Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a safety belt for high-

The present invention relates to a safety belt for high work, more particularly, a safety altimeter and an infrared distance sensor are installed in a safety belt, so that when the safety ring is not fixed at a certain altitude, And more particularly, to a seat belt for a high-altitude work which can prevent a safety accident from being given.

Generally, the safety belt that is worn for the prevention of fall accident at the job site is a safety belt which is worn only at the waist and a swing type safety belt which surrounds the leg / waist / shoulder part. It is a general tendency to use a swing type safety belt that can evenly distribute the load, which causes a large injury such as a vertebral fracture by applying an impact to an operator's waist by a human body load.

Referring to FIG. 1, the conventional swing type safety belt includes a shoulder belt 12 to be worn on both shoulders of a worker, a chest belt 13 to be fastened at the chest of the worker, A backrest belt 14 extending from the both side shoulder belts 12 and crossing over a back portion of the worker and a shoulder belt 14 integrally formed with the shoulder belt 12 and the backrest belt 14, And a belt 16. A support 18 is provided at an intersection of the backrest belt 14 extending from the two side shoulder belts 12 and intersecting with each other. The support rope 20 having the safety collar 17 and the impact absorbing portion 19 is connected to the support 18.

However, since the conventional swing type safety belt has no means for the operator to recognize the safety consciousness, the operator does not use the safety loop 17 of the lifting rope 20 by hanging it on the field structure, It is difficult to prevent a falling accident because the work is generally performed with the shoulder belt 12 hanging.

When the safety collar 17 of the lifesaving rope 20 is used on a site structure, there is no means for informing the other person of the fall when the lifting rope 20 is crashed, resulting in a problem that the rescue operation takes a long time.

In many cases, safety belts of safety belts are not attached to safety belts due to safety frustration and lack of consciousness of many workers in the past. Many fall accidents are caused by non-safety collars. To prevent such problems, worker attitudes such as safety education And the like.

The seat belt 100 according to the present invention is largely composed of a shoulder belt portion 110, a waist belt portion 120, and a leg belt portion 130.

In addition, the safety belt belt 140 is connected to the waist belt unit 110, to which a safety loop 141 to be attached to a field structure (not shown) is connected.

Since the seat belt 100 is widely used, detailed description thereof will be omitted.

The measuring unit 200 is installed in the waist belt portion 120 of the seat belt 100 to measure the distance between the floor and the seat belt 100 worn by the worker.

When the distance between the floor surface and the seat belt 100 is measured, the measurement unit 200 is electrically connected to the control module 300 so that the measured altitude and position can be controlled by the control module 300 .

The measuring unit 200 includes an infrared distance sensor 210 for measuring the distance between the floor and the seat belt 100 and a pressure altimeter 220 for measuring the altitude of the seat belt 100.

The infrared distance sensor 210 measures the distance by monitoring two or more points of infrared rays projected and infrared rays projected.

At this time, the measurement distance of the infrared distance sensor 210 can be measured up to a distance of about 1 cm.

In addition, a plurality of infrared distance sensors 210 are installed to accurately measure the distance between the floor surface and the seat belt 100.

Meanwhile, when the infrared distance sensors 210 are installed in a plurality, the waist belt 120 is installed diagonally.

That is, the position of the wearer can be measured by the infrared ray distance sensor 210 when the seatbelt 100 is worn.

The pressure altimeter 220 measures an altitude of the position of the seat belt 100 with a change in atmospheric pressure according to the altitude.

At this time, the measurement distance of the pressurized altimeter 220 can be measured up to a distance of about 1 m.

In addition, the pressure altimeter 220 is installed remotely from the GPS module 230 so as to correct an accurate position of the seat belt 100.

On the other hand, the altimeter 220 is digitally displayed at an altitude between the seat belt 100 worn by the wearer and the floor surface.

The control module 300 is electrically connected to the measurement unit 200 to receive and control the measurement signal of the measurement unit 200 so that the safety ring 141 of the seat belt 100 is fixed to the structure And can send a signal to the notification unit 500 when it reaches the position of the specific bullying operation.

The control module 300 is electrically connected to a power supply unit 400 having a battery 410.

The notification unit 500 is electrically connected to the control module 300 and receives a signal controlled by the control module 300. When a position corresponding to a specific high-pressure operation is detected, an alarm is sounded.

The notification unit 500 includes a speaker 510 that sounds an alarm sound according to a signal of the control module 300 and an LED 520 that generates a notification alarm by light.

That is, when a position corresponding to a specific high-level work is sensed from the measurement unit 200, the control module 300 receives a signal from the control unit 300 and sends a signal to the notification unit 500 to be output by the speaker 510 and the LED 520 An alert alarm is generated to notify the safety loop 141 to be collated.

A safety loop belt belt 140 to which a safety loop 141 is connected is installed on the seat belt 100 and a magnetic contact sensor 150 connected to the control module 300 is installed on the safety belt belt 140 .

3, when the magnetic contact sensor 150 is brought into contact with the seat belt 100 under the control of the control module 300, the notification alarm continues to be sounded through the notification unit 500, The notification alarm of the notification unit 500 is stopped when the magnetic contact sensor 150 is pulled down by pulling the safety hook 141 for binding the safety ring 141 as shown in FIG.

Example  2.
