Description

Technical Field

[0001] This invention relates to the field of underwater payload launch technology, and more particularly to a payload delivery device. Background Technology

[0002] The payload launch device is located at the head of the underwater launch platform, which typically carries three or four payloads. These payloads are launched through a launch tube, powered by a gas propulsion system that uses high-pressure gas or combustion gas as a power source. If a gas leak occurs in the gas propulsion system after the payload is launched horizontally into the water—for example, due to improper sealing between the system and the payload, or an imbalance between the internal pressure of the launch tube and the external seawater pressure—the payload's initial velocity will lag behind the target velocity, causing it to lose propulsion and deviate from its intended launch trajectory.

[0003] Due to insufficient payload speed, it is more susceptible to drift caused by water currents when moving through the water, leading to a greater deviation between the landing point and the target point. Simultaneously, because the underwater launch platform is in normal motion, while the payload's launch speed lags behind the target speed and is significantly lower than the platform's travel speed, this creates a dangerous situation where the payload might collide with the platform, thus indicating room for improvement. Summary of the Invention

[0004] In view of the above problems, embodiments of the present invention provide a load delivery device that can realize the vertical delivery of loads.

[0005] This invention provides a payload delivery device installed on an underwater payload launch platform. The payload delivery device includes: multiple payload loading frames, a rotating payload sleeve, a rotating assembly, and a drive component; the multiple payload loading frames are provided with first mating parts; the rotating payload sleeve is provided with multiple second mating parts, the first mating parts and the second mating parts being slidably mated; the rotating payload sleeve is sleeved on the rotating shaft of the rotating assembly; the drive component is drively connected to the rotating shaft of the rotating assembly; wherein the drive connection is configured to transmit power from the drive component to the rotating shaft, causing the rotating shaft to rotate, thereby causing the payload loading frames to rotate to a payload delivery area, and the payload delivery area is configured as the payload delivery outlet on the payload loading frame, the delivery outlet being oriented towards the direction of the payload's gravity.

[0006] According to one embodiment of the present invention, the load delivery device further includes: a strap and an explosive bolt; the strap is connected to the side of the load loading frame opposite to the first mating part; the side of the load loading frame opposite to the first mating part is detachably connected to the strap via the explosive bolt.

[0007] According to one embodiment of the present invention, the load loading frame is provided with a mounting part for mounting a load, the mounting part being disposed opposite to the first mating part, the mounting part forming a curved surface recess adapted to the shape of the load, the curved surface recess being used to fit the outer periphery of the load.

[0008] According to one embodiment of the present invention, the driving component is a drive motor, and the drive motor is a rotary motor.

[0009] In some embodiments, the transmission connection is a coupling connection, with one end of the coupling connected to the rotating shaft and the other end connected to the output shaft of the rotating motor. The coupling is configured to transmit the power of the rotating motor to the rotating shaft, thereby driving the rotating shaft to rotate; or, the transmission connection is any one of a gear transmission connection or a belt transmission connection.

[0010] According to one embodiment of the present invention, one of the first mating part and the second mating part forms a groove, and the other forms a slider. The slider is inserted into the groove, and the groove is slidably connected to the slider.

[0011] In some embodiments, the first mating portion forms a slider, the second mating portion forms a groove, the slider slides into the groove, and the groove extends in the direction of the arrangement of the wheel load sleeve.

[0012] According to one embodiment of the present invention, the load delivery device further includes: a cabin, a hollow structure, wherein a support base and a support seat are provided inside, the support seat and the support base respectively supporting the drive member and the load loading frame.

[0013] In some embodiments, the load delivery device further includes: a hatch hydraulic rod, wherein the cabin body has a hatch opening, the hatch is provided with a double-leaf hatch, and the connection between the double-leaf hatch and the hatch is movably connected by the hatch hydraulic rod; wherein the opening direction of the double-leaf hatch is the same as the direction of the delivery outlet.

[0014] According to one embodiment of the present invention, the load delivery device further includes: a stop plate, sleeved on the rotating shaft, and the stop plate being in close contact with the rotating load sleeve.

[0015] In the payload delivery device of this invention, the driving component is connected to the rotating shaft of the rotating assembly, and the rotating shaft drives the outer rotating payload sleeve to rotate synchronously through power transmission. The rotating payload sleeve has multiple payload loading frames circumferentially arranged, which are slidably connected to each other, thereby driving the payload loading frames to rotate. The payload is installed in the mounting part of the payload loading frame and rotates synchronously with the payload loading frame. The driving component precisely controls the speed and angle of the rotating shaft, so that the payload on the payload loading frame is precisely aligned with the payload delivery area through rotation, and the delivery area is consistent with the direction of gravity (vertically downward) of the payload. When the payload loading frame rotates to the delivery area, the payload receives the delivery command and is delivered vertically along the direction of gravity, completely detaching from the underwater launch platform. This solves the problem of insufficient sealing in the pneumatic propulsion system and the imbalance between the pressure inside the launch tube and the seawater pressure, resulting in a payload launch speed lower than the predetermined speed. It avoids the risk of payload collision with the platform caused by speed lag, eliminates the interference of low-speed water flow on the payload trajectory, solves the problem of payload easy deviation and difficulty in accurately hitting the target, and improves the safety and stability of underwater launch. By circumferentially setting multiple load loading racks on the rotating load sleeve, with one load installed on each load loading rack, the load capacity is increased, and the number of repeated and frequent loading caused by insufficient load capacity is reduced.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] Figure 1 This is a schematic diagram of a payload delivery device according to an embodiment of the present invention, wherein the payload delivery device is mounted on a payload launch platform. Figure 2 This is a schematic diagram of the internal structure of the load delivery device; Figure 3 This is a structural diagram of the hatch in the open position; Figure 4 This is a schematic diagram of the assembly of the rotating load sleeve 20 with the load loading frame 10 and the load loading frame 10 with the load; Figure 5 This is a structural schematic diagram of the rotating load sleeve 20; Figure 6 This is a schematic diagram of the assembly of the load loading frame 10 and the load; Figure 7 A structural schematic diagram of the load loading frame 10; as shown. Figures 1 to 7 As shown, a payload delivery device 100 is installed on an underwater payload launch platform. The payload delivery device 100 includes: multiple payload loading frames 10, a rotating payload sleeve 20, a rotating assembly, and a drive component 40.

[0029] In order to install multiple payloads 11 on the underwater launch platform and improve launch efficiency, such as Figure 6 As shown, the load delivery device 100 includes: a plurality of load loading racks 10, each having a first mating part 101. The load loading racks 10 are used to install loads 11, and each load loading rack 10 has one load 11 installed on it. There are multiple load loading racks 10, and multiple loads 11 are installed on the multiple load loading racks 10.

[0030] In order to enable the operation of the load loading frame 10, so that the load 11 can be vertically deployed along the direction of gravity under its own weight, such as... Figure 5 and Figure 6 As shown, the payload delivery device 100 also includes a rotating payload sleeve 20, which has multiple second mating parts 201, with the first mating part 101 slidingly engaging with the second mating parts 201. Specifically, the payload loading frame 10 is provided with the first mating part 101 to achieve a sliding connection with the multiple second mating parts 201 provided on the rotating payload sleeve 20, allowing the payload loading frame 10 to be installed on the outer periphery of the rotating payload sleeve 20. The rotating payload sleeve 20 has a cylindrical hollow structure, and the second mating parts 201 are located on the outer periphery of the rotating payload sleeve 20 to achieve a mating connection with the first mating part 101. The reason for providing multiple payload loading frames is to arrange multiple payload loading frames sequentially circumferentially along the outer periphery of the rotating payload sleeve 20, thereby enabling the carrying of multiple payloads 11, and also improving the effective utilization rate of the space of the underwater launch platform. The sliding fit is used to facilitate the installation of the load 11 and the limiting of the load 11. That is, when installing the load 11, the load loading frame 10 needs to be disassembled by sliding connection, the load 11 is installed on the disassembled load loading frame 10, and then the load loading frame 10 with the load 11 installed is reinstalled on the rotating load sleeve 20 by sliding connection, thereby facilitating the installation of the load 11.

[0031] If an underwater launch platform is limited by space and can only accommodate three or four payload 11 systems, it must be reinstalled after each launch, which is time-consuming and reduces launch efficiency. Installing multiple payload 11 systems at once reduces the frequency of reinstallation, avoids launch interruptions due to installation, and improves overall launch efficiency.

[0032] In order to allow the rotating load sleeve 20 to rotate around the central axis, thereby driving the load loading frame 10 to rotate as well, and to achieve the vertical deployment of the load 11 in the direction of gravity, as follows: Figure 5 As shown, the load delivery device 100 also includes a rotating assembly, with the rotating load sleeve 20 mounted on the rotating shaft 30 of the rotating assembly. This design allows the rotating load sleeve 20 to rotate together with the rotating shaft 30 of the rotating assembly during rotation, thereby positioning the load 11 on the load loading frame at a predetermined position and enabling the load 11 to be delivered vertically.

[0033] Eight loaders 10 can be installed on the rotating load sleeve 20, or ten or more. The number of loaders 10 installed on the rotating load sleeve 20 is not limited in this invention. However, eight loaders 10 are preferably installed on the rotating load sleeve 20 in this invention. The eight loaders 10 correspond to eight mounting parts 102, and the eight mounting parts 102 install eight loaders 11.

[0034] When the first load 11 is vertically deployed, if the first load 11 is not in the predetermined position, the rotating shaft 30 needs to be rotated by a predetermined angle, such as 15°, 25°, or other degrees. The rotation of the rotating shaft 30 can drive the rotating load sleeve 20 to rotate synchronously until the load 11 is in the predetermined position, so as to realize the vertical deployment of the load 11.

[0035] When the second payload 11 needs to be vertically deployed, the rotating shaft 30 rotates by a predetermined angle, for example, preferably 45°. The rotating payload sleeve 20 rotates, causing the payload loading frame to rotate. By rotating, the original first payload loading frame is rotated to another position, while the second payload is rotated to align with the predetermined position, thus achieving the vertical deployment of the second payload. This process is repeated until the eighth payload is vertically deployed. The process is continuous and there is no situation where frequent reinstallation of payloads due to a small number of payloads reduces launch efficiency.

[0036] In order to enable the rotating shaft 30 to rotate, such as Figure 2As shown, the load delivery device 100 also includes a drive component 40, which is connected to the rotating shaft 30 of the rotating assembly. Specifically, the drive component 40 is connected to the rotating shaft 30 of the rotating assembly, providing precise and controllable power to the rotating shaft 30. During load delivery, the drive component 40 can precisely control the rotation angle and speed of the rotating shaft 30 as needed. For example, when the first load is not in the predetermined delivery position, the drive component 40 can precisely drive the rotating shaft 30 to rotate by an angle of 15° or 25°, thereby rotating the rotating load sleeve 20 and the load loading frame 10 mounted on it, adjusting the load to the predetermined delivery point. When the second load needs to be delivered, the drive component 40 can drive the rotating shaft 30 to rotate, preferably by 45°, to move the second load to the predetermined delivery point. The vertical launch method achieved through gravity ensures that the payload separates from the underwater launch platform the instant it detaches, completely avoiding the risk of collision due to speed differences. At the same time, it reduces the interference of water flow on low-speed payloads, ensuring the continuity and trajectory stability of the launch process for eight or more payloads, and significantly improving the launch performance of the underwater launch platform.

[0037] The transmission connection is configured to transmit the power of the drive component 40 to the rotating shaft 30, thereby rotating the rotating shaft 30 to rotate the load loading frame 10 to the load delivery area. The load delivery area is configured as the load delivery outlet on the load loading frame 10, and the delivery outlet is set in the direction of the load gravity so that the load is delivered vertically.

[0038] Specifically, the drive component 40 and the rotating shaft 30 are connected by a transmission mechanism. This connection ensures that the power generated by the drive component 40 can be transmitted completely and stably to the rotating shaft 30. When the drive component 40 starts, its output power is directly applied to the rotating shaft 30 through the transmission connection, causing the rotating shaft 30 to start rotating. Since the wheel load sleeve 20 is fitted on the rotating shaft 30, and the load loading frame 10 is in sliding fit with the wheel load sleeve 20, the rotation of the rotating shaft 30 will sequentially drive the wheel load sleeve 20 and the load loading frame 10 to rotate.

[0039] The rotating shaft 30 continues to rotate until the load loading frame 10 is rotated to the pre-set load delivery area (i.e., the predetermined delivery point). The load delivery area is the exit area used to deliver the load. The exit direction of this area is completely consistent with the direction of gravity of the load, that is, vertically downward. When the load loading frame 10 rotates to the load delivery area, the load installed on the load loading frame 10 will be vertically delivered from this delivery outlet along its own gravity direction.

[0040] This invention utilizes a design where the driving component 40 is connected to the rotating shaft 30 to drive the load loading frame 10 to rotate. Combined with a vertically downward load delivery area, this achieves vertical load delivery, thus solving the problem of insufficient sealing and pressure imbalance between the launch tube and seawater in traditional pneumatic propulsion systems, which leads to load launch speeds lower than predetermined speeds. It avoids the risk of collision between the load and the underwater launch platform due to speed lag, and eliminates the interference of water flow on the load trajectory at low speeds. This effectively solves the problems of load deviation and difficulty in accurately hitting targets in traditional technologies, improving the safety and stability of underwater launches.

[0041] It should be noted that the payload in this invention is installed on the payload delivery device of the underwater launch platform. It can be a payload for detecting water quality and temperature, a life-saving payload, or other payloads with different functions that achieve mission objectives through the underwater launch platform and payload delivery device. The type of payload is not limited in this invention.

[0042] In this invention, the payload is preferably a life-saving payload. For example, when performing underwater rescue, a life-saving payload can be launched. After the life-saving payload falls vertically to the vicinity of the underwater trapped person, the life-saving payload with positioning function can quickly identify the location information of the trapped person and feed back the obtained location information of the trapped person to the rescuers. The rescuers can then successfully rescue the trapped person based on the location information.

[0043] In the payload delivery device 100 of this embodiment, the drive component 40 is connected to the rotating shaft 30 of the rotating assembly, and the rotating shaft 30 drives the rotating payload sleeve 20 on its outer periphery to rotate synchronously through power transmission. The rotating payload sleeve 20 has multiple payload loading frames 10 circumferentially arranged, which are slidably connected to each other, thereby driving the payload loading frames 10 to rotate. The payload is installed in the mounting part 102 of the payload loading frame 10 and rotates synchronously with the payload loading frame 10. The drive component 40 precisely controls the speed and angle of the rotating shaft 30, so that the payload on the payload loading frame 10 is precisely aligned with the payload delivery area through rotation, and the delivery area is consistent with the direction of gravity of the payload (vertically downward). When the payload loading frame 10 rotates to the delivery area, the payload receives the delivery command and is delivered vertically along the direction of gravity, completely detaching from the underwater launch platform. This solves the problem of insufficient sealing in the air-propulsion system and the imbalance between the pressure inside the launch tube and the seawater pressure, which leads to the payload launch speed being lower than the predetermined speed. It avoids the risk of payload collision with the platform caused by speed lag, eliminates the interference of low-speed water flow on the payload trajectory, and solves the problems of payload easy deviation and difficulty in accurately hitting the target in traditional technologies, thus improving the safety and stability of underwater launch. By setting multiple payload loading racks 10 on the rotating payload sleeve 20, with one payload installed on each load loading rack 10, the payload capacity is increased, the number of repeated loadings due to low load capacity is reduced, and the launch efficiency is improved. According to an embodiment of the present invention, the payload delivery device 100 also includes: a strap 50, an explosive bolt 51, and a control system.

[0044] In order to fix the load to the mounting part 102, such as Figure 4 As shown, combined with Figure 7 As shown, the load delivery device 100 also includes a strap 50 connected to the side of the load loading frame 10 opposite to the first mating part 101. Specifically, the strap 50 is made of nylon, which is flexible and can better conform to the outer periphery of the load. One end of the strap 50 is fixedly connected to the end of the load loading frame 10 opposite to the first mating part 101, and the other end of the strap 50 is detachably connected to the other end of the load loading frame 10 opposite to the first mating part 101 via an expansion bolt 51, thereby fixing the load to the load loading frame 10 via the strap 50.

[0045] The control system is electrically connected to the explosive bolt 51. Under the condition that the load is precisely aligned with the load release port, after receiving the command from the control system, the explosive bolt 51 unlocks and separates by igniting and detonating, releasing the constraint of the strap 50, so that the load is released from the load loading frame 10 and falls vertically in the direction of the load release port. This achieves complete separation from the underwater launch platform and avoids the load from drifting due to the large interference of water flow at low speed, thus deviating from the preset trajectory.

[0046] According to one embodiment of the present invention, in order to facilitate load installation and achieve structural weight reduction, the load loading frame 10 is provided with a mounting portion 102 for installing the load. The mounting portion 102 and the first mating portion 101 are arranged facing away from each other. Figure 7 As shown, the mounting portion 102 forms a curved recess that adapts to the shape of the load, and the curved recess is used to fit the outer periphery of the load. That is, the load is inserted along the direction of the curved recess, and the load and the curved recess are fully matched, thereby realizing the loading of the load. In this invention, a portion of the outer periphery of the load matches the curved recess, and the other portion is fixed to both ends of the mounting portion 102 by straps 50. That is, part of the load is flexibly matched, and the other part is rigidly matched. When it is necessary to vertically place the load, only the flexible part needs to be opened to achieve vertical placement of the load.

[0047] By setting up multiple load racks 10, which are circumferentially arranged around the rotating load sleeve 20, and each load rack 10 is provided with a mounting part 102 for mounting loads, such as torpedoes, multiple loads can be mounted on the underwater launch platform. At the same time, the multiple loads are also circumferentially mounted along the path of the load racks 10. The circumferential arrangement of the load racks 10 and the circumferential mounting of the loads are mainly to enable the underwater launch platform to carry multiple loads, increase the number of loads carried, optimize space utilization and load loading efficiency, thereby avoiding the situation in traditional technologies where only three or four loads can be mounted on the load launch platform.

[0048] Furthermore, the mounting part 102 and the first mating part 101 are arranged facing away from each other. Specifically, the mounting part 102 is provided to allow the load to be installed inside the mounting part 102, while the first mating part 101 is provided to fix the load loading frame 10 onto the rotating load sleeve 20 through a sliding connection with the second mating part 201. The back-to-back design of the mounting part 102 and the first mating part 101 is to allow the load to be installed on the load loading frame 10 in a convenient and quick manner, and also to allow the load loading frame 10 with the load installed to be installed on the rotating load sleeve 20 more flexibly and conveniently, because the rotating load sleeve 20 enables the operation of the load loading frame 10, and the operation of the load loading frame 10 enables the vertical placement of the load.

[0049] According to one embodiment of the present invention, in order to enable the rotating shaft 30 to rotate precisely, so as to accurately align the load with the load delivery area and realize the vertical delivery of the load in the direction of gravity, the driving component 40 is a driving motor, but it can also be other structures that can provide power; the present invention is not limited thereto. In the present invention, the driving component 40 is preferably a driving motor, and the driving motor is a rotary motor. In order to realize the rotation of the rotating shaft 30, the driving motor can be a rotary motor, and the present invention prefers a rotary motor, but it can also be other structures that can provide rotation function; the present invention is not limited thereto. In order to enable the rotating shaft 30 to precisely control the speed and angle of rotation, so as to accurately align the load with the load delivery port and realize the vertical delivery of the load in the direction of gravity, the driving motor / rotary motor is a servo motor, and the servo motor can precisely control the rotation accuracy.

[0050] In some embodiments, such as Figure 2 As shown, the transmission connection is a coupling 41. One end of the coupling 41 is connected to the rotating shaft 30, and the other end is connected to the output shaft of the rotating motor. The coupling 41 is configured to transmit the power of the rotating motor to the rotating shaft 30, causing the rotating shaft 30 to rotate. The rotating shaft 30 drives the wheel-rotating load sleeve 20 and the load loading frame 10 to rotate synchronously, so that the load loading frame 10 is precisely aligned with the load delivery area, thereby achieving the vertical delivery of the load in the direction of its own gravity. The coupling 41 transmits power through an elastic structure and can also compensate for axial deviation, ensuring the stability of power transmission.

[0051] In other embodiments, the transmission connection can be either a gear transmission connection or a belt transmission connection, both of which can achieve power transmission.

[0052] When the transmission connection is a gear drive, a driving gear is installed on the output shaft of the drive motor, and a driven gear is installed on the rotating shaft 30. Power is transmitted through the meshing of the gears. Gear drives have accurate transmission ratios and high transmission efficiency, and can be used in scenarios where speed can be precisely controlled.

[0053] When the transmission connection is belt drive, pulleys are installed on the output shaft of the drive motor and the rotating shaft 30 respectively, and the belt is used to connect them, using friction to transmit power. Belt drive can buffer shocks, provide overload protection, and reduce the impact during device operation.

[0054] All of the above-mentioned different transmission connection methods (coupling 41, gear transmission, belt transmission, etc.) can achieve the function of transmitting the power of the drive motor to the rotating shaft 30, ensuring that the wheel assembly drives the load loading frame 10 to rotate to the load delivery area, so as to achieve vertical load delivery. In this invention, the transmission connection is preferably the coupling 41.

[0055] According to one embodiment of the present invention, in order to facilitate the assembly and disassembly of the load loading frame 10, such as... Figure 5 and Figure 6 As shown, one of the first mating part 101 and the second mating part 201 forms a groove, and the other forms a slider. The slider is inserted into the groove, and the groove and the slider are slidably connected to realize the assembly and disassembly of the load loading frame 10.

[0056] Specifically, the first mating part 101 forms a slider, and the second mating part 201 forms a groove. The slider is inserted into the groove and slidably connected to the groove to realize the assembly and disassembly of the load loading frame 10. Similarly, the first mating part 101 forms a groove, and the second mating part 201 forms a slider. The slider is inserted into the groove to realize the sliding assembly and disassembly of the load loading frame 10.

[0057] In some embodiments, the first mating part 101 preferably forms a slider, and the second mating part 201 forms a groove. The groove is slidably connected to the slider to realize the assembly and disassembly of the load loading frame 10, and the groove extends in the direction of the arrangement of the rotating load sleeves 20. The groove has a guiding function; the slider is inserted into the groove and slides along the direction of the groove's extension to a predetermined position to realize the assembly and disassembly of the load loading frame 10. In this invention, the assembly of the load loading frame 10 is mainly achieved by the slider and the groove being slidably connected.

[0058] According to one embodiment of the present invention, such as Figure 2 As shown, the load delivery device 100 also includes: a cabin 60, a hollow structure, which has a support base 601 and a support seat 602 inside, and the support seat 602 and the support base 601 respectively support the drive component 40 and the load loading frame 10.

[0059] Specifically, the cabin 60 has a hollow, square-shaped structure, with support bases 601 and support seats 602 spaced apart at its bottom. Two identical first support plates are mounted on the support bases 601, spaced apart to form a first installation area. This area communicates with the load delivery area. The rotating shaft 30 of the rotating assembly, the rotating load sleeve 20 fitted onto the rotating shaft 30, and the load loading frame 10 mounted on the rotating load sleeve 20 are all located within the first installation area. The rotating shaft 30 is supported by the two support bases 601, thus providing support for the rotating load sleeve 20 and the load loading frame 10.

[0060] The support base 602 is also equipped with two second support plates, which are spaced apart to form a second mounting area for mounting the drive motor. The output shaft of the drive motor passes through one of the support plates and is connected to the coupling 41. The other end of the coupling 41 is connected to the rotating shaft 30, while the other end of the drive motor's output shaft passes through the other support plate to achieve the mounting of the drive motor. Through the above design, during the operation of the drive motor and the wheel assembly, the support base 602 and the support base 601 can distribute the force and maintain the force balance, ensuring the stability of the overall structure of the load delivery device 100.

[0061] In some embodiments, in order to achieve vertical load delivery, such as Figures 1-3 As shown, the load delivery device 100 also includes: a hatch hydraulic rod 605; a hatch 604 is provided on the hull 60; the hatch 604 is equipped with a double-leaf hatch 603; the connection between the double-leaf hatch 603 and the hatch 604 is movably connected by the hatch hydraulic rod 605; wherein, the opening direction of the double-leaf hatch 603 is the same as the direction of the delivery outlet. Specifically, to achieve fully automatic vertical load delivery, when the control system issues a delivery command, the hatch hydraulic rod 605 automatically starts, driving the double-leaf hatch 603, which is movably connected to the hatch 604, to open along the delivery outlet direction, so that the hatch 604 is fully exposed. At this time, the load loading frame 10 is precisely aligned with the hatch 604 below the load delivery outlet, ensuring that the load can be delivered vertically and smoothly by passing through the load delivery outlet and the hatch 604 in sequence in the direction of gravity. The load delivery outlet is a virtual channel defined based on the direction of load gravity.

[0062] According to one embodiment of the present invention, in order to limit the sliding fit structure between the slider and the groove, and prevent the slider from moving within the groove, so as to ensure the stability and reliability of the overall structure of the load delivery device 100, and avoid problems such as loose assembly and misalignment of components caused by slider displacement, thereby affecting the normal realization of the load delivery function. Figure 5 As shown, the load delivery device 100 further includes a stop plate 42, which is sleeved on the rotating shaft 30 and closely abuts the end face of the rotating load sleeve 20. Specifically, the stop plate 42 is disposed on the rotating shaft 30 and closely abuts the end face of the rotating load sleeve 20. By sleeved on the rotating shaft 30 and connected to the rotating load sleeve 20, a limiting structure is formed, thereby preventing the slider from displacing within the groove, ensuring the stability of the load loading frame 10 assembly structure, and maintaining the stability of the overall device during operation. In addition, the stop plate 42 and the rotating load sleeve 20 are fixed together by bolts 43.
