Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] The invention provides a hoist, such as Figures 1 to 10 As shown, it includes a frame 1, a winding rope assembly 2, a tight rope assembly 3, a lifting rope 4, and a plurality of adjustable support feet 5. The frame 1 includes two fixing plates 11, a plurality of connecting rods 12, and two fixing plates 11 They are arranged parallel to each other and at intervals; a plurality of connecting rods 12 are arranged parallel to each other, and the two ends of the connecting rods 12 are respectively connected to two fixing plates 11 . Preferably, the number of connecting rods 12 is six, three con...

Abstract

The invention discloses a hoisting machine. The hoisting machine comprises a frame, a rope rolling assembly, a rope fastening assembly and a hoisting rope. The rope rolling assembly comprises a rolling cylinder and a first driving unit, the rolling cylinder is rotatably connected to the frame, and the first driving unit is connected to the rolling cylinder and used for driving the rolling cylinderto rotate around the axis of the rolling cylinder; the rope fastening assembly comprises a supporting base unit, a rope fastening wheel, rope press wheels and a second driving unit, the supporting base unit is movably connected to the frame in the axial direction of the rolling cylinder, the rope fastening wheel is rotatably connected to the supporting base unit, the rope press wheels are rotatably connected to the supporting base unit, an output shaft of the second driving unit is connected with the rope fastening wheel, and the second driving unit is used for driving the rope fastening wheel to rotate along the axis of the rope fastening wheel; the second driving unit is arranged on the supporting base unit, and the output shaft of the second driving unit is connected with the rope fastening wheel. One end of the hoisting rope winds the rolling cylinder, the other end of the hoisting rope slidably penetrates through the space between the rope press wheels and the rope fastening wheel, and the hoisting rope abuts against the rope fastening wheel and the rope press wheels. According to the hoisting machine, the situation can be effectively avoided that when the hoisting machine carries on rope collection and release, a steel wire rope looses.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a winch. Background technique [0002] The hoist can be used for lifting heavy objects alone, and can also be used as a component of machinery such as lifting, road construction and mine hoisting. It is widely used because of its simple operation, large amount of rope winding, and convenient displacement. It is mainly used in construction and water conservancy projects. , Forestry, mines, wharves, etc. material lifting or flat dragging. However, there are defects in the existing hoist. During the no-load rope receiving and unloading process of the hoist, the weight of the spreader may be too light or the swing angle of the wire rope may be too large, and the tension of the wire rope may be too small, thereby affecting the tightness of the wire rope on the drum. The phenomenon of loose winding occurs, resulting in rope biting, rope skipping, and the formation of multi-layer wind...
