Abstract
A drive mechanism protection device comprises a drive shaft connected with a motor, a driven shaft connected with the drive shaft, a detection sheet is provided on the driven shaft, a bearing base fixing bracket is arranged outside the driven shaft, a stall detection device is arranged on the bearing base fixing bracket and is connected with the motor by a control unit, when the rotating of the detection sheet is abnormal, the stall detection device can provide a signal to the control unit for in time cutting off the power supply of the motor. The utility model can protect the system, monitor the operating condition of the device, and protect the safe operation of the device, and has advantages of simple structure, low cost, convenient operation, and strong adaptability, and the utility model is applicable to operation under various operating conditions.
Description
Technical field
The utility model relates to a kind of transmission device fender guard.
Background technology
On the load transfer devices such as present bucket elevator, embedded scraper transporter, conveyor screw, band conveyor and firm revolving plow reclaimer, all be provided with transmission device, during the conveyer normal operation, its driven shaft together rotates with imput shaft, driven shaft keeps a certain rotating speed, when motor and mechanical drive during because of fault generations such as stall, card commentaries on classics, overload, slow-speed, slipping of the belt, messenger chain (band) come off, drive shafts fractures, its output speed descends significantly, cause stall, but its imput shaft is still rotated, be prone to accidents, cause device damage.
The utility model content
The utility model technical issues that need to address provide a kind of transmission device fender guard to reach when the mechanical drive et out of order, stop imput shaft and rotate the purpose of preventive device.
In order to solve the problems of the technologies described above; the technical solution of the utility model is; a kind of transmission device fender guard; comprise a kind of transmission device fender guard, comprise and motor bonded assembly imput shaft, with imput shaft bonded assembly driven shaft; described driven shaft is provided with detection lug; described driven shaft is provided with the bearing seat fixed mount outward, and described bearing seat fixed mount is provided with the stall detecting device, and described stall detecting device is connected with motor by control unit.
Described driven shaft passes detection lug, and detection lug is fixed on the driven shaft by thru-bolt.
Described detection lug is vertical with driven shaft to be provided with.
Described stall detecting device is fixed on the bearing seat fixed mount by the fixed support of " L " shape.
The probe of described detection lug and stall detecting device be arranged in parallel.
Described detection lug is " word " shape or " cross " shape etc.
The utility model compared with prior art, driven shaft is provided with detection lug, detection lug rotates unusual thing, the stall detecting device can provide signal in time to cut off motor power to control unit, protection system, the operational situation of monitoring equipment, preventive device safe operation.And simple in structure, with low cost, easy to operate, adaptive capacity is strong, is fit to move under the various operating modes.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further details;
Fig. 1 is the utility model structural representation;
In Fig. 1,1, driven shaft, 2, detection lug, 3, thru-bolt, 4, the stall detecting device, 5, fixed support, 6, the bearing seat fixed mount.
The specific embodiment
As shown in Figure 1; a kind of transmission device fender guard; comprise a kind of transmission device fender guard; comprise and motor bonded assembly imput shaft; with imput shaft bonded assembly driven shaft 1, described driven shaft 1 is provided with detection lug 2, the described driven shaft 1 outer bearing seat fixed mount 6 that is provided with; described bearing seat fixed mount 6 is provided with stall detecting device 4, and described stall detecting device 4 is connected with motor by control unit.
Described driven shaft 1 passes detection lug 2, and detection lug 2 is fixed on the driven shaft 1 by thru-bolt 3.
Described detection lug 2 and driven shaft 1 vertical setting.
Described stall detecting device 4 is fixed on the bearing seat fixed mount 6 by the fixed support 5 of " L " shape.
Described detection lug 2 be arranged in parallel with the probe of stall detecting device 4.Prevent interference.
Described detection lug 2 sizes 100 * 10 * 1.5mm, material is A
3Stalloy can be formed various ways such as " word " shape or " cross " shape.
When the electrical motor normal operation, rotate by initiatively ordering about driven shaft 1, detection lug 2 on the driven shaft 1 also rotates thereupon, stall monitoring device 4 receives the even spacing pulse signal of detection lug 2, stall this moment monitoring device 4 is a closure state, control unit receives the closure signal of stall detecting device, the control motor is rotated further, when motor and mechanical drive because of stall, card changes, overload, slow-speed, slipping of the belt, messenger chain (band) comes off, when faults such as drive shafts fracture take place, its driven shaft 1 rotating speed descends significantly, also slow-speed or the stall thereupon of detection lug 2 this moment.Fixed time interior (3-5 second) does not also have the rotational pulse signal to send, and stall monitoring switch will transfer disconnection to by closure state, and control unit control motor stops operating in second at 3-5, in time shuts down reliable protection equipment.
