[0033] The following will make a detailed description of the three embodiments of this application with reference to the accompanying drawings.

[0034] The first embodiment:

[0035] Figure 1 - Figure 5 As shown, a crack measuring device for a factory building floor includes a base 1 installed on a mobile platform. The mobile platform uses a mobile device in the prior art, and a suitable mobile device in the prior art is selected by those skilled in the art for setting, such as an AGV cart; the measuring device on it is driven by the mobile platform to move for crack measurement work within a specified range;

[0036] A lifting box 2 is provided on the base 1, and a pair of electric push rods 11 are connected between the base 1 and the lifting box 2; both ends of the lifting box 2 are rotatably connected with adjusting arms 3. A motor matching the adjusting arms 3 is installed in the lifting box 2. The adjusting arm 3 includes a pair of electric telescopic rods 31. Fixed blocks 32 are connected to the telescopic ends of the pair of electric telescopic rods 31. An electric guide rail group 4 is rotatably connected between the pair of fixed blocks 32. A sub-motor for driving the electric guide rail group 4 to rotate is installed on the fixed block 32. A pair of measuring units 5 are slidably connected to the electric guide rail group 4;

[0037] The measuring unit 5 includes a mounting shell 51. A measuring probe 52 is fixedly connected to the lower end of the mounting shell 51. A docking ring 53 matching the measuring probe 52 is connected to the upper end of the mounting shell 51; the measuring probe 52 is close to the lower surface of the mounting shell 51 and does not protrude outside the lower surface of the mounting shell 51;

[0038] When this solution works, first drive the adjusting arm 3 to rotate through the motor, so that the measuring unit 5 moves away from the base 1. At the same time, the electric telescopic rod 31 works to drive the electric guide rail group 4 close to the ground. Then, by controlling the displacement of the measuring unit 5, the measuring probe 52 measures the cracks on the ground;

[0039] A receiving groove is opened at the lower end of the lifting box 2, and a pair of docking plugs 21 matching the docking ring 53 are installed in the receiving groove; when the docking ring 53 is docked with the docking plug 21, the measuring probe 52 is charged and data is transmitted;

[0040] After the measuring unit 5 is received between the base 1 and the lifting box 2, the lifting box 2 descends under the drive of the electric push rod 11 until the docking plug 21 is docked with the docking ring 53. At this time, the charging and data transmission of the measuring probe 52 are realized through the docking ring 53 and the docking plug 21. A storage battery for supplying power to the measuring probe 52 is installed in the installation shell 51, and the measuring probe 52 is electrically connected to both the measuring probe 52 and the storage battery; a power distribution module for controlling charging and a data acquisition module for transmitting data are installed in the lifting box 2. An elastic cable (not shown in the figure) is connected between the base 1 and the lifting box 2, and data and charging are transmitted to the external system through the elastic cable. The base 1 is electrically connected to the external power supply, and those skilled in the art use the existing technology to set up and connect the above-mentioned power distribution module and data acquisition module;

[0041] The measuring probes 52 on the two measuring units 5 are an image acquisition device and a laser sensor respectively.

[0042] A placement groove matching the measuring unit 5 is opened at the upper end of the base 1; when the measuring unit 5 is driven to the placement groove, the bottom surface of the measuring unit 5 is parallel to the placement groove, and at this time the measuring unit 5 is displaced to the initial position on the electric guide rail group 4 (the initial position is set as: the maximum displacement at the left end or the maximum displacement at the right end of the electric guide rail group 4);

[0043] The electric guide rail group 4 includes a pair of screw guide rails 41. An intermediate block 42 is connected between the pair of screw guide rails 41. An LED lighting lamp is installed at the bottom end of the intermediate block 42. The screw guide rail 41 includes a smooth rod and a screw rod rotatably connected between a pair of brackets. A servo motor matching the pair of screw rods is installed in the intermediate block 42. A sliding hole and a threaded hole matching the smooth rod and the screw rod are opened on the installation shell 51; the power output end of the servo motor is installed with a driving gear meshing with a pair of transmission gears. The transmission gears are rotatably connected in the intermediate block 42, and the two transmission gears are respectively fixed to the two screw rods; by controlling the servo motor to work, the pair of measuring units 5 move synchronously;

[0044] A limiting strip is fixedly connected to the upper end of the base 1. A convex block is connected between the outer wall of the lifting box 2 and the movable end of the electric push rod 11. The distance between the two convex blocks matches the length of the limiting strip. The limiting strip is used to limit the rotation angle of the adjusting arm 3 to ensure that when the measuring unit 5 is received between the base 1 and the lifting box 2, its position is not easily offset.

[0045] This embodiment can achieve high-precision measurement of cracks on the factory floor, automatically adjust the device state according to environmental data, and provide limited protection for the measuring unit 5 when no measurement work is carried out, ensuring stable operation for a long time in harsh environments. Through the coordinated work of components such as the motor, electric telescopic rod 31, and electric guide rail group 4, flexible displacement and precise measurement of the measuring unit 5 are realized.

[0046] In addition, through the design of the docking plug 21 and the docking ring 53, convenient charging and data transmission of the measuring probe 5 are realized, further improving the measurement efficiency and accuracy.

[0047] The second embodiment:

[0048] Among them, the same or corresponding components as those in the first embodiment adopt the corresponding reference numerals of the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The differences between the second embodiment and the first embodiment are as follows:

[0049] Figure 5 - Figure 6 As shown, through holes are provided at both ends of the placement groove. A rotating shaft is rotatably connected in each of a pair of through holes. A cleaning belt (the cleaning belt is in the shape of a conveyor belt) is connected between the pair of rotating shafts. Brush layers for blocking the through holes are provided on the through holes, and one end of the brush layer is in contact with the cleaning belt (the brush is not shown in the figure). A driving motor 12 for driving the cleaning belt is installed in the base 1. The cleaning belt includes a stain-resistant section, a placement section, and a cleaning section. The cleaning section is made of the cleaning cloth fabric of the prior art, and both the stain-resistant section and the placement section are made of the three-proof fabric of the prior art.

[0050] Before the measuring unit 5 is received into the placement groove, the driving motor 12 operates to move the cleaning section to the placement groove. The cleaning section is used to perform a cleaning operation on the measuring probe 52 when the measuring unit 5 is received into the placement groove. During the cleaning operation, the driving motor 12 drives the cleaning section to move back and forth left and right a set number of times. After the cleaning operation is completed, the driving motor 12 is driven to operate to move the placement section to the placement groove, and the measuring unit 5 is in contact with the placement section to close the measuring probe 52.

[0051] When the measuring unit 5 moves away from the placement groove for crack measurement work, the driving motor 12 operates to retract the placement section into the base 1; then the stain-resistant section is driven to move into the placement groove. At this time, both the placement section and the cleaning section are located within the base 1, thereby preventing the cleaning section and the placement section from being contaminated by the external environment and avoiding contamination when the measuring probe 52 is retracted into the placement groove.

[0052] The cleaning belt of this embodiment realizes the automatic cleaning function of the measuring probe 52, reduces the cumbersome manual cleaning, and improves the cleaning efficiency and cleaning effect at the same time. When the measuring unit 5 is away from the base 1 for crack measurement work, the cleaning section is retracted into the base, avoiding the pollution of the cleaning section by the external environment and ensuring the cleaning effect and service life of the cleaning section.

[0053] The design of the cleaning belt also takes into account the cooperation of the stain-resistant section, the placement section and the cleaning section, so that when the measuring unit 5 is retracted into the placement groove, the cleaning section can accurately move to the placement groove to clean the measuring probe 52, and when the measuring unit 5 moves away from the placement groove, the cleaning section can be timely retracted into the base 1, avoiding unnecessary pollution and damage; improving the automation degree of the measuring device and ensuring the stable operation of the measuring device in harsh environments.

[0054] The third embodiment:

[0055] Among them, the same or corresponding components as those in the first embodiment adopt the corresponding reference numerals of the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The difference between this third embodiment and the first embodiment is as follows:

[0056] Figure 7 As shown, it further includes an auxiliary measurement system. The auxiliary measurement system includes a processor, and a control module, a data processing module and a monitoring module are connected to the processor;

[0057] The monitoring module is used to collect monitoring data, and the monitoring data includes environmental temperature, humidity, dust condition and ground vibration data;

[0058] The data processing module is used to process and analyze the monitoring data, and adjust the state of the measuring device according to the monitoring data. The state of the measuring device includes a measurement state and a protection state;

[0059] The control module is used to control the specified device to adjust the state of the measuring device according to the analysis result of the data processing module;

[0060] In the measurement state, the motor drives the adjusting arm 3 to rotate in a direction away from the lifting box 2. At the same time, the electric telescopic rod 31 and the sub-motor operate to displace the electric guide rail group 4 close to the ground and parallel to the ground;

[0061] In the protected state, the motor drives the adjusting arm 3 to approach the lifting box 2. Meanwhile, the electric telescopic rod 31 and the auxiliary motor work to place the measuring unit 5 on the upper surface of the base 1. Then, the electric push rod 11 controls the lowering of the lifting box 2 so that the docking plug 21 is docked with the docking ring 53. At this time, the measuring unit 5 is clamped between the lifting box 2 and the base 1.

[0062] When the system of this solution works, the environmental temperature, humidity, dust condition and ground vibration data are detected by the environmental sensor. When the measuring device of this solution is not performing measurement work, it is default set to the protected state to avoid the measuring unit 5 being polluted by the environment due to long-term exposure.

[0063] Among the detected environmental data, when any data exceeds the set value (i.e., the environmental parameters change), or at every set time interval, the measuring device is adjusted to the measuring state to perform a measurement work. In the measuring state, it is detected by the measuring unit whether there are cracks in the preset measuring area and the cracks are measured. When measuring, the ground image is collected by the image acquisition device, and then the collected image is subjected to image recognition to identify the planar size of the cracks; when measuring, the depth of the cracks is also measured by the laser sensor.

[0064] When the image acquisition device and the laser sensor perform detection, the two measuring units 5 are driven to displace by the electric guide rail group 4, and the whole measuring device is driven to displace by the moving platform to ensure that the measuring unit 5 can complete a comprehensive crack measurement of the set area.

[0065] After the measurement work is completed, the measuring device is restored to the protected state; it is realized that when the external environment changes to the set warning value, a ground crack measurement can be quickly performed to timely detect whether the cracks expand when the external data changes.

[0066] This embodiment can achieve efficient and accurate measurement of the cracks on the factory building ground, and automatically adjust the device state according to the real-time monitored environmental data, thereby effectively avoiding the interference of environmental factors on the measurement results and ensuring the accuracy and reliability of the measurement data; in the protected state, the measuring unit is properly protected, the service life of the device is extended, and at the same time, the safety and stability of the measurement work are improved. Through the collaborative work of the image acquisition device and the laser sensor, a comprehensive measurement of the planar size and depth of the cracks is realized, providing strong data support for the maintenance and repair of the factory building ground.

[0067] In summary, this solution realizes the efficient, automatic measurement of the cracks on the factory building ground and the self-protection of the equipment. It is convenient to automatically adjust the device state according to the real-time monitored environmental data and the preset process to achieve automatic measurement. At the same time, when the measurement work is not performed, the measuring unit 5 can be properly protected, which is easy to extend the service life of the device and improve the safety and stability of the measurement work.

[0068] Combined with the current actual requirements, the above-mentioned implementation manners adopted in this application, the scope of protection is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the scope of protection of the present invention.
