Abstract
The utility model discloses a tilting metallurgical furnace door lifting device. The device comprises a furnace door, anchor chain rigging, a fixed pulley, a steel wire rope, and a hoist. The fixed pulley is arranged in the top part of a furnace body. The top part of the furnace body is further provided with the hoist. The steel wire rope of the hoist penetrates through the fixed pulley and is fastened with one end of each of the two strips of anchor chain rigging via a steel wire rope clamp. The other end of each the anchor chain rigging is connected with the furnace door. A drum shaft end of the hoist is provided with a stroke limiting controller. The lifting of the furnace door in a flame area employs the anchor chain rigging and the lifting operation of the furnace door is controlled electrically via the forward and backward rotation of a motor of the hoist, thereby enabling the main components of the lifting device to be away from a high-temperature radiation area, improving the device work and maintenance environment, and reducing the faults of related devices of the furnace door. The stroke limiting controller arranged in the drum shaft end of the hoist is capable of controlling the lifting stroke of the furnace door. The tilting metallurgical furnace door lifting device is simple in structure, reduced in production cost, and convenient to operate and maintain.
Description
Technical field
The utility model relates to industry metallurgy field of mechanical technique, specifically a kind of tilting-type metallurgical furnace fire door lifting device.
Background technology
The design of tilting-type metallurgical furnace fire door hoisting mechanism, at fire door peripheral position, mainly contains hydraulic drive and the electric chain kind of drive, and single unit system is fixed on the furnace shell of fire door periphery, the synchronous rotary along with the rotation of body of heater.Because the flame temperature of metallurgical furnace fire door ejection can be up to more than 1200 ℃, so be easy to motor, conduit under fluid pressure, rope and the components and parts of scaling loss furnace door lifting device, Frequent Troubles, cause production operation continuously, after furnacing door lifting mechanism breaks down, usually need workman under more than 700 ℃ hot environments, to carry out Maintenance and Repair work, operating condition is severe.
Utility model content
The purpose of this utility model is to provide a kind of tilting-type metallurgical furnace fire door lifting device, to solve the easy scaling loss of motor, conduit under fluid pressure, rope and components and parts of tilting-type metallurgical furnace fire door lifting device, and the severe problem of condition of work during Maintenance and Repair operation.
As follows for solving the problems of the technologies described above the technical scheme that the utility model takes:
A kind of tilting-type metallurgical furnace fire door lifting device, it comprises fire door, fixed pulley, hoist engine, steel wire rope, article two, anchor chain rigging, described fixed pulley is arranged on body of heater top near one end of described fire door, one end at described body of heater top away from fire door is provided with described hoist engine, the reel axle head of described hoist engine is provided with controller for stroke limit, described hoist engine is connected with one end of described steel wire rope, fixed pulley described in described steel wire penetrating, the other end termination of described steel wire rope is provided with wire line shoe, one end locking of described wire line shoe and described anchor chain rigging, the other end of described anchor chain rigging is connected with described fire door.
By use of the present utility model, fire door is used anchor chain rigging in the lifting of flame region, the lifting operation of the electronic control fire door of positive and negative rotation by hoist engine motor, make lifting device main parts size away from hyperthermia radiation region, the operation of equipment and maintenance environment improve, and have reduced the relevant device fault of fire door; Controller for stroke limit can be controlled the lift stroke of fire door.The utility model is simple in structure, and it is convenient to control, easy to maintenance, has reduced production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of tilting-type metallurgical furnace fire door lifting device;
Fig. 2 is the side view of structural representation shown in Fig. 1.
In accompanying drawing: 1, metallurgical furnace body, 2, fire door, 3, fixed pulley, 4, steel wire rope, 5, controller for stroke limit, 6, hoist engine, 7, anchor chain rigging, 8, steel wire rope wire clips.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As Fig. 1, a kind of tilting-type metallurgical furnace fire door lifting device shown in Fig. 2, it comprises fire door 2, fixed pulley 3, hoist engine 6, steel wire rope 4, article two, anchor chain rigging 7, fixed pulley 3 is arranged on body of heater 1 top near one end of fire door 2, one end at body of heater 1 top away from fire door is provided with hoist engine 6, the reel axle head of hoist engine 6 is provided with controller for stroke limit 5, hoist engine 6 is connected with one end of steel wire rope 4, steel wire rope 4 is through fixed pulley 3, the other end termination of steel wire rope 4 is provided with wire line shoe 8, wire line shoe 8 is locked with one end of anchor chain rigging 7, the other end of anchor chain rigging 7 is connected with fire door 2.
The length of anchor chain rigging 7 is greater than the maximum height of fire door jet flames.
The course of work of the present utility model is: when fire door 2 need to promote, start hoist engine 6, hoist engine 6 forward rotation, steel wire rope 4 tensionings, steel wire rope 4 pulls anchor chain rigging 7 to move to furnace roof direction, fire door 2 upwards promotes under the drive of anchor chain rigging 7, and the height that fire door 2 promotes is controlled according to the stroke setting in advance by journey controller 5; When fire door 2 needs reset closed, start hoist engine 6, hoist engine 6 rotates backward, and steel wire rope 4 is lax, and fire door 2 moves downward, and the stroke that fire door 2 declines is controlled by journey controller 5, and then fire door 2 resets are closed.
