[0009] The beneficial effects of the utility model are as follows: the sling is adjusted according to the position of the center of gravity of the machine tool and connected to the corresponding first adjustment hole, so that the point of action of the sling tension and the center of gravity of the machine tool remain in the same straight line; the sling is adjusted according to the size of the machine tool and connected to the corresponding second adjustment hole; the operation is simple, only one sling is needed to adapt to machine tools of different models, and the cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic diagram of the structure of the utility model;
[0011] Figure 2 The schematic diagram is a structural example of adjusting the tension application point of the sling. DETAILED DESCRIPTION
[0012] In order to better understand the concept of the present invention, the technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0013] The technical solution of the utility model is as follows: a lifting device for a machine tool crane, such as Figure 1 As shown, it includes a lifting ring 1 and a balance beam 2, the lifting ring is hung on a crane, two groups of first adjustment holes 3 arranged along the length direction of the balance beam 2 are symmetrically arranged at the center of the balance beam on the upper part of the balance beam 2, at least two slings 4 hung on the lifting ring are arranged on the lifting ring 1, each sling 4 is respectively connected to any one of the first adjustment holes 3 in each group, and each sling is connected to any one of the first adjustment holes in its corresponding group, according to the positions of the two groups of adjustment holes on the balance beam, the sling is connected from the lifting ring to the balance beam in a herringbone shape, because the center of gravity of each machine tool is different, the first adjustment hole connected by the sling is adjusted according to the center of gravity of the machine tool, so that the point of action of the sling tension and the center of gravity of the machine tool remain in the same straight line, for example, when the center of gravity of the machine tool is biased to the left, as shown in FIG. Figure 2 As shown, the two slings are respectively adjusted to the first first adjustment hole in each group of first adjustment holes corresponding to each sling (each group of first adjustment holes is arranged from left to right), so that the point of action of the sling tension is moved to the center of gravity of the machine tool to keep the machine tool stable.
[0014] Since each machine tool has different dimensions, Figure 1 As shown, two groups of second adjustment holes 5 are symmetrically arranged along the length direction of the balance beam 2 at the lower part of the balance beam with the center of the balance beam, each group of second adjustment holes 5 includes two rows of second adjustment holes 5 arranged in parallel, and a lifting rope 6 for hanging the machine tool is switchably connected between each row of the second adjustment holes 5. The tail of the lifting rope is a hook that can hang the machine tool. There are four rows of second adjustment holes and four lifting ropes. The four lifting ropes are first connected to the machine tool, and then each lifting rope is connected to the corresponding second adjustment hole. The above structure enables the sling to adapt to machine tools of different sizes.
[0015] In order to ensure the stability of the balance beam suspension, the two slings connected to the lifting ring are increased to four slings, and each group of first adjustment holes 3 includes two rows of first adjustment holes 3 arranged in parallel, that is, a total of four rows of first adjustment holes, and each sling 4 is respectively connected to any one of the first adjustment holes 3 in each row to increase the pulling force of the sling.
[0016] Due to the inconsistency of the machine tool shapes, the positions on the machine tool and the connection with the lifting rope are not at the same level, so the length of the lifting rope needs to be adjusted. A telescopic member 7 capable of adjusting the length of the lifting rope 6 is provided on the lifting rope 6. In this embodiment, the telescopic member is a turnbuckle screw. The length of the turnbuckle screw is adjusted to adjust the length of the lifting rope, thereby adjusting the center of gravity of the machine tool, so that the lifting of the machine tool remains stable. Figure 1 In order to save costs, turnbuckle screws are provided on two suspension ropes, or turnbuckle screws are provided on all four suspension ropes.
[0017] In order to facilitate the installation and disassembly of the sling and the sling rope, the sling 4 and the sling rope 6 are respectively connected to the first adjustment hole 3 and the second adjustment hole 5 through the shackle 8, the pin of the shackle arranged in the first adjustment hole passes through the first adjustment hole, the bent ring of the shackle is connected to the sling, and the pin of the shackle arranged in the second adjustment hole passes through the second adjustment hole, and the bent ring of the shackle is connected to the sling.
[0018] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
