Abstract
The utility model discloses a kind of elevator pulley, it is characterized in that: include main shaft (1), be provided with the fixed muffle (2) of screw thread and screw thread fit at main shaft (1) two ends, main shaft (1) is provided with at least 1 pulley sleeve (4), in the middle of pulley sleeve (4), be provided with groove (5), between pulley sleeve (4), be provided with abutment sleeve (3), on main shaft (1), be provided with dowel hole (7), pulley sleeve (4) is provided with locating dowel pin (8).The utility model is installed pulley sleeve and abutment sleeve on main shaft, and by the different size of regioselective sleeve, spacing that can adjustable pulley sleeve, to mate different elevators.When after pulley serious wear, only need to take the fixed muffle at main shaft two ends apart, i.e. replaceable pulley sleeve cylinder, it is convenient to change, and has reduced maintenance cost.
Description
Technical field
The utility model relates to a kind of elevator pulley, belongs to elevator parts technical field.
Background technology
Existing elevator traction pulley adopts multiple 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 multiple placement steel cables as one group of pulley on main shaft, and shortcoming is when 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, increase number of fitting parts and cost.
Summary of the invention
The purpose of this utility model is: a kind of elevator pulley is provided, adopts one-piece construction, and more stable, and 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 pulley, include main shaft, be provided with the fixed muffle of screw thread and screw thread fit at main shaft two ends, 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, be provided with dowel hole on main shaft, pulley sleeve is provided with locating dowel pin.
Above-mentioned elevator pulley, the groove in the middle of described pulley sleeve is provided with wearing layer.
The beneficial effects of the utility model: the 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.When after pulley serious wear, only need to take the fixed muffle at main shaft two ends apart, i.e. replaceable pulley sleeve cylinder, it is convenient to change, and has reduced maintenance cost.The utility model Stability Analysis of Structures, easy for installation, there is good financial cost.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is lateral plan of the present utility model;
Accompanying drawing 3 is the structural representation of the utility model pulley sleeve.
Reference numeral: 1-main shaft, 2-fixed muffle, 3-abutment sleeve, 4-pulley sleeve, 5-groove, 6-wearing layer, 7-dowel hole, 8-locating dowel pin.
Detailed description of the invention
Embodiment of the present utility model: elevator pulley, as shown in Figure 1, make main shaft 1, produce screw thread at main shaft 1 two ends, be fixed by the fixed muffle 2 of screw thread fit, 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, carry out the spacing between adjustable pulley sleeve 4 by the width of regioselective sleeve 3, to coordinate different elevator requirements.
As shown in Figures 2 and 3, produce dowel hole 7 on main shaft 1, produce locating dowel pin 8 on pulley sleeve 4, fix pulley sleeve 4 by locating dowel pin 8, 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.
When installation, by screw thread, by fixing the fixed muffle of main shaft 1 one end 2, 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.When 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.
