Description

Technical Field

[0001] This utility model relates to the field of board storage technology, and in particular to a sunken lifting platform with a board alignment structure. Background Technology

[0002] Boards are a common building material and industrial raw material. They are flat materials made from various raw materials through specific processing techniques. They have a certain thickness and a large surface area. Because boards have a large area, they occupy a lot of space. In order to save the floor space of boards, a storage tank is opened underground to store the boards. In order to facilitate the loading and unloading of boards, a ground-mounted lifting platform with a board alignment structure is needed.

[0003] A search revealed Chinese patent publication number CN222807030U, which discloses a lifting platform comprising: a base; a lifting platform surface that can be raised and lowered relative to the base, the lifting platform surface having a storage groove; and a support plate that is slidably disposed in the storage groove and can slide backward to a retracted state and forward to a pulled-out state, the upper surface of the support plate having multiple sorting slots; wherein, when in the retracted state, the support plate is stored inside the lifting platform surface; when in the pulled-out state, the support plate is at least partially located outside the lifting platform surface, exposing the sorting slots. This application provides a sorting and storage function, making it easy for operators to quickly find tools without occupying the operating area of ​​the lifting platform surface, ensuring smooth assembly operations. However, when supporting sheet metal, since the sheet metal needs to be stacked one by one, it is necessary to ensure that the sheet metal is aligned. This lifting platform can only raise and lower, without a corresponding alignment function. In actual use, workers need to carefully align the stacked sheet metal, reducing work efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a ground-sinking lifting platform with an alignment plate structure, which aims to improve the problem in the prior art where the lifting platform can only lift and cannot limit the plate, resulting in difficulty in aligning the plate.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a ground-sinking lifting platform with an alignment plate structure, comprising a base plate and a top plate, wherein a lifting assembly is provided between the base plate and the top plate, an alignment mechanism is provided on the top of the top plate, fixing assemblies are provided on the front and rear sides of the outer wall of the base plate, and a buffer mechanism is provided on the top of the base plate; the alignment mechanism includes multiple alignment rods, the bottom ends of which are fixedly connected to the front top of the top of the top plate, and extension rods are slidably connected to the top of the inner walls of the multiple alignment rods; multiple threaded holes are equidistantly provided on the upper and lower sides of the front ends of the outer walls of the multiple extension rods. Each of the outer walls of the first alignment rod is threaded with a bolt, and the rear ends of the bolts are threaded to the corresponding threaded holes. Two alignment rods are fixedly connected to the top right side of the top plate. Each of the two alignment rods is slidably connected to an extension rod. Multiple threaded holes are provided on the upper and lower sides of the right side of the outer wall of each extension rod. Each of the two alignment rods is threaded with a bolt, and the left ends of the bolts are threaded to the corresponding threaded holes. Two connecting rods are fixedly connected between adjacent alignment rods and between adjacent alignment rods.

[0006] The above technical solution achieves the lifting and lowering of the top plate, providing different height positions for the panels. The alignment mechanism is used to accurately align the panels. Multiple alignment rods are fixed at their bottom ends to the front top of the top plate, and extension rods are slidably connected to their inner walls. By rotating bolts, which engage with threaded holes, the extension length of the extension rods within the alignment rods can be adjusted. Similarly, the top of the second alignment rod on the right side of the top plate is slidably connected to the second extension rod. The length of the second extension rod is adjusted by bolts and threaded holes. When placing the panels, the front end of the panels contacts the first alignment rod and the first extension rod, and the right end contacts the second alignment rod and the second extension rod. The alignment rods and extension rods limit the panels in the front-back and left-right directions. At the same time, connecting rod 1 connects to adjacent alignment rod 1, and connecting rod 2 connects to adjacent alignment rod 2, enhancing the overall stability of the alignment mechanism, ensuring the alignment effect, and ensuring that the panels are accurately placed on the top plate, providing a good foundation for subsequent operations. The fixing components on the front and rear sides of the outer wall of the bottom plate are used to fix the panels and prevent them from shifting during lifting and lowering. The buffer mechanism at the top of the bottom plate acts as a buffer when the top plate descends, preventing damage to the equipment and the panels.

[0007] As a further description of the above technical solution:

[0008] The buffer mechanism includes multiple hollow tubes, the bottom ends of which are fixedly connected to the four corners of the top of the base plate. Each hollow tube has a sliding rod slidably connected to its inner wall top. Each sliding rod has a limit ring fixedly connected to its top. Each limit ring has a spring fixedly connected to its bottom. The bottom ends of each spring are fixedly connected to the base plate.

[0009] Through the above technical solution: when the top plate descends, it first contacts the limiting ring. As the top plate continues to descend, the limiting ring is subjected to downward pressure. Since the top of the sliding rod is fixed to the limiting ring, and the sliding rod can slide on the top of the hollow tube, the limiting ring drives the sliding rod to slide downward inside the hollow tube. At the same time, the limiting ring compresses the spring connected at the bottom. The spring is elastic and undergoes elastic deformation after being compressed, thereby generating an upward counterforce. This counterforce increases as the spring is compressed, thus buffering the impact of the top plate descending and preventing damage to the lifting platform and placed items caused by the sudden descent of the top plate. The hollow tube is fixed at the four corners of the top of the base plate, providing stable support for the entire buffering process. The sliding of the sliding rod inside the hollow tube ensures the stability and guidance of the buffering.

[0010] As a further description of the above technical solution:

[0011] The lifting assembly includes two rotating seats 1. The bottoms of the two rotating seats 1 are respectively fixedly connected to the front and rear sides of the top left end of the base plate. A support frame 1 is rotatably connected between the two adjacent rotating seats 1. A support frame 2 is rotatably connected to the outer wall of the support frame 1. Pulleys are rotatably connected to the front and rear sides of the bottom of the outer wall of the support frame 2. Rollers are rotatably connected to the front and rear sides of the right end of the support frame 1. Rotating seats 2 are fixedly connected to the front and rear sides of the bottom left end of the top plate. The adjacent sides of the two rotating seats 2 are respectively rotatably connected to the front and rear sides of the left end of the support frame 2. A rotating rod is fixedly rotatably connected to the right side of the inner wall of the support frame 2. A hydraulic rod is fixedly connected to the left side of the outer wall of the rotating rod. A fixed plate is fixedly connected to the middle of the inner wall of the support frame 1. The left end of the hydraulic rod is rotatably connected to the fixed plate.

[0012] Through the above technical solution: one end of the hydraulic rod is connected to the rotating rod, and the other end is connected to the fixed plate in the middle of the inner wall of the support frame one. When the hydraulic rod extends or retracts, it pushes the rotating rod. Because the rotating rod is fixedly and rotatably connected to the right side of the inner wall of the support frame two, the support frame two is caused to rotate about the connection point with the support frame one. The support frame one is rotatably connected to the front and rear sides of the top left end of the base plate through the rotating seats one at both ends, serving as the basis for support and rotation. The pulley at the bottom of the support frame two slides on the base plate, and the roller at the right end of the support frame one slides on the bottom of the top plate, reducing friction and assisting rotation. The rotating seats two at the front and rear sides of the bottom left end of the top plate are rotatably connected to the front and rear sides of the left end of the support frame two, so that the rotation of the support frame two drives the top plate to rise or fall, realizing the height adjustment function of the lifting platform.

[0013] As a further description of the above technical solution:

[0014] The fixing assembly includes two positioning plates. The outer walls of the two positioning plates are respectively fixedly connected to the front and rear sides of the outer wall of the base plate. Multiple positioning bolts are threaded at equal intervals on the top left and right sides of the two positioning plates. Multiple reinforcing blocks are fixedly connected at equal intervals on the top left and right sides of the outer walls of the two positioning plates. The adjacent sides of the multiple reinforcing blocks are fixedly connected to the base plate.

[0015] The above technical solution involves: a fixing component to securely fix the base plate to the ground; two positioning plates connected to the front and rear sides of the outer wall of the base plate; and positioning bolts on the top left and right sides of the positioning plates that can be screwed into the ground by rotation, using the friction between them and the ground to pull the base plate from the front and back, preventing it from moving forward or backward. Reinforcing blocks are equidistantly connected to the top left and right sides of the outer wall of the positioning plates and connected to the base plate, enhancing the connection strength between the positioning plates and the base plate, preventing the positioning plates from loosening during the fixing process, and ensuring that the base plate is stably fixed to the ground.

[0016] As a further description of the above technical solution:

[0017] Each of the multiple alignment rods 1 and 2 has a limiting groove on its outer wall, and each of the multiple extension rods 1 and 2 has a limiting block fixedly connected to its outer wall. The multiple limiting grooves are slidably connected to the corresponding limiting blocks.

[0018] The above technical solution involves: a fixing component to securely fix the base plate to the ground; two positioning plates connected to the front and rear sides of the outer wall of the base plate; and positioning bolts on the top left and right sides of the positioning plates that can be screwed into the ground by rotation, using the friction between them and the ground to pull the base plate from the front and back, preventing it from moving forward or backward. Reinforcing blocks are equidistantly connected to the top left and right sides of the outer wall of the positioning plates and connected to the base plate, enhancing the connection strength between the positioning plates and the base plate, preventing the positioning plates from loosening during the fixing process, and ensuring that the base plate is stably fixed to the ground.

[0019] As a further description of the above technical solution:

[0020] The top right end of the base plate has sliding grooves on both the front and rear sides, and the two pulleys are slidably connected to the corresponding sliding grooves.

[0021] Through the above technical solution: the top right end of the base plate has a sliding groove that works with a pulley. The pulley slides in the sliding groove, which guides the movement of the second support frame and helps the lifting assembly to achieve smooth lifting of the top plate.

[0022] As a further description of the above technical solution:

[0023] Multiple limiting plates are fixedly connected to the bottom right side of the top plate, and the multiple limiting plates are slidably connected to the top of the support frame.

[0024] The above technical solution involves a limiting plate on the right side of the bottom of the top plate slidingly connected to the top of the support frame, which restricts the vertical displacement of the support frame and ensures a stable connection between the top plate and the support frame during lifting and lowering.

[0025] As a further description of the above technical solution:

[0026] Protective plates are fixedly connected to the front and rear sides of the right end of the outer wall of the base plate, and the adjacent sides of the two protective plates are slidably connected to the corresponding pulleys.

[0027] Through the above technical solution: the protective plate on the right end of the outer wall of the base plate is slidably connected to the pulley. The protective plate can block debris, prevent collisions, ensure the normal sliding of the pulley, and maintain the stable operation of the lifting component.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the hydraulic rod in the lifting assembly pushes the fixed plate, causing the first support frame and the second support frame to rotate relative to each other around the first rotating seat. With the help of rollers and pulleys, the top plate is lifted and lowered. At the same time, the extension rod one and the alignment rod one, and the extension rod two and the alignment rod two in the alignment mechanism can be adjusted in height through bolts and threaded holes. The alignment rod and the connecting rod limit the position of the plate. In this way, the problem of the existing lifting platform being able to only lift and lower but not limit the position of the plate, which leads to the difficulty of alignment, is solved, and the accuracy of plate placement and work efficiency are improved.

[0030] 2. In this utility model, the hollow tube is fixed to the four corners of the base plate to provide support. The top plate descends and squeezes the limiting ring, which drives the slide rod to slide inside the hollow tube. At the same time, the spring is compressed, and the spring generates an upward reverse force to buffer the impact force of the top plate descending, avoiding damage to the lifting platform and the items on the platform. The sliding of the slide rod inside the hollow tube ensures buffering stability, effectively solving the problem that existing lifting platforms are prone to large impacts when descending, and improving the safety and stability of the equipment.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 3 , Figure 5 and Figure 6This utility model provides an embodiment of a ground-sinking lifting platform with an alignment plate structure, comprising a base plate 1 and a top plate 4. The base plate 1 serves as the foundation support for the entire device, providing an installation base for other components. The top plate 4 is used to support the plates that need to be lifted and aligned. A lifting assembly 5 is provided between the base plate 1 and the top plate 4 to realize the lifting action of the top plate 4 to meet the working requirements of different heights. An alignment mechanism 2 is provided on the top of the top plate 4. Fixing assemblies 6 are provided on the front and rear sides of the outer wall of the base plate 1. A buffer mechanism 3 is provided on the top of the base plate 1 to buffer the impact force generated when the top plate 4 descends, protecting the equipment and the plates. The alignment mechanism 2 includes multiple alignment rods 201, multiple... The bottom ends of the alignment rods 201 are all fixedly connected to the top front side of the top plate 4, used for aligning and limiting the plate from the front. Extension rods 202 are slidably connected to the top of the inner walls of the alignment rods 201, allowing them to slide on the top of the inner walls of the alignment rods 201. The extension length can be adjusted according to different plate lengths, increasing the applicability of the alignment mechanism 2. Multiple threaded holes 203 are equidistantly opened on the upper and lower sides of the front ends of the outer walls of the multiple extension rods 202. Bolts 204 are threadedly connected to the top front sides of the outer walls of the multiple alignment rods 201. The rear ends of the bolts 204 are threadedly connected to the corresponding threaded holes 203. The threaded holes 203 are located on the upper and lower sides of the front ends of the outer walls of the extension rods 202, used to cooperate with the bolts 204 to achieve alignment. The extension rod 202 is fixed in position. Two alignment rods 205 are fixedly connected to the top right side of the top plate 4, cooperating with alignment rod 201 to align and limit the plate from the right. Extension rods 206 are slidably connected to the top of each alignment rod 205, allowing them to slide on top of the alignment rods 205 and adjusting the alignment position according to the plate length. Multiple threaded holes 207 are provided on the upper and lower right sides of the outer wall of each extension rod 206. Bolts 208 are threadedly connected to the top right side of the outer wall of each alignment rod 205. The left ends of the two bolts 208 are threaded into the corresponding threaded holes 207. The threaded holes 207 are located on the upper and lower right sides of the outer wall of the extension rod 206, cooperating with the bolts 208 to achieve... To fix the position of extension rod 206, two connecting rods 209 are fixedly connected between adjacent alignment rods 201 to enhance the structural stability between alignment rods 201 and make them more secure when aligning plates. Two connecting rods 210 are fixedly connected between adjacent alignment rods 205. Limiting grooves 7 are provided on the outer walls of multiple alignment rods 201 and alignment rods 205 to cooperate with limiting blocks 8 to restrict the movement direction of extension rods 202 and 206. Limiting blocks 8 are fixedly connected to the outer walls of multiple extension rods 202 and 206. The multiple limiting grooves 7 are slidably connected to the corresponding limiting blocks 8 to ensure that extension rods 202 and 206 slide in the specified direction.The lifting assembly 5 includes two rotating seats 501. The bottoms of the two rotating seats 501 are fixedly connected to the front and rear sides of the top left end of the base plate 1, respectively, providing rotational support points for the support frame 502. The support frame 502 is rotatably connected between adjacent rotating seats 501. When the lifting assembly 5 is working, it rotates around the rotating seats 501 to realize the lifting and lowering of the top plate 4. The outer wall of the support frame 502 is rotatably connected to the support frame 503. The support frame 503 is rotatably connected to the outer wall of the support frame 502. The two cooperate with each other and change the overall height through relative rotation, thereby driving the top plate 4 to lift and lower. The front and rear sides of the bottom of the outer wall of the support frame 503 are rotatably connected to pulleys 504. When the support frame 503 moves, the pulleys 504 roll on the base plate 1, reducing the moving friction and making the movement of the support frame 503 smoother. The front and rear sides of the right end of the support frame 502 are rotatably connected to rollers 505. The rollers 505 roll on the bottom of the top plate 4 to assist in the movement of the support frame 502. The support frame 502 rotates to ensure the stability of the lifting and lowering process of the top plate 4. The bottom left end of the top plate 4 is fixedly connected to the front and rear sides of the rotating seat 506, which provides the connection point between the support frame 503 and the top plate 4, so that the support frame 503 can drive the top plate 4 to lift and lower. The adjacent sides of the two rotating seats 506 are respectively rotatably connected to the front and rear sides of the left end of the support frame 503. The inner right side of the support frame 503 is fixedly rotatably connected to the rotating rod 507, which provides the connection base for the hydraulic rod 508. At the same time, the hydraulic rod 508 drives the support frame 503 to rotate. The outer left side of the rotating rod 507 is fixedly connected to the hydraulic rod 508. The middle of the inner wall of the support frame 502 is fixedly connected to the fixing plate 509. The left end of the hydraulic rod 508 is rotatably connected to the fixing plate 509. Through the extension and retraction of the hydraulic rod 508, the rotating rod 507 is pushed or pulled, thereby controlling the relative rotation of the support frame 502 and the support frame 503, so as to realize the lifting and lowering of the top plate 4.

[0041] Specifically, the base plate 1 and the top plate 4 serve as the basic structure. The base plate 1 provides support, and the top plate 4 is used to support the plates. The lifting assembly 5 enables the lifting and lowering of the top plate 4. Two rotating seats 501 are fixed to the front and rear sides of the top left end of the base plate 1. The support frame 502 is rotatably connected between the two and is rotatably connected to the outer wall of the support frame 503. The pulley 504 at the bottom of the support frame 503 slides on the base plate 1, and the roller 505 at the right end of the support frame 502 slides at the bottom of the top plate 4, providing movement assistance for the rotation of the support frame and the lifting and lowering of the top plate. The rotating seat 506 at the bottom of the top plate 4 is rotatably connected to the left end of the support frame 503, so that the top plate and the support frame are linked. The rotating rod 507 is fixed to the right side of the inner wall of the support frame 503. One end of the hydraulic rod 508 is connected to the rotating rod 507, and the other end is connected to the inner wall of the support frame 502. The fixed plate 509 is rotatably connected, and the hydraulic rod 508 extends and retracts to change the distance between the two support frames, thereby realizing the lifting and lowering of the top plate. The alignment mechanism 2 is used for aligning the plates. Multiple alignment rods 1 201 on the left side of the top plate 4 and two alignment rods 205 on the right side are slidably connected to extension rods 1 202 and 206 on their inner walls, respectively. The height of the extension rods is adjusted by the threaded connection of bolt 1 204 to threaded hole 1 203 and bolt 2 208 to threaded hole 207. Connecting rod 1 209 and connecting rod 2 210 are respectively connected to adjacent alignment rods 1 201 and 205 to enhance structural stability. The sliding connection between the limiting groove 7 and the limiting block 8 ensures the stability of the extension rods when they slide, and facilitates the limiting and alignment of the plates by the alignment rods. The buffer mechanism 3 plays a buffering role when the top plate descends, reducing the impact.

[0042] Reference Figure 1 and Figure 2 The buffer mechanism 3 includes multiple hollow tubes 301. The bottom ends of the multiple hollow tubes 301 are fixedly connected to the four corners of the top of the base plate 1, providing a stable support foundation for the entire buffer mechanism 3. The top of the inner wall of each of the multiple hollow tubes 301 is slidably connected to a slide rod 302. The slide rod 302 is slidably connected to the top of the inner wall of the hollow tube 301. Its function is to slide up and down inside the hollow tube 301 to guide the direction of the buffering action. The top of each of the multiple slide rods 302 is fixedly connected to a limit ring 303 to limit the radial displacement of the spring 304 and transmit the pressure of the top plate 4 falling. The bottom of each of the multiple limit rings 303 is fixedly connected to a spring 304, which uses its own elastic deformation to generate buffering force and reduce the impact force of the top plate 4 falling. The bottom ends of each of the multiple springs 304 are fixedly connected to the base plate 1.

[0043] Specifically, the bottom ends of multiple hollow tubes 301 are fixed at the four corners of the top of the base plate 1, providing a stable support structure for the entire buffer mechanism 3 and limiting the sliding direction of the slide rod 302. The top of the slide rod 302 is fixedly connected to the limiting ring 303, and the slide rod 302 slides on the top of the inner wall of the hollow tube 301, so that the limiting ring 303 can move up and down along the axial direction of the hollow tube 301 with the slide rod 302. The limiting ring 303 not only connects the slide rod 302 and the spring 304, but also limits the radial displacement of the spring 304 to a certain extent, ensuring that the spring 304 is subjected to uniform force. The top end of the spring 304 is fixed to the bottom of the limiting ring 303, and the bottom end is connected to the base plate 1. When the top plate 4 descends and contacts the limiting ring 303 and continues to press down, the spring 304 is compressed, and its elastic deformation generates an upward elastic force, thereby slowing down the descent speed of the top plate 4, realizing the buffer function, and preventing the top plate 4 from descending too quickly and causing damage to the equipment and items.

[0044] Reference Figure 1 and Figure 2 The fixing component 6 includes two positioning plates 601. The outer walls of the two positioning plates 601 are fixedly connected to the front and rear sides of the outer wall of the base plate 1, respectively, for positioning the base plate 1 from both sides and providing basic support for the fixing operation. Multiple positioning bolts 602 are threaded at equal intervals on the top left and right sides of the two positioning plates 601, so that the positioning plates 601 can be stably installed on the ground. Multiple reinforcing blocks 603 are fixedly connected at equal intervals on the top left and right sides of the outer walls of the two positioning plates 601. The adjacent side of the multiple reinforcing blocks 603 is fixedly connected to the base plate 1 to enhance the connection strength between the positioning plates 601 and the base plate 1 and prevent the positioning plates 601 from loosening during the fixing of objects.

[0045] Specifically, two positioning plates 601 are fixed to the front and rear sides of the outer wall of the base plate 1, respectively, providing a basic framework for the fixing operation. Multiple positioning bolts 602 on the top left and right sides of the positioning plate 601 can be rotated downwards. When it is necessary to fix the base plate 1, the positioning bolts 602 are rotated to make them abut into the mounting holes drilled in the ground, and the base plate 1 is fixed to the ground by friction. The reinforcing blocks 603 are fixed at equal intervals on the top left and right sides of the outer wall of the positioning plate 601 and connected to the base plate 1, which enhances the stability of the connection between the positioning plate 601 and the base plate 1, prevents the positioning plate 601 from shaking or shifting during the fixing of items, and ensures reliable fixing effect.

[0046] Reference Figure 3 , Figure 4 and Figure 6The top right end of the base plate 1 is provided with sliding grooves 9 on both the front and rear sides. Two pulleys 504 are slidably connected to the corresponding sliding grooves 9, providing a specific sliding track for the pulleys 504 so that they can move stably along the track. Multiple limiting plates 10 are fixedly connected to the bottom right side of the top plate 4 to limit the vertical displacement of the support frame 502 and prevent the support frame 502 from moving excessively and detaching from the connection with the top plate 4. The multiple limiting plates 10 are slidably connected to the top of the support frame 502. The slidable connection between the limiting plates 10 and the top of the support frame 502 ensures the normal rotation of the support frame 502 and the stability of the connection between the top plate 4 and the support frame 502 during the lifting and lowering of the top plate 4. Protective plates 11 are fixedly connected to the front and rear sides of the right end of the outer wall of the base plate 1. The adjacent side of the two protective plates 11 is slidably connected to the corresponding pulleys 504, which protects the pulleys 504 and prevents external debris from interfering with the normal sliding of the pulleys 504.

[0047] Specifically, the slide groove 9 is slidably connected to the two pulleys 504 at the bottom of the second support frame 503. When the lifting assembly 5 is working and the second support frame 503 moves, the pulleys 504 slide in the slide groove 9. The slide groove 9 provides a precise movement trajectory for the pulleys 504, guiding the second support frame 503 to move smoothly and ensuring the straightness and stability of the lifting process of the top plate 4. Multiple limit plates 10 are slidably connected to the top of the first support frame 502. This design limits the excessive displacement of the first support frame 502 in the vertical direction, preventing it from losing its connection with the top plate 4. This ensures that the first support frame 502 can always provide stable support for the top plate 4 during the lifting process, and also helps the top plate 4 to maintain a horizontal state and avoid tilting. The protective plate 11 is slidably connected to the corresponding pulleys 504 on its adjacent side. The protective plate 11 protects the pulleys 504, preventing external debris from interfering with the normal sliding of the pulleys 504 in the slide groove 9. At the same time, it blocks accidental collisions to a certain extent from damaging the pulleys 504 and the second support frame 503, ensuring the stable operation of the lifting platform.

[0048] Working principle: First, the hydraulic rod 508 in the lifting assembly 5 is activated. After the hydraulic rod 508 starts working, it pushes the fixed plate 509, increasing the distance between the fixed plate 509 and the rotating rod 507. This action causes the support frame 1 502 and the support frame 2 503 to rotate relative to each other. During the rotation, the support frame 1 502 rotates around the connection point with the rotating seat 1 501. At the same time, the roller 505 slides on the bottom of the top plate 4, and the pulley 504 slides on the top of the base plate 1. Under the coordinated action of these components, the support frame 1 502 and the support frame 2 503 together lift the top plate 4 upward, realizing the lifting action of the lifting platform. When it is necessary to place the plate, the alignment mechanism 2 comes into play. Since the extension rod 1 202 can slide within the alignment rod 1 201, and the extension rod 2 206 can slide within the alignment rod 2 205, the adjustment bolt 1 20... 4. The engagement of threaded hole 203 and bolt 208 with threaded hole 207 allows for adjustment of the height of extension rod 202 and extension rod 206. When placing the plate, the operator only needs to contact the front end of the plate with the rear end of alignment rod 201 and the right end of the plate with the left end of alignment rod 205. In this way, the plate can be restricted by alignment rod 201, alignment rod 205, and connecting rods 209 and 210, thus achieving plate alignment. At the same time, the sliding connection between the limiting groove 7 and the limiting block 8 ensures the stability of extension rod 202 and extension rod 206 during the sliding process, preventing them from shaking and affecting the plate alignment effect. This lifting platform effectively solves the problem in the prior art where the lifting platform can only lift and cannot limit the plate, leading to difficulties in plate alignment.

[0049] Furthermore, as the top plate 4 descends, the buffer mechanism 3 begins to function. The buffer mechanism 3 consists of multiple hollow tubes 301, a sliding rod 302, a limiting ring 303, and a spring 304. The bottom ends of the multiple hollow tubes 301 are firmly fixed to the four corners of the top of the bottom plate 1. As the top plate 4 gradually descends, after reaching a specific moving height, the top plate 4 first contacts the limiting ring 303. At this time, the force of the top plate 4 continuing to descend acts on the component limiting ring 303, causing the component limiting ring 303 to be compressed downwards. Since the top of the sliding rod 302 is fixedly connected to the component limiting ring 303, and the sliding rod 302 is slidably connected to the top of the inner wall of the hollow tube 301, the downward movement of the limiting ring 303 drives the sliding rod 302 to slide downwards inside the hollow tube 301. At the same time, the limiting ring 303... During the descent, the spring 304 fixed at the bottom is compressed. According to the characteristics of the spring 304, the spring 304 will undergo elastic deformation after being compressed, which will provide an upward counterforce to the limiting ring 303. This counterforce gradually increases as the spring 304 is compressed. In this process, the counterforce provided by the spring 304 effectively buffers the impact force of the descent of the top plate 4, preventing the sudden descent of the top plate 4 from causing damage to the entire lifting platform and the items placed on the top plate 4. The sliding of the slide rod 302 in the hollow tube 301 not only provides guidance for the up and down movement of the limiting ring 303, but also ensures the stability of the buffering process, so that the buffering effect can be continuously and effectively exerted, ensuring the stability and safety of the lifting platform during the descent of the top plate 4.
