It is hinged to frame stage casing end, an ear mount of leading truck stage casing end is by short extending cylinder and another ear of leading truck base segment
Seat is hinged；On leading truck base segment, the axis hole position of neighbouring stage casing rotary shaft is provided with a pin hole, and leading truck stage casing end is in neighbour
The axis hole position of nearly stage casing rotary shaft is provided with two corresponding pin holes；
End of the leading truck stage casing front end by leading portion rotary shaft with leading truck leading portion is hinged, the middle part ear of leading truck leading portion
Seat is hinged with long extending cylinder piston rod end by long cylinder rotary shaft, and the cylinder body bottom of long extending cylinder is slided by sliding pin
It is sleeved in the chute of sliding chute seat, sliding chute seat is vertically fixed on the interior side elevation of continuous tube injection head main body.
Folded in three formula continuous tube injection head leading truck of the present utility model, is further characterized in that：
Short extending cylinder and long extending cylinder are connected with hydraulic control.
Long extending cylinder is as needed using the hydraulic cylinder of common Long travel, or adopts multistage hydraulic cylinder.
The beneficial effects of the utility model are that leading truck can be realized shrinking completely, greatly reduce the whole of injection head
Body occupies space so that vehicle-mounted continuous-tube injection head device is easily arranged on car body, is also convenient in transport.

Specific embodiment
With reference to the accompanying drawings and detailed description the utility model is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, structure of the present utility model is that the upper surface for being included in continuous tube injection head main body 12 is consolidated
Dingan County is equipped with leading truck base segment 1, and leading truck base segment 1 is hinged with 2 end of leading truck stage casing upwardly through stage casing rotary shaft 8, is oriented to
Another ear mount of one ear mount of 2 end of frame stage casing by short extending cylinder 4 with leading truck base segment 1 is hinged, short extending cylinder 4
Extension and contraction control leading truck stage casing 2 rotate around stage casing rotary shaft 8；The axis hole position of neighbouring stage casing rotary shaft 8 on leading truck base segment 1
A pin hole is provided with, 2 end of leading truck stage casing is provided with two corresponding latches in the axis hole position of neighbouring stage casing rotary shaft 8
Hole, to insert latch 9 during 2 raising of leading truck stage casing, being directed to frame stage casing 2 and leading truck base segment 1 carries out grafting and determines
Position；
End of 2 front end of leading truck stage casing by leading portion rotary shaft 10 with leading truck leading portion 3 is hinged, leading truck leading portion 3
Middle part ear mount is hinged with 5 piston rod end of long extending cylinder by long cylinder rotary shaft 11, and the cylinder body bottom of long extending cylinder 5 passes through
Sliding pin 7 slides and is sleeved in the chute of sliding chute seat 6, and sliding chute seat 6 is vertically fixed on the interior edge-on of continuous tube injection head main body 12
Face；
Short extending cylinder 4 and long extending cylinder 5 are connected with hydraulic control.
