A current known semi-steel radial tire forming machine carcass drum deciliter process drives ball-screw by motor reducer, and because ball-screw is arranged in carcass drum within axle, its duty cannot Real-Time Monitoring.And in actual process, be the overload fault such as the easy rotational resistance occurring that the gouging abrasion as excessively closely caused when carcass drum is fitted and leading screw excessive wear cause is large, if there is this type of fault, and fail Timeliness coverage, power source can not be cut off in time, great impact will be caused on device security and Forming Quality.
Summary of the invention
For the problems referred to above, the utility model provides a kind of semi-steel radial tire once-through method forming machine carcass drum deciliter overload protection arrangement, the fault of energy Real-Time Monitoring carcass drum separating/closing mechanism, and cuts off power source in time when breaking down.
For achieving the above object, the technical solution adopted in the utility model is: a kind of semi-steel radial tire once-through method forming machine carcass drum deciliter overload protection arrangement, comprise motor, motor driven belts wheel and interior driving shaft, interior driving shaft front end is connected with leading screw, also comprise mechanical overload protector and displacement detecting mechanism, mechanical overload protector comprises adpting flange, displacement flange and connecting bushing, connecting bushing is connected with interior driving shaft tail end, adpting flange is taken turns with motor driven belts and is connected, displacement detecting mechanism is located at by displacement flange, for detecting the lateral displacement of displacement flange, displacement detecting mechanism output and motor are electrically connected.When causing motor overload when breaking down; ball in overload protective device or steel ball depart from groove, and drive end parts and driven end parts produce and skid, and namely between adpting flange and connecting bushing, slipping occur; thus cause motor driven belts wheel to dally with interior driving shaft; displacement flange does moving axially of S shape, outwards throws off, and displacement detecting mechanism detects the displacement of its outside movement; when it exceedes setting value; export the signal turned off to motor, make motor stalling, stop carcass drum and divide closing operation.Cut off power source in time when ensure that overload, prevent from causing damage.
Further, for accurately measuring the displacement of displacement flange, preferably its displacement is delivered to far-end to measure, both the accuracy that position is detected can have been ensured, in turn ensure that safety problem during electric elements Installation and adjustment, the concrete structure adopted is: described displacement detecting mechanism comprise the synchronizing moving parts be located on displacement flange, with synchronizing moving component contact transmit the displacement transmission mechanism of its displacement and detect the sensing element of displacement transmission mechanism displacement.
Preferably, described synchronizing moving parts are around the fixing detection dish in displacement flange periphery.Select larger-diameter dish to act on displacement transmission mechanism, promote scope large, more accurate than promoting transmission in single point set.
Preferably, described displacement transmission mechanism comprises circular support plate, and circular support plate is provided with at least two scattering devices and the push rod passed vertically, push rod is connected by spring and spring spool with circular support plate, push rod one end contacts with detection dish, and the other end is fixedly connected with a displacement disc.During normal work; push rod is pressed on detection dish under the action of the spring; when overload protective device throws off skidding; detection dish is laterally thrown off with it and moves; move with the push rod of its close contact displacement disc that shipper pole moves its rear end backward; receive this signal by sensing element from carcass drum rear-end of spindle, thus control power source.For ensureing to promote effect, push rod has two at least, and the setting that keeps at a certain distance away, be preferably located at a circular board diameter two ends.
Preferably, described sensing element is proximity switch.Proximity switch is arranged on switch base, and output is connected with motor, when receiving disengagement actuating signal, cuts off motor.
Preferably, described mechanical overload protector is ball-type torque limiter or steel-ball type torque limiter.Generally comprise ball bearing, adpting flange, steel ball, groove, displacement flange, connecting bushing, butterfly spring, a few part of moment of torsion adjustment locking nut, its annexation is known, does not repeat them here.
The beneficial effects of the utility model are: when carcass drum deciliter breaks down, and overload protective device throws off skidding, thus avoids the damage caused because of overload.Change in location when simultaneously being thrown off by displacement detecting mechanism perception overload protective device, and send control signal, cutting off motor when transshipping, impelling a carcass drum deciliter motor to stop the rotation.This structure can detect the state of interior driving shaft in real time, can the safety of available protecting equipment, prevents device damage.

Detailed description of the invention
A kind of semi-steel radial tire once-through method forming machine carcass drum deciliter overload protection arrangement; as shown in the figure; comprise motor (not shown), motor driven belts wheel 2, interior driving shaft 1 and mechanical overload protector 3; described mechanical overload protector 3 adopts steel-ball type torque limiter; comprise ball bearing 12, adpting flange 13, steel ball 14, groove 15, displacement flange 16, connecting bushing 19, butterfly spring 17, moment of torsion adjustment locking nut 18; the internal structure of mechanical overload protector has been known, repeats no more.Adpting flange 13 and motor driven belts are taken turns 2 and are bolted, and connecting bushing 19 adopts axle-axle sleeve to be connected without backlash with interior driving shaft 1 tail end, and interior driving shaft front end connects ball-screw.This protection mechanism also comprises the detection dish 4 around being fixed on displacement flange 16 periphery; detection is coiled 4 offsides and is provided with a circular support plate 8; circular support plate 8 is provided with two push rods 5 axially passed; push rod 5 is connected by spring 7 and spring spool 6 with circular support plate 8; two push rod 5 one end contact with detection dish 4, and the other end is fixedly connected with a displacement disc 9.Displacement disc 9 offside is provided with a proximity switch 11, and proximity switch 11 is arranged on proximity switch seat 10, and is electrically connected with motor.
When motor works under rated load, torque limiter normally works, and the motor driven belts wheel belt action as drive end is drive shaft turns in driven end.When equipment breaks down generation overload, the rotation that interior driving shaft and motor driven belts are taken turns is asynchronous, cause the setting moment of torsion exceeding torque limiter, steel ball leaves groove, adpting flange and connecting bushing are thrown off, displacement flange generation axial displacement, thus drive the outwards movement of detection dish, promote push rod outwards movement, push rod drives displacement disc outwards movement, time within the detecting distance that displacement disc moves to proximity switch, proximity switch sends signal to motor, cutting off carcass drum deciliter motor, stop carcass drum and divide closing operation, avoiding because transshipping the damage caused motor.After overload fault is eliminated, steel ball automatically resets rotate an angle in retainer rotary course after in next groove, and adpting flange and connecting bushing reset, and interior driving shaft and motor driven belts wheel recover synchronous axial system.
