Description

Technical Field

[0001] This utility model relates to the technical field of crack measurement tools, specifically a geological disaster crack measurement device. Background Technology

[0002] Geological disasters refer to geological processes or phenomena that cause loss of human life and property and damage to the environment under the influence of natural or human factors. Although landslides, collapses, and debris flows are sudden and highly dangerous, they often have obvious precursors. Carrying out mass monitoring and prevention of geological disasters, and conducting simple measurements of landslides, collapses, and cracks in buildings to understand the stability of landslides and collapses, is an effective method for avoiding casualties in my country.

[0003] Chinese patent provides a geological disaster crack measuring device, publication number CN212408166U, which includes two sets of universal wheels. Each set of universal wheels has a base plate on its top. Each set of base plates has a horizontal plate on its opposite side. Each set of horizontal plates has through-holes on both sides, and each set of mounting holes has a fixed threaded sleeve inside its cavity. Each set of threaded sleeves has a movably inserted screw rod inside its cavity, with the top and bottom of the screw rod extending out of the threaded sleeve cavity. Each set of screw rods has a bearing seat fixedly fitted at its bottom, and each set of bearing seats has a top pressure plate at its bottom. Each set of screw rods has a handle at its top. Each set of base plates has a telescopic rod at its top center, and each set of telescopic rods has a sleeve fitted at its top. Each set of sleeves has a connecting block on its opposite side, and a disassembly measuring device is provided between the two sets of connecting blocks. This device facilitates mobile measurement, improves measurement efficiency, and is easy to disassemble and carry.

[0004] However, the movement of the outer fixing sleeve one and the outer fixing sleeve two requires manual close-range manipulation. When the gap between the cracks to be measured is large, manual manipulation poses certain safety hazards. In addition, the device uses manual visual inspection, which has low accuracy. When the lighting conditions are low or at night, it is impossible to clearly observe the measurement data, thus making it impossible to continue the measurement work. Therefore, it is necessary to provide a geological disaster crack measurement device. Utility Model Content

[0005] The purpose of this invention is to provide a geological disaster crack measurement device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a geological disaster crack measuring device, comprising two bases, a first lead screw rotatably mounted on each base, and a lifting block threadedly connected to the first lead screw; a scale plate fixedly mounted between the two lifting blocks, two sliding sleeves slidably mounted on the scale plate, a measuring plate fixedly mounted at the bottom of each sliding sleeve, a first fixing block fixedly mounted on one side of each sliding sleeve, a second lead screw rotatably connected to the first fixing block, and a second fixing block fixedly mounted on one side of each lifting block, the second lead screw being threadedly connected to the second fixing block; a laser emitter and a laser receiver are respectively mounted on the two measuring plates, and a controller, a display, and a rechargeable lithium battery pack are respectively mounted on the two lifting blocks.

[0007] Preferably, a cone is fixedly provided at the bottom of the base, and a foot pedal is fixedly provided on one side of the base.

[0008] Preferably, a first hand-tightening block is fixedly connected to the top of the first lead screw, and a second hand-tightening block is fixedly connected to one end of the second lead screw.

[0009] Preferably, both the laser emitter and the laser receiver are signal-connected to the controller, and the controller is electrically connected to the display.

[0010] Preferably, the rechargeable lithium battery pack is electrically connected to the laser emitter, laser receiver, controller, and display, respectively.

[0011] Preferably, a first bracket and a second bracket are fixedly installed on the two lifting blocks respectively, the display is installed on the first bracket, and the rechargeable lithium battery pack is installed on the second bracket.

[0012] Preferably, the controller is mounted on the lifting block near the first support.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This geological disaster crack measuring device rotates two second screw rods by rotating two second hand-tightening blocks, which in turn pushes or pulls two sliding sleeves under the action of the screw threads. By moving the two sliding sleeves, the two measuring plates can be pressed tightly against the sidewalls at both ends of the crack, thus facilitating the measurement work. When adjusting the position of the measuring plates, the measuring personnel only need to stand on the ground at both ends of the crack and on one side of the two first screw rods to operate, which greatly improves the safety of the measurement work and effectively avoids the occurrence of safety accidents.

[0015] 2) This geological hazard crack measurement device uses a laser transmitter and a laser receiver installed on two measuring plates to calculate the distance by measuring the round-trip time or phase difference of the laser beam, generating raw data. The controller receives the raw data and performs correction, calculation, and storage. The display receives the signal from the controller and converts the calculated and corrected data into readable numbers and displays them on the screen. This allows the measurement personnel to intuitively observe the crack measurement data, reduces human reading errors, and improves measurement accuracy. At the same time, the laser rangefinder can maintain normal operation in poor lighting conditions or at night, and the penetrating power of the laser beam ensures that obstacles within a certain range will not affect the measurement results.

[0021] 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. Example

[0022] Combination Figures 1-4 A geological disaster crack measuring device includes two bases 1, with a cone 2 fixedly installed at the bottom of the base 1 and a foot pedal 3 fixedly installed on one side of the base 1.

[0023] See Figure 2Furthermore, a first lead screw 4 is rotatably mounted on the base 1, and a lifting block 6 is threadedly connected to the first lead screw 4; a scale plate 7 is fixedly mounted between the two lifting blocks 6, and two sliding sleeves 8 are slidably mounted on the scale plate 7; a measuring plate 9 is fixedly mounted at the bottom of the sliding sleeves 8; a first fixing block 10 is fixedly mounted on one side of the sliding sleeves 8; a second lead screw 11 is rotatably connected to the first fixing block 10; a second fixing block 12 is fixedly mounted on one side of the lifting block 6; the second lead screw 11 is threadedly connected to the second fixing block 12; a first hand-tightening block 5 is fixedly connected to the top of the first lead screw 4; and a second hand-tightening block 13 is fixedly connected to one end of the second lead screw 11.

[0024] Specifically, by rotating the two second hand-tightening blocks 13, the two second lead screws 11 are rotated, allowing the two sliding sleeves 8 to be pushed or pulled by the two second lead screws 11 under the action of the threads. By moving the two sliding sleeves 8, the two measuring plates 9 can be tightly attached to the sidewalls at both ends of the crack, thus facilitating the measurement work. When adjusting the position of the measuring plates 9, the measuring personnel only need to stand on the ground at both ends of the crack and on one side of the two first lead screws 4 to operate, which greatly improves the safety of the measurement work and effectively avoids the occurrence of safety accidents.

[0025] See Figures 2-4 Furthermore, it is found that a laser emitter 14 and a laser receiver 15 are respectively installed on the two measuring plates 9, and a controller 16, a display 18, and a rechargeable lithium battery pack 20 are respectively installed on the two lifting blocks 6; the laser emitter 14 and the laser receiver 15 are both connected to the controller 16 by signal, and the controller 16 is electrically connected to the display 18; the rechargeable lithium battery pack 20 is electrically connected to the laser emitter 14, the laser receiver 15, the controller 16, and the display 18 respectively; a first bracket 17 and a second bracket 19 are respectively fixedly installed on the two lifting blocks 6, the display 18 is installed on the first bracket 17, and the rechargeable lithium battery pack 20 is installed on the second bracket 19; the controller 16 is installed on the lifting block 6 near the first bracket 17.

[0026] Specifically, by installing a laser emitter 14 and a laser receiver 15 on two measuring plates 9 respectively, the distance is calculated by measuring the round-trip time or phase difference of the laser beam to generate raw data. The controller 16 receives the raw data and performs correction, calculation and storage. The display 18 receives the signal from the controller 16 and converts the calculated and corrected data into readable numbers and displays them on the screen, which makes it easier for the measuring personnel to intuitively observe the measurement data of the crack, reduces human reading errors and improves measurement accuracy. At the same time, the laser rangefinder can maintain normal operation in poor lighting conditions or at night, and the penetrability of the laser beam also ensures that obstacles within a certain range will not affect the measurement results.

[0027] In actual operation, the two first lead screws 4 are placed on both sides of the crack to be measured. The foot pedal 3 is used to insert the cone 2 into the ground, thereby fixing the base 1 on the ground. By rotating the two first hand-tightening blocks 5, the two first lead screws 4 are rotated, allowing the lifting blocks 6 threadedly connected to the first lead screws 4 to move up and down, thus facilitating the adjustment of the height of the scale plate 7. This ensures that the scale plate 7 and the two measuring plates 9 are on the same horizontal plane. By adjusting the height of the scale plate 7, the two measuring plates 9 can be inserted into the crack. Then, by rotating the two second hand-tightening blocks 13, the two second lead screws 11 are rotated, allowing the two sliding sleeves 8 to be pushed or pulled by the two second lead screws 11 under the action of the threads. By moving the two sliding sleeves 8, the two measuring plates 9 are pressed tightly against both ends of the crack. The sidewall of the crack is equipped with a laser emitter 14 and a laser receiver 15 mounted on two measuring plates 9. The laser emitter 14 emits a laser beam aimed at the other end of the crack, and the laser receiver 15 receives the emitted laser beam. The distance is calculated by measuring the round-trip time or phase difference of the laser beam to generate raw data. The controller 16 receives the raw data and performs correction, calculation and storage. The display 18 receives the signal from the controller 16 and converts the calculated and corrected data into readable numbers and displays them on the screen. This allows the measuring personnel to intuitively observe the measurement data of the crack, reduces human reading errors and improves measurement accuracy. At the same time, the laser rangefinder can maintain normal operation in poor lighting conditions or at night, and the penetrability of the laser beam also ensures that obstacles within a certain range will not affect the measurement results.
