[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 , in the embodiment of the present utility model, a hoist for forklift workpiece transfer includes a main beam 1. A first limit strip 7 and a second limit strip 8 for restricting the cylindrical member 6 are detachably assembled on the main beam 1. The main beam 1 includes a upper cross beam 11 and a lower cross beam 15 arranged in parallel. A slot hole 16 is provided on the lower cross beam 15. An active pin 2 for restricting the first limit strip 7 from moving in the horizontal direction is arranged in the slot hole 16, and is configured to be able to adjust the position of the active pin 2 in the slot hole 16 in real time according to the number of cylindrical members 6. The main beam 1 further includes reinforcing rib plates 14 respectively connected to the upper cross beam 11 and the lower cross beam 15. First through holes 13 and second through holes 17 are respectively opened at the ends of the upper cross beam 11 and the lower cross beam 15 away from the reinforcing rib plates 14.

[0022] Specifically, the main beam 1 is the main structure of the hoist. Its overall is a hollow steel U-shaped structure. The cross section of the upper cross beam 11 is rectangular, and the cross section of the lower cross beam 15 is composed of a semicircle and a rectangle. There is a reinforcing rib plate 14 at the transition between the upper cross beam 11 and the lower cross beam 15 to strengthen the structure of the weak part. The upper end of the lower cross beam 15 is an arc structure, and its arc surface contacts the inner wall of the hoisted cylindrical member 6, which can avoid excessive stress concentration at the contact position and ensure that the cylindrical member 6 is not easily deformed. The lower end of the lower cross beam 15 is a rectangular structure, and the slot hole 16 penetrates the rectangular structure, facilitating the active pin 2 to pass through the slot hole 16 to complete the restriction of the position of the first limit strip 7. When the cylindrical members 6 between the first limit strip 7 and the second limit strip 8 change, the position of the second limit strip 8 remains unchanged to restrict one side of the cylindrical member 6, while the active pin 2 moves along the slot hole 16 to the other side of the cylindrical member 6, so that the first limit strip 7 can be inserted to limit the other side of the cylindrical member 6, achieving the purpose of clamping multiple cylindrical members 6, thereby realizing no collision during the transfer process, and different numbers of cylindrical members 6 can also be lifted by the hoist.

[0023] Please refer to Figures 2-3 , in one embodiment, preferably, a first fixed pin 4 and a second fixed pin 5 for restricting the second limit strip 8 from moving in the horizontal direction are respectively fixed in the first through hole 13 and the second through hole 17. Further, after the positions of the first fixed pin 4 and the second fixed pin 5 are fixed, the position of the second limit strip 8 can be restricted, so that the second limit strip 8 can only be pulled out in the vertical direction.

[0024] Please refer to Figure 2, in one embodiment, in this embodiment, preferably, the structures of the movable pin shaft 2, the first fixed pin shaft 4, and the second fixed pin shaft 5 are all long cylinders with circular caps assembled at both ends. Further, the long cylinder passes through the slot hole 16, the first through hole 13, or the second through hole 17, and then circular caps are added to both ends of the long cylinder, so that the position of the long cylinder can be fixed to prevent the long cylinder from falling off from the slot hole 16, the first through hole 13, or the second through hole 17.

[0025] Please refer to Figure 2 , in one embodiment, in this embodiment, preferably, lifting lugs 12 are installed on the upper surface of the upper cross beam 11 near both side edges, and hooks 3 are installed on both lifting lugs 12. Further, in order to ensure the stable transfer of the lifting tool, the positions of the two lifting lugs 12 are respectively set at relatively far positions on the upper cross beam 11 and are respectively hooked by the hooks 3 during work, so that the lifting tool can be lifted, facilitating lifting and transportation.

[0026] Please refer to Figure 5 , in one embodiment, in this embodiment, preferably, the first limiting strip 7 includes a U-shaped strip 71 and a handle 72 provided on the surface of the U-shaped strip 71. The inner diameter of the U-shaped strip 71 is adapted to the thickness value of the main beam 1, and a limiting groove 73 adapted to the movable pin shaft 2 is provided on the U-shaped strip 71.

[0027] Specifically, the structure of the first limiting strip 7 is the same as that of the second limiting strip 8. The open end of the U-shaped strip 71 is inserted from top to bottom on the surfaces of the upper cross beam 11 and the lower cross beam 15, so that the position of the U-shaped strip 71 can be preliminarily limited. Secondly, when the end of the movable pin shaft 2 enters the limiting groove 73, the position of the U-shaped strip 71 can be limited again. At this time, the U-shaped strip 71 can clamp a plurality of cylindrical parts 6. Similarly, the second limiting strip 8 can limit the other side wall of the cylindrical part 6, so that the plurality of cylindrical parts 6 between the first limiting strip 7 and the second limiting strip 8 are clamped and fixed, so as to prevent collisions during the transfer process. The existence of the handle 72 facilitates the staff to pull the U-shaped strip 71 away from the main beam 1 from above.

[0028] Please refer to Figure 4 , in one embodiment, in this embodiment, preferably, the slot hole 16 is composed of a long rectangular hole 161 and a plurality of U-shaped holes 162 communicated with it. The inner diameter of the U-shaped hole 162 is adapted to the outer diameter of the movable pin shaft 2.

[0029] Specifically, through the combination of a long rectangular hole 161 and a plurality of U-shaped holes 162, the existence of the long rectangular hole 161 can provide a path for the movement of the movable pin shaft 2 to ensure that the movable pin shaft 2 can move freely. Secondly, the existence of a plurality of U-shaped holes 162 can fix the position of the movable pin shaft 2 to adapt to different combinations of cylindrical parts 6 with different numbers or different sizes.

[0030] Working principle and usage process of the present utility model: After sleeving a plurality of cylindrical members 6 on the lower cross beam 15, insert the second limiting strip 8 and fix one side of the cylindrical member 6 under the action of the first fixing pin shaft 4 and the second fixing pin shaft 5. Secondly, move the movable pin shaft 2 to make the position of the movable pin shaft 2 as close as possible to the side wall of the cylindrical member 6, and then snap it into the corresponding U-shaped hole 162 to fix the position of the movable pin shaft 2. Then insert the first limiting strip 7 to clamp the side of the first limiting strip 7 with the cylindrical member 6, ensuring that a plurality of cylindrical members 6 are tightly connected together and are not prone to shaking during transportation. Finally, hook the lifting hook 3 into the lifting lug 12 for transportation.

[0031] Although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0032] Therefore, the above description is only the preferred embodiment of the present application and is not used to limit the scope of implementation of the present application; that is, all equivalent transformations made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
