Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wear-resistant alloy composite pipeline, in particular to a wear-resistant alloy composite pipeline and a manufacturing method thereof. BACKGROUND

[0002] The wear-resistant alloy composite pipeline is a material conveying pipeline commonly used in the power, metallurgy, coal and other industries in the prior art. Most of the pipelines are steel pipes as base pipes combined with high wear-resistant materials on the inner wall. However, the existing wear-resistant alloy composite pipeline is installed with interval type pipe racks for support. However, the inner wall of the pipeline is hollow and does not have any internal support structure. During transportation, the surface of the pipeline may be indented due to collision and extrusion. When installed underground, the settlement of the foundation may cause the pipeline to locally bear excessive shear stress. When installed on the ground, the falling of part of the support may cause a single support to bear stress, resulting in excessive extrusion of the pipeline due to the reaction force, or stress concentration due to the rapid cooling and heating rate of the pipeline, which may cause the pipeline to be indented during use. The indentation not only affects the material conveying, but also causes the pipeline to deform due to the indentation, which may affect the connection sealing and even cause the pipeline to rupture, requiring shutdown for repair.

[0039] As a preferred embodiment in the present embodiment, as shown in Figure 7 、 Figure 10 and Figure 11 , the rotating adjusting mechanism comprises linear sliding grooves 35, three groups of linear sliding grooves 35 are annularly arranged on the side surface of the fixing disc 33, close to the rotating disc 34, and linear sliding blocks 36 are slidably arranged in the linear sliding grooves 35, the end of the connecting rod 37 is fixedly connected to the linear sliding blocks 36, a spiral guide rail 44 is formed on the surface of the rotating disc 34, the connecting rod 37 is movably inserted in the spiral guide rail 44, a support 39 is fixedly connected to the fixing disc 33, a second driving motor 40 is fixedly installed on the support 39, a positioning shaft 41 is rotatably installed in the support 39 through a bearing, the output end of the second driving motor 40 is fixedly connected to the positioning shaft 41, a driving gear 42 is fixedly sleeved on the positioning shaft 41, and the outer wall of the rotating disc 34 is provided with gear teeth 43 which are matched with and meshed with the driving gear 42.

[0040] In the structure, the linear sliding blocks 36 are square, and the inner diameter of the linear sliding grooves 35 is matched with the outer diameter of the linear sliding blocks 36, so that the linear sliding blocks 36 can slide in the linear sliding grooves 35, but cannot be taken out and rotated, thereby ensuring that the angles of the three groups of clamping blocks 38 can always be kept. The spiral guide rail 44 is in the shape of a spiral line, so that when the spiral guide rail 44 rotates, the connecting rod 37 can be driven to translate along the linear sliding grooves 35 through the limiting of the spiral guide rail 44, thereby making the three groups of clamping blocks 38 can be expanded or closed, so as to adapt to supporting rings 2 of different sizes, and at the same time, the outer expansion can support the inner wall of the clamping groove 13, thereby realizing tensioning and supporting, so as to fix the supporting ring 2, and making the supporting ring 2 can be driven to translate in the wear-resistant alloy composite pipeline body 1.

[0041] The center position of the fixed disc 33 is rotatably installed with a rotating column 45 through a bearing, the fixed disc 33 is provided with a driving mechanism, and the outer side of the rotating column 45 is provided with a push rod 53 through an expansion mechanism.

[0042] As a preferred embodiment in the present embodiment, as shown in Figure 6 、 Figure 7 and Figure 11 , the expansion mechanism includes a second guide groove 49, the rotating column 45 is provided with the second guide groove 49, the second guide groove 49 is fixedly installed with an electric push rod 50, and the movable rod end of the electric push rod 50 is fixedly connected with a second guide block 51, the second guide block 51 slides in the second guide groove 49, the second guide block 51 is hingedly connected with three groups of movable hinge rods 52 in an annular array, and the end of the movable hinge rod 52 away from the second guide block 51 is hingedly connected with the push rod 53, the side of the push rod 53 away from the movable hinge rod 52 is hingedly connected with a positioning hinge rod 54, and the end of the positioning hinge rod 54 away from the push rod 53 is hingedly connected with the outer wall of the rotating column 45.

[0043] In the structure, the surface of the rotating column 45 is provided with an opening communicating with the second guide groove 49, and the second guide block 51 is hingedly connected with the movable hinge rod 52 through the opening, the movable hinge rod 52 and the positioning hinge rod 54 are in the same plane, that is, the hinge points are parallel, and the push rod 53 is designed to be out of position with the connecting rod 37, that is, the push rod 53 and the clamping block 38 are not overlapped when they are in the same plane, so that the push rod 53 will not contact the clamping block 38 or the connecting rod 37 when rotating to cause motion interference. The structure is used to drive the second guide block 51 by the electric push rod 50 to drive the push rod 53 to fold close or spread away to adapt to the inner diameter of the support ring 2 of different sizes, on the side of the contact fixing seat 5, and to exert torque on it to make the external thread ring 4 rotate. In this process, since the push rod 53 is a cylinder, that is, its surface has no obvious corners, so it will not cause unnecessary scratching and wear of the fixing seat 5.

[0044] As a preferred embodiment in the present embodiment, as shown in Figure 2 and Figure 6 , one end of the support ring 2 is provided with a clamping groove 13 matched with the clamping block 38, the center column 14 is provided with four groups of movable racks 21 through a manual adjusting assembly, and each group of movable racks 21 is provided with a translation mechanism, one group of movable racks 21 is provided with a vibration mechanism, the fixed disc 33 is fixedly installed with a support 55, and the support 55 is fixedly installed with a camera 56.

[0045] Among them, the outer diameter of the support ring 2 is smaller than the inner diameter of the wear-resistant alloy composite pipeline body 1, so that it can move conveniently in the wear-resistant alloy composite pipeline body 1 and will not cause friction and scratching with the inner wall of the wear-resistant alloy composite pipeline body 1.

[0046] As shown in Figure 3As shown, the connecting threads of the inner threaded groove 3 and the outer threaded ring 4 are self-locking threads, while the linear guide rail 6 is inclined on the fixed seat 5, the connecting column 7 is cylindrical, the inner diameter size of the linear guide rail 6 is matched with the outer diameter size of the connecting column 7, and the connecting column 7 is provided with a limiting block at both ends. The seat sleeve 8 can move on the connecting column 7, but it will not be separated due to the existence of the limiting block. The center column 14 is fixedly connected at the center position of the fixed disc 33, that is, the center column 14, the fixed disc 33, the rotating disc 34 and the rotating column 45 are coaxial.

[0047] As shown in Figure 1 、 Figure 3 、 Figure 4 and Figure 10 , the inner wall of the clamping groove 13 is provided with transverse cylindrical convex strips at equal intervals, and the surface of the clamping block 38 is provided with cylindrical grooves matched with the cylindrical convex strips. When the clamping block 38 is tightly clamped with the clamping groove 13, the supporting ring 2 will be relatively fixed with the fixed disc 33. When the outer threaded ring 4 is rotated by the lever 53, the supporting ring 2 will not rotate, so that the inner threaded groove 3 in the supporting ring 2 can be screwed with the outer threaded ring 4, thereby locking the supporting seat 10.

[0048] The fixed disc 33 is provided with a battery and a controller to supply power to each motor and the camera 56 in the device, and to provide control. The camera 56 is provided with a lighting lamp to illuminate the view angle.

The lighting lamp on the camera 56 provides light source, so that the image captured by the camera 56 can be seen. The camera 56 can observe the movement track and position of the supporting seat 10, the clamping block 38 and the lever 53 in the wear-resistant alloy composite pipe body 1, so as to facilitate the movement of each part.

[0049] As a preferred embodiment in this embodiment, as shown in Figure 2 、 Figure 3 and Figure 4 , six groups of supporting seats 10 are arranged on one side of the supporting ring 2 in a single ring array. The longitudinal section of the supporting seat 10 is arc-shaped, the supporting seat 10 is tightly fitted with the inner wall of the wear-resistant alloy composite pipe body 1, and the side of the supporting seat 10 tightly fitted with the inner wall of the wear-resistant alloy composite pipe body 1 is provided with anti-skid lines.

[0050] The annular array of the six groups of support seats 10 in the structure is beneficial to ensure the support of the inner wall of the wear-resistant alloy composite pipeline body 1. Moreover, the corners of the support seats 10 are arc-shaped, which is used to avoid unnecessary hard scratches when the support seats 10 are attached to the inner wall of the wear-resistant alloy composite pipeline body 1. Meanwhile, the arc-shaped structure can ensure that the support seats 10 can be well attached to the inner wall of the wear-resistant alloy composite pipeline body 1 to implement support. The anti-skid lines on the surface of the support seats 10 are vertically opposite to the axis of the wear-resistant alloy composite pipeline body 1. In this way, the support seats 10 can have good friction when attached to the inner wall of the wear-resistant alloy composite pipeline body 1, thereby achieving the anti-skid effect and avoiding the translation of the support ring 2 in the wear-resistant alloy composite pipeline body 1 due to fluid impact after installation.

[0051] As a preferred embodiment in the present embodiment, as shown in Figure 6 , Figure 8 , the manual adjustment assembly includes a first guide groove 15, the first guide groove 15 is transversely formed in the center column 14, a screw rod 16 is rotatably installed in the first guide groove 15, one end of the screw rod 16 penetrates out of the center column 14 and is fixedly connected with a rotating handle 17, a screw sleeve 18 is threadedly sleeved on the screw rod 16, the outer side of the screw sleeve 18 is fixedly sleeved with a first guide block 19, the first guide block 19 is slidingly arranged in the first guide groove 15, four groups of first hinged frame rods 20 are annularly and hingedly arranged on the first guide block 19, one end of the first hinged frame rod 20 away from the center column 14 is hingedly connected with a movable frame 21, a T-shaped sliding groove 22 is transversely formed in the movable frame 21, a T-shaped sliding block 23 is slidingly arranged in the T-shaped sliding groove 22, a second hinged frame rod 24 is hingedly connected to the T-shaped sliding block 23, and one end of the second hinged frame rod 24 away from the T-shaped sliding block 23 is hingedly connected to the lower end of the center column 14, and the center points of the second hinged frame rod 24 and the first hinged frame rod 20 are rotatably connected.

The structure is used to manually adjust the distance between the four groups of movable frames 21 and the center column 14 by rotating the rotating handle 17, so that the distance of the four groups of movable frames 21 can be adapted to enter the wear-resistant alloy composite pipelines with different diameters.

[0053] As a preferred embodiment in the present embodiment, as shown in Figure 2 , Figure 6 , Figure 8As shown, the translation assembly includes a roller 25, two groups of rollers 25 are symmetrically installed on one side of the movable frame 21 close to the inner wall of the wear-resistant alloy composite pipeline body 1, a brake motor 26 is fixedly installed on the side wall of the movable frame 21, and the output end of the brake motor 26 is fixedly connected with the central shaft of one group of rollers 25.

The brake motor 26 is an electromagnetic power-off brake motor, which is a mature prior art, and its specific structure and principle will not be described here. The rotation of the group of rollers 25 driven by the brake motor 26 can make the device translate in the pipeline. The outer wall of the roller 25 is provided with a rubber ring, and the surface of the rubber ring can be provided with anti-skid lines to ensure that the rubber ring can prevent unnecessary scratching and wear of the inner wall of the wear-resistant alloy composite pipeline body 1 when the device is translated by the rotation of the wear-resistant alloy composite pipeline body 1. In addition, the brake motor 26 is a mature prior art, and its basic principle is to use power-off braking, that is, when powered on, the electromagnetic brake is engaged to allow the rotor to rotate freely, and after power-off, the mechanical brake is engaged by a spring.

[0056] When the vibration mechanism is used, it is preferably close to the side of the pedestrian, that is, when the pipeline is installed underground, the device can be placed in the wear-resistant alloy composite pipeline body 1 before the person walks on the pipeline, so that the vibration mechanism is on the upper side of the pipeline inside, and when the pipeline is installed on the ground, the person walks on the pipeline, so that the vibration mechanism is on both sides of the pipeline inside, so that the vibration source is close to the side of the person, so that the installer can judge the position of the device by vibration, and roughly know the position of the support ring 2, so as to facilitate installation and positioning.

[0059] As a preferred embodiment in the present embodiment, the wear-resistant alloy composite pipeline body 1 is divided into two layers, and the outer layer is formed by hot rolling of a steel plate;

[0060] Then, the inner wall of the base pipe is pretreated by sand blasting, rust removal and oil removal;

[0061] Then, the wear-resistant inner lining layer is formed by surfacing high chromium alloy on the inner wall of the outer layer;

[0062] Finally, the stress is eliminated through heat treatment processing.

[0063] Now the inner and outer layers are combined by an automatic surfacing machine, the pretreatment ensures that the bonding surface is clean and rough, so as to improve the bonding force, and the heat treatment processing not only eliminates the stress, but also improves the metal structure and enhances the toughness of the alloy layer.

[0064] Working principle: in use, first wear-resistant alloy composite pipeline body 1 is laid, then the clamping groove 13 on the support ring 2 is aligned with the three sets of clamping blocks 38, and the lever 53 needs to be inserted into the support ring 2, then the second drive motor 40 is started to drive the positioning shaft 41 to rotate, and the positioning shaft 41 drives each drive gear 42 to rotate, so that the drive gear 42 drives the rotating disc 34 to rotate through the teeth 43, when the rotating disc 34 rotates, the connecting rod 37 is guided by the spiral guide rail 44, so that the connecting rod 37 slides along the straight line sliding groove 35 and expands, so that the three sets of clamping blocks 38 support the clamping groove 13 to fix the support ring 2, then the support ring 2 is put into the wear-resistant alloy composite pipeline body 1;

[0065] Then rotate the handle 17, so that the handle 17 drives the screw rod 16 to rotate, and the screw sleeve 18 drives the first guide block 19 to move transversely along the first guide groove 15 through the screw thread action, so that the first hinged frame rod 20 is hinged and rotated with the second hinged frame rod 24 to fold, and the T-shaped block 23 is driven to translate in the T-shaped groove 22, when the first hinged frame rod 20 and the second hinged frame rod 24 are hinged and folded, four sets of movable frames 21 are expanded, so that the four sets of movable frames 21 on the four sets of movable frames 21 can be expanded to the similar size of the inner wall of the wear-resistant alloy composite pipeline body 1, then the device is provided as a whole and sent into the wear-resistant alloy composite pipeline body 1, and then the handle 17 is rotated, so that the four sets of movable frames 21 on the four sets of movable frames 21 are in contact with the inner wall of the wear-resistant alloy composite pipeline body 1. At the same time, during the process, the rotating head 30 needs to be on one side of the pedestrian, that is, when the person is on the upper side of the wear-resistant alloy composite pipeline body 1, the rotating head 30 is located on the upper side, and when the person is on the two sides of the wear-resistant alloy composite pipeline body 1, that is, the rotating head 30 is located on the two sides, so that the vibration source can be clearly felt in the subsequent process, and the internal state can be observed in real time through the camera 56;

[0066] Subsequently, the device can carry the support ring 2 to translate in the wear-resistant alloy composite pipeline body 1 by driving the roller 25 to rotate by the brake motor 26, while the first drive motor 28 can drive the rotating shaft 29 to rotate at intervals, so that the rotating head 30 drives the impact block 32 to rotate by the return spring 31. When the impact block 32 rotates, it will pull the return spring 31 due to centrifugal force and hit the inner wall of the wear-resistant alloy composite pipeline body 1, thereby generating vibration. Artificially, the position of the device can be roughly understood by touching and listening to the sound from the outside. After moving the support ring 2 to the approximate position in this way, the electric push rod 50 is started to drive the movable rod end of the electric push rod 50 to drive the second guide block 51 to slide along the second guide groove 49, so that the second guide block 51 drives the movable hinged rod 52 to spread the lever 53, so that the three groups of levers 53 can be relatively close to the outer threaded ring 4 and at the side of the fixed seat 5. At the same time, the third motor 47 can drive the driving gear 48 to rotate, the driving gear 48 drives the driven gear 46 to rotate, and the driven gear 46 drives the rotating column 45 to rotate, so that the three groups of levers 53 rotate to adjust their positions, so that the levers 53 can be on the side of the fixed seat 5 after expansion. Finally, the third motor 47 drives the three groups of levers 53 to continue to rotate, and the levers 53 resist the fixed seat 5 to apply a torsional force, so that the outer threaded ring 4 rotates in the inner threaded groove 3 and performs a threaded action, while the fixed seat 5 rotates and drives the connecting column 7 to lift through the linear guide rail 6, so that the connecting column 7 drives the two groups of seat sleeves 8 to move upwards, so that the inclined support frame rod 9 rotates under stress and drives the support seat 10 to adhere to the inner wall of the wear-resistant alloy composite pipeline body 1. With the driving of the third motor 47, the support seat 10 closely adheres to the inner wall of the wear-resistant alloy composite pipeline body 1 to achieve support.

[0067] When the support seats 10 arranged in an annular array on both sides of the support ring 2 support the inner wall of the wear-resistant alloy composite pipeline body 1, the place of the wear-resistant alloy composite pipeline body 1 can be supported. When the local part of the wear-resistant alloy composite pipeline body 1 is subjected to inward stress, the support seat 10 will transmit the force to the support ring 2 through the inclined support frame rod 9 and the connecting block 11, and disperse to each support seat 10, thereby playing a reinforcing role on the place of the wear-resistant alloy composite pipeline body 1, and reducing the possibility of depression at that place.

[0068] Finally, the electric push rod 50 is started to drive the second guide block 51, so that the movable hinged rod 52 pulls the lever 53 to fold, and the second drive motor 40 is started to drive the connecting rod 37 to fold, so that the clamping block 38 leaves the clamping groove 13. After that, the brake motor 26 drives the roller 25 to rotate to move out of the wear-resistant alloy composite pipeline body 1 to the pipe opening.
