摘要： There is described a securing device for releasably securing a first object to a second objection. The device comprises a casing and a coupling magnet housed in the casing. The casing is configured for being inserted in a passageway formed by aligned openings of the first and second objects when assembled together, for blocking separation of the first object and the second object from one another. The coupling magnet is moveable from an initial position to a working position to form a magnetic coupling for holding the casing in the passageway. The first and second objects can respectively be a tooth of a mining or excavation bucket and an adaptor of the bucket for the tooth. A fixed magnet can be provided in the casing, the fixed magnet being oppositely poled with respect to the coupling magnet for damping the movement of the coupling magnet to its working position. There is also provided a removal tool for removal of the securing device from its securing position. The removal tool includes a coupling magnet for being moved from a retracted position to a coupling position for magnetically coupling with the securing device for releasing the coupling magnet of the securing device from its working position and withdrawal of the securing device.

摘要： There is described a securing device (10) for releasably securing a first object to a second objection. The device comprises a casing (12) and a coupling magnet (22) housed in the casing. The casing is configured for being inserted in a passageway formed by aligned openings (54, 60) of the first and second objects when assembled together, for blocking separation of the first object and the second object from one another. The coupling magnet (22) is moveable from an initial position to a working position to form a magnetic coupling for holding the casing in the passageway. The first and second objects can respectively be a tooth (50) of a mining or excavation bucket and an adaptor (52) of the bucket for the tooth (50). A fixed magnet (28) can be provided in the casing (12), the fixed magnet (28) being oppositely poled with respect to the coupling magnet (22) for damping the movement of the coupling magnet to its working position. There is also provided a removal tool (178) for removal of the securing device from its securing position. The removal tool includes a coupling magnet (180) for being moved from a retracted position to a coupling position for magnetically coupling with the securing device (10) for releasing the coupling magnet (22) of the securing device from its working position and withdrawal of the securing device.

摘要： There is described a securing device (300) for releasably securing a first object to a second object, the device comprising a casing (12) having a top end (304) and a bottom end (310), and at least one magnet (22) housed within the casing. The casing is configured for being inserted in a passageway formed by aligned openings of the first and second objects when assembled together whereby the casing blocks separation of the first object and the second object from one another. The magnet is automatically movable along the casing (12) to a working position from an initial position within the casing by magnetic attraction to form a magnetic coupling for holding the casing in position when the casing is located in the passageway formed by the aligned openings of the first and second objects. A peripheral wall of the casing (12) surrounds the magnet and the magnet is retained captive within the casing so as to be restricted to movement between the initial and working positions of the magnet, the casing being of a magnetically attracted material. In embodiments of the disclosure, the magnet (22) is radially distanced from the casing by an essentially non-magnetically attracted material (302, 302a, 302b), and the magnet is typically arranged for returning to its initial position upon being withdrawn from the magnetic coupling to allow for removal of the casing from the passageway and thereby separation of the first and second objects. The securing device has particular application to securing machinery components together and in particular, ground engagement components. Methods for use of the securing device are also described.
