[0040] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0041] The embodiment of the present utility model provides a scissor lift platform, which can quickly realize the lifting process of the load platform, and provide a large hydrophilic platform for the drowning person, improving the efficiency and success rate of water rescue.

[0042] See Figures 1 to 9 , the scissor lift platform provided by the embodiment of the present utility model includes a scissor assembly 1, a flipping assembly 2, and a load platform 3. Among them, two groups of scissor assemblies 1 are arranged at intervals along the first straight line direction. The scissor assembly 1 includes a support base 11, a first driving part 12, and a plurality of scissor units 13 connected end to end from top to bottom. The scissor unit 13 located at the uppermost layer is connected to the support base 11, and the first driving part 12 can drive the scissor unit 13 to extend downward or contract upward on the support base 11; the flipping assembly 2 includes a base 21 and a second driving part 22. The base 21 is arranged on the hull 100, the support base 11 is rotatably connected to the base 21, and the second driving part 22 can drive the support base 11 to flip between the deployed position and the retracted position. When the support base 11 is in the deployed position, the support base 11 protrudes horizontally from the side wall of the hull 100; when the support base 11 is in the retracted position, the support base 11 is vertically arranged and parallel to the side wall of the hull 100; one scissor assembly 1 is arranged on each side of the load platform 3, and both sides of the load platform 3 are respectively connected to the scissor unit 13 located at the lowermost layer.

[0043] For the scissor lift platform proposed by the present utility model, when water rescue is required, the second driving part 22 drives the support base 11 to flip to the deployed position. After the support base 11 flips stably, the first driving part 12 drives the scissor unit 13 to extend downward, so that the carrying platform 3 is transferred onto the water surface, thereby providing a hydrophilic platform for deck rescue personnel to facilitate the rescue of drowning persons. When water rescue is not required, the second driving part 22 drives the scissor unit 13 to contract upward on the support base 11, and then the second driving part 22 drives the support base 11 to flip to the retracted position, thus completing the storage of the scissor lift platform, making the scissor lift platform not protrude from the hull 100, improving the overall aesthetics of the hull 100, and having a high space utilization rate.

[0044] The scissor lift platform proposed by the present utility model uses the first driving part 12 to drive the extension and contraction of the scissor unit 13, realizing the flexible lifting of the carrying platform 3 in the vertical direction, and can quickly and accurately move the carrying platform 3 to an appropriate height to efficiently rescue drowning persons at different water depths, solving the problem in the prior art that the release time of rescue equipment is long, resulting in the missed best rescue opportunity. Secondly, the setting of the flipping assembly 2 drives the support base 11 to flip between the deployed position and the retracted position through the second driving part 22. When in the deployed position, the support base 11 can be ensured to be horizontal for normal rescue work, and when in the retracted position, the support base 11 is vertically arranged and parallel to the side wall of the hull 100, saving space and also facilitating the driving and docking of the ship in the non-rescue state, improving the maneuverability and applicability of the ship. Moreover, the carrying platform 3 is connected to the lowermost scissor unit 13. Since both sides of the carrying platform 3 are rigidly connected to the scissor unit 13, the carrying platform 3 has a high load-bearing capacity, ensuring that the carrying platform 3 will not rotate under the surge, improving the stability of the carrying platform 3, and being able to stably carry drowning persons, and can effectively rescue unconscious or seriously injured drowning persons who have lost their mobility, making up for the defect in the prior art that relies on the self-awareness and mobility of the rescued person.

[0045] For the specific structure of the scissor assembly 1, refer to Figure 1 and Figure 7, the scissor unit 13 includes two scissor arms 131. The two scissor arms 131 are arranged crosswise and rotatably connected. The crosswise design of the two scissor arms 131 makes the lifting process more stable and reliable, and can ensure that the carrying platform 3 remains stable during the lifting process. In this embodiment, the two scissor arms 131 of the same scissor unit 13 cross and rotatably connect with each other, and the two scissor arms 131 of adjacent two scissor units 13 rotatably connect, forming a coherent linkage mechanism. When the first driving part 12 drives the scissor arm 131 located at the top layer to move, through the linkage mechanism formed by the rotational connection, it drives the connected scissor arms 131 to extend or contract in sequence. This enhances the integrity and coordination of the entire scissor lift platform, enabling the lifting action to proceed smoothly. Among the scissor units 13 located at the top layer, one of the scissor arms 131 is fixedly connected to the support base 11, and the other scissor arm 131 is slidably connected to the support base 11. The first driving part 12 can drive the other scissor arm 131 to slide on the support base 11 along the second straight line direction. Such a design can precisely control the extension and contraction of the scissor unit 13 and achieve precise adjustment of the height of the carrying platform 3.

[0046] It can be understood that the specific number of the scissor units 13 is not limited herein and is adaptively selected according to the height of the actual hull 100.

[0047] Specifically, the scissor arm 131 includes two scissor rods 1311. The two scissor rods 1311 are arranged at intervals along the first straight line direction. By setting the structure of the two scissor rods 1311, the strength and stability of the scissor arm 131 are further enhanced. During the working process of the scissor lift platform, it can better bear the weight of the carrying platform 3 and the fallen personnel, ensuring the safety and reliability of the entire rescue process. The spaced arrangement of the two scissor rods 1311 makes the force transmission more uniform and stable, reducing the risk of deformation or damage caused by local force concentration, and effectively extending the service life of the scissor lift platform. The two ends of the two scissor rods 1311 are connected by a connecting shaft 1312, thus ensuring the synchronous movement of the two scissor rods 1311 and the coordination of the movement of the scissor assembly 1.

[0048] In other embodiments, the scissor arm 131 may also be provided with three or four scissor rods 1311 arranged at intervals and sequentially penetrated by the same connecting shaft 1312, which is not limited herein.

[0049] Specifically, a pin shaft is penetrated through the center of the two crosswise arranged scissor rods 1311, and the two scissor rods 1311 can rotate around the pin shaft. The two scissor rods 1311 between adjacent two scissor units 13 are also rotatably connected by a pin shaft. In other embodiments, the connection between the two scissor rods 1311 may also be a hinge, etc., which is not limited herein.

[0050] See Figure 7 , more specifically, the first driving part 12 is selected as the first hydraulic cylinder, and the telescopic end of the first hydraulic cylinder is connected to another scissors arm 131 located at the topmost layer. The first hydraulic cylinder has powerful driving force and precise control performance, and can stably and efficiently drive the scissors arm 131 to perform stretching and contracting actions, ensuring that the carrying platform 3 can quickly and accurately reach the required position, improving the timeliness and accuracy of rescue. In addition, the telescopic action of the hydraulic cylinder is relatively stable, which can keep the scissor lift platform in good stability during the lifting process, reducing the risk of secondary injury to the rescued personnel caused by jitter or instability, and also being beneficial to ensuring the safety of the rescue personnel during the operation process.

[0051] During use, one of the scissors arms 131 is fixed to the support base 11. By contracting the telescopic end of the first hydraulic cylinder, the other scissors arm 131 is driven to move closer to the fixed scissors arm 131. Since the two scissors arms 131 are cross - arranged and fixed in the middle by a pin shaft, when the two scissors arms 131 approach each other, the relative width of the two scissors arms 131 decreases and the length of the corresponding scissors unit 13 increases. Since the scissors arms 131 of multiple scissors units 13 are rotationally connected by pin shafts, when the top - most scissors arm 131 moves, each scissors arm 131 connected to it is driven to move synchronously in turn, thus realizing the overall stretching effect of the scissors unit 13 to achieve the lowering effect of the carrying platform 3. When the telescopic end of the first hydraulic cylinder extends, it is the reverse movement of the above - mentioned movement, which will not be elaborated here.

[0052] See Figure 1 , in order to improve the stability of the scissors assembly 1 during the movement process, the scissors assembly 1 includes a connecting seat 14. The connecting seat 14 is arranged on the scissors unit 13 located at the bottom - most layer. A positioning slider 15 is arranged at one end of the connecting seat 14 close to the hull 100. A positioning groove 101 is formed on the hull 100. The positioning groove 101 extends in the vertical direction. The positioning slider 15 is clamped in the positioning groove 101 and is slidably connected to the positioning groove 101. Through the cooperation of the positioning slider 15 and the positioning groove 101, it can play a certain guiding role in the movement process of the clamping assembly, thus ensuring that the scissors assembly 1 moves stably along the established vertical direction during stretching and contracting, avoiding unstable situations such as shaking and deviation, thereby improving the accuracy and reliability of the lifting of the entire carrying platform 3 and ensuring the smooth progress of the rescue work.

[0053] See Figure 9, more specifically, guiding protrusions 151 are provided on the side walls of the positioning slider 15, and corresponding guiding sliding rails 102 are provided on the inner walls of the positioning grooves 101. The guiding protrusions 151 are slidably connected to the guiding sliding rails 102, further strengthening the guiding property of the scissors assembly 1 during the lifting process. The precise cooperation between the guiding protrusions 151 and the guiding sliding rails 102 can ensure that the scissors assembly 1 moves strictly along the predetermined straight track, reducing the possible skew or jamming phenomena, making the lifting action of the scissors unit 13 smoother and more stable, thereby improving the efficiency and quality of the rescue operation. In addition, the sliding connection mode between the guiding protrusions 151 and the guiding sliding rails 102 helps to reduce the frictional resistance, improves the smoothness of the movement of the scissors unit 13, reduces the load of the first driving part 12, extends the service life of the equipment, and also reduces the energy consumption.

[0054] Therefore, through the cooperation of the positioning slider 15 and the positioning groove 101 and the cooperation of the guiding protrusions 151 and the guiding sliding rails 102, double guiding of the scissors unit 13 during the lifting process is achieved, ensuring the stability of the scissors unit 13 during the movement process, guaranteeing the normal operation of the bearing platform 3, reducing the probability of faults occurring, and improving the rescue rate.

[0055] See Figure 3 and Figure 8 , regarding the specific structure of the flipping assembly 2. The second driving part 22 selects a second hydraulic cylinder. The support base 11 includes an integrally formed support section 111 and a connection section 112, enhancing the overall strength and durability of the support base 11. The support section 111 and the connection section 112 are arranged in an L shape to facilitate the force-bearing flipping of the support base 11. The support section 111 is connected to the scissors unit 13, the bottom of the connection section 112 is hinged to the base 21, and the telescopic end of the second hydraulic cylinder is connected to the connection section 112. The second hydraulic cylinder can drive the support base 11 to flip along the vertical direction.

[0056] During use, when it is necessary to flip the support base 11 to the retracted position, drive the telescopic end of the second hydraulic cylinder to extend downward, thereby pushing the connection section 112 to flip downward through the second hydraulic cylinder. Since the bottom of the connection section 112 is hinged to the base 21, through the lever principle, drive the support section 111 connected to the other end of the connection seat 14 to flip upward, thereby flipping the support base 11 to the retracted position and synchronously driving the scissors assembly 1 retracted on the support section 111 to also flip to the retracted position; when it is necessary to flip the support base 11 to the deployed position, drive the telescopic end of the second hydraulic cylinder to contract upward, and the principle is the same as the above process and will not be elaborated here.

[0057] In this embodiment, the deployed position is parallel to the top surface of the hull 100, the retracted position is perpendicular to the top surface of the hull 100 and parallel to the side wall of the hull 100, and the included angle between the deployed position and the retracted position is 90 degrees. In other embodiments, the included angle between the deployed position and the retracted position can also be 120 degrees, 180 degrees, etc., which is not limited herein.

[0058] It can be understood that the above-mentioned first hydraulic cylinder and second hydraulic cylinder are both common mechanical devices in the field, and their working principles and specific structures are not described herein. In other embodiments, the first driving part 12 and the second driving part 22 can also be selected from devices such as air cylinders and electric pumps, which are not limited herein.

[0059] In order to prevent rainwater, sundries, etc. from eroding, protective covers are provided on both the first hydraulic cylinder and the second hydraulic cylinder to protect the first hydraulic cylinder and the second hydraulic cylinder and improve their service life.

[0060] See Figure 1 , in order to further improve the rescue effect of the loading platform 3 on the fallen personnel. A support railing 4 is detachably provided on the side of the loading platform 3 away from the hull 100. The support railing 4 includes two side rods 41. The two side rods 41 are arranged at intervals along the first straight line direction. The side rods 41 extend vertically downward and protrude from the bottom of the loading platform 3, so that a part of the support railing 4 can enter the water, facilitating the fallen personnel or the rescue personnel to hold underwater. A plurality of cross rods 42 are arranged at intervals between the two side rods 41. Through the cooperation of the cross rods 42 and the side rods 41, a ladder structure is formed, and the cross rods 42 provide a force application point, so that the fallen personnel or the rescue personnel can step on or hold the cross rods 42 to climb onto the loading platform 3.

[0061] Specifically, since the loading platform 3 is hydrophilic for operation, in order to prevent water from accumulating on the loading platform 3, which is not only easy to rust the equipment but also easy to make people slip under their feet. Therefore, a plurality of through holes 31 are opened on the loading platform 3, and the through holes 31 penetrate the loading platform 3 in the vertical direction. Through the setting of the through holes 31, the accumulated water on the loading platform 3 can be quickly and effectively drained away, avoiding the occurrence of water accumulation, thereby reducing the risk of equipment rust due to long-term water accumulation, extending the service life of the equipment, and also avoiding the loading platform 3 from slipping.

[0062] In addition, a non-slip mat is laid on the loading platform 3. In this embodiment, the non-slip mat is made of a rubber mat. In other embodiments, the non-slip mat can also be a frosted mat, etc., which is not described herein.

[0063] More specifically, the bearing platform 3 includes a plurality of transverse rods and a plurality of longitudinal rods, and the plurality of transverse rods and the plurality of longitudinal rods are arranged in an alternating manner to enclose a through hole 31. On the one hand, by forming the bearing platform 3 in a mesh shape with the transverse rods and longitudinal rods, the overall weight of the bearing platform 3 can be effectively reduced, making it more lightweight and flexible during use, facilitating operation and movement, and reducing energy consumption and the load on the driving device. On the other hand, when the bearing platform 3 rises from the water, the through hole 31 allows water to quickly drain out, greatly improving the drainage efficiency and avoiding the additional burden caused by water residue on the bearing platform 3 or affecting subsequent operations.

[0064] For the scissor lift platform provided by the embodiment of the present utility model, when water rescue is required, first, the telescopic end of the second hydraulic cylinder is driven to contract upward, so as to push the connecting section 112 to turn upward through the second hydraulic cylinder. Since the bottom of the connecting section 112 is hinged to the base 21, by the lever principle, the support section 111 connected to the other end of the connecting seat 14 is driven to turn downward, so as to turn the support base 11 to the unfolded position, making the support base 11 parallel to the top surface of the hull 100, and synchronously driving the scissor assembly 1 retracted on the support section 111 to also turn to the unfolded position; after the support base 11 is turned, the second hydraulic cylinder is locked. Then, the telescopic end of the first hydraulic cylinder is driven to contract, driving the other scissor arm 131 to move closer to the fixed scissor arm 131. Since the two scissor arms 131 are cross - arranged and fixed in the middle by a pin shaft, when the two scissor arms 131 approach each other, the relative width of the two scissor arms 131 decreases and the length of the corresponding scissor unit 13 increases. Since the scissor arms 131 of the plurality of scissor units 13 are rotatably connected by pin shafts, when the top - most scissor arm 131 moves, each scissor arm 131 connected to it is driven to move synchronously in sequence, so as to realize the overall downward extension of the scissor unit 13, thereby driving the bearing platform 3 to descend to the target position, making the bearing platform 3 be transferred onto the water surface, providing a hydrophilic platform for the deck rescue personnel to facilitate their rescue of the drowning personnel.

[0065] When water rescue is not required, first drive the telescopic end of the first hydraulic cylinder to extend, driving the other scissor arm 131 to move away from the fixed scissor arm 131. Since the two scissor arms 131 are cross - arranged and fixed in the middle by a pin shaft, when the two scissor arms 131 move away from each other, the relative width of the two scissor arms 131 increases, causing the length of the corresponding scissor unit 13 to decrease. Since the scissor arms 131 of multiple scissor units 13 are rotatably connected by pin shafts, when the top - layer scissor arm 131 moves, each scissor arm 131 connected to it is driven to move synchronously in turn, thus realizing the overall upward contraction of the scissor unit 13, driving the carrying platform 3 to contract onto the support base 11. After the scissor assembly 1 is retracted, drive the telescopic end of the second hydraulic cylinder to extend downward, thereby pushing the connecting section 112 to flip downward through the second hydraulic cylinder. Since the bottom of the connecting section 112 is hinged to the base 21, by the lever principle, drive the support section 111 connected to the other end of the connecting seat 14 to flip upward, thus flipping the support base 11 to the retracted position, making the support base 11 parallel to the side wall of the hull 100, and synchronously driving the scissor assembly 1 retracted on the support section 111 to also flip to the deployed position; thus completing the storage of the scissor - type lifting platform, so that the scissor - type lifting platform does not protrude from the hull 100, facilitating the navigation of the hull 100.

[0066] The above - mentioned embodiments only illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above - mentioned embodiments. Without departing from the spirit and scope of the present invention, there are various changes and modifications to the present invention, and these changes and modifications all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
