Description

Technical Field

[0001] The utility model belongs to the technical field of performance equipment, and in particular relates to a spiral lifting device for evacuating actors. Background Art

[0002] When a mechanical failure occurs on the actor's own performance lifting platform during a performance, the actors need to be evacuated in time. The existing spiral lifting device uses a pneumatic cylinder as a drive for lifting. Due to the special shape of the evacuation platform, which is a spiral shape, it is necessary to arrange multiple pneumatic cylinders under the evacuation platform. However, due to the compressibility of air, the movement speed of the cylinder is easily affected by changes in load. In addition, the transmission speed of pneumatic signals is much lower than that of electrical signals, and there is a large delay and distortion. It is not suitable for complex systems that require high-speed signal transmission and cannot meet the requirements of rapid evacuation. Utility Model Content

[0003] The utility model aims to provide an actor evacuation spiral lifting device, which divides a lifting platform into two parts. During use, the two platforms are lifted synchronously and meet the rapid evacuation needs of the actors after reaching the designed height together.

[0004] The utility model provides a spiral lifting device for actor evacuation, comprising a first lifting platform and a second lifting platform, wherein the first lifting platform and the second lifting platform are overlapped and used to reach a height that meets the actor evacuation requirements through synchronous lifting;

[0005] The first lifting platform and the second lifting platform both include a top platform, a spiral lifting screw, a reduction motor, a universal coupling, and an electric latch; the top platform is connected to the spiral lifting screw, the spiral lifting screw is connected to the universal coupling, and the universal coupling is connected to the reduction motor, so as to transmit the output power of the reduction motor to the spiral lifting screw, thereby driving the top platform to perform lifting action;

[0006] The spiral lifting screw is provided with a self-locking device; the reduction motor is equipped with a brake and a manual release brake device; the electric latch is used to extend to the lower end of the spiral lifting screw when the first lifting platform and the second lifting platform are raised to the required height to prevent the top platform from descending.

[0007] Furthermore, the first lifting platform and the second lifting platform also include a supporting mechanism, and the supporting mechanism is used to support the spiral lifting screw, the reduction motor, the universal coupling, and the electric latch.

[0008] Furthermore, the bottom end of the support mechanism is fixedly connected to an embedded plate arranged on the concrete floor.

[0009] Furthermore, the first lifting platform and the second lifting platform also include an electric lifting guardrail connected to the top platform.

[0010] By means of the above scheme, the following technical effects are achieved through the actor evacuation spiral lifting device:

[0011] 1) The lifting platform is divided into two parts. During use, the two lifting platforms are lifted synchronously to reach the designed height. The lifting platform adopts a spiral lifting screw, a reduction motor, and a universal coupling transmission method to meet the rapid evacuation needs of the actors.

[0012] 2) Safety is ensured by triple protection of motor brake, self-locking screw and safety latch.

[0013] 3) By manually releasing the brake device, in case of failure or power failure of the spiral lifting device, the spiral lifting device can be freely raised and lowered by manually turning the gear.

After the latch is retracted, it does not affect the normal lifting of the lifting platform.

[0026] In this embodiment, the first lifting platform 1 and the second lifting platform 2 further include a supporting mechanism 11 , and the supporting mechanism 11 is used to support the spiral lifting screw 3 , the reduction motor 4 , the universal coupling 7 , and the electric latch 5 .

[0028] In this embodiment, the first lifting platform 1 and the second lifting platform 2 further include an electric lifting guardrail 8 connected to the top platform 10. In order to prevent the railing from occupying the performance space, when there is no evacuation, the railing is at the lowest position. Once there is an evacuation demand, the electric lifting guardrail automatically rises to a height of about 1.1m to ensure the absolute safety of personnel during the high-altitude evacuation process.
