Description

Technical Field

[0001] The present invention relates to the technical field of dock equipment, and in particular to a dock ship collision buffer device and a use method thereof. Background Art

[0002] The ship collision buffer equipment at the dock is usually called fender system or fender material. It is a special device installed on the waterside of the dock, berth, dock or other port structures. Its core functions are: 1. Absorbing impact energy. When a ship is berthing, mooring or leaving the berth, it will inevitably come into contact or collide with the dock structure; 2. The main function of the fender system is to absorb and dissipate the huge kinetic energy generated by these impacts; 3. Protect the ship and prevent the hull, superstructure, propeller, rudder and other parts of the ship from being damaged in the collision; 4. Protect the dock structure and prevent the dock wall, pile foundation, panel, bollard and other structures from being damaged or deformed due to ship collision; 5. Assist the ship's berthing operation, provide a certain resilience, and help the ship to position and stabilize when berthing.

[0003] After searching, the existing Chinese patent with publication number CN202510233942.2 discloses a ship collision buffer device. The buffer mechanism can effectively absorb and disperse collision energy, reduce the impact force of the ship during collision, and thus effectively reduce the damage to the ship. The two main columns are driven by the cylinder to move in the operating compartment. The two main columns will simultaneously drive the flipping mechanism and the pushing mechanism to work. The flipping mechanism can realize the change of the position of the buffer mechanism, so that during daily maintenance, maintenance personnel can quickly and efficiently complete the inspection, maintenance and replacement of the device, greatly reducing maintenance costs and time. The pushing mechanism can enhance the stability of the positioning plate during work and ensure the stability of the buffer mechanism during work.

[0004] The above technical solution has the following defects: although such dock ship collision buffer equipment can change the position of the buffer mechanism through the cylinder mechanism and the pushing mechanism adjustment device, the buffer mechanism is subjected to a large impact during actual use, which puts a great burden on the toothed pushing component and the supporting component, affecting the overall service life of the device, and the buffer mechanism cannot be used during inspection and maintenance. In order to ensure the intensity of use of the buffer equipment, facilitate inspection and replacement, and ensure the buffering function of the dock during replacement, a dock ship collision buffer equipment and a method of use thereof are proposed. Through modular buffer units and ground maintenance paths, low-maintenance transmission, and precise positioning innovative design, the maintenance logic of the dock anti-collision equipment is completely reconstructed, and the traditional "stop-ship and dismantling overhaul" is transformed into "change-and-go quick repair", which significantly improves the continuity and economy of dock operations.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and combines theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Summary of the Invention

[0007] The present invention provides a dock ship collision buffer device and a method for using the same, which solves the problem that traditional dock fender maintenance requires high-altitude operations or ship cooperation, poses safety risks and affects waterway operations.

[0008] The present invention solves the above-mentioned technical problems with the following solution: a dock ship collision buffer device, comprising an equipment box, a double-arm equipment mounting frame, a mounting frame, an independent buffer unit, and an annular pulley track. The equipment box and the annular pulley track are both pre-buried and installed in the dock. The equipment box is provided with an electric rotation assembly for the mounting frame, a hydraulic diagonal brace assembly, and an expandable positioning assembly. The double-arm equipment mounting frame can be rotatably mounted on the equipment box, the mounting frame is provided on the double-arm equipment mounting frame, and the independent buffer unit can be detachably mounted on the mounting frame.

[0009] The usage includes the following steps:

[0010] S1, core components installation and drive system integration, the equipment box and double-arm equipment placement rack, independent buffer unit are installed and transported to the dock for assembly;

[0011] S2, equipment box and track installation, the equipment box and the ring pulley track are installed in the concrete structure of the wharf;

[0012] S3, buffer unit and frame deployment, the fixed buffer unit can be quickly disassembled and assembled on the double-arm equipment placement frame through bolts;

[0013] S4, hydraulic and positioning system debugging, the hydraulic diagonal support assembly adsorbs the arm of the double-arm equipment placement frame, and the auxiliary arm and the fixed buffer unit loaded are bent to the dock so that the staff can disassemble and maintain it at the dock;

[0014] S5, system linkage and operation test, to detect whether there is rotation jamming, whether the positioning is stable and the energy absorption effect.

[0015] On the basis of the above technical solution, the present invention can also be improved as follows.

[0016] Furthermore, the equipment box is evenly provided with embedded parts, and the equipment box is provided with an inspection door. The embedded parts disperse the ship collision stress and prevent the equipment box from shifting, so that the internal drive system can be inspected without destroying the structure.

[0017] Furthermore, limiting pulleys are provided at both ends of the double-arm equipment mounting frame corresponding to the annular pulley track. The double-arm equipment mounting frame includes an adjusting disc, a bendable mounting arm, a built-in limiting cylinder, and a receiving bevel gear. The equipment box is provided with a mounting hole corresponding to the built-in limiting cylinder. The built-in limiting cylinder is provided with a pulley and a sealed bearing. The inner wall of the mounting hole is rotatably connected to the built-in limiting cylinder through the pulley and the sealed bearing. The limiting pulley prevents rotational deviation and ensures that the buffer unit is aligned with the collision point of the ship. The pulley + sealed bearing combination reduces friction loss, is waterproof and dustproof, and extends service life. The annular pulley track can be provided with a leakage hole to prevent water accumulation.

[0018] Furthermore, the adjustment disc and the bendable placement arm are rotationally connected through a rotating shaft, and the adjustment disc and the bendable placement arm are both provided with ear tubes. The ear tubes on both sides can be connected by bolts to ensure that the adjustment disc and the bendable placement arm are upright. The bolt connection realizes flexible conversion between "working upright state" and "maintenance bent state". After locking, the load-bearing capacity of the arm is enhanced, the anti-collision stability of the buffer unit is ensured, and it can be screwed into the bottom placement position.

[0019] Furthermore, the placement frame is provided with a card slot and a U-shaped hole corresponding to the independent buffer unit, the independent buffer unit is provided with an auxiliary pulley, the double-arm equipment placement frame is provided with a pulley groove corresponding to the auxiliary pulley, and the double-arm equipment placement frame is provided with a positioning card slot corresponding to the deployable positioning assembly. The independent buffer unit includes a fender, a buffer column, and a placement base plate. The modular design allows a single group of buffer units to be independently repaired or replaced, reducing downtime, and the auxiliary pulley simplifies the installation process.

[0020] Furthermore, the electric rotation assembly of the mounting frame includes a drive motor, a reducer, and a drive bevel gear. The drive bevel gear is rotationally connected to the equipment box through an annular bearing base. The bevel gears are engaged to achieve power steering, adapt to the spatial layout of the equipment box, and the reducer adjusts the speed and torque to avoid rotation overload and jamming.

[0021] Furthermore, the driving end of the driving motor is transmission-connected to the driving bevel gear through a reducer, and the driving bevel gear is meshingly transmission-connected to the receiving bevel gear.

[0022] Furthermore, the hydraulic diagonal brace assembly includes a diagonal brace hydraulic cylinder group and an auxiliary diagonal brace plate. The diagonal brace hydraulic cylinder group drives the auxiliary diagonal brace plate to rotate at the equipment box. The auxiliary diagonal brace plate is provided with an electromagnet, and the corresponding electromagnet is equipped with an iron plate set on the bendable placement arm. The hydraulic drive smoothly lowers the arm to the dock plane to avoid the risk of manual high-altitude operations. The magnet provides non-contact fixation and quick response.

[0023] Furthermore, the expandable positioning assembly includes a hydraulic base, a diagonal support hydraulic cylinder, and an expandable positioning frame. The hydraulic base is arranged in an equipment box, and the diagonal support hydraulic cylinder is arranged in the hydraulic base. The diagonal support hydraulic cylinder drives the expandable positioning frame to rotate and open and close in the equipment box. The positioning frame and the card slot form a rigid support to resist lateral impact during ship collision. The hydraulic system can be remotely controlled to open and close to adapt to different working conditions.

[0024] The beneficial effects of the present invention are as follows: the present invention provides a dock ship collision buffer device and a method of using the same, which has the following advantages:

[0025] 1. It solves the problem that traditional dock fender maintenance requires high-altitude operations or the cooperation of ships, which poses safety risks and affects waterway operations. The hydraulic diagonal support assembly drives the auxiliary diagonal support plate to absorb the arm frame, and the bendable placement arm is smoothly lowered to the dock surface. Maintenance personnel can operate directly on the dock ground, completely avoiding the danger of high-altitude operations;

[0026] 2. It solves the problem of traditional collision buffer equipment requiring complete disassembly and long downtime when damaged. When a unit is damaged, it can be replaced individually by simply removing the bolts, without the need to hoist the entire frame. The installation of a pulley guide system can effectively improve installation accuracy, and disassembly and maintenance can be carried out on the flat ground of the dock. During disassembly and maintenance, another set of buffer units can be used instead, without the need to stop the terminal operation for a long time.

[0027] 3. The buffer unit installation relies on hoisting, which can easily deviate and cause seal failure or uneven force. Maintenance personnel can operate directly on the dock floor, and core components such as the drive motor and hydraulic valve group can be directly maintained through the inspection door without destroying the dock structure.

[0028] 4. This type of dock ship collision buffer equipment completely reconstructs the maintenance logic of dock anti-collision equipment through modular buffer units, ground-based maintenance paths, low-maintenance transmission, and precise positioning innovative design, transforming the traditional "stop-and-go overhaul" into "change-and-go quick repair", significantly improving the continuity and economy of dock operations.
