Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic hose hoists, and particularly relates to a boom step bracket of a ship hydraulic hose hoist. Background Art

[0002] The hydraulic hose hoist is used for loading and unloading oil on a ship, mainly for lifting the hose connecting the dock and the ship, and can be adjusted at any time according to different working conditions of the ship. The boom of the hydraulic hose hoist is generally provided with a boom bracket for stable support. The boom is mainly supported by the support blocks in the support grooves directly contacting the bottom of the boom. Since the bottom of the boom has an inclined bottom profile, some of the support blocks in the support grooves cannot contact the bottom of the boom, resulting in the failure of the support function of some support blocks, that is, the phenomenon of being lifted off, which brings potential safety hazards to the stability of the boom. Summary of the Invention

[0003] Object of the Invention: In order to overcome the deficiencies in the prior art, the utility model provides a boom step bracket of a ship hydraulic hose hoist. By independently lifting and lowering the support blocks in the support groove part, a stepped support structure adapted to the inclined bottom structure profile of the boom can be formed, preventing the support blocks from being lifted off, and improving the support effect on the boom.

[0004] Technical Solution: To achieve the above object, a boom step bracket of a ship hydraulic hose hoist of the utility model includes a bracket for supporting the boom of the hydraulic hose hoist. The bracket includes a frame body part and a support groove part provided at the top end of the frame body part. The inner bottom of the support groove part is provided with support blocks;

[0005] The number of the support blocks is multiple arranged side by side along the arm length direction of the boom. The support blocks are separated from the inner bottom of the support groove part, and each support block is arranged to be liftable and lowerable along the groove depth direction of the support groove part; when each support block independently rises to a state of abutting against the bottom of the boom, a stepped support structure for supporting the boom is formed.

[0006] Further, a lifting drive part corresponding to the support block is provided in the support groove part, and the lifting drive part drives the corresponding support block to lift and lower in the groove depth direction of the support groove part.

[0007] Further, a pressure sensor spring is provided on the support surface of the support block, and the pressure sensor spring is installed in the installation hole opened on the support surface of the support block;

[0008] When the support block does not support the boom, the pressure sensor spring extends out of the installation hole and is higher than the support surface of the support block;

[0009] When the support block rises to support the boom, the pressure sensor spring is pressed down by the boom due to the rise of the support block.

[0010] Further, within the same supporting block, the pressure sensor spring is interlocked with the lifting drive unit through an airborne system suspended by a hydraulic hose.

[0011] Further, the lifting drive unit is an electric guide rail vertically installed on the inner groove wall of the bracket part.

[0012] Further, side limiting blocks for laterally limiting the jib are provided on the inner groove wall of the bracket part. The side limiting blocks are located within the gaps between adjacent electric guide rails, such that the side limiting blocks and the supporting blocks are alternately distributed in the length direction of the jib.

[0013] Further, the supporting surface of the supporting block is an anti-slip structural surface formed by setting patterns.

[0014] Further, the supporting surface of the supporting block and the limiting surface of the side limiting block are respectively coated with wear-resistant coatings made of wear-resistant materials.

[0015] Beneficial effects: By independently lifting and designing the supporting blocks within the bracket part, the utility model can form a stepped supporting structure that adapts to the inclined bottom structural contour of the jib, enabling all the supporting blocks within the bracket part to participate in supporting the jib, thereby preventing the supporting blocks from being lifted off, improving the supporting effect on the jib, and ensuring the stability and safety of the jib. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 is a schematic diagram of the overall structure of the utility model;

[0017] Figure 2 is a schematic diagram of the structure of the bracket part and the components inside the groove. DETAILED DESCRIPTION OF THE INVENTION

[0018] The following further describes the utility model with reference to the accompanying drawings.

[0019] As Figure 1 shown, a jib stepped bracket for a marine hydraulic hose crane includes a bracket 2 for supporting the jib 1 of the hydraulic hose crane. The bracket 2 includes a bracket body part 3 and a bracket part 4 provided at the top of the bracket body part 3. A supporting block 5 is provided at the inner bottom of the bracket part 4. Since the bottom of the jib has an inclined bottom contour, some of the supporting blocks within the bracket cannot contact the bottom of the jib, resulting in the failure of the supporting function of some of the supporting blocks, that is, the phenomenon of being lifted off, posing a safety hazard to the stability of the jib.

[0020] To solve the above problems, as Figure 1 and Figure 2As shown in the figure, the number of the supporting blocks 5 is multiple, which are arranged side by side along the arm length direction of the boom 1. The supporting blocks 5 are separated from the inner groove bottom of the trough part 4, and each supporting block 5 is arranged to be liftable along the groove depth direction of the trough part 4. When each supporting block 5 independently rises to the state of abutting against the bottom of the boom 1, a stepped supporting structure for supporting the boom 1 is formed. By independently lifting and lowering the supporting blocks 5 in the trough part 4, the utility model can form a stepped supporting structure adapted to the inclined bottom structure profile of the boom 1, so that all the supporting blocks 5 in the trough part 4 can participate in the support of the boom 1, thereby preventing the supporting blocks 5 from being lifted off, improving the supporting effect on the boom, and ensuring the stability and safety of the boom 1.

[0021] As Figure 2 shown in the figure, a lifting driving part 6 corresponding to the supporting block 5 is arranged in the trough part 4, and the lifting driving part 6 drives the corresponding supporting block 5 to lift and lower in the groove depth direction of the trough part 4. A pressure sensor spring 7 is arranged on the supporting surface of the supporting block 5, and the pressure sensor spring 7 is installed in the installation hole 50 opened on the supporting surface of the supporting block 5. When the supporting block 5 is in the state of not supporting the boom 1, the pressure sensor spring 7 extends out of the installation hole 50 and is higher than the supporting surface of the supporting block 5. When the supporting block 5 rises to support the boom 1, the pressure sensor spring 7 is pressed down by the boom 1 due to the rise of the supporting block 5. In the same supporting block 5, the pressure sensor spring 7 is interlocked with the lifting driving part 6 through the on-board system of the hydraulic hose crane. During the execution of the supporting operation, the boom 1 first falls into the trough part 4, and then the on-board system of the hydraulic hose crane controls each lifting driving part 6 to start, thereby driving each supporting block 5 to rise. Through the compression of the pressure sensor spring 7, the actual pressure value of the pressure sensor spring 7 is compared with the in-place pressure value built in the on-board system. When the actual pressure value rises to be the same as the in-place pressure value, it indicates that the corresponding supporting block 5 has risen to the position of abutting against the bottom of the boom 1. At this time, the corresponding lifting driving part 6 stops, and the supporting block 5 supports the boom 1, realizing automatic control and improving efficiency.

[0022] In the utility model, as a preference, the lifting driving part 6 is an electric guide rail vertically installed on the inner groove wall of the trough part 4.

[0023] As Figure 1 shown in the figure, in order to perform side limit on the boom 1, side limit blocks 8 for performing side limit on the boom 1 are arranged on the inner groove wall of the trough part 4. The side limit blocks 8 are located in the gaps between adjacent electric guide rails, so that the side limit blocks 8 and the supporting blocks 5 are alternately distributed in the arm length direction of the boom 1, ensuring that the support and limit distribution of the boom 1 are more uniform.

[0024] For anti-slip, the bearing surface of the bearing block 5 is an anti-slip structural surface formed by setting patterns. At the same time, in order to reduce wear, the bearing surface of the bearing block 5 and the limiting surface of the side limiting block 8 are respectively coated with wear-resistant coatings made of wear-resistant materials, such as iron-based coatings.

[0025] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
