Abstract
The utility model discloses an anchor rod drill capable of broaching. The anchor rod drill comprises a drill rod and a drill bit, wherein a connecting sleeve is arranged between the drill rod and the drill bit; an expansion drill bit is arranged in the connecting sleeve; a long groove which enables the expansion drill bit to extend out is formed in the connecting sleeve; the head end of the expansion drill bit is connected with the connecting sleeve, and the tail end of the expansion drill bit is hinged with the head end of a connecting rod; and the tail end of the connecting rod is connected with a power mechanism. According to the anchor rod drill capable of broaching, by means of hydraulic expansion, the expansion drill bit is extended out of the connecting sleeve, a soil mass is subjected to mechanical cutting, and an anticipated purpose is finally achieved; and the connecting sleeve is arranged between the drill rod and the drill bit, and the expansion drill bit which can be opened or retract through the power mechanism is arranged in the connecting sleeve, so that the structure is simple, and the use is convenient.
Description
Technical field
The utility model relates to a kind of drill bit, but relates in particular to a kind of anchor bit of reaming.
Background technology
Traditional anchor bit from first to last is a diameter, can only get out the hole of bit diameter size during use; And emerging a kind of reaming bit is to utilize water under high pressure mud cutting soil, but cement paste is disposable, causes bigger waste.
The utility model content
But the purpose of this utility model provides a kind of hole reaming of anchor rod drill bit simple in structure.
For achieving the above object, the technical solution adopted in the utility model is:
But a kind of anchor bit of reaming, comprise drilling rod and drill bit, between described drilling rod and drill bit, be provided with adapter sleeve, be provided with the expansion drill bit in the adapter sleeve, offer on the adapter sleeve to make and enlarge the elongated slot that drill bit stretches out, enlarge the drill bit head end and be connected with adapter sleeve, it is hinged to enlarge drill tip and connecting rod head end, and connecting rod is terminal to be connected with actuating unit.
Described expansion drill bit and connecting rod have two groups and be symmetricly set in the adapter sleeve.
Described expansion drill bit head end is hinged with the fixed head that is arranged in the adapter sleeve, and connecting rod is terminal hinged with the pushing plate that is arranged on the dynamic structure.
Described actuating unit is hydraulic cylinder, and described pushing plate is connected with the hydraulic cylinder output.
The utility model is to utilize hydraulic dilatation, will enlarge drill bit and stretch out in adapter sleeve, carries out the machine cuts soil body, finally reaches its intended purposes; The utility model is by being provided with adapter sleeve between drilling rod and drill bit, be provided with the expansion drill bit that can open or withdraw by power set in the adapter sleeve, and is simple in structure, easy to use.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, but a kind of anchor bit of reaming, comprise drilling rod 7 and drill bit 1, between described drilling rod 7 and drill bit 1, be provided with adapter sleeve 3, be provided with expansion drill bit 2 in the adapter sleeve 3, offer the elongated slot 32 that expansion drill bit 2 is stretched out on the adapter sleeve 3, it is hinged with the fixed head 31 that is arranged in the adapter sleeve 3 to enlarge drill bit 2 head ends, it is terminal hinged with connecting rod 21 head ends to enlarge drill bit 2, and connecting rod 21 is terminal hinged with the pushing plate 41 that is arranged on the dynamic structure 4.Described expansion drill bit 2 and connecting rod 21 have two groups and be symmetricly set in the adapter sleeve 3.Described actuating unit 4 is hydraulic cylinder, and described pushing plate 41 is connected with the hydraulic cylinder output.
During the utility model work, when non-anchoring section is resting position, hydraulic pump is opened oil return pipe 6, hydraulic cylinder is back to least significant end, enlarges drill bit 2 contractings in adapter sleeve 3, enlarges drill bit 2 together with outside adapter sleeve 3, only as the part of drilling rod 7, creep into jointly with drilling rod 7, at this moment, bore diameter is 150mm; In anchoring section (expansion drill bit 2 operating positions): hydraulic pump is opened oil inlet pipe 5, hydraulic cylinder progressively pushes up to most significant end, enlarge drill bit 2 under the cylinder pressure effect, progressively launch by connecting rod 21, be extended to 300mm ~ 450mm, this moment, rig only dallied, and added big yield, hydraulic pressure, will not wait to enlarge and continue again to creep into after drill bit 2 launches fully to advance.Behind the drilling to completion, recirculated water is closed, open high-pressure blast, mud in the hole is blown out, enlarge drill bit 2 and get back to inactive state, withdraw from drilling rod 7.The utility model utilizes recirculated water and the acting in conjunction of telescopic expansion cutting blade, cuts out the anchor pole expanded hole, is applicable to general soil layer, also applicable to layer of sand.
Claims (4)
