Operation parachute jump for confined space and method of use

Abstract

The invention relates to an operating umbrella fastener used in a limited space and a use method thereof. The operating umbrella fastener comprises a control rod, a lifting lug, a bearing rod, an ejector rod, a movable platform, an operating platform, a bottom plate base, a traction sliding sleeve and a pull rod, wherein the lifting lug is fixed on the upper end of the bearing rod while the lower end of the bearing rod is connected to a base; the control rod is inserted inside the bearing rod; the bottom end of the control rod is fixedly connected to the traction sliding sleeve through a sliding sheet; a sliding seam is formed in the outer wall of the bearing rod; the sliding sheet slides in the sliding seam; an ejector rod base with a screw thread is fixedly connected to both the operating platform and the movable platform; the bearing rod and a worm wheel and worm lifting mechanism are connected through a screw thread pair; a gear rotation mechanism is arranged at a lower part of a base plate; the movable platform is connected to the bottom plate base through a first hinge; one end of the pull rod is movably connected to the traction sliding sleeve while the other end of the pull rod is movably connected to the operating platform. The advantages are that since the foldable structure is adopted, the operating umbrella fastener which can be folded and unfolded can be put into use in the limited pace from a relatively small hole when the operating umbrella fastener is in a folded state and is used in a narrow and small space.

Description

technical field [0001] The invention relates to an operation parachute used in a confined space and a use method thereof. Background technique [0002] In the process of production and maintenance, it is often encountered that the opening is narrow and the interior needs to be repaired, such as the chimney and the waste heat boiler. Dismantling temporary ladders and work platforms (supporting maintenance personnel and argon arc welding equipment) will not only take a long time but also be dangerous. At the same time, during the maintenance process, it is necessary to weld supports on the boiler tube wall, and then use gas welding to cut them off at the end of the maintenance. Damage to the boiler body greatly increases the labor intensity of maintenance personnel. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a working platform for parachute jumping and its use in a confined sp...
