Description
Technical field
The utility model relates to a kind of elevator traction system, belongs to elevator technology field.
Background technology
The pulley of existing elevator traction system adopts a plurality of pulleys to use as one group of pulley conventionally, and such pulley is stable not.Also having a kind of pulley is integral type pulley, produces the groove of a plurality of placement steel cables as one group of pulley on main shaft, and shortcoming is after a pulley groove serious wear, need to all change.And the pulley of a corresponding a kind of specification of elevator size model needs, increased number of fitting parts and cost.
Summary of the invention
The purpose of this utility model is: a kind of elevator traction system is provided, and its hauling block adopts one-piece construction, more stable, and the distance between can adjustable pulley groove, adapt to different elevators, after pulley groove serious wear, can also change separately, reduced maintenance cost.
The technical solution of the utility model: elevator traction system, include traction electric machine, traction electric machine connects lifting rope by hauling block, one end of lifting rope is fixed on the first joint, then through after the car pulley of car, be wrapped on hauling block, again through after the counterweight pulley of counterweight, the other end of lifting rope is fixed on the second joint, described hauling block structure comprises main shaft, at main shaft two ends, be provided with the fixed muffle of screw thread and screw thread fit, main shaft is provided with at least 1 pulley sleeve, in the middle of pulley sleeve, be provided with groove, between pulley sleeve, be provided with abutment sleeve, on main shaft, be provided with dowel hole, pulley sleeve is provided with locating dowel pin.
Above-mentioned elevator traction system, the groove in the middle of described pulley sleeve is provided with wearing layer.
The beneficial effects of the utility model: hauling block of the present utility model is installed pulley sleeve and abutment sleeve on main shaft, by the different size of regioselective sleeve, spacing that can adjustable pulley sleeve, to mate different elevators.After pulley serious wear, only need to take the fixed muffle at main shaft two ends apart, replaceable pulley sleeve cylinder, changes conveniently, has reduced maintenance cost.Hauling block Stability Analysis of Structures of the present utility model, easy for installation, there is good financial cost.

The specific embodiment
Embodiment of the present utility model: elevator traction system, as illustrated in fig. 1 and 2, include traction electric machine 9, traction electric machine 9 connects lifting rope 12 by hauling block 10, one end of lifting rope 12 is fixed on the first joint 17, then through after the car pulley 16 of car 11, be wrapped on hauling block 10, again through after the counterweight pulley 13 of counterweight 14, the other end of lifting rope 12 is fixed on the second joint 15, described hauling block 10 structures comprise main shaft 1, at main shaft 1 two ends, produce screw thread, fixed muffle 2 by screw thread fit is fixed, on main shaft 1, be inserted at least 1 pulley sleeve 4, pulley sleeve 4 intermediate fabrication go out groove 5, between pulley sleeve 4, be provided with abutment sleeve 3, width by regioselective sleeve 3 carrys out the spacing between adjustable pulley sleeve 4, to coordinate different elevator requirements.
As shown in Figures 3 and 4, produce dowel hole 7 on main shaft 1, produce locating dowel pin 8 on pulley sleeve 4, by locating dowel pin 8, fix pulley sleeve 4, locating dowel pin 8 can be selected one or more.
On groove 5 in the middle of pulley sleeve 4, wearing layer 6 is set, to improve the resistance to abrasion of groove 5.
During installation, by screw thread, the fixed muffle of main shaft 1 one end 2 is fixing, then installation requirement, successively through pulley sleeve 4 and abutment sleeve 3, is finally tightened the fixed muffle 2 of main shaft 1 other end fixing.After pulley sleeve 4 serious wear, only need to take the fixed muffle 2 at main shaft 1 two ends apart, replaceable pulley sleeve cylinder 4, has reduced replacement cost.
