4results about How to "Solve lifting difficulties" patented technology

The utility model belongs to the technical field of electric power line hot-line work, and discloses a disconnected branch line lifting and doubling device for hot-line work, which comprises a base, a first fixing seat, an insulating rod, a second fixing seat, a clamping seat and a main line support. The first fixed seat is fixed on the base, and the second fixed seat is arranged above the first fixed seat; the lower end of the insulating rod is fixedly connected with the first fixing seat, and the upper end is fixedly connected with the second fixing seat. The clamping seat is slidably connected to the insulating rod and used for clamping the parallel groove clamp, and the clamping seat can drive the parallel groove clamp to move towards the direction of the second fixing seat; the main line support is movably connected to the second fixing base and used for hooking a main line. And the main line bracket can move along the direction of the second fixing seat, so that the main line bracket and the clamping seat are close to each other, and the main line is embedded into a line slot of the parallel groove clamp. The device provided by the utility model is easy to operate, can solve the problem that the upper arm is easily tired when being manually lifted and the problem that a large-wire-diameter branch wire is difficult to lift, and is good in applicability and strong in practicability.

The application provides a lifting device and an air conditioning unit, the lifting device is used for driving a fan assembly of the air conditioning unit to perform lifting movement, and the lifting device comprises a fixed plate used for bearing the fan assembly; a lifting assembly rotatably connected with the fixed plate, a bottom end of the lifting assembly used for contacting a supporting base surface; and a transmission assembly connected with the lifting assembly to drive the lifting assembly to rotate relative to the fixed plate, so that the bottom end of the lifting assembly moves relative to the supporting base surface, and the fixed plate is lifted relative to the supporting base surface to drive the fan assembly to perform lifting movement. The fan assembly is lifted by the lifting device and supported after descending, so that the problems of difficult lifting and difficult bottom supporting of the fan assembly in the air conditioning unit in the prior art are solved.

The application provides a lifting device and an air conditioning unit, the lifting device is used for lifting operation of a fan assembly, and the lifting device comprises a lifting frame, a lifting assembly and a supporting assembly, the lifting frame has a moving opening for the fan assembly to pass through; the lifting assembly is connected with the fan assembly to lift the fan assembly on the lifting frame, the lifting assembly is movably arranged relative to the fan assembly to be movably arranged in a vertical direction relative to a supporting base surface through relative movement between the fan assembly and the lifting assembly; the supporting assembly is used for being installed at a bottom end of the fan assembly to support the fan assembly through contact with the supporting base surface when the fan assembly passes through the moving opening and drops to a predetermined position, so that the problem of difficult lifting and difficult bottom support of the fan assembly in the air conditioning unit in the prior art is solved.

The application provides a construction method of a super-large-plate glass curtain wall in a narrow space, and relates to the technical field of glass curtain wall construction, which comprises the following steps: S1, installing steel columns and beams; S2, laying a track on a cantilever platform; S3, manufacturing a mobile trolley and placing the trolley on the track; S4, fixing a winch on the cantilever platform, welding a lifting ring on a roof pre-embedded plate, and passing a steel wire rope of the winch through the lifting ring; S5, hoisting a glass panel onto the mobile trolley; S6, driving the mobile trolley to a mounting position, lifting the glass panel by using a glass suction cup and the winch, lifting the glass panel to the mounting position, and fixing the glass panel on a curtain wall keel frame. The track and the mobile trolley are used to realize the mobile transportation of the glass panel in the narrow space, the lifting ring is welded on the roof pre-embedded plate, the winch and the lifting ring are used to realize the hoisting and lifting of the glass panel in the narrow space, and the problem that a hoisting vehicle cannot hoist and move the glass panel in the narrow space is solved.
