Abstract
Description
[Technical field]
[0001] This device is a safety device that can be used to prevent accidents during construction machinery operation, and is a pole with an alarm designed to prevent serious accidents caused by rear-ending obstacles and structures in blind spots that cannot be seen by the operator of the construction machinery. [Background technology]
[0002] Conventional safety devices include push-button stop switches, dedicated cameras for checking the rear, safety poles attached to construction machinery, and barricades at fixed positions on construction machinery. However, among the safety devices currently known, there does not appear to be any that are designed to detect danger, automatically stop the device, and prevent accidents. Summary of the Invention
[0003] This invention is a pole with an alarm that was devised to solve the problems described above. When an external force comes into contact with the pole with an alarm and causes it to bend, the switch on the pole with an alarm is activated, and the construction machinery is brought to a safe stop via a safety device attached to the machinery.
[0004] The above-mentioned alarm pole of the present invention is a pole with an alarm that is attached to a construction machine and, when the safety device cannot be accessed, can alert those in the vicinity with an alarm sound and an alarm light via a power source installed on the alarm pole and outside.
[0005] The alarm pole of this invention uses a spring made of metal, with a cushioning material attached to the upper part of the spring and a switch coming out of a power box that passes through the inside of the spring at the lower part, and is characterized by the fact that it is activated when current flows through the alarm pole via an external power source. Effect of the Invention
[0006] The pole with an alarm of this invention is assembled in the manner shown in [Fig. 1] and is composed of a limit protruding from a power box, a switch and a pole processed into a spring shape. The pole with an alarm is characterized by the fact that the switch is turned on and off when the spring pole is bent by an external force.
[0007] The alarm pole of this invention is attached to a place that cannot be seen from the construction machinery, and by contacting the alarm pole with an obstacle, it can activate an alarm sound and alarm light to notify those around, even when the construction machinery cannot automatically stop.It is an alarm pole that can stop construction machinery without contacting the structure above, even during indoor crane work. The following drawings will explain the implementation of this invention.
[0008] Fig. 1 is a perspective view of an embodiment of the alarm pole of the present invention.
[0009] When the cushioning material ▲A▼ of the pole with alarm in Figure 1 comes into contact with a structure, the spring ▲B▼ is bent, which in turn bends the power switch lever ▲C▼ extending from the power box installed at ▲F▼, switching the power source and allowing electricity to flow through the electric wires extending from ▲H▼▲K▼, activating the alarm device.
[0010] The alarm pole of this invention can be attached to the rear part of construction machinery, or to the boom or other parts where there is a possibility of contact with structures, enabling safe work to be carried out. [Brief description of the drawings]

Claims
1. The pole with an alarm is a pole that has been processed into a spring shape, with a cushioning material installed in the upper part of the pole and a switch that comes out of a power box that passes through the inside of the spring installed in the lower part of the spring, and the pole and switch can be operated by flipping the switch.
2. The above-described pole with an alarm is capable of contacting a structure and being bent to activate a switch installed in the power supply box, thereby stopping the operation of the construction machinery in conjunction with a safety stop switch installed on the construction machinery, and is characterized in that the pole with an alarm is attached to the construction machinery.
3. When it is considered impossible to carry out the operation method of claim 2 with the above-mentioned method of using the alarm pole, it is also possible to use the alarm pole by directly supplying external power to the alarm pole and converting it so that electricity can be transmitted to the alarm sounder and alarm light.
