Description

Technical Field

[0001] The utility model relates to the technical field of mining vehicles, in particular to an impact-resistant mining vehicle cab. Background Art

[0002] A special vehicle for rail transportation in mines. To adapt to the narrow conditions of underground tunnels, the external dimensions are compact. There are trucks, man-carriages, material cars, etc. Mine cars are narrow-gauge railway transport vehicles used to transport bulk materials such as coal, ore and waste rock in mines. They are generally towed by locomotives or winches. Mine cars are divided into five categories according to their structure and unloading methods: fixed mine cars, dump mine cars, single-side curved track side-unloading mine cars, bottom-unloading mine cars and shuttle mine cars.

[0003] Mine cars generally travel on roads with poor conditions, and there is a possibility of rockfall at any time in the mountains, which makes the driving of mine cars very dangerous. In order to protect the safety of drivers, a mine car cab with strong impact resistance is required. The top of the existing mine car cab adopts an ordinary steel plate structure. When large pieces of falling rocks fall and hit the roof, it is difficult to resist the strong impact force, which will endanger the safety of the driver. Utility Model Content

In order to protect the safety of the driver, a mine car cab with strong impact resistance is needed. The top of the existing mine car cab adopts an ordinary steel plate structure. When large pieces of falling rocks fall and hit the roof, it is difficult to resist the strong impact force, which will endanger the safety of the driver.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A crash-resistant mining truck cab comprises a cab body, a windshield is fixedly connected to the side wall of the cab body, foot openings are provided on the opposite side walls of the cab body, a driving seat is fixedly arranged inside the cab body, a bearing plate is fixedly connected to the inner bottom surface of the cab body, a bottom support plate is fixedly arranged on the top of the bearing plate, the driving seat is fixedly connected to the top of the bottom support plate, two mounting columns are symmetrically fixedly connected to the top of the cab body, two plug-in columns are symmetrically slidably plugged in the two mounting columns, a sliding rod is slidably sleeved in the plug-in columns, the top end of the sliding rod is fixedly connected to a top cover plate, and the material of the top cover plate is boron steel.

[0007] Furthermore, a plurality of sliding holes are symmetrically formed in the bearing plate, and a support seat is slidably connected in each of the plurality of sliding holes. The top end of the support seat is fixedly connected to the bottom of the bottom support plate. A shock-absorbing spring is fixedly connected to the bottom of the support seat, and a rubber pad is fixedly connected to the bottom of the bottom support plate.

[0008] Furthermore, two slide rails are fixedly connected to the opposite side walls of the cab body. A sliding column is slidably sleeved outside each of the two slide rails. A door panel is fixedly connected between the two sliding columns. A pulling handle is fixedly connected to the side wall of the door panel. An iron bar is fixedly connected to the side wall of the door panel. Bent columns are fixedly connected to the opposite side walls of the door panel, and an electromagnet is fixedly connected in the bent column.

[0009] Furthermore, a sealing strip is fixedly arranged at the end of the door panel.

[0010] Furthermore, a buffer spring is fixedly connected to the bottom end of the sliding rod, and two locking rods that are screwed and inserted with the insertion column are symmetrically screwed and connected to the mounting column.

[0011] Furthermore, a U-shaped plate is fixedly connected to the side wall of the cab body. Two limit insertion plates are symmetrically inserted into the U-shaped plate. An anti-collision beam is fixedly connected between the two limit insertion plates. A plurality of air bags are fixedly connected at equal intervals on the inner wall of the anti-collision beam. The material of the anti-collision beam is aluminum alloy.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By providing a top cover plate made of boron steel on the top of the mining truck cab, the impact destructive force caused by falling rocks can be reduced, preventing the cab from being severely deformed, thereby avoiding life threats to the driver. During installation, the top cover plate can be lifted, so that the four insertion columns at the bottom of the top cover plate can be inserted into the installation column, and then the locking rod is rotated to lock the insertion column and the installation column, improving the installation speed of the top cover plate.

[0014] 2. The door panel is pulled by the pulling handle to slide on the slide rail to open the door. When the door is closed, the electromagnet in the bent column can attract the iron bar to fit together after being energized, so as to realize automatic closing, preventing gaps between the door and the cab door frame. Since there is a lot of dust in the working environment of the mining truck, improving the sealing between the door and the cab can prevent dust from entering the cab through the gap and affecting the driver, resulting in poor visibility due to the windshield being full of dust.

[0015] 3. A collision avoidance beam is provided at the front position of the cab body, and an airbag is connected to the side wall of the collision avoidance beam. In this way, when an accidental impact occurs to the cab, the impact force on the cab body can be reduced. The airbag absorbs a part of the impact force first, protecting the overall frame structure of the cab, thereby improving the impact resistance of the cab. BRIEF DESCRIPTION OF THE DRAWINGS

The top of the cab body 101 is fixedly connected, and two mounting columns 305 are symmetrically fixedly connected to the top of the two mounting columns 305, and two plug-in columns 304 are symmetrically slidably plugged in. The plug-in columns 304 are slidably sleeved with sliding rods 302, and the top of the sliding rod 302 is fixedly connected to a top cover plate 301, and the material of the top cover plate 301 is boron steel; the bottom end of the sliding rod 302 is fixedly connected to a buffer spring 303, and the mounting columns 305 are symmetrically screwed and connected with two locking rods 306 that are screwed and plugged with the plug-in columns 304.

[0025] Specifically, by providing a boron steel top cover plate 301 on the top of the mine car cab, the impact and destructive force caused by falling rocks can be reduced, and the cab can be prevented from being severely deformed, thereby preventing the driver from being threatened with life. During installation, the top cover plate 301 can be lifted so that the four plug-in columns 304 at the bottom of the top cover plate 301 can be inserted into the installation columns 305, and then the locking rod 306 is rotated to lock the plug-in columns 304 and the installation columns 305, thereby improving the installation speed of the top cover plate 301. In addition, by providing a sliding rod 302 and a buffer spring 303, the vibration effect caused by small pieces of falling rocks can be reduced, and the cab will not be shaken, thereby protecting the driver's driving safety.

[0026] Embodiment 1

[0031] During specific implementation, the door panel 203 is pulled by the pulling handle 204 to slide on the slide rail 201 to open the door. When the door is closed, the electromagnet 207 in the bent column 206 can attract the iron bar 205 to fit together after being energized, so as to realize automatic closing and prevent gaps between the door and the cab door frame. Since there is a lot of dust in the working environment of the mining truck, improving the sealing between the door and the cab can prevent dust from entering the cab through the gaps and affecting the driver, resulting in poor visibility caused by the windshield being full of dust.
