Description

Technical Field

[0001] This invention relates to a loading and delivery device, specifically a multi-load loading and delivery device, belonging to the field of underwater unmanned vehicle technology. Background Technology

[0002] Underwater payload loading and delivery equipment refers to specialized equipment used for loading and dropping payloads in water; it is commonly used in underwater operations, marine research, underwater exploration, and diver support. The main function of underwater payload loading and delivery equipment is to accurately load payloads (such as sensors, tools, and equipment) from a surface or underwater location to a target location and then drop them back into the water when necessary. These devices typically have special designs and functions to adapt to the specific requirements of the underwater environment.

[0003] Existing loading and delivery equipment can mostly only be used for loading and delivery of a single load; and it also has the following drawbacks:

[0004] (1) Complex motion mechanism: It involves multiple moving parts and transmission system, which may increase the structural complexity of the loading and delivery equipment and make maintenance and operation more difficult;

[0005] (2) Large space occupation: It may restrict the use of the site, especially when loading and delivery operations are carried out in a limited space, the large space occupation may cause difficulties and inconvenience;

[0006] (3) High requirements for loading posture and precision: such as tasks that require loading and delivery at specific positions and angles;

[0007] (4) The load surface needs to be designed with a special attachment interface for loading: Some loads require a specific attachment interface to be loaded; this may require different attachment interfaces to be designed and manufactured for different loads, which increases the complexity and customization requirements of the loading and delivery equipment. Summary of the Invention

[0008] In view of this, the present invention provides a multi-load loading and delivery device that can solve the problem of loading multiple loads, and the load surface does not require a dedicated attachment interface, and the action mechanism is simple and reliable.

[0009] The technical solution of the present invention is: a multi-load loading and dispensing device, comprising: a loading frame and a plurality of locking and dispensing units stacked along the height direction of the loading frame; each locking and dispensing unit is used for locking and dispensing a load;

[0010] The locking and releasing unit includes: a tenon structure arm, a locking and releasing mechanism, and a driving mechanism;

[0011] One end of the locking and releasing mechanism is limited by a mortise and tenon joint with a tenon joint on the loading frame via a mortise and tenon joint arm, and the other end is connected to the driving mechanism via a locking arm. The driving mechanism is used to lock and unlock the locking arm.

[0012] When the load is in the loading state, it is limited to the loading frame in front of the locking and releasing mechanism or between two adjacent locking and releasing mechanisms.

[0013] As a preferred embodiment of the present invention, the locking and dispensing mechanism includes: a locking and dispensing frame, two mortise-and-tenon structural arms, and two locking arms;

[0014] The locking and launching frame is a rectangular frame structure used to support the load when loaded.

[0015] Two rotating arm mounting seats are provided on the crossbeam A on one side of the loading frame, and each rotating arm mounting seat is connected to a tenon structure arm by a pin; two mortise structure arms are provided on the side of the locking and launching frame opposite to the crossbeam A, which correspond one-to-one with the tenon structure arms.

[0016] Two locking arm mounting seats are provided on the crossbeam B on the other side of the loading frame, and a drive source mounting seat is provided on the crossbeam C; two locking arms corresponding to the locking arm mounting seats are provided on the side of the locking release frame opposite to the crossbeam B.

[0017] The drive source in the drive mechanism is mounted on the drive source mounting base. One end of the two locking release hooks in the drive mechanism is pinned to the locking arm mounting base, and the other end has a hook portion that cooperates with the locking arm. Under the drive of the drive source, the locking release hook rotates around the pin shaft that is pinned to the locking arm mounting base to achieve locking and unlocking with the locking arm.

[0018] In a preferred embodiment of the present invention, the locking and dispensing frame has two other sides with upper and lower opposing limiting rubbers B, the limiting rubbers B being arc-shaped surfaces, and the convex arc-shaped surfaces of the upper and lower limiting rubbers B facing each other; after the load is set, the locking and dispensing frame is in contact with the outer surface of the load above and / or below it through the arc-shaped limiting rubbers B.

[0019] In a preferred embodiment of the present invention, bottom elastic devices are provided at both ends of the upper limiting rubber B, and the bottom elastic devices are compressed and deformed when the load is in the loading state.

[0020] In a preferred embodiment of the present invention, top elastic devices are provided at both ends of the lower limiting rubber B; when the load is in the loading state, the top elastic devices are compressed and deformed.

[0021] In a preferred embodiment of the present invention, the limiting structure for the mortise and tenon joints is a one-way limiting structure. When the locking and releasing mechanism moves in the locking direction, the mortise joint is limited by the tenon joint; when the locking and releasing mechanism moves in the releasing direction, the limiting is released, and the mortise joint separates from the tenon joint.

[0022] In a preferred embodiment of the present invention, the base frame of the loading frame includes two arched frames and several crossbeams connecting the two arched frames; an arc-shaped limiting rubber A is provided between the top two crossbeams at the top, the limiting rubber A being used to limit the load at the top.

[0023] Both ends of the limiting rubber A are equipped with top elastic devices. When the load is in the loading state, the top elastic devices are compressed and deformed.

[0024] In a preferred embodiment of the present invention, each rotating arm mounting seat on the crossbeam A is connected to a tenon structure arm by a pin; the side of the pin hole on the tenon structure arm and the side of the pin hole on the rotating arm mounting seat are in a damped fit to ensure that the tenon structure arm will not rotate around the axis of the pin at the connection under its own weight.

[0025] In a preferred embodiment of the present invention, the driving mechanism simultaneously drives the locking and unlocking of the two locking arms on the locking and releasing frame through a single driving source;

[0026] The fixed end of the drive source is connected to the drive source mounting base, and the power output end is connected to the transverse connecting rod. Each end of the transverse connecting rod is connected to a locking release hook.

[0027] In a preferred embodiment of the present invention, the pin hole on the locking release hook that is connected to the locking arm mounting seat is called pin hole A; the bent portion of the hook part of the locking release hook is an arc surface B, the center of the arc surface B is concentric with the center of the pin hole A; the end of the locking arm has an arc surface A that mates with the arc surface B, and the arc surface A is concentric with the arc surface B of the locking release hook and has the same diameter.

[0028] Beneficial effects:

[0029] (1) The multi-load loading and delivery device of the present invention can realize the loading and sequential delivery of multiple loads; and has a compact structure, a simple loading process, low requirements for load attitude and accuracy, no additional installation interface requirements, simple action mechanism, and reliable delivery.

[0030] (2) In the multiple load loading and dispensing devices of the present invention, the mortise and tenon structure arms cooperate to form a one-way limiting structure. When dispensing, the locking dispensing mechanism is dispensing together with the load, opening up the dispensing channel of the upper load and ensuring the reliable dispensing of the upper load.

[0031] (3) In the multiple load loading and delivery devices of the present invention, the locking and delivery mechanism is provided with a top elastic device and a bottom elastic device. When the load is in the loading state, the top elastic device and the bottom elastic device are compressed and deformed. After unlocking, the top elastic device and the bottom elastic device can provide thrust to the load and accelerate the delivery of the load.

[0032] (4) In the multiple load loading and delivery devices of the present invention, the side of the pin hole on the tenon structure arm and the side of the pin hole on the rotating arm mounting base are damped, so that the tenon structure arm can maintain its posture at any angle within the stroke.

[0033] (5) In the multiple load loading and dispensing devices of the present invention, the end of the locking arm has an arc surface A that cooperates with the arc surface B. The arc surface A and the arc surface B of the locking release hook are concentric and have the same diameter. By setting them concentrically, it can ensure that the locking state has self-locking performance, avoid the existence of eccentric torque, and improve the loading reliability.

[0034] (6) The multi-load loading and delivery device of the present invention can vertically load multiple loads and horizontally connect multiple devices to realize the loading of multiple loads. The shape of the load is not limited to a rotating body (it is not a rotating body that can be limited, and point and line contact are also possible), etc., to meet the loading and delivery requirements of multiple working conditions and multiple loads.

Detailed Implementation

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0044] This embodiment provides a multi-load loading and delivery device that can load multiple loads in a small space with low requirements for loading posture and accuracy. The load surface does not require a dedicated attachment interface, and the action mechanism is simple and reliable.

[0045] like Figure 1 and Figure 2 As shown, the multi-load loading and dispensing device includes: a loading frame 1 and a plurality of locking and dispensing units stacked along the height direction of the loading frame 1; each locking and dispensing unit is used for locking and dispensing one load 18. As an example, two locking and dispensing units are stacked along the height direction of the loading frame 1, thereby enabling the load loading and dispensing device to lock and dispensing two loads 18.

[0046] The locking and releasing unit includes: a tenon structure arm 2, a locking and releasing mechanism 3, and a driving mechanism 4. One end of the locking and releasing mechanism 3 is limited by a tenon structure arm 2 set on the loading frame 1 through a mortise structure arm 11, and the other end is connected to the driving mechanism 4 through a locking arm 15. The driving mechanism 4 is used to lock and unlock the locking arm 15. When the load 18 is in the loading state, it is limited between the loading frame 1 and the locking and releasing mechanism 3 or between two adjacent locking and releasing mechanisms 3; that is, the load at the top is limited between the loading frame 1 and the locking and releasing mechanism 3, and the remaining loads are limited between two adjacent locking and releasing mechanisms 3.

[0047] Specifically: such as Figure 3As shown, the loading frame 1 is the main load-bearing structure, with the interior serving as the loading and delivery space. The loading frame 1 includes: a base frame 5, limiting rubber 6, rotating arm mounting base 7, drive source mounting base 8, locking arm mounting base 9, and a top elastic device 10. The loading frame 1 is a frame-type welded structure, thus the base frame 5 is a welded base frame. As an example, the base frame 5 includes two arched frames and several crossbeams connecting the two arched frames. As an example, a crossbeam A corresponding to the load 18 is provided along the height direction on one side of the base frame 5. Two rotating arm mounting bases 7 are provided on the crossbeam A, and the pin holes on the two rotating arm mounting bases 7 are coaxial. On the other side of the base frame 5, a group of crossbeams corresponding to the load 18 is provided along the height direction. Each group of crossbeams includes a crossbeam B and a crossbeam C arranged vertically. Two locking arm mounting bases 9 are provided on the crossbeam B, and the pin holes on the two locking arm mounting bases 9 are coaxial. A drive source mounting base 8 is provided on the crossbeam C. In addition, two crossbeams, referred to as crossbeams D, are also provided at the top of the base frame 5.

[0048] The inner wall of the arched frame is covered with non-metallic material, and the gap between the frame and the load 18 is controlled between 3mm and 5mm after the load 18 is loaded. Several arc-shaped limiting rubbers A6 are installed between the two top crossbeams D. The inner diameter of the limiting rubbers A6 is equal to the outer diameter of the load 18, and they are used to limit the load 18 at the top.

[0049] In addition, top elastic devices 10 (such as springs or other spring blocks, or any component that has elasticity after compression and deformation) are installed at both ends of the limiting rubber A6. When the load 18 is loaded, the top elastic devices 10 are provided with thrust, causing the top elastic devices 10 to compress and deform. The compression stroke of the top elastic devices 10 meets the requirements for the load 18 to contact the limiting rubber A6. The top elastic devices 10 are mainly used to accelerate the release of the load 18.

[0050] Each rotating arm mounting base 7 on the crossbeam A is pinned to a tenon-shaped structural arm 2. The side of the pin hole on the tenon-shaped structural arm 2 and the side of the pin hole on the rotating arm mounting base 7 are damped, allowing the tenon-shaped structural arm 2 to maintain its posture at any angle within its stroke (specifically, adjusting the friction between the contact surfaces of the tenon-shaped structural arm 2 and the rotating arm mounting base 7, ensuring that the tenon-shaped structural arm 2 will not rotate around the axis of the pin at the connection point under its own weight when no external force is applied). The tenon-shaped structural arm 2 is connected and separated from the locking and releasing mechanism 3 through a mortise and tenon joint.

[0051] like Figure 4 and Figure 5As shown, the locking and releasing mechanism 3 is a welded structure for mortise and tenon connection with the tenon arm 2, used for the setting and releasing of the load 18 (i.e., locking and unlocking of the load 18). The locking and releasing mechanism 3 includes: a locking and releasing frame 13, two tenon arms 11, and two locking arms 15; the locking and releasing frame 13 is a rectangular frame structure used to support the load 18 in the set state; two tenon arms 11 corresponding to the tenon arms 2 are provided on the side of the locking and releasing frame 13 opposite to the crossbeam A; the tenon arms 11 are unidirectional limiting structures, and when the locking and releasing mechanism 3 moves in the locking direction (e.g., when the locking and releasing mechanism 3 moves in the locking direction, the locking and releasing mechanism 3 can be locked in one direction). Figure 2 (As shown in the counterclockwise direction), the tenon arm 11 is limited by the tenon arm 2 and cannot be separated; when the locking and releasing mechanism 3 moves in the releasing direction (such as...), Figure 2 When the clockwise direction is shown, the limit is released, and the locking release frame 13 separates from the tenon structure arm 2.

[0052] Two locking arms 15 are provided on the side of the locking and dispensing frame 13 opposite to the crossbeam B, which correspond one-to-one with the locking arm mounting seat 9; the locking arms 15 cooperate with the drive mechanism 4 to realize the locking and unlocking of the locking and dispensing frame 13.

[0053] The locking and launching frame 13 has two other sides with upper and lower opposing limiting rubbers B14. The limiting rubbers B14 are arc-shaped, and the convex arc-shaped surfaces of the upper and lower limiting rubbers B14 are opposite to each other. After the load is set, the locking and launching frame 13 is in contact with the outer surface of the load 18 above and / or below it through the arc-shaped limiting rubbers B14.

[0054] In addition, bottom elastic devices 12 are provided at both ends of the upper limiting rubber B14 (after the load is set, the upper limiting rubber B14 contacts the bottom of the load; the bottom elastic device 12 can be a spring or other spring block, any component that has elasticity after compression and deformation); when the load 18 is loaded, pressure is applied to the bottom elastic device 12 to compress and deform the bottom elastic device 12; the bottom elastic device 12 ensures reliable contact between the load 18 and the limiting rubber B14; at the same time, the bottom elastic device 12 also provides thrust for unlocking the locking release frame 13.

[0055] Top elastic devices 10 are provided at both ends of the lower limiting rubber B14 (after the load is set, the lower limiting rubber B14 contacts the top of the load); the top elastic device 10 has the same function as the top elastic devices 10 provided at both ends of the limiting rubber A6; when the load 18 is loaded, a thrust is provided to the top elastic device 10, causing the top elastic device 10 to compress and deform; the compression stroke of the top elastic device 10 meets the requirement of the load 18 contacting the limiting rubber B14, and the top elastic device 10 is mainly used to accelerate the release of the load 18.

[0056] During loading, the locking and releasing mechanism 3 is connected to the loading frame 1 as a whole by the limiting cooperation of the tenon structure arm 2 and the mortise structure arm 11 and the locking arm 15 by the drive mechanism 4; during release, the drive mechanism 4 releases the locking arm 15, and under the dual action of the load gravity and the top elastic device 10, the locking and releasing mechanism 3 and the tenon structure arm 2 are accelerated to separate and are released together with the load 18.

[0057] The drive mechanism 4 is used to lock and unlock the locking arm 15 of the locking and dispensing mechanism 3; the drive mechanism 4 simultaneously drives the locking and unlocking of both locking arms 15 on the locking and dispensing frame 13 via a drive source 17; based on this, as Figure 6 and Figure 7 As shown, the drive mechanism 4 includes a drive source 17 and two locking release hooks 16. The drive source 17 can be a hydraulic cylinder, an electric cylinder, or a linear motor. The fixed end of the drive source 17 is connected (pin-connected) to the drive source mounting seat 8 on the crossbeam C. The power output end of the drive source 17 is connected to the transverse connecting rod. Each end of the transverse connecting rod is connected to a locking release hook 16, i.e., the two locking release hooks 16 are symmetrically arranged relative to the drive source 17. One end of the locking release hook 16 is pin-connected to the locking arm mounting seat 9 on the crossbeam B via a pin shaft (the pin hole axis on the drive source mounting seat 8 is parallel to the pin hole axis on the locking arm mounting seat 9); the other end has a hook portion that cooperates with the locking arm 15. The locking release hook 16 can rotate around the pin shaft pin-connected to the locking arm mounting seat 9 under the drive of the drive source 17 to achieve locking and unlocking with the locking arm 15.

[0058] To ensure reliable locking and unlocking, the locking release hook 16 can reliably engage with the locking arm 15, and the pin hole on the locking release hook 16 that connects with the locking arm mounting base 9 is designated as pin hole A. The bent portion of the hook of the locking release hook 16 is an arc surface B, and the center of the arc surface B is the center of the pin hole A. The end of the locking arm 15 has an arc surface A that engages with the arc surface B. The arc surface A and the arc surface B of the locking release hook 16 are concentric and have the same diameter. This concentric arrangement ensures self-locking performance in the locked state, avoids the presence of eccentric torque, and improves loading reliability.

[0059] The device is loaded sequentially from top to bottom, and the loading process is as follows:

[0060] Step 11: The drive source 17 extends to push the locking release hook 16 away from the locking arm 15, and removes the locking release mechanism 3 from the loading frame 1;

[0061] Step 12: Load 18 is inserted so that the surface of load 18 contacts the limiting rubber A6 at the top of the loading frame 1. At this time, the top elastic device 10 is compressed and deformed to generate thrust. The locking and launching mechanism 3 is assembled by the cooperation of the tenon structure arm 2 and the mortise structure arm 11 (that is, the mortise structure arm 11 of the locking and launching mechanism 3 is connected to the tenon structure arm on the loading frame 1 to realize the assembly of the locking and launching mechanism 3 and the loading frame 1).

[0062] Step 13: Rotate the locking and releasing mechanism 3 upward (rotate around the pin joint between the tenon structure arm 2 and the rotating arm mounting seat 7) so that the limiting rubber B14 on the upper surface of the locking and releasing frame 13 contacts the surface of the load 18. At this time, the bottom elastic device 12 is compressed and deformed to generate thrust; the drive source 17 retracts, so that the locking release hook 16 cooperates with the locking arm 15. At this time, the arc surface B of the locking release hook 16 fits with the arc surface A of the locking arm 15, completing the assembly of the top load 18.

[0063] Repeat steps 12 and 13 from top to bottom to complete the assembly of all loads; the only difference is that when loading the lower load, the top of the lower load contacts the limiting rubber B14 on the lower surface of the upper locking and delivery frame 13.

[0064] The device is deployed sequentially from bottom to top, and the deployment process is as follows:

[0065] Step 21: The drive source 17 extends, pushing the locking release hook 16 to disengage from the locking arm 15;

[0066] Step 22: The locking and releasing mechanism 3 rotates (clockwise) under the combined action of the load gravity and the top elastic device 10 and bottom elastic device 12. At the same time, the tenon structure arm 2 and the mortise structure arm 11 disengage. The locking and releasing mechanism 3 completes the release together with the load 18, thereby opening the release channel of the upper load.

[0067] Repeat steps 21 and 22 from bottom to top to complete the deployment of all loads 18 in sequence.

[0068] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
