Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary devices for comprehensive mining work, and specifically relates to a new type of special-angle iron column shoe for comprehensive mining working face. Background Art

[0002] The fully mechanized mining face is a mining face equipped with comprehensive mechanized equipment underground in a coal mine. When the fully mechanized mining face is affected by the geological structure, the support often collapses. In order to ensure that the support position meets the requirements, it is necessary to use a single column to assist in pulling the support. To ensure the support pulling effect, it is usually necessary to support a single column "obliquely" adjust the support above the conveyor rack. However, since the support of the single column requires a certain angle, and the single column and the rack are both metal iron, there are certain safety hazards during the use of the single column to adjust the support. However, due to the different inclinations of the working face, the iron column has different inclination angles to the side. Therefore, the fixed-angle support device is difficult to support the iron column at a special angle. For this reason, we proposed a new type of special-angle iron column shoe for fully mechanized mining faces. Utility Model Content

[0003] In view of the shortcomings of the existing new special-angle iron column shoes for comprehensive mining working faces, the utility model provides a new special-angle iron column shoe for comprehensive mining working faces, which has the function of adjusting the angle of the first disc inside the triangular holder to adjust the inclination angle of the plate body, and at the same time, the angle of the positioning ring installed on the outside of the plate body can be adjusted. By adjusting the angle of the positioning ring, the positioning ring has the advantage of obliquely supporting the iron column, thereby solving the problems raised in the above-mentioned background technology.

[0004] The utility model provides the following technical solutions: a new type of special-angle iron column shoe for a comprehensive mining working face, comprising a triangular socket, a positioning groove is provided inside the lower end of the triangular socket, a first disc is movably sleeved inside one side of the triangular socket, a support plate is fixedly connected to the outside of the first disc, a second disc is fixedly connected to one side of the support plate, an arc plate is fixedly connected to one end of the support plate, a screw is installed inside the arc plate, a plate body is welded inside the support plate, a slide groove is provided inside the plate body, a splint is movably sleeved inside the slide groove, an adjustment plate is fixedly connected to one end of the splint, a fastening bolt is installed inside one end of the adjustment plate, and a positioning ring is placed outside the plate body.

[0005] Furthermore, two groups of positioning grooves are installed at the lower end of the triangular holder, and the positioning grooves are sleeved on the outside of the conveyor rack.

[0006] Furthermore, the first disc is circular, the triangular holder is triangular, and the plate is mounted on one end of the inclined surface of the triangular holder.

[0007] Furthermore, the second disc is sleeved on the outside of the triangular holder, and a movable angle is provided between the triangular holder and the support plate.

[0008] Furthermore, a slide groove is provided inside the arc-shaped plate, and the screw rod is movably sleeved inside the slide groove.

[0009] Furthermore, the positioning ring is circular and is located in the middle of one end of the plate body.

[0010] Furthermore, the slide grooves are installed at the four corners of the outside of the plate body, the inner side of the clamping plate is arc-shaped, and the clamping plate is fitted on the outside of the positioning ring. Beneficial Effects

[0011] 1. The new type of special-angle iron column shoe for the fully mechanized mining working face has a positioning groove opened at the bottom of the triangular clamp, which is clamped on the rack of the conveyor. At the same time, a plate is installed on the side of the triangular clamp, and the plate drives the positioning ring to support the iron column. Then, when the positioning ring is at a special angle, the positioning ring can support the obliquely extended iron column, thereby improving the stability of the iron column during support.

[0012] 2. The new type of special-angle iron column shoe for the fully mechanized mining working face can be adjusted by adjusting the angle of the first disc inside the triangular holder, that is, the inclination angle of the plate body can be adjusted, and at the same time, the screw rod can be rotated to limit the position of the arc plate outside the triangular holder. That is, after the inclination angle of the plate body is adjusted, the plate body drives the positioning ring to provide auxiliary support for the iron columns extending at different angles.
