The lifting mechanism 3 is arranged in the case 2, and the lifting mechanism 3 is used for adjusting the height of the base 1. The lifting mechanism 3 includes a lifter 31, a support rod 32, a sprocket seat 33, a sprocket 34, and a chain 35. The lifting member 31 may be an oil cylinder, a cylinder body of the oil cylinder is fixedly mounted at the bottom of the case 2, a support rod 32 is mounted at the top end of a piston rod of the oil cylinder, a chain wheel seat 33 is mounted on the support rod 32, the chain wheel seat 33 is rotatably connected with a chain wheel 34 through a pin shaft, one end of a chain 35 is mounted at the bottom of the case 2, the other end of the chain 35 is connected with a guide rail 11 mounted on the base 1 by winding the chain wheel 34, and the guide rail 11 is vertically and slidably matched with a guide elongated slot 21 formed in the side wall of the case 2.
When the lifter 31 in the lifting mechanism 3 is lifted, the lifter 31 lifts the support rod 32, and the support rod 32 lifts the sprocket 34, so that the chain 35 pulls the base 1 to be lifted. When the lifting piece 31 in the lifting mechanism 3 is lowered, the lifting piece 31 drives the bearing rod 32 to be lowered, the bearing rod 32 drives the chain wheel 34 to be lowered, and the base 1 is lowered under the action of self weight. Thereby realizing the height adjustment of the base 1 by the lifting mechanism 3.
The lower end face of the base 1 is provided with a clamping mechanism 4 for clamping the vibration damping pad 5, and the clamping mechanism 4 comprises a fixed rod 41, a movable rod 42, an adjusting rod 43, a linkage rod 44, a supporting block 45 and a screw rod 46.
Two fixed rods 41 are installed on the lower end surface of the base 1, two movable rods 42 are arranged between the two fixed rods 41, a dovetail long groove 12 is arranged on the lower end surface of the base 1, a sliding block 421 is installed on each movable rod 42, the sliding block 421 is in sliding fit with the dovetail long groove 12, and when the movable rods 42 slide in the direction close to the fixed rods 41 or far away from the fixed rods 41, the sliding block 421 can slide in the dovetail long groove 12. When the movable rod 42 approaches the fixed rod 41, the movable rod 42 and the fixed rod 41 can clamp the damping pad 5 together; when the movable lever 42 is away from the fixed lever 41, the movable lever 42 and the fixed lever 41 can release the clamping of the damper pad 5.
Two adjusting rods 43 are arranged between the two movable rods 42, one end of one adjusting rod 43 is rotatably connected with one movable rod 42 through a pin shaft, one ends of the two adjusting rods 43 far away from the movable rods 42 are rotatably connected with the linkage rod 44 through pin shafts, the linkage rod 44 is provided with a rotating hole (not shown in the figure), one end of the screw rod 46 is rotatably matched with the rotating hole, two clamping rings 461 used for clamping the linkage rod 44 are installed on the screw rod 46, and the arrangement of the clamping rings 461 can prevent the screw rod 46 from axially moving along the rotating hole in the rotating hole.
