Description

Technical Field

[0001] This utility model belongs to the field of lifting and hoisting equipment technology, and in particular relates to a lifting tool for steel forging profiles. Background Technology

[0002] Gourd-shaped steel forgings (with a central neck and large diameters at both ends) are very common in forgings, such as ball valve bodies, cross shafts, T-shaped / cross-shaped modules, and double-flange shaft sections. Due to their dumbbell or gourd-like shape, the center of gravity is located at the neck, and the outer diameters at both ends are larger than the neck, making reliable and damage-free gripping and transportation difficult. Existing lifting tools for gourd-shaped steel forgings still have problems with positioning and unstable clamping. For example, the wire rope / sling needs to be manually turned and threaded at the bottom, which poses a risk of slippage and disengagement, and the positioning accuracy is poor, affecting the lifting efficiency of steel forging profiles. Utility Model Content

[0003] In view of this, the present invention aims to propose a steel forging profile lifting tool to solve the problem that existing lifting tools have poor positioning accuracy and affect lifting efficiency when lifting gourd-shaped steel forgings.

[0007] Furthermore, the connector has a pin hole at one end that passes through the connector hole, and the right hanger has a positioning pin that can cooperate with the pin hole. The positioning pin is detachably installed on the right hanger.

[0008] Furthermore, the right hanger is provided with positioning rings for installing positioning pins at positions above and below the corresponding plug-in parts.

[0009] Furthermore, a cushioning pad is provided on the fitting part.

[0010] Furthermore, the cushioning pad is made of rubber.

[0011] Furthermore, both the main lifting ring and the auxiliary lifting ring are connected to the vertical end via a connecting plate.

[0012] Compared with the prior art, the steel forging profile lifting tool of this utility model has the following advantages: This utility model discloses a lifting device for steel forging profiles, applicable to the lifting of steel forging profiles. It features a simple structure, high positioning accuracy, and ease of assembly and use.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] A type of steel forging profile lifting tool, such as Figures 1 to 3 As shown, it includes a left lifting member 1 and a right lifting member 2, with a fitting clearance between the left lifting member 1 and the right lifting member 2 to mate with the steel forging profile; the left lifting member 1 and the right lifting member 2 are detachably connected, and both the left lifting member 1 and the right lifting member 2 include a horizontal end 3, with a recessed portion 5 on the horizontal end 3 corresponding to the fitting clearance position; both the left lifting member 1 and the right lifting member 2 include a vertical end 4, with a fitting portion 6 on the vertical end 4 corresponding to the fitting clearance position; a main lifting ring 9 is provided on the left lifting member 1 and the right lifting member 2 at the position corresponding to the connection between the horizontal end 3 and the vertical end 4; and an auxiliary lifting ring 10 is provided above the vertical end 4 of both the left lifting member 1 and the right lifting member 2.

[0020] Specifically, the shape of the recess 5 can be designed to match the shape of the neck of the steel forging to achieve a better fit and improve the positioning accuracy of the steel forging by this lifting device. Simultaneously, by using the left lifting member 1 and the right lifting member 2 to clamp the steel forging, the horizontal ends 3 of the left and right lifting members 1 and 2 can clamp the neck of the steel forging, while the vertical ends 4 of the left and right lifting members 1 and 2 can clamp other positions of the steel forging. This achieves rapid positioning and clamping of the steel forging. Furthermore, the multi-point clamping and limiting not only further improves the positioning accuracy of the steel forging but also enhances the lifting efficiency and stability during subsequent lifting processes.

[0021] In practical applications, the lifting rope can be passed through the auxiliary lifting ring 10 and connected to the main lifting ring 9. By utilizing the connection and limiting effect of the lifting rope, both the left lifting part 1 and the right lifting part 2 can remain stable during the lifting process, and are not prone to tilting or slipping. This helps to improve the safety and stability of this lifting tool during use, and ensures that the lifting tool can stably lift steel forgings.

[0022] In one optional embodiment, the left lifting member 1 is provided with a connector 8 on both sides of the recess 5, and the right lifting member 2 is provided with a connector hole 15 that mates with the connector 8. By using the connector 8 and the connector hole 15 to mate, the left lifting member 1 and the right lifting member 2 can be detachably assembled. When the lifting rope tightens the main lifting ring 9, it will generate an upward force on the vertical ends 4 of the left lifting member 1 and the right lifting member 2. Under the action of this force, the vertical ends 4 of the two lifting members can further clamp and fix the steel forging except for the neck. The horizontal ends 3 of the two lifting members can be stably connected by the connector 8 and the connector hole 15. At this time, the connector 8 and the inner wall of the connector hole 15 are actually in a butt-fitting fit under the action of the above-mentioned force, and it is not easy to fall out.

[0023] In this embodiment, two connectors 8 are provided on the left and right sides of the recessed portion 5, which helps to improve the stability of the left lifting component 1 and the right lifting component 2 after assembly and ensures the overall structural strength of the lifting device. It should be understood that four, six or more connectors 8 can also be provided on the left and right sides of the recessed portion 5 to distribute the force on a single connector 8 and prevent the lifting device from becoming unstable due to deformation of a single connector 8.

[0024] In one optional embodiment, the connector 8 and the left lifting member 1 are threadedly connected. The left lifting member 1 has a threaded hole for installing the connector 8. One end of the connector 8 extending into the threaded hole has a connecting groove 17, and the other end has a plug-in portion 13 that mates with the plug-in hole 15. The connecting groove 17 can be a rectangular groove, an internal hexagonal groove, or other structures, and can be used to connect tools such as handles and rotating rods. In practical applications, the operator can insert a tool into the connecting groove 17 and then use the tool to rotate the connector 8 to adjust the length of the connector 8 extending into the plug-in hole 15. This allows the mating length of the connector 8 with the plug-in hole 15 to be adjusted when the left lifting member 1 and the right lifting member 2 are clamping the necks of steel forgings of different diameters, improving the applicability and versatility of this lifting tool.

[0025] In one optional embodiment, the end of the connector 8 that passes through the connector hole 15 is provided with a pin hole 14, and the right lifting member 2 is provided with a positioning pin 12 that can cooperate with the pin hole 14. The positioning pin 12 is detachably installed on the right lifting member 2. In practical applications, after the connector 8 passes through the connector hole 15, the operator can also install the positioning pin 12 and insert it into the pin hole 14 of the connector 8, so that the positioning pin 12 can limit the end of the connector 8, which helps to further improve the stability of the connector 8 during hoisting and ensures that the left lifting member 1 and the right lifting member 2 can maintain stable clamping of the steel forging under the connection of the connector 8.

[0026] It should be noted that when the operator screws on the connector 8 and extends the connector 8 out of the connector hole 15, it is necessary to ensure that the pin hole 14 on the connector 8 is aligned with the positioning pin 12 so as to facilitate the subsequent assembly of the positioning pin 12.

[0027] In this embodiment, positioning rings 11 for installing positioning pins 12 are provided on the right lifting member 2 at positions above and below the plug-in member 8. For example, two positioning rings 11 are provided above and below the plug-in member 8, and each positioning ring 11 can be installed and fixed on the right lifting member 2 by means of welding, screw connection or other methods to achieve stable setting of the positioning ring 11 on the right lifting member 2.

[0028] In practical applications, by setting positioning rings 11 above and below the connector 8, when the operator installs the positioning pin 12, the positioning pin 12 can pass through the upper positioning ring 11, the pin hole 14 and the lower positioning ring 11 in sequence. This allows the positioning pin 12 to cooperate with the pin hole 14 of the connector 8 under the limitation of the two positioning rings 11, which helps to improve the positioning effect of the positioning pin 12 on the connector 8 and prevents the connector 8 from coming off during hoisting.

[0029] In one optional embodiment, a cushioning pad 7 is provided on the fitting portion 6. For example, the cushioning pad 7 is made of rubber and can be installed and fixed to the fitting portion 6 using adhesives, screws, etc. In practical applications, by providing the cushioning pad 7, direct contact between the fitting portion 6 and the surface of the steel forging can be avoided, allowing the cushioning pad 7 to provide good cushioning and protection, preventing the surface of the steel forging from being scratched by the lifting device.

[0030] In one optional embodiment, both the main lifting ring 9 and the auxiliary lifting ring 10 are connected to the vertical end 4 via a connecting plate 16. For example, one end of the connecting plate 16 can be welded to the corresponding main lifting ring 9 or auxiliary lifting ring 10, and the other end can be welded to the vertical end 4 of the left lifting member 1 or the right lifting member 2. By providing the connecting plate 16, the structural strength at the connection points between the main lifting ring 9 and the auxiliary lifting ring 10 and the corresponding vertical end 4 of the lifting member is improved.

[0031] In this embodiment, multiple connecting plates 16 can be provided on the left and right sides of the main lifting ring 9 or the auxiliary lifting ring 10. That is, the main lifting ring 9 and the auxiliary lifting ring 10 are connected to the vertical end 4 through multiple connecting plates 16. This can further improve the structural strength of the connection between the main lifting ring 9 and the auxiliary lifting ring 10 and the vertical end 4 of the corresponding lifting component.

[0032] The steel forging profile lifting tool described in this utility model is applicable to the lifting of steel forging profiles and has the advantages of simple structure, high positioning accuracy, and easy assembly and use.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
