Abstract
The utility model particularly discloses a switch magnetic resistance control type speed regulation scraper conveyor. Driving systems which are arranged at a machine head and a machine tail of the conveyor respectively are switch magnetic resistance motor speed regulation systems. Each switch magnetic resistance motor speed regulation system comprises a switch magnetic resistance controller which is used for controlling a switch magnetic resistance motor, wherein an output shaft of the switch magnetic resistance motor is connected with an input end of a reducer through an elastic coupling and an output end of the reducer is connected with a machine head chain wheel shaft group. According to the switch magnetic resistance control type speed regulation scraper conveyor, the low speed starting of heavy loads can be achieved and the power grid and mechanical impact is avoided; the real-time rapid regulation on the running speed of a scraper can be performed to adapt to various complex conditions, the reactive abrasion is reduced, and the service life is extended; the speed regulation systems are stable and reliable and low in failure rate.
Description
Technical field
The utility model designs a kind of scraper conveyor for coal mines, relates in particular to a kind of switching magnetic-resistance control system and drives, the slat conveyer of adjustable scrapping plate chain running velocity.
Background technology
Slat conveyer, by direct motor drive, drives round-link chain, scraper plate to do circulating motion in conveyer intermediate channel by hydraulic coupler, retarder, sprocket wheel, thereby realizes transportation coal, supports the use with coalcutter, hydraulic support, elevating conveyor etc.Coal is transported to elevating conveyor by slat conveyer, is transported to immediately the equipment such as belt feeder, until be transported to ground.Slat conveyer performance directly affects the production efficiency in colliery thus.
At present slat conveyer generally adopts the type of drive of single speed or double-speed motor, often occurs following fault in use procedure: 1. occurring during conveyer heavy load starting cannot startup, chain rupture, beat tooth, roll the physical damage phenomenons such as key.2. starting current is large, to downhole area electrical network, impacts larger.3. instantaneous freight volume is excessive or when too small, causes the alluvial of elevating conveyor coal or transport plane Efficiency Decreasing to cause waste.4. frequent starting electrical motor, causes motor overheating and even burns.5. hydraulic coupler fault rate is high, incurs loss through delay and produces.The above slat conveyer fault that takes place frequently greatly affects coal work efficiency, restriction coal production.
Summary of the invention
The purpose of this utility model is exactly in order to solve the problem that slat conveyer heavy load starting is difficult, starting current is excessive, freight volume cannot regulate, motor temperature is too high, provide a kind of and realize that heavy-duty low-speed starts, transportation volume is adjustable, can adapt to the slat conveyer of various working.
For achieving the above object, the utility model has adopted following technical scheme:
Switching magnetic-resistance is controlled a speed governing slat conveyer, at the head of described conveyer and the drive system of tail, is SRD.
Described SRD, comprise switch magnetic resistance controller, described switch magnetic resistance controller master cock magnetic group motor, the output shaft of described switch magnetic group motor connects the input end of reductor by an elastic coupling, the mouth of described reductor connects head sprocket shaft group or tail sprocket shaft group.
The controller of described conveyer head and the SRD of tail is connected with same control box.
Between described head and the switch magnetic resistance controller of tail, pass through CAN bus communication.
The utility model changes the drive system of slat conveyer into SRD.Motor is connected employing elastic coupling with reductor, save hydraulic coupler.Between control box and speed regulation device, be connected control line, realize the controls such as start and stop, speed governing; Between head, two speed regulation devices of tail, adopt CAN communication, realize two-shipper torque, synchronization operation; Two speed regulation devices now interlock by I/O cause for gossip, automatic shutdown protection when head or tail speed regulation device fault, and closing fault device can be realized monomotor operation.
Switched reluctance machines detent torque is large, can reach 150% of torque rating; Starting current is little, is only 30% of rated current; Electrical motor can be realized 200r/min to rated speed of rotation stepless time adjustment; Electrical motor self structure is double-salient-pole structure, and without cage-shaped structure, mechanical strength is high, reliability and durability.
The beneficial effects of the utility model are: slat conveyer can be realized heavy-duty low-speed and start, without electrical network and mechanical impact; Can regulate real-time scraper plate running velocity, tackle various complex working conditions, reduce idle wearing and tearing, increase the service life; Speed governing system is steadily reliable, failure rate is low.
