Description

Lightning protection car modularization laminate flooring

Technical Field

The invention belongs to the technical field of wheel type mine anti-surge, and particularly relates to a modular composite floor which can reduce the damage of impact generated by mine explosion to passengers and improve the maintainability in a V-shaped cabin of a lightning protection vehicle.

Background

The bottom of the lightning protection vehicle is designed into a V shape in order to prevent the attack of other explosion devices such as mines and the like, and the vehicle body is of a totally-enclosed structure, the chassis and electrical components of the lightning protection vehicle are mostly arranged in a V-shaped cabin and a floor, the floor is required to be disassembled during maintenance, a maintenance point almost covers the whole floor, and the floor is provided with connecting pieces such as an operation part, a seat, a lifting mechanism, an air conditioning system and the like, so that great effort is required during maintenance. In addition, the conventional lightning protection vehicle and the floor material are made of multi-purpose steel plates, and impact caused by a vehicle body is transmitted rigidly during explosion, and the impact acceleration on the soles of soldiers greatly exceeds the tolerance limit of a human body. Therefore, the problems to be solved urgently in the field of the lightning protection vehicles at present are to reduce the impact of the floor on passengers during explosion and the rapid maintenance in wartime and to reduce the operation difficulty and strength.

Disclosure of Invention

The present invention is directed to overcoming the problems of the prior art, and to reduce the transfer of explosion energy from a floor to reduce casualties and to improve the maintenance performance of a mine protection vehicle to reduce the maintenance time in wartime and to improve the efficiency of combat.

The invention relates to a lightning-proof modular composite floor for preventing explosion impact and quick maintenance of a vehicle, which comprises:

and the floor framework is assembled on the vehicle body and positioned above the closed V-shaped cabin chassis component, and the framework comprises the whole floor surface and is used for bearing the floor panel.

The light high-strength composite floor panel is arranged along the length direction of a vehicle body, and the composite floor panel is assembled on the floor framework through a fastener.

The parts such as seats and the like assembled on the floor are assembled on the floor framework by penetrating the composite floor through fasteners.

Preferably, the fitting area above the entire floor surface is individually blocked to reduce the number of top fittings and removal.

Preferably, the floors of all parts needing maintenance in the whole V-shaped cabin are independently partitioned, so that the aims of minimum dismantling and quick maintenance are fulfilled.

Compared with the prior art, the invention has the following advantages and beneficial technical effects:

1. the floor is divided into blocks independently and modularly, so that independent and rapid overhaul of each maintenance part in the V-shaped cabin is guaranteed.

2. The connecting piece on the floor is divided into areas independently, so that the assembly and disassembly are reduced.

3. The novel composite material floor is light in weight, the surface density of the floor with the thickness of 10mm is less than 8kg, the disassembly strength can be greatly reduced, and a soldier can easily finish the disassembly of the whole floor.

4. The composite floor has the characteristic of small transmission vibration, can greatly buffer and reduce foot impact generated by explosion, and ensures the foot and life safety of soldiers.

Drawings

FIG. 2 is a front view of the present invention (general assembly view);

FIG. 3 is an isometric view of a modular composite floor.

Detailed Description

The invention will be further explained with reference to the drawings and examples.

Examples

The embodiment relates to a lightning-proof vehicle explosion impact prevention and rapid maintenance modular composite floor, as shown in fig. 1, which comprises a modular composite floor panel 1, a floor framework 2, a gearbox floor heat shield 3 and a transfer case floor heat shield 4. The floor framework 2 is assembled on the extension protection side plate 6 by adopting a countersunk head screw 5, so that the whole floor framework is flat and has no protrusion. The modular composite floor panel 1 is assembled on the floor framework by using countersunk head screws 5.

As shown in figure 2, the gearbox floor heat shield 3 is located at the front middle position of the whole floor and is assembled on the floor framework 2 by adopting a countersunk head screw 5, so that a good heat insulation effect is achieved. The transfer case floor heat shield 4 is located at the rear end of the gearbox floor heat shield 3 and is also installed on the floor framework 2 through the countersunk screws 5, the whole installation plane is uniform, sealing is smooth, and hot air and noise in the V-shaped cabin 7 can be well isolated.

As shown in fig. 3, which is an axial view of the entire modular composite floor, it can be seen that the plane of the entire modular composite floor is divided into modules according to actual conditions, so as to create simple and rapid maintenance conditions for the chassis and the electrical components in the V-shaped cabin 7.
