[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] As Figures 1-3 shown, the present invention provides a technical solution: an operation compensation structure for a long vehicle steel belt, including a long vehicle conveying body 1. A steel belt supporting roller 11 is rotatably connected between the front and back inner walls of the long vehicle conveying body 1. An operation compensation mechanism 2 is arranged on the long vehicle conveying body 1. An error reduction mechanism 3 is arranged at the bottom of the inner wall of the long vehicle conveying body 1. The operation compensation mechanism 2 includes a side support seat 21. The side support seat 21 is fixedly installed on the front and back of the long vehicle conveying body 1. A synchronous cylinder 22 is fixedly installed on the left side of the side support seat 21. The telescopic end of the synchronous cylinder 22 extends to the right side of the side support seat 21 and is fixedly connected with an extension rod 23. A pressure sensor 24 is fixedly installed at the right end of the extension rod 23. A bearing block 25 is fixedly installed on the right side of the pressure sensor 24. A rotating disk 251 is rotatably connected to the outer wall of the inner side of the bearing block 25. An end support roller 27 is fixedly installed on the side of the rotating disk 251 away from the bearing block 25. A limit collar 271 is fixedly sleeved on the outer wall of the end support roller 27. The pressure sensor 24 is an existing structural model and can be selected as WPL803, etc. The pressure sensor 24 is used to monitor the force exerted by the steel belt on the end support roller 27 to the left. If the steel belt becomes loose, the value of this force will decrease accordingly. The pressure sensor 24 is electrically connected to the synchronous cylinder 22 through an external controller. Thus, the signal of the decreasing pressure value controls the synchronous cylinder 22 to work, which can drive the bearing block 25 to drive the end support roller 27 as a whole to move to the right, making the steel belt fit more tightly on the outer surface of the end support roller 27, realizing the function of automatically performing operation compensation, prolonging the overall service life of the long vehicle conveying body 1, and the limit collar 271 is used to limit the steel belt on the outer surface of the end support roller 27.

[0023] As an implementation manner in this embodiment, as Figure 2 、 Figure 3As shown in the figure, a digital display screen 26 is fixedly installed on the top of the side support seat 21. The digital display screen 26 is used to display the pressure value monitored by the pressure sensor 24. A sliding rod 252 is welded to the left side of the receiving block 25. The outer wall of the sliding rod 252 is slidably connected to the inner wall of the side support seat 21. The pressure sensor 24 is electrically connected to the digital display screen 26 through an external controller. The digital display screen 26 can display the pressure value monitored by the pressure sensor 24, which is convenient for users to observe. During the extension of the synchronous cylinder 22, the sliding rod 252 will slide on the inner wall of the side support seat 21, increasing the stability of the overall movement of the receiving block 25.

[0024] As an implementation manner in this embodiment, as Figure 1 , Figure 4 , Figure 5 shown, the error reduction mechanism 3 includes a hollow plate 31. The hollow plate 31 is fixedly installed at the bottom of the inner wall of the long vehicle conveyor body 1. A net plate 32 is fixedly installed at the top of the inner wall of the hollow plate 31. A connecting flat tube 33 is fixedly connected between two adjacent hollow plates 31. A turning pipe 34 is fixedly connected to the right side of the rightmost hollow plate 31. A blower 35 is fixedly connected to the right side of the turning pipe 34. A gas treatment chamber 36 is fixedly connected to the right side of the blower 35. A guide fin 361 is fixedly installed between the two sides of the inner wall of the gas treatment chamber 36. A semiconductor refrigerator 362 is fixedly installed on the right side of the gas treatment chamber 36. Through holes 363 are formed in the front and back of the gas treatment chamber 36. Non-woven fabric filters 364 are detachably connected to the front and back of the gas treatment chamber 36. Through the design of the connecting flat tube 33, the inner cavities of the three groups of hollow plates 31 are connected. By controlling the operation of the blower 35, external air can be absorbed. At the same time, by controlling the operation of the semiconductor refrigerator 362, the external air can be cooled. The low-temperature air is then ejected from the top of the net plate 32 to cool the steel belt at the outer surface of the upcoming moving end support roller 27, avoiding the problem that the steel belt may have thermal expansion due to high temperature caused by friction and other reasons, which affects the accuracy of pressure monitoring. Through the design of the guide fin 361, the air in the gas treatment chamber 36 can flow tortuously, improving the cooling effect of the cold end of the semiconductor refrigerator 362 on the air. The non-woven fabric filter 364 is connected to the gas treatment chamber 36 by glue, which is convenient for users to disassemble and replace the non-woven fabric filter 364.

[0025] Working principle: During use, the steel belt is made to fit on the outer surface of the end support roller 27 and move along its outer surface. The pressure sensor 24 is used to monitor the force exerted by the steel belt on the end support roller 27 to the left. If the steel belt becomes loose, the value of this force will decrease accordingly. Thus, the signal of the decreasing pressure value controls the operation of the synchronous cylinder 22, which can drive the receiving block 25 to drive the entire end support roller 27 to move to the right, making the steel belt fit more tightly on the outer surface of the end support roller 27. After reaching the preset pressure value, the synchronous cylinder 22 is controlled to stop extending, realizing the function of automatic operation compensation.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
