Description

Technical Field

[0001] This invention relates to the field of coal transportation equipment, and in particular to a coal transportation device for reducing impact. Background Technology

[0002] Belt conveyors are a common type of transportation equipment used to transport materials along a conveyor belt from one location to another. In thermal power plants, coal is typically transported via belt conveyors. This method of transportation enables automated and continuous conveying, improving efficiency. During transportation, coal is placed on the conveyor belt, which continuously transports the coal from one location to another. The speed and direction of the conveyor belt can be adjusted as needed to control the transportation process.

[0003] However, in actual transportation processes, single belt conveyors often encounter problems such as insufficient length or obstructions along the way. Therefore, multiple belt conveyors are needed to transport goods together. When multiple belt conveyors are working, the connection between them can be problematic. When there is a height difference, coal falling from one belt conveyor onto another can cause impact. This impact increases at higher belt conveyor speeds, affecting the lifespan of the belts and the conveyors beneath them. When rigid plates are used to directly impede the impact of coal, the coal is easily crushed, leading to reduced transmission efficiency and increased dust. Summary of the Invention

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figures 1-11 This is the first embodiment of the present invention. This embodiment provides a coal transportation device for reducing impact, specifically including: a pipeline mechanism 100, which includes a first transportation pipe 101 and a second transportation pipe 102 disposed at the lower part of the first transportation pipe 101; and an energy reduction adjustment mechanism 200, which includes at least three sets of energy reduction components 201 disposed in the first transportation pipe 101 and an adjustment component 202 disposed on the upper part of the energy reduction components 201.

[0035] Furthermore, the first transport pipe 101 includes a first coal collecting section 101a and a conveying section 101b connected to the lower part of the first coal collecting section 101a; the second transport pipe 102 includes a second coal collecting section 102a, which is bolted to the lower part of the conveying section 101b; the conveying section 101b and the first coal collecting section 101a are spaced at a certain angle, the first coal collecting section 101a is perpendicular to the horizontal plane, and the angle between the conveying section 101b and the horizontal plane is less than 70 degrees. This can prevent the belt surfaces of the two belt conveyors with a height difference from overlapping in the horizontal direction, thereby increasing the conveying distance of the belt conveyor.

[0036] Preferably, the energy reduction component 201 includes an energy reduction plate 201a hinged to the side wall of the conveying section 101b, and a shock-reducing component 201b slidably disposed in the energy reduction plate 201a; the adjustment component 202 includes a first adjustment component 202a disposed in the middle of the first conveying pipe 101, and a second adjustment component 202b disposed on the first coal collecting section 101a.

[0037] In this embodiment, the inventors can reduce the impact of coal on the belt below the second transport pipe 102 by using the energy reduction component 201. They can also reduce the impact force of coal on the belt by adjusting the component 202 according to the impact speed, and increase the buffering of coal when the impact force is large.

[0038] Example 2

[0039] Reference Figures 1-12 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the energy reduction plate 201a has a first sliding groove H-1 in the middle and a second sliding groove H-2 on both sides of the first sliding groove H-1; the impact reduction component 201b includes an impact reduction tube 201b-1 slidably disposed in the first sliding groove H-1, a first sliding column 201b-2 fixed on the side wall of the impact reduction tube 201b-1 and slidably disposed in the second sliding groove H-2, and a first spring 201b-3 disposed in the impact reduction tube 201b-1.

[0041] Furthermore, the first adjusting member 202a includes a fixing part 202a-1 fixed on the inner wall of the first coal collecting section 101a, an adjusting column part 202a-2 slidably disposed in the fixing part 202a-1, an adjusting pipe part 202a-3 rotatably disposed in the fixing part 202a-1 and disposed outside the adjusting column part 202a-2, and a pressing pipe part 202a-4 disposed outside the adjusting pipe part 202a-3; the second adjusting member 202b includes a speed measuring member 202b-1 hinged to the inner wall of the first adjusting member 202a, and a support member 202b-2 disposed below the speed measuring member 202b-1, and the pressing pipe part 202a-4 is hinged to the end of the speed measuring member 202b-1.

[0042] Furthermore, the fixing part 202a-1 includes a fixing block 202a-1a fixed on the inner wall of the first coal collection section 101a, a first sliding pipe 202a-1b fixed at the lower part of the fixing block 202a-1a, and a second sliding pipe 202a-1c fixed at the end of the first sliding pipe 202a-1b; a first sliding groove H-3 is provided on the side wall of the first sliding pipe 202a-1b, and the first sliding groove H-3 is a straight groove.

[0043] Furthermore, the adjusting column 202a-2 includes an adjusting column 202a-2a slidably disposed in the first sliding tube 202a-1b, a first sliding column 202a-2b fixed on the side wall of the adjusting column 202a-2a and slidably disposed in the first sliding groove H-3, and a support ring 202a-2c fixed on the side wall of the adjusting column 202a-2a and slidably disposed in the anti-impact tube 201b-1, with one end of the first spring 201b-3 contacting the support ring 202a-2c; a first spiral groove H-4 is provided on the side wall of the adjusting column 202a-2a.

[0044] It should be noted that the adjusting column 202a-2a slides in the first slide groove H-3, which ensures that the adjusting column 202a-2a does not rotate when sliding; under the support of the support ring 202a-2c on the first spring 201b-3, the other end of the first spring 201b-3 can support the shock-reducing tube 201b-1 through elastic force. This allows the energy-reducing plate 201a to transmit the impact force to the shock-reducing tube 201b-1 through the first sliding column 201b-2 under the impact of coal, and reduce the impact force through the first spring 201b-3.

[0045] Furthermore, the regulating tube section 202a-3 includes an regulating tube 202a-3a rotatably disposed in the second slide tube 202a-1c, and a second slide post 202a-3b fixed on the inner wall of the regulating tube 202a-3a, the second slide post 202a-3b being slidably disposed at the top end of the first spiral groove H-4; a second spiral groove H-5 is provided on the outer wall of the regulating tube 202a-3a.

[0046] Furthermore, the pressure tube section 202a-4 includes a pressure tube 202a-4a, a hinged column 202a-4b fixed on the outer wall of the pressure tube 202a-4a, and a third sliding column 202a-4c fixed on the inner wall of the pressure tube 202a-4a. The third sliding column 202a-4c is slidably disposed at the top end of the second spiral groove H-5.

[0047] It should be noted that when the pressure tube 202a-4 slides downward under pressure, the third sliding column 202a-4c will slide from the top of the second spiral groove H-5 to the bottom of the second spiral groove H-5. Since the second spiral groove H-5 is a spiral groove, this will cause the adjusting tube 202a-3a to rotate. The rotating adjusting tube 202a-3a will drive the second sliding column 202a-3b to rotate together, causing the second sliding column 202a-3b to slide from the top of the first spiral groove H-4 to the bottom of the first spiral groove H-4. Since the first spiral groove H-4 is a spiral groove and the spiral direction is opposite to that of the second spiral groove H-5, the adjusting column 202a-2a, which cannot rotate under the limitation of the first sliding groove H-3 and the first sliding column 202a-2b, will be squeezed upward by the second sliding column 202a-3b, and the support ring 202a-2c will also rise together with the adjusting column 202a-2a.

[0048] Preferably, the speed measuring component 202b-1 includes a first speed measuring plate 202b-1a hinged to the inner wall of the first coal collecting section 101a, and a second speed measuring plate 202b-1b slidably disposed outside the first speed measuring plate 202b-1a, with the pressure tube portion 202a-4 hinged to the end of the second speed measuring plate 202b-1b; the support component 202b-2 includes a spring cylinder 202b-2a fixed to the outer wall of the first coal collecting section 101a, a spring column 202b-2b slidably disposed in the spring cylinder 202b-2a with one end extending into the first coal collecting section 101a, and a second spring 202b-2c disposed in the spring cylinder 202b-2a, with the end of the spring column 202b-2b contacting the bottom surface of the second speed measuring plate 202b-1b.

[0049] In this embodiment, after coal falls from the end of a belt conveyor into the first coal collection section 101a, it continues to fall into the conveying section 101b. The gravitational potential energy of the coal and the speed converted by the belt conveyor will be slowed down after impacting the surface of multiple sets of energy reduction plates 201a, so that the speed of the coal falling from the second coal collection section 102a into the next belt conveyor is slowed down, and the next belt conveyor is protected.

[0050] It should be noted that when coal impacts the surface of the energy reduction plate 201a, the impact force of the coal will be transmitted to the first spring 201b-3 through the impact reduction pipe 201b-1. Therefore, the coal is less likely to break when it impacts the surface of the energy reduction plate 201a, and both the coal and the surface of the energy reduction plate 201a can be protected to a certain extent.

[0051] It should be noted that when coal falls into the first coal collection section 101a, it will first impact the surface of the velocity measuring element 202b-1. As the coal velocity increases, due to the increased impact force on the velocity measuring element 202b-1, the spring column 202b-2b supporting the second velocity measuring plate 202b-1b will be pressed deeper into the spring cylinder 202b-2a. This will cause the velocity measuring element 202b-1 to rotate downwards by a certain angle, and the pressure tube part 202a-4 hinged to the end of the second velocity measuring plate 202b-1b will slide down a certain distance. When the pressure tube part 202a-4 slides downwards under pressure, the third sliding column 202a-4c will slide from the top of the second spiral groove H-5 to the second spiral groove H-5. At the bottom; since the second spiral groove H-5 is a spiral groove, this will cause the adjusting tube 202a-3a to rotate. The rotating adjusting tube 202a-3a will drive the second sliding column 202a-3b to rotate together, so that the second sliding column 202a-3b slides from the top of the first spiral groove H-4 to the bottom of the first spiral groove H-4. Since the first spiral groove H-4 is a spiral groove and the spiral direction is opposite to that of the second spiral groove H-5, the adjusting column 202a-2a, which cannot rotate under the limitation of the first sliding groove H-3 and the first sliding column 202a-2b, will be squeezed and raised by the second sliding column 202a-3b. The support ring 202a-2c will also rise together with the adjusting column 202a-2a.

[0052] It should also be noted that after the support ring 202a-2c rises, the energy-reducing plate 201a will rotate upwards by a certain angle under the lifting of the impact-reducing pipe 201b-1. This will make the energy-reducing plate 201a more perpendicular to the inner wall of the conveying section 101b, and the impact angle between the plate surface of the energy-reducing plate 201a and the coal will also be more perpendicular. Therefore, the energy-reducing plate 201a absorbs more impact. Since the adjusting column 202a-2a cannot rotate under the limitation of the inner wall of the first slide pipe 202a-1b, the angle between the axis of the impact-reducing pipe 201b-1 and the energy-reducing plate 201a will increase. This will make the first spring 201b-3 more perpendicular to the energy-reducing plate 201a. Therefore, the impact absorption of the first spring 201b-3 on the energy-reducing plate 201a will also increase.

[0053] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
