards, namely upwards moves in the inner cavity 33 of the movable joint 3, and extrudes the clamping block 37 to move outwards, so that the clamping block 37 is separated from the clamping groove 81 on the lifting rod 8, and at the moment, the lifting rod 8 can be directly ejected by utilizing the elastic potential energy of the first spring 21, and then the lifting rod 8 is pulled upwards by being matched with manpower in a suitable way, so as to complete the expansion of the correction unit 7, and realize the adjustment of the axis of the detection device;
the inner diameter of the hollow inserting rod 41 is larger than the outer diameter of the bottom of the lifting rod 8, so that the lifting rod 8 can be inserted into the hollow inserting rod 41 to avoid clamping.
Working principle: in the prior art, the jack is adopted to expand to drive the ring buckle to be attached to the inner wall of the hole, one surface of the ring buckle, which corresponds to the inner wall of the hole, cannot be guaranteed to be flush with the inner wall of the hole, so that the measurement of the verticality of the detection device is converted into the measurement of the verticality of the hole, larger errors are necessarily caused, the quality of the hole formed by the compaction pile cannot be guaranteed, and errors occur in the judgment of the bearing capacity of the hole formed by the compaction pile in the later stage.
Based on the above, when the detection device provided by the invention is used, the cross 6 and the telescopic sleeve 61 are in sliding fit with the telescopic rod 55 on the inner side of the contact plate 53, when the first connecting ring 51 is displaced to drive the auxiliary arm 52 to deflect, the angle of the contact plate 53 can be limited, and the contact plate 53 is ensured to be always parallel to the axis of the movable joint 3, namely the axis of the detection device in the displacement process along with the deflection of the auxiliary arm 52, so that after the expansion unit 5 is fully expanded, the axis of the detection device can be adjusted to coincide with the axis of the hole, and then the verticality of the detection device is measured by adopting the inclinometer on the top of the driving joint 1, so that the verticality of the hole can be directly converted into the error caused by the fact that the axis of the contact plate 53 is not parallel to the axis of the detection device is eliminated;
Specifically, when the detection device is used, the detection device is placed in a hole, the conical head at the bottom of the contact joint 4 is kept close to the center of the bottom surface of the hole, then the driving joint 1 is rotated by manpower, the movable joint 3 and the contact joint 4 are driven to rotate relatively by the rotation of the driving joint 1 (the contact joint 4 is kept in a static state under the pressure of the movable joint 3 and the driving joint 1), when the movable joint 3 rotates, the first connecting ring 51 outside the movable joint 3 is in threaded fit with the threaded section 32, so that axial displacement is generated, and after the first connecting ring 51 is axially displaced, the auxiliary arm 52 can be driven to deflect, so that the contact plate 53 is outwards expanded by matching with the second connecting ring 54 until the contact plate 53 abuts against the inner wall of the hole;
Wherein, because of the restriction of the cross 6 and the telescopic sleeve 61, the contact plate 53 can only move radially in the passive outward displacement process and is parallel to the axis of the detection device at any time, when the contact plate 53 abuts against the inner wall of the hole, the error of the detection device is reduced, and the measured verticality of the detection device can be converted into the verticality of the hole; in addition, when the detecting device is placed in the hole, since the second connecting ring 54 is fixedly connected to the contact joint 4, and both ends of the contact plate 53 are respectively connected to the first connecting ring 51 and the second connecting ring 54 via the auxiliary arms 52, when the movable joint 3 rotates, the threaded section 32 can be in a threaded fit relationship with the first connecting ring 51, thereby completing the expansion of the contact plate 53.
Even if the contact plates 53 are parallel to the axis of the detection device in the displacement process, when the upper ends and the lower ends of the two opposite contact plates 53 are respectively contacted with the inner wall of the hole, the two opposite contact plates can also be abutted against the inner wall of the hole, but the axis of the detection device cannot coincide with the axis of the hole, and small errors exist, so that the verticality measured by the detection device cannot be directly converted into the verticality of the hole;
Based on the above, as an embodiment of the present invention, the axis of the detecting device can be corrected to coincide with the axis of the hole forming by using the correcting unit 7 provided on the driving joint 1 in cooperation with the expanding unit 5 provided on the movable joint 3 to expand synchronously or sequentially, so that the measured verticality of the detecting device can be directly converted into the verticality of the hole forming;
Specifically when in use, after the expansion unit 5 finishes expansion, the lifting pull rod 8 is pulled up by manpower, the connecting buckle 82 on the lifting pull rod 8 slides upwards in the waist round groove 11, the driving arm 72 is hinged with the connecting buckle 82, so that after the connecting buckle 82 moves upwards, the driving arm 72 can be driven to deflect, the expansion arm 71 is further expanded outwards through the driving arm 72, the contact plate 53 is driven to expand outwards by matching with the auxiliary arm 52, and therefore the axes of the detection device, namely the axes of the driving joint 1, the movable joint 3, the extension joint 2 and the contact joint 4, are regulated to coincide with the pore-forming axes, at the moment, the measured verticality by the inclinometer can be directly converted into the pore-forming verticality, the error is further reduced, and the measured verticality is closer to the actual verticality of the pore-forming.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
