Abstract
Description
Technical Field
[0001] This utility model relates to the field of rolling mill technology, specifically a special tray for planetary rolling mill rolls. Background Technology
[0002] A planetary mill consists of one or two support rolls and many planetary rolls surrounding the support rolls. When the rolls are transferred inside the planetary mill, a special pallet is required for the transfer of the rolls.
[0003] When using a traditional dedicated pallet, workers place the rollers into the conical holes on the surface of the pallet, the size of which matches the size of the rollers. After placement, the rollers are transferred by moving the pallet with a forklift.
[0004] However, since the diameter of the conical holes on the surface of the special pallet is fixed, it can only be used to place rolls of the same diameter. If rolls of different diameters are to be transferred, the entire pallet needs to be replaced. As a result, companies have to purchase special pallets of various specifications, which increases the overall cost of transferring the rolls. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a special pallet for planetary rolling mill rolls. It solves the problem that the diameter of the conical hole on the surface of the special pallet is fixed, which means that only rolls of the same diameter can be placed. If rolls of different diameters are to be transferred, the company has to purchase special pallets of various specifications, which increases the overall cost of transferring rolls.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a special tray for planetary rolling mill rolls, comprising a body, a positioning groove on the surface of the body, a threaded hole on the inner wall of the body, the outer wall of the positioning groove communicating with the threaded hole, an annular body fitted to the inner wall of the body, a tapered hole on the surface of the annular body, a positioning block fixedly connected to the outer wall of the annular body, the outer wall of the positioning block being inserted into the outer wall of the positioning groove, a bolt threadedly connected to the inner wall of the positioning block, and the outer wall of the bolt threadedly connected to the inner wall of the threaded hole.
[0007] Preferably, the inner wall of the ring body is provided with a countersunk hole.
[0008] Preferably, a recessed platform is fixedly connected to the top of the body, a rubber pad is fixedly connected to the inner wall of the recessed platform, and a support is fixedly connected to the bottom of the body.
[0009] Preferably, a connecting ear is fixed to the bottom of the body, and a through hole is formed on the inner wall of the connecting ear.
[0010] Preferably, a reinforcing block is fixedly connected between the body and the connecting ear.
[0011] Preferably, the top of the body is provided with a groove and a through groove.
[0012] This utility model provides a special pallet for planetary rolling mill rolls. It offers the following advantages: This special pallet for planetary rolling mill rolls, through the cooperation of a ring body, positioning block, positioning groove, bolts, threaded holes, and countersunk holes, enables the transfer of rolls of different diameters by replacing the internal ring body parts. This solves the problem that the diameter of the tapered hole on the surface of the special pallet is fixed, which limits the placement of rolls of the same diameter. Furthermore, transferring rolls of different diameters would require companies to purchase multiple specifications of special pallets, increasing the overall cost of roll transfer.
[0013] By combining the recessed platform, support column, and rubber pad, the storage area of the pallet body is reduced when it is not in use. This solves the problem that traditional pallets, due to the lack of a reasonable stacking design, can usually only be laid flat when not in use, occupying a lot of ground space and thus increasing the storage area of the dedicated pallet.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] The diameter of the tapered holes on the surface of the special pallet is fixed, which means that only rolls of the same diameter can be placed. If rolls of different diameters are to be transferred, the company has to purchase special pallets of various specifications, which increases the overall cost of transferring the rolls.
[0022] In view of this, the present invention provides a special pallet for planetary rolling mill rolls. Through the cooperation between the ring body, positioning block, positioning groove, bolt, threaded hole and countersunk hole, rolls of different diameters can be transferred by replacing the internal ring body parts. This solves the problem that the diameter of the conical hole on the surface of the special pallet is fixed, which means that only rolls of the same diameter can be placed. If rolls of different diameters are to be transferred, the enterprise has to purchase special pallets of various specifications, which increases the overall cost of transferring rolls.
[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.
[0024] Example 1, by Figure 1-5 As can be seen, a special pallet for planetary rolling mill rolls in this case includes a body 1, a positioning groove 12 is provided on the surface of the body 1, a threaded hole 14 is provided on the inner wall of the body 1, the outer wall of the positioning groove 12 is connected to the threaded hole 14, an annulus 10 is attached to the inner wall of the body 1, a tapered hole 16 is provided on the surface of the annulus 10, a positioning block 11 is fixedly connected to the outer wall of the annulus 10, the outer wall of the positioning block 11 is inserted into the outer wall of the positioning groove 12, a bolt 13 is threadedly connected to the inner wall of the positioning block 11, and the outer wall of the bolt 13 is threadedly connected to the inner wall of the threaded hole 14.
[0025] In the specific implementation process, it is worth noting that when transferring the rolls, the operator places the rolls in the conical hole 16 and then transfers the rolls. If the rolls of different diameters are to be transferred, the operator first uses a tool to rotate the bolt 13, rotating the bolt 13 out of the threaded hole 14 and the positioning block 11 in sequence. The operator removes the bolt 13, and then removes the ring 10. The operator places the replacement ring 10 in the recessed hole on the surface of the body 1. At this time, the ring 10 drives the positioning block 11 on the surface to move, inserting the positioning block 11 into the positioning groove 12. After that, the operator rotates the bolt 13 again, rotating the bolt 13 into the positioning block 11 and the threaded hole 14 in sequence, and fixing the replacement ring 10 onto the body 1. The size of the conical hole 16 on the surface of the ring 10 matches the size of the roll to be transferred, so that the rolls of different diameters can be transferred by replacing the ring 10 parts inside the body 1.
[0026] Furthermore, a countersunk hole 15 is provided on the inner wall of the ring body 10;
[0027] In the specific implementation process, it is worth noting that when the staff fixes the replaced ring 10, the head of the bolt 13 is rotated into the inside of the countersunk hole 15 to hide the head of the bolt 13, so as to avoid the head of the bolt 13 protruding and affecting the placement and use of the roll.
[0028] Furthermore, a recessed platform 7 is fixedly connected to the top of the main body 1, a rubber pad 9 is fixedly connected to the inner wall of the recessed platform 7, and a support column 8 is fixedly connected to the bottom of the main body 1.
[0029] In the specific implementation process, it is worth noting that the rubber pad 9 is made of wear-resistant, non-slip, and elastic rubber material, such as nitrile rubber. When storing multiple idle bodies 1, the staff moves one body 1, thereby moving the corresponding support column 8 and inserting the support column 8 into the recess 7 on the surface of another body 1. At this time, the outer wall of the support column 8 contacts the rubber pad 9. The rubber pad 9 increases the friction between the recess 7 and the support column 8, improving the stability between the two adjacent bodies 1. Finally, multiple idle bodies 1 are stacked together, thereby reducing the storage area of the bodies 1 when idle.
[0030] Example 2, by Figure 1-3 It can be seen that a connecting ear 4 is fixedly connected to the bottom of the main body 1, and a through hole 5 is opened on the inner wall of the connecting ear 4;
[0031] In the specific implementation process, it is worth noting that when the roll is transferred, the workers insert the forks on both sides of the forklift into the through holes 5 inside the connecting ears 4 on both sides in turn. After that, the forklift moves the body 1 through the connecting ears 4, thereby moving the roll and realizing the transfer operation of the roll.
[0032] Furthermore, a reinforcing block 6 is fixedly connected between the main body 1 and the connecting ear 4;
[0033] In the specific implementation process, it is worth noting that the reinforcing block 6 has a triangular structure and is welded between the body 1 and the connecting ear 4. It plays a role in enhancing the strength of the connection part and preventing the connecting ear 4 from separating from the body 1 when subjected to large external forces. Thus, the reinforcing block 6 enhances the connection strength between the connecting ear 4 and the body 1 and can withstand large external forces.
[0034] Furthermore, the top of the main body 1 is provided with a groove 2 and a through groove 3 respectively;
[0035] In the specific implementation process, it is worth noting that the groove 2 and the through groove 3 reduce the weight of the body 1. After the weight of the body 1 is reduced, the overall weight of the body 1 is reduced. During the transfer process, the load on the transfer equipment such as forklifts is reduced, which can improve the transfer speed and shorten the transfer time.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
