[0002] Tower crane is also called tower crane, which is a rotating crane with the boom installed on the upper part of the towering tower. It has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. With the development of computer technology, Internet+ has gradually been widely used in all walks of life and work. Among them, smart construction sites are the concrete embodiment of the Internet+ concept on construction sites, and are the in-depth combination of Internet+ and traditional construction site management. By setting up monitoring devices on the tower crane, such as surveillance cameras, it is used to monitor the working status of the tower crane and the surrounding environment of the tower crane to ensure the safe operation of the tower crane and assist the driver in remote driving judgment.

[0027] Please see Figures 1 to 6An auxiliary fixing device 10 includes a mounting portion 100, a sleeve 200, a sleeve rod 300 and a locking ring 400. The mounting portion 100 is provided with a mounting rod 110, and the mounting rod 110 is fixedly mounted on the mounting portion 100 and arranged vertically downward. The mounting rod 110 and the mounting portion 100 can be connected by bolting or welding to ensure the installation strength, and a monitoring device 30 is installed on the mounting rod 110. The monitoring device 30 is a camera, etc. The monitoring device 30 is arranged vertically downward and can monitor a larger range. The sleeve 200 is connected to the mounting portion 100, and the sleeve rod 300 can be telescopically sleeved in the sleeve 200. According to the standard sections of the tower body with different cross-sectional sizes, For example, 1.2m×1.2m, 1.4m×1.4m, 1.6m×1.6m, and 2.0m×2.0m, the sleeve rod 300 can be fixed to the sleeve 200 when the cross-sectional size is the same as that of the standard section of the tower body by extending the sleeve rod 300 from the sleeve 200 or shortening the length of the sleeve rod 300. The sleeve rod 300 and the sleeve 200 can be fixed by expansion fixation or clamping fixation. The locking ring 400 is arranged at the end of the sleeve rod 300, and the locking ring 400 is opened to fix the locking ring 400 on the standard section of the tower body. The locking ring 400 is an existing device similar to a steel pipe clamp, so as to achieve the purpose of fixing the monitoring device 30 on the tower crane through the auxiliary fixing device 10.

[0028] The installation positions of the casing 200 , the casing rod 300 , the locking ring 400 and the monitoring device 30 should be set at pre-planned positions and should not affect the normal operation of the tower crane 20 .

[0029] The effect achieved:

[0030] By installing the monitoring device 30 on the auxiliary fixing device 10, the monitoring device 30 is installed more firmly and does not shake while the monitoring function of the monitoring device 30 is realized. Then the auxiliary fixing device 10 is fixed on the tower crane, which can adapt to standard tower sections with different cross-sectional sizes, and the installation and disassembly are simple and convenient, which improves the convenience of installing the monitoring device 30.

[0031] For further information, see Figure 1The sleeve 200 is provided with a fastening bolt 210 , and the sleeve rod 300 is provided with a slot 310 . The fastening bolt 210 passes through the outer wall of the sleeve 200 and extends into the slot 310 , and contacts the bottom of the slot 310 . The sleeve rod 300 is fixed to the sleeve tube 200 by snap-fitting. A threaded hole is provided on the sleeve tube 200. The fastening bolt 210 is screwed into the threaded hole and passes through the threaded hole to the groove body 310. When the sleeve rod 300 needs to be extended, the sleeve rod 300 is pulled out from the sleeve tube 200. The fastening bolt 210 moves relative to the groove. The fastening bolt 210 has a limiting function to prevent the sleeve rod 300 from deviating in the sleeve tube 200. When the sleeve rod 300 reaches a preset length, the fastening bolt 210 is continuously screwed in so that the fastening bolt 210 reaches the bottom of the groove and is tightened so that the sleeve rod 300 and the sleeve tube 200 are relatively fixed to avoid movement between the two.

[0032] As a preference, see Figure 2 and Figure 3 The mounting rod 110 includes a vertical rod 111, a mounting plate 112 and a connecting piece 113. The vertical rod 111 is connected to the mounting portion 100. The mounting plate 112 can be movably sleeved on the vertical rod 111. The connecting piece 113 is arranged on the mounting plate 112. During use, the mounting plate 112 is first removed from the vertical rod 111, and the mounting plate 112 is connected to the monitoring device 30 through the connecting piece 113. The connecting piece 113 can be connected by bolts and studs, or by snap-fitting. After installation, the mounting plate 112 is sleeved on the vertical rod 111 and fixed, and can be fixed by a pin or a snap-fitting.

[0033] Furthermore, a storage box 120 is also provided on the installation part 100, and an opening and closing door 121 and a wire outlet hole 123 are provided on the storage box 120, and a lock 122 is provided on the opening and closing door 121. For some monitoring devices 30, in order to improve the endurance of the monitoring device 30, a power supply is used to power the monitoring device 30, but in order to make the power supply waterproof, a storage box 120 is provided on the installation part 100, the opening and closing door 121 is opened, the power supply is placed in the storage box 120, the wires of the power supply are exposed through the wire outlet hole 123, and the opening and closing door 121 is closed, and the opening and closing door 121 is locked with the lock 122 to prevent the opening and closing door 121 from being opened due to wind; at the same time, a wireless receiver and other devices can also be placed in the storage box 120 to prevent rain. In addition, when the power supply in the storage box 120 is insufficient, the opening and closing door 121 is opened to replace the power supply.

[0034] For further information, see Figure 4and Figure 5 The mounting portion 100 is also provided with a wire collection member 130, which is arranged on a side close to the wire outlet hole 123. The wire collection member 130 includes a pair of baffles 131 and a plurality of wire poles 132 arranged between the pair of baffles 131. In order to prevent the exposed wires from being exposed to the sun or exposed to wind and rain for a long time, causing aging, the wires led out from the wire outlet hole 123 pass through the channel between the pair of baffles 131 and fall on the wire poles 132, which can effectively avoid sun exposure or wind and rain, extend the service life of the wires, and ensure that the monitoring device 30 works stably for a long time.

[0035] In another embodiment, see Figure 6 A tower crane monitoring system includes a tower crane 20, an auxiliary fixing device 10, a monitoring device 30, and a central monitor 40.
