Definitions
- the invention relates to a self-propelled soil compaction roller that travels in and against a forward direction over a floor during work.
- Generic soil compaction rollers are in particular light compaction rollers, for example in the order of up to 5 t.
- Such machines are used for example in road and path construction, especially for smaller jobs or in confined spaces. They typically have a machine frame, including an articulated one, a drive motor, driving devices, such as, for example, roll bandages and / or rubber wheels, and a machine frame carried by the driving devices, the machine frame representing the essential supporting structure.
- Part of such soil compaction rollers is a body forming the outer surface of the soil compaction roller.
- the body is understood to mean the entire structure of the soil compacting roller which is carried by driving devices and forms the outer surface and which, for example, can also at least partially include the machine frame.
- the body in the present case is understood to mean all components of the soil compacting roller which form the outer surface with the exception of the driving devices of the machine or which are visible from the outside of the machine, in particular when the machine is ready for work and stands on the ground.
- gas-powered drive motors In generic, light soil compaction rollers, it is possible that these comprise a gas-powered drive motor. Such engines therefore use liquefied petroleum gas for the combustion process. Gas-powered drive motors are particularly low in pollutants and therefore environmentally friendly and are therefore also suitable for use in closed rooms, for example. In addition, due to the reduced exhaust gases, they are particularly suitable for use in narrow conditions in which other people are in the vicinity of the soil compacting roller, such as excavation pits or trenches. It is now provided that commercially available, standardized gas containers, for example essentially cylindrical gas bottles, are used to supply these drive motors with liquid gas, which can be exchanged quickly and easily on the construction site.
- the gas used is preferably a liquid gas, for example LPG (liquefied petroleum gas).
- Other drive gases suitable for gas powered drive motors are also considered.
- the soil compaction rollers comprise a front body and a rear body, which are connected via an articulated joint, although other designs, for example with a rigid machine frame, are also possible.
- the generic soil compaction rollers furthermore have at least one front and at least one rear driving device, at least one of the driving devices or both the front and the rear driving device being driven directly or indirectly by the drive motor.
- an indirect drive use is preferably made of a hydraulic pump of a hydraulic system which is driven directly by the drive motor or the primary unit and which in particular drives a hydraulic motor seated on one of the driving devices or a plurality of such hydraulic motors.
- the driving devices are, for example, roller bandages, for example smooth bandages, polygon bands or crusher bandages, or for example also wheels, in particular rubber wheels, in particular a large number of rubber wheels arranged coaxially next to one another in a manner known per se in the prior art.
- the front and the rear driving device can also be designed differently, for example as a combination of a front roller drum and rear wheels.
- a container stowage device for receiving a gas container is present in a self-propelled soil compaction roller mentioned above, the container stowage device comprising a gas storage drawer, which together with the gas container between a stowed position in which the gas container is mounted inside the outer surface of the soil compaction roller formed by the body, and a maintenance position in which the gas container is at least partially outside of this outer surface is adjustable.
- the drawer is designed to hold the gas container, in particular a commercially available gas bottle. It can be moved together with the gas container between the stowage position and the maintenance position.
- the maintenance position describes a position in which the gas container is accessible to an operator from the outside or is at least partially exposed to the outside.
- the gas container in the maintenance position, can be removed from or out of the drawer and the soil compacting roller or can be attached to the drawer.
- the maintenance position is used, for example, to replace an empty gas container with a full one or to gain general access to the gas container.
- the drawer, and with it the gas container was moved into the soil compacting roller, so that the gas container is located inside the machine, in particular inside the outer surface of the machine.
- the gas container In the stowed position, the gas container is therefore protected by the machine components surrounding it and adjacent to it, for example from collisions with obstacles or from unauthorized access.
- the gas container is not or only slightly visible from the outside through the drawer opening, which improves the overall visual impression of the soil compaction roller.
- the stowed position therefore also designates that position of the drawer with the gas container which it is to hold reliably when the soil compacting roller is in operation.
- the gas container and the drawer are thus moved or adjusted together relative to the rest of the soil compaction roller.
- the drawer can be arranged in different ways on the soil compacting roller and can be pulled out in basically any direction.
- the container stowing device is designed such that the drawer can be displaced linearly essentially horizontally and / or perpendicularly to the forward direction between the stowed position and the maintenance position.
- the drawer is moved laterally with respect to the forward direction of the soil compacting roller out of the soil compacting roller or into it.
- the direction of movement of the drawer is therefore essentially parallel to the axis of rotation of the front and / or rear driving device.
- the container stowing device is preferably designed such that the drawer is adjusted between the stowed position and the maintenance position exclusively by means of a linear displacement in the horizontal.
- the adjustment between the stowed position and the maintenance position is particularly simple and does not require any major effort by an operator in both directions.
- a drawer opening is necessarily present in the outer surface formed by the body.
- This drawer opening can basically remain unlocked, i.e. open, so that the gas container is visible from the outside, for example, through the drawer opening.
- the body then runs by definition via this drawer opening from the adjacent wall areas.
- the container stowing device has a cover closing the drawer opening, which in the closed state forms part of the outer surface of the soil compacting roller formed by the body and, in particular in the closed state, is essentially flush with the outer wall regions of the body adjacent to the drawer opening , so that overall an aesthetically appealing uniform outer surface is obtained across the cover and the adjacent outer wall area.
- the lid closes the drawer opening from the outside, in particular when the drawer with the gas container is in the stowed position.
- the cover can be designed, for example, as a flap, so that it can be pivoted about an axis, in particular parallel to the forward direction.
- the lid is panned. This has the advantage that when the gas container is serviced and or when the lid is changed to the horizontal sides, it is not in the way.
- the lid can either be fixed to the drawer or separately from it and / or relatively adjustable to this.
- the cover it is possible for the cover to be designed to be linearly displaceable together with the drawer if, for example, the cover is exclusively and directly attached to the drawer.
- the movements of the lid and the drawer it is also possible for the movements of the lid and the drawer to be independent of one another.
- the lid can be opened outwards and then, in a second step, the drawer can be pulled outwards while the lid remains in its opened position.
- the lid and the drawer are different and adjustable relative to each other, but at the same time are coupled to one another. If the lid is opened, a pull-out movement of the drawer can be triggered, for example.
- the lid closes the drawer opening when the drawer is in the stowed position.
- the lid thus forms part of the outer surface of the soil compacting roller or part of the body, so that the gas container and in particular also the drawer are arranged continuously inside the outer surface of the soil compacting roller. In this way, the gas container is no longer visible from the outside when the lid is closed.
- the cover can be equipped with a lock, so that the cover is lockable. In this way, effective protection against vandalism can be obtained, for example.
- the container stowing device has a locking device for the drawer which releasably locks the drawer in the stowed position and / or in the maintenance position.
- a locking device for the drawer which releasably locks the drawer in the stowed position and / or in the maintenance position.
- a, in particular gravity-dependent, locking device can be provided, which engages when the drawer is pulled completely out of the soil compacting roller and into the maintenance position.
- snaps, locking bolts, clamping devices, positive locking devices or comparable, preferably purely mechanical, locking devices can be used.
- the locking device then prevents the drawer from moving unintentionally from the maintenance position towards the stowed position. In this way, an operator can, for example, change the gas container without running the risk of the drawer sliding away unexpectedly.
- the container stowing device has a, in particular elastically designed, locking element, which is arranged between the lid and the drawer, and which is clamped between the lid and the drawer when the lid is closed so that it Drawer locked in its position, especially the stowage position.
- the locking element can be made of rubber, for example. It is in particular designed, for example, in the form of a cone, a cylinder or a ball. It can be arranged directly on the drawer or directly on the lid. For example, the locking element is arranged on the drawer and protrudes slightly above the drawer in the direction of the lid. If the lid is closed when the drawer is in the stowed position, the lid is pressed against the locking element.
- the elastic locking element is preferably dimensioned such that it is at least somewhat compressed by the lid when the drawer is in the stowed position and thus in the end position and when the lid is closed, so that ultimately a tension force is exerted on the drawer in the direction of the stowed position. This ensures that the drawer can no longer move in the maintenance position when the lid is closed and is ultimately clamped. This also essentially prevents the drawer from wobbling on its rail, which ensures particularly secure storage of the gas container.
- the gas container has a bent removal tube which is designed to remove a liquid from the gas container.
- the sampling tube thus has a bend, so that the open end of the sampling tube, also called the riser pipe, ends shortly before that wall of the gas container, which is arranged at the bottom in the vertical direction, while the gas container is on the drawer.
- the liquid collects in the gas container so that it can be removed reliably.
- the gas containers which are commercially available are typically equipped with a round or cylindrical outer surface. For example, they are conventional gas bottles.
- the container stowing device has an anti-rotation device which holds the gas container in a predetermined position on the drawer by means of a positive connection with it and a twisting of the gas container, in particular by whose longitudinal or cylindrical axis prevents or only allows in a comparatively very small angular range.
- This is particularly advantageous if it is provided for the operation of the drive motor to remove gas from the liquid phase within the gas container.
- Such bottles have an ascending pipe bent towards its inner end towards the inner lateral surface for gas extraction.
- the bend of the riser pipe runs essentially downwards in the vertical direction, so that the inner end is as deep as possible in the liquid phase is positioned.
- the rotation lock is therefore also a positioning aid. It can also be used to ensure, for example, that the bent extraction pipe is actually arranged with its open end on the vertically lower wall of the gas container, in particular lying there. For safety reasons, too, it is advantageous to prevent the gas container from twisting during operation.
- the anti-rotation device is designed, for example, as a projection on the drawer, which projects in particular in the direction of the gas container and engages in a recess on the gas container, in particular in a recess formed by a grip ring of the gas container, and in this way rotates the gas container by one Axis, especially its longitudinal and / or cylindrical axis, prevented.
- This can therefore in particular also be about an axis which runs parallel to the direction of the linear displacement of the drawer between the stowed position and the maintenance position.
- the container stowage device comprises a fill level sensor, in particular an ultrasound sensor, for measuring the fill level of the gas container.
- the fill level sensor can determine the fill level of the gas container either continuously or at regular intervals.
- the level can be displayed to the operator via a display device, for example. If the soil compaction roller has an on-board computer, the fill level sensor can also be connected to it for documentation and to display the fill level.
- the level sensor is preferably arranged such that it is in the vicinity of the gas container when the drawer and the gas container are in the stowed position. Particularly easy and this is preferably achieved if the fill level sensor, in particular directly, is arranged on the drawer or is integrated in it.
- the fill level sensor is spring-loaded in particular in the direction of the gas container. The level sensor is thus pressed against the gas container by the spring action.
- the level sensor is arranged on the drawer in such a way that it is located under a gas container mounted on the drawer. The spring preload then pushes the level sensor up against the gas tank. In this way, an operator only has to place the gas container on the drawer as normal, without having to deal with the level sensor. The necessary contact or short distance between the level sensor and the gas container is automatically established by the spring action.
- the container stowing device can be arranged anywhere on the soil compacting roller where there is sufficient space. It is particularly preferred that the container stowing device is arranged in the machine longitudinal direction between the front and the rear driving device. For example, the container stowage device is thus arranged in an articulated machine frame on the front car behind the front driving device or on the rear car in front of the rear driving device. In particular, the container stowing device is arranged in the vertical direction in the area of the driving devices. For example, the container stowing device is designed such that the gas container is arranged in the stowed position at the level of the driving devices. In this way, the gas container is covered forwards or backwards by the respective driving device and is protected against unauthorized access.
- the container stowing device is arranged below, in particular directly below, the drive motor.
- the container stowing device is thus designed in such a way that the gas container in the stowed position lies vertically below the drive motor. In this way, the gas container in the stowed position is covered by the drive motor.
- particularly short fuel lines between the drive motor and the gas container are then sufficient.
- “directly below” means that no further parts are arranged between the drive motor and the container stowage device, in particular the gas container itself, except for example a heat protection plate described in more detail below.
- a heat shield is arranged between the bottom and the gas container.
- the heat shield is, for example, a pure shielding part or even provided with a heat insulating / insulating material in order to further reduce the heat transport.
- Such a heat shield can also be arranged between the bottom and the gas container, for example also between the bottom and the drawer.
- the soil is also a considerable source of heat, which can heat up the gas tank. This effect can be reduced or prevented by providing the heat shields.
- the container stowing device has a temperature sensor, in particular for monitoring the interior temperature of the drawer located in the dust position or the corresponding storage compartment in which the drawer is arranged.
- a temperature sensor in particular for monitoring the interior temperature of the drawer located in the dust position or the corresponding storage compartment in which the drawer is arranged.
- the temperature sensor is preferably also connected to a display device via which the measured temperature can be displayed to an operator.
- the temperature sensor can also be connected to an on-board computer which takes over the control of the temperature sensor and / or documents and / or displays the measured values.
- the container stowage device has a cooling device, in particular actively with at least one fan, for cooling the gas container.
- a cooling device can be arranged, for example, under the drawer.
- the cooling device comprises at least one fan, which provides a cooling air flow, by convection heat is removed from the gas container. Even in situations in which heating of the gas container cannot be avoided, for example by the drive motor or by hot asphalt spread on the ground, this can counteract excessive heating of the gas container.
- a safety device which ensures that a driving operation of the soil compacting roller is only possible when the drawer is in the stowed position, in order to prevent a driving operation taking place when the drawer is in the extended state protrudes from the side of the machine.
- a suitable sensor for example a contact sensor
- the contact sensor can be positioned in such a way that it is actuated by the drawer in the stowed position or the closed cover.
- the safety device can further comprise a control unit which, for example, only allows the drive motor to be started, for example by intervention in the motor control, when the sensor detects the drawer in the stowed position.

- the drive energy required for the ferry operation is provided by a gas-powered drive motor 4. According to the definition, the soil compaction roller 1 travels in the operating mode in or against a forward direction a over the soil 8 and compresses it.
- the soil compacting roller 1 can just as well compact backwards, that is, counter to the forward direction a. To protect the operator in the event of a rollover of the soil compaction roller 1, the latter also has a ROPS bracket 6 in a manner known per se.
- the soil compaction roller 1 also has a container stowage device 9 which is designed to receive a gas container which contains the fuel for the gas-powered drive motor 4.
- the container stowing device 9 in FIG. 1 is shown closed by a cover 7. In principle, however, in deviation from FIG. 1, it is also possible to arrange the container stowing device 9 on the rear carriage.

On This ensures that the drawer does not slip away for an operator, for example when changing the gas container.
- the locking device 24 can be released by the operator simply by pulling the spring-loaded bolt against the spring loading.
- a strap 11 is provided on the drawer 12, which can be tensioned via the gas container 10, so that the gas container 10 is fastened on the drawer 12.
- a rotation lock 16 is also arranged on the drawer 12, which positively engages in a corresponding opening in the gas container 10, which in the present case is part of the upper one (or left in the figures) ")
- the grip ring of the gas container 10, in the present case a gas bottle engages and prevents the gas container 10 from rotating about its longitudinal or cylinder axis.
- the anti-rotation device 16 ensures that the gas container 10 is in a desired position on the drawer 12
- the anti-rotation device 16 can also be designed in such a way that it likewise prevents the gas container 10 from slipping in the direction of its longitudinal or cylinder axis ..
- the anti-rotation device 16 therefore also acts as a positioning aid when the gas container 10 is stored on the drawer 12 it indicates to the operator how the gas container 10 is correctly opened the drawer 12 is to be arranged and aligned.
- a locking element 15 may be provided in addition or alternatively.
- the locking element 15 is a rounded truncated cone made of an elastic material, for example rubber.
- the locking element 15 is arranged on the drawer 12 in such a way that it projects beyond the drawer 12. More precisely, the locking element 15 projects beyond the drawer 12 in the direction in which the drawer 12 is moved between the stowed position and the maintenance positions, in particular in the direction of the cover 7.
- the protrusion of the locking element 15 is greater than the distance between the drawer 12 and the cover 7 when the drawer 12 is in the stowed position and the cover 7 is closed (see FIG. 4 for a corresponding illustration).
- FIG. 4 shows a cross section through the soil compacting roller 1 and the container stowing device 9 according to the perspective of Figure 3.
- the drawer 12 and the gas container 10 is in the stowed position.
- the gas container 10 is located vertically under the drive motor 4 and in the forward direction a behind the front driving device 5.
- the gas container 10 is particularly protected by the cover by these components.
- the cover 7 is closed and forms part of the outer surface of the machine. In addition, the cover 7 presses the drawer 12 into the stowed position via the locking element 15 and secures it.
- the gas container 10 comprises a curved extraction tube 18.
- the extraction tube 18 can be connected to a fuel line of the soil compaction roller 1, via which, for example, fuel is conducted to the drive motor 4.
- the sampling tube 18 has a bend, so that the open end of the sampling tube 18 projects vertically downward and can still remove gas from the liquid phase within the gas bottle even when the gas container 10 is almost empty. That the extraction pipe 18 is correctly arranged in the interior of the gas container 10 is also ensured, among other things, by the anti-rotation device 16 already described above.
- the drawer 12 has a fill level sensor 19 which comprises an ultrasonic sensor.
- the fill level sensor 19 is arranged on the drawer 12 in such a way that when the gas container 10 is mounted on the drawer 12, it is located below it.
- the fill level sensor 19 is spring-loaded in the direction of the gas container 10, so that the fill level sensor 19 is pressed against the outer surface of the gas container 10 mounted on the drawer 12. This ensures a reliable level measurement.
- the fill level sensor 19 is either connected to a display device or, for example, to the on-board computer of the soil compaction roller 1. The level of the gas container 10 can thus be displayed to an operator of the soil compaction roller 1.
- the container stowing device 9 comprises a temperature sensor 22. This is located in the space in which the gas container 10 is in the stowed position. The temperature Sensor is also connected to a display device or the on-board computer, so that the operator can be informed about the temperature of the gas container 10, and in particular when one or more threshold temperatures are exceeded.
- heat shields 20 are also provided.
- This heat shield 20 thus prevents the entry of waste heat from the drive motor 4 on the gas container ter 10.
- This heat shield 20 is thus between the bottom 8 and the gas container 10 and thus prevents excessive heat input from hot asphalt to be compressed onto the gas container 10.
- the heat shields 20 can also be provided with a further heat-insulating material and / or be made of a heat-insulating material.
- a cooling device 21 can also be provided.
- the cooling device 21 comprises, for example, one or more fans which cause a flow of cooling air, which in turn convectively dissipates heat from the gas container 10, for example out of the body 23 of the soil compaction roller 1 into the outside environment.
- the cooling device 21 is arranged in the embodiment shown under the drawer 12 and thus also under the gas container 10.
- the invention provides reliable protection against vandalism and theft for the gas container 10.
- the storage of the gas container 10 is simultaneously adapted to its technical requirements.
