Description

Technical Field

[0001] The invention belongs to the technical field of noise reduction in steel pipe workshops, and in particular relates to a noise reduction device for reducing noise during the transportation of steel pipes. Background Art

[0002] In the existing technology, workshop noise has always been a major problem. It not only affects the quality of the visit, but also causes noise damage due to excessive noise.

[0003] The noise in the steel pipe workshop is mainly caused by the collision between steel pipes during the transportation of large-diameter production lines. The processes are mainly connected by slope slides, and the steel pipes are moved from one process to another by rolling freely on the ramp. In this way, the steel pipes collide with the previous steel pipes during free rolling, which will produce noise. The noise in the workshop not only affects the surrounding environment, but also causes certain harm to the workers' health.

[0004] The noise reduction of the steel pipes at the drying kang is more difficult than that in other areas. There are heating pipes under the steel pipes of the drying kang, and there is no space for adding equipment.

[0005] The noise in the passivation discharge pipe area is mainly emitted by the steel pipe hitting the baffle. Since the steel pipe has acceleration when it is transmitted, it can only achieve instantaneous deceleration through impact. When the steel pipe hits the baffle, it can only be reduced by cotton pads or rubber pads, but the effect is very poor.

[0006] The noise in the packaging area is mainly caused by the collision between steel pipes. Since the steel pipes need to be temporarily stored in the packaging area, the existing technology directly uses the slope to hit the steel pipe directly against the previous steel pipe to concentrate them together, and the collision sound between the steel pipes is very loud. Summary of the invention

[0007] The problem to be solved by the present invention is to provide a noise reduction device for reducing the noise during the transportation of steel pipes, which effectively solves the problem in the prior art that noise is generated when a steel pipe hits the previous steel pipe during free rolling, and the noise in the workshop not only affects the surrounding environment, but also causes certain harm to the workers' health.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is: a noise reduction device for reducing noise during steel pipe transportation, including: a noise reduction module in the drying pit pipe placing area, a noise reduction module in the passivation pipe placing area and a noise reduction module in the packaging area. The steel pipe is first conveyed by the steel pipe conveying device to the noise reduction module in the drying pit pipe placing area, and then conveyed to the noise reduction module in the passivation pipe placing area through a chain conveyor belt, and finally conveyed to the noise reduction module in the packaging area through a roller.

[0009] Furthermore, the noise reduction module of the drying pit pipe area includes a transmission mechanism, a fixing mechanism arranged on the transmission mechanism, a connecting mechanism connected to the fixing mechanism, and a noise reduction mechanism installed at the bottom of the connecting mechanism;

[0010] Wherein, the transmission mechanism comprises a driving member and a guide rail arranged on one side of the driving member;

[0011] Both sides of the fixing mechanism are connected to the guide rail, and the driving member can drive the fixing mechanism to move freely along the guide rail;

[0012] One end of the connecting mechanism is connected to the fixing mechanism, and the other end is connected to the noise reduction mechanism. When the driving member drives the fixing mechanism to move on the guide rail, the fixing mechanism drives the connecting mechanism to move together, and then drives the noise reduction mechanism to move between the steel pipes, thereby reducing the noise caused by collision between the steel pipes.

[0013] Further, the fixing mechanism includes a fixing rod and a first fixing frame and a second fixing frame arranged on both sides of the fixing rod, the first fixing frame and the second fixing frame are connected to the driving member at a side away from the fixing rod, and both sides of the fixing rod are mounted on the guide rail;

[0014] The driving member drives the first fixing frame and the second fixing frame to move, thereby driving the fixing rod to move on the guide rail;

[0015] The connecting mechanism includes a telescopic member for controlling the height of the noise reduction mechanism and a connecting rod connected to the telescopic member; one end of the telescopic member is connected to the fixing mechanism, and the other end is connected to the connecting rod, and the end of the connecting rod away from the telescopic member is connected to the noise reduction mechanism;

[0016] The noise reduction mechanism includes a noise reduction pad, one end of which is connected to a side of the connecting rod away from the fixing mechanism, and is used to buffer the collision between the steel pipes and reduce noise;

[0017] Preferably, it further comprises a first control mechanism for controlling the upward and downward movement of the telescopic member, the first control mechanism being arranged on the fixing mechanism and close to the telescopic member; when the second steel pipe hits the first steel pipe, the telescopic member keeps the noise reduction mechanism between the second steel pipe and the first steel pipe, and after the impact is completed, the first control mechanism controls the telescopic member to drive the noise reduction mechanism to move upward, and the second steel pipe contacts the first steel pipe;

[0018] More preferably, the first control mechanism is also used to control the movement of the transmission mechanism. When the second steel pipe contacts the first steel pipe, the first control mechanism controls the transmission mechanism to move from the position between the first steel pipe and the second steel pipe to the direction away from the first steel pipe, driving the noise reduction mechanism to move to the position where the second steel pipe is away from the first steel pipe, and controls the telescopic part to drive the noise reduction mechanism to move downward, so that the noise reduction mechanism can just contact the surface of the second steel pipe.

[0019] Furthermore, it also includes a second control mechanism for controlling the moving direction of the transmission mechanism, and the second control mechanism is arranged on the guide rail;

[0020] Preferably, the second control mechanism is a first sensor, which is arranged at the edge positions of the guide rails near both ends. When the steel pipe begins to be laid, the first sensor controls the transmission mechanism to start moving; when the steel pipe is about to finish laying, the first sensor controls the transmission mechanism to stop moving.

[0021] Furthermore, the passivation pipe area noise reduction module includes a support member, one end of which is an open port for connecting the steel pipe conveying device, and the other end is provided with a protective member for the steel pipe to hit; a conveying member, the conveying member includes a magnetic roller for conveying the steel pipe, and is arranged on the support member; a rotating member, which is arranged on the support member and does not overlap with the transmission member, and is used to move the steel pipe;

[0022] Preferably, both ends of the magnetic roller for conveying the steel pipe are connected to both sides of the support member for conveying the steel pipe.

[0023] Further, the support member includes a first support frame, a second support frame arranged on the opposite side of the first support frame, and a connecting frame connecting the first support frame and the second support frame, and is used to support the protective member, the transmission member and the rotating member;

[0024] The protection member includes a baffle for the steel pipe device and a first protection frame to prevent the steel pipe from falling, the baffle is arranged at one end of the support member, and the first protection frame is arranged on the support members on both sides of the baffle;

[0025] The rotating member includes a rotating shaft and a rotating wheel sleeved on the rotating shaft, wherein the rotating shaft is arranged on a side of the supporting member close to the ground, and the rotating wheel is arranged in the supporting member and does not overlap with the transmission member; when the steel pipe is transferred to the transmission member and stops moving, the rotating wheel moves the steel pipe to move the steel pipe out of the passivation pipe placing device through the pipe outlet;

[0026] Among them, at least one lever for moving the steel pipe is arranged around the rotating wheel. When the rotating shaft drives the rotating wheel to rotate, the lever moves the steel pipe to move the steel pipe out of the passivation pipe placing device.

[0027] Furthermore, the protective member includes a baffle for the steel pipe device and a first protective frame to prevent the steel pipe from falling, the baffle is arranged at one end of the support member, the first protective frame is arranged on the support members on both sides of the baffle, and the height of the first protective frame is higher than the height of the baffle; preferably, the protective member also includes a second protective frame arranged on the side of the support member away from the pipe outlet to prevent the steel pipe from falling during the transmission process

[0028] Further, the packaging area noise reduction module includes a support portion and a transmission portion arranged between the support portions;

[0029] The support part includes at least two packaging support frames for carrying the steel pipe;

[0030] The conveying part includes a device supporting rod and a bearing part arranged on the supporting rod. The steel pipe is conveyed to the bearing part through the roller. The supporting rod lifts up the steel pipe and transports the steel pipe to a position adjacent to the previous steel pipe. The supporting rod falls to a position where the bearing part is lower than the packaging support frame, and the steel pipe is placed on the packaging support frame.

[0031] Furthermore, the conveying part also includes a packaging lifting cylinder arranged at the bottom of the support rod, a conveying wheel installed at the bottom of the lifting cylinder, and a conveying motor controlling the rotation of the conveying wheel; the lifting cylinder is used to lift or lower the support rod and the load-bearing part, and the conveying motor controls the conveying wheel to move the support rod toward or away from the previous steel pipe, and cooperates with the lifting cylinder to transport the steel pipe.

[0032] Furthermore, it also includes a steel pipe sensor arranged on the packaging support frame. When the steel pipe is transmitted to a side close to the packaging support frame, the steel pipe sensor controls the lifting cylinder to rise; when the steel pipe is transmitted to a position close to the previous steel pipe, the steel pipe sensor controls the lifting cylinder to descend.

[0033] By adopting the above technical solution, the transmission mechanism can drive the fixing mechanism to move forward and backward, and then drive the connecting mechanism and the noise reduction mechanism to move together. The telescopic parts in the connecting mechanism can control the noise reduction mechanism to move up and down, and can flexibly perform noise reduction processing on each steel pipe. When the next steel pipe is about to collide, the noise reduction mechanism can block between the two steel pipes, avoiding the collision of the two steel pipes and making a loud noise, and can guarantee the quality of each steel pipe to a certain extent, avoiding the external damage of the steel pipe due to collision during the transmission process, and solving the noise problem in the pipe placement area of ​​the drying pit.

[0034] By adopting the above technical scheme, a support member is used in conjunction with a conveying member to convey the steel pipe to a target position where it is decelerated and stopped, and then the steel pipe is transferred to the position of the next process through a rotating member, and a protective member is arranged around the support member to prevent the steel pipe from suddenly falling due to excessive speed or problems with the passivation device. At the same time, the threat posed by the falling steel pipe to the workers is eliminated, creating a safe working environment, and reducing the loss of steel pipes caused by falling steel pipes. While being safe, it can also save production costs and solve the noise problem in the passivation pipe release area.

[0035] By adopting the above technical solution, the conveying part lifts the steel pipe and then moves it, and then places the steel pipe on the supporting part at a position close to the previous steel pipe. This can greatly reduce the device noise between the steel pipes, and can avoid external damage to the steel pipe due to collision during the conveying process, thereby solving the noise problem in the packaging area.

In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0055] like Figure 6As shown, a noise reduction device for reducing noise during steel pipe transportation includes: a noise reduction module in a drying pit pipe placing area, a noise reduction module in a passivation pipe placing area, and a noise reduction module in a packaging area. The steel pipe is first conveyed by a steel pipe conveying device to the noise reduction module in the drying pit pipe placing area, then conveyed to the noise reduction module in the passivation pipe placing area by a chain conveyor belt, and finally conveyed to the noise reduction module in the packaging area by a roller.

[0056] Among them, Figure 1 and Figure 2 As shown, the noise reduction module of the drying pit pipe area includes:

[0057] The transmission mechanism includes a driving member 1-1 and a guide rail 1-2 arranged on one side of the driving member 1-1; the driving member 1-1 is arranged on both sides of the drying pit, and the number of the guide rails 1-2 is 2, which are arranged between the driving members 1-1 on both sides respectively, and the driving members 1-1 close to the two sides can support the fixing rod 1-5 to stably slide on the guide rail 1-2; the distance between the two guide rails 1-2 is greater than the size of the fixing mechanism, so that the fixing mechanism can move freely on the guide rail 1-2 without affecting the movement of the fixing mechanism;

[0058] The two sides of the fixing mechanism are connected to the guide rails 1-2, and the driving member 1-1 can drive the fixing mechanism to move freely along the guide rails 1-2;

[0059] One end of the connecting mechanism is connected to the fixing mechanism, and the other end is connected to the noise reduction mechanism. When the driving member 1-1 drives the fixing mechanism to move on the guide rail 1-2, the fixing mechanism drives the connecting mechanism to move together, and then drives the noise reduction mechanism to move between the steel pipes, reducing the noise caused by collision between the steel pipes.

[0060] Specifically, the fixing mechanism includes a fixing rod 1-5 and a first fixing frame 1-3 and a second fixing frame 1-4 arranged on both sides of the fixing rod 1-5; the material of the fixing rod 1-5 can be steel material or other materials, preferably steel material, the shape of the fixing rod 1-5 can be rectangular, cylindrical or other shapes, preferably cylindrical, the length of the fixing rod 1-5 is greater than the distance between the two guide rails 1-2 and less than the distance between the two driving members 1-1; both sides of the fixing rod 1-5 are respectively mounted on the guide rails 1-2, and the driving member 1-1 drives the fixing rod 1-5 to move back and forth on the guide rail 1-2;

[0061] One side of the first fixing frame 1-3 and the second fixing frame 1-4 are respectively connected to the two ends of the fixing rod 1-5, and the side away from the fixing rod 1-5 is respectively connected to the driving members 1-1 on both sides. The material of the first fixing frame 1-3 and the second fixing frame 1-4 can be steel material or other materials, preferably steel material. The shape of the first fixing frame 1-3 and the second fixing frame 1-4 can be cylindrical, rectangular or other shapes, preferably cylindrical. Both sides of the fixing rod 1-5 are mounted on the guide rail 1-2, and the driving member 1-1 connects the fixing rod 1-5 through the first fixing frame 1-3 and the second fixing frame 1-4, drives the first fixing frame 1-3 and the second fixing frame 1-4 to move, and then drives the fixing rod 1-5 to move accordingly, so that the fixing rod 1-5 moves freely on the guide rail 1-2 under the drive of the driving member 1-1.

[0062] The connecting mechanism includes a telescopic member 1-6 for controlling the height of the noise reduction mechanism and a connecting rod 1-7 connected to the telescopic member 1-6; one end of the telescopic member 1-6 is welded to the middle position of the fixing mechanism, and the other end is connected to the connecting rod 1-7. The telescopic member 1-6 is telescopically displaced according to the required height of the noise reduction mechanism to control the height of the noise reduction mechanism;

[0063] One end of the connecting rod 1-7 is connected to the end of the telescopic rod 1-6 away from the fixed rod 1-5, and the end of the connecting rod 1-7 away from the telescopic part 1-6 is connected to the noise reduction mechanism. The material of the connecting rod 1-7 can be steel or other materials. The shape of the connecting rod 1-7 can be rectangular, cylindrical or other shapes. The length of the connecting rod 1-7 is shorter than the distance between the bottom end of the telescopic part 1-6 and the steel pipe, and the length of the connecting rod 1-7 is longer than the distance between the bottom end of the telescopic rod 1-6 extended to the maximum length and the steel pipe, ensuring that the noise reduction mechanism can block the collision between the two steel pipes, thereby reducing noise.

[0064] In some feasible embodiments, the telescopic members 1-6 are telescopic cylinders.

[0065] The noise reduction mechanism includes a noise reduction pad 1-8, one end of which is connected to the side of the connecting rod 1-7 away from the fixed rod 1-5, and is used to buffer the collision between the steel pipes and reduce noise. The material of the noise reduction pad 1-8 can be rubber, silicone or other soft materials with a certain toughness. The length of the noise reduction pad 1-8 only needs to be greater than the radius of the steel pipe, and is preferably slightly greater than the diameter of the steel pipe. It can ensure that when two steel pipes collide, the noise reduction pad 1-8 is blocked between the two steel pipes to prevent the collision of the two steel pipes from generating noise and reduce the noise hazards in the factory.

[0066] In some feasible embodiments, the noise reduction device also includes a second control mechanism 1-9 for controlling the moving direction of the transmission mechanism. The second control mechanism 1-9 is arranged on the guide rail 1-2. The number of the second control mechanisms 1-9 is at least 2, which are respectively arranged at both ends of the guide rail 1-2, sensing the positions of the steel pipe and the fixed rod 1-5.

[0067] The second control mechanism 1-9 is the first sensor, which is arranged at the edge positions of the guide rail 1-2 near both ends. When the steel pipe begins to be laid, the first sensor controls the driving component 1-1 to drive the fixed rod 1-5 to start moving, and the fixed rod 1-5 drives the connecting mechanism to move, and then drives the noise reduction mechanism to move; when the steel pipe is about to finish laying, the first sensor controls the driving component 1-1 to stop driving, and the fixed rod 1-5 and the connecting mechanism and the noise reduction mechanism also stop moving.

[0068] In some feasible embodiments, the noise reduction device also includes a first control mechanism 1-10 for controlling the upward and downward movement of the telescopic member 1-6. The first control mechanism 1-10 is arranged on the fixed rod 1-5 and is located close to the telescopic member 1-6. When the second steel pipe hits the first steel pipe, the telescopic member 1-6 keeps the noise reduction mechanism stationary between the second steel pipe and the first steel pipe. After the collision is completed, the first control mechanism 1-10 controls the telescopic member 1-6 to drive the noise reduction mechanism to move upward, and the second steel pipe contacts the first steel pipe.

[0069] The first control mechanism 1-10 is also used to control the movement of the driving member 1-1. When the second steel pipe contacts the first steel pipe, the first control mechanism 1-10 controls the driving member 1-1 to drive the fixing rod 1-5 and the connecting mechanism to move from the position between the first steel pipe and the second steel pipe to the direction away from the first steel pipe, thereby driving the noise reduction mechanism to move to the position where the second steel pipe is away from the first steel pipe, and controlling the telescopic member 1-6 to drive the noise reduction mechanism to move downward. The noise reduction mechanism can just contact the surface of the second steel pipe to prepare for the impact of the next steel pipe. When the next steel pipe is about to impact, repeat the above operation.

[0070] In some feasible embodiments, the first control mechanism 1 - 10 is a second sensor.

[0071] The transmission mechanism can drive the fixing mechanism to move forward and backward, and then drive the connecting mechanism and the noise reduction mechanism to move together. The telescopic parts 1-6 in the connecting mechanism can control the noise reduction mechanism to move up and down, and can flexibly perform noise reduction processing on each steel pipe. When the next steel pipe is about to collide, the noise reduction mechanism can block between the two steel pipes to avoid the collision of the two steel pipes and produce a loud noise. It can also guarantee the quality of each steel pipe to a certain extent and avoid external damage to the steel pipe due to collision during the transmission process.

[0072] The second control mechanism 1-9 and the first control mechanism 1-10 can replace manual control of the transmission mechanism and the telescopic member 1-6, which greatly reduces the labor cost, and also reduces the influence of manual factors, improves the corresponding work efficiency, and blocks the collision between steel pipes and reduces noise during the reciprocating cycle.

[0073] like Figure 3 As shown in Figure 4, the noise reduction module of the passivation tube area includes:

[0074] The support member has an open port at one end for connecting to a steel pipe conveying device, which is the pipe inlet; the other end and one side of the support member are provided with a protective member for the steel pipe to hit, and the other side is also an open channel, which is the pipe outlet;

[0075] The conveying member includes a magnetic roller 8 for conveying the steel pipe, which is arranged on the supporting member;

[0076] The rotating member is arranged on the supporting member and does not overlap with the transmission member, and is used for moving the steel pipe.

[0077] Specifically, the support member includes a first support frame 2-1, a second support frame 2-2 arranged on the opposite side of the first support frame 2-1, and a connecting frame 2-3 connecting the first support frame 2-1 and the second support frame 2-2. The first support frame 2-1 is made of steel or other materials, and needs to have a certain hardness and supporting capacity, so that it can withstand the mass of transmission parts, protective parts, rotating parts and steel pipes without deformation; the shape of the first support frame 2-1 is rectangular, cylindrical or other shapes, and the length of the first support frame 2-1 is required to be longer than the length of the steel pipe to be transported, so that the steel pipe can be smoothly transported to the next process.

[0078] The material selection range of the second support frame 2-2 is consistent with that of the first support frame 2-1, and is preferably a material consistent with the first support frame 2-1; the shape selection range of the second support frame 2-2 is consistent with that of the first support frame 2-1, and is preferably a material consistent with the second support frame 2-2; the length requirement of the second support frame 2-2 is consistent with that of the first support frame 2-1, and is preferably a length consistent with the first support frame 2-1.

[0079] One end of the connecting frame 2-3 is connected to the first support frame 2-1, and the other end is connected to the second support frame 2-2. After the three parts are assembled, the whole is in the shape of a ladder. The material of the connecting frame 2-3 is consistent with the selection range of the first support frame 2-1, preferably consistent with the material of the first support frame 2-1. The shape of the connecting frame 2-3 is consistent with the selection range of the first support frame 2-1, preferably consistent with the shape of the first support frame 2-1; the length of the connecting frame 2-3 is consistent with the distance between the first support frame 2-1 and the second support frame 2-2, and the distance between the second support frame 2-2 and the first support frame 2-1 is at least greater than the length of the magnetic roller in the conveying member, so as to ensure that the conveying member can run smoothly between the first support frame 2-1 and the second support frame 2-2. The first support frame 2-1, the second support frame 2-2 and the connecting frame 2-3 form a support member for supporting the protective member, the conveying member and the rotating member.

[0080] The protective part includes a baffle for the steel pipe device and a first protective frame 2-4 to prevent the steel pipe from falling. The baffle 2-6 is arranged at one end of the support member, and the first protective frame 2-4 is arranged on the support members on both sides of the baffle 2-6; the material of the baffle 2-6 is selected from steel material or other materials, and the shape of the baffle 2-6 is rectangular, circular or other shapes, as long as it can completely withstand the impact of the steel pipe; the size of the baffle 2-6 is equal to or slightly larger than the cross-sectional area formed by the end of one side of the first support frame 2-1 and the second support frame 2-2, blocking the exit. If there is a problem with the conveying part, the steel pipe needs to hit the baffle 2-6 to ensure that the steel pipe does not fall.

[0081] The overall shape of the first protective frame 2-4 is similar to a football goal. The vertical section only needs to be larger than the size of the baffle 2-6, and the length of the transverse section must be at least larger than the thickness of the baffle 2-6, generally about 30-50cm, to ensure that the steel pipe will not pop out of the passivation pipe release device after hitting the baffle, while ensuring the safety of the staff.

[0082] In some feasible embodiments, the height of the first protection frame 2-4 is higher than the height of the baffle 2-6, ensuring that the movement range of the steel pipe does not exceed the protection range of the first protection frame 2-4.

[0083] In some feasible embodiments, the protective member also includes a second protective frame 2-5 arranged on the side of the support member away from the pipe outlet, that is, the second protective frame 2-5 is arranged on the first support frame 2-1, and the length of the second protective frame 2-5 is similar to that of the first support frame 2-1, which can be slightly longer, slightly shorter or the same. The distance between the second protective frame 2-5 and the first support frame 2-1 is smaller than the diameter of the steel pipe. When the steel pipe rolls to the side of the first support frame 2-1 due to an accident, it can be just stuck between the second protective frame 2-5 and the first support frame 2-1 and will not move to the outside of the passivation pipe release device.

[0084] In some feasible embodiments, a protective net 2-7 is further provided between the second protective frame 2-5 and the first support frame 2-1. At this time, there is no strict requirement on the distance between the first support frame 2-1 and the second protective frame 2-5, and it can be larger than the diameter of the steel pipe or smaller than the diameter of the steel pipe. The protective net 2-7 can cooperate with the second protective frame 2-5 to block the steel pipe and prevent it from falling from a height.

[0085] One end of the magnetic roller 2-8 for conveying steel pipes is connected to the first support frame 2-1, and the other end is connected to the second support frame 2-2. It is used to convey the steel pipes. When the steel pipes are conveyed to the target position, they are instantly decelerated so that the steel pipes stop on the magnetic roller 2-8, and the steel pipes are controlled not to contact the baffle 2-6.

[0086] The rotating part includes a rotating shaft 2-10 and a rotating wheel 2-11 mounted on the rotating shaft 2-10. The rotating shaft 2-10 is arranged on the side of the second support frame 2-2 close to the ground. The rotating wheel 2-11 is placed between the first support frame 2-1 and the second support frame 2-2 and does not overlap with the magnetic roller 2-8. When the steel pipe is transferred to the magnetic roller 2-8 and stops moving, the rotating wheel 2-11 moves the steel pipe and moves the steel pipe out of the passivation pipe release device through the pipe outlet to proceed to the next process.

[0087] At least one lever 2-9 for moving the steel pipe is arranged around the rotating wheel 2-11. When the rotating shaft 2-10 drives the rotating wheel 2-11 to rotate, the lever 2-9 moves the steel pipe to move the steel pipe out of the passivation pipe release device. Generally, there are 4 levers, one in each of the four directions of up, down, left and right. The radius of the rotating wheel 2-11 plus the length of the lever 2-9 is less than or equal to the distance between the rotating shaft 2-10 and the first support frame 2-1, which facilitates the normal operation of the rotating wheel 2-11.

[0088] like Figure 5 As shown, the packaging area noise reduction module includes:

[0089] Supporting parts and a conveying part arranged between the supporting parts;

[0090] Specifically, the support part includes at least two packing support frames 3-1 for carrying steel pipes; the packing support frame 1 is used to carry and temporarily cache the steel pipes, and the packing support frame 3-1 has a certain inclination angle, which can make the cached steel pipes roll to the next process by inertia; the number of the packing support frames 3-1 is at least two, which evenly support the steel pipes to prevent the steel pipes from falling, reduce the loss of steel pipes while reducing noise, and save production costs.

[0091] The conveying part includes a device support rod 3-2 and a bearing part 3-3 arranged on the support rod 3-2. The support rod 3-2 is installed between two packing support frames 3-1, and is arranged at intervals. The number is also at least two, and the steel pipe can be evenly supported; the support rod 3-2 can smoothly move up and down or even forward and backward between the packing support frames 3-1. The diameter of the support rod 3-2 is smaller than the interval between the packing support frames 3-1, so as to prevent the wear of the contact position between the support rod 3-2 and the packing support frame 3-1, and reduce the service life of the noise reduction module in the packing area;

[0092] The bearing part 3-3 is installed on the top of the support rod 3-2 and is used to support the steel pipe. The number of the bearing parts 3-3 is consistent with the number of the support rods 3-2. The shape of the bearing part 3-3 can be a curved surface, a "V" shape or other shapes, as long as it can stably fix the steel pipe; the size of the bearing part 3-3 must also be smaller than the spacing distance between the packaging support frames 3-1, and it needs to pass through the spacing between the packaging support frames 3-1 during the lifting and lowering process.

[0093] In some feasible embodiments, the conveying part also includes a lifting cylinder 3-5 arranged at the bottom of the support rod 3-2, a conveying wheel 3-7 installed at the bottom of the lifting cylinder 3-5, and a conveying motor 3-4 for controlling the rotation of the conveying wheel 3-7; the lifting cylinder 3-5 is used to lift or lower the support rod 3-2 and the bearing part 3-3, and the conveying motor 3-4 controls the conveying wheel 3-7 to move the support rod 3-2 and the lifting cylinder 3-5 toward or away from the previous steel pipe, so as to cooperate with the lifting cylinder 3-5 to transport the steel pipe.

[0094] The steel pipe is conveyed to the load-bearing part 3-3 through the roller conveyor. At this time, the lifting cylinder 3-5 drives the support rod 3-2 to extend from the gap of the packaging support frame 3-1, lift the steel pipe, and place the steel pipe on the load-bearing part 3-3. Then the conveying motor 3-4 controls the bottom conveying wheel 3-7 to rotate, driving the support rod 3-2 to transport the steel pipe to a position adjacent to the previous steel pipe. At this time, the lifting cylinder 3-5 drives the support rod 3-2 to fall to the position where the load-bearing part 3-3 is lower than the packaging support frame 3-1, and the steel pipe is placed on the packaging support frame 3-1. Then the conveying wheel 3-7 drives the support rod 3-2 back to the position where the packaging support frame 3-1 contacts the roller conveyor.

[0095] In some feasible embodiments, the packaging area noise reduction module also includes a steel pipe sensor 3-6 arranged on the packaging support frame 3-1. The number of the steel pipe sensor 3-6 is at least one, preferably two, which are respectively arranged on both sides of the packaging support frame 3-1 close to one end of the roller; when the steel pipe is transmitted from the roller to the side close to the packaging support frame 3-1, the steel pipe sensor 3-6 controls the lifting cylinder 3-5 to rise, and controls the transmission motor 3-4 to make the transmission wheel 3-7 drive the support rod 3-2 to move to the side away from the roller; when the steel pipe is transmitted to a position close to the previous steel pipe, the steel pipe sensor 3-6 controls the lifting cylinder 3-5 to descend, and controls the transmission motor to make the transmission wheel 3-7 drive the support rod 3-2 back to the side close to the roller.

All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
