Abstract
The utility model discloses a tool for releasing fixing bolts of hot rolls. The tool comprises a handle, a connecting rod and a bolt head, wherein the handle is welded at one end of the connecting rod while the bolt head is welded at the other end of the connecting rod. The tool can be used for detaching the hot rolls without reducing temperature of the hot rolls, can avoid easy scald accidents, and saves more power when being used for releasing the bolts due to the fact that the handle is longer.
Description
Technical field
The utility model relates to a kind of extracting tool, particularly a kind of instrument of dismantling the hot-rolling set bolt.
Background technology
Use hot-rolling to heat to tow in the polyester filament production, hot-rolling is fixed on the hot case base by hexagon socket head cap screw, and heat roller temperature is between 140 ℃-280 ℃ in the production.After breaking down, hot-rolling needs to dismantle down the machine maintenance, if but wait its temperature to be cooled to normal temperature and want about 10 hours, bigger to producing influence; Do not use common die nut heat to tear open if do not wait its cooling, dismounting personnel's hand is very easy to be scalded, and the space is narrow and small in the hot case, bad exerting oneself, dismounting difficulty.
Summary of the invention
The purpose of this utility model is to provide the instrument of a kind of safety, high efficiency, dismounting hot-rolling set bolt easy to use.
The technical solution that realizes the utility model purpose is: the instrument of this dismounting hot-rolling set bolt, and connecting rod one end is welded with handle, and the connecting rod other end is welded with bolt head.The length of connecting rod is greater than hot-rolling length.The length of handle is greater than the hot-rolling diameter.Bolt head be shaped as hexagon, yi word pattern, cross.
The utility model compared with prior art, its remarkable advantage is: (1) connecting rod length is greater than hot-rolling length, in the outside operation of hot case, is difficult for scalding dismounting personnel's hand during dismounting; (2) handle length is dismantled laborsaving greater than the hot-rolling diameter.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, a kind of instrument of dismantling the hot-rolling set bolt described in the utility model comprises handle 1, connecting rod 2 and bolt head 3, and connecting rod 2 one ends are welded with handle 1, and connecting rod 2 other ends are welded with bolt head 3.The length of connecting rod 2 is greater than hot-rolling length.The length of handle 1 is greater than the hot-rolling diameter.Bolt head 3 be shaped as hexagon, yi word pattern, cross.
When needing to dismantle down the machine maintenance after hot-rolling breaks down, select the bolt head and the fixing instrument of the dismounting hot-rolling set bolt that is complementary of the bolt of hot-rolling, in the corresponding groove with the bolt head inserting bolt, swing handle 1 again, make bolt head 3 rotate by connecting rod 2 thereupon, rotate thereby drive bolt, bolt unloads the most at last, has avoided the inconvenience that dismantlement work is brought with spanner demounting bolt high temperature and narrow space.
Connecting rod 2 length in the outside operation of hot case, are difficult for scalding dismounting personnel's hand greater than hot-rolling length during dismounting; Handle 1 length is dismantled laborsaving greater than the hot-rolling diameter.
