Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the platform safety scaffolding drive device according to the present invention.

The accompanying drawings are provided to help the understanding of the present invention, and for convenience of description, some of the configurations are shown to be somewhat exaggerated and ignored.

The support rotation shaft 170 supports the safety scaffolding from the bottom and rotates the safety scaffold by rotation, and the roll 160 is rotatably coupled to one end bent and bent in a '-' shape, and the other end is a hinge bearing ( 176).

Since the support rotating shaft 170 is a rotating member, it is fixed to the front surface of the boarding point by the clamp 172 via the bearing 174 at an intermediate position in the height direction.

At a position adjacent to the other end of the support rotation shaft 170, the support rotation shaft 170 is inserted between the tongs 152 formed at one end of the rotation lever 150, and fixed by, for example, a bolt, and supported by the rotation of the rotation lever 150. Rotation axis 170 rotates within a predetermined angle range, such as 90 degrees.

The other end of the rotation lever 150 is coupled to the link bar 140, and the cam lever 142 and the rotation lever 150 by the cam floor 142 so that the rotation lever 150 can rotate in accordance with the linear movement of the link bar 140. Link bar 140 is coupled.

In addition, the link bar 140 and the connecting rod 120 are coupled through an electromagnetic lock 130.

Electromagnetic lock 130 is a body 131 coupled to the link bar 140 by a bolt 133, and an amateur couples to one end of the connecting rod 120 and selectively coupled to the body 131 by magnetic force. 132.

As is well known, when power is applied to the main body 131, the amateur 132 is coupled to the main body 131 by being attached to the main body 131 by electromagnetic, and when the power is cut off, electromagnetic is not generated, so the amateur 132 is the main body ( 131).

In addition, the other end of the connecting rod 120 is connected to the cylinder shaft 110 of the cylinder 100. In this case, the cylinder shaft 110 and the connecting rod 120 are coupled via a rod end bearing 112 so that the cylinder shaft 110 can perform a rotary movement while performing a linear movement.

On the other hand, the end of the link bar 140 in the direction in which the cylinder shaft 110 is returned (indicated by the arrow) is fixed to the structure (not shown) via the spring 144 so that the link bar 140 is always the spring 144. Force in the direction in which the cylinder shaft 110 is returned by the restoring force of).

Although not shown in the drawings, operations such as driving the cylinder 100 and supplying power to the electromagnetic locking device 130 may be performed by a controller, and may be provided in the form of a control box containing a circuit board on which a microprocessor is mounted. Can be.

According to this structure, when the cylinder shaft 110 is linearly moved in the direction indicated by the arrow by the driving of the cylinder 100, the connecting rod 120 coupled to the cylinder shaft 110 by the rod end bearing 112 is the cylinder Linear movement along axis 110.

As described above, when power is applied to the main body 131 of the electromagnetic locking device 130, the armature 132 coupled to the connecting rod 120 is attracted to the main body 131 is attached and coupled to the connecting rod 120 The linear motion of is transmitted to the link bar 140.

As described above, the link bar 140 is connected to a plurality of rotation levers 150 so that the link bar 140 is moved in a straight line in the diagonal direction, at the connection point of the rotation lever 150 and the link bar 140 The cam floor 142 causes the rotation lever 150 to rotate as indicated by the arrow.

As a result, the support rotation shaft 170 fixed to one end of the rotation lever 150 rotates clockwise when viewed from above.

In summary, the linear motion of the cylinder 100 is finally converted into the rotational motion of the support rotational shaft 170 and transmitted.

The front of the landing 200 is installed with a fixing bracket 210 for fixing the safety footrest in the longitudinal direction.

As shown, the fixing bracket 210 is, for example, bent into a 'b' shape so that the vertical portion is fixed by, for example, bolts on the front of the landing 200, and the safety foot through the hinge 212 at the end of the horizontal portion ( 220 combines.

Therefore, the safety scaffold 220 is deployed at the center of the hinge 212 and parallel to the upper surface of the platform 200 to be disposed in the interval between the electric car and the platform 200, or folded to be arranged side by side with the front of the platform 200. do.

As described above, the lower surface of the safety scaffold 220 is supported by the roll 160 of the support rotation shaft 170 and at the same time the rotational movement of the support rotation shaft 170 via the roll 160 is the safety scaffold 220 ) Is converted into a rotational motion, which will be described later.

An accommodating structure 230 for accommodating the safety scaffold driving device of FIG. 1 is installed on the lower surface of the landing 200.

The storage structure 230 shown in FIG. 2 is merely an example, and the storage structure having other various structures may be presented.

The accommodating structure 230 includes an accommodating part accommodating the channel part 234 supporting the support rotation shaft 170, the link bar 140, and the cylinder 100.

232 and a slot 236 formed therebetween, through which the rotation lever 150 passes.

The front face of the channel portion 234 may be installed vertically to the shielding portion 235 so that the driving device can be seen from the outside.

Figure 3 shows the folded and unfolded platform safety platform, respectively, Figure 4 illustrates the driving mechanism of the platform safety platform driving apparatus of the present invention.

As described above, the rotational movement of the support rotary shaft 170 is converted into the rotational movement of the safety footrest 220.

Referring to FIG. 4 (b), the guide member 222 having the guide groove 224 formed along the trajectory of the roll 160 moves is installed on the bottom surface of the safety scaffold 200. . For example, an insertion groove may be formed on the lower surface of the safety scaffold 200, and the guide member 222 may be detachably installed inside the insertion groove.

The lower surface of the guide member 222 in contact with the roll 160 of the support rotation shaft 170 may form an uphill slope from the inlet at which the guide groove 224 starts to the exit direction. As shown in a), when the roll 160 of the support rotating shaft 170 first pushes the safety scaffold 220 by contact, the safety scaffold 220 rotates without difficulty by moving the roll 160 smoothly while inclined. can do.

Without installing a separate guide member 222, the lower surface of the safety scaffold 200 may be in direct contact with the roll 160, but the safety scaffold 200 and the roll 160 are all made of steel contact portion This may be badly worn, the rotation of the roll 160 is not smooth due to friction, as a result the rotational movement of the safety scaffold 220 may not be smooth.

Therefore, the above-described problems can be solved by making the guide member 222 made of a material such as Teflon resistant to wear and making it contact the roll 160 by mounting it on the lower surface of the safety scaffold 220.

3 (a) and 4 (a), when the roll 160 of the support rotation shaft 170 is located in the A state, in this state, the safety scaffold 220 is folded and positioned in parallel with the front surface of the landing 200. do.

In this state, when the cylinder shaft 110 comes out of the cylinder 100 and the link bar 140 connected to the connecting rod 120 moves linearly, and the rotation lever 150 rotates, FIGS. 4 (a) and (c) and FIG. Similarly, the roll 160 of the support rotation shaft 170 moves while rotating along the guide groove 224 in the A-> B-> C state.

As a result, the safety scaffold 220 is rotated about the hinge 212 while being pushed by the rotational force of the support rotation shaft 170 and spread out horizontally as shown in FIG. 3 (b) to be disposed in parallel with the upper surface of the landing 200. do.

As described above, according to the platform safety scaffold driving apparatus according to the present invention, the drive mechanism is simple, the structure is simple, and expensive components are not applied, so the installation cost is low.

In addition, it can be easily adjusted to suit various installation environments. For example, if there is a difference in the height of the electric car and the platform can be solved by adjusting the height of the safety footrest 200. According to the present invention, the height of the safety scaffold 200 can be adjusted by adjusting the diameter of the roll 160 or by adjusting the inclination angle or thickness of the guide member 222.

When the electric vehicle runs without the safety footrest folded for various reasons, the safety footrest may be damaged by the collision with the electric vehicle. In this case, in addition to the economic loss caused by the breakage of the safety scaffold itself, the safety scaffold may fall off due to an impact and may injure a passenger in the platform through the screen door.

The safety scaffold applied to the present invention separates the safety scaffold into a main scaffold and an auxiliary scaffold to solve this problem, and the auxiliary scaffold can easily withstand the load in the vertical direction while easily deviating from the impact in the horizontal direction. do.

Referring to FIG. 5, the main footrest 220a corresponding to the electric vehicle door is also divided into a plurality, and the auxiliary footrest 220b is coupled to the front end of each main footrest 220a via the reinforcing plate 240.

The reinforcing plate 240 is fitted to the boundary between the main footing plate 220a and the auxiliary footing plate 220b. The reinforcing plate 240 includes a vertical portion 243 and a horizontal portion 241 so that the cross section forms a T shape.

Cutting grooves 242 are formed at both edges of the horizontal portion 241, for example, until the bottom of the cutting groove 242 is in contact with the vertical portion 243.

A plurality of reinforcement plates 240 are installed in one main scaffold 220a, and are inserted into the main scaffold 220a and the auxiliary scaffold 220b to be fitted to the vertical portion 243 of the reinforcement plate 240 as shown. A hole 221 is formed, and the horizontal portion 241 is fixed to the main and

auxiliary scaffoldings

220a and 220b by bolts 244 while the vertical portion 243 is fitted into the insertion hole 221.

According to this structure, since the shear stress of the vertical part 243 is large with respect to a load from a vertical direction, it can bear enough.

On the other hand, when there is an impact from the horizontal direction, for example, by an electric vehicle, a cutout groove 242 is formed in the horizontal portion 241 of the reinforcement plate 240, so that only the vertical portion 243 is present. It is easily broken, and as a result, only the auxiliary scaffold 220b is separated from the main scaffold 220a.

Although a shock is not often generated by an actual electric vehicle, a collision with the safety scaffold may be expected when the electric vehicle shakes beyond the allowable tolerance, so that the area where the electric vehicle collides becomes a portion adjacent to the edge of the safety scaffold.

Therefore, by reducing the size of the auxiliary scaffold 220b so that only the portion collided by the electric vehicle is separated, it is possible to minimize the damage to the human life due to the separated safety scaffold, and only replace the damaged auxiliary scaffold 220b It has the advantage of low management cost.

In addition, referring to Figure 5, the boundary surface of the adjacent auxiliary footrest 220b is configured to be inclined and opposed to each other. In this way, when there is an external impact in the horizontal direction such as a collision with the electric vehicle, the adjacent auxiliary footrests 220b collide with each other, one slides along the inclination and the other slides in the b direction to collide with each other. Can be somewhat alleviated by dispersion.

In the above embodiment has been described a case where the platform safety platform is normally driven. However, even in a situation such as a power failure or a cylinder failure, the platform safety scaffolding of the present invention can be safely taken.

In the case of a power failure, since the power is not applied to the main body 131 of the electromagnetic lock 130, the amateur 132 is separated from the main body 131. In this case, the spring 144 installed at the end of the link bar 140 is removed. By the restoring force, the link bar 140 moves in the direction of the arrow in FIG. 1 to return to the initial position. As a result, the support rotation shaft 170 is rotated in the same order as described above, so that the roll 160 of the support rotation shaft 170 is in the A state as shown in FIGS. ) Is folded and positioned side by side with the front of the landing 200.

At this time, the restoring force of the spring 144 does not need to be large. As described above, an inclined uphill is formed in the exit direction from the inlet at which the guide groove 224 starts at the lower surface of the guide member 222, so that the spring 144 When the roll 160 moves a predetermined distance by the restoring force, the roll 160 is easily moved along the slope.

On the other hand, when the power failure is released and the cylinder shaft 110 of the cylinder 100 returns to the initial state, the armature 132 coupled to the connecting rod 120 returns to the initial position by the spring 144. The main body 131 of the electromagnetic lock 130 is opposed. At this time, when the proximity sensor (not shown) installed in the main body 131 detects the amateur 132 and sends a detection signal, the controller applies power to the main body 131 to cause the amateur 132 to stick.

In addition, when the cylinder is broken, the safety footrest 220 can be folded in the same manner as above by cutting off the power applied to the electromagnetic locking device 130 using the emergency power cutoff switch.

In addition, the electric vehicle may proceed in a state in which the safety footrest 220 is unfolded due to various other unexpected reasons, and the safety footrest 220 is installed by the electric vehicle by installing an impact sensor on the safety footrest 220 in the direction of progress of the electric vehicle. When the shock is received, the control unit may cut off the power of the electromagnetic locking device 130 based on the generated shock detection signal to take an emergency action.

In the above description, the embodiment of the present invention has been described, but various changes can be made at the level of those skilled in the art. Therefore, the scope of the present invention should not be construed as being limited to the above embodiment, but should be interpreted by the claims described below.
