Description

Technical Field

[0001] The utility model relates to the technical field of mining, and particularly relates to a side-dumping mine car with a limiting structure. Background Art

[0002] The side-dumping mine car is the main equipment for long-distance transportation in the horizontal roadway of the mine. It has a high running speed, a large adhesive weight, and is used in metal and non-metal mines. The walking part adopts a four-axle and eight-wheel mechanism, and a bogie structure is adopted between the axle and the car body frame, which reduces the turning radius of the mine car, effectively reduces the wear between the wheels and the track, and at the same time avoids the occurrence of derailment of the mine car. The connecting device between the mine cars is designed with a rubber buffer, which effectively reduces the impact force during the operation of the mine car.

[0003] When the mine car passes through the unloading station, the supporting wheels of the unloading station support on the wing plates of the mine car, and the car body frame and the wheel set are not stressed. While the mine car passes through the unloading station under the traction force, the unloading wheels on the car body frame (car door) descend along the unloading curved rail, and the materials are unloaded. During the whole unloading process, the bogie rotates along the trajectory with a maximum rotation angle of 8 degrees through the spindle and the limiting block of the car body frame, the car body frame rises and closes along the curved rail, and the wheels touch the rail and leave the unloading station to complete one unloading. During the ore unloading process, the spindle and the limiting block of the car body frame contact frequently and are easily damaged. The bogie will rotate 360 degrees, which has a great impact on the unloading station and seriously affects the service life of the unloading station. More seriously, when the inertia of the train is insufficient, it will stop at the unloading station, and it is more difficult to handle the accident. Therefore, this application provides a side-dumping mine car with a limiting structure to meet the requirements. Content of the Utility Model

Detailed implementation manners

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment: Refer to Figure 2 A side-dumping mine car with a limiting structure as shown, including a bogie 2 equipped with a wheel set 5, a car body frame 3 equipped with an unloading wheel 4 and the bogie 2, a carriage 1 is installed on the car body frame 3, connecting plates 7 are arranged at the front and rear ends of the car body frame 3, and bolts 6 are installed on the connecting plates 7. It also includes a limiting unit 8 to limit the wheels of the wheel set 5 and prevent the bogie 2 from rotating 360°.

[0025] As a preferred implementation manner in this embodiment, as shown in Figure 2-4As shown, the limiting unit 8 includes a hollow column 81, a limiting column 82, a driving screw 84, a square rod 85 and a rotating rod 86;

[0026] The hollow column 81 is welded to the cross beam of the vehicle chassis 3. The limiting column 82 is slidably arranged in the inner cavity of the hollow column 81 through a slider 83. The driving screw 84 is threadedly connected to the limiting column 82. The driving screw 84 is rotatably arranged in the inner cavity of the hollow column 81. One end of the square rod 85 is connected to the rotating rod 86, and the other end of the square rod 85 is slidably arranged in the sliding cavity of the driving screw 84. One end of the rotating rod 86 penetrates through the hollow column 81;

[0027] First mounting plates 88 and second mounting plates 89 are respectively fixedly sleeved on the outer walls of the driving screw 84 and the square rod 85. First magnetic rings 810 and second magnetic rings 811 are respectively arranged on the first mounting plates 88 and the second mounting plates 89. The opposite ends of the first magnetic ring 810 and the second magnetic ring 811 have opposite magnetic poles.

[0028] To adjust the distance between the limiting column 82 and the wheel, the rotating rod 86 can be pulled outwards, so that the first magnetic ring 810 is separated from the second magnetic ring 811, and the magnetic fixation between the driving screw 84 and the square rod 85 is released. At this time, the rotating rod 86 rotates, and the driving screw 84 is driven to rotate through the square rod 85, so that the limiting column 82 extends outwards or contracts inwards. After the distance adjustment is completed, the rotating rod 86 is squeezed so that the first magnetic ring 810 contacts the second magnetic ring 811 to form magnetic fixation, thereby preventing the rotating rod 86 from rotating self. When the bogie 2 rotates, the bogie 2 can be effectively prevented from rotating 360 degrees by the blocking and limiting of the wheel by the limiting column 82.

[0029] It should be noted that, first, a retaining piece 87 is fixedly sleeved on the part of the rotating rod 86 located inside the hollow column 81, which can prevent the rotating rod 87 from directly driving the square rod 85 to move out of the hollow column 81; second, at least two limiting units 8 are arranged on each bogie 2, and the two limiting units are arranged on both sides, so that the bogie 2 can contact the limiting unit 8 to form a block no matter which side it rotates towards.

[0030] As a preferred implementation manner in this embodiment, as Figure 3 shown, a universal ball 814 is installed on the end of the limiting column 82 penetrating through the hollow column 81.

[0031] The friction loss between the moving wheel and the limiting column 82 can be reduced through the universal ball 814.

[0032] As a preferred implementation manner in this embodiment, as Figure 3As shown, a welding block 812 is installed on the outer wall of the hollow column 81, and when the welding block 812 is installed, it is arranged near one end of the wheel on the wheel set 5. A welding bevel 813 is provided on the welding block 812.

[0033] During installation, first cut a round hole in the cross beam that is adapted to the size of the hollow column 81. Pass one end of the hollow column 81 through this round hole. The welding block 12 thereon forms a block with the cross beam. At this time, weld the welding block 12 to the cross beam. The welding block 812 is arranged near one end of the wheel on the wheel set 5 when installed. The purpose is to prevent the welded welding block 12 from falling off due to the impact from the wheel (the rotation of the bogie 2 causes the wheel to impact the limit column 81). By contacting the cross beam through the welding block 12 to form a support, it can effectively prevent the hollow column 81 from being impacted and causing impact cracks at the welded joint, improving the stability of component installation. The setting of its welding bevel 813 increases the contact area between the solder and the welding block 12, thereby improving the welding firmness.

[0034] As a preferred implementation manner in this embodiment, as Figure 3 shown, the included angle between the welding bevel 813 and the horizontal line is set to be 40° to 60°.

[0035] Setting the included angle within this range provides a large enough welding space for welding and also enables a relatively thick weld layer to be formed (improving the welding firmness).

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
