Abstract
The invention discloses a hemispherical drill stem for a rotary drilling rig. The hemispherical drill stem comprises a cylindrical drill stem body, wherein the upper end of the drill stem body is provided with a shock absorbing ring; the top of the shock absorbing ring is provided with a flat head; the drill stem body is provided with a guide driving groove; the lower end of the drill stem body is provided with a spherical hinge joint; the front end of the drill stem body between the guide driving groove and the spherical hinge joint is provided with a compression spring; the spherical hinge joint is provided with a connecting lock hole; the end part where the cylindrical drill stem body is hinged with a drilling jig is hemispherical; and the spherical hinge joint is provided with a hinge hole for fixing and transferring power provided by a power head along the diameter direction of the spherical hinge joint. By connecting the spherical hinge joint with the drilling jig, the drill stem has the advantages of more uniform stress between the drill stem and the drilling jig, more stable connection and capability of reducing the incidence rate of damaging equipment due to abrupt failure of the hinge joint of the drill stem during the construction.
Description
Technical field
The present invention relates to a kind of rotary drilling rig drilling rod, specifically, relating to a kind of front end is hemispheric rotary drilling rig drilling rod.
Background technology
In the engineering construction process in modern times, the utilization of rotary drilling rig is more and more, and particularly in building and municipal field, and drilling rod is the vitals of rotary drilling rig work.Yet what adopt usually being connected of traditional rotary drilling rig drilling rod and drilling tool is that square toes and drilling tool are connected through the hinge; Because the singularity of drilling rod square toes structure; This connected mode is easy to produce stress and concentrates, and particularly the concentrated angle point of stress is accelerated because of physical-chemical reaction makes corrosion toward contact easily.In the member of existing rotary drilling rig, drilling rod is one of parts that damage the most easily, and the inefficacy of drilling rod and tool joint not only can delay man-hour, also possibly damage unit head and drilling tool indirectly when serious, brings inconvenience to construction.
Summary of the invention
In order to address the above problem; It is hemispheric rotary drilling rig drilling rod that the present invention provides a kind of front end; This structure makes drilling rod and drilling tool stressed more even, and when axial force was big, the semispherical surface of drilling rod can also be along its radial direction dispersion stress; The possibility that reduction equipment is impaired improves the stability of rotary drilling rig work.
Technical scheme of the present invention is: it comprises cylindrical drilling rod body; Drilling rod body upper end is provided with shock ring; The shock ring top is provided with homalocephalus, and the drilling rod body is provided with the guiding driver slot, and drilling rod body lower end is the globular hinge head; Drilling rod body front end between guiding driver slot and the globular hinge head is provided with the compression spring; The globular hinge head is provided with the connection lockhole, and cylindrical drilling rod body is hemispherical with the end that drilling tool is hinged mutually, on globular hinge head diametric(al), has a hinge hole that is used for fixing and transmits the power that is provided by unit head.
Below be further improved preferred version: globular hinge head radius is identical with the radius of cylindrical drilling rod body.
During assembling, the globular hinge head links to each other through hinge axis with the supporting hole slot in drilling tool rear end, and hinge axis passes the hinge hole of said hemispherical articulated joint simultaneously.Because the globular hinge head is hemispherical with the end that drilling tool is hinged mutually; And hinge hole is positioned on its diametric(al); Make hinge axis and globular hinge head have maximum contact area; Thereby make its transferring power stably with the drilling tool cooperating time, and make it under identical material and similar structures condition, have better intensity.In addition, the globular hinge head when assembling with drilling tool, can play guide effect because its front end is hemispherical well, reduces the wearing and tearing in the course of work.
Said shock ring can effectively reduce the vibration that is passed over through drilling rod by drilling tool, guarantees the stable operation of complete machine.And the compression spring that is positioned at drilling rod body front end can match with the drilling tool of rotary drilling rig, adjusts the stressed of drilling tool in good time, improves the compliance of drilling tool piling.
The present invention adopts the globular hinge head to link to each other with drilling tool, and stressed more even between drilling rod and the drilling tool connects more stablely, has reduced in the work progress catastrophic failure of drilling rod articulated joint and the incidence of damage equipment situation.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention;
Fig. 2 is embodiment illustrated in fig. 1 and drilling tool fit sketch map.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
With reference to Fig. 1; Present embodiment comprises cylindrical drilling rod body, and drilling rod body upper end is provided with shock ring 2, and shock ring 2 tops are provided with homalocephalus 1; The drilling rod body is provided with guiding driver slot 3; Drilling rod body lower end is a globular hinge head 6, and the drilling rod body front end between guiding driver slot 3 and the globular hinge head 6 is provided with compression spring 4, and globular hinge head 6 is provided with and connects the lockhole (not shown); Cylindrical drilling rod body is hemispherical with the end that drilling tool is hinged mutually, on globular hinge head 6 diametric(al)s, has a hinge hole 5 that is used for fixing and transmits the power that is provided by unit head.
The radius of globular hinge head 6 is identical with the radius of cylindrical drilling rod body.
With reference to Fig. 2; When assembling with rotary drilling rig; The drilling rod body cooperates binding through the guiding driver slot 3 on it with unit head 8; The hemispherical articulated joint 6 of drilling rod body front end matches with drilling tool 7 corresponding hole slots, and adopts hinge axis to be hinged, and the homalocephalus 1 of the drilling rod body other end links to each other with hoist engine with pulley through steel wire; Unit head 8 links to each other with the mast 9 of rig through support platform.
The present invention adopts the globular hinge head to link to each other with drilling tool, and stressed more even between drilling rod and the drilling tool connects more stablely, has reduced in the work progress catastrophic failure of drilling rod articulated joint and the incidence of damage equipment situation.
