Description

Technical Field

[0001] The utility model belongs to the technical field of electric single-rail cranes, and particularly relates to a material hoisting device for a ship-mounted electric single-rail crane. Background Art

[0002] Installing an electric single-rail crane on the top of the cabin of a ship can be used for the hoisting operation of cabin-stored goods to improve the cargo loading efficiency. The existing electric single-rail cranes generally use a support mechanism to limit the swing of the material hoist. Since it only realizes the limit in the vertical direction and lacks the limit function in the horizontal direction, during the walking process, the material hoist is prone to sway in the horizontal direction. Although the sway displacement is small, when transmitted to the hoisted goods, it will cause a large swing amplitude of the goods, reducing the stability of the goods hoisting. Summary of the Invention

[0004] Technical Solution: To achieve the above object, a material hoisting device for a ship-mounted electric single-rail crane of the utility model includes a walking frame and a material hoist. The material hoist is arranged on the walking frame loaded on the ship through a support mechanism and a walking mechanism;

[0005] The material hoist includes an anti-sway device. The support mechanism is located at the top of the material hoist, and the anti-sway device is located on the side of the material hoist. The support mechanism and the anti-sway device constitute a stable walking attitude system for the material hoist at the top and side double connection points.

[0006] Further, the anti-sway device includes a telescopic connecting rod part. Both ends of the telescopic connecting rod part have two welding connecting plates. Both ends of the telescopic connecting rod part are respectively connected to the material hoist and the guide rail on the ship through the two welding connecting plates.

[0007] Further, the telescopic connecting rod part is an adjustable pull rod, and both ends of the adjustable pull rod are pin-connected to the corresponding welding connecting plates.

[0008] Further, the material hoist includes a body; the welding connecting plate corresponding to the material hoist is welded to the body, the welding connecting plate corresponding to the ship is welded to the slider of the guide rail in the cabin, and the telescopic connecting rod part is perpendicular to the body.

[0010] Further, the walking frame is located on the main body; a hoisting mechanism is also provided on the main body, and head pulleys are respectively arranged at both ends of the main body. A steel wire rope led out from the hoisting mechanism is connected with a hook pulley through the head pulley.

[0011] Further, the material hoist has a maintenance platform connected to the main body, and the maintenance platform extends along the length direction of the main body.

[0012] Beneficial effects: The utility model laterally limits the material hoist through an anti-sway device and combines with a support mechanism to realize stable anti-sway in both vertical and horizontal directions of the material hoist, thereby avoiding lateral sway during the walking of the material hoist on the walking frame. The anti-sway stability is greatly improved, ensuring the stability and safety of the walking and hoisting operations, and being suitable for large-scale popularization and application.

[0016] The following further describes the present utility model with reference to the drawings.

[0017] As Figure 1 and Figure 2 shown, a material hoist device of a ship-mounted electric monorail crane includes a walking frame 3 and a material hoist 4. The material hoist 4 is arranged on the walking frame 3 loaded on a ship through a support mechanism 1 and a walking mechanism 2. This electric monorail crane uses the support mechanism to limit and anti-sway the material hoist. Since it only realizes the limit in the vertical direction and lacks the limit function in the horizontal direction, during the walking process, the material hoist is prone to lateral sway. Although the sway displacement is small, when it is transmitted to the hoisted goods, it will cause a large sway amplitude of the goods, reducing the stability of the goods hoisting.

[0018] To solve the above problems, in the present utility model, as Figure 1 and Figure 2As shown in the figure, the material hoist 4 includes an anti-sway device 5. The support mechanism 1 is located at the top of the material hoist 4, and the anti-sway device 5 is located on the side of the material hoist 4. The support mechanism 1 and the anti-sway device 5 constitute a stable walking attitude system for the material hoist 4 at the top and side double connection points. The utility model limits the material hoist 4 laterally through the anti-sway device 5 and combines with the support mechanism 1 to achieve stable anti-sway in the vertical and horizontal directions of the material hoist 4, thereby avoiding lateral shaking during the walking of the material hoist on the walking frame 3. The anti-sway stability is greatly improved, ensuring the stability and safety of the walking and hoisting operations, and being suitable for large-scale popularization and application.

[0019] As Figure 3 shown, the anti-sway device 5 includes a telescopic link part 51. The length of the anti-sway device 5 can be adjusted through the telescopic link part 51, which is convenient for its installation. Both ends of the telescopic link part 51 have two welding connecting plates 52. The two ends of the telescopic link part 51 are respectively connected to the material hoist 4 and the guide rail on the ship through the two welding connecting plates 52, and the guide rail is arranged in parallel with the walking frame 3.

[0020] As a preference, the telescopic link part 51 is an adjustable pull rod. The two ends of the adjustable pull rod are respectively pin-connected to the corresponding welding connecting plates 52, which is convenient for adjustment and installation.

[0021] As Figure 2 and Figure 3 shown, the material hoist 4 includes a body 6; the welding connecting plate 52 corresponding to the material hoist 4 is welded to the body 6, and the welding connecting plate 52 corresponding to the ship is welded to the slider of the guide rail in the cabin. Moreover, the telescopic link part 51 is perpendicular to the body 6, realizing the lateral limit of the material hoist, so as to have an anti-sway effect on the material hoist 4 in the horizontal direction.

[0022] In order to further improve the anti-sway effect and stability of the material hoist 4, the number of the support mechanisms 1 and the number of the anti-sway devices 5 are both one pair. This pair of support mechanisms 1 and this pair of anti-sway devices 5 are respectively arranged on the body 6 of the material hoist 4 in a counter-bracing manner with respect to the walking mechanism 2.

[0023] As Figure 1 shown, the walking frame 3 is located on the body 6; a hoisting mechanism 7 is further arranged on the body 6. Head pulleys 8 are respectively arranged at both ends of the body 6. The steel wire rope 9 led out from the hoisting mechanism 7 is connected to a hook pulley 10 through the head pulley 8. The material hoist 4 has a maintenance platform 11 connected to the body 6, and the maintenance platform 11 extends along the length structure direction of the body 6.

[0024] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
