Fig. 2 is according to the schematic diagram splitting stone implement pressure control device of the present utility model.
Detailed description of the invention
Fig. 1 is according to the schematic diagram splitting stone implement of the present utility model.Split stone implement and comprise hydraulic power source 1, hydraulic tube 2, at least one expansion gear 5 and according to pressure control device 10 (this protective device 10 is shown in Figure 2) of the present utility model, hydraulic tube 2 is connected between hydraulic power source 1 and expansion gear 5.When carrying out splitting lapicide and doing, first at least one hole prefabricated on building stones (not shown), is then arranged on expansion gear 5 in the pre-manufactured hole of building stones.The size and shape of pre-manufactured hole is arranged to similar to expansion gear 5 and after expansion gear 5 expands a little, just can be extruded the wall of pre-manufactured hole.Certainly, the pre-manufactured hole on building stones is equal with expansion gear 5 quantity, correspondingly arranges an expansion gear 5 in each hole.Hydraulic power source 1 is for providing fluid under pressure for expansion gear 5; And preferably, hydraulic power source 1 is 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 vertical axis, more clearly to show its internal construction.Expansion gear 5 comprises the first expansion housing 51, second expansion housing 55 and expansion tube 53.Splitting under the state that stone implement 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 outline of the first expansion housing 51 and the second expansion housing 55 is semicircular, and described cavity is circular cavity.Specifically, the connection of hydraulic tube 2 and expansion gear 5 realizes by being connected with expansion tube 53 via hydraulic joint 4 by hydraulic tube 2.When splitting stone implement work, the fluid under pressure in hydraulic power source 1 is transported to expansion tube 53 through hydraulic tube 2 and hydraulic joint 4, thus expansion tube 53 is expanded and extrudes the first expansion housing 51 and the second expansion housing 55.First and second expansion housings 51,55 extrude building stones owing to being squeezed.According in expansion gear 5 of the present utility model, the pressure enough large (hydraulic tube 2 can bear this pressure) of the fluid under pressure that hydraulic power source 1 provides is to make the extruding force of the first and second expansion housings 51,55 pairs of building stones enough large, 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 amplified.Therefore, the illustrated dimensions in accompanying drawing between all parts is not intended to imply the size of parts and relative size or limit.
Fig. 2 is according to the schematic diagram splitting stone implement pressure control device of the present utility model.As shown in Figure 2, pressure control device 10 comprises pressure sensor 101 and overload controller 102, and preferably includes pressure-relief valve 103 and/or stop valve 104.Pressure-relief valve 103 by hydraulic tube 2 or another independently hydraulic tube be connected between expansion gear 5 and hydraulic power source 1 (such as hydraulic pump or fuel tank), and accept the control of overload controller 102.When overload controller 102 shows to occur pressure jump in expansion tube 53 from the signal that pressure sensor 101 receives, overload controller 102 order pressure-relief valve 103 is opened to reduce the pressure of the fluid under pressure flowing to expansion gear 5 (specifically expansion tube 53).Preferably, pressure sensor 101 in a wired fashion or wireless communication mode be connected to overload controller 102.Also illustrate with dashed lines preferred hydraulic power source 1-electric hydraulic pump in Fig. 2, hydraulic power source splits the requisite building block of stone implement to be not comprised in according in pressure control device 10 of the present utility model.When overload controller 102 shows to occur pressure jump in expansion tube 53 from the signal that pressure sensor 101 receives, controller 102 order hydraulic pump 1 shuts down to reduce the pressure of the fluid under pressure flowing to expansion gear 5 (specifically expansion tube 53).In a detailed description of the invention, pressure sensor 101 is arranged on hydraulic tube 2.In one more specifically embodiment, pressure sensor 101 is pressure meter and preferably electro connecting pressure gauge, and this pressure meter is arranged on expansion tube 53 or hydraulic tube 2 place and correspondingly detects pressure change in expansion tube 53 or hydraulic tube 2.In another embodiment, pressure sensor 101 is strain pressure transducers, and is arranged on the surface of hydraulic tube 2 to be learnt the fluid pressure change in hydraulic tube 2 by the STRESS VARIATION measuring this hydraulic tube 2 surface.When carrying out splitting lapicide and doing, along with fluid under pressure enters expansion tube 53 by hydraulic tube 2, fluid under pressure in hydraulic tube 2 and expansion tube 53 increases gradually and pressure increases gradually, both also correspondingly expand thicker gradually, make the surface area of hydraulic tube 2 become large gradually and the power making pressure sensor carrier be subject to two housings also becomes large gradually.In extruding force greatly to the moment making building stones ftracture, the constraint that two expansion housings lose building stones sharply expands outwardly, and the accommodation cavity of expansion tube 53 also sharply expands and becomes large, and the pressure of the fluid under pressure causing it to hold is undergone mutation.The amount entering the fluid under pressure of expansion tube 53 in this moment from hydraulic tube 2 increases severely and considerably beyond the amount of fluid under pressure being now provided to expansion tube 53 by hydraulic power source 1, the amount of the fluid under pressure therefore in hydraulic tube 2 reduces rapidly, and the pressure of the fluid under pressure causing it to hold also is undergone mutation.In building stones cracking moment, the fluid under pressure be contained in expansion tube 53 increases suddenly.Because the building stones cracking fluid under pressure be contained in instantaneously in hydraulic tube 2 reduces suddenly, the pressure in hydraulic tube 2 also can reduce suddenly.The pressure jump in building stones cracking instantaneous expansion pipe 53 or hydraulic tube 2 directly measured by pressure meter, and by this pressure jump signal in a wired fashion or wireless mode be transported to overload controller 102.Overload controller 102 makes at least one in following several responsive measures after receiving pressure jump signal: open pressure-relief valve 103 to discharge the fluid under pressure in expansion tube 53 and/or hydraulic tube 2; Close stop valve 104 to stop carrying fluid under pressure in expansion tube 53 and/or hydraulic tube 2; And make electric hydraulic pump stop carrying fluid under pressure in expansion tube 53 and/or hydraulic tube 2.The fluid under pressure that avoiding problems after building stones cracking in expansion tube continues supercharging, thus achieves the overload protection of expansion tube 53 and extend its application life.In a preferred embodiment, pressure-relief valve 103 of the present utility model by pressurized liquid discharge in fuel tank or hydraulic power source.
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.
