Description

Change the device of rolling mill pressing cylinder
Technical field
The utility model relates to a kind of device changing rolling mill pressing cylinder.
Background technology
As shown in Figure 1, hot rolling mill depress oil cylinder 3 totally two, be arranged on the below of memorial archway 1 entablature, be connected with revolution plat shaft bearing, oil cylinder 3 piston rod head is designed with a boss 4, it is just to top backing up roll bearing block, and the boss 4 of oil cylinder 3 is aimed at the downward swaging of top chock upper groove and become roll-force, and groove plays the role of positioning.Being designed with a tie-beam 2 between two oil cylinders makes two oil cylinders 3 can be servo-actuated along with roller system.Oil cylinder 3 is each heavy 15 tons, and be located at the below of the entablature of mill housing due to oil cylinder 3, the suspension hook of crane is blocked by crossbeam, so its installation and removal are very difficult.
Summary of the invention
The new object of this practicality is the device providing a kind of simple load and unload replacing rolling mill pressing cylinder.
The technical scheme solved the problems of the technologies described above is as follows:
Change the device of rolling mill pressing cylinder, comprise base, also comprise the lifting frame be arranged on base, lifting frame comprises upper beam, underbeam and the arm support between upper beam and underbeam, arm support is made up of first connecting rod and second connecting rod, one end of first connecting rod and the lower surface of upper beam hinged, the other end of first connecting rod is slidably fitted on the guide rail set by underbeam upper surface, one end of second connecting rod and the upper surface of underbeam hinged, the other end of second connecting rod is slidably fitted on the guide rail set by upper beam lower surface.
Described base comprises crossbeam, the first column, the second column, and the two ends of crossbeam are connected with the first column and the second column respectively.
The bottom of described first column and the second column is equipped with roller.
Described first connecting rod and second connecting rod are equipped with roller, and first connecting rod is coordinated with the slide on underbeam by roller, and second connecting rod is coordinated with the slide on upper beam by roller.
The upper surface of described upper beam is provided with groove.
This device also comprises jack, and one end of jack is connected with underbeam, and one end of jack is connected with upper beam.
Have employed such scheme, during work, this device is pushed milling train inside from milling train track, rise arm support by jack, the groove on upper beam is aimed at the boss of two oil cylinders, then oil cylinder and tie-beam are together pulled down, oil cylinder entirety is made to fall into upper beam, arm support is fallen, after together release outside milling train by the oil cylinder dropped on arm support and in company with this device, carry out next step the work to oil cylinder.The step of oil cylinder is installed on the contrary.
The utility model has the advantage of: cross frame makes elevating mechanism structure simple; Adopt jack lifting dismounting oil cylinder, mechanism is simple and reliable; Transportable steel structure base, work is convenient.
Accompanying drawing explanation
Fig. 1 is the assembling schematic diagram of hot rolling mill depress oil cylinder and memorial archway;
Fig. 2 is the structural representation of the device of replacing rolling mill pressing cylinder of the present utility model;
Fig. 3 is the schematic diagram of arm support;
1 is crossbeam, and 2 is the first column, and 3 is the second column, and 4 is roller, and 5 is upper beam, and 6 is underbeam, and 5a is groove, and 7 is first connecting rod, and 8 is second connecting rod, and 9 is jack.
Detailed description of the invention
As shown in Figures 2 and 3, change the device of rolling mill pressing cylinder, comprise base, be arranged on the lifting frame on base and the jack be arranged on lifting frame formed,
Base comprises crossbeam 1, first column 2, second column 3, and the two ends of crossbeam 1 are connected with the first column 2 and the second column 3 respectively.After the bottom of the first column 2 and the second column 3 is equipped with roller 4, walking can be promoted, base is made to form a dolly that can walk, spacing between two rollers 4 equals the changing track for roll width in mill housing, base overall width is less than the width of roller system of rolling mill, and roller 4 is forging process parts.
Lifting frame comprises upper beam 5, underbeam 6 and the arm support between upper beam 5 and underbeam 6, arm support is made up of first connecting rod 7 and second connecting rod 8, first connecting rod 7 and second connecting rod 8 hinged at middle part, one end of first connecting rod 7 and the lower surface of upper beam 5 hinged, the other end of first connecting rod 7 is slidably fitted on the guide rail set by underbeam 6 upper surface, one end of second connecting rod 8 and the upper surface of underbeam hinged, the other end of second connecting rod 8 is slidably fitted on the guide rail set by upper beam 5 lower surface.First connecting rod 7 and second connecting rod 8 are equipped with roller, and first connecting rod 7 is coordinated with the slide on underbeam 6 by roller, and second connecting rod 8 is coordinated with the slide on upper beam 5 by roller.The upper surface of described upper beam 5 is provided with groove 5a, and this groove 5a is for installing the boss of oil cylinder.
One end of jack 9 is connected with underbeam 5, and one end of jack 9 is connected with upper beam 6, at least includes two jack 9 in the present embodiment.
During work, this device is pushed milling train inside from milling train track, arm support is risen by jack 9, groove 5a on upper beam 5 is aimed at the boss of two oil cylinders, then oil cylinder and tie-beam are together pulled down, make oil cylinder entirety fall into upper beam 5, arm support is fallen, after together release outside milling train by the oil cylinder dropped on arm support and in company with this device, carry out next step the work to oil cylinder.The step of oil cylinder is installed on the contrary.
