Description

Detailed Description of the Invention Technical Field The present invention relates to a wireless control device for a carrier device that reciprocates or rotates over a predetermined distance using a metal rail or metal wire, and particularly relates to a wireless control device that uses a metal rail or metal wire as an antenna. The present invention relates to a wireless control device that can be used as a cordless controller.

Prior Art Conventionally, as an example of conveyance equipment, in a tile hoisting machine, a cargo trolley runs on wheels on a metal ladder rail that extends to the roof, and is moved by an electric winch or an engine-equipped winch installed on the ground. It is designed to move back and forth between the ground and the roof by being pulled by a rolled-up metal wire via a pulley, but in order to control the luggage cart loaded with tiles by a control device installed on the ground. The limit switches installed at the bottom and top of the ladder must be connected to the control device by electrical cords, so there must be an electrical cord between the ground and the roof along the ladder. The work efficiency is poor because the electric cord has to be stretched and contracted every time the height of the ladder changes or the place where the tiles are lowered changes, and there are also restrictions on the length of extension and contraction of the ladder, and the electric cord may break. There were drawbacks such as being easy to use.

This also applies to other similar transport equipment, such as elevators, self-propelled track transport vehicles such as trolleys, and gondolas of fire ladder trucks.
In these systems, the moving equipment and fixed parts are connected by electrical cords, and as the equipment travels, the electrical cords also expand and contract, making the electrical cords prone to fatigue and reducing the distance traveled. There were drawbacks such as the addition of various restrictions.

Purpose The present invention has been made to eliminate the drawbacks of the prior art described above, and its purpose is to achieve reciprocating or turning motion using a metal guide member such as a metal rail or metal wire. By using a metal guide member as an antenna for a radio transmitter and a radio receiver, it is possible to control the running of transport equipment such as roofing machines, elevators, track transport vehicles, and gondolas of fire ladder trucks. The electric cord that runs along the guide member is no longer necessary in conveyor equipment such as equipment, making it cordless, eliminating the problems of fatigue and disconnection caused by expansion and contraction of the electric cord, and making it possible to freely set the travel distance of the conveyor equipment to be long or short, improving work efficiency. The objective is to improve the vehicle performance and driving performance. Another purpose is to connect the transmitter and receiver antennas using a metal guide member, which allows for a longer transmission distance even for weak radio waves, and to make it less susceptible to external radio interference. It is to do so. Another purpose is to make part of the control circuit cordless by using dry batteries as the power source for the transmitter, and to be able to arbitrarily select the control position. It is to be. Another object is to enable signal extraction even when a part of the control circuit is in motion.

This has the effect of completely eliminating the problems of fatigue and wire breakage caused by expansion and contraction of wires, and the travel distance of the transport equipment can be freely set to be long or short, which has the effect of improving work efficiency and running performance. . Furthermore, since the antennas of the radio transmitter and radio receiver are connected by a metal guide member, the transmission distance can be extended even with weak radio waves, and the antenna is less susceptible to interference from outside. Furthermore, by using a dry battery or the like as a power source for the radio transmitter, a part of the control circuit can be made cordless, which has the effect that the control position can be arbitrarily selected. Further, it is possible to obtain the effect that signals can be taken out even when a part of the control circuit is in motion.
