Detailed description of the invention
Fig. 1 is according to the schematic diagram splitting stone equipment of the present utility model.As shown in Figure 1, this splits stone equipment and comprises hydraulic power source 1, hydraulic tube 2 and expansion gear 5, and hydraulic tube 2 is connected between hydraulic power source 1 and expansion gear 5.It should be noted that, in order to clearly illustrate the expansion gear be arranged in building stones to be cracked, being broken away along its pre-manufactured hole for building stones shown in Fig. 1, do not draw the hatching line of building stones for the ease of indicating Reference numeral, but expansion gear 5 correspondingly not cut along this hatching line open.As shown in Figure 1, when carrying out splitting lapicide and doing, first prefabricated multiple hole 6 on building stones, the quantity in hole 6 is equal with the quantity of expansion gear 5, correspondingly arranges an expansion gear 5 in each hole.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.Although the stone equipment that splits shown in Fig. 1 has 4 expansion gears 5, should be understood that, the expansion gear that the utility model also can arrange other quantity except 4 carries out splitting lapicide's work.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.Hydraulic power source shown in Fig. 1 is hydraulic hand-pump and comprises manual lever 11, pressure sensor 12, pumps hydraulic fluid port 13 and pump body 14.Split stone equipment and also preferably include 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.In the preferred embodiment illustrated in fig. 1, energy distributor 3 comprises distributor body 31, distributor oil-in 32, distributor first oil-out 33, distributor second oil-out 34, distributor the 3rd oil-out 35 and distributor the 4th oil-out 36.When not arranging energy distributor 3, handle manual lever 11 by the liquid pressing in pump body 14, fluid under pressure enters expansion gear 5 from pumping hydraulic fluid port 13 via hydraulic tube 2.When being provided with energy distributor 3, fluid under pressure enters distributor body 31 from pumping the upstream tube 21 of hydraulic fluid port 13 via hydraulic tube 2 by distributor oil-in 32, and the fluid under pressure obtained from distributor oil-in 32 is assigned to distributor first oil-out 33, distributor second oil-out 34, distributor the 3rd oil-out 35 and distributor the 4th oil-out 36 by distributor body 31.Fluid under pressure enters corresponding expansion gear 5 respectively by these distributor oil-outs via the first arm 22, second arm 23 of hydraulic tube 2, the 3rd arm 24 and the 4th arm 25.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 size of parts and relative size or limit.
Fig. 2 is the cross-sectional view of the expansion gear for splitting stone equipment of the prior art.This expansion gear is substantially in cylindric.Expansion gear is depicted as and is arranged in the pre-manufactured hole 6 of building stones to be cracked in fig. 2, and expansion gear is cut open more clearly to show its internal construction by along its circular cross section.Expansion gear comprises the first expansion housing 51', the second expansion housing 55' and expansion tube 53'.Splitting under the good state of stone device assembles, the first expansion housing 51' and the second expansion housing 55' is opposite each other and form cavity between which, and expansion tube 53' is arranged in the cavity and near the first expansion housing 51' and the second expansion housing 55'.Can see, although expansion tube 53' and the first expansion housing 51' and the second expansion housing 55' near, still have space between them.When hydraulic power source 1 starts, the fluid under pressure in hydraulic power source 1 is transported to expansion tube 53', thus expansion tube 53' is expanded and extrudes the first expansion housing 51', the second expansion housing 55'.Along with the expansion of expansion tube 53', expansion tube 53' extrudes first and second expansion housing 51', 55' and expansion tube 53' becomes oval from circle, thus the area that expansion tube 53' extrudes building stones becomes large.As shown in Figure 2, expansion tube 53' is applied to the power of first and second expansion housing 51', 55' along the transmission of arrow F indicated direction.Obviously, expansion tube 53' too disperses via the direction of the extruding force that the first and second expansion housing 51' and 55' transmit, and does not focus on the direction of building stones cracking, is unfavorable for the cracking of building stones.Further, expansion tube 53' outwards expands along the 360 ° of circumferencial directions of self, expansion tube 53' circumferentially not with expansion housing near part can not provide extruding force for expansion housing.This makes the efficiency of whole hydraulic system very low, serious waste energy.
Fig. 3 is the cross-sectional view according to the expansion gear for splitting stone equipment of the present utility model.This expansion gear 5 is also substantially in cylindric.Expansion gear 5 is depicted as and is arranged in the pre-manufactured hole 6 of building stones to be cracked, and Fig. 3 also show the expectation divisural line 100 at the expectation cracking place at building stones.Expansion gear 5 is cut open more clearly to show its internal construction along its circular cross section, expansion gear 5 comprises the first expansion housing 51, second expansion housing 55 and expansion tube 53.The connection of hydraulic tube 2 and expansion gear 5 realizes particular by being connected with the expansion tube 53 of expansion gear 5 by hydraulic tube 2.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.When fluid under pressure is transported to expansion tube 53, expansion tube 53 expands and extrudes the first expansion housing 51 and therefore the second expansion housing 55, first and second expansion housing 51,55 extrudes building stones and building stones are ftractureed.Preferably, the external surface of the first expansion housing 51 and the second expansion housing 55 is all semicircle, first expansion housing 51 comprises and comprises two inner surface-three inner surfaces 551 for the formation of cavity and the 4th inner surface 552 for the formation of two inner surface-the first inner surfaces 511 of cavity and the second inner surface 512, second expansion housing 55.Preferably, as shown in cross-sectional view-Fig. 3 of expansion gear, the cross section of the cavity surrounded by the first inner surface 511, second inner surface 512, the 3rd inner surface 551 and the 4th inner surface 552 is in assembled state rhombus, and namely 4 edge lengths of the quadrangle of the cross section of cavity are equal.The position of expansion gear 5 in pre-manufactured hole 6 is arranged to, and makes the lozenge shape cross-section of described cavity diagonal (diagonal separated with the second expansion housing 55 by the first expansion housing 51-namely in the cross section of expansion gear 5 by diagonal that inner surface 511 is connected with the intersection point of 552 with intersection point and the inner surface 512 of 551) and estimates that the straight line at divisural line 100 place overlaps.
In this specific embodiment, when fluid under pressure enters expansion tube 53, expansion tube 53 expands, thus extrude the first expansion housing 51 along arrow F1 and F2 direction respectively at two some places that expansion tube 53 contacts with the first inner surface 511, second inner surface 512 respectively, and extrude the second expansion housing 55 along arrow F3 and F4 direction respectively at two some places that expansion tube 53 contacts with the 3rd inner surface 551, the 4th inner surface 552 respectively.Along with the expansion of expansion tube 53 and appearance and size become large, expansion tube 53 and the first inner surface 511, second inner surface 512, the 3rd inner surface 551 4 of contacting with the 4th inner surface 552 extrude and a little become 4 little crush-zones and expansion tube 53 is out of shape.But the contact area of these 4 crush-zones is all little, and therefore extruding force dispersion is not obvious, we still can think that expansion tube 53 extrudes two expansion housings at 4 extruding contact point places.Expansion tube 53 along arrow F1 direction for the first expansion housing 51 provides the first extruding force F1, along arrow F2 direction for the first expansion housing 51 provides the second extruding force F2.First extruding force F1 and the second extruding force F2 forms the first extruding F12 with joint efforts along the direction of arrow F12.Expansion tube 53 along arrow F3 direction for the first expansion housing 55 provides the 3rd extruding force F3, and along arrow F4 direction for the first expansion housing 51 provides the 4th extruding force F4.3rd extruding force F3 and the 4th extruding force F4 forms the first extruding F34 with joint efforts along the direction of arrow F34.The cross section of the cavity encompassed due to the first expansion housing 51 and the second expansion housing 55 is rhombus, and rhombus character to be diagonal mutually vertical and divide equally and every bar diagonal divides one group of diagonal angle equally, so the equal and opposite in direction of F1 and F2, direction are symmetrical relative to F12, and the equal and opposite in direction of F3 and F4, direction are symmetrical relative to F34, thus known first extruding make a concerted effort F12 and second extrude make a concerted effort F34 equal and opposite in direction direction contrary, the first extruding force F12 and the second extruding force F34 all with perpendicular to expectation divisural line 100 direction be applied to building stones.That is, except making a concerted effort F12 and extruding force F3 and extruding force F4 is merged into extruding and makes a concerted effort except F34 extruding force F1 and extruding force F2 being merged into extruding, the extruding force provided by expansion tube 53 is not almost lost, most of expansion force of expansion tube 53 is all directed to the direction of building stones cracking by the diamond structure of described cavity, compared with the expansion gear of prior art, which greatly improves energy utilization efficiency.When angle between the angle shape of lozenge shape cross-section is arranged between F1 and F2 and F3 and F4 is all smaller, the energy utilization efficiency of expansion gear 5 is higher.Preferably, the angle between the first inner surface 511 and the second inner surface 512 and the angle between the 3rd inner surface 551 and the 4th inner surface 552 are in the scope of 30 degree to 150 degree.More preferably, the angle between the first inner surface 511 and the second inner surface 512 and the angle between the 3rd inner surface 551 and the 4th inner surface 552 are all 75 degree.
Fig. 4 is the cross-sectional view of the expansion gear for splitting stone equipment as shown in Figure 3, is provided with two Expandable strip in described expansion gear.As shown in Figure 4, expansion gear 5 can also be arranged to comprise the first Expandable strip 52 and the second Expandable strip 54.First and second Expandable strip 52,54 are separately positioned on expansion tube 53 and between the first expansion housing 51 and the second expansion housing 55, near two positions that both preferably respectively in opposite disposed cavity between the first expansion housing 51 and the second expansion housing 55 contact with each other (top in Fig. 4 and bottom).Alternatively, the Expandable strip of other quantity except 2 Expandable strip also can be set according to expansion gear 5 of the present utility model, such as, include but not limited to 1,3,4,5 and 6.As shown in Figure 4, the inner surface that the first expansion housing 51 and the second expansion housing 55 form cavity completely and expansion tube 53 near but and still have some spaces between expansion tube 53, Expandable strip is just arranged in described space.Described space is preferably close to described contact position.When fluid under pressure is transported to expansion tube 53, expansion tube 53 is expanding and is also expanding while extruding the first expansion housing 51 and the second expansion housing 55 and extrude the first and second Expandable strip 52,54.Now, owing to being subject to the extruding of expansion tube 53, first expansion housing 51 and the second expansion housing 55 towards deviate from expansion tube 53 and the direction that building stones are ftractureed (namely, as two arrow F12 and F34 indicated direction in Fig. 4) mobile, make both extruding building stones and both contact site no longer contacts with each other but slowly separates each other, and the first Expandable strip 52 and the second Expandable strip 54 are also respectively towards deviating from the direction of expansion tube 53 (namely, with the direction that the F12 of arrow shown in Fig. 4 is vertical with F34 indicated direction) mobile, two Expandable strip are inserted between the first expansion housing 51 with the second expansion housing 55 at two contact positions respectively two expansion housings are separated, and therefore help extruding and promote two expansion housings, thus help two expansion housing extruding building stones further.The component of the extruding force provided is helped to be applied on building stones along the direction being parallel to arrow F12 and F34 as shown in Figure 4 middle finger by two Expandable strip 52 and 54.Preferably, the first expansion housing 51 and the second expansion housing 55 are arranged to equal and opposite in direction and opposite disposed relative to expansion tube 53, and the first Expandable strip 52 is arranged to equal and opposite in direction with the second Expandable strip 54 and opposed relative to expansion tube 53.The power that this set makes expansion tube 53 be applied to building stones to be cracked by the first and second expansion housing 51,55 and first and second Expandable strip 52,54 is larger and be uniformly distributed.In addition, expansion housing and Expandable strip opposite disposed relative to expansion tube 53 also make expansion tube 53 be subject to the reaction force of expansion housing and Expandable strip size and Orientation evenly, thus the breakage of expansion tube 53 can be slowed down.In a preferred embodiment, the cross section of the first and second Expandable strip 52,54 is trapezoidal or triangle, and the sharp-pointed position (trapezoidal upper base or a leg-of-mutton angle) of the first and second Expandable strip 52,54 is arranged towards the direction vertical with F34 indicated direction with arrow F12 as shown in Figure 4 respectively.Described sharp-pointed position is against the inner surface of the first expansion housing 51 and the second expansion housing 55, and the generous position (trapezoidal bottom or the leg-of-mutton end) of the first and second Expandable strip 52,54 is against the external surface of described expansion tube 53.So, first and second Expandable strip 52, the first and second expansion housings 51 can be inserted along the direction of divisural line 100 more easily respectively in the sharp-pointed position of 54, between two contact positions of 55, and along with two Expandable strip continue move ahead, two generous positions that are trapezoidal or triangle Expandable strip are also inserted between the contact position of two expansion housings, make due to the first and second Expandable strip 52, 54 pairs of the first and second expansion housings 51, 55 oppress and make both trend respectively towards the direction movement being roughly parallel to arrow F12 and F34 rear stronger, cause the first and second Expandable strip 52, 54 pairs of the first and second expansion housings 51, the squeezing action of 55 is stronger.Therefore, first and second Expandable strip 52,54 are larger along being roughly parallel to the extruding force that arrow F12 and F34 indicated direction be delivered on building stones by the first and second expansion housings 51,55, and this extruding force is considerably beyond the extruding force be subject to by building stones when not arranging Expandable strip as a rule.Preferably, generous position that is trapezoidal or triangle Expandable strip is arcs of recesses, operationally to adapt to the external surface shape of expansion tube 53.So, extruding force being more evenly distributed at generous position that expansion tube 53 provides for Expandable strip 52,54, also therefore improve the power being provided to the first and second expansion housings 51,55 by Expandable strip 52,54, expansion tube 53 is subject to reaction force that is trapezoidal or the generous position of triangle Expandable strip and is also more evenly distributed in addition, avoids the damage that expansion tube 53 causes due to discontinuity.In sum, two Expandable strip 52 and 54 are fairly obvious to the help of broken building stones.Although opposite disposed 2 Expandable strip 52 and 54 have many more outstanding advantages, but by description above it is easily understood that, the Expandable strip of other quantity except 2 Expandable strip is set according to expansion gear 5 of the present utility model, such as, when including but not limited to 1,3,4,5 and 6, can realize equally helping extruding building stones and the object that building stones are ftractureed by Expandable strip.It should be understood that equally, when arranging the Expandable strip of other quantity except 2 Expandable strip according to expansion gear 5 of the present utility model, the cross section of Expandable strip also can be arranged to trapezoidal or triangle and improve and help by Expandable strip the extruding force that is provided on building stones.
