Description

Technical Field

[0001] This invention relates to the field of installation technology for rotary guide seats at the inlet and outlet of rolling mills, and in particular to a method for quick installation of clamping blocks for rotary guide seats. Background Technology

[0002] In the process design and layout of high-speed wire rod production lines, the roughing mill area often features alternating horizontal and vertical short-stress mills. To meet production demands, roll changes are required in the roughing mill. During roll changes, due to the large size and weight of the vertical frame of the roughing mill, the guides and the mill are designed separately. The inlet and outlet guides are installed on rotating guide seats on both sides of the mill, and their position changes are driven by the rotation of the guide seat's support shaft. When the dovetail at the front of the rotating guide seat is fully in contact with the dovetail at the front of the support seat, clamping blocks are used to secure the rotating guide seat and the rear dovetail of the support seat, and T-bolts and nuts are used to fix the clamping blocks. At this point, the guide installation is complete. The reverse process is the disassembly process.

[0003] Disassembly and installation require one worker to lift a universally designed slotted clamping block weighing up to 20 kilograms, while another worker needs to continuously tighten the nuts, making it a labor-intensive process.

[0004] To address the problem of inconvenient installation of the original clamping block, this application proposes a quick installation method for the rotating guide seat clamping block. Summary of the Invention

[0005] To address the aforementioned technical problems and overcome the shortcomings of existing technologies, this invention provides a quick installation method for a rotating guide seat clamping block. By utilizing the design of a fishhook-shaped rotating handle on the top of the clamping block device, the installation of the clamping block device is facilitated, solving the problem of inconvenient installation of the original clamping block.

[0006] The quick installation method for the rotating guide seat clamping block provided in this solution includes the following steps: Hang the hook-shaped rotating handle of this device on the upper rotating guide seat, so that the upper and lower dovetail parts of this device are connected to the dovetail parts of the rotating guide seat and the lower rotating guide support, respectively. That is, the upper and lower dovetail parts of this device are embedded in the dovetail parts of the rotating guide seat and the rotating guide support. Use T-bolts and fixing nuts to fix this device on the rotating guide seat or the rotating guide support.

[0007] Furthermore, the device includes a body with a through groove, a removable thickened pad is detachably connected to the outside of the body, and the removable thickened pad has a groove with an overlapping area with the through groove; at least one fishhook-shaped rotating handle is connected to the body, the fishhook-shaped rotating handle has a hook-like structure to hang the body on other objects.

[0008] Furthermore, there are two fishhook-shaped rotating handles, which are symmetrically connected to the top of the body.

[0009] Furthermore, the fishhook-shaped rotating handle is rotatably connected to the main body via a rotating hinge.

[0010] Furthermore, the removable thickened gasket is detachably connected to the body via two fixing bolts.

[0011] Furthermore, the slotted cross-section of the removable thickened gasket is adapted to the through-slot cross-section of the body.

[0012] Furthermore, the detachable thickened gasket is a rectangular plate-like structure with a groove set in the middle.

[0013] Furthermore, the cross-section of the through groove of the body is rectangular or circular.

[0014] The beneficial effects of this invention are: The quick installation method for the rotating guide seat clamping block provided by this invention features a removable thickened gasket at the edge of the through groove, enabling convenient replacement of the contact area between the clamping block device and the fixing component, extending the replacement cycle of the clamping block device, and reducing maintenance costs. In addition, the design of the fishhook-shaped rotating handle on the top of the clamping block device facilitates the installation of the clamping block device, solving the problems of inconvenient installation of the original clamping block and easy damage to the edge of the through groove for installing the clamping block.

Detailed Implementation

[0016] The quick installation method of the rotating guide seat clamping block of the present invention includes the following steps: Hang the hook-shaped rotating handle 401 of this device 301 on the upper rotating guide seat 104, so that the upper and lower dovetail parts of this device 301 are connected to the dovetail parts of the rotating guide seat 104 and the lower rotating guide support 103 respectively. Use T-bolts and fixing nuts 102 to fix this device 301 on the rotating guide seat 104 or the rotating guide support 103.

[0017] like Figure 1 As shown in the diagram, before the improvement, the rotating guide seat 104 of the roughing mill in the high-speed wire rod production line uses a fastening nut 102 to lock the clamping block 101 into the dovetail portion of the rotating guide support 103, thus fixing it in place. During operation, one person needs to lift the handle of the clamping block 101 while another person tightens the fastening nut 102 to connect it to the T-bolt passing through the mounting groove of the clamping block 101, which is time-consuming and labor-intensive.

[0018] like Figure 2 As shown, the original clamping block 101 is welded together from the body 202 and the handle 201. The body 202 has an installation slot 203. The edge 204 of the installation slot is deformed due to long-term contact with the fixing nut 102. In severe cases, the clamping block 101 will become unusable and needs to be replaced.

[0019] like Figure 3 The diagram shows the installation effect of the improved device 301. A fixed ring 302 is welded to the upper side of the rotating guide seat 104 and tilted at a certain angle. During use, because the fixed ring 302 is tilted at a certain angle, this design allows the hook-shaped rotating handle 401 to be more accurately aligned with the welded fixed ring 302. Utilizing gravity, the device 301 is suspended inside the fixed ring 302 by the hook-shaped rotating handle 401, and the upper and lower dovetail portions of the main body 202 are precisely connected to the dovetails at the rear ends of the rotating guide seat 104 and the rotating guide support 103. At this time, the clamping blocks are relatively close together, and the threaded portion of the T-bolt is automatically exposed, allowing only one person to tighten the fixing nut 102. While tightening the nut, the gap between the removable thickened washer 404, the device 301, and the guide seat is gradually eliminated until they are completely fitted. Compared to the old model, the new gasket is larger and thicker, making it more stable. In addition, the detachable design of the 403 fixing bolts allows for individual replacement of the gasket if it is damaged, greatly saving time and manpower.

[0020] like Figure 4 The diagram shows the specific structure of the improved device 301, namely the rotary guide seat clamping block device provided in this application that facilitates quick installation.

[0021] This device 301 consists of a main body 202, a hook-shaped rotating handle 401, a rotating hinge 402, a fixing bolt 403, and a removable thickened washer 404. The rotating hinge 402 is connected to the main body 202, and the hook-shaped rotating handle 401 is mounted on the rotatable shaft of the rotating hinge 402. To maintain balance, this assembly uses two sets of hook-shaped rotating handles 401 and rotating hinges 402, symmetrically connected on the left and right sides of the upper surface of the main body 202. The removable thickened washer 404 is mounted on the main body 202 by the fixing bolt 403. In use, the operator firmly grasps the hook-shaped rotating handle 401 with both hands to hook it onto the fixing ring 302, and then tightens the nut, saving time and effort; the removable thickened washer 404, with its grooved edges deformed under pressure, can be quickly replaced, thus saving on spare parts consumption. During operation, only one operator needs to lift the device 301 and insert the hook-shaped structure at the head of the fishhook-type rotating handle 401 into the fixing ring 302 of the rotating guide seat 104. At this time, the threaded part of the T-bolt will naturally extend, and the operator can tighten the nut without the assistance of other personnel.

[0022] The improved rotating guide seat clamping block device allows for timely replacement of the removable thickened gasket 404 when it deforms during use, ensuring the rotating guide seat 104 is securely installed and saving on spare parts consumption caused by frequent replacement of the main body 202.

[0023] In addition to the embodiments described above, the present invention may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
