Description

Technical Field

[0001] The invention relates to the technical field of truck cabs, and in particular to an explosion-proof truck cab. Background Art

[0002] Freight vehicles are motor vehicles used to transport goods, including various types of trucks, trailers and other transport vehicles. These vehicles play a vital role in the transportation of goods, and are able to transport goods from one location to another; freight vehicles are usually composed of engines, transmission systems, frames, suspension systems, brake systems and cabs.

[0003] Generally, a large number of indicator lights, instruments, audio, air conditioning, control buttons and other electrical equipment are installed on the dashboard and center console of the truck cab to provide convenience for the driver during driving. In the workplaces with explosion-proof requirements commonly seen in mines, coal mines, petrochemicals and military industries, special explosion-proof trucks are often used to complete the transportation of goods in order to prevent explosion accidents. For explosion-proof trucks, their cabs should also meet the explosion-proof requirements of the workplace, while ordinary truck cabs are difficult to use in the above-mentioned places because they are equipped with a large number of non-explosion-proof electrical equipment. At present, the cabs of most explosion-proof trucks use ordinary truck cabs that have been modified from explosion-proof or open frame structure cabs. The former has the disadvantages of low specialization, high explosion-proof modification costs, and insufficient use of the space in the cab, while the latter has poor quietness and comfort in the cab. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a special driving cab for explosion-proof freight vehicles.

[0005] The technical solution provided by the present invention is: a special cab for explosion-proof freight vehicles, including an outer shell of the cab, wherein cab doors are respectively arranged on the two outer sides of the outer shell of the cab, a steering control device, a brake pedal and an accelerator pedal are respectively fixedly connected from left to right on the left side of the lower end of the inner shell of the cab, wherein the steering control device is composed of a steering column and a steering wheel, and an instrument panel is fixedly connected to the front side of the inner shell of the cab; the special feature is that a first explosion-proof knob and an explosion-proof display screen are respectively fixedly connected on the left side of the instrument panel from left to right; an electrical box is arranged on the right side of the lower end of the inner shell of the cab, wherein the first explosion-proof knob and the explosion-proof display screen are ... fixedly connected on the right side of the lower end of the inner shell of the cab, wherein the first explosion-proof knob and the explosion-proof display screen are fixedly connected on the left side of the instrument panel from left to right; an electrical box is fixedly connected on the right side of the lower end of the inner shell of the cab, wherein the first explosion-proof knob and the explosion-proof display screen are A chassis flameproof distribution box is fixedly connected to the left side of the lower end of the electrical box, and an upper flameproof distribution box and a flameproof control box are fixedly connected to the right side of the lower end of the electrical box from front to back. The chassis flameproof distribution box, the upper flameproof distribution box and the flameproof control box are all composed of a box body and a box cover made of aluminum alloy. The box body and the box cover are tightened and sealed by threaded connection. Several evenly arranged cable connectors are respectively arranged on the side walls of the chassis flameproof distribution box, the upper flameproof distribution box and the flameproof control box; the first explosion-proof knob and the explosion-proof display screen fixed on the left side of the instrument panel are respectively connected to the chassis flameproof distribution box through cables.

[0006] Furthermore, three wire holes are arranged in the middle of the bottom of the outer shell of the cab.

[0007] Furthermore, a button box is provided on the left side of the electrical box, a second explosion-proof knob is fixedly connected to the top of the button box, and the second explosion-proof knob is connected to the chassis explosion-proof distribution box through a cable.

[0008] Furthermore, a hinged and movable box door is provided on the top of the electrical box.

[0009] Furthermore, the coating of the outer casing of the cab is electrostatically conductive paint with low resistivity.

[0010] Beneficial effects of the present invention: 1. The cab is equipped with key components for the driver to control the vehicle, such as steering control device, brake pedal, accelerator pedal, explosion-proof display screen and explosion-proof knob, and all key components can meet the explosion-proof requirements for use in dangerous workplaces; 2. Compared with the cab of general freight vehicles, there is no co-pilot seat which is not very useful in short-distance transportation in explosion-proof workplaces. Instead, a chassis flameproof distribution box, a top flameproof distribution box and a flameproof control box are set on the right side of the driver's seat. By integrating the electrical equipment of the cab and vehicle chassis into the chassis flameproof distribution box, the top flameproof distribution box and the flameproof control box, the chassis layout space is saved, and the chassis wiring harness is highly integrated, which is convenient for the inspection and maintenance of chassis electrical appliances; 3. Adopt a variety of explosion-proof or flameproof measures, and use low-resistivity electrostatic conductive paint to greatly reduce the possibility of electric sparks generated in the cab during use, and significantly improve the safety of vehicle operation in explosion-related workplaces.
