Description
Technical Field
The utility model relates to mapping engineering equipment, in particular to a measuring marker for a downhole wire point.
Technical Field
Measurement markers (surveymarks) are markers that mark the position of a ground measurement control point, and are various markers that the mapping department establishes and maintains on the ground, underground, or on a building after measurement. The conducting wire points are selected series of points (measurement marks are usually arranged on the points) on the ground, the points are connected into folding lines, the lengths and turning angles of the folding line edges are sequentially measured, the line is called a conducting wire, and the points are called conducting wire points. In the field of mapping engineering it is necessary to provide markers on the points of the wires. Such a marker is a wire point measurement marker (hereinafter, for convenience of description, may be simply referred to as a "measurement marker" or a "marker").
Typically, the wire point measurement markers are placed on the ground. The wire point measurement markers located on the ground are typically serviced by a specialist in order to ensure that the marker is present, complete, clear, measurable and forms an effective set of protection methods.
In general, the measurement marker is made of wood or metal, and is easily corroded or decayed by corrosion or oxidation of moisture, humidity, microorganisms, air, or the like. Wooden measurement markers are susceptible to corrosion or decay, resulting in the markers losing their marking and mapping functions. While metallic markers are typically made of iron, they are prone to oxidation or corrosion, making them difficult to identify, or completely unrecognizable.
Disclosure of Invention
Technical problem to be solved by the utility model
When the measurement marker corrodes or decays, it sometimes needs to be replaced. However, the markers tend to spike into the rock, rock mass or rock joints. In the case of an iron marker, the marker is either not removed due to the rock mass being too hard, or is consolidated with the rock mass due to oxidation of the marker, and is difficult to remove. These conditions result in the tag not being removed for replacement, and only being replaced at another location. However, if the marker is additionally provided at another place, this means that a series of complicated mapping works are to be performed again, increasing much of the work.
In addition, when the geographical information or mapping information marked by the marker needs to be updated or changed, the measurement marker needs to be updated. However, the measurement markers are often nailed into the rock, rock mass or rock seam and cannot be removed without professional copolymerization or great force. This also causes a lot of inconveniences in the update work.
Furthermore, in mining projects, wire point measurement markers are typically located downhole. First, the downhole environment is typically under ground water, karst water, underground rivers, etc., and these erosion conditions also result in the wire point measurement markers being susceptible to erosion, or being depleted by corrosion, or being severely corroded and unrecognizable, and not continuing to act as markers. Thus, the frequency with which downhole measurement markers may be replaced may be higher. Secondly, in mine engineering, the operation is difficult in many environments or the environment is complex, if a tool or a machine with high destructiveness is used, the problems of collapse, falling rocks and the like are likely to be caused, the production safety problem is caused, the original marked place is destroyed, and the place cannot be marked any more.
The present utility model has been made in view of the above-mentioned technical problems. The technical problems to be solved by the utility model are as follows: to provide a wire point measuring marker which is easy to replace, corrosion-resistant and easy to set.

Detailed Description
The utility model relates to a downhole wire point measurement marker, which comprises: metal rod and sleeve. The metal rod is provided with a cylindrical rod body and a fastening head arranged at one end of the rod body. The sleeve has a hollow cylindrical portion and a tip portion, one end of the hollow cylindrical portion is open, and the other end of the hollow cylindrical portion is the tip portion and is closed. The inner surface of the hollow cylinder part of the sleeve is provided with threads, the outer surface of the rod body is provided with threads, the threads of the rod body and the rod body can be mutually embedded, and the rod body can be screwed into the sleeve from the opening of the hollow cylinder part of the sleeve through the threads of the rod body and the threads of the inner surface of the sleeve.
In the current measurement markers, the general structure is: one end of the metal rod is provided with a fastening head. When the marker is arranged, a nameplate (with a round hole in the middle) recorded with mapping information and geographic information is penetrated on the metal rod and is blocked on the fastening head, and then the marker is nailed into a rock mass or a rock seam.
However, when the tag or the tag mounted thereon corrodes and needs to be replaced, or the information on the tag needs to be updated or changed, the tag needs to be removed for replacement or update. However, these markers are often nailed into the rock mass and are difficult to remove; or the marker is consolidated with the rock mass due to oxidation corrosion and cannot be taken out. Particularly in the underground environment, if the underground environment is forcibly taken out by using brute force, the surrounding geological environment is more likely to collapse, fall stone and the like caused by the fact that the surrounding geological environment cannot bear the force, the production accident is caused, and the original marked place is lost.
In this regard, the designer of the present utility model redesigned the measurement marker and innovatively proposed a sleeve design. Namely, a sleeve is added outside the metal rod of the original marker. The metal rod can be screwed into the sleeve. The following is a detailed description with reference to fig. 1.
As shown in fig. 1, the measurement marker of the present utility model includes: a metal rod (1) having a cylindrical rod body (12) and a fastening head (11) provided at one end of the rod body (12); and a metal sleeve (2) having a hollow cylindrical portion (21) and a tip portion (22), one end of the hollow cylindrical portion (21) of which has an opening (23), and the other end of the hollow cylindrical portion (21) is a tip (22) and is closed. The inner surface of the hollow cylindrical part (21) of the metal sleeve (2) is provided with threads (24), the outer surface of the rod body (12) is provided with threads (13), the threads of the two can be mutually embedded, and the rod body (12) can be screwed into the sleeve (2) from the opening (23) of the hollow cylindrical part (21) of the sleeve through the threads (13) of the rod body and the threads (24) of the inner surface of the sleeve (2).
The metal sleeve (2) has sufficient strength and hardness. In addition, the metal sleeve (2) has a pointed end, which can be easily nailed into the rock or rock seam.
When the marker is arranged, the metal sleeve (2) can be nailed into a rock mass or a rock seam, so that the metal sleeve (2) is fixed in the rock mass or the rock seam; then, penetrating the metal rod (1) into the nameplate; the metal rod (1) with the nameplate is then screwed into the hollow cylindrical part (21) of the metal sleeve (2) from the opening (23) of the metal sleeve (2). Since the inner surface of the hollow cylindrical part (23) of the metal sleeve (2) is provided with the screw thread (24), the outer surface of the rod body (12) is provided with the screw thread (13), the screw threads of the rod body (12) and the screw thread can be mutually embedded, and the rod body (12) can be screwed into the sleeve (2) from the opening (24) of the hollow cylindrical part (23) of the sleeve through the screw thread (13) of the rod body and the screw thread (24) of the inner surface of the hollow cylindrical part (23) of the sleeve.
Thus, two technical effects can be achieved.
First, because of the existence of the sleeve, the metal rod is isolated from the contact of outside moisture, air and microorganisms to a great extent. In addition, the nameplate also plays a role of an open cover to a certain extent, and further isolates external moisture, air and microorganisms. This makes the metal rod less susceptible to corrosion and oxidation. Particularly in environments where such corrosion conditions are severe downhole, the original state can be maintained even after a considerable time.
Secondly, when the nameplate or the metal rod needs to be replaced after a period of time, the metal rod only needs to be unscrewed from the metal sleeve for replacement. The replacement process does not need any special equipment, even does not need any equipment, and can be replaced only manually, so that the replacement difficulty is greatly reduced. Particularly in the environment of fragile and complex underground geological conditions, the very mild and smooth operation is very beneficial to keeping the geological environment safe and the original wire guide point safe.
In addition, the outer surface of the metal sleeve is preferably provided with threads, stripes or irregularities. When the outer surface of the metal sleeve is also provided with threads, stripes or concave-convex, the contact area between the metal sleeve and the rock mass can be further increased, the friction force is increased, and then the metal sleeve can be firmly fixed in the rock mass or the rock seam, so that the marker is prevented from falling off from the rock mass or the rock seam.
In the present utility model, the diameter of the fastening head is larger than the diameter of the metal sleeve. In this way, the fastening head can be blocked at the opening of the metal sleeve. And a nameplate can be clamped between the fastening head and the metal sleeve.
In the present utility model, the length of the rod body of the metal rod is smaller than or equal to the hollow cylindrical body portion of the sleeve, whereby it is possible to ensure that the rod body is completely screwed into the hollow cylindrical body. Therefore, the fastening head can be blocked at the opening of the metal sleeve, and the nameplate can be ensured to be blocked between the fastening head and the metal sleeve.
In the novel use, a sealing element is arranged between the fastening head and the opening of the hollow cylinder part of the sleeve. As described above, although the tag may function as a "cap" for the opening of the hollow cylinder portion to some extent, it is impossible to completely seal the hollow cylinder portion since the tag is generally made of metal and is a rigid body. Therefore, in order to further seal the cylindrical opening portion, in the present utility model, a seal is provided between the fastening head and the hollow cylindrical portion opening of the sleeve. The seal may be a rubber seal, gasket, seal ring, or the like. Therefore, the opening of the cylinder can be thoroughly sealed, and the opportunity that the rod body part of the metal rod is contacted with external moisture, air and microorganisms is thoroughly isolated. Thus, even if a long time passes, the rod body portion of the metal rod and the inside of the hollow cylindrical portion of the metal sleeve can be kept in the original state, and the metal rod can be smoothly screwed out or in when the metal rod or the nameplate is replaced.
In addition, the other surface of the fastening head, which is opposite to the rod body part, is provided with a centering cross, so that the measuring marker can be conveniently screwed into the sleeve or screwed out of the sleeve by using a screwdriver.
Industrial applicability
The measuring marker is easy to replace, strong in corrosion resistance and easy to set, and has wide application prospect in wire point measuring engineering in the mapping industry.
