Description
Technical field
The present invention relates to the perforating device field of grouting construction, relate in particular to a kind of engineering the drilling device.
Background technology
In engineering construction, often adopt grout construction method to carry out consolidation process to foundation.The following technological process of the general employing of grouting construction: cloth hole → Grouting Pipe → sealing → slip casting → end slip casting of punching → bury underground → rise and pull out Grouting Pipe → sealing of hole.Punching; be in definite grout hole position, use the method for engineering drill hole of drilling machine or sledgehammer strike at hole of underground formation, to ensure that Grouting Pipe can reach predetermined depth location; conventional engineering driller punches; area occupied is excessive, mobile difficulty, complex operation; operating personnel's labour intensity is large; it is convenient not to use, and more existing perforating devices exist bit freezing, lack in addition the safeguard measure after drill slipping.
Summary of the invention
The object of this invention is to provide a kind of engineering the drilling device, solve by the present invention that perforating device volume was large in the past, inconvenient operation, bit freezing, uses unsafe technical problem;
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
A kind of engineering the drilling device, comprise ramming head, drilling rod and drill bit, described ramming head below is provided with Connection Block, described drilling rod is connected with described Connection Block by vibration head, described drill bit is arranged on the end of drilling rod, and drill bit is connected with drill rod thread, it also comprises buffer, described buffer is sleeved on drilling rod, and buffer is between drill bit and Connection Block, described buffer comprises fixed head, spring and location-plate, described fixed head is connected with described drill rod thread, and fixed head below is provided with spring, described spring below is connected with location-plate,
The present invention, by buffer, ensures drill bit in use, and the hard objects generation of encountering in ground is skidded, thereby damage machine, the spring of buffer the inside can play cushioning effect, makes staff in the time there are special circumstances, can be good at operating machines, avoid fortuitous event.
On the basis of technique scheme, the present invention can also do following improvement.
Further, it also comprises flight, and described flight is connected with drill bit by pivot, adopts the beneficial effect of this step to be, in the time of downward drilling well, the bottom of described flight is subject to boring the pressure of layer thing and described flight is opened and makes the diameter of the variable part of described flight become large around pivot; Described in the time upwards promoting drill bit, the top of flight is subject to boring the pressure of layer thing and around pivot closure, the diameter of the variable part of described flight is diminished described flight unit, is convenient to take out, and can prevent like this bit freezing;
Further, the end of described drill bit is taper, and tapering is 30-45 °.
The invention has the beneficial effects as follows:
1. buffer of the present invention can facilitate staff can better control machine, avoids the generation of fortuitous event;
2. the present invention, by the cooperation of flight and pivot, can effectively prevent bit freezing, has ensured the normal operation of machine;
3. apparatus of the present invention strong adaptability, punching speed is fast, and operating efficiency is high, and economic benefit is high.
