Description

Technical Field

[0001] The utility model relates to the technical field of engineering survey, and more specifically to a survey fixing and calibration device. Background Art

[0002] Investigation and research work is conducted on the geological conditions of rocks, strata, structures, minerals, hydrology, landforms, etc. in a certain area. There are mainly pit, trench exploration, drilling, geophysical exploration and other methods. Drilling refers to using a drilling rig to drill holes in the strata to identify and divide the subsurface strata and take samples along the depth of the hole. Drilling is the most widely used exploration method in engineering geological surveys, which can obtain deep geological data; and in current engineering geological surveys, when drilling holes, workers usually use ropes to fix or not fix them, so that the entire drill rod is in a state of shaking left and right during the in-situ test process, affecting the accuracy of the in-situ test data, and thus directly affecting the evaluation of the engineering properties of the soil layer. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a surveying fixed calibration device to solve the problems existing in the above-mentioned background technology.

[0005] Furthermore, a size adjusting valve is provided on the outer side of the movable ring body, and a movable ring fixer is provided on the other side of the movable ring body. The diameter of the movable ring body can be adjusted by the size adjusting valve and the movable ring fixer, so that the size of the movable ring body is adapted to the size of the drill pipe, thereby increasing the application range of the device.

[0006] Furthermore, a bracket screw is provided at the other end of the sliding rod bracket, and a scale mark is provided on the outside of the movable groove. The scale mark facilitates the staff to adjust the distance of the bottom end of the sliding rod bracket, and then the sliding rod bracket is placed inside the movable groove through the bracket screw.

[0007] Furthermore, handles are provided on both sides of the fixed calibration plate, which facilitate workers to carry the fixed calibration plate, thereby increasing the comfort of use for the workers.

[0008] Furthermore, an inlay hole is provided on the other side of the top of the fixed calibration plate, a fixed base is provided on one side of the top of the fixed calibration plate, and a fixing screw is provided on the top of the fixed base. The fixed calibration plate is fixed to the drilling rig steel plate by the fixed base and the fixing screw, so that the device cannot move in the vertical direction during use, thereby preventing the vibration generated during the survey from moving the fixed calibration plate, thereby causing errors in the survey results.

[0020] Reference Figure 1-6 A surveying fixed calibration device, firstly, the lifting handle 3 is installed on both sides of the top of the fixed calibration plate 4, then the base reserved hole 14 is opened in the middle of the fixed calibration plate 4, then the fixed base 2 is installed on both sides of the fixed calibration plate 4, then the fixed screw 1 is screwed into the fixed base 2, then four groups of movable grooves 6 are opened on the top of the fixed calibration plate 4, then the bracket screw 7 is passed through the bottom of the slide rod bracket 8, and the bottom of the slide rod bracket 8 is fixed in the movable groove 6, then the tops of the four groups of slide rod brackets 8 are brought close to each other, and then the movable ring body 11 is installed on the top of the four groups of slide rod brackets 8, and fixed by the movable ring The device 12 fixes the movable ring body 11 and the slide rod bracket 8 together, and then the size adjusting valve 9 is installed on the outside of the movable ring body 11, so that the size adjusting valve 9 can adjust the diameter of the movable ring body 11, and then a top reserved hole 10 is opened inside the movable ring body 11, and then the scale mark 13 is installed on one side of the movable groove 6 at the top of the fixed calibration plate 4, and finally an inlay hole 5 is opened on the other side of the top of the fixed calibration plate 4, and a level 15 is installed on one side of the inlay hole 5; it should be noted that the diameter of the base reserved hole 14 should be slightly larger than the outer diameter of the universal drill rod to avoid friction with the drill rod.

[0021] The working principle of the utility model is as follows: during field work in engineering geological survey, the staff first determines the survey site, and then applies lubricating oil around the fixed calibration plate 4 and the reserved hole 14 of the base to reduce the friction caused by the slight shaking of the drill rod and the surroundings, thereby reducing data errors, and then fixes the inlay hole 5 on the raised steel bar column at the front end of the conventional drilling rig through the lifting handle 3, so that the device will not move in the horizontal direction during use, and fixes the device on the drilling rig steel plate through the fixed base 2 and the fixed screw 1, so that the device cannot move in the vertical direction during use. At this point, the entire device will be fixed on the drilling rig, and then the hydraulic rods carried by the four corners of the drilling rig are used to adjust the entire drilling rig to a horizontal direction according to the level 15. At this time, the drill rod remains in a vertical direction. The accuracy of the level 15 is that when the drilling rod footage is 100m, the drilling rod inclination error is within 2°. At this point, the entire drill rod will be in a vertical direction. At the same time, by adjusting the bracket screw 7 and accurately adjusting the sliding rod bracket 8 according to the scale mark 13 provided in the movable groove 6, the movable ring body 11 is in a horizontal direction. At this time, the data read by the four bracket screws 7 on the scale mark 13 should be equal, and then the bracket screw 7 is fixed; then the drilling rig is started, and the drill rod of the drilling rig passes through the top reserved hole 10 and the base reserved hole 14 in sequence for drilling survey, so that the movable ring body 11 and the base reserved hole 14 limit and fix the drill rod, so that the drill rod remains in the vertical direction, which increases the accuracy of the in-situ test data, thereby directly affecting the evaluation of the engineering properties of the soil layer; at the same time, in the face of drill rods of different sizes, the diameter of the movable ring body 11 can be adjusted through the size adjustment valve 9 to make the movable ring body 11 match the size of the drill rod, thereby increasing the scope of application of the device.
