The present invention relates to the rail industry, and, more particularly, to a battery-operated tool for use in the rail industry.
Currently, there are no battery-operated spike drivers for the rail industry that provide adequate power for sustained use. There are also no tool configurations for the rail industry that enable a cordless battery-operated tool to be converted into a corded tool capable of performing tasks with a much higher power requirement, and vice versa. There is a need for a single tool capable of performing tasks requiring varying degrees of power without sacrificing the mobility provided by a tool powered using small rechargeable batteries. There is also a need for a system configured to safeguard the normal operation of a tool when utilizing a series of small rechargeable batteries connected in parallel or in series.
Aspects of this disclosure relate to a battery-operated tool (or device) for use in the rail industry. In various embodiments, the battery-operated tool may comprise a battery-operated spike driver configured to drive in spikes configured to hold rails for a railway onto a fixed point. In other embodiments, the battery-operated tool may comprise a battery-operated spike puller, a battery-operated tamper tool, a battery-operated packing tool, and/or one or more other types of tools that are battery-operated and configured for use in the rail industry. For example, in some embodiments, the battery-operated tool may be configured to receive one or more attachments that enable the tool to be one or more types of tools.
In various embodiments, the battery-operated tool may include or otherwise be connected to a battery management system. The battery management system may be configured to manage the power supplied to the battery-operated device via one or more batteries. In various embodiments, the one or more batteries may comprise a set of rechargeable batteries connected in series or in parallel. For example, the one or more batteries may comprise a set of 6 or 7 rechargeable batteries connected in series or in parallel. In some embodiments, the battery management system may be configured to cause the set of rechargeable batteries to run down one at a time. In some embodiments, the battery management system may be configured to automatically shut down the battery-operated device if a controller temperature exceeds a threshold temperature. In some embodiments, the battery management system may comprise an active battery equalization system configured to automatically shut off and disable one or more batteries when low voltage is detected. In some embodiments, the battery management system may be attached to or included within the battery-operated device. In other embodiments, the battery management system may be physically separate from the battery-operated device. For example, the battery management system may be included within a separate battery pack comprising the set of batteries and connected to the battery-operated device via a cord. In some embodiments, this separate battery pack may be located within a rolling device configured to move with the battery-operated device as the battery-operated device moves along the rails of a railway.
