Abstract
The utility model provides a protection device of speed reducer encoder is raised to blast furnace master file, belongs to blast furnace material loading system device technical field for prevent that the encoder from damaging. Its technical scheme is: two ring flanges of flange are connected with encoder protective sheath, reducer output axle protective sheath respectively, the circumference equipartition flange connecting hole of two ring flanges of flange, and connecting bolt passes flange connecting hole and is connected two ring flanges, installation damper unit spare in the clearance of two ring flanges, damper unit spare is polyurethane pad or damping spring. The utility model discloses simple structure, shock attenuation are respond well, and damper unit spare can form corresponding buffering between encoder protective sheath, reducer output axle protective sheath, reduce the hoist unit and stop the vibration to the harmful effects that encoder connecting device led to the fact, and avoid encoder bolt looseness to take place the output shaft fracture even and the encoder that leads to the fact damages, prevent that the blast furnace is compelled to carry out pulling the wind or damping down operation because of the encoder trouble makes, guarantee the continuous production of blast furnace.
Description
Technical field
The utility model is related to a kind of device of encoder of protection on blast furnace master winch reductor shaft coupling, category
In Research for Feeding Raw Materials System equipment technical field.
Background technology
The 1000m of steel industry3Following blast furnace roof feeding system typically adopts truck feeding, its kind of drive to be electricity
Machine-reductor-reel-truck, by the encoder to count in the master winch reductor complete the truck speed of service determine,
Stroke is determined, and is done Dynamic comparison with mair motor speed measure feedback signal and is mutually monitored, and realizes that skip position signal off-axis is protected, together
When compared by encoder to count realize limit parking, the protection of high low speed, anti-back skating protection, ultralimit protection.Therefore, encoder
Stable operation it is most important to whole feeding system.In production scene, encoder is bolted installation on the protective sleeve,
Encoder protective case is connected with speed reducer output shaft protective case by shaft coupling.In actual moving process, elevator unit is stopping
Che Shi（Between reductor and rope roll）Produce transient vibration larger, can cause encoder bolt looseness that output axle fracture even occurs
And cause encoder to damage, and normally producing to blast furnace and make a big impact, blast furnace is forced checking or damping down operation, is unfavorable for blast furnace
Continuous production low cost movement, or even affect iron and steel output balance.Therefore, main winch is overcome to produce larger vibration when stopping
Phenomenon is damaged encoder, and normally operation is very necessary for protection encoder.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of protection dress of blast furnace master winch reductor encoder
Put, this protection device can play the cushioning effect of high reliability, reduce the damage of encoder, reduce because encoder fault is made
Into blast furnace checking or damping down accident.
Solving the technical scheme of above-mentioned technical problem is：
A kind of protection device of blast furnace master winch reductor encoder, it includes adpting flange, connecting bolt, damping portion
Part, two ring flanges of adpting flange are connected respectively with encoder protective case, speed reducer output shaft protective case, adpting flange
The circumference uniform distribution flange connecting hole of two ring flanges, connecting bolt is connected on two ring flanges through flange connecting hole, two
There is gap between individual ring flange, damping part is installed in the gap of two ring flanges.
The protection device of above-mentioned blast furnace master winch reductor encoder, the damping portion installed in described two flange dish gaps
Part is urethane pad, and urethane pad is circle, and the diameter of urethane pad matches with the diameter of ring flange, the circumference of urethane pad
There is the circular hole that connecting bolt is passed through, the thickness of urethane pad is 10-20mm.
The protection device of above-mentioned blast furnace master winch reductor encoder, the damping portion installed in described two flange dish gaps
Part is damping spring, and quantity and the connecting bolt of damping spring match, and damping spring is set on each connecting bolt.
The beneficial effects of the utility model are：
The utility model is connected to encoder protective case, speed reducer output shaft protective case using adpting flange, at two
Gap is reserved between ring flange, damping part is installed in gap, damping part is urethane pad or damping spring.This practicality is new
Type simple structure, damping effect are good, and damping part can be formed between encoder protective case, speed reducer output shaft protective case
Corresponding buffering, reduces the harmful effect that elevator unit rumble is caused to encoder connecting device, it is to avoid encoder bolt
Loosen the encoder for even output axle fracture occurring and causing to damage, prevent because encoder fault make blast furnace be forced to carry out checking or
Damping down is operated, it is ensured that the continuous production of blast furnace, reduces production cost.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Mark in figure as follows：Reel 1, motor 2, reductor 3, speed reducer output shaft protective case 4, encoder protective case 5, company

The circumference uniform distribution flange connecting hole of blue disk, connecting bolt 7 is connected on two ring flanges through flange connecting hole, in two flanges
There is gap between disk, damping part 8 is installed in the gap of two ring flanges.
Show in figure, a kind of damping part 8 is urethane pad, the advantage of urethane pad is to make simple, installs replacing side
Just, limit without Special use and require, can periodically be changed.Suitable for the master winch feeding system of general medium and small blast furnace.
The urethane pad that the utility model is installed is circle, and the diameter of urethane pad matches with the diameter of ring flange, urethane pad
Circumference has the circular hole that connecting bolt 7 is passed through, and the thickness of urethane pad is 10-20mm, and user can be selected as needed.
Show in figure, another kind of damping part 8 is damping spring, damping spring is traditional damping element, damping spring
Soft durometer and elasticity wide range, the selectivity for using is very big, can according to actual needs select most suitable damping bullet
Spring.During installation, damping spring is set on each connecting bolt 7, tightening nut, compression shock absorption spring to a certain extent,
Obtain suitable elastic force.
The utility model is a kind of buffer unit easy for installation, Simple And Practical, but can not accomplish very to protect,
