Double Drum Winch Mill

Abstract

The invention discloses a double-drum winching machine. The double-drum winching machine comprises a base. An engine, a speed changing device, an external urgent braking device and a transmission system are arranged on the base, wherein the engine, the speed changing device, the external urgent braking device and the transmission system are sequentially connected in a transmission mode; a forward and backward gear mechanism is arranged at the portion, between the engine and the speed changing device, of the base; a torque limiter is arranged at the portion, between the speed changing device and the external urgent braking device, of the base; a first drum and a second drum are respectively connected to the power output end of the transmission system in a transmission mode. The double-drum winching machine is reliable in work, easy and convenient to operate, high in safety, good in braking performance and wide in application range; as the forward and backward gear mechanism is arranged, reversing is convenient, and it is guaranteed that forward traction and backward traction are same; when reversing is carried out, the forward state, the idling state and the backward state can be achieved only by operating a reversing rod, and operation is quite easy; as the torque limiter is arranged, overload operation can be effectively controlled, and overload accidents can be avoided.

Description

Technical field [0001] The invention belongs to the technical field of traction devices in freight ropeway transportation, and particularly relates to a double-drum winch mill. Background technique [0002] At present, transmission lines are developing in the direction of ultra-high voltage and ultra-high voltage. The tower body changes from low to high, tower materials from small to large, and towers go from prosperous areas into unmanned areas. The transportation volume of tower materials is increasing, and the transportation capacity is constantly improving. The previous human and animal transportation cannot A large amount of material flows in areas with complex conditions, especially in mountainous areas, woodlands and other areas, and ropeway transportation has become the first means of transportation for construction units. Some power transmission and transformation companies in my country have accumulated a lot of construction experience in this area. Simple freight rope...

Problems solved by technology

[0003] There are many kinds of existing winch mills or tractors. For example, the utility model patent No. ZL201520481388.1 discloses a mechanical tractor, whose direction is changed by the reversing mechanism on the gearbox. The gear is reversed, but the rotational speed of the reversed rotation is different from the rotational speed of the forward rotation after the reversing, so that the traction force required for the forward rotation and the reverse rotation is different. When the actual traction force is difficult to meet the current required traction force, it is easy to damage the equipment or cause Accidents, resulting in losses, and inconvenient operation; in addition, during the operation of the equipment, the torque is not limited, it may run under overload conditions, and overload accidents occur
