[0025] like Figure 1-4As shown, a seismic test device includes a bracket 1, a sliding mounting plate 3 slidably arranged on the upper section of the bracket 1, and two clamp fixing mechanisms 4 located on the surface of the bracket 1, a cylinder 2 is fixed on the bracket 1, the sliding mounting plate 3 is fixed to the cylinder 2, the clamp fixing mechanism 4 includes a pressing plate 41, a hollow rod 42, a vertical rod 43 and a storage mechanism, there are several pressing plates 41 and at least one group, each group is evenly distributed around the circumference of the axis of the hollow rod 42, the hollow rod 42 is arranged perpendicular to the axis of the hollow rod 42 and one end is fixed to the pressing plate 41, the other end passes through the wall of the hollow rod 42 and extends to the inside and is fixed to the storage mechanism, the storage mechanism is used to drive the vertical rod 43 to move, and the clamp fixing mechanism 4 is respectively fixed to the distance adjustment mechanism 5.
[0026] In this embodiment, when the seismic support needs to be tested, the clamp is first fixed to the clamp fixing mechanism 4, and then the seismic connecting part is fixed to the sliding mounting plate 3. The clamp is first placed in the clamp fixing mechanism 4, and then the vertical rod 43 is pushed by the storage mechanism to move along the through groove of the hollow rod 42 until the vertical rod 43 fits the clamp. At this time, the clamp is fixed, so the clamp can be fixed like a pipe and then tested, thereby solving the problem of inconvenient clamp fixing affecting the test.
[0027] Specifically, the storage mechanism includes a connecting rod 44, a first screw sleeve 45, a one-way screw 46 and a first manual knob 47. The one-way screw 46 is coaxially fixed to the hollow rod 42 and one end is rotatably connected to the inner wall of the hollow rod 42, and the other end passes through the hollow rod 42 and extends to be fixed to the first manual knob 47. The first screw sleeve 45 is threadedly connected to the one-way screw 46. One end of the connecting rod 44 is movably connected to the first screw sleeve 45, and the other end is movably connected to the vertical rod 43.
[0028] In this embodiment, the one-way screw 46 can be driven to rotate by rotating the first manual knob 47. As the one-way screw 46 rotates, the first screw sleeve 45 will move axially along the one-way screw 46. Therefore, the connecting rod 44 will push the vertical rod 43 to continuously extend outward or retract, thereby adjusting the distance between the pressure plate 41 and the hollow rod 42 and adapting to different components.
[0029] Specifically, there are two first screw sleeves 45 .
[0030] In this embodiment, two first screw sleeves 45 are provided, so as the number of the vertical rods 43 increases, the stability of the fixing of the pressing plate 41 is increased.
[0031] Specifically, the pitch adjusting mechanism 5 includes an accommodating chamber 51, a double-headed screw 52, a second screw sleeve 53, a fixing rod 54 and a rotating component. The lower part of the bracket 1 is provided with an accommodating chamber 51, the double-headed screw 52 is located in the accommodating chamber 51 and both ends are rotatably connected to the wall of the accommodating chamber 51 respectively. There are two second screw sleeves 53 and they are relatively arranged on the double-headed screw 52. One end of the fixing rod 54 is fixed to the second screw sleeve 53, and the other end passes through the accommodating chamber 51 and extends to be fixed to the corresponding clamp fixing mechanism 4. The rotating component is used to drive the double-headed screw 52 to rotate. The rotating component includes a worm gear 55, a worm 56 and a second manual knob 57. The worm gear 55 is coaxially fixed with the double-headed screw 52, the worm 56 is meshed with the worm gear 55 and one end passes through the accommodating chamber 51 and extends to the outside and is fixed to the second manual knob 57.
[0032] In this embodiment, the worm wheel 55 meshing with the worm 56 can be rotated by rotating the second manual knob 57. Since the worm wheel 55 and the double-headed screw 52 are coaxially fixed, the distance between the second screw sleeve 53 can be adjusted. The second screw sleeve 53 and the clamp fixing mechanism 4 are fixed by a fixing rod 54. Therefore, the rotation of the second manual knob 57 can adjust the distance between the clamp fixing mechanism 4 so that testing can be performed according to different seismic brackets.
[0033] In summary: when it is necessary to test the seismic support, first fix the clamp on the clamp fixing mechanism 4, and then fix the seismic connecting part on the sliding mounting plate 3. The clamp is first placed in the clamp fixing mechanism 4, and then the vertical rod 43 is pushed through the storage mechanism to move along the through groove of the hollow rod 42 until the vertical rod 43 fits the clamp. At this time, the clamp is fixed, so the clamp can be fixed like a pipe and then tested, thereby solving the problem of inconvenient clamp fixing affecting the test.
