Description

Technical Field

[0001] This utility model relates to the field of detection auxiliary device technology, specifically an anchor bolt pull-out detection auxiliary device. Background Technology

[0002] An anchor bolt is a tension member that connects one end to an external load-bearing component and the other end to stable rock and soil, transmitting tensile force to the rock and soil mass. Anchor bolts mainly serve a support function, enhancing the stability of surrounding rock and slopes, supporting and extending the service life of surrounding rock and slopes, and improving the bearing capacity of surrounding rock and slopes. The content of anchor bolt testing and monitoring should be determined according to the stage of the rock and soil anchor bolt project, including tests to provide a basis for design before construction, tests and monitoring to provide a basis for quality and safety during construction, tests to provide a basis for acceptance after construction, and monitoring to provide a basis for safe operation. Among them, the anchor bolt pull-out testing equipment generally consists of a manual hydraulic pump, a hollow hydraulic cylinder, a digital pressure gauge, a high-pressure oil pipe with a quick-connect coupling, anchors, tie rods, and conversion joints.

[0003] During on-site testing, the tie rod passes through the hollow hydraulic cylinder, with one end connected to the anchor rod to be tested on-site, and the other end fixed to the hollow hydraulic cylinder by the anchor. A high-pressure oil pipe with a quick connector is connected to the hollow hydraulic cylinder at one end and to a manual hydraulic pump at the other end. The anchor rod pull-out force is tested by pressurizing the manual hydraulic pump (the pressure is displayed on a digital pressure gauge).

[0004] The following problems often occur during on-site testing:

[0005] 1. Currently, the tie rods on the market are connected to the anchor rod to be tested by thread. The pre-reserved end of the anchor rod to be tested needs to be pre-treated in advance. If the treatment is not done properly, it is easy to cause problems such as misjudgment of test results and failure to test. Moreover, the treatment process is cumbersome.

[0006] 2. During on-site testing, the hollow hydraulic cylinder needs to apply a reaction force to the rock (soil) surrounding the anchor bolt to be tested. Due to unevenness, instability, or the presence of steel reinforcement mesh in the surrounding rock (soil), an auxiliary pad is required for operation. However, this pad cannot be used when there is steel reinforcement mesh or the rock (soil) is particularly uneven.

[0007] Therefore, an auxiliary device for anchor bolt pull-out detection is needed to improve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] Embodiment: Please refer to Figures 1-5 The utility model relates to an anchor rod pullout detection auxiliary device shown in a kind of anchor rod pullout detection auxiliary device, including backing plate 1, backing plate 1 outer wall is equipped with bottom column 2, and the connecting hole 3 is opened in the outer wall of bottom column 2 one side and located backing plate 1, and the hollow hydraulic cylinder 4 is installed on the outer wall of backing plate 1, and the hollow hydraulic cylinder 4 one end is equipped with pull rod assembly 5, and the quick coupling 6 is arranged on the outer wall of hollow hydraulic cylinder 4, and the high-pressure oil pipe 7 is installed at the port of quick coupling 6, and the high-pressure oil pipe 7 one end is connected with hand-operated hydraulic pump 8, and the spherical connector 9 is installed on the outer wall of bottom column 2, and the threaded sleeve 10 is installed on the outer wall of spherical connector 9, and the second threaded rod 11 is threadedly connected on the inner wall of threaded sleeve 10, and the outer wall of backing plate 1 and bottom column 2 is respectively provided with level 12;

[0028] In the embodiment, specific reference is made to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 And Figure 5 , pull rod assembly 5 includes first pull rod 501, and the first pull rod 501 one end is threadedly connected on the inner wall of hollow hydraulic cylinder 4, and the first pull rod 501 one end is connected with hollow hydraulic cylinder 4 and extends to the connecting hole 3 side, and the limit block 502 is threadedly installed on the outer wall of first pull rod 501, and the round hook 503 is arranged on the one end of first pull rod 501, and the limit block 502 is located on the one side of hollow hydraulic cylinder 4, and the round hook 503 is located on the one side of second threaded rod 11.

[0029] Among them, bottom column 2 is provided with multiple groups and is located on the outer wall of backing plate 1 respectively, and bottom column 2 is installed on the outer wall of backing plate 1 by welding, and hollow hydraulic cylinder 4 and bottom column 2 are located on the opposite outer walls of backing plate 1 respectively, and the fixing ring 13 is arranged on the outer wall of hollow hydraulic cylinder 4, and the digital pressure gauge 14 is arranged on the outer wall of hand-operated hydraulic pump 8, and the spherical connector 9 is provided with multiple groups and is located on the outer wall of bottom column 2 respectively, and the threaded sleeve 10 is provided with multiple groups and is located on the outer wall of spherical connector 9 respectively, and the second threaded rod 11 and spherical connector 9 are located at the opposite ports of threaded sleeve 10 respectively, and the level 12 is provided with two groups and is located on the outer wall of backing plate 1 and bottom column 2 respectively, and the reinforcing rib is arranged on the inner wall of bottom column 2, to increase the stability of support structure.

[0030] One end of the spherical connector 9 is provided with a threaded groove to facilitate connection with the threaded sleeve 10. Since the second threaded rod 11 is fixed at the anchor rod to be tested, when the threaded sleeve 10 in one position rotates, the second threaded rod 11 in other positions is fixed, which has a limiting effect on the pad 1. This allows the bottom post 2 on the side where the threaded sleeve 10 rotates and the spherical connector 9 to rotate, thereby adjusting the angle of the pad 1. By adjusting the position of the threaded sleeve 10 in sequence, the angle of the pad 1 can be adjusted so that the pad 1 remains horizontal.

[0031] In this design, the anchor pull-out testing auxiliary device connects one end of a first pull rod 501 to the inner wall of a hollow hydraulic cylinder 4 via a threaded connection.

Direct connection or connection via a steel cable is possible, eliminating the need for pre-processing the pre-reserved end of the anchor rod. This solves the problem of current market practices where pull rods connect to the anchor rod via threads, requiring pre-processing of the pre-reserved end, which can easily lead to misjudgments or even failure to test if not properly processed, and is also cumbersome.
