For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The utility model discloses a hoist hanging tool and a crane, such as Figure 4 As shown, the crane comprises a guide rail 4, a pulley assembly, a hoist 5 and a hoist hanging tool, wherein the hoist hanging tool is used to hang the hoist 5 on the pulley assembly.

[0032] Specifically, Figures 1 to 3The hoist hanging tool comprises a hanging part 1, a bearing 2 and a connecting plate 3. The hanging part 1 comprises a first hanging part 11 having a hanging hole, a second hanging part 12 and a third hanging part 13 which are placed on both sides of the first hanging part 11 and one end of which is not in the same plane as the first hanging part 11, and a hanging rod 14 fixed in the hanging hole. The bearing 2 is fixed on the second hanging part 12. The middle part of the connecting plate 3 can be rotatably fixed on the third hanging part 13, and the two ends of the connecting plate 3 are respectively provided with a first fixing hole 31 and a second fixing hole 32 for fixing the pulley assembly.

[0033] A slide groove is provided on the guide rail 4; the pulley assembly includes a first pulley assembly and two second pulley assemblies, the first pulley assembly includes a first pulley placed in the slide groove and a first connecting portion 61 connected to the first pulley and the bearing 2, the second pulley assembly includes a second pulley placed in the slide groove and a second connecting portion 62 connected to the second pulley and the first fixing hole 31 / second fixing hole 32; the hoist 5 is hoisted on the hoisting rod 14 by a hoisting rope.

[0034] The hoist hanging tool is adopted to realize hoist hanging, and the pulley cooperates with the guide rail to realize the hoisting of the hoist 5 and the hoist hanging tool. The pulley and the guide rail are in line contact, which greatly reduces the friction resistance during pulling, greatly reduces the push and pull force, and reduces the intensity of manual work.

[0035] By adopting the hoist hanging tool, the first pulley assembly is connected to the hanging member 1 through a bearing, and the hanging member 1 and the connecting plate 3 are rotatably connected, thereby ensuring the freedom of movement of the hanging member 1 and improving the manual operability of the hoist.

[0036] Furthermore, in order to further improve manual operability, the bearing 2 is preferably a self-lubricating radial spherical plain bearing.

[0037] In order to facilitate the installation and replacement of the suspension rod, the suspension rod 14 is a bolt. The suspension rod adopts a bolt, and a hole is processed on the side wall of the suspension hole, and a nut is used to realize detachable installation and fixation. In addition, the suspension rod is easy to replace during use. In order to improve stability, a cotter pin can be set at the end of the bolt.

[0038] In order to improve the force balance of the hoist hanging tooling, such as Figure 1 As shown, the first fixing hole 31 is placed between the second fixing hole 32 and the bearing 2; the axes of the first fixing hole 31, the second fixing hole 32 and the bearing 2 are parallel and located on the same plane, and the distance between the axis of the first fixing hole 31 and the axis of the bearing 2 is equal to the distance between the axis of the first fixing hole 31 and the axis of the second fixing hole 32. The axis of the suspension rod 14 and the axis of the first fixing hole 31 are in the same plane, and the plane is perpendicular to the plane where the axes of the first fixing hole 31, the second fixing hole 32 and the bearing 2 are located.

[0039] By adopting the above structure, multi-point contact between the guide rail and the pulley assembly is achieved, while the force on a single pulley is dispersed, thereby improving stability; and during hoisting, it can be ensured that each pulley is evenly stressed, further improving stability.

[0040] In order to improve the structural stability, Figure 2 As shown, the connecting plate 3 has two pieces, which are respectively fixed on both sides of the third lifting part 13.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
