Description

Technical Field

[0001] This utility model relates to the field of tower crane technology, and more specifically, to a tower crane with a tail fin. Background Technology

[0002] A tower crane is a type of crane used for vertical and horizontal material transport. The main structure of a tower crane consists of the following parts: base, tower body, slewing platform, operator's cab, counterweight boom, lifting boom, and hoisting mechanism. The tower body is a vertical steel structure, typically composed of multiple standard sections, and its height can be adjusted via bolt connections. The slewing platform is located at the top of the tower body, allowing the boom to rotate horizontally around the center of the tower body. The operator's cab is mounted on the slewing platform. The lifting boom is responsible for the actual lifting operations, and its working radius can be changed through a luffing mechanism. The counterweight boom is used to install counterweights to balance the torque generated by the lifting boom when lifting heavy objects. The hoisting mechanism, driven by a motor and a reducer, rotates the drum to wind or release the wire rope, thus lifting or lowering the goods. References to invention patent applications CN119160803A and CN118718620A disclose a tower crane structure.

[0003] The counterweights installed on the counterweight boom are rectangular in shape. This rectangular shape generates significant wind resistance, posing a safety hazard to the tower crane in windy weather and increasing the risk of the crane being blown over. Therefore, reducing the wind resistance of the counterweights and mitigating the safety risks of tower cranes affected by strong winds is a technical problem that urgently needs to be solved by those skilled in the art.

[0004] In addition, improving the functionality of tower cranes is another issue that needs to be addressed. Summary of the Invention

[0005] This utility model aims to solve the technical problem of how to reduce the wind resistance of the counterweight on the counterweight arm of a tower crane, reduce the safety hazards of tower cranes affected by strong winds, or realize the multifunctionality of tower cranes, and provides a tower crane with a tail fin.

[0006] This utility model provides a tower crane with a tail fin, including a counterweight arm connected to the counterweight arm, and a tail fin connected to the counterweight arm. The tail fin includes a first rectangular frame, a second rectangular frame, an arc-shaped frame, and a wire mesh. The first rectangular frame is fixedly connected to the counterweight arm, the second rectangular frame is fixedly connected to the counterweight arm, one end of the arc-shaped frame is connected to one end of the first rectangular frame, and the other end of the arc-shaped frame is connected to one end of the second rectangular frame. The first rectangular frame, the second rectangular frame, and the arc-shaped frame form an enclosure, and the wire mesh is connected to the enclosure. The tail fin surrounds the upper part of the counterweight arm.

[0007] Preferably, a flexible LED display screen is connected to the wire mesh.

[0008] This utility model also provides a tower crane with a tail fin, including a counterweight arm connected to the counterweight arm. The tail fin is characterized by being connected to a first rectangular frame, a second rectangular frame, an arc-shaped frame, and a flexible LED display screen. The first rectangular frame is fixedly connected to the counterweight arm, the second rectangular frame is fixedly connected to the counterweight arm, one end of the arc-shaped frame is connected to one end of the first rectangular frame, and the other end of the arc-shaped frame is connected to one end of the second rectangular frame. The first rectangular frame, the second rectangular frame, and the arc-shaped frame form an enclosure, and the flexible LED display screen is connected to the enclosure.

[0009] The beneficial effects of this invention are that the tail fin reduces wind resistance at the counterweight, thereby mitigating safety hazards to the tower crane caused by strong winds. It also increases the tower crane's functionality by incorporating a flexible LED display screen, which can display advertising information and warning messages.

[0010] Further features and aspects of this invention will be clearly described in the following detailed description with reference to the accompanying drawings. Attached Figure Description

[0023] The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The specific embodiments described below are merely preferred embodiments of this application, and the scope of protection of this application is not limited thereto. Those skilled in the art can make modifications or variations based on the principles, concepts, and spirit of this application, and the resulting technical solutions should all be covered within the scope of protection of this application.

[0025] This utility model discloses a tower crane with a tail fin, which is an improvement on the existing tower crane structure by adding a tail fin. The tail fin reduces the wind resistance of the counterweight and reduces the safety hazards of the tower crane being affected by strong winds.

[0026] like Figure 1-10 As shown, the tower crane with a tail fin includes a tower body, a slewing platform 2, an operator's cab, a counterweight boom 1, a lifting boom 3, a hoisting mechanism, etc. A counterweight block 4 is installed on the counterweight boom 1. The improvement of this utility model is that a tail fin 5 is installed on the counterweight boom 1, and the tail fin 5 surrounds the upper part of the counterweight block 4. The tail fin 5 includes a first rectangular frame 5-1, a second rectangular frame 5-2, an arc-shaped frame 5-3, and a wire mesh 5-4. The first rectangular frame 5-1 is fixedly connected to the counterweight boom 1 through triangular brackets 6 and 7. The second rectangular frame 5-2 is also fixedly connected to the counterweight boom 1 through two triangular brackets. One end of the arc-shaped frame 5-3 is connected to one end of the first rectangular frame 5-1, and the other end of the arc-shaped frame 5-3 is connected to one end of the second rectangular frame 5-2. The first rectangular frame 5-1, the second rectangular frame 5-2, and the arc-shaped frame 5-3 form an enclosure that surrounds the upper part of the counterweight block 4, with the arc-shaped frame 5-3 located on the outermost side. The wire mesh 5-4 is connected to the enclosure (i.e., the wire mesh is connected to the upper part of the first rectangular frame 5-1, the second rectangular frame 5-2, and the arc-shaped frame 5-3), and the wire mesh 5-4 is arranged throughout the enclosure. Considering the characteristics of the counterweight, the entire tail fin 5 can reduce wind resistance, thereby reducing the safety hazards of the tower crane being affected by strong winds.

[0027] Further improvements include installing a flexible LED display screen on the tail fin, specifically on the wire mesh 5-4. This flexible LED display screen can display advertising information, thus achieving a more versatile functionality. It can also display warning messages to remind on-site personnel to pay attention to safe operating procedures.

[0028] It should be noted that a flexible LED display screen can be used instead of wire mesh, meaning that the entire surface of tail fin 5 is an LED display screen.
