Abstract
The utility model relates to the field of lifting jack accessories, in particular to a lifting jack support frame. The utility model aims at providing the lifting jack support frame through which a lifting jack can be used for supporting at a plurality of points. The technical scheme applied is that the lifting jack support frame comprises a load-bearing platform, a base seat and at least three groups of hydraulic pipe fittings. Each group of hydraulic pipe fittings is composed of an outer tube, an inner tube, a piston and a controllable one-way valve. One end of each outer tube is fixedly connected on the lower surface of the load-bearing platform, and one end of each inner tube is fixedly connected on the upper surface of the base seat. Each inner tube stretches into each outer tube, and the outer wall of each inner tube is in sealing fit with the inner wall of each outer tube with liquid. A sealed upper cavity inside each group of hydraulic pipe fittings is formed between each inner tube and each outer tube. Each piston is placed inside each inner tube, and a sealed lower cavity of each group of hydraulic pipe fitting is formed between each inner tube and each piston, wherein space between each inner tube and each piston is sealed with the liquid. Each upper cavity is communicated with each lower cavity through one controllable one-way valve, flowing direction of each controllable one-way valve is from each lower cavity to each upper cavity, and bottom end face of each piston is communicated with atmosphere. The lifting jack support frame can be widely used in mating strut members which are used when the lifting jack supports the plurality of points or supporting journey of the lifting jack is long.
Description
Technical field
The utility model relates to jack auxiliary field, especially a kind of jack supporting frame.
Background technique
When the situations such as a lot of occasions, particularly prominent chance automobile flat tire of daily life, need to finish support with jack, so that maintenance at present.But also few with the matching used auxiliary member of jack on the market, and under many circumstances, need to finish with an only jack support of multiple spot, produced thus a lot of inconveniences.And when using jack, because the object contact face that supports with needs is less, have the problem of stability of strutting system, thus even can bring potential safety hazard.
The model utility content
Technical problem to be solved in the utility model provides a kind of and jack and supports the use, and guarantees the jack supporting frame that jack can multiple spot uses.
The technological scheme that its technical problem that solves the utility model adopts is: the jack supporting frame, comprise bearing table, base, at least three group hydraulic tube pieces, hydraulic tube piece is by outer tube, inner tube, piston and controllable check valve consist of, one end of outer tube is fixedly connected on the lower surface of bearing table, one end of inner tube is fixedly connected on the upper surface of base, inner tube stretch in the outer tube and the inwall of the outer wall of inner tube and outer tube between liquid sealing cooperate, form the airtight epicoele in the hydraulic tube piece between inner tube and the outer tube, piston is arranged in the inner tube and the airtight cavity of resorption in the liquid sealing formation hydraulic tube piece between inner tube and the piston, communicate by controllable check valve between epicoele and the cavity of resorption, the direction that flows to of controllable check valve is that cavity of resorption flows to epicoele, and the piston bottom end face communicates with atmosphere.
Concrete, being provided with cavity, inner orifice and gross blow hole in the base, cavity communicates by inner orifice with the piston bottom end face, and cavity communicates by gross blow hole with atmosphere.
Further be: the middle part of bearing table lower surface is provided with a thickening boss.
The beneficial effects of the utility model are: consist of into hydraulic tube piece by inner tube, outer tube, piston and one-way valve sealing.When supporting frame was propped up, hydraulic oil flow in the epicoele through controllable check valve from cavity of resorption.After removing jack, owing to the inhibition of controllable check valve to hydraulic oil, hydraulic oil continues to be enclosed in the epicoele, has guaranteed that carrier still can independently continue supporting object weight, thereby jack can have been removed, but reached the purpose that the jack multiple spot uses.Supporting plane has also strengthened the stability that supports.When finishing to support, only need to regulate controllable check valve, hydraulic oil can reverse flowing in the original oil storing tube.Can be widely used in jack multi-point support or jack and support the supporting supporting element of stroke when longer.

Fig. 2 is base schematic diagram of the present utility model.
Fig. 3 is hydraulic tube principle schematic of the present utility model.
Fig. 4 is assembling schematic diagram of the present utility model.
Be labeled as among the figure: bearing table 1, outer tube 2, thickening boss 3, base 4, gross blow hole 5, cavity 6, inner tube 7, controllable check valve 8, cavity bore 9, piston 10, hydraulic tube piece 11, epicoele 12, cavity of resorption 13.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
The jack supporting frame comprises bearing table 1, base 4, at least three group hydraulic tube pieces 11, and hydraulic tube piece 11 is made of outer tube 2, inner tube 7, piston 10 and controllable check valve 8.Hydraulic tube piece 11 is main members of jack supporting frame, one end of outer tube 2 is fixedly connected on the lower surface of bearing table 1, one end of inner tube 7 is fixedly connected on the upper surface of base 4, inner tube 7 stretch in the outer tube 2 and the inwall of the outer wall of inner tube 7 and outer tube 2 between liquid sealing cooperate, form the airtight epicoele 12 in the hydraulic tube piece 11 between inner tube 7 and the outer tube 2, piston 10 is arranged in the inner tube 7 and the airtight cavity of resorption 13 in the liquid sealing formation hydraulic tube piece 11 between inner tube 7 and the piston 10, communicate by controllable check valve 8 between epicoele 12 and the cavity of resorption 13, the direction that flows to of controllable check valve 8 is that cavity of resorption 13 flows to epicoele 12, and piston 10 bottom ends communicate with atmosphere.When the jack supporting frame was propped up, epicoele 12 interior meetings produced vacuum.Because it is that cavity of resorption 13 flows to epicoele 12 that controllable check valve 8 flows to direction, under the active force of external atmosphere pushing piston, the hydraulic oil of inner chamber 13 flows into epicoele 12 by controllable check valve 8, and is closed in epicoele 12.After taking jack away, the hydraulic oil that is closed in epicoele 12 has supported weight, has guaranteed that the jack supporting frame can the independent support weight, can be widely used in jack multi-point support or jack and support the supporting supporting element of stroke when longer.
In order to prevent that the jack supporting frame is after long-term the use, the passage that piston 10 bottom ends are connected with atmosphere is not blocked, can select further scheme: base 4 interior cavity 6, inner orifice 9 and the gross blow holes 5 of arranging, cavity 6 communicates by inner orifice 9 with piston 10 bottom ends, and cavity 6 communicates by gross blow hole 7 with atmosphere.Owing to there being the buffer function of 6 pairs of dust of cavity, the situation that inner orifice 9 can not occur stopping up, barometric pressure is come in and gone out smoothly when having guaranteed that piston 10 moves up and down, and has ensured that supporting frame effectively works.
In order to increase bearing table rigidity, increase the service life, be provided with a thickening boss 3 at the middle part of bearing table 1 lower surface.
