Abstract

The invention relates to a bolt connection with a bearing bolt, in particular for a construction machine, in particular for underground engineering and for a swivel lever, in particular for a construction machine, which connects a first component and a second component pivotably to each other, wherein the bearing bolt extends through at least one first bearing eye on the first component and at least one second bearing eye on the second component, and wherein the bearing bolt can be driven, for releasing the connection, on an exit side out of the first bearing eye and the second bearing eye. At the exit side a protective receptacle is arranged, which is designed to receive and hold the driven-out bearing bolt.

First claim

The invention claimed is:

1. Bolt connection with a single bearing bolt, which connects a first component and a second component pivotably to each other, wherein the bearing bolt extends through at least one first bearing eye on the first component and at least one second bearing eye on the second component, and wherein the bearing bolt, for releasing the connection, can be driven at an exit side out of the first bearing eye and the second bearing eye,
wherein
a protective receptacle is arranged on the exit side, which comprises a housing for preventing the bearing bolt from falling out and is designed to receive and accommodate the driven-out bearing bolt,
an adjusting body is fixed at a front end of the bearing bolt and is arranged in the protective receptacle,
the adjusting body is designed to change the position of the bearing bolt between the bolt connection and the protective receptacle,
the adjusting body is arranged axially with respect to the bearing bolt, and
the housing has an opening through which the adjusting body extends out of the housing of the protective receptacle.

2. Bolt connection according to claim 1 ,
wherein
the bearing bolt is arranged, after release of the connection, in the protective receptacle coaxially to the first bearing eye.

3. Bolt connection according to claim 1 ,
wherein
the bearing bolt is designed as a step bolt and has an area with a smaller diameter, which is formed at a side facing away from the protective receptacle, and has an area with a larger diameter, which is formed at a side facing towards the protective receptacle.

4. Bolt connection according to claim 1 ,
wherein
a position-securing means is arranged on the bolt connection, which can be moved radially to the bearing bolt.

5. Bolt connection according to claim 1 ,
wherein
a position-securing means has a pin lock, which engages in a positive locking way in a recess on the bearing bolt.

6. Bolt connection according to claim 1 ,
wherein
a hydraulic cylinder is arranged on the adjusting body, by means of which the adjusting body can be changed in its position.

7. Bolt connection according to claim 1 ,
wherein
a first position sensor is provided on the bolt connection, which is designed to determine the position of the bearing bolt in the bolt connection.

8. Bolt connection according to claim 1 ,
wherein
a second position sensor is provided on the bolt connection, which is designed to determine a coaxial position of the at least one first bearing eye relative to the at least one second bearing eye.

9. Bolt connection according to claim 8 ,
wherein
the second position sensor is connected to a control module, which is designed to release the bearing bolt, only after a coaxial orientation of the at least one first bearing eye and the at least one second bearing eye, for a movement of the bearing bolt to the bolt connection.

10. Construction machine for underground engineering,
wherein
at least one bolt connection according to claim 1 is provided.

11. Construction machine for underground engineering,
wherein
a mast is pivotably attached to a support device with the at least one bolt connection according to claim 1 is provided.

12. Swivel lever for a construction machine for underground engineering, which is designed to receive actuating cylinders for holding a mast,
wherein
at least one bolt connection according to claim 1 is provided.

13. Bolt connection according to claim 1 ,
wherein
a first area of the bearing bolt has a first diameter,
a second area of the bearing bolt has a second diameter, and
the first diameter is greater than the second diameter.

14. Bolt connection according to claim 13 ,
wherein
a third area of the bearing bolt has a third diameter, and
the second diameter is greater than the third diameter.

15. Bolt connection according to claim 14 ,
wherein
a fourth area of the bearing bolt has a fourth diameter,
the third diameter is the same as the fourth diameter.

16. Bolt connection according to claim 14 ,
wherein
a fourth area of the bearing bolt has a fourth diameter,
the third diameter is greater than the fourth diameter.
