Description

Technical Field

[0001] The utility model relates to the technical field of automated intensive warehousing, and particularly relates to a lifting and reversing mechanism for a four-way shuttle vehicle. Background Art

[0002] In recent years, the construction pace of domestic intensive warehouses and modern logistics distribution centers has accelerated, continuously promoting the logistics automation conveying technology. The demand for the supporting four-way shuttle vehicle equipment has been increasing, making it widely used in automated intensive warehousing systems.

[0003] Currently, the reversing mechanisms of four-way shuttle vehicles with mechanical lifting structures generally use screw jacks or cam lifters. For the screw jack type, the ball screw nut seat rotates and then drives the ball screw to move up and down to achieve the lifting and reversing function of the four-way shuttle vehicle; for the cam lifter type, the cam rotates to achieve the lifting and reversing function of the four-way shuttle vehicle. Since the screw jack uses a ball screw, the later maintenance cost is high and the whole set of mechanism needs to be replaced; for the cam lifter type lifting and reversing mechanism, when the cam radius changes, the force arm changes in real time, and the demand for the motor power is relatively high. Summary of the Invention

[0004] Aiming at the above problems existing in the existing four-way shuttle vehicles, the present invention aims to provide a lifting and reversing mechanism for a four-way shuttle vehicle with a simple installation structure, low processing difficulty, low cost and fixed torque output.

[0005] The specific technical solutions are as follows:

[0006] A lifting and reversing mechanism for a four-way shuttle vehicle, comprising:

[0007] A vehicle frame;

[0008] A motor, which is installed on the vehicle frame;

[0009] A gear, which is installed on the output shaft of the motor;

[0010] A sliding plate, which is slidably installed on the vehicle frame in the transverse direction. A rack is arranged horizontally on the sliding plate, and the rack meshes with the gear;

[0011] A lifting frame, which is slidably installed on the vehicle frame in the longitudinal direction. At least one inclined groove is arranged on the lifting frame;

[0012] At least one guiding member, which is connected to the sliding plate and slidably installed in the inclined groove. When the sliding plate moves transversely, the guiding member slides in the inclined groove to lift the lifting frame.

[0013] As a further improvement and optimization of this solution, the guiding member is a cam follower.

[0014] As a further improvement and optimization of this solution, there are two inclined grooves, which are respectively arranged on both sides of the lifting frame, and two corresponding guiding members are provided.

[0015] As a further improvement and optimization of this solution, the vehicle frame has a horizontally arranged guide rail, and the sliding plate is horizontally slidably installed on the guide rail.

[0016] As a further improvement and optimization of this solution, the rack and the sliding plate are detachably connected by screws.

[0017] As a further improvement and optimization of this solution, the motor is a reduction motor.

[0018] As a further improvement and optimization of this solution, the sliding plate is a rectangular plate.

[0019] The positive effects of the above technical solution compared with the prior art are as follows:

[0020] When the utility model works, the motor drives the gear to rotate. Under the meshing cooperation of the gear and the rack, the sliding plate is driven to slide horizontally, and the guiding member slides in the inclined groove, so as to lift the lifting frame. By converting the horizontal movement displacement of the sliding plate into the lifting operation displacement of the lifting frame, the jacking and reversing function of the four-way shuttle car is achieved. It not only has a simple installation structure and low processing difficulty, but also has a low cost and stable torque output. BRIEF DESCRIPTION OF THE DRAWINGS
