Description
Technical field
The present invention relates to a kind of construction machinery and equipment, particularly relate to a kind of can be in order to the crawler belt luffing device of adjustment rig center of gravity.
Background technology
At present, the crawler type rotary drilling rig is one of major product of construction machinery industry, and the effect of track unit in crawler type rotary drilling rig complete machine is heavy is: realize driving functions and the weight that supports complete machine.
But; Dig in the operation process revolving, because the revolution inertia of the pivoting part of rotation digging machine and the tilting moment of complete machine increase significantly, thereby the Spiral digging machine structure receives great resistance; Complete machine cause crank, very easily produce " nodding " phenomenon in the process of walking or roll-over accident take place.
Therefore, to rotary drilling rig the phenomenon of crank very easily takes place when the operation, at present, mostly technical personnel is through changing the position of both sides crawler belt in the industry, thereby regulates machine gravity.But; Because existing crawler type rotary drilling rig in the processing and manufacturing process, is fixed at the left and right sides track frame of car load support both sides for device, so can't realize the adjusting of center of gravity in the course of the work; When finding crank or special road surface situation when running into operation; The relative position that can't in time change crawler belt is especially realized the adjusting of center of gravity, and then can cause certain loss to rotary drilling rig, has also increased operator's labour intensity and work danger coefficient simultaneously.
Summary of the invention
Based on the existing in prior technology problem, main purpose of the present invention is to provide a kind of and changes the digging machine center of gravity, and operation is stable, and the rotary drilling rig crawler belt luffing device of safety of operation.
To achieve these goals, rotary drilling rig crawler belt luffing device according to the invention adopts following technical scheme:
Said rotary drilling rig crawler belt luffing device comprises vehicle frame, the first luffing support, the second luffing support, left track frame, right-hand track chiain frame and the amplitude oil cylinder that is installed in vehicle frame; Wherein, The said first luffing support and the second luffing support are for being installed in the two ends of vehicle frame respectively; Said left track frame and right-hand track chiain frame are arranged in the both sides of vehicle frame respectively; And left track frame is positioned at an end place of the first luffing support and the second luffing support, and right-hand track chiain then is positioned at the other end place of the first luffing support and the second luffing support, and between left track frame and the right-hand track chiain frame for to be movably connected through amplitude oil cylinder.
Further, all be equiped with the leg of a plurality of support usefulness on the said first luffing support and the second luffing support.
Further, the quantity of said amplitude oil cylinder is 2.
Further, said leg quantity is 2.
Rotary drilling rig crawler belt luffing device according to the invention can be according to the actual demand of field operation; Under the supporting role of leg and through the slip of amplitude oil cylinder, adjust the center of gravity of rotary drilling rig; Assurance has been played in stability and safety when the operation to rotary drilling rig; And apparatus structure is simple, and processing ease has practical value.
Description of drawings
Fig. 1 is the structured flowchart of rotary drilling rig crawler belt luffing device according to the invention.
The specific embodiment
Come rotary drilling rig crawler belt luffing device according to the invention is done further to specify below in conjunction with accompanying drawing and specific embodiment.
Rotary drilling rig crawler belt luffing device according to the invention can change the machine gravity of rotary drilling rig through the relative position that changes crawler belt.
Shown in Fig. 1, this luffing device comprises vehicle frame 10, the first luffing support 11, the second luffing support 12, left track frame 13, right-hand track chiain frame 14 and amplitude oil cylinder 15.
The said first luffing support 11 and the second luffing support 12 are for being installed in the two ends of vehicle frame 10 respectively; The front and back position place of ascending the throne and being located at vehicle frame 10; On this first luffing support 11 and the second luffing support 12, be equiped with passive leg 101 respectively, when practical application, leg 101 numbers on each luffing support can be 2; Thereby, fully supports machine gravity rotary drilling rig when being adjusted to reach; Promptly when the adjustment machine gravity, 101 pairs of complete machines of those said legs support, so that amplitude oil cylinder 15 is slided and changed the distance between left track frame 13 and the right-hand track chiain frame 14.
Said left track frame 13 is transversely movable track frame with right-hand track chiain frame 14 and is arranged in the both sides of vehicle frame 10 respectively; Wherein, Said left track frame 13 is for being positioned at an end place of the first luffing support 11 and the second luffing support 12; Said right-hand track chiain 14 then is positioned at the other end place of the first luffing support 11 and the second luffing support 12, and between left track frame 13 and the right-hand track chiain frame 14 for to be movably connected through amplitude oil cylinder 15.
Said amplitude oil cylinder 15 is for being installed in vehicle frame 10; And when practical application; This amplitude oil cylinder 15 realizes adjusting the distance between left track frame 13 and the right-hand track chiain frame 14 for adopting 2; Wherein, these said 2 amplitude oil cylinder 15 are for being installed in the two ends of vehicle frame 10 and between the first luffing support 11 and the second luffing support 12.
During operation; When the crawler type rotary drilling rig meets obstructions and machine gravity when unstable; The operator just can the actuating unit (not shown) through rig drives 101 of the legs that be positioned on the first luffing support 11 and the second luffing support 12 and gets up rig is supported and impels amplitude oil cylinder 15 slips; Slip through this amplitude oil cylinder 15 and then change the distance between left track frame 13 and the right-hand track chiain frame 14; Thereby the machine gravity of adjustment rig has finally guaranteed the stability and the safety of rig operation.
The above is merely the preferred embodiments of the present invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification sheets of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
