Description
Technical field
The lifting mechanism of crane for coke pot described in the utility model belongs to lifting transportation, coking machinery.
Background technology
At present, dry quenching is indispensable link in the coking process, and it has the dust of minimizing and CO
2Discharging, improve coke strenth, reduce the blast furnace coking, reclaim heat energy and produce advantages such as steam-electric power.Dry quenching at home and abroad coal chemical enterprise has obtained widespread use.
Crane for coke pot is one of key equipment of dry quenching system, and main effect is that red Jiao is transported to the dried groove that puts out.The reliable and stable operation of crane for coke pot is the basic assurance of dry quenching system normal operation, and reliability, ease for use require very high.
Crane for coke pot is programme controlled weight-lifting equipment, and its work is frequent, and lifting velocity is higher.Traditional crane for coke pot lifting mechanism is made up of planetary reduction gear, two (four) platform electrical motors, two groups of double crosslinking drums, high speed shaft drg, coupler.Its planetary reduction gear only has two output axle heads, two or four input shaft ends, and reel is not provided with sure brake.
Such lifting mechanism has a lot of defectives: if planetary reduction gear planet bag damages, load is out of control will fall; Electrical motor, reel group are arranged in the retarder both sides, and mechanism's integral body is not symmetric arrangement, whole unbalance stress; Load hoists in the process, and wire rope rope has horizontal component of force, and center of gravity is with the skew of height change occurred level, and the process horizontal direction of hoisting has impact; Under the same conditions, adopt two groups of double crosslinking drums to strengthen the structure of single reel group, be unfavorable for repair and maintenance.At existing problem in the above-mentioned prior art, the lifting mechanism of a kind of later-model crane for coke pot of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is the lifting mechanism of a kind of later-model crane for coke pot of research and design, thereby solves the whole unbalance stress of mechanism that existing lifting mechanism messenger chain exists; Load hoists in the process, and horizontal force is arranged, and center of gravity is offset with the height change occurred level; Reel structure is big, is unfavorable for problems such as repair and maintenance.The lifting mechanism of crane for coke pot described in the utility model is made up of simply connected reel group, planetary reduction gear, electrical motor, coupler, drg, fixed pulley group, sure brake.Its structure is to be installed in four input shaft ends and four output axle heads that the planetary reduction gear on the trolley frame has symmetric arrangement.Four input shafts are located at the middle part of planetary reduction gear, and are connected with electrical motor respectively by coupler, and drg is housed respectively on the coupler.Four output shafts are located at the both sides, end of planetary reduction gear, are connected with simply connected reel group respectively, and sure brake acts directly on the reel edge of simply connected reel group.The fixed pulley group is installed in the offside of simply connected reel group.Four output shafts described in the utility model are located at the both sides, end of planetary reduction gear, are connected with four simply connected reel groups respectively, and four sure brakes act directly on the reel edge of simply connected reel group.Four fixed pulley groups are installed in the offside of simply connected reel group.
The lifting mechanism of crane for coke pot described in the utility model comprises the planetary reduction gear that hoists, the electrical motor on the input shaft, coupler and drg, the reel group on the output shaft, sure brake, fixed pulley group.The planetary reduction gear that hoists has four input shaft ends of symmetric arrangement, four output axle heads, and electrical motor, simply connected reel group, coupler, drg, fixed pulley group are arranged symmetrically in the retarder both sides, and sure brake acts directly on the reel.Dependence has the planetary reduction gear and the electric control system of speed overlaying function, and when four electrical motors were worked simultaneously, sleeve mechanism had higher lifting velocity; When Dang Yitai, two or three electrical motor et out of orders, but other electrical motor normal operation still, the speed long-play that sleeve mechanism can be lower.Can satisfy the quantity-produced requirement of dry quenching system, have higher reliability and safety.The hoist rope of symmetric arrangement is the horizontal component of force of cancelling out each other, can occurred level skew and impact in the process of hoisting.Fixed pulley group end structure has hydraulic pressure and supports, and it is lax to solve wire rope rope, and the long-time back rope capacity of using changes the problem that can not accurately locate.Advantage with compact conformation, safe and reliable, adjustable height, buffering and overload alarm.
The whole symmetric arrangement of the lifting mechanism of crane for coke pot described in the utility model, the load rectangular distribution; Load hoists in the process, and the wire rope rope horizontal component of force is cancelled out each other, and center of gravity is with not occurred level skew of height change, and horizontal direction is not impacted; Can not have influence on the lifting of load under the situation of the part that hoists electrical motor or its control system generation fault, serious safety misadventure can not take place; In electrical motor replacement cycle long-time, still possess the ability of continuous safety in production, guarantee basic production requirement; Sure brake acts directly on the reel, realizes the emergency braking protection of load, has eliminated potential safety hazard.Sleeve mechanism has higher reliability and safety, satisfies the quantity-produced requirement of dry quenching system.
The ease for use, reliability, the safety that the utlity model has novel structure, improved crane for coke pot.Satisfy the job requirements of crane for coke pot.Have that safe and reliable, load-carrying capacity is big, symmetrical configuration is arranged, stressed advantage such as evenly, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
