Description

Technical Field

[0001] The utility model relates to the technical field of anchor rod detection, and further relates to a portable anchor rod detection device. Background Art

[0002] As is known to all, a slope anchor is a kind of support rod fixed in the embankment slope and road slope. After the slope anchor is fixed, it is generally used to achieve support for the external frame.

[0003] However, after this type of slope anchor is fixed on the slope, its fixing strength cannot be directly reflected. In order to ensure its stability when supporting the external frame, it is generally required to perform a pull-out test on the fixed slope anchor.

[0004] For example, the new slope anchor pull-out test support disclosed in Chinese utility model patent publication number: (CN215256271U) includes a support cylinder, a swing seat and an articulated seat. The bottom of the support cylinder is hinged to the articulated seat through the swing seat, and can achieve a maximum rotation of 45 degrees, so that the bottom surface of the support cylinder can be axially connected to the slope anchor and apply a vertical pulling force to the slope anchor, which can improve the success rate of the test and improve the authenticity of the test data.

[0005] However, in the process of implementing the present invention, it was found that there are at least the following problems: since the support cylinder is connected to the articulated seat, but the support cylinder is heavy, if the support cylinder mounted outside the anchor rod is not in a vertical state, the support cylinder is likely to drive the free end of the anchor rod to deflect downward under the influence of gravity. At this time, the force applied by the support cylinder to the anchor rod will also be deflected, making it difficult to meet the axial pulling force applied by the anchor rod, and the experimental data has not been improved.

[0006] In view of this, this application is hereby filed. Utility Model Content

[0007] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a portable anchor rod detection device.

[0008] The utility model is achieved through the following technical solutions:

[0009] An embodiment of the present utility model provides a portable anchor rod detection device, including a support base and a support cylinder, wherein the support base and the support cylinder are hinged, and further comprising a plurality of limit members, wherein the plurality of limit members are arranged at intervals around the support cylinder, and the limit members have a first portion and a second portion with adjustable spacing, wherein the first portion is connected to the support base, and the second portion is connected to the support cylinder.

[0010] Because the multiple stoppers are connected between the support base and the support cylinder and spaced around the support cylinder, the multiple stoppers can be considered a support mechanism or a traction mechanism located between the support base and the support cylinder. Since the support base and the support cylinder are hinged, by adjusting the spacing between the first and second portions of different stoppers, the multiple stoppers can apply different supporting forces or traction forces to the support cylinder, thereby causing the support cylinder to rotate or remain stationary relative to the support base.

[0011] Furthermore, the support base is connected to an articulated seat, a ball head cavity is provided in the articulated seat; the support cylinder is connected to a swing seat, a swing seat is provided with a swing ball head; the swing ball head is constrained in the ball head cavity and can rotate.

[0012] Furthermore, the swing seat and the support cylinder are connected by a flange;

[0013] It also includes a limit plate, which is arranged between the swing seat and the flange of the support cylinder, and the limit plate is connected to all the second parts.

[0014] Furthermore, all the first parts are evenly spaced around the axis of the support base, and all the second parts are evenly spaced around the axis of the support cylinder.

[0015] Furthermore, the limiting member is a telescopic rod, and both ends of the telescopic rod serve as the first portion and the second portion respectively. The two ends of the telescopic rod are connected to the support base and the support cylinder respectively.

[0016] Furthermore, the telescopic rod is a hydraulic telescopic rod.

[0017] Furthermore, both ends of the telescopic rod are universally hinged to the support base and the support cylinder respectively.

[0018] Furthermore, the number of the telescopic rods is at least 3.

[0019] Furthermore, the support base has a fixing hole.

[0020] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0021] An embodiment of the present utility model provides a portable anchor rod detection device, which, through the arrangement of multiple limit members, can adjust or limit the rotational position of the support cylinder relative to the support base by adjusting the distance between the first part and the second part, thereby prompting the support cylinder to maintain an angle that is adapted to the axial direction of the anchor rod, avoiding the situation where the support cylinder drives the free end of the anchor rod to deflect downward under the influence of gravity, and ensuring that the support cylinder can apply the required pulling force to the anchor rod in the axial direction, thereby improving the success rate of the test and improving the authenticity of the test data.

[0035] Example 1

[0036] like Figure 1-2As shown, a portable anchor rod detection device includes a support base 1 and a support cylinder 2, the support base 1 and the support cylinder 2 are hinged, and the support base 1 and the support cylinder 2 have through holes for the anchor rod 4 to pass through, and also includes a plurality of limit members 3, a plurality of the limit members 3 are arranged at intervals around the support cylinder 2, and the limit members 3 have a first portion and a second portion with adjustable spacing, the first portion is connected to the support base 1, and the second portion is connected to the support cylinder 2.

[0037] Because the plurality of stoppers 3 are connected between the support base 1 and the support cylinder 2 and are spaced apart around the support cylinder 2, the plurality of stoppers 3 can be considered a supporting mechanism or a pulling mechanism located between the support base 1 and the support cylinder 2. Since the support base 1 and the support cylinder 2 are hinged, by adjusting the spacing between the first and second portions of different stoppers 3, the plurality of stoppers 3 can apply different supporting forces or pulling forces to the support cylinder 2, thereby causing the support cylinder 2 to rotate or remain stationary relative to the support base 1.

[0038] To sum up, through the arrangement of multiple limit members 3, the rotation position of the support cylinder 2 relative to the support base 1 can be adjusted or limited by adjusting the distance between the first part and the second part, thereby prompting the support cylinder 2 to maintain an angle that is axially adapted to the anchor rod 4, avoiding the situation where the support cylinder 2 drives the free end of the anchor rod 4 to deflect downward under the influence of gravity, and ensuring that the support cylinder 2 can apply the required pulling force to the anchor rod 4 in the axial direction, thereby improving the success rate of the test and improving the authenticity of the test data.

[0039] At the same time, the detection device as a whole does not add too many components to the original technology, so the overall specifications of the detection device are still small and easy to carry.

[0040] In one or more embodiments, the support base 1 is connected to a hinge seat 11, and a ball head cavity is provided in the hinge seat 11; the support cylinder 2 is connected to a swing seat 21, and a swing ball head is provided in the swing seat 21; the swing ball head is constrained in the ball head cavity and can rotate.

[0041] Here, the rotation between the support base 1 and the support cylinder 2 is realized only through a single node of the mutually cooperating swinging ball head and the ball head cavity, so that the rotation center point between the support base 1 and the support cylinder 2 is fixed to the center of the swinging ball head, which facilitates the restriction of the rotation of the support cylinder 2 by multiple limit members 3.

[0042] Furthermore, the swing seat 21 and the support cylinder 2 are connected by a flange; the detection device also includes a limit plate 22, which is arranged between the swing seat 21 and the flange of the support cylinder 2, and is fixed to the swing seat 21 and the support cylinder 2 under the clamping of the flanges on both sides. The limit plate 22 is connected to all the second parts. At this time, the second part and the support cylinder 2 are indirectly connected through the limit plate 22.

[0043] By adding a limit plate 22 to assume the connection of the limit member 3, there is no need to carry out construction on the support cylinder 2 or the swing seat 21 to connect with the limit member 3, thereby avoiding damage to the support cylinder 2 caused by construction or when the limit member 3 limits the rotation position of the support cylinder 2, thereby increasing the service life of the support cylinder 2; and the limit plate 22 is easy to replace.

[0044] In one or more embodiments, the limiting member 3 may include a screw connected to the support base 1 and at least two nuts sleeved on the screw, wherein the other end of the screw passes through the support cylinder 2 or a component connected to the support cylinder 2, and the two nuts are respectively blocked on both sides of the support cylinder 2 or a component connected to the support cylinder 2. At this time, one end of the screw is connected to the support base 1 as the first part, and the part where the two nuts are located is the second part. By adjusting the positions of the two nuts on the screw, the distance between the first part and the second part is adjusted, thereby adjusting or limiting the rotation position of the support cylinder 2 relative to the support base 1;

[0045] The limiting member 3 can also be a telescopic rod. Specifically, the limiting member 3 is a telescopic rod, and the two ends of the telescopic rod serve as the first part and the second part respectively. The two ends of the telescopic rod are respectively connected to the support base 1 and the support cylinder 2.

[0046] It should be noted that when the support cylinder 2 is maintained at an angle that is axially adapted to the anchor rod 4, the reaction force exerted on the support cylinder 2 toward the support seat when the support cylinder 2 applies a pulling force to the anchor rod 4 is mainly borne by the articulated seat 11, and the limiter 3 does not need to participate or participate too much in bearing the reaction force. The limiter 3 is mainly to resist the gravity that causes the support rod and the anchor rod 4 to deflect downward. Therefore, when selecting the limiter 3, the force strength of the limiter 3 does not need to be considered or the pulling force exerted by the support cylinder 2 on the anchor rod 4 needs to be taken into consideration too much.

[0047] Among them, any rod with telescopic function and capable of bearing corresponding pressure after telescoping can be used as the telescopic rod. Specifically, the telescopic rod can be a hydraulic telescopic rod, wherein the hydraulic telescopic rod after telescoping can withstand greater pressure and can ensure the limiting ability of the limiter 3 on the support rod.

[0048] Among them, the connection between the telescopic rod and the support base 1 and the support cylinder 2 is preferably a rotating connection. More preferably, the two ends of the telescopic rod are universally hinged to the support base 1 and the support cylinder 2 respectively, so as to facilitate the free rotation of the support cylinder 2 as a whole.

[0049] Specifically, all the first parts are evenly spaced around the axis of the support base 1 (i.e., the axis of the through hole of the support base 1), and all the second parts are evenly spaced around the axis of the support cylinder 2 (i.e., the axis of the through hole of the support cylinder 2), thereby making the distribution of the limit member 3 more regular, and facilitating the adjustment of the extension and contraction amount of the limit member 3.

[0050] The number of telescopic rods is preferably at least 3, and the support cylinder 2 is restricted by at least 3 telescopic rods to ensure that the support cylinder 2 that can rotate in all directions can be effectively and reliably restricted.

[0051] Specifically, there are four telescopic rods, which are respectively connected to the corners of the support base 1 and the limiting plate 22 .

[0052] In one or more embodiments, the support base 1 has a fixing hole 12, and the support base 1 can be fixed on the inclined surface by inserting an anchor nail in the fixing hole 12, so as to prevent the detection device as a whole from sliding down the inclined surface or having a tendency to slide down, causing unnecessary squeezing of the anchor rod 4.

[0053] The above is a preferred embodiment of the present invention. Technicians in the field of the present invention can also change and modify the above embodiment. Therefore, the present invention is not limited to the above specific embodiment. Any obvious improvements, replacements or deformations made by technicians in this field on the basis of the present invention are within the scope of protection of the present invention.
