Description

Technical Field

[0001] This invention relates to the field of vehicle rescue technology, specifically to a pneumatic lifting support device for vehicle rescue. Background Technology

[0002] A pneumatic lifting and support device for vehicle rescue is a specialized rescue equipment that uses compressed air as power to quickly lift and stabilize an accident vehicle. It belongs to the category of emergency rescue and vehicle dismantling rescue equipment. A search reveals Chinese Patent Publication No. CN201850108U, which discloses a pneumatic lifting device. Its features include an upper shell and a lower shell. This utility model has a simple structure, is lightweight, and easy to carry; its design is reasonable and can withstand significant pressure; it is simple to operate and convenient to use, and can be used in soft, uneven, or confined spaces without requiring a dedicated operating space. The existing technical solutions described above have the following drawbacks: existing devices lack an effective anti-rollover structure. During the lifting operation, due to the possibility of the accident vehicle tilting or shifting its center of gravity, the device is prone to tipping over. The existing pneumatic lifting support device is prone to uneven loading and tilting during the lifting process. Once uneven loading and tilting occur, it will not only affect the stability of the lifting, but may also cause the device to overturn, the vehicle to slip, and trigger secondary accidents, threatening the lives of rescue personnel and trapped personnel. It will also damage the accident vehicle and increase rescue losses. In addition, the existing device's support plate structure design is unreasonable. The plate surface is mostly a smooth plane, which has low friction when in contact with the accident vehicle body. During the lifting process, the vehicle body surface may have contaminants such as oil and mud, which further reduces the contact friction between the plate and the vehicle body, making it very easy for the plate to slip relative to the vehicle body, which is not conducive to the smooth progress of rescue operations. Therefore, a pneumatic lifting support device for vehicle rescue is proposed to solve the above-mentioned problems. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a pneumatic lifting support device for vehicle rescue, which has the following advantages:

[0018] 1. This pneumatic lifting support device for vehicle rescue, through the setting of adjustment mechanism and anti-tipping mechanism, uses a servo motor to drive the rotation of elliptical wheels. The eccentric structure of the elliptical wheels pushes the reinforcing frames on both sides, causing the U-shaped plates to slide along the support plate, thereby driving the outer frame to expand outward or contract inward. The telescopic springs between the U-shaped plates provide elastic buffering to ensure that the outer frame maintains symmetry during expansion and avoids tipping due to uneven force on one side. The servo motor drives the bidirectional threaded rod to rotate, and the threaded block moves along the rod axis, driving the strip plate to slide in the rectangular hole of the outer frame through the vertical plate. When the strip plate expands outward, the extension plate contacts the ground, increasing the support area and improving the anti-tipping ability. The anti-wear pad at the bottom of the extension plate reduces friction with the ground and extends service life. The anti-wear pad at the bottom of the outer frame further enhances stability, achieving the purpose of having an anti-tipping structure.

[0019] 2. This pneumatic lifting support device for vehicle rescue features an anti-slip mechanism. The anti-slip plate is connected to the top of the extension cylinder via the top frame, and the clamping frame engages with the clamping plate inside the rectangular box. A fixing spring provides pre-tension to ensure that the anti-slip plate is tightly fitted to the supported object (such as the vehicle chassis). Pulling the pull ring causes the clamping plate to disengage from the clamping frame, allowing for quick replacement or adjustment of the anti-slip plate position to adapt to different shaped supported objects, thus achieving the goal of preventing the top plate from slipping.

The base 3 is fixed to the bottom of the outer cylinder 1 to increase the contact area with the ground and improve overall stability. An anti-slip base plate is set at the bottom to prevent the device from sliding during the rescue process.

[0032] The support assembly 2 includes an extension tube 21. The extension tube 21, which extends to the top of the outer tube 1, is slidably installed on the inner side of the outer tube 1. Two slots 22 are opened on the left and right sides of the inner wall of the outer tube 1. U-shaped rods 23, which pass through the slots 22 on the left and right sides and extend to the outside of the outer tube 1, are fixedly installed on the left and right sides of the extension tube 21.

[0033] The inflation assembly 8 includes an airbag 81. An airbag 81 is placed on the top of the box body 4 and is located inside the outer cylinder 1. The airbag 81 extends to the inside of the extension cylinder 21. An inflation tube 82 extending to the right side of the outer cylinder 1 is fixedly installed on the inside of the airbag 81.

[0034] After the airbag 81 is inflated, it expands and pushes the extension tube 21 upward, providing the main lifting force. It is placed on the top of the box 4 to avoid friction with the inner wall of the outer tube 1. It extends to the inner side of the extension tube 21 to ensure uniform force transmission. The inflation tube 82 is connected to an external air source (such as an air pump) to realize the inflation and deflation of the airbag 81. One end is fixed to the inner side of the airbag 81, and the other end extends to the right side of the outer tube 1 for easy operation.

[0035] The adjustment mechanism 5 includes a support plate 51. Support plates 51 are fixedly installed on both the left and right sides of the inner wall of the box body 4. Two U-shaped plates 52 are slidably installed between the outer sides of the two support plates 51. The two U-shaped plates 52 extend to the front and rear sides of the outer cylinder 1 respectively.

A rotating shaft 56 is fixedly installed at the output shaft of the servo motor 55. An elliptical wheel 57 is fixedly installed at the bottom of the rotating shaft 56. The elliptical wheel 57 is located between the two reinforcing frames 54. Circular grooves 58 are opened on the opposite sides of the two U-shaped plates 52. A telescopic spring 59 is fixedly installed between the inner sides of the circular grooves 58 on the front and rear sides.

[0036] The bottom of the outer frame 53 is provided with an anti-wear pad, the bottom of the base 3 is provided with an anti-slip plate, the inner side of the reinforcing frame 54 is provided with an anti-wear plate, the left and right sides of the U-shaped plate 52 are provided with sliding grooves that are compatible with the support plate 51, the front and rear sides of the inner wall of the box body 4 are provided with perforations that are compatible with the U-shaped plate 52, the inner bottom wall of the extension tube 21 is open, and the inner top wall of the outer tube 1 is open.

[0037] Support plate 51 is fixed to the inner wall of box 4, providing a sliding track for U-shaped plate 52 to ensure its vertical movement stability. It is symmetrically arranged on the left and right sides and cooperates with the sliding groove of U-shaped plate 52 to reduce friction. U-shaped plate 52 connects outer frame 53 and reinforcing frame 54. The front and rear positions of outer frame 53 can be adjusted by sliding to expand or shrink the support range. Circular groove 58 is opened on the inner side, and telescopic spring 59 is installed to provide elastic buffer. Reinforcing frame 54 is fixed to the inner side of U-shaped plate 52 to enhance structural strength and prevent deformation when elliptical wheel 57 is squeezed. Anti-wear plate is set on the inner side to reduce wear with elliptical wheel 57. Servo motor 55 drives elliptical wheel 57 to rotate, and pushes U-shaped plate 52 to slide through eccentric structure to realize automatic adjustment of outer frame 53. Elliptical wheel 57 is located between two reinforcing frames 54 to ensure symmetrical force transmission. Telescopic spring 59 connects U-shaped plate 52 on the front and rear sides to provide reset force, so that outer frame 53 remains stable after adjustment. It is installed in circular groove 58 to avoid interfering with the movement of other components.

[0038] The anti-tipping mechanism 6 includes a strip plate 61. Two strip plates 61 are slidably installed on the inner side of the outer frame 53 and extend to the left and right sides respectively. A connecting ring 62 located on the outer side of the outer frame 53 is fixedly installed on the outer side of the strip plate 61. An extension plate 63 that fits against the bottom of the strip plate 61 is fixedly installed at the bottom of the connecting ring 62.

A servo motor 65 located above the strip plate 61 is fixedly installed on the inner side of the outer frame 53. A bidirectional threaded rod 66 fixedly connected to the inner wall of the outer frame 53 is fixedly installed at the output shaft of the servo motor 65. Two threaded blocks 67 that are slidably connected to the inner wall of the outer frame 53 are threadedly connected to the outer side of the bidirectional threaded rod 66. The bottom of the vertical plate 64 is fixedly connected to the threaded block 67.

[0039] The inner wall of the outer frame 53 has rectangular holes on both the left and right sides that are compatible with the strip 61. The outer side of the bidirectional threaded rod 66 has two threads of equal length and opposite direction. The bottom of the extension plate 63 is provided with an anti-wear pad.

[0040] The outer frame 53 serves as the mounting base for the strip 61. Its position is adjusted by the U-shaped plate 52 to expand the support area. A wear-resistant pad is provided at the bottom to reduce friction with the ground. Rectangular holes are opened on the left and right sides to guide the strip 61 to slide. After the strip 61 slides out of the outer frame 53, the extension plate 63 contacts the ground to form a four-point support to prevent the device from tipping over. A wear-resistant pad is provided at the bottom of the extension plate 63 to adapt to different ground materials. The servo motor 65 drives the bidirectional threaded rod 66 to rotate, which drives the strip 61 to move outward or inward synchronously through the threaded block 67. The bidirectional threaded rod 66 is provided with two reverse threads to ensure symmetrical movement of the strips 61 on both sides. The threaded block 67 moves along the bidirectional threaded rod 66 and connects the strip 61 through the vertical plate 64 to transmit the motion. It slides with the inner wall of the outer frame 53 to ensure stable movement trajectory.

[0041] The anti-slip mechanism 7 includes a positioning plate 701. The positioning plate 701 is fixedly installed on the top of the extension cylinder 21. A top frame 702 extending below the positioning plate 701 is movably installed on the outer side of the positioning plate 701. An anti-slip plate 703 is fixedly installed on the top of the top frame 702. A retaining frame 704 located in front of the positioning plate 701 is fixedly installed on the bottom of the top frame 702. A limiting plate 705 located behind the positioning plate 701 is fixedly installed on the bottom of the top frame 702. A rectangular box 706 located below the retaining frame 704 is fixedly installed on the front side of the extension cylinder 21. A retaining plate 707 extending to the top of the rectangular box 706 and engaging with the retaining frame 704 is slidably installed on the inner side of the rectangular box 706. A rectangular block 708 extending to the front of the rectangular box 706 is fixedly installed on the front side of the retaining plate 707. A pull ring 709 is fixedly installed on the front side of the rectangular block 708. A fixing spring 710 fixedly connected to the inner bottom wall of the rectangular box 706 is fixedly installed on the bottom of the retaining plate 707.

[0042] The top of the anti-slip plate 703 is provided with a strip groove, the bottom of the card frame 704 is provided with a card slot that matches the card plate 707, the inner top wall of the rectangular box 706 is designed with an opening, and the front side of the inner wall of the rectangular box 706 is provided with a limiting strip hole that matches the moving trajectory of the rectangular block 708.

[0043] The positioning plate 701 is fixed to the top of the extension cylinder 21, and the top frame 702 is movably installed on its outside. The anti-slip plate 703 is fixed by a snap-fit ​​structure. The top frame 702 can be quickly disassembled to adapt to the supported objects of different shapes. The top of the anti-slip plate 703 has a strip groove to increase the friction with the supported object (such as the vehicle chassis) and prevent slippage. It is quickly fixed by snapping the frame 704 with the plate 707. The plate 707 is snapped into the slot of the frame 704 under the action of the fixing spring 710 to lock the position of the top frame 702. It can be manually unlocked by the pull ring 709 for easy adjustment or replacement of the anti-slip plate 703. The limiting plate 705 prevents the top frame 702 from moving down too much during installation and ensures that the frame 704 and the plate 707 are aligned.

[0044] When using the device, place it on a hard, flat surface, ensuring the anti-slip base plate of the base 3 is in full contact with the ground to prevent slippage. Connect an external air source (such as an air pump) through the inflation pipe 82, check the airbag 81 for leaks, and slowly inflate the airbag 81. Observe the rising height of the extension cylinder 21, and judge the lifting progress by the position of the U-shaped rod 23 within the slot 22. Once the extension cylinder 21 reaches the target height, close the air source valve and maintain the lifting state using the airbag pressure. Start the servo motor 55 to drive the elliptical wheel 57 to rotate, pushing the U-shaped plate 52 outward to expand the outer frame 53 to the required width. Start the servo motor 65 to drive the bidirectional threaded rod 66 to rotate, causing the strip 61 to... Slide outwards, with extension plate 63 contacting the ground to form four-point support. Place anti-slip plate 703 under the supported object, push top frame 702 to engage clip frame 704 and clip plate 707, and fix spring 710 automatically locks. Gently shake the device to confirm there is no shaking or displacement before proceeding with subsequent rescue operations. Open the air source valve to slowly release the gas in airbag 81. Extension cylinder 21 falls back to its initial position under gravity. Reverse the operation of servo motor 55 and servo motor 65 to retract outer frame 53 and strip plate 61 to their minimum size for easy handling. Clean the surface of the device and check for damage to components such as airbag 81, servo motor 55, and bidirectional threaded rod 66. Replace anti-wear pads and telescopic springs regularly.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0046] In summary, this pneumatic lifting support device for vehicle rescue, through the setting of adjustment mechanism 5 and anti-tipping mechanism 6, uses servo motor 55 to drive elliptical wheel 57 to rotate. The eccentric structure of elliptical wheel 57 pushes the two side reinforcing frames 54, causing U-shaped plate 52 to slide along support plate 51, thereby driving outer frame 53 to expand outward or contract inward. The telescopic spring 59 between U-shaped plates 52 provides elastic buffering to ensure that outer frame 53 maintains symmetry during expansion and avoids tipping due to uneven force on one side. Servo motor 65 drives bidirectional threaded rod 66 to rotate, and threaded block 67 moves along the rod. Axial movement causes the vertical plate 64 to drive the strip 61 to slide within the rectangular hole of the outer frame 53. When the strip 61 expands outward, the extension plate 63 contacts the ground, increasing the support area and improving the anti-tipping ability. The anti-wear pad at the bottom of the extension plate 63 reduces friction with the ground and extends its service life. The anti-wear pad at the bottom of the outer frame 53 further enhances stability, achieving the purpose of having an anti-tipping structure. By setting an anti-slip mechanism 7, the anti-slip plate 703 is connected to the top of the extension cylinder 21 through the top frame 702, and the clamping frame 704 is engaged with the clamping plate 707 inside the rectangular box 706, thus securing the plate. The fixed spring 710 provides preload to ensure that the anti-slip plate 703 is tightly fitted to the supported object (such as a vehicle chassis). Pulling the pull ring 709 disengages the clamping plate 707 from the clamping frame 704, allowing for quick replacement or adjustment of the anti-slip plate 703 to adapt to different shaped supported objects. This achieves the goal of preventing the support plate from slipping, solving the problem of existing devices lacking an effective anti-rollover structure. During lifting operations, accident vehicles may tilt or shift their center of gravity, easily leading to uneven loading and tilting of the device during lifting. Once uneven loading and tilting occur, it will not only affect the lifting process... Instability issues could lead to device overturning, vehicle slippage, and secondary accidents, threatening the lives of rescuers and trapped individuals. It could also damage the vehicle, increasing rescue losses. Furthermore, the existing device's support platform structure is poorly designed, with a smooth surface that results in low friction when in contact with the vehicle. During the lifting process, oil, mud, and other contaminants on the vehicle's surface can further reduce the friction between the platform and the vehicle, making it highly susceptible to slippage. This hinders the smooth progress of rescue operations.
