Abstract
The utility model provides an anti-plugging automatic control switch. The utility model comprises a bottom plate, wherein, the bottom plate is provided with a micro switch. The utility model is characterized in that the bottom plate is hinged with a valve plate which can move up and down and oppress or disengage from the micro switch. The utility model is arranged on conveying pipeline walls of belts or belt like transport systems. When the plugging phenomenon is generated, the stemming downwards presses the valve plate, the valve plate downwards moves and oppresses the micro switch, the micro switch is broken, power supplies of electric motors of the belts or the belt like rotation systems are cut off, and thus the utility model prevents the conveying pipelines from being continuously blocked.
Description
The utility model provides a kind of anti-clogging automatic control switch, be applicable to that the fire coal transportation of metallurgy, smelting, mining, thermoelectric power station and Chemical Manufacture etc. are a series of need system with belt and belt-like transhipment in.
In a series of systems that need transport with belt and belt-like such as the fire coal transportation of existing metallurgy, smelting, mining, thermoelectric power station and Chemical Manufacture, because detecting device is not set in movement system, when stopping up appears in the somewhere in the transhipment, will cause the movement system of latter part to stop up, make movement system under the transported material impassabitity, thereby influenced the service life of movement system, and the service efficiency of equipment.
The purpose of this utility model is to provide a kind of anti-clogging automatic control switch, is adapted to be mounted within on the delivery duct of movement system, when latch up phenomenon occurring, can prevent the generation and the recovery of latch up phenomenon by cutting off the power supply of electrical motor.
The purpose of this utility model is achieved in that it comprises base plate, and base plate is provided with micro-switch, and it is characterized in that being hinged with on the described base plate can the upper and lower valve plate that moves and then oppress or break away from micro-switch.The utility model is installed on the delivery duct wall in the system of belt or belt-like transhipment, when latch up phenomenon occurring, tamper is to pressing down valve plate, valve plate moves down depresses micro-switch, micro-switch disconnects, the power supply of the electrical motor in the system of cut-out belt or belt-like transhipment, it is blocked to stop delivery duct to continue.
One end of above-mentioned valve plate has been welded to connect hinge sleeve, is set with hinge axis in the hinge sleeve, and articulated axle places on the base plate, and its both ends are contained in the fixed card that is connected with base plate.Thereby valve plate is hinged on the base plate, valve plate can be rotated with respect to base plate.
Have corresponding hole on the appropriate location of above-mentioned valve plate and base plate, axle is housed in the hole, be set with pull back spring on the axle, pull back spring is spacing by valve plate and base plate.After tamper was eliminated, valve plate can self-return under the effect of pull back spring.
Be fixedly connected with the switch protection cover on the above-mentioned base plate, micro-switch is fixedly connected in the switch protection cover.Micro-switch is connected in the control circuit of electrical motor for contact or contact pointless normally closed switch or travel switch are arranged, after valve plate moves self-return under the effect of pull back spring, and the micro-switch closure, electrical motor resumes operation.
The utlity model has following characteristics:
Reasonable in design, the degree of automation height, circuit arrangement safety, characteristics such as barrier propterty is good, checks easy to maintenancely, and has the breaking capacity height, and the dynamic and thermal stability performance is good, and is safe and reliable to operation are installed the influence that is not subjected to surrounding environment, antidetonation, diamagnetic, mechanical wear is little.
Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 mounting structure scheme drawing of the present utility model.
Fig. 2 schematic circuit diagram of the present utility model.
With reference to figure 1; The utility model comprises base plate 1; have hole 2 on four angles of base plate 1; be connected with the delivery duct wall of movement system by threaded connector with convenient; on the appropriate location of base plate 1, be welded to connect switch protection cover 3; switch protection cover 3 internal fixation are connected with micro-switch 4; switch protection cover 3 tops have the hole, and the top of micro-switch 4 is passed institute's perforate on the switch protection cover 3 and placed outside the hole.One end of base plate 1 has groove, and being hinged with on the groove can the upper and lower valve plate 5 that moves and then break away from or oppress micro-switch.One end of valve plate 5 has been welded to connect hinge sleeve 6, be set with hinge axis 7 in the hinge sleeve 6, hinge axis 7 places on the base plate 1, its two ends are contained in the fixed card 8 that is connected with base plate 1, fixed card 8 is connected on two edges of base plate 1 end institute recessing by threaded connector, on the appropriate location of valve plate and base plate, have corresponding hole, axle 9 is housed in the hole, institute's perforate is connected on the lower end of axle 9 and the base plate 1, the upper end of axle 9 is passed institute's perforate on the valve plate 5 and is placed on the valve plate 5, is set with pull back spring 10 on the axle 9, and pull back spring 10 is spacing by valve plate 5 and base plate 1.
With reference to figure 2: Fig. 2 is schematic circuit diagram of the present utility model, and LXW is a micro-switch 4 among the figure, and micro-switch is for there being the contact normally closed switch, one relay termination K, the contact of another termination starter button QA and relay K, TA is a halt switch, RD is insurance, and QS is a source switch, and D is an electrical motor.
