Abstract
A downward transport belt conveyor energy-saving braking system which comprises a low-power electromotor, a worm and gear speed reducer, a belt driving roller and a braking device, wherein a motor shaft is connected with a worm of the worm and gear speed reducer, and a driving roll is connected with a worm wheel of the worm and gear speed reducer; a pulling stress sensor is arranged in the axial direction of the worm, the system further comprise a control module, and the control module is respectively connected with the pulling stress sensor and the braking device. According to the downward transport belt conveyor energy-saving braking system, combination of the low-power electromotor, the worm and gear speed reducer and the pulling stress sensor is adopted, low-speed starting and low-speed operating of a downward transport belt can be achieved, and galloping effects are avoided.
Description
Technical field
The present invention relates to the technical field of belt feeder, particularly relate to the energy-conservation brake system of a kind of lower fortune belt feeder.
Background technology
Lower fortune belt feeder of the prior art is all generally to adopt large electrical motor to use as resistance, prevent the driving that exceeds the speed limit, but the strength that lower fortune belt needs when starting is not very large, the startup strength of large electrical motor is too large, being used for starting lower fortune belt feeder relatively wastes energy, when lower fortune belt normal operation, large electrical motor is to absorb as resistance potential energy that belt material discharges when descending, this design form, cost is high on the one hand, the feature of the electrical motor also not making full use of on the other hand self, haves much room for improvement.
Summary of the invention
To the object of the invention is in order addressing the above problem, to provide a kind of lower fortune belt feeder energy-conservation brake system.
Technical scheme of the present invention is: the energy-conservation brake system of a kind of lower fortune belt feeder, comprise low power electrical motor, worm-gear speed reducer, belt drive cylinder, brake gear, described motor shaft connects the worm screw of worm-gear speed reducer, and driven roller connects the worm gear of worm-gear speed reducer; Worm screw be axially arranged with tensile stress sensor, this system also comprises control module, described control module connects respectively tensile stress sensor and brake gear.
Described control module at least comprises memory device, A and D converter, arithmetic and logic unit.
Beneficial effect of the present invention
The energy-conservation brake system of this lower fortune belt feeder, adopts the combination of small power motor, worm-gear speed reducer and pulling force sensor, can reach the low rate start of lower fortune belt, and low cruise prevents the effect of driving.
Accompanying drawing explanation
Fig. 1 is the energy-conservation brake system principle schematic of lower fortune belt feeder;
1. brake gears in figure, 2. control module, 3. tensile stress sensor, 4. worm screw, 5. turbine, the 6. driven roller of belt feeder.
The specific embodiment
Embodiment: referring to Fig. 1, the energy-conservation brake system of a kind of lower fortune belt feeder in figure, comprise low power electrical motor, worm-gear speed reducer, belt drive cylinder, brake gear, described motor shaft connects the worm screw of worm-gear speed reducer, and driven roller connects the worm gear of worm-gear speed reducer; Worm screw be axially arranged with tensile stress sensor, this system also comprises control module, described control module connects respectively tensile stress sensor and brake gear.Brake gear can be selected various brake of the prior art, satisfies the demands and can control by circuit.Described control module at least comprises memory device, A and D converter, arithmetic and logic unit.
The worm-gear speed reducer that first this brake system is utilized starts, the speed ratio of this retarder is large, can on turbine, produce larger moment of torsion, low power like this electrical motor just can meet startup requirement, worm-gear speed reducer also has non-return effect simultaneously, can stop to a certain extent belt feeder hypervelocity.
When lower fortune belt operation, if all rely on turbine worm reducer control rate, can on worm and gear, produce amount of heat, likely damage turbine worm reducer, just need a brake gear cooperating, on worm screw, load onto tensile stress sensor, can measure the stressing conditions of worm screw, thereby can calculate the stressing conditions on turbine, then the stressing conditions that the logical sensor of control module is measured is controlled the braking strength of brake gear, thereby realize, to worm and gear, subtract underloaded object, reach the effect of the two matching coordinative work.
Claims (2)
1. transport the energy-conservation brake system of belt feeder under one kind, comprise low power electrical motor, worm-gear speed reducer, belt drive cylinder, brake gear, it is characterized in that: described motor shaft connects the worm screw of worm-gear speed reducer, driven roller connects the worm gear of worm-gear speed reducer; Worm screw be axially arranged with tensile stress sensor, this system also comprises control module, described control module connects respectively tensile stress sensor and brake gear.
2. the energy-conservation brake system of lower fortune belt feeder according to claim 1, is characterized in that: described control module at least comprises memory device, A and D converter, arithmetic and logic unit.
