Description

The invention relates to the field of mining and can be used in the construction of mining machines. Known reloader for the PK-9r combine (see "Roadheaders" by Ya.I. Bazer, V.I. Krutilin, Yu.L. Sokolov, Moscow: Nedra, 1974, pp. 158-159), consisting of a bridge loader and trailed loader. With its front end, the bridge crane is suspended by means of ball traction to the tail of the combine conveyor. At the rear end of the bridge crane, there is an eyelet for connecting to the sector of the ring support of the support carriage of the trailer crane.

The trailed loader is connected to the combine using chains. When the combine moves forward, the chains are pulled and pulled by the loader. When the combine moves backward within a meter and a half, the chains are loosened and the towed loading crane remains stationary.

A support trolley is mounted on top of the front drive section of the reloader, which moves along the rails within 1.5 meters.

The disadvantage of this technical solution is the design complexity and inconvenience during operation. The maneuverability of the combine is insufficient when working with this reloader, since when the combine moves backward, the distance of its movement is limited to 1.5 m, and when the combine is turned through a significant angle, the trolley can tip over from the guides. In addition, the design contains a large number of constituent elements, which greatly complicates it and makes it labor-intensive.

The closest technical solution adopted for the prototype is the Sigma loader VOA800 (see Sigma by A.O. Barak at 21-002 Yasktuv “Technical Operational Documentation” BOA 800 feeder system with serial No. 04/08 Barak, March 2008 .) containing a system of tape feeders. In the main embodiment, the feeder is connected on the side of the tail head with a roadheader, and on the side of the tension head is connected to another feeder by means of a rotary device.

The feeder is suspended on a monorail. The feeder system moves with the harvester as it progresses. The rotary device comprises a turntable assembly and a reverse plate. The rotary device provides rotation of the feeder at a given angle and limits the angle of rotation, slows down the movement with the help of two pivots and sheets of a certain shape in contact with the pivots. The disadvantages of the design of the rotary node is its complexity and the complexity of manufacturing, high metal consumption.

The objective of the present invention is to simplify the design, reduce metal consumption and labor costs for its manufacture.

The solution to this problem is achieved by the fact that the rotation angle limiter is made in the form of a screw mechanism, the screw of which is threaded in a fixed plate, and its end is located in the blind groove of the rotary plate, and the blind groove of the rotary plate is made in the form of a segment limiting the rotation angle of the short reloader and providing its braking.

Comparison of the claimed modular loader with the prototype allows us to conclude that the latter does not have features similar to the existing distinguishing features of the claimed modular loader:

- the limiter of the rotation angle is made in the form of a screw mechanism;

- the limiter screw with its threaded part is placed in a fixed plate, and the end is located in the blind groove of the rotary plate;

- the blind groove of the rotary plate is made in the form of a segment that limits the angle of rotation of the short reloader and ensures its braking.

The set of features of the claimed technical solution has a difference from the prototype and known analogues and does not follow explicitly from the studied prior art, therefore, the authors believe that the object is new and has an inventive step due to the fact that there is a combination of features, namely:

- the limiter of the rotation angle is made in the form of a screw mechanism;

- the limiter screw with its threaded part is placed in a fixed plate, and the end is located in the blind groove of the rotary plate;

- the blind groove of the rotary plate is made in the form of a segment that limits the angle of rotation of the short reloader and ensures its braking.

The invention has an inventive step and due to the fact that

- the limiter of the rotation angle is made in the form of a screw mechanism;

- the limiter screw with its threaded part is placed in a fixed plate, and the end is located in the blind groove of the rotary plate;

- the blind groove of the rotary plate is made in the form of a segment that limits the angle of rotation of the short reloader and ensures its braking.

These signs are interconnected so that when one of them is eliminated, the technical result achieved by the invention disappears. The invention is progressive and represents the next stage in the development of mining equipment, as it allows to simplify the design, reduce metal consumption and labor costs by using a screw mechanism in the limiter of the rotation angle.

The modular loading crane, in which the invention is claimed, can find wide application in the mining industry and other areas of the national economy, that is, it is an industrially applicable technical solution.

The achievement of the technical result during the operation of the modular loader is ensured by the fact that:

- the limiter of the rotation angle is made in the form of a screw mechanism;

- the limiter screw with its threaded part is placed in a fixed plate, and the end is located in the blind groove of the rotary plate;

- the blind groove of the rotary plate is made in the form of a segment that limits the angle of rotation of the short reloader and ensures its braking.

This ensures the movement of the rotary plate relative to the screw located in the blind groove at a certain angle. The essence of the claimed invention is illustrated by the accompanying drawings.

The drawings show:

figure 1 - General view of the modular loader;

figure 2 - General view of the rotary device;

figure 3 is a section along the axis of the rotary device;

figure 4 is a section along the axis of the screw mechanism;

5 is a rotary plate (bottom view).

The modular reloader consists of a short reloader (Fig. 1; 2) 1 connected by the front end to the mining machine 2 by means of a rotary device 3, and the rear end mounted on the monorail 4, a long reloader 5 suspended on the monorail 4, and a rotation angle limiter 6.

In this case, the short reloader 1 is connected to the long reloader 5 by means of a rotary device 7 having a fixed plate 8 rigidly connected to the long reloader 5 and a rotary plate (Fig. 3) 9, which enables the rotation of the short reloader (Fig. 1) 1 to a predetermined the angle and the associated horizontal axes (figure 3) 10.

The limiter of the rotation angle (Fig. 2) 6 is made in the form of a screw mechanism (Fig. 3) 11, the screw (Fig. 4) 12 of which is placed with its threaded part in a fixed plate (Fig. 2) 8, and the end (Fig. 4) 12 is located in the blind groove 13 of the turntable 9.

Moreover, the blind groove 13 of the rotary plate 9 is made in the form of a segment (Fig. 5) 14, limiting the rotation angle of the short reloader (Fig. 1) 1 in a certain sector and ensuring its braking.

The operation of the modular loader is as follows:

The repelled mass from the mining machine (Fig. 1; 2) 2 enters the short reloader 1, then to the long reloader 5, from which it is reloaded to vehicles. When the combine 2 moves backward, the modular loader moves along the monorail 4. During the rotation of the combine 2 left or right, the short loader 1, due to the rotary device 3 and the rotary device 7, also changes its position, limiting the angle of rotation of the short loader 1 in both directions relative to the longitudinal the axis of the combine 2, increasing the friction force of the end face of the screw (Fig. 4) 12 about the bottom of the blind groove (Fig. 4) 13, as a result of rotation, the screw (Fig. 4) 12 is screwed in, which allows to slow down the rotation speed of a short overload atelier (figure 1; 2) 1, without transferring force to the long reloader 5. Moreover, through the connection of the rotary plate (figure 3) 9 with a short reloader (figure 1; 2) 1 using the axis (figure 3) 10 moves a short reloader (figure 1; 2) 1 in a certain direction. The screw mechanism (figure 3) 11 serves to limit the rotation of the short reloader (figure 1; 2) 1 due to the screw (figure 4) 12, which is located at the end in the blind groove 13 of the rotary plate (figure 3) 9. The rotary plate 9 moves around the axis of rotation 15 of the rotary device (FIG. 2) 7, its segment (FIG. 5) 14 rests against the screw (FIG. 4) 12 and stops the movement of the short reloader (FIG. 1; 2) 1. To ensure smooth rotation short loader 1 (without sharp blows) the screw mechanism (figure 3) 11 slows down the rotation, since the screw (figure 4) 12, twisting, resting tsya in the bottom (5), a blind groove 16 (Figure 4) 13, which increases the friction force decreases and the travel speed.

The proposed reloader is modular due to the presence of a limiter made in the form of a screw mechanism, which allows to simplify the design, make it less time-consuming and provide ease of use.
