Description

Technical field

The utility model relates to mining engineering and can be used in the lining of the pair of lava with excavation.

State of the art

Known as an analogue support for interfacing for work in workings that are stored for reuse, including the main section and the auxiliary section, the beam of which is included in the base of the main section, on which spacers, tops with movable and fixed supports are installed, the sliding mechanism with hydraulic jacks spacers mounted turret, pivotally connected to the rotary frame and equipped with a beam (table) with four racks resting on the base of the main rack [1].

The disadvantage of this analogue is the need to use additional labor and materials to adjust the height of the drive head of the conveyor using additional supporting elements (spacers).

The basis for creating a technical solution is the task:

- to provide the ability to remotely adjust the position of the drive head of the conveyor, the amount of soil erosion;

- optimize the adjustment of the positioning height of the table, with the conveyor drive placed on it,

When fulfilling the technical task, a technical result can be obtained: improving safety, tuning efficiency and operation of the mechanized complex.

Disclosure of a technical solution

The solution to this problem is achieved by the fact that in the section of the support lining, the base of which is supported by the struts of the table, on which the rotary support is installed, the table adjustment racks, as well as the two-linker and at least one four-link, additionally introduced into the section, are articulated with the table and the base of the section, with the four-link and two-link being placed in the form of a pantograph, and perform their articulated joints with the table and the base of the section each with two fulcrum.

Thus, new in the claimed technical solution is that:

the table adjustment racks, as well as the two-link and at least one four-link, additionally inserted into the section, are pivotally connected to the table and the base of the section, while the four-link and two-link are placed in the form of a pantograph, and their swivel connections to the table and the base of the section are each with two fulcrum.

The above essential features of the proposed technical solution, different from the closest analogue, are necessary and sufficient in all cases to which the scope of legal protection of the utility model applies.

It is also proposed:

- connect the table and the base of the section to each other with two racks of table adjustment.

- Place the two-link and four-link between the table adjustment racks.

- rotate the support with a swivel unit for adjusting the angle of inclination relative to the horizontal plane of the table.

- to perform the four link in the form of a Chebyshev mechanism.

- perform a tray in the table, and place a swivel support in it.

Brief Description of the Drawings

The essence of the proposed technical solution is illustrated by drawings:

- where in FIG. 1 shows a section of a support lining in operation with a raised conveyor drive head.

- where in FIG. 2 shows the section of the support lining in the operating mode with the raised drive head of the conveyor without using a patch.

- where in FIG. 3 shows the section of the support lugs in the initial position.

- where in FIG. 4 shows a cross section AA of the interface section.

- where in FIG. 5 shows the reference points of the hinge joints of the table and the base of the section interacting with the additional section of the support lining.

Industrial applicability

The operation of the claimed technical solution is shown by the example of a support lining in which one of the sections is held in a vertical position by a movable coupling of the upper units using a rope (not shown in the drawing), mounted on one of the upper sections.

The interface support section contains: base 1, upper 2, racks 3, table 4, swivel support 5 with a swivel adjustment unit 5.1, two adjustment racks 6 of table 4, hinged mounting 6.1 racks

adjustments 6 to the base 1 and hinge 6.2 adjustment racks 6 to the table 4, four-link 7, hinge 7.1 four-link 7 to the base 1 and hinge 7.2 four-link 7 to the table 4, two-link 8, hinge 8.1 two-link 8 to the base 1, hinge fastening 8.2 double link 8 to the table 4.

The auxiliary section of the support lining contains: base 9, upper 10, rack 11.

After mounting the lining in the drift, the drive head of the conveyor 12 is placed and fixed on the rotary support 5 of the table 4.

Acting on the adjustment racks 6 of table 4, the required height of the drive head 12 relative to the soil level in the lava is selected, while the four-link 7 and two-link 8 interacting in the form of a pantograph prevent the lateral displacement of the table 4 due to the load of the conveyor head 12 on the hinge 6.1 and 6.2 of the adjustment racks 6 of the table 4, and also provide a rectilinear movement of the table 4 relative to the vertical axis of the main section.

The presence in each element of the four-link 7 and two-link 8 two support points of the hinges 7.1 and 7.2, as well as two support points of the hinges 8.1 and 8.2, - ensures the stability of the drive of the conveyor head 12 when the table 4 is exposed to external forces created under load of the drive head of the conveyor 12. When this execution of the four-link 7 and two-link 8 is possible in the form of frame structures.

Also, the option of placing the rotary support 5 in the tray 13 of the table 4 allows you to optimally adjust the landing depth of the drive head of the conveyor.

After the work cycle is completed in the working face, the section with the top 2 is unloaded, then the section is moved by the size of the excavation step by means of a shunting winch (not shown in the drawing). As a result, the movement is carried out and the section is unloaded from the working efforts and weight. After the completion of the movement, the section bursts. The movement of the auxiliary section with the upper 10 and the base 9 is carried out similarly.
