Description
Technical field
The utility model relates to a kind of rig main arm structure, particularly relates to a kind of Collapsible structure of rig principal arm.
Background technology
the principal arm of 150 rigs supports the highest station of drill bench is in the market 4.2 meters, during to carry out drilling construction to the station of more than 4 meters height, more exchange device or proping carry out the drilling construction of high station to need, more exchange device can increase the cost of production input of enterprise, although the mode of proping is feasible, but because be work high above the ground, there is potential safety hazard, and waste time and energy.
Utility model content
Technical problem to be solved in the utility model there is provided a kind of rig main arm telescoping structure, by lengthening the main telescopic arm structure of rig, realizes rig height station drilling construction.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of rig main arm telescoping structure, first principal arm assembly is provided with the second principal arm assembly, oil cylinder is provided with in second principal arm assembly, the free bearing pinned connection on the second principal arm assembly termination and first principal arm assembly one end is stretched out in oil cylinder one end, the oil cylinder other end and the second principal arm assembly side pinned connection, second principal arm component bottom plane and the first principal arm assembly end face are equipped with track, and track two ends are respectively equipped with the first slide block and the second slide block.
The first described slide block is arranged on second principal arm assembly one end, the second described slide block is arranged on the other end away from the second slide block on the first principal arm assembly, first slide block can slide along the track of end face on the first principal arm assembly, and the second slide block can slide along the track of the second principal arm component bottom plane.
Described track adopts cold drawn band steel.
Two rig principal arms are connected with slide block by track by a kind of rig main arm telescoping structure that the utility model provides, and extend and shorten rig principal arm under the effect of oil cylinder, realize the lifting of rig principal arm height by extending rig principal arm.The utility model structure is simple, easy to operate, has saved cost of production, has improve operating efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, utility model is described further:
Fig. 1 is structural front view of the present utility model.
Fig. 2 is structure top view of the present utility model.
Fig. 3 is the A-A cut-away view of Fig. 1.
Fig. 4 is the B-B cut-away view of Fig. 2.
In Fig. 1-4: free bearing 1, oil cylinder 2, the second principal arm assembly 3, first principal arm assembly 4, oil cylinder bearing pin 5, first slide block 6, second slide block 6a, track 7.
Detailed description of the invention
As shown in figs. 1-4, a kind of rig main arm telescoping structure, first principal arm assembly 4 is provided with the second principal arm assembly 3, oil cylinder 2 is provided with in second principal arm assembly 3, free bearing 1 pinned connection on the second principal arm assembly 3 termination and first principal arm assembly 4 one end is stretched out in oil cylinder 2 one end, oil cylinder 2 other end and the second principal arm assembly 3 side pinned connection, the second principal arm assembly 3 bottom surface and the first principal arm assembly 4 end face are equipped with track 7, and track 7 two ends are respectively equipped with the first slide block 6 and the second slide block 6a.
The first described slide block 6 is arranged on second principal arm assembly 3 one end, the second described slide block 6a is arranged on the other end away from the second slide block 6a on the first principal arm assembly 3, first slide block 6 can slide along the track 7 of end face on the first principal arm assembly 4, and the second slide block 6a can slide along the track 7 of the second principal arm assembly 3 bottom surface.
By a little structure, slided along track 7 respectively by the first slide block 6 and the second slide block 6a, the elongation relative with the first principal arm assembly 4 of the second principal arm assembly 3 and shortening can be realized, the drilling construction of rig height station can be realized when two principal arms are stretched to the longest position.Oil cylinder 2 other end and the second principal arm assembly 3 side pinned connection play spacing effect, prevent two principal arms from pulling out.
Described track 7 adopts cold drawn band steel.The stability of rig work can be improved.
When using rig to carry out the drilling construction of high station, rig principal arm is under the effect of oil cylinder 2, first slide block 6 can slide along the track 7 of end face on the first principal arm assembly 4, second slide block 6a can slide along the track 7 of the second principal arm assembly 3 bottom surface, realize the first principal arm assembly 4 and the second principal arm assembly 3 stretches mutually, when the second principal arm assembly 3 is stretched to the position of oil cylinder bearing pin 5, the length of rig principal arm reaches the longest, when rig principal arm moves upward, can realize the drilling construction of rig height station, maximum height can reach 7.5 meters.
