Abstract

The utility model discloses a central line hanging positioning rod for a coal mine underground tunnel, belonging to the field of underground central line hanging; the technical problem to be solved is to provide a hanging center line positioning rod which has simple structure, convenient hanging and accurate positioning; the technical scheme for solving the technical problem is as follows: the coal mine underground roadway central line hanging positioning rod comprises a rod body, wherein a fluted disc is arranged at the lower part of the rod body, the fluted disc is connected with the rod body, and barbs are uniformly distributed on the outer surface of the rod body; the utility model discloses but wide application hangs the central line field in the pit.

Description

Positioning rod for hanging center line of underground coal mine roadway

Technical Field

The utility model discloses colliery underworkings hangs central line location stick belongs to and hangs central line technical field in the pit.

Background

When a coal mine underground roadway is tunneled, the advancing direction of tunneling must be mastered according to the exploration and design drawings, the center line point is marked in the roadway and hung, the traditional method for hanging the center line is to measure the center line and the waist line point according to the coordinates of the full drilling rig, drilling a hole in a roadway by using an anchor rod machine or a pneumatic drill, driving a timber pile into the drilled hole, determining the position on the lower surface of the timber pile, driving an iron nail at a designated position, then fastening the engineering line on the nail, hanging a heavy hammer below the engineering line, then a laser is used for irradiating on the heavy hammer so as to determine the trend of the roadway, the method needs field operators to further determine the direction of the roadway according to the diameter of the drilled hole, the timber pile is trimmed, so that the timber pile can be driven into a drilled hole, a large amount of time is wasted, and meanwhile, the iron nails are required to be continuously adjusted and positioned, so that the operation is inconvenient, and the improvement of the working efficiency is not facilitated.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes the defects of the prior art, provides a hanging central line positioning rod which has simple structure, convenient hanging and accurate positioning.

In order to solve the technical problem, the utility model discloses a technical scheme be: colliery underworkings hangs central line location stick, including the barred body, the barred body lower part is provided with the fluted disc, and the fluted disc links to each other with the barred body, and the barred body surface equipartition has the barb.

The rod body and the barb are of an integrated structure.

The rod body, the fluted disc and the barb are made of plastics.

The rod body is a cylindrical rod body.

The fluted disc and the rod body are in a T shape.

The diameter of the rod body is smaller than that of the fluted disc.

The rod body is connected with the fluted disc in a threaded manner.

Compared with the prior art, the utility model following beneficial effect has: the barb has been arranged on the barred body surface, and in inserting drilling that can be convenient, stability is good, prevents that the barred body from droing under the effect of gravity, and the barred body lower part sets up the fluted disc, and the engineering line bolt passes the tooth's socket of different positions according to the position of difference on the barred body, finds the position convenience, and it is quick to hang, need not adjust according to calculating.

Drawings

The present invention will be further described with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic structural diagram of the fluted disc of the present invention.

In the figure, 1 is a rod, 2 is a fluted disc, 3 is a barb, 4 is an engineering line, and 5 is a heavy hammer.

Detailed Description

As shown in fig. 1 and 2, the utility model discloses colliery underworkings hangs central line location stick, including barred body 1, barred body 1 lower part is provided with fluted disc 2, and fluted disc 2 links to each other with barred body 1, and 1 surface equipartition of barred body has barb 3, barred body 1, barb 2 formula structure as an organic whole, barred body 1, fluted disc 2, 3 materials of barb are plastics, and barred body 1 is cylindrical barred body, and fluted disc 2 is the T type with barred body 1, and 1 diameter of barred body is less than 2 diameters of fluted disc, and the connected mode between barred body 1 and the fluted disc 2 is threaded connection.

The utility model discloses when using, insert the barred body in drilling, tie the engineering line on the barred body, after confirming the position, with the engineering line card in corresponding tooth's socket, the weight hangs below, need not fix a position the nail alone and look for the position, can be according to the position of the convenient adjustment central line of angle of difference, convenient to use, simple structure, low in manufacturing cost fixes a position the accuracy.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
