DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present 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 are within the scope of protection of the present invention.

[0025] See also Figures 1 to 4 The present invention provides a technical solution: a precise fixture displacement measuring device, comprising a workbench 1, the upper surface of the workbench 1 is fixedly connected with a supporting vertical plate 2, the surface of the supporting vertical plate 2 is hinged with a movable arm 3 and a movable arm 4, the tops of the movable arm 3 and the movable arm 2 4 are both hinged with a translation plate 5, and the upper surfaces of the two translation plates 5 are both provided with fixing components for fixing fixtures;

[0026] A dial indicator 6 is hingedly connected to the surfaces of the movable arm 1 3 and the movable arm 2 4 , and also includes a driving component for driving the movable arm 1 3 and the movable arm 2 4 to move closer or open.

[0027] When a pull-out test is performed on a fixture such as an anchor rod, the two ends of the anchor rod are respectively passed through the fixing components on both sides, and the two ends of the anchor rod are fixed by operating the fixing components. Then the driving component is operated to rotate the tops of the movable arm 1 3 and the movable arm 2 4 in the direction away from each other, thereby driving the two fixing components to move in opposite directions, and the pull-out test is performed on the anchor rod. Then, the value of the dial gauge 6 is read, that is, the displacement distance of the anchor rod stretching is fed back, which is simple and practical.

[0028] Furthermore, the driving component includes a double-axis motor 7 fixedly connected to the upper surface of the workbench 1, and the two output shafts of the double-axis motor 7 are fixedly connected with threaded rods 8, and the two threaded rods 8 are arranged axially symmetrically, and the surfaces of the two threaded rods 8 are threadedly connected with moving blocks 9, and the lower surfaces of the two moving blocks 9 are slidably connected to the upper surface of the workbench 1, and the tops of the two moving blocks 9 are hinged with articulated arms 26, and the ends of the two articulated arms 26 are respectively hinged to the bottoms of the movable arm 1 3 and the movable arm 2 4. Starting the double-axis motor 7 can drive the threaded rods 8 on both sides to rotate synchronously, and the two moving blocks 9 are moved away from each other to the two sides through the rotation of the threaded rods 8 and the threaded cooperation between them and the moving blocks 9. In this process, the tops of the movable arm 1 3 and the movable arm 2 4 are rotated in the direction away from each other through the transmission of the articulated arms 26, thereby driving the two fixed components to move in opposite directions.

[0029] Furthermore, the surface of the supporting vertical plate 2 is also hinged with auxiliary arm 10 and auxiliary arm 2 11, the auxiliary arm 10 is arranged in parallel with the movable arm 1 3, the auxiliary arm 2 11 is arranged in parallel with the movable arm 2 4, and the surfaces of the two translation plates 5 are respectively hinged with the tops of the auxiliary arm 10 and the auxiliary arm 2 11. By adding the auxiliary arm 10 and the auxiliary arm 2 11, and because the auxiliary arm 10 is arranged in parallel with the movable arm 1 3, and the auxiliary arm 2 11 is arranged in parallel with the movable arm 2 4, then under the drive of the movable arm 1 3 and the movable arm 2 4, the two translation plates 5 drive the fixed parts to translate in a circular trajectory, thereby reducing the possibility of anchor bending, thereby improving the accuracy of the test displacement distance data.

[0030] In order to further improve the accuracy of the test displacement distance data, further, it also includes a control component for automatically controlling the dual-axis motor 7 to shut down when the firmware is broken.

[0031] Further, the control component includes a fixing plate 12 fixedly connected to the side of the supporting vertical plate 2, a controller 13 and a supporting frame 14 are fixedly connected to the surface of the fixing plate 12, a mounting plate 15 is fixedly connected to the top of the supporting vertical plate 2, a plurality of laser emitters 16 are fixedly connected to the upper surface of the mounting plate 15, and a laser receiver 17 for receiving the laser emitters 16 is fixedly connected to the surface of the supporting frame 14;

[0032] The output end of the laser transmitter 16 is connected to the receiving end of the controller 13 for signal connection, and the output end of the controller 13 is connected to the receiving end of the dual-axis motor 7 for signal connection.

[0033] During the process of pulling out the anchor rod, the laser transmitter 16 and the laser receiver 17 are located directly below and directly above the anchor rod, respectively. Then, when the anchor rod breaks, the light emitted by the laser transmitter 16 will instantly pass through the broken part of the anchor rod and shoot toward the laser receiver 17. The laser receiver 17 converts the received light signal into an electrical signal to the controller 13. After receiving the signal, the controller 13 can control the dual-axis motor 7 to turn off, ensuring that the dual-axis motor 7 can stop running at the moment the anchor rod breaks, avoiding further movement of the boom 1 3 and the boom 2 4, thereby further improving the accuracy of the test displacement distance data.

[0034] Furthermore, the fixing component includes a placing platform 18 fixedly connected to the upper surface of the translation plate 5, a clamping block 19 fixedly connected to the surface of the placing platform 18, and a clamping block 20 slidably connected, a support seat 21 fixedly connected to the upper surface of the placing platform 18, a bolt 22 fixedly connected to the surface of the clamping block 20, and an internal threaded through hole threadedly connected to the bolt 22 is provided on the surface of the support seat 21. By twisting the bolt 22 and through the threaded engagement between the bolt 22 and the support seat 21, the clamping block 20 is moved toward the clamping block 19, so that the two ends of the anchor rod can be fixed.

[0035] In order to shield the parts of the driving components and ensure the beauty of the entire device, a shielding box 23 is fixedly connected to the upper surface of the workbench 1, and a transparent window 24 for observing the dial indicator 6 is opened on the surface of the shielding box 23. The operator can observe the value of the dial indicator 6 through the transparent window 24.

[0036] In order to further support the threaded rod 8 and make its rotation process more stable, further, the surface of the threaded rod 8 is connected to a stabilizing plate 25 for fixed-axis rotation, and the lower surface of the stabilizing plate 25 is fixedly connected to the upper surface of the workbench 1.

[0037] Working principle: When the precise fixture displacement measuring device performs a pull-out test on a fixture such as an anchor rod, the two ends of the anchor rod are passed through the fixing parts on both sides.

[0038] Then, by twisting the bolt 22 and through the threaded cooperation between the bolt 22 and the support seat 21, the clamp block 20 is moved toward the clamp block 19, so that the two ends of the anchor rod can be fixed.

[0039] Then, the dual-axis motor 7 is started to drive the threaded rods 8 on both sides to rotate synchronously. The threaded rods 8 rotate and the threads cooperate with the moving blocks 9, so that the two moving blocks 9 move away from each other on both sides. In this process, the tops of the movable arm 3 and the movable arm 2 4 rotate away from each other through the transmission of the articulated arm 26, thereby driving the two fixed parts to move in opposite directions. The anchor rod is subjected to a pull-out test, and then the value of the dial indicator 6 is read, which is the displacement distance of the anchor rod stretching. It is simple and practical.

[0040] By adding auxiliary arm 10 and auxiliary arm 2 11, and because auxiliary arm 10 is arranged parallel to boom 1 3, and auxiliary arm 2 11 is arranged parallel to boom 2 4, then under the drive of boom 1 3 and boom 2 4, the two translation plates 5 drive the fixed component to translate in a circular trajectory, thereby reducing the possibility of anchor bending, and thereby improving the accuracy of the test displacement distance data.

[0041] During the process of pulling out the anchor rod, the laser transmitter 16 and the laser receiver 17 are located directly below and directly above the anchor rod, respectively. Then, when the anchor rod breaks, the light emitted by the laser transmitter 16 will instantly pass through the broken part of the anchor rod and shoot toward the laser receiver 17. The laser receiver 17 converts the received light signal into an electrical signal to the controller 13. After receiving the signal, the controller 13 can control the dual-axis motor 7 to turn off, ensuring that the dual-axis motor 7 can stop running at the moment the anchor rod breaks, avoiding further movement of the boom 1 3 and the boom 2 4, thereby further improving the accuracy of the test displacement distance data.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
