When the winding motor 8 drives the winding column 25 to rotate, the winding column 25 reels or unwinds the steel wire rope 5, thereby adjusting the height of the bucket-shaped screen assembly. When the bucket-shaped screen assembly needs to be inspected and maintained, the bucket-shaped screen assembly is moved to the ground through the steel wire rope 5 to reduce the difficulty of inspection and maintenance; When the steel wire rope 5 suspends the bucket-shaped screen assembly for a long time, in order to increase the service life of the steel wire rope 5 and avoid the steel wire rope 5 from breaking, the steel wire rope 5 needs to be lubricated, thereby ensuring the safety of the bucket-shaped screen assembly during the suspension process. The driving disc 21 is used to drive the swing arm 22 to move while following the synchronous rotation of the winding column 25. The swing arm 22 is used to convert the circular motion of the driving disc 21 into the reciprocating motion of the piston body 23 along the inside of the piston cylinder 11. When the piston body 23 makes a return motion along the inside of the piston cylinder 11, the negative pressure is used to make the piston body 23 absorb the lubricating oil in the lubricating oil tank and introduce it into the inside of the piston cylinder 11. When the piston body 23 makes a forward motion, the piston body 23 is used to inject the lubricating oil into the steel wire rope 5 through the filling assembly, so that the steel wire rope 5 can be lubricated during the process of suspending and lifting the bucket-shaped screen assembly.

[0029] The lubricating oil tank body comprises an oil tank body 12, a one-way valve 17 and an electromagnetic control valve 24, wherein the one-way valve 17 is threadedly connected to the top of the piston cylinder 11, and the electromagnetic control valve 24 is fixedly connected to the one-way valve 17 through a joint, the oil tank body 12 is threadedly connected to the top of the electromagnetic control valve 24, and a filling cover plate is threadedly connected to the top of the oil tank body 12; When the wire rope 5 needs to be lubricated, the electromagnetic control valve 24 is opened, so that when the piston body 23 makes a return motion along the inside of the piston cylinder 11, the negative pressure is used to suck the lubricating oil in the oil tank body 12 into the inside of the piston cylinder 11 through the one-way valve 17. The one-way valve 17 prevents the lubricating oil from flowing back into the oil tank body 12.

[0030] The filling assembly includes an injection pipe 18 and a one-way valve 19, wherein the one-way valve 19 is threadedly connected to the bottom of the piston cylinder 11, and the injection pipe 18 is connected to one end of the one-way valve 19 through a joint, and a flexible bag 14 is bonded to one end of the injection pipe 18 away from the one-way valve 19, and a plurality of pleated holes 16 are opened on one side of the flexible bag 14, and a push plate 13 is welded to one end of the piston rod 20, and the push plate 13 and the flexible bag 14 are fixed by bonding; The propulsion plate 13 and the piston rod 20 are fixedly connected. The piston rod 20 drives the flexible bag 14 to move in the direction close to the steel wire rope 5 during the forward motion. When the flexible bag 14 and the steel wire rope 5 are fitted together, as the flexible bag 14 continues to move, the flexible bag 14 and the steel wire rope 5 are pressed together and deformed, so that the lubricating oil injected into the flexible bag 14 through the injection pipe 18 is squeezed out through the pleated hole 16 and then smeared on the outer wall of the steel wire rope 5. After the deformation, the flexible bag 14 wraps the outer wall of the steel wire rope 5 so that the lubricating oil is evenly smeared on the outer wall of the steel wire rope 5. The one-way valve 19 is used to effectively prevent the lubricating oil in the injection pipe 18 from flowing back when the piston body 23 is making a return motion.

[0031] The support member includes a support seat 1 and a fixing plate 2, the fixing plate 2 is welded to the top of the support seat 1, and an assembly hole is opened on the top of the fixing plate 2; when the support member and the top of the venue are installed, the assembly hole on the fixing plate 2 and the top of the venue are fixed by bolts and other connecting parts.

[0032] A side plate 9 is welded to the outer wall of the top of the support seat 1, and a guide pulley 15 for guiding the steel wire rope 5 is rotatably connected to the outer wall on one side of the side plate 9; the guide pulley 15 is used to guide the steel wire rope 5 during the winding process to ensure the stability of the bucket-shaped screen assembly during the lifting process.

[0033] The bucket-shaped screen assembly includes a supporting steel structure 6 and a frame 4 fixed to the outer wall of the supporting steel structure 6, and the inner wall of the frame 4 is assembled with a screen body 3 by bolts; The supporting steel structure 6 serves as a skeleton to support the frame 4 , and fixes the screen body 3 on the frame 4 , so that images can be displayed from different directions.

[0034] The locking member includes a fixing ring 26 and a U-shaped locking block 30. The fixing ring 26 is fixed to the end of the steel wire rope 5. The U-shaped locking block 30 and the fixing ring 26 are used in cooperation with each other. A cushion block 29 is welded on the top of the supporting steel structure 6, and a clamping seat 31 is welded on the bottom of the U-shaped locking block 30. A threaded column 28 is welded on the bottom of the clamping seat 31. The outer wall of the threaded column 28 is threadedly connected with a nut 27. When connecting, after the U-shaped locking block 30 and the fixing ring 26 are engaged, the threaded column 28 is inserted into the socket opened on the surface of the cushion block 29 so that the socket 31 is pressed against the top of the cushion block 29, and the nut 27 and the threaded column 28 are threadedly connected to complete the fixation between the fixing ring 26 and the U-shaped locking block 30.

[0035] When the present embodiment is in use, the support and the top of the stadium are first fixedly connected, and then one end of the steel wire rope 5 and the bucket-shaped screen assembly are fixed by a locking member, and the winding motor 8 is used to drive the winding column 25 to rotate to reel the steel wire rope 5, so that the bucket-shaped screen assembly is lifted to a certain height, and the screen body 3 is used to display the picture. When the steel wire rope 5 needs to be lubricated, the electromagnetic control valve 24 is opened. When the bucket-shaped screen assembly is in the process of lifting and lowering, the swing arm 22 is used to convert the circular motion of the drive disk 21 into the reciprocating motion of the piston body 23 along the piston cylinder 11. When the piston body 23 makes a return motion, the lubricating oil in the oil tank body 12 is absorbed, and the absorbed lubricating oil enters the piston cylinder 11 through the electromagnetic control valve 24. When the piston body 23 makes a forward motion, the piston body 23 is used to squeeze the lubricating oil in the piston cylinder 11 through the injection pipe 18, and the extruded lubricating oil finally acts on the steel wire rope 5 through the pleated hole 16 on the flexible bag 14, so that the steel wire rope 5 is lubricated during the movement.
