[0002] In metallurgical enterprise production, overhead travelling crane is widely used in molten steel lifting as an important hoisting equipment. Large-tonnage overhead travelling crane generally uses 3kV sliding contact line power supply, and the sliding contact line is a key component for overhead travelling crane power supply, and its surface state directly affects the stability and reliability of overhead travelling crane power supply.

[0003] During long-term use, oxidation layer and wear flash are generated on the contact surface of copper body sliding contact line and collector slider due to current, dust pollution, friction and other factors, especially the flash is the most harmful. The flash will fall off due to continuous thinning caused by friction. Since the flash of sliding contact line is copper material, the copper wire of flash is easy to short circuit from the upper phase fire line to the lower phase fire line during the falling process, causing inter-phase short circuit, arc discharge and causing serious power failure, which affects safety and production.

[0004] At present, the polishing and cleaning work of sliding contact line mainly adopts the way of regular manual polishing. This way has the following problems:

[0005] (1) The maintenance cycle is short, the polishing operation is frequent, and the labor is large;

[0006] (2) After power off, personnel climb up the sliding contact line to polish, and the personnel have high risk in high-altitude contact power conductor operation;

[0007] (3) The power-off range is large, the whole-span overhead travelling crane cannot be lifted and operated, the continuous production will be forced to stop, and the production efficiency is seriously affected;

[0008] (4) The range of each power-off polishing is limited, and the power-off, polishing, power-on, moving overhead travelling crane, power-off polishing need to be repeated until the whole-span sliding contact line is polished, which is low in efficiency.

[0009] Therefore, it is of important practical significance to develop a device capable of cleaning the flash of 3kV overhead travelling crane sliding contact line online. UTILITY MODEL CONTENTS

[0010] The utility model aims to provide a kind of overhead travelling crane sliding contact line track sweeper, which is installed on the sliding block of overhead travelling crane line relay, and can polish and clean the sliding contact line online during normal walking of overhead travelling crane, remove the flash on the end face, avoid power failure caused by flash short circuit and grounding, and solve the problems in the background technology.

[0011] The technical solution of the utility model is:

[0012] The utility model relates to a kind of overhead travelling crane sliding contact line sweep rail device, including sliding contact line relay, relay slider, sliding contact line, steel wire clamping plate, sweep rail steel wire and mounting bracket, sliding contact line relay is slidably connected on sliding contact line by relay slider, mounting bracket is fixed on relay slider, sweep rail steel wire is fixed on mounting bracket by steel wire clamping plate, and sweep rail steel wire cooperates with sliding contact line.

[0013] The sweep rail steel wire is two, and the two sweep rail steel wires are pressed on the edge of the end face of the sliding contact line by their own elasticity.

[0014] The sweep rail steel wire is arc-shaped and cooperates with the edge of the end face of the sliding contact line.

[0015] The mounting bracket is L-shaped, with a long side fixed on the relay slider and a short side clamping the sweep rail steel wire by the steel wire clamping plate.

[0016] The long side of the mounting bracket is provided with a bolt hole, and the long side of the mounting bracket is connected with the relay slider by a bolt and the bolt hole.

[0017] The distance between the two sweep rail steel wires is less than the width of the end face of the sliding contact line.

[0018] The utility model has the advantages that:

[0019] (1) the edge of the end face of the sliding contact line can be polished online during normal operation of the overhead travelling crane, copper burrs can be effectively cleaned, and power accidents caused by burr falling can be avoided without stopping the machine, thereby avoiding the impact on production efficiency caused by machine maintenance.

[0020] (2) the angle of the steel wire is adjusted by the clamping plate to ensure consistency and stability of polishing effect, and since the steel wire only acts on the edge of the end face of the sliding contact line by elastic force, the force is not large, only acts on weak burrs, and avoids excessive wear of the sliding contact line.

[0021] (3) the mounting bracket is designed reasonably, the installation process is simple and fast, and the mounting bracket is convenient to install and use on different types of overhead travelling crane sliding contact lines. BRIEF DESCRIPTION OF DRAWINGS
