Abstract
The utility model provides a small walking vehicle which can realize a higher headroom and a lower operational height. An integrated small vehicle frame that is a first grade small vehicle frame added outside the original small vehicle that is a secondary grade small vehicle. The first grade small vehicle frame is connected with the secondary grade small vehicle through a first grade lifting device which drives the secondary grade small vehicle to make a vertical lifting movement as a whole, that is, the first grade vertical lifting movement, thereby realizing the conversion between higher travel height and lower operational height.
Description
Affiliated technical field
The utility model relates to a kind of walking dolly of differing heights operation, especially makes sample devices realize the walking dolly of higher headroom and low operation height.
Background technology
At present, known sampling walking dolly structure is to be formed by connecting by trolley frame, running gear, jacking system and sampling setup, and sampling setup is fixed together with jacking system, realizes vertical operation by jacking system.In some sampling occasions, there is different headrooms in same sample space, allows sampling setup to carry out lift work on low operation height loop cycle ground, rises to higher headroom after entire job finishes.The vertical stroke of sampling setup is divided into idle travel and forced stroke, because the diff-H of higher headroom and low operation height causes stroke long, makes the entire job time longer, even can not satisfy the requirement that links with miscellaneous equipment.
Summary of the invention
In order to overcome existing walking dolly in long deficiency of some sampled field cooperation industry times, the utility model provides a kind of two-stage lifting walking dolly, and this two-stage lifting walking dolly can not only be realized vertical Working motion, and has effectively reduced production time.
The technical scheme that its technical matters that solves the utility model adopts is: at former trolley frame is that peripheral increase by the one cover trolley frame of secondary trolley frame is the one-level trolley frame, the one-level trolley frame is connected with the secondary trolley frame by the one-level jacking system, it is the one-level perpendicular movement that one-level jacking system drive secondary trolley frame integral body is in vertical motion, and realizes the conversion of higher headroom and low operation height; Two grade of ascend and descend device guiding parts are with secondary trolley frame captive joint, and it is the secondary vertical displacement movement that sampling setup is driven along two grade of ascend and descend device guiding parts perpendicular movement by the two grade of ascend and descend device.During operation, one-level jacking system drive secondary trolley frame is reduced to low operation height by higher headroom, and sampling setup is carrying out lift work circularly at low operation height positional cycle, and secondary trolley frame integral body rose to higher headroom after entire job finished.Sampling setup needn't be at every turn from higher headroom lifting like this, thereby has shortened duty cycle, has reached the purpose that reduces production time.
The beneficial effects of the utility model are, can carry out the conversion of higher headroom and low operation height easily when realizing perpendicular movement, and equipment has been accelerated cycle of run at the low continuous lift work of operation height, has reduced production time.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further specified.
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the left view of the utility model embodiment.
1. running gears among the figure, 2. one-level jacking system guiding parts, 3. one-level trolley frame, 4. one-level jacking system, 5. secondary trolley frame 6. two grade of ascend and descend devices, 7. two grade of ascend and descend device guiding parts, 8. sampling setup.
The specific embodiment
In Fig. 1, Fig. 2, running gear (1) is fixed on the middle part of one-level trolley frame (3), one-level jacking system (4) is fixed on the top of one-level trolley frame (3), one-level jacking system guiding parts (2) is fixed on the inwall of one-level trolley frame (3), secondary trolley frame (5) is suspended in the one-level trolley frame (3) by one-level jacking system (4), drives along one-level jacking system guiding parts (2) by one-level jacking system (4) and realizes secondary trolley frame (5) vertical displacement movement.Two grade of ascend and descend device guiding parts (7) are captiveed joint with secondary trolley frame (5), and sampling setup (8) drives along two grade of ascend and descend device guiding parts (7) by two grade of ascend and descend device (6) and realizes vertical displacement movement.
Claims (3)
1. walking dolly, the secondary trolley frame is set in the one-level trolley frame, the secondary trolley frame can lifting in the one-level trolley frame, it is characterized in that: the secondary trolley frame can vertically rise to and form higher headroom in the one-level trolley frame, also can vertically stretch out the one-level trolley frame and reduce to low operation height.
2. walking dolly according to claim 1 is characterized in that: the secondary trolley frame is connected with the one-level trolley frame by the one-level jacking system.
