Abstract
The utility model discloses a reducer backstopping device special for inclined mine conveyor. The reducer backstopping device comprises a fixed round plate, a backstop gear plate, a limiting backstop claw, a base, a fixed frame, a limit spring, bolts and the like. The reducer backstopping device is characterized in that a reducer rolling cylinder is fixedly connected with the fixed round plate; the fixed round plate is fixedly connected with the backstop gear plate through the bolts, the limiting backstop claw matches with the backstop gear plate and is connected with the fixed frame through the limit spring, and the base is fixedly connected with the fixed frame. According to an embodiment with a figure, the reducer backstopping device is detailedly characterized in that a reducer rolling cylinder is fixedly connected with the fixed round plate1; the fixed round plate1 is fixedly connected with the backstop gear plate 2 through the bolts 7, the limiting backstop claw 3 matches with the backstop gear plate 2 and is connected with the fixed frame 5 through the limit spring 6, and the base 4 is fixedly connected with the fixed frame 5.
Description
Technical field
The utility model relates to non-return device under the coal mine, especially relates to a kind of coal mine sloping lane and carries the special reduction gear non-return device, belongs to colliery lifting means technical field.
Background technology
" safety regulations in coal mine " the 373 regulation: the belt conveyer that uses in the gradient tunnel, on when transporting, must install anti-kickback device and brake equipment simultaneously; Under when transporting, must the installing brake equipment.
At present, in the Coal Production, because the conditions down-hole complexity usually the down-hole serious accident can take place.When the conveyor load material moves because factor such as power interruption, can under machinery situation local or all delivered length loaded material, stop transport, if being loaded with material, to have the downward gravity effect of the conveyer at the angle of inclination friction drag more all than transportation device all big, will be in a non-equilibrium state so, unless controlled by other equipment otherwise belt will move backward and causes belt feeder to reverse, in this case, feed end can not be taken the material of transporting back away, will cause the accumulation of band conveyor afterbody material to leak or suitable sliding phenomenon, this will cause damage to rubber tape or afterbody equipment, is a serious potential safety hazard.
In order to prevent at inclined conveyer, when load is shut down reversing or suitable sliding phenomenon taking place, need set up non-return device.Non-return device generally is installed in reductor low speed end, and exist not enough in the process of using: during shutdown, non-return effect is not strong; Service life is short, installation and maintenance is inconvenient; Replacing is frequent, recondition expense is high.
Summary of the invention
The utility model is at the deficiencies in the prior art, provide a kind of check effective, rational in infrastructure, operate and overhaul easily coal mine sloping lane and carry the special reduction gear non-return device.
For realizing this purpose, the technical scheme that the utility model is taked is: a kind of coal mine sloping lane carries the special reduction gear non-return device to be made up of fixed disc, check toothed disc, spacing anti-reverse claw stop, base, fixed mount, spacing extension spring, bolt etc., its technical characterictic is: the reductor cylinder is captiveed joint with fixed disc, fixed disc and check toothed disc are bolted to connection, spacing anti-reverse claw stop and check toothed disc are complementary, spacing anti-reverse claw stop joins by spacing extension spring and fixed mount, and base is captiveed joint with fixed mount.
The beneficial effects of the utility model are: have that installation and maintenance are easy, result of use is reliable, low cost of manufacture, long service life.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model, in the drawings: 1, fixed disc; 2, check toothed disc; 3, spacing anti-reverse claw stop; 4, base; 5, fixed mount; 6, spacing extension spring; 7, bolt.
The specific embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing: a kind of coal mine sloping lane carries the special reduction gear non-return device to be made up of fixed disc, check toothed disc, spacing anti-reverse claw stop, base, fixed mount, spacing extension spring, bolt etc., the reductor cylinder is captiveed joint with fixed disc 1, fixed disc 1 is captiveed joint by bolt 7 with check toothed disc 2, spacing anti-reverse claw stop 3 and check toothed disc 2 hurdles coupling, spacing anti-reverse claw stop 3 joins with fixed mount 5 by spacing extension spring 6, and base 4 is captiveed joint with fixed mount 5.
During use; fixed disc 1 is welded on the axle of reductor cylinder one side; again check toothed disc 2 is fastened on the fixed disc 1; at the spacing anti-reverse claw stop 3 of base 4 fixed installations, because spacing anti-reverse claw stop 3 is complementary with check toothed disc 2, spacing anti-reverse claw stop 3 joins with fixed mount 5 by spacing extension spring 6; when making belt carry running; the shutdown check can be reached, no potential safety hazard need be stopped to stop immediately.
Claims (1)
