Abstract
A dedicated chassis for a rotary drilling rig comprises a telescopic crawler travelling mechanism, a swing mechanism, and a swing platform, wherein a sliding platform is arranged on the swing platform; a sliding rack is connected to the sliding platform in a sliding manner, and is connected with the piston rod end of a pushing oil cylinder; the other end of the pushing oil cylinder is fixed on the swing platform; and the sliding rack is connected with the operation device of the rotary drilling rig through a connecting pin shaft, and can slide on the sliding platform linearly. The dedicated chassis has the advantages that the integral rigidity is good; the drilling perpendicularity of a drilling mast is guaranteed; the position of a pile hole can be aligned fast and accurately without moving the crawler of the chassis for the rotary drilling rig; and the stability of the operation device of the rotary drilling rig during swinging or drilling is high. Through the adoption of the dedicated chassis, the time for aligning a drill bit of the rotary drilling rig to the position of the pile hole is greatly shortened; and the precision of aligning the drill bit of the rotary drilling rig to the position of the pile hole is guaranteed.
Description
Technical field
The utility model relates to a kind of assembly of rotary drilling rig, particularly relates to a kind of rotary drilling rig chassis special.
Background technology
The rotary drilling rig chassis of prior art; Basically adopted the form of structure of excavator; Only change the crawler body that to expand into can expand commentaries on classics crawler body (H type adjustable crawler walking mechanism); The connected mode of revolving dial on the crawler body and rotary drilling rig equipment does not change, and still is two hinge connected modes.The rotary drilling rig on the two hinge connected mode chassis of general using adopts parallelogram to add little three-legged structure.This kind structure, the adjustment centre of gyration is comparatively convenient with stake hole centre distance, and the verticality of boring mast in the adjustment process is unaffected, but the rigidity of vertical and horizontal is relatively poor; Operation of Rotary Pile Drill and carrying when boring mast rock severe especially, poor stability.Also have a kind of rotary drilling rig that utilizes above-mentioned pair of hinge connected mode chassis, adopt big triangular structure form, the rigidity of this kind form of structure rotary drilling rig vertical and horizontal is better, good stability; But adopt the distance adjustment difficulty of the Operation of Rotary Pile Drill center of this big triangular structure form to stake center, hole, some big triangular structure form rotary drilling rig also influences the verticality of boring mast during adjustment; Some big triangular structure form also though do not influence the verticality of boring mast during adjustment, needs to move crawler belt, causes the adjustment precision not enough, expends a lot of non-cutting times.
The utility model content
The purpose of the utility model is to provide a kind of integral rigidity good, need not move crawler body can be fast accurately the adjustment centre of gyration and stake hole centre distance, and do not influence the rotary drilling rig chassis special that bores the mast verticality during adjustment.
The purpose of the utility model can realize.The rotary drilling rig chassis special that the utility model provides comprises slew gear and the revolving dial
that is provided with on adjustable crawler walking mechanism and the adjustable crawler walking mechanism.The rotary drilling rig chassis special of the utility model is characterised in that: said revolving dial is provided with sliding platform; Travelling carriage is slidingly connected on the said sliding platform; Said travelling carriage is connected with the tailpiece of the piston rod that promotes oil cylinder; The said promotion oil cylinder other end is fixed on the said revolving dial, and said travelling carriage is connected with the equipment of rotary drilling rig through connecting bearing pin.
The rotary drilling rig chassis special of the utility model, wherein said travelling carriage have a straight-line trajectory on said sliding platform.
Any adjustment that the utility model rotary drilling rig chassis special has been realized the relative Operation of Rotary Pile Drill centre distance of the big triangular structure form equipment of rotary drilling rig promptly realizes the adjustment function of align piles hole site.It is good that integral rigidity is compared on the utility model rotary drilling rig chassis special and the rotary drilling rig chassis of existing big triangular structure form; It is constant that the contraposition adjustment time can guarantee to bore the verticality of mast boring; Do not moving under the situation of rotary drilling rig chassis crawler belt; Can align a hole site fast and accurately, good stability in triangular structure form equipment fast rotation or when creeping into.
Be described further below in conjunction with the rotary drilling rig chassis special of accompanying drawing the utility model.
Description of drawings
Fig. 1 is the utility model rotary drilling rig chassis special master TV structure sketch map.
Fig. 2 is the utility model rotary drilling rig chassis special plan structure sketch map.
Fig. 3 moves forward and backward the adjustment process sketch map for the utility model rotary drilling rig chassis special travelling carriage.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, the utility model digs the rig chassis special and prior art is improved is achieved.The utility model digs the rig chassis special and comprises the slew gear 4 and revolving dial 2 that is provided with on H type adjustable crawler walking mechanism 1 and the H type adjustable crawler walking mechanism 1, also includes and promotes oil cylinder 3, travelling carriage 5, connects bearing pin 6, sliding platform 7.The revolving dial 2 of the rotary drilling rig chassis special of the utility model is provided with sliding platform 7.Travelling carriage 5 is slidingly connected on the sliding platform 7.Travelling carriage 5 is connected with the tailpiece of the piston rod that promotes oil cylinder 3, promotes oil cylinder 3 other ends and is fixed on the revolving dial 2.The big triangular structure form equipment of rotary drilling rig is connected on the travelling carriage 5 through connecting bearing pin 6.Travelling carriage 5 has a straight-line trajectory on sliding platform 7.Travelling carriage 5 can slide front and back on sliding platform 7 through promoting stretching of oil cylinder 3, realizes travelling carriage 7 and the big triangular structure form equipment of rotary drilling rig moving forward and backward along sliding platform 7.
The utility model has greatly reduced the time of drill bit stake hole site, traditional big triangular structure form rotary drilling rig chassis, and has guaranteed the precision of stake hole site.
The utility model digs the rig chassis special and had both kept through slew gear 4 the big triangular structure form equipment of rotary drilling rig being rotated on revolving dial 2; Realized again through travelling carriage 2 big triangular structure form equipment straight line on sliding platform 7 of rotary drilling rig being moved, what make that the drill bit of the big triangular structure form equipment of rotary drilling rig can be not only fast but also accurate aligns a hole site in 360 ° of working face scopes.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
