Abstract
The utility model discloses a decelerator with an inverted device, which comprises a decelerator cabinet (1), a second decelerator shaft (2), a primary decelerator shaft (3) and a shaft coupling (4); wherein the second decelerator shaft (2) is provided with a holdback (5); the holdback (5) and the second decelerator (2) are connected with parallel keys; the holdback (5) is fixed on the base of the reduction gearbox (1). The utility model changes the original second decelerator shaft into an extended shaft and is provided with a holdback thereon. Compared with the original decelerator that uses the braking shaft and the long-shat head at the same time, the utility model has saved the braking sluice of the belt conveyor, thereby greatly reducing the frequency of the equipment accidence and maintenance of the belt conveyor. Therefore, the utility model is a decelerator with an inverted device. The model has the advantage of a simple structure and safety and is used in the STJ1000/125S belt conveyor.
Description
Technical field
The utility model relates to exploiting field, a kind of colliery centralized transportation system, specifically a kind of speed reducer that prevents the band non-return device that belt conveyer reversing accident takes place.
Background technique
The STJ1000/125S belt conveyer is widely used in exploiting field, colliery centralized transportation system, and when belt conveyer was tilted to transportation, the braking device of belt conveyer adopted the power hydraulic pressure pusher brake, and non-return device adopts the check band.Behind this belt conveyer electrification hydraulic push-rod brake, its speed reducer input shaft must use band brake brake wheel major axis head, causes the dynamic unbalance of speed reducer input shaft, and the speed reducer input shaft is damaged easily, and the generator electrification influences the raw coal transportation.The check band is limited by intensity in addition, when the fully loaded shutdown of belt conveyer, belt conveyer reversing accident takes place easily.
Summary of the invention
The purpose of this utility model is exactly for solving the speed reducer input shaft rapid wear phenomenon that STJ1000/125S belt conveyer electrification hydraulic push-rod brake brings, prevent the generation of belt conveyer reversing accident, and provide a kind of simple in structure, the speed reducer of band non-return device safe in utilization.
The utility model is to realize like this, the speed reducer of band non-return device, comprise deceleration cabinet, two of speed reducers, one of speed reducer, coupling, its main points are: install non-return device additional on two of speed reducers, two flat keys of non-return device and speed reducer are connected, and non-return device is fixed on the base of deceleration cabinet.To prevent that speed reducer from reversing, and guarantees the normal operation of belt conveyer.
Two of described belt conveyer speed reducers are extension shaft.
Adopt the utility model, two with former speed reducer change extension shaft into, and non-return device is installed thereon, and the utility model is compared with the former speed reducer that uses stopping brake and major axis head, owing to removed belt conveyer stopping brake and check band, greatly reduced the equipment accident and the amount of maintenance of belt conveyer.Therefore, the utility model is a kind of speed reducer of the band non-return device that is used for the STJ1000/125S belt conveyer simple in structure, safe in utilization.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
As shown in drawings, belt conveyer non-contact non-return device includes and comprises deceleration cabinet 1, two 2 of speed reducers, one 3 of speed reducer, coupling 4, its main points are: install non-return device 5 additional on two 2 of speed reducers, two 2 flat keys of non-return device 5 and speed reducer are connected, and non-return device 5 is fixed on the base of deceleration cabinet 1.Two 2 of speed reducers are extension shaft.The working principle of non-return device 5:
In non-return device 5 inside, there are a plurality of voussoirs to be distributed in the raceway of inside and outside circle formation, when the inner ring forward turns round, drive voussoir and turn round together, voussoir deflects under action of centrifugal force when rotating speed surpasses the non-contact rotating speed, disengage with Internal and external cycle, thereby realize not having the wearing and tearing running, when the inner ring antiport, under the effect of spring force, voussoir contacts with Internal and external cycle and wedge is integral, and bears the opposing torque that is come by the inner ring transmission.
The utility model installs non-return device 5 additional on two 2 of speed reducers; it is 400～1500rpm that this non-return device 5 requires rotating speed; check moment 6300Nm; converse stopping mechanism is a voussoir, and after rotating speed reached 400rpm, voussoir broke away from cover in the non-return device by centrifugal force; non-contact is rotated; after belt conveyer is shut down, be adjacent in the non-return device cover and with the transmission shaft wedging at the effect lower wedge block of spring force, thereby realize preventing the purpose of its reversing.
Claims (2)
1, a kind of speed reducer with non-return device, comprise deceleration cabinet (1), speed reducer two (2), speed reducer (3), coupling (4), its main points are: install non-return device (5) additional on speed reducer two (2), two (2) flat keys of non-return device (5) and speed reducer are connected, and non-return device (5) is fixed on the base of deceleration cabinet (1).
2, the speed reducer of band non-return device according to claim 1 is characterized in that: described speed reducer two (2) is an extension shaft.
