Description

Technical Field

[0001] The present invention relates to a shuttle vehicle for a three-dimensional warehouse, and particularly to an anti-collision mechanism used on a shuttle vehicle for a three-dimensional warehouse. Background Art

[0002] In an automated three-dimensional warehouse, a shuttle vehicle travels on a track in a lane to complete the transfer of goods; an anti-collision mechanism is provided on the frame of the shuttle vehicle body, which can play a role in reducing the damage caused after being collided when an accidental collision occurs; the existing anti-collision mechanism on the frame of the shuttle vehicle body uses polyurethane or rubber blocks, which are installed at the end of the shuttle vehicle body in the traveling direction. The anti-collision mechanism is divided into two types. One is a polyurethane buffer block, which is arranged at the end of the frame of the shuttle vehicle body directly above the track to buffer the collision force between the shuttle vehicle body and the end of the track and prevent the shuttle vehicle from being damaged by collision; the other is a trigger mechanism, in which a contact sensor is installed. When a collision occurs, the contact sensor emits an electrical signal to make the shuttle vehicle stop running as soon as possible; however, in on-site operation, when a shuttle vehicle hits a person, neither of the above two mechanisms can effectively reduce the collision damage; how to develop a mechanism with a simple structure that can greatly reduce the collision damage has become a technical problem to be solved on-site. Summary of the Invention

[0003] The present invention provides an anti-collision mechanism for a shuttle vehicle of a three-dimensional warehouse, which solves the technical problem that the existing anti-collision mechanism cannot effectively reduce the collision damage.

[0004] The present invention solves the above technical problems through the following technical solutions: An anti-collision mechanism for a shuttle vehicle of a three-dimensional warehouse includes a track arranged in the left-right direction, and a shuttle vehicle is arranged on the track; a first pin shaft is arranged at the left end of the vehicle body frame of the shuttle vehicle, a swing arm is movably hinged on the first pin shaft, a second pin shaft is arranged at the outer end of the swing arm, a swing block is hinged on the second pin shaft, and a rubber buffer block is arranged on the left end face of the swing block as an anti-collision safety edge; a cantilever block is arranged on the left side of the first pin shaft, and a compression spring is connected between the cantilever block and the inner end of the swing arm.

[0005] A trigger switch is arranged between the outer end of the swing arm and the swing block, and the trigger switch is electrically connected to the drive motor of the shuttle vehicle.

[0006] The included angle between the swing arm and the horizontal direction is an acute angle.

[0007] The structure of the present invention is simple and the operation is convenient. The collision force of the shuttle vehicle is flexibly processed, greatly reducing the degree of damage caused by the collision. Brief Description of the Drawings

[0008] Figure 1 It is a schematic structural diagram of the present invention. Detailed implementation mode

[0009] The present invention will be described in detail below with reference to the accompanying drawings: An anti-collision mechanism for a shuttle vehicle in a three-dimensional warehouse includes a track 1 arranged in the left-right direction, and a shuttle vehicle 2 is arranged on the track 1; a first pin shaft 5 is arranged at the left end 3 of the vehicle body frame of the shuttle vehicle 2, a swing arm 6 is movably hinged on the first pin shaft 5, a second pin shaft 7 is arranged at the outer end of the swing arm 6, a swing block 8 is hinged on the second pin shaft 7, and a rubber buffer block 9 is arranged on the left end face of the swing block 8; a cantilever block 12 is arranged on the left side of the first pin shaft 5, and a compression spring 13 is connected between the cantilever block 12 and the inner end of the swing arm 6. The compression spring 13 supports and pads up the swing arm 6, making it tilt upward and protrude to the left; when the shuttle vehicle 2 travels from right to left and touches an obstacle 11, the rubber buffer block 9 first contacts the obstacle 11, causing the swing block 8 to rotate clockwise around the second pin shaft 7, triggering the trigger switch 10, and sending an electrical signal to make the drive motor of the shuttle vehicle 2 enter the braking state. At the same time, under the action of the impact force, the swing arm 6 rotates clockwise around the first pin shaft 5, and the driven swing arm 9 ensures that the swing block 8 is always in the horizontal direction, thereby playing a role in reducing the impact force. During the clockwise rotation of the swing arm 6, the compression spring 13 is stretched; when the obstacle 11 is removed, the swing arm 6 rotates counterclockwise and returns to the initial state.

[0010] A trigger switch 10 is arranged between the outer end of the swing arm 6 and the swing block 8, and the trigger switch 10 is electrically connected to the drive motor of the shuttle vehicle 2; an anti-collision mechanism the same as the swing arm mechanism arranged on the left end of the vehicle body frame is also arranged on the right end 4 of the vehicle body frame of the shuttle vehicle 2 to realize the protection when the shuttle vehicle 2 travels to the right.

[0011] The included angle between the swing arm 6 and the left-right horizontal direction is an acute angle; Figure 1 The working states of the swing arm 6 before and after the collision are indicated.
