Description

Technical Field

[0001] The invention belongs to the technical field of conveyor rollers for seamless pipe production, and particularly relates to conveyor rollers for seamless pipe production. Background Art

[0002] During the production of seamless pipes, multiple sets of conveyor rollers are required to convey them to multiple processing steps so that they can finally form seamless pipes. After the tube blank is heated, it needs to be conveyed to the punching step. Therefore, during the processing of seamless pipes, the conveyor rollers need to be in contact with the high-temperature tube blank for a long time. At this time, the conveyor rollers are prone to long-term contact with the high-temperature tube blank, which can easily cause their strength to degrade, thereby increasing the loss of the conveyor rollers and reducing their service life.

[0003] In the prior art, cooling water pipes are mainly installed in the conveyor rollers to allow the conveyor rollers to exchange heat from the inside, thereby achieving a cooling effect and preventing the conveyor rollers from overheating and increasing their losses. However, when the cooling pipes are in use, the water flow rate is fixed during cooling, and the water discharge speed during cooling is also fixed. At this time, under long-term conveying work, although the conveyor rollers can be cooled by water, the temperature gradually increases and the cooling efficiency of the water flow is fixed, which easily leads to the temperature of the conveyor rollers increasing at a faster rate than the cooling rate. At this time, the temperature of the conveyor rollers continues to rise, which increases the losses of the conveyor rollers and affects their service life. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to provide a conveyor roller for seamless pipe production, which can solve the problem that the temperature of the conveyor roller continues to rise, causing increased wear of the conveyor roller and affecting its service life.

[0005] In order to solve the above problems, the present invention provides a conveyor roller for seamless pipe production, comprising: a roller body, wherein an inner groove is formed inside the roller body, through holes are formed on both sides of the roller body, both through holes are connected to the inner groove, and a water inlet pipe and a water outlet pipe are rotatably connected to the two through holes;

[0006] The two opposite side walls of the inner tank are fixedly connected with guide covers, and a water inlet control mechanism is provided in the guide cover at the water outlet position to control the water pressure of the inlet water;

[0007] A drainage mechanism is provided between the two guide covers, and the drainage mechanism is used to control the path of the water flow;

[0008] A flow control component is also provided between the two guide covers for controlling the flow of water.

[0009] Furthermore, the water inlet control mechanism includes a control spring, which is fixedly installed at the center of the corresponding guide cover. The end of the control spring is fixedly connected to a sealing plug, and the end of the sealing plug extends into the water inlet pipe, and the outer peripheral side is in contact with the inner peripheral side of the water inlet pipe.

[0010] Furthermore, one end of the sealing plug away from the water inlet pipe is fixedly connected to a limiting rod, and the end of the limiting rod passes through the center position of the corresponding side of the guide cover and is slidably connected to the guide cover.

[0011] Furthermore, the drainage mechanism includes a pipe column, which is fixedly connected between the two guide covers, and a gap is left between the outer peripheral side of the pipe column and the inner peripheral side of the inner groove. A number of water inlet holes are opened on the side of the guide cover near the water inlet pipe, and a drainage groove is opened on the inner peripheral edge of the guide cover near the water outlet pipe.

[0012] Furthermore, a shielding ring is fixedly connected to the inner wall of the guide cover close to the water inlet pipe, the side of the shielding ring fits with the side wall corresponding to the inner groove, and the inner peripheral side wall of the shielding ring is located at the corresponding edge of the water inlet.

[0013] Furthermore, the flow control component includes a control rod, which is fixedly connected to the side of the corresponding guide cover. A sealing rod is sleeved on the control rod, and the end of the sealing rod extends into the corresponding water inlet hole. A sealing spring is also fixedly connected between the sealing rod and the corresponding guide cover.

[0014] Furthermore, the blocking rod is arranged at an end of the water inlet hole in an inclined manner, and the inclined end of the blocking rod is in contact with the outer edge of the corresponding water inlet hole.

[0015] Furthermore, the outer circumferences of the water inlet pipe and the water outlet pipe are rotatably connected to pulleys, and the sides of the pulleys are fixedly connected to the corresponding sides of the roller body.

[0016] Furthermore, the drainage groove is located at the inner peripheral edge of the inner groove, a gap is left between the water inlet and the inner peripheral side of the inner groove, and the outer peripheral side of the guide cover is fixedly connected to the inner peripheral side of the inner groove.

[0017] In summary, the present invention includes at least one of the following beneficial technical effects:

[0018] 1. The conveyor roller for seamless pipe production can control the water flow rate and conveying efficiency according to the temperature of the roller itself during use, so that the low-temperature water can quickly cool down the roller and exchange heat. This prevents the water temperature from rising too quickly after it rises, affecting the subsequent conveying water temperature, and thus affecting the cooling of the roller, causing the roller to be affected by temperature and increase wear.

[0019] 2. The conveyor roller used in seamless pipe production has a gap between the water inlet and the inner circumference of the inner groove to prevent the water from directly scouring the inner circumference of the inner groove due to centrifugal force, making it difficult to quickly pass the water through the water inlet and then enter the middle of the inner groove to perform heat exchange on the roller body;

[0020] 3. The conveyor roller for seamless pipe production has a drainage groove located on the inner circumference of the inner groove, and the drainage groove is expanded near the middle of the inner groove. This allows water to flow through the inner groove and heat the roller body before it can be discharged from the drainage groove, preventing water from being directly discharged without heat exchange.

[0021] 4. The conveyor roller used in seamless pipe production has a limiting rod fixedly connected to the side of the sealing plug away from the water inlet pipe. The limiting rod is used to limit the control spring to prevent the control spring from being affected by the rotation of the roller body, causing the control spring to shake, which in turn drives the sealing plug to shake. In turn, the side of the sealing plug will cause it to contact the end of the water inlet pipe, making it difficult for the sealing plug to control the water flow pressure, affecting the subsequent cooling of the roller body and flow control work;

[0022] 5. In the drainage mechanism of the conveyor roller used in the production of seamless pipes, the pipe column is used to reduce the volume of water in the inner groove, so that the water flow can be quickly filled and the water can contact the circumferential side of the inner groove, thereby quickly exchanging heat inside the roller body. At the same time, the water flows into the middle of the inner groove from the water inlet, exchanges heat with the inner wall of the inner groove, and is discharged from the drainage groove to achieve cooling.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0035] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0036] See also Figures 1-8As shown, according to embodiment 1 of the present invention, a conveyor roller for seamless pipe production is provided, comprising: a roller body 1, wherein an inner groove 2 is formed inside the roller body 1, and through holes 3 are formed on both sides of the roller body 1, both through holes 3 are connected to the inner groove 2, and a water inlet pipe 4 and a water outlet pipe 5 are rotatably connected to the two through holes 3 respectively;

[0037] A guide cover 6 is fixedly connected to the two opposite side walls of the inner tank 2. A water inlet control mechanism 7 is provided in the guide cover 6 at the position of the water outlet pipe 5 for controlling the water pressure of the inlet water.

[0038] A drainage mechanism 8 is provided between the two guide covers 6, and the drainage mechanism 8 is used to control the path of the water flow;

[0039] A flow control component 9 is also provided between the two guide covers 6 for controlling the flow of water;

[0040] The outer circumferences of the water inlet pipe 4 and the water outlet pipe 5 are both rotatably connected to pulleys 20 , and the sides of the pulleys 20 are fixedly connected to the corresponding sides of the roller body 1 .

[0041] In this embodiment, reference Figure 1 , pulleys 20 are fixedly connected to both sides of the roller body 1, and a gap is left between the water inlet pipe 4 and the water outlet pipe 5 corresponding to the pulleys 20. The roller body 1 is driven by the pulley 20. In addition, an external water pump is used to connect the water inlet pipe 4, and the external pipeline is connected to the water outlet pipe;

[0042] refer to Figure 3 , the guide cover 6 is used to reinforce the inner wall of the inner tank 2, and use the guide tank to transport the water flow, the through hole 3 is used to install the corresponding water inlet pipe 4 and water outlet pipe 5, and the water outlet pipe 5 and the water inlet pipe are in a rotating sealed state when they are in the corresponding through hole 3;

[0043] refer to Figure 3 When the roller body 1 is driven, water is pumped by a water pump and injected into the water inlet pipe 4, so that the water can pass through the position of the water inlet control mechanism 7. This mechanism can only deliver water to the inner tank 2 after the water pressure reaches a certain pressure, so as to avoid the water pressure being too low, which makes it difficult for the water to overcome the centrifugal force of the roller body 1, thereby reducing the flow rate and flow rate of the water;

[0044] refer to Figure 3 Then the water will pass through the drainage mechanism 8, which is used to guide the flow of water so that the water can fully fit with the peripheral wall of the inner groove 2 and the inside of the roller body 1, and take away the heat after the roller body 1 contacts the heated tube blank, so as to fully cool the roller body 1;

[0045] refer to Figure 3The water flow will pass through the flow control component 9, which will block the water flow path in the initial state, allowing the water to be transported at a normal flow rate in the initial state. Then, as the temperature of the roller body 1 increases, the flow control component 9 will open the water flow path, allowing the water to flow completely, thereby increasing the water flow rate and thus increasing the flow rate, which can take away the heat from the roller body 1 more quickly.

[0046] In a further preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, the water inlet control mechanism 7 includes a control spring 10, which is fixedly installed at the center of the corresponding guide cover 6. The end of the control spring 10 is fixedly connected to a sealing plug 11, and the end of the sealing plug 11 extends into the water inlet pipe 4, and the outer peripheral side is in contact with the inner peripheral side of the water inlet pipe 4.

[0047] In this embodiment, reference Figure 3 and Figure 4 When the water pump injects water into the water inlet pipe 4, it will flush the sealing plug 11, and the sealing plug 11 is supported by the control spring 10. At this time, when the force of the water pressure flushing is greater than the support force of the spring, the sealing plug 11 can be pushed to move, so that the water flow needs a certain impact force to enter the inner groove 2 of the roller body 1, so as to avoid the water pressure being too low, which leads to the water flow speed being too slow, resulting in the water flow staying in the inner groove 2 for too long, causing excessive evaporation of water vapor, resulting in excessive pressure inside the inner groove 2, and then other internal components are damaged due to high pressure, affecting subsequent use. At the same time, it ensures that the water flow can quickly exchange heat at the high temperature of the roller body 1 when in use at a normal flow rate, thereby improving the cooling efficiency.

[0048] In a further preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, the end of the sealing plug 11 away from the water inlet pipe 4 is fixedly connected to a limiting rod 12, and the end of the limiting rod 12 passes through the center position of the corresponding side of the guide cover 6 and is slidably connected to the guide cover 6.

[0049] In this embodiment, reference Figure 3 and Figure 4 A limiting rod 12 is fixedly connected to the side of the sealing plug 11 away from the water inlet pipe 4. The limiting rod 12 is used to limit the control spring 10 to prevent the control spring 10 from being affected by the rotation of the roller body 1, causing the control spring 10 to shake, and then driving the sealing plug to shake, which in turn causes the side of the sealing plug to contact the end of the water inlet pipe 4, making it difficult for the sealing plug 11 to control the water pressure, affecting the subsequent cooling of the roller body 1 and flow control work.

[0050] In a further preferred embodiment of the present invention, Figure 3 and Figure 4As shown, the drainage mechanism 8 includes a pipe column 13, which is fixedly connected between the two guide covers 6, and a gap is left between the outer peripheral side of the pipe column 13 and the inner peripheral side of the inner groove 2. A number of water inlet holes 14 are opened on the side of the guide cover 6 near the water inlet pipe 4, and a drainage groove 15 is opened on the inner peripheral edge of the guide cover 6 near the water outlet pipe 5.

[0051] In this embodiment, reference Figure 3 and Figure 4 In the drainage mechanism 8, the pipe column 13 is used to reduce the volume of water in the inner tank 2, so that the water flow can be quickly filled and the water can contact the circumferential side of the inner tank 2, thereby quickly exchanging heat inside the roller body 1. At the same time, the water flows into the middle of the inner tank 2 from the position of the water inlet hole 14, and after exchanging heat with the inner wall of the inner tank 2, it is discharged from the position of the drainage groove 15, thereby achieving the cooling work.

[0052] In a further preferred embodiment of the present invention, Figure 4 As shown, a shielding ring 16 is fixedly connected to the inner wall of the guide cover 6 near the water inlet pipe 4, the side of the shielding ring 16 is in contact with the corresponding side wall of the inner groove 2, and the inner peripheral side wall of the shielding ring 16 is located at the corresponding edge of the water inlet.

[0053] In this embodiment, reference Figure 4 A blocking ring 16 is fixedly connected to the inner wall of the corresponding guide cover 6. The blocking ring 16 is used to block the water flow to prevent the water flow from being pushed to the circumferential side of the inner tank 2 due to centrifugal force, making it difficult for the water flow to directly enter the inner tank 2 from the position of the water inlet hole 14 for heat exchange in the first time;

[0054] In addition, the inner circumference of the shielding ring 16 is tilted and tilted toward the water inlet 14, so that the water flow can directly enter the water inlet 14 along the tilt direction of the shielding ring 16, reducing the energy consumption during water transportation and improving the flow efficiency of the water flow.

[0055] In a further preferred embodiment of the present invention, Figure 4 As shown, the flow control component 9 includes a control rod 17, which is fixedly connected to the side of the corresponding guide cover 6. A sealing rod 18 is sleeved on the control rod 17, and the end of the sealing rod 18 extends into the corresponding water inlet 14. A sealing spring 19 is also fixedly connected between the sealing rod 18 and the corresponding guide cover 6.

[0056] In this embodiment, reference Figure 4When water flows through the water inlet 14, it will flush the blocking rod 18, and the blocking rod 18 will slide on the control rod 17. A movable position is reserved inside the blocking rod 18 sleeved on the control rod 17 to avoid blocking the water inlet 14. In addition, the blocking spring 19 is a thermal spring. At the initial temperature, it is in the longest extended state, and the water inlet 14 is blocked at this time.

[0057] When the temperature of the roller body 1 increases, (a corresponding heat-conducting rod is fixedly connected to the outer peripheral side of the sealing spring 19, and the heat-conducting rod can be made of copper or silver), the heat absorbed by the roller body 1 is introduced to the sealing spring 19. The temperature of the sealing spring 19 increases and it will be in a contracted state, thereby reducing the resistance during water flushing. Subsequently, the water flow expands, allowing the water flow to quickly enter the inner groove 2, cooling the roller body 1, and improving the water flow rate and water heat exchange efficiency.

[0058] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, the blocking rod 18 is located at one end of the water inlet hole 14 and is tilted, and the tilted end of the blocking rod 18 is in contact with the outer edge of the corresponding water inlet hole 14 .

[0059] In this embodiment, reference Figure 4 and Figure 5 , so that the end of the blocking rod 18 is set at an angle, so that when the blocking rod 18 is opened in the initial state, the space for water to flow out is small, thereby limiting the flow efficiency and water flow of the water. After the temperature rises, when the blocking rod 18 is completely pulled out of the water inlet 14, the water flow is unobstructed. At this time, the water flow can quickly enter the inner groove 2, thereby quickly filling the inner groove 2 and being discharged from the position of the drainage groove 15, which can quickly perform heat exchange and cooling on the roller body 1.

[0060] In a further preferred embodiment of the present invention, Figure 4-Figure 8 As shown, the drainage groove 15 is located at the inner peripheral edge of the inner tank 2, a gap is left between the water inlet 14 and the inner peripheral side of the inner tank 2, and the outer peripheral side of the guide cover 6 is fixedly connected to the inner peripheral side of the inner tank 2.

[0061] In this embodiment, reference Figure 4-Figure 8 A gap is left between the water inlet hole 14 and the inner circumference of the inner tank 2 to prevent the water from directly washing the inner circumference of the inner tank 2 due to centrifugal force, making it difficult to quickly pass the water through the water inlet groove and then enter the middle of the inner tank 2 to perform heat exchange on the roller body 1;

[0062] The drainage groove 15 is located on the inner circumference of the inner groove 2, and the position of the drainage groove 15 near the middle of the inner groove 2 is expanded, so that when water flows, it fills the inner groove 2 and performs heat exchange on the roller body 1 before it is discharged from the drainage groove 15, avoiding the water being directly discharged without heat exchange.

[0063] The outer circumference of the guide cover 6 is directly fixedly connected to the inner circumference of the inner groove 2. At this time, the guide cover 6 can be used to further support the roller body 1, thereby improving the stability of the roller body 1 during use and avoiding the reduction of its own strength due to the internal opening.

[0064] Working principle: When the water pump injects water into the water inlet pipe 4, it will flush the sealing plug 11, which is supported by the control spring 10. At this time, when the force of the water pressure flushing is greater than the support force of the spring, the sealing plug 11 can be pushed to move, so that the water flow needs a certain impact force to enter the inner groove 2 of the roller body 1;

[0065] The pipe column 13 is used to reduce the volume of water in the inner tank 2 so that the water flow can be quickly filled and the water can contact the circumferential side of the inner tank 2, thereby quickly exchanging heat with the inside of the roller body 1. At the same time, the water flows into the middle position of the inner tank 2 from the position of the water inlet 14, exchanges heat with the inner wall of the inner tank 2, and is discharged from the position of the drainage groove 15; in addition, a blocking ring 16 is fixedly connected to the inner wall of the corresponding guide cover 6, and the blocking ring 16 is used to block the water flow to prevent the water flow from being pushed to the position of the circumferential side of the inner tank 2 due to centrifugal force, which makes it difficult for the water flow to directly enter the inner tank 2 from the position of the water inlet 14 for heat exchange in the first time; and the inner circumference of the blocking ring 16 is inclined and inclined in the direction of the water inlet 14, so that the water flow can directly enter the water inlet 14 along the inclined direction of the blocking ring 16, thereby reducing the energy consumption during water transportation and improving the flow efficiency of the water flow.

[0066] When water flows through the water inlet 14, it will flush the blocking rod 18, and the blocking rod 18 will slide on the control rod 17. A movable position is reserved inside the blocking rod 18 sleeved on the control rod 17 to avoid blocking the water inlet 14. In addition, the blocking spring 19 is a thermal spring. At the initial temperature, it is in the longest extended state, at which time the water inlet 14 is blocked.

[0067] When the temperature of the roller body 1 increases, (a corresponding heat-conducting rod is fixedly connected to the outer circumference of the blocking spring 19, and the heat-conducting rod can be made of copper or silver), the heat absorbed by the roller body 1 is introduced to the blocking spring 19. The blocking spring 19 will be in a contracted state when the temperature increases, thereby reducing the resistance of the water flow during flushing. Subsequently, the water flow expands, allowing the water flow to quickly enter the inner tank 2, cooling the roller body 1, and improving the water flow rate and water heat exchange efficiency.

[0068] Finally, the end of the blocking rod 18 is set at an angle, so that when the blocking rod 18 is opened in the initial state, the space for water to flow out is small, thereby limiting the flow efficiency and water flow of the water. After the temperature rises, when the blocking rod 18 is completely pulled out of the water inlet 14, the water flow is unobstructed. At this time, the water flow can quickly enter the inner groove 2, thereby quickly filling the inner groove 2 and being discharged from the drainage groove 15, which can quickly perform heat exchange and cooling on the roller body 1.

[0069] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0070] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art may make various improvements and variations without departing from the technical principles of the present invention, and such improvements and variations shall also be considered within the scope of protection of the present invention.
