Description

Technical field:

[0001] The utility model relates to the field of mechanical processing equipment, in particular to a flexible workpiece hanger. Background technology:

[0002] The covering parts of trains, cars, etc. are usually made by cutting and processing thinner plates such as aluminum plates and iron plates. The plates used in processing are long, and due to their thinness and softness, they are easy to bend and deform during hoisting, which is inconvenient to transport. It is usually necessary to make a support frame for supporting the workpiece to prevent the plate from bending and being damaged during transportation; but the overall size and weight of the support frame are large, and the frequent transportation at the work site has poor flexibility, resulting in low transportation efficiency, which slows down the efficiency of production and processing. Utility model content:

[0003] The utility model aims to provide a flexible workpiece hanger to solve the problems existing in the prior art.

[0004] The utility model is implemented by the following technical scheme: a flexible workpiece hanger, including a hanger, a sliding ring, a lifting rope and a hook. A plurality of sliding rings are slidably provided on the crossbeam of the hanger. The sliding ring includes a slider and a lifting arm. The crossbeam is a hollow square tube. A guide groove is longitudinally opened on the bottom surface of the crossbeam. The slider is slidably placed in the crossbeam. The bottom of the slider is fixedly connected to a lifting arm. The lifting arm passes through the guide groove at the bottom of the crossbeam and is fixedly connected to the lifting rope. Two lifting ropes are fixedly connected to each lifting arm, and a hook is fixedly connected to the lower end of each lifting rope.

[0005] Furthermore, the lifting ring also includes a positioning plate and an indexing pin. A plurality of positioning holes are opened on the side wall of the beam along the length direction. The positioning plate is integrally formed on the lifting arm, and an indexing pin is fixedly installed on the positioning plate at a height corresponding to the positioning hole.

[0006] Furthermore, the hook includes a clamping claw and a hanging plate, the clamping claw is in a "C" shape with one side open, the top of the clamping claw is hinged to the hanging plate, and the hanging plate is fixedly connected to the lifting rope.

[0007] Furthermore, a rubber pad is clamped inside the clamping claw of the hook.

[0008] Furthermore, the hanger includes a cross beam, an inclined arm, a hanging plate and reinforcing ribs. Two inclined arms are symmetrically arranged on the top surface of the cross beam. The two ends of the cross beam are respectively fixedly connected to one end of the inclined arm. The other ends of the two inclined arms are fixedly connected to each other above the cross beam. A number of reinforcing ribs are symmetrically fixedly connected between the two inclined arms and the cross beam. The bottom of the hanging plate is fixed to the top surface of the cross beam. The upper part of the hanging plate passes through the intersection of the two inclined arms and is fixedly connected to the two inclined arms. A hanging hole is opened at the top of the hanging plate.

[0009] Furthermore, legs are fixedly installed at both ends of the beam.

[0010] The advantages of the utility model are as follows: uniform pulling force is applied to each section of the workpiece by means of multiple sets of hooks and ropes arranged on both sides of the workpiece, which can prevent the flexible workpiece from being bent and damaged during lifting. Instead of the traditional method of transporting the workpiece by supporting the support frame, the workpiece can be directly lifted, which improves the efficiency of transportation, and the sliding lifting ring on the crossbeam of the hanger can adjust its position according to the length and shape of the workpiece, so as to be suitable for workpieces of different lengths and shapes.

[0019] like Figure 3 As shown: two lifting ropes 3 are fixedly connected to each lifting arm 202, and a hook 4 is fixedly connected to the lower end of each lifting rope 3. When in use, the two lifting hooks 4 are symmetrically arranged on both sides of the workpiece as a group. When the lifting rope 3 is pulled upward, the lifting rope 3 and the workpiece form a triangular structure, while applying an upward pulling force to the workpiece, the two hooks 4 are simultaneously tightened toward the middle, so that the hooks 4 will not separate from the workpiece; at the same time, multiple groups of lifting hooks 4 are provided, and each group of lifting hooks 4 is evenly distributed in the length direction of the workpiece, so that the flexible workpiece can be lifted as a whole, and multiple groups of lifting hooks 4 apply force at the same time, and each section of the workpiece is evenly stressed, so the workpiece will not be bent or deformed; and the position of the sliding lifting ring 2 can be adjusted by the indexing pin 204, and then the clamping position of the hook 4 can be adjusted according to the length and shape of the workpiece, so as to match workpieces of different lengths and shapes;
