The top of the hollow roller 24 is fixedly connected to the conduit 26. A through hole is opened on the inner wall of the conduit 26. The baffles 21 and the inner groove at the right end of the pad 15 are inserted and placed. The inside of the pad 15 and the inside of the baffle 21 are assembled and arranged by external stud threads. Through the above arrangement, an assembly part 2 for combining the right side of the buffer 1 is formed.

[0018] The cooling component 3 includes a connecting frame 31, a sleeve 32, a rubber ring 33, a rubber ring 34, a cover 35 and a silicone ring 36. The sleeve 32 is fixedly arranged on the right end of the connecting frame 31, and the rubber ring 33 and the rubber ring 34 are fixedly arranged inside the sleeve 32. The outer side of the top of the sleeve 32 is threadedly assembled with the inner wall of the cover 35, and a silicone ring 36 is fixedly arranged inside the top of the cover 35.

Through the above arrangement, a cooling component 3 for slidingly placing the conduit 26 is formed.

[0019] The ring plate 13 is located below the baffle 14 , and the buffer spring 16 is spirally arranged on the outside of the column rod 12 . Through the above arrangement, the baffle 14 plays a role in limiting the top of the pad 15 , and the buffer spring 16 plays a role in compressing and buffering the pad 15 and elastically resetting it.

[0020] The front end and rear end of the connecting frame 31 are assembled with the internal threads of the caster bracket plate through external studs, and the front end and rear end of the frame 11 are assembled with the internal threads of the caster bracket plate through external studs. Through the above arrangement, it is convenient to combine and install the buffer part 1, the assembly part 2, the cooling part 3 and the caster bracket.

[0021] Working process: The present invention provides a brake assembly for a heavy-duty caster device, which can provide auxiliary cooling between the caster and the brake component when the brake assembly applies pressure-touch braking to the caster, and the brake assembly is easy to assemble and disassemble.

[0022] The buffer 1, assembly 2 and cooling component 3 provided in the present device are of assembled structure. The buffer 1 and assembly 2 are first combined and limited, and the baffle 21 is inserted into the inner groove at the right end of the pad 15. Then, the inside of the pad 15 and the inside of the baffle 21 are threadedly assembled and limited by external studs. Then, the assembly 2 and the cooling component 3 are combined and limited, and the conduit 26 is slidably inserted and placed between the rubber ring 33 and the rubber ring 34. The connecting frame 31 and the inside of the caster bracket plate are threadedly assembled and limited by external studs. The frame 11 and the inside of the caster bracket plate are threadedly assembled and limited by external studs. Then, the cover 35 is manually reversed to make the cover 35 and the silicone ring 36 detach from the sleeve 32, and cooling cleaning liquid is poured into the sleeve 32. Then, the cover 35 is rotated forward to reset the cover 35 and the silicone ring 36. The silicone ring 36 is made of hard silicone material, and the silicone ring 36 is used to prevent the leakage of cooling cleaning liquid, forming a structure as shown in the figure. Fig. 9 , Fig.10 The sleeve 32 shown is filled with a cooling cleaning liquid distribution position.

[0023] When the caster is braked, the pressure plate 22 is pressed downward, the assembly 2 as a whole and the pad 15 move downward, and the buffer spring 16 is in a compressed state until the flexible roller 23 and the hollow roller 24 contact and fit with the wheel body of the caster, and the guide tube 26 is located as shown in FIG. Fig.12 In the position shown, the cooling cleaning liquid arranged inside the sleeve 32 enters along the through hole of the conduit 26. Since the braking action is short in duration, a small amount of cooling cleaning liquid enters the annular cavity of the hollow roller 24 through the hollow conduit 26. The cooling cleaning liquid enters the annular cavity of the hollow roller 24 to moisten the sponge strip 25. The sponge strip 25 is in close contact with the wheel body of the caster, and the friction heat generating area between the wheel body of the caster and the bottom of the hollow roller 24 is assisted in cooling down, and the wheel body of the caster can be cleaned at the same time. The flexible rollers 23 arranged on both sides of the hollow roller 24 are rollers made of flexible polymer resin material, which have good water absorption. When braking, the wheel body of the caster can be dehumidified to a certain extent. After the braking of the caster is completed, the cushion plate 15 and the assembly part 2 are driven to reset as a whole under the action of the buffer spring 16.
