Description

Technical Field

[0001] This utility model relates to the field of rescue engineering technology, specifically to an emergency rescue rapid loading and unloading device. Background Technology

[0002] Emergency rescue vehicles are specialized vehicles designed for disaster relief and rescue missions. They are typically modified from a car chassis and equipped with a wide range of rescue equipment, such as winches, truck-mounted cranes, and overhead lighting systems. Depending on their purpose, they can be categorized into general disaster relief vehicles, chemical rescue fire trucks, earthquake rescue vehicles, etc. Emergency rescue vehicles possess strong mobility, can adapt to various complex road conditions, and can quickly reach the rescue site. They also have multiple functions including lifting, towing, demolition, and lighting, providing powerful support for rescue operations in various emergencies such as fires, earthquakes, and traffic accidents. They are an indispensable and crucial piece of equipment in emergency rescue systems.

[0003] It achieves flexible mobility by relying on a modified car chassis, and provides energy support for on-board equipment through a power transmission system. For example, the engine drives a hydraulic pump to power lifting and demolition devices, or drives a generator to power lighting and communication equipment.

[0004] In the field of emergency rescue, rescue vehicles need to be equipped with various heavy or large rescue equipment (such as demolition tools, hydraulic pumps, etc.). However, due to the narrow space of the vehicle's upper structure and the high ground clearance of the chassis, the existing loading and unloading methods have the following problems: manual loading and unloading is labor-intensive and time-consuming, making it difficult to meet the "rapid response" requirements of emergency rescue; traditional hoisting equipment has a complex structure, occupies a large space, and has poor compatibility with rescue vehicles; during the loading and unloading process, the equipment is prone to collisions due to inconvenient posture adjustment, which affects the service life of the equipment.

[0005] Therefore, this utility model proposes a compact and flexible emergency rescue rapid loading and unloading device, which achieves efficient loading and unloading of rescue equipment by optimizing the linkage mechanism and driving method. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing emergency rescue equipment, such as slow loading and unloading speed and limitations imposed by space and chassis height, and to provide an emergency rescue rapid loading and unloading device that can quickly complete equipment loading and unloading and has strong adaptability.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An emergency rescue rapid loading and unloading device includes two bases fixed to the floor of a rescue vehicle. The inner walls of the two bases are rotatably connected to a swing arm linkage mechanism. The swing arm linkage mechanism is rotatably connected to a rescue device bracket. A hydraulic cylinder is rotatably connected to the swing arm linkage mechanism.

[0009] Furthermore, the base is designed in an L-shape, with pin holes at both ends and a height difference between the two pin holes.

[0010] Furthermore, the swing arm linkage mechanism includes a first link and a second link hinged to a pin hole in the base via a pin shaft. The other end of the second link is hinged to the upper end of the inner side of the rescue device bracket. The other end of the first link is connected to a shaft. A third link is rotatably connected to the shaft. The other end of the third link is hinged to the upper middle part of the inner side of the rescue device bracket.

[0011] Furthermore, a horizontal adjusting rod is rotatably connected to the middle of the shaft, and the other end of the horizontal adjusting rod is hinged to the upper part of the outside of the rescue device bracket.

[0012] Furthermore, the cylinder barrel of the hydraulic cylinder is hinged to the lower end face of connecting rod one, and the piston rod of the hydraulic cylinder is hinged to the upper end face of connecting rod three.

[0013] Furthermore, the rescue device support is equipped with a storage shelf.

[0014] Furthermore, the connecting rod three is provided in two parts, which are located at both ends of the shaft.

[0015] Furthermore, the connecting rod three includes a threaded tube, with screws connected to both ends of the threaded tube, and the screws are respectively hinged to the shaft and the rescue device bracket.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model uses a hydraulic cylinder to drive a swing arm linkage mechanism to rotate around a base. A horizontal adjustment rod adjusts the horizontal position of the rescue device bracket, and the other end of the swing arm linkage mechanism drives the rescue device bracket to move, enabling rapid loading and unloading of the rescue device. This significantly shortens the loading and unloading time of rescue equipment and supplies, gaining valuable momentum for rescue operations in emergency situations and preventing the disaster from escalating or the best rescue opportunity from being missed due to slow loading and unloading. Its ease of operation reduces over-reliance on the professional skills of rescue personnel. Even in complex and chaotic on-site environments, loading and unloading operations can be completed quickly, reducing delays caused by human error. At the same time, the device has a stable fixing and protection function, ensuring the safety of equipment, supplies, or personnel during transportation and preventing damage caused by bumps and collisions.

[0018] 2. This utility model enables rapid loading and unloading: by driving the swing arm linkage mechanism with a hydraulic cylinder, the automatic lifting and attitude adjustment of the rescue device bracket is realized, which greatly shortens the loading and unloading time and meets the timeliness requirements of emergency rescue;

[0019] 3. This utility model has strong adaptability: the height difference pin hole design of the L-shaped base, combined with the multi-link mechanism, can adapt to the characteristics of the high ground clearance of the rescue vehicle chassis, while reducing the space occupied by the vehicle's upper structure;

[0020] 4. The double-linkage and three-bar horizontal adjustment rods of this utility model enhance the rigidity and stability of the mechanism, preventing shaking or jamming during equipment loading and unloading.

[0021] 5. The storage rack on the support frame of this utility model rescue device can directly place small rescue equipment, further improving loading and unloading efficiency and equipment portability. Attached Figure Description

[0028] 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.

[0029] Reference Figures 1 to 4This utility model provides an embodiment of an emergency rescue rapid loading and unloading device, comprising two bases 1 fixed to the floor of a rescue vehicle. These two bases 1 serve as basic support components, providing rotation mounting points for the swing arm linkage mechanism 2, ensuring the structural stability of the entire device, and forming the foundation for the coordinated operation of all components. The inner walls of both bases 1 are rotatably connected to the swing arm linkage mechanism 2. Through this rotatable connection, the swing arm linkage mechanism 2 can rotate flexibly around the base 1, providing rotational freedom for adjusting the position of the rescue device and enabling operation at different angles. The swing arm linkage mechanism 2 is rotatably connected to a rescue device bracket 3, and a hydraulic cylinder 4 is rotatably connected to it. The hydraulic circuit of the hydraulic cylinder 4 is connected to the hydraulic circuit of the rescue vehicle. The extension and retraction of the hydraulic cylinder 4 provides driving force for the rotation of the swing arm linkage mechanism 2, realizing the lifting and retraction of the swing arm.

[0030] The base 1 is designed in an L-shape, with pin holes 5 at both ends, and a height difference between the two pin holes 5. The swing arm linkage mechanism 2 includes a first connecting rod 6 and a second connecting rod 7 hinged to the pin holes 5 of the base 1 via pins. The other end of the second connecting rod 7 is hinged to the upper inner side of the rescue device bracket 3. The other ends of the first connecting rod 6 are connected to a shaft 8, and a third connecting rod 9 is rotatably connected to the shaft 8. The other end of the third connecting rod 9 is hinged to the upper middle part of the inner side of the rescue device bracket 3. As the core transmission component of the mechanism, the connecting rod transmits the power of the hydraulic cylinder 4 to the entire mechanism, driving the mechanism to complete various actions while ensuring the coordination of the mechanism's movement. A horizontal adjusting rod 10 is rotatably connected to the middle of the shaft 8, and the other end of the horizontal adjusting rod 10 is hinged to the upper outer side of the rescue device bracket 3. The horizontal adjusting rod 10 can rotate adaptively with the movement of the swing arm linkage mechanism 2, and can accurately adjust the horizontal position of the rescue device bracket 3 to ensure a stable horizontal state during operation.

[0031] The cylinder barrel of the hydraulic cylinder 4 is hinged to the lower end face of the connecting rod 6, and the piston rod of the hydraulic cylinder 4 is hinged to the upper end face of the connecting rod 9; this allows the hydraulic cylinder 4 to transmit power flexibly, avoids motion interference, and ensures efficient power transmission. The rescue device bracket 3 is equipped with a storage rack 11; the storage rack 11 can directly place small rescue equipment, further improving loading and unloading efficiency and equipment portability.

[0032] Furthermore, there are two connecting rods 9, which are set at both ends of the shaft 8. The connecting rod 9 includes a threaded tube 12, and the two ends of the threaded tube 12 are connected to screws 13. The screws 13 are respectively hinged to the shaft 8 and the rescue device bracket 3. The length of the connecting rod 9 can be adjusted by rotating the threaded tube 12.

[0033] The working principle of this utility model is as follows: This emergency rescue rapid loading and unloading device uses two bases 1 fixed to the floor of the rescue vehicle as a fixed foundation. During operation, the hydraulic cylinder 4 serves as a power source. Its drive end outputs thrust or pull force through a rotational connection with the swing arm linkage mechanism 2, causing the connecting rod of the swing arm linkage mechanism 2 to rotate around the inner wall of the base 1, thus expanding or contracting the entire mechanism. During the movement of the swing arm linkage mechanism 2, the horizontal adjustment rod 10 on the adjacent side rotates synchronously, adjusting its own angle to correct the horizontal posture of the rescue device bracket 3 in real time, preventing the bracket from tilting due to the mechanism's movement. At the same time, the other end of the swing arm linkage mechanism 2 is rotatably connected to the outer wall of the rescue device bracket 3, converting the extension and rotational motion of the mechanism into the lifting and translation of the bracket, achieving precise docking of the rescue device. The various components are connected by rotation to form a flexible and interconnected transmission system. The driving force of the hydraulic cylinder 4 is efficiently transmitted through the swing arm linkage mechanism 2. Combined with the attitude control of the horizontal adjustment rod 10, the loading and unloading of the rescue device can be completed quickly, meeting the dual requirements of operational efficiency and stability in emergency rescue. Its ease of operation reduces the over-reliance on the professional skills of rescue personnel. Even in complex and chaotic on-site environments, loading and unloading operations can be completed quickly, reducing delays caused by human error. At the same time, the device has a stable fixing and protection function, which can ensure the safety of equipment and materials during transportation and avoid damage caused by bumps and collisions.
