Lifting table with function of automatically opening and closing exit

Abstract

The invention relates to a lifting table with a function of automatically opening and closing an exit. The lifting table comprises a mounting frame, four screw rods distributed in a square shape are mounted at the lower end of the mounting frame, and the four screw rods are jointly connected with a driving mechanism. Swivel nuts are mounted on the four screw rods correspondingly, a center stage isjointly mounted on the four swivel nuts, a first rack is fixed to the outer portion of each swivel nut, the first racks are engaged with driving gears correspondingly, and connection shafts are connected with the driving gears correspondingly. Two baffles are slidably and horizontally matched with the mounting frame, movable plates slidably matched with the connection shafts are hinged to the baffles, second racks are fixed to the movable plates, and the second racks are engaged with small gears. A rectangular through hole for allowing the center stage to go in and out is formed in the top ofthe mounting frame. The lifting table has the advantages that the structure is simple, the number of the assemblies is small, and the production cost is low, the purchasing cost of equipment is reduced, opening of the exit of the stage and lifting work of personnel are achieved simultaneously, movement consistency is maintained, occurrence of potential safety hazards is reduced, and using of thestage is facilitated.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a lifting platform for automatically opening and closing an exit. Background technique [0002] As a kind of lifting equipment, lifting platform is widely used in various fields. With the innovation and development of entertainment performance methods, lifting platform is also used more and more frequently in entertainment performances. The traditional way of use is that the protagonist is located on the table of the lifting platform, firstly, the outlet on the stage is opened under the drive of the external hydraulic cylinder, and the lifting platform after activation directly lifts the leading actor onto the stage. [0003] However, this kind of lifting platform has simple functions and low utilization rate of equipment. The exit at the upper end of the stage and the lifting and lowering of the leading role are completed by two parts of power, which is prone to work m...

Problems solved by technology

[0003] However, this kind of lifting platform has simple functions and low utilization rate of equipment. The exit at the upper end of the stage and the lifting and lowering of the leading role are completed by two parts of power, which is prone to work mistakes, resulting in inconsistent movements, causing safety hazards, and seriously endangering the lives and health of personnel. Equipped with other equipment, the structure is complicated and the operation is cumbersome, which is not conducive to use
