For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] As Figures 1-6 shown, an auxiliary device for detecting the tensile force of an anchor rod adaptable to complex slope forms proposed by the present utility model includes an anchor rod 2 buried on the surface 1 of the slope and a detection anchor head 3 located at the end of the anchor rod 2. A hook anchor rod 4 is hung outside the detection anchor head 3. A bearing plate 6 through which the hook anchor rod 4 passes is provided on the hook anchor rod 4. A fixing assembly 5 is provided below the bearing plate 6. A jack 7 located outside the hook anchor rod 4 is provided at the upper end of the bearing plate 6. The input end of the jack 7 is communicated with an oil pump 8, and the oil pump 8 is used to drive the jack 7 to jack up the hook anchor rod 4.

[0031] It should be noted that the size and length of the hook anchor rod 4 are determined according to the total height of the fixing assembly 5 and the distance between the detection anchor head 3, and the driving method of the oil pump 8 is a conventional driving method in the prior art, so it will not be described in detail in the text.

[0032] In an alternative embodiment, the fixing assembly 5 includes a support member 9, a spherical cloud platform 12, a needle carving foot 11 and a threaded cross beam 10;

[0033] The support member 9 is arranged at the lower end of the bearing plate 6, the threaded cross beam 10 is arranged on the support member 9, the needle carving foot 11 is arranged below the support member 9, and the spherical pan-tilt 12 is arranged between the support member 9 and the needle carving foot 11, so that the whole fixing assembly 5 can adapt to the complex slope surface 1 and assist in detecting the tension of the anchor head 3.

[0034] In an alternative embodiment, the whole support member 9 is cylindrical. The support member 9 is composed of four threaded steel bars 901, high-strength bolts 903 and two-section telescopic steel pipes 902. The tops of the four threaded steel bars 901 are symmetrically welded to the four corners of the bottom surface of the bearing plate 6, and the bottoms of the threaded steel bars 901 are threadedly connected to the two-section telescopic steel pipes 902 through the high-strength bolts 903, enabling workers to freely add or remove the two-section telescopic steel pipes 902 according to actual usage conditions, and the structure and function of the fixing assembly 5 will not be affected.

[0035] The two-section telescopic steel pipe 902 is composed of a cylindrical hollow threaded steel pipe 904 and a cylindrical solid threaded steel bar 905. The top of the solid threaded steel bar 905 is welded to the bottom of the high-strength bolt 903, enabling the two-section telescopic steel pipe 902 to be telescopic.

[0036] It should be noted that the number of the threaded cross beams 10 is two. The two threaded cross beams 10 are located between the front and rear threaded steel bars 901. The solid threaded steel bar 905 is cylindrical, and the outer wall of the solid threaded steel bar 905 is spliced by half thread and half smooth surface, and its outer wall is rotationally connected to the hollow threaded steel pipe 904 through the thread. The hollow threaded steel pipe 904 is cylindrical, and the inner wall of the hollow threaded steel pipe 904 is spliced by half smooth surface and half thread, and is adapted to the external thread of the solid threaded steel bar 905.

[0037] In this embodiment, when it is necessary to adjust the total length of the support member 9 by adjusting the two-section telescopic steel pipe 902, the total length of the support member 9 is adjusted by rotating and adjusting the hollow threaded steel pipe 904. When it rotates until the smooth surfaces of the solid threaded steel bar 905 and the hollow threaded steel pipe 904 are in contact, when rotating clockwise, the solid threaded steel bar 905 will be screwed up along the thread to shorten the length. After directly sliding down along the smooth surface to the ideal length and then rotating the solid threaded steel bar 905 counterclockwise, the extended section will be screwed up, thereby realizing the adjustment of the telescopic length.

[0038] In an alternative embodiment, a detachable arc-shaped chute block 1201 is rotatably connected to the outer side of the spherical pan-tilt 12. Grooves are formed on both sides of the chute block 1201. The upper surface of the chute block 1201 is circular, and a threaded connection hole is formed at the top of the chute block 1201. A fixing sleeve 1202 is sleeved on the outer side of the chute block 1201. The chute block 1201 is placed in the cylindrical fixing sleeve 1202. Rivets 1203 for connection are provided on both sides of the fixing sleeve 1202. A connection block 1204 located on the chute block 1201 is provided above the fixing sleeve 1202.

[0039] It should be noted that the connection block 1204 is cylindrical, and a through threaded hole is formed in the middle of the connection block 1204. The entire spherical pan-tilt 12 is a regular spherical shape, with a solid sphere and a smooth surface.

[0040] In this embodiment, since a through threaded hole is formed in the middle of the connection block 1204, it can be respectively fastened to the bottom of the threaded steel rod 901 and the two-section telescopic steel pipe 902, ensuring that the fixing assembly 5 can adapt to the complex slope surface 1 at any height in multiple angles. By loosening the rivets 1203 on both sides of the fixing sleeve 1202, the spherical pan-tilt 12 can rotate freely in the fixing sleeve 1202. When the rivets 1203 on both sides are tightened, the angle of the spherical pan-tilt 12 is locked and fixed.

[0041] In an alternative embodiment, the needle carving foot 11 is an isosceles trapezoid columnar body. A thin plate 1101 is welded to the lower end of the needle carving foot 11. A number of circular holes are formed in the middle of the thin plate 1101 and are evenly distributed. A number of thin needles 1102 passing through the circular holes are arranged in the circular holes of the thin plate 1101.

[0042] Among them, the diameter of the circular hole is 1 mm. The lengths of the number of thin needles 1102 are the same, and the length of the thin needle 1102 is the same as the height of the needle carving foot 11. The middle of the thin needle 1102 is a cylindrical shape with a diameter less than 1 mm, and both ends are spherical tops 1103 with a diameter of 2 mm.

[0043] In this embodiment, due to the variability of the shapes of various complex slope surfaces 1, several freely movable thin needles 1102 are arranged below the needle carving foot 11, which can be adjusted in time according to the shape of the slope surface 1 contacted by the fixing assembly 5, ensuring that when assisting the detection anchor head 3 to perform the tensile test, the contact between the bottom of the fixing assembly 5 and the slope surface 1 is expanded from the traditional point contact to surface contact, ensuring the high adaptability of the fixing assembly 5 to various complex slope surface 1 shapes and obtaining accurate tensile test values.

[0044] The working principle of the above embodiments is as follows:

[0045] After connecting the hook anchor rod 4 with the detection anchor head 3 and clamping them in the fixing assembly 5, correct the orientation of the entire fixing assembly 5 according to the tension direction of the detection anchor head 3. That is, fix the needle carving standing leg 11 to the bottom of the support member 9 through the spherical cloud platform 12. After adjusting the needle carving standing leg 11 to be perpendicular to the contacted slope surface 1, lock the angle of the spherical cloud platform 12 through the screw rivet 1203. Press the fine needle 1102 in the needle carving standing leg 11 onto the contacted slope surface 1 until it is completely attached and forms a surface contact. The enlarged contact surface can ensure that the fixing assembly 5 remains stable when working on various complex slope surface 1 forms. Through the two-stage telescopic steel pipe 902 on the high-strength bolt 903, adjust the position of the inner wall thread and the smooth surface of the hollow threaded steel pipe 904, rotate and tighten it on the solid threaded steel rod 905. After adjusting the angles of the needle carving standing legs 11 of the four support members 9 in sequence, adjust the total lengths of the support members 9 in sequence according to the slope heights contacted by the four support members 9 and fix them. Tighten the screw rivet 1203 and the high-strength bolt 903 in sequence to assist in carrying out the subsequent tension detection work of the anchor rod 2 by the jack 7, the detection anchor head 3, and the hook anchor rod 4.
