Description

Technical Field

[0001] This utility model relates to the field of roller ring installation technology, and in particular to a roller ring installation tool for rolling mill roll boxes. Background Technology

[0002] With the rapid development of my country's iron and steel metallurgy industry, the high-speed bar rolling process has become increasingly mature, and its production efficiency has reached the world's advanced level. At present, the installation of roll rings in high-speed wire rod mill roll boxes is generally carried out manually. Due to the different installation positions of horizontal and vertical roll boxes, and the fact that the roll ring parts are made of YG20C and weigh about 95Kg, manual installation of roll rings is often time-consuming and labor-intensive, inconvenient to handle, and prone to slippage that could injure parts and personnel. Moreover, the installation accuracy is difficult to guarantee, affecting product use and consequently impacting market reputation.

[0003] Chinese Patent CN214828391U discloses a rolling mill roll box roll ring installation tool, which includes a roll sleeve. The roll sleeve has symmetrically fixed shafts at both ends, a base plate is fixed to one end of each shaft, and a fixing plate is fixed to the side of the base plate. This invention utilizes a designed fixing block and fixing cylinder. The fixing cylinder is directly fitted onto the outside of the bottom end of the lifting lug, while one end of the fixing block is inserted into a fixing groove to achieve a secure connection, preventing loosening due to rotation and improving the assembly stability of this invention. A designed compression spring applies elastic compression to the fixing block, ensuring a tighter fit and preventing detachment.

[0004] The aforementioned roller ring installation devices have significant limitations in practical applications. They can only perform hoisting operations on a single roller ring, resulting in extremely low work efficiency and greatly affecting the overall operation progress. Moreover, in scenarios requiring batch installation of roller rings, frequent single-ring hoisting operations not only increase labor and time costs but also bring many inconveniences, severely restricting the practicality of the device. Therefore, it is necessary to provide a rolling mill roll box roller ring installation tool to solve the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution for a rolling mill roll box roll ring installation tool: including a lifting arm 1, a lifting hole 2 is provided on the upper side of the lifting arm 1, a positioning post 3 is provided below the inner surface of the lifting arm 1, a through groove 4 is provided on the positioning post 3, a threaded rod 9 is rotatably installed inside the through groove 4, and an adjusting block 5 is sleeved on the outer wall of the threaded rod 9, and the adjusting block 5 is slidably installed on the through groove 4.

[0025] The top and bottom of the adjusting block 5 are provided with mounting grooves 10. A rotating shaft 14 is rotatably mounted inside the mounting groove 10. A locking block 6 is fixedly mounted on the rotating shaft 14. A first spring 13 is fixedly connected between the opposite surfaces of the two locking blocks 6 and the inner wall of the mounting groove 10. A locking block 12 is fixedly mounted on the inner wall of the mounting groove 10. A positioning groove 11 corresponding to the position of the locking block 12 is provided on the locking block 6.

[0026] The front end of the threaded rod 9 passes through the positioning post 3 and extends to the outside of the front end of the positioning post 3. A rotating plate 7 is fixedly installed at the front end of the threaded rod 9.

[0027] like Figure 4 As shown, the front end of the positioning column 3 is provided with several limiting grooves 17. The rotating plate 7 slides through the sliding holes opened on it to insert a limiting rod 18. The front end of the limiting rod 18 is fixedly installed with a handle 8, and the limiting rod 18 is engaged with the limiting groove 17. An annular baffle 16 is fixedly installed on the rear side of the outer wall of the limiting rod 18. A second spring 15 is sleeved on the outer wall of the limiting rod 18 between the annular baffle 16 and the rotating plate 7, so as to realize the self-locking of the rotating plate 7 and the threaded rod 9, enhance the stability of the adjusting block 5 in the designated position, and enable the locking block 6 to more reliably limit the roller ring on the outer wall of the positioning column 3.

[0028] like Figure 2 and Figure 3 As shown, the adjusting block 5 has a threaded hole that matches the threaded rod 9, and the adjusting block 5 is threadedly connected to the threaded rod 9 through the threaded hole. The position of the adjusting block 5 can be precisely adjusted by rotating the threaded rod 9, making the operation flexible and adaptable to different working needs.

[0029] like Figure 1 As shown, the rear end of the positioning column 3 is fixedly connected to the boom 1 by bolts, which makes installation and disassembly convenient and facilitates the replacement of positioning columns 3 of different specifications for use. The connection is also firm, ensuring safe use.

[0030] like Figure 3 As shown, the front of the locking block 6 is arc-shaped, which facilitates the quick installation of the roller ring on the outer wall of the positioning column 3.

[0031] like Figure 4 As shown, several equidistant and evenly distributed anti-slip rings are bonded to the outer wall of the handle 8, which can increase the friction between the hand and the handle 8, making it easier to pull the handle 8, and making the operation more effortless, stable and safe.

[0032] like Figure 3 As shown, the back of the locking block 6 is bonded with an anti-slip pad, which increases the friction between the locking block and the roller ring, making the locking more secure and effectively preventing the roller ring from shaking or slipping during hoisting, thus improving the safety of the installation tools.

[0033] The working principle of this utility model is as follows: All parts not mentioned in this device are the same as or can be implemented using existing technology. In use, the boom 1 is connected to a factory crane via the lifting hole 2, and the boom 1 is lowered to the designated position to lift the roller ring. The roller ring is fitted onto the outer wall of the positioning post 3. During this process, the roller ring contacts the inclined surface of the locking block 6, generating thrust, causing the locking block 6 to rotate around the rotating shaft 14 into the mounting groove 10 and stretch the first spring 13. After the roller ring passes the locking block 6, the locking block 6 resets under the elastic action of the first spring 13, thus allowing multiple roller rings to be placed on the outer wall of the positioning post 3 at once. After placement, the rotating plate 7 drives the threaded rod 9 to rotate. Through the threaded transmission and the sliding relationship between the adjusting block 5 and the through groove 4, the adjusting block 5 moves along the direction of the positioning post 3, driving the locking block 6 to move. This allows the right-angled surface of the locking block 6 to lock onto the outer surface of the outermost roller ring, achieving effective positioning. The cooperation between the locking block 12 and the positioning groove 11 ensures that the locking block 6 remains in a stable upright state, stably locking the roller ring. After hoisting to the installation position, adjust the adjusting block 5 away from the outermost roller ring, and press the locking block 6 to make it enter the installation groove 10 to remove the roller ring. This installation tool can hoist multiple roller rings at once, and can stably limit a specified number of roller rings by adjusting the position of the adjusting block 5 and locking the block 6 to prevent hoisting swaying, thus improving the flexibility, stability and practicality of use.

[0034] Before rotating the rotating plate 7, pull the handle 8 to adjust the position of the adjusting block 5. The movement of the handle 8 causes the limiting rod 18 to slide on the rotating plate 7. At the same time, the limiting rod 18 causes the annular baffle 16 to compress the second spring 15. As the limiting rod 18 moves, it disengages from the corresponding limiting groove 17. At this time, the rotating plate 7 can rotate freely because it loses the engagement between the limiting rod 18 and the limiting groove 17, thereby realizing the adjustment of the position of the adjusting block 5. After the position adjustment of the adjusting block 5 is completed, release the limiting of the handle 8. The second spring 15, by virtue of its elasticity, drives the limiting rod 18 to engage with the corresponding limiting groove 17 through the annular baffle 16, realizing the self-locking of the rotating plate 7 and the threaded rod 9. This enhances the stability of the adjusting block 5 in the designated position and allows the locking block 6 to more reliably limit the roller ring on the outer wall of the positioning column 3, improving the safety of the installation tool during use.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
