Technical Field
[0001] The utility model relates to the field of perpendicularity detection devices, and particularly to a portable device for detecting the perpendicularity of spiral drill holes. Background Technique
[0002] In the construction of ground photovoltaic power stations, micropile bored piles are widely used in gravel soil and strong and moderately weathered rock foundations due to their high construction efficiency, strong bearing capacity, and wide application range. The hole-forming quality has an important impact on the pouring of subsequent bored piles and the installation quality of brackets. Therefore, the detection of hole-forming perpendicularity is a key link in daily construction management.
[0003] Traditional hole-forming perpendicularity detection generally uses an inclinometer. On the premise that the perpendicularity of the drill pipe is consistent with the perpendicularity of the drilled hole, the inclination of the drill pipe is measured point by point, and the perpendicularity of the drilled hole is converted by using the average angle full-range method. This method is relatively cumbersome, increasing the labor intensity of personnel, and affecting the drilling progress due to the need for drill pipe cooperation. It is not suitable for the detection of the perpendicularity of spiral drill holes of large-area micropile bored piles. Content of the Utility Model
[0004] The purpose of the utility model is to solve the shortcomings existing in the current detection of the perpendicularity of spiral drill holes of micropile bored piles, and to provide a portable device for detecting the perpendicularity of spiral drill holes, which is convenient for detection, does not affect the drilling progress, and can effectively reduce the labor intensity of operators.

The hole position positioning device is located in the middle and lower part of the main rod, and its outer diameter is adapted to the inner diameter of the drilled hole to be detected. The hole position positioning device is fixed on the surface of the main rod with the main rod as the center. The measuring device is fixed on the top of the main rod. The measuring device is composed of a dial, a plumb bob, and a plumb bob fixing frame. One end of the plumb bob fixing frame is connected to the plumb bob. When the main rod is in a vertical state, the vertex of the plumb bob is opposite to the center of the dial.
[0006] The outer diameter of the hole position positioning device of the utility model is adapted to the inner diameter of the drilled hole to be detected, and the hole position positioning device takes the main rod as the center. Therefore, by detecting the perpendicularity of the main rod, the perpendicularity of the drilled hole can be detected, without the need for drill pipe cooperation, and the drilling speed is not affected. The design of the dial and the plumb bob can facilitate the detection of the perpendicularity of the main rod, that is, as long as the utility model is put into the drilled hole, the detection result can be obtained by looking at the plumb bob. The whole detection process is convenient and the labor intensity of the operator is light.

The sleeve is fixedly sleeved on the surface of the main rod. The two ends of the horizontal rod are respectively connected to the sleeve and the vertical rod, and the vertical rod is parallel to the main rod.
[0008] Further design: The hole position positioning device has at least three horizontal rods and vertical rods. The horizontal rods are evenly distributed on the surface of the sleeve at equal angles. The circumcircle formed by the outer surfaces of the three vertical rods is adapted to the inner diameter of the hole to be detected.
[0009] The two ends of the horizontal rod are respectively connected to the sleeve and the vertical rod, which means that the two ends of the horizontal rod are perpendicularly and fixedly connected to the sleeve and the vertical rod by welding respectively.
[0010] The two ends of the horizontal rod are respectively connected to the sleeve and the vertical rod, which means that the inner end of the horizontal rod is hinged to the sleeve by a pin shaft. A limit block for restricting the horizontal rod from rotating downward is arranged at the bottom of the pin shaft. The inner end of the horizontal rod is semicircular, and the outer end of the horizontal rod is hinged to the vertical rod.
[0011] A depth scale bar is arranged on the surface of the main rod, and the main rod is made of stainless steel material.
[0012] A depth scale bar is arranged on the surface of the vertical rod, and the length of the vertical rod exceeds the drilling depth.
[0013] The hole position positioning device includes a sleeve, a horizontal rod and a roller. The sleeve is fixedly sleeved on the surface of the main rod. The roller is connected to the outer end of the horizontal rod. The inner end of the horizontal rod is hinged to the sleeve by a pin shaft. The inner end of the horizontal rod is semicircular.

[0025] Embodiment 1
[0026] As Figure 1 、 4 、6 shown, and with reference to Figure 2, A device for detecting the verticality of a portable auger hole drilling, including a main rod 1, a hole position positioning device 2, and a measuring device 3. The hole position positioning device 2 is located in the middle and lower part of the main rod 1, and the hole position positioning device 2 is fixed on the surface of the main rod 1 with the main rod as the center. The hole position positioning device 2 includes a sleeve 21, a horizontal rod 22, and a vertical rod 23. The hole position positioning device 2 has at least three horizontal rods 22 and vertical rods 23. In this example, there are three. The horizontal rods 22 are evenly distributed at equal angles (i.e., 120° angle) on the surface of the sleeve. The circumcircle formed by the outer surfaces of the three vertical rods is adapted to the inner diameter of the drilled hole to be detected. Generally, there are 3 - 6, and too many will increase the manufacturing cost. And axially, the hole position positioning device 2 has at least two groups according to the height of the vertical rods, located at both ends respectively, to ensure stability and fit with the drilling. In the figure, there are three groups. The sleeve 21 is fixedly sleeved on the surface of the main rod 1. Both ends of the horizontal rod 22 are respectively connected to the sleeve 21 and the vertical rod 23. In this example, both ends of the horizontal rod are perpendicularly and fixedly connected to the sleeve and the vertical rod by welding respectively. The vertical rod 23 is parallel to the main rod 1, and the height of the vertical rod 23 is between 1 / 3 - 2 / 3 of the drilling depth, preferably in the middle of the drilling. In this way, while ensuring that this device can stably fit with the drilling, the overall weight is also reduced.
[0027] The main rod 1 is made of stainless steel material. A depth scale bar 11 is provided on the surface of the main rod 1, below the dial 31, at the upper part of the main rod. The depth scale bar covers the hole depth range. The hole depth can be detected by a spirit level, so that this device has two detection functions of depth and verticality.
[0028] The measuring device is fixed at the top of the main rod. The measuring device 3 is composed of a dial 31, a plumb bob 32, and a plumb bob fixing frame 33. One end of the plumb bob fixing frame 33 is connected to the plumb bob 32. When the main rod 1 is in a vertical state, the vertex of the plumb bob 32 is opposite to the center of the dial 31. A condensing light bulb 34 is installed at the vertex of the plumb bob 32. The power supply of the condensing light bulb is installed inside the plumb bob 32. A control device 36 is provided at the top of the plumb bob 32. The condensing performance of the condensing light bulb is used to conveniently observe whether the vertex of the plumb bob is opposite to the center of the dial.
[0029] Embodiment 2
[0030] On the basis of the above example, as Figure 2-3As shown in the figure, for convenient storage, the inner end of the horizontal rod 22 is hinged to the sleeve through a pin shaft 26. The inner end of the horizontal rod is semi-circular for easy rotation. The outer end of the horizontal rod is hinged to the vertical rod. A limit block 25 for restricting the downward rotation of the horizontal rod 22 is provided at the bottom of the pin shaft 26. The horizontal rod 22 is a foldable structure. After the device is placed down, the horizontal rod 22 rotates downward around the horizontal rod 22, so that when it is stored, the horizontal rod 22 can only be retracted upward, and the horizontal rod 22 and the main rod 1 are closed to reduce the storage volume. The depth scale bar 11 is made on the surface of the vertical rod 23, and the length of the vertical rod exceeds the drilling depth, so that the depth of the hole can be measured at the edge of the hole. In this way, when the device is placed into the drilling hole, the drilling depth can be conveniently read from the depth scale bar without a spirit level. This device has two detection functions of depth and verticality. The other parts not described are the same as those in Embodiment 1.
[0031] Embodiment 3
[0032] As Figure 5 shown in the figure, the hole position positioning device 2 includes a sleeve 21, a horizontal rod 22 and a roller 27. The horizontal rod 22 is perpendicular to the main rod 1. The sleeve 21 is fixedly sleeved on the surface of the main rod 1. The roller 27 is connected to the horizontal rod 22. One end of the horizontal rod 22 is hinged to the sleeve 21 through a pin shaft 26. A limit block 25 for restricting the downward rotation of the horizontal rod 22 is provided at the bottom of the pin shaft 26. The other end of the horizontal rod 22 is hinged to the vertical rod 23. The same as in Embodiment 2, in order to stably fit with the drilling hole, within the hole depth range, there are at least two groups of hole position positioning devices with different heights, and only the uppermost group is shown in the figure. After the device is assembled, it is necessary to insert the device into the hole. The main rod 1 is made of stainless steel material, and a depth scale bar 11 is provided on the surface of the main rod 1, below the dial 31 at the upper part of the main rod.
[0033] The horizontal rod 22 is a telescopic rod with adjustable length. As Figure 5 shown, when in use, first adjust the outermost dimension of each horizontal rod to the radius of the drilling hole and fix it. The other parts not described are the same as those in Embodiment 2.
