Description

Technical Field

[0001] The utility model belongs to the technical field of unloading type mine cars, in particular to a single-side curved track side-unloading type mine car. Background Art

[0002] The single-side curved track side-unloading mine car is referred to as the curved track side-unloading mine car. The side-unloading mine car is a special type of vehicle used to transport ore or other bulk materials. Its structural characteristics and working principle make it very suitable for use in mines and industrial and mining enterprises. During the movement of the mine car, the unloading wheel arm passes through the unloading curved track to realize the automatic tipping and automatic reset of the carriage. It is highly efficient, safe and reliable. The unloading is carried out under the traction of the locomotive. When the unloading wheel climbs onto the curved track, the carriage flips over and the door automatically opens to unload. After the car passes the curved track, the carriage returns to its original position and the door is automatically locked.

[0003] In contrast, the Chinese patent with announcement number CN209617137U discloses a new type of single-sided curved track side-unloading mining car, including a car and a connecting frame, a car head connecting part is arranged at the bottom front of the car, a car frame is arranged at the bottom of the car, a capstan is arranged at the upper right side of the frame, an axle is arranged at the bottom of the frame, a wheel is connected to the axle, a fixed side door is arranged on the left side of the car, a movable side door is arranged on the right side of the car, a fixed frame is installed in the middle of the upper part of the fixed side door, a limiting block is arranged at the lower part of the fixed frame, the fixed frame is connected to a movable wheel, the movable wheel is connected to a connecting piece, the connecting piece is connected to a dumping wheel, fixed lock buckles are arranged on both sides of the bottom of the movable side door, a movable lock buckle is arranged on the right side of the bottom of the front surface of the car, the movable lock buckle is connected to the connecting frame, a fixing rod is arranged on the connecting frame, the fixing rod is connected to the movable wheel, and a limiting bolt is arranged at the bottom of the left side of the front surface of the car.

[0004] However, the above patent adopts a direct push rollover setting, which has poor stability and a small rollover angle, and uses a locking hook to close the side door, which is easily squeezed by the gravity of the ore and causes unhooking, so a new device needs to be designed.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-3 , a single-sided curved-rail side-dumping mine car, including a frame body 3, four mine car wheels 10 are symmetrically installed on both sides of the bottom of the frame body 3, a number of second supports 13 are evenly distributed on the frame body 3, a car body 1 is hinged on the second support 13, a pulley 7 is installed at the bottom of one side of the car body 1 away from the second support 13, and further includes two first supports 8 symmetrically installed on one side of the frame body 3 away from the second support 13, two connecting rod frames 2 are symmetrically installed at both ends of the car body 1, the middle of the connecting rod frame 2 is hinged to the top of the car body 1, the bottom end of the connecting rod frame 2 is hinged to the first support 8, a car door 4 is installed between the top ends of the two connecting rod frames 2, a balance wheel 5 is installed in the middle of the bottom of one side of the frame body 3 away from the second support 13, buffer frames 6 are symmetrically arranged at both ends of the frame body 3, a buffer head 11 is installed in the middle of the buffer frame 6, a buffer spring 14 is installed between the buffer head 11 and the buffer frame 6, a bolt 9 is installed on the buffer head 11, a three-ring chain 12 is arranged in the middle of the buffer head 11, and the bolt 9 passes through the buffer head 11 and the three-ring chain 12.

[0024] Furthermore: the tilting angle of the carriage body 1 is not less than 42 degrees, which ensures the thoroughness of the ore dumping; the balance wheel 5 is rotatably connected to the frame body 3, and the pulley 7 is rotatably connected to the carriage body 1, which ensures the flexible rotation of the balance wheel 5 and the pulley 7; the first support 8 and the second support 13 are respectively bolted to the frame body 3, which is convenient for disassembly and replacement of the first support 8 and the second support 13; the buffer frame 6 and the frame body 3 are riveted together to avoid pulling off the car, and the carriage door 4 and the connecting rod frame 2 are welded together to ensure stability and reliability; the buffer head 11 is made of ZG35B steel material, and the end is fan-shaped to ensure firmness; the mine wheel 10 is connected to the frame body 3 by bearings to ensure flexible rotation of the mine wheel 10.

[0025] Working principle: the carriage body 1 is filled with ore, and under the action of gravity, the connecting rod frame 2 is pressed down to drive the carriage door 4 to close closely against the carriage body 1, and the pin 9 passes through the three-ring chain 12 and the buffer head 11, so that the three-ring chain 12 pulls the frame body 3 through the buffer head 11 and the buffer frame 6 to move along the track to support the carriage body 1 under the support of the mine wheel 10. When the buffer head 11 is under pressure, the buffer spring 14 is compressed to reduce the damage caused by mutual collision. When passing through the curved track, the balance wheel 5 prevents the frame body 3 from tipping over under the limit of the straight track, and the pulley 7 rises under the limit of the curved track, pushing the carriage body 1 to tip over under the support of the second support 13. At the same time, the carriage body 1 pulls the connecting rod frame 2 to move and open the carriage door 4 under the support of the first support 8 to ensure that the ore is poured out of the carriage body 1.
