Fig. 2 is a perspective view of the main part of Fig. 1,

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes a device for maintaining the horizontal position of the hull (10) with respect to the evacuation passage (20). The hull 10 is intended for a ship or an offshore structure but is not necessarily limited thereto and may include a land structure or the like. The evacuation passage 20 of the hull 10 is provided with a module satisfying the explosion-proof grade such as an independent air conditioner (HVAC), lighting, and insulation.

According to the present invention, the footrest (25) is installed in the evacuation passage (20) so as to be capable of attitude change. The footrest 25 is installed in a structure that mounts or can change the attitude without interfering with equipments such as HVAC, lighting, and insulation. The footrest 25 is kept spaced apart from the inner surface of the evacuation passage 20 for ease of posture variation. The horizontal posture of the foot plate 25 does not always mean a planarization orthogonal to the direction of gravity but includes inclination within a range in which the occupant can safely walk.

According to the detailed configuration of the present invention, the footrest (25) is rotatably supported inside the evacuation passage (20) through a hinge shaft (22). The hinge shaft (22) is selectively installed in the longitudinal direction or the width direction of the evacuation path (20). According to this method, the rotation direction of the foot plate 25 is determined, which is advantageous in terms of simplicity of construction and reliability of operation. However, since the attitude change of the footrest 25 is limited to the uniaxial motion, it is necessary to apply the variable application depending on the installation condition of the evacuation passage 20. [

According to the present invention, the elevating means (30) is provided to provide a driving force for the attitude change of the foot plate (25). The elevating means 30 performs upward and downward movements at one point or a plurality of points of the footrest 25 to ultimately maintain the horizontal posture of the footrest 25 regardless of the inclination of the evacuation passage 20. [

According to the detailed configuration of the present invention, the elevating means 30 includes a rake-shaped gear 31 coupled to the foot plate 25, a pinion gear 32 meshing with the rack gear 31, And a motor 33 connected thereto. In the case of Fig. 2, the rail 31 is provided on the bottom surface of the foot plate 25 on the opposite side of the hinge shaft 22. The pinion gear 32 is installed on the bottom surface of the evacuation passage 20 while being engaged with the rack gear 31. The motor 33 uses a forward and reverse servo drive system, and coaxially connects the pinion gear 32 to its rotation shaft.

Thus, when the motor 33 rotates, the rake surface 31 is raised or lowered to cause the footplate 25 to rotate, thereby switching to a horizontal posture. The pedal plate 25 and the rack gear 31 interpose a pivotal motion and a link (not shown) that mediates linear motion.

On the other hand, if a worm gear is interposed between the motor 33 and the pinion gear 32, the reduction of the driving torque can reduce the power consumption of the posture maintenance by the reverse prevention function.

The footrest 25 is supported in the elevating means 30 via at least two ball joints 35 so as to be able to move at least biaxially. Fig. 3 shows a state in which the elevating means 30 is provided at the corner of the foot plate 25 via respective ball joints 35. Fig. This can realize a motion of more than two axes with respect to the foot plate 25 by excluding the hinge shaft 22 as shown in Fig. Of course, if the length of the footrest 25 becomes longer, deflection may occur, so that a separate ball joint 35 may be additionally provided in the middle.

According to the present invention, the control means (40) is arranged to input the inclination of the foot plate (25) and apply the output set to the elevating means (30). The control means 40 is installed in the evacuation passage 20 and has a separate independent power source (not shown) in preparation for the power failure of the ship 10. This independent power source is installed at a capacity capable of driving the elevating means 30 and the control means 40. [ The inclination of the pedestal 25 is recognized through inclination of the evacuation passage 20 as the ship 10 sinks.

According to the detailed configuration of the present invention, the control means 40 includes an attitude sensor 41 for detecting inclination of the foot plate 25, an encoder 43 for detecting the rotational position of the motor 33, And a controller (45) for driving the elevating means (30) by an established algorithm. Although the attitude sensor 41 can increase accuracy based on gyros and accelerometers, it does not exclude MEMS inertial sensors that are low in weight and volume and low in cost. By using the signal of the encoder 43 provided to the motor 33, it is possible to recognize the ascending / descending state (height) of the raising gear 31. The controller 45 includes a microprocessor, a memory, and a microcomputer circuit including an I / O interface. The controller 45 processes a program mounted on the memory and executes a set control algorithm.

2, the controller 45 receives the signal of the attitude sensor 41 and outputs an output to the motor 33 with reference to the data table of the memory when the inclination of the footstep 25 exceeds the set value The output of the motor 33 is turned off and the position of the motor 33 is stored by the signal of the encoder 43. When the inclination of the footrest 25 reaches the proper range, The signal processing of the controller 45 for the attitude sensor 41, the encoder 43, and the motor 33 is repeatedly performed at a predetermined cycle.

At this time, the orientation of the foot plate 25 of Fig. 2 is determined by the hinge shaft 22, so that the orientation sensor 41 can simply use an inclination sensor (not shown). In this case, the inclination sensor may be attached to the motor 33.

3, the controller 45 refers to a more complicated data table for controlling the four elevating means 30 in the memory. The data table stores the rotational positions of the four motors 33 corresponding to the signals of the orientation sensor 41. [ The controller 45 elevates and lowers the respective rack gears 31 connected to the corners of the footrest 25 to maintain the horizontal posture in the set range. As described above, when the ball joint 35 is added in the middle of the foot plate 25, it can be used as a reference point of motion to improve the responsiveness.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
