[0002] There are two sets of anti-collision devices for a certain ship lift, located at the upstream and downstream ends of the cabin, and arranged anti-symmetrically on the inside of the cabin door to block the stalled ship and prevent the ship from damaging the cabin door and causing an accident. The anti-collision device mainly consists of a wire rope assembly, a truss structure, a truss locking device, a truss opening and closing device, a buffer cylinder, a wire rope guide pulley, a brake device, a load limit and guide device, a latch device, a latch device guide frame, and a drainage system in the engine room.

[0003] The anti-collision device adopts a layout scheme in which a buffer cylinder is connected to a steel wire rope and lifted by a truss. Specifically, the truss spans the cabin on top of the steel wire rope. Driven by the cylinder, one end of the truss can rotate 90° around the hinge point on one side of the cabin. One end of the steel wire rope is connected to the other end of the truss, and the other end of the steel wire rope is connected to the buffer cylinder through the steering pulley on the main longitudinal beam of the cabin. The truss rotates to a vertical or horizontal state to lift or lower the steel wire rope. Since there is currently no horizontal passage between the left and right bank decks of the cabin, personnel need to pass through the cabin's negative second-floor trestle to reach the left and right bank decks of the cabin. Large items cannot be transported, which seriously affects work efficiency and poses a safety risk. Utility Model Content

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Example 1

[0035] like Figure 1-Figure 3 As shown, this embodiment proposes a dual-purpose truss structure for a ship lift cabin, including a truss 4, one end of the truss 4 is connected to a transition frame 6, the inner end of the transition frame 6 is fixedly connected to the truss 4, and the outer end of the transition frame 6 is connected to an oblique connecting seat 7; the inner end of the oblique connecting seat 7 is fixedly connected to the transition frame 6, and the outer end of the oblique connecting seat 7 is inclined toward the top surface of the truss 4.

[0036] The outer end of the oblique connection seat 7 is connected to a first articulated seat 1, and the first articulated seat 1 is used to connect with a hydraulic opening and closing device, and the hydraulic opening and closing device is a hydraulic lifting cylinder. The hydraulic opening and closing device is connected to the side of the main longitudinal beam of the cabin. The first articulated seat 1 is connected to the piston rod of the hydraulic lifting cylinder.

[0037] The bottom surface of the transition frame 6 is connected with a second hinge seat 2, and the second hinge seat 2 is used to be directly connected to the side surface of the main longitudinal beam of the cabin.

[0038] When the piston rod of the hydraulic lifting cylinder extends upward, the transition frame 6 and the truss 4 rotate together in the vertical plane around the hinge point on the second articulated seat 2, and the transition frame 6 and the truss 4 gradually rotate from a vertical state to a horizontal state. On the contrary, when the piston rod of the hydraulic lifting cylinder contracts downward, the transition frame 6 and the truss 4 rotate together in the vertical plane around the hinge point on the second articulated seat 2, and the transition frame 6 and the truss 4 gradually rotate from a horizontal state to a vertical state.

[0039] The other end of the truss 4 is connected to a latch 5, one end of a steel wire rope is connected to the latch 5, and the latch 5 is used to control the connection or separation of the steel wire rope with the truss 4, and the other end of the steel wire rope is connected to the piston rod of the buffer cylinder through the steering pulley on the main longitudinal beam of the cabin. In this embodiment, the latch 5 is a hydraulic lock.

[0040] The truss 4 can lift and lower the wire rope. When passing a ship, the wire rope needs to make way, so the truss 4 is lowered, the wire rope clamp is fixed to the latch 5, and the wire rope is lifted by the truss 4. When blocking a ship, the wire rope is lowered by the truss 4, and then the wire rope clamp is fixed to the ship compartment, and the truss 4 is lifted up alone, leaving the wire rope for collision prevention.

[0041] A channel is installed on the top surface of the truss 4 , and the channel includes a grid passage 8 located on the bottom surface. The grid passage 8 is fixedly laid on the top surface of the truss 4 , and handrails 3 are arranged on both sides of the grid passage 8 .

[0042] The utility model sets the latch 5 at the end of the truss 4 for connecting or separating the anti-collision wire rope, so as to conveniently control the lifting and lowering of the wire rope; the utility model is installed on the top surface of the truss 4 so that it is convenient to go up and down, and there is a passage with handrails on both sides. After the passage is installed, the cables and oil pipes on the truss 4 are reasonably arranged without affecting the passage and convenient for subsequent maintenance. The positions of the hydraulic lifting cylinder and sensors at the end of the truss do not change. After the truss 4 is opened, the passage shall not interfere with the tower column wall. When the ship lift cabin goes up and down, the wire rope is tightened, and the truss 4 is in a horizontal state. Personnel can communicate with the cabin decks on the left and right banks through the grid aisle 8.

[0043] The utility model has a simple overall structure and is very convenient to install and use; it is suitable for various application scenarios; and the addition of a multifunctional grid channel allows for repeated use.

[0044] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
