Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
Reference picture 1, Fig. 2, Fig. 5, structure of the present utility model are, including derrick assembly 1 and travelling assembly 2, derrick assembly 1
It is steel-frame structure, one group of slide rail 3 is respectively fixed with four columns of the surrounding of derrick assembly 1, the sliding for 2 four jiaos of the assembly that moves about
Component 11 is corresponding to be sleeved in each slide rail 3, travelling assembly 2 is realized in derrick assembly 1 and is slided up and down；In derrick assembly 1
Lower end is connected by bearing pin with the cylinder body base of oil cylinder 7；
Reference picture 3, Fig. 4, the structure of travelling assembly 2 is, including floating frame 4, is separately installed with the upper and lower ends of floating frame 4
Top sheave 9 and lower sheave 10, sliding assembly 11 is respectively arranged with the upper and lower side both sides of floating frame 4, sliding assembly 11 is arranged to sliding
Block or pulley form, it is engaged with the slide rail 3 set on 1 four columns of derrick assembly；It is wound between top sheave 9 and lower sheave 10
Steel wire rope 5, the active segment of steel wire rope 5 are fixedly connected with hoisting mechanism 8, after steel wire rope 5 is around top sheave 9 and lower sheave 10, steel
The two ends of cord 5 are connected with steel wire rope fixing mechanism 6, and steel wire rope fixing mechanism 6 is fixed on well (by bearing pin or welding manner)
On frame assembly 1；
The upper end of floating frame 4 is hinged by the piston rod lug of bearing pin and oil cylinder 7, and the piston rod of oil cylinder 7 is upward through travelling
Grid beam inside frame 4, makes the piston rod retractable of oil cylinder 7, at the same when vertical direction moves with travelling assembly 2 into one
Straight line.
Operation principle of the present utility model is,
See Fig. 1, the initial position of hoisting mechanism 8 is in the bottom of derrick assembly 1, when the piston rod of oil cylinder 7 extends, in floating frame 4
The dynamic travelling assembly 2 of shipper pole moves up, because steel wire rope 5 is fixed at steel wire rope fixing mechanism 6 with derrick assembly 1, so steel wire rope 5
Hoisting mechanism 8 can only be pulled to move up, play a part of carrying drilling rod, now move on to highest order on hoisting mechanism 8, see Fig. 2.
Drive floating frame 4 to move down the travelling assembly 2 of pulling when the piston rod of oil cylinder 7 shortens to move down, now steel wire rope 5 pulls again
Hoisting mechanism 8 moves down, and plays a part of pressurizeing to drilling rod.
Because the top sheave 9 in the assembly 2 that moves about and lower sheave 10 are all movable pulley, when travelling assembly 2 moves up and down single times
Apart from when, top sheave 9 and lower sheave 10 are used as movable pulley, and steel wire rope 5 drives lifting system to move double distance, so elevator
The stroke of structure will be twice of oil cylinder stroke.
Device of the present utility model, hook are carried and undertaken by the oil cylinder 7 being arranged in derrick, and hook is carried by the pulley in floating frame
Oil cylinder 7 is delivered to, the hoisting mechanisms such as top drive can be driven to move up and down when being slid up and down in derrick；Meanwhile the floating frame can be real
Existing operational hydraulic cylinder stretch one stroke of unit when, the distance that twice of hoisting mechanism motor unit.
