Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe production equipment, specifically to a steel pipe transmission noise reduction device and transmission system. Background Technology

[0002] In the steel pipe manufacturing industry, especially in the oil casing production process, noise issues during steel pipe conveying and temporary storage urgently need to be addressed. Taking our company as an example, the oil pipes we produce are 9-13 meters long and 73-340mm in diameter. The common conveying method in the industry is to use three or four sets of parallel inclined platforms to allow the steel pipes to roll naturally. The inclined platforms can also temporarily store several to dozens of steel pipes.

[0003] However, this method has serious drawbacks. The rolling steel pipes frequently collide with the stationary steel pipes temporarily stored on the inclined platform, generating extremely high noise levels, exceeding 120 decibels in tests. This not only causes worker fatigue and reduces work efficiency, but also seriously damages hearing and other health conditions in the long run, increasing labor costs and potential legal risks for the company. Simultaneously, the noise interferes with the normal operation of production equipment, shortening its lifespan. With increasingly stringent environmental regulations, noise pollution from steel pipe production faces enormous regulatory pressure. Therefore, developing a mechanism to effectively reduce steel pipe collision noise is crucial for protecting employee health, improving corporate efficiency, and enhancing industry competitiveness. Utility Model Content

[0004] The purpose of this utility model is to provide a noise reduction device and system for steel pipe transmission. By setting up a noise reduction component consisting of a support frame, a track frame, and a traveling trolley, the traveling trolley controls the movement of the steel pipe and slowly transports the steel pipe to the designated position, avoiding high-speed collisions caused by the natural rolling of the steel pipe. This reduces the possibility of collision noise from the transmission method, thereby effectively reducing noise, improving the working environment, and solving the noise problem caused by collisions during transmission and temporary storage in steel pipe production.

[0005] This utility model is achieved through the following technical solution:

[0006] A noise reduction device for transporting steel pipes includes a noise reduction component for transporting steel pipes, the noise reduction component including a support frame, a track frame and a traveling trolley;

[0007] The track frame is inclinedly disposed at the upper end of the support frame, and a track groove is formed in the middle of the track frame to accommodate the traveling trolley. The traveling trolley reciprocates along the track groove through a drive assembly and slowly transports the steel pipe to the designated position.

[0008] In this solution, the traveling trolley conveys steel pipes by reciprocating along the track groove through the drive component, which changes the traditional natural rolling conveying method. The drive component realizes active control of the trolley's movement, which can slowly convey the steel pipes to the designated position, improving the accuracy and controllability of the transmission. Compared with the traditional method of relying on gravity to roll naturally, which leads to uncontrollable collisions of steel pipes, this working method changes from passive transmission to active and precise delivery, avoiding high-speed collisions caused by the natural rolling of steel pipes and reducing the possibility of noise generation from the source.

[0009] As an optimized solution for the steel pipe conveying noise reduction device, the steel pipe conveying noise reduction device further includes a conveying rack. At least one set of the conveying rack is provided on one or both sides of the noise reduction component, and the conveying rack is inclined at the same angle as the track frame.

[0010] In this solution, the conveyor rack shares the load-bearing task of the steel pipe, reducing the pressure on the track frame and traveling trolley in the noise reduction component, which helps to extend the service life of the device, ensures the stable operation of the entire conveyor noise reduction system, and enhances the applicability and reliability of the device in actual production environments.

[0011] As an optimized solution for the noise reduction device of steel pipe conveying, a baffle plate is provided at the end of the conveying rack.

[0012] In this solution, a baffle plate is installed at the end of the conveyor rack, effectively preventing the steel pipes from slipping off the rack due to inertia or other external forces. This avoids collisions and noise caused by slipping, and also prevents potential safety accidents caused by falling steel pipes, ensuring production safety. Simultaneously, it ensures the steel pipes can be stably stored on the conveyor rack, facilitating accurate grabbing and transport of the steel pipes by the subsequent traveling trolley.

[0013] As an optimized solution for the noise reduction device for steel pipe transmission, the traveling trolley includes a cylinder and a pipe-stopping rod;

[0014] The cylinder is connected to the drive assembly and moves synchronously with the drive assembly. The pipe baffle is connected to the output end of the cylinder. When the pipe baffle slowly transports the steel pipe to the designated position, the pipe baffle retracts to below the track groove, so that the steel pipe stops at the designated position. When the pipe baffle returns to the initial position, the pipe baffle extends and resets.

[0015] In this design, the cylinder moves synchronously with the drive assembly, ensuring that the pipe-stopping bar accurately contacts and pushes the steel pipe. Upon reaching the designated position, the pipe-stopping bar retracts, precisely stopping the steel pipe and preventing it from rolling or colliding. This significantly improves the accuracy of the transmission. This precise control also avoids violent impacts caused by the steel pipe accelerating due to natural rolling, effectively reducing collision noise. Simultaneously, the pipe-stopping bar extends and resets when returning to its initial position, preparing for the next steel pipe delivery.

[0016] As an optimized solution for the noise reduction device for steel pipe transmission, the drive assembly includes a belt driven pulley, a belt, and a servo motor;

[0017] The belt driven pulley is connected around the support frame, so that the belt is tensioned in the track groove. The cylinder is connected to the belt, and the belt reciprocates along the track groove driven by the servo motor.

[0018] In this solution, the servo motor serves as the power source. Its stable and adjustable power output ensures that the belt, in conjunction with the belt driven pulley, can drive the cylinder connected to the belt and the traveling trolley to move smoothly back and forth along the track groove, thus achieving reliable transmission of steel pipes. Furthermore, by controlling the servo motor, the running speed of the trolley can be adjusted according to actual production needs, thereby precisely controlling the conveying rhythm of the steel pipes and avoiding violent collisions between steel pipes due to excessive speed.

[0019] As an optimized solution for the steel pipe transmission noise reduction device, a fifth sensor for detecting the position of the traveling trolley is provided at the tail end of the track groove. The fifth sensor is electrically connected to the cylinder and the drive assembly respectively.

[0020] In this scheme, the fifth sensor can monitor the steel pipe reaching the end of the track groove in real time. Once the steel pipe is detected, it immediately sends a signal to the cylinder, causing the cylinder to react quickly and control the retraction of the pipe-stopping rod to ensure that the steel pipe can be accurately stopped at the designated position, avoiding collisions caused by the steel pipe exceeding the designated position and improving the accuracy of transmission.

[0021] As an optimized solution for the steel pipe transmission noise reduction device, a second sensor for detecting the position of the steel pipe is provided at the rear of the traveling trolley. The second sensor is electrically connected to the cylinder and the drive assembly respectively.

[0022] In this solution, the second sensor monitors the position of the steel pipe at the rear of the trolley in real time, providing the device with accurate position information. When the steel pipe is detected to be in a specific position, it can quickly transmit the signal to the cylinder and drive assembly. For the cylinder, the state of the pipe-stopping bar can be adjusted in a timely manner according to the signal. For example, when the steel pipe approaches other steel pipes or a designated parking point, the pipe-stopping bar can be controlled to retract or extend to ensure that the steel pipe is accurately docked and parked, avoiding collisions. For the drive assembly, the movement state of the trolley can be adjusted according to the position of the steel pipe, realizing fine control of the trolley's movement and making the steel pipe transmission process smoother and more efficient.

[0023] As an optimized solution for the noise reduction device for steel pipe transmission, a fourth sensor, a third sensor, and a first sensor are sequentially installed at the initial position.

[0024] The fourth sensor, the third sensor, and the first sensor are all electrically connected to the drive assembly.

[0025] In this solution, these sensors can accurately detect whether the steel pipe has reached the initial position. Once the steel pipe is detected, the sensor quickly transmits the signal to the drive assembly to ensure that the drive assembly starts in time and drives the trolley to start working. This achieves precise triggering of the steel pipe transmission process. This precise control of the trolley's movement can effectively reduce collisions between steel pipes and between steel pipes and device components, further reducing noise generation.

[0026] A steel pipe transport system includes a steel pipe transport noise reduction device, and multiple sets of the steel pipe transport noise reduction devices are arranged in a parallel and spaced array.

[0027] In this solution, multiple sets of devices work in parallel, which can transmit a larger number of steel pipes at the same time compared to a single device, greatly improving the overall transmission efficiency and meeting the needs of rapid and large-scale steel pipe transmission in large-scale production scenarios. In addition, each set of devices has a noise reduction function, and the collaborative work of multiple sets can reduce the collision noise during the steel pipe transmission process over a wider range.

[0028] Furthermore, the system also includes a PLC control component, which is electrically connected to the fifth sensor, the fourth sensor, the third sensor, the second sensor, and the first sensor.

[0029] In this solution, the PLC control component precisely adjusts the servo motor speed, enabling the traveling trolley to move at an appropriate speed. Simultaneously, it controls the extension and retraction of the cylinders in a timely manner, driving the pipe-stopping rod to accurately complete actions such as pushing and parking the steel pipes. This not only achieves full automation of the steel pipe transport process, reducing manual intervention and improving production efficiency, but also avoids steel pipe collisions through precise control, effectively reducing noise and enhancing the stability and reliability of the system operation.

[0030] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0031] This invention utilizes a noise reduction component consisting of a support frame, a track frame, and a traveling trolley. The traveling trolley, driven by a drive assembly, slowly transports the steel pipe to the designated position, avoiding high-speed collisions caused by the pipe's natural rolling. Simultaneously, cylinders and a pipe-stopping bar on the traveling trolley precisely control the pipe's movement. Upon reaching the designated position, the pipe-stopping bar retracts, allowing the pipe to stop smoothly. This reduces collisions between pipes and between the pipe and other components, significantly lowering noise levels and creating a better working environment for workers, effectively protecting their hearing and other health.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0042] Example 1

[0043] This embodiment 1 provides a noise reduction device for steel pipe transmission, such as Figures 1-6As shown, the device includes a noise reduction assembly 2 for transporting steel pipes. The noise reduction assembly 2 includes a support frame 8, a track frame 5, and a traveling trolley 11. The support frame 8 serves to support and stabilize the entire device. The track frame 5 is inclinedly set on the upper end of the support frame 8. The track groove in the middle of the track frame 5 provides a running track for the traveling trolley 11. The inclined design of the track frame 5 is conducive to the transmission of steel pipes under gravity assistance. The traveling trolley 11 moves in the track groove through a drive assembly and is responsible for transporting steel pipes 1. By controlling the movement of steel pipes 1 using the traveling trolley 11, the steel pipes 1 are slowly transported to the designated position, avoiding high-speed collisions caused by the natural rolling of steel pipes 1, thus reducing the possibility of collision noise from the transmission method.

[0044] Please refer to Figure 1 As shown, a set of conveyor racks 3 are set on each side of the noise reduction component 2. Of course, multiple sets can be set according to the actual requirements of the steel pipe 1. The conveyor racks 3 are tilted synchronously with the track frame 5 to share the load-bearing task of the steel pipe 1, reducing the pressure on the track frame 5 and the traveling trolley 11. Furthermore, the ends of the conveyor racks 3 are all connected to baffle plates 4, which effectively prevent the steel pipe 1 from slipping off the conveyor racks 3 due to inertia or other external forces.

[0045] Please refer to Figures 2-6 As shown, the drive assembly includes a belt-driven pulley 6, a belt 7, and a servo motor 17. The belt-driven pulley 6 is connected to the support frame 8 around its perimeter, causing the belt 7 to be tensioned in the track groove. The traveling trolley 11 is connected to the belt 7, and the belt 7 reciprocates along the track groove driven by the servo motor 17. Specifically, the traveling trolley 11 includes a cylinder 9 and a pipe-stopping rod 13. The cylinder 9 is connected to the belt 7 and moves synchronously with the belt 7. The pipe-stopping rod 13 is connected to the output end of the cylinder 9. When the pipe-stopping rod 13 slowly transports the steel pipe 1 to the designated position, the pipe-stopping rod 13 retracts to the bottom of the track groove, stopping the steel pipe at the designated position. When the pipe-stopping rod 13 returns to the initial position, the pipe-stopping rod extends and resets, preparing for the next steel pipe 1.

[0046] Please also refer to Figures 2-6 As shown, a fifth sensor 16 for detecting the position of the traveling trolley 11 is connected to the tail end of the track groove. The fifth sensor 16 is located at the designated position at the tail end of the track groove for storing the first steel pipe 1, and is electrically connected to the cylinder 9 and the drive assembly respectively. In use, the fifth sensor 16 can monitor the extreme position of the traveling trolley 11. Once the traveling trolley 11 is detected, it immediately sends a signal to the drive assembly to stop the traveling trolley 11, and at the same time sends a signal to the cylinder 9 to make the cylinder 9 react quickly and control the pipe-stopping rod 13 to retract, ensuring that the steel pipe 1 can be accurately stopped at the designated position.

[0047] A second sensor 12 for detecting the position of the steel pipe 1 is also connected to the rear of the traveling trolley 11. The second sensor 12 is electrically connected to the cylinder 9 and the drive assembly. The second sensor 12 monitors the position of the steel pipe 1 that has been parked at the rear of the trolley in real time, providing the device with accurate position information. When it detects that a steel pipe 1 has been parked at the parking position in front, it can quickly transmit the signal to the cylinder 9 and the drive assembly. When it gets close to the adjacent steel pipe 1, the traveling trolley 11 stops moving forward. The cylinder 9 adjusts the state of the pipe-stopping rod 13 in time according to the signal. When the transmitted steel pipe 1 approaches the parking point, it controls the pipe-stopping rod 13 to retract, ensuring that the steel pipe is accurately connected and parked, and avoiding collision.

[0048] At the initial position of the track groove, a fourth sensor 15, a third sensor 14, and a first sensor 10 are connected in sequence. The fourth sensor 15, the third sensor 14, and the first sensor 10 are all electrically connected to the drive assembly. The fourth sensor 15 can detect whether there is a steel pipe 1 from the previous process at the initial position. When the traveling trolley 11 delivers the steel pipe 1 to the designated position and returns to the initial position, when it passes the first sensor 10, the first sensor 10 sends a deceleration signal to the traveling trolley 11, thereby controlling the servo motor 17 to decelerate. The traveling trolley 11 reduces its speed and moves to the third sensor 14. The third sensor 14 sends a stop signal to the traveling trolley 11. At this time, the cylinder 9 raises the pipe-stopping bar 13 and continues the next cycle.

[0049] Example 2

[0050] This embodiment 2 provides a steel pipe transmission system based on embodiment 1, such as... Figure 1 As shown, the system includes a PLC control component and a steel pipe conveying noise reduction device. Multiple sets of steel pipe conveying noise reduction devices are arranged in a parallel, spaced array. The PLC control component is electrically connected to the fifth sensor 16, the fourth sensor 15, the third sensor 14, the second sensor 12, and the first sensor 10. The PLC control component precisely adjusts the speed of the servo motor 17 to make the traveling trolley 11 move at a suitable speed. At the same time, it controls the extension and retraction of the cylinder 9 in a timely manner, driving the pipe-stopping rod 13 to accurately complete actions such as pushing and parking the steel pipe 1. This realizes the full automation of the steel pipe conveying process, reduces manual intervention, and improves production efficiency.

[0051] The specific usage process of the above embodiments is as follows:

[0052] The previous station flips the steel pipe 1 to the initial position. At this time, the fourth sensor 15 at the initial position detects the steel pipe 1 and immediately transmits the signal to the PLC control component. After receiving the signal, the PLC control component confirms that there is a steel pipe 1 to be transmitted and prepares for the start of the subsequent transmission process.

[0053] Based on the received signal, the PLC control component starts the servo motor 17 in the drive component. The servo motor 17 drives the belt driven pulley 6 to rotate, causing the belt 7 to move in the track groove. This, in turn, drives the cylinder 9 connected to the belt and the traveling trolley 11 to move slowly forward along the track groove. The moving speed of the traveling trolley 11 is preset in the PLC control component according to production requirements. It is generally set to a speed that ensures both transmission efficiency and smooth transmission of the steel pipe, avoiding collisions.

[0054] When the steel pipe 1 moves with the trolley to the sensing area of ​​the fifth sensor 16, the fifth sensor 16 sends a signal to the PLC control component. The PLC control component issues a command to stop the traveling trolley 11 and retract the cylinder 9 at the bottom of the traveling trolley 11. This causes the pipe-stopping rod 13 connected to the output end of the cylinder 9 to move downwards until the pipe-stopping rod 13 retracts below the track groove. At this point, the steel pipe 1 will gently touch the baffle plate 4 of the conveyor rack 3. Due to the precise control of the pipe-stopping rod 13, the steel pipe 1 avoids violently impacting the baffle plate 4 due to acceleration generated by natural rolling, thereby effectively reducing noise.

[0055] After the guide bar 13 retracts into position, it quickly moves backward to return to its initial position. Simultaneously, the traveling trolley 11 continues to move backward. When the first sensor 10 detects the traveling trolley 11, it transmits a signal to the PLC control unit. The PLC control unit controls the drive unit to reduce the traveling speed of the trolley 11 until it stops at the position of the third sensor 14, ensuring the accuracy and stability of the trolley's movement.

[0056] After the trolley reaches the position of the third sensor 14, the PLC control component controls the cylinder 9 to lift the pipe-stopping rod 13. The magnetic switch installed on the cylinder 9 will send a signal to the PLC control component indicating that the pipe-stopping rod 13 has been lifted to the correct position. At the same time, the PLC control component sends a "pipe-flipping permission signal" to the previous station, notifying it that it can proceed with the flipping operation of the next steel pipe 1.

[0057] After receiving the pipe-flipping instruction, the previous workstation flips the new steel pipe to the position of the fourth sensor 15. The fourth sensor 15 detects the steel pipe 1 again, and the PLC control component controls the servo motor 17 to drive the traveling trolley 11 to move slowly forward on the guide rail. When the second sensor 12 on the traveling trolley 11 senses the steel pipe 1 that is already stationary on the transfer rack 3, the traveling trolley 11 stops moving forward.

[0058] After the traveling trolley 11 stops, the PLC control unit controls the cylinder 9 to retract, causing the pipe-stopping bar 13 to retract as well. This allows the newly delivered steel pipe 1 to gently touch the existing steel pipe 1. This prevents the steel pipe 1 from rolling and accelerating, which would generate noise. After retracting, the pipe-stopping bar 13 quickly returns to the position of the third sensor 14, ready for the next action cycle.

[0059] The above actions are repeated continuously. When the steel pipes 1 accumulate to the position of the first sensor 10 on the conveyor rack 3, the first sensor 10 transmits a signal to the PLC control component. The PLC control component determines that the conveyor rack 3 is full and automatically controls the entire workflow to pause. The new work cycle begins only after the next process has transported the steel pipes away.

[0060] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
