Description

[0001] The invention relates to a sliding system for sliding an element on a support according to claim 1, a method for sliding an element on a support according to claim 13 and the use of the sliding system for moving a bridge component according to claim 15.

[0002] Hydraulic systems are known for moving heavy loads, in which a cylinder is moved by means of hydraulic fluid supplied by a hydraulic pump in order to provide a particularly large force or high pressure.

[0003] The larger the load to be moved, the greater the force against which a hydraulic system is supported must be to prevent the hydraulic system from shifting away from the load.

[0004] Against this background, one objective of the presented invention is to provide a compact hydraulic system that enables the sliding of bridge components.

[0005] The main features of the invention are specified in claims 1, 13 and 15. Embodiments of the invention are the subject of claims 2 to 12 and 14.

[0006] Following a first aspect of the presented invention, a sliding system for sliding an element on a carrier is presented.

[0007] The presented sliding system comprises an actuator system, an interface, and a clamping system, wherein the interface is mechanically coupleable to the element, wherein the actuator system is configured to push the interface away from the clamping system, wherein the clamping system comprises a base body in which a plurality of receptacles are formed, wherein in each receptacle a clamping element is movably arranged between a first position and a second position, and wherein in each receptacle a hydraulic cylinder is arranged which is supported on the base body and is configured to push a respective clamping element arranged in the receptacle from the first position to the second position.

[0008] The presented invention is based on the principle of using multiple clamping elements to clamp the sliding system's clamping mechanism to a support, such as an H-beam or a rail. This provides multiple, independent clamping points where the clamping system is connected to the support. In particular, the clamping points can operate redundantly or selectively.

[0009] By using multiple clamping elements, it is possible to retighten the various clamping elements by first clamping a first clamping element with a first clamping force, then clamping another, particularly an adjacent, clamping element with a second clamping force, and finally clamping the first clamping element with a third clamping force that is greater than the first clamping force or, if applicable, greater than the second clamping force. Accordingly, the entire clamping system can be clamped to the beam with a particularly high clamping force, enabling the presented sliding system to move particularly heavy elements.

[0010] Furthermore, the numerous clamping elements allow the clamping system to be clamped to a beam in specific areas, so that, for example, the clamping system can be clamped around a bolt without clamping at the bolt's position. Accordingly, the clamping system can be freely positioned on the beam, and a sliding element can always be subjected to maximum force.

[0011] In an exemplary embodiment, the clamping system comprises five clamping elements and correspondingly five receptacles as well as five hydraulic cylinders, whereby the number of clamping elements, receptacles and hydraulic cylinders can of course be varied depending on requirements.

[0012] The interface provided according to the invention can, for example, be a metal plate which has receptacles for screws for screwing the interface to a sliding element.

[0013] The base body provided according to the invention consists, for example, of steel and forms a plurality of receptacles in which the clamping elements are movably arranged. In particular, the base body is placed on a respective support so that the clamping elements are movably mounted above the support and only contact the support with their clamping areas.

[0014] The base body can form a counter-clamping area with which it overlaps or engages a respective support, so that the clamping elements contact the support on one side and the base body contacts the support on the opposite side. The clamping elements then pull the base body against the second side and clamp it to the support.

[0015] In particular, the base body forms mounting plates on which the hydraulic cylinders are arranged. These are both particularly stable and spaced away from the respective walls of the receptacles, so that the clamping elements can be movably mounted between the mounting plates and the walls of the receptacles.

[0016] It can be provided that each clamping element includes a clamping area which is spaced away from the support in the first position and contacts the support in the second position.

[0017] The hydraulic cylinders provided according to the invention are arranged on the base body and are in particular surrounded by a respective clamping element or arranged in a space surrounded by a clamping element. Accordingly, when activated and extended, a respective hydraulic cylinder presses against a respective clamping element, e.g., against an end of the clamping element opposite the clamping area of ​​the clamping element, and pushes the entire clamping element into its second position.

[0018] Accordingly, the clamping elements can be extended and retracted into the receptacles like a drawer, with the hydraulic cylinders pressing not on the clamping areas, but on correspondingly load-bearing areas of the clamping elements.

[0019] The arrangement of the hydraulic cylinders in a space surrounded by a clamping element makes the presented sliding system particularly compact.

[0020] It may also be provided that a number of flexible clamps are arranged in each clamping area.

[0021] Flexible clamps made of, for example, rubber or another flexible material, adapt their shape to the carrier and maximize the contact area between the clamping system and the carrier.

[0022] It may also be provided that all hydraulic cylinders arranged in the mounts are movable independently of each other.

[0023] Independently movable hydraulic cylinders allow for retightening of the individual clamping elements and optimal adaptation of the clamping system's shape to the geometry of a given support. This maximizes the contact area between the clamping system and the support.

[0024] It may also be provided that each hydraulic cylinder is to be fluid-conductingly coupled to a hydraulic pump via a separate hydraulic line.

[0025] Separate hydraulic lines allow for different or specific pressures in the various hydraulic cylinders, so that each hydraulic cylinder can be activated or operated with the maximum possible pressure for that hydraulic cylinder.

[0026] In particular, separate hydraulic lines allow one clamping element to be released while the remaining clamping elements are still clamped.

[0027] It may also be provided that a separate valve is arranged on each of the separate hydraulic lines, through which a flow of hydraulic fluid from the hydraulic pump into a respective hydraulic line can be adjusted.

[0028] Separate hydraulic valves allow a central hydraulic pump to be used to operate the presented sliding system.

[0029] It may also be provided that a separate check valve is arranged on each of the separate hydraulic lines, configured to block a flow of hydraulic fluid from the clamping system back into a respective hydraulic line in a blocking position and to release a flow of hydraulic fluid from the clamping system back into a respective hydraulic line in a releasing position.

[0030] Separate check valves allow each hydraulic cylinder to be released separately, while the remaining clamping elements are still engaged.

[0031] It may also be provided that each clamping element has a mechanism configured to move the clamping element from the second position to the first position.

[0032] In particular, the mechanism may include a threaded spindle and a pressure plate.

[0033] A threaded spindle, such as a trapezoidal threaded spindle, exhibits high friction. This means that, in the standard thread range, the threaded spindle is self-locking and has the advantage that it does not need to be additionally secured in its rest position.

[0034] Furthermore, a high force can be provided via a threaded spindle to push a hydraulic cylinder back into its starting position. For example, the threaded spindle can be connected to a machine via an interface, such as a polygon, to rotate it quickly and with great force.

[0035] It may also be provided that the mechanism forms at least at one end of the respective clamping element a number of stop elements which are configured to provide a continuously increasing counterforce to a force moving the clamping element upon contact with the base body.

[0036] Stop elements, such as mechanical spring elements or flexible stops made of, for example, rubber, provide feedback to a user upon contact with a stop, thus preventing damage to the clamping system from over-tightening the mechanism.

[0037] It may also be provided that each hydraulic cylinder is configured to push a respective clamping element into the second position with a pressure between 10 tonnes and 50 tonnes, in particular between 30 tonnes and 40 tonnes.

[0038] It may also be provided that a first number of clamping elements are movable in the opposite direction to a second number of clamping elements between the first position and the second position, so that the first number of clamping elements rests against a first side of the beam in the second position and the second number of clamping elements rests against a second side of the beam opposite the first side in the second position.

[0039] Opposing clamping elements distribute a clamping force evenly across both sides of a given support.

[0040] Alternatively, it can be provided that all clamping elements are movable in the same direction between the first position and the second position.

[0041] It may also be provided that friction elements are arranged on each clamping element to maximize static friction between the clamping element and the housing.

[0042] Metal elements made of, for example, hard metal, especially sintered metal, have proven to be particularly suitable friction elements.

[0043] It may also be provided that the actuator system comprises a number of hydraulic cylinders which are arranged at a first end movable about an axis at the interface and at a second end opposite the first end movable about an axis on the clamping system.

[0044] Hydraulic cylinders arranged movably on the clamping system and the interface enable a relative movement of the interface to the clamping system, so that an element connected to the interface can be pushed away from the clamping system.

[0045] It may also be provided that the actuator system includes a number of hydraulic cylinders configured to push the interface away from the clamping system with a pressure between 10 tonnes and 50 tonnes, in particular between 30 tonnes and 40 tonnes.

[0046] According to a second aspect, the presented invention relates to a method for sliding an element onto a carrier.

[0047] The presented method comprises clamping a clamping system of a possible embodiment of the presented sliding system at a first position on the support, connecting an interface of the sliding system with the element, activating the actuator system of the sliding system to push the interface away from the clamping system and to slide the element along the support, and releasing the clamping system from the support.

[0048] It may further be provided that the presented method includes moving the clamping system to a second position on the support, the second position being closer to the element than the first position, clamping the clamping system firmly to the support, and activating the actuator system to push the interface away from the clamping system again and to push the element along the support again.

[0049] According to a third aspect, the presented invention relates to the use of a possible embodiment of the presented sliding system for moving a bridge structure.

[0050] Further features, details and advantages of the invention will become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. The drawings show: Fig. 1 shows a possible embodiment of the presented sliding system, Fig. 2 shows a detailed view of a base body of a clamping system of the sliding system according to Fig. 1 , Fig. 3 a first detailed view of a clamping element of the sliding system according to Fig. 1 , Fig. 4 a second detailed view of the clamping element according to Fig. 3 , Fig. 5 the sliding system according to Fig. 1 in a side view, Fig. 6 the sliding system according to Fig. 5 , while it is arranged on an element to be pushed and on a support, Fig. 7 shows a representation of the presented method.

[0051] In Fig. 1 A sliding system 100 for sliding an element on a support is shown.

[0052] The sliding system 100 comprises an actuator system 101, an interface not shown here and a clamping system 103.

[0053] The actuator system 101 is configured to push the interface and, consequently, an element coupled to the interface away from the clamping system 103.

[0054] The clamping system 103 is configured to clamp the sliding system 100 to a support (not shown here). For this purpose, the clamping system 103 comprises a base body 105 in which a plurality of receptacles 107 are formed.

[0055] In each recording 107, a clamping element 109 is movably arranged between a first position A and a second position B.

[0056] Furthermore, a hydraulic cylinder 111 is arranged in each receptacle 107, which is supported on the base body 105 and is configured to push a respective clamping element 109 arranged in the receptacle 107 from the first position A to the second position B.

[0057] In the first position A, a clamping area 113 of the clamping element 109 is therefore spaced away from the support and in the second position B it is clamped to the support.

[0058] The hydraulic cylinder is pushed back via a threaded spindle 115 and the clamping element 109 is moved into its first position A.

[0059] In Fig. 2 The basic body 105 is shown in detail. It can be seen that the hydraulic cylinders 111 are arranged on support plates 116, which are spaced apart from the walls 117 of the receptacles 107. Accordingly, the clamping elements 109 can engage in recesses 119 formed between the support plates 116 and the walls 117.

[0060] Through an opening 121, an element moving on the threaded spindle 115 can extend out of or into the receptacle 107 in order to move the hydraulic cylinder 111.

[0061] For connecting the actuator system 101, receptacles 123 are provided in which, for example, a bolt can be rotatably mounted.

[0062] In Fig. 3 A part of a clamping element 109 is shown. The clamping element 109 comprises a clamping area 113, a threaded spindle 115 and stop elements 125 in the form of spring pins.

[0063] In Fig. 4 The entire clamping element 109 is shown. It can be seen that friction elements 129 in the form of hard metal plates are arranged on the side walls 127 of the clamping element 109.

[0064] A protective plate 131 protects an inner area 133 of the clamping element 109 from environmental influences when installed.

[0065] In Fig. 5The sliding system 100 is shown in a side view. It can be seen that the clamping system 103 comprises the base body 105 and, by way of example, five clamping elements 109.

[0066] A control unit 135 comprises a hydraulic line for each hydraulic cylinder 111 and corresponding control valves 137 for blocking or releasing a flow of hydraulic fluid to or from the hydraulic cylinders 111.

[0067] In Fig. 6 The sliding system 100 is shown in a state in which four clamping elements 109 are clamped to a support 139 and one clamping element 109 is released. The interface 141, which is coupled to an element 143, such as a bridge component, is also visible. Accordingly, the actuator system 101 pushes the element 143 away from the clamping system 103 when the actuator system 101 is activated.

[0068] In Fig. 7is a method 200 for sliding an element on a support using the sliding system 100 according to Fig. 1 depicted.

[0069] The method 200 comprises a first clamping step 201, in which the clamping system 103 is clamped to a first position on the carrier, a connecting step 203, in which the interface 141 is mechanically coupled to the element 143, a first activation step 205, in which the actuator system 101 is activated, and a release step 207, in which the clamping system 103 is released from the carrier.

[0070] Optionally, the method 100 further includes a movement step 209 in which the clamping system 103 is moved to a second position on the carrier, the second position being closer to the element than the first position, a second clamping step 211 in which the clamping system 103 is clamped at the second position on the carrier, and a second activation step 213 in which the actuator system 103 is activated again to push the interface 141 away from the clamping system 103 again and to push the element 143 along the carrier again.

[0071] The invention is not limited to one of the embodiments described above, but can be modified in many ways.

[0072] However, it can be seen that the invention relates to a sliding system 100 for sliding an element or structure 143 along at least one support 139.

[0073] The sliding system 100 has a clamping system 103, which can be fixed to the support 139 in phases, an interface 141, which can be coupled to the element 143 to be moved, and an actuator system 101, which is arranged between the clamping system 103 and the interface 141 and which is configured and designed to move the interface 141 relative to the clamping system 103 and the support 139. The element 143 to be moved is slidably mounted on the support 139.

[0074] Preferably, the clamping system 103 and the actuator system 101 are arranged and designed such that the interface 141 can be pushed away from the clamping system 103 as soon as the clamping system 103 engages with the carrier 139 for the displacement operation.

[0075] The clamping system 103 has a base body 105 in which a plurality of receptacles 107 are formed, wherein a clamping element 109 is movably arranged in each receptacle 107 between a first position A and a second position B. In the first position A, each clamping element 109 is disengaged from the support 139, so that the clamping system 103, and thus the base body 105, is displaceable relative to the support 139. In the second position B, each clamping element is engaged with the support 139 by force, form, and / or friction, so that the clamping system 109, and thus the base body 105, is fixed to the support 139.

[0076] The clamping elements 109 are actuated by a hydraulic cylinder 111, each hydraulic cylinder 111 being arranged in a receptacle 107. Each hydraulic cylinder 111 is supported against the base body 105 and is configured to push a respective clamping element 109 arranged in the receptacle 107 from the first position A to the second position B.

[0077] If the clamping elements 109 are activated and engaged with the carrier 139, the base body 105 can no longer move relative to the carrier 139. The base body 105 thus provides a stop for the actuator system 101, which is connected to the element 143 to be moved via the interface 141.

[0078] When the actuator system 101, which is formed, for example, by one or more hydraulic cylinders, is activated, the interface 141 is pushed away from the base body 105, which is fixed to the support 139 by means of the clamping system 103, and the element or structure 143 to be moved moves relative to the support 139. The actuator system 101 and its hydraulic cylinders move from a starting position to an end position, whereby the displacement path of the element or structure 143 on the support 139 corresponds approximately to the positioning path of the actuator system 101.

[0079] Once element 143 has reached its new position at the end of the displacement process, the clamping elements 109 of the clamping system 103 are moved from position A to position B. The clamping system 103 and the base body 105 can now move on the support 139. Subsequently, the actuator system 103, specifically its hydraulic cylinder, is moved from its end position to its starting position. During this process, the clamping system 103 and the base body 105 are moved relative to the support 139 towards the structure 143.

[0080] The shift cycle can begin again.

[0081] All features and advantages arising from the claims, the description and the drawing, including design details, spatial arrangements and process steps, can be essential to the invention both individually and in various combinations. Reference symbol list
