Description

Technical Field

[0001] This invention relates to the technical field of temporary devices for people or vehicles to enter from one floor to another, and specifically to an adjustable slope warehouse ramp auxiliary device. Background Technology

[0002] Warehouse ramps serve as crucial transitional facilities for heavy-duty vehicles entering and exiting warehouses. However, in practice, they often suffer from fixed elevation differences and non-adjustable ramp slopes. In some scenarios, transitional structures with switchable passage modes are required at the ramp location to balance temporary vehicle passage with warehouse safety management. While some existing ramp auxiliary devices offer height adjustment, most only provide simple elevation or slope adjustment, lacking temporary support functions for heavy-duty passage and status locking. This makes it difficult to meet the need to promptly block the passage path after heavy-duty vehicles have passed quickly, preventing unauthorized vehicles from parking in front of the warehouse door.

[0003] Meanwhile, existing temporary support devices generally suffer from insufficient support capacity and weak structural rigidity. When subjected to the pressure of heavy vehicles exceeding 20 tons or prolonged parking, they are prone to deformation, platform settlement, and loss of leveling accuracy. This makes it impossible to ensure the smooth passage of heavy vehicles or to maintain a stable blocking state after passage. Although some devices have a certain degree of adjustment capability, the adjustment mechanism is integrated with the load-bearing structure. Heavy impacts can easily damage the adjustment components, making it impossible to simultaneously fulfill the dual functions of temporary leveling support under heavy loads and blocking the vehicle's position after passage. This affects the safety of heavy-load passage and fails to meet the warehouse's requirements for controlling vehicle entry and exit paths, resulting in significant limitations and safety hazards. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to propose an adjustable slope warehouse ramp auxiliary device to solve the problems mentioned in the background section above.

[0005] This invention is achieved through the following technical solution: An adjustable-slope warehouse ramp auxiliary device includes: A first platform, a recess, and a second platform are arranged sequentially along the X-axis, and the first platform and the second platform have different heights; The lifting actuator has two sets of lifting ends arranged along the X-axis at the lower end of the bearing platform, so that the bearing platform can be adjusted and set in the recess. The bearing platform can be adjusted to at least one state: the two ends of the bearing platform along the X-axis are respectively connected to the first platform and the second platform; An auxiliary support unit is provided for each of the lifting actuators; the auxiliary support unit includes a movable component, a longitudinal guide mechanism, a guide component, and a transverse actuator. The movable component is vertically and flexibly positioned in the recess via several longitudinal guide mechanisms. A swing support is rotatably provided on the top of the movable component, which is used to support the bottom of the bearing platform. The guide member is movably disposed in the recess along the X-axis direction and is equipped with a transverse movement actuator for moving the guide member; the guide member is provided with a guide groove, which includes a lower flat support groove, an inclined support groove and an upper flat support groove connected in sequence; the movable member is fixedly provided with a guide rod, and the guide rod is slidably disposed in the guide groove.

[0006] Furthermore, the supporting platform can also exist in a second state through adjustment: the first platform and / or the second platform form a stepped fault with the supporting platform.

[0007] Furthermore, the inclination angle of the inclined support groove is 25.5°±5° with respect to the horizontal plane.

[0008] Furthermore, one side of the bearing platform is provided with a clearance groove along the length direction, and one of the lifting actuators passes through the clearance groove via a connecting rod, thereby connecting the bearing platform and the lifting actuator.

[0009] Furthermore, the longitudinal guiding mechanism includes a guide sleeve and a guide rod. The guide sleeve is fixedly disposed in the recess in the vertical direction, and the guide rod is fixedly connected to the movable part in the vertical direction.

[0010] Furthermore, the guide member includes a lower base plate and two outer side plates that are perpendicularly connected to the lower base plate and spaced apart, and the two outer side plates are provided with guide grooves; the movable member includes an upper base plate and two inner side plates that are perpendicularly connected to the upper base plate and spaced apart, and the two guide rods are respectively perpendicularly connected to the inner side plates.

[0011] Furthermore, the supporting platform includes an anti-slip plate and a profiled steel beam welded and fixed below the anti-slip plate.

[0012] Furthermore, both the lifting actuator and the traversing actuator are hydraulic cylinders.

[0013] Furthermore, at least two of the aforementioned lifting actuators and two of the aforementioned auxiliary support units are sequentially arranged along the Y-axis direction.

[0014] The beneficial effects of the present invention are as follows: By setting auxiliary support units at the lower end of the bearing platform and corresponding to each set of lifting actuators, the auxiliary support units can provide rigid support to the bearing platform after it is lifted into position, so that the lifting actuators can unload all or most of the force, avoid long-term pressure damage, extend service life, and stably meet the needs of heavy-duty vehicles with a load capacity of more than 20 tons for passage and long-term static parking.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] Reference Figures 1 to 5 As shown, an adjustable-slope warehouse ramp auxiliary device includes: A first platform A, a recess B, and a second platform C are arranged sequentially along the X-axis, and the first platform A and the second platform C have different heights; The lifting actuator 2, with the lifting ends of the two sets of lifting actuator 2 arranged along the X-axis direction at the lower end of the bearing platform 1, allows the bearing platform 1 to be adjustablely positioned in the recess B. The bearing platform 1 can be adjusted to at least have one state: the two ends of the bearing platform 1 along the X-axis direction are respectively connected to the first platform A and the second platform C. Auxiliary support unit 3 is provided for each of the lifting actuators 2; the auxiliary support unit 3 includes a movable part 31, a longitudinal guide mechanism 32, a guide part 33, and a transverse actuator 34; The movable part 31 is vertically and flexibly disposed in the recess B through a plurality of the longitudinal guide mechanisms 32. The top of the movable part 31 is rotatably provided with a swing support 35, which is used to support the bottom of the bearing platform 1. The guide member 33 is movably disposed in the recess B along the X-axis direction and is equipped with a transverse movement actuator 34 for moving the guide member 33; the guide member 33 is provided with a guide groove 331, which includes a lower flat support groove 3311, a diagonal support groove 3312 and an upper flat support groove 3313 connected in sequence; the movable member 31 is fixedly provided with a guide rod 313, and the guide rod 313 is slidably disposed in the guide groove 331.

[0023] The present invention provides an auxiliary support unit 3 at the lower end of the carrying platform 1, corresponding to each set of lifting actuators 2. The auxiliary support unit 3 can provide rigid support to the carrying platform 1 after it is lifted into position, so that the lifting actuators 2 can unload all or most of the force, avoid long-term pressure damage, and extend service life.

[0024] Specifically, the external heavy load borne by the lifting platform 1 is transmitted to the moving part 31 and the guide rod 313 via the swing support 35, and then to the guide groove 331 of the guide member 33 via the guide rod 313. The load is then transmitted to the support platform 36 below via the guide member 33, and finally to the ground foundation via the support platform 36. In this way, all or most of the working load of the lifting actuator 2 is distributed through the auxiliary support unit 3, fundamentally solving the problems of poor reliability and insufficient stability caused by the long-term static pressure support of hydraulic cylinders and air cylinders in traditional lifting platforms.

[0025] The supporting platform 1 can also exist in a second state through adjustment: the first platform A and / or the second platform C form a stepped fault with the supporting platform 1. This stepped fault can form a physical barrier structure in front of the warehouse door, preventing unauthorized vehicles from parking in the passage in front of the warehouse door, effectively preventing unauthorized vehicles, non-motorized vehicles, and pedestrians from arbitrarily occupying the passage in front of the warehouse door.

[0026] When a vehicle that has been identified and certified as meeting the passage requirements needs to pass, the lifting actuator 2 drives the adjustment so that the two ends of the bearing platform 1 along the X-axis direction are smoothly connected to the first platform A and the second platform C respectively, forming a continuous and smooth passage surface for forklifts, trucks and other operating equipment to pass safely and smoothly. Identification and certification can be done manually or through existing means such as facial recognition.

[0027] In this invention, the carrier platform 1 can be switched in the following positions: When the supporting platform 1 is raised to its highest point and parallel to the horizontal plane, the lifting actuator 2 first raises the supporting platform 1 to its highest position. Then, the lateral movement actuator 34 drives the guide member 33 to move, causing the guide rod 313 on the movable member 31 to move along the guide groove 331 to the upper flat support groove 3313. At this time, the swing support member 35 abuts against the lower end of the supporting platform 1, forming a stable auxiliary support. In this supported state, the external load borne by the supporting platform 1 is sequentially transmitted to the guide rod 313 of the movable member 31, and directly transmitted to the support platform 36 through the upper flat support groove 3313 of the guide groove 331, realizing the rigid support and distribution of the load. At this time, the lifting actuator 2 no longer bears the longitudinal load, which can effectively avoid deformation or damage caused by long-term pressure. At the same time, the guide rod 313 presses down longitudinally into the guide groove 331, and under the action of the downward pressure, a reliable mechanical self-locking can be achieved, further improving the support stability and safety of the device under heavy load conditions.

[0028] Similarly, when the supporting platform 1 is lowered to its lowest point and parallel to the horizontal plane, the lifting actuator 2 first lowers the supporting platform 1 to its lowest position; then, the lateral movement actuator 34 drives the guide member 33 to move, causing the guide rod 313 on the movable member 31 to move along the guide groove 331 to the lower flat support groove 3311. At this time, the swing support member 35 abuts against the lower end of the supporting platform 1, forming a stable auxiliary support. In this supported state, the external load borne by the supporting platform 1 is sequentially transmitted to the guide rod 313 of the movable member 31, and directly transmitted to the support platform 36 through the lower flat support groove 3311 of the guide groove 331, realizing rigid support and distribution of the load; at this time, the lifting actuator 2 no longer bears the longitudinal load, which can effectively avoid deformation or damage caused by long-term pressure. At the same time, the guide rod 313 presses down longitudinally into the guide groove 331, and under the action of the downward pressure, a reliable mechanical self-locking can be achieved, further improving the support stability and safety of the device under heavy load conditions.

[0029] When it is necessary to tilt the load-bearing platform 1, refer to Figure 5As shown, the two sets of lifting actuators 1 can be controlled independently. Each set consists of at least two synchronously controlled lifting actuators 1. One set of lifting actuators 2 drives the bearing platform 1 to the required tilt angle. Then, the guide member 33 is moved by the corresponding lateral movement actuator 34, causing the guide rod 313 on the movable member 31 to move along the guide groove 331 to the inclined support groove 3312. At this time, the swing support member 35 adaptively rotates to abut against the lower end of the bearing platform 1, forming a stable auxiliary support. In this tilted support state, the external load borne by the bearing platform 1 is sequentially transmitted to the guide rod 313 of the movable member 31. Most of the force in the Y-axis direction is directly transmitted to the support platform 36 through the inclined support groove 3312 of the guide groove 331, achieving rigid support and force distribution of the load. The load transmitted to the lateral movement actuator 34 retains only the force in the X-axis direction, greatly reducing the load borne by the lateral movement actuator 34 and also greatly reducing the longitudinal load borne by the lifting actuator 2.

[0030] This invention achieves the adjustment of the bearing platform 1 and its fixed support after adjustment, requiring the coordinated operation of various actuators. This invention uses two sets of lifting actuators 2 spaced apart along the length of the lower end of the bearing platform 1. The two sets of lifting actuators 2 can be adjusted and operated independently, and can adaptively adjust the tilt angle of the bearing platform 1 according to the working conditions such as the ground slope and docking height, so as to meet the tilting docking requirements of different sites. At the same time, auxiliary support units 3 are set corresponding to each set of lifting actuators 2, which can provide rigid support to the bearing platform 1 after it is lifted and tilted into place, so that the lifting actuators 2 are unloaded from the force, avoiding long-term pressure damage and extending service life.

[0031] It should be noted that in this invention, when the carrying platform 1 is raised to the highest point, lowered to the lowest point, or in an inclined state, it can be switched to the above-mentioned state two according to the actual ground conditions and usage requirements, thereby forming a corresponding stepped fault in front of the warehouse door; or the carrying platform 1 can be switched to the above-mentioned state one, so that the two ends of the carrying platform 1 along the X-axis direction are respectively connected to the first platform A and the second platform C, allowing the transport vehicles or operating equipment to pass normally.

[0032] Specifically, the auxiliary support unit 3 also includes a support platform 36, which is fixed in the recess B. The upper end of the support platform 36 is provided with at least two slide rails 37 arranged at intervals along the Y-axis direction. The upper end of each slide rail 37 is provided with at least two sliders 38 arranged at intervals along the X-axis direction. The lower end of the guide member 33 is fixed to the sliders 38, thereby realizing the smooth sliding of the guide member 33 along the length direction of the support platform 36.

[0033] The swing support 35 is rotatably connected to the movable part 31 via the rotating shaft 39, so that the upper end surface of the swing support 35 adaptively fits the lower end surface of the bearing platform 1, thereby increasing the contact area between the swing support 35 and the bearing platform 1, reducing local pressure, and improving service life.

[0034] Furthermore, the inclination angle of the inclined support groove 3312 is 25.5° ± 5° with the horizontal plane. Figure 5 As shown in the mid-angle R), the force direction of the guide rod 313 in the inclined brace groove 3312 is highly matched with the load transmission direction of the bearing platform 1 under the tilting condition, so as to achieve the optimal force transmission angle and force decomposition effect while ensuring sufficient support stiffness.

[0035] Furthermore, one side of the bearing platform 1 is provided with a clearance groove 11 along the length direction, and one of the lifting actuators 2 passes through the clearance groove 11 via a connecting rod, thereby connecting the bearing platform 1 and the lifting actuator 2.

[0036] In the above scheme, by setting a clearance groove 11 extending along the length direction on one side of the bearing platform 1, and passing a lifting actuator 2 through the clearance groove 11 via a connecting rod to achieve a hinged connection with the bearing platform 1, the connecting rod can generate adaptive displacement and rotation in the clearance groove 11 when the bearing platform 1 is tilted, providing effective clearance space for the tilting and swinging of the bearing platform 1, and avoiding motion interference or jamming between the lifting actuator 2 and the bearing platform 1.

[0037] The longitudinal guiding mechanism 32 includes a guide sleeve 321 and a guide rod 322. The guide sleeve 321 is fixedly disposed in the recess B in the vertical direction, and the guide rod 322 is fixedly connected to the movable part 31 in the vertical direction.

[0038] In the above scheme, by setting a guide sleeve 321 fixed to the support platform 36 in the auxiliary support unit 3, and a guide rod 322 connected to the movable part 31 and passing through the guide sleeve 321, and the guide sleeve 321 is arranged in the vertical direction, it can play a precise guiding and limiting role for the lifting and lowering movement of the movable part 31, effectively constrain the movement trajectory of the movable part 31, and avoid the movable part 31 from deviating, shaking or tilting during the process of moving with the guide part 33 and driving the swing support 35 to move, ensuring that the movable part 31 always rises and falls smoothly in the preset direction.

[0039] Furthermore, the guide member 33 includes a lower base plate 332 and two outer side plates 333 that are perpendicularly connected to the lower base plate 332 and spaced apart, and the two outer side plates 333 are provided with guide grooves 331; the movable member 31 includes an upper base plate 311 and two inner side plates 312 that are perpendicularly connected to the upper base plate 311 and spaced apart, and the two guide rods 313 are respectively perpendicularly connected to the inner side plates 312 and embedded in the guide grooves 331.

[0040] In the above scheme, by adopting a double-layered arrangement structure with a lower base plate 332 and symmetrical outer side plates 333, and an upper base plate 311 and symmetrical inner side plates 312 respectively, the guide component 33 and the movable component 31 form an inner and outer nested fit, which greatly saves installation space, makes the structure more compact, and is suitable for the narrow installation environment of underground lifting devices. At the same time, the guide groove 331 and the guide rod 313 are both symmetrically arranged, so that the movable component 31 is subjected to uniform force and moves smoothly during lifting and swinging, effectively avoiding uneven loading, jamming and lateral swaying, significantly improving the structural stability and support reliability of the auxiliary support unit 3, and extending the service life of the device.

[0041] Furthermore, by fixing the guide rod 322 to the lower end face of the upper base plate 311, the guide support point and the load-bearing point are closer, the force transmission path is shorter, and the rigidity is stronger. With the symmetrically arranged guide grooves 331 and guide rods 313, the moving part 31 is subjected to uniform force and moves smoothly during lifting and swinging. This can effectively avoid uneven loading, jamming, and lateral swaying, further improving the structural stability and support reliability of the auxiliary support unit 3 and extending the overall service life of the device.

[0042] Furthermore, the transverse actuator 34 is a double-headed telescopic hydraulic cylinder, and the two drive ends of the double-headed telescopic hydraulic cylinder are respectively connected to the guide members 33 of the two auxiliary support units 3.

[0043] The transverse actuator 34 is assembled by using two single-head telescopic hydraulic cylinders and welding the tail of the cylinder body to form a double-head telescopic hydraulic cylinder. This greatly saves lateral installation space. Furthermore, through the above connection method, when one telescopic end is offset, the other telescopic end is also offset, which can ensure that the output ends of the double-head telescopic hydraulic cylinder are arranged coaxially.

[0044] The two output ends of the dual-head telescopic hydraulic cylinder can be controlled and driven independently, and can respectively drive the guide 33, movable part 31 and swing support 35 on the corresponding side to move, realize the differentiated support posture of the auxiliary support on both sides, and make the bearing platform 1 flexibly tilt to either side according to the usage requirements, with higher degree of freedom of tilt adjustment and stronger adaptability to working conditions.

[0045] Furthermore, the supporting platform 1 includes an anti-slip plate 12 and a profile steel beam 13 welded and fixed below the anti-slip plate 12.

[0046] In the above scheme, the anti-slip plate 12 is supported by a frame structure formed by welded steel beams 13. This structure boasts high strength and load-bearing capacity, effectively resisting bending deformation caused by heavy-load rolling, ensuring the overall rigidity and flatness of the load-bearing platform 1, and preventing deformation and collapse over long-term use. The steel beams 13 and the anti-slip plate 12 are welded together, ensuring a firm and reliable connection and uniform overall stress distribution, meeting the requirements for long-term stable use under heavy-load truck rolling conditions. The upper surface of the anti-slip plate 12 is equipped with anti-slip textures, anti-slip bumps, anti-slip mesh, or anti-slip toothed grooves, increasing the surface friction coefficient and effectively preventing vehicles or handling equipment from slipping when lifting or moving on the platform, thus improving operational safety.

[0047] At least two sets of parallel auxiliary support units 3 are arranged along the width direction of the bearing platform 1 to ensure that the lifting device is subjected to balanced force and operates smoothly in the width direction, avoiding lateral tilting or swaying. Two sets of auxiliary support units 3 are arranged along the length direction of the bearing platform 1 so that the lifting device can be independently adjusted at both ends in the length direction to achieve forward and backward tilting, meeting the tilting operation requirements under different working conditions.

[0048] The adjustable-slope warehouse ramp auxiliary device described in this invention is also equipped with a multi-unit linkage remote operation function, enabling centralized control and remote start / stop of multiple devices, thus preventing unauthorized personnel from misoperating on-site. The specific solution is as follows: The warehouse protective door must be opened first. After the positioning sensor installed at the warehouse protective door detects that the door is fully open and sends a positioning signal, the intelligent control system unlocks the operating authority of the lifting device of this invention. Before operation, the intelligent control system must complete the operator's identity authentication through at least one of facial recognition, fingerprint recognition, or password verification. Only after successful authentication can the lifting device's lifting, tilting, and other actions be initiated.

[0049] The intelligent control system is equipped with a visual display screen 5, which collects and displays the detection data of each sensor and electronic ruler in real time, including the real-time position, tilt angle, power supply mode and warehouse door position status of the carrying platform 1, etc., providing intuitive feedback on the operating status of the device, making it easy for operators to judge the working status of the carrying platform 1, such as lifting position, lowest resistance, tilting operation, etc.

[0050] In addition, the power supply system for opening and closing the gate 4 uses 380V mains power as the conventional power supply method. In the event of a sudden power outage or grid failure, it can automatically switch to emergency DC battery 6 for driving, or manually operate the hydraulic manual pump 77 to realize the lifting and resetting operation of the lifting device, ensuring that the device can still complete the passage control or emergency response normally under extreme working conditions.
