Detailed Description
In order to better understand the technical content of the present invention, specific embodiments are described below with reference to the accompanying drawings.
With the development of the uplift pile, the expansion anchor disc plays a key role in the manufacture of the uplift pile, the pore diameter of the bottom expanding section determines how large the expansion anchor disc is placed, if the anchor disc is large and the pore diameter is small, the anchor disc cannot be expanded, and if the pore diameter of the anchor disc is small and the pore diameter is large, the anchor disc cannot play a better uplift role, so that the measurement of the expanding pore diameter before the anchor disc is placed is very necessary.
Diameter-expanding anchor hole measuring device
Referring to fig. 1A, 1B and 2, the diameter-expanded anchor hole measuring device according to the embodiment of the present invention mainly includes a center rod 1, a sliding sleeve 2, a first connecting rod 3, a second connecting rod 4, a first pull rope 5 and a second pull rope 6.
The part which can act according to the change of the aperture comprises a first connecting rod 3, a second connecting rod 4 and a sliding sleeve 2.
The central rod 1, the first connecting rod 3, the second connecting rod 4 and the sliding sleeve 2 are preferably made of stainless steel, and the sliding sleeve has the advantages of long service life and low possibility of damage.
Optionally, the central rod 1 is a cylindrical straight rod with a smooth surface, and the sliding sleeve 2 can slide on the surface of the central rod 1.
Preferably, the sliding sleeve 2 is designed as a sleeve with a through hole, which is sleeved on the outer circumferential surface of the central rod 1. The first end of each first connecting rod 3 is hinged on the sliding sleeve 2. In an alternative embodiment, as shown in fig. 1, protruding ears may be designed on both sides of the sliding sleeve 2 for facilitating the hinged connection with the first connecting rod 3. In an alternative embodiment, the surface of the sliding sleeve 2 may not be designed with ears, but with connecting grooves, and the first connecting rod 3 is hinged in the grooves, such as the aforementioned ears or connecting grooves for hinged connection, which we may refer to as the first hinge, for hinged connection with the first connecting rod 3.
In particular, as illustrated, the two first connecting rods 3 are distributed with central symmetry around the axis of the central rod 1, and the first connecting rods 3 and the second connecting rods 4 are equally long.
In an alternative embodiment, the first connecting rod 3 and the second connecting rod 4 are each a rigid rod, such as a stainless steel round rod or a square rod.
In connection with the illustration, two second connecting rods 4 are distributed around the axis of the central rod 1 in a central symmetry, a first end of the first connecting rod 3 is hinged to the sliding sleeve 2, a second end of the first connecting rod 3 is hinged to a first end of the second connecting rod 4 on the corresponding side, and a second end of each second connecting rod 4 is hinged to the central rod 1, and as shown in connection with fig. 1, the connection position between the second ends of the second connecting rods 4 and the central rod 1 is preferably located at the bottom of the central rod 1 and remains in position.
In connection with the illustrated example, to facilitate the connection, the bottom of the central rod 1 is provided with a second hinge portion 8, for example a connecting member, such as a circular or square, which can be screwed and fixedly fitted to the central rod 1, and the second connecting rod 4 is hinged to this second hinge portion 8, so as to achieve the hinged connection with the central rod 1.
Of course, in other embodiments, the second connecting rod 4 may also be fixed to the central rod 1 in a suitable way.
Therefore, under the action of the gravity of the sliding sleeve 2, the first connecting rod 3 and the second connecting rod 4, the resistance between the sliding sleeve 2 and the central rod 1 is overcome, so that the sliding sleeve 2 has a free downward movement trend, the first connecting rod 3 and the second connecting rod 4 are enabled to be outwards opened, and a hinge point between the two rods has an outward movement trend.
With reference to the figures, since the anchor hole is usually deep, the central rod 1 is connected with the first pull rope 5, the sliding sleeve 2 is connected with the second pull rope 6, and the first pull rope 5 controls the descending depth of the central rod 1, so that when the central rod 1 can be dropped into the expanded-diameter anchor hole by the first pull rope 5, and moves from the contracted hole section to the expanded-hole section, the sliding sleeve 2 and the central rod 1 move relatively, the relative movement amount can be known through the relative sliding of the second pull rope 6 and the first pull rope 5, that is, the displacement amount of the diagonal line in the vertical direction of the diamond structure (i.e., along the central axis direction of the expanded-diameter anchor hole) can be obtained when the contracted hole enters the expanded-hole section.
Optionally, in combination with the figures, the first rope 5 is provided with a first mark point 51, and the second rope 6 is provided with a second mark point 61. The positions of the first mark point 51 and the second mark point 61 are above the orifice, so that when the first mark point 51 and the second mark point 61 are displaced relatively, the operator can observe the displacement, and the offset of the two points can be measured by the measuring tool.
In a further embodiment, as shown in connection with fig. 5, one of the first or second pulling cord 5, 6 is provided with a marking zone and the other pulling cord without a marking zone is provided with a marking point. For example, the first pull rope 5 is provided with a first mark point 51, the second pull rope 6 is provided with a mark area 62, when the first pull rope 5 or the second pull rope 6 slides relatively, the mark area can be observed by an operator, and the offset of the two points can be measured by a length measuring tool.
It should be understood that, in the measurement process performed in the hole of the whole expanded diameter anchor hole measuring device shown in fig. 1A and 1B, when the measuring device is located in the contracted hole section (with a smaller inner diameter), under the gravity of the sliding sleeve 2, the first connecting rod 3 and the second connecting rod 4, the hinge point (i.e. the equivalent connecting point) of the first connecting rod 3 and the second connecting rod 4 has a tendency to abut against and be constrained by the inner wall of the contracted hole section. When the hole expanding section falls, the first connecting rod 3 and the second connecting rod 4 are further expanded, so that the hinged point of the first connecting rod 3 and the second connecting rod is further expanded to abut against the inner wall of the hole expanding section.
In an alternative embodiment, a pull cord connection is provided on both the central rod 1 and the sliding sleeve 2 for securing the first pull cord 5 to the central rod 1 and the second pull cord 6 to the sliding sleeve 2.
In alternative embodiments, the pull-cord connection member comprises a bail or hook. For example, the top of the center pole 1 is provided with a first hanging ring 11, the first pulling rope 5 can be tied on the first hanging ring 11, the top of the sliding sleeve 2 is provided with a second hanging ring 21, and the second pulling rope 6 can be tied on the second hanging ring 21. Therefore, the assembly and the connection are very convenient in construction.
Further, as shown in fig. 1 and 2, a distance L1 between the hinge points at the two ends of the first connecting rod 3 is equal to a distance L2 between the hinge points at the two ends of the second connecting rod 4.
Calculation principle for measuring aperture of hole expanding section
Calculation example 1
In the example shown in fig. 1A and 1B, when the sliding sleeve 2 and the second hinge portion 8 adopt the embodiment shown in fig. 1A and 1B, that is, when the corresponding first connecting rod 3 and second connecting rod 4 are hinged to the sliding sleeve 2, the hinge points on both sides of the sliding sleeve 2 are designed to be centrosymmetric with respect to the sliding sleeve 2, and when the corresponding first connecting rod 3 and second connecting rod 4 are hinged to the second hinge portion 8, the hinge points on both sides of the sliding sleeve are designed to be centrosymmetric with respect to the second hinge portion 8.
Thus, the equivalent diagrams are shown in the states corresponding to fig. 1A and 1B, respectively. Wherein, the measuring device in fig. 1A is located in the shrinkage cavity section, which is equivalent to fig. 2A and 2B; the measurement device in fig. 1B is located in the reaming section, corresponding to fig. 2C and 2D.
Referring to fig. 1A and 2A, when the measuring device is located at the hole shrinkage section, the hinge point of the connecting rods of the first connecting rod 3 and the second connecting rod 4 is abutted to and constrained by the inner wall of the hole shrinkage section. At this time, a central symmetrical hexagon is formed by the two first connecting rods 3, the two second connecting rods 4, the sliding sleeve 2 and the second hinge portion 8, and six vertexes thereof are respectively: two hinge points P of two first connecting rods 3 and sliding sleeve 21And Q1Two second connecting rods 4 and two hinge points X of second hinge part 81And Y1A hinge point R of the first connecting rod 3 and the second connecting rod 4 at one side of the central rod 11And a hinge point Z of the first connecting rod 3 and the second connecting rod 4 at the other side of the central rod 11The hexagonal equivalent shown in fig. 2B.
In this example, the initial state of measurement is the state where the measuring device is located in the shrinkage cavity section, and the midpoint positions of the sliding sleeve 2 are respectively defined as T in conjunction with fig. 2B1The connecting line of the middle point of the sliding sleeve 2 and the middle point of the second hinge part 8 is taken as a symmetry axis and is connected with another symmetry axis R1Z1And vertical, wherein the point O is the center point of the hexagon. Meanwhile, a vertical Q is constructed in FIG. 2B1S1Auxiliary lines to facilitate calculation of T1The initial length of O.
It should be understood that P1Q1Is the distance between the two first connecting rods 3 and the two hinge points of the sliding sleeve 2, can be obtained by pre-measurement, and thus can obtain T1Q1Length of (1), T1Q1＝P1Q1/2。
R1Z1For the pore diameter of the hole shrinkage section, the size can be obtained by detecting the pore diameter on the well, and OZ can be obtained1，OZ1＝R1Z1/2。
In a rectangular OS1Q1T1Middle, OS1＝T1Q1This makes it possible to obtain a square edge S1Z1Length of (i.e. S)1Z1＝OZ1-OS1。
In a right triangle Q1S1Z1For example, the bevel edge Q1Z1Is the length of the first connecting rod 3 and can be obtained by pre-measurement, so that the right-angle side Q can be obtained by the pythagorean theorem1S1Length of (2), i.e. OT is obtained1Length of (1), i.e. OT1＝Q1S1。
Thus, OT in the initial state can be obtained1Which characterizes the position information of the slide 2 in the region of the shrinkage cavity section.
Next, when measuring device fell to the reaming section, because the aperture of reaming section is greater than the aperture of shrinkage cavity section, sliding sleeve 2, head rod 3 and second connecting rod 4 wholly glide down, until the pin joint butt of head rod 3 and second connecting rod 4 to the inner wall of reaming section, received its restraint. At this time, as shown in fig. 2B and fig. 3, the hinge points of the first connecting rod 3 and the second connecting rod 4 at the two sides of the center rod 1 are respectively abutted to the inner wall of the reaming section, and the two first connecting rods 3, the two second connecting rods 4, the sliding sleeve 2 and the second hinge portion 8 are enclosed to form a hexagon with central symmetry, but in the changed hexagon, the center point O 'is changed in position, and as shown in fig. 1A and 1B, relative offset data a, i.e., offset OO', OO ═ a of the center point of the hexagon, is obtained by reading the two pull ropes or measuring the displacement of the pull ropes.
In connection with the illustration, the definition of the vertices of the hexagon in the transformed state corresponds to the definition of the vertices before transformation.
Likewise, in the example shown in FIG. 2D, a vertical Q is constructed2S2Auxiliary lines to facilitate calculation of Z2The final length of O' is calculated to obtain R2Z2I.e. the pore size of the expanded section.
As shown in FIG. 2D, in a right triangle Q2S2Z2Middle, oblique side Q2Z2Is the length of the first connecting rod 3, which can be obtained by pre-measurement.
Right-angle side Q2S2Length and T of2The lengths of O' are the same. Wherein, T2O 'length locks the difference between the length of the hole segment and the offset OO' (i.e., offset data a), and therefore Q2S2＝T2O’＝OT1-OO’。
Thereby, in the right triangle Q2S2Z2In the method, another right-angle side S can be obtained according to the Pythagorean theorem2Z2Length of (d).
Likewise, P2Q2Is the distance between the two first connecting rods 3 and the two hinge points of the sliding sleeve 2, and can be obtained by pre-measurement, so that T can be obtained2Q2Length of (C), T2Q2＝P2Q2/2. And in the rectangle T as shown in FIG. 2D2Q2S2In O' or T2Q2＝S2O’。
Thus, the bore diameter R at the expanded section can be obtained2Z2In conjunction with FIG. 2D, R2Z2＝2(S2Z2+S2O’)。
Thus, in the example shown in fig. 1A and 1B, the relative offset of the measuring device from the keyhole segment to the reaming segment, i.e. the offset data, is measured and read out, and the aperture size of the reaming segment can be calculated through the subsequent calculation process.
Calculation example 2
In another embodiment, in combination with the equivalent schematic diagram shown in fig. 3, when the sliding sleeve 2 and the second hinge portion 8 are designed to be small enough, they can be equivalent to one point, that is, the corresponding sliding sleeve 2 and the second hinge portion 8 in fig. 1A and 1B can be equivalent to one hinge point, so that the two hinge points located on the central rod 1 and the two hinge points of the first connecting rod 3 and the second connecting rod 4 form a diamond structure between the two first connecting rods 3 and the two second connecting rods 4. The diagonals of the diamond shape are always perpendicular, one of which coincides with at least a portion of the central bar 1.
Referring to fig. 1A and fig. 4A and 4B, when the measuring device is located in the hole shrinkage section, the hinge points of the first connecting rod 3 and the second connecting rod 4 at two sides of the central rod 1 respectively abut against the inner wall of the hole shrinkage section as shown in fig. 4A, and the two first connecting rods 3 and the two second connecting rods 4 form a rhombus shape to form a first state, and the four vertexes are: connecting point A of sliding sleeve 2 and central rod 11(the first end of the first connecting rod 3 is hinged to the sliding sleeve 2), and the second end of the second connecting rod 4 is connected with the connecting point B of the central rod 11And a hinge point C of the first connecting rod 3 and the second connecting rod 4 positioned at one side of the central rod 11And a hinge point D of the first connecting rod 3 and the second connecting rod 4 at the other side of the central rod 11。
In the embodiment of the present invention, the state of the measuring device in the shrinkage cavity section is taken as the initial state of the measurement, and the diamond is combined with the state shown in fig. 4BThe first state of the shape is equivalently illustrated, diamond A1C1B1D1Two diagonals A of1B1、C1D1Perpendicular to each other, diagonal A1B1And C1D1Point of intersection O1Is the center of the diamond, and is defined by a diagonal line A1B1And C1D1The triangles formed by division are all right-angled triangles.
In a right triangle A1D1O1For example, its right-angle side is A1O1And D1O1The hypotenuse is A1D1。
Wherein A is1D1Is the length of the first connecting rod 3, a known amount.
Right-angle side D1O1＝C1D12; diagonal line C1D1The pore size of the constriction is obtained by measurement on the upper ground surface.
Thus, in the right triangle A1D1O1Interior, according to the Pythagorean theorem
Can obtain another right-angle side A1O1Which characterizes the position information of the sliding sleeve 2 on the central rod when the measuring device is in the reduced hole section.
Referring to fig. 4C, when the measuring device is located at the reaming section, the sliding sleeve 2, the first connecting rod 3 and the second connecting rod 4 integrally slide down because the aperture of the reaming section is larger than that of the shrinkage section until the hinge point of the first connecting rod 3 and the second connecting rod 4 abuts against the inner wall of the reaming section and is constrained by the hinge point. At this time, as shown in fig. 1B and 4C, the hinge points of the first connecting rod 3 and the second connecting rod 4 at the two sides of the central rod 1 are respectively abutted to the inner wall of the reaming section, and the two first connecting rods 3 and the two second connecting rods 4 are enclosed to form a diamond shape and have a second state.
Referring to FIGS. 4A and 4C, in the reaming section, in the second state, the center point O of the diamond shape is formed2Take place ofMoving upwards, so as to obtain relative offset data a by reading two pull ropes or measuring the displacement of the pull ropes as shown in fig. 4A and 4C and fig. 1A and 1B, that is, the offset O of the center point of the diamond shape in the changing state from the first state to the second state1O2. In conjunction with the illustration, the definition of the vertices of the diamond in the second state is consistent with that in the first state.
Diagonal A, shown in connection with FIG. 4D2B2And C2D2The triangles formed by division are all right-angled triangles.
In a right triangle A2D2O2For example, the right-angle side is A2O2And D2O2The hypotenuse is A2D2。
Wherein A is2D2Is the length of the first connecting rod 3, a known amount.
Right-angle side A2O2＝A2O1Offset O1O2。
Thus, in the right triangle A2D2O2Interior, according to the Pythagorean theorem
To obtain another right-angle side bevel edge D2O2。
With reference to FIG. 4D, at the right triangle ADO2Inner, the shape of the diamond is transformed, the diagonal C2D2Pore diameter representing the pore-enlarging section, D2O2＝C2D2/2, the pore diameter of the expanded section, i.e. 2D, can be obtained2O2Therefore, the hole diameter of the hole expanding section of the expanded anchor hole can be obtained based on the calculation process.

Wherein the pore size of the constricted section can be measured at an orifice on the surface.
When the measuring device enters the hole expanding section from the hole contracting section, the second pull rope 6 moves relative to the first pull rope 5, wherein the relative movement amount can be expressed by the first mark point 51 and the second mark point 61, can be measured and is recorded as relative deviation data a.
As mentioned above, the bore diameter of the reduced bore section of the expanded diameter anchor hole can be measured from the bore diameter of the bore surface, and is denoted as D1.
