Description
本新型係關於一種連接裝置及應用其之氣動錘結構,尤其指一種利用定位槽提供固定功能的連接裝置及應用其之氣動錘結構。The present invention relates to a connecting device and a pneumatic hammer structure using the same, and particularly to a connecting device that uses a positioning groove to provide a fixed function and a pneumatic hammer structure using the same.
本新型所涉及之技術為鑽孔鑿岩或打樁工程的大型氣動錘結構。相較於一般居家裝潢、機具組裝使用的氣動錘而言,此類大型氣動錘的作用環境主要為地下岩層。The technology involved in the present invention is a large pneumatic hammer structure for drilling rock drilling or piling engineering. Compared with the pneumatic hammers used in general home decoration and machine assembly, the working environment of such large pneumatic hammers is mainly underground rock formations.
大型氣動錘與一般氣動錘的另一差異在於,大型氣動錘不僅需要設置空氣通道以提供氣動衝力,還須設法排出鑽孔時所產生的泥漿、石渣等廢料。先天的結構限制使得大型氣動錘較為脆弱。然因使用特性所致,結構強度卻是大型氣動錘須確保的首要環節。Another difference between large pneumatic hammers and general pneumatic hammers is that large pneumatic hammers not only need to provide air passages to provide pneumatic impulses, but also have to manage to discharge mud, gravel and other waste generated during drilling. Congenital structural constraints make large pneumatic hammers more fragile. However, due to the use characteristics, structural strength is the primary requirement for large pneumatic hammers.
現有的一種大型氣動錘係先以連接裝置組接氣動錘本體,再於氣動錘本體的外圈設置外殼做為保護。由於連接裝置和氣動錘之本體有多種規格,故兩者之間多為螺接固定以方便替換。然而,因為氣動錘本體及外殼的重量極重,上述螺接之固定方式將對連接裝置的螺紋部產生巨大的拉應力。The existing large-scale pneumatic hammer system firstly connects the pneumatic hammer body with a connecting device, and then provides an outer casing for protecting the outer ring of the pneumatic hammer body. Since the connecting device and the body of the pneumatic hammer have various specifications, the two are mostly screwed to facilitate replacement. However, because the weight of the pneumatic hammer body and the outer casing is extremely heavy, the above-mentioned screwing manner will cause a large tensile stress on the threaded portion of the connecting device.
此外,基於鑽孔、打樁的作業環境惡劣且受力不可預測等特性,連接裝置容易在施工過程中意外損壞,導致氣動錘連同外殼在地底與連接裝置脫離,令後續的善後工作十分棘手。In addition, based on the poor working environment and unpredictable force of the drilling and piling, the connecting device is easily damaged accidentally during the construction process, which causes the pneumatic hammer and the outer casing to be separated from the connecting device at the ground, which makes the subsequent after-care work very difficult.
因此,為了克服現有技術的不足之處,本新型提出一種連接裝置及應用其之氣動錘結構,藉由設置定位槽以將連接裝置及氣動錘之本體、外殼穿置固定,防止氣動錘結構因為應力負荷而損壞、脫落。Therefore, in order to overcome the deficiencies of the prior art, the present invention proposes a connecting device and a pneumatic hammer structure using the same, by providing a positioning groove to fix the connecting device and the body and the outer casing of the pneumatic hammer, thereby preventing the pneumatic hammer structure because Damaged and detached due to stress load.
根據本新型之一實施方式,提供一種連接裝置,連接裝置係應用於氣動錘結構,氣動錘結構具有外殼,而外殼又具有貫槽。連接裝置包含至少一個表面,表面上凹設有定位槽,且定位槽容納於外殼內而與貫槽位置相對應,以供連接裝置及外殼被貫穿而相固定。According to an embodiment of the present invention, a connecting device is provided, the connecting device being applied to a pneumatic hammer structure, the pneumatic hammer structure having an outer casing, and the outer casing having a through groove. The connecting device comprises at least one surface, the surface is concavely provided with a positioning groove, and the positioning groove is received in the outer casing corresponding to the position of the groove so that the connecting device and the outer casing are penetrated and fixed.
相較於現有的氣動錘結構,本實施方式額外提供連接裝置及外殼之間的橫向干涉,不僅能夠有效分散連接裝置的負載,亦可確保連接裝置與氣動錘本體、外殼不會因為過載而脫落。Compared with the existing pneumatic hammer structure, the present embodiment additionally provides lateral interference between the connecting device and the outer casing, which can not only effectively distribute the load of the connecting device, but also ensure that the connecting device and the pneumatic hammer body and the outer casing do not fall off due to overload. .
在一實施例中,前述連接裝置可另包含連接部,且前述之表面位於連接部。進一步地,連接部可以為多角柱體。In an embodiment, the connecting device may further comprise a connecting portion, and the aforementioned surface is located at the connecting portion. Further, the connecting portion may be a polygonal cylinder.
前述定位槽可以為凹陷弧面,以方便插銷以任意角度插置固定,並避免插銷發生應力集中問題。The positioning groove may be a concave curved surface to facilitate the insertion and fixation of the pin at an arbitrary angle and to avoid stress concentration of the pin.
在一實施例中,前述貫槽以及表面的數量可以為兩個以上。在此實施例中,兩個貫槽可以位於殼體之相對側,而兩個表面亦位於連接裝置之相對側。亦即,連接裝置可以包含兩個定位槽,並與外殼的兩個貫槽對應貫穿。In an embodiment, the number of the through grooves and the surface may be two or more. In this embodiment, the two through grooves may be located on opposite sides of the housing, and the two surfaces are also located on opposite sides of the connecting device. That is, the connecting device may include two positioning grooves and penetrate through the two through grooves of the outer casing.
在一實施例中,連接裝置可另包含基座,基座容納於外殼內並抵靠外殼之內壁,藉以確保連接裝置和外殼沒有徑向之相對位移。In an embodiment, the attachment means may further comprise a base that is received within the outer casing and abuts against the inner wall of the outer casing to ensure that the attachment means and the outer casing are free of relative radial displacement.
前述之連接裝置可另包含銜接槽,銜接槽凹設於連接裝置之表面且露出外殼,以供銜接外部驅動源(如怪手)。在此實施例中,表面同樣可位於連接部上。The connecting device may further comprise a connecting groove, the engaging groove is recessed on the surface of the connecting device and exposes the outer casing for engaging an external driving source (such as a strange hand). In this embodiment, the surface can likewise be located on the joint.
根據本新型之一實施方式,提供一種氣動錘結構,包含前述任一實施例所述之連接裝置、外殼以及穿置銷。連接裝置與外殼之連接關係如前一本實施方式所述。在本實施方式中,穿置銷係貫穿貫槽及定位槽,以完成連接裝置與外殼之間的限位固定關係。According to an embodiment of the present invention, there is provided a pneumatic hammer structure comprising the connecting device, the outer casing and the wearing pin of any of the preceding embodiments. The connection relationship between the connecting device and the outer casing is as described in the previous embodiment. In the embodiment, the piercing pin is inserted through the through groove and the positioning groove to complete the limit fixing relationship between the connecting device and the outer casing.
在前述貫槽以及表面之數量為兩個的實施例中,氣動錘結構所包含的穿置銷數量為對應的兩個,且各個穿置銷分別貫穿一組貫槽及定位槽。 本實施方式有關於連接裝置之功效已如前述實施方式所載,故此處不再重述。In the embodiment in which the number of the through grooves and the number of the surfaces are two, the number of the piercing pins included in the pneumatic hammer structure is two, and each of the piercing pins respectively penetrates through the set of through grooves and the positioning grooves. The effect of the present embodiment regarding the connection device has been as described in the foregoing embodiments, and therefore will not be repeated here.
為充分瞭解本新型之目的、特徵及功效,茲藉由下述具體之實施例,並配合所附之圖式,對本新型做一詳細說明,說明如後:In order to fully understand the purpose, features and effects of the present invention, the present invention will be described in detail by the following specific embodiments and the accompanying drawings.
請參照圖1A、圖1B以及圖1C,連接裝置200具有至少一個表面201,且表面201凹設有定位槽201A。於圖1A及圖1B中,連接裝置200具有六個表面201,且定位槽201A的數量為兩個,並且凹設在對稱於連接裝置200的其中兩個表面201上。在本實施方式中,連接裝置200具有連接部210,而六個表面201則為連接部210上的不同個面。當然,根據不同設計,連接裝置200也可以包含更多個表面201和定位槽201A。Referring to FIG. 1A, FIG. 1B and FIG. 1C, the connecting device 200 has at least one surface 201, and the surface 201 is recessed with a positioning groove 201A. In FIGS. 1A and 1B, the connecting device 200 has six surfaces 201, and the number of the positioning grooves 201A is two, and is recessed on two of the surfaces 201 of the connecting device 200. In the present embodiment, the connecting device 200 has the connecting portion 210, and the six surfaces 201 are different faces on the connecting portion 210. Of course, depending on the design, the connecting device 200 can also include more surfaces 201 and positioning slots 201A.
再參照圖2、圖3,外殼300具有兩個貫槽310,連接裝置200可局部容納於外殼300內部,而連接部210之部分則由外殼300頂部的連接孔301露出。Referring again to FIGS. 2 and 3, the outer casing 300 has two through grooves 310, and the connecting device 200 can be partially housed inside the outer casing 300, and a portion of the connecting portion 210 is exposed by the connecting hole 301 at the top of the outer casing 300.
在此狀態下,連接裝置200的兩個定位槽201A被隱沒於外殼300內,並且與外殼300的貫槽310位置相對應,可供穿置銷400等外部元件一併貫穿,藉以固定連接裝置200及外殼300。In this state, the two positioning slots 201A of the connecting device 200 are hidden in the outer casing 300, and corresponding to the position of the through slot 310 of the outer casing 300, the external components such as the wearing pin 400 can be penetrated together, thereby fixing the connecting device. 200 and outer casing 300.
須特別說明的是,由於單一組定位槽201A及貫槽310即可對連接裝置200及外殼300發揮穿置拘束效果,故本實施方式並不限定定位槽201A、貫槽310必須為兩組以上。In particular, since the single set of positioning grooves 201A and the through grooves 310 can exert a restraining effect on the connecting device 200 and the outer casing 300, the present embodiment does not limit the positioning groove 201A and the through groove 310 to two or more. .
另外,本實施方式旨在說明連接裝置200與外殼300之固定關係,連接部210僅為方便解說連接裝置200和外殼300的相對位置,故連接部210亦非本實施方式之必要限制。In addition, the present embodiment is intended to explain the fixed relationship between the connection device 200 and the outer casing 300. The connection portion 210 is only necessary to explain the relative positions of the connection device 200 and the outer casing 300. Therefore, the connection portion 210 is not necessarily limited to the embodiment.
在本實施方式中,連接部210為六角柱體,惟此構型並非連接裝置200的必要實施條件。在其他實施例中,連接部210也可以是其他多角柱體。為了方便穿置銷400插入定位槽201A以及貫槽310,定位槽201A可以設計成凹陷弧面,而貫槽310則為圓柱狀的貫孔。In the present embodiment, the connecting portion 210 is a hexagonal cylinder, but this configuration is not a necessary condition for the connection device 200. In other embodiments, the connecting portion 210 can also be other polygonal cylinders. In order to facilitate the insertion of the insertion pin 400 into the positioning groove 201A and the through groove 310, the positioning groove 201A can be designed as a concave curved surface, and the through groove 310 is a cylindrical through hole.
此外,連接裝置200可以包含基座220,基座220可發揮連接裝置200於外殼300內部的徑向拘束效果,以確保連接部210與連接孔301保持同軸狀態,避免因相對位移而發生彎矩。In addition, the connecting device 200 can include a base 220, and the base 220 can exert a radial restraining effect of the connecting device 200 inside the outer casing 300 to ensure that the connecting portion 210 and the connecting hole 301 remain coaxial to avoid bending moment due to relative displacement. .
配合圖4說明,在圖3之狀態下,連接裝置200底端之組接部230係懸空於外殼300內。組接部230的作用在於連接氣動錘的本體600,本體600可由外殼300的底部穿入,且本體600的頂部包含組接端610,組接端610與組接部230可對應螺接。當然,組接端610與組接部230也可以是不同組合方式。4, in the state of FIG. 3, the assembly portion 230 at the bottom end of the connection device 200 is suspended in the outer casing 300. The assembly 230 functions to connect the body 600 of the pneumatic hammer. The body 600 can be inserted through the bottom of the outer casing 300, and the top of the body 600 includes the assembly end 610. The assembly end 610 and the assembly portion 230 can be screwed correspondingly. Of course, the group interface 610 and the assembly portion 230 can also be in different combinations.
上述實施方式與現有大型氣動錘之主要差異在於,氣動錘之外殼300並非先固定於本體600、再連同本體600一起懸吊於連接裝置200的組接部230,而是利用穿置銷400、貫槽310而直接固定於連接裝置200的定位槽201A。The main difference between the above embodiment and the existing large-sized pneumatic hammer is that the outer casing 300 of the pneumatic hammer is not fixed to the body 600 first, and then suspended together with the body 600 to the assembly portion 230 of the connecting device 200, but the wearing pin 400 is used. The groove 310 is directly fixed to the positioning groove 201A of the connecting device 200.
透過上述設置,外殼300施加於連接裝置200的負載可由組接部230轉移至定位槽201A,令外殼300之重量改由連接裝置200所提供之拉力來抗衡,有效地減輕組接部230的應力負荷。Through the above arrangement, the load applied to the connecting device 200 by the outer casing 300 can be transferred from the assembling portion 230 to the positioning groove 201A, so that the weight of the outer casing 300 is countered by the pulling force provided by the connecting device 200, thereby effectively reducing the stress of the connecting portion 230. load.
請配合圖1、圖2參照圖5與圖6,本新型亦可採用氣動錘結構100之整體方式實施。例如,氣動錘結構100可與外部驅動源之驅動桿500連接,而驅動桿500的一側(底部)則具有兩個嵌合槽510,與此相對的,連接裝置200可具有兩個銜接槽201B,同樣可設置於連接部210之表面201。銜接槽201B與定位槽201A在連接部210之方位可以相同或是不同。驅動桿500之嵌合槽510及連接裝置200之銜接槽201B可採用與前述定位槽201A、貫槽310相同的固定方式。亦即,連接裝置200之連接部210的形狀可配合驅動桿500底部之內壁形狀,且銜接槽201B與嵌合槽510的位置也是對應的,可透過穿置方式將兩者相固定。Referring to FIG. 5 and FIG. 6 in conjunction with FIGS. 1 and 2, the present invention can also be implemented in the overall manner of the pneumatic hammer structure 100. For example, the pneumatic hammer structure 100 can be coupled to the drive rod 500 of the external drive source, and one side (bottom) of the drive rod 500 has two engagement slots 510. In contrast, the connection device 200 can have two engagement slots. 201B can also be disposed on the surface 201 of the connecting portion 210. The orientation of the engaging groove 201B and the positioning groove 201A at the connecting portion 210 may be the same or different. The fitting groove 510 of the driving rod 500 and the engaging groove 201B of the connecting device 200 can be fixed in the same manner as the positioning groove 201A and the through groove 310. That is, the shape of the connecting portion 210 of the connecting device 200 can match the shape of the inner wall of the bottom of the driving rod 500, and the positions of the engaging groove 201B and the fitting groove 510 also correspond to each other, and can be fixed by the wearing method.
驅動桿500之頂部用於連接氣動裝置(通常為怪手等機具),空氣由連接裝置200的通氣孔202導入,再經由組接部230、組接端610灌入本體600。當氣動錘結構100被驅動時,驅動桿500一邊旋轉鑽入地面,同時以氣體驅動末端的本體600衝擊岩層。於上述過程中,外殼300以及本體600皆透過連接裝置200而間接被驅動桿500旋轉帶動。The top of the driving rod 500 is used to connect a pneumatic device (usually a machine such as a strange hand), and air is introduced from the vent hole 202 of the connecting device 200, and then injected into the body 600 via the assembly portion 230 and the assembly end 610. When the pneumatic hammer structure 100 is driven, the drive rod 500 is rotatably drilled into the ground while the rock body is struck by the gas-driven end body 600. In the above process, the outer casing 300 and the body 600 are indirectly driven by the driving rod 500 through the connecting device 200.
在此設置下,連接裝置200的組接部230僅需承受組接段610反饋的扭矩以及來自岩層的正向衝擊力,而外殼300之重力及來自外側岩層的周向扭矩將被傳遞至連接裝置200以及驅動桿500。With this arrangement, the assembly 230 of the connecting device 200 only has to withstand the torque fed back by the assembly segment 610 and the positive impact force from the formation, while the gravity of the outer casing 300 and the circumferential torque from the outer formation are transmitted to the connection. Device 200 and drive rod 500.
因此,氣動錘結構100在施作之過程中,連接裝置200的應力分布可被有效地平均化,不容易造成局部負荷過載之破壞現象。Therefore, during the application of the pneumatic hammer structure 100, the stress distribution of the connecting device 200 can be effectively averaged, and the damage of the local load overload is not easily caused.
本新型在上文中已以較佳實施例揭露,然熟習本項技術者應理解的是,該實施例僅用於描繪本新型,而不應解讀為限制本新型之範圍。應注意的是,舉凡與該實施例等效之變化與置換,均應設為涵蓋於本新型之範疇內。因此,本新型之保護範圍當以申請專利範圍所界定者為準。The present invention has been described in the above preferred embodiments, and it should be understood by those skilled in the art that the present invention is not intended to limit the scope of the present invention. It should be noted that variations and permutations equivalent to those of the embodiments are intended to be within the scope of the present invention. Therefore, the scope of protection of this new type is subject to the definition of the scope of patent application.
