Description

Technical Field

[0001] The present application belongs to the technical field of measurement auxiliary tools, and specifically relates to a gyro inclinometer support frame. Background Art

[0002] The inspection of large-diameter boreholes is to use a gyro inclinometer to conduct acceptance and testing on the drilled holes after the drilling is completed to obtain the geometric data of the large-diameter boreholes. The obtained geometric data can be used to judge the opening quality of the large-diameter boreholes.

[0003] Among them, the gyro inclinometer used to measure large-diameter boreholes is a stainless steel tube weighing 30 kg, 2 m long and 4 cm in diameter. The gyro inclinometer can accurately measure the geometric shape and geometric dimensions of large-diameter boreholes. The obtained geometric shape and geometric dimensions can reflect the softness and hardness of the rock in the vicinity of the large-diameter borehole, which has important guiding significance for the control of subsequent drilling quality.

[0004] In the prior art, when using a gyro inclinometer to inspect large-diameter boreholes, there are no auxiliary tools. The user has to manually grasp the rope connected to the gyro inclinometer and lower the gyro inclinometer along the wall of the large-diameter borehole. During the lowering process, the gyro inclinometer cannot be placed in the center of the large-diameter borehole, which affects the acquisition of geometric data of the large-diameter borehole. At the same time, during the process of lowering the gyro inclinometer, the rope always contacts and rubs against the hole wall, which poses a risk of the rope breaking and causing the gyro inclinometer to fall off.

[0005] Furthermore, the gyro inclinometer is lifted manually by pulling the rope vertically upward. Due to the gyro inclinometer's weight, the hole's location makes it difficult for multiple people to stand and operate it together, and applying force is difficult. This makes lifting the gyro inclinometer extremely inconvenient, making it extremely difficult to complete the measurement of large-diameter boreholes. Therefore, the invention of a support frame that can easily complete the measurement of large-diameter boreholes is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0006] In order to solve the above technical problems, the present application provides a gyro inclinometer support frame to solve the technical problem that in the prior art, there are no auxiliary tools for detecting large-diameter boreholes, resulting in low accuracy and difficulty in obtaining the obtained large-diameter borehole geometric data.

[0007] The technical solutions adopted to achieve the purpose of this application are:

[0008] A gyro inclinometer support frame comprises a support body and a fixed pulley;

[0009] The bracket body includes a fixing frame, a first support rod and a second support rod; the number of the second support rods is two, the fixed ends of the two second support rods are connected, the angle between the two second support rods is greater than 0° and less than 90°, the two ends of the fixing frame are respectively connected to the two second support rods, and the fixing frame is arranged near the fixed ends of the second support rods;

[0029] In order to enable those skilled in the art to which this application belongs to understand this application more clearly, the technical solution of this application is described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0030] In the embodiments of this application, Figure 1 and Figure 2 As shown, the gyro inclinometer support frame includes a support body 1 and a fixed pulley 2; wherein,

[0031] The bracket body 1 includes a fixing frame 13, a first support rod 11, and a second support rod 12; there are two second support rods 12, the fixed ends of the two second support rods 12 are connected, and the angle between the two second support rods 12 is greater than 0° and less than 90°. In this embodiment, the angle between the two second support rods 12 is 30°; the two ends of the fixing frame 13 are respectively connected to the two second support rods 12, and the fixing frame 13 is arranged near the fixed ends of the second support rods 12;

[0032] The fixed pulley 2 includes a roller 21 and a roller 22; the roller 21 is rotatably mounted on the roller 22, one end of the roller 22 is fixedly connected to the fixing frame 13, and the other end of the roller 22 is fixedly connected to the fixed end of the first support rod 11, while ensuring that the axis of the roller 22 is parallel to the horizontal plane;

[0033] There is an angle between the length direction of the first support rod 11 and the plane where the two second support rods 12 are located, so that the first support rod 11 can support the fixed pulley 2 together with the two second support rods 12, and the fixed end of the first support rod 11 does not extend to the fixed end of the second support rod 12, so that the upper edge of the roller 21 is located outside the bracket body 1, which is convenient for hanging the wire rope. Figure 2 .

[0034] When using the gyro inclinometer support frame to measure the large-diameter borehole, the staff can first adjust the position of the support body 1 so that the central axis of the support body 1 is close to the middle of the large-diameter borehole;

[0035] Then, the staff can hang the wire rope connected to the gyro inclinometer on the roller 21 so that the gyro inclinometer can naturally hang down in the large diameter borehole;

[0036] The gyro inclinometer can be raised and lowered by pulling or releasing the wire rope. During the entire measurement process, the wire rope will not come into contact with the hole wall of the large-diameter borehole, thus avoiding the possibility of wire rope breakage due to friction with the hole wall during the measurement process, and more accurate large-diameter borehole geometric data can be obtained;

[0037] In addition, the fixed pulley 2 in the gyro inclinometer support frame can change the pulling direction of the end of the wire rope away from the gyro inclinometer from the original vertical upward pulling to pulling in the horizontal direction, so that the staff can apply force better, making the measurement of large-diameter boreholes more convenient.

[0038] It should be noted that, since the bracket body 1 is a triangular pyramid structure, if the fixed end of the first support rod 11 is directly connected to the fixed end of the second support rod 12, the first support rod 11 will block the upper edge of the roller 21, and the wire rope cannot be installed by hanging. The gyro inclinometer can only be installed by passing it through the gap between the bracket body 1 and the upper edge of the roller 21. However, the space at the top of the bracket body 1 is small, and the gyro inclinometer is a tubular structure, which is extremely inconvenient to insert, resulting in reduced work efficiency and making it extremely inconvenient to store and use the gyro inclinometer.

[0039] In this embodiment, the fixed end of the first support rod 11 is connected to one end of the roller shaft 22, so that the first support rod 11 will not block the upper edge of the roller 21 and can support the roller 21, making it more convenient to store and use.

[0040] Preferably, the angle between the length direction of the first support rod 11 and the plane where the two second support rods 12 are located is 30°.

[0041] In some embodiments, a limiting groove is provided on the circumferential side wall of the roller 21, and the limiting groove extends along the circumferential direction of the roller 21. The wire rope can be clamped in the limiting groove to prevent the wire rope from falling off the roller 21, thereby making the gyro inclinometer support frame more convenient to use.

[0042] In some embodiments, the bracket body 1 further comprises a triangular fixing assembly 14, the three corners of which are respectively connected and fixed to the first support rod 11 and the two second support rods 12, so as to improve the structural stability of the bracket body 1 and prevent the bracket body 1 from collapsing during use. Preferably, the number of the above-mentioned fixing assemblies 14 is multiple, and the multiple groups of fixing assemblies 14 are spaced apart along the height direction of the bracket body 1, see Figure 2 .

[0043] In some embodiments, the supporting ends of the first support rod 11 and the supporting ends of the second support rod 12 are both provided with telescopic rods 15. The telescopic rod 15 provided on the first support rod 11 can slide along the length direction of the first support rod 11, and the telescopic rod 15 provided on the second support rod 12 can slide along the length direction of the second support rod 12. A limit assembly is provided between the telescopic rod 15 and the first support rod 11 and between the telescopic rod 15 and the second support rod 12.

[0044] Before using the gyro inclinometer support frame, the staff can adjust the extension length of the telescopic rod 15 on the supporting end of the first support rod 11 and the supporting end of the second support rod 12 according to the use requirements or terrain conditions, so that the axis of the roller 22 reaches the required height and remains in a horizontal state, so that the bracket body 1 can be firmly placed at the opening of the large-diameter drilled hole. Then, the telescopic rod 15 can be locked using the limit assembly to prevent the telescopic rod 15 from shrinking into the first support rod 11 or the second support rod 12 during use, which may cause the gyro inclinometer support frame to collapse.

[0045] In some embodiments, the first support rod 11 and the second support rod 12 are both tubular structures. The above-mentioned limit assembly includes internal threads provided in the first support rod 11 and the second support rod 12 and external threads provided on the telescopic rod 15. The telescopic rod 15 is provided in the first support rod 11 or the second support rod 12 through the cooperation of the external threads and the internal threads. By twisting the telescopic rod 15, the extension length of the telescopic rod 15 can be adjusted, so that the use of the gyro inclinometer support frame is more convenient.

[0046] In some embodiments, an anti-slip sleeve is provided at one end of the telescopic rod 15 away from the first support rod 11 or the second support rod 12. The anti-slip sleeve can increase the friction between the telescopic rod 15 and the ground, thereby preventing the position of the gyro inclinometer support frame from changing during use.

[0047] In some embodiments, the gyro inclinometer support frame further includes a depth guide wheel 3 for measuring the depth of the gyro inclinometer. Figure 1 , the wire rope passes through the depth guide wheel 3 and the roller 21 in sequence and is connected to the gyro inclinometer;

[0048] When the wire rope is released downward, the depth guide wheel 3 will calculate the length of the released wire rope and convert the length of the released wire rope into the lowering depth of the gyro inclinometer, so that the staff can better understand the position of the gyro inclinometer.

[0049] It should be noted that before measuring the lowering depth of the gyro inclinometer, the connection end of the gyro inclinometer and the wire rope is first moved to the position of the hole opening of the large-diameter borehole. At this time, the value on the depth guide wheel 3 is reset to zero;

[0050] Then, the wire rope is slowly released, and the gyro inclinometer moves downward along the large-diameter borehole under the action of its gravity. The depth guide wheel 3 can calculate the length of the released wire rope and display it externally through a numerical value so that the staff can promptly understand the position of the gyro inclinometer.

[0051] In some embodiments, the gyro inclinometer support frame further includes a manual winch 4 for retracting / releasing the gyro inclinometer, see Figure 1 , the wire rope and the end away from the gyro inclinometer are wound around the manual winch 4;

[0052] By shaking the manual winch 4, the wire rope can be easily retracted / released, that is, the gyro inclinometer can be raised or lowered, thereby making the retraction and measurement of large-diameter boreholes easier and more convenient.

[0053] In some embodiments, the gyro inclinometer support frame further includes a position adjustment device 5 for determining the positional relationship between the support body 1 and the large diameter borehole; wherein,

[0054] The position adjustment device 5 includes a connecting line and a cone, see Figure 1 , one end of the connecting line is connected to the center of the bottom surface of the cone, and the other end of the connecting line is connected to the top of the bracket body 1;

[0055] During the measurement process or in the stowed state, the cone in the position adjustment device 5 is fixed on the first support rod 11 or the second support rod 12 to prevent it from affecting the lowering or lifting of the wire rope;

[0056] When it is necessary to determine the positional relationship between the bracket body 1 and the large-diameter drill hole, the cone can be released. At this time, the cone will naturally droop under the action of gravity. By observing the positional relationship between the cone and the large-diameter drill hole, the positional relationship between the bracket body 1 and the large-diameter drill hole can be determined.

[0057] When it is determined that the central axis of the bracket body 1 is located in the middle of the large-diameter borehole, the wire rope connected to the gyro inclinometer can be hung on the roller 21, and the gyro inclinometer can be located in the middle of the large-diameter borehole to better complete the measurement of the large-diameter borehole.

[0058] Through the above embodiments, the present application has the following beneficial effects or advantages:

[0059] 1) The position of the fixed pulley 2 for hanging the gyro inclinometer in the gyro inclinometer support frame can be changed by moving the support body 1, so that the gyro inclinometer can be adjusted to the middle position of the large-diameter borehole for lowering and lifting, so that the gyro inclinometer can obtain accurate geometric data of the large-diameter borehole. The configuration of the gyro inclinometer support frame can also prevent the steel wire rope connecting the gyro inclinometer from rubbing against the wall of the large-diameter borehole, which may cause the steel wire rope to wear or break. At the same time, the upper edge of the roller 21 is located outside the support body 1, making it easier to hang the steel wire rope, thereby making it easier to measure the large-diameter borehole.

[0060] 2) The fixed pulley 2 in the gyro inclinometer support frame can change the pulling direction of the wire rope, so that the staff can apply force to pull the wire rope, thereby making the measurement of large-diameter boreholes more convenient.

[0061] 3) The gyro inclinometer support frame provided with the manual winch 4 can easily realize the retraction / release of the wire rope, that is, the lifting or lowering of the gyro inclinometer, thereby making the retraction and measurement of large-diameter boreholes easier and more convenient.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.

[0063] Obviously, those skilled in the art may make various changes and modifications to this application without departing from the spirit and scope of this application.
