Sleeve coupling with quick disassembly function

The present invention relates to a coupling, and more particularly to a sleeve coupling having a quick disassembly function.

Generally, steel mills are equipped with heating furnaces, and the hot steel billets in the heating furnace must be driven by the discharge furnace door, the excavator and the top discharger, and cooperate with each other to accurately control the hot steel. The embryo is taken out and placed on a roll table, and then transported to a rolling mill for rolling of the steel sheet.

Please refer to FIG. 1. FIG. 1 is a schematic view of a conventional furnace door mechanism group. In the above, the door mechanism group 5 of the discharge door includes the motor 50, the reduction gear set 51, the chain sprocket set 52, the cam switch 53, the coupling 54, and the brake set 55. The chain sprocket set 52 includes a transmission shaft 520 and a transmission sprocket 521 disposed on the transmission shaft 520, a first sprocket 522 and a second sprocket 523. The first sprocket 522 and the second sprocket 523 are connected to two positions of the oven door 525 by a chain 524, respectively.

Specifically, in the positioning control of the discharge furnace door 525, if it is not closed or opened too early, it will affect the temperature of the flat steel embryo in the furnace, resulting in abnormality of the rolling quality. The power for controlling the opening and closing of the furnace door 525 is derived from the motor 50. The motor 50 can be used to drive the reduction gear set 51 to drive the transmission shaft 520 of the chain sprocket set 52, thereby making the first sprocket 522 and the second sprocket 523 Rotating to drive the chain 524 to achieve the purpose of controlling the opening and closing of the furnace door 525. Wherein, the transmission shaft 520 and the cam switch 53 are coupled through the coupling 54. Therefore, the shaft 530 of the cam switch 53 cooperates with the synchronous rotation of the transmission shaft 520, and can be used as the position control of the detection furnace door 525, and the signal is reported Give a control system.

Please refer to FIG. 1 and FIG. 2 at the same time. FIG. 2 is an exploded view of the coupling of the furnace door mechanism group of FIG. When the field operator wants to perform the zeroing operation on the cam switch 53, The furnace door 525 is closed to a fixed point; then the screw 540 in the shaft housing at both ends of the coupling 54 is released by a tool (for example, a hexagonal wrench) (for example, a hexagon socket screw, but is not limited thereto); The shaft shells at both ends of the shaft 54 and the rubber block SPIDER 541 in the middle of the shaft shells are separated (as shown in FIG. 2); when the cam switch 53 detects inaccurate positioning, the reason is usually the positional shift of the cam switch 53. Therefore, the coupling 54 needs to be re-centered to ensure that the parallel, angular and axial deviations are within the allowable range, and the cam and the transmission shaft 520 can rotate in the same direction, and the shaft 530 of the cam switch 53 rotates synchronously with the transmission shaft 520 to The position of the furnace door 525 is correctly detected; after the coupling of the coupling 54 to the center, the cam switch 53 can be adjusted to zero. Therefore, it can be seen that the operator needs to completely remove (disassemble) the coupling 54 to perform the zeroing operation on the cam switch 53, which often causes waste of time.

In view of this, the present invention provides a telescopic coupling having a quick disassembly function.
