Abstract
The utility model relates to a novel suspension pillar, which mainly consists of a cylinder body, a cylinder column, a base, a cylinder column sleeve, a circular handle, a sealing cover, a top cover, a recovery spring and a liquid injection valve body. The design structure of the utility model is that the upper part of the cylinder body is provided with a cylinder sleeve; the internal wall of the cylinder sleeve is provided with a step through hole; the upper step hole wall and the lower step hole wall are provided with a plurality of circular channels where sealing rings are arranged; the cylinder body and the cylinder column are connected with each other; furthermore, the external wall of the cylinder column sleeve is welded by the circular handle; the middle part of the cylinder column is provided with a radial through hole, through which the liquid passes in and out; the radial through hole is communicated with the radial through hole where the liquid passes and which is welded on the liquid injection valve body of the external wall. The novel suspension pillar has the beneficial effect that the height of the liquid injection position is reduced, the usage operation is convenient and the problem of potential safety hazard which exists at the original suspension pillar liquid injection position is solved.
Description
Technical field
The utility model relates to a kind of novel suspension pillar, especially establishes the supporting that is used for mine down-hole mining work plane, also is applicable to the occasion that other needs supporting.
Background technology
A kind of suspension pillar that is usually used in mine down-hole mining work plane is at present seen Fig. 1, it be with the fluid injection Position Design on the handgrip body, there are the following problems in actual use for this suspension pillar: 1, pillar fluid injection position height, 2, prop drawing speed is slower, 3, use operation inconvenience.
Summary of the invention
In view of the deficiency of technology, the purpose of this utility model is that former suspension pillar is improved, liquid injection port on the handgrip body is cancelled, fluid injection valve body of specialized designs wears and is fixed on the pillar oil cylinder, by its fluid injection and drainage, reaching provides a kind of compact conformation reasonable, have the fluid injection position height and reduce, prop drawing speed significantly improves, the novel suspension pillar that supporting intensity significantly improves.
The utility model suspension pillar, it comprises cylinder body, cylinder post, is located at the cylinder column sleeve and the base of cylinder body and cylinder post junction, inner chamber is provided with seal cover in the cylinder column top, outer end, cylinder column top is provided with top cover, a back-moving spring that is connected between centre position, seal cover in cylinder post inner chamber bottom and the base centre position, be located at the fluid injection valve body on the outer wall of cylinder post middle part, the fluid injection valve body is provided with the liquid in-out passage that is communicated with oil cylinder and triple-use valve.
The utility model suspension pillar, the cylinder column sleeve inwall of described cylinder body and cylinder post junction is provided with ladder hole, has a plurality of ring-shaped grooves that sealing ring is set on its going up or down stairway hole wall, and cylinder column sleeve outer wall welds annular handgrip.Cylinder post middle part is provided with the radial direction through hole of turnover liquid, with the liquid in-out channel connection on the fluid injection valve body that is welded on the outer wall.The fluid injection valve body is to have the cavity that cooperates with cylinder body by a side, and opposite side has a metal siamese part of the cavity composition that cooperates with triple-use valve, and the center line of two cavity is vertical mutually, and is provided with the turnover liquid radial direction through hole of intercommunication.
The beneficial effects of the utility model are: 1, fluid injection position height reduces, and uses easy to operately, has solved the problem that there is potential safety hazard in former suspension pillar fluid injection position height.2, re-injection speed significantly increases, and supporting efficient improves, and has solved the slow excessively problem of former suspension pillar prop drawing speed.3, the configuration of cylinder post and cylinder body length is reasonable, and supporting intensity significantly improves, and has solved the problem of former suspension pillar post strength deficiency alive, easy bending deformation.

The specific embodiment
Be described in further detail below in conjunction with accompanying drawing 2, accompanying drawing 3,4 couples of embodiment of the present utility model of accompanying drawing:
The utility model suspension pillar, it mainly is made up of cylinder body 1, cylinder post 2, base 3, cylinder column sleeve 4, annular handgrip 5, seal cover 6, top cover 7, back-moving spring 8 and fluid injection valve body 9.Its project organization is: the bottom at cylinder body 1 and cylinder post 2 is provided with base 3; On the top of cylinder body 1 cylinder column sleeve 4 is set, the inwall 41 of cylinder column sleeve 4 is provided with ladder hole, has a plurality of ring-shaped grooves that sealing ring is set on its upper and lower ladder hole wall, cylinder body 1 is connected the annular handgrip 5 of outer wall 42 welding of cylinder column sleeve 4 with cylinder post 3.Interior top of chamber at cylinder post 2 is provided with seal cover 6, and the top, outer end of cylinder post 2 is provided with top cover 7; In the inner chamber of cylinder post 2, be connected a back-moving spring 8 between the centre position of the centre position, bottom of seal cover 6 and base 3.The middle part of cylinder post 2 be provided with the turnover liquid radial direction through hole 21, be welded on outer wall on fluid injection valve body 9 on liquid in-out entire body radial direction through hole 93 be communicated with; Fluid injection valve body 9 is to have the cavity 91 that cooperates with cylinder body 1 by a side, and opposite side has a metal siamese part of cavity 92 compositions that cooperate with triple-use valve, and the center line of two cavity 91,92 is vertical mutually, and is provided with the turnover liquid radial direction through hole 93 of intercommunication.
Its operating principle: triple-use valve is connected fluid injection valve body 9, open triple-use valve fluid injection in cylinder body 1, liquid enters the annular housing of cylinder body 1 and 2 formation of cylinder post by the through hole on the fluid injection valve body 9 93, and enter cylinder post 2 inner chambers from the radial hole of cylinder post 2 lower ends, inject when reaching certain pressure along with liquid is continuous, cylinder post 2 upwards rises, until the position of withstanding required support.When cancellation is supported, start depressurized system, under back-moving spring 8 effects, the former road of liquid is returned, the every injection of liquid and releasing once, and cylinder post 2 just supports and falls post once, finishes a working cycles.
