CN202028217U - Suspension cage device suspended by linear ball bearings - Google Patents

Abstract

The utility model provides a suspension cage device suspended by ball linear bearings. The suspension cage device is characterized in that a left side hoisting winch reel, a right side hoisting winch reel and the hoisting winch unit which are connected and seated on the rear side of a machine frame constitute a winching power device of the suspension cage device; a linear ball bearing is respectively arranged at the left end and the right end of the front side of the machine frame, and a steel wire steering wheel arranged on each linear ball bearing is used for overcoming the trembling phenomenon of the hoisting suspension cage; the other end heads of the front side steel wires are wound around the steel wire steering wheels respectively and then are fixed on the hoisting winch reels; and the other end heads of the rear side steel wires are fixedly connected with the hoisting winch reels directly; therefore, the effect that four winching steel wires drive the hoisting suspension cage to hoist and lower steadily is achieved.

Description

Cage device with the suspension of ball linear bearing

Technical field

The utility model relates to a kind of stage setting, and relates more specifically to a kind of cage device that hangs with the ball linear bearing.

Background technology

In stage performance, for reflect the performer go up to the air and skyborne performance for the purpose of, often need use the cage device.Traditional cage device is with steel wire rope cage to be suspended in midair, and with the elevator facility wire rope roll is got up, or loosens steel wire rope and realize the liter of cage device or fall.Because the letter of lifting elevator is provided with grooving, but the orderly elevator of hoisting rope wiring groove during elevator and rise or fall, steel wire rope produces translational motion simultaneously, but prior art can not overcome produce because of translational motion make the lifting of cage device the time jitter phenomenon arranged, the forfeiture stationarity influences performing effect.

Summary of the invention

The objective of the invention is to be to provide the cage device of the steady lifting of a kind of energy.

The utility model is realized by following design:

A kind of cage device that hangs with the ball linear bearing, comprise frame, the letter of lifting elevator and lift winch group, bearing block, shaft coupling, hoisting rope, steel wire rope deflecting roller, linear ball bearing seat and linear ball bearing fixed mount, elevator cage, its:

In the left end place of frame rear side, the letter of right side lifting elevator is connected with the lift winch group of seat in frame rear side right-hand member place the letter of left side lifting elevator by the bearing block seat, and left and right side lifting elevator general regulations link to each other by shaft coupling;

Place, left and right two ends in the frame front side respectively establishes a linear ball bearing fixed mount, and described steel wire rope deflecting roller then passes through the linear ball bearing seat in the linear ball bearing fixed mount;

Respectively at the left front end and the left back end of elevator cage, and right front ends and right rear end a hoisting rope respectively is set everywhere;

Be located at another termination of the front side hoisting rope at described left front end or right front ends place, walk around a left side or right-hand member steel wire rope deflecting roller respectively after, be fixed in the lifting elevator letter on a left side or right side;

Be located at another termination of the rear side hoisting rope at described left back end or right rear end place, the simple Joint of lifting elevator then direct respectively and a left side or right side.

Effect of the present utility model is clearly:

Four steel wire ropes of suspention cage, while lifting under the elevator of a left side and the lifting elevator letter on right side, and be fixed in the front end steel wire rope in the letter of same lifting elevator, when walking around the steel wire rope deflecting roller, because described steel wire rope deflecting roller is under the compensating action of the translational motion that linear ball bearing produces, make two synchronous translations of steel wire rope of being fixed in the letter of same lifting elevator, overcome the jitter phenomenon of cage, realized intended purposes of the present utility model.

The specific embodiment

Below in conjunction with drawings and embodiments, the utility model is described in further detail:

A kind of cage device that hangs with the ball linear bearing, comprise frame 7, the letter 2 of lifting elevator and lift winch group 1, bearing block 6, shaft coupling 5, hoisting rope, steel wire rope deflecting roller 8,9 of linear ball bearings and linear ball bearing fixed mount 10, elevator cage 11, its:

As illustrated in fig. 1 and 2, left side lifting elevator letter 2 by 6 of bearing blocks in the left end place of frame 7 rear sides, right side lifting elevator letter 2 is connected with the lift winch group 1 of seat in frame 7 rear side right-hand member places, 2 of left and right side lifting elevator letters are continuous by shaft coupling 5, form the elevator power set of present embodiment.

As shown in Figure 2, the place, left and right two ends in frame 7 front sides respectively establishes a linear ball bearing fixed mount 10,8 of described steel wire rope deflecting rollers by 9 of linear ball bearings in linear ball bearing fixed mount 10.Described steel wire rope deflecting roller 8, as shown in Figure 3, can be by the effect of linear ball bearing 9, produce translational motion, thereby reach and allow the front side hoisting rope 4 of walking around steel wire rope deflecting roller 8, when carrying out lifting, can carry out translation in a small amount, reach the purpose that is synchronized with the movement with rear side hoisting rope 3, overcome the phenomenon of elevator cage 11 shakes.

As shown in figs. 1 and 4, respectively at the left front end and the left back end of elevator cage 11, and right front ends and right rear end a hoisting rope 4 and 3 respectively are set everywhere.

Shown in Figure 4 and 5, be located at another termination of the front side hoisting rope 4 at described left front end or right front ends place, walk around a left side or right-hand member steel wire rope deflecting roller 8 respectively after, be fixed in the lifting elevator letter 2 on a left side or right side; Be located at another termination of the rear side hoisting rope 3 at described left back end or right rear end place, simple 2 Joints of lifting elevator then direct respectively and a left side or right side.Thereby realize the front side hoisting rope 4 and the rear side hoisting rope 3 of homonymy, can synchronization lifting; When the lifting elevator letter 2 on a left side or right side was turned round synchronously, then four hoisting ropes drove elevator cage 11 steady liftings.
