Embodiment Construction

[0018] The concrete steps of the method for preventing the passive shaft of the detached rack from falling off in the present invention are as follows:

[0019] 1. Make a protective frame

[0020] Depend on figure 1 It can be seen that the protective frame is composed of a baffle plate 1, a support plate 2 and a bolt 3. The size of the baffle plate 1 and the support plate 2 is designed according to the specific size of the groove 5 in the lower part of the frame 7. The baffle plate 1 is a rectangular plate with a length of 520mm, a width of 245mm, and a thickness of 26mm. Both ends of the baffle plate 1 are provided with bolt holes. The two support plates 2 are respectively vertically connected to the two ends of the baffle plate 1 through the bolts 3 , and at the same time, a protruding card platform 4 is respectively processed at the two ends of the two support plates 2 .

[0021] 2. Before installing the protective frame, first set the position on the convex edge 9 on bot...

Abstract

The invention provides a method for preventing an extracting mill frame driven shaft from shedding. A protective rack composed of a rectangular baffle plate, supporting plates with bosses and bolts is manufactured, and baffle blocks are respectively welded to raised edges at two sides of a groove at the lower part of the frame. In installation, a baffle plate of which one end is fixed to the supporting plate is put into the groove at the lower part of the frame, the other supporting plate is fixed to the other end of the baffle plate by bolts, the baffle plate and the supporting plates are orderly and transversely arranged in the groove of the frame from top to bottom, sides of the two supporting plates clings to inner walls at the two sides of the groove, the bottom surfaces of the supporting plates presses upon the upper surfaces of the raised edges at two sides of the groove, and the bosses of the supporting plates are blocked by the baffle blocks at the bosses. The method can effectively prevent an extracting roller mill frame driven shaft from shedding and being blocked by a water outlet of a memorial archway, thoroughly prevent a driven shaft shedding-caused production stopping accident, improve a unit yield, greatly reduce labor and resource waste and reduce treatment workload and labor intensity.

Description

technical field [0001] The invention belongs to the field of steel rolling machinery, and in particular relates to a method for preventing the passive shaft from falling off of a frame of a seamless steel pipe stripping machine Background technique [0002] The φ177mm hot-rolled seamless steel pipe stripping machine is an auxiliary equipment of the PQF continuous rolling mill. The roll frame of the stripping machine is composed of three sets of rolls, and the three rolls are closed to form a steel pipe rolling pass. There is a symmetrical groove in the lower part of the stripping roll frame, and there are symmetrical convex edges on both sides of the top of the groove. The front view of the groove is an equilateral triangle, its top angle is 120°, the length of the bottom side is 535mm, the width of the inner groove in the side view is 246mm, and the width of the convex edges on both sides is 33mm. [0003] Due to the large impact load that the roll frame of the tube remova...
