Abstract
The utility model discloses an orifice device for a combined type down-the-hole hammer. The orifice device mainly comprises a connecting rod, a substrate, clamping plates, an auxiliary bolt and a locking bolt; the connecting rod and the substrate from a rectangular base frame; the base frame stretches across an orifice; the clamping plates are arranged on the base frame and are connected together through the auxiliary bolt and the locking bolt; semi-circular concave holes are arranged on the clamping plates; when the two clamping plates are connected, the two semi-circular concave holes form an incomplete circular hole, the radius of which is equal to that of a drill stem; and the convex edge of the drill stem of the combined type down-the-hole hammer is in contact with the end surface of the incomplete circular hole. When the combined type down-the-hole hammer is used for clamping and connecting the drill stem, the orifice device is used for clamping the drill stem connected with the combined type down-the-hole hammer, thereby effectively preventing the down-the-hole hammer from falling into the bottom of a hole.
Description
Technical field
The utility model belongs to down-the-hole hammer technical field, relates to a kind of combined type down-the-hole hammer opening arrangement.
Background technology
In the reverse circulation drilling operation; When spinning rig adjunction drilling rod; The drilling rod that is connected with combined type down-the-hole hammer need separate with the rig that spins, if fixing down-the-hole hammer immediately not can fall at the bottom of the hole just the combined type down-the-hole is hammered into shape; The combined type down-the-hole hammer that falls at the bottom of the hole acquires a certain degree of difficulty when not only taking out, and influences carrying on of bore operation.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of combined type down-the-hole hammer opening arrangement, is used for clamping the drilling rod that is connected with combined type down-the-hole hammer when combined type down-the-hole hammer adds stacks, prevents that effectively the down-the-hole hammer from falling at the bottom of the hole.
The utility model is achieved through following technical scheme.
The described a kind of combined type down-the-hole hammer opening arrangement of the utility model; Mainly be made up of connecting rod, pedestal, clamping plate, auxiliary bolt and lock bolt, connecting rod and pedestal are connected to form a rectangle pedestal, and pedestal is across the aperture; Clamping plate are installed on the pedestal; Two clamping plates links together through auxiliary bolt and lock bolt, and clamping plate are provided with semicircle shrinkage pool, when two clamping plates connects; The two halves circular shrinkage hole is formed the non-complete circular hole that radius equates with the drilling rod radius, and the drilling rod convex edge of combined type down-the-hole hammer contacts with the end face of non-complete circular hole.
Fixed block a is installed on the said pedestal, fixed block b is installed on the clamping plate, be used to limit clamping plate and slide.
Compared with prior art, the technique effect that the utility model reaches is to can be used for clamping the drilling rod that is connected with combined type down-the-hole hammer when combined type down-the-hole hammer adds stacks, prevents that effectively the down-the-hole hammer from falling at the bottom of the hole.
