Technical Field

[0001] The present application relates to the technical field of slag discharge of tunnel boring machines, and in particular to a special cleaner for slag discharge belts. Background Art

[0002] At present, tunnel construction is generally completed by tunnel boring machines. A typical tunnel boring machine includes a main machine, a slag discharge system and a supporting system. Among them, the slag discharge system is used to discharge the broken slag, and the slag discharge method commonly used in the slag discharge system is continuous belt conveyor slag discharge.

[0003] During the research and improvement, the R&D personnel found that there were some small stones in the debris. The belt would be mixed with small stones and enter the belt rolling wheel, which could easily cause damage to the belt, resulting in the defect that the belt is easily damaged.

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a special cleaner for a slag discharge belt.

[0034] Reference Figure 1 A special cleaner for a slag discharge belt comprises a belt 1, a supporting frame 3 and a cleaning component 2. The supporting frame 3 supports the belt 1 and the cleaning component 2. The belt 1 is used for slag discharge, and the cleaning component 2 is used for cleaning small stones on the belt 1.

[0035] Reference Figure 1The supporting frame 3 is placed on the ground, and the supporting frame 3 is rectangular. One end of the supporting frame 3 in the length direction is higher and the other end is lower. The belt 1 is installed on the supporting frame 3. The length direction of the belt 1 is the same as the length direction of the supporting frame 3. The belt 1 also has one end higher and the other end lower. The transmission direction of the belt 1 is from high to low.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The cleaning component 2 includes a U-shaped frame 21 and a cleaning plate 22. Sliders 6 are fixed at both ends of the U-shaped frame 21. The length direction of the sliders 6 is the same as the length direction of the two sides corresponding to the U-shaped frame 21. The same slide grooves 7 are opened on both sides of the length direction of the supporting frame 3. The length direction of the slide groove 7 is the same as the length direction of the U-shaped frame 21. The slides 6 are embedded in the slide grooves 7. The slides 6 slide in the slide grooves 7, and one slide 6 corresponds to one slide groove 7. The U-shaped frame 21 is perpendicular to the supporting frame 3. The cleaning plate 22 is fixed on the long side of the U-shaped frame 21. The cleaning plate 22 and the U-shaped frame 21 are in the same plane, and the cleaning plate 22 is always in contact with the belt 1. The cleaning plate 22 is perpendicular to the belt 1, and the cleaning plate 22 is a cleaning plate 22 made of rubber material.

[0037] Two electric push rods 5 are fixed at the lower end of the load-bearing frame 3. The two electric push rods 5 are respectively placed on the two sides of the length direction of the load-bearing frame 3. The length direction of the electric push rod 5 is the same as the length direction of the load-bearing frame 3. The piston rod of the electric push rod 5 faces the higher end of the load-bearing frame 3. One end of the piston rod of the electric push rod 5 is fixedly connected to the U-shaped frame 21. A storage bin 4 is fixed at the higher end of the load-bearing frame 3. The bin opening of the storage bin 4 is aligned with the starting section of the belt 1, and the storage bin 4 is arranged in the vertical direction. When the electric push rod 5 is the longest, the cleaning plate 22 It is located directly above the storage bin 4. When the belt 1 is discharging slag, the belt 1 is started, and the electric push rod 5 is not started. The cleaning plate 22 is fixed, and the cleaning plate 22 is in contact with the belt 1. Small stones in the slag will be blocked by the cleaning plate 22, thereby completing the cleaning of small stones in the slag. When there are many accumulated small stones, start the electric push rod 5, and the electric push rod 5 will push the U-shaped frame 21 to make the cleaning plate 22 slide. When it slides to the top of the storage bin 4, the small stones will fall into the storage bin 4, completing the cleaning of the small stones, thereby achieving the effect of protecting the belt 1.

[0038] Reference Figure 1 A sponge layer 8 is fixed to the inner wall of the storage bin 4 , and the sponge layer 8 completely covers the inner wall of the storage bin 4 . When small stones fall into the storage bin 4 , they will come into contact with the sponge instead of directly contacting the storage bin 4 , thereby achieving the effect of protecting the storage bin 4 .

[0039] Reference Figure 1The main body of the electric push rod 5 is provided with a protective shell 9, which is rectangular in shape and completely covers the main body of the electric push rod 5. The protective shell 9 is fixedly connected to the supporting frame 3, and the piston rod of the electric push rod 5 is slidably connected to the protective shell 9. The sliding direction is set along the length direction of the piston rod. The setting of the protective shell 9 prevents small stones from damaging the main body of the electric push rod 5, thereby achieving the effect of protecting the electric push rod 5.

[0040] The implementation principle of a special cleaner for a slag discharge belt 1 in an embodiment of the present application is as follows: when the belt 1 is discharging slag, the electric push rod 5 is started, so that the cleaning plate 22 is placed at the end of the supporting frame 3 away from the electric push rod 5, the electric push rod 5 is fixed, the belt 1 operates normally, and the cleaning plate 22 blocks small stones. When there are many small stones blocked by the cleaning plate 22, the electric push rod 5 is started, and the electric push rod 5 pushes the cleaning plate 22 in a direction away from the electric push rod 5, and the small stones fall into the storage bin 4, thereby completing the cleaning of the small stones.

[0041] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
