Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) take-off and landing platforms, and in particular to a vehicle-mounted UAV take-off and landing platform that can stably operate in a complex environment. Background Art

[0002] As we all know, with the rapid development of drone technology, it has been widely used in many fields such as aerial photography, surveying and mapping, inspection, rescue, etc. In actual operations, drones are often required to be quickly deployed and operate stably in different complex environments. The vehicle-mounted drone take-off and landing platform, as a flexible mobile take-off and landing solution, has received more and more attention.

[0003] However, the existing vehicle-mounted UAV take-off and landing platforms have some shortcomings. On the one hand, when the transport vehicle is on the ground with a certain angle, the angle between the take-off and landing platform and the horizontal plane will be larger, which makes it difficult for the UAV to remain stable during take-off and landing, increases the risk of take-off and landing, and may even cause damage to the UAV; on the other hand, under some severe weather conditions, such as strong winds, the existing take-off and landing platforms lack effective protection and stability measures, and cannot provide a suitable take-off and landing and operating environment for the UAV, affecting the operation effect and safety of the UAV. Therefore, a vehicle-mounted UAV take-off and landing platform that can operate stably in complex environments is proposed to meet the needs of stable take-off and landing, operation and flexible deployment of UAVs in various complex environments. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the present invention provides a vehicle-mounted UAV take-off and landing platform that can operate stably in complex environments. The vehicle-mounted UAV take-off and landing platform has the advantages of being able to provide stable take-off and landing conditions and operation guarantees for UAVs in complex environments, and effectively protecting the UAVs so that they can still operate normally under the influence of various adverse factors.

[0006] (II) Technical solution

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: a vehicle-mounted UAV take-off and landing platform that can stably operate in a complex environment, comprising a platform frame, a support structure is arranged at the bottom of the platform frame, a support platform is bolted to the top of the platform frame, and a stabilizing structure is arranged on the top of the support platform;

[0008] The stabilizing structure comprises a windproof barrier, the windproof barrier is rectangular and bolted to the surface of the platform frame, a traction assembly is arranged inside the windproof barrier, the traction assembly is arranged on the top of the supporting platform, and the bottom of the traction assembly extends to the inside of the platform frame;

[0009] The traction assembly includes a guide plate, which is arranged on the top of the support platform, and a connecting shaft passes through the inside of the guide plate, the bottom of the connecting shaft is rotatably connected to a support block, the surface of the support block is sleeved with an elastic sheet, and a locking block is welded on the top of the elastic sheet, two locking sheets are welded on the surface of the locking block, and the locking sheet is in contact with the side close to the guide plate, and the connecting shaft is rotatably connected to the locking block.

[0010] By adopting the above technical solution, through the setting of a stable structure, the windproof barrier can effectively resist the interference of strong winds on the take-off and landing of the UAV, and create a relatively stable take-off and landing environment for the UAV. When the UAV needs to be towed, it is connected to the UAV through structures such as locking blocks and connecting shafts. Therefore, in the initial stage of the UAV take-off and landing, the guide disk is gradually released or tightened, thereby transmitting the traction force to the UAV. When the UAV takes off and lands smoothly, the locking block and locking plate are separated from the guide disk to achieve traction assistance for the UAV take-off and landing process, helping the UAV to overcome adverse factors such as wind and take off and land smoothly.

[0011] The present invention is further configured as follows: the top of the guide disk is configured as a cone, and the locking block is configured as a cone as a whole, the bottom of the support block is bolted with a guide needle, and the top of the guide disk is annularly provided with a plurality of guide grooves used in conjunction with the guide needle.

[0012] By adopting the above technical solution, the top of the guide disk is conical and the locking block is conical as a whole. This shape design enables the locking block to better cooperate with the guide disk when the traction assembly is working. When the drone needs to be towed, more precise guidance and positioning can be achieved through the contact between the conical surfaces of the two, ensuring the accuracy of the traction direction. By setting the further cooperation between the guide needle and the guide groove, during the traction process, the guide needle slides in the guide groove, which helps to accurately control the connection between the locking block and the guide disk and ensure the stability of the drone's take-off and landing.

[0013] The present invention is further configured as follows: a plurality of rotating parts are arranged in a ring shape on the top of the surface of the connecting shaft, and a side of the rotating part close to the locking block is rotatably connected thereto.

[0014] By adopting the above technical solution, the locking block and the connecting shaft can be rotatably connected by setting a rotating part. Therefore, the rotation of the connecting shaft can drive several locking blocks with the elastic sheet as a fulcrum, so that the locking blocks are close to or away from the guide disk, thereby realizing or releasing the connection between the locking sheet and the guide disk, thereby realizing the take-off and landing release and reception of the drone.

[0015] The present invention is further configured as follows: an electric winch and a guide frame are bolted to both sides of the platform frame, a steel cable is wound around the surface of the electric winch, and one end of the steel cable is passed around the guide frame and connected to the guide disc.

[0016] By adopting the above technical solution, an electric winch and a guide frame are set up. When the drone needs to be towed, the electric winch is started and the steel cable begins to be retracted and released according to the instructions of the control system. As the electric winch rotates, the steel cable is gradually released or tightened, driving the guide plate to move accordingly, and then the traction force is transmitted to the drone through other components in the traction assembly, thereby achieving traction assistance for the drone's take-off and landing process, helping the drone to overcome adverse factors such as wind and take off and land smoothly.

[0017] The present invention is further configured as follows: both sides of the top of the support platform are bolted with fixed shells, and the interior of the fixed shells is bolted with hydraulic rods, the top of the hydraulic rods is bolted with connecting blocks, and the connecting blocks are bolted to the guide plate on one side thereof.

[0018] By adopting the above technical solution and setting structures such as a fixed shell, when the guide plate moves, the hydraulic rod will be driven to extend and retract through the connecting block, thereby limiting the moving trajectory of the guide plate and making it move smoothly.

[0019] The present invention is further configured as follows: guide rods are passed through the front and rear sides of the connecting block, and the top and bottom of the guide rods are connected to the inner wall of the fixed shell, and a tension spring is sleeved on the surface of the guide rod, and the tension spring is connected to the fixed shell on one side close to the inner wall of the fixed shell.

[0020] By adopting the above technical solution, by setting a guide rod and a tension spring, the guide rod can limit the moving trajectory of the connecting block, further improving the stability of the guide plate, and the tension spring buffers the movement of the connecting block by releasing or absorbing elastic potential energy, maintaining the smooth movement of the connecting block, thereby ensuring the smooth towing operation of the towing assembly on the drone.

[0021] The present invention is further configured as follows: the windproof barrier includes two fixed blocks, the fixed blocks are connected to the platform frame on one side close to the platform frame, a rotating shaft is rotatably connected between the opposite sides of the two fixed blocks, and a synchronization block is sleeved on the surface of the rotating shaft, a windproof plate is bolted to the top of the synchronization block, and a plurality of through holes are opened inside the windproof plate, guide blades are rotatably connected inside the through holes, the guide blades on both sides are symmetrically arranged, and the two guide blades opposite to each other in the middle are symmetrically arranged.

[0022] By adopting the above technical solution, a windproof barrier is set up, and the opening and closing angle of the windproof plate can be adjusted through the connection between the rotating shaft and the synchronization block, so that the windproof plate can block the direct impact of strong winds on the take-off and landing area of ​​the drone, and reduce the interference of wind on the drone. At the same time, the through holes opened inside the windproof plate and the rotatably connected guide blades can reasonably guide the airflow passing through the windproof barrier. The guide blades on both sides and the middle are symmetrically arranged, so that the airflow can be evenly guided and distributed when passing through the windproof plate, which not only ensures the windproof effect, but also maintains the air circulation in the platform to a certain extent, providing a relatively stable and well-ventilated take-off and landing environment for the drone.

[0023] The present invention is further configured as follows: the supporting structure includes a mounting seat, the four corners of the top of the mounting seat are bolted with adjustment components, the top of the adjustment component is bolted with a movable frame, and the movable frame is bolted to the platform frame, a movable rod is suspended at the bottom of the platform frame, and a heavy hammer is sleeved on the surface of the movable rod, a push plate is arranged in an annular shape on the surface of the heavy hammer, and the push plate is rotatably connected to the adjusting component at one side thereof, and an elastic block is bolted between opposite sides of two adjacent push plates.

[0024] By adopting the above technical solution and setting up a supporting structure, when the transport vehicle stops on the ground with a certain angle, the bottom end of the weight will tilt toward the lower side under the action of gravity, so that the corresponding push plate of the weight tilts and moves with the tilt of the weight, and the push plate applies a force to the adjustment component, so that the adjustment component will move accordingly under the action of this force, so that the adjustment component automatically lifts the inclined part of the platform frame, thereby realizing automatic adjustment of the angle between the take-off and landing platform and the horizontal plane and ensuring the balance of the platform. Through the above-mentioned adaptive adjustment process, the entire supporting structure can maintain the balance of the platform, and ensure that the platform remains stable even when the ground conditions change or the platform is disturbed by external forces, thereby ensuring the safety of the take-off and landing of the drone.

[0025] The present invention is further configured as follows: the adjusting assembly includes a fixed cylinder, the fixed cylinder is bolted to the top of the mounting seat, and the fixed cylinder is slidably connected to a lifting rod, the bottom of the lifting rod is bolted to a connecting rod, and the bottom of the connecting rod is bolted to the inner wall of the fixed cylinder and is sleeved with a push plate, the surface of the connecting rod is sleeved with a first return spring, and the first return spring is respectively connected to the lifting rod and the push plate on one side close to the two, one side of the fixed cylinder is connected to a connecting pipe, and the other end of the connecting pipe is connected to a storage cylinder, a pressure plate is slidably arranged inside the storage cylinder, and a second return spring is arranged between the pressure plate and the inner wall of the storage cylinder, the other side of the pressure plate is bolted to a push rod, and the side of the push rod close to the push plate is rotatably connected to it, and oil is filled between the pressure plate and the inner wall of the storage cylinder and between the push plate and the inner wall of the fixed cylinder.

[0026] By adopting the above technical solution and setting an adjustment component, when the heavy hammer applies force to a certain push plate, the push plate will push the corresponding push rod and pressure plate to move in the storage cylinder and compress the second return spring, thereby squeezing the oil in the storage cylinder and the connecting pipe into the fixed cylinder, so that the oil in the fixed cylinder is also further squeezed, thereby causing the push plate to push the connecting rod and the lifting rod to move upward, and causing the first return spring to contract, thereby automatically lifting the inclined part of the platform frame, realizing automatic adjustment of the angle between the lifting and lowering platform and the horizontal plane and ensuring the balance of the platform, and when the platform frame is in a horizontal position, the heavy hammer will release the squeezing of the push plate under the action of gravity, so that the oil can flow back to the storage cylinder and the push plate can be reset through the elasticity of the first return spring and the second return spring, so as to facilitate the next adjustment work.

[0027] The present invention is further configured as follows: a positioning block is slidably provided at the bottom of the platform frame, and the side of the positioning block close to the weight is in contact with it, a screw block is bolted to the top of the positioning block, and a screw rod passes through the internal thread of the screw block, and the screw rod is rotatably connected to the bottom of the platform frame.

[0028] By adopting the above technical solution, by setting the positioning block, the screw block and the screw rod, the position of the weight can be limited when there is no need to adjust the platform frame, thereby avoiding the synchronous swinging of the weight with the movement of the transport vehicle.

[0029] (III) Beneficial effects

[0030] Compared with the prior art, the present invention provides a vehicle-mounted UAV take-off and landing platform that can stably operate in complex environments, and has the following beneficial effects:

[0031] The vehicle-mounted UAV take-off and landing platform that operates stably in a complex environment can effectively resist the interference of strong winds on the take-off and landing of the UAV by setting a windproof barrier in the stable structure, creating a relatively stable take-off and landing environment for the UAV. At the same time, the traction component arranged inside can provide auxiliary traction for the take-off and landing of the UAV when necessary, such as helping the UAV to take off or land more smoothly in windy weather, overcoming the adverse effects of wind, and further enhancing the stability and safety of the UAV's take-off and landing under severe weather conditions. The windproof barrier can block most of the strong winds and reduce the direct impact of the wind on the UAV; the traction component can flexibly adjust the traction force and direction of the UAV according to the real-time wind conditions, ensuring that the UAV can take off and land as far as possible according to the predetermined trajectory under various wind conditions, and the support structure can automatically adjust its own state to keep the angle between the take-off and landing platform and the horizontal plane as small as possible, effectively solving the problem that the existing platform has too large an angle with the horizontal plane in this case, resulting in unstable take-off and landing of the UAV, providing a relatively stable take-off and landing plane for the UAV, and reducing the risk of take-off and landing.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example 1

[0043] See also Figure 1-5 , a vehicle-mounted UAV take-off and landing platform that can stably operate in a complex environment, comprising a platform frame 1, a support platform 3 is bolted to the top of the platform frame 1, and a stabilizing structure 4 is arranged on the top of the support platform 3;

[0044] The stabilizing structure 4 includes a windproof barrier 41, which is rectangular and bolted to the surface of the platform frame 1. A traction assembly 42 is arranged inside the windproof barrier 41. The traction assembly 42 is arranged on the top of the supporting platform 3, and the bottom of the traction assembly 42 extends to the inside of the platform frame 1.

[0045] The traction assembly 42 includes a guide plate 421, which is arranged on the top of the support platform 3, and a connecting shaft 422 runs through the inside of the guide plate 421, and the bottom of the connecting shaft 422 is rotatably connected to a support block 423, and an elastic sheet 424 is sleeved on the surface of the support block 423, and a locking block 425 is welded on the top of the elastic sheet 424, and two locking sheets 426 are welded on the surface of the locking block 425, and the locking sheet 426 is in contact with the side close to the guide plate 421, and the connecting shaft 422 is rotatably connected to the locking block 425. By setting a stable structure 4, the windscreen The barrier 41 can effectively resist the interference of strong wind on the take-off and landing of the UAV, and create a relatively stable take-off and landing environment for the UAV. When the UAV needs to be towed, it is connected to the UAV through structures such as the locking block 425 and the connecting shaft 422. Therefore, in the initial stage of the UAV take-off and landing, the guide disk 421 is gradually released or tightened, thereby transmitting the traction force to the UAV. When the UAV takes off and lands smoothly, the locking block 425 and the locking plate 426 are separated from the guide disk 421 to achieve traction assistance for the UAV take-off and landing process, helping the UAV to overcome adverse factors such as wind and take off and land smoothly.

[0046] Among them, the top of the guide disk 421 is set in a conical surface, and the locking block 425 is set in a conical shape as a whole. The bottom of the support block 423 is bolted with a guide needle 5, and the top of the guide disk 421 is annularly provided with a plurality of guide grooves 6 used in conjunction with the guide needle 5. The top of the guide disk 421 is set in a conical surface and the locking block 425 is conical as a whole. This shape design enables the locking block 425 to better cooperate with the guide disk 421 when the traction component 42 is working. When the drone needs to be towed, more precise guidance and positioning can be achieved through the contact between the conical surfaces of the two, ensuring the accuracy of the traction direction. By setting the further cooperation between the guide needle 5 and the guide groove 6, during the traction process, the guide needle 5 slides in the guide groove 6, which helps to accurately control the connection between the locking block 425 and the guide disk 421, thereby ensuring the stability of the drone's take-off and landing.

[0047] Among them, a plurality of rotating parts 7 are arranged in a ring shape on the top of the surface of the connecting shaft 422, and the rotating part 7 is rotatably connected to the locking block 425 on one side thereof. By setting the rotating part 7, the locking block 425 can be rotatably connected to the connecting shaft 422. Therefore, the rotation of the connecting shaft 422 can drive a plurality of locking blocks 425 to move closer to or away from the guide disk 421 with the elastic sheet 424 as a fulcrum, thereby realizing or releasing the connection between the locking sheet 426 and the guide disk 421, thereby realizing the take-off and landing release and reception of the drone.

[0048] Among them, the electric winch 8 and the guide frame 17 are bolted on both sides of the platform frame 1, and the surface of the electric winch 8 is wrapped with a steel cable, and one end of the steel cable bypasses the guide frame 17 and is connected to the guide disk 421. By setting the electric winch 8 and the guide frame 17, when the drone needs to be towed, the electric winch 8 is started and the steel cable begins to be retracted and released according to the instructions of the control system. As the electric winch 8 rotates, the steel cable is gradually released or tightened, driving the guide disk 421 to move accordingly, and then the traction force is transmitted to the drone through other components in the traction assembly 42, thereby realizing traction assistance for the drone's take-off and landing process, helping the drone to overcome adverse factors such as wind and take off and land smoothly.

[0049] Among them, both sides of the top of the support platform 3 are bolted with a fixed shell 9, and the inside of the fixed shell 9 is bolted with a hydraulic rod 10, the top of the hydraulic rod 10 is bolted with a connecting block 11, and the connecting block 11 is bolted to the side close to the guide plate 421. By setting structures such as the fixed shell 9, when the guide plate 421 moves, the hydraulic rod 10 will be driven to retract and retract through the connecting block 11, thereby limiting the moving trajectory of the guide plate 421 and allowing it to move smoothly.

[0050] Among them, the front and rear sides of the connecting block 11 are penetrated by a guide rod 12, and the top and bottom of the guide rod 12 are connected to the inner wall of the fixed shell 9, and the surface of the guide rod 12 is sleeved with a tension spring 13, and the side of the tension spring 13 close to the inner wall of the fixed shell 9 is connected to it. By setting the guide rod 12 and the tension spring 13, the guide rod 12 can limit the movement trajectory of the connecting block 11, further improving the stability of the guide plate 421, and the tension spring 13 buffers the movement of the connecting block 11 by releasing or absorbing elastic potential energy, maintaining the stability of the movement of the connecting block 11, thereby ensuring the smooth towing operation of the towing component 42 on the drone.

[0051] The windproof barrier 41 includes two fixed blocks 411, and the fixed block 411 is connected to the platform frame 1 on one side thereof. A rotating shaft 412 is rotatably connected between the two opposite sides of the fixed blocks 411, and a synchronous block 413 is sleeved on the surface of the rotating shaft 412. A windproof plate 414 is bolted to the top of the synchronous block 413, and a plurality of through holes 415 are provided inside the windproof plate 414. A guide vane 416 is rotatably connected inside the through hole 415. The guide vanes 416 on both sides are symmetrically arranged, and the two guide vanes 416 opposite to each other in the middle are symmetrically arranged. By setting the windproof barrier 41, the windproof plate 414 can be connected to the platform frame 1 through the connection between the rotating shaft 412 and the synchronous block 413. , so that the wind shield 414 can adjust the opening and closing angle, so that the wind shield 414 can block the direct impact of strong winds on the take-off and landing area of ​​the drone, and reduce the interference of wind on the drone. At the same time, the through holes 415 opened inside the wind shield 414 and the rotatably connected guide blades 416 can reasonably guide the airflow passing through the wind barrier 41, and the guide blades 416 on both sides and the middle are symmetrically arranged, so that the airflow can be evenly guided and distributed when passing through the wind shield 414, which not only ensures the windproof effect, but also maintains the air circulation in the platform to a certain extent, providing a relatively stable and well-ventilated take-off and landing environment for the drone.

[0052] The working principle of this embodiment is as follows: when encountering strong winds and the UAV needs to take off, the synchronous block 413 is driven to rotate through the rotating shaft 412, so that several windbreaks 414 close the supporting platform 3, creating a relatively stable take-off and landing environment for the UAV. At the same time, through the through hole 415 and the rotatably connected guide blades 416, the airflow passing through the windbreak 41 can be reasonably guided, and then the steel cable is slowly released through the UAV's own ascending power and the electric winch 8, and the traction force is transmitted to the UAV through the traction assembly 42, so that the guide plate 421 can rise slowly. When the flight state is stable, the electric winch 8 is controlled to stop releasing the steel cable, and through the rotation of several rotating parts 7 arranged in a ring shape on the top of the surface of the connecting shaft 422, the locking block 425 is fulcrum with the elastic sheet 424 as the fulcrum. The traction assembly 42 of the stabilizing structure 4 is then waited for the next use instruction. When the UAV is landing, the conical surface setting of the guide disk 421 and the coordinated use of the guide needle 5 and the guide groove 6 make the locking block 425 gradually slide to the center hole position of the guide disk 421. At this time, the movement steps between the connecting shaft 422 and the locking block 425 are reversed to connect the locking plate 426 with the guide disk 421, so that the position of the UAV can be controlled. Finally, the electric winch 8 is used to tighten the steel cable in time, and the downward traction force is transmitted to the UAV through the traction assembly 42, so as to guide the UAV to land accurately on the platform.

[0053] Example 2

[0054] refer to Figure 6-8 A vehicle-mounted UAV take-off and landing platform that can stably operate in a complex environment also includes a support structure 2, wherein the support structure 2 includes a mounting seat 21, and the four corners of the top of the mounting seat 21 are bolted with an adjustment component 22, and the top of the adjustment component 22 is bolted with a movable frame 23, and the movable frame 23 is bolted to the platform frame 1, and a movable rod 24 is suspended at the bottom of the platform frame 1, and a heavy hammer 25 is sleeved on the surface of the movable rod 24, and a push plate 26 is arranged in an annular shape on the surface of the heavy hammer 25, and the push plate 26 is rotatably connected to the side of the adjustment component 22, and an elastic block 27 is bolted between the opposite sides of two adjacent push plates 26. By setting the support structure 2, when the transport vehicle stops on the ground with a certain angle When the weight 25 is tilted, the bottom end of the weight 25 will tilt toward the lower side under the action of gravity, so that the push plate 26 corresponding to the tilt of the weight 25 will move with the tilt of the weight 25, and the push plate 26 will exert a force on the adjustment component 22, so that the adjustment component 22 will move accordingly under the action of this force, so that the adjustment component 22 automatically lifts the inclined part of the platform frame 1, realizes the automatic adjustment of the angle between the take-off and landing platform and the horizontal plane and the balance of the platform. Through the above-mentioned adaptive adjustment process, the entire support structure 2 can maintain the balance of the platform, even when the ground conditions change or the platform is disturbed by external forces, it can ensure that the platform remains stable, thereby ensuring the safety of the take-off and landing of the UAV.

[0055] The adjusting assembly 22 includes a fixed cylinder 221, which is bolted to the top of the mounting seat 21, and the interior of the fixed cylinder 221 is slidably connected with a lifting rod 222, the bottom of the lifting rod 222 is bolted with a connecting rod 223, and the bottom of the connecting rod 223 is bolted to the inner wall of the fixed cylinder 221 and sleeved with a push plate 224, and the surface of the connecting rod 223 is sleeved with a first return spring 225, and the first return spring 225 is connected to the lifting rod 222 and the push plate 224 on one side thereof. The fixed cylinder 221 is connected to a connecting tube 226 at one end, and the other end of the connecting tube 226 is connected to a storage cylinder 227. A pressing plate 228 is slidably arranged inside the storage cylinder 227, and a second return spring 22a is arranged between the pressing plate 228 and the inner wall of the storage cylinder 227. A push rod 229 is bolted to the other side of the pressing plate 228, and the push rod 229 is rotatably connected to the side close to the push plate 26. There is a gap between the pressing plate 228 and the inner wall of the storage cylinder 227 and between the push plate 224 and the inner wall of the fixed cylinder 221. The two push plates 22 and 26 are filled with oil. By setting the adjustment component 22, when the weight 25 applies a force to a certain push plate 26, the push plate 26 will push the corresponding push rod 229 and the pressure plate 228 to move in the storage cylinder 227 and compress the second return spring 22a, thereby squeezing the oil in the storage cylinder 227 and the connecting pipe 226 into the fixed cylinder 221, so that the oil in the fixed cylinder 221 is also further squeezed, so that the push plate 224 pushes the connecting rod 223 and the lifting rod 222 to move upward, and the first return spring 225 is contracted, so that the inclined part of the platform frame 1 can be automatically lifted, and the automatic adjustment of the angle between the lifting and lowering platform and the horizontal plane and the balance of the platform are realized. When the platform frame 1 is in a horizontal position, the weight 25 will release the squeezing of the push plate 26 under the action of gravity. Therefore, the elasticity of the first return spring 225 and the second return spring 22a can return the oil to the storage cylinder 227 and reset the push plate 26, so as to facilitate the next adjustment work.

[0056] Among them, a positioning block 14 is slidably provided at the bottom of the platform frame 1, and the side of the positioning block 14 close to the weight 25 is in contact with it, the top of the positioning block 14 is bolted with a screw block 15, and the internal thread of the screw block 15 passes through a screw rod 16, and the screw rod 16 is rotatably connected to the bottom of the platform frame 1. By setting the positioning block 14, the screw block 15 and the screw rod 16, the position of the weight 25 can be limited when the platform frame 1 does not need to be adjusted, thereby avoiding the synchronous swinging of the weight 25 with the movement of the transport vehicle.

[0057] Working principle of this embodiment: When the vehicle is on the ground with a certain angle, the support structure 2 starts to work, and the bottom end of the weight 25 will tilt to the side with lower terrain under the action of gravity, so that the weight 25 tilts and the corresponding push plate 26 moves with the tilt of the weight 25, and the push plate 26 applies a force to the adjustment component 22, and the push plate 26 pushes the corresponding push rod 229 and the pressure plate 228 to move in the storage cylinder 227, and compresses the second return spring 22a, so that the oil in the storage cylinder 227 and the connecting tube 226 is squeezed into the fixed cylinder 221, so that the oil in the fixed cylinder 221 The oil is also further squeezed, so that the push plate 224 pushes the connecting rod 223 and the lifting rod 222 upward, and the first return spring 225 contracts, so that the inclined part of the platform frame 1 can be automatically lifted, realizing the automatic adjustment of the angle between the lifting and lowering platform and the horizontal plane and the balance of the platform. When the platform frame 1 is in a horizontal position, the weight 25 will release the squeezing of the push plate 26 under the action of gravity. Therefore, through the elasticity of the first return spring 225 and the second return spring 22a, the oil can flow back to the storage tube 227 and the push plate 26 can be reset, so as to facilitate the next adjustment work.
