Description
Technical field
The utility model is related to the centre-driven device of a kind of lifting center drive mud-scraper, thickener or mixer, this practicality
It is new more particularly, to a kind of centre-driven device with overload protection function.
Background technology
Centre-driven device is applied in the complete set of equipments of lifting center drive mud-scraper, thickener or mixer, drive device
Moment of torsion is provided to be suspended on the mud-scraping apparatus, enrichment facility or agitating device of its underpart, overload protective device is used for apparatus overload
When, the workpiece of drive device lower suspension is shut down and send alarm signal.
The structure of traditional centre-driven device is as shown in figure 1, safety pin 1 runs through first shaft coupling 2 and second shaft coupling
3, first shaft coupling 2 is connected by flat key with providing the speed reducer output shaft 4 of active force, and second shaft coupling 3 is by flat key with passing
Moving axis 5 is connected.Power is transferred to the safety pin 1 sheared by first shaft coupling 2, and then is transferred to second shaft coupling 3, so that
Power transmission shaft 5 is driven to rotate.
When the actual resistance moment of torsion of power transmission shaft 5 reaches design load, safety pin 1 reaches its material because of suffered shear stress
Shear defect and be broken, power transmission shaft 5 will stop operating.
Although the centre-driven device of this Purely mechanical can be without damage with protection equipment, after safety pin 1 is broken, subtract
Fast machine is still being rotated further, and the operating personnel of Central Control Room are not aware that equipment shuts down because of overload, i.e. traditional structure
Overload protective device do not possess knowability.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art not only can be with protection equipment not there is provided one kind
The centre-driven device with overload protection function for the operating personnel that is damaged and can remind Central Control Room.
The technical scheme provided according to the utility model, the centre-driven device with overload protection function, including
Safety pin, first shaft coupling, second shaft coupling, speed reducer output shaft, power transmission shaft, support and fulcrum bearing；It is fixed with support
Fulcrum bearing, is provided with reductor in fulcrum bearing, and first shaft coupling is provided with by key on speed reducer output shaft, in reductor
The lower section of output shaft is provided with power transmission shaft, and second shaft coupling, second shaft coupling and first shaft coupling are provided with by key in power transmission shaft
Mutually fixed by safety pin；Switch installation board is further fixed in fulcrum bearing, proximity switch is fixed with switch installation board；
Triggering breach is offered in the second shaft coupling, triggering breach coordinates with proximity switch.
It is uniform in second shaft coupling to offer described triggering breach.
The utility model is simple in construction, easy to use, and the utility model not only can be without damage with protection equipment, Er Qieke
To remind the operating personnel of Central Control Room, possesses knowability.
Brief description of the drawings

Fig. 2 is structural representation of the present utility model.
Fig. 3 is the front view of second shaft coupling in the utility model.
Fig. 4 is the top view of second shaft coupling in the utility model.
Embodiment
With reference to specific embodiment, the utility model is described in further detail.
This has a centre-driven device of overload protection function, including safety pin 1, first shaft coupling 2, second shaft coupling 3,
Speed reducer output shaft 4, power transmission shaft 5, support 6 and fulcrum bearing 7；Fulcrum bearing 7 is fixed with support 6, is provided with fulcrum bearing 7
Reductor, first shaft coupling 2 is provided with speed reducer output shaft 4 by key, in the lower section of speed reducer output shaft 4 provided with transmission
Axle 5, is provided with second shaft coupling 3, second shaft coupling 3 is mutually solid by safety pin 1 with first shaft coupling 2 in power transmission shaft 5 by key
It is fixed；Switch installation board 8 is further fixed in fulcrum bearing 7, proximity switch 9 is fixed with switch installation board 8；Described second
Triggering breach 3.1 is offered on axle device 3, triggering breach 3.1 coordinates with proximity switch 9.
It is uniform in second shaft coupling 3 to offer described triggering breach 3.1.
The utility model fixes switch installation board 8 on the inwall of fulcrum bearing 7 with fastener, pacifies on switch installation board 8
Proximity switch 9 is filled, and proximity switch 9 is aligned the side of second shaft coupling 3, triggering is offered in the second shaft coupling 3
Breach 3.1.
During normal operation, fixed proximity switch 9 will continuously sense second shaft coupling 3 every certain setting time
Side, when second shaft coupling 3 turns over certain angle, proximity switch 9 just no longer senses second in certain setting time
The side of axle device 3.So, the induced signal that Central Control Room is received is exactly periodic.As long as this cycle is in setting range, just
Illustrate that equipment operation is normal.After safety pin 1 is broken, second shaft coupling 3 will stop operating, the induced signal that Central Control Room is received
Cycle be changed, the overload protective device that will send alarm signal, i.e. improved structure possesses knowability.
