Embodiment Construction

[0024] Such as figure 1 and figure 2 As shown, the cylinder device 1 comprises a foot 13 , a housing 2 , a piston rod 3 and a cylinder head 7 .

[0025] If such a cylinder device 1 is used in a lifting device for a chassis of a mobile device, usually several (ie usually 4) such cylinder devices 1 are used. The cylinder device 1 is usually installed on the chassis of the mobile device in such a manner that the end of the cylinder device 1 at the cylinder head faces upward. Therefore, the end of the leg-side cylinder device 1 is downward, that is, toward the ground. Usually, the cylinder device 1 is mounted near the castors (not shown) of the chassis, or is directly integrated into the castors. In particular, such mobile devices may be medical devices, such as surgical robots.

[0026] Such as figure 1 and figure 2 As shown, the upper end of the housing 2 is connected to the cylinder head 7 . For example, the cylinder head 7 can be fixed on the housing 2 by screws. The...

Abstract

The invention relates to a cylinder device for a hydraulic lifting device 1, which has a housing 2 and a piston rod 3 axially movable relative to the housing 2. A rotary element 4 is mounted on the housing 2 in such a way that a rotary movement of the rotary element 4 relative to the housing 2 is possible and an axial movement of the rotary element 4 relative to the housing 2 is prevented. The piston rod 3 has a movement transmission element 5, wherein the movement transmission element 5 translates an axial movement of the piston rod 3 into a rotary movement of the rotary element 4. A sensor unit 6 is attached to the housing 2, which detects the rotary movement of the rotary element 4. Furthermore, the invention also relates to a hydraulic lifting device with such a cylinder device 1, a chassis of a mobile device with a lifting device and a mobile device with a chassis.

Description

technical field [0001] The invention relates to a cylinder device for a hydraulic lifting device, a hydraulic lifting device with such a cylinder device, a chassis with a hydraulic lifting device and a mobile device with a chassis. In particular, the mobile device may be a mobile medical device. Background technique [0002] Chassis of mobile devices are known from the prior art. In particular, use on mobile medical devices, for example on surgical robots or operating tables, places special demands on the chassis. Such mobile devices must be securely secured, supported and leveled during use, regardless of the ground. A hydraulic lifting device on the chassis, also known as a "floor lock" system, can be used for this purpose, as shown for example in DE 10 2012 001 555 A1. [0003] Typically, a cylinder arrangement for the hydraulic lifting device is provided on or assigned to each castor of the chassis. Hydraulic fluid is forced from a reservoir via a conduction system i...
