Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1-2, a kind of damping device for elevator car of the present invention, comprise hauling hope 1, car frame 4, crosshead sheave 9, guide rail 11 and car cab 12, crosshead sheave 9 is connected with the rotating shaft of motor by hauling hope 1, crosshead sheave 9 and car cab 12 are all fixed in car frame 4, and four guide rails 11 are separately positioned on the both sides of car frame 4; What it also comprised that several and guide rail 11 match mutually leads boots assembly 3, leading boots assembly 3 is separately positioned on four angles of car frame 4 upper and lower surfaces, under car frame 4 upper surfaces, be provided with vibration-absorbing mounting 6, vibration-absorbing mounting 6 is fixedly connected by rubber damper 5 and car frame 4 upper surfaces, the top wheel shaft 8 of crosshead sheave 9 is connected with vibration-absorbing mounting 6 by U-shaped anchor ear 7, and the lower surface of described car cab 12 is fixedly connected by rubber damper 5 and car frame 4 lower surfaces.
Further, the described boots assembly 3 of leading includes base plate 3-1, base plate 3-1 is fixedly installed on the surface of car frame 4, base plate 3-1 is fixedly installed three and leads boots wheel 3-3, lead boots wheel 3-3 for three and surround the cavity matching mutually with guide rail 11, guide rail 11 is nested in this cavity, the both sides of leading boots wheel 3-3 are provided with fixed block 3-2, fixed block 3-2 one end is fixedly installed on base plate 3-1, the boots wheel shaft 3-4 that leads boots wheel 3-3 is connected with the fixed block 3-2 the other end by bearing 3-6, lead the interior also nested shock absorbing sleeve 3-5 that is provided with of boots wheel 3-3, boots wheel shaft 3-4 is closely nested in the endoporus of shock absorbing sleeve 3-5.
