Abstract
The utility model discloses a power driving mechanism used on a drilling rod of a rotary drilling rig. The power driving mechanism comprises a power head and a drilling rod, the power head is sleeved outside the drilling rod, an inner spline is arranged on the circumferential surface inside the power head, and an outer spline is arranged in the position where the outer side of the drilling rod is corresponding to the inner spline of the power head. By contacting the two sides of the inner spline of the power head with the outer spline of the drilling rod and transmitting the corresponding rotating power to the drilling rod, the abrasion of the outer spline of the drilling rod is reduced, the service life of the drilling rod is prolonged, and the maintenance cycle and the replacement cycle of the drilling rod are prolonged; moreover, while guaranteeing the vertical sliding of the drilling rod, the stability of transmitting the power to the drilling rod from the power head is effectively improved, and the impact force to the drilling rod by the power head at the starting moment is reduced. The overall structure is simple and durable, the power transmission is stable and reliable, and the production cost during the excavation process can be greatly reduced.
Description
Technical field
The utility model relates to the rotary drilling rig that uses in a kind of engineering construction, particularly a kind of power drive mechanism that is used on the rotary drilling rig drilling rod.
Background technology
Rotary drilling rig is the efficient pore-forming equipment of heavy caliber that uses in a kind of foundation construction, and the drilling rod that its utilization remains vertical direction directly rotates, excavates ground, thereby forms the stake hole of the required diameter and the degree of depth fast on ground.This rotary drilling rig since power big, power is strong, easy to use, pore-forming is quick, so in the foundation construction process of the engineering of being widely used in, building.But existing this rotary drilling rig in use also has its weak point, particularly on the drive mechanism of drilling rod and unit head, unit head applies unidirectional active force all the time to drilling rod, make drilling rod serious wear in the excavation of once-forming, boring procedure, need often maintenance and change drilling rod, make troubles to use, increased cost of production greatly.How avoiding the generation of this situation, improve drive mechanism and force way between unit head and the drilling rod, is the problem that the utility model need solve.
Summary of the invention
In view of above-mentioned deficiency of the prior art, the utility model aims to provide that a kind of kind of drive is simple, stressed evenly, long service life be used for power drive mechanism on the rotary drilling rig drilling rod.
The utility model is achieved through the following technical solutions:
A kind of power drive mechanism that is used on the rotary drilling rig drilling rod comprises unit head and drilling rod, and unit head is enclosed within the drilling rod outside, and the periphery of unit head inboard is provided with internal spline, and the position corresponding with the unit head internal spline, the drilling rod outside is provided with external key.
Described external key is positioned at the both sides of internal spline.
The quantity of described internal spline is three, and the quantity of external key is six.
Described internal spline is by on the periphery that is bolted to the unit head inboard, and external key is welded on the drilling rod.
A kind of power drive mechanism that is used on the rotary drilling rig drilling rod described in the utility model, utilize unit head internal spline both sides to contact with the drilling rod external key respectively and transmit corresponding rotary power and give drilling rod, reduced the wear rate of external key on the drilling rod, improved the application life of drilling rod, the maintenance and the replacement cycle of drilling rod have been prolonged, and be positioned at the drilling rod external key of internal spline both sides, when guaranteeing the upper and lower slip of drilling rod, effectively improved the stationarity that the unit head transferring power is given drilling rod, reduced the impact force of startup moment unit head drilling rod.Total is simple, durable, and transmission of power is stable, reliable, greatly reduces the cost of production of mining process.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Be further described below in conjunction with 1 pair of the utility model of accompanying drawing:
A kind of power drive mechanism that is used on the rotary drilling rig drilling rod described in the utility model, comprise unit head 1 and drilling rod 2, the periphery of unit head 1 inboard is provided with three internal splines 3, the corresponding position in drilling rod 2 outsides and unit head internal spline 3 both sides is provided with six external keys 4, internal spline 3 is fixedly connected on the unit head 1 inside circumference face by the countersunk head hex bolts, and 4 of external keys directly are welded on drilling rod 2 surfaces.Unit head 1 is enclosed within by internal spline 3 on the external key 4 of drilling rod 2, and unit head 1 can upper and lower slip in six external keys 4 of drilling rod 2 by three internal splines 3.In the course of work, unit head 1 rotation, unit head 1 contacts with the drilling rod external key 4 of a side by internal spline 3 and transmitting rotary power is given drilling rod 2, and drilling rod 2 begins rotation and vertical excavation ground.And when needs reversing drilling rod 2, unit head 1 reverse rotation, unit head 1 contacts with the drilling rod external key 4 of opposite side by internal spline 3 and transmitting rotary power is given drilling rod 2, thereby realized drilling rod external key 4 respectively with the power transmission process of unit head internal spline 3 both sides, reduce the wearing and tearing of drilling rod 2, improved service efficiency.
Claims (4)
1, a kind of power drive mechanism that is used on the rotary drilling rig drilling rod, comprise unit head and drilling rod, unit head is enclosed within the drilling rod outside, it is characterized in that, the periphery of described unit head inboard is provided with internal spline, and the position corresponding with the unit head internal spline, the drilling rod outside is provided with external key.
