DESCRIÇÃODESCRIPTION
MANGA DE ACOPLAMENTO PARA A CONEXÃO DE UM PERNO DE SEGURANÇA ENROSCADO A UMA PERFURADORA DE ROCHAS PORCOUPLING SLEEVE FOR CONNECTING A FIXED SAFETY PIN TO A ROCK PUNCH BY
IMPACTOS A presente invenção refere-se a uma manga de acoplamento para a conexão de um perno de segurança enroscado a uma perfuradora de rochas por impactos. Mais especificamente a invenção refere-se a um desenho especifico da manga de acoplamento que assegura que uma das duas conexões enroscadas da manga de acoplamento se solte primeiro quando a perfuradora de rochas é desconectada do parafuso de segurança.The present invention relates to a coupling sleeve for connecting a threaded security bolt to an impact rock drill. More specifically the invention relates to a specific design of the coupling sleeve which ensures that one of the two screwed connections of the coupling sleeve is released first when the rock drill is disconnected from the safety screw.
Na solução anteriormente conhecida para assegurar que uma determinada conexão enroscada se solte primeiro, ver o Pedido de Patente SE 433 097, são utilizadas roscas com diferentes passos para conseguir uma conexão enroscada que é substancialmente mais difícil de soltar que a outra. Estas soluções têm o inconveniente de têm de ser utilizadas peças não standardizadas. Constantemente tem que ser verificado que tipo de extremidade é para conseguir uma conexão correcta.In the previously known solution to ensure that a particular threaded connection loosens first, see SE 433 097, threads with different steps are used to achieve a screwed connection which is substantially more difficult to loosen than the other. These solutions have the drawback that non-standard parts have to be used. It constantly has to be verified what kind of end is to achieve a correct connection.
Numa tentativa de resolver o problema anteriormente mencionado, ver Pedido de Patente WO 02/057591, uma manga é agarrada à rosca a qual é muito difícil de se soltar. Resultou que esta solução tem o inconveniente de que não pode assumir as cargas das ondas de choque ás quais a conexão enroscada durante a perfuração é submetida. A presente invenção, que é definida na reivindicação anexa, têm o objectivo de obviar os inconvenientes anteriormente mencionados provendo a manga de acoplamento com um dispositivo de bloqueio que coopera com uma região no adaptador da barra perfuradora de rochas para evitar que a manga de acoplamento e a 1 perfuradora de rochas se separem quando a perfuradora de rochas e o parafuso de segurança são separadas. À continuação é descrita uma forma de realizar a invenção com referência aos desenhos anexos onde a figura 1 é uma vista em perspectiva de uma manga de acoplamento de acordo com a invenção e um adaptador da barra e um parafuso de segurança para cooperarem com a manga de acoplamento. A figura 2 mostra uma secção através do dispositivo de acordo com a figura 1 com o parafuso de segurança e a perfuradora de rochas conectados à manga de acoplamento. A manga de acoplamento mostrada no desenho compreende uma primeira parte 3 provida de uma rosca interna 4 à qual se pode conectar um parafuso de segurança enroscado 1. 0 parafuso de segurança enroscado está provido com uma broca não mostrada para perfurar o furo onde o parafuso de segurança deve ser ancorado. A manga de acoplamento compreende ainda uma segunda parte 5 provida de uma rosca interna 6 à qual a perfuradora de rochas 2 pode ser conectada. No desenho é mostrado o adaptador da barra pertencente à perfuradora de rochas. A manga de acoplamento tem um eixo longitudinal 9. A manga de acoplamento está provida na sua segunda parte 5 com dois orifícios 10 dispostos transversalmente ao longo do eixo 9 onde está disposto um dispositivo de bloqueio 7 com a forma de dois pinos de mola. O dispositivo de bloqueio 7 coopera com uma região 8 para impedir que a manga de acoplamento e a perfuradora de rochas 2 se separem.In an attempt to solve the aforementioned problem, see WO 02/057591, a sleeve is gripped by the thread which is very difficult to release. It turned out that this solution has the drawback that it can not assume the charges of the shockwaves to which the connection twisted during the perforation is subjected. The present invention, which is set forth in the appended claim, is intended to obviate the aforementioned drawbacks by providing the coupling sleeve with a locking device which cooperates with a region in the rock pier bar adapter to prevent the coupling sleeve and the 1 rock drill to separate when the rock drill and the safety screw are separated. In the following there is described one way of carrying out the invention with reference to the accompanying drawings, in which Figure 1 is a perspective view of a coupling sleeve according to the invention and a bar adapter and a securing screw to cooperate with the sleeve of coupling. Figure 2 shows a section through the device according to figure 1 with the safety screw and the rock drill connected to the coupling sleeve. The coupling sleeve shown in the drawing comprises a first part 3 provided with an internal thread 4 to which a screwed safety screw 1 can be connected. The screwed safety screw is provided with a drill not shown to drill the hole where the screw of should be anchored. The coupling sleeve further comprises a second portion 5 provided with an internal thread 6 to which the rock drill 2 can be connected. In the drawing is shown the bar adapter belonging to the rock drill. The coupling sleeve has a longitudinal axis 9. The coupling sleeve is provided in its second part 5 with two holes 10 arranged transversely along the axis 9 where a locking device 7 is disposed in the form of two spring pins. The locking device 7 cooperates with a region 8 to prevent the coupling sleeve and the rock drill 2 from separating.
Quando o parafuso de segurança 1 é ajustado o adaptador da barra da perfuradora de rochas 2 roda à medida que esta é submetida aos impactos. Com esta rotação o furo é perfurado com o parafuso de segurança 1, no qual o parafuso de segurança deve ser ancorado. Durante a perfuração o dispositivo de bloqueio 7 é desbloqueado. Depois da perfuração o parafuso de segurança 1 2 deve ser separado da manga de acoplamento e deixado na roca. Desta maneira a perfuradora de rochas roda para se soltar da conexão enroscada. Graças à cooperação entre o dispositivo de bloqueio 7 e a região 8 que tem um diâmetro mais pequeno que a rosca do adaptador da barra é evitado que a perfuradora de rochas 2 e a manga de acoplamento se separem. Depois disso o furo à volta do parafuso de segurança é cheio com cimento ou resina para ancorar o parafuso de segurança no furo.When the safety screw 1 is adjusted the rock drill rod adapter 2 rotates as it is subjected to impacts. With this rotation the hole is drilled with the safety screw 1, in which the safety screw must be anchored. During drilling the locking device 7 is unlocked. After drilling the safety screw 12 must be separated from the coupling sleeve and left on the rock. In this way the rock drill rotates to release itself from the screwed connection. Thanks to the cooperation between the locking device 7 and the region 8 having a smaller diameter than the thread of the bar adapter, the rock drill 2 and the coupling sleeve are prevented from separating. Thereafter the hole around the locking screw is filled with cement or resin to anchor the locking screw in the hole.
