Description
Technical field
The utility model relates to a kind of drilling equipment Bolt dismantling device, belongs to the special-purpose maintenance tool technical field of various heterotypic bolts.
Background technology
Development along with drilling technology; Various novel drilling equipment numerous complicated; It is to link together through bolt that a lot of drilling equipments are arranged; These equipment need be dismantled some connecting bolts when safeguarding, and these bolts warps use for a long time or because of interference engagement is difficult to decompose, especially underground equipment is difficult to dismounting through erosion for a long time and wearing and tearing.Present employed method for dismounting, what great majority used is that manual wrench or sledgehammer manual work are knocked, time-consuming, the effort of this method; Extracting tool often occurring skids; Can not take out bolt, even cause the damage of bolt and drilling equipment, cause very big economic loss.
Summary of the invention
The utility model provides a kind of drilling equipment Bolt dismantling device, and it not only can overcome the damage bolt that exists in the prior art and the shortcoming of drilling equipment, and simple in structure; Easy to operate, dismounting speed is fast, does not damage bolt and drilling equipment; Effectively avoid economic loss; Reduce labor intensity, increase work efficiency, shorten maintenance duration.
The utility model is made up of fixing support rack, screw rod, sleeve; Fixing support rack is made up of base, first support bar, second support bar and level board, and the two ends of base have screw, and the middle part of base is provided with draw-in groove; First support bar and second support bar two ends up and down are screw thread; First support bar and second support bar are installed in through screw thread in the screw of base, have through hole on the level board, and the middle part has screw; Level board is plugged between first support bar and second support bar, and fixes through nut; Screw rod top is screw thread, and the middle part has jack, and the bottom is a connector, and screw rod is installed on the screw at level board middle part through its top screw thread; Upper cartridge is and the corresponding link slot of the connector of screw rod bottom that the bottom is provided with and the corresponding joint of bolt to be removed.
The draw-in groove upper surface at base middle part is the conical surface.
The connecting thread pitch of screw rod and level board is identical with the thread pitch of waiting to tear open bolt.
The connector of screw rod bottom is square.
Upper cartridge has and the corresponding square link slot of the connector of screw rod bottom; The joint of bottom is and waits to tear open corresponding groove of bolt shape or boss.
The joint of lower cartridge is inside and outside " plum blossom " shape or inside and outside " ten " font or inside and outside " one " font or inside and outside square or inside and outside three square or inside and outside hexagons.
The beneficial effect of the utility model is: demounting bolt, and quick and convenient, can not damage bolt and drilling equipment, especially be adapted to the dismounting of machinery equipment special shaped screw bolt.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Can be known that by Fig. 1 the utility model is made up of fixing support rack, screw rod 6, sleeve 9, fixing support rack is made up of base 1, the first support bar 2-1 and the second support bar 2-2 and level board 3; The two ends of base 1 have screw; The middle part of base 1 be provided with draw-in groove 4, the first support bar 2-1 and the second support bar 2-2 up and down two ends be screw thread, the first support bar 2-1 and the second support bar 2-2 are installed in the screw at base 1 two ends through screw thread; Level board 3 two ends have through hole; The middle part has screw, and level board 3 is plugged between the first support bar 2-1 and the second support bar 2-2, and fixes through nut 5-1,5-2 and nut 5-3,5-4; Screw rod 6 tops are screw thread, and the middle part has jack 7, and the bottom is a connector 8, and screw rod 6 is installed on the screw at level board 3 middle parts through its top screw thread; Sleeve 9 tops are and the connector 8 corresponding link slots 10 of screw rod 6 bottoms that the bottom is provided with and the corresponding joint 11 of bolt to be removed.
Draw-in groove 4 upper surfaces at described base 1 middle part are the conical surface.
The connecting thread pitch of described screw rod 6 and level board 3 is identical with the thread pitch of waiting to tear open bolt, and the connector 8 of screw rod 6 bottoms is square.
Described sleeve 9 tops have the connector 8 corresponding square link slots 10 with screw rod 6 bottoms; The joint 11 of bottom is and waits to tear open corresponding groove of bolt shape or boss, can be inside and outside " plum blossom " shape, inside and outside " ten " font, and inside and outside " one " font, inside and outside square, inside and outside three is square, inside and outside hexagon.
