Description

Technical Field

[0001] The utility model mainly relates to the technical field of ring clamping tooling, in particular to a sling auxiliary tooling for large-diameter rings. Background Art

[0002] In the manufacturing process of large-diameter rings, hot forming and heat treatment are essential processes. The former affects the dimensions of the final product, while the latter affects its performance. The correct selection and implementation of hot forming and heat treatment processes are crucial to ensuring the performance of the workpiece in actual use.

[0003] However, large-diameter annular workpieces are prone to gravity deformation in a hot state. In the existing technology, when performing hot processing on large-diameter annular workpieces, it is necessary to fix them by evenly arranging multiple sets of hooks in a ring shape at the bottom of the annular workpiece. After being fixed by the hooks, they are lifted and transported using wire ropes in combination with lifting equipment. The use of hooks for fixing is prone to uneven force during lifting, and is prone to sagging due to gravity. Moreover, the hooks have a small contact area, resulting in greater pressure, which will scratch the hot ring itself, and the upper wire rope will also cause strangulation to the ring. In order to process the surface, the amount of cutting in subsequent machining has to be increased, resulting in material waste and extended construction period. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the present invention provides a sling auxiliary tooling for large diameter rings, which is achieved through the following technical solutions:

[0014] Furthermore, the limiting assembly includes a rotating shaft, and the rotating shaft is respectively installed with bearings at the front and rear ends of the fixing frame.

DETAILED DESCRIPTION

[0027] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalent forms also fall within the scope defined in this application.

[0028] Example: A lifting aid for large diameter rings

[0029] like Figure 1-5 As shown, a lifting auxiliary tooling for large diameter rings, the specific structure of which includes:

[0030] The support frame 10, the crossbeam 20, the suspension assembly 30, and the clamping assembly 40 are characterized in that: the support frame 10 is slidably mounted on both sides of the bottom surface of the crossbeam 20, the interior of the crossbeam 20 is hollow and both ends are open, the bottom surface of the crossbeam 20 is provided with a through groove 201, the bottom of the support frame 10 is fixedly mounted with the suspension assembly 30, the lower end of each suspension assembly 30 is provided with a clamping assembly 40, and the ring 60 can be fixed between the clamping assemblies 40;

[0031] Wherein, the suspension assembly 30 includes:

[0032] A connecting frame 301 is fixedly mounted on the bottom of the support frame 10;

[0033] Extension plates 302 are fixedly mounted on the lower ends of the connecting frames 301 , and clamping assemblies 40 are fixedly mounted on the lower ends of the extension plates 302 .

[0034] The clamping assembly 40 includes: a fixing frame 401, the fixing frame 401 is fixedly installed at the lower end of the extension plate 302; a wing plate 402, the wing plates 402 are rotatably installed on the front and rear sides of the fixing frame 401; a supporting wheel 403, the bottom surface of the wing plate 402 is rotatably installed on the supporting wheel 403; the inner side of the fixing plate 401 is provided with a limiting assembly 50 that can drive the wing plate 402 to rotate.

[0035] The above working principle: When the device is in use, the entire device is moved above the ring member 60 to be hoisted.

[0036] The distance between the two suspension components 30 is adjusted by moving the support frame 10, thereby achieving the adjustment of the position of the clamping component 40; when the clamping component 40 is aligned with the ring, the entire device is lowered and the clamping components 40 are brought close together so that the supporting wheel 403 is located below the ring 60, and an external crane or similar lifting equipment is used to slowly lift the device so that the supporting wheel 403 contacts the bottom of the ring 60, thereby lifting the ring 60 upward.

[0037] The limiting assembly 50 includes a rotating shaft 501, with bearings mounted on the front and rear ends of the fixing frame 401. Wings 402 are fixedly mounted on the outer sides of the rotating shaft 501. Tension springs 502 are fixedly mounted on the upper portions of the front and rear ends of the fixing frame 401, with one end of each tension spring 502 fixedly connected to the upper portion of the inner side of the corresponding wing 402. When the device is in use, when the wing 402 at each end of the fixing frame 401 contacts the outer side of the ring 60, the wing 402 will expand outward due to the squeezing effect of the ring 60 until the support wheel 403 is tightly attached to the inner side of the ring.

[0038] The minimum unfolding angle of the wing plate 402 relative to the fixing frame 401 is 45 degrees. By setting the design of the wing plate 402 rotating at a certain angle, the device can be applied to large rings of different diameters and shapes while providing sufficient grip to prevent sliding.

[0039] A reduction motor is fixedly installed at both ends of the beam 20, and the reduction motor is electrically connected to the power supply. Chain drive assemblies are symmetrically installed on both sides of the beam 20, and the chain drive assemblies are respectively controlled to rotate by the corresponding reduction motors. The connecting frames 301 are respectively fixedly connected to the corresponding chain drive assemblies, and the chain drive assemblies can respectively drive the corresponding connecting frames 301 to move horizontally.

[0040] The chain transmission assembly includes a synchronous wheel and a synchronous drive. Two sets of matching synchronous wheels are installed on both sides of the interior of the crossbeam 20. The synchronous wheels on the same side are connected through one of the synchronous drives, and the reduction motor drives one of the synchronous wheels on the same side to rotate.

[0041] This solution also includes a controller, the position of which is set by the staff according to actual conditions during operation. The controller is used to control the electrical devices used in this solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, display screens, computer input devices, switch buttons, communication equipment, lights, speakers and microphones; the controller is an Intel processor, AMD processor, PLC controller, ARM processor or a single-chip microcomputer, and the supporting components also include a motherboard, memory stick, storage medium and power supply, and the power supply is AC or lithium battery; when a display screen is provided, a display card is also provided; for the operating principle of the controller, please refer to "Principles of Automatic Control", "Microcontroller Principles and Application Simulation Cases" and "Sensor Principles and Applications" published by Tsinghua University Press, and other books in this field can be used for reference; other automatic controls and electrical devices not mentioned are all knowledge well known to those skilled in the art and will not be repeated here.

[0042] In the interpretation of the present invention, it should be noted that the terms indicating orientation are only for the convenience of description and understanding, and are not the only limitation on the installation position of specific technical features, and do not exclude other possible installation methods.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
