Description

Technical Field

[0001] The utility model relates to the technical field of cranes, and more specifically to a novel bridge crane. Background Art

[0002] A bridge crane is a type of lifting equipment used horizontally above workshops, warehouses, and material yards to lift and transport materials. It fully utilizes the space within the lifting environment to lift and transport materials, offering the advantage of being unobstructed by ground-based equipment. Traditional bridge cranes, due to their multiple hollow structures, make the lifting hooks susceptible to environmental influences. Furthermore, the existing bridge crane structure is relatively complex, which to some extent affects maintenance costs and operational effectiveness. To overcome these shortcomings, this proposal was developed. Utility Model Content

[0003] The purpose of this utility model is to provide a new type of bridge crane in order to solve the above technical problems.

[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0005] A new type of bridge crane includes a first bridge side frame, a second bridge side frame, and a lifting assembly. Independent drive devices for moving the bridge side frames are provided at the side ends of the first bridge side frame and the second bridge side frame. Guide rails for cooperating with the movement of the lifting assembly are provided at the top ends of the first bridge side frame and the second bridge side frame. The lifting assembly includes a base, a lifting moving wheel, a mobile servo motor, a rope drum, a transmission box, a lifting motor, a lifting frame, a rope drum, and a hook. Two rope drums are provided and arranged side by side. The lifting motor is connected to the side end of the rope drum through the transmission box. The base moves along the guide rail through the lifting moving wheel. The mobile servo motor is connected to the lifting moving wheel. One end of the rope drum is connected to the transmission box, and the other end is rotatably installed on the bearing frame. A lifting frame is provided at the bottom end of the base. The lifting frame adjusts the hoisting rope drum through a steel cable. Several rope drums are connected in a side-by-side combination through a frame, and the hook is locked and installed on the frame.

[0006] A better technical solution: a transition wheel is rotatably installed on the lifting frame.

[0007] A preferred technical solution: four independent drive devices are provided, each of which includes a drive servo motor and two guide wheels.

[0008] A preferred technical solution: The hook includes a threaded rod and a T-shaped hook rod, the threaded rod is locked and installed on the frame, and the T-shaped hook rod is threadedly connected to the threaded rod.

[0009] A better technical solution: the base is I-shaped.

[0010] A preferred technical solution: The vertical cross-sections of the first bridge side frame and the second bridge side frame are trapezoidal structures.

[0011] The beneficial effects of the utility model are as follows:

[0012] The bridge crane in the utility model has a large lifting weight and a more streamlined structure; the double lifting motors independently control the respective rope drums to effectively ensure lifting; the relative positions of the lifting components can be flexibly fine-tuned by moving the servo motor, and the structural coordination application effect is good.

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0022] like Figures 1 to 6 As shown, this embodiment provides a new type of bridge crane, including a first bridge side frame 1, a second bridge side frame 2, and a lifting assembly 3. The side ends of the first bridge side frame 1 and the second bridge side frame 2 are provided with independent driving devices 4 for moving the bridge side frames. The tops of the first bridge side frame 1 and the second bridge side frame 2 are provided with guide rails 5 for cooperating with the lifting assembly 3 to move. The lifting assembly 3 includes a base 31, a lifting moving wheel 32, a moving servo motor 33, a rope drum 34, a transmission box 35, a lifting motor 36, a lifting frame 37, a rope drum 38, and a hook 39. The rope drum 34 is provided with a lifting wheel 32, a moving servo motor 33, a rope drum 34, a transmission box 35, a lifting motor 36, a lifting frame 37, a rope drum 38, and a hook 39. Two are arranged side by side, the lifting motor 36 is connected to the side end of the rope drum 34 through the transmission box 35, the base 31 moves along the guide rail 5 through the lifting moving wheel 32, the mobile servo motor 33 is connected to the lifting moving wheel 32, one end of the rope drum 34 is connected to the transmission box 35, and the other end is rotatably installed on the bearing frame 310, and a lifting frame 37 is set at the bottom end of the base 31. The lifting frame 37 adjusts the lifting rope drum 38 through a steel cable. Several rope drums 38 are connected in a side-by-side combination through a frame, and the hook 39 is locked and installed on the frame.

[0023] The transmission box 35 includes a plurality of parallel shafts, on which gears are arranged. The gears on different shafts mesh with each other, and the size of the gears can be flexibly set according to needs to adjust the stability and efficiency of the meshing transmission.

[0024] Furthermore, a transition wheel 311 is rotatably mounted on the lifting frame 37 .

[0025] Furthermore, four independent driving devices 4 are provided, and each independent driving device 4 includes a driving servo motor 41 and two guide wheels 42 .

[0026] Furthermore, the hook 39 includes a threaded rod 391 and a T-shaped hook rod 392 . The threaded rod 391 is fixedly mounted on the frame, and the T-shaped hook rod 392 is threadedly connected to the threaded rod 391 .
