Description

The invention relates to a rail transport device with a linear motor and can be used in the metallurgical industry for ingot loading, running, cleaning coils and moving other tons of cargoes, as well as in machine building and other industries as in-plant i and shop transport.

A rail transport device with a linear motor is known, in which the curvature of the inductor of the engine is increased compared with the gap on the straight sections, which allows the engine to pass freely through the gap of its inductor. However, an increase in the clearance of the inductor of the engine negatively affects its characteristics.

It is also known a transport device comprising moving a carriage along a track with a curvilinear section of a cargo trolley, a linear motor with stationary inductors with a main plate on a trolley, 2.

To facilitate the passage of the core plate, the inductor gap on curved sections of the path is hinged on the last. However, the position of the core plate with respect to the inductor on curved sections does not remain constant, which negatively affects the characteristics of the engine transport

10 devices.

The purpose of the invention is to simplify the design and increase the reliability of the transport device.

The goal is achieved

15 in that the curved section of the track consists of alternating straight and curved segments, the inductors are mounted on straight lines, the trolley is equipped with

20 with two carriages, and the root plate is made in the form of two sections, each of which is mounted on a corresponding carriage, and the distance from the inductor to the closest curvilinear segment of the path is equal to the half sum of the lengths of the core plate and the base of the carriage.

FIG. 1 shows a section of the track, top view; Fig.2 30 truck, end view. The cart 1 with rotary carriages 2, under which the sections of the main plate 3 of the linear motor are fixed, is mounted on the rail track 4, which on curvilinear sections consists of alternating; short curvilinear segments 5 and straight line segments 6. The inductor 7 of the linear motor is mounted on straight line segments. The magnitude of the angle f (Fig. 1, corresponding to the curvilinear segment 5) is determined from the condition of ensuring an acceptable radius of curvature 1 and the requirement to ensure constant transmission of the tractive force to the carriage, i.e., such that the output of the rear section of the main plate 3 from the working gap of the inductor would be accompanied by the entry of the front section of the plate into the working gap of the next inductor.At the work, due to the specific scheme of installation of inductors on the straight sections of the path, the required driving mode (braking, trolley braking. By changing the interval between stationary inductors, it is possible to ensure the transfer of traction force by inductors either directly to both sections of the base plate 3 fixed under the carriages 2 or to one. Transfer of the traction force to one section of the root plate is provided in sections of the path where the stopping of the cart is not required, this provides the necessary amount of tractive effort for movement at a given speed, as well as the possibility of acceleration with reduced acceleration. When the trolley moves on curvilinear sections, each of its pivoting carriages is provided for a straight line all the time while the core plate section is in the working inductor gap, which is determined by setting the inductor at a distance from the nearest curvilinear segment equal to the half sum of the base plate and base section carriages. After the release of the core plate section from the working gap of the inductor, the carriage, under which this core section is fixed, enters a curvilinear segment. At the same time, the core plate section fixed under the front carriage of the carriage is already in the gap of the next in the course of the movement of the inductor and overlaps it along the length necessary to provide the required pulling force. The total length of an inductor installed on a straight line segment between two curvilinear segments. must be greater distance between the sections of the core plate, fixed under the carriages of the trolley, by an amount that provides the necessary overlap of the inductor with the core plate and obtains the required value of the maximum force. The proposed device makes it possible to perform linear motor inductors with a minimum working gap without complicating the design, which provides an increase in the reliability and efficiency of the linear motor and, consequently, the transport device as a whole.
