Abstract
The utility model discloses a drill rod pulling device, which is characterized in that the drill rod pulling device comprises a clamp and a locking device. The clamp has two U-shaped clamping plates which are connected by the locking device. The clamp is locked at the flange position of steel drill by screws. The locked steel drill can be pulled out by prying or knocking the clamp with the help of the tools of crowbar, iron hammer and so on. The drill rod pulling device has simple structure and is easy to be operated.
Description
Technical field
The utility model relates to a kind of pricker device that pulls out.
Background technology
In excavation such as mine, railway, water power, military engineering or construction work, drill rod often appears, bore pricker etc. stuck rock or in.At present, handle this stuck in rock drill rod, bore pricker, more medium-sized and small enterprises adopt explosion to remove or with the method that sledgehammer is pounded, adopt this method, the work plane of cutting is damaged or damages drill rod, bore pricker.The then high drill drawing machines of special-purpose cost that adopt of large enterprise take out stuck drill rod, brill pricker more.Chinese patent publication number: CN87206403U discloses a kind of drill drawing machine, by adopting holder part and screw mandrel ejection part to be grouped into, anchor clamps adopt hydraulic booster mechanism, reliably lock drill rod, screw mandrel ejects part and adopts manually, and is equiped with thrust bearing between nut and stop sleeve.Adopt this drill drawing machine can effectively extract stuck drill rod, but complex structure, cost are high.
The utility model content
The utility model aims to provide a kind of simple in structure, and that can effectively extract stuck drill rod pulls out the pricker device.
The technical scheme that the utility model adopted is: a kind of pricker device that pulls out, it is characterized in that, and comprise anchor clamps and locking device; Described anchor clamps are two U type clamping plate, and two clamping plates connects by locking device.
Described locking device is a screw.
The shape at a described U type clamping plate bottom portion of groove and a hexahedral angle matches.
The beneficial effects of the utility model are: by screw anchor clamps are locked at drill rod flange place, use instruments such as crowbar, iron hammer evenly to prize or knock anchor clamps then, stuck drill rod can be extracted, and simple in structure, easy operating.
Description of drawings
Accompanying drawing 1 is a kind of structural representation that pulls out the pricker device of the utility model;
Accompanying drawing 2 is a kind of pricker device lock set sequential schematic of pulling out of the utility model;
Accompanying drawing 3 is a kind of work schematic diagram that pulls out the pricker device of the utility model.
The specific embodiment
The structure of an embodiment of the utility model, shown in accompanying drawing 1 to 3, a kind of pricker device that pulls out is made up of anchor clamps and locking device; Described anchor clamps are two U type clamping plate 2, and the shape at groove 3 places of U type clamping plate 2 and the profile of drill rod adapt, and for common hexahedron drill rod, the triangle that the shape at an angle of hexahedron drill rod matches can be made in the bottom of U type clamping plate 2 grooves.In the time of work, match with two facades of the bottom groove of another piece U type clamping plate 2 and U type clamping plate 2 and to form six, the hexahedron drill rod is firmly held tightly.The material of U type clamping plate 2 can adopt steel plate.On U type clamping plate 2, be provided with some corresponding screws 6.Described locking device is a screw 1, and screw 1 utilizes screw 6, two U type clamping plate 2 can be locked reliably or unclamp.
In real work, the shape of drill rod 4 has multiple shapes such as circle, hexagon, twist shape, and therefore, anchor clamps groove of the present utility model can be made plurality of specifications according to the shape of drill rod 4, satisfies different needs.In the time of work, when needs are extracted stuck drill rod 4, two U type clamping plate 2 can be stuck in flange 5 places of drill rod 4, because the shape at groove 3 places of U type clamping plate 2 and the profile of drill rod 4 adapt, so anchor clamps can be stuck in flange 5 places of drill rod 4 reliably.By screw 1 two U type clamping plate 2 are locked then.Utilize instruments such as crowbar or iron hammer at last, evenly prize or knock anchor clamps, until extracting whole drill rods 4.
Claims (3)
