Definitions
- the present invention relates to an armored vehicle with an emergency exit hatch.
- the armored vehicle referred to in this invention is equipped with two vehicle floors, for example with a trough construction.
- Such a design is common, for example, to minimize the effects of mines, so that the force introduced into the vehicle first acts on a first vehicle floor.
- This first vehicle floor is arranged on the outside of the vehicle and, during normal operation, runs parallel to the floor outside of the vehicle on which the vehicle is driving.
- the second vehicle floor faces the interior of the vehicle and thus forms the vehicle floor on which the crew of the vehicle acts. Both vehicle floors run parallel to each other and form an intermediate space between the first and the second vehicle floor.
- the currently known emergency exit hatches on armored wheeled or tracked vehicles allow safe exit in an emergency situation, such as an accident or major damage such as a mine detonation.
- the emergency exit is often designed as an opening closed by a hatch in the tub floor of the vehicle.
- the degree of protection of this hatch usually corresponds to that of the tub floor (first vehicle floor) of the vehicle.
- Such an emergency exit hatch is known, for example, from DE 102018 112671 A1.
- This document discloses such a floor hatch in an armored vehicle, which can be used as an emergency exit hatch.
- US 2013/0074686 A1 discloses access to a passenger compartment of a vehicle with a double floor.
- the passenger compartment is accessed through a door opening formed in a chassis frame of the passenger compartment, the access system consisting of at least one door.
- This is articulated with respect to the chassis frame by a first horizontal joint and forms a suitable ramp in its open position.
- the first hinge is connected to a bottom edge of the door and a bottom edge of the door opening.
- the lower edge of the door corresponds to the door in its closed position.
- DE 10 2006 011 611 A describes a vehicle for passenger transport, a standard container being converted into a crew housing.
- the interior of the container is divided into a crew room and an equipment room.
- An emergency exit opening is provided in the ceiling of the container, which can be closed by means of a lid that can be evaluated.
- a folding ladder or rope ladder for exiting the container is arranged at the door.
- the object of the present invention is therefore to design an emergency exit hatch for armored vehicles in such a way that the emergency exit hatch can still be opened even in difficult situations or unusual situations in order to be able to evacuate the crew of the vehicle.
- the invention is also intended to serve to support the opening of the emergency exit hatch if it cannot be opened by the action of gravity even in the normal position as a result of a deformation caused, for example, by an act of violence.
- the invention therefore relates to a stationary lifting device for lifting an emergency exit hatch, which can be used within the chassis of an armored wheeled or tracked vehicle in the lower area near the bottom of the tub.
- the lifting device enables the crew of wheeled and tracked vehicles to open the emergency exit hatch in any position.
- the lifting device can be driven electrically, hydraulically or mechanically.
- a drive which is preferably designed as a hydraulic motor.
- the realization of the lifting movement of the lifting device can be carried out via a lifting cylinder, which is made possible as a hydraulic cylinder, scissor lift table, rack and pinion drive, threaded rod drive or via a linear chain.
- a lifting cylinder which is made possible as a hydraulic cylinder, scissor lift table, rack and pinion drive, threaded rod drive or via a linear chain.
- the lifting cylinder can be arranged in the intermediate space by means of a bearing block.
- the bearing block is preferably designed to be pivotable in order to be able to pivot the lifting cylinder.
- the lifting cylinder can be designed with a locking pin, which creates an articulated connection between the lifting device and the bearing block on the bearing block.
- power can be transmitted to the emergency exit hatch by supporting the lifting device on the bearing block.
- the lifting cylinder When the lifting device is not in use, the lifting cylinder can be pivoted and stored in the intermediate space to save space.
- the lifting device also includes a base plate, via which the lifting movement can be transferred to the emergency exit hatch.
- a linear chain can also be used to implement the lifting movement.
- the linear chain consists of specially formed chain links.
- the chain links interlock with each other and support each other.
- the chain links can work in both directions. A linear chain can thus pull and push.
- the rigid chain is rigid in one direction, here in the direction of the lifting movement.
- the principle of the linear chain enables space-saving stowage in the vehicle, preferably in a linear chain store.
- the linear chain can be deflected by using a pinion, so that the linear chain accumulator can be arranged horizontally in the intermediate space. This enables a space-saving accommodation of the linear chain in the intermediate space.
- a gear wheel, a guide or a combination of a guide and at least one gear wheel can be used as a pinion in the sense of the invention.
- the pinion can be drivable or designed as a passive mechanical component.
- the advantage of the lifting device is the stationary installation and the arrangement in the intermediate space. This arrangement reduces the preparatory measures up to the emergency opening of the emergency exit hatch.
- the pinion or linear chain is preferably driven by a hydraulically operated hydraulic motor.
- other drives are also conceivable, for example electrical or mechanical. If the energy source fails in an emergency, manual operation via a gear with a hand crank is possible in one embodiment.
- the hoist is safely stowed near the emergency exit hatch when not in use.
- the lifting movement is preferably initiated via the pinion and the linear chain on a linear chain connection which is attached to the base plate.
- the rigid chain connection is preferably designed as a spherical bearing.
- the emergency exit hatch has locking means.
- the emergency exit hatch can be locked and the emergency exit hatch can be opened by means of these locking means.
- the base plate preferably contains at least one roller conveyor, particularly preferably two roller conveyors and a rotary table bearing.
- the emergency exit hatch can be lifted out of its opening in the first vehicle floor via the base plate.
- a ball roller conveyor can also be used instead of the roller conveyor.
- the emergency exit hatch rolls as a result of the weight of the emergency exit hatch, which exceeds the sliding friction force of the roller conveyor in conjunction with the degree of freedom of the rotary table bearing from the base plate. This means that the escape route for the vehicle crew is free once the linear chain has been retracted.
- the emergency exit hatch Due to the high mass of the emergency exit hatch and the sliding properties between the roller conveyor and the emergency exit hatch, the emergency exit hatch can roll off the roller conveyor.
- the direction of the rolling movement depends on the position of the vehicle involved in the accident. This circumstance of the degree of freedom restriction, which the roller conveyor cannot reproduce, is solved by the rotary movement of a rotary table bearing.
- a rolling movement of the emergency exit hatch can be ensured when the vehicle is in an exactly horizontal position by arranging the lifting device and the joint bearing on the rigid chain connection off-centre.
- An armored vehicle with an emergency exit hatch and a lifting device for opening the emergency exit hatch is proposed.
- the vehicle has two vehicle floors, so that an intermediate space is created between the two vehicle floors.
- a first vehicle floor is designed as a border between the vehicle and the outside area on the tub side.
- a second vehicle floor is designed for this purpose on the inside of the vehicle.
- the emergency exit hatch is arranged in an opening in at least one of the vehicle floors in the vehicle.
- the vehicle also has a drive and the lifting device is arranged in a stationary manner in the intermediate space of the vehicle. By means of the drive, the lifting device can now act on the emergency exit hatch in such a way that the emergency exit hatch is lifted out of the opening and thus transferred to an open state.
- Fig. 1 Lateral sectional view through the trough floor of an armored vehicle according to the invention with an extended linear chain as a lifting device;
- Fig. 7 Lateral sectional view through the trough floor of an armored vehicle according to the invention with a retracted lifting cylinder as a lifting device in the operational position.
- FIG. 1 shows a section of a vehicle according to the invention with an emergency exit hatch 6 and a drive 2.
- the drive is designed specifically for moving a lifting device, the lifting device being implemented by a linear chain 3 in this figure.
- the vehicle has two vehicle floors 4 , 7 which form an intermediate space 20 .
- the lifting device is arranged in the intermediate space 20 and can act on the emergency exit hatch 6 .
- the two vehicle floors 4, 7 are formed by a first vehicle floor 4, which delimits the vehicle from the outside area 19.
- the first vehicle floor 4 runs parallel to the floor on which the vehicle is driving.
- the second vehicle floor 7 is parallel and spaced apart from the first vehicle floor 4, so that the gap 20 is formed by the two vehicle floors 4,7.
- the second vehicle floor 7 forms the delimitation of the vehicle towards the interior of the vehicle.
- the two vehicle floors 4, 7 have a minimum distance 18, which is required by the overall height of the lifting device and the possible depth of deformation when force is applied to the first vehicle floor 4.
- the rigid chain 3 consists of specially formed chain links.
- the chain links interlock with each other and support each other. Unlike a roller chain, it works in both directions, it can pull and push. This has the advantage that the rigid chain 3 is rigid in one direction, here in the direction of the lifting movement.
- the principle of the linear chain 3 enables space-saving stowage in the vehicle.
- An advantage of the lifting device according to the invention is the stationary installation and the arrangement in the space 20. This arrangement reduces the preparatory measures up to the emergency opening of the emergency exit hatch 6.
- the drive 2 here drives a pinion 13 which can set the linear chain 3 in motion.
- This drive 2 is preferably designed as a hydraulically operated hydraulic motor.
- the linear chain 3 itself can be accommodated in a linear chain store 1 . Due to the deflection of the rigid chain 3 at the pinion 13, the rigid chain 3 can be stored in a space-saving manner in the rigid chain store 1, since this runs parallel to the vehicle floors 4, 7.
- the lifting device is safely stowed in the vicinity of the emergency exit hatch 6 in the intermediate space 20 when not in use.
- the lifting movement is transmitted to the base plate 5 via the pinion 13 and the linear chain 3 .
- the rigid chain 3 is fastened to the base plate 5 via a rigid chain connection. This is preferably designed as a pivot bearing 17 .
- the emergency exit hatch 6 can have at least one locking means.
- the emergency exit hatch 6 can be unlocked by actuating this locking means. In the normal case, the emergency exit hatch 6 then falls to the ground under its own weight and releases an opening in which the emergency exit hatch 6 is kept in the closed state. The opening extends through the first vehicle floor 4.
- FIG. 2 shows a detailed view of the base plate 5 via which the thrust of the rigid chain 3 can be transmitted to the emergency exit hatch 6 .
- the base plate 5 can consist of two roller tracks 8 and a bearing 10 .
- the roller conveyors 8 are arranged on the bearing 10 via an intermediate plate 9 .
- Contact with the emergency exit hatch 6 is established via the roller conveyors. All of the above is arranged on a foundation plate 11 and forms the base plate 5, which can be connected to the rigid chain via a rigid chain connection 12.
- the emergency exit hatch 6 Due to the high mass of the emergency exit hatch 6 and the sliding properties between the roller conveyor 8 and the emergency exit hatch 6, the emergency exit hatch 6 can roll off the roller conveyor. The direction of the rolling movement depends on the position of the vehicle involved in the accident. This circumstance of the restriction in the degree of freedom, which the roller conveyor 8 cannot reproduce, is solved by the rotary movement of the bearing 10 . Due to the eccentric arrangement of the Lifting device and a joint bearing on the rigid chain connection 12, a rolling movement of the emergency exit hatch 6 can be guaranteed when the vehicle is in an exactly horizontal position.
- FIG. 3 shows the retracted linear chain 3, which is accommodated in the linear chain store 1.
- a drive 2 acts on the pinion and this deflects the pushing movement of the rigid chain 3 from the rigid chain accumulator 1 to the emergency exit hatch 6 .
- the push chain 3 can then transfer its thrust to the emergency exit hatch 6 via the base plate 5 .
- the emergency exit hatch 6 is arranged in the first vehicle floor 4 .
- the lifting device is arranged in the space between the first vehicle floor 4 and the second vehicle floor 7 .
- FIG. 4 shows a detailed view of the pinion 13. This forms one end of the linear chain accumulator 1.
- the linear chain 3 can thus move along the linear chain storage device 1 and be deflected via the pinion 13 .
- FIG. 5 corresponds to a lifting device from FIG. 1, but a lifting cylinder 14 is now used for the lifting device.
- a hydraulic cylinder designed as a differential cylinder is preferably selected, but electrical or mechanical lifting cylinders are also conceivable.
- the lifting cylinder 14 is preferably equipped with a safety device, for example a lowering brake holding valve, which prevents the piston rod from being lowered quickly, for example due to a rapid loss of pressure.
- a safety device for example a lowering brake holding valve
- the hydraulic cylinder can be operated via the vehicle's hydraulic system.
- the vehicle pan consists of two vehicle floors 4, 7, which form an intermediate space.
- a base plate 5 is used in the lifting cylinder 14 , via which the lifting device can act on the emergency exit hatch 6 .
- the lifting cylinder 14 can be articulated via a bearing block 15 on one side in the intermediate space. On the side of the lifting cylinder 14 opposite the bearing block, it can be fastened to the base plate via a joint bearing 17 .
- FIG. 6 shows that the lifting cylinder can be swiveled to the side and can thus be brought from an operating position into a swiveled position.
- the lifting cylinder 14 is tilted to the left and can be locked there.
- locking means are proposed, which are not shown. This allows space-saving stowage in the vehicle.
- the hydraulic cylinder is folded into the upright position (operational position) and secured with the aid of a locking pin 16, preferably a ball locking pin.
- Figure 7 shows the retracted lifting cylinder 14, which is in the position of use.
- a drive 2 acts on the lifting cylinder 14 and can extend it.
- the lifting movement of the lifting cylinder 3 is thus transmitted to the base plate 5 .
- the lifting cylinder 14 can then transfer its thrust to the emergency exit hatch 6 via this.
- the emergency exit hatch 6 is arranged in the first vehicle floor 4 .
- the lifting device is arranged in the space between the first vehicle floor 4 and the second vehicle floor 7 via a bearing block 15 .
- the device is securely stowed in the pivoted position of the lift cylinder near the emergency exit hatch 6 when not in use.
- the lifting movement is preferably introduced via the hydraulic energy, consisting of volume flow and pressure on the piston rod of the hydraulic cylinder.
- the base plate 5 is mounted on the piston rod, via which the power transmission to the emergency exit hatch 6 is initiated.
- a lock of the emergency exit hatch 6 can be unlocked, similar to the design as a linear chain.
- the emergency exit hatch 6 Due to the high mass of the emergency exit hatch 6 and the sliding properties between the roller conveyor 8 and the emergency exit hatch 6, the emergency exit hatch 6 can roll off the roller conveyor 8.
- the direction of the rolling movement depends on the position of the vehicle involved in the accident. This circumstance of the restriction in the degree of freedom, which the roller conveyor 8 cannot reproduce, is solved by the rotary movement of a bearing 10 . Due to the eccentric arrangement of the lifting device and the joint bearing 17 as a connection, a rolling movement of the emergency exit hatch 6 can be guaranteed when the vehicle is in an exactly horizontal position.
- the present invention is not limited to the aforesaid features. Rather, other versions are conceivable.
- the lifting cylinder can be designed as an electric or pneumatic lifting cylinder. Rods and levers can also be provided, which can eliminate the movement of a jammed emergency exit hatch as a result of deformation.
