[0039] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0040] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0041] In the description of the present application, it should be noted that, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, or the orientation or positional relationship of the product of the present application when it is usually placed, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the present application.

[0042] In addition, if the terms "first", "second", "third" and the like are used herein, they are merely used to distinguish one entity from another, and do not imply a relative importance.

[0043] In addition, if the terms "horizontal", "vertical", "suspended" and the like are used herein, they do not mean that the components must be absolutely horizontal or suspended, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0044] In the description of the present application, it should be noted that, unless otherwise specified and limited, if the terms "provision", "installation", "connection", "connection" and the like are used, they should be understood in a broad sense. For example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0046] It should be understood that in the acoustic non-destructive testing technology, the exposed length of the anchor bolt 100 has a great influence on the acoustic non-destructive testing result, and the exposed length of the anchor bolt 100 is too long, which will cause the detection result to be distorted and cannot meet the design and specification requirements. Among them, the hammer strikes one end of the exposed anchor rod 100, thereby generating a longitudinal stress wave and a reflected wave to the anchor bolt 100. By receiving and analyzing the reflected wave, the grouting density is judged, and then the anchoring quality of the anchor bolt 100 is judged. However, the excitation of the outer end of the anchor bolt 100 will cause strong transverse vibration of the anchor bolt 100, and the strength is several to several tens of times of the longitudinal reflected wave of the received signal, thereby interfering with the signal to be received, resulting in a large deviation of the detection result. Among them, the longer the exposed anchor rod 100, the greater the influence.

[0047] In order to improve the above problems, the present embodiment provides a fixing device for grouting density detection, mainly comprising a shell 200, a lifting piece 300 and a fixing piece. The device is mainly used for fixing the anchor bolt 100 during non-destructive testing, so that the detection result is more accurate.

[0048] As shown in Figure 1 The shell 200 is the installation basis of the device, and the remaining components are installed on the shell 200. The shell 200 adopts a rectangular body, a cylindrical body or a trapezoidal body structure. In the present embodiment, the shell 200 adopts a rectangular body.

[0049] In the embodiment, when the nondestructive testing is performed on the drilled hole 700 after the anchor bolt 100 is anchored and grouting is completed, the shell 200 is arranged on the horizontal ground, and preferably, the upper surface of the shell 200 is parallel to the horizontal ground.

[0050] In the embodiment, as shown in Figures 1-4 The plurality of lifting members 300 are arranged on the upper surface of the shell 200, and the plurality of lifting members 300 are sequentially and spacedly arranged along the extending direction of the side surface of the shell 200. Specifically, the plurality of lifting members 300 can reciprocally displace along the direction perpendicular to the horizontal ground relative to the upper surface of the shell 200, and the plurality of lifting members 300 are sequentially and spacedly arranged along the extending direction of the side surface of the shell 200.

[0051] The plurality of fixing tubes 400 are rotatably connected with the plurality of lifting members 300. Specifically, when the fixing tube 400 fixes the anchor bolt 100, the anchor bolt 100 passes through the plurality of fixing tubes 400, so that the plurality of fixing tubes 400 fix the anchor bolt 100, and the anchor bolt 100 is stable, so that the detection result is more accurate.

[0052] The plurality of fixing tubes 400 can rotate relative to the lifting member 300, so that the orientation of the fixing tube 400 is changed, and the height of the lifting member 300 and the orientation of the fixing tube 400 can be adjusted, so that the plurality of fixing tubes 400 fix the anchor bolt 100 with different inclinations.

[0053] In the embodiment, the lifting member 300 can also be lifted, so that the different number of lifting members 300 and the fixing member on the lifting member 300 fix the anchor bolt 100 with different lengths, so that the device has a wide range of applications.

[0054] In some embodiments, as shown in Figures 1-5 The lifting member 300 includes two lifting columns 310, which are symmetrically arranged relative to the center line of the upper surface of the shell 200 and are perpendicular to the upper surface of the shell 200. Specifically, the shell 200 is provided with a plurality of lifting holes 240, which are perpendicular to the upper surface of the shell 200, and the plurality of lifting columns 310 are arranged in the plurality of lifting holes 240, and the lifting column 310 can reciprocally displace along the direction perpendicular to the upper surface of the shell 200 relative to the lifting hole 240.

[0055] The lifting column 310 can adopt a lifting structure such as a hydraulic cylinder, an electric push rod, and a telescopic rod. In the embodiment, the lifting column 310 adopts an electric push rod, and the motor of the electric push rod is arranged in the lifting hole 240, and the rod body of the electric push rod can be lifted in the lifting hole 240.

[0056] In the embodiment, as shown in Figures 1-6As shown, the fixing pipe 400 comprises a sleeve 410 and two rotating shafts 420, wherein the sleeve 410 is arranged along the center line of the upper surface of the shell 200, and a plurality of lifting columns 310 are arranged on both sides of the sleeve 410, and the plurality of lifting columns 310 are oppositely arranged on both sides of the sleeve 410, specifically, the two lifting columns 310 of the same lifting piece 300 are oppositely arranged on both sides of the sleeve 410 and are perpendicular to the upper surface of the shell 200, and the two rotating shafts 420 are oppositely arranged on both sides of the sleeve 410, preferably, the shafts of the two rotating shafts 420 are located on the same surface as the shaft of the sleeve 410, and the directions of the two rotating shafts are both perpendicular to the axial direction of the lifting column 310, one end of the rotating shaft 420 is fixedly connected with the outer wall of the sleeve 410, and the other end is detachably connected with the lifting column 310, so that the two rotating shafts 420 drive the sleeve 410 to rotate, thereby enabling the sleeve 410 to fix the anchor 100 with different inclinations, wherein the anchor 100 passes through the sleeve 410 when the sleeve 410 fixes the anchor 100.

[0057] In this embodiment, the fixing piece with the sleeve 410 of different sizes can also be replaced by disassembly, so as to fix the anchor 100 with different diameters.

[0058] In this embodiment, as shown in Figures 4-6 The rotating shaft 420 comprises a first fixed end 421, a second fixed end 422 and a rotating piece 423 arranged coaxially, wherein the rotating piece 423 comprises a rotating motor 423a and a rotating shaft 423b, the first fixed end 421, the second fixed end 422, the rotating motor 423a and the rotating shaft 423b are arranged coaxially, the first fixed end 421 is fixedly connected with the outer wall of the sleeve 410, the second fixed end 422 is detachably connected with the lifting column 310, and the two ends of the rotating piece 423 are connected with the first fixed end 421 and the second fixed end 422 respectively.

[0059] In this embodiment, as shown in Figures 1-6 The circumferential side wall of the lifting column 310 is provided with a fixed lug 311, the two lifting columns 310 of the same lifting piece 300 are both provided with the fixed lug 311, the two fixed lugs 311 are arranged close to the top end of the lifting column 310 and are oppositely arranged, the two fixed lugs 311 are respectively directed towards the two second fixed ends 422, and the fixed lug 311 is adapted to the second fixed end 422, the surface of the fixed lug 311 directed towards the sleeve 410 is perpendicular to the horizontal ground, and the surface of the second fixed end 422 directed towards the fixed lug 311 is perpendicular to the horizontal ground, wherein the two fixed lugs 311 are respectively threadedly connected with the two second fixed ends 422, thereby enabling the fixing piece to be detachably connected with the lifting column 310.

[0060] In this embodiment, as shown in Figure 6As shown, the rotating motor 423a is arranged at the first fixed end 421, one end of the rotating shaft 423b is rotatably connected with the rotating motor 423a, and the other end of the rotating shaft 423b is fixedly connected with the center of the second fixed end 422. Specifically, the rotating motor 423a can drive the rotating shaft 423b to rotate, thereby driving the second fixed end 422 to rotate, and further driving the second fixed end 422 to be connected with the fixed protrusion 311.

[0061] When the second fixed end 422 is fixed, the rotating motor 423a rotates relative to the rotating shaft 423b, thereby driving the first fixed end 421 and the sleeve 410 to rotate, so as to adjust the orientation of the sleeve 410.

[0062] In this embodiment, when the anchor 100 arranged horizontally is fixed, the length of the anchor 100 is confirmed, and the number of the lifting members 300 used is confirmed, then the lifting members 300 used are lifted to a certain height, so that the axis of the sleeve 410 is parallel to the axis of the anchor 100, then the device is moved, so that the sleeve 410 is displaced towards the anchor 100, and further so that the anchor 100 passes through the plurality of sleeves 410, and further so that the plurality of sleeves 410 fix the anchor 100.

[0063] When the anchor 100 arranged obliquely is fixed, the fixing members on the lifting members 300 used are first disassembled by disassembling, then the sleeves 410 of the fixing members pass through the anchor 100, so that the fixing members are all arranged on the anchor 100, then the shell 200 is displaced to the lower side of the fixing members, and the lifting columns 310 of the lifting members 300 are lifted to the two sides of the anchor 100, finally, the second fixed end 422 is rotated to be horizontal by the rotating motor 423a, then the second fixed end 422 of the fixing members is sequentially displaced along the anchor 100 to the fixing protrusion 311 corresponding to the lifting column 310 for connection, so that the plurality of sleeves 410 fix the anchor 100 arranged obliquely more simply, and further so that the device can fix the anchor 100 arranged obliquely, and the sleeve 410 is more simply installed on the anchor 100.

[0064] The second fixed end 422 of the rotating shaft 420 of the sleeve 410 is rotated to be horizontal by the rotating motor 423a, so that the second fixed end 422 is connected with the corresponding fixing protrusion 311, and further so that the position of the sleeve 410 is fixed.

[0065] Meanwhile, after the fixing is completed, the sleeve 410 can be further rotated by the rotation of the rotating motor 423a, so as to finely adjust the orientation of the sleeve 410, and further so that the orientation of the sleeve 410 is consistent with that of the anchor 100, thereby stabilizing the fixing of the sleeve 410 on the anchor 100, and achieving better effect.

[0066] In some embodiments, as shown in Figures 1-5 As shown in the same lifting piece 300, the upper surface of the shell 200 between the two lifting columns 310 is provided with a receiving groove 210, and the receiving groove 210 is arranged on the lower side of the fixed pipe 400. The extension direction of the receiving groove 210 is perpendicular to the axial direction of the lifting column 310. A plurality of fixed pipes 400 are respectively accommodated in a plurality of receiving grooves 210. Specifically, when the lifting column 310 is not used, it is accommodated in the lifting hole 240, and when the lifting column 310 is fully accommodated in the lifting hole 240, the fixing piece arranged on the circumferential outer wall of the lifting column 310 and close to the upper end of the lifting column 310 is driven by the lifting column 310 and displaced towards the receiving groove 210, so that the fixing piece is accommodated in the receiving groove 210, thereby reducing the space temporarily used by the device when it is stored, and at the same time, playing a certain protection role.

[0067] It should be understood that the anchor 100 is directly fixed through the sleeve 410, and the sleeve 410 needs to be matched with the anchor 100, so as to avoid the existence of gap between the sleeve 410 and the anchor 100, thereby resulting in low fixing effect. Therefore, the manufacturing precision of the sleeve 410 needs to be high.

[0068] Therefore, in order to improve the above problems, in some embodiments, as shown in Figure 1 and Figure 9 As shown, the outer wall of the sleeve 410 is provided with a telescopic piece 430, and the inner wall of the sleeve 410 is provided with a circular arc plate 800. One end of the telescopic piece 430 penetrates through the outer wall of the sleeve 410 and is connected with the side wall of the circular arc plate 800. The axial direction of the telescopic piece 430 is perpendicular to the axial direction of the sleeve 410, and the axial direction of the circular arc plate 800 is parallel to the axial direction of the sleeve 410. Therefore, the telescopic piece 430 can push the circular arc plate 800 to displace towards the anchor 100, so that the circular arc plate 800 abuts against the anchor 100, thereby fixing the anchor 100. Therefore, one side of the anchor 100 abuts against the inner wall of the sleeve 410, and the other side abuts against the circular arc plate 800, so that the sleeve 410 is more stable in fixing the anchor 100. In addition, since the circular arc plate 800 and the telescopic piece 430 are arranged, the diameter of the anchor 100 can be matched, so that the sleeve 410 and the anchor 100 can have a larger gap, thereby reducing the manufacturing precision of the sleeve 410, and the fixing effect of the device on the anchor 100 is better.

[0069] The circular arc plate 800 is matched with the anchor 100, so that the inner surface of the circular arc plate 800 is in close contact with the outer wall of the anchor 100.

[0070] In some embodiments, the inner wall of the circular arc plate 800 is provided with a shock-absorbing layer 810, so as to further reduce the influence of vibration. The shock-absorbing layer 810 can be made of rubber pad, shock-absorbing cotton and other materials, and can further adapt to the inclination of the anchor 100.

[0071] The telescopic member 430 can be an electric push rod, a telescopic rod, a threaded rod, etc. In this embodiment, the telescopic member 430 is an electric push rod. The driving part of the electric push rod is arranged on the outer wall of the sleeve 410 in the circumferential direction. The push rod of the electric push rod passes through the side wall of the sleeve 410 and is arranged in the sleeve 410.

[0072] In some embodiments, as shown in Figures 1-4 The number of the telescopic members 430 and the arc plates 800 is multiple. The multiple telescopic members 430 are arranged in sequence along the axial direction and the circumferential direction of the outer wall of the sleeve 410. The multiple arc plates 800 are arranged in sequence along the axial direction and the circumferential direction of the inner wall of the sleeve 410. One end of each of the multiple telescopic members 430 is connected to the outer wall of one of the multiple arc plates 800. The number of the telescopic members 430 and the arc plates 800 can be multiple. In this embodiment, the number of the telescopic members 430 and the arc plates 800 is eight.

[0073] In this embodiment, as shown in Figures 1-4 Four telescopic members 430 are arranged on the outer wall of the sleeve 410 in the circumferential direction and close to one end of the sleeve 410. Specifically, the four telescopic members 430 are arranged in sequence along the outer wall of the sleeve 410 in the circumferential direction. One end of each of the four telescopic members 430 is provided with one arc plate 800.

[0074] The other four telescopic members 430 are arranged on the outer wall of the sleeve 410 in the circumferential direction and close to the other end of the sleeve 410. Specifically, the other four telescopic members 430 are arranged in sequence along the outer wall of the sleeve 410 in the circumferential direction. One end of each of the other four telescopic members 430 is provided with one arc plate 800. Thus, the sleeve 410 is provided with the uniformly distributed telescopic members 430 and arc plates 800 at both ends. The anchor 100 can be uniformly supported from different directions, so that the anchor 100 is fixed more stably.

[0075] In this embodiment, when the lifting column 310 is lifted to the preset height, it is determined whether the anchor 100 is horizontal or inclined for installation of the sleeve 410. After the anchor 100 passes through the sleeve 410, the multiple telescopic members 430 are elongated to push the arc plates 800 to move towards the anchor 100. Thus, the arc plates 800 abut and fit the anchor 100, so that the anchor 100 is stably supported and fixed.

[0076] Then, the nondestructive testing instrument 600 is installed on one end of the anchor 100 for testing.

[0077] In this embodiment, the lifting distance of the lifting column 310 can be adjusted according to the inclination of the anchor 100, the length of the anchor 100, etc.

[0078] In some embodiments, as shown in Figures 7-8As shown, the lower side of the shell 200 is provided with a plurality of rollers 220, which are sequentially and spacedly arranged. The rollers 220 are detachably connected with the shell 200, so that the displacement of the shell 200 is relatively simple. Specifically, the lower surface of the shell 200 is provided with a plurality of fixing holes 230, and one end of each roller 220 is provided with a fixing rod 221, which is threadedly connected with a corresponding fixing hole 230.

[0079] In some embodiments, as shown, a control module 500 can also be arranged on one side of the shell 200, and the structures such as the telescopic member 430, the rotating motor 423a, and the lifting column 310 are electrically or wirelessly connected with the control module 500, so that the control module 500 controls the lifting distance and start-stop of the telescopic member 430, the rotation angle and start-stop of the rotating motor 423a, and the telescopic distance and start-stop of the telescopic member 430. Figure 1 As shown, the lower side of the shell 200 is provided with a plurality of rollers 220, which are sequentially and spacedly arranged. The rollers 220 are detachably connected with the shell 200, so that the displacement of the shell 200 is relatively simple. Specifically, the lower surface of the shell 200 is provided with a plurality of fixing holes 230, and one end of each roller 220 is provided with a fixing rod 221, which is threadedly connected with a corresponding fixing hole 230.
