Description

Technical Field

[0001] The utility model relates to the technical field of sling devices, in particular to a pipe sling of a crane. Background Art

[0002] Cranes are mechanical equipment used to carry heavy objects. Pipe fittings are commonly used components in industrial production, and their handling and installation are also one of the common tasks of cranes. In order to effectively carry pipe fittings, pipe lifting equipment is required to ensure safety and efficiency.

[0003] Pipe lifting equipment usually consists of a clamp or a jaw to fix the pipe and lift it. However, a traditional lifting equipment has an obvious defect, that is, there is only one clamp or a jaw, which can only clamp the center of the pipe to maintain the balance and stability of the pipe lifting process. For long pipes, it is difficult to accurately grasp the center position, which makes the pipe easy to lose balance or even become unstable, which may cause the pipe to fall and be damaged. Utility Model Content

[0006] 2. Technical Content

[0007] In order to solve the above technical problems, the technical solution of the utility model is: a pipe lifting device for a crane, comprising a crossbeam, a triangular plate connected to the crane hook is fixedly provided on the upper end of the crossbeam, two T-shaped sliders are slidably connected to the bottom surface of the crossbeam, a two-way driving mechanism for driving the two T-shaped sliders to move closer to or away from each other is fixedly provided at the bottom of the crossbeam, a mounting plate is fixedly provided at the bottom of the T-shaped slider, pipe clamps are hingedly provided on the front and rear sides of the bottom of the mounting plate, an electric push rod is fixedly provided at the center of the bottom of the mounting plate, and two connecting rods are hingedly provided at the piston end of the electric push rod, and the other ends of the two connecting rods are respectively hinged to the two pipe clamps.

[0008] Furthermore, a T-shaped slide groove is provided at the bottom of the cross beam, a T-shaped slider is slidably arranged inside the T-shaped slide groove, and two T-shaped sliders are symmetrically slidably arranged on the left and right sides of the center of the cross beam.

[0009] Furthermore, the bidirectional drive mechanism includes vertical plates fixed at both ends of the bottom of the beam, a bidirectional screw rod is rotatably arranged between the two vertical plates, a motor for driving the bidirectional screw rod to rotate is fixedly arranged on the outer side of one of the vertical plates, and the bidirectional screw rod passes through two T-shaped sliders and is threadedly connected to the T-shaped sliders.

[0010] Furthermore, the pipe clamp includes a straight plate hinged to the bottom of the mounting plate and a folding plate fixed to the bottom of the straight plate, the other end of the connecting rod is hinged to the side of the straight plate, and the two folding plates under the same mounting plate are mirror images of each other.

[0011] Three technical effects

[0012] Compared with the prior art, the utility model has the following advantages: by introducing a bidirectional drive mechanism and multiple clamps, the defects of the traditional hoist are effectively solved. The bidirectional drive mechanism can make the two clamps move closer or farther away from each other, so as to adapt to pipes of different lengths, and keep the balance of the pipes through a symmetrical design. The setting of multiple clamps allows the pipes to be clamped in a wider area, increasing the possibility of the pipes being stably lifted, thereby improving the safety and efficiency of the handling process. This improvement improves the quality and efficiency of pipe handling operations and reduces potential safety risks and damage risks. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Through the above structural design, when the utility model is in use, first connect the external power supply, connect the triangle plate 2 with the hook of the crane, and when in use, adjust the distance between the two pipe clamps 5 according to the length of the pipe. Specifically, start the two-way driving mechanism to drive the two T-shaped sliders 3 to move closer to or away from each other, thereby driving the two pipe clamps 5 to move closer to or away from each other, so as to achieve the purpose of adjusting the distance between the two pipe clamps 5. After the adjustment is completed, start the electric push rod 6. Under the action of the connecting rod 7, the two pipe clamps 5 are opened, and then the pipe clamps 5 are lowered to the pipe, and the piston rod of the electric push rod is retracted to prompt the two pipe clamps 5 to clamp the pipe, and then the lifting can be completed by operating the crane's hook to rise.

[0025] In this embodiment, the bidirectional driving mechanism includes vertical plates 9 fixed at both ends of the bottom of the beam 1, and a bidirectional screw rod 10 is rotatably provided between the two vertical plates 9.

[0026] Through this structure, when the distance between the two pipe clamps 5 needs to be adjusted, the motor 11 is started to drive the bidirectional screw 10 to rotate, thereby driving the two T-shaped sliders 3 to move closer to or away from each other. It should be noted that the two T-shaped sliders 3 are symmetrically distributed on both sides of the center of the bidirectional screw 10, and the T-shaped sliders 3 slide inside the T-shaped slide groove 8, and the T-shaped sliders 3 play a load-bearing role in the T-shaped slide groove 8.

The other end of the connecting rod 7 is hinged to the side of the straight plate 12. The two folding plates 13 under the same mounting plate 4 are mirror images of each other.

[0028] Through this structure, the two mirror-image folding plates 13 can adapt to pipes of different diameters. Compared with arc-shaped clamping plates, this design is more practical.

The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
