Abstract

The invention relates to a hydraulic loading-limit mechanical variable speed winch, and belongs to the field of hoisting equipment. The hydraulic loading-limit mechanical variable speed winch comprises a hydraulic control system, a quick-connecting high pressure oil pipe and a drawing head device. The drawing head device and the hydraulic control system are connected through the quick-connecting high pressure oil pipe. The drawing head device comprises a base, a steel wire rope guide device, a winching cylinder support frame, a hydraulic motor, a motor protecting frame, a variable speed transfer case, a winching cylinder, a locking device, a speed reducing mechanism and a gear change hand lever. The steel wire rope guide device is installed on the base. The hydraulic motor is fixed to the variable speed transfer case. The motor protecting frame is arranged outside the hydraulic motor. The variable speed transfer case is fixed to the base and connected with the speed reducing mechanism, and the gear change hand lever is arranged on the variable speed transfer case. The speed reducing mechanism is installed inside the winching cylinder, and the cantilever end of the winching cylinder is supported by the winching cylinder support frame. The winching cylinder support frame is locked through the locking device and fixed to the base. The hydraulic loading-limit mechanical variable speed winch is reasonable in structure, convenient to operate, low in cost, safe and reliable.

Description

technical field [0001] The invention relates to a winch mill, in particular to a hydraulic load-limiting mechanical variable-speed winch mill, which belongs to the field of electric construction machinery lifting equipment. Background technique [0002] With the development of the power system, more and more power transmission and transformation lines are erected and transformed. In the construction and maintenance of the line, it is usually necessary to use special construction equipment to achieve traction, line tightening, vertical poles, vertical towers and equipment hoisting etc. Among all special construction equipment, the winch is widely used in electric power construction due to its light weight, convenient handling, simple operation, and no need for external power supply. [0003] As we all know, the most widely used motorized winch is a purely manual operation device, which is powered by a gasoline or diesel engine, and its manual clutch realizes the separation an...
