Description

Technical Field

[0001] The utility model relates to the technical field of crane track measurement, in particular to a track deformation measuring device. Background Art

[0002] As cranes develop toward larger tonnage and larger spans, the length and spacing of their operating tracks are also expanding, placing new demands on equipment installation, inspection, and maintenance. Cranes often operate under heavy loads, coupled with factors such as ground and wall settlement and deformation. In severe cases, the tracks can experience lateral and longitudinal deformation, with the height difference between single and double tracks exceeding limits, or the spacing between the two tubes exceeding limits. This can cause friction in the metal structure during operation, accelerating wear of the moving mechanism, increasing the clearance, shortening the service life, and even causing the crane's travel mechanism to become unstable and derail. The maintenance of crane tracks plays a vital role in the safe operation of cranes, making it particularly important to inspect crane tracks to ensure a safe operating environment.

[0003] Currently, crane track inspections are primarily performed manually, using handheld laser rangefinders, steel tape measures, levels, and other measuring instruments. This manual inspection process is complex and cumbersome, and the crane tracks are often erected in mid-air, requiring inspectors to work at height and move equipment along the tracks, which is highly dangerous. Furthermore, inspection efficiency is low, and accuracy cannot be guaranteed. Utility Model Content

Optionally, the intelligent total station 201 and the laser rangefinder 202 can also be installed on the first mounting platform 101 without the need for the second mounting platform 102. The purpose does not deviate from the design concept of the utility model and should fall within the protection scope of the utility model.

[0048] According to an embodiment provided by the present utility model, Figure 1 and Figure 2 As shown, the bracket 1 includes a support leg 103 and a support rod 104. There are multiple support legs 103, and the upper ends of the multiple support legs 103 are respectively connected to the lower ends of the support rod 104. The first mounting platform 101 can be rotatably installed on the upper end of the support rod 104 along the vertical line of its own axis, and the second mounting platform 102 is installed on one side of the support rod 104.

[0049] In this embodiment, the bracket 1 includes a support leg 103 and a support rod 104, and there are multiple support legs 103. Preferably, the number of support legs 103 is three, and the horizontal angle between each support leg 103 is 120°. The upper end of each support leg 103 is respectively connected to the lower end of the support rod 104, and the first mounting platform 101 can be rotatably installed on the upper end of the support rod 104 along the vertical line of its own axis, thereby ensuring that the first mounting platform 101 can rotate in space on the support rod 104, and the second mounting platform 102 is installed on the side of the support rod 104 below the first mounting platform 101.

[0050] According to an embodiment provided by the present utility model, Figure 2 As shown, the first mounting platform 101 is equipped with a servo motor 1011 and an encoder 1012. The servo motor 1011 and the encoder 1012 are located outside the bottom of the first mounting platform 101 and are used to automatically adjust the tilt angle of the first mounting platform.

[0051] In this embodiment, the closed-loop control connection formed by the servo motor 1011 and the encoder 1012 can automatically adjust the tilt angle of the first mounting platform 101 according to a pre-set algorithm.

[0052] The servo motor 1011 is connected to the bracket 1 through a transmission, and the encoder 1012 receives and converts the signal. The servo motor 1011 is controlled to control the first mounting platform 101 to adjust the tilt angle, so that the bracket 1 has leveling and automatic adjustment functions, thereby improving the intelligence level of the track deformation measuring device and effectively improving the efficiency of track detection work.

[0053] According to an embodiment provided by the present utility model, Figure 2As shown, the second mounting platform 102 is equipped with a bubble leveler, which is used to manually adjust the tilt angle of the second mounting platform 102 .

[0054] In this embodiment, the second mounting platform 102 is equipped with a bubble leveler, and the inspection staff can adjust the inclination angle of the second mounting platform 102 by adjusting the bubble leveler, so that the bracket 1 has a leveling function.

[0055] According to an embodiment provided by the present utility model, Figure 1 and Figure 3 As shown, the remote control car 3 is also equipped with a spotlight 301, which is installed on the body of the remote control car 3.

[0056] In this embodiment, a spotlight 301 is also installed on the body of the remote control vehicle 3. If the measurement and detection environment is very dim, the spotlight 301 can provide sufficient brightness for the reflective prism 401, thereby improving the overall applicability of the track deformation measuring device provided in this embodiment, and can fully adapt to measurement and detection conditions under any conditions.

[0057] According to an embodiment provided by the present utility model, Figure 3 As shown, the remote control car 3 is also provided with a wireless receiver.

[0058] In this embodiment, the remote control vehicle 3 is also equipped with a wireless receiver that can receive signals from the controller 5, thereby controlling the remote control vehicle 3 to move forward or backward on the track 6 being tested. By replacing the need for human operators to stand on the track 6 for testing, the remote control vehicle 3 improves track testing efficiency, reduces the workload of operators, and enhances safety during the testing process, while also improving measurement accuracy.

[0059] The measurement principle used by the track deformation measurement device provided in this application is as follows: Figure 4 As shown, during measurement, the intelligent total station 201 and the laser rangefinder 202 are installed on the bracket 1, and the bracket 1 is leveled. The three are connected to the controller 5 and the memory through a data cable, the remote control car 3 is placed on the measured track 6, and the first mounting platform 101 on the bracket 1 where the intelligent total station 201 is mounted is adjusted so that the intelligent total station 201 is aligned with the reflective prism 401 on the remote control car 3. The system measurement mode is turned on by the controller 5. At this time, the laser rangefinder 202 measures the horizontal distance l between the reflective prism 401 and the bracket 1. The height d of the reflective prism 401 and the height h of the bracket 1 are known fixed values. These two fixed values ​​are input into the system, and the system can automatically calculate the horizontal angle α according to the set algorithm. The controller 5 controls the servo motor 1011 and the encoder 1012 to adjust the tilt α of the first mounting platform 101 where the intelligent total station 201 is mounted. This algorithm is used to realize the real-time alignment of the intelligent total station 201 with the prism.

[0060] The surveyor controls the remote control vehicle 3 via the controller 5 to run on the track 6 to be measured. After running to the position of the point to be measured, the surveyor controls the intelligent total station 201 to measure the three-dimensional coordinates of the reflective prism 401 and record them in the memory. After measuring each point to be measured on the track in this way, the three-dimensional coordinates of all the points to be measured will be stored in the memory. The three-dimensional coordinate data of these points to be measured can be used to draw the trajectory curve of the center line of the surface of the track 6 to be measured, and the height, horizontality and other data of each point of the track 6 to be measured can also be measured through the data of these points to be measured. Track deformation measurement and detection using the above method can improve the efficiency of track detection work, reduce the labor intensity of track detection personnel, improve the safety of inspection work, enhance the level of inspection and testing services, and promote the safe production of lifting machinery. Its economic and social benefits are very huge.

[0061] like Figure 5 As shown, the track measurement deformation device provided by the present invention can also be increased with a ceiling rail remote control car 7, which can be installed on a ceiling rail 8 (i.e., a track installed in the air) and can run along the extension direction of the ceiling rail 8. The ceiling rail remote control car 7 is equipped with a second reflecting prism, a second spotlight, a second laser rangefinder 701 and a signal receiver. A second reflector 801 is also used in conjunction with the ceiling rail remote control car 7. The reflector 402 is integrated with a laser emitter that can emit laser light so that the surveyor can measure the horizontal distance from the mark on the ground made by the laser to the intelligent total station 201 based on the mark. During measurement, the remote-controlled car 7 and the second reflector 801 are mounted on the rail 8. Based on the mark on the ground illuminated by the laser on the second reflector 801, the horizontal distance l2 from the marked point to the intelligent total station 201 is measured. The system controls the operation of the remote-controlled car 7 based on the horizontal distance l1 between the remote-controlled car 7 and the second reflector 801 measured by the second laser rangefinder 701 on the remote-controlled car 7, so that l1+l2 always equals l, thereby achieving synchronization between the remote-controlled car 7 and the remote-controlled car 3. At the same time, referring to a method similar to measuring the α angle, the tangent value of the horizontal angle between the second reflective prism on the remote-controlled car 7, the intelligent total station 201, and the second reflective prism on the remote-controlled car 7 is obtained by subtracting the height h1 of the remote-controlled car 7 from the height difference H between the rail 8 and the measured track 6, and then dividing it by the horizontal distance l between the remote-controlled car 7 and the remote-controlled car 3 and the intelligent total station 201. The measurement principle is as follows: Figure 5 Similarly, through the closed-loop control formed by servo motor 1011 and encoder 1012, intelligent total station 201 is controlled to automatically align with the second reflective prism on the remote-controlled vehicle 7 and read the three-dimensional coordinates of the measured position, thereby calculating the trajectory curve of the overhead rail 8. By comparing the trajectory data of the overhead rail 8 with the trajectory data of the measured track 6, the deviation between the two is calculated.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
