AI Technical Summary
The existing connection between track plates and track frames generally uses bolts and nuts for fastening. This makes the nuts prone to loosening under high-frequency vibration of the track chassis, causing the track plates to shift or fall off, increasing the risk of equipment downtime and safety accidents.
The annular groove of the fixed column is mechanically locked by wrapping steel wire around it, and the annular groove of the screw is also tightened by the nut and washer, forming a double anti-loosening mechanism to enhance the vibration resistance of the connection.
It effectively limits the relative rotation between the nut and the screw, avoids nut loosening due to high-frequency vibration, reduces the risk of track plate misalignment and detachment, and improves equipment operation stability.

[0026] Please see Figures 1-4 This utility model provides a technical solution: a quick splicing and replacement device for tracked chassis track plates, comprising:
[0027] The chassis body 1 and the track body 15 are mounted on the outside of the chassis body 1.
[0028] Replace the anti-slip structure, which is located on the track body 15;
[0029] The replacement anti-detachment structure includes track plate 2, connecting protrusion 5, screw 4, nut 9 and washer 12. The connecting protrusion 5 is fixedly connected to one side of track plate 2. The side of the connecting protrusion 5 away from track plate 2 is set as an arc structure. A connecting groove 6 is opened on the side of track plate 2 away from connecting protrusion 5. A through hole 7 is opened on one side of connecting protrusion 5. A through hole 10 is opened on one side of track plate 2. The through hole 10 communicates with the interior of the connecting groove 6. Screw 4 passes through the interior of through hole 10. Washer 12 is sleeved on the outer surface of screw 4. Nut 9 is threaded onto the threaded end of screw 4. An annular groove 13 is opened on the outer surface of screw 4. A wire hole 14 is opened inside the annular groove 13.
[0030] The replacement anti-detachment structure also includes a fixing post 8. An annular groove 11 is provided on the outer surface of the fixing post 8. A steel wire is wound inside the annular groove 11. The end of the steel wire away from the fixing post 8 passes through the inside of the wire hole 14 and is wound inside the annular groove 13.
[0031] The number of replaceable anti-slip structures is multiple. Multiple replaceable anti-slip structures are spliced together and installed on the outside of the chassis body 1. The track body 15 is composed of multiple replaceable anti-slip structures. The connecting protrusions 5 on the track plate 2 are installed in the connecting grooves 6 in the adjacent track plate 2 through the screws 4. The screws 4 are rotatably connected to the inside of the corresponding through hole 7. Two protrusions 3 are fixedly connected to the top of the track plate 2.
[0032] Furthermore, when using this device, a connecting protrusion 5 of a track plate 2 is inserted into the connecting groove 6 of an adjacent track plate, so that the through hole 7 of the connecting protrusion 5 is aligned with the through hole 10 of the track plate 2. The screw 4 passes through the through hole 10 and the through hole 7, and is tightened and fixed by the nut 9 and the washer 12. At this time, the annular groove 13 of the screw 4 corresponds to the annular groove 11 of the fixing post 8.
[0033] A steel wire is wound in the annular groove 11 of the fixed column 8. One end of the steel wire passes through the wire hole 14 of the screw 4 and is wound in the annular groove 13 and tightened. The cross-winding of the steel wire forms a mechanical lock, which restricts the relative rotation of the nut 9 and the screw 4. When the track chassis vibrates while driving, the tension of the steel wire further presses the nut 9. When disassembling, the wound steel wire is cut, the nut 9 is loosened and the screw 4 is pulled out, and the track plate 2 can be separated. When replacing the new track plate, the above splicing and locking steps are repeated.
[0034] By winding steel wire around the annular groove 11 of the fixing column 8 and the annular groove 13 of the screw 4, a mechanical lock is formed, which effectively restricts the relative rotation of the nut 9 and the screw 4. Combined with the tightening and fixing of the nut 9 and the washer 12, the double anti-loosening mechanism significantly enhances the vibration resistance of the connection, avoids the nut from loosening due to high-frequency vibration, and reduces the risk of track plate displacement and fall off.
