Technical Field
The utility model relates to a metallurgical equipment, in particular to a blast furnace skip car wire rope replacing device applicable to iron and steel smelting enterprises.
Background
In the current iron and steel smelting enterprises, the steel wire rope for drawing the iron-making blast furnace skip car is in continuous contact with the head sheave and the winding drum and is abraded, so the steel wire rope needs to be replaced regularly.
The current replacement method is as follows: after the new wire rope is unfolded, 6 workers are required to work simultaneously, and the unfolded wire rope is manually coiled on two forks of a walking forklift. In the process of manually transferring the steel wire rope, the steel wire rope can generate large torsional stress after being coiled, so that the service life of the steel wire rope is influenced, and meanwhile, the steel wire rope is extremely easy to cause serious injury to operating personnel and operating vehicles.
In addition, when the twisted steel wire rope is transferred to a winch machine room for replacement, the new steel wire rope and the old steel wire rope firstly need to be in butt joint welding, then the new steel wire rope needs to be conveyed in a mode of manually transferring relay, and meanwhile, a tractor needs to drag the old steel wire rope from the bottom of the oblique bridge to bring the new steel wire rope into position. In the process of releasing a new rope, because the overlength and the larger mass (the diameter is 38 MM; the length is 165M; and the mass is 2.5T) of each steel wire rope, the operation of 12 persons is required to be successfully completed at present.
The existing manual rope coiling and releasing operation is high in labor intensity and high in operation risk, so that replacement of a skip car steel wire rope is always a key operation project for maintenance work of metallurgical enterprises.
SUMMERY OF THE UTILITY MODEL
The technical task of the utility model is to provide a safe swift blast furnace skip wire rope changes device to the not enough of above prior art.
The technical proposal of the utility model for solving the technical problem is that: the utility model provides a blast furnace skip wire rope changes device which characterized in that: comprises a base, a main motor, a speed reducer, a transmission mechanism, a winding drum, a brake and an electric travelling mechanism; the main motor, the winding drum and the brake are arranged on the base; the transmission mechanism comprises a driving chain wheel, a driven chain wheel and a chain, the main motor is connected with a central hole of the driving chain wheel through a speed reducer, and the driving chain wheel is connected with the driven chain wheel through the chain; the driven chain wheel is coaxially connected with the winding drum, and the brake is coaxially connected with the other end of the winding drum; the winding drum is provided with a partition plate, and a hook is arranged on the drum surface between two end plates of the winding drum and the partition plate; the electric walking mechanism is arranged on the lower part of the base.
The driving chain wheel and the driven chain wheel are double-row roller chain wheels, and two chains are provided.
The hook is a J-shaped hook.
The speed reducer is a cycloidal speed reducer.
The partition board of the winding drum is a hollow board.
Compared with the prior art, the utility model discloses following outstanding beneficial effect has:
1. effectively reduce the injury to operation personnel and working vehicle.
2. Effectively reduce the torsional stress of wire rope in artifical transmission process, alleviate the stress damage of avoiding of wire rope and the damage of colliding with.
3. The operation efficiency is improved, the maintenance time is shortened, the productivity is improved, and the enterprise benefit is increased.
4. Reduce the physical labor of personnel and improve the intrinsic safety of the operation.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention is further described with reference to the drawings and the detailed description.
As shown in fig. 1, the utility model comprises a base 9, a main motor 1, a speed reducer 2, a transmission mechanism, a winding drum, a brake 7 and an electric walking mechanism 8.
The main motor 1, the winding drum and the brake 7 are arranged on the base 9.
In this embodiment, the transmission mechanism includes a driving sprocket 3, a driven sprocket 4 and a chain, and aims to reduce the installation size and the equipment weight. The transmission mechanism can also be in a belt pulley and belt transmission mode. In the optimized scheme, the driving chain wheel 3 and the driven chain wheel 4 are double-row roller chain wheels, and two chains are provided.
The main motor 1 is connected with a center hole of a driving chain wheel 3 through a speed reducer 2, and the driving chain wheel 3 and a driven chain wheel 4 form a chain wheel and chain transmission relationship through a chain. The driven chain wheel 4 is coaxially connected with the winding drum, and the brake 7 is coaxially connected with the other end of the winding drum. And a brake 7 is arranged at the other end of the main shaft of the winding drum, so that the condition that the winding drum loses braking due to accidental breakage of a transmission chain is avoided.
The middle of the winding drum is provided with a partition plate 5, a J-shaped hook 6 is arranged on the drum surface between two end plates of the winding drum and the partition plate 5, and the electric travelling mechanism 8 is arranged on the lower portion of the base 9. In this embodiment, the electric traveling mechanism 8 is specifically a wheel driven by a motor.
The speed reducer 2 is a cycloidal speed reducer 2 and has the advantages of light weight, small volume and large speed ratio.
The baffle 5 of reel is the fretwork board, can alleviate the total mass of equipment.
The operation flow is as follows: after two new steel wire ropes are fully unfolded according to the required length to eliminate stress, one ends of the steel wire ropes are respectively welded with U-shaped hanging rings, one ends of the welded U-shaped hanging rings are respectively hung on J-shaped hooks 6 at two ends of a winding drum to be fixed, a main motor 1 is started to wind the unfolded steel wire ropes on the winding drum, personnel and vehicle injuries caused by the fact that the unfolded steel wire ropes are coiled on a forklift in walking are avoided, and the manual labor intensity of operating personnel is reduced.
The utility model is hoisted to a hoisting room together with the steel wire rope by a crane, and a 380V power supply is connected. Adopt electronic running gear 8 will the utility model discloses adjust to with old skip wire rope centering position.
When changing the operation, new wire rope and old wire rope at first carry out butt joint welding, then start the utility model discloses with the wire rope reel reversal, pull old wire rope from the skew bridge bottom simultaneously and bring the new rope into taking one's place.
As the optimization scheme of the utility model, the main motor 1 and the stopper 7 of this device can adopt wireless remote control mode, can further improve security and work efficiency, also make things convenient for the operator to look over the operation condition of each operation unit.
It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
