Abstract
The utility model relates to a hydraulic cushion lifting mechanism for a narrow space, and belongs to the technical field of hydraulic place-taking machines. The hydraulic cushion lifting mechanism for the narrow space is simple in structure and safe in use. According to the technical scheme, the hydraulic cushion lifting mechanism for the narrow space comprises a base, a lifting supporting frame and a hydraulic cushion, wherein the lifting supporting frame is arranged above the base, the hydraulic cushion is arranged between the base and the lifting supporting frame, a liquid inlet is formed in the hydraulic cushion, liquid is fed into or discharged out through the liquid inlet to enable the hydraulic cushion to expand or shrink, and the hydraulic cushion enables the lifting supporting frame to ascend or descend through expansion or shrink of the hydraulic cushion. According to the hydraulic cushion lifting mechanism for the narrow space, the ascent stroke of the lifting supporting frame can be limited through the hydraulic cushion lifting mechanism, the phenomenon that accidents are caused due to the fact that the ascent position is excessively high is prevented, and the hydraulic cushion lifting mechanism for the narrow space is safe in use, simple in structure and especially applicable to the narrow space.
Description
Technical field
A kind of elevating mechanism of the hydraulic die cushion for small space of the utility model, belong to hydraulic pressure machine technology in place field.
Background technology
Machine in place realizes that for the installation in position for underground hydraulic support frame institutional problem proposes fully, installation in position is in backward handwork state always for a long time, work powerful, inefficiency, potential safety hazard are many, change this state-noise very high, each ones at different levels are also all at active development, but still do not have so far a machinery that can be competent to occur, elevating mechanism on existing machine in place is because structure is larger, put to good use not open at narrow space, therefore study a kind of elevating mechanism for small space extremely urgent.
The utility model content
The utility model has overcome the deficiency that prior art exists, and a kind of simple in structure, the hydraulic die cushion for small space elevating mechanism of using safety is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of elevating mechanism of the hydraulic die cushion 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 lifting support frame, be provided with inlet on described hydraulic die cushion, to described inlet topping up or tapping, can make hydraulic die cushion expand or dwindle, described hydraulic die cushion rises lifting support frame or fall by expanding or dwindling.
Be provided with postive stop baffle on described base, 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 described groove.
Described lifting support frame is annular, the setting that adapts of lifting support frame and described hydraulic die cushion.
Be provided with hook on described lifting support frame, 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 utility model compared with prior art has is: the utility model is provided with annular hydraulic die cushion between base and lifting support frame, be provided with inlet on hydraulic die cushion, by inlet to being filled with high pressure liquid in hydraulic die cushion, can make hydraulic die cushion expand, lifting support frame holds up, the weight be placed on lifting support frame is also held up thereupon, the postive stop baffle arranged on base and the hook on 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 utility model is used safety, simple in structure, be specially adapted to small space.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view along A in Fig. 1-A line.
In 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, a kind of elevating mechanism of the hydraulic die cushion for small space of the utility model, 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 lifting support frame 2, be provided with inlet on described hydraulic die cushion 3, to described inlet topping up or tapping, can make hydraulic die cushion 3 expand or dwindle, described hydraulic die cushion 3 rises lifting support frame 2 or fall by expanding or dwindling.
Be provided with postive stop baffle 4 on described base 1, 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 described groove.
Described lifting support frame 2 is annular, the setting that adapts of lifting support frame 2 and described hydraulic die cushion 3.
Be provided with hook 5 on described lifting support frame 2, settings that adapt of described hook 5 and postive stop baffle 4, 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 utility model: when the inlet feed liquor, make the full expansion of annular hydraulic die cushion 3, hold up lifting support frame 2, higher than base 1, and then the picking-up weight, due to the slew gear base in machine in place and the same height of base of the present invention 1, slew gear now can turn round, in addition, link up with 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 larger 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.
The above is explained in detail embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-described embodiment, in the ken possessed those of ordinary skills, can also under the prerequisite that does not break away from the utility model aim, make various variations.
