Description

Technical Field

[0001] The utility model relates to the technical field of stage equipment, in particular to a stage with a hanger anti-slip structure. Background Art

[0002] The stage hanger (suspender rod) is an indispensable and important equipment on the stage. It can be used to hang lamps, audio equipment, cloth and other stage equipment, and undertakes important tasks. However, due to the special nature of the stage hanger, if it is not used and maintained correctly, it will cause serious safety accidents. When the stage hanger rod is raised and lowered, a stage electric hoist is generally used. The main electric hoist can provide low-energy operation, suitable for long-term operation, meet the needs of stage operations, and is equipped with a limit switch and an adjustable spiral limit switch to ensure that the motor automatically stops when it is lifted up and down, prevent the chain from exceeding, and ensure safe operation.

[0003] In the prior art, in order to meet the load-bearing requirements, most stage hoists are composed of steel structures. When hoisting through the hook on the electric hoist, it is necessary to equip one end of a sling or a wire rope through the steel structure, and then hang both ends on the hook of the electric hoist. Since both ends need to be hung on the hook, during manual operation, if the diameter of the hook is too small, the eyelets at both ends of the sling or wire rope are not fully combined, which may cause the sling to slip during the hoisting process, causing the hoisted object to fall and lead to a safety accident. Therefore, we propose a stage with a hanger anti-slip structure to solve the above problem. Utility Model Content

[0023] The outer walls of the four cylinders 5 are each provided with a T-shaped groove 6, and the inner walls of the four T-shaped grooves 6 are each slidably connected with a T-shaped column 7. The threaded sleeve 4 is screwed onto the cylinder 5 to limit the T-shaped column 7 in the T-shaped groove 6. The four T-shaped columns 7 are each fixedly connected to the same first steel wire rope 9 in groups of two. The outer walls of the four threaded sleeves 4 are each provided with a through hole 8, and the inner walls of the four through holes 8 are respectively slidably connected to the outer walls at both ends of the two first steel wire ropes 9.

[0024] One end of the four cylinders 5 is fixedly connected to a connecting column 10, and one end of the threaded sleeve 4 is squeezed against the outer wall of the connecting column 10. One end of two connecting columns 10 is fixedly connected to a round sleeve 13, and the inner walls of the two round sleeves 13 are slidably connected to the outer wall of one of the cross bars 1. The round sleeve 13 is used in conjunction with the cross bar 1. The outer walls of the two round sleeves 13 are provided with threaded holes 14, and the existing drilling screws are passed through the threaded holes 14 and screwed into the cross bar 1. One end of the other two connecting columns 10 is fixedly connected to a return hook 15, and the two return hooks 15 are respectively hung on the hooks of the two electric hoists. The return hook 15 is made of stainless steel.

[0025] The outer wall of the connecting column 10 is provided with a traction mechanism, which includes two second steel wire ropes 12.
