Abstract
A device for clamping an element includes a pressure chamber having a flexible wall section with an elastic jacket and a rigid wall section that acts as a counter-bearing. The jacket is provided with a contact surface to connect with the element.
Claims27
A clamp configured to be movably fastened to a carriage for a horizontal ground drilling device having a framework on which the ground drilling device may be arranged at start-up or in operation, comprising:
- a flexible section comprising an elastic jacket including a contact surface for contacting a housing of a percussion drilling device to be clamped, wherein the contact surface of the elastic jacket is adaptable to form a frictional connection with the housings of percussion drilling devices of different shapes and sizes;
- a tubular rigid wall section;
- a planar sealing element within the tubular rigid wall section;
- and
- a radial force element coupled to the flexible section, said radial force element configured to form a pressure-tight connection between the elastic jacket and the rigid wall section;
- wherein the flexible section is coupled to the rigid wall section to form a pressure chamber, and wherein the rigid wall section acts as a counter-bearing to said flexible section when a pressure medium is supplied to said pressure chamber to form a frictional connection between the elastic jacket and the housing of the percussion drilling device to be clamped;
- and
- wherein a circumferential edge of the sealing element contacts one of the elastic jacket or the rigid wall within the tubular rigid wall section.

A carriage for a horizontal ground drilling device having a framework on which the ground drilling device may be arranged at start-up or in operation including:
- a device for clamping a housing of a percussion drilling device of the horizontal ground drilling device, the device for clamping being movably fastened to the carriage, comprising:
- a tubular rigid wall section;
- a planar sealing element within the tubular rigid wall section;
- and
- a flexible section coupled to an interior of the tubular rigid wall section to form a pressure chamber, said flexible section comprising an elastic jacket including a contact surface for contacting the ground drilling device to be clamped, wherein the contact surface of the elastic jacket is adaptable to form a frictional connection with housings of percussion drilling devices of different shapes and sizes to be clamped;
- wherein a circumferential edge of the sealing element contacts one of the elastic jacket or the rigid wall within the tubular rigid wall section;
- and
- wherein said rigid wall section acts as a counter-bearing to said flexible section and said elastic jacket is configured to move inward relative to the rigid wall section as a pressure medium is supplied to the pressure chamber to form a frictional connection between the elastic jacket and the ground drilling device to be clamped.

A method for clamping a horizontal ground drilling device to a carriage having a framework on which the ground drilling device may be arranged at start-up or in operation comprising:
- providing a device for clamping a housing of a percussion drilling device of the horizontal ground drilling device, the device for clamping being movably fastened to the carriage, including:
- a tubular rigid wall section;
- and
- a flexible section coupled to an interior of the tubular rigid wall section to form a pressure chamber, said flexible section comprising an elastic jacket including a contact surface for contacting the percussion drilling device to be clamped, wherein the contact surface of the elastic jacket is adaptable to form a frictional connection with the housing of percussion drilling devices of different shapes and sizes;
- wherein said rigid wall section acts as a counter-bearing to said flexible section and said elastic jacket is configured to move inward relative to the rigid wall section as a pressure medium is supplied to the pressure chamber;
- inserting a portion of the percussion drilling device into the clamp;
- and
- supplying the pressure medium to the pressure chamber to cause said elastic jacket to move inward to form the frictional connection between the contact surface of the elastic jacket and the portion of the percussion drilling device within the clamp.
