In addition, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0032] In addition, the term "same" and the like do not mean that the components must be absolutely the same, but there can be slight differences. The term "vertical" only means that the positional relationship between the components is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly inclined.

[0033] Please refer to Figures 1-3 The present application provides a technical solution: a water engineering and geological fracture measuring device, comprising a movable frame 1, a fixed frame 2 fixed to the movable frame 1, and a scale rod 3 transversely arranged and connected to the lower end of the fixed frame 2, the other end of the scale rod 3 is provided with a length scale; further comprising two fixed rods 4, two measuring rods 5, two base plates 6 and a transverse linear drive assembly 7 connected to the driving end of the two fixed rods 4, the two fixed rods 4 are vertically arranged and the upper ends are slidingly connected to the other end of the scale rod 3, the upper ends of the two measuring rods 5 are respectively vertically slidingly connected to the lower ends of the two fixed rods 4, the two base plates 6 are parallel to the scale rod 3, and the opposite ends are respectively fixedly connected to the opposite sides of the two measuring rods 5, the transverse linear drive assembly 7 is used to drive the two fixed rods 4 to move simultaneously towards or away from each other.

[0034] In the measurement, the whole measuring device reaches one side of the crack to be measured by moving the movable frame 1, the scale rod 3 is initially horizontally placed above the crack, then the two fixed rods 4 are driven to slide along the length direction of the scale rod 3 by the transverse linear driving assembly 7, at the same time, the two fixed rods 4 are driven to move away from or towards each other by the transverse linear driving assembly 7 until the other ends of the two base plates 6 are located above the two sides of the crack to be measured respectively, then the two measuring rods 5 are simultaneously slid downwards relative to the two fixed rods 4 until the two base plates 6 abut against the two sides of the crack to be measured respectively, then the two fixed rods 4 are driven to slide away from each other along the length direction of the scale rod 3 by the transverse linear driving assembly 7 until the lower ends of the two measuring rods 5 abut against the inner walls of the two sides of the crack (in this process, when the lower end of one of the two measuring rods 5 abuts against one side of the crack first, the corresponding fixed rod 4 of the other measuring rod 5 slides relative to the scale rod 3 under the reaction force until the lower ends of the two measuring rods 5 abut against the inner walls of the two sides of the crack), at this time, the width value of the crack can be read from the scale on the scale rod 3. By this measurement method, the measurer only needs to be on one side of the crack and does not need to cross the two sides, which is relatively safe, and the measurer does not need to hold the scale rod 3 to measure, which reduces the problem of inaccurate measurement caused by the inclination of the scale rod 3 when the measurer holds the scale rod 3 to measure, improves the existing technology of manually measuring the crack width, and solves the technical problem of danger in the existing technology; and by this measurement method, whether the crack to be measured has the same height on the two sides or has different heights on the two sides, the two measuring rods 5 can be directly adjusted in the falling height by abutting the two base plates 6 against the ground, so as to ensure the level of the scale rod 3 and solve the problem of inaccurate measurement caused by the inclination of the scale rod 3 in the existing technology.

[0035] By the above measurement method, in the measurement process, the two base plates 6 abut against the ground on the two sides of the crack to be measured respectively, which limits the downward sliding of the measuring rods 5, ensures the adaptive sliding of the measuring rods 5, and makes the assembly of the measuring rods 5 and the fixed rods 4 extend or shorten to the appropriate length, and at the same time, the level of the scale rod 3 can be judged by the abutment angle state of the base plates 6 and the ground.

[0036] In this embodiment, the movable frame 1 includes a frame 11, a plurality of wheels 12 fixedly installed on the frame 11, and a stand 13 fixedly connected to the lower end of the frame 11. The fixed frame 2 is fixed to the stand 13 of the movable frame 1, and the scale rod 3 is horizontally arranged in the direction perpendicular to the stand 13.

[0037] When the whole measuring device is moved, the frame 11 is pushed or pulled to achieve the movement.

[0038] Wherein, the wheel 12 can adopt universal wheel, when moving to position and carrying out measuring operation, the wheel 12 is braked, and the stability of the measuring device during measuring is ensured.

[0039] On the basis of the above embodiment, the counterweight 14 is installed on the frame 11, and the counterweight 14 and the scale rod 3 are separately arranged on both sides of the stand 13, so as to ensure the stability of the frame 11.

[0040] On the basis of the above embodiment, the vertical clamping groove 41 is arranged on one side of the fixed rod 4, the cross section of the vertical clamping groove 41 is in the shape of ladder, and the vertical clamping groove 41 penetrates downwardly to the lower side of the fixed rod 4. The side wall of the measuring rod 5 is fixed with the vertical clamping block 51 which is adapted to be vertically and slidingly connected to the vertical clamping groove 41. The sliding connection between the measuring rod 5 and the fixed rod 4 is realized by clamping the vertical clamping block 51 to the vertical clamping groove 41.

[0041] The limiting groove 42 is arranged at the bottom of the vertical clamping groove 41, and the upper end of the vertical clamping block 51 is fixed with the limiting block 52 which is adapted to be slidingly connected to the limiting groove 42. When the vertical clamping block 51 is vertically and slidingly connected to the vertical clamping groove 41, the limiting block 52 is synchronously sliding in the limiting groove 42, and when the limiting block 52 abuts against the bottom of the limiting groove 42, the measuring rod 5 stops sliding relative to the fixed rod 4, so that the measuring rod 5 is prevented from being separated from the fixed rod 4 by the limiting of the vertical clamping groove 41 and the limiting groove 42.

[0042] Please refer to Figures 1-2 In the embodiment, the fixed frame 2 comprises the fixed plate 21 fixedly connected to the upper end of the movable frame 1, the support rod 22 fixedly connected to the other end of the fixed plate 21, and the vertical linear driving member 23 installed in the middle end of the fixed plate 21, the lower end of the support rod 22 is rotationally connected to the middle end of the scale rod 3, and the driving end of the vertical linear driving member 23 is vertically telescopic, and the driving end is rotationally and slidingly connected to one end of the scale rod 3 along the length direction of the scale rod 3.

[0043] The two-point limiting of the scale rod 3 is formed by the connection of the support rod 22 and the vertical linear drive 23 with the scale rod 3, so as to ensure the balance of the scale rod 3, and the rotation connection point of the support rod 22 with the scale rod 3 is used as a fulcrum, and the extension and retraction of the driving end of the vertical linear drive 23 is used to make the scale rod 3 rotate in the vertical plane with the rotation connection point of the support rod 22 as the midpoint, so as to ensure the horizontal state of the scale rod 3; specifically, when the parking place of the mobile vehicle frame 1 located beside the crack to be measured is a flat ground, the two connection points of the support rod 22 and the vertical linear drive 23 with the scale rod 3 are at the same height, at this time, the scale rod 3 is in a horizontal state, and the two fixed rods 4 can be directly driven to move by the horizontal linear drive assembly 7, and subsequent crack width measurement operation can be performed; when the parking place of the mobile vehicle frame 1 located beside the crack to be measured is an inclined ground, the mobile vehicle frame 1 parked beside the crack to be measured is in an inclined state, so that the initial state of the scale rod 3 is an inclined state, at this time, the vertical linear drive 23 can be started, and the scale rod 3 is driven to rotate in the vertical plane with the rotation connection point of the support rod 22 as the midpoint by the vertical linear drive 23 until the scale rod 3 is horizontal, and subsequent measurement operation can be performed; by this measurement method, the device can perform measurement operation on the inclined ground where the crack is measured, and the horizontal state of the scale rod 3 during the measurement process can be ensured, so as to further solve the problem that the scale rod 3 may be inclined during measurement in the prior art, which leads to uncertain measurement, and to further improve the technical problem of low accuracy in measuring complex cracks in the prior art.

[0044] In the embodiment, one end of the fixed plate 21 is fixedly connected to the upper end of the stand 13 of the mobile vehicle frame 1.

[0045] The vertical linear drive 23 is arranged between the support rod 22 and the stand 13, which can be an electric cylinder or a pneumatic cylinder, the cylinder body is fixedly connected to the fixed plate 21, and the driving end thereof is vertically telescopic.

[0046] Please refer to Figures 4-6 In the embodiment, a stepped hole 31 is formed in the middle end side wall of the scale rod 3, the scale rod 3 is rotationally connected to a center shaft 221 having one end adapted and rotationally connected to the stepped hole 31, and the other end of the center shaft 221 is fixedly connected to the lower end of the support rod 22.

[0047] The connection of the center shaft 221 makes the support rod 22 suspend and install the scale rod 3, and when the angle of the scale rod 3 is adjusted by the driving of the vertical linear drive 23, the scale rod 3 rotates in the vertical plane with the center shaft 221 as the center, and when the driving end of the vertical linear drive 23 stops telescoping, the scale rod 3 remains stationary and balanced under the connection of the center shaft 221.

[0048] The center shaft 221 is perpendicular to the scale rod 3 and the support rod 22.

[0049] As one of the parallel schemes of the embodiment, one end of the center shaft 221 is adapted and rotationally connected to the stepped hole 31, and the other end is rotationally connected to the lower end of the support rod 22.

[0050] As the second parallel scheme of the embodiment, one end of the center shaft 221 is fixedly connected to the middle end of the scale rod 3, and the other end is rotationally connected to the lower end of the support rod 22.

[0051] In the embodiment, one end of the scale rod 3 is provided with a transverse clamping groove 32 extending along the length direction thereof, and the scale rod 3 is slidingly connected with a force applying rod 231 adapted and slidingly connected to the transverse clamping groove 32, and the other end of the force applying rod 231 is rotationally connected to the driving end of the vertical linear driving member 23.

[0052] When the scale rod 3 is adjusted to return to the horizontal state by the extension and retraction of the driving end of the vertical linear driving member 23, the force applying rod 231 rotates relative to the driving end of the vertical linear driving member 23, and at the same time, the force applying rod 231 slides along the transverse clamping groove 32 relative to the scale rod 3.

[0053] The transverse clamping groove 32 has a stepped or dovetail shape in cross section.

[0054] As one of the parallel schemes of the embodiment, the transverse clamping groove 32 is a stepped groove. One end of the force applying rod 231 is stepped and has a circular cross section, and is rotationally connected to the transverse clamping groove 32. In this way, the force applying rod 231 can rotate relative to the scale rod 3 during the adjustment of the inclination angle of the scale rod 3. In the embodiment, the other end of the force applying rod 231 is rotationally or fixedly connected to the driving end of the vertical linear driving member 23.

[0055] Please refer to Figures 1-3 In the embodiment, the scale rod 3 has a circular cross section, and the upper ends of the two fixed rods 4 are simultaneously slidingly and rotationally connected to the other end of the scale rod 3.

[0056] During the measurement, when the whole measurement device reaches one side of the crack to be measured by the movement of the movable frame 1 and the scale rod 3 is initially horizontally placed directly above the crack, the two fixed rods 4 can be simultaneously rotated around the scale rod 3 by applying force to the transverse linear drive assembly 7, until the two fixed rods 4 are in an upwardly inclined state, or even rotated by 180°, so that the measurement rod 5 is on the upper side relative to the corresponding fixed rod 4. At this time, the measurement rod 5 can be prevented from contacting the ground due to natural downward sliding, thereby ensuring that the scale rod 3 is suspended and smoothly moved directly above the crack to be measured. Then, the two fixed rods 4 are simultaneously moved away from or towards each other by the transverse linear drive assembly 7, until the other ends of the two base plates 6 are located directly above the two sides of the crack to be measured, respectively. Thereafter, the two fixed rods 4 are simultaneously reversely rotated around the scale rod 3 by applying force to the transverse linear drive assembly 7, and then the two measurement rods 5 are in a vertical state and simultaneously slide downward relative to the two corresponding fixed rods 4, until the two base plates 6 abut the two sides of the crack to be measured, respectively. Then, subsequent measurement operations can be performed. Through the above measurement method, when the parking place of the movable frame 1 is an inclined plane inclined along the extension direction of the crack, the fixed rod 4 can naturally rotate relative to the scale rod 3 under the action of gravity, to ensure that the downwardly sliding measurement rod 5 accurately slides vertically downward and measures the measurement point, without deviating to measure other measurement points due to the inclination of the measurement rod 5, and without the problem of inaccurate measurement (not only the measurement point is inaccurate, but also the actual measurement data can be inaccurate due to the different inclined state of the ground at the actual measurement point, so that the scale rod 3 in a horizontal state is inclined relative to the actual measurement point at this time).

[0057] Among them, the scale rod 3 is circumferentially provided with a plurality of length scales, so that the distance between the two fixed rods 4 can be intuitively connected by the length scales when the fixed rod 4 is rotated at any angle relative to the scale rod 3.

[0058] Please refer to Figures 1-6 In the embodiment, the transverse linear drive assembly 7 includes two fixed blocks 71 fixedly connected to the two fixed rods 4, a bidirectional screw rod 72 parallel to the scale rod 3, and a rotating rod 73 coaxially inserted into the bidirectional screw rod 72 near one end of the movable frame 1. The two ends of the bidirectional screw rod 72 have opposite screw threads and are threadedly connected to the two fixed blocks 71, respectively.

[0059] When the two fixed rods 4 are simultaneously moved away from or towards each other by the transverse linear driving assembly 7, a torque is applied to the other end of the rotating rod 73 to make the bidirectional screw rod 72 rotate, and the two fixed rods 4 can be simultaneously moved away from or towards each other relative to the fixed scale rod 3 under the limiting action of the scale rod 3 which remains stationary; in this process, the two fixed rods 4 can be simultaneously moved in the same direction relative to the scale rod 3 by applying a pushing force or a pulling force to the other end of the rotating rod 73, until the other ends of the two base plates 6 are located above the two sides of the crack to be measured respectively, so as to achieve the effect of rapid adjustment; when the force applied to the rotating rod 73 is stopped, the two fixed rods 4 remain a constant distance apart under the connection of the bidirectional screw rod 72.

[0060] The other end of the rotating rod 73 extends in the direction of the movable frame 1 so as to be operated by the measurer.

[0061] The fixed block 71 is fixedly connected to the side of the fixed rod 4 away from the vertical clamping groove 41.

[0062] A polygonal hole is formed in one end of the bidirectional screw rod 72, and one end of the rotating rod 73 is adapted and inserted into the polygonal hole.

[0063] In this embodiment, the transverse linear driving assembly 7 further comprises a positioning wheel 74 fixedly connected to the movable frame 1, a positioning block 75 slidably connected to the edge end of the positioning wheel 74, and a positioning rod 76 inserted into the positioning wheel 74, the central axis of the positioning wheel 74 coincides with the central axis of the scale rod 3, the sliding track of the positioning block 75 is circular, the center of the circle coincides with the central axis of the scale rod 3, the positioning rod 76 is simultaneously inserted into the positioning block 75, and the other end of the rotating rod 73 is rotatably and slidably connected to the other end of the positioning block 75.

[0064] In the process of pushing the movable frame 1 to move the entire measuring device, and in the process of moving the entire measuring device to one side of the crack to be measured by the movable frame 1 and preliminarily placing the scale rod 3 above the crack, the two fixed rods 4 can be simultaneously rotated about the scale rod 3 as the central axis by applying a force to the other end of the rotating rod 73, until the two fixed rods 4 are in an upwardly inclined state, or even rotated by 180°, so that the measuring rod 5 is on the upper side relative to the corresponding fixed rod 4, at this time, the measuring rod 5 can be prevented from contacting the ground due to natural downward sliding; in the process of simultaneously rotating the two fixed rods 4 about the scale rod 3 as the central axis, the positioning rod 76 is first extracted from the positioning block 75, so that the positioning block 75 is rotated relative to the positioning wheel 74, and after being rotated to the position, the positioning rod 76 is simultaneously inserted into the positioning wheel 74 and the positioning block 75, which can ensure the height of the rotating rod 73, and further ensure that the two fixed rods 4 are always in an upwardly inclined state, facilitating the movement of the entire measuring device.

[0065] Of course, when the measurement is completed, the two fixed rods 4 can be in an upwardly inclined state by applying force to the other end of the rotating rod 73, so that the measuring rod 5 is rotated around the scale rod 3 as the center axis and directly exits the crack.

[0066] The positioning wheel 74 is fixedly connected to the stand 13 of the movable frame 1.

[0067] The other end of the positioning block 75 is provided with a circular hole, and the rotating rod 73 is a circular rod to achieve rotation and sliding connection with the positioning block 75.

[0068] The edge end of the positioning wheel 74 is provided with a ring groove 741, the center axis of the ring groove 741 coincides with the center axis of the scale rod 3, the cross section of the ring groove 741 is in a stepped or dovetail shape, and one end of the positioning block 75 is adapted and slidingly connected to the ring groove 741 to achieve rotation connection of the positioning block 75 and the positioning wheel 74.

[0069] The edge end of the positioning wheel 74 is also provided with a plurality of insertion holes 742, which are circularly and spacedly distributed around the axis of the positioning wheel 74. And a positioning hole 751 is provided at one end of the positioning block 75, which can be communicated with any insertion hole 742 by rotating the positioning block 75. The positioning rod 76 is adapted to the insertion hole 742 and the positioning hole 751.

[0070] During the rotation of the two fixed rods 4 around the scale rod 3 as the center axis, the positioning rod 76 is first pulled out of the positioning block 75, so that the positioning block 75 is rotated in place relative to the positioning wheel 74, and then the positioning rod 76 is inserted into the insertion hole 742 and the positioning hole 751 at the same time to ensure that the two fixed rods 4 are always in an upwardly inclined state, facilitating the movement of the entire measuring device.

[0071] Please refer to Figures 4-7 In the embodiment, the middle end of the bidirectional screw rod 72 is rotationally connected with a depth measuring assembly 8, the depth measuring assembly 8 includes a sleeve 81 rotationally connected to the middle end of the bidirectional screw rod 72, a winding wheel 82 installed on the sleeve 81, a depth measuring rope 83 with one end fixedly connected to the winding wheel 82, and a weight 84 fixedly connected to the other end of the depth measuring rope 83, and the depth measuring rope 83 has a length scale.

[0072] When the lower ends of the two measuring rods 5 simultaneously abut against the inner walls of the two sides of the crack to read the width value of the crack through the scale on the scale rod 3, the weight 84 can be lowered through the winding wheel 82, and the depth value of the crack can be read through the depth measuring rope 83 when the weight 84 touches the bottom, thereby synchronously completing the depth measurement operation.

[0073] In the process of measuring the width, the lower ends of the two measuring rods 5 abut against the inner walls on both sides of the crack at the same time, and the weight 84 is always in the middle position of the two fixed rods 4, so that the weight 84 is ensured to fall from the middle position of the crack, and the problem that the weight 84 touches the inner wall of the crack during the falling process and affects the accuracy of the crack depth measurement can be reduced.

[0074] In the process of adjusting the position of the fixed rod 4 to make the measuring rod 5 reach the specified position and measuring the width of the crack, the sleeve 81 is always adaptively rotated relative to the bidirectional screw rod 72 under the gravity of the weight 84, so that the weight 84 is always below, and the weight 84 is always in the middle position of the two fixed rods 4.

[0075] In the sleeve 81, a motor 811 is fixedly connected, and the output shaft of the motor 811 is coaxially fixedly connected to one end of the winding wheel 82, so that the winding wheel 82 is driven to rotate by the motor 811, and the unwinding and winding operation of the depth measuring rope 83 is realized.

[0076] In the embodiment, the depth measuring assembly 8 further comprises a camera 85 installed on the sleeve 81, and the camera 85 is used to read the scale of the depth measuring rope 83.

[0077] In the process of measuring the depth of the crack by the depth measuring rope 83, the scale value of the depth measuring rope 83 can be read by the camera 85 at any time, and the frequency of data change can be used to judge whether the weight 84 touches the inner wall of the crack during the falling process and whether the weight 84 touches the bottom. When the scale of the depth measuring rope 83 changes suddenly in a certain time unit during the falling process of the weight 84, it can be judged that the falling of the weight 84 is affected.

[0078] Please refer to Figures 1-2 In the embodiment, the hydraulic geological crack measuring device comprises an angle measuring device 9, and the angle measuring device 9 is installed on the scale rod 3.

[0079] In the measuring process, the inclination angle of the scale rod 3 can be judged by the angle measuring device 9, so that the scale rod 3 can be kept in a horizontal state when the width data value is read.

[0080] As one of the parallel schemes of the embodiment, the angle measuring device 9 can adopt a bubble level, and the length direction of the bubble level extends along the length direction of the scale rod 3. The level of the scale rod 3 is judged by the bubble of the bubble level.

[0081] As one of the parallel schemes of the embodiment, the angle measuring device 9 comprises an inclination sensor or a level sensor installed on the scale rod 3, and a control system (such as a single-chip microcomputer or a PLC) is arranged on the vehicle frame 11 and connected to the vertical linear drive 23 in signal, so that when the scale rod 3 is inclined, the angle measuring device 9 transmits the information of the inclination angle to the control system, the control system calculates the length of the vertical linear drive 23 to be adjusted according to the inclination angle, the control system outputs a control signal to the control system of the vertical linear drive 23, and the vertical linear drive 23 is adjusted in extension and contraction according to the control signal, so that the scale rod 3 returns to the horizontal state through continuous feedback and adjustment.

[0082] Working principle: when the water conservancy ring geological fracture measuring device needs to be moved, the vehicle frame 11 can be directly pushed to realize the movement of the whole device; during the process, the measuring rod 5 is in a downward movement state relative to the fixed rod 4. Alternatively, by applying force to the other end of the rotating rod 73, the two fixed rods 4 are simultaneously rotated about the scale rod 3 as the center axis, until the two fixed rods 4 are in an upward inclined state, so that the measuring rod 5 is on the upper side relative to the corresponding fixed rod 4. After the rotating rod 73 is rotated to the position, the positioning rod 76 is simultaneously inserted into the positioning wheel 74 and the positioning block 75, which can ensure the height of the rotating rod 73 and the upward inclined state of the two fixed rods 4 at all times. At this time, the measuring rod 5 can be prevented from contacting the ground due to natural downward sliding, so as to realize the movement of the whole device.

[0083] Measurement mode a: when the vehicle frame 1 is parked on a flat ground beside the fracture to be measured during measurement, the whole measuring device is moved to one side of the fracture to be measured by moving the vehicle frame 1, so that the scale rod 3 is initially placed horizontally above the fracture. Then, by applying a pushing force or a pulling force to the other end of the rotating rod 73, the two fixed rods 4 are simultaneously pushed or pulled to slide along the length direction of the scale rod 3. At the same time, by applying a torque to the other end of the rotating rod 73, the two-way screw rod 72 is driven to rotate, so that the two fixed rods 4 are simultaneously moved away from or towards each other, until the other ends of the two base plates 6 are located above the two sides of the fracture to be measured, respectively. Then, the two measuring rods 5 are simultaneously moved downward relative to the two fixed rods 4, until the two base plates 6 abut against the two sides of the fracture to be measured, respectively. After that, by applying a torque to the other end of the rotating rod 73, the two-way screw rod 72 is driven to rotate, so that the two fixed rods 4 are simultaneously slid away from each other along the length direction of the scale rod 3, until the lower ends of the two measuring rods 5 abut against the inner walls of the two sides of the fracture, respectively. At this time, the width value of the fracture can be read from the scale on the scale rod 3.

[0084] Measurement mode b: when the mobile frame 1 is parked on an inclined ground during measurement, the ground where the mobile frame 1 is parked is inclined downward or upward relative to the crack, the whole measuring device is moved to one side of the crack to be measured by moving the mobile frame 1, so that the scale rod 3 is initially horizontally placed above the crack, and then the vertical linear drive 23 is started to drive the scale rod 3 to rotate in the vertical plane with the rotating connection point of the support rod 22 as the midpoint until the scale rod 3 is horizontal (at this time, the bidirectional screw 72 is horizontal, and the rotating rod 73 is inclined, and the rotating rod 73 can be first separated from the bidirectional screw 72), then the other end of the rotating rod 73 is pushed or pulled to drive the two fixed rods 4 to slide along the length direction of the scale rod 3 at the same time, and the other end of the rotating rod 73 is twisted to drive the two fixed rods 4 to move away from each other or towards each other at the same time, so that the other end of the two base plates 6 is located above the two sides of the crack to be measured respectively, then the two measuring rods 5 are simultaneously slid downward relative to the two fixed rods 4, so that the two base plates 6 abut on the two sides of the crack to be measured respectively, and then the other end of the rotating rod 73 is twisted to drive the two fixed rods 4 to slide away from each other along the length direction of the scale rod 3, so that the lower ends of the two measuring rods 5 abut on the inner walls of the two sides of the crack at the same time, and at this time, the width value of the crack can be read through the scale on the scale rod 3.

[0085] Measurement mode c: when the mobile frame 1 is parked on an inclined plane along the extension direction of the crack during measurement, the measurement mode is the same as that when the mobile frame 1 is parked on a flat ground.

[0086] Measurement mode d: when the mobile frame 1 is parked on an inclined plane along the extension direction of the crack, and the ground where the mobile frame 1 is parked is inclined downward or upward relative to the crack, measurement mode a and measurement mode b are combined.

[0087] For the above measurement modes, in order to move the mobile frame 1 to one side of the crack to be measured, the positioning rod 76 is first separated from the positioning block 75, the other end of the rotating rod 73 is twisted to drive the two fixed rods 4 to rotate around the scale rod 3 as the center axis until the two fixed rods 4 are in an upward inclined state, so that the measuring rod 5 is on the upper side relative to the corresponding fixed rod 4.

Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
