Elevator bearing
Technical field
The present invention relates to elevator technology field, particularly relate to elevator bearing.
Background technology
Current elevator increases with skyscraper, popularize gradually, because elevator is manned equipment, its safe in operation is significant, for effectively alleviating impulsive force when elevator falls, in elevator, all can be embedded with buffer of elevator, due to the elevator bearing undercapacity of locating for buffer of elevator, the stress at installation position place such as too to concentrate at the reason, is easy to the inefficacy causing buffer of elevator, brings very large potential safety hazard to elevator.
Summary of the invention
The object of the present invention is to provide a kind of intensity high, stress is little, buffer of elevator positioning stablity failure-free elevator bearing.
For reaching this object, the present invention by the following technical solutions:
Elevator bearing, this elevator bearing comprises housing and is symmetricly set in the installation fixing position of both sides inside and outside described housing bottom surface, described installation fixing position comprises the frustum of a cone being convexly equipped in both sides inside and outside described housing bottom surface, be arranged at first cylinder at the top of the described frustum of a cone, and be arranged at second cylinder at described cylinder top, the described frustum of a cone, the through hole being provided with and installing for buffer of elevator is axially run through at described first cylinder and described second cylindrical middle part, and the surrounding of described installation fixing position is evenly distributed in reinforced rib, and the described reinforced rib of the left and right sides, bottom surface is symmetrical arranged.
Wherein, described installation fixing position is positioned at the middle part of described housing, and described housing is provided with eight housing walls be connected successively, and the junction of the madial wall of adjacent housings wall is provided with the screw fixed leg for fastened by screw.
Wherein, the lateral wall of described housing wall stretches out and is provided with stiffened edge, is provided with housing wall reinforced rib between the lateral wall of described stiffened edge and described housing wall.
Wherein, the lateral wall of the housing wall below this elevator bearing is provided with the feet be convenient to buffer of elevator and installed, and described feet is provided with mounting hole.
Wherein, the edge in the outside of described housing bottom surface is provided with positioning convex, and the middle part of described positioning convex is provided with knock hole.
Wherein, this elevator bearing adopts cast iron casting one-body molded.
Beneficial effect of the present invention: the present invention includes housing and be symmetricly set in the installation fixing position of both sides inside and outside described housing bottom surface, described installation fixing position comprises the frustum of a cone being convexly equipped in both sides inside and outside described housing bottom surface, be arranged at first cylinder at the top of the described frustum of a cone, and be arranged at second cylinder at described cylinder top, the described frustum of a cone, the through hole being provided with and installing for buffer of elevator is axially run through at described first cylinder and described second cylindrical middle part, and the surrounding of described installation fixing position is evenly distributed in reinforced rib, and the described reinforced rib of the left and right sides, bottom surface is symmetrical arranged.The installation fixing position of this structure design, is convenient to the installation of buffer of elevator, and positioning stablity is reliable, reduces the stress of installation fixing position surrounding housing bottom surface.

Fig. 1 is elevator bearing front of the present invention axonometric drawing.
Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1, this elevator bearing comprises housing and is symmetricly set in the installation fixing position of both sides inside and outside described housing bottom surface, described installation fixing position comprises the frustum of a cone 1 being convexly equipped in both sides inside and outside described housing bottom surface, be arranged at first cylinder 2 at the top of the described frustum of a cone 1, and be arranged at second cylinder 3 at described cylinder top, the described frustum of a cone 1, the through hole 4 being provided with and installing for buffer of elevator is axially run through at the middle part of described first cylinder 2 and described second cylinder 3, and the surrounding of described installation fixing position is evenly distributed in reinforced rib 5, and the described reinforced rib 5 of the left and right sides, bottom surface is symmetrical arranged.Preferably, the frustum of a cone 1, first cylinder and the second cylinder 3 adopt cast iron casting one-body molded obtained with housing, and through hole adopts secondary processing shaping.
Preferred further, described installation fixing position is positioned at the middle part of described housing, and described housing is provided with eight housing walls 6 be connected successively, and the junction of the madial wall of adjacent housings wall 6 is provided with the screw fixed leg 7 for fastened by screw.The design of this structure is not only conducive to the fastening of screw, is more conducive to the intensity strengthening housing wall.
Preferred further, the lateral wall of described housing wall 6 stretches out and is provided with stiffened edge 8, is provided with housing wall 6 reinforced rib between described stiffened edge 8 and the lateral wall of described housing wall 6.
Preferred further, the lateral wall of the housing wall 6 below this elevator bearing is provided with the feet 9 be convenient to buffer of elevator and installed, and described feet 9 is provided with mounting hole.
Preferred further, the edge in the outside of described housing bottom surface is provided with positioning convex, and the middle part of described positioning convex is provided with knock hole.The design of this structure, is convenient to location when elevator bearing level is installed, makes quick and easy for installation.
Adopt the elevator bearing of said structure design, because the through hole surrounding for lift-mounting energy disperser is provided with reinforcement structure, thus make positioning stablity reliable, and the stress of installation fixing position surrounding housing bottom surface.
Below know-why of the present invention is described in conjunction with specific embodiments.These describe just in order to explain principle of the present invention, and can not be interpreted as limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present invention, and these modes all will fall within protection scope of the present invention.
