Police climbing assault vehicle

Abstract

The invention discloses a police climbing assault vehicle, which includes a driver's cab and a car chassis, and is characterized in that the top-mounted support truss is formed by interconnecting a truss main body, a front outrigger at the front end of the truss main body, and a rear outrigger at the rear end of the truss main body. The main body of the truss is equipped with a ladder moving platform, a driving device and an assembly platform. An assembly platform is provided at the rear half above the main body of the truss. Both sides of the assembly platform are fixedly connected with the longitudinal beams respectively. The two sides of the ladder frame mobile platform are slidingly connected with the horizontal slide rails through the rollers, and the upper ends of the ladder frame mobile platform are respectively hinged with the lifting device and the extension ladder frame, so that the climbing ladder frame, lifting device and The center of gravity of the ladder frame mobile platform can move forward and backward by 2.4 meters, reducing the front axle load by 300-500kg, which meets the axle load distribution requirements of different automobile chassis, and has the advantages of novel structure, reasonable axle load distribution, stability and reliability, etc.

Description

technical field [0001] The invention relates to the technical field of police equipment, in particular to a police climbing assault vehicle. Background technique [0002] At present, the police climbing assault vehicle usually adopts a support truss set on the automobile chassis, and a pitchable and telescopic climbing ladder frame is set on the support truss. For example, Chinese patent CN201173085Y discloses a climbing assault vehicle for anti-terrorism operations, which includes The car body, the car body is composed of a car chassis and a cockpit, the car chassis is provided with a member carrying compartment, and the top of the member carrying compartment is provided with a workbench for carrying people, and the workbench for carrying people is provided by an elevator at the front end. It is composed of a fixed platform at the rear end, the elevator is connected to the telescopic oil cylinder, the telescopic oil cylinder is connected to the hydraulic control system, the...

Problems solved by technology

[0002] At present, the police climbing assault vehicle usually adopts a support truss set on the automobile chassis, and a pitchable and telescopic climbing ladder frame is set on the support truss. For example, Chinese patent CN201173085Y discloses a climbing assault vehicle for anti-terrorism operations, which includes The car body, the car body is composed of a car chassis and a cockpit, the car chassis is provided with a member carrying compartment, and the top of the member carrying compartment is provided with a workbench for carrying people, and the workbench for carrying people is provided by an elevator at the front end. It is composed of a fixed platform at the rear end, the elevator is connected to the telescopic oil cylinder, the telescopic oil cylinder is connected to the hydraulic control system, the hydraulic control system is installed on the chassis of the car, and the two sides of the rear side of the manned workbench are respectively equipped with side climbers. There is a rear climbing ladder at the rear of the manned workbench. The substantive disadvantages of this structure are: first, the load of the lift at the front is entirely carried by the front end of the car chassis, which makes the front axle load of the car chassis too heavy. Affect the driving performance of the vehicle; Second, due to the limited support of the elevator, it cannot meet the requirements of multiple special police soldiers passing through at the same time.

[0003] Aiming at the second deficiency, Chinese patent CN1730373A discloses a multifunctional assault truss applied to vehicles, which includes the main body of the truss as a ladder moving platform at the front and an assembly platform at the rear, and a non-slip floor is laid on the walking surface , the ladder mobile platform includes a lifting slope driven by a power assembly to rotate and lift and an extension slope installed in the lifting slope along the lifting slope. The assault truss is connected with the car chassis connector and the car body. This climbing The lifting slope of the device is installed on the fixed truss on both sides through the rotating shaft. The power component is a T-shaped triangle lifting mechanism. The extending slope is installed in the lifting slope and driven by a two-way horizontal push cylinder. The slope is 37 degrees, and the connection of the car chassis is fixed by drawing and fixing the bolt-free rectangular pipe. The lower end of the truss is supported by outriggers, and there are no strengthening measures between adjacent outriggers, which will easily cause the top-mounted truss to tilt during combat, resulting in poor safety performance; third, because the outriggers are fixed on the car chassis, when the front end of the car chassis When the weight is suddenly increased, it will cause the chassis of the car to tilt forward to varying degrees, which affects the safety of the combat personnel on the upper body truss
