[0025] Embodiment 1

[0026] Refer to the appendix Figure 1-6, this application provides an external pressure load test device for reinforced concrete drain pipes, including a frame 1, a gantry 2, a turntable 3 and a support member 4. A table board 5 is provided on the frame 1, and the table board 5 is fixedly installed on the frame 1. The gantry 2 is fixedly installed on the table board 5. The turntable 3 is rotatably connected to the table board 5. By rotating the turntable 3, the loading station and the testing station are switched. The support member 4 is installed on the table board 5. The gantry 2 is provided with a pressing plate 6, and the pressing plate 6 is movably connected to the gantry 2. The pressing-down station of the pressing plate 6 is the testing station, and the outside of the pressing plate 6 is the loading station. The pressing plate 6 is used to press down to apply an external pressure load to the concrete drain pipe 26. When the pressing plate 6 presses down for testing, the support member 4 is directly below the pressing plate 6, and the turntable 3 is supported by the support member 4 to prevent the turntable 3 from deforming or breaking and affecting the test results. The turntable 3 is provided with a positioning block 7, and the rotation of the concrete drain pipe 26 is restricted by the positioning block 7, which is convenient for measurement and loading. During operation, the tester first places the concrete drain pipe 26 at the loading station, rotates the turntable 3 to rotate the placed concrete drain pipe 26 to the testing station, the pressing plate 6 presses down to apply a load for testing, and at the same time the support member 4 supports the turntable 3. After the test is completed, the turntable 3 is rotated to switch the tested concrete drain pipe 26 to the loading station for unloading, and at the same time the newly loaded concrete drain pipe 26 is switched to the testing station for testing, and so on in a cycle. Obviously, if the concrete drain pipe 26 breaks during the test, the tester only needs to rotate the turntable 3 to rotate the broken concrete drain pipe 26 to the outside loading station for convenient cleaning, without the need for personnel to clean the slag under the pressing plate 6, avoiding accidental falling of the pressing plate 6 and injuring people, facilitating cleaning, and not requiring operation under the hanging object, improving the safety factor of the tester's operation.

[0027] Specifically, the table board 5 is provided with a rotating device 8. The output end of the rotating device 8 is connected to the turntable 3, and the other end is fixedly connected to the table board 5. The rotating device 8 is used to automatically rotate the turntable 3 to automatically switch the working stations, liberating labor and improving efficiency. The rotating device 8 can be a motor, a rotating cylinder, a hydraulic cylinder or a gear-rack transmission structure, etc. By rotating the turntable 3 through the rotating device 8, the structure is simple, convenient for maintenance and has high precision.

[0028] Specifically, the support member 4 includes a first hydraulic cylinder 9, a first hinge seat 10, a second hinge seat 11, a hinge member 12, and a support plate 13. The support plate 13 is movably connected to the first hinge seat 10. The first hinge seat 10 is provided with a slide rail 27, and the slide rail 27 is engaged with a slider 28. The slider 28 is connected to the support plate 13, and the support plate 13 moves up and down along the slide rail 27. The support plate 13 is used to contact and support the turntable 3. When the support plate 13 rises to contact the turntable 3, it supports the turntable 3. When it descends and leaves the turntable 3, it can prevent friction or jamming when the turntable 3 rotates. One end of the first hydraulic cylinder 9 is hinged to the first hinge seat 10, and the other end is hinged to the hinge member 12. The hinge member 12 is hinged to the second hinge seat 11. The hinge member 12 is provided with a bearing follower 14, and the support plate 13 is provided with a cam groove 15 that cooperates with the bearing follower 14. During operation, when the first hydraulic cylinder 9 extends, it pushes the hinge member 12 forward. At this time, the hinge member 12 rotates around its hinge point with the second hinge seat 11 (hereinafter referred to as: the second hinge point) to drive the movement of the bearing follower 14. The bearing follower 14 moves in an arc along with the hinge member 12. The cooperation between the bearing follower 14 and the cam groove 15 drives the support plate 13 to rise. When the support plate 13 rises to contact the turntable 3, the pressure plate 6, the bearing follower 14, and the second hinge point are just self-locked on the same straight line (the force direction and the movement direction are on the same straight line). The pressure plate 6 presses down for testing. At this time, the support force of the support plate 13 on the turntable 3 is the largest, which can well support the turntable 3. After the test is completed, the first hydraulic cylinder 9 contracts, driving the hinge member 12 to reset, and at the same time driving the bearing follower 14 to reset. The cooperation between the bearing follower 14 and the cam groove 15 enables the support plate 13 to descend and reset, leaving the turntable 3. By driving the support plate 13 to rise and fall through the first hydraulic cylinder 9, the support plate 13 can rise to contact the turntable 3 for support and descend to leave the turntable 3 to prevent friction or jamming when the turntable 3 rotates. The structure is ingenious, and the maximum support force is achieved by structural self-locking, which is suitable for popularization and application.

[0029] Specifically, the gantry 2 is provided with a second hydraulic cylinder 16. The output end of the second hydraulic cylinder 16 is connected to the pressure plate 6. The pressure plate 6 is driven by the second hydraulic cylinder 16 to press down, and the pressure is large, which can meet different external pressure loads.

[0030] Specifically, the positioning block 7 is provided with a guiding inclined surface 17. Through the guiding inclined surface 17, it is convenient for the tester to place the concrete drain pipe 26. After being placed, the concrete drain pipe 26 will not be crooked under the guiding action, which will affect the test.

[0033] Preferably, the hinge member 12 is provided with a top block 19, and the second hinge seat 11 is provided with a limit buffer bolt 20 and a nut 21. Buffering is carried out by the contact between the top block 19 and the limit buffer bolt 20. By adjusting the positions of the limit buffer bolt 20 and the top block 19, it is convenient to better adjust the pressing plate 6, the bearing follower 14 and the second hinge point to be on the same straight line to achieve self-locking. The structure is simple and the operation is convenient.

[0034] Preferably, the positioning block 7 includes an adjustable positioning block 22, and the adjustable positioning block 22 is provided with a waist-shaped hole 23. The installation position of the adjustable positioning block 22 is adjusted through the waist-shaped hole 23 to correspond to concrete drain pipes 26 of different sizes.

[0035] Preferably, the limit buffer bolt 20 is provided with a urethane rubber pad 24, and the urethane rubber pad 24 is inlaid on the limit buffer bolt 20 for buffering, reducing damage caused by impact and improving the service life.

[0036] Preferably, the gantry 2 is provided with a vertical plate 25, the vertical plate 25 is provided with a horizontal plate 29, the vertical plate 25 is provided with a plurality of mounting holes 251, the horizontal plate 29 is bolted and installed on the mounting holes 251 of the vertical plate 25, and the second hydraulic cylinder 16 is installed on the horizontal plate 29. The horizontal plate 29 realizes the adjustment of the height position of the horizontal plate 29 by being replaced and installed in different mounting holes 251, and further realizes the switching of different height positions of the second hydraulic cylinder 16, and further can adapt to the tests of concrete drain pipes 26 of different sizes. The structure is simple and the installation operation is convenient.
