Description

Technical Field

[0001] The utility model belongs to the field of tunnel drilling construction, and in particular relates to a device for remotely marking drilling positions in a tunnel. Background Art

[0002] Auxiliary drilling for mining or tunneling projects, drilling for ventilation, drainage, water exploration, gas exploration, freezing, transportation, as well as pipeline installation for construction and communication, blasting, sampling, grouting, etc. during mining or tunneling construction.

[0003] The five major disasters in coal mines are coal dust, gas explosion, fire, water seepage and roof collapse. In order to deal with these disasters, various drilling methods are needed, such as drilling for water release, drilling special tunnels for water release, drilling for pressure reduction, and interception-type gas discharge drilling. However, when drilling is required for underground disaster management, the positions of the holes are measured and marked manually by going up and down escalators. The operation is complicated, time-consuming, labor-intensive, and dangerous. Utility Model Content

[0005] The utility model adopts the following technical solution: a device for remotely marking drilling positions in a tunnel, comprising:

[0006] A hand-held pole, arranged vertically, with its lower end being held by a worker while standing on the ground of the tunnel;

[0007] The marking bearing plate is arranged horizontally, the lower side of which is fixedly connected to the upper end of the hand-held rod, and a marking groove is vertically penetrated along the direction of the marking bearing plate;

[0008] The two marking tubes are cylindrical structures with an open top, located on the upper side of the marking bearing plate, and the bottoms of the two marking tubes are fixedly connected with a vertically arranged first fixing rod, the first fixing rod passes through the marking groove and extends downward, and is threadedly connected with the fixing bolt, thereby fixing the marking tube on the marking bearing plate; the spacing between the two marking tubes is the predetermined spacing between the two drill holes;

[0009] The first adsorption material is filled in the marking tube and is used to absorb the pigment. When the marking tube is pressed against the top of the tunnel, the adsorbed pigment is painted on the top of the tunnel, thereby obtaining the position of the drill hole from a distance.

[0010] Furthermore, the marking tube also includes:

[0011] The center column is vertically arranged and located in the marking tube, with its lower end fixedly connected to the center of the bottom of the marking tube and its upper end extending upward;

[0012] The shielding sheet is horizontally arranged and located on the upper side of the central column, and its lower side is fixedly connected to the upper end of the central column. The cavity in the marking tube and below the shielding sheet is filled with the first adsorption material. The shielding sheet is used to leave a blank space at the top of the tunnel when the first adsorption material is applied to the top of the tunnel, so that a ring-shaped circle with a blank center is obtained when the paint is applied to the top of the tunnel, so that the drill rod can be aligned with the blank space of the ring-shaped circle to start drilling when drilling.

[0013] Furthermore, it also includes:

[0014] The two endpoint marking frames are both frame structures with an open top, located on the upper side of the marking carrier plate, and the bottom of which is fixedly connected with a second vertically arranged fixing rod, the second fixing rod extends downward through the marking slot, and is threadedly connected with the fixing bolt, thereby fixing the endpoint marking frame on the marking carrier plate;

[0015] The second adsorption material is filled in each endpoint marking frame and is used to paint the adsorbed pigment on the top of the alley when the endpoint marking frame is against the top of the alley, so that the marking carrier plate can be rotated 180 degrees after this marking. When marking the drill hole again, the spacing between adjacent drill holes between the two marks is calculated based on the painted point.

[0016] Furthermore, scales are arranged on the mark bearing plate along its direction, and the distance between any end mark frame and its adjacent mark cylinder is equal to half of the distance between the two mark cylinders.

[0017] The beneficial effects of the utility model are:

[0018] The utility model reduces the drilling construction time, avoids workers going up and down ladders to determine the drilling position, reduces the difficulty and intensity of work, and also reduces the danger;

[0019] The utility model can be operated remotely and determine the drilling position of the top of the tunnel, that is, the worker can stand on the ground of the tunnel to determine the drilling position of the top very accurately;

[0020] The utility model can easily determine the distance between the two top drilling holes by indicating the scale on the marking carrier plate and then moving the distance between the two marking cylinders, and can accurately draw the positions of the drilling holes without close measurement;

[0021] The utility model provides two end point marking frames, and after the first marking is completed, the marking carrier plate can be rotated 180 degrees, and the marking point marked by the end point marking frame can be aligned for the second marking, so that the distance between the adjacent drilling positions in the two markings can be ensured to be equal to the distance between the two marking cylinders that have been set, and the drilling positions can be marked for multiple times continuously, thereby improving the work efficiency;

[0022] The utility model can form an annular circle with a blank center by setting a shielding piece, so that the contact position of the drill rod during drilling can be clearer and more accurate, and avoid the contact position of the drill rod being offset from the actual position due to the circle area being too large, thereby causing inaccurate drilling position.

The first fixing rod 15 extends downward through the marking groove and is threadedly connected to the fixing bolt, thereby fixing the marking tube 12 on the marking carrier plate 11; the spacing between the two marking tubes 12 is the predetermined spacing between the two drill holes.

[0031] The first adsorbent material is filled in the marking tube 12. The first adsorbent material is used to absorb the pigment.
