The pulley support is characterized by comprising a central shaft, wherein two ends of the central shaft are erected on two parallel pulley supports respectively, a plurality of rotatable pulleys are uniformly arranged on the central shaft, a pressing wheel shaft parallel to the central shaft is further arranged on the pulley support, a plurality of rotatable pressing wheels for preventing pull ropes from falling off are arranged on the pressing wheel shaft, and the pressing wheels and the pulleys are arranged in a one-to-one correspondence manner. The utility model discloses a set up the pinch roller in one side of pulley, compress tightly the stay cord in the recess of pulley, solved the problem that the stay cord drops from the pulley, increased the security that the pulley used.
Description
Technical Field
The utility model relates to a prevent falling rope pulley belongs to mechanical equipment technical field.
Background
The pulley is a round wheel which can rotate around a central shaft, the circumferential surface of the round wheel is provided with a groove, a pull rope is wound in the groove, any one end of the two ends of the pull rope is pulled by force, the round wheel can be driven to rotate around the central shaft by the friction force between the pull rope and the round wheel, the pulley is divided into a fixed pulley and a movable pulley according to whether the position of the central shaft of the pulley moves, the central shaft of the fixed pulley is fixed, the central shaft of the movable pulley can move, the pulley is mainly used for changing the direction of force, the movable pulley is mainly used for changing the magnitude of the force, the fixed pulley and the movable pulley are assembled together to form a pulley block, and the pulley block; the pulley and the pulley block are widely applied to machinery, electromechanics, engineering construction, amusement places and the like, under normal conditions, the stress direction of the stay rope on the pulley is orthogonal to the central axis of the pulley, and when the stress direction of the stay rope installed in the pulley or the pulley block is not orthogonal to the central axis of the pulley, and is stressed greatly or is stressed unevenly, the stay rope is easy to fall off from the groove, so that safety accidents are caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, can effectively prevent falling rope pulley that the stay cord drops.
In order to achieve the above object, the utility model adopts the following technical scheme:
the rope falling prevention pulley comprises a central shaft, wherein two ends of the central shaft are respectively erected on two parallel pulley supports, a plurality of rotatable pulleys are uniformly arranged on the central shaft, a pressing wheel shaft parallel to the central shaft is further arranged on the pulley supports, a plurality of rotatable pressing wheels for preventing a pull rope from falling off are arranged on the pressing wheel shaft, and the pressing wheels and the pulleys are arranged in a one-to-one correspondence manner.
The utility model discloses a further improvement lies in: grooves for containing pull ropes are formed in the outer circumferences of the pulleys and the pressing wheel, and the diameter of each groove of the pressing wheel is larger than that of each pull rope.
The utility model discloses a further improvement lies in: the outer diameter of the pinch roller is smaller than that of the pulley.
The utility model discloses a further improvement lies in: the pulley is mounted on the central shaft through a bearing.
due to the adoption of the technical scheme, the utility model discloses the technological progress who gains is:
The utility model discloses a set up the pinch roller in one side of pulley, compress tightly the stay cord in the recess of pulley, solved the problem that the stay cord drops from the pulley, increased the security that the pulley used.
Drawings
Fig. 1 is a schematic perspective view of the present invention.
wherein: 1. pulley support 2, pinch roller axle 3, pinch roller 4, pulley 5, center pin.
The present invention will be described in further detail with reference to the following drawings and examples:
The rope falling prevention pulley comprises two pulley supports 1 which are parallel to each other, as shown in figure 1, a central shaft 5 is erected on the two pulley supports 1, a plurality of rotatable pulleys 4 are uniformly arranged on the central shaft 5, and the pulleys 4 are arranged on the central shaft 5 through bearings; the pulley support 1 is also provided with a pinch roller shaft 2 parallel to the central shaft 5, the pinch roller shaft 2 is provided with a plurality of rotatable pinch rollers 3, the pinch rollers 3 and the pulleys 4 are arranged in a one-to-one correspondence manner, and the outer diameters of the pinch rollers 3 are smaller than the outer diameters of the pulleys 4.
The outer circumferences of the pulley 4 and the pressing wheel 3 are respectively provided with a groove for accommodating the pull rope, the diameter of the groove of the pressing wheel 3 is larger than that of the pull rope, the pressing wheel 3 presses the pull rope into the groove on the outer circumference of the pulley 4, and the pull rope can be effectively prevented from falling off from the groove of the pulley 4.
