Description

The utility model belongs to mining engineering and can be used in cleaning combines for underground mining.

From the state of the art, a holder for a track chain of a cleaning combine is known, which contains a body with an opening for water supply, located in its lower part, while in the opening there is a fitting connected to a pipeline sleeve, the working part of which is located in a track chain, connected with a holder, the hole for water supply is made on the bulkhead side of the holder body, the axis of the hole is perpendicular to the direction of movement of the cleaning combine, and a swivel sleeve is installed on the fitting, with the help of which it is connected to the pipeline sleeve (11.

The disadvantage of this design is that the holder is part of the hydraulic system of the cleaning combine.

This requires additional sealing of hydraulic connections located in it.

From the state of the art, a holder for a cable chain of a cleaning machine is known, taken as the closest analogue, which contains a support lever connected to the body of the cleaning machine by a bolted connection, to the lugs of which a half-pipe is hinged with the possibility of rotation with respect to the body of the cleaning machine on these hinges. Two oval rings are put on the half-pipe with the possibility of rotation around it, but limited in movement along it. Oval rings on one side of the oval hang on the half-pipe, and on the opposite side are provided with protrusions in the form of an ear, to which a link of the track chain is attached. Inside the half-pipe, a hydraulic supply and discharge system is installed in the form of a tubular part with the possibility of its rotation around its longitudinal axis, which reduces the risk of damage to the cable chains of the cleaning machine. Also, all hydraulic hose connections are made with the possibility of rotating the ends of the cables fixed in them (21.

The disadvantages of the design of the closest analogue are the following: 1) the holder is a part of the hydraulic system of the cleaning combine, to which the places of connections of hydraulic hoses converge, which are most prone to damage risks. Such a holder requires additional sealing of hydraulic connections located in it, additional attention and maintenance; 2) rotation of the half-pipe in the hinges of the support bracket can only be carried out upwards by a few degrees, because then the half-pipe rests against the body of the cleaning machine; 3) rotation of the hydraulic supply and discharge system in the form of a tubular part located

From the inside of the half-pipe, limited by the longitudinal surfaces of the half-pipe, against which the cable chains connected to the tubular part abut when turned; 4) free-hanging oval rings can be skewed when changing the movement of the cleaning machine and form "loops" etc. with the cable layer.

Thus, in general, the holder for the cable chain of the cleaning machine, according to the closest analogue, is part of the hydraulic system and remains extremely sensitive to uncontrolled mechanical loads, which are difficult to avoid during the operation of the cleaning combine, in particular, when changing the direction of movement of the cleaning machine.

The useful model is based on the task: to exclude the holder of the cable layer from the hydraulic system of the combine, leaving behind it only the function of laying hydraulic cables in the chute of the cable layer, which is safe for the places of connection of hydraulic hoses to the cleaning combine.

Solving this problem will allow to obtain a technical result, which consists in ensuring the maximum maneuverability of the cable laying holder, which ultimately allows securing the place of attachment of hydraulic cables.

Achieving the declared technical result provides the technical solution with consumer properties: reducing the risk of damage to hydraulic cables and improving the state of safety equipment.

In the already known holder (1) of the cable layer (3) of the cleaning combine (2), which contains at least one support bracket (4) installed on the body of the cleaning combine (2) and protruding towards the chute (3.1) for the cable layer (3), connected to the crossbar (5), on which the central lever (b) is fixed, the free end of which is provided with a protrusion (6.1) with a lug (6.3) at the end, with the possibility of connecting to the last cable layer (3), according to the technical solution, it is proposed: support connect the bracket (4) with the crossbar (5) with at least one side lever (4.1), hinged (4.2) and (4.3) connected to each of them, the central lever (6) on the crossbar (5) fasten on the axis ( 7) with the possibility of full rotation around it, and the eyelet (6.3) should be fixed on the bushing (6.4), which is used to provide the protrusion (6.1) of the central lever (6), with the possibility of rotating it together with the bushing (6.4) around the longitudinal axis of the latter.

In addition, it is suggested: - the protrusion (6.1) with the lug (6.3) at the end should be made in the form of an axis and placed perpendicular to the plane of the central lever (b);

- fix the central lever (b) on the crossbar (5) on the axis (7) with the possibility of rotation around it in a plane parallel to the direction of movement of the cleaning combine (2); - provide the central lever (b) with a locking element (6.2) with the possibility of fixing the central lever (6) on the crossbar (5); - parallel to the support bracket (4), which protrudes towards the cable layer (3), on the body of the cleaning combine (2), install the second support bracket (9), also connect it to the crossbar (5) with the side lever (9.1), which is hinged ( 9.2) and (9.3) to combine with each of them; - on each support bracket (4) and (9), in parallel with the side levers (4.1) and (9.1), install additional side levers (4.4) and (9.4), which are hinged to the corresponding support bracket (4) or (9) and crossbar (5).

The causal relationship between the newly introduced essential features and the declared technical result is explained as follows. The execution of the central lever on the crossbar on the axis with the possibility of rotation around it allows you to safely change the direction of movement of the cable layer during the turn of the cleaning harvester, while the eye fixed on the bushing, which provides the projection of the central lever, with the possibility of rotating the bushing around its axis, allows always under under the action of the cable layer's own weight, the bushing with the eye rotates to the lower position, thus lowering the hydraulic cables, which prevents their damage.

The central lever, together with the eye on the sleeve, is mounted on a crossbar, which also has the possibility of movement, which provides at least one side lever, which hinges the crossbar with a support bracket fixed to the body of the cleaning combine.

The lever ensures the raising and lowering of the crossbar and at the same time changing the location of the lug on which the cable layer is fixed, relative to the axis of the chute, while the crossbar is always in a vertical position, ensuring the operation of the central lever and the lug on the sleeve, to which the cable layer is directly attached. The possibility of vertical movement of the crossbar up eliminates the jamming of the central lever at the moment of turning the cleaning combine, and also eliminates the possibility of breaking the support brackets.

The provision of the claimed technical solution of the technical result, namely, the maneuverability of the holder of the cable layer, allows you to secure the place of attachment of hydraulic cables, somehow transfer it from the holder to the body of the cleaning combine and turn off the holder

From the cable layer of the hydraulic system of the combine, which in turn provides consumer properties: reducing the risk of damage to hydraulic cables and improving the state of safety equipment.

The essence of the technical solution is represented by drawings, where: - in fig. 1 shows a side view of the cable laying holder; - in fig. 2 shows a top view of the cable holder; in fig. C shows a view directly on the holder of the cable layer and the place of attachment of hydraulic cables on the body of the cleaning combine; - in fig. 4 shows the holder of the cable laying assembly; - in fig. 5 shows the holder of the cable layer during the movement of the cleaning combine; - in fig. 6 shows the holder of the cable layer when changing the direction of movement of the cleaning combine; 1 - holder; 2 - cleaning combine;

The implementation of a useful model is shown (fig. 1, 2, 3, 4, 5, 6) using an example that is not the only possible one, but clearly demonstrates the possibility of achieving a technical result.

The holder (1) of the cable layer (3) of the cleaning combine (2) is installed on the combine from the side of the chute (3.1) for the cable layer (3) and fixed with a removable connection (fig. 1).

In the example, the holder (1) is two support brackets (4) and (9) (Fig. 2), to which the side levers (4.1) and (9.1) are hinged (4.2) and (9.2), which in turn are hinged ( 4.3) and (9.3) are connected to crossbar (5). For the rigidity of the structure and the reliability of its operation, the support brackets (4) and (9) are equipped with additional side levers (4.4) and (9.4), which are also hingedly connected to the support brackets (4) and (9) themselves, and to the crossbar (5). Thus, a pair of side levers (4.1) and (4.4) forms a hinged parallelogram on the support bracket (4), and a pair of side levers (9.1) and (9.4) forms a hinged parallelogram on the support bracket (9) (Fig. 4). Thus, the system of hinged parallelograms ensures raising and lowering of the crossbar in the vertical plane (5) and simultaneously changing the location of the lug (6.3), on which the cable layer (3) is fixed, relative to the axis of the chute (3.1).

In the center of the crossbar (5) on the axis (7), with the possibility of rotation around it, a central lever (6) is installed, the free end of which is provided with a projection (6.1) in the form of an axis. At the end of the projection (6.1), a sleeve (6.4) with the possibility of rotation around its axis (8) is installed, into which an eyelet (6.3) is inserted in the form of a bracket with threaded ends, which are fixed with nuts (10).

Thus, the cable holder (3) fixed in the lug (6.3) has the ability to rotate around the axis (8) of the protrusion (6.1) and simultaneously with the protrusion (6.1) around the axis (7) of the central lever (6) during the movement of the cleaning harvester ( Fig. 4).

Hydraulic cables (11) are led inside the cable layer (3), leaving enough long ends for their stationary connection to the body of the cleaning combine (2). The distance (I) between the place of stationary attachment of the cables (12) to the body of the combine (2) and the lug (6.3), on which

A cable layer (3) is attached to it, choose a length of at least half of the arc of the circle of the allowable bending radius of the cable (Fig. 3, the chute (3.1) is conditionally not shown).

The holder (1) of the cable layer (3) of the cleaning combine (2) works as follows.

During the movement of the cleaning combine (2) in the Mi direction (Fig. 5, the central lever (6), which is made with the possibility of rotation around the axis (7), turns on this axis in the direction opposite to the Mi direction of movement of the cleaning combine (2), and in the future, it tries to take a horizontal position. In this position, if necessary, the central lever (b) can be fixed with a locking element (6.2). At the same time, under the influence of the weight of the cable holder (3), attached to the eyelet (6.3) in the form of a bracket, the cable holder (3) ) together with the sleeve (6.4) turns around the axis (8), taking the most convenient and safe position in the chute (3.1).

Side levers (4.1) and (9.1) and additional side levers (4.4) and (9.4) are hingedly connected to the crossbar (5), on which the central lever (b) is fixed, and are in the lower position (Fig. 1 ).

After reaching the end of the bench, the cleaning combine (2) makes a U-turn and changes the direction of movement to Me (fig. b6). At this moment, the central lever (b) goes down under its own weight and the weight of the cable layer (3) and turns 180", while the locking element (6.2), if it was installed, is in the position of free rotation of the central lever (6). After turning the central lever (b) in the opposite direction of movement of M2 of the cleaning combine (2), it tries to take a horizontal position, and the cable layer (3) together with the sleeve (6.4) turns around the axis (8), taking the most convenient position in the chute (3.1) and a safe position. The system of hinged parallelograms from the side levers (4.1) and (9.1) and additional side levers (4.4) and (9.4), hinged to the crossbar (5), on which the central lever (6) is fixed, is in in the lower position, while the crossbar (5) is in a vertical position. In the event of the formation of several, for example three, layers of the cable layer (3), the system of hinged parallelograms moves the crossbar (5) upwards, which eliminates jamming of the central lever (6) when turning the cleaning combine (2), and also eliminates the possibility of damage to the support brackets (4).

The given information confirms the possibility of industrial implementation and industrial application of the cable laying holder of the claimed cleaning combine. (510)
