Description

Technical Field

[0001] This utility model relates to the field of workpiece strength testing technology, and in particular to a strength testing device for a locking foot anchor pipe positioning fixture. Background Technology

[0002] In tunnel excavation, slope protection, and other engineering construction, anchor pipes are key components for enhancing the stability of the engineering structure, and the accuracy of their installation position directly affects the support effect. The installation and positioning of anchor pipes usually rely on positioning fixtures, which need to withstand the external forces during the anchor pipe installation process. Therefore, the strength of the fixtures themselves is an important prerequisite for ensuring the installation accuracy of the anchor pipes and the safety of subsequent projects.

[0003] Currently, the industry mostly uses simplified methods to test the strength of anchor pipe positioning fixtures. In some scenarios, force is applied to the fixture manually using hand tools. This method makes it difficult to accurately control the magnitude and direction of the force, and the test results are easily affected by human operation, resulting in large errors. Some testing devices can only be adapted to positioning fixtures of specific specifications. When the dimensions of the first and second mounting parts of the fixture or the spacing of the positioning holes change, the device is inconvenient to adjust and adapt, requiring the replacement of special testing components, which not only increases the testing cost but also extends the testing cycle.

[0004] To address the aforementioned issues, this utility model document proposes a strength testing device for a locking anchor pipe positioning fixture. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as insufficient accuracy and large errors in strength testing of anchor pipe positioning fixtures, difficulty in adapting to different specifications of fixtures, and the resulting increase in cost and extended cycle. Therefore, this invention proposes a strength testing device for anchor pipe positioning fixtures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A strength testing device for a locking anchor pipe positioning fixture includes: The positioning fixture body consists of two first mounting parts and one second mounting part.

Positioning holes are provided at the positions of the second mounting parts near the sides and the two first mounting parts near the bottom. The base has a limiting frame fixedly installed on its top. The limiting frame passes through the central slot of the positioning fixture body and is used to position the positioning fixture body. A sliding groove is provided on the top of the base near one side, and a sliding seat is slidably disposed in the sliding groove. The testing mechanism includes a rotating rod and two testing rods, each of which passes through two positioning holes on a corresponding side. The rotating rod is used to drive the two testing rods to rotate in order to perform a strength test on the main body of the positioning fixture.

[0007] In one possible design, the detection mechanism includes a mounting frame fixedly installed on the top of the sliding seat. The rotating rod is rotatably installed inside the mounting frame, and both ends of the rotating rod rotatably pass through both sides of the mounting frame. The rotating rod is divided into two parts by the mounting frame, and two mounting grooves are formed on the outer circumference of the rotating rod. The two mounting grooves are respectively located in the two parts of the rotating rod. A mounting block is slidably disposed in the mounting groove, and a tube is fixedly installed at one end of the mounting block. The tube is located outside the mounting groove and is used to insert and cooperate with one end of an adjacent detection rod.

[0008] In one possible design, the inner wall of the mounting groove is provided with multiple positioning grooves, and the mounting block is slidably connected to the corresponding positioning grooves by a protrusion fixedly provided on the outer wall; a through groove is provided on one side of the mounting groove, and a threaded post is fixedly installed at the end of the mounting block away from the insertion tube. One end of the threaded post passes through the adjacent through groove, and a fastening nut is threaded on the outer wall of the threaded post to fix the position of the mounting block in the mounting groove.

[0009] In one possible design, the detection mechanism further includes a mounting plate disposed at one end of the rotating rod, with a fixed column fixedly mounted on one side of the mounting plate at a position offset from the center; a movable block is slidably mounted on the top of the sliding seat, and a clearance groove is formed inside the movable block, with one end of the fixed column passing through the clearance groove, and the outer wall of the fixed column slidingly engaging with the inner wall of the clearance groove; a second cylinder is fixedly mounted on the top of the sliding seat, with one end of the piston rod of the second cylinder engaging with one side of the movable block to drive the movable block to move horizontally, thereby driving the mounting plate to rotate.

[0010] In one possible design, the mounting plate is rotatably sleeved on the rotating rod near its end, and a locking screw is threaded through one side of the mounting plate; a collar is fixedly sleeved on the outer wall of the rotating rod, the collar cooperates with the mounting plate, and a through hole is opened on one side of the collar, and one end of the locking screw passes through the adjacent through hole to complete the locking between the mounting plate and the rotating rod.

[0011] In one possible design, a pressure sensor is fixedly mounted on one side of the moving block, and one end of the piston rod of the second cylinder is fixedly connected to the detection end of the pressure sensor to detect the thrust of the second cylinder; a second displacement sensor is fixedly mounted on the top of the sliding seat, the second displacement sensor is located on the side of the moving block away from the second cylinder, and the detection end of the second displacement sensor is fixedly connected to the adjacent side of the moving block to detect the displacement distance of the moving block.

[0012] In one possible design, a first cylinder and a first displacement sensor are fixedly installed on the bottom inner wall of the sliding groove.

One end of the piston rod of the first cylinder is fixedly connected to one side of the sliding seat, and the detection end of the first displacement sensor is fixedly connected to one side of the sliding seat to drive the sliding seat to move and detect its displacement distance.

[0013] In one possible design, a controller is fixedly installed on the bottom inner wall of the sliding groove, and the controller is electrically connected to the first cylinder, the first displacement sensor, the second cylinder, the pressure sensor, and the second displacement sensor.

[0014] In this application, before the equipment is started, the main body of the positioning fixture is first fitted into the limiting frame on the top of the base to complete the installation of the main body of the positioning fixture to be tested; then, the two insertion tubes are installed in the appropriate positions in the installation groove. During installation, the installation block slides with the positioning groove in the installation groove through the protrusion on the outer wall. After installation, the threaded column passes through the through groove and is locked by the fastening nut, thereby achieving stable installation of the two insertion tubes; then, the two detection rods are inserted through the corresponding positioning holes, and at the same time, the first cylinder is controlled to drive the sliding seat to move along the sliding groove. The first displacement sensor can monitor the sliding seat displacement distance in real time. With the precise movement of the sliding seat, it can be ensured that the end of the detection rod can be stably inserted into the corresponding insertion tube; After installation preparation is completed, the second cylinder is started, and its piston rod continuously applies force to the moving block. During this process, with the cooperation of the fixed column, the mounting plate continuously applies torque to the rotating rod, which allows the two detection rods to continuously press and detect the positioning fixture body. During the detection process, the pressure sensor continuously monitors the thrust value of the second cylinder to complete the data recording. When the pressure sensor reading reaches the appropriate standard and the main body of the positioning fixture does not exhibit deformation exceeding the standard, it indicates that the strength of the main body of the positioning fixture is qualified. When the main body of the positioning fixture deforms, the moving block will move forward, and the second displacement sensor will monitor the displacement distance of the moving block. When the displacement distance of the moving block exceeds the standard, it indicates that the strength of the main body of the positioning fixture is unqualified. During the test, the controller completes data synchronization and corresponding control for each electrical component. After the test, the sliding seat is reset under the drive of the first cylinder, and the test rod is pulled out from the insertion tube and the corresponding positioning hole. Then the corresponding positioning fixture body can be replaced to start a new round of testing.
