Description

Technical Field

[0001] The utility model relates to the technical field related to slings, and in particular to a slewing bearing transport sling. Background Art

[0002] Slewing bearings are also called turntable bearings, also called rotating bearings or rotary bearings. Slewing bearings are widely used in real industry and are called "machine joints". They are important transmission components required for machines that need to make relative rotational motion between two objects and need to bear axial force, axial force, and overturning moment at the same time.

[0003] During the machining process of the slewing bearing, due to its own product characteristics, it needs to go through multiple processes to complete. These processes include rough turning, semi-finishing turning, finishing turning, grinding, assembly and other processes. The change of processing procedures requires the slewing bearing to be repeatedly hoisted. At present, the hoisting equipment of the slewing bearing is a crane, and the hoisting device mainly adopts a traditional hook. Therefore, in the traditional hoisting process, although the hook can realize the hoisting operation of the slewing bearing, there is a risk of decoupling, so there are certain safety hazards;

[0004] Therefore, based on the above problems, the present invention provides a slewing bearing transport sling. Utility Model Content

[0026] Example

[0027] In order to solve the technical problems in the background technology, a slewing bearing transfer hanger is provided as follows:

[0028] Combination Figure 1-4As shown, the utility model provides a slewing bearing transport sling, comprising an upper plate 14, a triangular sling plate 1 is fixedly arranged on the top surface of the upper plate 14, and a sling hole is opened on the triangular sling plate 1. A plurality of fixed blocks 15 are evenly fixedly arranged on the bottom surface of the upper plate 14, a lower plate 12 is arranged below the upper plate 14, a plurality of bottom plates 10 are evenly fixedly arranged on the lower plate 12, and a plurality of support rods 2 are evenly and movably hingedly arranged between each bottom plate 10 and the corresponding fixed block 15;

[0029] A central column 3 is fixedly arranged between the upper plate 14 and the lower plate 12, a limiting slide cylinder 4 is slidably sleeved on the central column 3, and a matching adjustment component 9 is arranged between the limiting slide cylinder 4 and the upper plate 14;

[0030] A limiting ring is fixedly sleeved on the limiting slide cylinder 4, a matching slider 8 is provided on each bottom plate 10, an adjusting rod 6 is movably hinged between each matching slider 8 and the limiting ring, and an electromagnetic suction cup 11 is fixedly provided at the bottom end of each matching slider 8.

[0031] The matching adjustment component 9 includes a guide cylinder 92 and a drive motor 94. The guide cylinder 92 is fixedly arranged on the upper plate 14. An L-shaped guide rod is arranged in the guide cylinder 92. The L-shaped guide rod is fixedly connected to the limiting slide cylinder 4. One side of the L-shaped guide rod rises and falls along the guide cylinder 92. A rack plate 91 is fixedly arranged on the other side of the L-shaped guide rod. The drive motor 94 is fixedly installed on the upper plate 14. A rotating shaft is fixedly arranged at the power output end of the drive motor 94. One end of the rotating shaft away from the drive motor 94 extends into the guide cylinder 92 and is fixedly arranged with an adjusting gear 93. The adjusting gear 93 is meshed and connected with the rack plate 91.

[0032] As a further improvement of the above technical solution, a guide bar is fixedly mounted on the L-shaped guide rod, and a guide slot matching the guide bar is provided on the inner wall of the guide cylinder 92. The matching arrangement of the guide bar and the guide slot helps to increase the stability of the L-shaped guide rod in lifting and sliding along the guide cylinder 92, thereby increasing the stability of the overall device and further improving the stability of the slewing bearing in the later stage of hoisting and transporting.

[0033] A control console 7 is fixedly mounted on the central column 3 , and a controller is mounted on the control console 7 . The controller is electrically connected to the electromagnetic chuck 11 .

[0034] A linear guide rail 13 is fixedly disposed on the bottom plate 10 , and the matching slider 8 is slidably disposed on the linear guide rail 13 .

[0035] Two limit blocks 81 are fixedly disposed on the inner side of the matching slide block 8 , and a limit sliding groove 131 matching with the limit blocks 81 is formed on the linear guide rail 13 .

[0036] In specific use, when the slewing bearing needs to be hoisted and transported, the hoist can be adjusted according to the diameter of the slewing bearing to facilitate hoisting and transportation in the later stage. The operation is as follows:

[0037] Start the drive motor 94. Under the power output of the drive motor 94, the rotating shaft and the adjusting gear 93 are driven to rotate synchronously. At the same time, under the meshing operation, the rack plate 91 is driven to slide and lift along the guide cylinder 92, and then the limit slide cylinder 4 is driven to slide and lift along the center column 3. At the same time, under the articulation operation, the two ends of each adjusting rod 6 are driven to be movably articulated along the corresponding matching slider 8 and the limit ring, and then each matching slider 8 is driven to slide and move along the corresponding linear guide rail 13, thereby driving a number of electromagnetic suction cups 11 to be adjusted synchronously (to achieve the purpose of expanding or reducing the lifting diameter). When the slewing bearing needs to be lifted, the controller controls a number of electromagnetic suction cups 11, and the magnetization and demagnetization operations can be performed by powering on. The operation steps are as follows: the lifting device is adjusted to a suitable lifting diameter, and the lifting device is moved to the top of the workpiece and in contact with the workpiece by a crane. Power is turned on for magnetization (the sling attracts the workpiece), the workpiece is moved to the target area by a crane, power is turned on for demagnetization (the sling releases the workpiece), and the sling is removed to complete the lifting. In this way, the present invention, through the coordinated arrangement between various structures, is not only convenient for flexible adjustment of the sling according to the diameter of the transfer slewing bearing, and is convenient for the transportation of slewing bearings of different diameters, but also the suction cup adopts an electromagnetic suction cup 11, which is electrically adsorbed and released when power is off, which is convenient for automated lifting, improves production efficiency, and reduces manual labor. At the same time, the number of support rods 2 and adjustment rods 6 are all three, and the three support rods 2 and the three adjustment rods 6 all form a triangular bracket structure with the central column 3. Since the triangle has stability, it is beneficial to increase the stability of the transfer sling when transporting the slewing bearing, and to improve the stability of the overall device, which is convenient for the later transportation of the slewing bearing, and makes the lifting more stable and safe.
