[0028] The following describes a fork-type mobile robot anti-collision device provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0029] Embodiment 1:

[0030] Combined with Figures 1-4 As shown, a fork-type mobile robot anti-collision device provided by the present utility model includes a freight transport mechanism 100, an anti-collision mechanism 200, and a stretching mechanism 300. The freight transport mechanism 100 includes a power mechanism 110 and a lifting fork 120 connected to the power mechanism 110;

[0031] The anti-collision mechanism 200 includes two plate bodies 210 connected to the lifting fork 120, a motor 220 installed inside the plate body 210, a rotating plate 230 connected to the output shaft of the motor 220, a housing 240 installed outside the rotating plate 230, a rotating shaft 250 movably installed inside the housing 240, a binding strap 260 connected between the two rotating shafts 250, and an anti-collision sensor 270 connected to the binding strap 260. The anti-collision sensor 270 is electrically connected to the power mechanism 110;

[0032] The stretching mechanism 300 includes a cylinder 310 installed outside the rotating plate 230 and a push plate 320 connected to the movable end of the cylinder 310. The push plate 320 is attached to the bent portion of the binding strap 260.

[0033] Furthermore, the two motors 220 are connected in series, and the motor 220 is electrically connected to the power mechanism 110. With this structural design, it is ensured that the two rotating plates 230 can rotate synchronously, so that the binding strap 260 just comes to the outside of the goods, providing conditions for detecting the road conditions.

[0034] Further, an outlet opening suitable for the strap 260 to pass through is formed on the outer shell 240. The width of the outlet opening is greater than the thickness of the strap 260. The size design of the outlet opening enables the strap 260 to flexibly pass through the outer shell 240.

[0035] Embodiment 2:

The arc surface is designed at the bending part of the platform 400. By providing the platform 400, the staff can stand on the platform 400 and move along with the power mechanism 110, improving the comfort of using this device.

[0037] Embodiment 3:

[0038] Combined with Figure 1 、 3 and Figure 4 As shown, in the above embodiment, two annular plates 500 are sleeved on the outer side of the rotating shaft 250. The two annular plates 500 are horizontally symmetrical about the strap 260. By providing the annular plates 500, on the one hand, the strap 260 can be limited, and on the other hand, conditions are provided for installing the torsion spring 600.

[0039] Further, torsion springs 600 are sleeved at both ends of the rotating shaft 250. Both ends of the torsion spring 600 are respectively connected to the inner wall of the outer shell 240 and the rotating shaft 250. Under the action of the torsion spring 600, the rotating shaft 250 can wind up the loosened strap 260.

[0040] The working principle and usage process of the present utility model: When this device is put into actual use, the power mechanism 110 controls the lifting fork 120 to fork and load goods. Then the motor 220 is started, and then the rotating plate 230 drives the outer shell 240, the rotating shaft 250, and the strap 260 to rotate, so that the strap 260 is sleeved on the outer side of the goods. Then the staff can control the extension length of the movable end of the air cylinder 310 according to the length of the goods, so that the push plate 320 stretches the strap 260. After the strap 260 fits on the outer side of the goods, the anti-collision sensor 270 also approaches the goods. Then the power mechanism 110 drives the goods to move, and the anti-collision sensor 270 detects the road conditions at all times to avoid the situation of goods collision.
