Description

Technical Field

[0001] This utility model relates to the field of lifting and hoisting equipment for CNC machine tools, specifically a lifting block structure for lifting machine tools. Background Technology

[0002] The lifting block of a hoisting machine tool is the core load-bearing component for hoisting and transporting the machine tool. It is mainly used to safely and stably move the equipment. It can serve as a dedicated load-bearing point to transfer the hoisting load to the main frame of the machine tool, protect the precision surfaces of the machine tool from friction by the slings, and prevent damage to non-load-bearing components. At the same time, by rationally arranging and matching the center of gravity of the machine tool, it can prevent tilting or swaying during hoisting.

[0003] The lifting block structure of the existing lifting machine tool only fixes the base and the lifting lug together by welding. The lifting block structure of some existing lifting machine tools is simple, and only the edge connection between the base and the lifting lug is welded. The connection between the base and the lifting lug is not strong enough, which makes the overall structural strength of the lifting block insufficient. Therefore, in order to solve the above problems, a lifting block structure for the lifting machine tool is proposed. Utility Model Content

First weld protrusions are provided between the triangular reinforcing ribs and the base. A lifting lug is provided on the lower side of the base between the two pairs of triangular reinforcing ribs. A positioning protrusion is provided on the upper side of the lifting lug within the positioning groove. Two second threaded holes are provided on the upper side of the lifting lug, directly below the first threaded holes. The base is threadedly connected to a connecting bolt through the first threaded holes, and the lifting lug is threadedly connected to a connecting bolt through the second threaded holes.

[0007] Preferably, the width of the base and the lifting lug are equal in the left and right directions, and the lifting lug and the positioning protrusion are integrally formed castings.

[0008] Preferably, all the triangular reinforcing ribs are welded to the lifting lugs, and a fourth weld protrusion is provided between the triangular reinforcing ribs and the lifting lugs.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0021] A lifting block structure for a lifting machine tool includes a base 1. A positioning groove 2 is provided in the middle of the base 1. First threaded holes 3 are provided on both the left and right sides of the positioning groove 2. Two pairs of triangular reinforcing ribs 4 are welded to the lower side of the base 1. A first weld protrusion 5 is provided between the triangular reinforcing ribs 4 and the base 1. A lifting lug 6 is provided on the lower side of the base 1 between the two pairs of triangular reinforcing ribs 4. A positioning protrusion 7 is provided on the upper side of the lifting lug 6 within the positioning groove 2. Two second threaded holes 8 are provided on the upper side of the lifting lug 6 directly below the first threaded holes 3. The base 1 is threadedly connected to the connecting bolt 9 through the first threaded holes 3, and the lifting lug 6 is threadedly connected to the connecting bolt 9 through the second threaded holes 8.

[0022] The base 1 and the lifting lug 6 are equal in width in the left and right directions. The lifting lug 6 and the positioning protrusion 7 are integrally cast parts. The base 1 and the positioning protrusion 7 can be positioned by the positioning protrusion 7 and the positioning groove 2. The triangular reinforcing ribs 4 are all welded to the lifting lug 6. A fourth weld protrusion 12 is provided between the triangular reinforcing ribs 4 and the lifting lug 6. The triangular reinforcing ribs 4 can support the lifting lug 6 and improve the structural strength of the device. The outer side of the positioning protrusion 7 is attached to the base 1. A second weld protrusion 10 is provided between the positioning protrusion 7 and the base 1. The upper side of the lifting lug 6 is attached to the lower side of the base 1. Two symmetrically distributed third weld protrusions 11 are provided between the lifting lug 6 and the base 1. The first weld protrusion 5, the second weld protrusion 10, the third weld protrusion 11, and the fourth weld protrusion 12 make the connection between the lifting lug 6 and the base 1 more secure.

[0023] Workflow: The base 1 of this device is a pre-produced component, while the lifting lug 6 and positioning protrusion 7 are integrally molded components. During production, the positioning protrusion 7 can be inserted into the positioning groove 2 to position the base 1 and the positioning protrusion 7. Then, the base 1 and the lifting lug 6 are bolted together using connecting bolts 9, which are located in the first threaded hole 3 and the second threaded hole 8. Subsequently, two pairs of triangular reinforcing ribs 4 are welded to the base 1 to form the first weld protrusion 5. Then, the triangular reinforcing ribs 4, which are fixed to the base 1, are welded to the lifting lug 6 to form the fourth weld protrusion 12. Finally, the lifting lug 6 is welded to the base 1. The third weld protrusion 11 is generated, and then the positioning protrusion 7 and the base 1 are welded together to generate the second weld protrusion 10. This device can quickly position the lifting lug 6 and the base 1 through the positioning protrusion 7, and quickly assemble the lifting lug 6 and the base 1 together through the connecting bolt 9. The overall structural strength is strengthened by the triangular reinforcing rib 4. The positioning groove 2, the triangular reinforcing rib 4 and the positioning protrusion 7 provide more welding positions. The first weld protrusion 5, the second weld protrusion 10, the third weld protrusion 11 and the fourth weld protrusion 12 make the connection between the lifting lug 6 and the base 1 more solid, so that the overall structural strength of the structure is significantly improved.
