After a certain amount of lubricant is added to the lubricant storage chamber 605 through the lubricant addition port, the lubricant storage chamber 605 is pressurized so that the lubricant therein enters the extrusion reflux chamber 606 along the guide channel 607, and a part of the lubricant entering the extrusion reflux chamber 606 enters the discharge hole 608.

[0044] In this embodiment of the present invention, the first roller assembly 32 and the second roller assembly 41 both include a porous roller 321 adapted to the rail, the porous roller 321 is located inside the roller mounting cover 103, and a hollow shaft body 322 connected to its inner cavity is fixedly provided on one side of the porous roller 321 (the cavity interconnected between the porous roller 321 and the hollow shaft body 322 is the purge flow channel), the hollow shaft body 322 on the first roller assembly 32 is rotatably matched inside the corresponding hollow lubrication box 601 (the cavity interconnected between the porous roller 321 and the hollow shaft body 322 is the purge flow channel), and the hollow shaft body 322 on the second roller assembly 41 is rotatably matched inside the corresponding hollow lubrication box 601. 01, when the porous roller 321 rolls forward along the rail, the lubricant in the discharge hole 608 is evenly dispersed to the side surface of the hollow shaft 322 through the rotation of the hollow shaft 322, thereby achieving lubrication treatment between the contact surface of the hollow shaft 322 and the hollow lubrication box 601, and the side surfaces of the hollow shaft 322 on the first roller assembly 32 are respectively provided with a first reciprocating spiral groove 323 and a second reciprocating spiral groove 324, the first reciprocating spiral groove 323 is located on the inner side of the corresponding U-shaped carrier frame 31, and the second reciprocating spiral groove 324 is located on the outer side of the corresponding U-shaped carrier frame 31, and the hollow shaft 322 and the corresponding roller mounting cover 103 are rotated to cooperate with each other.

[0045] In this embodiment of the present invention, the first bearing mechanism 3 also includes a reflux control component 33; wherein the reflux control component 33 includes a first reflux plate 331 that is slidably fitted inside the corresponding extrusion reflux chamber 606, one side of the first reflux plate 331 is connected to a first movable ring 333 located outside the hollow lubrication box 601 through a first fixed rod 332, the first fixed rod 332 and the hollow lubrication box 601 are slidably fitted, an elastic element 334 is provided between the first movable ring 333 and the corresponding hollow lubrication box 601, and the first reflux plate 331 in the initial state is against the corresponding limit ring 602, and the elastic element 334 is in a self-locking state. When the lubricant in the lubricant storage chamber 605 is controlled to enter the extrusion reflux chamber 606 along the guide channel 607, as the lubricant entering the extrusion reflux chamber 606 gradually increases, a thrust is generated on the first reflux plate 331, causing the first reflux plate 331 to move toward the outside of the U-shaped carrier frame 31, thereby causing the lubricant in the lubricant storage chamber 605 to gradually transfer to the extrusion reflux chamber 606. During this process, the elastic element 334 is gradually stretched. When the lubricant in the lubricant storage chamber 605 is completely discharged, the first reflux plate 331 just rests against the inner wall of the extrusion reflux chamber 606 away from the limiting ring 602.

[0046] In this embodiment of the present invention, the first bearing mechanism 3 also includes two lubrication delivery components 34 symmetrically arranged inside the U-shaped bearing frame 31; wherein the lubrication delivery component 34 includes a support frame 341, and the two ends of the support frame 341 are fixedly provided with a second movable ring 342, and the inner wall of the second movable ring 342 corresponding to the first roller assembly 32 is fixed with a guide protrusion 343 that slides in the first reciprocating spiral groove 323 (the reciprocating spiral groove provided on the hollow shaft 322 is similar to the function of the reciprocating screw rod), and the lubricant storage chamber 605 is slidably provided with a The extrusion conveying plate 344 is in an initial state against the corresponding limit ring 602. The extrusion conveying plate 344 and the second movable ring 342 are connected by a second fixed rod 345. The second fixed rod 345 and the corresponding hollow lubrication box 601 are in sliding cooperation. In the process of pushing the trolley forward along the rail, the rolling of the porous roller 321 drives the corresponding hollow shaft 322 to rotate. In the process of the hollow shaft 322 on the first roller assembly 32 rotating, the guide protrusion 343 and the first reciprocating spiral groove are connected. The cooperation relationship between the lubricant conveying assembly 34 and the lubricant conveying assembly 34 is such that the entire lubricant conveying assembly 34 moves toward the center of the U-shaped carrier 31. In this process, the lubricant conveying plate 344 moves away from the limit ring 602 and squeezes the lubricant in the lubricant storage chamber 605. Under the action of the squeezing force, the lubricant enters the extrusion reflux chamber 606 along the guide channel 607, and a part of the lubricant entering the extrusion reflux chamber 606 enters the discharge hole 608 for lubrication of the hollow shaft body 322. As the lubricant entering the extrusion reflux chamber 606 gradually The increase will generate thrust on the first return plate 331, so that the first return plate 331 moves toward the outside of the U-shaped carrier 31, and then the lubricant in the lubricant storage chamber 605 is gradually transferred to the extrusion return chamber 606. In this process, the elastic element 334 is gradually stretched. When the extrusion conveying plate 344 just abuts against the inner wall of the lubricant storage chamber 605 away from the limit ring 602, the lubricant in the lubricant storage chamber 605 is completely discharged, and the first return plate 331 just abuts against the inner wall of the extrusion return chamber 606 away from the limit ring 602;

[0047] As the hollow shaft 322 continues to rotate in the same direction, when the entire lubrication conveying assembly 34 moves away from the center of the U-shaped carrier 31, the first return plate 331 gradually moves towards the direction close to the limit ring 602 under the elastic restoring force of the elastic element 334 until it rests against the corresponding limit ring 602 again. In this process, the lubricant in the extrusion reflux chamber 606 is squeezed by the first return plate 331, so that the lubricant therein flows back to the lubricant storage chamber 605 along the guide port 603, the guide chamber 604 and the guide channel 607 in turn, and the extrusion conveying plate 344 moves away from the center of the U-shaped carrier 31 until it rests against the corresponding limit ring 602 again (i.e., the reset is completed). By repeating the above movement process, continuous lubrication operation can be achieved between the contact surface of the hollow shaft 322 and the hollow lubrication box 601.

[0048] Specific embodiment 2, on the basis of specific embodiment 1, the second bearing mechanism 4 also includes a wind control component 42 symmetrically arranged on both sides of the corresponding U-shaped bearing frame 31; wherein the wind control component 42 includes a second reinforcement plate 422 fixedly arranged between the two U-shaped bearing frames 31, the first reinforcement plate 104 is fixedly installed between the two U-shaped bearing frames 31, the wind control shaft 420 is rotatably arranged on the second reinforcement plate 422, and the end of the wind control shaft 420 away from the wind impeller 421 is fixedly installed with a first pulley 423, and the second roller A second pulley 424 is fixedly mounted on the hollow shaft body 322 of the wheel assembly 41, and the first pulley 423 is connected to the second pulley 424 by a transmission belt 425. Through the joint action of the first pulley 423, the second pulley 424 and the transmission belt 425, the kinetic energy of the second roller assembly 41 during the rolling process can be effectively converted into the rotational kinetic energy of the wind control shaft 420. There is no need to set up a separate power structure for the rotation control of the wind control shaft 420, thereby realizing efficient use of the kinetic energy during the forward movement of the trolley.

[0049] In this embodiment of the present invention, the wind control component 42 also includes a reciprocating frame 426 slidably mounted on the wind control shaft 420, the reciprocating frame 426 is slidably mounted between the two hollow shaft bodies 322, a guide protrusion 343 slidably matched with the second reciprocating spiral groove 324 is fixed in one of the through openings on the reciprocating frame 426, a third fixed rod 427 slidably matched with the corresponding hollow lubrication box 601 is fixed at another through opening on the reciprocating frame 426, a second return plate 428 slidably matched in the extrusion return chamber 606 is fixed at one end of the third fixed rod 427, the second return plate 428 in the initial state is against the corresponding limit ring 602, and in the process of the lubricant entering the extrusion return chamber 606, a thrust is generated on the first return plate 331, so that the first return plate 331 moves toward the outside of the U-shaped carrier frame 31, and in this process, the movement of the first movable ring 333 drives the elastic element 334 to be gradually stretched, The cooperation relationship between the guide protrusion 343 and the second reciprocating spiral groove 324 enables the reciprocating frame 426 to move synchronously with the first moving ring 333 toward the outside of the U-shaped carrier frame 31. When the extrusion conveying plate 344 just abuts against the inner wall of the lubricant storage chamber 605 away from the limit ring 602, the lubricant in the lubricant storage chamber 605 is completely discharged, and the first return plate 331 just abuts against the inner wall of the extrusion return chamber 606 away from the limit ring 602. The flow plate 428 also just rests against the inner wall of the extrusion reflux chamber 606 away from the limit ring 602. In the process of the elastic element 334 retracting to drive the first movable ring 333 to reset, the reciprocating movable frame 426 that is always in contact with the first movable ring 333 and keeps synchronous movement can ensure the squeezing force of the lubricant in the lubricant storage chamber 605 during the resetting process of the first reflux plate 331, so that the lubricant in the extrusion reflux chamber 606 can completely flow back into the lubricant storage chamber 605.
