The logs are fixed with half-clad iron by bolts, and one end of the half-clad iron is fixed with a positioning pipe by bolts, and a trolley is connected on the positioning pipe.

A channel steel diagonal brace is fixedly installed between the cylindrical iron cladding and the channel steel, a hook is connected to one end of the insulating rope, a gourd hanging lug is fixed at the bottom of the channel steel, and a gourd assembly is installed at the bottom of the gourd hanging lug.

The total length of the log is 7 meters, the diameter of the bottom of the log is 30 cm, and the diameter of the top of the log is 12 cm.

The thickness of the cylindrical iron cladding is 4 mm, the length of the cylindrical iron cladding is 40 cm, the connection between the cylindrical iron cladding and the log is welded, and the diameter of the channel steel is 12 cm.

The diameter of the positioning tube is 3 centimeters, and the length of the positioning tube is 15 centimeters.

A handle is arranged horizontally on the top of the latch rod.

The beneficial effects of the utility model are: in view of the existing technical problem that outdoor electrical equipment weighing hundreds of kilograms cannot be safely dismantled and hoisted and installed by manpower, the dual-purpose lifting device of vertical electric and manual control is adopted, so It is very convenient to carry out hoisting installation and manpower safe dismantling.

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

The utility model provides a small-sized spacer dual-purpose lifting device, which includes a lifting device and a trolley capable of moving heavy objects. The lifting device includes a bottom fixing seat, which is fixed on the ground through a pair of bolt rods, and the bottom Logs are vertically fixed on the seat, a winch frame is fixed on one side of the bottom fixed seat, a hoist is installed on the hoist frame, a cylindrical iron-clad is set on the top of the bottom fixed seat, and a channel steel is fixed horizontally on the top of the cylindrical iron-clad The two ends of the channel steel are provided with pulleys through the mandrel, and the same side of the log and the cylindrical iron clad are provided with a guide wheel assembly. The hook can automatically lift heavy objects, saving manpower and improving labor time.

The log is fixed with half-clad iron by bolts, and one end of the half-clad iron is fixed with a positioning tube by bolts. The positioning tube is connected with a trolley, which can load and support heavy objects at the same time when lifting heavy objects.

A channel steel diagonal brace is fixedly installed between the cylindrical iron cladding and the channel steel, and the bottom end of the channel steel is fixed with a gourd hanging lug, and a gourd assembly is installed at the bottom of the gourd hanging lug, which can lift heavy objects manually.

The total length of the log is 7 meters, the diameter of the bottom of the log is 30 cm, and the diameter of the top of the log is 12 cm, which is the best use effect.

The thickness of the cylindrical iron cladding is 4 mm, the length of the cylindrical iron cladding is 40 cm, the connection between the cylindrical iron cladding and the log is welded, and the diameter of the channel steel is 12 cm to ensure that the lifting device is more stable.

The diameter of the positioning tube is 3 centimeters, and the length of the positioning tube is 15 centimeters, which has the best effect.

A handle is arranged horizontally on the top of the latch rod, which facilitates the insertion and extraction of the latch rod, and thus facilitates the removal of the lifting device by manpower.

When in use, first two people hold the lifting device and lift it to the designated position. The two people use insulating ropes to tie the top of the log to a place 2 meters down and pull it up. The other person hugs the bottom of the log with both hands and keeps the lifting device upright. Use the prepared pull rope to tie it to some available brackets, and insert the bottom of the log with the bottom fixing seat bolt rod. Before fixing, pay attention to the lifting direction. After placing the lifting object on the lifting center point, use the hook to hang it Heavy objects can only be lifted.

In the case of a power outage on site, use a chain hoist, use an insulating rope to pass through the ring hole, pull the hoist to the position, and hang the heavy object to lift it.

The utility model aims at the problem that the outdoor electrical equipment weighing hundreds of kilograms cannot be safely dismantled and hoisted and installed by manpower in the existing technology, and adopts the dual-purpose hoisting device mode of vertical electric and manual control, so it can be easily hoisted Installation and manual safe removal.
