Description

Rotary drill drill chuck device

Technical field

Winning equipment is the utility model is related to, in particular to a kind of rotary drill drill chuck device.

Background technology

Rotary drill is mainly used in big-and-middle-sized outdoor metal and nonmetal deposits mountain as a kind of high-efficient perforating equipment.Half Since individual century, outdoor perforating apparatus development experience " brill of kowtowing ", flame is bored and impact (down-the-hole) is bored, final rotary drill with The perforating apparatus that the advantages that penetration hole diameter is big, piercing efficiency is high is commonly used as big-and-middle-sized opencut.

During work, the drilling tool of rotary drill passes through damper and virtual calibrator for instrument transformer and drill bit spiral shell by more drilling rods (generally two) Line is formed by connecting.Because of drilling cramp height limitation, when the transition of rig long range or climbing, it is necessary to dismantle drilling tool, therefore match somebody with somebody on rig It is arranged with drilling tool provision for disengagement.Generally, drilling tool provision for disengagement includes the dop dress of fixed lower drilling tool (drilling tool thread connection bottom) Put the big clamp device of fluid power with the upper drilling tool (drilling tool thread connects top) of dismounting.The structure of the chuck device of drilling tool under existing fixation As shown in figure 1, two clamping grooves for being separated by 180 degree 10 are offered on the lower drilling tool circumference of drilling tool 9, positioned at the drilling tool 9 Both sides are each provided with the dop 11 of a projection shape being adapted with the clamping groove 10.When dismantling drilling tool, stretched in dop Under oil cylinder effect, both sides dop stretches out to drilling tool, and the clamping groove position of drilling tool, realizes the clamping fixed to drilling tool under clamping, Then reuse the big clamp device of fluid power and screw on drilling tool, complete drilling tool dismounting action.In this structure type, due to drilling tool wall thickness compared with Small, the clamping groove that can be opened is shallower, and contact surface is small between clamping groove and dop, after long-time use, dop serious wear, easily There is skidding, chuck device is difficult to block lower drilling tool.

The content of the invention

The purpose of this utility model seeks to provide a kind of hydraulic clamp device for rotary drill dismounting, the device energy Drilling tool under firm clamping, and simple in construction, maintenance facility.

To achieve the above object, rotary drill drill chuck device of the present utility model, for the brill in rotary drill Tool carries out clamping fixed, and it includes dop mounting platform, and the dop mounting platform is provided with clamp installing plate and clamp stretches Oil cylinder, clamp structure is fixed with the clamp installing plate, fixed bayonet socket, the fixed bayonet socket are provided with the clamp structure Clamping stress surface be plane；The clamp installing plate is connected with the piston rod of the clamp telescopic oil cylinder.

Further, the clamp structure is unilateral clamp, and the fixation bayonet socket to take the shape of the letter U is provided with the unilateral clamp；Institute Stating clamping stress surface includes preceding clamping face and rear clamping face, being connected with arc surface between the preceding clamping face and the rear clamping face, institute Clamping face before stating, the arc surface and the rear clamping face connect and compose the fixed bayonet socket together.

Further, the clamp installing plate includes the first left installing plate and the first right installing plate, the fixed bayonet socket bag The the first left bayonet socket and the first right bayonet socket for coordinating clamping are included, the clamp structure includes the symmetrically arranged first left clamp and first Right clamp, the first left clamp are fixed on the described first left installing plate, and it is right that the first right clamp is fixed on described first On installing plate, the first left bayonet socket is located on the described first left clamp, and the first right bayonet socket is located at the described first right clamp On.

Further, the described first left bayonet socket and the first right bayonet socket take the shape of the letter U respectively.

Further, the clamp installing plate includes the second left installing plate and the second right installing plate, the fixed bayonet socket bag The the second left bayonet socket and the second right bayonet socket for coordinating clamping are included, the clamp structure includes the symmetrically arranged second left clamp and second Right clamp, the second left clamp are fixed on the described second left installing plate, and it is right that the second right clamp is fixed on described second On installing plate, the second left bayonet socket is located on the described second left clamp, and the second right bayonet socket is located at the described second right clamp On.

Further, the described second left bayonet socket includes left arc surface and in plane left front clamping face, second right side Bayonet socket includes right arc surface and in clamping face behind the plane right side.

Further, side relative with the clamp installing plate on the dop mounting platform is provided with clamp chute, The unilateral clamp is limited in the clamp chute.

The utility model utilizes fork spanner principle,, can firm clamping when screwing on drilling tool by drilling tool under fixed bayonet socket clamping Lower drilling tool, effectively prevent lower drilling tool from rotating, the fast quick-detach of drilling tool in realization；The utility model is by by chuck device and drilling tool Clamping contact position is modified to fix bayonet shape, and sets the stress surface of bayonet socket as the structure of plane, with improved drilling tool drilling rod On the plane card access surface that opens up mutually fully coordinate, solve in the prior art because drilling tool wall thickness is smaller, can slot shallower, skid The problem of phenomenon is serious；Meanwhile the utility model avoids perforation and made without setting spring in dop oil cylinder front end dop position The rock slag ejected during industry causes dop oil cylinder front end dop can not be overhanging, the problem of so as to lose snap action；This practicality is new Type is simple in construction, and clamping is reliable, maintenance facility.
