Technical Field

The invention relates to the technical field of stage equipment,

in particular, the present invention relates to a stable lift stage.

Background

Along with the increasing abundance of cultural life, people have higher and higher requirements on stage effects in performance activities, and in order to enable performance arts to generate unusual special effects, various types of stage mechanical equipment are installed in modern various large-scale performance places and the like, and the stage mechanical equipment plays the roles of drawing dragon eyes and making a look in the stage performance.

In the modern stage design, in order to create a vivid and active stereoscopic performance effect, the traditional static stage is gradually abandoned, and instead, a liftable stage is adopted. In some large and medium-sized theaters, the condition requirements required by the theaters are considered in the early planning, so that construction according to drawings is only needed in the civil engineering. The regional requirement of satisfying the theater performance that can be fine of stage that sets up, and some small-size theaters receive the restriction of multiple condition, and the regional area of stage of theater configuration is fixed limited, and the stage does not have the condition at all to dispose the elevating platform in addition, and that just can't transform the performance form and increase the stage region, even if install simple and easy lift platform additional, the amplitude of lift is uncontrollable, and the stage quality is big, and elevating platform stability is low, and the stage security is poor.

Therefore, in order to solve the above problems, it is necessary to design a reasonably stable lifting stage frame.

Disclosure of Invention

The invention aims to provide a stable lifting stage frame which is simple in structure, convenient to adjust, good in lifting effect and high in stage safety, and can finish the lifting of a stage by using a winch and a pull rope.

In order to achieve the purpose, the invention is realized by adopting the following technical scheme:

the utility model provides a stabilize lift stage frame, include the pit seat, set up in movable rod in the pit seat and set up in the movable table of movable rod top, the movable rod include the bull stick and set up in the pivot of bull stick tip, the bull stick winds the pivot is rotated, be provided with the stay cord on the pit seat and be used for the pulling the hoist engine of stay cord, the bull stick both ends all are provided with the convenience the rotation wheel that the stay cord passes through, the bull stick pass through the connecting rod with the movable table is connected, the connecting rod wind with the connecting portion of bull stick rotate, the movable table bottom is provided with the convenience the gliding spout of connecting rod.

Preferably, the number of the winches is at least one.

Preferably, the number of the winches is two, and both ends of the pull rope are connected with the winches.

Preferably, the side wall of the movable table is provided with a limiting bulge, and the inner wall of the pit base is provided with a limiting groove for facilitating the sliding of the limiting bulge.

Preferably, the limiting groove extends in the vertical direction.

Preferably, the number of the limiting protrusions is at least one.

Preferably, the number of the limiting grooves is at least one.

Preferably, the number of the rotating rods is at least one, and the number of the connecting rods and the number of the sliding grooves are at least one.

Preferably, at least a part of the end of the rotating rod is arc-shaped.

Preferably, a trapezoidal block is arranged at the end part of the connecting rod close to the sliding groove.

Preferably, the upper surface of the trapezoidal block is horizontally arranged with the sliding groove, and the upper surface of the trapezoidal block is vertically arranged with the connecting rod.

In the present invention, it is preferable that the pit base is provided with a guide wheel for guiding a direction of the rope.

Preferably, at least a part of the bottom end of the side wall of the movable table is arc-shaped.

The stable lifting stage frame has the beneficial effects that: simple structure is convenient for adjust, uses hoist engine and stay cord can accomplish the stage and goes up and down, and it is effectual to go up and down, and the stage security is high.
