[0002] In the production process of steel cord, the spool is usually used as the winding structure of steel cord, and the spool is generally installed on the spool seat, in order to ensure the flexible rotation of the spool, the upper and lower two bearings in the spool seat need to be replaced frequently, such as Figure 1 As shown, the spool seat mainly comprises a shaft sleeve 4, two bearings 5 fixed detachably at the upper and lower ends in the shaft sleeve 4, a long shaft 6 erected in the shaft sleeve through the two bearings 5, a bottom plate 7 fixedly arranged at the bottom of the shaft sleeve 4, and a bottom plate 8 for placing the bottom plate 7. When the two bearings 5 are replaced, two symmetrical threaded holes 71 are generally formed on the bottom plate 7 of the spool seat 101, then two long screws 9 are used to push against the bottom plate 8 and slowly rotate until the shaft sleeve 4 of the spool seat 101 is lifted to a first height H relative to the long shaft 6, so that the inner rings of the two bearings 5 are separated from the bearing fixing end 61 of the long shaft 6, then the shaft sleeve 4 is separated from the long shaft 6, and the two bearings 5 are replaced.

[0003] However, such replacement method needs to ensure that the two long screws rotate synchronously to realize uniform stress on both sides, and such synchronous operation is relatively difficult, so the dismounting is relatively cumbersome, especially a production device usually has multiple spools, and when all the spool seats are dismounted and maintained in this way, it is time-consuming and laborious.

[0025] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present application provides a spooler seat disassembly tool 100, which comprises a cylinder sleeve 1, a top rod 2 and a handle 3.

[0026] The cylinder sleeve 1 comprises a cylinder wall 11, a cylinder top 12 and a convex ring 13, the side of the cylinder wall 11 is open, the inner side of the cylinder wall 11 comprises a semi-cylindrical surface 111 and two rectangular surfaces 112, the two rectangular surfaces 112 are symmetrically arranged in parallel and are tangentially arranged at two ends of the semi-cylindrical surface 111 respectively, the cylinder top 12 is arranged on the top of the cylinder wall 11, the convex ring 13 is arranged on the inner side of the cylinder wall 11 in a ring shape, the convex ring 13 is provided with a notch 131, and the tangent surfaces at two ends of the notch 131 are flush with each other, the notch 131 is arranged in the annular clamping groove 41 arranged on the top of the shaft sleeve 4 of the pulley seat 101, the first distance M is between the upper surface of the convex ring 13 and the lower surface of the cylinder top 12, the second distance N is between the upper surface of the annular clamping groove 41 arranged on the top of the shaft sleeve 4 and the top surface of the shaft sleeve 4, and the first distance M is greater than the second distance N. In this way, the cylinder sleeve 1 has sufficient height space for clamping.

[0027] The top rod 2 comprises a threaded rod 21 and a driving block 22, one end of the threaded rod 21 is fixedly connected to the bottom of the driving block 22, the other end of the threaded rod 21 vertically penetrates the cylinder top 12 along the first direction X, and the center line of the threaded rod 21 penetrates the center of the semi-circle of the semi-cylindrical surface 111, so that the long shaft 6 on the pulley seat 101 is prevented from moving up and down when the pulley seat 101 is disassembled, the threaded rod 21 is threadedly connected to the cylinder top 12, the difference between the first distance M and the second distance N plus the thickness S of the cylinder top 12 plus the first height H required for lifting the shaft sleeve 1 is less than the length L of the threaded rod 21, that is, L > M-N+S+H. In this way, the length of the threaded rod 21 is sufficient to make the inner rings of the two bearings 5 disengage from the bearing fixing end 61 of the long shaft 6.

[0028] The handle 3 is arranged on the other end of the top rod 2 along the second direction Y, and the first direction X is perpendicular to the second direction Y.

[0029] Optionally, the tangent surfaces at two ends of the notch 131 are flush with the side of the cylinder wall 11. The convex ring 13 does not exceed the side of the cylinder wall 11, so that damage is reduced, and the convex ring 13 is not hidden in the cylinder wall 11, so that the convex ring 13 is conveniently inserted into the annular clamping groove arranged on the pulley seat 101.

[0030] Optionally, the cylinder top 12 covers the cylinder wall 11. In this way, the center line of the threaded rod 21 can penetrate the center of the semi-circle of the semi-cylindrical surface 111.

[0031] Optionally, the cylinder sleeve 1 is an integrally processed and formed member. In this way, the integrally processing and forming can improve the overall strength and stability of the cylinder sleeve 1.

[0032] Optionally, the end of the other end of the threaded rod 21 is provided with a circular chamfer 211. Since the end of the other end of the threaded rod 21 is subjected to stress, the thread is prone to deformation and difficult to disassemble. In this way, the end is chamfered to facilitate disassembly and removal.

[0033] Optionally, the cross-sectional shape of the drive block 22 perpendicular to the first direction X is a regular hexagon. This facilitates the machining of the through hole for the handle 3 and the rotation of the push rod 2.

[0034] Optionally, the push rod 2 can be a one-piece machined component. This one-piece machining improves the overall strength of the push rod 2.

[0035] Optionally, the handle 3 can be detachably threaded through the other end of the top rod 2 along the second direction Y. This facilitates disassembly and maintenance.

[0036] Optionally, the cross-sectional shape of the handle 3 perpendicular to the second direction Y is circular. This facilitates machining using existing bolts, saving costs.

[0037] The principle of the I-beam wheel seat disassembly tool 100 of this utility model for disassembling the I-beam wheel seat 101 is as follows:

[0038] First, a ring groove 41 is pre-machined on the top of the bushing 4 of the existing I-beam wheel seat 101. During disassembly, first rotate the handle 3 in the reverse direction to rotate the drive block 22, so that the threaded rod 21 moves spirally upward relative to the cylinder top 12 to leave space until the convex ring 13 on the cylinder sleeve 1 can be inserted into the ring groove 41 of the I-beam wheel seat 101 from the side, and the ring groove 41 fits against the semi-cylindrical surface 111. Then rotate the handle 3 in the forward direction to rotate the drive block 22, so that the cylinder top 12 moves spirally upward relative to the threaded rod 21 until the other end of the threaded rod 21 abuts against the top of the long shaft 6 and does not move up or down. Then continue to rotate the handle 3 in the forward direction. As the cylinder sleeve 1 continues to move upward relative to the push rod 2, the convex ring 13 of the cylinder sleeve 1 carries the bushing 4 to move upward relative to the push rod 2 and the long shaft 6 to a first height H, so that the bearing 5 inside the bushing 4 is separated from the bearing fixing end 61 on the long shaft 6. Then lift the bushing 4 to separate it from the long shaft 6, and then replace the two bearings 5.

[0039] This utility model discloses a tool for disassembling I-beam wheel seats. It is easy to operate and can quickly disassemble the I-beam wheel seats, greatly improving production efficiency.

[0040] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
