Description

Technical Field

[0001] This utility model relates to an emergency rescue device for compressed liquefied gas. Background Technology

[0002] Chinese patent application number 202322028749.4 discloses an emergency rescue device for compressed liquefied gas. By integrating a storage tank, compressor, and suction pump onto a vehicle, it can be driven to the site of an LPG leak for rescue. However, such emergency rescue devices are relatively large and not suitable for complex environments or narrow roads. Therefore, they are usually moved to the accident site by towing, as shown in patents 201921207822.1 and 201920416479.5.

[0003] The emergency transfer device for compressed liquefied gas differs from conventional devices used only for transporting related maintenance equipment. The weight of its storage tank differs before and after the transfer, resulting in a different center of gravity for the rescue device and poor stability when the emergency rescue device is towed. Furthermore, the aforementioned rescue device uses only one pair of wheels, which leads to even worse stability at more complex intersections or at high speeds. Utility Model Content

[0004] The purpose of this invention is to provide an emergency rescue device that can improve stability during movement and reduce the possibility of tipping over after rescue.

[0005] To achieve the above objectives, this utility model employs an emergency rescue device, including a chassis with a connector and wheels on both sides. The connector is located at the front end of the chassis. The front of the chassis has a front accommodating space for accommodating a storage tank. The rear of the chassis has front and rear limiting baffles extending upwards at its front and rear ends, respectively, forming an upward-opening rear accommodating space. A housing integrating emergency equipment is fixed in the rear accommodating space. The wheels include front and rear wheels, located on the left and right sides of the rear accommodating space, respectively. At least the front of the chassis has a liftable support leg, which is fixed to a rotating component. The rotating component is rotatably fixed to a fixed component. The fixed component is formed or disposed on the front. The rotating component and the fixed component have mutually cooperating holes and are equipped with positioning pins for inserting into the cooperating holes.

[0006] The front of this utility model is used to fix the storage tank, and the rear is used to fix the box housing integrated with emergency equipment such as compressors and motors. Before the emergency rescue is completed, that is, when the storage tank is empty, the chassis of this utility model is lighter, which can reduce the fuel consumption, braking consumption and wear of the tractor, reduce the burden on the tractor, and help extend the service life of the tractor. After the emergency rescue is completed, that is, when the storage tank is filled with liquefied gas, the center of gravity will be closer to the tractor, making it easier for the trailer to maintain stability during driving, reducing the risk of swaying and overturning, improving safety during use, reducing the inertial force of the trailer when turning or changing lanes, making it easier for the trailer to follow the driving trajectory of the tractor, and improving maneuverability.

[0007] The front and rear limit baffles restrict the forward and backward movement of the container, preventing it from falling or colliding with the storage tank. When the container is welded to the chassis, the front and rear limit baffles also serve a positioning function. This invention features wheels on both the left and right sides of the front and rear ends of the container, with the front wheels positioned close to the storage tank, which improves the stability of the chassis support and further ensures the stability of the invention during use.

[0008] By incorporating support legs, this invention allows for the disconnection of the invention from the vehicle after it has been towed to the accident location. The support legs can then be lowered to provide adequate support for the invention, reducing swaying during liquid absorption and improving the stability of the device during use.

[0009] The support leg of this invention can be rotated and retracted, facilitating towing by a tractor. This is achieved by rotating the support leg and inserting a positioning pin into the mating holes of the rotating and fixed components. The support leg is height-adjustable, shortening by retraction to prevent contact with the ground or other obstacles during rotation; its height can also be adjusted by extension to support uneven ground. When the support leg is vertical, the mating holes of the rotating and fixed components are not coaxial. When the support leg and rotating component rotate to a set position, the mating holes of the rotating and fixed components become coaxial and connected. The positioning pin is connected to the support leg, rotating component, chassis, or fixed component via a rope or other connecting component.

[0010] Preferably, the rotating component is provided with an elastic pin, and the fixing component is provided with a positioning hole corresponding to the elastic pin. When the support leg is vertical, the positioning hole is aligned with the elastic pin. When the support leg is vertical, the elastic pin and the positioning hole are aligned, which can quickly fix the support leg in a vertical position, ensuring that it will not loosen or shift during use and improving the stability of the device.

[0011] Preferably, the fixing component includes a fixing plate and at least one clamping plate. The fixing plate has first fastening bolts at its four corners, each fitted with a nut. Each clamping plate corresponds to at least two of the first fastening bolts at two corners of the fixing plate. The front portion has several extension sections extending in the front-rear direction. When the fixing component is fixed to the front portion, the extension sections are located between the first fastening bolts on the upper side of the fixing plate and the first fastening bolts on the lower side of the fixing plate. This configuration facilitates the assembly and disassembly of the support leg of this invention without requiring significant changes to the chassis structure.

[0012] Preferably, a second fastening bolt is threaded onto the clamping plate, the end of which abuts against the side wall of the extension section. This arrangement further improves the fixation effect of the support leg.

[0013] Preferably, the front part includes a first front part with the connector fixed at the front end and inclined, and a second front part with the same height as the rear part. The second front part is provided with the support leg, and a front receiving space for accommodating the storage tank is provided at the second front part. The length of the second front part in the front-rear direction is at least half that of the rear part in the front-rear direction.

[0014] Preferably, the support leg located at the second front part is positioned closer to the first front part. This arrangement improves the stability of the storage tank of this invention when pumping liquid from an accident vehicle.

[0015] This invention has the advantage of improving the stability and safety of emergency rescue devices used for compressed liquefied gases. Attached Figure Description
