Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically a turning tool. Background Technology

[0002] Heavy industry involves numerous and diverse large steel structural components. If all lifting equipment could handle the weight of these large components, it would lead to waste in foundation construction. Large steel structures are rotated very infrequently; conventional rotations rely entirely on cranes, requiring double the pulling force of the crane winches for mid-air rotations. To meet the requirements for mid-air rotations, the configuration, maintenance, and cost of large lifting equipment will increase significantly.

[0003] The existing authorization announcement number CN 218168833 U3 discloses a mold steel processing device. The device's support frame is moved directly above the machine tool worktable, the fixture is aligned with the fixture mounting slot of the machine tool worktable, then the second tube body is pulled out of the first tube body, the fixture is clamped on the edge of the metal plate and fixed with screws, and then the second tube body is fixed with screws on the baffle. The hydraulic lifting rod is activated to raise the lifting block, and then the fixture is rotated through the bearing to flip the plate 180°.

[0004] However, using bearings to rotate large steel structures results in excessively high support points, large structural components, and high construction costs. Furthermore, the different segment designs and varying center of gravity heights make rotating the structure extremely dangerous, reducing its practicality.

[0005] Based on this, a flipping tool is now provided that can eliminate the drawbacks of existing devices. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-4 As shown, Figure 1 As shown, the flipping tool in this embodiment includes a crane body 1, with two hooks 2 slidably arranged on the top inner side of the crane body 1, and a wire rope arranged at the bottom of the hooks 2;

[0028] The bottom of the hook 2 is equipped with a flipper 3. Two clamping frames 4 are installed on the side where the two flippers 3 are connected by fixing bolts 9. A flipping base 5 is provided on the side where the two flippers 3 are separated. A mounting column 6 is fixedly installed at the center of the side of the flipping base 5 near the clamping frame 4. Positioning grooves are opened at the top and bottom of the mounting column 6 near the clamping frame 4. A mounting groove 7 that matches the mounting column 6 is opened on the side of the flipper 3 near the flipping base 5. A clamping component is provided inside the clamping frame 4. Positioning components are provided inside the flipper 3 and at the top and bottom of the mounting groove 7.

[0029] In this embodiment, during use, the tilting base 5 is inserted into the mounting groove 7 via the mounting column 6 and limited by the positioning component, thereby mounting the tilting base 5 on the surface of the tilter 3. It is then clamped to the left and right ends of the steel structure by the clamping component and fixedly connected to the tilter 3 by the fixing bolts 9. The tilter 3 is connected to the hook 2 at the bottom of the crane body 1 via a steel wire rope, thus lifting and tilting the steel structure. Under the action of the tilter 3, the ground provides support. Throughout the process, the force is always vertically downward. During the slow lifting process, the support force provided by the ground causes the tilter 3 to roll slowly. After rolling 180°, the large component has completed the tilting operation. The entire process is safe and reliable, and also prevents falls.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, the clamping frame 4 is equipped with a hanging arm 8 on the side away from the center of the flipper 3. The hook 2 is connected to the wire rope through the hanging arm 8 and is stably connected to the wire rope through the hanging arm 8.

[0031] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the flipper 3 has a threaded hole 10 on the side near the clamping frame 4 that matches the fixing bolt 9, so that the clamping frame 4 can be separated from the flipper 3 for easy carrying and storage.

[0032] In one embodiment, such as Figure 2 As shown, the clamping assembly includes an electric telescopic rod 11. Mounting holes are opened on the inner side of the clamping frame 4 near both the front and rear ends. The periphery of the electric telescopic rod 11 is fixedly connected to the inner wall of the mounting holes. The power output shaft of the electric telescopic rod 11 is fixedly mounted with a clamping plate 12. The two clamping frames 4 are installed on the top and bottom of one end of the steel structure. The electric telescopic rod 11 drives the clamping plate 12 to limit the steel structure. The clamping frame 12 is fixedly connected to the flipper 3 by fixing bolts 9.

[0033] In one embodiment, such as Figure 2 As shown, anti-slip grooves are provided on the side of the clamping plate 12 away from the electric telescopic rod 11 to increase the friction between the clamping plate 12 and the steel structure.

[0034] In one embodiment, such as Figure 3As shown, the positioning assembly includes two threaded rods 13. Each threaded rod 13 has a positioning block 14 fitted onto its surface, which is adapted to the positioning groove and threadedly connected to it. The end of the threaded rod 13 away from the positioning block 14 is rotatably connected to the inner wall of the flipper 3. The top and bottom of the flipper 3 are provided with grooves. An adjusting block 15 is rotatably provided inside the groove to drive the connected threaded rod 13 to rotate. By rotating the adjusting block 15 with a tool, the threaded rod 13 is driven to rotate, thereby causing the positioning block 14 to slide into the inside of the flipper 3 and disengage from the inner side of the positioning groove. This allows the flipping base 5 to be disassembled and replaced, preventing damage to the flipping base 5 after long-term operation and affecting the normal use of the device.

[0035] In one embodiment, such as Figure 3 As shown, the inside of the flipper 3 is provided with a lifting groove 16 for the positioning block 14 to slide up and down. The lifting groove 16 is connected to the mounting groove 7. By setting the lifting groove 16, the positioning block 14 can slide up and down stably.

[0036] In one embodiment, such as Figure 3 As shown, two slots 17 are provided on both sides of the positioning block 14 near the bottom. A card block 18 that matches the slot 17 is fixedly installed on the inner wall of the positioning slot. The card block 18 and the slot 17 cooperate with each other, so that when the flip base 5 is installed on the surface of the flipper 3, the connection is more stable and the force is even.

[0037] The above embodiments disclose a flipping tool, wherein when the device does not need to be flipped, two clamping frames 4 are installed on the top of the left and right ends of the steel structure, and the clamping plate 12 is driven by the electric telescopic rod 11 to limit the steel structure. The top hanging arm 8 is stably connected to the wire rope, thereby facilitating the crane body 1 to lift the steel structure.

[0038] When flipping is required, the flipping base 5 is inserted into the mounting groove 7 via the mounting column 6. By rotating the adjusting block 15 with a tool, the threaded rod 13 is rotated, causing the positioning block 14 to slide into the inside of the flipper 3 and insert into the positioning groove opened on the surface of the mounting column 6. Thus, the flipping base 5 is installed on the surface of the flipper 3. It is clamped to the top and bottom of one end of the steel structure by the clamping assembly and fixedly connected to the flipper 3 by the fixing bolts 9. The bottom hanging arm 8 is connected to the hook 2 set at the bottom of the crane body 1 by a steel wire rope, thereby lifting the steel structure. Under the action of the flipper 3, with the support of the ground, the flipper 3 slowly rolls during the slow lifting process. When it rolls 180°, the large component has completed the flipping operation, which can reduce the load on the crane body 1. The whole process is safe and reliable and can also prevent falling, greatly increasing the practicality and safety of the device.

[0039] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
