The device comprises a shell (4), wherein a spiral body (2) is arranged in the shell (4); and the device is characterized by also comprising a rotating speed detector (3) and a driving reducer (1), wherein the rotating speed detector (3) is arranged on the shell (4) close to one end of the spiral body (2) and used for detecting rotation of the spiral body (2); the driving reducer (1) is connected with the rotating speed detector (3); and a feeding hole (5) and a discharging hole (6) are formed in the shell (4); and the driving reducer (1) is arranged on the outer side of the shell (4) and at the other end of the spiral body (2).
Description
Technical field
The utility model belongs to the monitoring and protecting device, particularly conveyor screw operational monitoring fender guard.
Background technology
Conveyor screw is widely used in the solid of industries such as mine, agricultural, environmental protection, building or the conveying of semifluid material.This equipment is because what carry is solid or semifluid material, occurs through regular meeting that conveyor screw is twined, stuck and situation that equipment is overloaded.If there is not the proper protection measure, equipment is easy to be damaged.In case the equipment overload just possibly make the major part-conveyor screw of equipment or drive speed reducer damage, and causes heavy losses.Traditional method is to rely on the overload protection of motor itself or detection motor output torque to protect.But this key protection point is the protection drive part, is difficult to conveyor screw is protected.
Summary of the invention
In order to overcome above-mentioned defective; For overcoming the problem that exists in the existing installation use; The utility model proposes a kind of device that actuating device and conveyor screw are effectively protected simultaneously of being used for, and with drive motor fender guard formation double insurance, equipment can more safely be moved.
For realizing above-mentioned utility model purpose, conveyor screw operational monitoring fender guard is proposed, this device comprises housing, is provided with conveyor screw in the said housing; It is characterized in that, also comprise the rotating speed detector and the drive speed reducer that are used to survey said conveyor screw rotation; Said rotating speed detector places on the said housing near conveyor screw one end, and said drive speed reducer links to each other with said rotating speed detector.
More preferably, said housing is provided with inlet point and discharging opening.
More preferably, said drive speed reducer places hull outside and is positioned at the said conveyor screw other end.
The advantage of the utility model is that this device acquisition cost is low, simple installation, and result of use is good.This device passes through monitoring conveyor screw rotation speed monitoring conveyor screw operation conditions, and determines whether to carry out parking procedure to equipment important spare part enforcement protection according to operation conditions.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, the technical scheme of the utility model is carried out further detailed explanation.
As shown in Figure 1, Fig. 1 is the structural representation of the conveyor screw operational monitoring fender guard of the utility model proposition.This device comprises housing 4, is used to survey the rotating speed detector 3 and the drive speed reducer 1 of conveyor screw 2 rotations; Be provided with conveyor screw 2 in the housing 4; Rotating speed detector 3 places on the housing 4 near conveyor screw 2 one ends, and drive speed reducer 1 places conveyor screw, and links to each other with said rotating speed detector, and housing 4 is provided with inlet point 5 and discharging opening 6.
Can know from Fig. 1; Rotating speed detector 3 is installed on the screw conveyor housing 4 near the terminal position of conveyor screw 2; Make rotating speed detector 3 can detect conveyor screw 2 easily through out-of-date in conveyor screw 2 rotations; Be unlikely to damage probe again but be transferred material, through the detectable signal line rotating speed detector 3 and drive speed reducer 1 coupled together then, corresponding overload protection program is set.
The principle of work that the utility model relates to conveyor screw conveyor screw fender guard is: on apparatus casing 4, near conveyor screw 2 tail ends a rotating speed detector 3 is installed; Conveyor screw 2 whenever revolves and turns around; Rotating speed detector 3 just can detect a signal; During normal operation, rotating speed detector 3 detected s-fs should be consistent with drive speed reducer 1 speed-frequency.In case conveyor screw 2 any positions are twined or blocked, the s-f that tail end monitors is with slack-off or stop, if in setting-up time, do not detect signal, electric machine control system will stop its operation with device powers down, realizes the protection to equipment.
When conveyor screw moves,, be that the helical feed load becomes big in case stuck spiral of material or winding screw are arranged; Conveyor screw 2 rotating speeds will be at first slack-off; Make conveyor screw 2 rotating speeds and drive speed reducer 1 output shaft rotating speed form speed discrepancy, increasing when load, conveyor screw 2 speed are slack-off gradually when reaching setting value; Tachogen 3 will send stop signal to electric machine control system rapidly, system is in time stopped the equipment vitals is protected to greatest extent.
It should be noted last that above embodiment is only unrestricted in order to technical scheme of the present invention to be described.Although the present invention is specified with reference to embodiment; Those of ordinary skill in the art is to be understood that; Technical scheme of the present invention is made amendment or is equal to replacement, do not break away from the spirit and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
