Description

Wireless remote controller for ascender

The present invention relates to a wireless remote control for a lift device, and more particularly, to a wireless remote control for a lift device that operates according to a user's movement.

In Korea, various types of high-rise fires have been occurring continuously since the past, but with current domestic firefighting equipment or firefighting technology, it is difficult to quickly extinguish a fire when a fire occurs in a building with more than 15 floors. A number of devices have been proposed for escape and rescue, and a typical escape equipment is a bunkanggi.

The stiffener allows the victim to quickly escape to a safe place from the fire site in the event of a fire in a high-rise building such as a building or apartment. Various types of configurations have been proposed as a device that supports the escape of a fire phenomenon to a safe place while descending.

For example, in Public Utility Model No. 1998-026059, a loop; a pulley for winding up the loop; a reduction unit for reducing the rotation speed of the pulley; a coupling plate for coupling the loop, pulley, and reduction unit; And the configuration of the wanganggi consisting of a cover plate and the like coupled to the upper direction of the coupling plate is disclosed.

In addition, in Patent Registration No. 1311643, the V-type brake first gives a deceleration effect, so that even when a solid weight is suspended, the reduction wheel feels the same load as a low weight person hanging, so even an overweight person can be stubborn at a low speed like an underweight person. , In addition, since the V-type brake bears a part of the body weight of the evacuator, the fatigue of other stiffener parts is reduced, and a configuration is disclosed that can use the armband for a long time.

However, in the case of the reinforcing machine, it is installed only in buildings with less than 10 floors, and the frequency of use is extremely low due to ignorance or negligence in management in case of a fire.

At this time, the rescue method by firefighters or firefighting equipment is largely divided into a method using an elevated ladder truck and a rope method by a firefighter. It takes time and it is often difficult to respond to urgent rescue issues.

In addition, the method using a rope or a reel is mainly used for the rescue method by means of a rope, and since it is necessary to descend and stop using the hands, considerable strength and risk exist.

However, the method using the rope or reel has the advantage of convenient transport and use of equipment, and is being used more and more in other rescue sites.

For example, a tripod reel is used at the site of a manhole fall accident, and in this case, several people have to support the tripod reel. Significant strength is required and it is difficult to tow at least 2-3 people to lift the injured person.

As an improvement of the conventional methods as described above, a rope-type elevating device using a separate power source may be used. As disclosed in Korean Patent Registration No. 2127091, the lifting device includes an engine or a motor; a rotating shaft rotated by power generated from the engine or motor; a rope drum which is rotated according to the rotation of the rotating shaft, and on which a rope is wound; a power transmission housing accommodating the rotation shaft inside; a space portion formed on an inner surface of the power transmission housing; and a support roller accommodated in the space and selectively caught on the outer surface of the rotation shaft according to movement.

That is, it is a configuration that ascends or descends along a rope installed using an engine or a motor, and can be used for firefighting according to quick and convenient use, and has the advantage of being able to be used for military purposes such as penetration of buildings and penetration of ships.

In the power-type lifting device as described above, a manipulation unit is installed in the main body for the operation of the driving source, and the user operates the manipulation unit attached to the main body to perform an operation such as rising, lowering, or stopping. Since most of them are moved with firefighting equipment or military equipment, it is difficult to operate them by hand.

First, the wireless remote controller 100 for a lifting device according to the present invention is characterized in that it is applied to the lifting device 10 as shown in FIG. 1 .

The lifting device 10 includes a body 11 having a driving source 12 disposed therein, and a v-shaped pulley that rotates by the driving source 12 on the front of the body 11 and winds the rope 1 . A rope drum including a 13, a guide 14 for guiding the rope 1 to the rope drum 13, and preventing the rope 1 from being separated from the rope drum 13, and the operation of the power source and a manipulation unit 15 for controlling the rotation direction, rotation speed, and operation of the rope drum 13 by adjusting the .

Here, the driving source 12 may be implemented as a motor driven by electricity or an engine driven through a separate fuel.

Also, a speed change device for changing the rotational speed may be disposed between the driving source 12 and the rope drum 13 .

Of course, if necessary, the lifting device 10 includes a clutch that determines whether or not the drive source 12 and the rope drum 13 are mechanically connected, and the rope 1 and a brake that acts as a braking force to prevent sudden descent. can

Here, the rope 1 is configured to have one end or both ends tied in advance to an area for ascending or descending, and the lifting device 10 winds up the rope 1 to ascend or descend.

The user relies on a support string extending from the body 11 of the lifting device 10 and moves together when the lifting device 10 rises. Of course, in the case of descending, the descending speed can be controlled by an appropriate brake action.

The manipulation unit 15 is a part operated by the user, and the signal of the manipulation unit 15 is transmitted to the control unit 20 installed therein, and the control unit 20 controls the operation of the driving source 12 .

That is, the control unit 20 controls the rotation direction and the rotation speed of the driving source 12 according to the signal of the manipulation unit 15 .

Accordingly, the user may operate the operation of the lifting device 10 through the manipulation unit 15 .

Although the elevating device 10 has been described as a configuration that moves by the rope 1, the wireless remote control 100 for the elevating device according to the present invention is a rope type as well as a rope type as well as an object or a person to move in the vertical direction. It is also applicable for the control of the lifting device 10 that moves objects or people by the operation of a driving source, such as a lift, a hoist and a winch for transporting objects.

Accordingly, the lifting device 10 of the present invention is meant to include industrial devices such as a hoist, a winch and a lift, as well as a rope-type lifting device.

The wireless remote controller 100 for a lifting device according to the present invention is applied to the lifting device 10 as described above, and as shown in FIG. 2 , a transmitter 40 and a receiver for receiving signals from the transmitter 50 ( 80) is included.

As shown in FIG. 3, the transmitting unit 40 includes a switch unit 60 including a separate battery and a plurality of switches for user manipulation, a transmitting radio module 52 for outputting a radio signal, and a transmitting unit. The acceleration sensor 53 that outputs a signal according to the movement of 40, processes the state of the switching unit 60 and the output value of the acceleration sensor 53, and also sends a control signal to the transmission wireless module 52 and a transmission processing unit 51 to output.

The transmission wireless module 52 serves to wirelessly transmit the signal output from the transmission processing unit 51, and is preferably implemented using a short-range wireless communication protocol such as Bluetooth or Zigbee.

In addition, the transmission processing unit 51 transmits a corresponding control signal through the transmission wireless module 52 when the setting or setting is changed in the switch unit 60 .

4 , the switch unit 60 includes a power unit 61 , a rotation unit 62 , a speed unit 63 , an operation unit 64 , and a mode unit 65 .

Here, the power supply unit 61 serves to turn on/off the transmitter 40, and when it is set to on, the transmitter 40 operates, and when it is set to off, the transmitter 40 ends as an operation. do. Of course, when the power supply unit 61 is set to be off, the lifting device 10 operates only by the operation unit 15 .

The rotating part 62 is configured to adjust the rotation direction of the rope drum 13 . That is, the rotation direction of the rope drum 13 can be set to a clockwise or counterclockwise direction by selecting the rotating part 62 .

The speed unit 63 is a switch capable of adjusting the rotational speed of the rope drum 13 , and the user can adjust the rising/falling speed through the speed unit 63 .

The operation unit 64 performs a function of selecting on/off of the rotation of the rope drum 13, and a switch indicating whether the rope drum 13 operates according to the speed and rotation direction set in advance by the user. to be. For safety, the rope drum 13 rotates only when the operation unit 64 is pressed, and the rotation is stopped in the rest of the state.

The mode unit 65 is a switch serving to select a normal mode for outputting a control signal through the operation of the switch units 60 and a vibration mode for outputting a control signal according to the self-acceleration of the transmitter 40 .

When the mode unit 65 is set to the normal mode, all the operations are performed by the switch unit 60 attached to the transmitter 40 .

On the other hand, when the mode unit 65 is set to the vibration mode, whether the operation unit 64 is operated is set based on the value output from the acceleration sensor 53 .

That is, when the mode unit 65 is set to the vibration mode, the transmission processing unit 51 inverts the state of the operation unit 64 when the transmission unit 40 moves at a constant acceleration or more, and again with a constant acceleration As described above, when the transmitter 40 moves, the control is performed in such a way that the state of the operation unit 64 is inverted.

Therefore, if the transmitter 40 is worn on the user's upper arm, the speed and the rotation direction are set, and then set to the vibration mode, the upper arm is vibrated to repeatedly adjust whether the rope drum 13 rotates.

When vibrating once, the rope drum 13 rotates, when vibrating once more, the rope drum 13 stops, and when vibrating again, the rope drum 13 may be configured to perform a rotation control.

If necessary, the transmission processing unit 51 outputs a rotation signal of the rope drum 13 when two or more vibrations are continuously performed, and when only the lower vibration is input, the rope drum 13 is stopped. can be controlled

The acceleration sensor 53 may be selectively implemented among 1 axis, 2 axes, or 3 axes, and in the case of 1 axis and 2 axes, it is preferable to configure the acceleration sensor 53 to match the angle best indicated by the motion characteristics of the upper arm, 3 In the case of a shaft, it is preferable because it can be installed without considering the direction.

When the output by the three-axis acceleration sensor 53 is x, y, and z, the acceleration value a is composed of the following equation.

a=(x ² +y ² +z ² ) ^1/2

That is, the value a is a positive value indicating the absolute magnitude of a vector having the acceleration value of each axis as a unit component.

Of course, in the case of the two-axis acceleration sensor 53, only x and y outputs are calculated, and in the case of the single-axis acceleration sensor 53, the acceleration value is calculated as an absolute value of a single output.

When the value a is equal to or greater than a certain level, the transmission processing unit 51 determines that the user has a will to change the operation and outputs a corresponding control signal.

Meanwhile, when the power is turned on, the transmission processing unit 51 may be configured to transmit a basic signal without a separate operation.

Accordingly, even if there is no special control signal, a basic signal is output, and when the receiving unit 80 receives the basic signal, it can be recognized that the transmitting unit 40 is operating correctly.

On the other hand, as shown in FIG. 5, the outer shape of the transmitter 40 includes a separate casing 41 and a fixing part 42 for fixing the casing 41, and on the surface of the casing 41 The switch part 60 for operation is formed.

Here, the fixing part 42 may be configured in the form of a belt having appropriate elasticity, and if necessary, may also be implemented in a form for fixing by attaching a hook-and-loop fastener to the belt.

Meanwhile, the receiving unit 80 may be implemented inside the control unit 20 , but functionally, it will be described separately from the control unit 20 .

As shown in FIG. 6 , the reception unit 80 includes a reception processing unit 81 and a reception wireless module 82 connected to the reception processing unit 81 .

In addition, the receiver 80 receives the control signal transmitted from the transmitter 40 , recognizes the received control signal, and controls the driving source 12 by an operation corresponding to the signal.

In addition, the reception processing unit 81 continuously receives the basic control signal transmitted through the transmission unit 40, and if there is no abnormality in the basic control signal, it is determined that the connection of the transmission unit 40 is good, and then the control signal is transmitted When it is received, it performs the control implementing the corresponding operation.

Of course, in the case of the engine-type driving source 12, it may be implemented in the form of controlling the operation of the transmission in order to change the direction.

If the basic control signal is not received, the reception processing unit 81 determines that the connection with the transmission unit 40 is irregular and stops the wireless operation.

On the other hand, in the wireless remote controller 100 for a lifting device according to the present invention, when the mode unit 65 is set to vibration and the transmitter 40 is mounted on the user's upper arm as shown in FIG. Move the arm so that the lifting device 10 is driven, and when stopping the operation during ascending or descending, the upper arm may be moved more than a predefined acceleration.

That is, even if both arms are in possession of an object or a rifle, it is possible to control whether the lifting device 10 is operated only by the operation of the upper arm.

If necessary, it is obvious that the control may be implemented in a form in which control is performed on various types of acceleration values.

If necessary, the remote control 100 may be vibrated by hand to control whether the driving source 12 operates or not.

What has been described above is only an embodiment for implementing the wireless remote control for a rope-type lifting device according to the present invention, and the present invention is not limited to the above-described embodiment, and there is no deviation from the gist of the present invention claimed in the claims below.
