Description

Technical Field

[0001] The utility model relates to a heavy-duty three-coordinate automatic forklift and an automatic loading system, belonging to the field of automated logistics machinery. Background Art

[0002] Stereoscopic warehouse stacker cranes are commonly used in fields such as automated production lines and warehousing logistics. Most of the existing stacker cranes adopt telescopic forks. The forks extend to the bottom of the goods at the picking position to pick up the goods. After the forks with the goods are retracted, they are transferred to the corresponding stacking position for stacking. Although the telescopic forks used in such stacker cranes can save the space required for goods transfer, their load-bearing capacity of the telescopic forks is small and cannot meet more application scenarios; various existing AGV forklifts can be applicable to the picking and transfer of heavy goods, but their movement trajectories are relatively cumbersome and complex, and their working efficiency is not high when used for automatic loading of goods. Content of the Utility Model

[0003] In order to solve the problems of small load-bearing capacity of telescopic forks and low loading efficiency of AGV forklifts in the prior art, the utility model proposes a heavy-duty three-coordinate automatic forklift, which includes a vehicle frame 1. A moving trolley 2 is arranged above the vehicle frame 1. The moving trolley 2 moves back and forth in slideways 3 arranged on the upper ends of the left and right sides of the vehicle frame 1. A gear drive mechanism 21 is arranged at the rear of the moving trolley 2. The gear drive mechanism 21 meshes with a rack 7 horizontally arranged in the front-back direction. The rack 7 is connected to the upper end of the vehicle frame 1. A horizontally arranged and liftable fork 4 is arranged at the front end of the moving trolley 2. Wheels 6 are arranged on the front and rear sides of the lower end of the vehicle frame 1. The wheels 6 roll on a track 5 arranged in the left-right direction.

[0004] The moving trolley 2 further includes a frame body 22. A lifting mechanism 23 is arranged at the front of the frame body 22. The fork 4 is arranged on the lifting mechanism 23.

[0005] One set of wheels 6 is arranged on each of the left and right sides of the rear part of the lower end of the vehicle frame 1, and two sets of wheels 6 are arranged on each of the left and right sides of the front part of the lower end of the vehicle frame 1.

[0006] Track limit blocks 9 are arranged at the lower ends of the four corners of the vehicle frame 1.

[0007] A counterweight block 8 is arranged at the rear of the vehicle frame 1.

[0008] Brushes are arranged on the left and right sides of the wheels 6.

[0009] The utility model also proposes an automatic loading system, which includes a set of the heavy-duty three-coordinate automatic forklifts arranged on each side of the vehicle.

[0010] The working principle of the utility model is:

[0011] A. The wheel 6 drives the frame 1 to drive the mobile trolley 2 to travel along the track 5 to the goods picking position. The lifting mechanism 23 drives the fork 4 to lift upward, so that the fork 4 rises to a height sufficient for picking materials. The gear drive mechanism 21 drives the mobile trolley 2 to move forward, so that the fork 4 picks up the goods. The lifting mechanism 23 drives the fork 4 to continue to lift upward to disengage from the goods conveyor line.

[0012] B. The gear drive mechanism 21 drives the mobile trolley 2 to move backward. The lifting mechanism 23 drives the fork 4 to vertically descend to the initial position. The wheel 6 drives the frame 1 to drive the mobile trolley 2 to travel along the track 5 to the goods loading position. The lifting mechanism 23 drives the fork 4 carrying the goods to lift upward. The gear drive mechanism 21 drives the mobile trolley 2 to move forward. After placing the goods on the vehicle, the mobile trolley 2 returns to the initial position. The wheel 6 drives the frame 1 to drive the mobile trolley 2 back to the goods picking position.

[0013] The beneficial effects of the present utility model are as follows:

[0014] A. By using the mobile trolley 2 to move back and forth on the frame 1, the lifting mechanism 23 and the fork 4 move forward synchronously to pick up and deliver goods. Its structure can increase the load-bearing weight of the fork 4, improve the carrying capacity of the equipment, and solve the problem that the traditional telescopic fork extends forward alone to pick up and deliver goods, and the telescopic structure is easily damaged when the extended fork bears a large load. The frame 1 travels along the track 5 to pick up and deliver goods, and its moving trajectory is simple, shortening the time for picking up and delivering goods and improving the working efficiency of automatic loading of goods.

[0015] B. One such heavy-duty three-coordinate automatic forklift is arranged on each side of the vehicle. The two devices pick up and deliver goods independently, increasing the loading efficiency and improving the production efficiency.

[0016] C. By using two sets of wheels 6 respectively arranged on the left and right at the front of the frame 1, when the mobile trolley 2 moves forward to pick up and deliver goods and the overall center of gravity of the equipment moves forward, the two sets of wheels 6 can increase the contact area with the track 5, increase the bearing pressure of the wheels 6, and improve the reliability of the equipment.

[0017] D. By using a counterweight block 8 provided at the rear of the frame 1, the center of gravity of the equipment can be balanced, ensuring the stability of the mobile trolley 2 when traveling along the track 5.

[0018] E. By using the track limit blocks 9 provided at the lower ends of the four corners of the frame 1, the phenomenon of derailment during traveling along the track 5 can be avoided.

[0019] F. By using brushes provided on the left and right sides of the wheels 6, foreign matters on the track 5 can be cleaned in time during the process of traveling along the track 5. Description of the Drawings
