Abstract
Description
Technical Field
[0001] The utility model belongs to the field of hydraulic metal structures, in particular to an anti-collision device with hydraulic cylinder buffer. Background Art
[0002] With the development of water transportation, vertical ship lifts have gained widespread application as efficient and convenient navigation facilities. In vertical ship lifts, ships are moved vertically between upstream and downstream via a ship carrier. However, due to the limited space within the carrier, when a large number of ships or a single large vessel enters the carrier, improper operation or other factors can easily lead to collisions between the ships and the carrier, resulting in significant impact forces. This impact can not only damage the carrier structure but also affect the safety and stability of the vessel, potentially causing casualties.
[0003] To address these issues, existing technologies offer some anti-collision measures, such as simple rubber cushions. However, these methods often prove inadequate in the face of significant impact forces and fail to effectively protect the vessel and lift structure from damage. Therefore, a more effective anti-collision buffering device is needed that can provide reliable protection against impacts of varying magnitudes while ensuring the safety of the vessel and equipment. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to provide an anti-collision device with a hydraulic cylinder buffer, which has a simple structure and is easy to operate and use, absorbs the energy of the collision to a great extent and increases safety.
[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0006] An anti-collision device with hydraulic cylinder buffering includes an anti-collision beam, track supports are provided at both ends of the anti-collision beam, the track supports cooperate with track grooves, a buffer jack is arranged behind the anti-collision beam, and the buffer jack is connected to the jack back bracket.
[0007] Preferably, an anti-collision buffer pad is provided on the anti-collision beam.
[0008] Preferably, the anti-collision beam is welded from a steel structure into a beam body.
[0009] Preferably, the rail support is a support body made of MGD and fastened to the anti-collision beam with bolts.
[0010] Preferably, the track groove is mainly cast with steel structure or concrete, and the track groove is used to provide guidance for the up and down movement of the anti-collision beam.
[0011] Preferably, the jack back support is a steel structure connected to the main concrete or steel structure as a whole, mainly to provide support reaction force for the buffer jack;
[0012] Preferably, the jack buffer guide rail is a steel structure between the anti-collision beam and the buffer jack, mainly providing guidance for the extension and retraction of the buffer jack.
[0013] The utility model can achieve the following beneficial effects:
[0014] 1. It can effectively absorb and disperse the impact force generated when the ship enters and exits the ship lift, ensuring the safe and stable vertical movement of the ship.
[0015] 2. When the impact force is small and the elastic deformation of the anti-collision beam has not yet reached its limit, the buffer jack mainly acts as a rigid support, and the impact energy is mainly converted into elastic deformation energy of the anti-collision beam. When the impact force exceeds a certain threshold, the buffer jack activates and, through the adjustment of the hydraulic system, converts the excess kinetic energy into heat energy, thereby effectively buffering the large impact force.

[0020] In a vertical ship lift, ships are carried vertically up and down the ship compartment by the ship carriage. Due to the limited space in the ship compartment, a large number of ships or a single large ship entering the ship compartment will cause impact on the compartment. In order to minimize this impact and ensure the stability of the ship during vertical movement, a special anti-collision buffer device is required to absorb the impact energy. Therefore, an anti-collision device with a hydraulic cylinder buffer is used here. The main function of this device is to stop the out-of-control ship and prevent the ship from directly hitting the ship compartment door:
[0021] The preferred solution is Figures 1 to 3As shown, an anti-collision device with hydraulic cylinder buffering includes an anti-collision beam 1, an anti-collision buffer pad 2, a track support 3, a track groove 4, a buffer jack 5, a jack back bracket 6, and a jack buffer guide rail 7. The anti-collision beam 1 is welded from a steel structure into a beam body, which directly bears the main impact load during operation; the anti-collision buffer pad 2 is made of engineering plastic and is in direct contact with the impact object during operation; the track support 3 is made of MGD or similar wear-resistant, high-hardness, and good-toughness materials, and is fastened to the anti-collision beam with bolts; the track groove 4 is mainly cast with steel structure or concrete, and provides guidance for the up and down movement of the anti-collision beam 1; the buffer jack 5 is arranged on the back of the anti-collision beam 1; the jack back bracket 6 is a steel structure connected to the main concrete or steel structure into one body, mainly providing support reaction force for the buffer jack 5; the jack buffer guide rail 7 is a steel structure between the anti-collision beam 1 and the buffer jack 5, mainly providing guidance for the expansion and contraction of the buffer jack 5.
[0022] The working principle of this device:
[0023] like Figure 1-3 As shown, the anti-collision device uses a combination of elastic steel beams and buffer jacks to absorb energy. The anti-collision beam has an I-shaped cross-section, on which are placed buffer rubber blocks and guide sliders. The buffer device consists of buffer sliders and buffer energy-absorbing cylinders. The buffer energy-absorbing cylinders are symmetrically arranged below the cabin walkway along the direction of water flow, with the front end of the piston rod connected to the buffer slider.
[0024] The fulcrum reaction force corresponding to the maximum allowable elastic deformation of the anti-collision beam is set as the operating pressure of the buffer jack. When the ship's impact kinetic energy is small, the elastic deformation of the anti-collision beam does not reach the maximum allowable value. The buffer jack only serves as a rigid support for the anti-collision beam, and all kinetic energy is converted into the elastic deformation energy of the anti-collision beam. When the ship's impact kinetic energy is large, after the elastic deformation of the anti-collision beam reaches the maximum allowable value, the buffer jack pressure reaches the set pressure of the hydraulic control system's relief valve, the relief valve opens and overflows, the cylinder piston rod retreats, and the ship's kinetic energy is converted into heat energy. In other words, the ship's kinetic energy is shared by the elastic deformation energy of the anti-collision beam and the work done by the cylinder resistance. When subjected to the ship's maximum impact kinetic energy, the buffer jack displacement reaches its maximum buffer stroke.
[0025] After the anti-collision beam is hit, the buffer device can be reset through the hydraulic system without affecting the ship's exit.

The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
