[0034] This embodiment provides a transport lifting device, such as... Figures 1-3 As shown, the transport lifting device includes a first transport mechanism 1 and a second transport mechanism 2. The first transport mechanism 1 includes a first loading assembly 11, a first lifting assembly 12, and a first traveling assembly 13. The first loading assembly 11 includes a first loading platform 111, which can carry cargo. When the first loading platform 111 is not lifted, its height is a first height. The first lifting assembly 12 is used to drive the first loading platform 111 to the height of the cargo hatch, which is greater than the first height. The first traveling assembly 13 is used to drive the first loading platform 111 to move to the cargo hatch. The second transport mechanism 2 includes a second loading platform 21, a second lifting assembly 22, and a second traveling assembly 23. The second loading platform 21 can carry cargo. The output end of the second lifting assembly 22 is connected to the second loading platform 21, and the second lifting assembly 22 can drive the second loading platform 21 to the first height. The second traveling assembly 23 is used to drive the second lifting assembly 22 to move to the first transport mechanism 1, and the first loading platform 111 can dock with the second loading platform 21.

[0035] The transport lifting device provided in this embodiment, when in use, the second platform 21 of the second transport mechanism 2 carries the goods, the second traveling component 23 drives the second platform 21 to move to the first transport mechanism 1, the second lifting component 22 lifts the second platform 21 to a first height and docks with the first platform 111 of the first transport mechanism 1, and the goods are transferred to the first platform 111; the first traveling component 13 drives the first platform 111 to move to the cargo hold opening, the first lifting component 12 lifts the first platform 111 to the height of the cargo hold opening, and the goods are transferred into the cargo hold. This transport lifting device enables phased transport and lifting of goods, improving the flexibility of transfer. The first loading platform 111 has a relatively large initial height from the ground, while the second loading platform 21 has a low initial height from the ground. Goods can be easily moved onto the second loading platform 21 by manpower. The second loading platform 21 is then lifted to the first height and docked with the first loading platform 111, transferring the goods onto the first loading platform 111. This improves the efficiency of transport lifting operations. When transporting heavy goods, it can reduce manual operation, reduce manpower consumption, avoid accidents, and achieve efficient and safe transport.

[0036] like Figure 4 As shown, the transport lifting device also includes a cargo cart 3, which can carry goods. The cargo cart 3 can be pre-loaded with goods and directly transferred to the second loading platform 21 along with the goods, and then fixed on the second loading platform 21. On the one hand, this greatly saves the time of moving goods one by one to the second loading platform 21, facilitates the overall transfer of goods from the second loading platform 21 to the first loading platform 111, reduces manpower input, lowers labor intensity, and significantly improves cargo loading efficiency. On the other hand, using the cargo cart 3 to load goods can better protect the goods from damage and avoid the collisions caused by handling goods piecemeal.

[0037] like Figures 5-6 As shown, the first loading assembly 11 also includes a support platform 112, a guide rail (not shown), and a slider (not shown). The support platform 112 is connected to the output end of the first lifting assembly 12. The guide rail is fixedly mounted on the support platform 112 and extends horizontally. The slider is slidably mounted on the guide rail, and the first loading platform 111 is connected to the slider. The guide rail extends horizontally, allowing the slider to slide on it, enabling the first loading platform 111 connected to the slider to move and adjust horizontally. On one hand, when docking with the second loading platform 21, fine adjustments can be made through horizontal sliding, allowing for more precise cargo transfer. On the other hand, the horizontal sliding of the first loading platform 111 allows it to extend into the cargo hold, reducing the need for manual labor to move cargo from the first loading platform 111 into the cargo hold, thus improving the efficiency and accuracy of transport lifting operations.

[0038] like Figure 2As shown, the first transport mechanism 1 also includes a telescopic drive member 18 and a first anti-collision member 141. The telescopic drive member 18 is used to drive the first platform 111 to move horizontally relative to the support platform 112. The first anti-collision member 141 is disposed at the front end of the first platform 111. The first anti-collision member 141 is electrically connected to the telescopic drive member 18. The first anti-collision member 141 can detect obstacles in the horizontal direction of the first platform 111 and send a first signal. The telescopic drive member 18 can receive the first signal and stop driving the first platform 111. The telescopic drive 18 can drive the first platform 111 to move horizontally relative to the support platform 112, allowing the first platform 111 to extend deep into the cargo hold, effectively solving the problems of inconvenience and low efficiency in manual handling. The first anti-collision component 141 is located at the front end of the first platform 111, which can detect obstacles in the horizontal direction in the cargo hold and send a first signal, so that the telescopic drive 18 can stop driving the first platform 111 to move horizontally in time, avoiding collision of the first platform 111 in the cargo hold and protecting the safety of equipment and cargo.

[0039] In this embodiment, the telescopic drive 18 can be a cylinder. The piston rod inside the cylinder can reciprocate in the horizontal direction relative to the cylinder body. The cylinder body is fixedly connected to the support platform 112, and the piston rod is connected to the first platform 111. The movement of the piston rod can drive the first platform 111 to move in the horizontal direction relative to the support platform 112.

[0040] In this embodiment, the first platform 111 can move within a range of 0-400mm relative to the support platform 112. This range of movement can be adjusted by changing the size of the first platform 111 and the support platform 112 according to the actual situation, and is not specifically limited here.

[0041] like Figure 2 As shown, the first transport mechanism 1 also includes a second anti-collision member 142. The second anti-collision member 142 is disposed at the lower end of the first loading platform 111 and is electrically connected to the first lifting assembly 12. The second anti-collision member 142 can detect obstacles in the vertical direction of the first loading platform 111 and send a second signal. The first lifting assembly 12 can receive the second signal and stop driving the first loading platform 111. The second anti-collision member 142 is located at the lower end of the first loading platform 111, can detect obstacles in the vertical direction in the cargo hold and send a second signal, causing the first lifting assembly 12 to stop driving the first loading platform 111 to move in the vertical direction, and also prevents the first loading platform 111 from hitting the bottom of the cargo hold during descent, thereby improving the safety and reliability of the operation.

[0042] In this embodiment, both the first anti-collision member 141 and the second anti-collision member 142 are pressure sensors. When the first platform 111 moves towards the cargo hold, if its front end contacts a horizontal obstacle, the first pressure sensor deforms under force, generating an electrical signal as the first signal, which is transmitted to the telescopic drive member 18, and the drive of the first platform 111 stops. When the lower end of the first platform 111 contacts a vertical obstacle or the bottom of the cargo hold during the lifting process, the second pressure sensor generates a second signal, which is transmitted to the first lifting assembly 12 and stops the drive of the first platform 111. This design can effectively avoid collisions, protect the safety of the first platform 111 and the cargo, and improve the safety and stability of the transportation lifting operation.

[0043] In other embodiments, the first anti-collision member 141 and the second anti-collision member 142 can both be ultrasonic sensors. During the operation of the first transport mechanism 1, the first anti-collision member 141 at the front end of the first platform 111 is a first ultrasonic sensor, and the second anti-collision member 142 at the lower end of the first platform 111 is a second ultrasonic sensor. The first ultrasonic sensor continuously emits ultrasonic waves in the horizontal direction and calculates the distance between the front end of the first platform 111 and obstacles in the horizontal direction through the reflected waves. When the distance is less than a set threshold, a first signal is emitted to stop the telescopic drive member 18 from driving the first platform 111. The second ultrasonic sensor continuously emits ultrasonic waves in the vertical direction and calculates the distance between the lower end of the first platform 111 and obstacles in the vertical direction through the reflected waves. When the distance is less than a set threshold, a second signal is emitted to stop the first lifting assembly 12 from driving the first platform 111. This non-contact detection method is fast-responding, highly accurate, and can provide early warnings to avoid collisions, ensuring the safety of the transport lifting device and the goods, and significantly improving the safety and efficiency of transport lifting operations.

[0044] like Figures 5-6As shown, the first lifting assembly 12 includes a first scissor lift 121, a first drive member 122, a first fixed frame 123, and a second fixed frame (not shown). The first fixed frame 123 is fixedly connected to the support platform 112, and the second fixed frame is fixedly connected to the first traveling assembly 13. The two ends of the first scissor lift 121 are movably connected to the first fixed frame 123 and the second fixed frame, respectively. The first drive member 122 is used to drive the first scissor lift 121 to extend or retract, so as to drive the first platform 111 to rise or fall. Since one end of the first scissor lift 121 is movably connected to the first fixed frame 123 which is fixedly connected to the support platform 112, and the other end is movably connected to the second fixed frame which is fixedly connected to the first traveling assembly 13, during operation, the first driving member 122 drives the first scissor lift 121 to extend and push the first loading platform 111 to rise; when retracting, the first driving member 122 drives the first loading platform 111 to descend. This design makes the lifting process stable and reliable, the scissor structure can withstand a large weight, realize the lifting and lowering of heavy goods, and occupy little space, efficiently realize height adjustment in a limited space, and meet diverse transportation lifting needs.

[0045] like Figures 5-6 As shown, the first scissor lift 121 includes multiple first scissor arms 1211. Each first scissor arm 1211 includes two first rods 12111 and a pivot 12112. The pivot 12112 passes through the two center portions of the two first rods 12111, allowing the two first rods 12111 to rotate around the pivot 12112. The two ends of the two first rods 12111 of any first scissor arm 1211 are rotatably connected to the two ends of the two first rods 12111 of the adjacent first scissor arm 1211. The first fixed frame 123 is provided with a first track groove 1231 and a first lug (not shown). A first sliding member (not shown) is slidably disposed in the first track groove 1231. One of the first rods 12111 of the first scissor arm 1211 near the first platform 111 is rotatably connected to the first lug, and the other first rod 12111 is rotatably connected to the first sliding member. The second fixed frame is provided with a second track groove (not shown) and a second lug (not shown). A second sliding member (not shown) is slidably installed in the second track groove. One of the first rods 12111 of the first scissor arm 1211 near the first traveling assembly 13 is rotatably connected to the second lug, and the other first rod 12111 is rotatably connected to the second sliding member. This design ensures stable lifting and lowering of the first scissor lift 121, effectively improving the stability of the lifting and lowering of the first platform 111 and meeting the requirements of different working heights.

[0046] Specifically, when the first scissor lift 121 extends or retracts, the two first rods 12111 of any first scissor arm 1211 rotate around the pivot 12112, and the clamping angle of the two first rods 12111 changes. The two first rods 12111 of the first scissor arm 1211 closer to the first platform 111 rotate with the first lug and the first sliding member respectively, and the first sliding member slides in the first track groove 1231; the two first rods 12111 of the first scissor arm 1211 closer to the first traveling assembly 13 rotate with the second lug and the second sliding member respectively, and the second sliding member slides in the second track groove.

[0047] like Figures 5-6 As shown, in this embodiment, the output end of the first drive member 122 is rotatably connected to the first scissor arm 1211 near the first platform 111, and the first drive member 122 is also rotatably connected to the first scissor arm 1211 near the first traveling assembly 13. The first drive member 122 can drive the first scissor lift 121 to extend or retract. The first drive member 122 directly drives the first scissor lift 121 to move, resulting in a simple drive structure, rapid response, and precise and efficient control of the lifting height of the first platform 111.

[0048] In this embodiment, the first driving component 122 can be a hydraulic cylinder. The hydraulic rod inside the hydraulic cylinder can reciprocate relative to the hydraulic cylinder body. The hydraulic rod is rotatably connected to the first scissor arm 1211 near the first platform 111. The hydraulic cylinder body is rotatably connected to the first scissor arm 1211 near the first traveling component 13. The movement of the hydraulic rod drives the first scissor frame 121 to extend or retract.

[0049] In other embodiments, the first driving member 122 may also be a cylinder, and the piston rod inside the cylinder can reciprocate relative to the cylinder body. The piston rod is rotatably connected to the first scissor arm 1211 near the first platform 111, and the cylinder body is rotatably connected to the first scissor arm 1211 near the first walking assembly 13. The movement of the piston rod drives the first scissor frame 121 to extend or retract.

[0050] like Figure 2 As shown, in this embodiment, the first lifting assembly 12 further includes a first limiting member 124, which is disposed in the second track groove and can limit the movement range of the second sliding member. The first limiting member 124 disposed in the second track groove can limit the movement range of the second sliding member, thereby adapting the maximum lifting height of the first platform 111 to the height of the cargo hold opening, preventing the first scissor lift 121 from overextending, effectively preventing the upper end of the first platform 111 or the cargo from hitting the upper wall of the cargo hold opening, preventing damage to the transport lifting device and the cargo hold, and ensuring the safety and stability of the operation.

[0051] In other embodiments, the first limiting member 124 is disposed within the first track groove 1231, which can limit the range of motion of the first sliding member. The first limiting member 124 disposed within the first track groove 1231 can limit the range of motion of the first sliding member, thereby adapting the maximum lifting height of the first platform 111 to the height of the cargo hold opening, preventing the first scissor lift 121 from overextending, effectively preventing the upper end of the first platform 111 or the cargo from hitting the upper wall of the cargo hold opening, preventing damage to the transport lifting device and the cargo hold, and ensuring the safety and stability of the operation.

[0052] like Figures 2-4 As shown, the first transport mechanism 1 further includes a first flap 15, which is rotatably connected to the end of the first loading platform 111; the second transport mechanism 2 further includes a second flap 24, which is rotatably connected to the end of the second loading platform 21. The overlapping connection of the first flap 15 and the second flap 24 enables efficient cargo transfer, significantly improving the operational efficiency of transporting cargo to the cargo hold.

[0053] In summary, the operation process of the transport lifting device is roughly as follows:

[0054] (1) Rotate the second flap 24 so that the second flap 24 overlaps with the ground at a slope, so that the cargo vehicle 3 and the transported goods are transported together to the second platform 21, and fix the cargo vehicle 3 on the second platform 21. Then retract the second flap 24 and the second walking component 23 drives the second platform 21 to the first transport mechanism 1.

[0055] (2) The second lifting component 22 drives the second platform 21 to rise to the first height, the second platform 21 docks with the first platform 111, the first flip plate 15 and the second flip plate 24 are rotated, the first flip plate 15 and the second flip plate 24 are connected to each other, so as to facilitate the transfer of goods on the second platform 21 to the first platform 111, and the cargo vehicle 3 is fixed on the first platform 111. The first flip plate 15 and the second flip plate 24 are retracted.

[0056] (3) The first traveling component 13 transports the first platform 111 to the vicinity of the cargo hold opening, and the first lifting component 12 lifts the first platform 111 to the height of the cargo hold opening and adjusts the distance between the first platform 111 and the cargo hold opening so that the lower end of the first platform 111 leaves a gap with the bottom wall of the cargo hold.

[0057] (4) The telescopic drive 18 drives the first loading platform 111 to move relative to the support platform 112 so that the first loading platform 111 extends into the interior of the cargo hold, and rotates the first flap 15 so that the first flap 15 overlaps with the bottom wall of the cargo hold, transporting the cargo vehicle 3 and the transported goods together into the cargo hold.

[0058] In this embodiment, both the first flap 15 and the second flap 24 are damped slow-descent flaps. In other embodiments, the first flap 15 and the second flap 24 can also be electrically telescopic flaps, manually flaps, etc., which are not specifically limited here.

[0059] like Figures 1-6 As shown, the first transport mechanism 1 also includes a first guardrail 16, which is arranged around the circumference of the first loading platform 111; the second transport mechanism 2 also includes a second guardrail 25, which is arranged around the circumference of the second loading platform 21. The first guardrail 16, arranged around the circumference of the first loading platform 111, effectively prevents goods from falling off the platform due to shaking or bumping during the lifting and moving of the first loading platform 111, thus avoiding damage to the goods and harm to surrounding personnel and equipment. The second guardrail 25, arranged around the circumference of the second loading platform 21, provides protection for the goods before they are transported to dock with the first loading platform 111, reducing the risk of falling.

[0060] In this embodiment, the first transport mechanism 1 further includes a third guardrail 19, which is arranged circumferentially around the support platform 112. When the first loading platform 111 slides along the guide rail, it can prevent the first loading platform 111 from detaching from the support platform 112 due to improper operation.

[0061] In this embodiment, the telescopic drive 18 can also be a hydraulic cylinder. The hydraulic rod inside the hydraulic cylinder can reciprocate in the horizontal direction relative to the hydraulic cylinder body. The hydraulic cylinder body is fixedly connected to the third fence 19, and the hydraulic rod is connected to the first fence 16. The movement of the hydraulic rod can drive the first fence 16 to move in the horizontal direction relative to the third fence 19, that is, drive the first platform 111 to move in the horizontal direction relative to the support platform 112.

[0062] In this embodiment, the first walking assembly 13 includes a chassis 131, a drive wheel 132, a support member 133, and a walking control member 134. The chassis 131 is fixedly connected to the second fixed frame. The drive wheel 132 is rotatably mounted on the bottom of the chassis 131 to provide driving power for the first transport mechanism 1. One end of the support member 133 is movably connected to the chassis 131. During transportation, the support member 133 plays a balancing role. When the first loading platform 111 reaches the cargo hold opening for unloading, the other end of the support member 133 can support the ground, enhancing the stability of the first transport mechanism 1. The walking control member 134 is electrically connected to the drive wheel 132. The operator can electrically control the walking control member 134 to control the movement of the drive wheel 132, or the operator can manually rotate the walking control member 134 to drive the drive wheel 132 to move, so as to precisely control the direction and speed of the first transport mechanism 1.

[0063] In this embodiment, the support member 133 is a heavy metal block. In other embodiments, the support member 133 can also be a suction cup, etc., and no specific limitation is made here.

[0064] like Figure 2 As shown, in this embodiment, the first transport mechanism 1 further includes an electrical control cabinet 17, which is mounted on the chassis 131. The electrical control cabinet 17 serves as the power distribution and control center for the first transport mechanism 1. The electrical control cabinet 17 is electrically connected to the first lifting assembly 12, providing power to the first lifting assembly 12 to achieve the lifting action of the first platform 111. The electrical control cabinet 17 is also electrically connected to the first walking assembly 13, providing power to the first walking assembly 13 to achieve the walking action, ensuring the normal operation of the first transport mechanism 1.

[0065] like Figure 1 , Figures 3-4 As shown, the second traveling assembly 23 includes a base frame 231, traveling wheels 232, and a support arm 233. The traveling wheels 232 are rotatably mounted on the bottom of the base frame 231, providing mobility for the second transport mechanism 2. The support arm 233 is movably connected to the base frame 231 and connected to the traveling wheels 232. The support arm 233 can adjust the traveling angle of the traveling wheels 232. On the one hand, when the road surface is uneven during transport, the support arm 233 can flexibly change its angle to ensure that the traveling wheels 232 are always in effective contact with the ground, preventing the traveling wheels 232 from slipping and maintaining the stable forward movement of the second transport mechanism 2. On the other hand, when carrying heavy goods, the support arm 233 enhances the stability of the connection between the base frame 231 and the traveling wheels 232, distributes the weight of the goods, and avoids damage to the traveling wheels 232 or the base frame 231 due to uneven force, ensuring that the second transport mechanism 2 transports goods smoothly.

[0066] like Figure 1 and Figure 3 As shown, in this embodiment, the second transport mechanism 2 also includes a power distribution box 26. The power distribution box 26 is the power distribution and control center of the second transport mechanism 2. The power distribution box 26 is electrically connected to the second lifting component 22 and provides power to the second lifting component 22 to realize the lifting action of the second platform 21. The power distribution box 26 is also electrically connected to the second walking component 23 and provides power to the second walking component 23 to realize the walking action, ensuring that the second transport mechanism 2 can operate normally.

[0067] like Figure 1 , Figures 3-4As shown, the second lifting assembly 22 includes a second scissor arm 221, a third fixed frame 222, a fourth fixed frame (not shown), and a second drive member 223. The third fixed frame 222 is fixedly connected to the second platform 21, and the fourth fixed member is fixedly connected to the base frame 231. The second scissor arm 221 includes two second rods 2211 and a pivot 2212. The pivot 2212 passes through the two center portions of the two second rods 2211, and the two second rods 2211 can rotate around the pivot 2212. The third fixed frame 222 is provided with a third track groove 2221 and a third lug. A third sliding member (not shown) is slidably provided in the third track groove 2221. The first end of one of the second rods 2211 of the second scissor arm 221 is rotatably connected to the third lug, and the first end of the other second rod 2211 is rotatably connected to the third sliding member. The fourth fixed frame is provided with a fourth track groove (not shown) and a fourth support lug (not shown). A fourth sliding member (not shown) is slidably arranged in the fourth track groove. The second end of one of the second rods 2211 of the second scissor arm 221 is rotatably connected to the fourth support lug, and the second end of the other second rod 2211 is rotatably connected to the fourth sliding member. The output end of the second drive member 223 is rotatably connected to one of the second rods 2211, and the main body of the second drive member 223 is rotatably connected to the base frame 231.

[0068] In this embodiment, the second driving component 223 is a hydraulic cylinder. The hydraulic rod inside the hydraulic cylinder can reciprocate relative to the main body of the hydraulic cylinder. The hydraulic rod is rotatably connected to one of the second rods 2211, and the main body of the hydraulic cylinder is rotatably connected to the base frame 231. In other embodiments, the second driving component 223 can also be a pneumatic cylinder, which is not specifically limited here.

[0069] Specifically, when the second drive unit 223 is activated, the output end of the second drive unit 223 drives one of the second rods 2211 that is rotatably connected to it to move. The two second rods 2211 rotate around the pivot 2212, and the included angle between the two second rods 2211 changes, so as to extend or retract the second scissor arm 221, so as to make the second platform 21 rise and fall smoothly, and ensure the safety and efficiency of cargo transportation and transfer.
