Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically to a special hoisting tool for supporting roller bearing seats. Background Technology

[0002] The cold-rolled support roll bearing housing and the assembled support roll are generally moved by hoisting. Since the support roll (with bearing housing) weighs about 40 tons, the traditional method uses a lifting lug insertion structure. The lifting lug is inserted into the inner hole of the bearing for hoisting. There is no anti-loosening structure between the lifting lug and the inner hole of the bearing housing. It must be kept stable during hoisting. However, since the outer circular surface of the lifting lug and the inner circular surface of the bearing housing are both circular, there is a risk of them falling off during hoisting, resulting in a high risk factor for hoisting.

[0003] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Summary of the Invention

Detailed Implementation

[0014] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings. Example

[0015] like Figures 1 to 4 As shown, Figure 1 This is a three-dimensional structural diagram of the special lifting tool for the support roller bearing seat; Figure 2 This is a structural cross-sectional view of the special lifting tool for the support roller bearing housing; Figure 3 This is a structural side view of the special lifting tool for the support roller bearing housing; Figure 4This is a schematic diagram showing the use of a special lifting tool for the support roller bearing housing.

[0016] The special lifting tool for the support roller bearing seat of this utility model can be detachably connected to the inner hole of the support roller bearing seat 6. The inner hole includes a threaded section and a connecting section arranged coaxially. Existing lifting lugs are all connected by directly inserting into the connecting section.

[0017] The special lifting tool for the support roller bearing seat includes a connecting rod 1, a plug-in rod 2, and a connecting plate 3. The plug-in rod 2 is inserted into the plug-in section, and a connecting hole 21 is provided through the axis of the plug-in rod 2. The connecting rod 1 is disposed in the connecting hole 21. A first limiting member 4 and a second limiting member are respectively provided at both ends of the connecting hole 21. The first limiting member 4 and the second limiting member are connected to the connecting rod 1, thereby stabilizing the relative position of the connecting rod 1 and the plug-in rod 2. A connector 11 is provided at one end of the connecting rod 1, and the connector 11 is threadedly connected to the threaded section. The connecting plate 3 is fixedly disposed on the plug-in rod 2, and a lifting hole 31 is provided on the connecting plate 3. The lifting hook is connected to the lifting hole 31 through a lifting cable 7.

[0018] Preferably, the connecting rod 1 and the plug rod 2 are coaxially arranged.

[0019] Preferably, the cross-sectional diameter of the connector 11 is larger than the cross-sectional diameter of the connector hole 21, thereby enabling the limiting of one end of the plug rod 2.

[0020] Specifically, the first limiting member 4 is set as a limiting ring, which is sleeved on the connecting rod 1 and positioned between the connecting head 11 and the plug rod 2. The inner diameter of the limiting ring is smaller than the cross-sectional diameter of the connecting head 11, thereby limiting the position of the limiting ring through the connecting head 11 and the plug rod 2. By setting the limiting ring, the relative position of the plug rod 2 and one side of the connecting rod 1 can be effectively limited.

[0021] The second limiting member is set as a limiting pin. The end of the connecting rod 1 away from the connecting head 11 is provided with a locking hole 12. The locking hole 12 is radially through. The limiting pin is inserted into the locking hole 12, thereby limiting the relative position of the plug rod 2 and one side of the connecting rod 1. The limiting pin can be a cotter pin. The inserted cotter pin bends the open end to fix the limiting pin in the locking hole 12.

[0022] Preferably, the connecting plate 3 is a straight plate, and the lifting hole 31 and the plug rod 2 are respectively located at both ends of the connecting plate 3, so as to ensure that the plug rod 2 naturally hangs below the lifting hole 31 during lifting, thereby ensuring the stability of the overall center of gravity.

[0023] Meanwhile, the connecting rod 1 can rotate relative to the plug rod 2, which facilitates the self-adjustment of the center of gravity of the support roller bearing seat 6 during hoisting, ensuring that the center of gravity is on the same vertical line as the sling 7.

[0024] The connecting plate 3 is provided with a handle 5, which is fixedly located on the side of the connecting plate 3 away from the connector 11. The handle 5 makes it easier to grasp the plug rod 2 so as to simultaneously insert the connecting rod 1 into the connecting hole 21 and the plug rod 2 into the inner hole.

[0025] The plug-in rod 2 includes an insertion section and a connecting section. The insertion section and the connecting section are coaxially arranged cylindrical sections. The insertion section is inserted into the connecting section. The cross-sectional diameter of the insertion section is smaller than that of the connecting section, thereby forming a limiting boss on the plug-in rod 2 to limit the length of the plug-in rod 2 inserted into the connecting section. The connecting plate 3 is provided with a fixing hole. The connecting section is disposed in the fixing hole and welded to the connecting plate 3. The larger cross-sectional diameter of the connecting section facilitates the increase of the welding length and ensures the connection strength.

[0026] This utility model provides a connecting rod 1 that is connected to the plug rod 2, enabling a stable threaded connection between the connecting rod 1 and the inner hole. Simultaneously, the insertion of the plug rod 2 into the inner hole enhances the connection strength and stability between the lifting device and the support roller bearing seat 6, thereby ensuring the safety of the lifting operation.

[0027] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
