Description

Technical Field

[0001] The utility model relates to a novel flap which is convenient for maintenance. Background Art

[0002] The flap is installed in the three-way chute at the head of the belt conveyor to select the material path. The flap has two working positions. When the flap is in the left working position, the material coming in from the top of the three-way chute flows out from the right discharge port. When the flap is in the right working position, the material coming in from the top of the three-way chute flows out from the left discharge port.

[0003] The traditional flap is a closed box beam structure assembled by welding steel plates. The internal space is small and the surface is covered with wear-resistant lining plates, which are fixed by four lining plate screws and nuts welded inside the box beam. When the lining plate is excessively worn and needs to be replaced, the surface of the lining plate screws is also excessively worn and cannot be removed with a screwdriver. The lining plate screws can only be cut off with oxygen acetylene, and then the new lining plate is welded to the surface of the flap.

[0004] The defects of traditional flaps are that the internal space is small and the liner nuts are welded to the inner side of the bending plate. When the liner is excessively worn and needs to be replaced, the liner screws cannot be directly removed because the I-shaped communication on the surface of the liner screws has been worn away. The liner can only be cut into small pieces and separated from the flap, and then the liner screws are cut to be flush with the flap, and then the new liner is welded to the surface of the flap as a whole. When the new liner is worn again, replacement becomes more difficult. Summary of the invention

[0005] The problem to be solved by the utility model is to provide a new type of flap which is convenient for maintenance, thus overcoming the shortcomings of the prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a new type of flap that is easy to maintain, comprising a driving shaft, two bent plates and at least one arc-shaped cover plate, the lower part of the bent plate has a bent portion, the two bent plates are relatively arranged to have a structure with a fan-shaped cross section, the bent plate is fixed to the driving shaft below the bent portion by fixing bolts, the two bent plates are connected by two first ribs fixed on both sides of the bent plates and at least one second rib fixed in the middle of the bent plates, the first rib and the second rib are both frame plates with a fan-shaped cross section, the first rib and the second rib are both fixed on the outward surface of the bent plate, and the arc-shaped cover is fixed to the top of the two bent plates and spans the top of the two bent plates;

[0007] The outer side surface of the bending plate is covered by a plurality of lining plates, and the lining plates are bolted to the outer side surface of the bending plate.

[0008] Optionally, a first positioning plate is provided on the first rib plate in an area spanning between the two bent plates, and a second positioning plate is provided on the second rib plate in an area spanning between the two bent plates, and the arc cover plate is bolted to the first positioning plate and the second positioning plate.

For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood by specific circumstances.

[0026] like Figure 1 , Figure 2 As shown, the utility model provides a new flap for easy maintenance, including a drive shaft 1, two bent plates 5 and at least one arc-shaped cover plate 7, wherein the drive shaft 1 is made of 45# steel, 2880mm long, the middle part is a square structure, the side length is 180mm, and the diameter of 9 through holes is 25mm; Figure 3 , Figure 4As shown, the lower part of the bending plate 5 has a bending portion 5-1, the bending plate material is Q235, the length is 2028mm, the width is 1320mm, the thickness is 12mm, the bending position angle is 167 degrees, the diameter of the hole 5-2 for installing the liner is 19mm, and the diameter of the hole 5-3 for fixing the drive shaft and the shielding strip is 25mm; the number of arc-shaped cover plates 7 can be adjusted according to the size of the top of the flap. In this embodiment, two arc-shaped cover plates 7 are used, and the arc-shaped cover plates are made of Q235. Each arc-shaped cover plate is 25mm. The arc cover plate 7 is 1014 mm long, 10 mm thick, 700 mm long, 1230 mm in radius, 33 degrees in angle, and 8 through holes with inner diameters of 12 mm. The two bent plates 5 are arranged opposite to each other to form a fan-shaped cross-section structure. The bent plate 5 is fixed to the drive shaft 1 below the bent portion 5-1 by a fixing bolt 2-1. The two bent plates 5 are connected by two first ribs 3 fixed on both sides of the bent plates and a second rib 4 fixed in the middle of the bent plate 5. Figures 5 to 8 As shown, the first rib plate 3 and the second rib plate 4 are both frame plates with fan-shaped cross-sections. The first rib plate 3 and the second rib plate 4 are both fixed on the outward surface of the bent plate 5. The first rib plate 3 is made of Q235 material, 12mm thick, 180mm wide at the bottom, 1120mm in radius, and 26 degrees in top arc. Two first positioning plates 3-1 are welded on the top. The first positioning plates are 80mm long, 40mm wide, and the internal thread specification is M10. The second rib plate 4 is made of Q235 material, 12mm thick, 180mm wide at the bottom, 1120mm in radius, and 26 degrees in top arc. Four second positioning plates 4-2 are symmetrically welded on the top. The second positioning plates 4-2 are 80mm long, 40mm wide, and the internal thread specification is M10. The arc cover plate 7 is fixed on the tops of the two bent plates 5 and spans the tops of the two bent plates 5.

[0027] The outer side of the bending plate 5 is covered by 24 lining plates 6, and the lining plates 6 are bolted to the outer side of the bending plate 5. Each lining plate 6 is 330 mm long, 275 mm wide, 16 mm thick, and made of Q345 material.

[0028] A shielding strip 2 is provided on the outer side of the bending plate 5. The shielding strip 2 is located below the bending portion 5-1. The shielding strip 2 is used to prevent the bolts from being washed and worn by materials.

[0029] like Fig. 9 , Fig.10As shown, the shielding strip 2 is formed by splicing the first steel plate 2-2 and the second steel plate 2-3. The first steel plate 2-2 and the second steel plate 2-3 are spliced ​​to form an L-shaped structure in cross section. The second steel plate 2-2 is bolted to the bending plate 5; there is a rib plate 2-4 between the first steel plate 2-2 and the second steel plate 2-3. The first steel plate 2-2 is 2030mm long, 80mm wide, and 10mm thick; the second steel plate 2-3 is 2030mm long, 100mm wide, and 10mm thick; the rib plate 2-4 is a right-angled triangle structure, with two right-angled sides of 100mm and 80mm long, 10mm thick, and 9 through holes with a diameter of 25mm. The first steel plate 2-2, the second steel plate 2-3, and the rib plate 2-4 are all made of Q235.

[0030] like Fig.11 , Fig.12 As shown, the new flap 10 is installed in the three-way chute. Under the action of the driving force, the new flap 10 can rotate around the driving shaft 1. When the new flap 10 rotates to the right working position, the material 8 from the feed port 9 flows out from the first discharge port 11. When the new flap 10 rotates to the left working position, the material from the feed port 9 flows out from the second discharge port 12. Compared with the traditional flap, the new flap 10 has ample internal space and the top width reaches 700mm. When replacing the liner, you only need to loosen the screws to remove the arc cover 7 and cut off the liner screws with oxygen acetylene. At this time, the liner 6 can fall off by itself. After installing the new liner, the liner screws 6-1 can be directly tightened from the inside of the flap.

[0031] The above is a detailed description of the embodiments of the utility model, but the contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
