Description

Technical Field

[0001] This utility model relates to the field of derailment control technology, specifically a suspended derailment control bar for mine cars that have derailed. Background Technology

[0002] In the mining and transportation of mineral resources, the safe operation of mining cars is a crucial link in ensuring production efficiency and personnel safety. However, due to various reasons such as track wear, operational errors, and equipment failures, mining car derailment accidents occur frequently, posing serious safety hazards to mine production. To address this issue, some derailment prevention devices have emerged on the market, designed to stop derailed mining cars and prevent them from continuing to slide and causing greater damage.

[0003] For example, Chinese patent CN212890355U discloses a retractable mine car stop. This device, through its retractable design, can be retracted when not in use, reducing the impact on the normal operation of mine cars and facilitating maintenance and repair. To a certain extent, this patented retractable mine car stop improves the flexibility and safety of mine transportation. Although this patent represents a certain advancement in mine rail car stops, it still has some shortcomings and limitations. Specifically, the blocking effect and adaptability of this patented car stop when dealing with mine cars of different weights and speeds derailing may still have room for improvement. Furthermore, although the device has a retractable function, the stability and reliability of the retraction process still need further optimization in actual operation. Therefore, we propose a suspended mine car stop based on mine car derailment. Utility Model Content

The top output end of the second sensor 19 is fixedly connected to the support column 11, and the top output end of the support column 11 is fixedly connected to the electric winch 12.

[0026] Furthermore, a crossbeam 18 is movably connected to the bottom output end of the support column 11. A rubber buffer plate 16 is in frictional contact with the output end of the crossbeam 18 on the side away from the support column 11.

A second fixed column 13 is fixedly connected to the bottom output end of the second support frame 14, and the second fixed column 13 is parallel to the fixed column 1.

[0027] Furthermore, the internal structure of the second fixed column 13 is the same as that of the fixed column 1.

[0028] Furthermore, a sensor 17 is fixedly connected to the bottom of the inner wall of the rubber buffer plate 16, and a second sensor 19 is fixedly connected to the output end of the crossbeam 18 near the rubber buffer plate 16, and the second sensor 19 is parallel to the sensor 17 vertically.

[0029] Furthermore, a second support column 15 is fixedly connected to the top output end of the second support frame 14, and a pulley 20 is movably connected to the top output end of the second support column 15.

The output end of the steel wire rope 21 away from the electric winch 12 is hung on the output end of the crossbeam 18 near the rubber buffer plate 16. Several fixed seats 22 are fixedly connected to one end of the top of the fixed column 1 and the second fixed column 13.

[0030] Furthermore, the support column 11, the second support column 15, and the crossbeam 18 are made of cold-welded seamless square steel. The support column 11 is 1.5 meters high, the second support column 15 is 2.6 meters high, and the crossbeam 18 is 5.7 meters long.

[0031] Working principle: The stop bar mainly consists of a fixed post 1, a fixed plate 2, a rotating plate 3, an arc-shaped limiting groove 4, a reinforcing anchor 5, a bevel gear 6, a bevel gear roller 7, a second bevel gear 8, and a forward / reverse motor 9. The fixed post 1 is connected to the rotating plate 3 through the fixed plate 2. The rotating plate 3 has an arc-shaped limiting groove 4. The reinforcing anchor 5 is connected to the arc-shaped limiting groove 4 through frictional contact, which enhances the stability of the structure. The bevel gear 6 meshes with the bevel gear roller 7 and the second bevel gear 8 to form a transmission mechanism. The forward / reverse motor 9... The support frame 10 is fixed to the top of the fixed column 1 and drives the second bevel gear 8 to rotate. When the forward and reverse motor 9 starts, its output end transmits power through the meshing of the second bevel gear 8, bevel gear roller 7, and bevel gear 6, causing the rotating disk 3 to rotate on the fixed disk 2. The rotation of the rotating disk 3 drives the reinforcing anchor 5 connected to it, further enhancing the stability of the entire structure. The electric winch 12 is connected to the crossbeam 18 through the steel wire rope 21. The other side of the crossbeam 18 is in frictional contact with the rubber buffer plate 16. When the mine car detaches... When the rail impacts the rubber buffer plate 16, the impact force is absorbed by the rubber buffer plate 16 and transmitted to the crossbeam 18. The crossbeam 18 transmits the force to the electric winch 12 through the steel wire rope 21. At the same time, the pulley 20 acts as a guide. The bottom of the inner wall of the rubber buffer plate 16 is equipped with a sensor 17, and the crossbeam 18 is equipped with a second sensor 19. The two are parallel to each other. When the distance between the sensor 17 and the second sensor 19 increases, a signal is sent to the electric winch 12 to control it to stop rising or start falling, thereby avoiding damage to the steel wire rope due to excessive stretching or causing safety accidents. Key components such as the support column 11, the second support column 15, and the crossbeam 18 are made of cold-jointed seamless square steel to ensure the strength and stability of the structure. The support column 11 is 1.5 meters high, the second support column 15 is 2.6 meters high, and the crossbeam 18 is 5.7 meters long. These dimensions ensure that the stop bar can effectively intercept and buffer the impact force of the derailed mine car. The fixed column 1 and the second fixed column 13 are equipped with several fixed seats 22 for reinforcing both sides of the device.
