Problems solved by technology

[0003] If there is no special tooling equipment for large workpieces, it is difficult to achieve them only by manpower. Many current solutions are to use cranes or multiple hooks to cooperate with the operation. Improper coordination and improper lifting methods often cause accidents such as workpiece fal

specific Embodiment 1

[0049] Such as figure 1 As shown, a device that utilizes a rack and pinion to realize the lifting and turning of a large workpiece includes a frame 1, a drive system 2, a lifting mechanism 3, a turning mechanism 4, a locking mechanism 5, a turning platform 6 and a PLC control system 7, and the frame 1 Respectively by the first support frame 12 and the second support frame 13, the drive system 2 is arranged at the bottom of the frame 1, the number of lifting mechanisms 3 has two groups, respectively arranged on the first support frame 12 and the second support frame 13, The overturning mechanism 4 is arranged on the first supporting frame 12, the overturning platform 6 is connected to the slider 34 through the slewing bearing 61, and the PLC control system 7 is electrically connected with the drive system 2, the overturning mechanism 4 and the locking mechanism 5 respectively.

[0050] Such as figure 2 As shown, the drive system 2 includes a motor 21 and a speed reducer 22 co...

Embodiment 2

[0075] On the basis of Embodiment 1, wherein the driving system 2 can be replaced by a hydraulic system, it is not limited to a power supply method.

Embodiment 3

[0077] On the basis of Embodiment 1, the number of lifting mechanisms 3 can be no less than two groups of even groups, and are symmetrically distributed on the first support frame 12 and the second support frame 13, which can be increased according to actual production work, so that It is more stable and has a larger load when it operates (rising or turning).

Abstract

The invention discloses a device for realizing lifting and overturning of a large workpiece through a gear and a rack. The device is characterized by comprising the rack, a driving system, a lifting mechanism, an overturning mechanism, a locking mechanism, an overturning platform and a PLC control system. By means of the device, lifting and overturning of the large workpiece can be realized, electrical automatic operation control can be realized, operators can be far away from equipment and operate in a safe area, and harm to the operators can be avoided.

Description

technical field [0001] The invention belongs to the technical field related to mechanical processing, and in particular relates to a device for realizing lifting and turning of a large workpiece by using a rack and pinion. Background technique [0002] With the development of social economy and the progress of industrial manufacturing, the development of large-scale equipment manufacturing is accelerating, so the demand for tooling in the manufacturing process of large-scale equipment continues to increase. Nowadays, many large-scale equipment are welded, but welding stress deformation is unavoidable. At present, in order to weaken the influence of welding stress deformation on workpieces, many welding processes have been compiled. Among them, the most effective method for large workpieces is welding. During the process, if welding deformation is found, stop welding, and then turn over the workpiece and start welding from the other side to offset the welding deformation caus...
