[0034] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0035] This application discloses a detection device for the operation of engineering equipment. (Refer to...) Figures 1-4A detection device for the operation of engineering equipment includes a crossbeam 1, a fixing block 3, a connecting rope 4, a counterweight box 5, and a laser scanning rangefinder 6. The fixing block 3 is fixed on the crossbeam 1, and the laser scanning rangefinder 6 is fixed on the counterweight box 5. The counterweight box 5 is connected to the lower part of the fixing block 3 by the connecting rope 4. It also includes a traveling mechanism 2. Two sets of traveling mechanisms 2 are symmetrically installed at both ends of the crossbeam 1 for mounting the crossbeam 1 on a tower and driving the crossbeam 1 to move along the tower. The traveling mechanism 2 includes: a fixing plate 21, a first L-shaped movable frame 22, a first threaded rod 221, a power wheel 23, and a drive motor 24.

[0036] Specifically, by Figure 1 and Figure 2 As shown, the fixed plate 21 is fixed to the end of the crossbeam 1. The first L-shaped movable frame 22 is connected to the fixed plate 21 and can move relative to the fixed plate 21. The first threaded rod 221 is installed on the fixed plate 21 by thread engagement, and the end of the first threaded rod 221 passes through the fixed plate 21 and is rotatably connected to the first L-shaped movable frame 22 by bearing. The power wheel 23 is rotatably installed on the first L-shaped movable frame 22. The drive motor 24 is fixed on the first L-shaped movable frame 22 to drive the power wheel 23 to rotate. Therefore, in use, the two sets of traveling mechanisms 2 are first locked on both sides of the tower, and then the first threaded rod 221 is rotated so that the first threaded rod 221 is threaded. The action pushes the No. 1 L-shaped movable frame 22 to move, so that the power wheel 23 abuts against the tower. The power wheels 23 on both sides clamp the tower to achieve installation. During inspection, the drive motor 24 is started to drive the power wheel 23 to rotate, so that the crossbeam 1 moves along the tower. The laser scanning rangefinder 6 monitors the change in the distance between the crossbeam and the tower to achieve verticality detection of the tower. In this embodiment, the crossbeam 1 is installed on the tower by two sets of symmetrically distributed walking mechanisms 2 and the crossbeam 1 is driven to move along the tower. The connecting rope 4 can be set to a shorter length to avoid the wind affecting the accuracy of the inspection. It can also quickly perform all-round inspection of the tower, and the inspection efficiency and inspection accuracy are greatly improved.

[0037] It is worth noting that the drive motor 24 is preferably an electromagnetic brake motor. When the drive motor 24 is not powered, its output shaft cannot rotate, which is used to ensure stability.

[0038] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the walking mechanism 2 further includes a first handwheel 222, which is fixed to the end of the first threaded rod 221 away from the first L-shaped movable frame 22. The first threaded rod 221 can be easily rotated by the first handwheel 222.

[0039] Preferably, by Figure 1 and Figure 2As shown in this embodiment, a guide rod 223 is fixed on the L-shaped movable frame 22, which passes through the fixed plate 21, to guide and support the L-shaped movable frame 22 and improve its stability.

[0040] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the walking mechanism 2 further includes: a second L-shaped movable frame 25, auxiliary wheels 26, and a second threaded rod 251. The second L-shaped movable frame 25 is connected to the fixed plate 21 and can move relative to the fixed plate 21. The auxiliary wheels 26 are rotatably mounted on the second L-shaped movable frame 25. The second threaded rod 251 is mounted on the fixed plate 21 by thread engagement, and the end of the second threaded rod 251 passes through the fixed plate 21 and is rotatably connected to the second L-shaped movable frame 25 by bearings. Rotating the second threaded rod 251 causes the second threaded rod 251 to push the second L-shaped movable frame 25 to move under the thread engagement, so that the auxiliary wheels 26 abut against the tower. The auxiliary wheels 26 on both sides clamp the tower, further improving the stability of the detection device installation.

[0041] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the walking mechanism 2 further includes a second handwheel 252, which is fixed to the end of the second threaded rod 251 away from the second L-shaped movable frame 25. The second threaded rod 251 can be easily rotated by the second handwheel 252.

[0042] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, a second guide rod 253 is fixed on the second L-shaped movable frame 25, which passes through the fixed plate 21, to guide and support the second L-shaped movable frame 25 and improve the stability of the second L-shaped movable frame 25.

[0043] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown in this embodiment, anti-slip rubber sleeves 7 are fixed on both the power wheel 23 and the auxiliary wheel 26, and anti-slip protrusions 71 are evenly distributed on the circumferential surface of the anti-slip rubber sleeves 7. The anti-slip rubber sleeves 7 and the anti-slip protrusions 71 have flexibility and anti-slip effect, which further improves the stability of the detection device installation, avoids the detection device from shifting, and also prevents the detection device from accidentally slipping when idle.

[0044] Preferably, by Figure 1 and Figure 3As shown in this embodiment, the crossbeam 1 includes a hollow outer beam 11, an inner beam 12, and a manual bolt 13. The two inner beams 12 are symmetrically distributed and embedded in the hollow outer beam 11 to form a telescopic structure. A waist-shaped hole 111 is provided on the hollow outer beam 11. The manual bolt 13 passes through the waist-shaped hole 111 and is connected to the inner beam 12 by threaded engagement. When necessary, the manual bolt 13 is loosened to adjust the embedding length of the two inner beams 12, which is used to adjust the total length of the crossbeam 1 to meet the testing requirements of towers of different sizes. Then, the manual bolt 13 is tightened to lock it.

[0045] It should be noted that the drive motor 24 and the laser scanning rangefinder 6 are both commercially available conventional devices with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0047] Components not described in detail in this article are existing technologies.

[0048] The implementation principle of the detection device for the operation of engineering equipment in this application embodiment is as follows: When in use, firstly, the two sets of walking mechanisms 2 are clamped on both sides of the tower, and then the No. 1 threaded rod 221 is rotated, so that the No. 1 threaded rod 221 pushes the No. 1 L-shaped movable frame 22 to move under the threaded rotation action, so that the power wheel 23 abuts against the tower, and the tower is clamped by the power wheels 23 on both sides to realize the installation.

[0049] Rotate the No. 2 threaded rod 251, so that the No. 2 threaded rod 251 pushes the No. 2 L-shaped movable frame 25 to move under the threaded action, so that the auxiliary wheel 26 abuts against the tower. The auxiliary wheels 26 on both sides clamp the tower, further improving the stability of the detection device installation.

[0050] During the inspection, the drive motor 24 is started to drive the power wheel 23 to rotate, so that the crossbeam 1 moves along the tower. The laser scanning rangefinder 6 monitors the change in the distance between the beam and the tower, thereby realizing the verticality detection of the tower.

[0051] In this embodiment, the crossbeam 1 is installed on the tower by two sets of symmetrically distributed walking mechanisms 2, and the crossbeam 1 is driven to move along the tower. The connecting rope 4 can be set to a shorter length to avoid the wind affecting the accuracy of the test, and the tower can be quickly inspected from all directions, thus greatly improving the test efficiency and accuracy.
