Description

Technical Field

[0001] This invention relates to the field of metal long product processing equipment, specifically a buffer noise reduction collection basket. Background Technology

[0002] In the long product collection area of ​​the steel pipe production workshop, such as round bars or steel pipes, noise is one of the main sources of pollution in the workshop. When the steel pipes roll down from the inclined grate bars into the material basket, the collision between the steel pipes and the basket frame, and between the steel pipes themselves, generates a lot of noise, especially the collision between hollow thin-walled steel pipes.

[0003] Definitions:

[0004] Noise is a type of sound that causes annoyance or is too loud and harmful to human health. From an environmental protection perspective, any sound that interferes with people's normal rest, study, and work, or that interferes with the sounds people want to hear, is considered noise. From a physics perspective, noise is the sound produced when a sound-producing body vibrates irregularly. When round bars or steel pipes roll down the grate and fall into the basket, they generate a lot of noise due to the collision, especially the collision between hollow steel pipes.

[0005] Noise reduction: As the name suggests, it is about reducing the impact of noise on people. Common methods include: 1. Soundproof rooms; 2. Installing silencers; 3. Sound barriers; 4. Vibration reduction, etc.

[0006] Buffering: This means reducing the impact force, thereby reducing the intensity of the noise emitted.

[0007] Material collection basket: A frame or basket-shaped container used to collect materials. For long materials, a frame structure is generally used. Summary of the Invention

[0008] To reduce the noise generated when long metal materials enter the material basket, this invention provides a buffer noise reduction material basket. This buffer noise reduction material basket is stable, reliable, and easy to operate. It can not only effectively alleviate the noise from the collision between the steel pipe and the basket frame, but also effectively suppress the noise generated by the collision between steel pipes. In particular, it can significantly reduce the noise generated by the collision between hollow thin-walled steel pipes.

[0009] The technical solution adopted by the present invention to solve its technical problem is: a buffer noise reduction collection basket, including a buffer chain shaft, a first power output mechanism and multiple collection units. The multiple collection units are arranged at intervals along the axial direction of the buffer chain shaft. Each collection unit includes a basket frame, a pull wheel and a buffer chain. The basket frame includes a left column and a right column arranged at intervals. One end of the buffer chain is connected to the right column, and the other end of the buffer chain is connected to the pull wheel. The working section of the buffer chain is located between the left column and the right column. The working section of the buffer chain can support long metal materials. The buffer chain shaft passes through the pull wheel of each collection unit. The first power output mechanism can drive the pull wheel to rotate through the buffer chain shaft. When the pull wheel rotates, it can retract and extend the buffer chain.

[0010] The buffer chain shaft is horizontal, with its axis set along the front-to-back direction. The buffer chain shaft is located on the left side of the left column and is connected to the frame via a bearing seat. One end of the buffer chain is connected to the upper part of the right column.

[0011] An idler wheel is located above the traction wheel. Both the idler wheel and the traction wheel are located on the left side of the basket frame. The axis of the idler wheel is parallel to the axis of the traction wheel. The idler wheel is connected to the left column through the first connecting seat assembly, and the buffer chain rests on the idler wheel.

[0012] The first connecting seat assembly includes a hollow shaft, a front steel sleeve, and a rear steel sleeve. The front steel sleeve, idler wheel, and rear steel sleeve are all fitted over the hollow shaft. The front steel sleeve, idler wheel, and rear steel sleeve are arranged sequentially in the front-to-back direction. The front steel sleeve and rear steel sleeve are both fixed relative to the left column.

[0013] A bearing is fitted between the idler wheel and the hollow shaft. A shoulder is provided on the front end of the hollow shaft. A front steel sleeve abuts against the shoulder. A positioning sleeve is fitted between the rear steel sleeve and the hollow shaft. A nut is provided on the rear end of the hollow shaft.

[0014] The buffer noise reduction collection basket also includes a noise reduction bar shaft, a second power output mechanism, and multiple noise reduction units. The multiple noise reduction units are arranged at intervals along the axial direction of the noise reduction bar shaft. Each noise reduction unit contains a connecting wheel and an elastic noise reduction bar connected in sequence. The noise reduction bar shaft is parallel to the buffer chain shaft and passes through the connecting wheel of each noise reduction unit. The second power output mechanism can drive the connecting wheel and the elastic noise reduction bar to rotate through the noise reduction bar shaft. When the elastic noise reduction bar is in the receiving position, the elastic noise reduction bar is in an inclined state. The elastic noise reduction bar can receive the long metal material and move the long metal material downward along the elastic noise reduction bar into the basket frame. When the elastic noise reduction bar rotates, the elastic noise reduction bar can bend and pass over the long metal material in the basket frame.

[0015] An idler wheel is provided above the traction wheel, and the noise reduction strip shaft passes through the idler wheel. Both the idler wheel and the connecting wheel are located on the left side of the basket frame. The axis of the idler wheel coincides with the axis of the noise reduction strip shaft. The noise reduction unit is located in front of or behind the receiving unit. The noise reduction strip shaft is connected to the left column through the second connecting seat assembly. The elastic noise reduction strip is made of rubber and is perpendicular to the noise reduction strip shaft.

[0016] The connecting wheel has a symmetrically arranged lower half wheel body and an upper half wheel body. One end of the elastic noise reduction strip is connected and fixed to the lower half wheel body by a pressure plate and screws. The second connecting seat assembly has an outer spherical ball bearing and a mounting plate connected in sequence. The outer spherical ball bearing and the mounting plate are both sleeved on the outside of the noise reduction strip shaft. The fixing plate is connected and fixed to the frame.

[0017] The basket frame also includes a crossbeam and a sloping platform. The crossbeam is located at the bottom of the basket frame. The left end of the crossbeam is connected and fixed to the left upright, and the right end of the crossbeam is connected and fixed to the right upright. The upper end of the left upright is lower than the upper end of the right upright. The sloping platform is located above the left upright and can guide long metal pieces to roll into the basket frame.

[0018] The basket frame also includes left and right diagonal braces symmetrically arranged on the left and right sides of the crossbeam. The two ends of the left diagonal brace are connected and fixed to the left column and the crossbeam respectively, and the angle between the left diagonal brace and the crossbeam is 60°. The two ends of the right diagonal brace are connected and fixed to the right column and the crossbeam respectively, and the angle between the right diagonal brace and the crossbeam is also 60°.

[0019] The beneficial effects of this invention are: the buffered noise-reducing collection basket can effectively solve the noise problem of round bar or steel pipe collection baskets, is stable and reliable, easy to operate, facilitates bundling of collected materials, and has a good noise reduction effect. It meets the environmental protection requirements of steel plants and greatly reduces the impact of noise on the health of operators. Attached Figure Description

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] A buffered noise-reducing collection basket includes a buffer chain shaft 22, a first power output mechanism 2, and multiple collection units. The collection units are spaced apart along the axial direction of the buffer chain shaft 22. Each collection unit includes a basket frame 1, a pull wheel 24, and a buffer chain 23. The basket frame 1 includes a left column 14 and a right column 12 spaced apart. One end of the buffer chain 23 is connected to the right column 12, and the other end is connected to the pull wheel 24. The working section of the buffer chain 23 is located between the left column 14 and the right column 12, and can support long metal materials 5. The buffer chain shaft 22 passes through the pull wheel 24 of each collection unit. The first power output mechanism 2 can drive the pull wheel 24 to rotate via the buffer chain shaft 22. When the pull wheel 24 rotates, it can retract or extend the buffer chain 23. Figure 1 and Figure 2 As shown.

[0034] Initially, the working section of the buffer chain 23 is roughly horizontal and located at the top of the basket frame 1. A portion of the buffer chain 23 is wound around the traction wheel 24. Metal long pieces 5 (metal rods or tubes) falling into the basket frame 1 are caught by the working section of the buffer chain 23, meaning the metal long pieces 5 fall directly onto the working section of the buffer chain 23, reducing the impact noise caused by the metal long pieces 5 directly hitting the basket frame 1. As the number of metal long pieces 5 falling into the basket frame 1 increases, multiple metal long pieces 5 form a metal long piece pile on the working section of the buffer chain 23. Simultaneously, the first power output mechanism 2 drives the buffer chain shaft 22 and the traction wheel 24 to rotate slowly and uniformly clockwise around the axis of the buffer chain shaft 22, gradually releasing the buffer chain 23 wound around the traction wheel 24, making the working section of the buffer chain 23 longer and U-shaped. The upper surface of the metal long piece pile slowly moves downward, thereby reducing the noise generated by the collision between the metal long pieces 5.

[0035] In this embodiment, the buffer chain shaft 22 is horizontal, and its axis is set along the front-to-back direction. The buffer chain shaft 22 is located on the left side of the left column 14. The buffer chain shaft 22 is connected to the frame 1 through the bearing seat 28. One end of the buffer chain 23 is connected to the upper part of the right column 12. A counterweight 26 is provided on the working section of the buffer chain 23.

[0036] A bearing is fitted between the buffer chain shaft 22 and the bearing seat 28. The bearing seat 28 is connected and fixed to the lower end of the left upright 14 of the frame 1. The right end of the buffer chain 23 is connected and fixed to the upper end of the right upright 12 via a hinge 27. The left end of the buffer chain 23 is connected and fixed to the edge of the traction wheel 24 via a pin. Figure 2 As shown. The buffer chain shaft 22 is perpendicular to the left column 14, and the left column 14 is parallel to the right column 12.

[0037] In one of the receiving units, an idler wheel 25 is provided above the traction wheel 24. Both the idler wheel 25 and the traction wheel 24 are located on the left side of the basket frame 1. The axis of the idler wheel 25 is parallel to the axis of the traction wheel 24. The idler wheel 25 is connected to the left column 14 through the first connecting seat assembly. The buffer chain 23 rests on the idler wheel 25.

[0038] Both the idler wheel 25 and the traction wheel 24 can be sprockets. The buffer chain 23 meshes with the idler wheel 25 and the traction wheel 24. The idler wheel 25 and the traction wheel 24 are located in the same vertical plane. The buffer chain 23 passes around the idler wheel 25. When the traction wheel 24 rotates, it can drive the idler wheel 25 (with the axis of the idler wheel 25 as the axis) to rotate synchronously. The upper end of the idler wheel 25 is slightly lower than the upper end of the left column 14. The metal elongated member 5 enters the frame 1 from above the left column 14.

[0039] In this embodiment, the first connecting seat assembly includes a hollow shaft 37, a front steel sleeve 17, and a rear steel sleeve 16. The front steel sleeve 17, idler wheel 25, and rear steel sleeve 16 are all sleeved on the hollow shaft 37. The front steel sleeve 17, idler wheel 25, and rear steel sleeve 16 are arranged sequentially in the front-to-back direction. The front steel sleeve 17 and rear steel sleeve 16 are both fixed relative to the left column 14. The front steel sleeve 17 and rear steel sleeve 16 can be directly connected and fixed to the left column 14, or they can be connected and fixed to the left column 14 via connectors. Figure 3 As shown.

[0040] In this embodiment, the axis of the hollow shaft 37 coincides with the axis of the idler wheel 25. Two bearings 29 are sleeved between the idler wheel 25 and the hollow shaft 37. The front end of the hollow shaft 37 is provided with a shoulder, and the front steel sleeve 17 abuts against the shoulder. The rear steel sleeve 16 is sleeved with a positioning sleeve 35 between the hollow shaft 37 and the rear end of the hollow shaft 37 is provided with a nut 36. The bearings 29, the positioning sleeve 35 and the nut 36 abut against each other in sequence. Tightening the nut 36 can prevent the idler wheel 25 from moving along the axial direction of the hollow shaft 37.

[0041] In each of the receiving units, the basket frame 1 includes two left uprights 14 arranged front to back and two right uprights 12 arranged front to back. A front steel sleeve 17 is connected and fixed to the front left upright 14 via a connector, and a rear steel sleeve 16 is connected and fixed to the rear left upright 14 via a connector. An idler wheel 25 and a traction wheel 24 are both located between the two left uprights 14. The first connecting seat assembly is located on the left side of the left upright 14. Figure 3 As shown.

[0042] In this embodiment, the buffer noise reduction collection basket further includes a noise reduction bar shaft 32, a second power output mechanism 3, and multiple noise reduction units 4. The multiple noise reduction units 4 are arranged at intervals along the axial direction of the noise reduction bar shaft 32. Each noise reduction unit 4 contains a connecting wheel 44 and an elastic noise reduction bar 40 connected in sequence. The noise reduction bar shaft 32 is parallel to the buffer chain shaft 22, and passes through the connecting wheel 44 of each noise reduction unit 4. The second power output mechanism 3 can drive the connecting wheel 44 and the elastic noise reduction bar 40 to rotate via the noise reduction bar shaft 32. When the elastic noise reduction bar 40 is in the receiving position, the elastic noise reduction bar 40 is in an inclined state, such as... Figure 2 As shown, the elastic noise reduction strip 40 can support the metal long piece 5 and move the metal long piece 5 downward along the elastic noise reduction strip 40 into the basket frame 1; when the elastic noise reduction strip 40 rotates, the elastic noise reduction strip 40 can bend and pass over the metal long piece 5 inside the basket frame 1.

[0043] The second power output mechanism 3 enables the noise-reducing strip shaft 32, connecting wheel 44, and elastic noise-reducing strip 40 to rotate around the axis of the noise-reducing strip shaft 32. The function of the elastic noise-reducing strip 40 is that, as the number of metal long pieces 5 falling into the basket 1 increases, multiple metal long pieces 5 accumulate on the working section of the buffer chain 23 to form a metal long piece pile. The upper surface of the metal long piece pile slowly moves downward, and the metal long pieces 5 falling into the basket 1 will first hit the elastic noise-reducing strip 40, and then roll down along the elastic noise-reducing strip 40 onto the metal long piece pile inside the basket 1. Then, the second power output mechanism 3 causes the elastic noise-reducing strip 40 to rotate 360°, allowing the elastic noise-reducing strip 40 to bend and pass over the metal long piece pile inside the basket 1, returning to its original position. Figure 2 At the material receiving position shown, the elastic noise reduction strip 40 can reduce the noise generated by the metal longs 5 ​​directly hitting the metal longs pile.

[0044] In this embodiment, the noise reduction strip shaft 32 passes through the idler wheel 25 and the hollow shaft 37. The outer diameter of the noise reduction strip shaft 32 is smaller than the inner diameter of the hollow shaft 37. There is no contact or connection between the noise reduction strip shaft 32 and the hollow shaft 37. The noise reduction strip shaft 32 and the hollow shaft 37 rotate independently without interfering with each other. The hollow shaft 37, the idler wheel 25, and the connecting wheel 44 are all located on the left side of the basket frame 1. The axis of the idler wheel 25, the axis of the hollow shaft 37, and the axis of the noise reduction strip shaft 32 coincide. The noise reduction strip shaft 32 and the buffer chain shaft 22 are arranged vertically parallel. The noise reduction unit 4 is located in front of or behind the receiving unit. The noise reduction strip shaft 32 is connected to the left column 14 through the second connecting seat assembly. The elastic noise reduction strip 40 is made of rubber and is perpendicular to the noise reduction strip shaft 32.

[0045] In this embodiment, the connecting wheel 44 is fixedly connected to the noise reduction strip shaft 32. The connecting wheel 44 includes a symmetrically arranged lower half wheel body 42 and an upper half wheel body 43. The lower half wheel body 42 and the upper half wheel body 43 are connected by bolts. One end of the elastic noise reduction strip 40 is fixedly connected to the lower half wheel body 42 by a pressure plate 41 and screws. Figure 4 As shown. The second connecting seat assembly includes an outer spherical ball bearing 33 connected in sequence and a mounting plate 34. Both the outer spherical ball bearing 33 and the mounting plate 34 are sleeved on the outside of the noise reduction strip shaft 32. The mounting plate 34 is connected and fixed to the frame 1.

[0046] Each receiving unit contains two second connecting seat assemblies arranged front and rear. The fixing plate 34 of the front second connecting seat assembly is fixed to the front left column 14 by bolts, and the fixing plate 34 of the rear second connecting seat assembly is welded to the rear left column 14. A hollow shaft 37 is located between the two second connecting seat assemblies, as shown below. Figure 3 As shown

[0047] In this embodiment, the basket frame 1 also includes a crossbeam 11 and a sloping platform 10. The crossbeam 11 is horizontal and located at the lower part of the basket frame 1. The left end of the crossbeam 11 is welded and fixed to the lower end of the left column 14, and the right end of the crossbeam 11 is welded and fixed to the lower end of the right column 12. The upper end of the left column 14 is lower than the upper end of the right column 12. The sloping platform 10 is located above the left column 14 and is welded to the left column 14. The upper surface of the sloping platform 10 is higher on the left and lower on the right, and the upper surface of the sloping platform 10 is higher than the upper end of the left column 14. The sloping platform 10 can guide the metal elongated material 5 to roll into the basket frame 1.

[0048] In this embodiment, the frame 1 also includes a left diagonal brace 15 and a right diagonal brace 13 symmetrically arranged on the left and right sides of the crossbeam 11. The left diagonal brace 15 and the right diagonal brace 13 have the same structure and are mirror images of each other. The two ends of the left diagonal brace 15 are welded and fixed to the left upright 14 and the crossbeam 11, respectively. The angle between the left diagonal brace 15 and the crossbeam 11 is 60°. The two ends of the right diagonal brace 13 are welded and fixed to the right upright 12 and the crossbeam 11, respectively. The angle between the right diagonal brace 13 and the crossbeam 11 is also 60°. The left diagonal brace 15 and the right diagonal brace 13 work together with the crossbeam 11 to bundle and shape (three sides at the bottom, usually six sides forming a bundle, divided into upper and lower three sides), such as... Figure 2 As shown.

[0049] In this embodiment, the first power output mechanism 2 includes a buffer chain reduction motor 20 and a buffer chain coupling 21. The buffer chain reduction motor 20, the buffer chain coupling 21, and the buffer chain shaft 22 are connected in sequence. The buffer chain reduction motor 20 can drive the buffer chain shaft 22 to rotate evenly and slowly. The buffer chain reduction motor 20 can be a low-power reduction motor, and a brake can be used to lock the chain droop length, thereby effectively improving the service life of the gearbox gears; or an openable ratchet can be used to lock the chain droop length. When the chain is in place, the ratchet that was originally open will engage and lock.

[0050] In this embodiment, the second power output mechanism 3 includes a noise-reducing strip geared motor 30 and a noise-reducing strip coupling 31. The noise-reducing strip geared motor 30, the noise-reducing strip coupling 31, and the noise-reducing strip shaft 32 are connected in sequence. The noise-reducing strip geared motor 30 can drive the noise-reducing strip shaft 32 to rotate 360° each time, so that the elastic noise-reducing strip 40 can return to its original position after each connection with a metal long piece 5. Figure 2 The material receiving location is shown.

[0051] The material of the elastic noise reduction strip 40 can be selected from existing technology materials. For example, the material requirements of the elastic noise reduction strip 40 can comply with DIN 22102 (German standard for layered conveyor belts), but are not limited to the materials of this standard. When the material of the elastic noise reduction strip 40 is a steel cord conveyor belt, the strength range of the elastic noise reduction strip 40 can be 630N / mm-10000N / mm; when the material of the elastic noise reduction strip 40 is a layered fabric core conveyor belt, the strength range of the elastic noise reduction strip 40 can be 100N / mm-630N / mm; when the material of the elastic noise reduction strip 40 is a solid woven flame-retardant conveyor belt, the strength range of the elastic noise reduction strip 40 can be 680N / mm-4000N / mm.

[0052] The elastic noise reduction strip 40 should possess sufficient strength and toughness to ensure that the metal long piece 5 can slide downwards after hitting it, and also to allow the elastic noise reduction strip 40 to bend and pass over the pile of metal long pieces after rotation. The specific dimensions of the elastic noise reduction strip 40 can be determined based on the outer diameter and weight of the metal long piece 5, as well as through a limited number of experiments, with the aim of achieving effective cushioning.

[0053] The working process of this buffer noise reduction collection basket is described below.

[0054] Initially, the working section of the buffer chain 23 is roughly horizontal, located at the upper part of the frame 1, with a portion of the buffer chain 23 wound around the traction wheel 24, such as... Figure 2 As shown, the long metal piece 5 rolls down from the inclined platform 10 into the basket frame 1. Once inside the basket frame 1, the long metal piece 5 is caught by the working section of the buffer chain 23, meaning it lands directly on the working section of the buffer chain 23. At this point, the elastic noise-reducing strip 40 is in the receiving position, but the long metal piece 5 does not yet land directly on it. Because the vertical distance between the working section of the buffer chain 23 and the right end of the inclined platform 10 is small, the distance the long metal piece 5 travels during its free fall is also relatively small, thus reducing the impact noise generated when the long metal piece 5 lands directly on the bottom of the basket frame 1.

[0055] As the number of metal long pieces 5 falling into the frame 1 increases, multiple metal long pieces 5 accumulate on the working section of the buffer chain 23, forming an inverted trapezoidal pile of metal long pieces, such as... Figure 5 and Figure 6 As shown. Simultaneously, the first power output mechanism 2 drives both the buffer chain shaft 22 and the traction wheel 24 to rotate slowly and uniformly clockwise around the axis of the buffer chain shaft 22, gradually releasing the buffer chain 23 wound around the traction wheel 24, causing the working section of the buffer chain 23 to lengthen and form a U-shape. Figure 6(Not shown in the image), the working section of the buffer chain 23 matches and adheres to the lower side of the metal long material pile, and the upper surface of the metal long material pile slowly moves downward. The metal long material 5 falling into the basket 1 will first hit the elastic noise reduction strip 40, and then roll down along the elastic noise reduction strip 40 onto the metal long material pile inside the basket 1. Then, the second power output mechanism 3 causes the elastic noise reduction strip 40 to rotate 360°, allowing the elastic noise reduction strip 40 to bend and pass over the metal long material pile inside the basket 1, returning the elastic noise reduction strip 40 to the receiving position. The elastic noise reduction strip 40 can reduce the noise generated by the metal long material 5 directly hitting the metal long material pile. Each time the elastic noise reduction strip 40 receives a metal long material 5, the second power output mechanism 3 causes the elastic noise reduction strip 40 to rotate 360°. The elastic noise reduction strip 40 can reduce the noise generated by the metal long material 5 directly hitting the metal long material pile.
