[0017] The utility model will be further described in combination with the drawings. These drawings are all simplified schematic diagrams, and only schematically show the basic structure of the utility model, so it only shows the components related to the utility model.

[0018] Figure 1 is the structural schematic diagram of the first perspective of the utility model; Figure 2 is the structural schematic diagram of the second perspective of the utility model

[0019] schematic diagram; Figure 3 is the structural schematic diagram of the slide, the axle rod, the connecting frame and the fork arm of the utility model.

[0020] In combination with the drawings Figure 1 and the drawings Figure 3As shown, a forklift circulating hoist includes a cabinet 1, a ring transmission mechanism 2, a slide 3, a shaft 4, a connecting frame 5, a fork 6, rollers 7, track wheels 8, a first bracket 9, a second bracket 10, and a ring track 11. The shaft 4 passes through the through hole of the slide 3 and is rotatably connected to the slide 3. The front section of the shaft 4 is fixed to the connecting frame 5, which is fixed together with the fork 6. The rear section of the shaft 4 is fixed with the first bracket 9 and the second bracket 10, which are perpendicular to each other. Track wheels 8 are rotatably connected to both ends of the first bracket 9 and the second bracket 10. The track wheels 8 cooperate with the ring track 11, which is fixed inside the cabinet 1. Several rollers 7 are rotatably connected to both sides of the slide 3, and several slides 3 are connected to the transmission part of the ring transmission mechanism 2.

[0021] As attached Figure 2 As shown, the ring transmission mechanism 2 includes a drive sprocket 21, a driven sprocket 22, a motor 23, and a chain 24. The drive sprocket 21 and the driven sprocket 22 are rotatably connected to the cabinet 1 via shafts. The drive sprocket 21 and the driven sprocket 22 are both meshed in the inner ring of the chain 24. The slide 3 is fixed on the chain 24, and the output shaft of the motor 23 is fixed on the shaft of the drive sprocket 21.

[0022] The output shaft of motor 23 drives the drive sprocket 21 to rotate, which in turn drives the ring chain 24 to move along the drive sprocket 21 and the driven sprocket 22, thus enabling the slide 3 to move in a ring trajectory.

[0023] The front panel of the cabinet 1 has an annular groove 12 through which the shaft 4 passes. When the slide 3 moves, it will carry the shaft 4 along the annular groove 12. Since the shaft 4 and the slide 3 are rotatably connected, when the slide 3 rotates at an angle while moving along the annular track, it will not cause the shaft 4, the connecting bracket 5 and the fork arm 6 fixed to the shaft 4 to rotate.

[0024] The shaft of the driven sprocket 22 passes through the head ends of the two connecting rods 13, and the tail ends of the two connecting rods 13 are respectively hinged to the left and right sides of the cabinet 1.

[0025] Four rollers 7 are provided on each of the four corners of one side of the slide 3. An annular partition is fixed inside the cabinet 1. Two of the four rollers 7 on one side of the slide 3 are attached to the front end of the annular partition, and the other two rollers 7 are attached to the rear end of the annular partition.

[0026] When the sliding seat 3 moves, the rollers 7 in front of the ring-shaped partition roll on the front end surface of the ring-shaped partition, and the rollers 7 behind the ring-shaped partition roll on the rear end surface of the ring-shaped partition, so that the whole fork arm 6 has better supporting force and stability during movement. Since the mutually perpendicular support 1 9 and support 2 10 are distributed in the form of a cross with the four track wheels 8, the four track wheels 8 can always help the fork arm 6 to keep horizontal during rolling along the ring-shaped track 1 1, so that the fork arm 6 can move along the ring-shaped track while lifting the articles.

[0027] The above is the ideal embodiment according to the present application, and the related personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content of the specification, and must be determined according to the scope of the claims.
