Abstract
The utility model discloses a frame replacement dolly for short-stress-path vertical type rolling mills and belongs to the technical field of rolling mills. The frame replacement dolly comprises a bracket (1), a hydraulic cylinder (2), a frame replacement dolly (3), a frame replacement dolly track (4), a positioning pin (5) and an adjustable supporting bolt (6). The hydraulic cylinder (2) is arranged on the bracket (1). The frame replacement dolly (3) is connected with the hydraulic cylinder (2) through a hinge pin. The frame replacement dolly (3) is arranged on the frame replacement dolly track (4). The positioning pin (5) is arranged at the rear part of the frame replacement dolly (3). The adjustable supporting bolt (6) is arranged at the front part of the frame replacement dolly (3). According to the technical scheme of the utility model, by means of the frame replacement dolly, during replacement, the frame of a rolling mill can be supported more stably. Meanwhile, the frame of a horizontal rolling mill and the frame of a vertical type rolling mill can be interchanged completely.
Description
Technical field
The utility model belongs to the Mill Technology field, particularly relates to a kind of short-stress path vertical mill frame interchanging dolly.Can more steadily carry out smoothly the replacing of vertical mill frame, by changing connected mode and the Support Position of frame interchanging dolly and rolling-mill housing, revise the in the past defective of universal architecture, guarantee that simultaneously horizontal mill frame and vertical mill frame are in full accord.Be specially adapted to the frame interchanging of the two roller short-stress path vertical mills such as hot rolled rod, hot rolling wire and hot-rolled steel section.
Background technology
Short-stress path vertical mill frame interchanging dolly is used widely (such as Fig. 4) in the vertical machine row of short-stress path, but exists many defectives.Tradition frame interchanging dolly is screwed pin plate below the rolling-mill housing, and alignment pin is housed in the pin plate, and dolly is provided with pin-and-hole.Rolling-mill housing is fallen on the dolly together with pin plate when changing frame, locates by alignment pin.The shortcoming of this kind structure has two, and one, pin plate depart from the rolling-mill housing center of gravity in the Support Position of rolling-mill housing, causes milling train easily to lopsidedness (such as Fig. 4), when packing new rolling-mill housing into, because the inclination of milling train causes installation very difficult.Its two, the vertical mill frame need to be installed pin plate, and is different with the horizontal mill frame, causes fully Alternate of horizontal mill frame and vertical mill frame.
Summary of the invention
The purpose of this utility model is to provide a kind of short-stress path vertical mill frame interchanging dolly.When having solved traditional frame interchanging dolly and having carried out the vertical mill frame interchanging, the crank-sided shortcoming of rolling-mill housing.
The utility model comprises bearing 1, hydraulic cylinder 2, frame interchanging dolly 3, frame interchanging trolley track 4, alignment pin 5, adjustable supports bolt 6.Hydraulic cylinder 2 is installed on the bearing 1, frame interchanging dolly 3 is connected connection by bearing pin with hydraulic cylinder, frame interchanging dolly 3 is placed on the frame interchanging trolley track 4, alignment pin 5 is installed in the rear portion of frame interchanging dolly 3, corresponding rolling mill base bottom pin-and-hole 7, adjustable supports bolt 6 is installed in frame interchanging dolly 3 front portions, corresponding milling train intermediate support block 8.
Bearing 1 is welded steel structure.
Frame interchanging dolly 3 is provided with wheel, and the wheel of frame interchanging dolly 3 is placed on the frame interchanging trolley track 4, by locating about wheel rim.Under the driving of hydraulic cylinder 2, frame interchanging dolly 3 just can be done along frame interchanging trolley track 4 and seesaw to realize frame interchanging.When rolling-mill housing was changed, alignment pin 5 inserted in the bottom pin-and-hole 7 of rolling-mill housing, and adjustable supports bolt 6 is connected with the intermediate support block 8 of rolling-mill housing, can finely tune by adjustable supports bolt 6, to guarantee the plumbness of rolling-mill housing.Cancelled the pin plate 9 and the alignment pin 10 that are installed on the rolling-mill housing, made horizontal mill frame and vertical mill frame realize exchanging.
The utility model has the advantage of:
1, the design by this supporting construction, the strong point of the traditional vertical rolling-mill housing being changed dolly moves forward and backward, and supports more stablely when rolling-mill housing is changed, and has improved the in use crank-sided shortcoming of rolling-mill housing of traditional structure.
2, improved the frame interchanging situation of the two roller short-stress path vertical mills such as hot rolled rod, hot rolling wire and hot-rolled steel section.
