[0002] As an indispensable heavy lifting equipment in the construction industry, the safety of tower cranes is directly related to the lives of construction workers and the quality of projects. Verticality detection is an important link to ensure the safe use of tower cranes. Traditional verticality detection methods mainly rely on optical measuring equipment such as theodolites for one-time detection after the installation of tower cranes. However, with the increase in high-rise buildings and the complexity of the construction environment, the existing technologies have obvious deficiencies in terms of real-time performance and stability.

[0003] For example, the Chinese patent with the publication (announcement) number CN218937415U discloses a verticality detector that can detect in real time. The adjustment component of this utility model can quickly adjust the position of the detection component, thereby achieving quick calibration and facilitating maintenance.

[0004] However, tower cranes will generate continuous vibrations during hoisting operations and under the action of wind. The detection device in the above solution is difficult to maintain long-term stability. Although the calibration is relatively simple, it needs to be calibrated frequently, which will also waste a lot of manpower and time. Therefore, the solution of this application provides a tower body verticality detection device for the detection of a building tower crane. Content of the Utility Model

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0026] This application provides a tower body verticality detection device for the detection of construction tower cranes, mainly used to solve the problem that tower cranes will generate continuous vibrations during hoisting operations and under the action of wind, and the detection devices in the prior art are difficult to maintain long-term stability. Although the calibration is relatively simple, frequent calibration is required, which will also waste a lot of manpower and time. The following technical solutions are provided and will be described in detail in combination with Figures 1 - 4 for a detailed description:

[0027] A tower body verticality detection device for the detection of construction tower cranes mainly includes a base 1 and a tower body main body 2 vertically installed on the base 1. Two installation mechanisms 3 are installed on the tower body main body 2, which are distributed up and down and on the same vertical line to ensure the verticality of the detection. An infrared transmitter 4 is installed on one of the installation mechanisms 3, and an infrared receiver 5 corresponding to the infrared transmitter 4 is installed on the other installation mechanism 3. The two are correspondingly arranged to achieve accurate verticality detection. Among them, the installation mechanism 3 includes a fixed sleeve 31, an angle-adjustable connecting block 32, and a shock-absorbing component 33 connected between the fixed sleeve 31 and the connecting block 32. The infrared transmitter 4 is installed on one of the connecting blocks 32, and the infrared receiver 5 is installed on the other connecting block 32. In this solution, the straight alignment of the infrared transmitter 4 and the infrared receiver 5 improves the accuracy of verticality detection. The shock-absorbing component 33 effectively absorbs the vibration of the tower body, reduces the deviation of the device, enhances the stability. The angle-adjustable connecting block 32 and the bubble level 325 make the equipment adjustment and calibration more convenient and fast. Due to the shock-absorbing design, the situation of frequent calibration is reduced, thus reducing the maintenance cost.

[0028] Specifically, please refer to Figure 2 , Figure 3 and Figure 4 , the fixed sleeve 31 includes two semi-circular ring plates 311. At both ends of the arc-shaped opening of the semi-circular ring plate 311, connecting plates 312 are fixed. The connecting plates 312 at both ends of the two semi-circular ring plates 311 correspond one by one. The corresponding two connecting plates 312 are fixed by bolts. The openings of the two semi-circular ring plates 311 are opposite, and they are sleeved on the tower body main body 2 in an opposing manner, and the connecting plates 312 are fixed by bolts, so that the fixed sleeve 31 can be fixed to the tower body main body 2. Through the design of the fixed sleeve 31, the connection stability between the detection device and the tower body main body 2 is enhanced. The design of the semi-circular ring plate 311 and the connecting plate 312 allows for the quick assembly and disassembly of the fixed sleeve 31, facilitating installation and maintenance; a rubber anti-slip pad 313 is installed on the opening side of the semi-circular ring plate 311. On the side of the rubber anti-slip pad 313 facing away from the semi-circular ring plate 311, anti-slip lines are provided. The design of the rubber anti-slip pad 313 and the anti-slip lines provides additional friction to prevent the fixed sleeve 31 from sliding or shifting during use. The use of the rubber anti-slip pad 313 improves the durability of the fixed sleeve 31 and reduces the wear caused by long-term use.

[0029] In this embodiment, please refer to Figure 3 and Figure 4, the shock absorption assembly 33 includes a first shock absorber 331 horizontally fixed on the outer side of one of the semi-circular ring plates 311. The number of the first shock absorbers 331 is two and they are symmetrically arranged to ensure balanced and uniform shock absorption effect. An integral mounting block 332 is connected between the other ends of the two first shock absorbers 331 to ensure that the force on the first shock absorbers 331 is evenly transmitted to the mounting block 332. The connecting block 32 is hinged to the mounting block 332. A first spring 333 is connected between one of the semi-circular ring plates 311 and the mounting block 332 to provide additional elastic support and buffering. A mounting groove 334 is formed on the side of the mounting block 332 facing the semi-circular ring plate 311. A vertically arranged device plate 335 slides inside the mounting groove 334. The other ends of the two first shock absorbers 331 are both fixed to the device plate 335. Second shock absorbers 336 are connected between the upper and lower sides of the device plate 335 and the upper and lower inner walls of the mounting groove 334. A guide rod 337 is connected between the upper and lower inner walls of the mounting groove 334. The device plate 335 is movably sleeved on the guide rod 337. A second spring 338 sleeved on the guide rod 337 is connected between the inner wall of the device plate 335 and the mounting groove 334. In this solution, the settings of the first shock absorber 331 and the second shock absorber 336 provide effective shock absorption performance, reducing the influence of the vibration of the tower body main body 2 on the detection device. The settings of the first spring 333 and the second spring 338 allow the shock absorption system to adapt to different vibration amplitudes and frequencies. By reducing the vibration influence, the accuracy of the verticality detection is improved. The guide rod 337 ensures the stable movement of the device plate 335 in the vertical direction, preventing lateral offset. By reducing the offset of the detection device caused by vibration, the operation safety of the tower crane is improved. It should be noted that the first shock absorber 331 is used to weaken the vibration in the horizontal direction, and the second shock absorber 336 is used to weaken the vibration in the vertical direction. Both the first shock absorber 331 and the second shock absorber 336 are existing structures and will not be elaborated here.

[0030] Further, please refer to Figure 3 and Figure 4 , two positioning blocks 339 are installed on the side of the mounting block 332 facing away from the mounting groove 334. An articulated block 321 movably arranged between the two positioning blocks 339 is fixed on the connecting block 32. A horizontally integral threaded rod 322 is movably inserted through the two positioning blocks 339 and the articulated block 321. A fastening block 323 is fixed at one end of the threaded rod 322. A nut 324 is threadedly sleeved on the threaded rod 322. During adjustment, by rotating the nut 324, the fastening block 323 is not in contact with one of the positioning blocks 339. At this time, the connecting block 32 can be rotated for adjustment. After the adjustment is completed, rotate the nut 324 until the fastening block 323 is in tight contact with one of the positioning blocks 339 and the nut 324 is in tight contact with the other positioning block 339, then the connecting block 32 can be fixed. The combined use of the threaded rod 322 and the nut 324 provides precise adjustment ability, allowing the operator to finely adjust the angle of the connecting block 32 for calibration.

[0031] Further, please refer to Figure 2 、 Figure 3 and Figure 4 , a bubble level 325 is provided on the connecting block 32. The bubble level 325 provides an intuitive method to check and ensure the level state of the detection device, thereby improving the installation accuracy. By observing the bubble level 325, the operator can quickly determine whether the device is level, simplifying the adjustment process.
