Description

Technical Field

[0001] The utility model relates to the technical field of drums, in particular to a wire rope folding drum. Background Technique

[0002] The term "folding drum" is popular in the hoisting industry in China and refers to a form suitable for multi-layer winding of wire ropes introduced from abroad. Since this kind of rope groove is parallel to the flange end face in most sections of the drum circumference and only intersects with the flange end face in a very small section, the rope groove will inevitably show a folding phenomenon, so it is named "folding rope groove".

[0003] When the existing folding drum structure winds the wire rope, the arrangement of the wire rope is not uniform enough, which affects the winding quality. At the same time, when winding the wire rope, it is not convenient to control the winding amount, resulting in corresponding safety accidents. Content of the Utility Model

A supporting plate 12 is arranged on the inner wall of the fixing frame 2. A connecting slide bar 13 is slidably connected inside the supporting plate 12. A fixing frame 14 is arranged at one end of the connecting slide bar 13. A connecting shaft rod is rotatably connected inside the fixing frame 14. A roller 15 is rotatably connected to the outer surface of the connecting shaft rod. A first spring 15 is arranged on the outer surface of the supporting plate 12. A limiting piece is arranged at one end of the first spring 15. The limiting piece is arranged at one end of the connecting slide bar 13. The first spring 15 is sleeved on the outer surface of the connecting slide bar 13. An electric push rod 17 is arranged on the side of the supporting plate 12 away from the first spring 15. A pressure sensor 18 is arranged at the output end of the electric push rod 17. The number of the connecting slide bars 13 is two, and they are symmetric to each other.

[0026] In order to enable this wire rope folding drum to have the effect of facilitating the control of the winding arrangement of the wire rope and improving the winding uniformity, and to enable this wire rope folding drum to have the effect of facilitating the control of the winding amount and improving the use safety, as shown in the attached Figures 1-5As shown in the figure, the present application adopts the following structure. Through the cooperation of the rotating shaft rod 3, output gear 4, connecting gear 5, transmission gear 6, reciprocating lead screw 7, moving plate 8, slider 9, guiding slide bar 10 and insertion hole 11, support plate 12, connecting slide bar 13, fixed frame 14, roller 15, first spring 15, electric push rod 17 and pressure sensor 18, during the use process, one end of the rotating shaft rod 3 is connected to the corresponding motor output shaft, one end of the steel wire rope is passed through the insertion hole 11 of the moving plate 8 and then fixed to the drum body 1. Through the rotation of the motor, the rotating shaft rod 3 is driven to rotate, thereby driving the drum body 1 to rotate, and the steel wire rope is wound around the outer surface of the drum. At the same time, under the action of the output gear 4 and the connecting gear 5, the transmission gear 6 is driven to rotate, thereby driving the reciprocating lead screw 7 to rotate, driving the slider 9 in the moving plate 8 to slide in the spiral chute of the reciprocating lead screw 7, thereby driving the moving plate 8 to slide reciprocally left and right along the guiding slide bar 10, so that the steel wire rope is evenly wound around the outer surface of the drum body 1. When the steel wire rope is wound around the drum body 1, as the winding amount of the steel wire rope gradually increases, the steel wire rope abuts against the roller 15, thereby causing the fixed frame 14 and the connecting slide bar 13 to slide relative to the support plate 12, stretching the first spring 15, making the fixed frame 14 gradually approach the pressure sensor 18. When the pressure sensor 18 is squeezed, a pressure signal is sent, thereby stopping the rotation of the motor, completing the control of the winding amount. At the same time, during use, the position of the pressure sensor 18 can be adjusted by controlling the extension of the electric push rod 17, thereby changing the winding amount of the steel wire rope, enabling this steel wire rope folding drum to have the effect of facilitating the control of the winding arrangement of the steel wire rope and improving the winding uniformity, and enabling this steel wire rope folding drum to have the effect of facilitating the control of the winding amount and improving the use safety.
