Detailed Description
As shown in fig. 1 to 3, a multi-stiffness elevator guiding device is composed of a roller i 1, an upper spring assembly 2, a spring limit sleeve 3, a spring pre-tightening bolt 4, a lower spring assembly 5, a spring guiding shaft 6, a rocker arm 7, a guide shoe 8, a rocker arm shaft 9, a roller shaft 10, a roller ii 11, a roller iii 12, a middle stiffness spring 13, a low stiffness spring i 14, a low stiffness spring ii 15 and a high stiffness spring 16, wherein the roller i 1, the roller ii 11 and the roller iii 12 are arranged on the guide shoe, the roller i 1 is arranged in parallel with the roller iii 12, the roller ii 11 is arranged at the middle position of the roller i 1 and the roller iii 12 and is perpendicular to the roller i 1 and the roller iii 12, the roller is fixed on the rocker arm 7 through the axle center position of the roller shaft, one end of the roller shaft 10 is fixed by a step, the other end of the roller is fixed by an axle end retainer ring, and the roller can freely rotate around the roller shaft. The rocker arm shaft 9 passes through a through hole below the rocker arm 7 and is fixed on the guide shoe 8, wherein one end of the rocker arm shaft 9 is fixed by a step, and the other end is fixed by a shaft end retainer ring. The rocker arm 7 presses the roller wheel on the guide rail through the upper spring combination and the lower spring combination. The upper spring combination is composed of an outer middle stiffness spring 13 and a low stiffness spring I14 arranged in the upper spring combination, a step hole is formed in the rocker arm 7 and is opened according to the outer diameter of the spring, a first layer of step is formed according to the outer diameter of the middle stiffness spring 13 and is used for fixing one end of the middle stiffness spring 13, the other end of the first layer of step is limited by a spring limiting sleeve, a second layer of step is formed according to the outer diameter of the low stiffness spring and is used for fixing one end of the low stiffness spring, the other end of the second layer of step is limited by the spring limiting sleeve, a third layer of step is a through hole, penetrates through a screw rod which protrudes out of the guide shoe 8, the screw rod is integrally molded and cast on the guide shoe 8, and the screw rod penetrates through the low stiffness spring to play a role in guiding.
