[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides two technical solutions: specifically including the following embodiments:

[0023] Example 1

[0024] See also Figure 1-Figure 3 A stage curtain hoist includes a driving motor 1, which is controlled by an external switch and electrically connected to an external power supply. A winding drum 2 is fixed to the output end of the driving motor 1, and a steel wire rope is wound on the winding drum 2. A bottom plate 3 is fixed to the bottom of the driving motor 1, and a mounting plate 4 welded to the equipment conversion layer is arranged below the bottom plate 3. The stage curtain hoist needs to be welded to a structural support body above the stage. This structural support body is usually called an "equipment conversion layer". The equipment conversion layer is a structural layer specially used to provide installation and support for stage equipment. It is located on the top of the stage and hidden from the audience's sight. A mounting mechanism 5 is arranged between the mounting plate 4 and the bottom plate 3;

[0025] The mounting mechanism 5 includes a groove 51 formed on the top of the mounting plate 4. The bottom of the base plate 3 extends to the inside of the groove 51. The size of the base plate 3 is matched with that of the groove 51. Square grooves 52 are formed on both sides of the mounting plate 4. Slide rods 53 are slidably connected to both sides of the mounting plate 4. Two transverse grooves 54 are formed inside the mounting plate 4. The two transverse grooves 54 are connected to the groove 51. The opposite ends of the two slide rods 53 pass through one side of the mounting plate 4 and extend to the inside of the transverse groove 54. Trapezoidal blocks 55 are fixed to the opposite ends of the two slide rods 53. One side of the two trapezoidal blocks 55 extends to the inside of the square groove 52. Springs 56 are sleeved on the outer surfaces of the two slide rods 53. The bottom of the base plate 3 contacts and squeezes the inclined surfaces of the two trapezoidal blocks 55.

[0026] The opposite ends of the two springs 56 are fixed to one side of the trapezoidal block 55 , the ends of the two springs 56 that are away from each other are fixed to the inner wall of the transverse groove 54 , and the ends of the two slide bars 53 that are away from each other are fixed with pull rings 57 .

[0027] By setting the mounting mechanism 5, the base plate 3 and the drive motor 1 can be quickly installed, and the drive motor 1 can be quickly installed on the equipment conversion layer for use without the need to use bolts for disassembly and assembly, which greatly improves the installation efficiency, is simple to operate, and is very practical.

[0028] Example 2

The automatic rope stabilizing assembly 7 includes a bidirectional screw rod 71 rotatably connected between the inner walls of the slide groove 6 .

[0030] A stepper motor 72 is fixed to one side of the mounting plate 4 . The stepper motor 72 can rotate forward and reverse, is controlled by an external switch, and is electrically connected to an external power source. The stepper motor 72 drives the bidirectional lead screw 71 to rotate.

[0031] Two sliders 73 are slidably connected to the inner surface of the slide groove 6 , and one end of the bidirectional screw rod 71 passes through the two sliders 73 and extends to the outside of the slider 73 .

[0032] The outer surface of the bidirectional screw rod 71 is threadedly connected to the inner surfaces of the two sliders 73 , and a limiting plate 74 is fixed to one side of the two sliders 73 .

[0033] By setting the automatic rope stabilizing assembly 7 and utilizing the opposite movement and clamping of two limiting plates 74, the steel wire rope is limited, thereby solving the problem of the steel wire swinging and enabling rapid stabilization when raising and lowering the stage curtain.

[0034] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] During operation, the bottom plate 3 is placed into the groove 51, so that the bottom plate 3 squeezes the two trapezoidal blocks 55 downward, so that the two trapezoidal blocks 55 move back to back, and the trapezoidal blocks 55 drive the two slide bars 53 to move back to back, and at the same time, the trapezoidal blocks 55 begin to squeeze the compression spring 56. When the two square grooves 52 on the bottom plate 3 are docked with the trapezoidal blocks 55, the spring 56 is reset, driving the two trapezoidal blocks 55 to move towards each other, and finally the trapezoidal blocks 55 are inserted into the square grooves 52, so as to realize the installation and fixation of the drive motor 1, start the drive motor 1, so that the drive motor 1 drives the winding drum 2 to rotate, and further the winding drum 2 drives the wire rope to be wound or put down, start the stepper motor 72, so that the stepper motor 72 drives the bidirectional screw rod 71 to rotate, and at the same time the bidirectional screw rod 71 drives the two sliders 73 to move towards each other, and further the sliders 73 drive the two limit plates 74 to move towards each other and limit the swinging wire rope to prevent it from swinging.

[0036] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
