Accompanying drawing explanation

Fig. 1 is the schematic diagram according to the expansion gear for splitting stone equipment of the present utility model.

Detailed description of the invention

Fig. 1 schematically shows according to the expansion gear 5 for splitting stone equipment of the present utility model.As shown in the figure, split stone equipment and comprise hydraulic power source 1, hydraulic tube 2 and expansion gear 5, hydraulic tube 2 is connected between hydraulic power source 1 and expansion gear 5.When carrying out splitting lapicide and doing, first hole on building stones (not shown), then expansion gear 5 is arranged in the hole of having bored.The size and shape in hole is arranged to similar to expansion gear 5 and just can the wall of extruded hole after expansion gear 5 expands a little.Certainly, use multiple expansion gear 5 carry out splitting lapicide do time, the multiple hole equal with an expansion gear 5 quantity and expansion gear 5 is correspondingly set in each hole of should drilling on building stones.Hydraulic power source 1 is for providing fluid under pressure for expansion gear 5; And preferably, hydraulic power source 1 is hydraulic hand-pump or electric hydraulic pump, and hydraulic tube 2 is high-pressure oil pipes.As shown in Figure 1, expansion gear 5 is cut open along its axis, more clearly to show its internal construction.The expansion tube 53 that expansion gear 5 comprises the first expansion housing 51, second expansion housing 55 and is made up of cloth, described cloth is preferably non-woven fabrics.Splitting under the good state of stone device assembles, the first expansion housing 51 and the second expansion housing 55 opposite each other and form cavity between which, expansion tube 53 is arranged in the cavity and near the first expansion housing 51 and the second expansion housing 55.In a preferred embodiment, the first expansion housing 51 and the second expansion housing 55 are semicircular, and described cavity can be any suitable shape such as circle, ellipse, rhombus.Specifically, the outlet of hydraulic power source 1 is connected with the joint 4 of expansion tube 53 by hydraulic tube 2.When hydraulic power source 1 starts, the fluid under pressure in hydraulic power source 1 is transported to expansion tube 53 through hydraulic tube 2 and joint 4, thus expansion tube 53 is expanded and extrudes the first expansion housing 51 and the second expansion housing 55.To expand and in the process of extrusion expansion housing 51,55, expansion tube 53 is subject to frictional force and the extruding force of expansion housing at expansion tube 53, therefore can very quick-wearing.The expansion tube anti-wear performance made with cloth is fabulous, and application life of expansion tube 53 that therefore cloth is made is extended greatly.The anti-wear performance of non-woven fabrics is stronger than common cloth, and therefore the life-span of non-woven fabrics expansion tube is longer than the life-span of common cloth expansion tube.First and second expansion housings 51,55 extrude building stones owing to being squeezed.According in expansion gear 5 of the present utility model, when pressure hydraulic power source 1 being arranged to the fluid under pressure provided enough large (hydraulic tube 2 can bear this pressure) is to make expansion tube 53 expand and to extrude first and second expansion housing 51,55, enough large to the extruding force of building stones, thus this extruding force makes building stones ftracture.It should be pointed out that all parts in Fig. 1 is not draw in proportion, in order to details can be shown better, the illustrated dimensions of expansion gear 5 is expanded.Therefore, the illustrated dimensions in accompanying drawing between all parts is not intended to imply the relative size of parts or limit.

In a preferred embodiment, the inner surface of expansion tube 53 is through plastics processing.Due to the plasticizing of inner surface, the liquid in expansion tube 53 can not leak out this element.In a preferred embodiment, expansion tube 53 is also provided with enhancement layer (not shown) on its outer surface, and this enhancement layer is bonded to polyester fiber on this external surface or carbon fiber.In addition, preferably, expansion tube 53 also comprises wearing layer (not shown), and described wearing layer is bonded in the polytetrafluoroethylene (PTFE) on described enhancement layer external surface.As its name suggests, enhancement layer can increase the intensity (particularly, strengthening the withstand voltage properties of expansion tube) of expansion tube 53, and wearing layer can increase the anti-wear performance of expansion tube 53 thus reduce the wearing and tearing of expansion tube 53 within unit service time further.In a preferred embodiment, split stone equipment and also comprise energy distributor 3 for regulating flow from the fluid of hydraulic power source 1 or pressure, described energy distributor 3 is connected between hydraulic power source 1 and expansion gear 5 by hydraulic tube 2.Alternatively, energy distributor 3 can be one for the hydraulic control valve of the flow or pressure that regulate fluid or also can be the flow divider being divided into multiply for the fluid in self-hydraulic in future source 1.It is pointed out that a plurality of fluids that flow divider separates correspondingly is fed to the equal multiple expansion gears of quantity 5 (particularly, being fed to multiple expansion tubes 53 that quantity is equal).In this specific embodiment, with multiple expansion gear 5, one block of building stones is ftractureed, this makes it possible to make building stones stressed evenly and better to the control effects of building stones cracking, therefore often use multiple expansion gear to ftracture to one block of building stones in the art.

So far, shown by reference to the accompanying drawings preferred embodiment describes the technical solution of the utility model, but those skilled in the art are it is easily understood that protection domain of the present utility model is obviously not limited to these detailed description of the invention.Under the prerequisite not departing from principle of the present utility model, those skilled in the art can make equivalent change or replacement to correlation technique feature, and these changes or the technical scheme after replacing it all will fall within protection domain of the present utility model.
