DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0037] Please refer to Figures 1-5In this embodiment of the utility model, a crane boom anti-collision device includes a cable winding structure 1, a monitoring structure 2, and an extension mounting frame 3. The cable winding structure 1 consists of two sets, each including a storage box 101. A winding shaft 103 is rotatably mounted inside the storage box 101, and the two winding shafts 103 are fixedly connected to both ends of a tripwire 107. The monitoring structure 2 is fixedly installed on one side of the storage box 101. The front end of the extension mounting frame 3 is fixedly connected to the rear surface of the storage box 101.

[0038] Specifically, multiple sets of integrated anti-collision devices are equipped and installed around the crane boom. The storage box 101 at one end of the tripwire 107 is fixedly installed at the base of the base rod through the extension mounting bracket 3, and the storage box 101 at the other end of the tripwire 107 is installed at the top of the telescopic rod. The boom is surrounded by several tripwires 107. The two ends of the tripwire 107 are wound and unwound using the winding shaft 103. The adaptive telescopic boom can change its actual length. The monitoring structure 2 monitors the force on the tripwire 107 in real time, thereby monitoring whether the boom touches any objects and providing real-time protection for the entire boom.

The return spring 105 is snapped into the inside of the spring housing 104, and the return spring 105 is fixedly connected to one end of the winding shaft 103.

[0041] In this embodiment, when the boom extends, the tripwire 107 is pulled out from the surface of the winding shaft 103. At the same time, the rotation of the winding shaft 103 drives the reset spring 105 to accumulate elastic potential energy. When the boom retracts, the reset spring 105 drives the winding shaft 103 to reset and rotate, thereby rewinding the excess tripwire 107 into the storage compartment 102, thus achieving adaptive adaptation to the actual length of the boom.

[0042] like Figure 1 , Figure 5 As shown, in this embodiment, the extended mounting bracket 3 includes a box mounting base 303, a tripod 302, and a mounting base 301.
