Problems solved by technology

This size is a bit bulky, so it is not very convenient to carry it on site
And this kind of driving can't move on wet or ice-covered running overhead lines

Embodiment Construction

[0040] As shown in FIG. 1 , the line trolley 10 of the preferred embodiment of the present invention is installed on a live wire 16 . The trolley 10 has three coplanar drag wheels 12 mounted on the same side of the wheel frame 14 . The drag wheels 12 are arranged alternately along a first major axis parallel to and above the energized wires 16 . The trolley 10 also has two coplanar pressure wheels 18 spaced along a second long axis parallel to and beneath the energized conductor. The pinch wheel 18 is installed on the wheel frame 14 on the same side as the drag wheel 12, and can be disassembled.

[0041] The pinch wheel 18 is preferably centrally located between the drag wheels 12 and has a smaller diameter than the drag wheel 18 .

[0042] The number of wheels and the configuration of mutual arrangement all can have other schemes, but this embodiment has the best experimental result.

[0043] In order to be suitable for various wire and cable diameters and to facilitate th...

Abstract

The trolley is equipped with three coplanar traction wheels spaced apart along a first longitudinal axis parallel to the live power line and thereabove. The trolley is also equipped with two coplanar pressure wheels spaced apart along a second longitudinal axis parallel to the line and thereabove. The trolley further comprises a traction motor for powering the traction wheels. Finally, the trolley includes a pressure system for maintaining the line pressed between the pressure wheels and the traction wheels, and a control system for controlling the motor. Said trolley has enhanced tractive power. Thus in operation, the trolley is driven along the line whatever the dimension thereof and / or climatic conditions. The invention also concerns a ice removing equipment mounted on the trolley for use on the live power line. The ice removing equipment comprises a clamp band adapted to be opened and closed around the live power line. The clamp band bears blades concentrically spaced and arranged to form a cone opening in the forward moving direction of the trolley.

Description

technical field [0001] This invention relates to an improved small vehicle known as a "line trolley" which can travel along power lines or overhead ground lines. [0002] The present invention also relates to an ice-breaking tool installed on a road vehicle. Background technique [0003] Known line drives are used to measure electrophysical and environmental parameters and to verify certain conditions of power lines installed between towers. [0004] Known line drivers are: US Patent No. 4,904,996 to Fevnandes; US Patent No. 5,901,651 to Boyol; and PCT Patent Application No. 94 / 18046 to Scott. [0005] The main problem with known line traffic is the difficulty in generating sufficient drag (pull or push) to move it along power lines, which are often made of steel or aluminum and come in various diameters, and the line paths are often wet and sometimes even With icy layers, the drag problem often becomes a matter of choice for its wheel material. [0006] One known known w...
