[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Example 1

[0034] This embodiment provides an unmanned ship unloading machine, such as Figures 1-4 As shown, the unmanned ship unloader includes an unmanned ship unloader bridge 1 and a unloading clamp 2. The lifting end of the unmanned ship unloader bridge 1 is connected to the unloading clamp 2 through a detachable mechanism 3.

[0035] The detachable mechanism 3 includes a clamp connecting seat 31 located below and a bridge connecting seat 32 located above, near or away from the clamp connecting seat 31. A first flange 311 is fixedly installed at the bottom of the clamp connecting seat 31, and a welding head 3111 for welding with different unloading clamps 2 is fixedly connected at the bottom of the first flange 311. A second flange 321 for welding with the lifting end of the bridge 1 of the unmanned ship unloader is fixedly installed at the top of the bridge connecting seat 32.

[0036] Four limiting slide rods 34 are fixedly connected to the bottom four corners of the cable tray connecting seat 32, passing through the clamp connecting seat 31 and slidingly connected to the clamp connecting seat 31. Each limiting slide rod 34 is fitted with a buffer spring 35 at both ends, which is connected to the clamp connecting seat 31 and the cable tray connecting seat 32 respectively.

[0037] In use, align the connecting part of the unloading clamp 2 with the welding head 3111 at the bottom of the clamp connecting seat 31 and weld it in place. At the same time, install and fix the bridge connecting seat 32 to the lifting end of the bridge via the second flange 321, thus completing the installation of the clamp. When the clamp is lifted and moved, the bridge connecting seat 32 is moved downward by the limiting slide rod 34. The limiting slide rod 34 slides in the clamp connecting seat 31, and the buffer spring 35 is compressed to generate damping, which can buffer the impact of inertia. The detachable structure 3 can be disassembled by simply removing the two flanges to separate the unloading clamp 2 and the unmanned ship unloader bridge 1.

[0038] Specifically, the clamp connecting seat 31 has at least six first fixing pins 312 arranged in a ring array, each of the first fixing pins 312 is screwed with a first lock nut 313 in contact with the bottom end of the first flange plate 311, the top end of the bridge connecting seat 32 has at least six second fixing pins 322 arranged in a ring array, each of the second fixing pins 322 is screwed with a second nut 323 in contact with the top end of the second flange plate 321; through the cooperation of the first fixing pin 312 and the first lock nut 313, and the cooperation of the second fixing pin 322 and the second nut 323, the first flange plate 311 can be fixed on the clamp connecting seat 31, and the second flange plate 321 can be fixed on the bridge connecting seat 32, thereby ensuring the stability and reliability of the connection between the hoisting end of the unloader bridge 1 and the unloading clamp 2, and ensuring that there is no loosening or falling during the unloading operation. This bolt and nut connection method is simple to operate and convenient to adjust and fix during installation and disassembly. When the unloading clamp 2 needs to be replaced or the detachable mechanism 3 needs to be maintained, the relevant parts can be quickly disassembled and reinstalled.

[0039] It should be noted that the bottom end of the limiting slide rod 34 has a limiting block for preventing the clamp connecting seat 31 from being separated; the limiting block can effectively prevent the clamp connecting seat 31 from being separated from the limiting slide rod 34, avoid safety accidents caused by accidental falling of the clamp connecting seat 31, and protect the safety of operators and equipment.

[0040] Embodiment 2

[0041] Different from embodiment 1, when the clamp is replaced, because the heights of different clamps are different, in order to ensure the operation accuracy of the clamp, the parameters of the unmanned operation system need to be adjusted, which is more troublesome and affects the efficiency. Moreover, the hoisting structure under the sun may be stretched due to the strain of the structural material, resulting in deviation from the fixed parameters and reducing the precision of the clamp clamping. Therefore, the four sides of the clamp connecting seat 31 and the bridge connecting seat 32 are fixedly provided with a tensioning assembly 33 for moving the clamp connecting seat 31 close to the bridge connecting seat 32.

[0042] Specifically, the tensioning assembly 33 includes a fixed frame 331 fixedly installed on the four sides of the bridge connecting seat 32, a winding wheel 332 rotationally connected to the side of the fixed frame 331 away from the bridge connecting seat 32, a motor 333 fixedly installed on the bridge connecting seat 32 and having an output end connected to the winding wheel 332, a movable wheel 334 rotationally connected to the four sides of the clamp connecting seat 31 and located below the corresponding winding wheel 332, and a steel wire rope 336 sleeved outside the movable wheel 334 and the winding wheel 332. One end of the steel wire rope 336 is fixedly installed on the winding wheel 332, and the other end is fixedly installed on the fixed frame 331.

[0043] In use, when the relative positions of the clamp connecting seat 31 and the bridge connecting seat 32 need to be adjusted, the motor 333 is started, if the clamp connecting seat 31 needs to be close to the bridge connecting seat 32, the motor 333 is rotated in the forward direction, the winding wheel 332 winds the steel wire rope 336, the steel wire rope 336 pulls the movable wheel 334 to move upward, and drives the clamp connecting seat 31 to move upward to close to the bridge connecting seat 32; if the clamp connecting seat 31 needs to be away from the bridge connecting seat 32, the motor 333 is reversed, the winding wheel 332 unwinds the steel wire rope 336, under the action of the gravity of the clamp connecting seat 31 and other possible external forces, the movable wheel 334 moves downward, and the clamp connecting seat 31 moves downward to be away from the bridge connecting seat 32.

[0044] Further, the fixed frame 331 is provided with a buffer structure 335 for avoiding the breakage of the steel wire rope 336, the buffer structure 335 comprises two reversing wheels 3351 rotatably connected to the fixed frame 331 and a buffer wheel 3352 rotatably arranged on the fixed frame 331 and moving close to or away from the reversing wheels 3351, the middle section of the steel wire rope 336 is alternately wound around the two reversing wheels 3351 and the buffer wheel 3352, wherein the fixed frame 331 is slidably connected with a sliding seat 3353 rotatably connected with the buffer wheel 3352, the fixed frame 331 has two ends fixedly connected with the fixed frame 331 and the sliding seat 3353 for pushing the buffer wheel 3352 away from the reversing wheels 3351, and a compression spring 3354 is arranged on the fixed frame 331; in normal working condition, the steel wire rope 336 is in a certain tension state, the compression spring 3354 pushes the buffer wheel 3352 away from the reversing wheels 3351, and the normal transmission of the steel wire rope 336 is ensured, when an abnormal situation occurs, such as the sudden shaking of the hoisted heavy object or the excessive external force acting on the steel wire rope 336, the tension of the steel wire rope 336 is sharply increased, the buffer wheel 3352 moves to the reversing wheels 3351 against the elastic force of the compression spring 3354, the compression spring 3354 is compressed, and part of the energy is absorbed, so that the breakage of the steel wire rope 336 due to excessive tension is avoided.

[0045] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical solution and concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
