Device for transporting, in particular skidding or jacking, a heavy object
The invention relates to a device ( 10 ) for transporting, in particular skidding or jacking, a heavy object ( 4 ) supported on at least one guide ( 2 ), comprising an actuator ( 7 ) for effecting transport, in particular at least one hydraulic cylinder, one end of which is configured for connection to the object ( 4 ) or a foundation and the other end is connected to a shoe ( 8 ) configured for connection to the guide ( 2 ). The shoe ( 8 ) comprises at least two pins ( 11 ) configured to be inserted into openings ( 9 ) in the guide ( 2 ) to provide, at least in the direction of the guide ( 2 ) a positive connection between the shoe ( 8 ) and the guide ( 2 ).
1. Device for transporting a heavy object supported on at least one guide, comprising an actuator for effecting transport one end of which is configured for connection to the heavy object or a foundation and another end of which is connected to a shoe configured for connection to the at least one guide, characterised in that the shoe comprises at least two pins configured to be inserted into openings in the at least one guide to provide, at least in a direction of the at least one guide, a positive connection between the shoe and the at least one guide, and wherein at least one of the pins cooperates with a slidable wedge for adjusting a position of the at least one said pin in a transport direction and/or in a direction opposite to the transport direction.
2. The device according to claim 1 , wherein the pins are separated in the transport direction.
3. The device according to claim 1 , wherein the guide comprises groups of openings corresponding in number and mutual distance to the pins in the shoe.
4. The device according to claim 1 , wherein positions of all of the pins are adjustable in the transport direction and/or in a direction opposite to the transport direction.
5. The device according to claim 1 , wherein the shoe comprises a support frame and the pins are slidably mounted in or on the support frame.
6. The device according to claim 1 , wherein the pins are slidably mounted in pin bearings to enable extending the pins in the openings in the guide to lock the shoe to the guide and retracting the pins from these openings to unlock the shoe from the guide.
7. The device according to claim 6 , wherein the pins are also slidably mounted in or on the shoe to enable adjusting positions of the pins in the transport direction and/or in a direction opposite to the transport direction.
8. The device according to claim 1 , comprising at least one actuator to slide and/or urge the pins to one side of the openings.
9. The device according to claim 1 , wherein the device is configured for skidding or jacking the heavy object and the actuator comprises at least one hydraulic cylinder.
10. The device according to claim 1 , wherein the pins are also slidably mounted in or on the shoe to enable adjusting positions of the pins in the transport direction and/or in a direction opposite to the transport direction.
11. System for transporting a heavy object, comprising at least one guide attached to the heavy object or attached to a foundation, an actuator for effecting transport one end of which is connected to the heavy object or the foundation and another end of which is connected to a shoe which in turn is connected to the at least one guide, characterised in that the shoe comprises at least two pins inserted or insertable into openings in the at least one guide providing, at least in a direction of the at least one guide, a positive connection between the shoe and the at least one guide, and wherein at least one of the pins cooperates with a slidable wedge for adjusting a position of the at least one pin in a transport direction and/or in a direction opposite to the transport direction.
12. The system according to claim 11 , comprising at least one actuator to slide and/or urge the pins to one side of the openings.
13. The system according to claim 11 , wherein the device is configured for skidding or jacking the heavy object and the actuator comprises at least one hydraulic cylinder.
14. The system according to claim 11 , wherein all of the pins are adjustable in the transport direction and/or in a direction opposite to the transport direction.
15. Method of transporting a heavy object supported on at least one guide comprising a series of openings, comprising the steps of:
connecting one end of a device comprising an actuator for effecting transport to the heavy object or a foundation,
connecting another end of the device to the at least one guide by inserting at least two pins from the another end of the device into the openings in the at least one guide, and
extending the actuator to transport the heavy object, wherein at least one of the pins, after inserting the pins in the openings, cooperates with a slidable wedge for adjusting a position of the at least one said pin in a transport direction or in a direction opposite to the transport direction.
16. The method according to claim 15 , wherein the at least one pin is urged to the side of the opening where, during transport, a load is transferred, and locked.
17. The method according to claim 15 , wherein the method is for skidding or jacking the heavy object and the actuator comprises at least one hydraulic cylinder.
