4results about How to "Reduce installation hazards" patented technology

The application provides an assembled precast component hoisting auxiliary device and a use method, which comprises a hoisting beam, hoisting vertical rods, an adjusting seat and a mounting seat, the hoisting beam is provided with a transverse adjusting block, the transverse adjusting block is movable along the length direction of the hoisting beam, the hoisting vertical rods are arranged at the two ends of the hoisting beam and are rotationally connected with the hoisting beam, the adjusting seat is arranged at the end of the hoisting vertical rod away from the hoisting beam, and the mounting seat is arranged on the adjusting seat and is movable in the direction perpendicular to the hoisting beam. The precast component can be adjusted in the hoisting process, the hoisting posture can be close to the mounting posture, no additional posture adjustment is needed during high-altitude installation, the assembly difficulty is reduced, the assembly efficiency is improved, the structure is simple, the operation is convenient, and the installation risk is reduced.

The utility model relates to the technical field of doors and windows, in particular to a sliding anti-jumping mechanism for doors and windows, which comprises a guide rail extending leftwards and rightwards, an anti-jumping seat mounted on the doors and windows and a roller rotationally connected with the anti-jumping seat, and the roller is used for abutting against the guide rail so that the anti-jumping seat can move leftwards and rightwards relative to the guide rail; the guide rail is provided with an anti-jumping groove with a backward opening, and the anti-jumping seat is provided with an anti-jumping protruding block extending into the anti-jumping groove. According to the sliding anti-jumping mechanism for the door and window, when the door and window jumps due to rigid collision, the jumping amplitude of the door and window is limited through the anti-jumping groove and the anti-jumping protruding block, the situation that the jumped door and window body falls off the guide rail and collides with a user is reduced, and the installation hidden danger generated when the door and window moves horizontally is reduced.

The utility model discloses a shield construction muck box hoisting device which comprises a gantry crane trolley, a movable pulley, a connecting beam and a gantry crane main hook cross beam, the two ends of the connecting beam are connected with the movable pulley and the gantry crane main hook cross beam respectively, a plate hook is rotationally connected to the connecting beam, a hoisting hole is formed in the plate hook, and the hoisting hole is connected with the movable pulley. The plate hook is provided with a lifting hole matched with a lifting lug installed on a muck box, and the side portion of the plate hook is connected with a rotation driving assembly to drive the plate hook to rotate along the connecting beam so that the lifting hole can enter or rotate out of the lifting lug. The whole process of the hoisting device does not need manual work, people do not need to arrive at the site in a construction area, and installation hidden dangers are reduced.
