Specific embodiment
It is right below according to specific embodiment and in conjunction with attached drawing to make the contents of the present invention be easier to be clearly understood The present invention makes further details of explanation.
A kind of high stability tubing derrick crane is present embodiments provided, as shown in Figure 1, including tower body 1, in tower body 1 upper end is provided with turntable 2, and the upper end of turntable 2 is provided with tower top 3.It is relatively set in the left and right sides of tower top 3 flat Weigh arm 4 and crane arm 5, is equipped with jack machinism on crane arm 5.Jack machinism includes skip 6, is equipped in skip 6 The first driving device 8 that spiral roller 7 and driving spiral roller 7 rotate, first driving device 8 can be rotating electric machine, on spiral roller 7 Be wound with draught line 9, one end of draught line 9 is fixed on spiral roller 7, the other end stretch out skip 6 after with pipe clamping Mechanism is fixedly connected.By the driving of first driving device 8, spiral roller 7 is driven forward or reverse, carry out unwrapping wire or take-up, from And clamping mechanism of tubular product is driven to decline or rise.In addition, being also rotatably equipped with idler wheel 19 in skip 6, idler wheel 19 is rolled It is mounted on crane arm 5, idler wheel 19 and third driving device are drivingly connected, and third driving device is also rotating electric machine, by the Three driving devices drive idler wheel 19 to rotate, and roll idler wheel 19 on crane arm 5, to drive skip 6 along crane arm 5 or so It is mobile.
Clamping mechanism of tubular product includes the positioning head 10 being fixedly connected with draught line 9, and two groups of folders are equipped on positioning head 10 Device is held, which includes being fixedly mounted on 10 the second driving device of lower end 17 of positioning head, and the second driving device 17 can be Hydraulic cylinder.Second driving device 17 is sequentially connected with a drive rod 16, by the driving of the second driving device 17, can drive transmission Bar 16 is gone up and down along the vertical direction.The lower end of drive rod 16 is provided with suspension hook 12.As shown in figure 3, suspension hook 12 include connection and First be oppositely arranged hangs pawl 14 and second and hangs pawl 15.First hang pawl 14 and second hang pawl 15 bending section be respectively hinged at connection First 13 left and right ends, first hang pawl 14 and second hang pawl 15 upper end extend to connector 13 upper end and with drive rod 16 Lower end is hinged.When drive rod 16 moves down, first, which hangs pawl 14, hangs pawl 15 with second and is located remotely from each other;When drive rod 16 rises, the One, which hangs pawl 14 and second, hangs the realization close to each other of pawl 15 closure.
Wherein, two groups of clamping devices are separately positioned on left end and the right end of positioning head 10, and two in two groups of clamping devices Suspension hook 12 is in same horizontal line, and two suspension hooks 12 can grip the different location of tubing.
As shown in figure 4, the side for hanging pawl 14 first offers notch 18, which hangs 14 side lower end of pawl by first Extend upwardly to the middle part of side.When the second driving device 17 driving drive rod 16 rises, first, which hangs pawl 14 and second, hangs pawl 15 is close to each other until closure.When drive rod 16 continues to rise, second, which hangs pawl 15, protrudes into the first notch 18 for hanging 14 side of pawl In, and continue to move to, make first to hang pawl 14 and hang pawl 15 with second and intersect, makes first to hang pawl 14 and second and hang gap between pawl 15 It further reduces.It is mounted on flexo cushion on the opposite side of pawl 15 in addition, hanging pawl 14 first and hanging with second, the flexibility Cushion can be used rubber and be made.
Two telescopic rods 20 are also fixedly installed in the upper end of positioning head 10, the upper end of telescopic rod 20 is fixedly mounted on lifting On case 6.Two telescopic rods 20 are located at the left and right side of draught line 9, and two telescopic rods 20 are located at same perpendicular It is interior.The telescopic rod 20 includes the body of rod that several sections mutually socket-connect, and the junction of the adjacent body of rod is provided with limiting device, can avoid bar Body falls off.
Specific works are described as follows: firstly, first driving device 8 drives spiral roller 7 to rotate, releasing draught line 9, tubing folder It holds mechanism and is slowly declined by gravity, until reaching at tubing, several pole bodies during decline in telescopic rod 20 are successively It stretches out.When suspension hook 12 reaches at tubing, the second driving device 17 drives drive rod 16 to decline, and makes first to hang pawl 14 and hangs with second Pawl 15 separates, and then clamping mechanism of tubular product continues to move down, and so that tubing is located at first and hangs pawl 14 and second and hang between pawl 15, and subsequent the Two driving devices 17 drive drive rod 16 rise, first hang pawl 14 with second hang pawl 15 it is adjacent to each other until be closed, make two to hang Hook 12 is clamped on tubing respectively, and subsequent first driving device 8 drives spiral roller 7, and clamping mechanism of tubular product is made to drive tubing Rise.Several pole bodies of telescopic rod 20 successively protrude into the adjacent body of rod in uphill process, and the position-limiting action of telescopic rod 20 makes The direction of positioning head 10 remains unchanged, to guarantee the direction of tubing, tubing is avoided to rotate and fall.It is leaned on when tubing is promoted to When the height of nearly skip 6, third driving device drives idler wheel 19 to rotate, and moves skip 6 along crane arm 5, to drive Tubing is mobile, cooperates the rotation of turntable 2 on tower body 1, tubing is migrated to suitable station, subsequent second driving device 17 is driven Dynamic drive rod 16 declines, and makes first to hang pawl 14 and second and hangs pawl 15 away from each other, falls tubing from suspension hook 12, realizes automatic Discharging.
In addition to the implementation, the present invention can also have other embodiments;It is all to use equivalent substitution or equivalent transformation shape At technical solution, fall within the scope of protection required by the present invention.
