[0021] The bottom of the assembly box 4 is fixedly connected with an upper sleeve 6, and the inner wall of the upper sleeve 6 is slidably connected with a lower sleeve 7. The hanging mechanism includes a hanging plate 9, and the lifting rope 8 passes through the interior of the upper sleeve 6 and the lower sleeve 7 in turn and is fixedly connected to the top of the hanging plate 9; by setting the upper sleeve 6 and the lower sleeve 7, the lifting rope 8 extending out of the assembly box 4 is guided and limited for a distance, reducing the swing of the lifting rope 8 during the movement process and improving the transportation stability; the bottom of the hanging plate 9 is fixedly installed with a main hanging hook 13, and the hanging Both sides of the top of the connecting plate 9 are rotatably connected with side support frames 10, and the middle parts of the two side support frames 10 are fixedly installed with support rods 11, and the middle parts of the two support rods 11 are rotatably connected with load-bearing rings, and the middle parts of the two load-bearing rings are fixedly installed with hanging ropes, and the bottoms of the two hanging ropes are fixedly installed with auxiliary hanging hooks 12; by setting the side support frames 10 and the auxiliary hanging hooks 12, when lifting and conveying large objects, the objects can be hung and fixed at multiple positions, thereby improving the stability of the object conveying process.

[0022] A docking arc plate 14 is fixedly installed on the top of the two side support frames 10, and a clamping plate 15 is fixedly installed on one side of the two docking arc plates 14. A clamping block is fixedly installed on one side of one of the clamping plates 15, and a clamping groove is opened on one side of the other clamping plate 15. The two clamping plates 15 can be clamped with each other through the clamping block and the clamping groove. After the two clamping plates 15 are clamped, the two docking arc plates 14 are mutually enclosed to form a ring, and the inner diameter of the ring is slightly larger than the outer diameter of the lower sleeve 7; through the mutual clamping and enclosure of the two side support frames 10, and the upper sleeve 6 and the lower sleeve 7 are arranged in coordination, the side support frames 10 after clamping are limited, thereby hindering the shaking of the hanging plate 9, and reducing the swinging and shaking of the items during transportation.

[0023] Distance sensors are fixedly installed at both ends of the assembly box 4, and a brake mechanism is fixedly installed at the bottom of the inner wall of the assembly box 4. The brake mechanism includes a brake push plate 18, and a docking plate 17 is fixedly installed at the bottom of the brake push plate 18. The bottom of the docking plate 17 is fixedly connected to the inner wall of the assembly box 4 through a pulling spring 20. A docking port is opened in the middle of the docking plate 17. In a natural state, the pulling spring 20 pulls the docking plate 17 and the brake push plate 18, so that a gap is left between the top surface of the brake push plate 18 and the lifting slide rail 2, and the height of the gap is less than the height difference between the reducer and the top surface of the adjusting rod 19;

[0024] An electric push rod 16 is provided on one side of the docking plate 17, and an adjusting rod 19 is fixedly installed on the output end of the electric push rod 16. A reducing tube is fixedly installed on one end of the adjusting rod 19, and the diameter of the reducing tube gradually decreases in the direction away from the electric push rod 16. An extension rod is fixedly installed on the end of the reducing rod away from the reducing tube. Under normal operating conditions, the extension rod is inside the docking port, so that the adjusting rod 19 and the reducing tube can stably penetrate into the docking port when braking.

[0025] A lubrication mechanism is fixedly installed on the top of the inner wall of the assembly box 4, and the lubrication mechanism includes a lubrication box 21. An oil filling port is provided on the top of one side of the lubrication box 21, and lubrication oil is added into the lubrication box 21 through the oil filling port; an oil guide pipe 22 is fixedly installed on the bottom of the lubrication box 21, and an oil guide roller 23 is rotatably installed on the bottom of the oil guide pipe 22. The outer wall of the oil guide roller 23 is provided with a plurality of oil permeable ports. The oil guide roller 23 rolls against the lifting slide rail 2, so that a plurality of protruding oil guide gaskets 24 are squeezed, so that the lubrication oil is discharged from the oil outlet hole, and the lubrication oil is applied to the lifting guide rail, thereby reducing the running resistance between the traveling crane and the lifting slide rail 2 and extending the working life of the device;

[0026] The inner walls of several oil-permeable ports are fixedly mounted with oil guide gaskets 24, which are protruded toward the outside of the oil guide roller 23. Due to the protruding setting of the oil guide gasket 24 and the oil outlet holes in the middle of the oil guide gasket 24, the oil guide gasket 24 can be squeezed during the rolling process of the oil guide roller 23, which is convenient for the real-time discharge of the lubricating oil. After the oil guide gasket 24 is out of contact with the lifting guide rail, it is reset under the action of its own elasticity. Due to the protruding setting of the oil guide gasket 24, it will generate a certain suction force during the frequent squeezing and resetting process, thereby facilitating the movement of the lubricating oil in the lubrication box 21 and the oil guide pipe 22 into the oil guide roller 23.

[0027] When the present invention is in use, the article to be transported is docked with the main hook 13 through the cables and other components, and the electric hoist 5 is started to wind the lifting rope 8, drive the hook plate 9 and the main hook 13 to rise, and then lift the article, and then the assembly box 4 driven by the crane moves along the lifting slide rail 2 to realize the transfer and transportation of the article. During the transportation of the article, a distance sensor detects the distance between the article and the obstacles at both ends of the beam frame 1 in real time. When the article moves to a position close to the end of the beam frame 1 or an obstacle, the electric push rod 16 drives the adjustment rod 19 to move, so that the reducer and the adjustment rod 19 penetrate into the docking interface, drive the docking plate 17 and the brake push plate 18 to lift, so that the top surface of the brake push plate 18 is in contact with the lifting slide rail 2, brake and limit the assembly box 4, and then limit the article to avoid collision with the beam frame 1 or other obstacles.

[0028] When the transported items are large in size, the side support frames 10 on both sides can be flipped and unfolded, and the two auxiliary hooks 12 can be used to assist in hanging and fixing the items, so as to improve the stability of the items during transportation;

[0029] When it is necessary to reduce the shaking during the transportation of items, the upper sleeve 6 and the lower sleeve 7 can be pulled down, and then the two side support frames 10 can be turned over and brought closer, so that the two clamping plates 15 are clamped with each other, and the two docking arc plates 14 surround the ring to form a contact and push with the two sides of the lower sleeve 7. Through the cooperation of the lower sleeve 7 and the upper sleeve 6, the flipping and deviation of the side support frames 10 on both sides are limited, thereby preventing the hanging plate 9 from tilting and shaking, and reducing the probability of shaking of items;

[0030] During the movement and use of the assembly box 4, the lubricating oil in the lubrication box 21 enters the oil guide roller 23 along the oil guide pipe 22, and the oil guide roller 23 rolls against the lifting slide rail 2. Several protruding oil guide gaskets 24 thereon are squeezed, so that the lubricating oil is discharged from the oil outlet hole and coated on the lifting guide rail, thereby reducing the running resistance between the crane and the lifting slide rail 2 and extending the working life of the device.
