Description

Surface treatment device for rigid contact line

Technical Field

The application relates to the technical treatment field of rail power supply, in particular to a surface treatment device for a rigid contact line.

Background

The rigid overhead contact net is used as a low-clearance overhead contact net suspension mode, is introduced into Guangzhou subway second-number line operation from abroad for the first time in 2003, is convenient to maintain due to the simple structure, shows good usability in operation for many years, and is widely used in various large cities in recent years.

In actual operation, the rigid contact net often has the phenomena of poor elasticity of local sections, high contact line abrasion rate and uneven abrasion, and simultaneously has the problem of irregular abrasion of the carbon sliding plate of the pantograph of the electric bus. The irregular abrasion of the carbon sliding plate aggravates uneven abrasion of the contact line, worsens the bow net relation and has serious influence on the safe operation of the subway.

Contact line polishing is the most effective bow gateway system treatment measure at present, polishing coverage should be maximized, complete full line polishing in a short time in a concentrated manner, ensure that the contact net can reach the good technical state of no burr, no rough surface and no sharp side edges in the shortest time. Too long polishing period can not repair the contact net timely and comprehensively, the polishing repair speed of the contact line surface is far lower than the damage speed, the contact net can not play a role in optimizing the bow gateway system, and the repeated situation is easy to occur.

At present, two traditional schemes for polishing and polishing contact lines of a rigid contact net exist, namely, manual sand paper polishing is adopted, and nylon polishing wheels are used for manually polishing in combination with electric equipment.

The manual sand paper polishing method adopts coarse sand paper and fine sand paper to polish the contact line along the line direction, and operators use the coarse sand paper to polish the cutting, burr and arc-striking parts of the contact line, and fine sand paper polishes the contact line. The polishing machine has the advantages of fine polishing and low consumable cost; the defect of the polishing machine is that a large amount of manpower is required to be input, the operation intensity is high, the operation efficiency is low, potential safety hazards exist, the operation personnel can be scratched by burrs generated by contact lines, and the physical health of the operation personnel can be seriously damaged by a large amount of metal particles and dust generated in the polishing process.

The method for manually polishing by using the nylon polishing wheel and the electric equipment is characterized in that a hand-held chargeable polishing machine is adopted to replace sand paper for polishing: the polishing speed is high, and the efficiency is improved compared with the polishing speed; the defects are as follows: firstly, the machine is heavy, the height and the strength of hand-held polishing are difficult to control, if the operation is improper, the damage to the surface of a contact line and the personal injury can be caused; secondly, the polishing precision can not be mastered, and the normal contact line is easily damaged carelessly.

In order to solve the problems, chinese patent application (issued publication No. CN 208601227U) discloses a contact line polisher for a rigid contact net, which comprises a frame, a travelling mechanism and a polishing mechanism, wherein the travelling mechanism and the polishing mechanism are respectively arranged on the frame, the polishing mechanism comprises a polishing motor and polishing wheels which are driven to rotate by the polishing motor, the travelling mechanism comprises four pairs of travelling wheels arranged at four corners of the frame, the wheel surfaces of each pair of travelling wheels are opposite to each other and form a clamping part, the polishing wheels are arranged in the middle of the frame, and the axial direction of each polishing wheel is perpendicular to the axial direction of each travelling wheel so that the steering direction of each polishing wheel is perpendicular to the travelling direction of the frame; still install flexible motor in the frame, the telescopic link of flexible motor is vertical to be set up, the motor of polishing is installed on the telescopic link of flexible motor. The patent has the advantages that: design science, reduction manual operation, reduction intensity of labour, security are good, improve precision and efficiency of polishing, but this patent still has some shortcoming: because abominable tunnel environment and the extension of operation cycle, great arch or pit can appear on the surface of contact line, in the scheme of above-mentioned patent, the telescopic link vertical setting of telescopic motor, the motor that polishes for the drive wheel is installed on the telescopic link, make the wheel that polishes can only carry out vertical adjustment, when the wheel that polishes meetting the arch or come out from the pit, the wheel that polishes can receive the extrusion and descend gradually, and the extrusion that receives can increase gradually, cause the wheel that polishes resistance grow in advancing direction, can lead the telescopic link to rock so as to influence structural stability for a long time, and when the resistance grow in advancing direction, the wheel that polishes can hug closely more on the contact line, lead to polishing wheel and carry out excessive polishing in resistance great department, make the contact line inhomogeneous that polishes, influence polishing effect; in addition, the up-and-down movement of the polishing wheel is driven by a telescopic motor, and the telescopic motor is matched with the electric control, so that the structure is complex and the production cost is increased.

Moreover, the contact wire abrasion is uneven, such as uneven contact wire abrasion and raised contact wire bottom, which cannot be eliminated by polishing, and no good solution is available for the technical problems.

In addition, when the surface of the contact wire is processed by adopting the processing mechanism in the prior art, the contact surface between the travelling wheel and the bus bar in the travelling mechanism is often used as a reference surface for processing, the reference surface is positioned above the contact wire, and due to the assembly between the contact wire and the bus bar or deformation of the contact wire after long-term use, the distance between the lower surface of the contact wire and the reference surface is variable, the lower surfaces of the contact wires of different working sections are relatively close to the reference surface or far away from the reference surface, and the distance between the processing mechanism and the reference surface is relatively fixed, so that the contact wire relatively close to the reference surface cannot be effectively processed, and the contact wire relatively far away from the reference surface cannot be excessively processed, so that the contact wire is severely worn, and even the contact wire cannot be normally used.

In view of the foregoing, there is a need for developing a novel surface treatment device for rigid contact wires to solve the above-mentioned problems.
