Description

Technical Field

[0001] The utility model belongs to the technical field of track positioning, in particular to a track walking positioning mechanism for dock loading. Background Art

[0002] Dock loading is the process of loading the cargo on the dock onto the transport vehicle, and the rail-traveling vehicle is a cargo transfer vehicle that travels back and forth between the dock and the transport vehicle, responsible for transferring the cargo on the dock to the transport vehicle.

[0003] The utility model patent with patent application publication number 202222228164.2 discloses a track walking mechanism. The chassis is composed of two longitudinal beams and several cross beams. One side of the chassis is set as an area for placing the conveying equipment, and the other side is provided with a battery box for counterweight; the chassis is rotatably connected with several axles arranged along the transverse direction through bearings, and running wheels are provided at both ends of the axles; the drive unit includes a motor and a reducer, and the motor drives the axle to rotate through the reducer to achieve walking. Specifically, the chassis is composed of a frame structure composed of longitudinal beams and cross beams, which reduces its own weight and energy consumption while ensuring strength; the battery box is arranged in a balancing manner with the conveying equipment to play a counterweight role to prevent tipping over during work; the wheel rim can clamp the outer walls on both sides of the track to ensure that it is difficult to derail.

[0004] According to the above patents, there is a rail-based positioning mechanism for loading vehicles at docks, but it still has shortcomings in actual use. The most obvious one is that when a rail vehicle is transferring goods, the goods are usually placed directly on the goods. The lack of positioning of the goods can easily cause the goods to shift or fall off during transportation. For this reason, we propose a rail-based positioning mechanism for loading vehicles at docks. Utility Model Content
