Abstract
Description
Technical Field
[0001] This utility model relates to the field of transportation vehicle technology, and in particular to an integrated carriage for a mining explosion-proof rubber-wheeled vehicle. Background Technology
[0002] Currently, most explosion-proof electric personnel transport vehicles used in underground coal mines still follow the design concept of diesel vehicles, with the personnel transport compartment and driver's cab being designed as separate units. The compartment and driver's cab are two enclosed and independent parts, separated by a partition, and the driver and passengers communicate via intercom. The electric rubber-tired vehicle's compartment and driver's cab are designed as separate units, roughly the same as diesel vehicles, failing to achieve the goal of lightweight design. The partition between the two occupies a certain amount of space, and the overall vehicle length is basically the same as that of the diesel vehicle. With the compartment and driver's cab separate and independent, and the driver and passengers only communicating via communication equipment, the driver cannot fully and promptly understand the situation inside the compartment, sometimes resulting in communication difficulties, and in serious cases, even safety hazards. Therefore, this utility model proposes an integrated compartment for an explosion-proof rubber-tired mining vehicle. Utility Model Content
[0003] The main purpose of this utility model is to provide an integrated car body for explosion-proof rubber-wheeled mining vehicles, which solves the problems of large vehicle space occupation, poor driving and communication, and safety hazards caused by the split car bodies mentioned in the background.
[0004] This utility model achieves the above-mentioned objective through the following technical solution: an integrated car body for a mining explosion-proof rubber-wheeled vehicle, comprising a body structural component and a body cover component located above the body structural component. The body structural component includes an integrated square steel frame, a front axle fixing part, and a rear axle fixing part. The body cover component includes an integrated front window frame, two door frames, a rear escape door frame, a bottom, and a top. The front window frame, the two door frames, the rear escape door frame, the bottom, and the top together form a car body. The car body includes a driver's cab and a passenger compartment connected to the driver's cab. The front axle fixing part is connected to the front of the square steel frame, and the rear axle fixing part is connected to the rear of the square steel frame. The front window frame is connected between the front axle fixing part and the top. The rear escape door fixing part is connected between the rear axle fixing part and the top. The door frames connect the bottom and the top from both sides.
[0005] Preferably, the front axle fixing part is provided with headlight fixing frames on both sides and front wheel mudguards located below the headlight fixing frames, and the headlight fixing frames are connected to the front window frame and the bottom.
[0006] Preferably, the rear axle fixing part is provided with arc-shaped rear wheel mudguards on both sides, and the rear wheel mudguards are connected to the bottom and the rear escape door frame.
[0007] Preferably, the top of the square steel frame is a mesh structure woven from multiple transverse square steels and multiple longitudinal square steels.
[0008] Preferably, the vehicle body structure further includes two seating areas, which are respectively located above the two rear wheel mudguards along the length of the square steel frame.
[0009] Preferably, the bottom end near the rear escape door fixing frame is provided with a step portion, and the step portion 241 is located between the two seating portions.
[0010] The beneficial effects of this utility model's technical solution are:
[0011] The integrated square steel frame allows the carriages to form a connected structure, thereby reducing the overall size of the explosion-proof rubber-wheeled vehicle and making it more flexible to drive; the driver's cab is connected to the passenger compartment, allowing passengers to communicate directly with the driver and avoiding safety hazards caused by poor communication.
[0012] The vehicle body panel includes two door frames and a rear escape door frame, thus forming three escape routes. Passengers can directly open the escape door from the rear escape door frame to escape, or enter the driver's cab and open the door from the door frame to escape, avoiding congestion and further improving the safety of the rubber-wheeled vehicle.
