Description

Technical Field

[0001] The utility model relates to the technical field of monorail cranes, in particular to a personnel getting-on-and-off device for a monorail locomotive used in coal mines. Background Technique

[0002] In order to improve production efficiency, at present, many coal mines use monorail locomotives equipped with personnel carriers to transport workers underground. The monorail crane uses a special I-beam hung in the air in the roadway as a track, and a series of hanging vehicles with various functions are connected into a vehicle group, which is towed by a traction device and runs along the track.

[0003] Publication No. CN217950247U discloses a ladder device for a monorail locomotive. The patentee pulls a pull block through a groove, and the pull block drives a moving gear sleeve to move through a pull rod. The moving gear sleeve compresses a clamping spring, so that the moving gear sleeve is disengaged from the rotating gear. When the moving gear sleeve moves, it drives a moving block to move through a connecting rod, and the moving block drives a movable rod to move, compressing a return spring, so that the limiting gear sleeve is disengaged from the limiting gear, so that the ladder can rotate along the first fixing block and the second fixing block, and the ladder moves downward, facilitating the user to climb. However, the following problems still exist in the actual use of this patent:

[0021] 2. When one side of the movable rod moves, it can drive one side of the L-shaped rod to slide on the positioning frame. After one side of the L-shaped rod moves, it can drive the rotating member to rotate through the rotating rod. After the rotating member rotates, it can push the other side of the L-shaped rod to move through the other rotating rod. When the movable plate moves downward to drive one side of the movable rod to move, the two movable rods can move away from each other at the same time, so that the teeth on the two arc plates leave the limiting gear. The limiting gear can be positioned more firmly by the two groups of teeth, and the two arc plates can move away at the same time, which is convenient for operation and improves the practicality.

[0031] Working principle: Before using this personnel getting on and off device for a single-track hoisting locomotive in coal mines, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 5As shown in the figure, a ladder component 2 is provided on one side of the cab 1 where the support plate 101 is located. When the ladder body 202 is lowered or retracted, the movable plate 212 is pressed. After the movable plate 212 moves downward, the limit rod 219 can slide inside the connection groove 220, so that the limit rod 219 can be pushed to slide on the limit block 218. After the limit rod 219 moves, it can drive the moving plate 214 to move through the connecting rod 213, and the tension spring 216 can be stretched. The downward movement of the movable plate 212 can drive the connecting rod 213 to rotate. After the connecting rod 213 rotates, it can push the movable rod 205 to slide on the mounting block 204, so that the telescopic spring 209 can be compressed, and the teeth 208 on the arc plate 207 are disengaged from the limit gear 206, so that the limit gear 206 loses its limit and the ladder body 202 can be rotated. The ladder body 202 can be retracted or lowered. After the movable plate 212 moves downward along the positioning rod 217, the limit rod 221 is aligned with the limit groove 219. Under the action of the tension spring 216, the limit rod 219 is engaged with the limit groove 221, so that the movable plate 212 is positioned. Furthermore, the movable rod 205 can be positioned, so that the movable plate 212 can be automatically positioned after moving downward, avoiding the need to continuously press the movable plate 212 when rotating the ladder body 202, which is convenient for subsequent rotation of the ladder body 202. After the ladder body 202 rotates, the moving plate 214 is pressed so that the limit rod 219 is disengaged from the limit groove 221, and the movable plate 212 loses its limit. The telescopic spring 209 returns to its deformed state to position the limit gear 206, and then the ladder body 202 is positioned. The ladder component 2 facilitates the driver to get on and off the cab 1, and is convenient for lowering and retracting the ladder body 202, which is convenient for the user to use and improves the convenience and practicality;

[0032] While one side movable rod 205 moves, it can drive one side L-shaped rod 223 to slide on the positioning frame 224. After the one side L-shaped rod 223 moves, it can drive the rotating part 225 to rotate through the rotating rod 226. After the rotating part 225 rotates, it can push the other side L-shaped rod 223 to move through the other side rotating rod 226. When the movable plate 212 moves downward to drive the one side movable rod 205 to move, the two movable rods 205 can move away from each other at the same time, so that the teeth 208 on the two arc plates 207 leave the limit gear 206. The limit gear 206 can be more firmly positioned by the two sets of teeth 208, and the two arc plates 207 can move away from each other at the same time, which is convenient for operation and improves the practicality.

[0033] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described 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 utility model shall be included within the protection scope of the present utility model.
