Description

Technical Field

[0001] The utility model relates to the technical field of AGV trolleys, in particular to a hybrid laser navigation forklift type AGV trolley. Background Art

[0002] Automated guided vehicle, referred to as AGV, is also called automatic guided transporter or automatic guided transporter. An automatic guided vehicle is an industrial vehicle that loads goods automatically or manually, drives automatically along a set route or pulls a cargo trolley to a designated location, and then loads and unloads goods automatically or manually.

[0003] When the existing laser-guided forklift AGV is in use, the goods are placed on the forklift. During transportation, most of the goods lack actual protection on both sides, which makes the stability of the goods decrease when the goods are bumpy or up and down slopes during transportation, posing certain safety hazards. Therefore, we propose to design a hybrid laser-guided forklift AGV. Utility Model Content

[0023] A two-way cylinder 6 is fixedly connected to the center of one side of the vehicle body 1 away from the AGV on-board computer 2, and both telescopic ends of the two-way cylinder 6 are fixedly connected to a lifting frame 7. A first motor 8 is fixedly connected to the top of the lifting frame 7, and a threaded rod 9 is fixedly connected to the driving shaft of the first motor 8. A forklift arm 10 is threadedly connected to the outer wall of the threaded rod 9. A limit frame 5 is fixedly connected to the top of one end of the vehicle body 1 away from the AGV on-board computer 2. A slide groove is provided on the side wall of the vehicle body 1. The top and bottom of the lifting frame 7 are slidably connected to the limit frame 5 and the slide groove respectively. The two-way cylinder 6 is used to drive the two lifting frames 7 to move closer to or away from each other, thereby adjusting the distance between the two forklift arms 10.

[0024] The forklift arm 10 is slidably connected to the inside of the lifting frame 7. The two lifting frames 7 are symmetrically arranged about the two-way cylinder 6. The forklift arm 10 can be stably lifted and lowered in the lifting frames 7. The two lifting frames 7 are symmetrical, and the forklift arms 10 in the lifting frames 7 have the same stroke, which is convenient for jointly lifting and transporting the workpiece.

[0025] A double-axis motor 11 is embedded and fixedly connected inside the vehicle body 1 on one side close to the forklift arm 10. Both driving shafts of the double-axis motor 11 are fixedly connected with a screw rod 12. The screw rod 12 passes through the vehicle body 1 and is threadedly connected to a guard arm 13. Limit rods 14 are fixedly connected to both sides of the outer wall of the vehicle body 1. The limit rods 14 pass through the guard arm 13 and the ends are fixedly connected to limit blocks, which are convenient for limiting the travel of the guard arm 13 to prevent it from falling out.

[0026] The inner wall of the arm guard 13 is provided with a clamping plate 15, and the inner wall of the clamping plate 15 is fixedly connected with a rubber pad 18, which contacts with the cargo to facilitate clamping and protection. A locking bolt 16 is threadedly connected to the middle of the arm guard 13, and the locking bolt 16 penetrates the arm guard 13 and is connected to the bearing of the clamping plate 15. A slideway 17 is provided inside the arm guard 13, and the clamping plate 15 is slidably connected to the slideway 17, so that the position of the clamping plate 15 can be adjusted according to the width of the cargo workpiece, so as to facilitate clamping the cargo or protecting the cargo on the forklift arm 10.

[0027] An infrared ranging probe 19 is fixedly connected to the outer side wall of the end of the guard arm 13 , and an alarm module 20 corresponding to the infrared ranging probe 19 is arranged on the side wall of the vehicle body 1 .

[0028] When in use, the surrounding environment is first scanned by the AGV laser scanner 3, and then the information is transmitted to the AGV on-board computer 2, which autonomously constructs a map and autonomously plans a route.

[0029] Subsequently, the two lifting frames 7 can be driven to move closer to or further away from each other through the bidirectional cylinder 6, thereby adjusting the distance between the two forklift arms 10 to facilitate the lifting and transportation of different goods. After the workpiece is forked up, the dual-axis motor 11 is started to drive the two screw rods 12 to rotate, thereby driving the two guard arms 13 to move closer to each other, thereby facilitating the protection of the outside of the goods.

[0030] When the travel is not enough, the locking bolt 16 can be turned to drive the clamping plate 15 to slide inside the guard arm 13, further reducing the distance between the two clamping plates 15, making it easier to clamp the goods and ensuring the stability of the goods during transportation.

[0031] During the process of adjusting the guard arm 13, the infrared ranging probe 19 is in the on state. When the outer walls of the guard arm 13 are close to external goods or walls, and when the distance is close to the threshold of triggering the alarm module 20, the alarm module 20 will issue an alarm accordingly to prompt the operator and prevent collision with external equipment.

[0032] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
