Description

Technical Field

[0001] The invention relates to an improvement of a hose wear reduction technology, belongs to the field of liquid cargo transportation, and in particular to a stern hose recovery and slag removal device. Background Art

[0002] After the liquid cargo transfer operation is completed, when the winch is performing the hose retracting operation, a stern hose friction reduction device will be installed in front of the winch. This device guides the hose released or retracted by the liquid cargo transfer winch and can reduce the friction loss between the hose and the ship's side, thereby effectively improving the use condition of the hose, extending its service life, and avoiding the occurrence of dangerous operation situations.

[0003] However, after the liquid cargo transfer winch completes its transfer operation, residual liquid cargo or air may still remain inside the hose. When the hose is retrieved, this residual liquid cargo or air increases the thickness of the hose wrapped around the liquid cargo transfer winch, causing friction between the hose and the deck. Furthermore, during the hose winch recovery operation, the generally long hoses take a long time to recycle, further exacerbating friction between the hose and the mounting base at the bottom of the liquid cargo transfer winch, increasing the risk of hose damage and, in severe cases, even causing damage. However, existing stern hose friction reduction devices only reduce friction during the hose's return to the winch, but fail to address the problem of the hose becoming thicker due to residual liquid cargo or air, which causes friction with the deck.

[0004] A Chinese patent application with application number CN202311083091.5 and application date August 28, 2023 discloses a hose friction reduction device, comprising a bracket, an upper roller and a lower roller; the bracket comprises a left wall, a bottom wall and a right wall connected vertically in sequence; the top of the right wall has a locking groove and a step structure; the upper roller comprises an upper central shaft and an upper roller outer surface wrapped around the outside of the upper central shaft, a butterfly nut is screwed on one end of the upper central shaft passing through the locking groove, and the other end of the upper central shaft is movably connected to the top of the left wall; the lower roller is fixedly connected to the left and right walls, first loosen the butterfly nut so that the upper central shaft can rotate upward to leave the locking groove, and the top of the device is connected to the outside world. After placing a hose at this connection point, the upper central shaft is rotated downward to connect to the locking groove, and then the butterfly nut is tightened to restrain the hose and confine the hose to the device; there is rolling friction between the outer surface of the hose and the roller, which greatly reduces the friction force, but the above solution does not solve the problem that residual liquid cargo or air causes the hose to become thicker and thus rub against the deck.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. In a stern hose recovery and slag discharge device according to the present invention, a plurality of longitudinal roller assemblies are symmetrically arranged on the left and right sides of the inner wall of a friction-reducing roller main body bracket, with all longitudinal roller assemblies on the same side being equidistantly spaced. A longitudinal roller top clamp fastener is mounted above each longitudinal roller assembly on the left and right sides of the inner wall of the friction-reducing roller main body bracket, and the longitudinal roller top clamp fastener is secured to the longitudinal roller assembly via the longitudinal roller top clamp. During operation, when the hose passes through the first and third transverse roller assemblies, the spring mechanism compresses the hose, squeezing the space within the hose to a greater extent within the elastic range, thereby discharging liquid or gas therein. When the hose passes through the second transverse roller assembly, the spacing between the second transverse roller assembly and the two rear longitudinal roller assemblies is adjusted according to the thickness of the hose, thereby further squeezing the hose. Based on the original design of a single set of fixed rollers, the optimized and improved design adopts a multiple set of spring-compression friction-reducing rollers, which can more effectively squeeze out residual gas and liquid cargo within the hose. In addition, the multiple rollers can mitigate the impact of the device on the hose under harsh working conditions, preventing the hose from being bent or twisted. Therefore, the present invention can discharge residual liquid cargo or air to reduce friction.

[0028] 2. In a stern hose recovery and slag removal device of the present invention, a concave pairing slide rail includes a mounting plate and a concave chute, a concave chute is provided on the side of the mounting plate, and a convex pairing slide rail includes a sliding plate and a convex block, a convex block is installed on the side of the sliding plate, and the convex block slides in cooperation with the concave chute, a locking bolt is provided on the sliding plate, and a pulley is provided on the side of the convex block, and the pulley slides in cooperation with the concave chute. When used, based on the original fixed inlet pipe design, an extension mechanism is optimized and added to adapt to various ship types. The position of the second transverse roller assembly is adjusted by moving the pulley in the concave chute, and the distance of the device's inlet pipe position is adjusted to match the inlet pipe position and bending radius of the hose. In addition, the extension mechanism has a retractable function while ensuring the optimized wear reduction effect. When not in operation, the extension mechanism's outer roller can be recycled. Therefore, the present invention is easy to retract and can be used with most hoses.

[0029] 3. The stern hose recovery and deslagging device of the present invention utilizes a removable and reconfigurable design, based on the existing welded installation method, to simplify the structure. The stern hose recovery and deslagging device can be hoisted integrally onto a mounting surface and secured with bolts, simplifying the device's connection and installation requirements and effectively reducing the workload of interface verification. Consequently, the device is easy to assemble and disassemble, and convenient to transport.

[0030] 4. In the present invention's stern hose recovery and slag removal device, the existing friction-reducing drum has an open top. To prevent the hose from slipping out or jumping out during violent hull shaking during operation, a fully enclosed drum structure has been designed. This not only limits the position but also serves as a guide. Therefore, the present invention is safe to use and can provide guidance for the hose. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] This design adapts to various ship stern dimensions to the greatest extent possible, reducing installation location requirements. The compression effect of the left and right spring structures effectively reduces excess space inside the hose. The rollers are rolling motion pairs, and the contact area and contact method on the anti-friction device reduce friction. At the same time, the combined action of multiple sets of longitudinal and transverse rollers effectively supports the components through which the hose passes. Similarly, it is also applicable to hoses of various diameters.

[0063] Example 1:

[0064] A stern hose recovery and slag discharge device, the stern hose recovery and slag discharge device includes a wear-reducing roller main body bracket 1, a longitudinal roller top clamping plate fastener 2, a longitudinal roller top clamping plate 3, a longitudinal roller assembly 4, a first transverse roller assembly A, a third transverse roller assembly B and an extension mechanism; a plurality of longitudinal roller assemblies 4 are symmetrically arranged on the left and right sides of the inner wall of the wear-reducing roller main body bracket 1, and all the longitudinal roller assemblies 4 on the same side are equidistantly distributed, and longitudinal roller top clamping plate fasteners 2 are installed above each longitudinal roller assembly 4 on the left and right sides of the inner wall of the wear-reducing roller main body bracket 1, and the longitudinal roller top clamping plate fasteners 2 and the longitudinal roller assembly 4 are fixed by the longitudinal roller top clamping plate 3; between two adjacent longitudinal roller assemblies 4 A first transverse roller assembly A and a third transverse roller assembly B are respectively provided, and the first transverse roller assembly A and the third transverse roller assembly B are staggered up and down, and a spring mechanism 13 is provided on the sides of the first transverse roller assembly A and the third transverse roller assembly B; an extension mechanism is provided on the outer wall of one end of the wear-reducing roller main body bracket 1, and the extension mechanism includes two concave pairing slides 8, two convex pairing slides 10 and a second transverse roller assembly 11, and the two concave pairing slides 8 are respectively provided on the two outer walls of the wear-reducing roller main body bracket 1, and each concave pairing slide 8 is slidably matched with one end of the corresponding convex pairing slide 10, and a second transverse roller assembly 11 is provided between the other ends of the two convex pairing slides 10.

[0065] During application: When collecting the tube, with the assistance of multiple longitudinal roller assemblies 4, the hose passes through the first transverse roller assembly A, the third transverse roller assembly B and the second transverse roller assembly 11 in sequence, thereby passing through the friction-reducing roller main body bracket 1, guiding the hose. When passing through the first transverse roller assembly A and the third transverse roller assembly B, since the spring mechanism 13 is preset with a clamping force, the hose is squeezed under the compression of the spring force, and the space inside the hose is squeezed to a greater extent within the elastic action range, thereby achieving the effect of discharging the liquid or gas inside it. When passing through the second transverse roller assembly 11, the distance between the second transverse roller assembly 11 and the two longitudinal roller assemblies 4 at the rear is adjusted according to the thickness of the hose for further squeezing.

It is penetrated and arranged in the positioning hole 115; the longitudinal roller top clamp fastener 2 includes a positioning plate 21, two ribs 22 and a bayonet 23.
