According to the utility model, a first layer of vibration reduction structure is formed by independent distribution of a first vibration reduction structure 5, a second vibration reduction structure 6 and a third vibration reduction structure 7 in each direction; the second layer of vibration reduction structure formed by swinging the first connecting rod vibration reduction mechanism 2, the second connecting rod vibration reduction mechanism 3 and the third connecting rod vibration reduction mechanism 4 absorbs impact energy caused by large deformation of the guide rail, and the double-layer vibration reduction structure is adopted to improve the vibration isolation efficiency of the sliding guide shoe, so that the adaptability of the guide shoe to high elevator speed and large deformation of the guide rail is improved.
Referring to fig. 2 and 5, in this embodiment, in particular, each of the first link damping mechanism 2, the second link damping mechanism 3, and the third link damping mechanism 4 includes a damping link 100, a rotating shaft 101, a damping shaft 102, a fixed shaft 103, and a first-stage elastic element 104; the vibration damping connecting rod 100 is arranged on the base 1 in a swinging mode through a rotating shaft 101; the first damping structure 5 is mounted on the damping link 100 via a damping shaft 102 in a luffing manner; the first stage elastic member 104 is in contact connection with the damper link 100 through a fixing shaft 103 and a spring washer 105.
Referring to fig. 2 and 4 and fig. 9 and 10, in the embodiment, in particular, each of the first damping structure 5, the second damping structure 6 and the third damping structure 7 includes a damping shoe arm 200, a shoe liner 201 and a second-stage elastic element 203; said shock shoe arm 200 is pitch-roll mounted to said shock link 100 via spacer sleeve 204 and said shock shaft 102; the shoe liner 201 is mounted to the vibration damping shoe arm 200 via the second stage elastic member 203. It should be noted that, when the present invention is used, an exciting force from the guide rail first acts on the shoe guide 201, and since the second-stage elastic element 203 is placed below the shoe guide 201, the second-stage elastic element 203 is compressed, so as to absorb and dissipate a part of the impact energy of the guide rail. The damping shoe arm 200 is the primary damping mechanism of the sliding guide shoe of the present invention and is capable of pitching about the damping shaft 102 in addition to translating along the normal of the guide rail contact surface.

It should be noted that one end of the first stage elastic member 104 is connected to the damper link 100, and the other end of the first stage elastic member 104 is fixed to the fixed shaft 103 through a spring washer 105 and a nut. Therefore, the vibration link 100 can be swung about the rotary shaft 101 by the exciting force from the vibration shoe arm 200, and the first-stage elastic element 104 is compressed in the axial direction. Due to the presence of the first stage elastic element 104, the impact energy of the linear damping link 100 is converted into potential energy of the first stage elastic element 104, and the impact of the guide rail is absorbed. The in-line damping link 100 is the second stage damping mechanism for the sliding guide shoe of the present invention. It should be noted that the compression stroke of the first stage elastic element 104 and thus the compression force of the shoe guide 201 on the guide rail can be adjusted by the nut of the spring washer 105, so as to improve the anti-vibration performance of the guide shoe.
Referring to fig. 3 and 4 and fig. 8, in the embodiment, specifically, the damping connecting rod 100 has an L-shaped structure; the first stage resilient element 104 is longitudinally mounted to the damper linkage 100.

Therefore, the vibration link 100 can be swung about the rotary shaft 101 by the exciting force from the vibration shoe arm 200, and the first-stage elastic element 104 is compressed in the axial direction. Due to the existence of the first stage elastic element 104, the impact energy of the damping link 100 with the L-shaped structure is changed into the potential energy of the first stage elastic element 104, and the impact of the guide rail is absorbed. The damping link 100 of the L-shaped structure is a second stage damping mechanism of the sliding guide shoe of the present invention. It should be noted that the compression stroke of the first stage elastic element 104 and thus the compression force of the shoe guide 201 on the guide rail can be adjusted by the nut of the spring washer 105, so as to improve the anti-vibration performance of the guide shoe.
Referring to fig. 1 and 2 and fig. 9, in the embodiment, the damping shoe arm 200 has a T-shaped structure. The damping shoe arm 200 may be configured in other shapes according to different applications, and is not limited to the T-shaped configuration.

Referring to fig. 3 and 6, in the embodiment, in particular, the first vibration damping structure 5, the second vibration damping structure 6 and the third vibration damping structure 7 are arranged in a shape of a Chinese character 'ao' with three separated surfaces. It should be noted that, after the first vibration damping structure 5, the second vibration damping structure 6 and the third vibration damping structure 7 are independent in each direction, the sliding guide shoe can independently adjust the compression force in each direction, and the vibration exciting and isolating efficiency and adaptability of the guide shoe to the guide rail are improved; the elevator uses the sliding guide shoe at the lifting speed of 2.5m/s and below.

Specifically, in this embodiment, the first stage elastic element 104 and the second stage elastic element are both one of a spring and a rubber. It should be noted that the first-stage elastic element 104 and the second-stage elastic element may also be elastomers such as microcellular elastomers; through setting up first order elastic element 104 and second level elastic element can effectively absorb the impact energy of dissipation guide rail, further improve the vibration isolation rate of elevator slip guide shoe, effectively reduced the interior vibration of sedan-chair.
