Background technique
Dry Quenching Technology is an energy-conserving and environment-protective technology of coal chemical technology, and is significant to the protection of the utilization of the energy and environment.Owing to the professional and particularity of dry quenching project technology, cause the construction cost height of dry coke quenching auxiliary, the equipment and supplies supply of material has become the bottleneck of dry quenching engineering development, is unfavorable for technical development and progress.
Coke dry-quenching loading device is located at the dried furnace roof portion of putting out, and the major function of charging apparatus is the dried bells etc. that put out of opening and closing, and when lift arrives the red burnt contraposition of canful dried when putting out the stove top, the opened dried bell that puts out of charging apparatus puts in place, and lift promptly begins volume down.Behind the burnt fallers seat, lift continues volume down, and burnt jar of end gate continues to descend with suspension rod under action of gravity, finishes the put-focus action of opening the door automatically.After red Jiao falls into hopper, through the cutting plate dried stove that puts out of packing into equably.After lift was sling slack tank, charging apparatus moved the dried bell that puts out steadily is put in the dried seal tank that puts out furnace roof portion, put out the stove sealing with dried.Moving back and forth of coke dry-quenching loading device is to be driven by an electronic cylinder at present, and electronic cylinder drives the subject matter that exists and is: 1, electronic cylinder screw mandrel head shaft causes stress to concentrate because vary in diameter is bigger, produces off-axis, the difficult reparation; 2, the electronic cylinder of the position signal of charging apparatus uses built-in encoder output, because the axial displacement of driving gear causes the inefficacy of Transmitted chains, makes built-in encoder output error signal, easily causes the serious accident of red bad equipment of incipient scorch; 3, the equipment purchase cycle is long and price is high.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of work operates steadily, not fragile, long service life, safe and reliable, equipment and maintenance cost is low, can satisfy and optimize the Electrohydraulic push rod of the coke dry-quenching loading device of dry quenching manufacturing technique requirent.
The technological scheme that solves the problems of the technologies described above is:
A kind of Electrohydraulic push rod of coke dry-quenching loading device, it is made up of motor, oil pump, oil cylinder, push rod, motor is connected with oil pump, the output oil pipe of oil pump is connected on the both sides, front and back of the piston of oil cylinder respectively by the hydraulic control one-way valve, the piston of oil cylinder is connected push rod one end, the other end of push rod is connected with charging apparatus with pull bar by rocking bar, and Electrohydraulic push rod is fixedly mounted on the bearing.
The Electrohydraulic push rod of above-mentioned coke dry-quenching loading device, described oil pump are that clockwise and anticlockwise drives the bidirectional hydraulic oil pump, and the piston both sides of oil cylinder also have drain mast to be connected with oil sump.
Adopt the Electrohydraulic push rod of the coke dry-quenching loading device of this structure, motor drives the positive and negative pressure oil output of bidirectional hydraulic oil pump by clockwise and anticlockwise, deliver to oil cylinder through the hydraulic control one-way valve, realize the to-and-fro motion of piston and push rod, realize coming and going straight line motion thereby drive charging apparatus.The work of the utlity model has operates steadily, not fragile, long service life, safe and reliable, equipment and maintenance cost is low, can satisfy and optimize the advantage of dry quenching manufacturing technique requirent, can substitute the electronic cylinder drive unit of present use.
