Abstract
The utility model relates to elevator technology field, especially a kind of elevator traction machine encoder protective device；Including the land for compressing bearing and the flange for being connect with electric machine stand, annular convex platform is additionally provided on the flange, the cavity for accommodating rotary encoder is formed in the middle part of the annular convex platform, the annular convex platform periphery is communicated with two connecting tubes, the periphery of the annular convex platform is arranged with arc shield, the connecting tube is pierced by outside arc shield, the effect of connecting tube is easy for lead, since the gap between connecting tube and line is narrow when use, dust is difficult to enter, and the annular convex platform front end is equipped with cover board by screw；Protective capacities is outstanding, and arc shield surface is round and smooth, and the foreign matter that elevator is fallen is not easy to pound out big deformation on its surface；Arc shield has the function of absorbing impact force by self-deformation, to reduce the annular convex platform possibility that deformation occurs.
Description
Technical field
The utility model relates to elevator technology field, especially a kind of elevator traction machine encoder protective device.
Background technique
The encoder of elevator is easy the wound of invasion and the various impacts by dust due to being directly installed on outside shaft end
Evil.It is improved in the industry, such as Chinese patent discloses a kind of installation safeguard structure of motor rotary encoder, including motor
Base is equipped with bearing in the bearing hole of the electric machine stand, is also connected on the electric machine stand for fixing the bearing
Bearing (ball) cover, the bearing (ball) cover includes the land for compressing the bearing and the method for connecting with the electric machine stand
Orchid is additionally provided with annular convex platform on the flange, the cavity for accommodating rotary encoder, institute is formed in the middle part of the annular convex platform
State the fairlead for being additionally provided on the side wall of annular convex platform and passing through convenient for conducting wire.By being improved to bearing (ball) cover, in bearing end
The annular convex platform added for installing rotary encoder is covered, rotary encoder is mountable in the cavity of annular convex platform, thus
Rotary encoder can be protected, avoid rotary encoder receive collision, impact damage；On the side wall of annular convex platform also
Equipped with fairlead in order to which conducting wire passes through, convenient for the installation of rotary encoder.
Above-mentioned technical proposal has two: 1) being equipped with fairlead, be used for lead and observation, the coding of well known elevator
It should entirely be observed in device maintenance repair, and only can not check that in addition the hole is also easy to it by fairlead
Into dust；2) above scheme is protected rotary encoder using annular convex platform, and specifically it is similar with a metallic sheath
Rotary encoder is entangled, can no doubt play protection and dustproof effect under normal circumstances, but once has hard object to be caught in fairlead,
Annular convex platform will constantly scrape the rotary encoder of damage rotation just at the sander of rotary encoder, similarly, when impacting
Annular convex platform is caused also can constantly to scrape damage rotary encoder when being recessed inwardly.
Summary of the invention
In view of the deficiencies of the prior art, the utility model provides a kind of protection effect and dust-proof effect more preferably and easy access
Personnel check the protective device of encoder.
The technical solution of the utility model are as follows:
A kind of elevator traction machine encoder protective device, including the land for compressing bearing and for connecting with electric machine stand
The flange connect is additionally provided with annular convex platform on the flange, is formed in the middle part of the annular convex platform for accommodating rotary encoder
Cavity, it is characterised in that: the annular convex platform periphery is communicated with two connecting tubes, and the periphery of the annular convex platform is arranged with arc
Shield, the connecting tube are pierced by outside arc shield, and the effect of connecting tube is easy for lead, due between connecting tube and line when use
Gap it is narrow, dust is difficult to enter, and the annular convex platform front end is equipped with cover board by screw, for sealing device.
Further, the arc shield material is galvanized iron, it is not easy to be got rusty, reflecting rate is high, convenient for sending out in elevator
It is existing, it is easy deformation by hitting, is easy to absorb impact force.
Further, asbestos are filled in the arc shield, it is heat-insulated, it can absorb and hits.
Further, the connecting tube uses plastic conduit, and the hardness and toughness of plastic tube are far smaller than metal and are made
Annular convex platform, can have the function that cushion impact forces by the breakage of itself when plastic tube is impacted.
Further, the flange lateral wall is welded with cable wire, and the cable end is welded with a nut, by spiral shell when use
Mother is fixed by screws on the fixed structure of motor, and the benefit of the structure is: compiling when service personnel needs for the present apparatus to be detached from
When code device, allowed after disassembly it play can, without hand-held, solution releases the detection that both hands carry out indices.
The utility model has the following beneficial effects: protective capacities is outstanding, arc shield surface is round and smooth, the foreign matter that elevator is fallen
It is not easy to pound out big deformation on its surface；Arc shield has the function of absorbing impact force by self-deformation, to reduce
The annular convex platform possibility that deformation occurs.

Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing:
As shown in Figure 1, a kind of elevator traction machine encoder protective device, including the land 1 for compressing bearing and is used for
The flange 2 connecting with electric machine stand is additionally provided with annular convex platform 3 on the flange 2, is formed with and is used in the middle part of the annular convex platform 3
The cavity of rotary encoder is accommodated, 3 periphery of annular convex platform is communicated with two connecting tubes 7, the periphery set of the annular convex platform 3
Equipped with arc shield 6, the connecting tube 7 is pierced by outside arc shield 6, and 3 front end of annular convex platform is equipped with cover board by screw 5
4。
6 material of arc shield is galvanized iron.
Asbestos are filled in the arc shield 6.
The connecting tube 7 uses plastic conduit.
2 lateral wall of flange is welded with cable wire 8, and 8 end of cable wire is welded with a nut 9.
The description of the embodiments and the specification only illustrate the principle of the present utility model and most preferred embodiment, is not taking off
Under the premise of from the spirit and scope of the utility model, the utility model also has various changes and improvements, these changes and improvements
It falls within the scope of the claimed invention.
