Description

Technical Field

[0001] The invention relates to the technical field of anchor rod pull-out test, and in particular to a slope displacement measuring device based on anchor rod pull-out test. Background Art

[0002] In slope engineering, anchor support is a common stabilization measure. The traditional anchor pull-out test evaluates the pull-out bearing capacity by measuring the displacement of the exposed part of the anchor, but this method is easily disturbed by factors such as the concave surface of the slope, resulting in poor measurement accuracy. In order to solve this problem, technicians have developed a slope displacement measurement device based on the anchor pull-out test. The device pulls the anchor through a through-hole jack and uses a displacement sensor to measure the displacement of the base plate to accurately reflect the elongation of the anchor. However, in practical applications, the device still faces some challenges. Especially in the case of complex or unstable slope conditions, such as uneven, loose or weathered slope surfaces, and possible deformation caused by the pull-out force, it may make it difficult to stably install and measure the device. In addition, environmental factors such as rainfall and wind may also have an adverse effect on the measurement accuracy. Therefore, how to achieve stable installation and accurate measurement of the device under complex slope conditions has become a key issue that needs to be solved at present.

[0003] For example, the Chinese utility model patent CN219475211U discloses a "displacement measuring device for a slope anchor pull-out test". Its specification discloses that the existing displacement measuring instruments usually need to be used in conjunction with a jack during use. The jack usually needs to be nested and fixed on the anchor. The overall mass of the jack is heavy. Since the anchor of the slope is usually in an inclined state, the pulling force provided by the jack is an oblique upward force. Therefore, the weight of the jack and the displacement measuring instrument will affect the effect of the anchor pulling force, resulting in a certain error in the measurement value of the displacement measuring instrument. The above patents can prove the defects of the existing technology.

[0004] Therefore, we made improvements and proposed a slope displacement measurement device based on anchor pull-out test. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0044] As described in the background art, especially when the slope conditions are complex or unstable, such as uneven, loose or weathered slope surface, and possible deformation due to pull-out force, it may make it difficult to stably install and measure the device.

[0048] The present invention provides a slope displacement measuring device based on an anchor pull-out test, which can be rotated in left and right directions and is arranged at the end of a sleeve 4 or attached to the sleeve 4, so as to protect the measuring part 3 and the internal connecting part 2, and at the same time make up the distance between the extended end of the anchor and the ground, so as to prevent the problem of measurement deviation caused by uneven ground.

[0049] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0050] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0051] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0052] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 , a slope displacement measuring device based on anchor pull-out test, the adaptation device 5 also includes two L-shaped limit rods 503 fixedly connected to the sleeve 4, the L-shaped limit rods 503 each pass through the arc groove on the limit plate 502 on the side and reach the side of the limit plate 502 away from the L-shaped limit rod 503, the L-shaped limit rod 503 passes through the end of the limit plate 502 and is fixedly connected to the limit roller 504.

[0053] When the rotating clamp 501 rotates relative to the sleeve 4, the L-shaped limiting rod 503 passing through the limiting plate 502 forces the rotating clamp 501 to rotate within a certain angle, thereby controlling the swing amplitude between the sleeve 4 and the end anchor rod and adjusting whether the measuring part 3 and the anchor rod are level.

[0054] The adapting device 5 further comprises a hollow plate 505 fixedly connected between the two rotating clamping plates 501 . The hollow portion of the hollow plate 505 is a circular groove, and a rotating bearing 506 is fixedly connected to the circular groove of the hollow plate 505 .

[0055] Please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9, a slope displacement measuring device based on anchor pull-out test, the adaptation device 5 also includes a micro drive motor 507 fixedly connected to the outer wall of one side of a single rotating clamp plate 501, the micro drive motor 507 is fixedly connected to a transmission gear 508 through a coupling and a rotating shaft, the transmission gear 508 is rotatably connected to the hollow plate 505 through a bearing on the side away from the micro drive motor 507, and a driven gear 509 is fixedly connected to the rotating bearing 506, and the transmission gear 508 is meshed with the driven gear 509.

[0056] The micro drive motor 507 provides power to rotate the transmission gear 508 , so that the transmission gear 508 cooperates with the driven gear 509 to rotate the rotating bearing 506 , thereby allowing the fixed block 510 to perform a circular motion around the rotating bearing 506 .

[0057] The adaptation device 5 also includes two fixed blocks 510 fixedly connected to both sides of the rotating bearing 506, the fixed blocks 510 are provided with a sloped circular groove 511, the highest surface of the sloped circular groove 511 is provided with a slot 512 for locating the position of the arc-shaped limit plate 6, the fixed block 510 is provided with a rectangular groove 513, the fixed block 510 is provided with a circular groove 514, and the fixed block 510 and the sloped circular groove 511 are circular grooves that gradually deepen from the direction of the circular groove 514 to the direction of the rectangular groove 513.

[0058] The sloped circular groove 511 prevents the circular plate 516 from being on the same horizontal plane under the restriction of the ball 518 and the L-shaped rod 517, resulting in the arc-shaped limit plate 6 not only playing a protective role when it is on the sleeve 4 and away from the sleeve 4, but also being able to adapt to anchor rods of different sizes through the action of the telescopic part 515 when pre-clamping the anchor rod.

[0059] The adaptation device 5 also includes a telescopic part 515 fixedly connected to the annular groove 514, and the outer ring of the telescopic part 515 is provided with a spring. The two ends of the spring of the telescopic part 515 are respectively fixedly connected to the circular plate 516 and the annular groove 514, and the top of the telescopic part 515 is fixedly connected with a circular plate 516 for connecting the arc-shaped limit plate 6. The circular plate 516 and the arc-shaped limit plate 6 are hinged, and the arc-shaped limit plate 6 can only be lifted upward by a slight distance and displaced in the horizontal direction by a certain distance. An L-shaped rod 517 is fixedly connected to one side of the circular plate 516, and a ball 518 is fixedly connected to the end of the L-shaped rod 517, and the ball 518 is in contact with the sloped circular groove 511.

[0060] When the L-shaped rod 517 is at different positions in the circular ring in the sloped circular groove 511, the circular plate 516 can be lifted to a certain height through its slope position. At the same time, when the ball 518 on the L-shaped rod 517 enters the slot 512, it will limit the rotation of the arc-shaped limiting plate 6.

[0061] Example 2 further optimizes the slope displacement measurement device based on the anchor pull-out test provided in Example 1. Specifically, Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, the interlocking device 7 includes an interlocking groove 701 provided on both sides of the sleeve 4, the interlocking groove 701 is a U-shaped interlocking groove with inconsistent heights on both sides in cross section, an arc surface groove 702 is provided on the arc-shaped limiting plate 6, an interlocking cylinder 703 is fixedly connected to the inner wall of one end of the arc surface groove 702, a damper 704 is fixedly connected in the interlocking cylinder 703, a spring is arranged on the damper 704, and a connecting plate 705 is fixedly connected to the side of the damper 704 away from the interlocking cylinder 703.

[0062] The fixed shaft 706 is in the fitting groove 701, which enables the arc-shaped limiting plate 6 and the sleeve 4 to form a fitting relationship, and enables the arc-shaped limiting plate 6 to completely cover the slot 12 so that the internal components can be protected.

[0063] The fitting device 7 further comprises a fixed shaft 706 fixedly connected between the two connecting plates 705 , and a rotating outer ring 707 is rotatably connected to the fixed shaft 706 for fitting and fixing with the fitting groove 701 .

[0064] Further, such as Fig.12 and Fig.13 As shown, the interlocking device 7 also includes a plurality of grooves 708 on the arc-shaped limit plate 6, and a locking nut 709 is threadedly connected in the groove 708. A trapezoidal groove 710 is provided on the arc-shaped limit plate 6. The locking nut 709 passes through the arc-shaped limit plate 6 and is connected to a trapezoidal rod 711 by bolts, and a cross groove 712 is provided on the trapezoidal rod 711.

[0065] The trapezoidal rod 711 can rotate during the adjustment of the lock nut 709, so that the trapezoidal rod 711 can rotate in the trapezoidal groove 710. It should be added that the trapezoidal rod 711 is chamfered near the bottom of the trapezoidal groove 710 to facilitate the rotation of the trapezoidal rod 711 in the trapezoidal groove 710.

[0066] The number of grooves 708 and trapezoidal rods 711 on the arc limiting plate 6 is inconsistent, and the number of trapezoidal rods 711 on the upper arc limiting plate 6 is greater than the number of the lower arc limiting plate 6, and the trapezoidal rods 711 on the lower arc limiting plate 6 are located at the midline of the two upper trapezoidal rods 711, that is, when the upper arc limiting plate 6 overlaps with the lower arc limiting plate 6, the lower trapezoidal rods 711 are located in the middle of the upper trapezoidal rods 711 and are staggered.

[0067] The non-contact and rotatable trapezoidal rods 711 are staggered in the upper and lower arc-shaped limit plates 6, so that the trapezoidal rods 711 in the inclined state can serve as a similar structure to the thread groove, so that the structure can cooperate with the threaded protrusion structure on the anchor rod and move under the anchor rod surface while rotating itself.

[0068] The use process of the slope displacement measuring device based on the anchor pull-out test provided by the present invention is as follows:

[0069] 1. The initial state of the device is as follows Figure 1 and Figure 2 In the state shown, the arc-shaped limit plate 6 cannot rotate on the horizontal plane because the fixed shaft 706 is in the fitting groove 701. Figure 4 and Figure 8 In the initial state, the ball 518 at the bottom of the L-shaped rod 517 is in the slot 512 at the highest point of the sloped circular groove 511. The arc-shaped limit plate 6 in the double-guaranteed state cannot suddenly rotate when the double insurance is closed, causing danger. Fig.12 In the state shown, use your hands to pull the hinged position of the arc-shaped limit plate 6 backward and lift it upward. Fig. 9 The provided hinged connection mode enables the arc-shaped limit plate 6 to achieve a hinged effect while moving in the horizontal direction. Fig.10 As shown, the fixed shaft 706 moves from the closed area of ​​the U-shaped area of ​​the fitting groove 701 to the open area. In this process, the outer ring 707 is rotated to provide a rotational force. After the upward lifting action is completed, the fixed shaft 706 is completely disengaged from the fitting groove 701. At the same time, the ball 518 is also disengaged from the slot 512, resulting in double insurance failure. Since the spring of the telescopic part 515 is in a tightened state in the initial state, the spring of the telescopic part 515 recovers after the insurance fails and pulls the arc-shaped limit plate 6 to the position as shown in FIG. Fig.12 The state shown, and in this process, the arc-shaped limit plate 6 is detached to expose the slot 12, which is convenient for personnel to observe the connection between the connecting part 2 and the anchor rod;

[0070] 2. In Fig.12Since the trapezoidal rods 711 on the arc-shaped limit plates 6 in the upper and lower directions are not in the same position and are tilted, the structure can simulate an incomplete internal thread structure, and in this state, it can adapt to the rapid fitting of the exposed anchor rod. Since the telescopic part 515 can adjust the distance between the two arc-shaped limit plates 6, it can adapt to anchor rods of different diameters. When the incomplete thread structure formed by the upper and lower arc-shaped limit plates 6 contacts the thread protrusion of the anchor wall, the micro-drive motor 507 provides driving force and drives the rotating bearing 506 to rotate through the transmission gear 508 and the driven gear 509. At this time, the fixed block 510 and the arc-shaped limit plate 6 rotate at the same time and advance forward on the surface of the anchor rod along the thread structure formed between the trapezoidal rods 711. In this process, the rotating outer ring 707 provides an auxiliary rolling effect, so that the anchor rod can reach the hollow plate 505 more smoothly. In this state, it is necessary to manually hold the handle 11 to enable the pushing action to be performed.

[0071] 3. After the above actions are completed, it should be added that the distance from the end of the arc-shaped limit plate 6 to the fixed block 510 is the same as the position where the hollow plate 505 reaches the measuring part 3, that is, when the end of the arc-shaped limit plate 6 reaches the ground and the arc-shaped limit plate 6 is subsequently removed, the fixed block 510 is connected to the ground as the near point, so that it is possible to know at what time the connection part 2 is connected to the threaded part of the anchor rod without measuring. In the process of slope experiment, the experimental site sometimes cannot provide an anchor point with the ground. At this time, in the case of stone ground, the telescopic part 515 forms a clamping to provide an anchor point through the arc-shaped limit plate 6;

[0072] 4. In most cases, the anchor rod provides support force for the soft foundation. At this time, the trapezoidal rod 711 on the single arc-shaped limit plate 6 can be flipped around the center point into an arch bridge shape by adjusting the loose nut 709. At this time, the position of the cross groove 712 is raised relative to the arc-shaped limit plate 6 due to the flipping action. At this time, the other trapezoidal rod 711 is rotated to make the two trapezoidal rods 711 vertical. In this state, the warped edge of the unflipped trapezoidal rod 711 and the cross groove 712 of the flipped trapezoidal rod 711 are engaged at the same height. In this state, the arc-shaped limit plate 6 is drilled into the soft bottom surface under the action of the micro-drive motor 507 to provide anchor force. At this time, the sand cannot be easily moved in the structure, thereby ensuring the stability of the anchor.
