Abstract
The utility model relates to a roll changing dolly locking device of a horizontal wire rolling mill. The roll changing dolly locking device is characterized by comprising a locking cap and wedge iron, wherein the locking cap is fixedly arranged on a rolling mill archway, and a through hole is formed in the locking cap and is higher than the top of a pressing plate; and the wedge iron is arranged in the through hole of the locking cap and is vertical to the pressing plate. The roll changing dolly locking device has the advantages of simple structure, reliability in locking and simplicity in disassembly and adjustment and can effectively prevent a hook from being disconnected from a buckling slot.
Description
Technical field
The utility model relates to a kind of wire horizontal mill roll dolly locking device.
Background technology
The flat memorial archway formula rolling mill roll roller of thick, the middle squezzing of high line system is installed on the traversing roll change buggy, and traversing roll change buggy is installed on the horizontal slideway of mill housing, and traversing roll change buggy and mill housing is fixed together by foot-operated hook at transmission side.Traversing dolly is by the transmission side Driven by Hydraulic Cylinder.When the needs roll change; Drive traversing roll change buggy and mill housing traversing through hydraulic cylinder and foot-operated hook to the roll change position; After the foot-operated hook of manual release, hydraulic cylinder drive traversing roll change buggy again roller system and traversing roll change buggy are shifted out mill housing, could change roll.When normal steel rolling maybe need be changed groove, must whether firmly traversing dolly and memorial archway be pinned by the foot-operated hook of running check, otherwise the major accident that groove misplaces or roll breaks away from will occur from memorial archway.Owing to equipment design and processing reason; In steel rolling, change in groove and the roll change operation process; The phenomenon that foot-operated hook and traversing roll change buggy disconnect often occurs, cause groove dislocation, roll disengaging or milling train not to have traversing putting in place, roll change buggy leaves milling train under the effect of hydraulic cylinder; Roll change buggy is broken away from from the milling train slideway, can not accomplish the roll change operation.Therefore, a kind of easy operating, structure order are applicable to that roll roller system and the locking of mill housing or the device that breaks away from become the target that pursue this area.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of the utility model provides a kind of wire horizontal mill roll dolly locking device, and this device can make roll roller system and mill housing secure lock, and a kind of locking device that can break away from fast again.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of wire horizontal mill roll dolly locking device is characterized in that comprise locking cap, drift, locking cap is fixed on the mill housing, which is provided with through hole, and this through hole is higher than the pressing plate top, and drift is arranged in the through hole of locking cap, be provided with vertical with pressing plate.
Compared with prior art, the beneficial effect of the utility model is:
This apparatus structure is simple, can effectively prevent hook and draw-in groove disengagement, reliable lock, and the dismounting adjustment is simple.
Description of drawings
Fig. 1 is the utility model structure front view.
Fig. 2 is the utility model structure vertical view.
Among the figure: the traversing dolly of 1-pressing plate 2-locking cap 3-drift 4-mill housing 5-hydraulic means 6-.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
A kind of wire horizontal mill roll dolly locking device like Fig. 1, shown in 2, comprises locking cap 2, drift 3; Locking cap 2 is fixed on the mill housing 4, which is provided with through hole, and this through hole is higher than pressing plate 1 top; Drift 3 is arranged in the through hole of locking cap 2, with pressing plate 1 vertical setting.
Because foot-operated hook is to be fixed on the mill housing 4, hooks the draw-in groove of traversing dolly 6, makes mill housing 4 as a whole with 6 one-tenth in traversing dolly, realize traversing action through the hydraulic means 5 that is connected with traversing dolly 6.Foot-operated hook is to adopt lever principle to carry out work, and it can only carry out spacing in all around, and above-below direction is freely, takes place frequently exactly because above-below direction is the accident that just causes linking up with the nature disengagement that can't locate.
During use, drift 3 is inserted in the through hole of locking cap 2, make pressing plate 1 fixing, thereby pin the movement tendency of foot-operated hook above-below direction, prevent hook and draw-in groove disengagement, guarantee that mill housing becomes as a whole firmly with roller system.
The utlity model has reliable lock function, volume is little, and easy removal to the working environment no requirement (NR), need not safeguarded, need not adjust.
Above embodiment limits the utility model never in any form, every above embodiment is made with the equivalent transformation mode other improve and use, all belong to the protection domain of the utility model.
