Detailed description of the invention
Utilize that telescope pole installation rate is slow, accident factor is many, labor intensity is large, two joint telescopic derricks are very heavy, easily burn rear thrust wheel, also greatly increase the height of center of mass of complete machine, travel not steady, the utility model designs the tractor hoist that band hydraulic pressure vertical one saves overall derrick.
Embodiment 1:
The present embodiment provides a kind of tractor hoist with monolithic derrick, as shown in Figure 1, comprise the frame 2 on crawler body 1 and crawler body 1, frame 2 is provided with fore-stock 3, after-poppet 8 and hydraulic pressure cube oil cylinder 7, fore-stock 3 and after-poppet 8 pop-up are placed with derrick 4, and expansion link and the derrick 4 of hydraulic pressure cube oil cylinder 7 are hinged, and described derrick 4 is a joint monolithic derrick, derrick 4 is hinged with after-poppet 8, and fore-stock 3 realizes fixing to holding derrick 4.
This structure of the present embodiment, because the derrick 4 on this tractor hoist is a joint monolithic derrick, so when this tractor hoist work, utilize hydraulic pressure cube oil cylinder 7 by derrick 4 jack-up, because derrick 4 and after-poppet 8 are hinged and support hold in the palm with fore-stock 3 and fix, so derrick 4 can leave fore-stock 3, by with after-poppet 8 tie point centered by do circular path and move, until contact to earth in one end of derrick 4, complete propping up of derrick 4, now can complete follow-up drifting operation.
Embodiment 2:
On the basis of embodiment 1, in the present embodiment, the high 0 ~ 500mm of height of the aspect ratio after-poppet 8 of fore-stock 3, a more accurate implementation result is the height height 220mm of the aspect ratio after-poppet 8 of fore-stock 3.
As everyone knows, the operating location of tractor hoist is all generally the area of landform more complicated, tractor hoist is when rushing for operating location, the landform of upward slope descending may being encountered, and derrick has overhead traveling crane, contacting to earth to prevent tractor hoist overhead traveling crane when descending, the height of fore-stock 3 arranges higher than the height of after-poppet 8 by the present embodiment, after derrick 4 fell, derrick 4 is in forward-lean state in the process of moving, and the overhead traveling crane be positioned at like this on derrick 4 is just not easy to contact to earth.
Embodiment 3:
In the present embodiment, fore-stock 3 to frame 2 front tilt 200 ~ 600mm, after-poppet 8 to frame 2 back sweep 100 ~ 500mm, a more accurate implementation result be fore-stock 3 to frame 2 front inclination 430mm, after-poppet 8 is to frame 2 back sweep 300mm.
This structure of the present embodiment has two effects, is first for producing derrick work inclination angle, is secondly the distance increasing two fulcrums when derrick fell.
If after-poppet 8 does not tilt, so in order to keep the stability of derrick 4 duty, derrick 4 must be made also to be vertical state, so just can to stablize, but very inconvenient time such way can make through downloading hanging articles, even cannot hang, in order to avoid the generation of this situation, the present embodiment by after-poppet 8 to frame 2 back sweep, time such derrick 4 is fixed can with after-poppet 8 against each other, form the angle of inclination of derrick 4, time drifting operation convenient.
On the other hand, the distance of two fulcrums is nearer, the object put thereon is more unstable, limiting case is two fulcrums and overlaps, it is least stable situation, in order to slow down the generation of this situation, the distance between needing two fulcrums is the bigger the better to a certain extent, and the present embodiment fore-stock 3 tilts to frame 2 front, after-poppet 8 all can increase distance between two fulcrums to frame 2 back sweep.
Embodiment 4:
Fore-stock 3 and after-poppet 8, on the basis of above-mentioned three embodiments, are all set to " ∧ " shape strut by the present embodiment, and " ∧ " shape strut top of fore-stock 3 is provided with the clip of fixing derrick 4.According to leg-of-mutton stability, this " ∧ " shape strut of the present embodiment is better as supporting framework stability, and top is provided with clip, and derrick 4 can be fixed, derrick 4 can not arbitrarily swing in the process of moving.
Further, the front vertical of the present embodiment below frame 2 is provided with straight support formula jack 5, and straight support formula jack 5 is positioned at immediately below after-poppet 8, to accept well workover load.
Embodiment 5:
On the basis of above-mentioned 4 embodiments, the after-poppet 8 in the present embodiment adopts the mode of movable bolt to be connected in frame 2, and the bottom of after-poppet 8 is fixed in frame 2 by movable bolt 6.
" ∧ " shape strut has two bottoms, be fixed in frame 2 respectively by movable bolt 6, movable bolt 6 can regulate the angle of inclination of after-poppet 8, and then the adjustment completed derrick work inclination angle, and movable bolt 6 can draw toward derrick by after-poppet 8, under preventing fortuitous event, derrick is towards the front overturning of tractor hoist, saves the guy wire at tractor hoist rear.
Further, in the present embodiment, hydraulic pressure cube oil cylinder 7 has two, is symmetricly set on the both sides of frame 2, and the other end of two hydraulic pressure cube oil cylinders 7 is connected to the same position of derrick 4.
In sum, the tractor hoist of this band monolithic derrick of the present utility model, can avoid all inconvenience that two joint telescopic derricks bring, cost is lower, and easy to use.
More than exemplifying is only illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, everyly all belongs within protection scope of the present invention with the same or analogous design of the utility model.
