Definitions
- Hydraulic rescue device for manual operation by a rescue person
- the invention relates to a hydraulic rescue device for manual operation or use by at least one rescue person.
- the hydraulic rescue device is manually portable or positionable by the rescuer.
- Such a hydraulic rescue device comprises a hydraulic cylinder with a cylinder tube and at least one adjustable relative to the cylinder tube piston rod.
- At least one first supporting surface formed on the cylinder tube is provided for load-transmitting support of the rescue device to first object surfaces which can be freely selected by a rescue person.
- At least one second supporting surface formed on the at least one piston rod is provided for the load-transmitting support of the rescue device on a second object surface, for example a vehicle body or another object, which can be freely selected by a rescue person.
- At least one manually operable control valve serves for the demand-initiated initiation and termination of adjustment movements of the at least one piston rod relative to the cylinder tube.
- Such hydraulic rescue devices are predominantly used by technical assistance services or by other aid organizations, such as fire brigades, in order to be able to rescue injured persons from deformed vehicles or from other trapped or trapped situations.
- such rescue devices are used to impose jammed doors or raise other disturbing objects in the area of the accident victim or push away. This makes it possible in many cases to get trapped or trapped persons free or to create sufficient space in the vicinity of the accident victim to a salvage from the respective environment, such as a passenger compartment of a car or truck, from a building structure , or the like, to achieve.
- massive hydraulic actuating cylinders are required and sufficiently large hydraulic docking forces are required in order to be able to apply the respective actuating forces.
- the object of the present invention is to further develop a generic hydraulic rescue device in such a way that it supports and / or achieves the fastest possible and efficient or targeted rescue of accident victims.
- An inventive hydraulic rescue device comprises on the lateral surface of the at least one piston rod at least one readable by a rescuer marking which markings or markings at least to signal a still available residual stroke and / or signaling the already set Stellhubes at least one piston rod against the Cylinder tube is provided or are.
- An advantage of the hydraulic rescue device according to the invention is that rescue operations can thus be carried out in a particularly targeted or efficient manner.
- the markings that can be read and interpreted by the rescuer make it possible to take due account of the technical limitation of the rescue device in good time or early.
- the rescuer can implement the corresponding rescue cylinder early or set at a more suitable position to create the required rescue opening or the required space to rescue the corresponding accident victim person. Valuable time in the course of a rescue operation of injured persons can thereby be saved.
- errors or misjudgements of the rescue person can be held back. For example, there may be no irritation if the hydraulic rescue cylinder is already at maximum but the rescuer is of the belief that another maneuver would still be available.
- the markings on the at least one piston rod comprise dimensions, in particular numerical values and / or units of measure, which give dimensions to the residual stroke of the at least one piston rod still available.
- the rescue person can take early or timely measures, for example, repositioning the rescue device or attach intermediate elements or extension parts to speed up the rescue process or complete.
- the markings comprise arrow-shaped, bar-shaped or wedge-shaped symbols, which symbols represent the still available residual stroke of the at least one piston rod.
- the markings for value or amount signaling of the remaining available stroke of the at least one piston rod and / or the value or amount signaling the respective set Stellhube s the at least one piston rod with respect to the first Abstütz- surface on the cylinder tube intended.
- This also allows the rescue person to gain an overview of which remaining path or which travel is still available to quickly complete the rescue operation or to effect the corresponding rescue opening. If the set travel distance is displayed in each case, the remaining travel still remaining can be simply determined or evaluated by the rescue person in connection with the maximum available travel stroke.
- the specified measures result in better planning of a rescue operation, after the rescue person is signaled in plain text and / or symbolically, which lift or pusher reserve is still available.
- the markings comprise marking rings or line markings running at least partially over the cross-sectional or circumferential circumference of the at least one piston rod. It is advantageous that such markings can be made easily and quickly and give these labels a clear information about the respective work or system state of the hydraulic rescue device. In addition, starting from almost all viewing directions with respect to the rescue device or on the at least one piston rod, the respective status information can be clearly detected.
- the corresponding marking can also be detected from virtually all viewing directions or read by the rescue person without requiring any changes in the position of the rescue device and / or the rescuer.
- the respective information can thus be well captured from almost all viewing directions.
- cost-intensive or the surface of the at least one piston rod may possibly be impaired. ing markings are avoided. In particular, this allows excessive processing to be kept back or costs-causing marking steps to be kept in an optimal cost and benefit ratio.
- a plurality of spaced-apart markings are formed with respect to the longitudinal axis of the at least one piston rod.
- the rescuer can learn the remaining available stroke relatively early or timely.
- a quasi-continuous or accompanying information during use of the hydraulic rescue device is thus available for the rescuer.
- markings which are executed only in the last end portion of the at least one piston rod, thereby the appropriate rescue operation can be carried out particularly targeted and thoughtful or efficient, especially the appropriate use of the hydraulic rescue device can be planned exactly.
- a good readability and avoidance of leaks in the course of using the hydraulic rescue device is achieved when the markers are formed by characters, symbols and / or value information, which are designed to contrast in color and flush with the surface of the at least one piston rod.
- the markers are formed by characters, symbols and / or value information, which are designed to contrast in color and flush with the surface of the at least one piston rod.
- embossing or stamping notches in the surface of the at least one piston rod it is thus possible without any problems to achieve high tightnesses or to avoid leaks.
- the formation of an excessive oil film on the lateral surface or surface of the at least one piston rod can thereby be prevented.
- a practicable measure is to form the markers by tempering colors, which tempering colors are applied by thermal effects on metallic Ob er primaab sections of at least one piston rod, in particular produced by a laser beam machining.
- the corresponding markings relatively inexpensively and quickly in the respective Ob erphilab sections of the piston rods are introduced.
- an economic development of the respective markings is thereby achievable.
- it is also given a long-term durability or high durability of the corresponding markings, without thereby affecting the corresponding Ervidab sections of at least one piston rod would be affected.
- an alternative labeling measure after which the markings are applied by electrochemical, in particular galvanic processing methods on metallic Ob er primaab sections of at least one piston rod.

- This makes it possible to create an optimized ratio between performance and light weight or effortless handling.
- a variety of typically occurring rescue scenarios, especially in connection with vehicle accidents, can be covered.
- an optimized relationship between clarity and information content or information depth is achieved when the markers are arranged at a distance of 50 to 100 mm.
- this provides an operator with sufficient information about which thrust effects can still be achieved with the hydraulic rescue device.
- this creates an optimized relationship between labeling effort and sufficient information content for the individual rescuer.
- the at least one piston rod is provided with a comparatively higher arrangement density of markings or a comparatively higher distance resolution for the remaining remaining stroke compared to the initial subsection of the total available setting stroke.
- this gives a higher resolution of the final distance compared to the initial distance.
