Description

Technical Field

[0001] This utility model belongs to the field of pneumatic control equipment technology, specifically, it relates to a load-bearing pneumatic ramp. Background Technology

[0002] Traditional lifting devices (such as pneumatic ramps) typically rely on the support structures at the front and rear ends of the panel contacting the base to achieve lifting. However, this design has significant load-bearing capacity limitations: when the panel is raised, it only bears force through the contact points at both ends, resulting in a lack of effective support in the middle area, making it susceptible to deformation or damage due to concentrated load. Especially in heavy-duty scenarios, excessive local stress on the panel can easily reduce the equipment's lifespan and even pose safety hazards.

[0003] Furthermore, existing technologies often suffer from structural redundancy in the reset state (i.e., the lowered state) of lifting mechanisms. For example, the supporting components between the base and the panel may interfere with each other during reset, leading to increased resistance to movement or unreasonable space occupation, thus affecting the compactness and smoothness of the equipment. Utility Model Content

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a load-bearing pneumatic ramp.

[0005] According to the present invention, a load-bearing pneumatic ramp includes a base, a drive component, a connecting plate, rollers, guide strips, and a panel. Two symmetrical drive components are arranged on the top of the base. One end of each drive component is rotatably mounted in the middle of the base, and the other end of each drive component is equipped with a rotatable roller. The rollers are movably mounted in the top elongated hole of the connecting plate via a shaft. The bottom of the connecting plate is rotatably mounted on the rear side of the top surface of the base via a shaft. The connecting plate is movably connected to the drive component via the rollers. An arc-shaped strip is fixedly installed on the rear side of the bottom surface of the panel. The guide strip is fixedly installed on the base. A set of movable pads is installed on the top of the base.

[0006] In a preferred embodiment: the roller slides along the elongated hole of the connecting plate when the drive member extends or retracts.

[0007] In a preferred embodiment: the roller is configured to correspond to the bottom contour of the arc-shaped strip.

[0008] In a preferred embodiment: grooves are provided on the front sides of both the left and right walls of the base, and positioning wheels corresponding to the grooves are fixedly installed on both the left and right ends of the panel.

[0009] In a preferred embodiment: the guide bar is provided correspondingly to the roller.

[0010] In a preferred embodiment: a spring is installed on the rear side of the top surface of the base, and the spring is a compression spring.

[0011] In a preferred embodiment: a sliding pad is fixedly installed on the side of the base and below the connecting plate of the movable pad assembly.

[0012] In a preferred embodiment: a fixing pad is fixedly installed between the two connecting plates.

[0013] In a preferred embodiment: a plurality of pads corresponding to the movable pad group are fixedly installed at the bottom of the panel.

[0014] In a preferred embodiment: the two rollers are connected to the beginning of a connecting rod on the side near the movable pad assembly, and the end of the connecting rod is movably connected to the movable pad assembly.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When this utility model is used, the panel angle is adjusted to solve the problem that the height difference between the indoor and outdoor areas when the door is opened is not conducive to the entry and exit of personnel, testing instruments and objects being tested. At the same time, it ensures the compactness of the reset state and takes into account the reliability of the lifting action and the space utilization rate.

[0017] When this utility model is used, multiple sets of movable pads are added between the panel and the base. When the panel is raised, the pads fixed on the panel and the movable pads in the base overlap vertically to form multi-point distributed support, effectively dispersing the load and enhancing the compressive strength. When the panel is lowered, the two automatically separate and avoid structural interference. It is suitable for industrial equipment or logistics loading and unloading scenarios with high load-bearing capacity requirements. Attached Figure Description

[0027] Detailed Implementation

[0028] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.

[0029] like Figures 1-6 As shown, this utility model discloses a load-bearing pneumatic ramp, including a base 1, a driving component 2, a connecting plate 3, rollers 4, guide strips 8, and a panel 11. Two symmetrically positioned driving components 2 are arranged above the base 1. One end of each driving component 2 is rotatably mounted in the middle of the base 1, while the other end of each driving component 2 is equipped with a rotatable roller 4. The roller 4 is movably mounted in a long, narrow hole at the top of the connecting plate 3 via a shaft. The bottom of the connecting plate 3 is rotatably mounted on the rear side of the top surface of the base 1 via a shaft. The connecting plate 3 is movably connected to the driving components 2 via the rollers 4. An arc-shaped strip 13 is fixedly mounted on the rear side of the bottom surface of the panel 11. The rollers 4 are correspondingly positioned to the bottom contour of the arc-shaped strip 13. The left and right walls of the base 1... The front side is provided with grooves. Positioning wheels 14 corresponding to the grooves are fixedly installed at both ends of the panel 11. Guide bars 8 are fixedly installed on the base 1, and guide bars 8 are set in correspondence with rollers 4. Guide bars 8 are used to limit the position of connecting plate 3 when the drive component 2 retracts into place, so as to ensure that the connecting plate 3 and the drive component 2 maintain a specific angle so that the connecting plate 3 can be smoothly flipped upward when the drive component 2 extends again. A spring 9 is installed on the rear side of the top surface of the base 1. The spring 9 provides buffer and deceleration for the panel 11 to descend. Slip pads 10 are fixedly installed on the side of the base 1 and below the connecting plate 3 of the movable pad group 7. Slip pads 10 can reduce the friction when the drive component 2, connecting plate 3 and movable pad group 7 move.

[0030] A fixed pad 5 is fixedly installed between the two connecting plates 3. A movable pad group 7 is installed on the top of the base 1. Multiple pads 12 corresponding to the movable pad group 7 are fixedly installed on the bottom of the panel 11. The two rollers 4 are connected to the ends of the connecting rods 6 by a shaft on the side near the movable pad group 7. The ends of the connecting rods 6 are movably connected to the movable pad group 7. When the driving component 2 retracts, it drives the connecting plate 3 and the fixed pad 5 to flip downwards. At the same time, it drives the movable pad group 7 to move through the connecting rod 6. When the driving component 2 retracts to its position, the movable pad group 7 and the pads 12 on the panel 11 are staggered and do not affect each other. When the driving component 2 extends, it drives the connecting plate 3 and the fixed pad 5 to flip upwards. The rollers 4 contact the arc strip 13 to drive the panel 11 to rise and drive the movable pad group 7 to move. When the driving component 2 extends to its position, the fixed pad 5 and the movable pad group 7 in the base 1 vertically overlap with the pads 12 on the panel 11.

[0031] Working principle

[0032] In use, the retraction action is initiated by the drive component 2, and the connecting plate 3 is flipped downward by the roller 4. The roller 4 slides along the bottom contour of the arc strip 13, changing the contact position to adjust the downward angle of the panel 11. At the same time, the positioning wheel 14 at the end of the panel 11 rolls in the groove of the base 1, limiting the horizontal displacement of the panel 11. The panel 11 contacts the spring 9 on the base 1, and the compression of the spring 9 achieves deceleration and buffering. When the connecting plate 3 flips downward, the connecting rod 6 drives the movable pad strip group 7 to move laterally, so that it is completely misaligned with the pad strip 12. When the drive component 2 retracts into place, the roller 4 falls on the guide strip 8, maintaining the upward tilt angle between the connecting plate 3 and the drive component 2, reserving space for the next extension action.

[0033] When the extension action needs to be initiated by the drive component 2, the connecting plate 3 is pulled upward by the roller 4 and rotated upward. The roller 4 slides along the bottom contour of the arc strip 13, causing the panel 11 to rise at a set angle. When the connecting plate 3 rotates upward, the movable pad group 7 is moved by the connecting rod 6 so that it overlaps vertically with the pad 12, thereby enhancing the load-bearing capacity of the panel 11. After the drive component 2 extends into place, the fixed pad 5, the movable pad group 7 and the pad 12 form a vertical support structure to ensure that the panel 11 can stably bear the load.
