Miniature tractor

Abstract

The invention discloses a miniature tractor, which is mainly applied to the traction of a guiding rope in the initial stage of erection of a power transmission line. The miniature tractor comprises a grinding wheel mechanism, a control mechanism and a disk wheel for collecting the guiding rope. The control mechanism is connected with a power source through an oil pipe and a rapid joint, and comprises a control valve I, a hydraulic motor I, a control valve II and a hydraulic motor II. A small gear is arranged on an output shaft of the hydraulic motor I. The grinding wheel mechanism comprises a pair of grinding wheels. A large gear meshed with the small gear is arranged on the inner side of each of the two grinding wheels. Grooves for winding the guiding rope are formed on the outer circle of each grinding wheel. A guide wheel group is arranged at each of two positions opposite to an outlet groove and an inlet groove. The disk wheel is driven by the hydraulic motor II. The miniature tractor is small in volume, simple in structure and low in energy consumption. The power source is divided into independent parts so as to be conveniently transported in a mountain region. The miniature tractor is convenient to mount, and when other large-sized equipment is not arranged in place, the traction of the guiding rope can be started by the miniature tractor.

Description

technical field [0001] The invention relates to a traction machine, in particular to a special miniature traction machine for erecting transmission lines and laying out primary guide ropes. Background technique [0002] In the construction of transmission lines, wire erection construction is one of the most critical construction processes, and the deployment of guide ropes is the main content of this construction process. At present, more and more power parachute light aircrafts are used to release the guide ropes. After the powered parachute light aircraft is released to the line tower, it needs to be towed by a tractor. The existing tractor unit is not only bulky, complex in structure, cumbersome to install and debug, and takes a long time, which seriously affects the construction period; it is also complicated to operate and requires professionally trained personnel to operate. More importantly, the traction unit itself has high energy consumption, and the traction prim...

Problems solved by technology

For the new type of line, that is, the compact line, the conductor adopts a six-split structure, that is, each phase conductor is composed of six sub-conductors. For this kind of line that needs to deploy multiple primary guide ropes, the powered parachute light aircraft can only be divided into batches. Paying out wires requires long working hours, low efficiency, and high costs. If the weather changes and you cannot fly, the construction period will be extended. Using the traction unit to pull the leading rope will not only increase the rental cost, but also increase fuel consumption.
