Technical field
The present invention relates to a kind of truck-mounted drilling rig and change lever apparatus, be applicable to the upper and lower drilling rod of truck-mounted drilling rig and coordinate unit head to complete drilling rod handling.
Background technology
Truck-mounted drilling rig as a kind of automaticity more much higher technique wellbore construction equipment, have rate of penetration fast, be applicable to multiple drilling process, the advantage such as job stability is strong, repair and maintenance is convenient, simple to operate, less important work is convenient and strength-saving, dismounting and convenient transportation.Truck-mounted drilling rig is widely used in the drilling constructions such as large diameter water well, coal bed gas extraction well, Oil/gas Well, and be a mainstream development trend of rig from now on, the equipment supporting with it is also in quick renewal.Drilling work is the important step affecting drilling operation efficiency.At present, most engineering driller adopts and is first elevated drilling rod by hoist, drilling rod after slips clamping, by hoisting system with manually load and unload drilling rod task.For large-scale ground truck-mounted drilling rig, add, unload the needs that drilling rod operation must consider to remove the drilling tool such as drilling rod and sleeve pipe simultaneously, because drilling rod is longer and quality is larger, carry and change bar work all comparatively difficulty, labor strength is large, and efficiency is low, and easily causes potential safety hazard.What therefore urgent need design was supporting with it changes lever apparatus.
Summary of the invention
The object of the invention is to for the problems referred to above, provide a kind of truck-mounted drilling rig to change lever apparatus, overcome the deficiency of drilling rod lower work platform, reduce labor strength, increase work efficiency.
For achieving the above object, the present invention adopts following technical scheme:
A kind of truck-mounted drilling rig changes lever apparatus, comprises fuselage 1, translation supporting leg 2, firm supporting leg 3, drilling rod feeding body 4, feeding body mount pad 5, clamping device 6, fuselage angle modulation oil cylinder 7, lifting gear 8, adjustment oil cylinder 9 and accessory structure.Wherein, described fuselage 1 is installed with translation supporting leg 2 and two to firm supporting leg 3, drilling rod feeding body 4 by feeding body rear axle and feeding body mount pad 5 hinged, clamping device 6 is fixedly installed in drilling rod feeding body 4, lifting gear 8 is fixedly installed in fuselage 1 side, adjustment oil cylinder 9 two ends be separately fixed on fuselage 1 and lifting gear 8, fuselage angle modulation oil cylinder 7 respectively with drilling rod feeding body 4 and fuselage 1 hinged, the tilt angle of controlling drilling bar feeding body 4.
Wherein, the erection support of three groups of lifting gears 8 is respectively arranged in fuselage 1 two sides, selects different erection supports can change the position of lifting gear 8 in fuselage 1 side, and then the loading meeting different length drilling rod is changed.
Wherein, adjustment oil cylinder 9 stretches, and change the heeling condition of lifting gear 8, when tilting to fuselage 1, the drilling rod in drilling rod supporting plate is automatically scrolling in drilling rod pallet 12, and pallet overturning oil cylinder 13 stretches, and drilling rod pallet overturns 45 °, enters next step operation; When lifting gear 8 is to fuselage 1 reversed dip, the drilling rod that drilling rod pallet 12 rolls out can be rolled in the drilling rod supporting plate 24 of lifting gear 8 along inclined-plane, enters next step operation.
Wherein, the drilling rod pallet 12 on drilling rod feeding body 4 through pallet feed oil cylinder 14 act on advance, drilling rod enters clamping device 6, after drill-rod clamping push rod oil cylinder 15 act under pushed forward, complete with drill power head and dock.
The operating principle that truck-mounted drilling rig of the present invention changes lever apparatus is: lifting gear 8 lift cylinder 22 piston rod stretches out or retracts and can realize drilling rod supporting plate 24 through wire rope 23 and rise or fall, thus realize ground drilling rod being promoted or the drilling rod from drilling rod feeding body 4 being dropped to ground, the flexible drilling rod fork 26 that can realize of overturning oil cylinder 25 piston rod rotates, namely realize drilling rod supporting plate 24 to rotate, in upper and lower drilling rod process, drilling rod supporting plate 24 rotates 90 ° and can realize drilling rod and conveniently roll into or roll out drilling rod pallet 12; Drilling rod feeding body 4 supporting plate feeds oil cylinder 14 and stretches out or retract and the drilling rod in drilling rod pallet 12 can be moved to clamping device 6 or be shifted out from clamping device 6 by the drilling rod dismantled from unit head 10.Push rod oil cylinder 15 stretches out or retracts and clamping device 6 can be moved forward or backward, thus realizes the position control of drilling rod in drilling rod pallet 12.The effect of stretching out through support arm 20 of clamping oil cylinder 19 piston rod can realize slips 21 and clamp drilling rod, and piston rod is retracted and unclamped drilling rod.
Beneficial effect
Compared with changing lever apparatus with existing truck-mounted drilling rig, it is upper and lower that the lifting gear 8 that truck-mounted drilling rig of the present invention changes lever apparatus adopts bar linkage structure to realize drilling rod, structure is simple, easy to operate, work plane is low, adds lever apparatus volume little, lightweight, and field worker labour intensity is low, automaticity is high, improves operating efficiency.
