Description

An adjustable large steel pipe spreader

technical field

The invention relates to the technical field of lifting heavy objects, in particular to an adjustable large-scale steel pipe hanger.

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 special materials such as cylinders, and there are many problems such as low efficiency, unsafety, and easy damage to objects. Moreover, the functional structure of conventional slings is fixed, which is not conducive to widespread promotion and popularization.

Contents of the invention

In order to solve the above problems, according to the structural characteristics of the sling, this new model provides a simple and convenient sling, which replaces manual binding, and can well meet the needs of special materials such as lifting cylinders.

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

An adjustable large-scale steel pipe hanger is composed of a hanging beam and two hooks mirrored at both ends of the hanging beam. The hanging hook is composed of a vertical connecting part and a The vertical hook part is composed of a screw drive device installed in the hanging beam, and the two hook connecting parts are connected with the screw drive device, and move toward each other or back under the control of the screw drive mechanism.

During operation, the hoisting of steel pipes of different lengths is accomplished by controlling the motor to adjust the distance between the two hooks.

Further, the inside of the hanging beam has a cavity for accommodating the screw drive mechanism, and the bottom surface of the cavity has a long groove for the hook to move; the screw drive mechanism is installed on one side of the cavity The motor and the screw rods at both ends are rotatably connected to the two ends of the cavity through bearings; the hook connection part is fixedly connected with the sliding mechanism, and the sliding mechanism is connected with the screw rod.

The crane hangs the beam and moves the two hooks to both ends of the steel pipe. By controlling the rotation of the motor at one end of the hanging beam, the screw rod rotates, and then the sliding mechanism moves in the cavity inside the hanging beam. When the motor is controlled to rotate the screw rod clockwise, the two moving sliding devices will drive the hook to face each other. Move, so that the hook of the hook extends into both ends of the steel pipe, operate the crane to pull up, and then the steel pipe can be lifted. When the designated position is reached, put down the steel pipe, and when the control motor makes the screw rotate counterclockwise, the two moving sliding devices will drive the hook to move back together, and the hook part of the hook will be separated from the steel pipe to complete a lifting process.

Further, the sliding mechanism includes a sliding block sleeved on the screw rod, and pulleys arranged at the upper and lower ends of the sliding block; the inner wall of the cavity is provided with a chute that cooperates with the pulley.

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 anti-slip strips.

The beneficial effect of the present invention is that the structure is simple, practical and light, saves the strap binding time, improves work efficiency, reduces damage to objects, and is convenient for disassembly and replacement. At the same time, it can be used for hoisting steel pipes of different lengths, has a wide application range, and is conducive to promotion and popularization.

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 1-2, an adjustable large-scale steel pipe hanger is composed of a hanging beam 1 and two hooks 2 mirrored at both ends of the hanging beam 1. The hanging hooks 2 are connected by vertical part 21 and the hook part 22 which is arranged at the end of the connecting part 21 and is perpendicular to the connecting part 21. The screw drive device is installed inside the hanging beam 1, and the two connecting parts 21 of the hanging hook 2 are driven by the screw rod. The devices are connected, and under the control of the screw drive mechanism, they move toward each other or back.

During operation, the hoisting of steel pipes of different lengths is accomplished by controlling the motor to adjust the distance between the two hooks.

As the most preferred embodiment of the present invention, the inside of the hanging beam 1 has a cavity 3 for accommodating the screw drive mechanism, and the bottom surface of the cavity 3 has a long groove 31 for the hook to move; the wire The rod transmission mechanism is composed of a motor 4 installed on one side of the cavity 3 and a screw rod 5 whose two ends are rotatably connected to the two ends of the cavity 3 through bearings; the connecting part 21 of the hook 2 is fixedly connected with the sliding mechanism, and the Sliding mechanism links to each other with screw mandrel 5.

The crane hangs the beam and moves the two hooks to both ends of the steel pipe. By controlling the rotation of the motor at one end of the hanging beam, the screw rod rotates, and then the sliding mechanism moves in the cavity inside the hanging beam. When the motor is controlled to rotate the screw rod clockwise, the two moving sliding devices will drive the hook to face each other. Move, so that the hook portion of the hook extends into both ends of the steel pipe, and the steel pipe can be lifted by operating the crane to pull upward. When the designated position is reached, put down the steel pipe, and when the control motor makes the screw rotate counterclockwise, the two moving sliding devices will drive the hook to move back together, and the hook part of the hook will be separated from the steel pipe to complete a lifting process.
