DETAILED DESCRIPTION

[0020] 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.

[0021] Example 1

[0022] like Figures 1 to 4 The fracture measuring device for oilfield exploration and development shown includes a fixed frame 1, with four movable wheels 2 installed at the bottom corners of the fixed frame 1. First sliding rods 3 are symmetrically arranged on the inner wall of the fixed frame 1, with positioning blocks 4 sliding on the first sliding rods 3. Second sliding rods 5 are provided on the top of each positioning block 4. A measuring frame 6 is slidably arranged between the second sliding rods 5. A first sliding groove 701 is opened on the rear right side of the inner wall of the measuring frame 6, and a first rack 703 is connected to the first sliding groove 701 via a first slider 702. A second sliding groove 801 is opened on the front left side of the inner wall of the measuring frame 6, and a second rack 803 is connected to the second sliding groove 801 via a second slider 802. Detection points 10 are provided on the bottom inner sides of both the first rack 703 and the second rack 803 via extension plates 9. A fixing plate 11 is connected to the measuring frame 6 between the first rack 703 and the second rack 803. A gear 12 is rotatably mounted on the top of the fixing plate 11, and the gear 12 meshes with both the first rack 703 and the second rack 803. A mounting base 13 is provided on the front side of the bottom of the measuring frame 6. A swing rod 15 is rotatably mounted on the rear side of the top of the mounting base 13 via a driving component 14. A guide rail 17 is mounted on the top of the second rack 803 via a connecting block 16. A guide block 18 is provided at the bottom of the swing rod 15 and is located inside the guide rail 17. An adjustment hole 20 is provided on the front side of the mounting base 13. A limit rod 21 is connected between the tops of the second slide rods 5. A screw 22 is rotatably mounted on the front side of the limit rod 21 and is threadedly connected to the adjustment hole 20. A handle 23 is provided on the top of the screw 22.

[0023] This invention employs two detection points 10, initially coinciding, which can simultaneously move outwards to both ends of the crack. The crack width is directly determined by the distance between the detection points 10, avoiding the problem that a single detection point 10 cannot fully reflect the crack's direction and distribution. This invention also features an automatic centering function. When the initial position of the device is not at the center of the crack, the measuring frame 6 can be automatically moved to the center of the crack by driving the detection points 10, ensuring the accuracy of the detection data. It can also be used in conjunction with subsequent depth data detection. Through the meshing of the gear 12 and rack, and the cooperation of the swing arm 15 and guide rail 17, the two detection points 10 can move outwards at the same speed and with the same stroke, ensuring the synchronization of the measurement process, reducing operational errors, and improving measurement efficiency.

[0024] Example 2

[0025] As Figures 1 to 4 The utility model provides a kind of fracture measuring device for oilfield exploration and development, including fixed frame 1, fixed frame 1 is set to open in front side, can be pushed frame moves by relying on the mobile wheel 2 of four corners installation of its bottom when measuring, when not need to measure then can stand the open area of fixed frame 1 front side and move the whole device, considering that measuring environment is mostly uneven ground, so push can avoid the thing that device is moved unstable and is bumped and damaged when carrying due to unidirectional force.

[0026] First slide rod 3 is symmetrically arranged between the inner wall of fixed frame 1, and positioning block 4 is slidably arranged on first slide rod 3, second slide rod 5 is arranged on the top of positioning block 4, and measuring frame 6 is slidably arranged between second slide rod 5, measuring frame 6 is used to install two detection points 10, and detection points 10 are initially in the same position of coincidence, and are moved outward during detection, until they are respectively located at the two ends of crack, and then the width of crack can be obtained through the distance between detection points 10;Wherein the initial position of the two detection points 10 of coincidence can be used for joint analysis data, such as calculating crack extension direction.

[0027] In addition, positioning block 4 can move synchronously under the connection of second slide rod 5 and measuring frame 6, so that when the device is not initially located at the midpoint of crack, detection points 10 in measuring frame 6 can be first driven to move outward, when a detection point 10 first contacts crack, stop moving, then measuring frame 6 will be forced to move to the crack corresponding to another detection point 10, until another detection point 10 also contacts crack, at this time, measuring frame 6 is located at the center position of crack, and operator can make other detection at this place, such as depth detection, to ensure the accuracy of detection data. Wherein, the movement of measuring frame 6 means that positioning block 4 moves on first slide rod 3, and second slide rod 5 also moves, which does not affect the detection of crack.

[0028] Before testing, the operator needs to position the device above the crack. At this point, the testing point 10 is not yet inserted into the crack. Therefore, the measuring frame 6 needs to be moved downwards until the testing point 10 is inserted into the crack for testing. A mounting base 13 is located on the front bottom of the measuring frame 6. An adjustment hole 20 is provided on the front side of the mounting base 13, and a thread (not shown in the figure) is provided inside the adjustment hole 20. A limit rod 21 is connected between the top of the second slide rod 5. A screw 22 is rotatably mounted on the front side of the limit rod 21, and the screw 22 is rotatably connected to the helical screw inside the adjustment hole 20. It is understood that rotating the screw 22 will cause the mounting base 13 to move up and down under the force generated by the screw 22 and the helical screw inside the adjustment hole 20, thus moving the entire measuring frame 6 up and down, switching the working state of the device. A handle 23 is also provided on the top of the screw 22, allowing the operator to easily rotate the screw 22 to move the measuring frame 6 up and down and switch the working state.

[0029] Example 3

[0030] like Figures 1 to 4 The illustrated fracture measuring device for oilfield exploration and development involves rotating handle 23 to move the measuring frame 6 downwards, positioning the detection point 10 between fractures. This allows the detection point 10 to move further. Given that the two detection points 10 overlap, it is also necessary to ensure that each monitoring point moves outwards at the same speed and for the same distance to guarantee the accuracy of subsequent joint detection data. Specifically:

[0031] A first slide groove 701 is opened on the rear right side of the inner wall of the measuring frame 6. A first rack 703 is connected to the first slide groove 701 through a first slider 702, meaning that the first rack 703 can move to the left within the first slide groove 701. A second slide groove 801 is opened on the front left side of the inner wall of the measuring frame 6. A second rack 803 is connected to the second slide groove 801 through a second slider 802, meaning that the second rack 803 can move to the right within the second slide groove 801. Detection points 10 are set on the bottom inner sides of both the first rack 703 and the second rack 803 through extension plates 9. The detection points 10 are initially set to coincide.

[0032] The fixed plate 11 is connected between the first rack 703 and the second rack 803 in the measuring frame 6, the top of the fixed plate 11 is rotatably provided with a gear 12, the gear 12 is engaged with the first rack 703 and the second rack 803; meanwhile, the rear top of the mounting seat 13 is rotatably provided with a swing rod 15 through a driving piece 14, that is, the driving piece 14 can drive the swing rod 15 to rotate, the top of the second rack 803 adjacent to the swing rod 15 is provided with a guide rail 17 through a connecting block 16, the bottom of the swing rod 15 is provided with a guide block 18, and the guide block 18 is located in the guide rail 17; that is, the driving piece 14 drives the swing rod 15 to rotate, which drives the guide block 18 to move in the guide rail 17, the force generated by the guide block 18 drives the first rack 703 to move right through the guide rail 17 and the connecting block 16, and finally drives the second rack 803 to move left synchronously through the gear 12. That is, the first rack 703 and the second rack 803 are both moved outward to realize synchronous movement of the detection point 10, until they are respectively located at the two ends of the crack, and then the width of the crack can be obtained through the distance between the detection points 10, or the crack extension direction is calculated through joint analysis in the later stage.
