Purpose of the present invention is exactly the defective that exists at prior art, and a kind of safe coring bullet pulling device of simple in structure, with low cost, safe ready is provided.
Its technical scheme is: the present invention is by the main body 1 of choosing, threaded rod 2, dwang 8, extractor set 3, fixture 6, the drill rod 4 of choosing, fixedly drill rod 5 and set bolt 7 are formed, the main body of choosing 1 is drum-shaped structure, Open Side Down, the top plan center of the main body of choosing 1 is provided with screwed hole 11, and its bottom is provided with two slots 13 of symmetrical distribution and two screwed holes 12 that are symmetrically distributed; Extractor set 3 is a drum-shaped structure, and Open Side Down, and the top plan center of extractor set 3 is provided with shaft hole 31, and threaded rod 2 passes shaft hole 31, and its bottom is provided with two jacks 32 of symmetrical distribution, is installed with the drill rod 4 of choosing in this jack 32; Threaded rod 2 lower ends are welded with rounded tabs, and the shaft hole 31 at extractor set 3 top plan centers is passed in its upper end, and pass the screwed hole 11 at the main body 1 top plan center of choosing through screw thread rotation after, are welded to connect with the middle part of dwang 8; Fixture 6 is made as two, and its top is by set bolt 7, and the screwed hole 12 that is symmetrically distributed with main body 1 bottom of choosing is connected, and its underpart is provided with the drill rod hole, is installed with fixedly drill rod 5 in the drill rod hole.
The present invention is closed the bullet of coring, and cores bullet when accident emits even make, and can not hurt the maintenance personal yet, and can extract non-launched warhead easily, safety not only, and also simple to operate, have good use value.
Four, description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention;
Fig. 2 is the structural representation of main body of choosing among Fig. 1;
Fig. 3 is the structural representation of extractor set among Fig. 1.
Five, the specific embodiment
As shown in Figure 1-Figure 3, a kind of safe coring bullet pulling device, by the main body 1 of choosing, threaded rod 2, dwang 8, extractor set 3, fixture 6, the drill rod 4 of choosing, fixedly drill rod 5 and set bolt 7 are formed, the main body of choosing 1 is drum-shaped structure, Open Side Down, the top plan center of the main body of choosing 1 is provided with screwed hole 11, and its bottom is provided with two slots 13 of symmetrical distribution and two screwed holes 12 that are symmetrically distributed; Extractor set 3 is a drum-shaped structure, and Open Side Down, and the top plan center of extractor set 3 is provided with shaft hole 31, and threaded rod 2 passes shaft hole 31, and its bottom is provided with two jacks 32 of symmetrical distribution, is installed with the drill rod 4 of choosing in this jack 32; Threaded rod 2 lower ends are welded with rounded tabs, and the shaft hole 31 at extractor set 3 top plan centers is passed in its upper end, and pass the screwed hole 11 at the main body 1 top plan center of choosing through screw thread rotation after, are welded to connect with the middle part of dwang 8; Fixture 6 is made as two, and its top is by set bolt 7, and the screwed hole 12 that is symmetrically distributed with main body 1 bottom of choosing is connected, and its underpart is provided with the drill rod hole, is installed with fixedly drill rod 5 in the drill rod hole.The two ends of dwang 8 also are provided with labour contractor 81, the convenient use.
Use when of the present invention, make choose main body 1 and the extractor set 3 of device aim at the bullet of coring that to choose, bullet is enclosed in the inside, utilize the drill rod 4 of choosing to pass jack 32 on core bullet and the extractor set 3.Again with fixed part 6, fixed screw 7 and fixedly drill rod 5 pulling attachment is fixed on the sidewall coring tool, the maintenance personal rotates dwang 8 and drives threaded rod 2 with hand, utilizes the transmission principle of leading screw, and the bullet of coring is pulled away the corer coyote hole.At this moment, even the bullet of coring emits, can not hurt the maintenance personal from the coyote hole of coring yet.
