[0023] The fixed frame mechanism 2 includes a fixed frame 201 fixed to the workbench 1. Two first support rods 202 are fixedly connected inside the fixed frame 201, symmetrically arranged on the fixed frame 201, and on the same horizontal plane. The elastic drive roller mechanism 3 includes two first lifting grooves 301 formed on the side of the fixed frame 201, symmetrically arranged on the fixed frame 201. Two first springs 302 are fixedly connected to the fixed frame 201, symmetrically arranged on the fixed frame 201. The first springs 302 are fixedly connected to first sliders 303, which are located inside the first lifting grooves 301. The first sliders 303 and the fixed frame 201 are slidably connected. The first sliders 303 are rotatably connected to a drive roller 304. A first motor 305 is located on the outer side of one of the first sliders 303, and the output shaft of the first motor 305 is coaxially fixedly connected to the drive roller 304. The first feed pressure plate mechanism 4 includes a first hydraulic push rod 401 fixed on the fixed frame 201. The first hydraulic push rod 401 is fixedly connected to the first feed frame 402. The first feed frame 402 passes through the fixed frame 201 and is slidably connected to the fixed frame 201. The first feed frame 402 is fixedly connected to the lifting plate 403. The lifting plate 403 is slidably connected to the fixed frame 201. The lifting plate 403 is fixedly connected to the second spring 404. The end of the second spring 404 away from the lifting plate 403 is fixedly connected to the pressure plate 405. The pressure plate 405 is slidably connected to the fixed frame 201. The second feed pressure plate mechanism 8 has the same structure as the first feed pressure plate mechanism 4. The first linkage clamping mechanism 5 includes a gear seat 501 fixed on the lifting plate 403. The gear seat 501 is rotatably connected to a gear 502. The gear 502 meshes with a first rack 503. The first rack 503 passes through the lifting plate 403 and is slidably connected to the lifting plate 403. The first rack 503 is fixedly connected to a pressure plate 405. The gear 502 meshes with two second racks 504. The two second racks 504 are respectively positioned above and below the gear 502. The second racks 504 are fixedly connected to a pull plate. Rod 505 passes through the first feed frame 402 and is slidably connected to the first feed frame 402. Rod 505 is fixedly connected to the side clamping plate 506. The lifting plate 403 is provided with a first sliding groove 507, and the pressure plate 405 is provided with a second sliding groove 508. The side clamping plate 506 passes through the first sliding groove 507 and is slidably connected to the lifting plate 403. The side clamping plate 506 passes through the second sliding groove 508. The second linkage clamping mechanism 9 and the first linkage clamping mechanism 5 have the same structure.

[0024] Specifically, the floor slab is placed on the first support rod 202. At this time, the first spring 302 can push the first slider 303, which in turn pushes the drive roller 304, so that the drive roller 304 directly contacts the floor slab. Then the first motor 305 is turned on. The output shaft of the first motor 305 rotates, which drives the drive roller 304 to rotate, thereby driving the floor slab to move.

[0025] Additionally, if it is necessary to clamp and fix the floor slab, the first hydraulic push rod 401 is activated. The first hydraulic push rod 401 can drive the first feed frame 402 to move downward, thereby driving the lifting plate 403 to descend, and then driving the second spring 404 and pressure plate 405 to descend. When the pressure plate 405 contacts the floor slab, the first hydraulic push rod 401 is activated again, which can make the lifting plate 403 descend further. Since the pressure plate 405 has already contacted the floor slab, it will no longer descend. At this time, the second spring 404 is compressed, the relative position of the first rack 503 and the gear 502 changes, and the gear 502 will rotate. The rotation of the gear 502 will drive the two second racks 504 to change position, thereby pulling the pull rod 505, so that the two side clamping plates 506 move inward along the first slide groove 507 to complete the clamping and fixing of the side of the floor slab. At this time, the vertical and lateral degrees of freedom of the floor slab can be limited to prevent the floor slab from changing position during testing.

[0026] The movable frame mechanism 6 includes a movable frame groove 601 formed on the workbench 1. A first threaded rod 602 is rotatably connected to the workbench 1 within the movable frame groove 601. A second motor 603 is provided on the side of the workbench 1. The output shaft of the second motor 603 is coaxially and fixedly connected to the first threaded rod 602. The first threaded rod 602 is threadedly connected to the movable frame 604. The movable frame 604 is slidably connected to the workbench 1. Two second bearing rods 605 are fixedly connected to the movable frame 604. The two second bearing rods 605 are symmetrically arranged on the movable frame 604 and are on the same horizontal plane.

[0027] Specifically, when the second motor 603 is turned on, the output shaft of the second motor 603 rotates, which drives the first threaded rod 602 to rotate, causing the moving frame 604 to move along the moving frame groove 601.

[0028] The detection and adjustment mechanism 10 includes a first fixing plate 1001 and a second fixing plate 1002 fixed on the workbench 1. Two first fixing plates 1001 and two second fixing plates 1002 are provided. A second threaded rod 1003 is rotatably connected between the two first fixing plates 1001. A third motor 1004 is provided on the outer side of one of the first fixing plates 1001. The output shaft of the third motor 1004 and the second threaded rod 1003 are coaxially and fixedly connected. A limiting slide rod 1005 is fixedly connected between the two second fixing plates 1002. The second threaded rod 1003 is threadedly connected to a movable frame 1006, and the limiting slide rod 1005 passes through the movable frame 1006. It is slidably connected to the movable frame 1006. The movable frame 1006 is fixedly connected to the second hydraulic push rod 1007. The second hydraulic push rod 1007 is fixedly connected to the pressing frame 1008. The pressing frame 1008 passes through the movable frame 1006 and is slidably connected to the movable frame 1006. The pressing frame 1008 is fixedly connected to the pressing seat 1009. The pressing seat 1009 is equipped with a fourth motor 1010. The output shaft of the fourth motor 1010 is fixedly connected to the third threaded rod 1011. The third threaded rod 1011 is threadedly connected to the detection sensor 1012. The detection sensor 1012 and the pressing seat 1009 are slidably connected. The detection sensor 1012 and the pressing block 11 are connected.

[0029] Specifically, turning on the third motor 1004 can drive the second threaded rod 1003 to rotate, which in turn drives the moving frame 1006 to move along the axis of the limiting slide rod 1005, thereby causing the longitudinal position of the pressure block 11 to change. Turning on the fourth motor 1010 can drive the third threaded rod 1011 to rotate, causing the detection sensor 1012 to change laterally, thereby causing the lateral position of the pressure block 11 to change. Turning on the second hydraulic push rod 1007 can drive the pressure block 11 to feed, thereby realizing the strength detection of the floor slab.

[0030] Example 2, see below. Figures 1-3 In this embodiment of the invention, the elastic driven roller mechanism 7 includes a second lifting groove 701 opened on the side of the movable frame 604. There are two second lifting grooves 701, which are symmetrically arranged on the movable frame 604.

The second slider 703 and the movable frame 604 are slidably connected, and the second slider 703 is rotatably connected to the driven roller 704.

[0031] Specifically, the third spring 702 can push the second slider 703, which in turn pushes the driven roller 704, causing the driven roller 704 to contact the floor slab.

[0032] In the implementation of this invention, the floor slab to be tested is first placed on the fixed frame mechanism 2. The elastic drive roller mechanism 3 is activated to drive the floor slab to the designated position. The first feed pressure plate mechanism 4 is activated to drive the first linkage clamping mechanism 5, thereby fixing one end of the floor slab. If it is necessary to adjust the cantilever state of the floor slab, the moving frame mechanism 6 is activated to move the second feed pressure plate mechanism 8 and the second linkage clamping mechanism 9 to the designated position. The second feed pressure plate mechanism 8 is activated to drive the second linkage clamping mechanism 9, thereby clamping and fixing the floor slab. The detection adjustment mechanism 10 is then activated to move the pressure block 11 to the designated position, thereby realizing the detection of the floor slab's strength.

[0033] This invention, by setting up an elastic drive roller mechanism 3, can drive the floor slab placed on the fixed frame mechanism 2 to move. In conjunction with the moving frame mechanism 6, it can control the cantilever installation state of the floor slab, thereby simulating the actual floor slab installation. The first feed pressure plate mechanism 4 and the first linkage clamping mechanism 5 can clamp and fix one end of the floor slab of different sizes. The second feed pressure plate mechanism 8 and the second linkage clamping mechanism 9 can clamp and fix the other end of the floor slab of different sizes.
