Description

A kind of flybar collision slowing device

Technical field

This utility model relates to field of stage equipment, a kind of flybar collision slowing device.

Background technology

Flybar is the equipment that in stage performing art machinery, usage frequency is the highest, and its major function is to cooperate with the stage story of a play or opera, suspended lamp, stage property, sound equipment, setting, or little performance stand etc..

The safe operation of flybar, one is intended to counterweight balance, two are intended to prevent overload, three is to prevent from suspension rod from running roof fall (to reach high limit position, hoist engine still runs) and suspension rod run the de-end and (reach stage table top, hoist engine still runs), four is to prevent stall from running.Practice have shown that, when the problems referred to above occur, it is possible to cause the collision between suspension rod, so develop into pound lamp electric leakage, scorch fire, stage property pounds platform, curtain is wound around, wears the stage security incidents such as ceiling down.Therefore, flybar collision isolation is the important technology requirement of stage safety.

Owing to modern play purpose story tempo increase and plot conflicts strengthen, corresponding setting, light, stage property scale increasing, this cause flybar level more and more closeer, suspension rod spacing is more and more less, and suspension rod lifting is more and more frequent.Owing to the counterweight of flybar differs, formed when suspension rod lifts and swing and twisting, cause the collision accident between suspension rod, so collision isolation and collision isolation damper between suspension rod increasingly become the major issue that stage must take into safely.

But, owing in special equipment is not yet listed stage technique equipment by country, relevant safety monitor does not the most extend to stage technique equipment, and flybar collision isolation technology is equipped the most in a state of nature, so being necessary to research and develop a flybar collision isolation slowing device.

Summary of the invention

The purpose of this utility model is contemplated to overcome above-mentioned weak point of the prior art, it is provided that a kind of flybar collision slowing device, and its simple in construction is easy to use, can be prevented effectively from the rigid collision between suspension rod.

The purpose of this utility model is achieved by the following technical measures: a kind of flybar collision slowing device, it is made up of a pair collision isolation mount, described collision isolation mount includes rubber blanket, light leaf spring, brute spring, inner support and support arm, connected by brute spring between described inner support and support arm, described support arm is connected with curved light leaf spring by the second bolt, adhere to one layer of rubber blanket outside light leaf spring, be interconnected and fixed on suspension rod by two inner supports between paired collision isolation mount.

In technique scheme, described brute spring is helical spring.

This utility model is by 4 layers of technique devices such as hard rubber, light leaf spring, brute spring and supports, it is achieved that the passing in order of function such as energy-absorbing → kinetic energy dissipation → vibration damping → isolation connect, thus thoroughly cut down the impact kinetic energy of suspension rod, vibrate and resonate；By the light plate spring structure of circular arc, it is to avoid the rigid collision of suspension rod；Pass through supporting structure, it is to avoid for the light fixture being suspended on suspension rod, Dao Jie, setting and the collision of little performing stage, thus effectively eliminate and collide the harm for suspension rod, protect stage hanger rod system.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Wherein: 1. inner support, 2. support arm, 3. helical spring, 4. light leaf spring, 5. rubber blanket, 6. the first bolt, 7. the second bolt, 8. suspension rod, be shown as suspension rod cross section in figure.

Detailed description of the invention

Below in conjunction with accompanying drawing, the technical scheme in this utility model is clearly and completely described.

As shown in Figure 1; the present embodiment provides a kind of flybar collision slowing device; it is made up of a pair collision isolation mount; described collision isolation mount includes rubber blanket 5, light leaf spring 4, helical spring 3, inner support 1 and support arm 2; connected by helical spring 3 between described inner support 1 and support arm 2; described support arm 2 is connected with curved light leaf spring 4 by the second bolt 7; one layer of rubber blanket 5 is adhered to outside light leaf spring 4; it is fastened on suspension rod 8 by the first bolt 6 between two inner supports 1 between paired collision isolation mount, forms protection in suspension rod border.The present embodiment device forms the collision of " energy-absorbing-dissipation kinetic energy-vibration damping " composition by 3 layers of elastic construction and slows down structure, forms collision isolation structure by the inside and outside support of rigidity；Collision is slowed down structure and is combined the collision isolation damper device of composition complex function with collision isolation structure.

In the above-described embodiments, described light leaf spring 4, in circular arc, forms the protection close to 360 degree in suspension rod border after a pair collision isolation mount interconnection is fixing.

When flybar collides, the hard rubber pad 5 being arranged in collision isolation damper device outer end absorbs impact kinetic energy by a certain degree of deformation, reduces the rigid collision between suspension rod；After hard rubber pad 5 deforms, occur that resilience recovers, continue to cut down impact kinetic energy.The double absorption of impact kinetic energy, effectively alleviates and collides the impact for suspension rod.

After suspension rod collision occurs, impact kinetic energy is further transferred on light leaf spring 4.Impact kinetic energy by compressive deformation, is converted into elastic potential energy after experiencing impact kinetic energy by light leaf spring 4, then elastic potential energy is converted into the recovery kinetic energy of Collision-free by recoverable force, and dissipated impact kinetic energy；Meanwhile, arc-shaped light leaf spring 4 structure can effectively prevent suspension rod collision to be wound around.

When the impact kinetic energy not absorbed and dissipate is transmitted on helical spring 3 further, fallen by vibration damping.

Collision isolation mount is fixed on flybar in couples, it is possible to the directly collision between isolation flybar, it is possible to directly absorb and Dissipative Collisions kinetic energy, it is possible to directly slow down crash shock, thus prevent suspension rod rigid collision or winding.

The content not being described in detail in this specification, belongs to prior art known to those skilled in the art.
