Abstract
The utility model relates to a hydraulic mechanism, in particular to a hydraulic moving mechanism for rear excavators. The mechanism comprises a base and a moving frame arranged on the base, wherein a track for the sliding of the moving frame and a hydraulic moving mechanism are mounted on the base, the hydraulic moving mechanism includes an oil cylinder arranged on the base and a gear arranged on the oil cylinder and provided with a gear shaft, and a transmission gear rack meshed with the gear is mounted on the moving frame. The utility model has the benefits that the mechanism can not only reach the maximum stroke within the minimum moving space, but also improve the work efficiency.
Description
Technical field
The utility model relates to a kind of hydraulic mechanism, particularly a kind of excavator hydraulic pressure travel mechanism afterwards.
Background technology
General the moving of excavating the movable stand of facility behind the packaged type is by big swing arm, little swing arm, the move mode of the incompatible realization lateral adjustment of the action group of bucket position comparatively bothers, and be subjected to the restriction of environment space condition, when horizontal space is not enough, just can't carry out the lateral position adjustment to movable stand with this mode.Inconvenience when solving this operation, my company's development and Design go out a kind of controlled travel mechanism that utilizes hydraulic power to drive, and realize the omnidistance hydraulic-driven that the position of movable stand in its mobile range adjusted.
The utility model content
At the problems referred to above, the purpose of this utility model provides a kind of conveniently moving, can enlarge the back excavator hydraulic pressure travel mechanism of stroke.
The realization the technical solution of the utility model is as follows:
Back excavator hydraulic pressure travel mechanism, comprise pedestal and the movable stand that is arranged on the pedestal, pedestal is provided with the track that slides for movable stand, described pedestal is provided with hydraulic pressure travel mechanism, this hydraulic pressure travel mechanism comprises the oil cylinder that is arranged on the pedestal and is arranged on the gear that has gear shaft on the oil cylinder that described movable stand is provided with the travelling gear bar that is meshed with described gear.
Further, described oil cylinder comprises piston rod that is arranged on the pedestal and the cylinder barrel that matches with piston rod, described gear is arranged on the cylinder barrel, the gear shaft that matches with gear is fixedly installed on the cylinder barrel, gear is being installed on the gear shaft, and gear is around the gear shaft rotation and along with cylinder barrel moves around like this.
Further, described oil cylinder is two-way constant speed oil cylinder, when oil cylinder driven gear driving movable stand is moved to the left or moves right, can both make movable stand with identical speed and mobile stably like this.
Further, also be provided with navigation gear bar on the described pedestal, navigation gear bar is meshed with gear, can guarantee that like this movable stand can move along navigation gear bar when mobile, and the travelling gear bar all is meshed with gear with navigation gear bar, and navigation gear bar and travelling gear bar are separately positioned on the both sides of gear, and the shift motion of movable stand is the twice of cylinder tube shift motion like this, so, in the limited travel of oil cylinder, can realize the whole process of movable stand is driven.
Further, described navigation gear bar is fixedly installed on the crossbeam of pedestal, and the two ends of described piston rod are fixedly installed on the support of pedestal, and the cylinder barrel driven gear drives the side shifting of movable stand at pedestal like this.
The beneficial effects of the utility model are, adopt such scheme, compared with prior art, when horizontal space is not enough, movable stand can also carry out the lateral position adjustment, and the translational speed of movable stand in moving track be the twice of cylinder barrel translational speed, so not only can make movable stand in minimum mobile space, reach maximum stroke, also improved operating efficiency.
