Abstract
The utility model provides a roll frame screw detacher, the spanner front end of the detacher of constituteing by spanner, spanner and top is equipped with one section outer hexagonal spanner, and the spanner front end has the wedge angle, and the spanner rear end is equipped with circular boss and connecting rod, and flat top hemisphere top is installed on the connecting rod through the intermediate junction hole, and the spanner passes through front end square hole activity suit on the spanner. Inserting a wrench head into a hexagon socket hole in the end of the screw, knocking the top head by a hammer to enable the outer hexagon wrench head to be wedged tightly with the hexagon socket hole in the screw, determining that the wrench rod rotates backwards, pressing the top head at the rear end of the wrench by one hand, adjusting the wrench rod to a position suitable for disassembling the screw by the other hand, and then wrenching the wrench rod to rotate the wrench to unscrew the screw. The utility model discloses can fundamentally solve because the interior hexagonal screw corrosion, twist the problem of the dismantlement difficulty that bald etc. caused, greatly accelerate dismantlement speed, improve the operating efficiency.
Description
Technical field
The utility model belongs to mechanical equipment of steel rolling field, relates in particular to a kind of stripping attachment for hot rolled seamless steel tube rolling mill roll frame attachment screw.
Background technology
PQF tandem mill is 63 roller continous way hot rolled seamless steel tube milling trains introducing from Germany, is provided with 6 groups of roll stand locating pieces in main frame memorial archway, every group of 4 locating pieces, and each locating piece is connected with main frame memorial archway with 4 soket head cap screws (M10 * 35mm).In main frame memorial archway, be also provided with 6 groups of roll stands and import slide rail, every group of 4 one slide rails, every one slide rail is connected with main frame memorial archway with 6 soket head cap screws.Roll stand slide plate also adopts soket head cap screw (M10 * 40mm) to be connected with main frame memorial archway.Add up to 240 interior hexagonal attachment screws.Whenever annual overhaul all will be rolled center line detecting to tandem mill main frame memorial archway, as it is overproof to detect roll line side-play amount, locating piece will be pulled down with the soket head cap screw that slide rail is connected with memorial archway, the method that the quantity by the adjusting pad below locating piece, slide rail increases and decreases is adjusted.The corrosiveness of the steam producing during due to roll cooling water and steel rolling, causes screw inner hexagonal hole physical dimension to increase.During by common outer hexagonal spanner knockout screw, due to excesssive gap between the interior hexagonal of common wrench outer-hexagonal side and screw, cause the inner hexagonal hole of screw twist bald and cannot be disassembled.For this reason, site operation personnel adopts this interior hexagonal of following three kinds of methods dismounting to twist bald screw conventionally:
1, with the edge of chisel shovel screw turret head, slowly shovel out bit by bit.Because screw head is embedded in locating piece or slide rail, chisel is difficult to shovel and arrives; Owing to being subject to the spatial limitation of equipment own, chisel is capable not to be left simultaneously, and screw shovels not out.
2, with electric welding, socket head screw and outer hexagonal spanner are welded together, and then screw is back-outed.Because screw head is imbedded in locating piece or slide rail, the welding current situation will head of screw and locating piece or slide rail welded together and do not tear open not get off.
3, with electric hand drill, head of screw is bored to elimination fastening force, then the remainder of screw is backed out.But removal efficiency is too low in this way, and the used time is oversize, can not meet construction period.
Summary of the invention
The utility model aims to provide a kind ofly can or twist bald soket head cap screw and back-out smoothly corrosion, thereby shortens the take-down time, improves the roll stand device for dismounting screw of operating efficiency.
For this reason, the solution that the utility model is taked is:
A roll stand device for dismounting screw, is characterized in that, spanner, tommy bar and top, consists of; Spanner is the straight-bar of a square section, spanner front end is provided with one section of outer-hexagonal spanner, spanner front end is with key groove, spanner rear end is provided with round boss and connecting rod, flat-top hemispherical top is arranged on connecting rod by middle connecting hole, and the square hole movable set that tommy bar arranges by front end is on spanner.
Width between two planes corresponding to described spanner outer-hexagonal spanner than the large 0.03～0.05mm of width between two planes corresponding to the soket head cap screw of dismantling, the little 0.2mm of size between diagonal angle.
Screw disassembling method of the present utility model and beneficial effect are:
During knockout screw, outer-hexagonal spanner is inserted in the inner hexagonal hole of screw termination, then knock spanner rear end top with hand hammer, in spanner outer-hexagonal spanner wedging screw inner hexagonal hole; After determining tommy bar rotation direction, dismounting personnel live spanner rear end top with a hand, and another hand is adjusted to tommy bar the position that is applicable to knockout screw, can pull tommy bar rotary spanner screw disassembling is got off.
The utility model can once be back-outed screw smoothly, has fundamentally solved due to soket head cap screw corrosion, has twisted the problem of the dismounting difficulty causing such as bald, greatly adds Quick demounting speed, improves operating efficiency, for shortening the annual overhaul time, provides prerequisite.
Accompanying drawing explanation
Fig. 1 is spanner stereogram;
Fig. 2 is stripping attachment stereogram.
In figure: key groove 1, spanner 2, spanner 3, top 4, boss 5, tommy bar 6.
The specific embodiment
As seen from Figure 1, the utility model roll stand device for dismounting screw system is comprised of spanner 3, top 4 and tommy bar 6.
Spanner 3 is the straight-bar of a square section, and spanner 3 front ends are provided with one section with the spanner 2 of outer-hexagonal side, and the front end of spanner 2 is also processed with key groove 1, so that spanner 2 can be wedged in the inner hexagonal hole of screw termination smoothly.The rear end of spanner 3 is provided with one round boss 5 and one section of connecting rod.Top 4 is hemispherical, and hemispheric top is processed with flat-top, and in the middle of lower surface, with connecting hole, top 4 is interference fitted on the connecting rod of spanner 3 by middle connecting hole hot charging.Tommy bar 6 rear portions, with long handle, are provided with square hole in the middle of foward dome, tommy bar 6 passes through square hole movable set on spanner 3, and can move up and down as required position.
Total corresponding six faces between two of the outer-hexagonal spanner 2 of spanner 3, the width between two corresponding planes than the large 0.03～0.05mm of width between two planes corresponding to the soket head cap screw of dismantling, the little 0.2mm of size between diagonal angle.For example, for the width between two planes corresponding to soket head cap screw, be 8.3mm, between diagonal angle, be of a size of 9.5mm, the width between 2 two corresponding planes of outer-hexagonal spanner is 8.33～8.35mm, is of a size of 9.3mm between diagonal angle.
