Referring to fig. 1-6, a long-stroke narrow-working-condition bridge crane steel wire rope anti-twisting device comprises a guide frame 10, connecting screws 20 and clamping plates 30, wherein the guide frame 10 comprises a mounting section 11 in the middle and inclined support sections 12 respectively positioned at two ends of the mounting section 11, the inclined support sections 12 and the mounting section 11 form included angles matched with inclined planes at two sides of a nut column 50, guide rollers are arranged at the ends of the inclined support sections 12 at two sides, the guide frame 10 is provided with two guide frames 10, the two guide frames 10 are arranged in a state that the guide rollers are far away from each other, the two connecting screws 20 are arranged on the mounting section 11 of the guide frame 10, and the two clamping plates 30 are arranged on the connecting screws 20 positioned between the guide frames 10 at two sides. The inclined support section 12 and the installation section 11 form an included angle matched with inclined planes at two sides of the nut column 50, and guide rollers are installed at the end parts of the inclined support sections 12 at two sides, so that only the guide rollers of the guide frame 10 can be in contact with the nut column 50, and the guide rollers are positioned on the inclined planes of the nut columns 50 at two sides, so that the whole anti-twisting device cannot rotate between the nut columns 50 at two sides and only can move up and down, after the guide frames 10 at two sides are installed on a pulley block of a lifting hook through the clamping plate 30 and the connecting screw 20, the rotary lifting of lifting equipment under the long-stroke narrow working condition can be realized, a bridge crane steel wire rope is not wound, and the movable pulley block and the lifted equipment do not collide with the nut column.

Specifically, referring to fig. 2 and 3, the guide roller comprises a wheel seat 13, a mandrel 14 and a roller 15, wherein the roller 15 is arranged on the wheel seat 13 through the mandrel 14, and the wheel seat is fixedly connected with the inclined support section, so that the structure is simple. The roller 15 may be carbon steel, stainless steel or a stronger plastic.

Referring to fig. 2, the mounting section 11 of the guide frame 10 is provided with two mounting holes 16 for mounting the coupling screw 20 in a length direction, so that the coupling screw 20 can be easily mounted.

Specifically, referring to fig. 1, the connecting screw 20 is a double-ended screw 21, and two nuts 22 are respectively mounted on threads at two ends of the double-ended screw 21.

The two ends of the clamping plate 30 are respectively provided with a hole corresponding to the mounting hole 16 of the guide frame 10, the connecting screw rod 20 penetrates through the mounting hole 16 after penetrating through the hole of the clamping plate 30, and the two nuts 22 at each end of the connecting screw rod 20 are respectively positioned at the outer side of the guide frame 10 and the inner side of the clamping plate 30.
