Description

Technical Field

[0001] The utility model belongs to the technical field of winch hoists, and in particular relates to a winch hoist. Background Art

[0002] A winch hoist is a device used to lift and move heavy objects, usually composed of a motor, gearbox, drum, wire rope and other components. It can realize vertical transportation of goods by winding wire rope or chain, improving work efficiency and safety. Winch hoists are widely used in construction sites, ports, factories and other places, providing convenience for lifting, handling and other operations.

[0003] The existing gate hoist uses a roller rod to curl and reel the wire rope. During the curling process, the wire rope will be entangled and knotted, making it impossible to release it completely when it is placed later. At the same time, the surface of the wire rope will be squeezed and folded, causing indentations. After long-term use, it will break, making the later use dangerous, thus affecting the later use of the wire rope. Utility Model Content

[0025] Example

[0026] See also Figure 1-5 , the technical solution provided by this embodiment is as follows:

[0027] A winch hoist comprises: a protective shell 1, a rotating shaft 2 is rotatably connected inside the protective shell 1, a winding roller 3 is fixedly connected to the surface of the rotating shaft 2, a steel wire connecting rope 4 is wound around the surface of the winding roller 3, a stretching mechanism 7 for stretching and winding the steel wire connecting rope 4 is installed inside the protective shell 1, a driving mechanism 5 for driving the rotating shaft 2 and the stretching mechanism 7 to operate at the same time is installed on the surface of the protective shell 1, and a control panel 6 is installed on the top of the protective shell 1.

[0028] In a specific embodiment of the utility model, when the driving mechanism 5 is started, the rotating shaft 2 can be driven to rotate, and the rotation of the rotating shaft 2 drives the winding roller 3 to rotate and drives the wire connecting rope 4 to be wound. At the same time, the driving mechanism 5 will drive the stretching mechanism 7 to work. At this time, under the action of the stretching mechanism 7, the wire connecting rope 4 is stretched and wound flatly on the surface of the winding roller 3, thereby reducing the entanglement of the wire connecting rope 4 and causing knots.

[0029] Specifically, the stretching mechanism 7 includes a reciprocating screw rod 701 rotatably connected to the inside of the protective shell 1, the surface of the reciprocating screw rod 701 is threadedly connected to an internal thread block 702, the surface of the internal thread block 702 is rotatably connected to two rolling wheels 703, and the wire connecting rope 4 is arranged on the inner side opposite to the two rolling wheels 703. The stretching mechanism 7 also includes a limiting rail 704 installed inside the protective shell 1, the surface of the limiting rail 704 is slidably connected to a moving slider 705, and the moving slider 705 is fixedly connected to the surface of the internal thread block 702.

[0030] In a specific embodiment of the utility model, when the reciprocating screw rod 701 rotates, it drives the internal thread block 702 to move back and forth. The movement of the internal thread block 702 drives the two rolling wheels 703 to move, thereby stretching the wire connecting rope 4. When the internal thread block 702 moves, it drives the moving slider 705 to move on the surface of the limiting rail 704, thereby increasing the stability of the internal thread block 702 when moving.

[0031] Specifically, the driving mechanism 5 includes a mounting plate 501 installed on the surface of the protective shell 1, one side of the mounting plate 501 is rotatably connected to a first pulley 503, and the first pulley 503 is fixedly connected to the rotating shaft 2, a servo motor 502 is installed on the other side of the mounting plate 501, and the output shaft of the servo motor 502 is fixedly connected to one end of the rotating shaft 2, and a second pulley 505 is fixedly connected to the surface of the reciprocating screw rod 701, the second pulley 505 is rotatably connected to the first pulley 503 through a transmission belt 504, the first pulley 503 and the second pulley 505 have the same size, and the reciprocating screw rod 701 is located below the rotating shaft 2.

[0032] In a specific embodiment of the utility model, the output shaft of the servo motor 502 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the first pulley 503 to rotate while rotating. At this time, the reciprocating screw rod 701 is driven to rotate under the action of the transmission belt 504 and the second pulley 505. By setting the size of the first pulley 503 and the second pulley 505, the rotating shaft 2 and the reciprocating screw rod 701 rotate synchronously, thereby facilitating the smooth winding of the wire connecting rope 4.

[0033] Specifically, the control panel 6 is electrically connected to the servo motor 502 .

[0034] In a specific embodiment of the present invention, the control panel 6 is electrically connected to the servo motor 502 , so that the control panel 6 can control the servo motor 502 .

[0036] In a specific embodiment of the present utility model, the limiting slide groove 8 is provided to facilitate limiting the moving trajectory of the steel wire connecting rope 4, while reducing the probability of curling of the steel wire connecting rope 4 when winding.

[0037] Working principle: when it is necessary to reel in the wire connecting rope 4, start the servo motor 502, and the output shaft of the servo motor 502 drives the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 drives the winding roller 3 to rotate and drives the wire connecting rope 4 to reel in. The rotation of the rotating shaft 2 drives the first pulley 503 to rotate at the same time. At this time, under the action of the transmission belt 504 and the second pulley 505, the reciprocating screw rod 701 is driven to rotate. When the reciprocating screw rod 701 rotates, it drives the internal thread block 702 to move back and forth. The movement of the internal thread block 702 drives the two rolling wheels 703 to move. When the internal thread block 702 moves, it drives the moving slider 705 to move on the surface of the limit rail 704, thereby increasing the stability of the internal thread block 702 when moving, thereby stretching the wire connecting rope 4. At this time, under the action of the stretching mechanism 7, the wire connecting rope 4 is stretched and wound flatly on the surface of the winding roller 3.
