Abstract
An assist device used for manned lifting and rotating device of the stage is provided, which comprises a ring fixed on the steel structure, the ring is opened with a position hole used for penetrating the manned traction rope, the upper surface of the ring is provided with a roller unit decreasing the friction, the roller unit comprises a roller seat arranged around the position hole, and the roller is arranged in the roller seat; the lower surface of the ring is equipped with a roller unit that has the same structure with the upper surface, the roller seats of the upper and lower surfaces are alternatively arranged corresponding to the ring, the edges of the upper and lower rollers towards one side of the position hole surround into a rotary limit area of tight drag rope, and the rotary limit area is positioned in the position hole area on the ring. The utility model adds the assist device on decreasing the friction, the roller units are arranged on the upper and lower surfaces of the ring, thus transforming the part of sliding friction between the wire rope and the location hole of the ring into the rolling friction, decreasing the friction loss of the wire rope, and improving the service life of the wire rope.
Description
(1) technical field
The utility model relates to the servicing unit that a kind of stage manned lift whirligig is used, and belongs to the stage machinery device that is exclusively used in arenas.
(2) background technology
At present, existing arenas manned lift device drives manned pull rope (steel wire rope) lifting and rotation by drive unit.In the performance, performer or stage property are being done lifting and are being rotatablely moved in the locating hole of lasso on being arranged in steel construction under the hanging of steel wire rope, produce very big sliding friction between steel wire rope and the locating hole, cause the damage and the fracture of steel wire rope easily.In order to guarantee safety, only way often is exactly change steel rope more, and is both inconvenient, expends cost again.
(3) summary of the invention
The purpose of this utility model is to solve steel wire rope that existing stage manned lift whirligig exists with the locating hole coefficient of friction is big, the easy impaired shortcoming of steel wire rope, the servicing unit that provides a kind of stage manned lift whirligig of the frictional force between a kind of locating hole that can greatly weaken steel wire rope and lasso to use.
For this reason, the utility model is taked following technical scheme:
The servicing unit that a kind of stage manned lift whirligig is used, comprise the lasso that is fixed on the steel construction, have the locating hole that is used to run through manned pull rope on the described lasso, described lasso upper surface is provided with the roller set that reduces to rub, described roller set comprises a plurality of openings of evenly arranging around the outside of locating hole towards " U " of locating hole type roller mount, and roller is installed in the described roller mount by horizontally disposed roller bearing; Described lasso lower surface arrangement has the roller set with the upper surface same structure, the relative lasso of the roller mount of the described upper and lower surface layout that interlaces, described upward bottom roller surrounds the rotary stopper zone of airtight pull rope towards the edge of locating hole one side, described rotary stopper zone is positioned at the locating hole regional extent on the lasso.
The roller set of described lasso upper surface is made up of four rolling.
The roller set of the relative lower surface of roller set of described lasso upper surface 45 degree that interlace arrange, the frontal plane of projection in the rotary stopper zone that surrounds towards the locating hole center of each four rolling is an octagon up and down.
The center of described octagon overlaps with the center of locating hole.
The utility model has the advantages that: 1, increased the servicing unit that reduces to rub, in the lasso upper and lower surface roller set is installed, change the part sliding friction between the locating hole of steel wire rope and lasso (mainly be move up and down time) between steel wire rope and the roller rolling friction at steel wire rope, the friction that has reduced steel wire rope greatly is impaired, has improved the service life of steel wire rope; 2, effectively prolonged the more cycle of change steel rope; 3, reduced use cost.
(4) description of drawings
Fig. 1 is the schematic diagram of stage manned lift rotation;
Fig. 2 is arranged in the roller set schematic diagram of lasso upper surface for the utility model;
Fig. 3 is installed in the side view of the servicing unit on the steel construction for the utility model;
Fig. 4 is the whole schematic top plan view of the utility model.
(5) specific embodiment
With reference to accompanying drawing 1-4, the servicing unit that a kind of stage manned lift whirligig is used, comprise the lasso 1 that is fixed on the steel construction 5, have the locating hole 2 that is used to run through manned pull rope on the described lasso, described lasso upper surface is provided with the roller set that reduces to rub, described roller set comprises four openings evenly arranging around the outside of locating hole towards " U " of locating hole type roller mount 3, and roller 4 is installed in the described roller mount by horizontally disposed roller bearing 7; Described lasso lower surface arrangement has the roller set with the upper surface same structure, the relative lasso of the roller mount of the described upper and lower surface layout that interlaces, described upward bottom roller surrounds the rotary stopper zone 6 of airtight pull rope towards the edge of locating hole one side, described rotary stopper zone is positioned at the locating hole regional extent on the lasso; The roller set of described lasso lower surface is positioned at the installing hole that the steel construction below the lasso is offered.The roller set of described lasso upper surface is made up of four rolling.The roller set of the relative lower surface of roller set of described lasso upper surface 45 degree that interlace arrange, the perspective plane in the rotary stopper zone that surrounds towards the edge of locating hole one side of each four rolling is an octagon up and down.
Because the rotary stopper zone that roller surrounds is positioned at the regional extent of cover circle hole, steel wire rope only can contact with roller, has avoided and the sliding friction of overlapping circle hole, and the friction that has effectively weakened steel wire rope is impaired, has improved service life.
Claims (4)
1. servicing unit that the stage manned lift whirligig is used, comprise the lasso that is fixed on the steel construction, it is characterized in that: have the locating hole that is used to run through manned pull rope on the described lasso, described lasso upper surface is provided with the roller set that reduces to rub, described roller set comprises a plurality of openings of evenly arranging around the outside of locating hole towards " U " of locating hole type roller mount, and roller is installed in the described roller mount by horizontally disposed roller bearing;
Described lasso lower surface arrangement has the roller set with the upper surface same structure, the relative lasso of the roller mount of the described upper and lower surface layout that interlaces, described upward bottom roller surrounds the rotary stopper zone of airtight pull rope towards the locating hole center, described rotary stopper zone is positioned at the locating hole regional extent on the lasso.
