Description

A spreader for hoisting large steel pipes

technical field

The invention relates to the technical field of lifting heavy objects, in particular to a hanger structure for hoisting large steel pipes.

Background technique

In the past, when lifting special materials such as cylinders, it was often done by manual binding, which wasted a lot of time on binding, and it was very unsafe. When lifting heavy objects, the binding ropes were generally thick and heavy, which was very inconvenient for manual operation. , resulting in lower efficiency of the entire production process. Existing slings cannot meet the lifting requirements of these special materials, and there are still many problems such as low efficiency, unsafety, and easy damage to objects.

Contents of the invention

In order to solve the above problems, according to the structural characteristics of the balance beam, the new model provides a hoisting tool for hoisting large steel pipes, which replaces manual binding and satisfies the needs of on-site processing.

In order to achieve the above purpose, the following technical solutions are adopted:

A hoisting tool for hoisting large steel pipes, consisting of two hooks, two telescopic cylinders and a hanging beam, the hooks are composed of a vertical connection part and a vertical connection part arranged at the end of the connection part The hook portion of the two hooks is formed, and the connecting parts of the two hooks are spliced on both sides of the suspension beam in a mirror image; the two telescopic cylinders are respectively connected to the two suspension hooks with the suspension beam; the telescopic The cylinder base of the cylinder is rotatably connected to the connecting ear on the surface of the suspension beam, and the telescopic rod is rotatably connected to the connecting ear on the upper end of the hook connection part.

The simple and convenient sling can control the expansion and contraction of the telescopic cylinder so that the hook can rotate left and right to hook up heavy objects or release heavy objects.

When in use, the hanging beam is hung by a crane, and the two hooks are moved to both ends of the steel pipe. Control the telescopic cylinder, the telescopic rod is extended, and the hook rotates to the inside of the suspension beam under the action of the telescopic cylinder, so that the hook part of the hook extends into both ends of the steel pipe, and the steel pipe can be hoisted by operating the crane to pull upward. When reaching the designated position, put down the steel pipe, operate the telescopic cylinder, the telescopic rod will shrink, the hook will rotate to the outside, and the hook part of the hook will be separated from the steel pipe to complete a lifting process.

Further, the connecting parts of the two hanging hooks are connected to the ends of the hanging beams through springs. When hoisting, the spring is in an extended state to prevent accidents caused by the steel pipe falling off from the hook when the telescopic cylinder fails.

Further, the hanging beam is symmetrically opened with two long slots, and the connecting parts of the two hanging hooks are hinged to the inner wall of the long slots through a rotating shaft.

Further, the connection between the hook connection part and the hook part is provided with reinforcing ribs.

Further, the surface of the hook part of the hook is provided with an anti-slip strip to prevent the steel pipe from slipping during the lifting process.

The beneficial effect of the present invention is that the structure is simple, practical and light, saves the strapping time, improves the work efficiency, has high safety, and reduces the damage of lifting objects.

Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

As shown in Figure 2-4, a hoisting tool for hoisting large steel pipes is composed of two hooks 3, two telescopic cylinders 4 and a hanging beam 2, the hook 3 is composed of a vertical connecting part It is composed of a hook part arranged at the end of the connecting part and perpendicular to the connecting part, and the connecting parts of the two described suspension hooks 3 are hinged on both sides of the suspension beam 2 in a mirror image; the two telescopic cylinders 4 respectively connect the two The first described suspension hook 3 is connected with the suspension beam 2; the cylinder base of the telescopic cylinder 4 is rotatably connected to the connection ear on the surface of the suspension beam 1, and the telescopic rod is rotatably connected to the connection ear on the upper end of the connection portion of the suspension hook 3.

By controlling the expansion and contraction of the telescopic cylinder 4, the hook 3 can be rotated left and right to pick up or release the steel pipe 1.

During use, the suspension beam 2 is hung by a crane, and the two suspension hooks 3 are moved to both ends of the steel pipe 1.

The initial state is shown in Figure 2. At this time, the telescopic cylinder 4 is controlled, the telescopic rod is extended, and the hook 3 rotates to the inside of the suspension beam 2 under the action of the telescopic cylinder 4, so that the hook portion of the suspension hook 3 extends into both ends of the steel pipe 1, As shown in Figure 1. The steel pipe 1 can be hoisted by operating the crane to pull up. When arriving at the designated position, put down the steel pipe 1, operate the telescopic cylinder 4, the telescopic rod shrinks, the hook 3 rotates to the outside, and the hook portion of the hook 3 breaks away from the steel pipe 1, as shown in Figure 3, a lifting process is completed.

In some embodiments, the connecting parts of the two hanging hooks 3 are both connected to the end of the hanging beam 2 through a spring 5 . When hoisting, the spring 5 is in an extended state to prevent the telescopic cylinder 4 from falling off from the hook 3 and causing an accident.
