A metal pipe fitting lifting device for engineering construction

Abstract

The invention discloses a lifting device for metal pipe fittings used in engineering construction, which relates to the field of engineering construction and includes a transportation platform, the center of the top of the transportation platform is rotatably connected to a rotating column, the top of the rotating column is fixedly connected to a top frame, and both sides of one end of the top frame are An arm is fixedly connected, and a winch is fixed on the top of the other end of the top frame. The hoist is connected to a wire rope, and the wire rope passes through the top frame and the support arm and is fixedly connected to the fixing device. The jaws and the second jaws, the first jaw is fixedly connected to the first drawstring, the free end of the first drawstring is fixedly connected to the hook, the second jaw is fixedly connected to the second drawstring, and the free end of the second drawstring is fixedly connected Hanging ring, the end seat is provided with an adjustment mechanism, the invention can adjust the opening angle of the jaws by setting the adjustment mechanism, so that it is suitable for steel pipes of different sizes, and the metal pipe can be protected twice by setting the hook and the hanging ring , to prevent the metal pipe from falling during the hoisting process.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a lifting device for metal pipe fittings used in engineering construction. Background technique [0002] For large-scale steel pipes, the lifting operation usually requires the steel pipes to be tied up with ropes before being hoisted by driving, and manual hand support is required during the hoisting process to ensure that the ropes do not slip on the steel pipe surface and cause the steel pipes to fall, which is more dangerous. [0003] In the Chinese utility model patent document with the publication number CN203865840U, a steel pipe hoisting device is disclosed. The device quickly clamps the round pipe through a detachable and quickly installed end sleeve and a positioning cylinder, which can be transported more conveniently and It will not cause the steel pipe to slide down, but when the round pipe is long, it is inconvenient to install and clamp, and it cannot be use...

Problems solved by technology

[0002] For large-scale steel pipes, the lifting operation usually requires the steel pipes to be tied up with ropes before being hoisted by a truck, and manual hand support is required during the hoisting process to ensure that the ropes do not slip on the surface of the steel pipes and cause the steel pipes to fall, which is more dangerous

[0003] In the Chinese utility model patent document with the publication number CN203865840U, a steel pipe hoisting device is disclosed. The device quickly clamps the round pipe through a detachable and quickly installed end sleeve and a positioning cylinder, which can be transported more conveniently and It will not cause the steel pipe to slide down, but when the round pipe is long, it is inconvenient to install and clamp, and it cannot be used for pipe fittings of different diameters
