Specific implementation mode
[0024] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific implementation modes.
[0025] The slidable adjustable winch mounting mechanism of the present invention includes a fixed frame 1 located below the crane boom body. The fixed frame 1 is provided with a mounting hole for mounting the telescopic oil cylinder 2. The telescopic oil cylinder 2 is assembled with the fixed frame 1 through the cylinder barrel mounting shaft 7. The fixed frame 1 is provided with a sliding track for the telescopic frame assembly 3 to slide. The fixed frame 1 is provided with a mounting hole for mounting the fixed shaft 8. The telescopic frame assembly 3 includes a telescopic frame 31 and a slider 32. The slider 32 is connected to the telescopic frame 31 through a screw 33. The telescopic frame assembly 3 is assembled into the slideway of the fixed frame 1 and can slide along the slideway of the fixed frame 1. The telescopic oil cylinder 2 is assembled with the telescopic frame 31 through the cylinder rod mounting shaft 6. The telescopic frame 31 is provided with a mounting hole for the fixed shaft 8. The fixed frame 1 and the telescopic frame assembly 3 are fixedly assembled through the fixed shaft 8. A circlip 9 for preventing the shaft from falling off is assembled on the fixed shaft 8. The telescopic frame 31 is connected to the winch 4 through a second nut 34 and a second bolt 35.
[0026] The fixed frame 1 of the present invention is fixed below the crane boom body through a first bolt 10 and a first nut 11. One end of the sliding track of the fixed frame 1 is provided with a baffle 5 for preventing the telescopic frame assembly 3 from sliding out of the track. The fixed frame 1 is provided with a chute for assembling the telescopic frame assembly 3. The cylinder rod mounting shaft 6 is provided with a retaining ring for preventing the shaft from falling off. The cylinder barrel mounting shaft 7 is provided with a retaining ring for preventing the shaft from falling off. The telescopic frame 31 is provided with a mounting hole for mounting the telescopic oil cylinder 2. The telescopic frame 31 is provided with a mounting hole for mounting the fixed shaft 8. The telescopic frame 31 is provided with a handle for manual pushing and pulling.
[0027] The telescopic frame assembly 3 of the present invention slides and adjusts within the sliding track of the fixed frame 1, thereby realizing the sliding adjustment of the winch 4 and avoiding interference with the flying boom.
[0028] The crane of the present invention uses the above-mentioned slidable adjustable winch mounting mechanism.
[0029] The present invention has two working modes: oil cylinder power and manual power.
[0030] I. The components mainly included in the oil cylinder power scheme are a fixed frame 1, a telescopic oil cylinder 2, a telescopic frame assembly 3, a winch 4, a baffle 5, a cylinder rod mounting shaft 6 and a cylinder barrel mounting shaft 7.
[0031] II. The manual power solution mainly includes components such as a fixed frame 1, a telescopic frame assembly 3, a winch 4, a baffle 5, a fixed shaft 8 and a snap ring 9.
[0032] When the crane uses the hoisting winch for operation, the hoisting winch slides to the lower part of the boom body. When the fly boom folds and retracts to the vehicle, the hoisting winch slides outward from the boom body without interfering with the fly boom, enabling the fly boom to fold back completely.
[0033] The present invention provides a slidable and adjustable winch mounting mechanism. By using structures such as the slideway of the fixed frame and the sliding frame assembly, the hoisting winch can be slidably adjusted within a certain range. By controlling the sliding of the winch, while meeting the working requirements of the hoisting winch, interference with the fly boom is avoided, ensuring that the fly boom can fold back completely, solving the interference problem of simultaneously installing a fly boom and a hoisting winch on a folding boom truck crane, and enabling the driving height of the folding boom crane with a fly boom and a hoisting winch to meet the road requirements.
