Description

Technical Field

[0001] The utility model relates to the technical field of unmanned vehicle equipment, and particularly relates to a sliding mechanism for an unmanned vehicle. Background Art

[0002] As the name implies, a rail-type working vehicle is a transport vehicle that uses rails for directional operation and is usually suitable for transporting various materials.

[0003] The walking device of a rail-type unmanned vehicle disclosed in the publication number CN218808487U can achieve a good limiting effect, avoid the roller bumping and disengaging from the rail, and the roller can rotate and travel on the rail to complete the material transportation, which is stable and efficient. However, during the turning process of the device on the rail, there will be a certain roll when the wheels fit the rail to turn, which is likely to cause rollover. For this reason, we propose a sliding mechanism for an unmanned vehicle. Summary of the Utility Model

[0004] Aiming at the problems in the prior art, the utility model provides a sliding mechanism for an unmanned vehicle.

[0005] The technical solution adopted by the utility model to solve its technical problems is a sliding mechanism for an unmanned vehicle, which includes a load-carrying tray. Four corners of the bottom end of the load-carrying tray are respectively fixedly connected with fixed brackets. Both sides of the bottom end of the fixed brackets are respectively fixedly connected with extension brackets. One end of the extension bracket far away from the fixed bracket is slidably connected with an electric telescopic rod. One side of the electric telescopic rod far away from the extension bracket is rotatably connected with a tension wheel.

[0006] A sliding groove is opened on one side of the extension bracket. The top end and the bottom end of the inner part of the sliding groove are respectively fixedly connected with fixed seats. Buffer springs are installed on the opposite surfaces of the two fixed seats. One end of each of the two buffer springs far away from the fixed seat is respectively installed inside a connecting seat, and the connecting seat is fixedly connected with the top end and the bottom end of a limit slider. A side wall of the limit slider is fixedly connected with an extension rod for connecting the electric telescopic rod.

[0007] By adopting the above technical solution, first place the track wheels on the track, then control the electric telescopic rod to extend, push the tension wheel to extend to the bottom of the track, then place the goods on the surface of the load-carrying pallet and fix them. Then start the electric drive to drive the track wheels to rotate on the track through the transmission connecting rod. When at a moving bend, the tension wheel abuts against the track, and then the limit slider connected to the other end extension rod of the electric telescopic rod slides in the sliding groove opened on the side wall of the extension bracket. The extension bracket is fixed to the four corners of the bottom end of the load-carrying pallet through the fixed bracket. When the limit slider is sliding, the buffer spring connected by the connecting seat contracts to buffer and cooperate with the sliding of the limit slider to achieve slight deflection. The buffer spring is fixed inside the sliding groove through the fixed seat, and the other side slides in the opposite direction. The overall load-carrying pallet is slightly tilted to complete the turning drive, and the track wheels and tension wheels prevent the load-carrying pallet from tipping over.

[0008] Specifically, the center of the fixed bracket is penetrated and rotatably connected with a transmission connecting rod, and the track wheels are respectively installed at both ends of the transmission connecting rod passing through the fixed bracket.

[0009] By adopting the above technical solution, the transmission connecting rod drives the track wheels to rotate for movement.

[0010] Specifically, a layer of buffer pad is fixed on the outer periphery of the tension wheel.

[0011] By adopting the above technical solution, the buffer pad reduces the impact force generated by buffering.

[0012] Specifically, limiting members for limiting sliding are fixedly connected to both sides of the limit slider, and limiting grooves matching the limiting members are opened inside the sliding groove.

[0013] By adopting the above technical solution, the movement range of the limit slider is restricted by the limiting members on both sides of the limit slider and the limiting grooves opened on the inner wall of the sliding groove.

[0014] Specifically, an electric drive is installed at the center of the transmission connecting rod.

[0015] By adopting the above technical solution, the electric drive drives the transmission connecting rod to drive the track wheels to rotate so as to move on the track.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The technical solution of this application is designed with a fixed bracket, an extension bracket, an electric telescopic rod, a tension wheel, a sliding groove, a fixed seat, a buffer spring, a connecting seat, a limit slider and an extension rod to form a roller connection structure for upper and lower clamping. When moving to a bend, the tension wheels on both sides can slide in opposite directions respectively to form a slightly tilted state to cooperate with the bend turning. Then, it returns to the normal position to avoid the situation that the overall equipment derails and rolls over during the bend turning, improving the safety of the overall equipment during use and reducing the occurrence of the unmanned vehicle getting out of the track.
