AI Technical Summary
When lifting bulk cargo, flexible suspenders or wire ropes cause the cargo to swing in the air, creating lateral forces, increasing the bending moment of the hook, resulting in the risk of fatigue and fracture.
A hook cross beam with full angle swing is designed. By setting a link frame between the cross beam and the hook, and setting hinges on the upper and lower parts of the link frame, the full angle swing of the hook is achieved and the lateral force is reduced.
Through the full angle swing of the hook, the lateral force of the cargo swing on the hook is reduced, so as to avoid the hook breakage due to excessive bending moment, and reduce the risk of falling objects in the air.

DETAILED DESCRIPTION
[0029] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form.
[0030] Combination Figure 1 to Figure 6 As shown, a full-angle swinging hook beam of the utility model comprises a beam 1, a connecting frame 2 and a hook assembly 3. By adding a connecting frame 2 between the beam 1 and the hook 303, the full-angle swing of the hook 303 is achieved.
[0031] Combination Figure 1 , Figure 2 As shown, the main function of the crossbeam 1 is to bear the load. The crossbeam 1 is connected to the upper frame of the sling, and an intermediate shaft hole 102 connected to the connecting frame 2 is provided on the crossbeam 1. Figure 2 As shown, the crossbeam 1 is connected to the upper frame of the lifting device through four rotation pin holes 101 set thereon, thereby completing the lifting action; the intermediate shaft hole 102 can be connected to the connecting frame 2 through the upper hinge shaft 401, thereby achieving left and right swing.
[0032] Combination Figure 1 , Figure 3 As shown, the main function of the connecting frame 2 is to connect the crossbeam 1 and the hook assembly 3, and to realize the swing in four directions: front, back, left, and right. The upper part of the connecting frame 2 is connected to the crossbeam 1 at an upper hinge point 201, and the lower part is provided with a lower hinge point 202 connected to the hook assembly 3. The hinge axis of the upper hinge point 201 and the lower hinge point 202 are arranged at 90 degrees. The hook 303 can swing in four directions: front, back, left, and right. Figure 3 , Figure 6As shown, the upper hinge point 201 of the connecting frame 2 is connected to the middle shaft hole 102 on the beam 1 through the upper hinge point shaft 401; the upper hinge point 201 can be set to achieve left and right swing; the lower hinge point 202 is connected to the beam 1 of the hook assembly 3, and the lower hinge point 202 can be set to achieve forward and backward swing. A baffle 203 for fixing the suspension beam 302 is provided above the lower hinge point 202 of the connecting frame 2 to prevent the hook assembly 3 from moving upward.
[0033] Combination Figure 4 , Figure 5 As shown, the hook assembly 3 includes a hook 303, a nut 301 and a suspension beam 302; the hook 303 is fixedly connected to the nut 301; a bearing 304 is provided in the stepped hole at the lower part of the nut 301; the inner ring of the bearing 304 is sleeved on the hook 303, and the lower plane of the bearing 304 falls on the suspension beam 302; the outer part of the suspension beam 302 is fixedly connected to the lower hinge point 202 of the connecting frame 2, and the inner part of the suspension beam 302 is rotatably connected to the hook 303; the hook 303 can realize 360° central rotation through the bearing 304. Figure 4 , Figure 5 As shown, a trapezoidal threaded hole for mounting the hook handle of the hook 303 is provided inside the nut 301, a pressing plate 306 for fixing the hook handle of the hook 303 is provided above the nut 301, a groove for mounting the pressing plate 306 is provided above the nut 301, and a stepped hole for mounting the bearing 304 is provided at the bottom of the nut 301; the hook 303 is connected to the nut 301 through a trapezoidal thread, and is fixedly connected to the nut 301 through the pressing plate 306, and the bearing 304 is installed in the stepped hole at the bottom of the nut 301. A suspension shaft 305 connected to the lower hinge point 202 of the connecting frame 2 is provided on the suspension beam 302, and a suspension hole for the hook handle of the hook 303 to pass through is provided inside the suspension beam 302; the hook 303 passes through the inner ring of the bearing 304 and the suspension hole on the suspension beam 302, and gravity is used to seat the lower plane of the bearing 304 on the stepped surface at the top of the suspension beam 302, so that the hook 303 can achieve 360° central rotation through the bearing 304. The nut 301 is fixed to the hook 303 via a pressing plate 306, so that when the hook 303 rotates, the nut 301 also rotates. The bearing 304 used above is a thrust ball bearing.
[0034] Combination Figure 7 As shown, the working principle of the full-angle swinging hook beam of the utility model is: when the hook beam lifts the goods and moves the goods in the air, the goods will swing accordingly. At this time, due to the action of the upper hinge point 201 and the lower hinge point 202 of the connecting frame 2, the constraints in the four directions of front, back, left and right are released, so that the goods can swing freely in a combination of different angles in any two directions; no matter which direction the goods swing, the hook 303 can swing with it, thereby realizing the full-angle swing of the hook 303, and at the same time, the bearing in the hook assembly 3 can make the goods turn and rotate 360 degrees.
[0035] Combination Figure 7 As shown, the weakest part of the hook beam is the hook 303. The full-angle swing of the hook 303 allows the cargo to swing freely in the air, and the hook 303 also swings along with the cargo, thereby reducing the lateral force on the hook 303 caused by the swinging of the cargo, avoiding the hook 303 from breaking due to excessive bending moment, and preventing the occurrence of aerial falling accidents.
