Detailed Description of the Embodiments

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0023] Embodiment

[0024] See Figures 1 to 3As shown in the figure, an anti-collision component for a tower crane boom includes an anti-collision structure 2 provided on the side of the boom 1. In this embodiment, the boom is a conventional structure of the prior art and is only simply applied. During actual application, the anti-collision structure includes a connecting frame 21, an anti-collision seat 22, an anti-collision pressing plate 23, a buffer spring 24, and a touch switch 25. In this embodiment, both the connecting frame and the anti-collision seat are metal structures. During installation, the connecting frame is fixed to the side of the boom through a screw. The screw can be a conventional screw or a U-shaped screw, and its main function is to fix the connecting frame to the boom.

[0025] Moreover, the anti-collision seat is fixed to the connecting frame through a screw, and the anti-collision seat is parallel to the side of the boom. The anti-collision pressing plate is fixed to the side of the anti-collision seat away from the boom through a buffer spring. At the same time, the touch switch is arranged on the anti-collision seat, and the touch switch is connected to the tower crane cab through a data cable. During use, when the anti-collision pressing plate is impacted, it compresses the buffer spring and abuts against the touch switch. When the anti-collision pressing plate is impacted, it will compress the buffer spring and, after moving a certain distance, will abut against the touch switch, and the touch switch will send a signal to the cab. Specifically, the touch switch is connected to the control circuit board of the cab, which is convenient for the driver to judge and make control actions in a timely manner.

[0026] During actual application, an avoidance groove 3 is provided on the side of the connecting frame, and the side of the boom is inserted into the avoidance groove. By setting the avoidance groove, the stability and reliability of the installation with the boom can be improved, and the contact area with the boom can be increased.

[0027] Moreover, during actual application, in order to ensure the smooth movement of the anti-collision pressing plate, a guiding hole 4 is provided on the anti-collision seat, and a guiding column 5 is fixed to the back of the anti-collision pressing plate. The guiding column is inserted into the guiding hole. This can prevent the anti-collision pressing plate from shifting. During actual application, the surface of the anti-collision pressing plate is wrapped with a buffer cushion 7. The buffer cushion can be a rubber structure, or a leather or cloth structure, and its main function is to protect the anti-collision pressing plate.

[0028] At the same time, in order to ensure the overall strength, a reinforcing rib 6 is fixed between the connecting frame and the anti-collision seat through a screw.

[0029] The utility model has positive effects: The structure of the utility model is reasonably arranged. By setting the anti-collision structure on the side of the boom, it is beneficial to improve the anti-collision performance. At the same time, through the buffer spring and the touch switch, the buffer performance can be improved, and the touch switch can send the touch signal to the cab, which is convenient for the driver to judge and handle in a timely manner, is beneficial to improving the use stability, and has strong usability and good practicality.

For the non-standard structural components described in the specification, they can also be directly processed without any doubt based on the existing common technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt the conventional models in the existing technology. Therefore, no specific description will be made here.

[0031] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And these obvious changes or variations derived from the essence of the present invention still fall within the protection scope of the present invention.
