Description

Technical Field

[0001] This utility model relates to the technical field of pipeline construction measurement tools, specifically a buried pipeline excavation inspection and burial depth measuring ruler. Background Technology

[0002] Pipeline burial depth refers to the vertical distance from the ground surface to the bottom of the pipeline. For example, to protect buried pipelines from damage by ground facilities and vehicles, the soil cover on top of the pipeline is generally not less than 0.7m, and not less than 1.2m when crossing rivers or railways.

[0003] During the excavation of buried pipelines, in order to determine the excavation depth, it is necessary to measure in real time. The traditional measurement method is to use a tape measure. However, the tape measure is prone to bending under stress when measuring depth, which not only makes the measurement inconvenient but also easily leads to measurement errors. Based on this, a buried pipeline excavation depth measuring ruler is provided. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-5 In this embodiment of the utility model, a buried pipeline excavation inspection burial depth measuring ruler includes a measuring ruler assembly 1 consisting of a vertical ruler 101 and a horizontal ruler 102. The vertical ruler 101 and the horizontal ruler 102 are relatively rotatably connected by a connecting assembly 2, and the vertical ruler 101 and the horizontal ruler 102 can achieve relative displacement.

[0034] The connecting component 2 includes a first sliding lock 201a, a second sliding lock 201b, a rotation unit, and a locking and limiting unit;

[0035] The first sliding lock 201a and the second sliding lock 201b are slidably connected to the vertical ruler 101 and the horizontal ruler 102, respectively, to realize the relative displacement operation of the vertical ruler 101 and the horizontal ruler 102. The rotating unit is used to realize the rotating connection between the first sliding lock 201a and the second sliding lock 201b, thereby realizing the relative rotation adjustment of the vertical ruler 101 and the horizontal ruler 102. The locking and limiting unit is used to limit and fix the rotation angle of the rotating unit.

[0036] Both the first sliding lock 201a and the second sliding lock 201b are composed of an I-shaped slider 2011, an arc-shaped spring buckle 2012, and a fixing plate 2013.

[0037] Four curved spring clips 2012 are provided, and they are arranged in pairs. The two sets of curved spring clips 2012 are symmetrically fixed on both sides of the middle part of the I-shaped slider 2011. The two curved spring clips 2012 in each set are symmetrically distributed with respect to the center line of the I-shaped slider 2011. The fixing plate 2013 is symmetrically fixed to the upper and lower ends of one end face of the I-shaped slider 2011.

[0038] The vertical ruler 101 and the horizontal ruler 102 are both provided with sliding tooth grooves 103 in the middle;

[0039] The I-shaped slider 2011 of the first sliding lock 201a is slidably connected to the inner side of the sliding tooth groove 103 on the vertical ruler 101, and the I-shaped slider 2011 of the second sliding lock 201b is slidably connected to the inner side of the sliding tooth groove 103 on the horizontal ruler 102, and the arc-shaped snap 2012 is engaged in the tooth grooves on both sides of the sliding tooth groove 103.

[0040] The end faces of the vertical ruler 101 and the horizontal ruler 102 are in contact with each other. The fixing plate 2013 of the first sliding lock 201a and the fixing plate 2013 of the second sliding lock 201b are respectively replaced by the end faces of the vertical ruler 101 and the horizontal ruler 102 that are far apart from each other, so as to realize the contact limit of the vertical ruler 101 and the horizontal ruler 102.

[0041] The rotating unit includes a rotating hole 202 and an I-shaped cylinder 204;

[0042] A rotating hole 202 is formed in the middle of the I-shaped slider 2011 of the first sliding lock 201a and passes through both ends of the I-shaped slider 2011. An I-shaped cylinder 204 is fixed to one end of the middle of the I-shaped slider 2011 of the second sliding lock 201b and is rotatably connected to the rotating hole 202, so as to realize the rotatable connection between the first sliding lock 201a and the second sliding lock 201b.

[0043] The locking and limiting unit includes a screw hole 206 and a bolt 207;

[0044] The screw hole 206 is opened in the middle of the I-shaped cylinder 204 and completely penetrates the I-shaped cylinder 204 and the I-shaped slider 2011 of the second sliding lock 201b. The bolt 207 thread passes through the rotating hole 202 and is threadedly connected to the screw hole 206. The knob part of the bolt 207 is tightly fitted to the end face of the fixing plate 2013 of the first sliding lock 201a, which is used to realize the relative fixation of the first sliding lock 201a and the second sliding lock 201b.

[0045] In this embodiment: it should be noted that: in the normal storage state, the horizontal ruler 102 and the vertical ruler 101 are parallel to each other, so that the whole is in a straight line, which is convenient for storage;

[0046] When it is necessary to measure the excavation depth of buried pipelines, the operating steps are as follows:

[0047] First, loosen bolt 207 to release the pressure on the first sliding lock 201a. At this time, the first sliding lock 201a and the second sliding lock 201b rotate relative to each other. In this way, the horizontal ruler 102 and the second sliding lock 201b can be rotated as a whole by 90 degrees, so that the horizontal ruler 102 and the vertical ruler 101 are perpendicularly distributed at 90 degrees. Then tighten bolt 207 to keep the angle between the horizontal ruler 102 and the vertical ruler 101 fixed.

[0048] Then, the horizontal ruler 102 can be pulled upward a certain distance relative to the vertical ruler 101. The second sliding lock 201b and the first sliding lock 201a move upward simultaneously. The arc-shaped spring buckle 2012 on the first sliding lock 201a is squeezed and deformed by the protruding teeth on the inner wall of the sliding tooth groove 103 on the vertical ruler 101. When it encounters the tooth groove, it will reset under its own elastic force. This process is repeated. While the horizontal ruler 102 moves upward, it can also be fixed at a specified height (it should be noted that at this time, the height of the horizontal ruler 102 to the bottom of the vertical ruler 101 is controlled to be lower than the depth of the excavated trench).

[0049] Then, based on the distance from the vertical ruler 101 to the side of the trench, pull the horizontal ruler 102 horizontally. At this time, the second sliding lock 201b, the first sliding lock 201a and the vertical ruler 101 remain relatively stationary, and only the horizontal ruler 102 moves. Finally, make the distance from the end of the horizontal ruler 102 to the vertical ruler 101 greater than the distance from the vertical ruler 101 to the side of the trench.

[0050] Finally, lift the entire measuring ruler assembly 1 and move it above the position to be measured (it should be noted that the horizontal ruler 102 is above the ground). Then, slowly lower the measuring ruler assembly 1 and make the bottom of the vertical ruler 101 contact the bottom of the trench. During this process, the end of the horizontal ruler 102 will first contact the ground next to the trench. Then, as the vertical ruler 101 continues to move down, the horizontal ruler 102 is restricted by the ground and cannot move down further. Its second sliding lock 201b and first sliding lock 201a move up relative to the vertical ruler 101. Thus, when the bottom of the vertical ruler 101 contacts the bottom of the trench, the height from the lower surface of the horizontal ruler 102 to the bottom of the vertical ruler 101 is the excavation depth of the trench.

[0051] Next, slightly move the measuring ruler assembly 1 so that the horizontal ruler 102 is not in contact with the ground, and then tilt the measuring ruler assembly 1 to read the scale value of the vertical ruler 101 corresponding to the horizontal ruler 102. This value is the excavation depth of the trench. (It should be noted that the length of the long side of the horizontal ruler 102 is less than the width of the trench but greater than half of the width of the trench, so that the measuring ruler assembly 1 can be tilted and placed in the trench. It should also be noted that the surveyor can also stand on the ground to take measurements, and the measurement operation method is the same as the above operation.)

[0052] Please refer to this carefully. Figures 4-5 The locking and limiting unit also includes a limiting post 203 and a protrusion 205;

[0053] The limiting post 203 is fixed to one end of the I-shaped slider 2011 of the first sliding lock 201a. There are two limiting posts 203, and the two limiting posts 203 are arranged in a ring around the rotating hole 202.

[0054] The protrusion 205 is fixed to the outer side of one end of the I-shaped cylinder 204. The protrusion 205 is located in the middle area of ​​the two limiting posts 203. The two limiting posts 203 are used to limit the rotation angle of the protrusion 205.

[0055] In this embodiment, it should be noted that the two protrusions 205 are distributed at an angle of 90 degrees, which makes the maximum angle between the horizontal ruler 102 and the vertical ruler 101 90 degrees perpendicular, thereby facilitating the convenient unfolding and storage of the horizontal ruler 102.

[0056] Please refer to this carefully. Figures 1-5 The width of the large part of the I-shaped slider 2011 matches the width of the inner wall of the sliding tooth groove 103. The thickness of the large part of the I-shaped slider 2011 matches the thickness of the vertical ruler 101 and the horizontal ruler 102. The thickness of the small part of the I-shaped slider 2011 and the thickness of the arc-shaped spring buckle 2012 are less than the thickness of the vertical ruler 101 and the horizontal ruler 102.

[0057] In this embodiment: the above structure can keep the measuring ruler in a non-loose state, and the structure of the small part of the I-shaped slider 2011 with a thickness less than the thickness of the vertical ruler 101 and the horizontal ruler 102 is used to provide a matching space for the limiting post 203 and the protrusion 205.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
