Abstract
A variable-diameter wire rope roller wheel belongs to the machine manufacturing technical field and consists of a wheel body and a wire rope, wherein, the outside diameter of the wheel body is made into a shape of unequal diameter, i.e. the diameter of the middle part of the wheel body is big, while the diameters of both ends of the wheel body are small; conical variable-diameter parts are arranged between the part of big diameter and the parts of small diameters; the shape of the wheel body is similar to that of a spindle; the wheel body is provided with a continuous helical groove and the wire rope is winded on the wheel body along the helical groove. During operation, a motor rotates at constant speed; meanwhile, due to the variable-diameter shape of the wheel body, the linear velocity of the wire rope which becomes faster and reaches the maximum speed and uniform motion at the middle part and then becomes slower so as to complete lifting process. With small space usage, a simple structure, safe and stable operation and low cost, the utility model is particularly suitable for low-speed miniature elevator used in low-rise buildings.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, is a kind of steel rope roller of reusing.
Background technology
Existing steel rope roller is made of wheel body and steel rope, and wheel body is isometrical column, and steel rope is wrapped on the wheel body.Wheel body connects the output shaft of motor during work, and the steel rope termination connects weight, and the driven by motor wheel body rotates, and unrolls or discharges steel rope, lifting weight.Because wheel body is isometrical column, the speed equalization of weight motion, and some weight liftings need variable-speed motion, lifting as elevator, need slowly in the start-stop stage, existing solution is mechanical means realizations such as employing governor, or adopts electrical equipment methods such as frequency converter, variable-frequency motor to realize, it is bigger to take up room for small-sized elevator, and cost is also higher.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of take up room little, and the low taper rope roller of productive costs.
The scheme of the utility model technical solution problem is that the external diameter of wheel body is made not isometrical shape, the middle part diameter of wheel body is big, the two ends diameter is little, between major diameter part and the small diameter portion cone shape reduced diameter portion is arranged, the shape of wheel body is similar to spindle, a continuous spiral grooves is arranged on the wheel body, steel rope along spiral grooves on wheel body.During work, motor at the uniform velocity rotates, because the reducing shape of wheel body, the linear velocity of steel rope is by accelerating slowly, and quick and uniform movement by slack-off soon, is finished lifting process at interlude.
The utility model takes up room little, and is simple in structure, safe in operation, stable, and cost is low, is particularly suitable for few layer of low-speed small elevator and uses.
Description of drawings:
Fig. 1 is the utility model scheme drawing.
The specific embodiment:
The utility model is made of wheel body 1 and steel rope 2, the external diameter of wheel body 1 is not isometrical shape, the middle part diameter of wheel body 1 is big, the two ends diameter is little, between major diameter part and the small diameter portion cone shape reduced diameter portion is arranged, the shape of wheel body 1 is similar to spindle, and a continuous spiral grooves 3 is arranged on the wheel body 1, and steel rope 2 is along spiral grooves 3 around wheel body on 1.
Claims (1)
1. taper rope roller, constitute by wheel body and steel rope, it is characterized in that: the external diameter of wheel body is not isometrical shape, the middle part diameter of wheel body is big, the two ends diameter is little, between major diameter part and the small diameter portion cone shape reduced diameter portion is arranged, a continuous spiral grooves is arranged on the wheel body, steel rope along spiral grooves on wheel body.
