Description

The present invention relates to the field of the mining industry, in particular to the equipment of branched tracks of suspended monorails, including underground and/or mine monorails.

In coal mines, in sectional trackless and conveyorized workings, as well as in development workings with blowing soil and having curvatures in the horizontal and vertical planes, it is advisable to use monorail roads.

The monorail track is made of I-beams and connected from sections 4-6 m long, suspended from the roof by chain hangers of adjustable length. Symmetrical turnouts with remote and manual control are installed on the track branches and turnouts (Pukhov Yu.S., Transport Machines: Textbook for Universities, 2nd ed., revised and enlarged, Moscow: Nedra, 1987, pp. 201-205).

Connecting monorails are used to connect curved sections of a monorail track with straight sections, as well as to connect with a fork switch.

On one side, the connecting monorail is welded with fastening elements of the rotary monorail - a flange and a loop for a bolted connection, on the other side, the fastening elements of the running monorail are welded - an eye, a lock or a key. In addition, the end with the eye and the fastening element - a lock or a key is made with a bevel in the vertical plane with an angle of 3.5º for a hinged-sliding connection with the running monorails.

During the movement and braking process of the rolling stock of a mine suspended monorail, dynamic loads arise on the support at the attachment points of the monorail, which can lead to its deformation and displacement along the mine workings (E.L. Ignatkina, A.V. Kostenko, Analysis of the support of the suspended track of a mine suspended monorail, Third International Scientific and Technical Conference "Technical Operation of Water Transport: Problems and Development Paths", pp. 83-86).

A switch is known that includes a supporting frame made of an I-beam, consisting of running, turning and connecting monorails with fastening elements. The fastening elements are made by welding on the output ends of the monorails.

The prior art discloses a switch for a suspended monorail track, comprising a frame with entry and exit monorails, a carriage with the possibility of parallel transfer of intermediate monorails, intermediate monorails, a drive for switching the exit monorail, the fastening elements are located at the ends of the monorails and are made as a single unit by welding. (Patent for Utility Model RU 136047 U1, published 27.12.2013)

During operation, significant physical loads are applied to the fastening units, which significantly reduces the useful life of turnouts.

The design of butt joints must ensure the ability to assemble a monorail track with gaps in the joints of the running surfaces of no more than 5 mm and misalignments of the running surfaces vertically and horizontally of no more than 3 mm. These requirements must also be met when closing turnouts. (Safety Standards for the Main Mining and Transport Equipment for Coal Mines. RD 05-325-99 as amended on 23.07.2002)

A common drawback of known devices is the lack of the ability to quickly repair individual fastening elements without completely dismantling the turnout.

The task set when creating the proposed bracket for the monorail transfer was to eliminate the above-mentioned shortcomings.

The technical result is the creation of a device of simple design, allowing for prompt repair work and replacement of a failed fastening unit, without completely dismantling the entire turnout.

The technical result is achieved in that the bracket for the monorail switch is a single welded structure containing a rail part, on the lower plane of which a support plate and a bushing are installed, on the upper plane of the rail part, at one end a fastening platform is transversely installed, having through holes, wherein the fastening platform is connected to the rail part through a bar, and at the other end of the rail part a trapezoidal flange is vertically installed, having different thicknesses along the height, as well as through holes, wherein the flange is connected to a stiffening rib.

The bracket for monorail translation is explained by the following drawings.

Fig.2 shows a side view of the bracket for the monorail transfer;

Fig.3 shows a top view of the bracket for the monorail transfer;

Fig. 4 shows a general view of the bracket for the monorail transfer;

It should be noted that the bracket for a monorail switch presented in this description does not limit possible design changes, combinations and modifications using solutions of the known level of technology within the scope and essence of the invention within the framework of the attached claims. Below is one of the possible embodiments of the device.

The bracket for the monorail switch is a single welded structure including a rail part 1, in the lower part of which there is a support plate 7 and a bushing 2. On the upper plane of the rail part 1 there is a bar 3 with a transversely located fastening platform 4 having through holes. In the plane of the end opposite to the fastening platform 4 there is a vertically installed flange 6 of a trapezoidal shape and having a different thickness along the height, as well as through holes, conjugated with a stiffening rib 5.

There is a variant of a bracket for a monorail switch (Fig. 5) for a track having a radial direction. In this variant of the bracket for a monorail switch, on the upper plane of the rail part 1 there is a fastening platform 4 mounted on a bar 3, with an installation angle of less than 90° relative to the axis of the rail part 1. Depending on the direction of movement of the track, the installation angle of the fastening platform 4 can also be more than 90° relative to the axis of the rail part 1.

There is also a variant of turnouts, when the bracket for the monorail switch (Fig. 6) has one or more additional ribs 8, and also in the upper and lower planes of the rail part 1, lugs 9 are installed. If there are 2 additional ribs, then a dimensional bar 10 is installed between them.

The monorail switch bracket works as follows. The rolling stock, moving along the monorail, approaches the switch and passes through the monorail switch bracket, for example, having a transversely installed fastening platform 4. Then, following the required route of movement, the rolling stock passes the switch and exits through the monorail switch bracket, for example, having a fastening platform 4 with an installation angle of less than 90° relative to the axis of the rail part 1. Then it exits onto a straight section of the track.

The bracket for the monorail switch itself, through the holes of the mounting platform 4, has a rigid fixation on the switch (not shown), for example, by a bolted connection, tightly pressing the rear end of the rail part 1 with the monorail of the switch. The presence of the bar 3 allows raising the mounting platform 4 above the upper plane of the rail part 1 for unimpeded movement along the rail tracks. The front end of the rail part 1 is related to the end of the rail road and fixed through the flange 6 and the bushing 2. To ensure the vertical position of the flange 6, there is a stiffening rib 5. There is also a support plate 7 designed to prevent deformation and accelerated abrasion of the lower area of the rail part 1.

Due to the fact that during the movement of rolling stock on rail tracks, the greatest load falls precisely in the area of rail joints, this area becomes unusable first of all, requires replacement and appropriate repair work. The declared bracket for the monorail switch has a removable mount, which allows you to easily and quickly carry out repair work, remove and replace only the device itself, without dismantling the entire switch.
