A rod accommodating groove, a lifting rod is rotatably connected in the lifting rod accommodating groove, two wire reels are fixed on the right side of the support base, and each of the wire reels is fixedly connected with one end of the lifting rope, so The lift rope is wound on the spool; a driven gear is fixed on the lift rod on the left side of the support base, a driving gear is arranged just below the driven gear, and the driving gear and the driven gear are connected through a chain drive, A rotating shaft is fixed vertically through the center of the driving gear. Both ends of the rotating shaft are rotatably connected to the frame. One end of the rotating shaft extends to the outside of the frame and is vertically fixed to the turntable. The edge of the turntable is threadedly connected with a limit screw. A threaded pipe which is threadedly matched with the limit screw is fixed on the upper part.

Preferably, two bearings are sleeved on the lifting rod, and the bearings are installed in the accommodating groove of the lifting rod.

Preferably, limit plates are fixed on both the left and right sides of the support base on the lift rod.

Preferably, mounting blocks are fixed on both sides of the bottom of the frame, and the mounting blocks are connected to the ground through connecting bolts.

Preferably, the lift rope is a steel wire rope.

Preferably, the lengths of the lift ropes on the two spools are equal.

The beneficial effects of the present utility model are:

1. In the present invention, by rotating the driving gear, the driving gear drives the driven gear to rotate through the chain, so that the driven gear drives the lifting rod to rotate, so that the spool can stow or lower the lifting rope, so that the stage connected with the lifting rope is made to rotate. The boom is raised or lowered. Although the lifting and lowering of the stage boom requires manual operation, the overall cost is reduced because the motor is not used, and it can be widely used in the occasions where the stage boom does not need frequent lifting.

2. After adjusting the position of the stage boom, the position of the stage boom can be fixed by installing the limit screw on the threaded pipe.

Detailed ways

In order to make it easier to understand the technical means, creative features, goals and effects realized by the present invention, the present invention will be further described below in conjunction with the specific embodiments and the accompanying drawings, but the following embodiments are only the preferred embodiments of the present invention. , not all. Based on the examples in the implementation manner, other examples obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

As shown in Figure 1-2, an L-shaped stage boom lift includes a support base 3, a mounting plate 2 is fixed on the top surface of the support base 3, and the edge of the mounting plate 2 is connected to the roof through a plurality of mounting bolts 4, supporting A lifting rod accommodating groove 10 is horizontally opened in the seat 3, and a lifting rod 9 is rotatably connected in the lifting rod accommodating groove 10. Limiting plates 8 are fixed on the lifting rod 9 on the left and right sides of the support seat 3, and the lifting rod 9 is located on the left and right sides. Two spools 6 are fixed on the right side of the support base 3. Each spool 6 is fixed to one end of a lifting rope 12. The lifting rope 12 is a steel wire rope. The lifting ropes 12 on the two spools 6 are of equal length. It is wound on the spool 6; the lifting rod 9 is fixed with a driven gear 1 on the left side of the support base 3, and a driving gear 13 is arranged directly below the driven gear 1, and the driving gear 13 and the driven gear 1 are connected by a chain 7. A rotating shaft 14 is fixed vertically through the center of the driving gear 13. Both ends of the rotating shaft 14 are rotatably connected to the frame 15. One end of the rotating shaft 14 extends to the outside of the frame 15 and is vertically fixed to the turntable 20.
