Abstract
The utility model discloses an underground hole drilling anti-clamping drilling machine which is used under the condition of hydrogeologic hole drill of underground construction in a coal mine. The utility model comprises a drilling head, a drill core pipe, a drilling rod, a motor and an operating handle, wherein the front end of the drilling rod is connected with the drill core pipe and the back end of the drilling rod is connected with the motor. A simulated hammer-shaped hole expansion body is fixedly arranged on the drilling rod, and cutting teeth are evenly arranged on the hole expansion body. The utility model can effectively prevent holes from collapsing so as to lead clamping and drilling accidents.
Description
Technical field:
The utility model relates to the down-hole drilling anti-sticking rig that uses when the construction hydrogeology is holed under a kind of coal mine.
Background technology:
Clear water literary composition geological conditions is visited in construction hydrogeology boring under coal mine, is the important content of mine water prevention work.Present rig by drill bit, drilling rod, motor, operator etc. constitute, in boring of down-hole construction level or inclined drill process, often run into the hole or because the lock of tool drilling that rock water-swellable undergauge causes has a strong impact on rate of penetration of collapsing.
The utility model content:
The purpose of this utility model provides and a kind ofly can prevent the hole of collapsing, and causes the down-hole drilling anti-sticking rig of lock of tool drilling.
To achieve these goals, the utility model comprises: drill bit, core barrel, drilling rod, motor, operator handle, and the drilling rod front end connects core barrel, and the drilling rod rear end connects motor, it is to have fixedly installed an imitative capitate reaming body on drilling rod, evenly is provided with pick on the reaming body.Like this, in the process of creeping into, the effect of open-work is played in the rock that imitative capitate reaming body cutting is collapsed or the rock stratum of expansion undergauge, reaches that boring is not crushed to death, the purpose of bit freezing.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, the utility model comprises: drill bit 1, core barrel 2, drilling rod 4, motor 5, operator are 6, drilling rod 4 front ends connect core barrel 2, drilling rod 4 rear ends connect motor 5, drill bit 1 is positioned at the termination of core barrel 2, on drilling rod 4, fixedly install an imitative capitate reaming body 3, evenly be provided with pick 7 on the reaming body.For the ease of adjusting, imitative capitate reaming body 3 is through on the drilling rod 4 and can moves, and utilizes holding screw will imitate capitate reaming body 3 before working as required and is fixed on that the appropriate location gets final product on the drilling rod.Imitative capitate reaming body adopts antifriction alloy processing, and its external diameter should adapt with drill bit.
