Reusable mounted main hoisting device

Abstract

The invention discloses a reusable mounted main hoisting device. The mounted main hoisting device comprises: a lifting lug main plate; a lifting lug pipe shaft, the lifting lug pipe shaft being arranged in front of the lifting lug main plate; a lifting lug baffle, being arranged in front of the lifting lug pipe shaft; a connecting plate, being arranged under the lifting lug main plate, and the connecting plate is provided with a connecting hole. The device has advantages that the reusable mounted main hoisting device prevents direct welding on a device body, and a main lifting lug and an outerreinforcing ring inherent to the device are organically combined by a connecting member. After device hoisting is completed, extension length of the main lifting lug influences subsequent installation of the device, and the connecting member is directly removed, and rapid and non-fire removal of the main lifting lug of the device is realized. A semi-box structure is adopted as a main structural form of the main lifting device, to ensure stability of the main lifting lug structure. The material and dimensions of the main lifting lug are made according to site conditions to make the main hoisting device versatile.

Description

technical field [0001] The invention relates to the technical field of hoisting, and more specifically, to a reusable installation type main hoisting device. Background technique [0002] Hoisting is one of the important types of work in the mechanized construction of construction enterprises. Its content is to lift the components through the equipment and place and fix them in the designed position. [0003] At present, the main lifting lugs of traditional equipment hoisting generally adopt the connection method of welding on the equipment body. The quality requirements for the main lifting lug materials and welding materials are relatively high, and the welding materials of the main lifting lugs must be the same as the material of the equipment body or Similarly, the quality requirements for welding materials are high. In addition, in some narrow equipment installation spaces, the extension length of the main lifting lug of the equipment affects the subsequent installation...

Problems solved by technology

[0003] At present, the main lifting lugs of traditional equipment hoisting generally adopt the connection method of welding on the equipment body. The quality requirements for the main lifting lug materials and welding materials are relatively high, and the welding materials of the main lifting lugs must be the same as the material of the equipment body or Similarly, the quality requirements for welding materials are high. In addition, in some narrow equipment installation spaces, the extension length of the main lifting lug of the equipment affects the subsequent installation of the device to be installed. It is often necessary to remove the main lifting lug after the equipment is hoisted. Cutting, removal, grinding, anti-corrosion, and then subsequent installation, not only time-consuming and labor-intensive but also affect the appearance
