Description
Technical field
The present invention relates to the centre-driven device of a kind of lifting center drive mud-scraper, thickener or mixer, the present invention is especially
It is to be related 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, driving means
Mud-scraping apparatus, enrichment facility or agitating device for being suspended on its underpart provide moment of torsion, and overload protective device is used for apparatus overload
When, so that the workpiece of driving means 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 passed through flat key and is connected with the speed reducer output shaft 4 providing active force, and second shaft coupling 3 passes through flat key and biography
Moving axis 5 connects.Power is transferred to the safety pin 1 sheared by first shaft coupling 2, and then is transferred to second shaft coupling 3, thus
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 rupture, 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 fracture, 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.
Content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, provide one kind not only can protection equipment not impaired
Go bad and the centre-driven device with overload protection function of the operating personnel of Central Control Room can be reminded.
The technical scheme providing according to the present invention, the described 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；Supporting is fixed with support
Seat, is provided with reductor in fulcrum bearing, is provided with first shaft coupling by key on speed reducer output shaft, in reductor output
The lower section of axle is provided with power transmission shaft, is provided with second shaft coupling in power transmission shaft by key, and second shaft coupling is passed through with first shaft coupling
Safety pin phase is fixed；Switch installation board is further fixed on fulcrum bearing, proximity switch is fixed with switch installation board；Described
Triggering breach is offered on second shaft coupling, triggering breach and proximity switch coordinate.
Described triggering breach is uniformly offered on second shaft coupling.
Present configuration is simple, easy to use, the present invention not only can protection equipment without damage, and in can reminding
The operating personnel of control room, possess knowability.
Brief description
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation of the present invention.
Fig. 3 is the front view of second shaft coupling in the present invention.
Fig. 4 is the top view of second shaft coupling in the present invention.
Specific embodiment
With reference to specific embodiment, the invention will be further described.
This has the 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, fulcrum bearing 7 is provided with
Reductor, is provided with first shaft coupling 2 by key on speed reducer output shaft 4, is provided with transmission in the lower section of speed reducer output shaft 4
Axle 5, is provided with second shaft coupling 3 in power transmission shaft 5 by key, it is mutually solid that second shaft coupling 3 and first shaft coupling 2 pass through safety pin 1
Fixed；Switch installation board 8 is further fixed on fulcrum bearing 7, proximity switch 9 is fixed with switch installation board 8；Described second
Triggering breach 3.1 is offered on axial organ 3, triggering breach 3.1 is coordinated with proximity switch 9.
Described triggering breach 3.1 is uniformly offered on second shaft coupling 3.
The present invention fixes switch installation board 8 with securing member on the inwall of fulcrum bearing 7, installs and connect on switch installation board 8
Nearly switch 9, and make proximity switch 9 align the side of second shaft coupling 3, described second shaft coupling 3 offers triggering breach
3.1.
During normal operation, fixing 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 axial organ 3.So, the induced signal that Central Control Room receives is exactly periodic.As long as this cycle is in setting range, just
Illustrate that equipment operation is normal.After safety pin 1 ruptures, second shaft coupling 3 will stop operating, the induced signal that Central Control Room receives
Cycle be changed, alarm signal will be sent, that is, the overload protective device of improved structure possesses knowability.
