Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1-2, a kind of damping device for elevator car described in the utility model, 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; It also comprises 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.
