Abstract
The utility model discloses a replacement trolley for a balance block of a working roll, which comprises a trolley body provided with a width adjusting device for a balance block fixing plate, a traction piece and wheels; the vehicle body is respectively connected with the traction piece and the wheels. The utility model provides a pair of dolly is changed to working roll balancing piece, this dolly can be used to dismantle or mounting panel strip mill working roll balancing piece, very big intensity of labour who has alleviateed the maintenance of equipment personnel has improved work efficiency.
Description
Technical field
The utility model relates to board rolling apparatus for production line technical field, specifically is that a kind of working roll balance weight is changed dolly.
Background technology
The strip-mill strip working roll balance weight of steel rolling mill generally is embedded in the mill housing, and working roll is through the variation of balance weight hydraulic cylinder realization roll gap, and hydraulic cylinder acts frequently; Be prone to take place the problem of bad seals, the leakage problem needs occur and in time change, in the mill housing of living in; Can't use driving, generally in memorial archway, set up crossbeam at present, the employing chain hoist is accomplished the installation and removal work with mill housing; Because the balance weight volume is big, locus of living in is narrow and small, dismounting, centering, centering difficulty; The maintenance dismounting time needs 24 hours at least, causes operating efficiency low.
Summary of the invention
The purpose of the utility model is to be used for solving the prior art working roll to change the process difficulty, and problems such as inefficiency provide a kind of simple in structure, easy to use, and the working roll balance weight of high efficiency is changed dolly.
A kind of working roll balance weight according to the utility model provides is changed dolly, comprising:
Be provided with car body, traction piece and the wheel of balance weight fixed head width adjusting device;
Said car body is connected with said traction piece and wheel respectively.
Further, said car body also comprises:
Carry base, said balance weight fixed head width adjusting device is arranged on the said carrying base.
Further, said balance weight fixed head width adjusting device comprises:
Width adjusting handle, pinion and rack and balance weight fixed head;
Said width adjusting handle is connected with said balance weight fixed head through said pinion and rack.
Further, said traction piece is that head is a hook formation, and afterbody is connected with said carrying base.
A kind of working roll balance weight that the utility model provides is changed dolly, and this dolly can be used for dismounting or installing plate hoop mill working roll balance weight, has alleviated plant maintenance personnel's labour intensity greatly, has improved operating efficiency.
Description of drawings
Fig. 1 changes the vehicle structure sketch map for a kind of working roll balance weight that the utility model provides;
Fig. 2 is the left view of structure shown in Figure 1.
The specific embodiment
Like Fig. 1, shown in Figure 2, a kind of working roll balance weight that the utility model provides is changed dolly, comprises the car body, traction piece 1 and the wheel 3 that are provided with balance weight fixed head width adjusting device 5.Car body is connected with traction piece 1 and wheel 3 respectively.Car body also comprises carrying base 2, and balance weight fixed head width adjusting device 5 is arranged on and carries on the base 2.Balance weight fixed head width adjusting device 5 comprises width adjusting handle 4, pinion and rack and two balance weight fixed heads 6.Balance weight fixed head width adjusting device 5 adopts the opening degree of width adjusting handle 4 adjusting gear rackwork adjustment piece fixed heads 6.Wheel 3 matches with the work roll changing roller-way.Traction piece 1 is that head is a hook formation, and afterbody is connected with said carrying base.When changing balance weight, traction piece 1 matches with the work roll changing dolly, is connected with the work roll changing dolly through the head hook formation.
During the dismounting balance weight; Earlier the abrasion-proof backing block of balance weight is removed; Remove the set bolt of balance weight and mill housing again, change dolly with working roll working roll balance weight replacing dolly is pushed milling train, utilize width adjusting handle 4 adjustment piece fixed heads 6 positions; Utilize bolt that working roll balance weight and balance weight fixed head 6 is fixing; Utilize width adjusting handle 4 to regulate the working roll balance weight is pulled out memorial archway with balance weight fixed head 6, change dolly with working roll at last and working roll balance weight replacing dolly is pulled out milling train, can dismantle a pair of working roll balance weight simultaneously through the head hook formation; Simple possible has alleviated plant maintenance personnel's labour intensity greatly.
When balance weight is installed; With driving lifting working roll balance weight, utilize bolt that working roll balance weight and balance weight fixed head 6 is fixing, with working roll replacing dolly the working roll balance weight is changed dolly again and push milling train; Centering is changed the height decision of dolly by the working roll balance weight up and down; Left and right sides centering is accurately controlled by working roll dolly encoder, utilizes width adjusting handle 4 to regulate and the working roll balance weight is pushed memorial archway with balance weight fixed head 6, the set bolt between dismantlement work roller balance weight and the balance weight fixed head 6; The set bolt of balance weight and mill housing is installed; The abrasion-proof backing block of balance weight is installed again, is changed dolly with working roll at last and working roll balance weight replacing dolly is pulled out milling train, a pair of working roll balance weight can be installed simultaneously through the head hook formation of traction piece 1; Reduce the time of changing the working roll balance weight greatly, improved operating efficiency.
A kind of working roll balance weight that the utility model provides is changed dolly, and this dolly can be used for dismounting or installing plate hoop mill working roll balance weight, has alleviated plant maintenance personnel's labour intensity greatly, has improved operating efficiency.
The foregoing description is the utility model preferred implementation; But the embodiment of the utility model is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit and the principle of the utility model, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of the utility model.
