The invention relates to the technical field of drilling machine winch equipment, in particular to a control system for emergency lowering of a drilling machine traveling block, which comprises a right-way working clamp, a left-way working clamp, a safety clamp, an oil source, an oil tank and a manual oil supply pump module, the right-way working clamp is connected with the oil source and the oil tank through the right-way working clamp oil way; the left working clamp is connected with an oil source and an oil tank through a left working clamp oil path; the safety tongs are connected with an oil source and an oil tank through a safety tongs oil way and a manual pump oil way, and the safety tongs can be selectively connected with the safety tongs oil way and cut off the manual pump oil way or cut off the safety tongs oil way and connected with the manual pump oil way. The manual oil supply pump module is arranged on the manual pump oil way, so that an oil source supplies oil to the safety tongs through the manual oil supply pump module; under the condition of emergency braking of the traveling block, oil pressure can be provided for the safety tongs through the manual oil supply pump module, and emergency lowering of the traveling block is achieved by controlling the braking force of the safety tongs.

    本发明涉及钻机绞车设备技术领域,尤其涉及一种钻机游车应急下放的控制系统,包括右路工作钳、左路工作钳、安全钳、油源、油箱和手动供油泵模块;右路工作钳通过右路工作钳油路与油源和油箱连接;左路工作钳通过左路工作钳油路与油源和油箱连接;安全钳通过安全钳油路和手动泵油路与油源和油箱连接,安全钳可选择地与安全钳油路连接和手动泵油路截断,或者与安全钳油路截断和手动泵油路连接;手动供油泵模块设置在手动泵油路上,以使油源通过手动供油泵模块向安全钳供油;在游车紧急制动的情况下,通过手动供油泵模块能够提供油压给安全钳,并且通过控制安全钳的刹车力,实现游车的应急下放。
