[0022] like Figure 1-4 As shown, the utility model proposes an amplified displacement friction damper device, including a steel frame column 1, a sliding device 2, a force transmission rod 3, an L-shaped connecting rod 4, a steel frame beam 5, a T-shaped steel plate 6, a friction plate 7 and a dustproof device 8, the sliding device 2 is arranged on the steel frame column 1, one end of the force transmission rod 3 is fixed on the sliding device 2, and the other end is rotatably connected to one end of two groups of L-shaped connecting rods 4, the steel frame beam 5 is fixed on the sliding device 2, the L-shaped connecting rod 4 is rotatably connected to both sides of the steel frame beam 5 through a sleeve 19 penetrating the steel frame beam 5, the T-shaped steel plate 6 is fixed on the external wall, the friction plate 7 is arranged between the L-shaped connecting rod 4 and the T-shaped steel plate 6, and the dustproof device 8 is arranged between the steel frame column 1 and the external wall.
[0023] As the instruction manual Figure 2 As shown, in order to facilitate the replacement of the friction plate 7, the sliding device 2 includes a fixed plate 19, a fixed plate 10, a motor 11, a screw 12, a slide 13 and a threaded slider 14. The fixed plate 19 and the fixed plate 10 are fixed on the steel frame column 1, the motor 11 is fixed on the upper side of the fixed plate 19 and the output shaft penetrates the fixed plate 19, one end of the screw 12 is fixed to the output shaft of the motor 11 and the other end is rotatably arranged on the fixed plate 10, the slide 13 is opened on the steel frame column 1, one side of the threaded slider 14 is threadedly connected to the screw 12 and the other side is slidably arranged on the slide 13. In order to prevent the material from affecting the device, the threaded slider 14 is made of steel.
[0024] As the instruction manual Figure 3As shown, in order to prevent dust from affecting the device, the dustproof device 8 includes a fixed plate three 15, a telescopic rod 16, a dust cover 17 and a dustproof box 18. One end of the fixed plate three 15 is fixed to the steel frame column 1 and the other end is fixed to the external wall. The telescopic rod 16 is fixed to the fixed plate three 15, the dust cover 17 is fixed to the upper side of the threaded slider 14, and the dustproof box 18 is fixed to the telescopic rod 16. In order to make the dust cover 17 more dustproof, one end of the dust cover 17 is set against the external wall.
[0025] In order to make the dustproof box 18 better fit the friction damper and be more dust-proof without affecting the operation of the friction damper, the dustproof box 18 is provided with four sides, the bottom side is fixed on the telescopic rod 16, the side close to the steel frame column 1 is half-sided, which is sealed against the threaded slider 14, and the upper parts of the two sides away from the steel frame column 1 and the external wall are sealed against the dustproof cover 17.

This operation is simple and quick, so that people who do not understand the device can also quickly and conveniently replace the friction plate 7 to prevent problems with the device, saving manpower and material resources. The above is the entire use process of an amplified displacement friction damper device.
