Description

Technical Field

[0001] The utility model belongs to the technical field of special-shaped steel production, and in particular relates to a roller keyway position correction device. Background Art

[0002] During the production preparation process of special-shaped steel products, the rollers (usually key rollers) need to be removed and repaired after being used for a period of time, and then installed and used again after being repaired. The preparatory installation of the rollers takes up a lot of time, and its installation requires the cooperation of equipment such as cranes and roller loading trolleys. Since the key on the roller bearing seat that matches the roller keyway is located directly above it, the roller needs to be pulled and swung by the crane several times before each installation to adjust the keyway position so that the keyway is directly above the roller. This operation method of adjusting the position of the roller keyway using inertia has too high requirements for the operator. The time to adjust the roller keyway each time is long, and the distance between people and rollers is too close, which also poses a great safety hazard. Therefore, it is urgently necessary to provide a roller keyway position correction device to save the preparation time for roller installation, improve production efficiency, and reduce safety risks. Utility Model Content

[0003] In view of the deficiencies in the background technology, the utility model provides a roller keyway position correction device, which can quickly correct the position of the roller keyway, thereby saving preparation time for roller installation, effectively improving production efficiency and reducing safety risks.

[0004] To achieve the above purpose, the technical solution of the utility model is as follows:

[0005] A roller keyway position correction device, characterized in that it includes a sling and a sling ring, the sling is connected to the sling ring, one side of the sling ring is provided with a radially arranged positioning hole, the internal thread of the positioning hole is connected to a positioning rod, the end of the positioning rod close to the center of the sling ring extends to the inside of the sling ring, and the end of the positioning rod is connected to a positioning piece, the outer diameter of the positioning piece matches the roller keyway, and when the sling lifts the sling ring, the positioning hole is located at the upper end of the sling ring.

[0006] Preferably, the positioning member and the positioning rod are detachably connected.

[0007] Preferably, the positioning member and the positioning rod are connected by threaded connection.

[0008] Preferably, at least two adjusting rods are distributed on the lifting ring in a circular array, and each of the adjusting rods is arranged radially along the lifting ring and is threadedly connected to the lifting ring.

[0009] Preferably, one end of each adjusting rod close to the center of the lifting ring extends to the inner side of the lifting ring, and a locking piece is threadedly connected to the end thereof.

[0010] Preferably, the locking piece is made of rubber.

[0011] Preferably, the sling is connected to the lifting ring via two lifting ears, and the two lifting ears are symmetrically distributed on both sides of the positioning hole.

[0012] Preferably, each of the lifting ears and the lifting ring is assembled and connected by bolts.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] (1) The utility model uses the positioning piece to match the keyway of the roller, and connects the sling with the lifting equipment. Since the positioning piece is located at the upper end of the lifting ring, the roller can be quickly corrected during the process of being lifted by the lifting ring, so that the keyway is located directly above the roller, so as to facilitate the rapid installation of the roller, replacing the traditional correction method using inertial swing, saving the preparation time before installation, effectively improving production efficiency and reducing safety risks;

[0015] (2) The positioning rod, positioning member and lifting ring of the utility model are all detachably connected, and each component can be replaced according to actual conditions to meet the installation and use requirements of different rollers. At the same time, it is convenient for regular maintenance and servicing to extend its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figures 1 to 3 As shown, a roller keyway position correction device comprises a sling 1 and a lifting ring 2. The sling is connected to the lifting ring through two lifting ears 8. A radially arranged positioning hole 3 is provided on the upper side of the lifting ring. A positioning rod 4 is threadedly connected to the inner part of the positioning hole. One end of the positioning rod close to the center of the lifting ring extends to the inner side of the lifting ring, and a positioning piece 5 is connected to its end. The outer diameter of the positioning piece matches the roller keyway. The position of the positioning piece can be adjusted by screwing the positioning rod, and the positioning piece and the positioning rod are threadedly connected. The two can be freely disassembled and assembled. Because they are prone to wear due to long-term use, they are easy to replace and maintain. The two lifting ears are symmetrically distributed on both sides of the positioning hole. Each lifting ear is assembled and connected to the lifting ring with bolts 9. The bolts pass through the mounting holes 10 on the lifting ring to lock and fix the lifting ears, which is easy to install.

[0025] like Figure 1 and Figure 2 As shown, in order to ensure the safety of the roller during the lifting process, at least two adjusting rods 6 are distributed in a circular array on the lifting ring, each adjusting rod is arranged along the radial direction of the lifting ring and is threadedly connected to the adjusting hole 11 on the lifting ring for easy disassembly and assembly. One end of each adjusting rod close to the center of the lifting ring extends to the inside of the lifting ring, and a locking piece 7 is threadedly connected at its end. The roller can be clamped and fixed by screwing the adjusting rod to further enhance safety. The locking piece is made of rubber to avoid wear on the surface of the roller.

[0026] The method of using the utility model is as follows:

[0027] like Figures 1 to 3As shown, when in use, two products of the utility model are used together and are respectively sleeved on the two ends of the roller 12. The connection method of the two ends is the same, that is, first screw the positioning rod 4, insert the positioning member 5 into the keyway 13 of the roller 12, and then screw the adjusting rod 6 to lock and fix the roller 12, and then connect the sling 1 to the lifting equipment, and the lifting equipment will synchronously lift the lifting rings 2 at both ends of the roller 12. At this time, the roller 12 will realize automatic position correction under the action of the positioning member 5, so that the keyway 13 is adjusted to the uppermost position, thereby facilitating the subsequent roller installation.

[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
