Description
Technical field
The utility model relates to metallurgical machinery equipment service technique field, particularly relates to a kind of specific purpose tool of online dismounting mill balancing block.
Background technology
Mill balancing block assembly is heavy and medium plate mill important composition parts, heavy and medium plate mill is generally made up of (as shown in Figure 1, Figure 2) four balance weights 3, be installed on the both sides, front and back of mill housing 5 respectively, primary responsibility balance milling train each several part power, ensures normally carrying out of rolling.Be made up of control valve group, system pipeline and compensating cylinder, the quality of its working condition directly affects the normal production of milling train.
Because balance weight 3 is fixed in mill housing 5, then the upper backup roll 1 of milling train must be removed owing to limiting by rack construction of the rolling mill when changing balance weight 3, by chain block, balance weight 3 is hung memorial archway 5, be placed on lower backing roll 2, then utilize working roll push-and-pull cylinder 6 that backing roll is pulled away from memorial archway 5, carry out replacing balance weight 3, after balance weight 3 is changed, finally return again and load onto lower backing roll.Whole examine and replace process at least needs more than 48 hours.Repair time is long, and personnel labor intensity is large, a general overhaul technical barrier of Shi Ge cut deal enterprise mill balancing block replacing all the time.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of specific purpose tool of online dismounting mill balancing block of effective raising overhaul efficiency.
For solving the problem, the specific purpose tool of a kind of online dismounting mill balancing block described in the utility model, is characterized in that: this instrument comprises guide blot, base and is located at the adjustment screw on described base, slide block with holes, hydraulic cylinder; The side of described base is provided with hook; The cylinder rod end of described hydraulic cylinder is connected with described slide block.
The cylinder body end of described hydraulic cylinder is connected with described base by bolt.
The cylinder rod end of described hydraulic cylinder is connected with described slide block by bearing pin.
Described adjustment bolt is connected with described base by screw thread.
Gib head on described hook and working roll push-and-pull cylinder matches.
The utility model compared with prior art has the following advantages:
1, owing to being provided with the adjustment bolt of adjustment height in the utility model, therefore, the devices such as rolling mill can be dismantled, the gap between slide block and balance weight base is utilized to adjust, conveniently at narrow and small working space, direct effortlessly can carry out dismounting operation to balance weight, not only effectively improve operating efficiency, and safe and reliable, and reduce labor intensity.
2, the utility model completes replacing operation overall process and only needs 6 hours, shorten check man time more than 42 hours, the upkeep operation carried out during making originally can only to be arranged in equipment annual overhaul utilizes daily periodical repair to complete according to actual conditions, thus more fully ensures equipment operational reliability.
3, the utility model structure is simple, processing and fabricating cost is low, convenient for installation and maintenance.
4, the utility model instrument can be widely used in each heavy and medium plate mill balance weight and change operation, and application value is large.

Fig. 4 is the guide blot schematic diagram in the utility model.
In figure: 1-top backing up roll, 2-lower backing roll, 3-balance weight, 4-track, 5-memorial archway, 6-working roll push-and-pull cylinder, 7-adjustment screw, 8-hook, 9-slide block, 10-hydraulic cylinder, 11-base, 12-guide blot.
Detailed description of the invention
As shown in Figure 3, Figure 4, a kind of specific purpose tool of online dismounting mill balancing block, this instrument comprises guide blot 12, base 11 and establishes adjustment screw 7 on the pedestal 11, slide block 9 with holes, hydraulic cylinder 10.The side of base 11 is provided with hook 8; The cylinder rod end of hydraulic cylinder 10 is connected with slide block 9.
Wherein: the cylinder body end of hydraulic cylinder 10 is connected with base 11 by bolt.The cylinder rod end of hydraulic cylinder 10 is connected with slide block 9 by bearing pin.
Adjustment bolt 7 is connected with base 11 by screw thread.
Hook 8 matches with the gib head on working roll push-and-pull cylinder 6.
During use, first the utility model is placed on track 4, by working roll push-and-pull cylinder 6, the utility model is pushed into the bottom of the balance weight 3 that will change, on the slide block 9 being adjusted the utility model top by hydraulic cylinder 10, the relative position of the cylinder cap of hole and balance weight 3 bottom, exits working roll push-and-pull cylinder 6 from memorial archway 5.Remove two connecting bolts on the top of balance weight 3 and memorial archway 5, its position is installed guide blot 12, use the lifting apparatus of lower backing roll 2, the utility model is lifted to slide block 9 and balance weight 3 when 10mm, stop the lifting of lower backing roll 2, then adjustment bolt 7 of the present utility model is adjusted, slide block 9 is made to abut in the bottom of balance weight 3, secondly remaining connecting bolt of balance weight 3 and memorial archway 5 is removed, by hydraulic cylinder 10 action, balance weight 3 is departed from memorial archway 5, and move in the middle part of the utility model, remove guide blot 12, by working roll push-and-pull cylinder 6, the utility model and balance weight 3 are shifted out memorial archway 5, finally change balance weight, the same manner is adopted during installation.
