Abstract
The utility model relates to a drill rod driving buffer device used on a horizontal directional drilling machine. The drill rod driving buffer device comprises a spline shaft, a sliding shaft, two buffer springs and a spring seat. The spline shaft is provided with a drive gear and is supported in a power head container through two bearings. The sliding shaft passes through the spline shaft and is connected through a spline. Both ends of the sliding shaft are respectively provided with a buffer spring, wherein one end is axially positioned by a round nut and a stop washer, and the other end is connected with a drill collar. The impact generated during the operation of the drilling machine is buffered by the spring firstly, and then the impact is passed to the power head, which can effectively reduce the damage of the impact to the drill rod screw and the power head. The drill rod driving buffer device has simple structure and convenient maintenance; with the adoption of the mechanism device, the work is reliable.
Description
Technical field the utility model relates to the drilling rod that uses on a kind of horizontal directional drilling machine and drives buffer.
Background technology is present, and domestic horizontal orientation drill power head generally only has the function that drives drilling rod, in the course of the work, or when changing drilling rod, can produce impact force.This impact force action is at unit head casing and drill rod thread place, the life-span of easily reducing unit head, or damage drill rod thread, thus drilling rod is scrapped.This just needs unit head should have axial buffer function when driving drilling rod, impacts the damage that brings to alleviate.
The horizontal directional drilling machine that has is installed shock-absorbing spring and is solved this problem on the vice clamping device.This scheme has only solved the shock problem when changing drilling rod, and the shock problem that produces when creeping into work still exists.
The summary of the invention the purpose of this utility model provides a kind of rational in infrastructure, easy accessibility, has driving, the drilling rod of buffering double action drives buffer.
The purpose of this utility model is achieved in that this drilling rod drives buffer and comprises splined shaft, sliding axle, two buffer springs, spring base; Travelling gear is installed on the splined shaft and is bearing in the unit head casing by two bearings, sliding axle passes splined shaft and connects by spline, and a buffer spring respectively is installed at its two ends; Sliding axle one end carries out axial location with round nut and stop washer, and the other end very connects with brill.Travelling gear is passed to splined shaft to power, and splined shaft drives sliding axle and bores very work by splined; When axial impact force, sliding axle is in axial sliding with respect to splined shaft, absorbs impact energy by spring, reaches the buffering purpose.
Described sliding axle one end is the flange linkage section, and the other end is the section of being threaded, and the middle part is an external splines;
Described splined shaft two ends are for supporting shaft part, and the centre is an external splines, and inside is internal spline;
Advantage of the present utility model: simple in structure, easy to maintenance; Adopt mechanical device, reliable operation; Can effectively reduce impact in the rig work to the infringement of drill rod thread and unit head.
Be described further below in conjunction with drawings and Examples.
Description of drawings Fig. 1 is the utility model example structure sketch.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
1. round nuts among the figure; 2. stop washer; 3. spring base; 4. spring; 5. spring base; 6. oil sealing; 7. preceding casing; 8. bearing; 9. splined shaft; 9-1. supporting shaft part; 9-2. external splines; 9-3. internal spline; 10. gear; 11. sliding axle; 11-1. the section of being threaded; 11-2. external splines; 11-3. flange linkage section; 12. rear box; 13. axle sleeve; 14. spring base; 15. bolt; 16.O shape circle; 17. pin; 18. bore very.
The embodiment of specific embodiment present embodiment is as follows: the gear (10) of packing into earlier on the external splines (9-2) of splined shaft (9), after two sections supporting shaft parts (9-1) are respectively charged into bearing (8), be respectively charged into again in preceding casing (7) and the rear box (12), and the oil sealing of packing into (6); Sliding axle (11) flange linkage section (11-3) pocketed springs (4), spring base (14), and behind the dress axle sleeve (13), penetrate splined shaft (9) endoporus from a side, the internal spline (9-3) of splined shaft (9) and external splines (11-2) formation of sliding axle (11) are slidingly matched, opposite side refills upper spring seat (5), spring (4), the section of being threaded (11-1) of spring base (3) and sliding axle is by being threaded, and with stop washer (2), round nut (1) axial restraint; The flanged ends (11-3) of sliding axle (11) is endured (18) by bolt (15), pin (17) and brill and is connected, and sliding axle (11), brill very enclose (16) with O shape between (18) and seal, and lubricating cup (19) is installed on the inner spring seat (5).By above installation, finish present embodiment.
The course of work of the present utility model is: in the course of work, gear (10) is delivered to splined shaft (9) to moment of torsion, and passes to sliding axle (11) by spline, drives very (18) work of boring; When unit head advances, bore and endure the thrust that (18) are subjected to drilling rod, sliding axle (11) is slided to the left, the spring of right-hand member (4) by compression, the shaft shoulder up to sliding axle (11) contacts with spring base (14), and (18), sliding axle (11), spring base (14), splined shaft (9), bearing (8) affact on the preceding casing (7) of unit head thrust from boring very; Unit head returns when dragging, bore and endure the pulling force that (18) are subjected to drilling rod, the spring of left end (4) by compression, contact with spring base (5) up to spring base (3), (18), sliding axle (11), spring base (3) and spring base (5), splined shaft (9), bearing (8) pass on the unit head rear box (12) pulling force from boring very; In the course of the work or when changing drilling rod, unit head begins or stop motion, when producing impact force, impact force at first acts on the spring (4) by sliding axle (11), behind spring (4) vibration damping, just continue to pass on unit head or the drill rod thread, so just reduced infringement unit head and drill rod thread.So, the utility model has just been realized the purpose that drives and cushion.
