Abstract
The utility model discloses a main shaft supporting structure of an adjustable elevator host machine, which comprises a host machine, a traction wheel, a supporting seat and a main shaft, wherein the traction wheel is erected between both sides of the supporting seat through the main shaft, the supporting seat comprises a fixed supporting seat and a movable supporting seat which is fixed on a base of the host machine through a set of positioning bolts, and adjusting shims are arranged between the movable supporting seat and the base of the host machine. The utility model can accurately adjust a main shaft of an elevator to effectively ensure the accuracy requirements of the main shaft, the traction wheel, etc. through adjusting the numbers of the positioning bolts and the adjusting shims between the movable supporting seat and the base of the host machine. Besides, the movable supporting seat on the outer side of the supporting structure can be disassembled, the utility model has simple installation and adjustment, and the requirements of maintaining operation such as replacing the traction wheel in the scene, etc., are ensured.
Description
Technical field
The utility model relates to a kind of main shaft supporting structure of adjustable elevator main, and particularly the permagnetic synchronous motor main frame adopts the main shaft supporting structure that two point supports.
Background technology
The main frame of traction elevator adopts the mode of traction sheave both sides support usually because of the requirement of its suspended weights and precision.Consider the mounting process of the parts such as main shaft, traction sheave of main frame, require its supporting construction on one side detachable usually, and require to guarantee the accuracy requirement of main frame traction sheave after its dismounting and the assembling.In addition, when needing to guarantee elevator main production efficiency, when being carried out field maintemance, guarantee, client's elevator can carry out charge and discharge operations.
Existing elevator main main shaft supporting structure, as shown in Figure 1, the supporting seat 3 at its main shaft two ends is processed to integrative-structure with the base 11 of main frame 1, and traction sheave 2 is set up on the supporting seat 3 of both sides by main shaft 4.But, because traction sheave 2 is in the mode of operation of heavy load for a long time, may cause main shaft 4 run-off the straights, further cause the vibration in the running process of elevator, and the wearing and tearing of motor internal etc., influence the normal operation of elevator device.The defective of existing supporting construction promptly is, can't adjust inclination that the main shaft of above-mentioned elevator main produces, skew etc. in time, easily, and the charge and discharge operations of this supporting construction is more loaded down with trivial details, is not easy to carry out work such as field maintemance, guarantee.
Summary of the invention
The purpose of this utility model is to provide a kind of conveniently assemble and disassemble, and has the elevator main main shaft supporting structure of tunable arrangement.
The technical scheme that the utility model adopted: a kind of main shaft supporting structure of adjustable elevator main, comprise main frame, traction sheave, supporting seat and main shaft, traction sheave is set up between the supported on both sides seat by main shaft, it is characterized in that, described supporting seat comprises fixed supporting seat and kinematic support seat, this kinematic support seat is fixed on the base of main frame by one group of dowel bolt, is provided with bearing cap shim between kinematic support seat and the main frame base.
Realize the adjustment of above-mentioned kinematic support seat on the main frame base for convenience, one group of dowel bolt is arranged at the base plate two ends of this kinematic support seat, and one of them dowel bolt passes the screw on the kinematic support seat base plate, terminate in the main frame base upper surface, in order to adjust the gap length between kinematic support seat and the main frame base; Another dowel bolt passes the screw on the kinematic support seat base plate, and is spirally connected with the base of main frame, in order to fixedly kinematic support seat and main frame base.
The beneficial effects of the utility model, (1) is by the adjustment dowel bolt, and the pad number between movable supporting plate and the main frame base, can realize the accurate adjustment to the elevator main main shaft, effectively guarantees the accuracy requirement of parts such as main shaft, traction sheave; (2) the kinematic support seat in its outside is detachable, and installation and debugging work are simple, guarantees to change at the scene the requirement of maintenance activities such as traction sheave.
Description of drawings
Fig. 1 is the main shaft supporting structure scheme drawing of existing elevator main;
Fig. 2 is the main shaft supporting structure scheme drawing of elevator main described in the utility model;
Fig. 3 is the lateral plan of structure shown in Figure 2.
The specific embodiment
Shown in Fig. 2,3, the utility model comprises main frame 1, traction sheave 2, supporting seat, main shaft 4, and one group of dowel bolt 51,52 and bearing cap shim 53, wherein, supporting seat comprises fixed supporting seat and kinematic support seat 3, this kinematic support seat 3 is fixed in by dowel bolt 51,52 on the base 11 of main frame, is provided with bearing cap shim 53 between kinematic support seat 3 and the main frame base 11.One end of main shaft 4 is connected with main frame, and the other end is fixing by kinematic support seat 3 and supporting seat loam cake 31, and traction sheave 2 is set up between the supported on both sides seat by main shaft 4.Described dowel bolt 51,52 is located at base plate 32 two ends of kinematic support seat 3, one of them dowel bolt 51 passes the screw on the kinematic support seat base plate 32, terminate in main frame base 11 upper surfaces, in order to adjust the gap length between kinematic support seat 3 and the main frame base 11; Another dowel bolt 52 passes the screw on the kinematic support seat base plate 32, and is spirally connected with the base 11 of main frame, in order to fixedly kinematic support seat 3 and main frame base 11.
Compare with the main shaft supporting structure of existing elevator main shown in Figure 1, the outside of the present utility model kinematic support seat 3 is detachable, and the precision that can regulate main shafts 4 by dowel bolt 51,52 on the kinematic support seat 3 and bearing cap shim 53.When main shaft or traction sheave because of bearing a heavy burden or during the other factors run-off the straight, can adjust by the following method: at first, unclamp dowel bolt 52, and, regulate the gap length of kinematic support seat 3 and main frame base 11 by adjusting dowel bolt 51 according to the main shaft inclined degree; Then, according to above-mentioned main shaft inclined degree, increase or the bearing cap shim 53 between supporting seat 3 and the main frame base 11 of taking in sail (selecting as required, the pad of suitable thickness) number; At last, screwed in place bolt 51,52,3 stable being fixed on the main frame base 11 of kinematic support seat make main shaft 4 maintenance levels, promptly reach its accuracy requirement.
