Description

A mobile stage light

Technical field

The invention belongs to the field of lighting equipment, and particularly relates to a mobile stage light.

Background technique

Stage lighting plays a vital role in modern stage performances. Through the stage lighting performance, the audience can see the actor's performance and the image of the scene clearly; guide the audience's sight; shape the character image to contrast emotion and show the stage illusion; render the atmosphere; show the transformation of time and space, change the rhythm of the stage, and enrich the artistic appeal. Sometimes it also cooperates with stage stunts.

In order to change with the stage effect, the position of the stage light needs to be adjusted; therefore, the stage light is installed on a rail car set on and around the top of the stage, and the position and height of the stage light are adjusted by controlling the rail car to move on the track.

Since railcars and stage lights installed on railcars need power supply to ensure normal operation, railcars and stage lights and other electrical equipment require different working voltages under normal circumstances and cannot be powered by a single line. In addition to power supply requirements, some electrical equipment also requires communication connections. As a result, multiple lines need to be dragged during the operation of the railcar, which is prone to line entanglement. When multiple rail cars are installed on the same track, the messy lines will cause multiple rail cars to be entangled by the line and affect their operation.

During the operation of the railcar, the car body will vibrate. At the same time, the stage lights installed on the car body will be rotated or telescopically adjusted by telescopic rods. The vibration of the car body and/or the stage lights will be too large. There is a danger that the stage lights will be damaged or even fall off from the car body.

In summary, there is an urgent need for a moving stage lamp that can hide the circuit while avoiding the impact caused by vibration or shaking.

The three-phase switch can be electrically connected to any conductive slot through the carbon brush in the first carbon brush assembly and block its electrical connection with the other two conductive slots; thus, the three-phase switch can be used to select one of the three-phase power sources The purpose of phase line connection. When the load of two phase lines of the three phase lines of the three-phase power supply is saturated, the railcar can be connected to the other phase line through the three-phase switch to achieve the purpose of distributing the load and avoid the excessive load of the single phase line.

The traveling mechanism generates vibration during the movement, which causes the rotation shaft to be displaced with the vibration of the traveling mechanism. When the distance between the rotation shaft and the servo motor changes, the adjustment component releases an appropriate amount of redundancy of the flexible transmission part to make the flexible transmission part Extend to ensure the transmission connection between the servo motor and the shaft. In the adjustment assembly, the idler is axially connected to the mounting seat, and the sliding direction of the mounting seat intersects with the flexible transmission member.

Example 2:

On the basis of Embodiment 1, in order to optimize the performance of the energized guide rail 11 and the communication guide rail 12, the following improvements are made to the technical solution:

In an embodiment, as shown in FIGS. 4 and 15, in order to establish at least two information channels that do not interfere with each other, the communication guide 12 includes a plurality of track grooves 121 fixedly arranged on the body of the track 1; The track groove 121 is provided with an insulating pad 122; the surface of the insulating pad 122 is provided with a conductive strip 123; the first brush set 2321 includes a plurality of first communication carbon brushes, any first communication carbon brush and any conductive strip 123 Electrical contact; the second brush set 2322 includes a number of second communication carbon brushes, any second communication carbon brush is in electrical contact with any conductive strip 123; any one of the conductive strips 123 is only in electrical contact with the first communication carbon brush Or only make electrical contact with the second communication carbon brush.

In one embodiment, as shown in FIG. 4, in order to improve the circuit stability of the rail car 2, the energized guide rail 11 includes four conductive grooves 111 connected to the body of the track 1, wherein three conductive grooves 111 are respectively connected to Into the three phases of the three-phase power supply, the other conductive slot 111 is grounded. The energized guide rail 11 is connected to the three phase lines of the three-phase power supply to provide stable three-phase power supply for the rail car 2. At the same time, a ground wire is connected to the fourth conductive groove 111 to avoid electric shock accidents caused by the conduction of the rail 1 and the shell of the rail car 2.

In one embodiment, in order to switch between the three phase lines of the three-phase power supply of the rail car 2 to distribute the load, the rail car 2 further includes a three-phase switch 6; the first carbon brush assembly 231 includes several Energized carbon brushes, any one of the conductive grooves 111 is in electrical contact with at least one of the energized carbon brushes; a plurality of energized carbon brushes are all electrically connected to the three-phase switch 6, and the three-phase switch is electrically connected to the traveling mechanism 22 .

Example 3:

On the basis of Embodiment 1 or Embodiment 2, in order to weaken the vibration amplitude generated by the rail car 2 and thereby reduce the impact on the stage lights 4, the technical solution is improved as follows:

In one embodiment, in order to reduce the vibration generated during the operation of the rail car 2 itself, the walking mechanism 22 includes a servo motor 221 installed in the car body 21, a rotating shaft 222 connected to the servo motor 221 in a driving manner, and A wheel arranged on the rotating shaft 222; the rotating shaft 222 is connected to the vehicle body 21 through a shock-absorbing mechanism 24; the shock-absorbing mechanism 24 includes a mounting plate 241 and a shock-absorbing plate 242, and the mounting plate 241 is axially connected to With respect to the rotating shaft 222, the mounting plate 241 is connected to the shock absorbing plate 242 through a buffer 243; the shock absorbing plate 242 is fixed to the vehicle body 21. During the movement of the rail car 2, the vibration generated by the traveling mechanism 22 during the movement is first transmitted from the shaft 222 to the mounting plate 241, then to the buffer 243, and finally to the car body 21; in this vibration transmission process, Due to the cushioning effect of the cushioning member 243, the vibration effect is greatly weakened or even eliminated after passing through the cushioning member 243. To ensure the stability of the entire transfer device.

In an embodiment, the damping plate 242 includes a plate body 2422, a first mounting block 2423 fixedly connected to the plate body 2422; the first mounting block 2423 is used to connect with the vehicle body 21; A gap for accommodating the mounting plate 241 is formed between the plate body 2422 of the shock-absorbing plate 242 after the mounting block 2423 is connected to the car body 21 and the car body 21; the width of the gap is greater than the thickness of the mounting plate 241 . In order to avoid the instability of the connection between the mounting plate 241 and the vehicle body 21 through the buffer member 243, the problem of separation of the mounting plate 241 and the vehicle body 21 is likely to occur. When the damping plate 242 is installed on the outer wall of the vehicle body, a gap is reserved, and the mounting plate 241 is set through the gap. During the vibration process, the mounting plate 241 moves with the vibration in the gap, and cooperates with the buffer 243 to achieve a shock absorption effect, and it is inconvenient to maintain the distance between the mounting plate 241 and the vehicle body 21 due to the restraint of the shock absorbing plate 242.
