Abstract

The coupling socket for connection of a threaded rock bolt (1) to a striking rock drilling machine (2) comprises a first part (3) with an inner thread for connection of the bolt (1) and a second part (5) with an inner thread for connection of the drilling machine. The second part comprises a lock arrangement (7) running across a longitudinal axis (9) of the coupling socket. The lock device works in conjunction with an area (8) on the drilling machine to prevent the coupling socket and the drilling machine being separated.

Description

Manguito de acoplamiento para conectar un perno de anclaje roscado a una perforadora de rocas por impactos.Coupling sleeve to connect a bolt threaded anchor to a rock drill by impacts.

La presente invención se refiere a un manguito de acoplamiento para la conexión de un perno de anclaje roscado para una perforadora de rocas por impactos. Más específicamente la invención se refiere a un diseño específico del manguito de acoplamiento que asegura que una determinada de las dos conexiones roscadas del manguito de acoplamiento se suelte primero cuando la perforadora de rocas es desconectada del perno de anclaje.The present invention relates to a sleeve coupling for connecting a threaded anchor bolt for a rock drill by impacts. More specifically the invention refers to a specific sleeve design of coupling that ensures that a certain of the two connections threaded coupling sleeve is released first when the Rock drill is disconnected from the anchor bolt.

En una solución previamente conocida para asegurar que una determinada conexión roscada se suelte primero, véase SE 433 097, se usan roscas con diferentes pasos para conseguir una conexión roscada que es sustancialmente más difícil de soltar que la otra. Estas soluciones tienen el inconveniente de que se deben usar piezas no estándares. Se debe controlar constantemente qué extremo es cual para conseguir una conexión correcta.In a previously known solution for ensure that a certain threaded connection is released first, see SE 433 097, threads with different steps are used to achieve a threaded connection that is substantially more difficult Let go of the other. These solutions have the disadvantage of that non-standard parts should be used. It must be controlled constantly which end is which to get a connection correct.

En un intento por resolver el problema anteriormente mencionado, véase WO 02/057591, un manguito es agarrado en la rosca para que deba ser difícil de soltar. Resultó que esta solución tiene el inconveniente de que no puede asumir las cargas de las ondas de choque a las que es sometida la conexión roscada durante la perforación.In an attempt to solve the problem previously mentioned, see WO 02/057591, a sleeve is held on the thread so it should be difficult to release. turned out that this solution has the disadvantage that it cannot assume the loads of the shock waves to which the connection is subjected threaded during drilling.

La presente invención, que es definida en la reivindicación posterior, tienen el objetivo de obviar los inconvenientes anteriormente mencionados proveyendo el manguito de acoplamiento con un dispositivo de bloqueo que coopera con una región en el adaptador del vástago de la perforadora de rocas para evitar que el manguito de acoplamiento y la perforadora de rocas se separen cuando la perforadora de rocas y el perno de anclaje se separen.The present invention, which is defined in the subsequent claim, they have the objective of obviating the drawbacks mentioned above providing the sleeve of coupling with a locking device that cooperates with a region in the rock drill shank adapter for prevent the coupling sleeve and rock drill from separate when the rock drill and anchor bolt are separate

Se describe una forma de realización de la invención abajo con referencia al dibujo anexo donde la Fig. 1 muestra una vista en perspectiva de un manguito de acoplamiento según la invención y un adaptador del vástago y un perno de anclaje para la cooperación con el manguito de acoplamiento. La Fig. 2 muestra una sección a través del dispositivo según la Fig. 1 con el perno de anclaje y la perforadora de rocas conectados al manguito de acoplamiento.An embodiment of the Invention below with reference to the attached drawing where Fig. 1 shows a perspective view of a coupling sleeve according to the invention and a rod adapter and an anchor bolt for cooperation with the coupling sleeve. Fig. 2 shows a section through the device according to Fig. 1 with the anchor bolt and rock drill connected to the sleeve of coupling.

El manguito de acoplamiento mostrado en el dibujo comprende una primera parte 3 provista de una rosca interna 4 a la que se puede conectar un perno de anclaje roscado 1. El perno de anclaje roscado está provisto de una barrena no mostrada para perforar el taladro donde el perno de anclaje debe ser anclado. El manguito de acoplamiento comprende también una segunda parte 5 provista de una rosca interna 6 a la que se puede conectar una perforadora de rocas 2. En el dibujo se muestra el adaptador del vástago perteneciente a la perforadora de rocas. El manguito de acoplamiento tiene un eje longitudinal 9. El manguito de acoplamiento está provisto en su segunda parte 5 de dos orificios 10 dispuestos transversalmente al eje 9 donde se dispone un dispositivo de bloqueo 7 en forman de dos pasadores por resorte. El dispositivo de bloqueo 7 coopera con una región 8 para evitar que el manguito de acoplamiento y la perforadora de rocas 2 se separen.The coupling sleeve shown in the drawing comprises a first part 3 provided with an internal thread 4 to which a threaded anchor bolt 1 can be connected. The threaded anchor bolt is provided with a auger not shown to drill the hole where the anchor bolt should be anchored. The coupling sleeve also comprises a second part 5 provided with an internal thread 6 to which it can be connected a rock drill 2. The drawing shows the adapter of the stem belonging to the rock drill. The sleeve of coupling has a longitudinal axis 9. The sleeve of coupling is provided in its second part 5 with two holes 10 arranged transversely to axis 9 where a locking device 7 in the form of two spring pins. He locking device 7 cooperates with a region 8 to prevent the  coupling sleeve and rock drill 2 se separate

Cuando se ajusta un perno de anclaje 1 el adaptador del vástago de la perforadora de rocas 2 gira a medida que es sometida a impactos. A través de esto se perfora un taladro con el perno de anclaje 1, taladro en el cual se debe anclar el perno de anclaje. Durante la perforación se desbloquea el dispositivo de bloqueo 7. Después de la perforación el perno de anclaje 1 debe ser separado del manguito de acoplamiento y dejado en la roca. Por este medio la perforadora de rocas gira para soltarse de la conexión roscada. Gracias a la cooperación entre el dispositivo de bloqueo 7 y la región 8 que tiene un diámetro más pequeño que la rosca del adaptador del vástago se evita que la perforadora de rocas 2 y el manguito de acoplamiento se separen. Después de esto el taladro es llenado alrededor del perno de anclaje con cemento o resina para el anclaje del perno de anclaje en el taladro.When an anchor bolt 1 is adjusted the rock drill stem 2 adapter rotates custom which is subjected to impacts. Through this a drill is drilled with anchor bolt 1, a hole in which the anchor bolt During drilling, the locking device 7. After drilling the bolt anchor 1 must be separated from the coupling sleeve and left on the rock By this means the rock drill rotates to Release the threaded connection. Thanks to the cooperation between the locking device 7 and region 8 having a diameter more small than the thread of the stem adapter prevents the Rock drill 2 and coupling sleeve separate. After this the drill is filled around the bolt of anchor with cement or resin for anchoring anchor bolt in the drill.
