Abstract
The invention discloses a hydraulic cushion lifting mechanism used in narrow and small space, belongs to the technical field of hydraulic machines for in-place mounting, and aims to technically provide the hydraulic cushion lifting mechanism which is simple in structure, safe to use and can be used in the narrow and small space. The technical scheme includes that the hydraulic cushion lifting mechanism comprises a base, a lifting support frame and a hydraulic cushion, the lifting support frame is arranged above the base, the hydraulic cushion is arranged between the base and the lifting support frame, a liquid inlet is arranged on the hydraulic cushion, liquid in the liquid inlet is filled or discharged to expand or shrink the hydraulic cushion, and the lifting support frame is lifted up or dropped down through expanding or shrinking of the hydraulic cushion. Ascending stroke of the lifting support frame can be controlled, so that accidents due to overhigh ascending positions are avoided; the hydraulic cushion lifting mechanism is safe to use, simple in structure and particularly suitable for the narrow and small space.
Description
Technical field
The present invention is used for the hydraulic die cushion elevating mechanism of small space, belongs to hydraulic pressure machine technology in place field.
Background technology
Machine in place is in order to realize that at the installation in position of underground hydraulic support frame institutional problem proposes fully, installation in position is in backward handwork state always for a long time, it is powerful to work, inefficiency, potential safety hazard are many, it is very high to change this state-noise, each one at different levels are also all at active development, but still there is not a machinery that can be competent to occur so far, elevating mechanism on the existing machine in place is because structure is bigger, put to good use not open at narrow space, it is extremely urgent therefore to study a kind of elevating mechanism for small space.
Summary of the invention
The present invention has overcome the deficiency that prior art exists, and a kind of simple in structure, hydraulic die cushion elevating mechanism that is used for small space of using safety is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the hydraulic die cushion elevating mechanism that is used for small space, comprise base, lifting support frame and hydraulic die cushion, the top of base is provided with lifting support frame, hydraulic die cushion is arranged between base and the lifting support frame, described hydraulic die cushion is provided with inlet, hydraulic die cushion is expanded or dwindles described inlet topping up or tapping, and described hydraulic die cushion rises lifting support frame or fall by expanding or dwindling.
Described base is provided with postive stop baffle, and described postive stop baffle can limit the upward stroke of lifting support frame.
Described hydraulic die cushion is annular, and the bottom correspondence of the top of described base and lifting support frame is provided with groove, and described hydraulic die cushion is arranged in the described groove.
Described lifting support frame is annular, the setting that adapts of lifting support frame and described hydraulic die cushion.
Described lifting support frame is provided with hook, the setting that adapts of described hook and postive stop baffle, the cooperatively interact upward stroke of restriction lifting support frame of described hook and postive stop baffle.
The beneficial effect that the present invention compared with prior art has is: the present invention is provided with the hydraulic die cushion of annular between base and lifting support frame, hydraulic die cushion is provided with inlet, by inlet to charging into high pressure liquid in the hydraulic die cushion, hydraulic die cushion is expanded, lifting support frame holds up, the weight that is placed on the lifting support frame is also held up thereupon, the postive stop baffle that arranges at base and the hook on the lifting support frame cooperatively interact, can the upward stroke of lifting support frame be limited, prevent that lifting position is too high, accidents caused, the present invention uses safety, simple in structure, be specially adapted to small space.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the sectional view along A among Fig. 1-A line.
Among the figure, 1 is that base, 2 is that lifting support frame, 3 is that hydraulic die cushion, 4 is that postive stop baffle, 5 is hook.
The specific embodiment
As shown in Figure 1 and Figure 2, the present invention is used for the hydraulic die cushion elevating mechanism of small space, comprise base 1, lifting support frame 2 and hydraulic die cushion 3, the top of base 1 is provided with lifting support frame 2, hydraulic die cushion 3 is arranged between base 1 and the lifting support frame 2, described hydraulic die cushion 3 is provided with inlet, hydraulic die cushion 3 is expanded or dwindles described inlet topping up or tapping, and described hydraulic die cushion 3 rises lifting support frame 2 or fall by expanding or dwindling.
Described base 1 is provided with postive stop baffle 4, and described postive stop baffle 4 can limit the upward stroke of lifting support frame 2.
Described hydraulic die cushion 3 is annular, and the bottom correspondence of the top of described base 1 and lifting support frame 2 is provided with groove, and described hydraulic die cushion 3 is arranged in the described groove.
Described lifting support frame 2 is annular, the setting that adapts of lifting support frame 2 and described hydraulic die cushion 3.
Described lifting support frame 2 is provided with hook 5, settings that adapt of described hook 5 and postive stop baffle 4, and described hook 5 and postive stop baffle 4 cooperatively interact and limit the upward stroke of lifting support frame 2.
The course of work of the present invention: when the inlet feed liquor, make hydraulic die cushion 3 full expansions of annular, hold up lifting support frame 2, be higher than base 1, and then the picking-up weight, because the slew gear base in the machine in place and base of the present invention 1 are high together, the slew gear of this moment can turn round, in addition, hook 5 and postive stop baffle 4 cooperatively interact and can limit the upward stroke of lifting support frame 2.
The hydraulic die cushion 3 of annular has bigger diameter, and its side grain area * liquid pressure is the load capacity of its picking-up, and the height space that itself occupies is little, therefore, can carry out little spatial altitude heavy duty lifting.
By reference to the accompanying drawings embodiments of the invention have been done detailed description above, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skills possess, can also under the prerequisite that does not break away from aim of the present invention, makes various variations.
