Description

Technical field

A device for adjusting sectional insulators of a contact network is an invention, and relates to the field of electrification of railways, in particular to devices, specialized equipment with the help of which sectional insulators are checked and adjusted, the use of which will allow optimizing a number of production, technical and technological processes (reducing time losses for work on adjusting sectional insulators, errors of maintenance personnel when adjusting contact network devices are excluded, the organization of adjustment work is carried out without relieving tension and interrupting the movement of trains), which also increases labor productivity.

State of the art

No such device or technical solution is known from the prior art. Checking and adjusting the sectional insulators for continuity and straightness of sliding of the pantograph along the insulator was carried out using a wooden block, moving it along the trajectory of the pantograph and ruler. Under operating conditions, checking the smoothness of passage through the insulator is determined visually. Checking the dimensions of the groove for the contact wire of the insulating element and the insulating slide is carried out with go-through and non-go-through gauges. Established by the Interstate Standard GOST 34205-2017 and approved by the Interstate Council for Standardization, Metrology and Certification (IGS), and published by STI Standardinform 2019.

The disadvantage of the applied methodology and technology for checking and adjusting sectional insulators is that errors in adjustment cannot be ruled out, leading to increased wear and a reduction in the service life of individual elements of the sectional insulator with their subsequent replacement with new ones. There are risks of damage to the elements of the sectional insulator and the occurrence of failures in the operation of technical equipment, loss of time for their repair, and an increase in the time of train losses.

The solution to the technical problem of the claimed invention was to overcome the technical shortcomings inherent in analogues, which led to the need to create a new device that would ensure ease of manufacture, use, and high and reliable performance. The new device will allow optimizing production, technical and technological processes (loss of time for adjusting sectional insulators is reduced, errors of maintenance personnel when adjusting contact network devices are eliminated, the organization of adjustment work is carried out without removing voltage and interrupting the movement of trains), which also increases productivity labor. The arsenal of devices used during repair work is expanding both on the railway contact network of the Russian Railways JSC landfill, and on the contact network of enterprises of the urban transport complex operating vehicles using electric traction with electricity supplied through an overhead contact network.

Disclosure of the invention

The technical result of the claimed invention is: optimization of production, technical and technological processes (time loss for work on adjusting sectional insulators is reduced, errors of maintenance personnel when adjusting contact network devices are eliminated, the service life of individual elements of a sectional insulator is increased, the organization of adjustment work is carried out without removing the voltage and interruption in train movement); Also, the technical result of the claimed invention is to increase the electrical safety of personnel through the use of insulating materials.

The device for adjusting sectional contact network insulators consists of two detachable parts - the base (sliding plane) and the slider, made of insulating material and connected to each other via neodymium magnets. The base is made in the form of a rectangular plate with a neodymium magnet placed in the center, on the sides of which there are holes for alignment with the second part of the device - the slider. The slider is made in the form of a rectangular beam, in the center of which there is also a neodymium magnet, on the sides of which there are pins for alignment with the holes of the base, and on the same side there are guide grooves for installing the device on the tension insulators. On one side of the slide there is an internal cell to accommodate a bubble level in order to unify the device in terms of checking sectional insulators according to additional parameters.

The process of organizing the inspection of a sectional insulator and its elements is carried out as follows: the slider is installed on the tension insulators of the sectional insulator from above, and the base (sliding plane) is applied from below using neodymium magnets and centering holes and pins. Using the sliding plane, the device moves along the tension insulators of the sectional insulator to detect the presence of impacts and snags; if there are such comments, the arc extinguishing horns and other elements of the sectional insulator are adjusted. The provided installation of a bubble level makes it easier to adjust the sectional insulator in the sliding plane.

Adjustment work is organized without relieving tension and interrupting train movement. If it is necessary to stop work to allow a train to pass, the design of the device makes it possible to simply and quickly remove it from the sectional insulator. In the event of a non-standard situation, if for some reason the device was not removed from the tension insulators, this will not affect the occurrence of a failure in the operation of technical means (fractures of the elements of the sectional insulator, locomotive pantograph) and the safety of train traffic, which is ensured by the design feature - the lower plane is higher than the plane of sliding of the pantograph along the arc-extinguishing horns of the sectional insulator.

There are several features in the manufacture of the “Device for adjusting sectional insulators of a contact network”: The shape of neodymium magnets can be not only round, but also chosen by the potential manufacturer during industrial production.

The body of the base and slider can be made of either solid or hollow material to facilitate adaptation.

Carrying out the invention

The device for adjusting sectional contact network insulators consists of two detachable parts - the base (sliding plane) and the slider, made of insulating material and connected to each other via neodymium magnets. The base is made in the form of a rectangular plate with a neodymium magnet placed in the center, on the sides of which there are holes for alignment with the second part of the device - the slider. The slider is made in the form of a rectangular beam, in the center of which there is also a neodymium magnet, on the sides of which there are pins for alignment with the holes of the base, and on the same side there are guide grooves for installing the device on the tension insulators of the sectional insulator. On one side of the slide there is an internal cell to accommodate a bubble level in order to unify the device in terms of checking sectional insulators according to additional parameters.

The process of organizing the inspection of a sectional insulator and its elements is carried out as follows: the slider is installed on the tension insulators of the sectional insulator from above, and a base (sliding plane) is applied from below, which are fastened by means of neodymium magnets and centering holes and pins. Using a sliding plane, the device moves along the tension insulators of the sectional insulator in order to check and identify the presence of impacts and snags; if there are such comments, the arc extinguishing horns and other elements of the sectional insulator are adjusted. The provided installation of a bubble level makes it easier to adjust the sectional insulator in the sliding plane.

Adjustment work is organized without relieving tension and interrupting train movement. If it is necessary to stop work to allow a train to pass, the design of the device makes it possible to simply and quickly remove it from the sectional insulator. In the event of an unusual situation, if for any reason the device was not removed from the tension insulators, this will not affect the occurrence of a failure in the operation of technical means (fractures of the elements of the sectional insulator, locomotive pantograph) and the safety of train traffic, which is ensured by the design feature - the lower plane of the base of the device is higher than the plane of sliding of the pantograph along the arc-extinguishing horns of the sectional insulator.
