Abstract

The invention relates to the technical field of stage lifting devices, and particularly discloses an activity square stage truss. The activity square stage truss comprises a first truss body, a secondtruss body and a third truss body; the third truss body is connected with the first truss body and the second truss body, rockers are hinged to the first truss body and the second truss body correspondingly, a transverse plate is arranged on the lower portion of the third truss body, a first sliding block is hinged to one end of each rocker, a second sliding block is hinged to the other end of each rocker, and the first sliding blocks are horizontally and slidably connected to the side wall of the transverse plate; hydraulic cylinders are mounted on the two sides of the transverse plate correspondingly, a horizontal plate is connected to the output ends of the hydraulic cylinders, and the second sliding blocks are horizontally and slidably connected to the side wall of the horizontal plate; and a cylinder body is arranged on the lower portion of the transverse plate, a piston is slidably connected into the cylinder body, a telescopic rod is fixedly connected to the piston and connected to the transverse plate, the cylinder body communicates with an air inlet pipe and an air outlet pipe, the air outlet pipe is connected with an elastic airbag, and the elastic airbag is mounted on the third truss body. According to the activity square stage truss, the safety during mounting stage apparatus in mid-air by workers can be ensured, and fall damage of personnel is avoided.

Description

technical field [0001] The invention relates to the technical field of stage lifting devices, and specifically discloses a stage truss for an activity square. Background technique [0002] At present, the frames of the stages on many event plazas are made of trusses. After the truss is built into the stage frame, it is necessary to install some stage equipment such as stage lamps and props on the truss above the stage. At this time, the staff needs to climb the truss to the top of the stage or climb to the top of the stage with a ladder on the truss, and then install the stage equipment. During the above process, the safety of the staff cannot be guaranteed, and it is very likely that a fall event will occur, resulting in injury to the staff. Therefore, need a kind of device that can protect staff to install stage equipment above the stage. Contents of the invention [0003] The present invention intends to provide a stage truss for a movable square to solve the problem...
