Embodiment Construction

[0023] The invention provides a device capable of quickly replacing the steering sheave. The device uses the principle of screw transmission to convert rotary motion into linear motion. The mechanism runs smoothly and can transmit large axial force. It also has a self-locking function. The size of the device can be determined according to the size of the space where the steering sheave is located.

[0024] see Figure 1 to Figure 10 , the present invention mainly includes a base 1, a sleeve 2, a lifting shaft 3, a rotating nut 4, a pull rod 5, a claw bracket 6, a claw 7, a pin 8, a torsion bar 9, and a thrust ball bearing 11. Wherein, three holes with a diameter of 17mm are evenly distributed on the base 1, which can be fixed on the axle 14 of the steering sheave 13 through M16 bolt connection. The upper surface of the base 1 is welded with four clamping platforms 16 distributed along the circumferential direction for limiting the rotation of the sleeve 2 . The lower end of...

Abstract

The invention discloses a replacement device of a horizontal type looping car steering rope sheave. The replacement device comprises a sleeve, a lifting shaft, a rotary nut and a plurality of pull rods arranged around the sleeve; the sleeve is vertically installed on a sheave shaft of the steering rope sheave through a base, axial sliding grooves corresponding to the pull rods are formed in the cylinder wall of the sleeve, the lower end of the lifting shaft is positioned in the sleeve and is provided with lug seats corresponding to the sliding grooves, one end of each pull rod is hinged to the lug seat in the corresponding sliding groove, and the other end of each pull rod is provided with a pull claw corresponding to a process hole in the steering rope sheave; and a rotary nut is installed at the upper end of the sleeve through a thrust ball bearing and is matched with the lifting shaft through threads, and a torsion bar is arranged on one side of the rotary nut. According to the replacement device, the multiple pull rods are used for safely and stably drawing out the steering rope sheave from the sheave shaft through the power provided by the rotary nut. The replacement device well solves the problem of disassembly of the looping steering rope sheave, improves the replacement efficiency of the steering rope sheave, guarantees the smooth production, and lowers the labor intensity of workers.

Description

technical field [0001] The invention relates to a device capable of quickly replacing the steering sheave of a horizontal looper during the maintenance process of a cold-rolling and acid-rolling unit, and belongs to the technical field of workshop tools. Background technique [0002] The looper is a device used to store strip steel and ensure the continuous and stable operation of the pickling line in the cold rolling plant. The looper is pulled by the wire rope to move back and forth. During the traction process, the wire rope needs to pass through the steering rope on the looper The wheel changes direction. In actual production and application, abnormal noise of the steering sheave bearing and damage to the cage often occur, and it is necessary to stop immediately to replace the steering sheave. However, the space where the looper is located is narrow and there is no suitable lifting point. Moreover, the diameter and weight of the steering sheave are relatively large. Al...
