Description
Technical field
The utility model relates to a kind of drilling rod carriage, particularly a kind of horizontal directional drilling machine drilling rod carriage.
Background technology
The drilling rod carriage is the vitals that horizontal directional drilling machine is lifted drilling rod.On big-and-middle-sized horizontal directional drilling machine,, in the use of drilling rod, brought a lot of difficulties to us because drilling rod itself is long, heavier.When drilling rod was installed, we can utilize truck-mounted crane that one end of drilling rod is placed on the vice, but because the action of gravity of drilling rod, the other end of drilling rod is difficult to be connected with unit head, and the constructor who needs us is with just hand steered; During dismounting drilling rod, after unit head and drilling rod are dismantled,,, all can cause damage to drilling cramp and drilling rod itself just drilling rod can drop on the drilling cramp upper surface if need not be hand steered live drilling rod.
The self-action drilling rod carrier structure that adapts to big-and-middle-sized directional drilling machine at present both at home and abroad mainly is installed in the drilling cramp upper surface.This drilling rod carriage that is installed in the drilling cramp upper surface, be placed between vice and the unit head, because the thickness of itself, making unit head contact distance with the minimum of vice increases, thereby require us to increase the length of unit head drill collar, like this unit head drilling rod in the continued access vice easily.The rotation of unit head do not have absolute with one heart, the increase of drill collar length must cause the error of rotating eccentricity to increase, and so also needs a covering device to guarantee that unit head keeps relative concentricity in rotary course, increased design cost.
The utility model content
The purpose of this utility model is to provide a kind of: easy accessibility; In that the time spent might as well not hinder the horizontal directional drilling machine drilling rod carriage of miscellaneous part operate as normal.
Implementation of the present utility model is: this structure comprises axle sleeve, fixed axis one, pressing plate, oil cylinder, bearing pin, bearing, steel pipe, swivel mount, fixed axis two, back-up ring, bearing and roller, end at oil cylinder is connected with fixed axis one, on the fixed axis two of oil cylinder two sides, axle sleeve is arranged, the other end of oil cylinder is connected on the swivel mount by bearing pin, swivel mount is a bending, flex point in bending has fixed axis two, fixed axis two is connected with swivel mount by bearing, on the fixed axis in the middle of the swivel mount, steel pipe is arranged, the other end at swivel mount has bearing pin, two ends of bearing pin have back-up ring, and bearing pin is connected on the swivel mount by bearing, on the bearing pin in the middle of the swivel mount roller are arranged.
Described roller two is pluckings, and is middle thin, becomes circular-arc.
Beneficial effect owing to adopted such scheme, has two groups of holes respectively on swivel mount, fixed axis one and fixed axis dual-purpose pressing plate can be fixed on the swivel mount.One end of oil cylinder is installed on the fixed axis one, and the other end is installed on the swivel mount; Swivel mount is a bending structure, and a wherein end at two ends is connected with swivel mount with pressing plate with fixed axis two in addition, and the other end is equipped with roller; When the oil cylinder piston bar stretches out or withdraws, the end that swivel mount connects oil cylinder is forced to its motion, and its forms of motion is around fixed axis one rotation, thereby the other end of swivel mount is also around fixed axis two rotations, make roller can contact or break away from drilling rod, promptly realized drilling rod carriage function.All there is axle sleeve at the two ends of oil cylinder installation end, and the gap between them is very little, make the oil cylinder can be towards the both sides play; Between swivel mount and the drilling cramp bearing is installed, it can be rotated flexibly; Between roller and the swivel mount bearing is installed, it can be rotated flexibly.Easy accessibility; Might as well hinder the miscellaneous part operate as normal in time spent not, reach the purpose of this utility model.
Advantage: one, saved a large amount of labours; Two, this structure can fall within drilling cramp inside in the normal walking process of unit head; Three, can realize the function of lifting of drilling rod automatically, make things convenient for the dismounting of drilling rod.
Description of drawings
Fig. 1 is a fractionation structure chart of the present utility model.
Fig. 2 is an assembly structure figure of the present utility model.
Among the figure, 1, axle sleeve; 2, fixed axis one; 3, pressing plate; 4, oil cylinder; 5, bearing pin; 6, bearing; 7, steel pipe; 8, swivel mount; 9, fixed axis two; 10, back-up ring; 11, bearing; 12, roller
The specific embodiment
Embodiment 1: this structure comprises axle sleeve 1, fixed axis 1, pressing plate 3, oil cylinder 4, bearing pin 5, bearing 6, steel pipe 7, swivel mount 8, fixed axis 29, back-up ring 10, bearing 11 and roller 12, end at oil cylinder 4 is connected with fixed axis 1, on the fixed axis 29 of oil cylinder 4 two sides, axle sleeve 1 is arranged, the other end of oil cylinder 4 is connected on the swivel mount 8 by bearing pin 5, swivel mount 8 is a bending, flex point in bending has fixed axis 29, fixed axis 29 is connected with swivel mount 8 by bearing 7, on the fixed axis 29 in the middle of the swivel mount 8, steel pipe 7 is arranged, the other end at swivel mount 8 has bearing pin 5, two ends of bearing pin 5 have back-up ring 10, bearing pin 5 is connected on the swivel mount 8 by bearing 6, on the bearing pin 5 in the middle of the swivel mount 8 roller 12 is arranged.
Described roller two is pluckings, and is middle thin, becomes circular-arc.
Hydraulic oil flow makes the piston rod withdrawal through oil cylinder, owing to the one end is fixed, so the other end will move along the piston rod retracted orientation.This motor reaction to swivel mount then is: an end of swivel mount is fixed, and connects the oil cylinder end and does counterclockwise motion around swivel mount, and the other end is also done counterclockwise motion around swivel mount, makes roller rise, and holds drilling rod.The two ends of oil cylinder are installed axle sleeve and are limited oil cylinder towards the both sides play; On the fixed axis two that swivel mount is connected with drilling cramp bearing is installed, swivel mount can be rotated flexibly; Bearing and back-up ring are installed between roller and the swivel mount, can be made roller rotate flexibly, prevent axial float respectively; The external surface of roller is circular-arc, can hold drilling rod easily.When unit head moves reciprocatingly on drilling cramp, to interfere in order to prevent unit head and drilling rod carriage, the piston rod of oil cylinder stretches out, and swivel mount is done clockwise rotation around fixed axis two, is that the drilling rod carriage falls within the drilling rod body.The installation site of fixed axis and the stroke of oil cylinder, locating distance are wanted accurately, and the realization that makes each function all is that oil cylinder is when reaching maximum or minimum stroke, to make things convenient for tractor driver's operation.
