Description

Technical Field

[0001] This utility model relates to the field of boarding technology, and in particular to a wave compensation boarding device with multi-axis linkage. Background Technology

[0002] A multi-axis linkage wave compensation boarding device refers to a special device that achieves real-time dynamic compensation for the complex motions of ships under the action of waves, such as roll, pitch, and heave, by the coordinated action of multiple directional axes, so as to keep the end of the boarding pier stable and ensure the safe transfer of personnel or materials.

[0003] Currently, when this device is in use, it is usually adjusted in a multi-axis linkage manner to adjust the orientation and height of the boarding device so that it can be better connected with other ships and facilitate boarding. However, during the multi-axis linkage process, the device is easily affected by waves and is prone to swaying, which reduces the stability of the boarding device during multi-axis linkage.

[0004] Meanwhile, the use of guardrails to protect people during boarding makes them vulnerable to external factors and reduces their safety.

[0005] Therefore, we propose a multi-axis linkage wave compensation boarding device to solve the problems mentioned above. Utility Model Content

[0007] To achieve the above objectives, the present invention adopts the following technical solution: including a boarding platform, a stabilizing mechanism, and a protective mechanism. The stabilizing mechanism includes a tension rod and a base. The bottom end of the tension rod is fixedly connected to the base. The tension rod and the base are used to improve the stability of the multi-axis linkage of the device, thereby enabling wave compensation of the device.

[0008] The protective mechanism includes a protective ring and a stop block. The front and rear surfaces of the protective ring are fixedly connected to the stop block. The protective ring and the stop block are used to protect passengers and prevent danger.

[0009] Preferably, the stabilizing mechanism further includes a retractable tube, the top end of which is movably connected to the lower surface of the boarding platform via a joint, the interior of which is slidably connected to a tension rod, a counterweight is fixedly connected to the upper surface of the base, a connecting tube is fixedly connected to the inner top wall of the base, and a ball bearing is movably connected to the interior of the connecting tube.

[0010] Preferably, the protective mechanism further includes a sliding seat, the rear surface of which is movably connected to a movable seat via a bearing, and the front surface of the movable seat is fixedly connected to the protective ring. The inner wall of the protective ring is provided with sponge, and a handle is fixedly connected to the upper surface of the protective ring.

[0011] Preferably, a guardrail is fixedly connected to the upper surface of the boarding platform, and a sliding plate is fixedly connected to both the front and rear surfaces of the guardrail. The interior of the sliding plate is slidably connected to a sliding seat. A swing seat is fixedly connected to the lower surface of the boarding platform. A lifting seat is movably connected to the front surface of the swing seat via a bearing. A support frame is fixedly connected to the upper surface of the lifting seat.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, when the mechanism is placed on or applied to an uneven deck, or when the relative position between the deck and the bottom of the mechanism changes due to the rocking of the ship, the ball first contacts the deck. The deck pushes the base upward through the ball, forcing the tension rod to slide upward and retract slightly into the contraction tube. The tension rod adjusts the extension length in real time according to the dynamic balance between the deck reaction force on the base and the weight of the counterweight, ensuring that the ball always effectively contacts the deck surface, so that the tension rod and the contraction tube can improve the stability of the device during multi-axis movement.

[0016] 2. In this utility model, the movable connection between the movable seat and the sliding seat allows the movable plate to be moved above the boarding platform. The protective ring is then placed around the waist of the person. The use of sponge increases the softness of the protective ring when it fits the person, and the use of a stop block reduces the opening between the protective rings. When the protective ring is placed around the waist, the person can hold the handle and press down, so that the force on the protective ring can be transmitted to the movable seat and the sliding seat. According to the person's walking, the person can use the handle to push the protective ring and the sliding seat to move. The sliding seat can slide inside the boarding platform, thus improving the safety of the person when boarding. Attached Figure Description

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as shown in the attached document Figure 1 , Figure 3 and Figure 4 As shown, it includes a boarding platform 5, a stabilizing mechanism 2 and a protective mechanism 13. The stabilizing mechanism 2 includes a tension rod 102 and a base 104. The bottom end of the tension rod 102 is fixedly connected to the base 104. The tension rod 102 and the base 104 are used to improve the stability of the multi-axis linkage of the device, thereby enabling wave compensation of the device.

[0025] The protective mechanism 13 includes a protective ring 136 and a stop block 135. The front and rear surfaces of the protective ring 136 are fixedly connected to the stop block 135. The protective ring 136 and the stop block 135 are used to protect passengers and prevent danger.

[0026] The overall effect of Embodiment 1 is as follows: the extension and retraction of the tension rod 102 allows for height adjustment according to the multi-axis trajectory movement of the device; the base 104 supports the tension rod 102, thereby improving the stability of the device during multi-axis movement; and the protective ring 136 and the stop block 135 can be fitted around the waist of the person boarding, thereby improving the safety of the person during boarding.

[0027] Example 2, as Figure 1 and Figure 3 As shown, the stabilizing mechanism 2 also includes a retractable tube 101. The top end of the retractable tube 101 is movably connected to the lower surface of the boarding platform 5 via a joint. The interior of the retractable tube 101 is slidably connected to the tension rod 102. A counterweight 106 is fixedly connected to the upper surface of the base 104. A connecting tube 103 is fixedly connected to the inner top wall of the base 104. A ball bearing 105 is movably connected to the interior of the connecting tube 103.

[0028] The overall effect of Embodiment 2 is as follows: through the sliding of the contraction tube 101 and the tension rod 102, the weight of the counterweight 106 allows the tension rod 102 to extend from the inside of the contraction tube 101, enabling the base 104 to drive the ball bearing 105 to conform to the deck of the ship. The length of the tension rod 102 can be changed according to the multi-axis motion trajectory of the device. In the absence of external obstruction, the downward pulling force of the counterweight 106 causes the tension rod 102 to extend from the inside of the contraction tube 101, reaching the maximum or equilibrium height of the mechanism. When the mechanism is placed or applied to a concave surface... On an uneven deck, or when the relative position of the deck and the bottom of the mechanism changes due to the rocking of the ship, the ball bearing 105 first contacts the deck. The deck pushes the base 104 upward through the ball bearing 105, forcing the tension rod 102 to slide upward and retract slightly into the contraction tube 101. The tension rod 102 adjusts the extension length in real time according to the dynamic balance between the deck reaction force on the base 104 and the gravity of the counterweight 106, ensuring that the ball bearing 105 always effectively contacts the deck surface, so that the tension rod 102 and the contraction tube 101 can improve the stability of the device during multi-axis movement.

[0029] Example 3, as Figure 1 and Figure 4 As shown, the protective mechanism 13 also includes a sliding seat 131. The rear surface of the sliding seat 131 is movably connected to a movable seat 133 via a bearing. The front surface of the movable seat 133 is fixedly connected to a protective ring 136. The inner wall of the protective ring 136 is provided with a sponge 132. The upper surface of the protective ring 136 is fixedly connected to a handle 134. The upper surface of the boarding platform 5 is fixedly connected to a guardrail 3. The front and rear surfaces of the guardrail 3 are both fixedly connected to a sliding plate 4. The interior of the sliding plate 4 is slidably connected to the sliding seat 131.

[0030] The overall effect of embodiment 3 is as follows: when a person is boarding, the movable connection between the movable seat 133 and the sliding seat 131 allows the movable plate to be moved above the boarding platform 5, and the protective ring 136 is placed around the person's waist. The sponge 132 increases the softness of the protective ring 136 when it fits the person, and the stop block 135 reduces the opening between the protective rings 136. When the protective ring 136 is placed around the person's waist, the person can hold the handle 134 and press down, so that the force on the protective ring 136 can be transmitted to the movable seat 133 and the sliding seat 131. According to the person's walking, the person can use the handle to push the protective ring 136 and the sliding seat 131 to move. The sliding seat 131 can slide inside the boarding platform, thus improving the safety of the person boarding.

[0031] Example 4, as Figures 1-2As shown, a swing seat 8 is fixedly connected to the lower surface of the boarding platform 5. A lifting seat 9 is movably connected to the front surface of the swing seat 8 via a bearing. A support frame 6 is fixedly connected to the upper surface of the lifting seat 9. An electric push rod 7 is movably connected to the inner top wall of the support frame 6 via a bearing. The output end of the electric push rod 7 is movably connected to the side surface of the swing seat 8 via a bearing. A hydraulic cylinder 19 is provided on the lower surface of the lifting seat 9. A rotating seat 11 is fixedly connected to the lower surface of the hydraulic cylinder 19. A translation seat 12 is provided on the lower surface of the rotating seat 11. An internally fixed first motor 17 is connected, and the output end of the first motor 17 is fixedly connected to the bottom end of the translation seat 12. A guide block 16 is slidably connected to the lower surface of the translation seat 12, and an orientation adjustment seat 1 is slidably connected to the lower surface of the guide block 16. A threaded sleeve 10 is fixedly connected to the lower surface of the translation seat 12. A second motor 14 is provided on the front surface of the orientation adjustment seat 1. A lead screw 15 is fixedly connected to the output end of the second motor 14, and the lead screw 15 is threadedly connected to the threaded sleeve 10. Mounting seats 18 are fixedly connected to both sides of the orientation adjustment seat 1.

[0032] The overall effect achieved in Embodiment 4 is as follows: Connecting the electric push rod 7 to an external power source allows the swing seat 8 to swing up and down. Because the two ends of the electric push rod 7 are movable, it can tilt according to the swing amplitude of the swing seat 8. The tilt angle of the boarding platform 5 can be adjusted by the swing of the swing seat 8. The hydraulic cylinder 19 can push the lifting seat 9 up and down, allowing for height adjustment of the boarding platform 5. Connecting both the first motor 17 and the second motor 14 to an external power source allows the first motor to be started. The second motor 14 can drive the rotating seat 11 to rotate. The rotation of the rotating seat 11 can adjust the position of the boarding platform 5. Starting the first motor 17 can drive the lead screw 15 to rotate. The rotation of the lead screw 15 can drive the threaded sleeve 10 to move back and forth. The back and forth movement of the threaded sleeve 10 can drive the translation seat 12 to move back and forth. By using the back and forth movement of the translation seat 12, the rotation of the rotating seat 11, the lifting and lowering of the lifting seat 9, and the swinging of the swinging seat 8, the boarding platform 5 can be adjusted in multiple axes, thereby improving the convenience of boarding.

[0033] The working principle of the entire device is as follows: starting the electric push rod 7 can push the swing seat 8 to swing up and down. The electric push rod 7 is movable at both ends, so the electric push rod 7 can tilt according to the swing amplitude of the swing seat 8. The tilt angle of the boarding platform 5 can be adjusted by the swing of the swing seat 8. The hydraulic cylinder 19 can push the lifting seat 9 to move up and down, so that the height of the boarding platform 5 can be adjusted. Starting the second motor 14 can drive the rotating seat 11 to rotate. The position of the boarding platform 5 can be adjusted by the rotation of the rotating seat 11. Starting the first motor 17 can drive the lead screw 15 to rotate. The rotation of the lead screw 15 can drive the lead sleeve 10 to move back and forth. The back and forth movement of the lead sleeve 10 can drive the translation seat 12 to move back and forth, so that the boarding platform 5 can be adjusted by multi-axis movement.

[0034] By sliding the retraction tube 101 and the tension rod 102, the weight of the counterweight 106 allows the tension rod 102 to extend from the inside of the retraction tube 101. This enables the base 104 to drive the ball bearing 105 to contact the deck of the ship. The ball bearing 105 first contacts the deck, and the deck pushes the base 104 upward through the ball bearing 105, forcing the tension rod 102 to slide upward and retract slightly into the retraction tube 101. The tension rod 102 adjusts its extension length in real time based on the dynamic balance between the deck reaction force on the base 104 and the weight of the counterweight 106, ensuring that the ball bearing 105 is always effectively engaged. When the protective ring 136 is placed on the waist of the person, the sponge 132 can increase the softness of the protective ring 136 when it fits the person, and the stop block 135 can reduce the opening between the protective rings 136. When the protective ring 136 is placed on the waist of the person, the person can hold the handle 134 and press down, so that the force on the protective ring 136 can be transmitted to the movable seat 133 and the sliding seat 131. According to the person's walking, he can use the handle to push the protective ring 136 and the sliding seat 131 to move. The sliding seat 131 can slide inside the skateboard, thereby improving the safety of the person when boarding.
