Description

Technical Field

[0001] This utility model relates to the field of bridge crane trolley technology, and in particular to a bridge crane trolley mechanism. Background Technology

[0002] Existing bridge crane trolley mechanisms lift objects by connecting hooks or clamps with steel cables. However, this method can lead to instability of the center of gravity when lifting liquids due to inertia, thus affecting the safety of the lifting process. For example, a Chinese patent discloses a "bridge crane trolley traveling mechanism" with the application number "CN202320473613.1". This device uses a buffer shell, buffer strip, limit block, top plate, buffer block, spring and buffer head. When the trolley traveling mechanism stops at the end of the track, the contact buffer head can effectively play a buffering role. However, if the center of gravity is unstable when lifting objects, this device may pose a safety hazard. Utility Model Content

Detailed Implementation

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Reference Figure 1 , Figure 2 ,and Figure 3 This utility model discloses a bridge crane trolley mechanism, comprising: a main beam 3, a guide rail 23 mounted on the main beam 3, a base 1 mounted below the main beam 3, wheels 5 rotatably connected to the inner wall of the guide rail 23, a rotating shaft 6 fixedly connected to the side surface of the wheels 5, a carriage 4 rotatably connected to the outer surface of the rotating shaft 6, a support frame 19 fixedly connected inside the carriage 4, and two drums 20 and 21 rotatably connected to the upper surface of the support frame 19, with the outer surfaces of the two drums 20 and 21 being movably connected... A lifting steel cable 8 is connected to the lower end of the lifting steel cable 8. A fixing plate 14 is fixedly connected to the lower end of the fixing plate 14. A clamping plate 15 is slidably connected to the lower surface of the fixing plate 14. A fixing hole 24 is provided on the side surface of the clamping plate 15. A fixing shaft 16 is fixedly connected to the inner wall of the fixing hole 24. A hook 17 is fixedly connected to the outer surface of the fixing shaft 16. An auxiliary steel cable 9 is fixedly connected to the upper surface of the fixing plate 14. A drum 12 is movably connected to the upper end of the auxiliary steel cable 9. A fixing shaft 11 is rotatably connected to the side surface of the drum 12.

[0021] Specifically, when hoisting an object, the trolley moves to directly above the object via wheels 5, and rotates drums 20 and 31 to extend the lifting cables 8 wound on them, causing the fixed plate 14 to descend. Then, depending on the type of object to be hoisted, clamping plate 15 or hook 17 is selected for transport. When using clamping plate 15, the fixed shaft 216 is disassembled and the hook 17 is removed. According to the hoisting dimensions, clamping plate 15 is moved to a suitable position. When using hook 17, the hook 17 is installed on the fixed shaft 216 and clamped by clamping plate 15. After the object to be hoisted is secured, drums 20 and 31 are rotated to lift the object via the lifting cables 8. At the same time, during the lifting process, auxiliary cables 9 are tightened via drum 12 to prevent swaying during hoisting.

[0022] A support plate 13 is provided on the base 1. The support plate 13 is fixedly connected to the fixed shaft 11. A motor 10 is fixedly connected to the lower surface of the support plate 13. The output end of the motor 10 is fixedly connected to the drum 12.

[0023] Specifically, during the ascent of the object, the motor 13 drives the drum 12 to rotate, thereby tightening the auxiliary steel cable 9. At the same time, the drum 12 is fixed to the support plate 13 by the fixed shaft 11 to prevent the drum 12 from shaking during the movement.

[0024] A baffle 2 is fixedly connected to the upper surface of the main beam 3, a buffer block 7 is fixedly connected to the side surface of the carriage 4, a motor 2 18 is fixedly connected to the lower surface of the carriage 4, the output end of the motor 2 18 is fixedly connected to the rotating shaft 6, a motor 3 22 is fixedly connected to the inner wall of the carriage 4, and the output end of the motor 3 22 is fixedly connected to the drum 3 21 and the drum 2 20 respectively.

[0025] Specifically, before lifting the object, the second motor 18 drives the wheels 5 to move within the guide rail 23 on the main beam 3, moving the trolley to the appropriate position. The third motor 22 then lowers the lifting cables 8 on the drum 3 21 and the second drum 20. At the same time, baffles 2 are fixed at both ends of the main beam 3, and buffer blocks 7 are installed on the side surface of the carriage 4. When the trolley reaches the end position, the movement is restricted by the baffles 2. The buffer blocks 7 also prevent the trolley from directly hitting the baffles 2 and causing equipment damage.

[0026] Working principle: Before lifting the object, motor 218 drives the wheels 5 to move within the guide rails 23 on the main beam 3, moving the trolley to the appropriate position. Motor 32 then rotates drums 20 and 21, extending the lifting cable 8 wound around them and causing the fixed plate 14 to descend. Simultaneously, baffles 2 are fixed at both ends of the main beam 3, and buffer blocks 7 are installed on the side surfaces of the carriage 4. When the trolley reaches the end position, the movement is restricted by the baffles 2. The buffer blocks 7 also prevent the trolley from directly impacting the baffles 2 and causing equipment damage. Then, depending on the type of object to be lifted, clamps 15 or hooks 17 are selected for transport. When transporting the clamp plate 15, disassemble the second fixed shaft 16 and remove the hook 17. According to the lifting dimensions, move the clamp plate 15 to a suitable position. When transporting the hook 17, install the hook 17 on the second fixed shaft 16 and clamp the hook 17 with the clamp plate 15. After the object to be lifted is fixed, rotate the second drum 20 and the third drum 21 to lift the object by the lifting cable 8. At the same time, during the lifting process, the motor 13 drives the first drum 12 to rotate, thereby tightening the auxiliary cable 9. Meanwhile, the first drum 12 is fixed to the support plate 13 by the first fixed shaft 11 to prevent the first drum 12 from shaking during the movement.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
