Description

Horizontal arc-shaped groove with guiding function

Technical Field

The utility model relates to a coal mine transportation equipment technical field specifically is a horizontal arc wall with direction function.

Background

Mining scraper conveyor is as coal transportation equipment, and scraper conveyor is formed by connecting a plurality of middle part grooves, and traditional middle part groove structure is that the groove body does not have angle, whole linear type, and scraper conveyor can only rely on the slight angle at the position of connecting between the groove to adjust crooked change in the transportation, and relative crookedness is very limited. At present, the complex many bendings of colliery working face, the material that equipment cut off need be put according to the equidirectional belt feeder through many sets of haulage equipment on, not only makes equipment input cost increase, overall structure complicated like this, moreover through transporting inefficiency many times. Therefore, it becomes critical to develop a center channel with its own curvature.

Disclosure of Invention

An object of the utility model is to provide a horizontal arc wall with direction function satisfies the turn-round requirement of transportation process, reduces the equipment overlap joint, effectively improves exploitation conveying efficiency and practices thrift the cost.

The purpose of the utility model is realized through the following technical scheme:

the arc-shaped groove is of a roll welding integrated structure and comprises a left ledge, a middle plate, a right ledge, a connecting plate and a pin; the left ledge, the middle plate and the right ledge are all arc-shaped with the same angle in the horizontal direction; the left ledge and the right ledge are formed by rolling, a groove body is formed by welding a middle plate, connecting plates are welded on two sides of the end faces of the left ledge and the right ledge, and pins are welded on the connecting plates; a through long arc-shaped clamping groove is formed in the center of the middle plate up and down;

furthermore, the horizontal angle of the arc-shaped groove is matched with that of the working surface, and the horizontal angle of the arc-shaped groove is 0-90 degrees; the left ledge and the right ledge of the arc-shaped groove are used in a matching way;

furthermore, the angle of the arc-shaped clamping groove is the same as that of the middle plate, the width of the arc-shaped clamping groove is 1/8 times the width of the middle plate, and the depth of the arc-shaped clamping groove is 1/4 times the thickness of the middle plate;

furthermore, the arc-shaped clamping grooves on the upper part and the lower part of the middle plate are matched with a guide device boss required by the transportation equipment to form a guide loop;

furthermore, the connecting plates are four, each connecting plate is provided with a bolt connecting hole, and the two pins are respectively welded on the two connecting plates on different surfaces.

The beneficial effects of the utility model are that: the chute is designed into a circular arc structure, so that the single conveying device can turn in a roadway, the coal return caused by the overlapping of the devices is reduced, the types of the devices are simplified, the tunneling efficiency of the roadway is greatly improved, and the purchase cost of the devices is reduced. The chute is simple in structure, convenient to assemble and disassemble, capable of reducing labor intensity of workers and improving safety factors.

The technical solution of the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

Description of the drawings:

FIG. 1 is a schematic top view of the structure of the present invention;

FIG. 2 is a schematic side view of the structure of the present invention;

in the figure: guide devices of 1 left ledge, 2 middle plates, 3 right ledges, 4 connecting plates, 5 pins and 6

The specific implementation mode is as follows:

in the following, the technical solutions in the embodiments of the present invention are described in detail and clearly with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments.

The utility model provides a horizontal arc-shaped groove with guiding function, as shown in figure 1 and figure 2, comprising a left ledge 1, a middle plate 2, a right ledge 3, a connecting plate 4 and a pin 5;

the arc-shaped groove is of a roll welding integrated structure, a left ledge 1 and a right ledge 3 are welded into a groove body through a middle plate 2, the end faces of the left ledge and the right ledge are welded with a connecting plate 4, and a pin 5 is welded on the connecting plate 4;

the left ledge 1 and the right ledge 3 are formed by rolling, the left ledge and the right ledge are characterized in that the left ledge and the right ledge are in arc shapes, a certain angle is formed between the left ledge and the horizontal direction, the mark is α degrees, the optimal scheme is that α degrees are 22.5 degrees, the angle can be adjusted according to the required adaptation of a driving and mining working face, so that the angle is not limited, and the left ledge and the right ledge are used in parallel in a matched mode;

the angle of the middle plate 2 is consistent with the shape of the ledge, a guide groove which is full-length and L-wide is arranged at the horizontal center of the arc, and the depth of the guide groove is A.

The utility model discloses a use method does: install the arc wall in the section that needs to turn, confirm arc wall angle and quantity according to the turn angle, the transportation of turn process utilizes the protruding of 6 on the guider and the direction recess cooperation of arc wall medium plate to realize spacing completion turn.

It should be understood that the above detailed description of the technical solution of the present invention with the help of preferred embodiments is illustrative and not restrictive. After reading the description of the present invention, those skilled in the art may modify the technical solutions described in the embodiments or make equivalent substitutions for some technical features, and these modifications or substitutions do not make the essence of the corresponding technical solutions depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
