Detailed ways

The utility model will be further described below with reference to the accompanying drawings and embodiments.

With the increasingly rich cultural life, people have higher and higher requirements for stage effects in performances. In modern stage design, the stage is an important part of the performance space. In order to create a lively and lively three-dimensional performance effect, many machines on the stage need to be mounted on steel wires to guide the movement of equipment such as spotlights and cameras to its place. The best position is to assist the light and shadow effect of the stage, so the application of the steel wire becomes more and more frequent. However, the guiding direction of the steel wire changes with the displacement of the equipment during the use of the general steel wire. The steel wire needs to be retracted and released to control the extension angle of the steel wire. , At this time, traction machine traction is required, but generally the traction machine is set at the end of the wire, so the guiding efficiency is low and the effect is poor, and only one end of the wire can be controlled, and the simultaneous retraction control of both ends cannot be realized. .

Embodiment 1: As shown in Figures 1 to 3, it is only one of the embodiments of the present utility model, a stage wire guide device, comprising wire 9, a first guide roller 1, a second guide roller 2, and a The winding portion 3 between the first guide roller 1 and the second guide roller 2, the winding portion 3 includes a first winding roller 31 near the first guide roller 1 and a second guide roller near the 2, the first rotating shaft 311 of the first winding roller 31 is connected with the second rotating shaft 321 of the second winding The rotating column 34, the end of the rotating column 34 is provided with a driver 341 for driving the rotating column 34 to rotate, the winding direction of the wire 9 connected to the first winding roller 31 and the second winding roller 32 is opposite to the winding direction .

In the present invention, the steel wire 9 is transported through the first guide roller 1, the first winding roller 31, the second winding roller 32 and the second guide roller 2 in turn for turning and guiding, and the steel wire 9 is at both ends of the device. The equipment can be mounted. During this process, if the wire 9 at both ends needs to be retracted, it is only necessary to start the driver 341 to drive the rotating column 34 to drive the connecting column 33 to rotate, then the first winding roller 31 and the second winding The winding roller 32 will rotate around the axis of the rotating column 34, and since the winding direction of the wire 9 connected to the first winding roller 31 and the second winding roller 32 is opposite, the wire 9 is wound around the first winding roller 32. The outer ring of the roller 31 and the second winding roller 32 is rolled up, as shown in FIG. 2 . On the contrary, if the wire 9 at both ends needs to be released, the driver 341 can be driven to rotate in the opposite direction to complete the release of the wire. The retractable wire 9 can be controlled when the wire 9 is in use in the stage performance, and both ends of the wire 9 can be retracted and retracted at the same time, which effectively solves the problem that the traction machine can only retract one end of the wire 9, or one end rises and the other end falls. The control is inconvenient, effectively creating a variety of control effects guided by the stage wire 9, and the stage effect is better.

In addition, the first guide roller 1 , the second guide roller 2 and the driver 341 are all fixed to the stage frame through a mounting rod 11 , and the mounting rod 11 is a telescopic rod. The first guide roller 1, the second guide roller 2 and the driver 341 are mounted on the top frame of the stage through the mounting rod 11, which facilitates the running stability of the first guide roller 1, the second guide roller 2 and the driver 341, and The installation rod 11 is a telescopic rod. Generally speaking, there is a telescopic cylinder behind the installation rod 11 to control the expansion and contraction of the installation rod 11 to ensure that the entire device extends to the best wire 9 guiding position for the wire 9 to guide.

The utility model has the advantages of simple structure and good guiding stability of the steel wire for the stage. The steel wire can be retracted and released, which is convenient for adjustment, can realize the simultaneous retraction and release control of both ends of the steel wire, and has a good stage effect.

Embodiment 2, as shown in Figures 1 to 3, is only one of the embodiments of the present invention. In order to make the lifting effect of a stage wire guide device of the present invention better and the degree of control higher, the Also available in the following designs:

The end of the rotating column 34 close to the connecting column 33 is provided with a limiting block 35 . The second limit block 352 extends in the direction, the connecting column 33 is provided with a limit chute 331 for facilitating the sliding of the second limit block 352, and at least a part of the second limit block 352 is located in the limit. The number of the first limiting blocks 351 is two, and the two first limiting blocks 351 are respectively connected to the two side surfaces of the connecting column 33 . The two first limit blocks 351 are clamped on both sides of the connecting column 33 to limit the rotation column 34 , and the second limit block 352 of the rotating column 34 can move along the limit chute 331 on the connecting column 33 . .

When the rotating column 34 drives the connecting column 33 to rotate, the first winding roller 31 and the second winding roller 32 will rotate around the axis of the rotating column 34 , and the rotation radius of the first winding roller 31 is the rotating column 34 The sum of the length of the axis from the axis of the first winding roller 31 and the radius of the first winding roller 31. Similarly, the radius of the rotation of the second winding roller 32 is the distance between the axis of the rotating column 34 and the second winding roller. The sum of the length of the axis of 32 and the radius of the second winding roll 32, wherein the radius of the first winding roll 31 and the second winding roll 32 cannot be changed. The rotation radius of the roller 32 can only change the distance from the first winding roller 31 and the second winding roller 32 to the axis of the rotating column 34, and the rotating column 34 slides along the limit chute 331 on the connecting column 33, so that the The distance between the axis of the rotating column 34 and the first winding roller 31 and the second winding roller 32 can be changed, so that the winding speeds of the steel wires 9 at both ends are different.

In a word, when the rotating column 34 is displaced along the limit chute 331 to one end of the connecting column 33, the turning radius of the winding roller at this end is reduced, and the winding and unwinding speed of the wire 9 at this end is slowed down.

It should be noted that, every time the connecting column 33 rotates by 180 degrees, the rotating column 34 has to be displaced once, and is displaced toward the rope end of the wire 9 that needs to reduce the retraction speed.

Of course, the number of the second limiting blocks 352 is at least one, which ensures the stability of the connection between the rotating column 34 and the connecting column 33, and can also share the torque during rotation.

The third embodiment, as shown in Figures 1 to 3, is only one of the embodiments of the present utility model.

When the driver 341 is activated, the telescopic cylinder is activated to drive the first rotating shaft 311 and the second rotating shaft 321 to expand and contract, which will cause the wire 9 to be wound around the outer circles of the first winding roller 31 and the second winding roller 32 When the wire 9 is spirally wound on the surfaces of the first winding roller 31 and the second winding roller 32, it will not cause the wire 9 to be wound later to press the wire 9 wound earlier, and it will not cause the wire 9 to be wound. When winding, it is convenient to reversely rotate the driver 341, and the steel wire 9 is effectively released.

Even because the steel wire 9 is spirally wound on the surfaces of the first winding roll 31 and the second winding roll 32, the outer circles of the first winding roll 31 and the second winding roll 32 are wound after the steel wire 9 is wound. , it can still ensure that the steel wire 9 is transported between the first guide roller 1 , the first winding roller 31 , the second winding roller 32 and the second guide roller 2 , and the control sensitivity is higher.

Moreover, the outer diameters of the first winding roller 31 and the second winding roller 32 are the same, so that the wire 9 is more convenient to retract.

Moreover, the surfaces of the first winding roller 31 and the second winding roller 32 are coated with a friction coating, which increases the friction between the steel wire 9 and the surfaces of the first winding roller 31 and the second winding roller 32 to ensure that the steel wire 9 During the retracting and unwinding process, the surfaces of the first winding roller 31 and the second winding roller 32 will not slide along the axial direction of the first winding roller 31 and the second winding roller 32, and the steel wire is only 9 It will be transported along the surfaces of the first winding roller 31 and the second winding roller 32 with the rotation of the first winding roller 31 and the second winding roller 32 .
