Description

Technical Field

[0001] This invention belongs to the field of underwater equipment technology, specifically relating to a top-mounted double-layer load release device. Background Technology

[0002] An underwater load-release device is a specialized apparatus for loading and releasing loads in aquatic environments. Currently available load-release equipment primarily handles single loads and suffers from the following problems:

[0003] (1) Complex actuation mechanisms. The actuation mechanisms they use typically consist of multiple complex components, requiring precise control and adjustment to ensure that the load can be correctly loaded and released. These complex actuation mechanisms not only increase the manufacturing cost of the device, but also increase the complexity of operation and the risk of failure.

[0004] (2) Large space occupation and low space utilization. Existing loading and releasing devices are subject to certain limitations in terms of space occupation. Since loading and releasing devices usually need to be installed on underwater equipment or other carriers, their size and weight must be adapted to the limited space of the equipment. However, due to the complexity of the actuation mechanism, existing loading and releasing devices are often quite large, resulting in a large space occupation, which limits the number of loads that can be carried and the design and layout of the device itself.

[0005] (3) High requirements for loading posture and accuracy. During the loading process, it is necessary to ensure the correct alignment and stability between the load and the equipment to guarantee the normal operation of the equipment and the accuracy of release. However, due to the complexity of the actuating mechanism and the influence of limited space, existing loading and release equipment often cannot meet the high requirements for loading posture and accuracy. Summary of the Invention

[0006] In view of this, the present invention provides a top-mounted load double-layer loading and releasing device, which can realize the loading and releasing of double-layer or even multi-layer loads. It has a simple structure, reliable operation, stable posture, and high space utilization.

[0007] This invention is achieved through the following technical solution:

[0008] A top-mounted load double-layer loading and releasing device for loading and releasing top-mounted loads, comprising: a mounting frame and two release frame assemblies;

[0009] The mounting frame is fixedly mounted on the external carrier, and two release frame assemblies are arranged side by side, one above the other, inside the mounting frame.

[0010] When in the loading state, one top-mounted load is hoisted and connected to a release frame assembly via a top T-shaped lifting lug, and another top-mounted load is hoisted and connected to another release frame assembly via a top T-shaped lifting lug.

[0011] When it is necessary to release the top-mounted load, the release frame group at the bottom first releases the limit on the corresponding top-mounted load, and the top-mounted load can be released under the action of gravity. At the same time, the release frame group at the bottom opens to both sides to make way for the release channel of the top-mounted load at the top; the release frame group at the top then releases the limit on the corresponding top-mounted load, and the top-mounted load can be released under the action of gravity.

[0012] Furthermore, the mounting frame includes a top crossbeam, two bottom crossbeams, two U-shaped side frames, and two release frame mounting beam assemblies;

[0013] Each U-shaped side frame includes a top beam and two vertical beams, with the end where the top beam is located being the top of the U-shaped side frame, and the end opposite the top being the bottom.

[0014] Two U-shaped side frames are arranged side by side, and the two ends of the top beam are connected to the top of the two side frames respectively; the two U-shaped side frames are located at the left and right ends of the top beam respectively, and the two vertical beams of each U-shaped side frame are located at the front and rear ends of the U-shaped side frame respectively.

[0015] The two U-shaped side frames are U-shaped side frame I and U-shaped side frame II, respectively; the left end of one bottom crossbeam is connected to the bottom end of the vertical beam at the front end of U-shaped side frame I, and the right end is connected to the bottom end of the vertical beam at the front end of U-shaped side frame II; the left end of the other bottom crossbeam is connected to the bottom end of the vertical beam at the rear end of U-shaped side frame I, and the right end is connected to the bottom end of the vertical beam at the rear end of U-shaped side frame II.

[0016] Two release frame mounting beam assemblies are arranged side by side between U-shaped side frame I and U-shaped side frame II; the two release frame assemblies are connected to the two release frame mounting beam assemblies in a one-to-one correspondence.

[0017] Furthermore, a number of radial guide wheels and a number of axial guide wheels are provided on the left end face of the U-shaped side frame I located at the left end of the mounting frame; a number of radial guide wheels and a number of axial guide wheels are also provided on the right end face of the U-shaped side frame II located at the right end of the mounting frame; and locating pins are provided at the top of both the top of the U-shaped side frame I and the top of the U-shaped side frame II.

[0018] Furthermore, each release frame assembly includes two release frames; each release frame includes: two fixed hangers, two rotating arms, a tilting frame, and explosive bolts;

[0019] Let the two fixed hangers be the left fixed hanger and the right fixed hanger, and the two rotating arms be the left rotating arm and the right rotating arm;

[0020] The top of the left fixed hanger is connected to the mounting frame, and the bottom is pinned to one end of the left rotating arm via a pin. The other end of the left rotating arm is connected to the left end of the tilting frame.

[0021] The top of the right fixed hanger is connected to the mounting frame, and the bottom is pinned to one end of the right rotating arm via a pin. The other end of the right rotating arm is connected to the right end of the tilting frame.

[0022] When mounting a top-mounted load, the two release frames of each release frame group are arranged opposite each other, and the two flip frames of the two release frames are arranged side by side. The T-shaped lifting lugs on the top of each top-mounted load are clamped between the two flip frames. The expansion bolts are set in the middle of the two flip frames for connecting and limiting the two flip frames, thereby realizing the mounting of the top-mounted load.

[0023] Furthermore, the flipping frame is a rod-shaped structure with a through hole in the center and bayonets at both ends;

[0024] The through holes of the two flip frames of each set of release frames are coaxially aligned, and the two bayonets located at the same end of the two flip frames are aligned one to one;

[0025] Explosive bolts pass through opposite through holes to connect the two tilting frames, thereby limiting the tilting frames;

[0026] Each T-shaped lifting lug of the top-mounted load has one end engaged with a bayonet and the other end engaged with another opposite bayonet, thereby enabling the lifting of the top-mounted load.

[0027] Furthermore, the bottom surface of the bayonet is a slope.

[0028] Furthermore, each tilting frame has a rotating shaft on both ends, and the rotating shafts at both ends of the tilting frame are rotatably connected to the corresponding rotating arms.

[0029] Furthermore, each of the release frames also includes two booster stabilizing devices, which are located at the left and right ends of the release frame and are fixedly connected to the rotating arm. When in the loading state, the bottom end of the booster stabilizing device abuts against the top-mounted load; when in the release state, the booster stabilizing device can provide a downward thrust to the top-mounted load.

[0030] Furthermore, the booster stabilization device includes a mounting bracket, an outer sleeve, an inner sleeve, a limit pin, and a spring;

[0031] The inner sleeve has a cylindrical structure, and the outer sleeve also has a cylindrical structure with one end open and the other end closed. The inner sleeve is set inside the outer sleeve. The limiting pin is set on the outer circumferential surface of the inner sleeve. An axial guide groove is provided on the outer sleeve, and the limiting pin is located in the axial guide groove and can reciprocate along the axial guide groove.

[0032] The spring is set inside the outer sleeve, with one end of the spring abutting against the inner sleeve and the other end abutting against the inner bottom surface of the outer sleeve;

[0033] The mounting bracket is fixedly connected to the outer sleeve. The booster stabilizing device is fixedly mounted on the corresponding rotating arm through the mounting bracket. When in the loading state, the closed end of the inner sleeve of the booster stabilizing device abuts against the top-mounted load under the action of the spring.

[0034] Furthermore, the axial guide groove is an inverted U-shape, with one end of the U-shape penetrating the open end of the outer sleeve, and the other end extending along the axis to the closed end, then bending and turning 180 degrees, and then extending along the axis to near the open end.

[0035] Beneficial effects:

[0036] (1) By setting up two release frame groups in parallel, the present invention sets up a double-layer load in the mounting frame. First, it is only necessary to control the release frame group to release the limit on the corresponding top-mounted load to realize the release of the top-mounted load. Second, it improves the space utilization rate. Finally, it is only necessary to lift the T-shaped lifting lug on the top of the top-mounted load through the release frame group to realize the mounting of the top-mounted load, which is convenient for the mounting of the top-mounted load.

[0037] (2) The radial guide wheel and axial guide wheel of the present invention provide radial and axial guidance when the mounting frame is fixed on the external carrier, which can achieve the effect of saving effort; the positioning pin can be positioned when the mounting frame is fixed on the external carrier, so as to facilitate the installation of the mounting frame.

[0038] (3) The bottom of the release frame fixing bracket of the present invention is connected to the rotating arm by a pin. When the limit on the flipping frame is released, the flipping frame and the rotating arm can be in a vertical state under the action of gravity, which facilitates the release of the top-mounted load and also makes room for the release channel of the top-mounted load, thereby realizing the release of the double-layer load.

[0039] (4) The bottom surface of the bayonet of the present invention is a slope, which facilitates the release of the T-shaped lifting lug on the top of the top-mounted load.

[0040] (5) Each of the two ends of the flipping frame of the present invention is provided with a rotating shaft. The rotating shafts at both ends of the flipping frame are rotatably connected to the corresponding rotating arms, so that when loading and unloading the top-mounted load, the flipping frame can rotate around the rotating shaft to realize the smooth loading and unloading of the top-mounted load.

[0041] (6) Each of the release frames of the present invention further includes two booster stabilizing devices. When in the loading state, the bottom end of the booster stabilizing device abuts against the top-mounted load, which can stabilize the attitude of the top-mounted load. When in the release state, the booster stabilizing device can provide a downward thrust to the top-mounted load.

[0042] (7) The axial guide groove of the present invention is an inverted U-shape. One end of the U-shape passes through the open end of the outer sleeve 14, and the other end extends along the axis to the closed end and then bends and turns 180 degrees, and then extends along the axis to near the open end, so as to facilitate the installation of the inner sleeve and the limiting pin.

[0088] (2) Load the top-mounted load 3 into the mounting frame 1, and at the same time, make the rotating arm 9 fit with the top-mounted load 3. During the process of the top-mounted load 3 rising, adjust the position of the top-mounted load 3 and align the T-shaped lifting lug of the top-mounted load 3 with the bayonet 18 of the flipping frame 11.

[0089] (3) Rotate the flipping frame 11 until all the T-shaped lifting lugs are inserted into the bayonet 18;

[0092] Release process:

[0093] (1) When the explosive bolt 12 is energized, the explosive bolt explodes and separates, releasing the limit on the corresponding flipping frame 11 located below;

[0094] (2) The tilting frame 11 rotates around the rotating shaft 13, and at the same time the rotating arm 9 automatically rotates around the rotating pin 8 under the action of gravity, so as to release the constraint of the load T-shaped lifting lug.

[0095] (3) The lower release frame group is in a vertical state under the action of gravity, which can avoid the channel for the release of the upper load;

[0096] (4) Repeat steps (1) and (2) to release all the top-mounted loads 3 in sequence.
