Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a large-span clamp crane. Background Art

[0002] A large-span clamp crane is a device used for transporting and handling across large distances. It is usually supported by a cross-type bridge frame, on which clamps or fixtures are installed, which can move in the horizontal direction and are used to clamp and move various objects. This large-span clamp crane can effectively improve the efficiency of material handling and is particularly suitable for occasions that require cross-span movement over a large distance, such as large warehouses, production workshops, etc. It has the characteristics of solid structure, simple operation, safety and reliability, and can help enterprises improve work efficiency, reduce labor costs, and enhance competitiveness.

[0003] A large-span clamp crane is disclosed in the Chinese utility model patent application disclosure CN213537044U. Although the utility model is used to solve the problems in the prior art that the clamp crane has insufficient lifting stability and the clamp is prone to shaking and unhooking, thereby affecting production safety and production efficiency, when adjusting the angle of the clamp, the staff needs to swing the hook back and forth and left and right to stabilize it, which is not convenient for quickly adjusting the clamp to the corresponding position, and has the disadvantage of poor convenience. Utility Model Content

[0012] The utility model provides a large-span clamp crane, which has the following beneficial effects:

[0013] 1. This large-span clamp crane has the effect of facilitating the adjustment of the clamp posture of the clamp body through the arrangement of a multi-stage electric telescopic rod, a fixed ring, an annular slider, a gear ring, a connecting rod, a push plate and an electromagnet. When in use, the mobile trolley drives the clamp body to rise and fall through a steel wire rope. When the clamp body moves to the cargo, when the clamp angle of the clamp body deviates, when adjusting the clamp body, the staff controls the telescopic end of the multi-stage electric telescopic rod to extend outward, drives the fixed ring to move downward through the multi-stage electric telescopic rod, moves the fixed ring to the top of the clamp body, and then controls the output end of the servo motor to rotate, drives the active gear to rotate through the servo motor, and the active gear drives the The gear ring is moved to make the annular slider on the inner side of the gear ring slide in the annular groove, thereby playing the role of making the gear ring rotate. While the gear ring rotates, the push plate is driven to approach the clamp body through the connecting rod, so that the push plate on the push plate surface contacts the side of the clamp body. After contact, the electromagnet is energized, and the electromagnet and the clamp body are magnetically attracted together through the electromagnetism. Then the gear ring is continued to be controlled to rotate, and the clamp body is driven to rotate through the connecting rod, push plate and electromagnet until the clamp body is rotated to the clamp angle suitable for the cargo. After completion, the next step of work can be carried out. The clamp crane can quickly adjust the clamp posture of the clamp body, so as to improve the clamp efficiency and achieve the purpose of improving the convenience of use of the clamp crane.
