Description
Technical field
The present invention relates to mining equipment accessory technical field, specifically driver is mostly used hole head.
Background technique
In expiloration of coal mines or petroleum drilling and mining operation, perforating device i.e. drill bit are critically important one of tools, therefore
The requirement of the junction of perforating device and connecting rod is higher and higher, if perforating device and the connector of connecting rod apply less torque, passes
The ability of passing may result in excessive torque, caused by coefficient of friction it is lower, and excessive torque can tensible, rupture or fracture
Drilling rod leads to the reduced service life of perforating device and connecting rod, and maintenance cost increases, and suchlike accident will all will lead to life
Produce stopping and the damage of equipment；In addition, perforating device junction of connecting rod and perforating device in operation process will appear protrusion,
Resistance is generated in boring procedure, and then influences the entrance of perforating device, causes the abrasion of junction, the connection generallyd use at present
Connection between bar and perforating device is to be threadedly coupled, but threaded connection can not solve the problems, such as the normal use that drilling rod reverses, and long
The screw thread that phase uses be easy to cause screw thread to damage, and carries out repairing button, increases use cost.
Summary of the invention
In order to solve the deficiencies in the prior art, the present invention provides driver to be mostly used hole head, which is mostly used hole head can be real
The reverse rotation of existing perforating device, and connection type is simple, it is easy for assemble or unload, quick-replaceable is realized, is further realized simultaneously
Auxiliary reaming, reduces the abrasion of coupling part, improves service life.

Connector is connected by buckle-type, and two bayonet disks are arranged in the two sides of the perforating device connector, opens up card in each bayonet disk
Slot, the side of bayonet disk are arranged the first limited block, the side setting opposite with the first limited block the on another bayonet disk
Two limited blocks vertically open up the first limit hole on two bayonet disks respectively, and the first limit hole and card slot communicate, on perforating device connector
Installation connection knock-off joint, the outside for connecting knock-off joint are set there are two clamp disk, and two clamp disks are respectively corresponded with two bayonet disks
Cooperate, vertically open up the second limit hole respectively on two clamp disks, the second limit hole is corresponding with the first limit hole, the second limit
Spacer pin is installed altogether in hole and the first limit hole, the top of spacer pin is arranged fixture block, the top of the lower part of fixture block and bayonet disk it
Between tension spring is set；Two driver bodies are arranged in the outside of bayonet disk on the perforating device connector, and the rotation is specially arc steel body,
It revolves and hard alloy is set on specific cutting face, open up limbers between driver body and perforating device connector.
In order to further realize the present invention, the technical solution that can also use are as follows: the driver body is uniformly distributed, mutually
Between angle degree of being.The driver body surface bread is covered with wearproof structural tier.The bayonet disk and clamp disk is sector.Institute
The bottom end for the connection knock-off joint stated opens up round fixing groove.Fixed disk is arranged in the top of the perforating device connector, and fixed disk is in
Circle, the radius of fixed disk are identical as the round radius of fixing groove.The bottom end face of the connection knock-off joint can also be flat
Sliding hemispherical.The radial diameter of the lower end of the connection knock-off joint be subject to be inserted into just it is intracavitary in perforating device connector.
The invention has the benefit that the first limit is respectively set in the side of two bayonet disks of perforating device connector in the present invention
Position block and the second limited block, the first limit block and the second limit block are oppositely arranged, when the clamp of connection knock-off joint spirals card inlet
When in the card slot on disk, the first limit block and the second limit block each serve as positioning action, at this time the second limit on clamp disk
Hole and the first limit hole on bayonet disk are just corresponding, can be inserted into fixed pin, entire to connect perforating device connector and connecting rod
The process of connector, without specially carrying out manual calibration to the first limit hole on the second limit hole and bayonet disk on clamp disk,
The Connection Time is saved, the joint efficiency of drilling rod is improved.In the present invention spacer pin top be arranged fixture block, the lower part of fixture block with
Tension spring is set between the top of bayonet disk, and when spacer pin is located in the second limit hole and the first limit hole, tension spring is in nature shape
State needs when in the card slot for the perforating device connector upper latch notch disk that needs to spiral the clamp on connection knock-off joint first by spacer pin
Lift manually, when clamp spiral card inlet disk card slot in when, put down spacer pin, spacer pin can be automatic by the pulling force of tension spring
It is inserted into the second limit hole and the first limit hole, it is therefore prevented that drilling rod is shaken spacer pin wind out due to vibration in drilling process
Danger, improves the safety coefficient of equipment.Two driver bodies, driver is arranged in the outside of bayonet disk in the present invention on card hole device connector
Body can assist reaming, reduce abrasion of the borehole wall to coupling part, extend service life, effectively form and be mostly used hole to driver
