The utility model discloses can realize that 360 no dead angles of back-and-forth movement, oscilaltion and tray rotate, can quick alignment, shorten the change time, alleviate intensity of labour, improve the operating efficiency to greatly improved the factor of safety of operation.
Description
Technical Field
The utility model belongs to steel rolling machinery equipment field especially relates to a lower drunkenness cylinder change dolly.
Background
The operation side of each finishing mill in a hot rolling mill is provided with 2 lower roll shifting cylinders (seven rolling mills, totally 14 rolling mills), and when the lower roll shifting cylinders are replaced each time, due to the fact that no special replacing tool is provided, and the spherical seat of the lower roll shifting cylinders is heavy (20kg), the space where the disassembling operation is located is narrow and small, and the lower roll shifting cylinders are located near the edge, time and labor are wasted when the lower roll shifting cylinders are moved by manpower, the operation efficiency is very low, and certain safety risks are achieved.
Disclosure of Invention
The utility model aims at providing an operation convenient and fast shortens the change time, alleviates intensity of labour, improves the lower drunkenness roller jar change dolly of operating efficiency and factor of safety.
Therefore, the utility model discloses the technical solution who takes does:
a lower roller shifting cylinder replacing trolley comprises handrails, a frame, wheels, universal trays and a lifting mechanism; the rear end of the frame is provided with a handrail, wheels are arranged below the frame, and the front part of the frame is hinged with a lifting mechanism which consists of a rotating handle, a lifting screw rod, a screw nut, a telescopic rod, a fixing nut, a bolt and a supporting plate; two nuts pass through threaded connection on lifting screw, are equipped with fixation nut on one of them inboard lifting screw, and two upper and lower both ends of screw articulate a telescopic link respectively, and the articulated backup pad of telescopic link upper end passes through a bolt swing joint universal tray above the backup pad.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses convenient operation is swift, can realize that 360 no dead angles of back-and-forth movement, oscilaltion and tray rotate, can quick alignment, shortens the change time, alleviates intensity of labour, improves the operating efficiency to greatly improved the factor of safety of operation.
Drawings
FIG. 1 is a schematic view of a lower roll-shifting cylinder change carriage.
In the figure: the device comprises handrails 1, a frame 2, wheels 3, a lifting screw rod 4, a fixing nut 5, a universal tray 6, a supporting plate 7, a bolt 8, an expansion link 9, a rotating handle 10 and a nut 11.
Detailed Description
As shown in figure 1, the utility model discloses lower drunken roller jar change dolly, including handrail 1, frame 2, the universal tray 6 of wheel 3 and elevating system. The rear end of the frame 2 is provided with a handrail 1, four corners of the lower surface of the frame 2 are respectively provided with a wheel 3, and the front part of the frame 2 is provided with a lifting mechanism. The lifting mechanism consists of a lifting screw rod 4, a fixed nut 5, a supporting plate 7, a bolt 8, a telescopic rod 9, a rotating handle 10 and a screw nut 11. Two screw nuts 11 pass through threaded connection on elevating screw 4, are equipped with fixation nut 5 on the inboard elevating screw 4 of one of them screw nut 11, and two telescopic link 9 is articulated respectively at the upper and lower both ends of two screw nuts 11, and the articulated backup pad 7 of an upper end of telescopic link 9, the higher authority of backup pad 7 is through a rotatable universal tray 6 of 8 swing joint of bolt.
When the lower roll shifting cylinder is replaced, the replacing trolley is pushed to the operation position, the angle of the universal tray 6 is adjusted, the lifting screw rod 4 is rotated, and the universal tray 6 is lifted to the height of the base of the lower roll shifting cylinder; then the base bolt is disassembled, and the base is placed on the universal tray 6; the lifting screw rod 4 is rotated to lower the universal tray 6 until the base does not scrape the card equipment, and the replacing trolley is moved out of the operation position.
