Description

Technical field

The utility model relates to equipment for the mining industry, in particular, it can be used in the nodes of the connection of the sections of the gutter scraper conveyors.

State of the art

The prior art device for connecting the pans of the scraper conveyor, containing pads fixed in the hollows on the outside of the sides of the pans of the pans, in the sockets of which there is a connecting rod made with heads and a shank mounted on one of the heads of the connecting rod, and a stop element for fixing from the axial moving the connecting rod and the latch, which is made in the form of a c-shaped bracket, covering the shank of the connecting rod and mounted on it by means of a pin, and the stop element is made in the form of a rib with a recess for accommodating the shank of the connecting rod [1].

The disadvantages of this design are:

1) difficulty in manufacturing;

2) inconvenience of installation, as additional space is needed along the axis of the pan.

The prior art device is taken as the closest analogue for connecting the scraper conveyor chutes, including a connecting roller with heads interacting with a locking element, located in the profile recesses of the side walls of the pan sections, symmetrically with respect to the connector line, while the profile recesses are made with ring channels and centering conical surfaces at the ends for the heads of the roller, which has a cylindrical supporting portion in the middle, conical heads at the ends and ki, clenched locking elements are designed as spring-loaded ring with an opening arranged in annular grooves of profile grooves. The annular channels are made with stops [2].

The disadvantages of this design are:

1) the complexity and high cost of manufacturing its parts, for example, spring-loaded rings or conical surfaces of the heads of the connecting roller, which requires special materials, processing technology;

2) the complexity of installation, in particular if replacement is necessary, since the installation of connecting rollers with cone-shaped heads interacting with the locking element is possible only with open pans, which is very problematic when the conveyor is assembled, because this, in turn, requires opening the scraper chains, which entails additional costs.

A task

To simplify the design of the junction of the sections of the gutter of the scraper conveyor, which will ensure its quick and convenient assembly / disassembly.

As a result of solving the problem, a technical result can be obtained, which consists in simplifying the design of the node 35, while ensuring a high-quality connection.

Consumer properties: reduced costs for the manufacture and installation / dismantling of sections of the gutter of the scraper conveyor.

Utility Model Disclosure

The solution to this problem is achieved by the fact that in the already known node for connecting sections of the gutter of the scraper conveyor, including a connecting element made with heads, one of which is equipped with a shank connected by a supporting section, and placed in a channel opened by a through groove, which is formed by longitudinal coaxial holes made in the protrusions on the side walls of two adjacent sections of the gutter, a latch, which is made in the form of a bracket mounted on the shank of the head of the connecting element with the possibility of in the longitudinal direction of the retainer with a stop element, which is mounted on the side wall of one of the sections of the gutter, in accordance with the utility model, it is proposed:

- on the supporting section of the connecting element, parallel to its longitudinal axis, make a flat cut, on which, adjacent to the head with the shank, perpendicular to the longitudinal axis of the connecting element, perform a step protruding above the cutting surface, conjugated by its outer side surfaces with the inner side surfaces of the through groove with the possibility of fixation in the latter of the connecting element, wherein the height of the cross section of the support portion along a flat cut is less than the width of the through groove;

- the supporting section is cylindrical with an additional flat cut, which is parallel to the first flat cut;

- parallel to the flat sections on the supporting section equidistant from the longitudinal axis to perform flat sections on the cylindrical heads of the connecting element.

The causal relationship between the newly introduced essential features and the claimed technical result is explained as follows. The execution on the supporting section of the connecting element, parallel to its longitudinal axis, of a flat cut with a step protruding above it perpendicular to the longitudinal axis, which is adjacent to the head of the connecting element, makes it possible to simplify the design of the connecting element, and, accordingly, the surfaces of the knotted parts of the assembly. Eliminates the need for precision conical or inclined surfaces in mating pairs of parts. In this case, a flat cut, and even two, as in the example, with a cross-sectional height shorter than the width of the through groove, allows maintenance personnel to slide the connecting element into the coaxial annular channels on the side walls of two adjacent sections of the trough and rotate them 90 °, which simplifies assembly / disassembly of the junction of the connection sections of the gutter.

The step, acting above a flat cut, forms the outer side surfaces, which fixes the connecting element in the inner side surfaces of the through groove present in the protrusions of two adjacent sections of the conveyor groove, eliminating the possibility of rotation of the connecting element. At the same time, in the prototype, the connecting element has the ability to rotate in the channels under the action of shock loads, which requires the manufacture of the element and its mating parts from wear-resistant materials.

The adjacency of the step to one of the heads of the connecting element allows you to reduce the distance required to shift the connecting element along the groove during assembly / disassembly. This distance is determined by the width of the step, which is selected depending on the operating conditions of the conveyor, respectively, only the support part of the connecting element is extended by this amount. Thus, the combination of features ensures the achievement of a technical result: simplification of the design of the site.

The technical solution is illustrated by an example, the implementation of which is not the only possible, but clearly demonstrates the possibility of achieving the technical result of the proposed new set of essential features.

Industrial applicability

The implementation of the proposed technical solution is as follows.

The junction of two adjacent sections (1) and (3) of the groove of the scraper conveyor includes a connecting element (2) installed in the protrusions (1.2) and (3.2) on the side walls of two adjacent sections (1) and (3), a latch (4) made in the form of a bracket mounted on the shank (2.2.1) of the head (2.2) of the connecting element (2), and a thrust element (5), which is mounted on the side wall of one of the sections (3) of the groove (Fig. 1, 2) .

The connecting element (2) (Fig. 3), which is made cylindrical in the form of a body of revolution for ease of manufacture, has heads (2.2) and (2.3), which are coaxially (Y) connected by the supporting section (2.1). One of the heads (2.2) is equipped with a shank (2.2.1) with a through hole (2.2.4). Along the length of the entire supporting portion (2.1) of the connecting element (2), parallel to its longitudinal axis (Y) and parallel to each other, two flat sections (2.4) and (2.6) are made, in the example, equidistant from the axis (Y), although for implementation Utility model is enough to perform one flat cut. On a flat cut (2.4) adjacent to the head (2.2) with a shank (2.2.1), a step (2.5) protruding above the cut surface (2.4) is made, which has two outer side surfaces (2.5.1) and (2.5.2 ) Each head (2.2) and (2.3) is equipped with parallel to each other and parallel flat sections (2.4) and (2.6) of the support section (2.1), sections (2.2.3) and (2.3.1), which are made so that the heads do not advocated the overall dimensions of the sections (1) and (3) of the trough after installing the connecting element (2). On one of the heads (2.2) or (2.3) perpendicular to the flat cut (2.2.3) or (2.3.1), a through technological hole (2.2.2) is made (Fig. 3).

On the side walls of two adjacent sections (1) and (3) of the trough, protrusions (1.2) and (3.2) are made, which can be, for example, welded, cast together with the sidewall, etc. The protrusions (1.2) and (3.2) have holes ( 1.1) and (3.1), each of which is opened with a through groove of the same width (L). During the assembly of sections (1) and (3), the troughs are installed in such a way that the holes (1.1) and (3.1) form a common channel (X), and the through grooves in them form a common through groove (7) of a certain width (L) , which is greater than the height of the cross-section (h) of the support section (2.1) with a flat cut of the connecting element (2) by an amount necessary and sufficient for passage through the groove (7) of the support section (2.1) (Fig. 4, 5).

The latch (4) is made in the form of a bracket and is mounted on the shank (2.2.1), after which it is fixed on it with a stop (6) through the hole (2.2.4).

The stop element (5) in the form of a flat sheet is rigidly mounted on the side wall of one of the sections (3) of the trough to provide the stop of the lock (4).

The assembly of the connection unit of the sections (1) and (3) of the trough of the scraper conveyor is carried out in the following sequence. Two adjacent sections (1) and (3) of the grooves of the scraper conveyor mate with each other by the protrusions (1.2) and (3.2) until a channel (X) common to them is formed with a common through groove (7) of width (L). Then, in the holes (1.1) and (3.1), a connecting element (2) is installed, having previously been deployed with its head (2.2) with a shank (2.2.1) in the direction of the stop element (5). Then, the connecting element (2) is deployed so that the planes of the two sections (2.4) and (2.6) are parallel to the inner side surfaces (L ₁ ) and (L ₂ ) of the through groove (7). Since the cross-sectional height (h) of the support portion (2.1) with a flat cut of the connecting element (2) is made smaller than the width (L) of the through groove (7), the connecting element (2) passes through the groove (7) and enters the channel (X ) Then the connecting element (2) is rotated 90 °, thus securing it against falling out through the through groove (7). For ease of rotation of the connecting element (2) through 90 °, a through technological hole (2.2.2) is used, into which the rod is inserted and rotated around the axis (Y) to the desired position. During these operations, the step (2.5) protruding above the cut plane (2.4) is outside the channel, and only after the connecting element (2) is rotated 90 ° by movement along the channel axis (X), the connecting element (2) is positioned so that the stage (2.5) ) with its outer side surfaces (2.5.1) and (2.5.2) mated with the inner side surfaces (L ₁ ) and (L ₂ ) of the through groove (7), fixing it against possible rotation around its axis (Y) and, accordingly, loss of the connecting element (2).

After installing the connecting element (2) in the channel (X) on the shank (2.2.1) put on the latch (4), made in the form of a bracket, combining the longitudinal axis of the holes in the latch (4) and on the shank (2.2.1), in which then the stopper (6) is inserted. The latch (4) in the longitudinal direction interacts with the stop element (5), thus preventing the connecting element (2) from longitudinal displacement and from the exit of the outer side surfaces (2.5.1) and (2.5.2) of the step (2.5) from the interaction with inner side surfaces (L ₁ ) and (L ₂ ) of the through groove (7) and, accordingly, from falling out.

The junction of sections (1) and (3) of the trough of the scraper conveyor is very simple and quick to assemble and provides reliable fixation of the sections 5 of the trough. Dismantling the junction of sections (1) and (3) of the trough of the scraper conveyor is carried out in the reverse order.
