Detailed Description

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment.

As shown in fig. 1 to 3, a blast furnace skip rope pulley provided in an embodiment of the present invention includes two installation bases 1 and a rope pulley 2 rotatably disposed on the two installation bases 1, a plurality of rope grooves 3 are disposed in a groove of the rope pulley 2, and the plurality of rope grooves 3 can form an annular structure;

in the existing blast furnace steelmaking production process, the steel wire rope is generally made of 65# steel, the hardness of the rope groove 3 is lower than that of the steel wire rope, so that the abrasion to the steel wire rope can be reduced, and the rope groove 3 can be replaced, so that the steel wire rope can be quickly replaced even if the service life of the rope groove 3 is short;

a fixing rod 5 for fixing the rope groove 3 is arranged on the rope pulley 2, and fixing holes matched with the fixing rod 5 are formed in the rope pulley 2 and the rope groove 3;

as shown in fig. 3, the fixing lever 5 penetrates the sheave 2 and the rope groove 3; when the fixing rod 5 is pulled out, when the end part of the fixing rod 5 moves into the rope groove 3, the self weight of the rope groove 3 presses the end part of the fixing rod 5, so that a shearing force is generated on the fixing rod 5, the fixing rod 5 is bent, and the fixing rod 5 is difficult to take out;

the two mounting seats 1 are respectively provided with a baffle 4, the baffle 4 is provided with a supporting structure, and the supporting structure is abutted against one of the rope grooves 3;

the supporting structure is located at a position where the rope grooves 3 are detached, so that the supporting structure needs to be installed at a position away from the steel wire rope during installation, that is, the supporting structure and the steel wire rope are not in contact with the same rope grooves 3 at the same time, for example, when four rope grooves 3 are formed in the rope sheave 2, only two rope grooves 3 are in contact with the steel wire rope during feeding work, and the supporting structure is arranged at the bottom of the baffle 4 as shown in fig. 3;

the supporting plate is abutted against the rope groove 3, so that when the fixing rod 5 is taken down, the rope groove 3 can not generate shearing force on the fixing rod 5, and the fixing rod 5 is convenient to detach and the bending of the fixing rod 5 is avoided;

the supporting structure comprises a fixed cylinder 6 fixedly connected to the baffle 4, a connecting rod 7 inserted in the fixed cylinder 6 and a rotating wheel 8 rotatably arranged at the end part of the connecting rod 7, and the rotating wheel 8 is abutted against the rope groove 3;

a plurality of spreading structures which correspond to the rope grooves 3 one by one are also arranged in the rope wheel 2; the opening structure comprises a U-shaped frame 11 arranged in the rope wheel 2, and a first inclined sliding block 12 and a second inclined sliding block 13 which are arranged on the U-shaped frame 11;

a return spring 9 connected with the U-shaped frame 11 is arranged in the rope wheel 2;

a through groove 14 is formed in the rope pulley 2, a part of the inclined sliding block I12 is located in the through groove 14, a push rod I15 capable of being inserted into the through groove 14 is arranged on the baffle plate 4, and the push rod I15 is in threaded connection with the baffle plate 4;

a connecting block 16 is fixedly arranged on the connecting rod 7, when the first ejector rod 15 abuts against the first inclined sliding block 12, the U-shaped frame 11 can be pushed to move, and the second inclined sliding block 13 abuts against the connecting block 16 until the rotating wheel 8 is separated from the rope groove 3; a return spring 9 is also arranged in the fixed cylinder 6, one end of the return spring 9 is connected in the fixed cylinder 6, and the other end is connected on the connecting rod 7; under the action of the return spring 9, after the U-shaped frame 11 is reset, the rotating wheel 8 can return to the initial position again;

one of the baffles 4 is inserted with a second ejector rod 21, the other baffle 4 is provided with a yielding hole 22 for yielding the fixed rod 5, the second ejector rod 21 can abut against the fixed rod 5, and the second ejector rod 21 is also sleeved with a return spring 9.

The working process is as follows: when the rope groove 3 needs to be replaced, the rope pulley 2 is rotated to the position where the second ejector rod 21 is opposite to the fixed rod 5, then a part of the fixed rod 5 is ejected out by knocking the end part of the second ejector rod 21, finally the fixed rod 5 is pulled out from the abdicating hole 22, then the first ejector rod 15 is screwed, so that the end part of the first ejector rod 15 is abutted against the first inclined slider 12, the U-shaped frame 11 is pushed to move, the second inclined slider 13 on the U-shaped frame 11 is abutted against the connecting block 16, the two rotating wheels 8 move back to back, namely the rotating wheels 8 are not abutted against the rope groove 3, at the moment, the rope groove 3 falls under the action of gravity, then the new rope groove 3 is mounted, the fixed rod 5 is inserted again to be fixed, finally the first ejector rod 15 is screwed out of the through groove 14, and then the rest of the rope grooves 3 can be replaced according to the steps.
