Technical Field

The utility model relates to the technical field of elevators, specifically a multi-thread dish elevator.

Background

The elevator generally adopts a winding reel to receive and release a lifting wire, and then drags a suspended object to lift through the lifting wire, for example, in stage equipment, in order to obtain a specific lighting effect or a sound effect, the elevator is generally adopted to suspend a lamp or a sound to realize that the lamp or the sound has a lifting function, so as to generate the specific stage lighting or sound effect. At present, the elevators on the market generally have the following problems that generally only one winding roll is arranged, the length of a winding lifting wire is limited, so that the lifting height range of the elevator is limited, if the width of the winding roll is only increased, the length of the winding lifting wire wound on the winding roll is difficult to be substantially increased, because the relative positions of the winding roll and a shell outlet hole (or a guide pulley) are fixed, the lifting wire is subjected to downward tension due to an object suspended by the lifting wire during working, when the winding roll rotates to wind the winding, the lifting wire is basically wound just above the shell outlet hole (or the guide pulley), the winding cannot be uniformly wound in the width range of the winding roll, and due to lack of support of a side plate of the winding roll, the winding is easy to collapse when reaching a certain thickness, so that the operation of the elevator is influenced; although increasing the diameter of the winding roll can also increase the length of the lifting wire wound on the winding roll, the length and height of the elevator can be increased, which results in the overall size of the elevator being too large to be suitable for some narrow use environments.
