Description

Technical Field

[0001] This invention belongs to the field of geotechnical engineering technology, and specifically relates to a fiber orientation device for ultra-high performance concrete. Background Technology

[0002] In the field of building materials, concrete is the most widely used, and its performance directly affects the safety and durability of building structures. Among them, ultra-high performance concrete (UHPC) is widely used in long-span bridges, blast-resistant structures (military engineering, bank vaults, nuclear power plants, etc.), and thin-walled structures due to its high strength, high toughness, and high durability, as well as in highly abrasive and corrosive environments. Before the formation of ultra-high performance concrete, the fibers in the concrete need to be oriented to ensure that the fibers can be uniformly dispersed and oriented in the concrete.

[0003] Current ultra-high performance concrete fiber orientation devices mainly consist of a magnet and a lifting device that drives the magnet to move up and down. The S pole of the magnet is connected to the lifting device, and the N pole of the magnet is inserted into the concrete. Guided by the magnetic pole, the fiber can move in the direction close to the magnet. The concrete resistance experienced by the fiber at different positions is different, so the moving speed between the fibers is also different, thereby avoiding fiber agglomeration and achieving fiber orientation.

[0004] After the fibers in the concrete are oriented, the magnet is lifted off the concrete by a lifting device. At this time, a relatively thick layer of concrete will adhere to the surface of the magnet, which will not only affect the subsequent use of the magnet, but also cause some concrete waste. Summary of the Invention

[0005] The purpose of this invention is to provide a fiber orientation device for ultra-high performance concrete, which aims to solve the problem mentioned in the background art that a relatively thick layer of concrete adheres to the surface of the magnet, which not only affects the subsequent use of the magnet but also causes some concrete waste.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A fiber orientation device for ultra-high performance concrete includes a magnetic strip connected to a drive assembly, the drive assembly connected to a fixing assembly, a scraping assembly located below the magnetic strip, a slide rail located below the scraping assembly, a mold slidably connected to the slide rail, and a dust removal assembly located on one side of the mold.

[0008] The scraping component includes a plurality of fine filaments, each of which is in contact with the corresponding side of the magnet strip;

[0009] The scraping assembly is equipped with an adjustment mechanism for adjusting the tension of the filament;

[0010] The scraping assembly is equipped with a shaking mechanism, which causes the concrete mortar on the surface of the filaments to fall into the mold.

[0011] A positioning mechanism is provided between the slide rail and the mold. When the positioning mechanism is in the working position, the mold carrying ultra-high performance concrete slurry is located below the scraping component.

[0012] When the drive assembly drives the magnet strip to rise away from the mold, each of the filaments causes the concrete mortar on the surface of the magnet strip to fall into the mold.

[0013] The drive assembly drives the magnet strip into the ash removal assembly, which removes any remaining concrete mortar from the surface of the magnet strip.

[0014] Furthermore, the magnet strip is provided with a protective sleeve, which covers the outside of the magnet strip.

[0015] Furthermore, the protective sleeve includes a sleeve, a metal block, and a locking buckle. The metal block is connected to the drive assembly and is magnetically connected to the magnet strip. The sleeve is fitted around the outside of the magnet strip. When the locking buckle is in the working position, the sleeve is securely connected to the metal block.

[0016] Furthermore, the adjustment mechanism includes a sliding hole, a slider, a limiting groove, a limiting rod, a tension spring, a fixed plate, a rotating plate, a hand rudder, and an adjusting screw. The scraping assembly has a sliding hole extending from one end to the other. The sidewall of the sliding hole has a limiting groove, the length of which is less than the length of the sliding hole. The limiting groove communicates with the sliding hole. The slider is slidably connected to the sliding hole. The slider has a rotating hole extending from one end to the other. The rotating hole is connected to the rotating plate. The rotating plate is dumbbell-shaped, and the slider is equipped with a limiting rod that corresponds to the limiting groove. The end of the slider away from the limiting rod is connected to the first tension spring, and the end of the first tension spring away from the slider is connected to the fixing plate. The end of the fixing plate away from the tension spring is connected to the filament. The adjusting screw is threadedly connected to the scraping assembly. One end of the adjusting screw is connected to the rotating plate, and the other end is connected to the hand rudder. The adjusting screw can be rotated clockwise or counterclockwise to drive the slider to reciprocate along the sliding hole.

[0017] Furthermore, the shaking mechanism includes a servo motor, which is connected to the scraping assembly, and the output end of the servo motor is connected to a cam.

[0018] Furthermore, the positioning mechanism includes a receiving groove, the width of which is less than the wheel width of the mold. A compression spring is provided in the receiving groove, with its two ends connected to the bottom wall of the receiving groove and the bottom wall of the pressure plate, respectively. The end of the pressure plate away from the compression spring is hinged to the side wall of the receiving groove. The natural height of the compression spring is greater than the depth of the receiving groove. A crossbar is provided on the end of the pressure plate near the compression spring, and a hanging rod is vertically provided on the end of the crossbar away from the pressure plate. The mold is provided with a hanging hole, which is adapted to the hanging rod.

[0019] Furthermore, the hanging hole near the mold end is provided with an enlarged hole, the diameter of which is adapted to the sum of the maximum errors of the mold wheel swinging left and right along the slide rail.

[0020] Furthermore, the dust removal assembly includes a vibration mechanism located on one side of the mold. The opening end of the vibration mechanism is provided with an elastic seal. The opening of the vibration mechanism is movably connected to a cover. The cover is slidably connected to the fixing assembly. The cover is provided with a groove adapted to the magnet strip. The opening of the groove faces the magnet strip. The fixing assembly is fitted with a tension spring II. The two ends of the tension spring II are respectively connected to the corresponding fixing assembly and the cover. The fixing assembly is provided with a limiting block near the end of the vibration mechanism. When the cover abuts against the limiting block, the upper end of the elastic seal abuts against the bottom wall of the cover.

[0021] Furthermore, the vibration mechanism includes a vibrating material, which comprises at least one of quartz powder, fine aggregate, and coarse aggregate used in the preparation of ultra-high performance concrete raw materials; the elastic seal includes a lower annular plate adapted to the vibration mechanism, the lower annular plate is provided with a plurality of compression springs, each compression spring being spaced apart along the circumference of the lower annular plate, the end of the compression spring away from the lower annular plate being connected to the upper annular plate, and a flexible element covering the space between the upper annular plate and the lower annular plate.

[0022] Furthermore, the method of using fiber-oriented equipment for ultra-high performance concrete includes the following steps:

[0023] Step 1: Using the drive assembly, bring the lower end of the magnet strip close to the filament. The magnet strip attracts the filament, causing it to move towards the magnet strip. Adjust the tension of the filament using the adjustment mechanism to bring the filament into contact with the side of the magnet strip. Move the mold containing the ultra-high performance concrete slurry along the slide rail.

[0024] Step 2: When the wheel at the front end of the mold passes the positioning mechanism, the mold causes the positioning mechanism to move down. The mold moves along the slide rail. When the wheel at the rear end of the mold passes the positioning mechanism, the positioning mechanism moves up and connects to the mold. When the positioning mechanism fixes the mold, the mold is located below the scraping component.

[0025] Step 3: The drive component moves the magnet strip downward, allowing it to pass through the mesh formed by the fine filaments and enter the ultra-high performance concrete slurry in the mold for fiber orientation.

[0026] Step 4: The drive component drives the magnet strip to rise, and the filament scrapes off the concrete adhering to the surface of the magnet strip and causes the concrete to fall back into the mold; after the magnet strip is detached from the filament, the shaking mechanism is rotated, and the rotation of the shaking mechanism drives the filament to shake, causing the concrete adhering to the surface of the filament to fall into the mold.

[0027] Step 5: The drive component drives the magnet strip into the dust removal component, which removes the remaining concrete mortar from the surface of the magnet strip, keeping the surface of the magnet strip clean.

[0028] The technological advancements achieved by this invention compared to existing technologies, due to the adoption of the aforementioned structure, are as follows:

[0029] The scraping component of the present invention includes a plurality of fine filaments, each fine filament being in contact with the side of the corresponding magnetic strip. The fine filaments reduce the contact area with the concrete, further reducing the adhesion of the concrete to the surface of the fine filaments.

[0030] The adjustment mechanism of the present invention facilitates the connection of the filament and the adjustment of the tension of the filament;

[0031] The shaking mechanism of the present invention shakes the filament, causing the concrete mortar adhering to the surface of the filament to fall into the mold.

[0032] The positioning mechanism of this invention facilitates the positioning of the mold;

[0033] The driving component of the present invention drives the magnet strip to move upward, downward, and horizontally;

[0034] The dust removal component of this invention removes the remaining concrete mortar from the surface of the magnet strip, ensuring the cleanliness of the magnet strip surface.

[0035] In summary, the present invention, employing the above-described structure, improves the utilization rate of concrete and keeps the surface of the magnet strip clean, making it suitable for ultra-high performance concrete. Attached Figure Description

Detailed Implementation

[0051] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0052] This embodiment discloses a fiber orientation device for ultra-high performance concrete, such as... Figure 1 , Figure 4As shown, the assembly includes a magnet strip 1. There can be one magnet strip 1 or multiple magnet strips 1, arranged according to actual needs. The magnet strip 1 is connected to the drive assembly 2, and the connection method can be bonding, bolting, snap-fitting, etc. The drive assembly 2 includes an electric push rod 1, an electric push rod 2, a connecting plate, a sliding seat, and a slide rail. The fixing assembly 3 has a horizontal slide rail provided by the machine tool. One end of the sliding seat is connected to the extension rod of the electric push rod 1. The electric push rod 1 is connected to the fixing assembly by bolts. The extension or retraction of the electric push rod 1 drives the sliding seat to reciprocate along the slide rail. The sliding seat is connected to the electric push rod 2 by bolts. The extension rod of the electric push rod 2... A connecting plate is bolted together, with magnet strip 1 connected to the two ends of the connecting plate away from the electric push rod, and the N pole of magnet strip 1 facing downwards. The width of the connecting plate is adapted to the width of the mold 6. The extension or retraction of the electric push rod 2 drives the magnet strip 1 to move closer to or away from the mold 6. The drive assembly 2 can also adopt other drive structures, such as screw drive. The drive assembly 2 is connected to the fixing assembly 3, which includes a top plate and a vertical rod. The top plate has a horizontal slide rail opened by the machine tool, and the top plate is fixedly connected to the vertical rod by welding. The vertical rod is fixedly connected to the ground. A scraping assembly 4 is provided below the magnet strip 1. The scraping assembly 4 includes a frame and a push rod. Several longitudinal fine wires 4 are provided in the frame. A mesh is formed by several transverse filaments 401, longitudinal filaments 401, and transverse filaments 401. The mesh is adapted to the magnet strip 1. The longitudinal and transverse filaments 401 are in contact with the corresponding sides of the magnet strip 1. The filaments 401 can be made of iron wire, steel wire, metal fiber alloy wire, etc. The top rod is fixedly connected to the frame by welding. The top rod is fixedly connected to the ground. A slide rail 5 is provided below the scraping component 4. The mold 6 is slidably connected to the slide rail 5. Under the action of external force, the mold 6 carrying ultra-high performance concrete slurry slides along the slide rail 5 to the bottom of the scraping component 4 to wait for fiber orientation. The ultra-high performance concrete after fiber orientation... The slurry is carried by the mold 6 and leaves the scraping assembly 4 along the slide rail 5. The scraping assembly 4 is equipped with an adjustment mechanism 8, which is connected to a filament 401. The number of adjustment mechanisms 8 is equal to the number of filaments 401. Each filament 401 is connected to a corresponding adjustment mechanism 8. The adjustment mechanism 8 is used to adjust the tension of the corresponding filament 401 so that the filament 401 is in close contact with the surface of the magnet strip 1, reducing the residue of concrete slurry on the surface of the magnet strip 1. The scraping assembly 4 is equipped with a shaking mechanism 9, which is connected to the frame by bolts. The shaking mechanism 9 rotates to make the corresponding filament 401 shake, and the shaking mechanism 9 makes the concrete slurry on the surface of the filament 401 fall into the mold 6.A positioning mechanism 10 is provided between the slide rail 5 and the mold 6. When the positioning mechanism 10 is in the working position, the mold 6 carrying ultra-high performance concrete slurry is located below the scraping component 4, which facilitates the orientation of the fibers in the ultra-high performance concrete slurry by the magnetic strip 1. After the fibers in the ultra-high performance concrete slurry are oriented, another mold 6 carrying ultra-high performance concrete slurry slides along the slide rail 5 towards the scraping component 4. When the wheels of the other mold 6 carrying ultra-high performance concrete slurry cause the positioning mechanism 10 to move downward, the mold 6 carrying ultra-high performance concrete slurry with the completed fiber orientation leaves the scraping component 4, and the other mold 6 carrying ultra-high performance concrete slurry slides to below the scraping component 4. This arrangement allows the opening of the positioning mechanism 10 to be achieved through... The sliding of mold 6 is controlled; when the drive component 2 drives the magnet strip 1 to rise away from mold 6, the fine wires cause the concrete mortar on the surface of the magnet strip 1 to fall into mold 6, reducing the residue of concrete mortar on the surface of the magnet strip 1 and improving the utilization of concrete mortar. The drive component 2 drives the magnet strip 1 to extend into the ash removal component 7, which removes the remaining concrete mortar on the surface of the magnet strip 1. The ash removal component 7 can remove the concrete mortar on the surface of the magnet strip 1 by washing with water or by friction. The ash removal component 7 avoids the residue of concrete mortar on the surface of the magnet strip 1, thus increasing the service life of the magnet strip 1. In use, firstly, the drive component 2... The magnet strip 1 is brought close to the filament 401, generating an attractive force on it. The filament 401 is then brought close to the magnet strip 1. The tension of the filament 401 is adjusted using the adjusting mechanism 8, bringing it into contact with the side of the magnet strip 1. Next, ultra-high performance concrete mortar is poured into the mold 6, and the mold 6 is moved along the slide rail 5 towards the scraping component 4. Then, when the wheel at the front end of the mold 6 passes the positioning mechanism 10, the mold 6 causes the positioning mechanism 10 to move downwards. The mold 6 moves along the slide rail 5. After the wheel passes the positioning mechanism 10, one end of the positioning mechanism 10 tilts up, and the tilted end of the positioning mechanism 10 abuts against the bottom wall of the mold 6. The tilted end of the positioning mechanism 10 slides against the bottom wall of the mold 6. When the wheel at the rear end of the mold 6 passes... After the positioning mechanism 10 moves upward and connects to the mold 6, the mold 6 is located below the scraping component 4 when the positioning mechanism 10 fixes the mold 6. Then, the driving component 2 drives the magnet strip 1 downward, so that the magnet strip 1 extends into the ultra-high performance concrete slurry in the mold 6 through the mesh formed by the filament 401 for fiber orientation. After the orientation is completed, the driving component 2 drives the magnet strip 1 upward, and the filament 401 scrapes off the concrete adhering to the surface of the magnet strip 1 and makes the concrete fall back into the mold 6. After that, when the magnet strip 1 is separated from the filament 401, the shaking mechanism 9 is rotated. The rotation of the shaking mechanism 9 drives the filament 401 to shake, so that the concrete adhering to the surface of the filament 401 falls into the mold 6.If the shaking mechanism 9 rotates to drive the filament 401 to shake when the magnet strip 1 rises, the filament 401 may briefly move away from the surface of the magnet strip 1, preventing the filament 401 from removing the concrete from the surface of the magnet strip 1. This results in excessive concrete residue on the surface of the magnet strip 1. Finally, the driving component 2 drives the magnet strip 1 into the dust removal component 7, which removes the remaining concrete mortar from the surface of the magnet strip 1, keeping the surface of the magnet strip 1 clean and extending its service life. Therefore, the advantage of this embodiment is that by adopting the above-mentioned arrangement, the utilization rate of concrete is improved, the surface of the magnet strip 1 is kept clean, and the service life of the magnet strip 1 is extended.

[0053] like Figure 1 , Figure 7 , Figure 8 As shown, the magnet strip 1 is provided with a protective sleeve 11, which covers the outside of the magnet strip 1. The protective sleeve 11 can prevent the magnet strip 1 from directly contacting the concrete mortar. The protective sleeve 11 can be made of plastic or metal. The wall thickness of the protective sleeve 11 is between 0.1 and 1.0 mm, such as 0.1 / 0.25 / 0.5 / 0.8 / 1.0 mm. The protective sleeve 11 can both ensure that the magnet strip 1 does not directly contact the concrete and can also be used to orient the fibers. Compared with the magnet strip 1, the protective sleeve 11 is lower in cost and saves money, which can improve the company's operating profit. The protective sleeve 11 includes a sleeve 1101, a metal block 1102, and a locking buckle 1. 103. The metal block 1102 can be fixedly connected to the drive component 2 by welding or by bolting. The cross-section of the metal block 1102 is adapted to the cross-section of the magnet strip 1. The metal block 1102 is connected to the magnet strip 1 by magnetic attraction. The sleeve 1101 is sleeved on the outside of the magnet strip 1 and the metal block 1102. When the locking buckle 1103 is in the working position, the sleeve 1101 is tightly connected to the metal block 1102. The locking buckle 1103 can be connected by bolts, lock buckles, etc. The length of the sleeve 1101 is less than the sum of the length of the magnet strip 1 and the height of the metal block 1102, but greater than the length of the magnet strip 1.

[0054] like Figure 1 , Figure 4 , Figure 5 , Figure 9As shown, the adjustment mechanism 8 includes a sliding hole 801, a slider 802, a limiting groove 803, a limiting rod 804, a tension spring 805, a fixed plate 806, a rotating plate 807, a hand rudder 808, and an adjusting screw 809. The scraping assembly 4 has a sliding hole 801 formed by a machine tool, extending from one end of the scraping assembly 4 to the other. A limiting groove 803 is formed on the side wall of the sliding hole 801 by a machine tool. The length of the limiting groove 803 is less than the length of the sliding hole 801, and the limiting groove 803 is connected to the sliding hole 801. The slider 802 is slidably connected to the sliding hole 801. The slider 802 has a rotating hole 80201 formed by a machine tool, and the rotating hole 80201 is connected to the slider 802. 2 extends from one end to the other. The rotating hole 80201 is adapted to the rotating plate 807, which is dumbbell-shaped. The diameter of the rotating hole 80201 is adapted to the diameter of the central axis of the dumbbell-shaped rotating plate 807. The slider 802 is fixedly connected to the limiting rod 804 by welding. The limiting rod 804 corresponds to the limiting groove 803. This setting improves the stability of the slider 802 and prevents the slider 802 from coming out of the sliding hole 801. The end of the slider 802 away from the limiting rod 804 is fixedly connected to the tension spring 805 by welding. The end of the tension spring 805 away from the slider 802 is fixedly connected to the fixing plate 806 by welding. The end of the tension spring 805 is connected to the thin wire 401. The tension spring 805 improves the service life of the thin wire 401. Since the thin wire 401 itself is not elastic, its length is fixed after the tension is adjusted. When the vibrating mechanism 9 rotates, driving the thin wire 401 to move downwards or upwards, the thin wire 401 is prone to breakage and needs replacement. The tension spring 805 is placed between the thin wire 401 and the slider 802. After the tension of the thin wire 401 is adjusted by the adjusting mechanism 8, when the vibrating mechanism 9 rotates, driving the thin wire 401 to move downwards or upwards, the thin wire 401 pulls the tension spring 805 to extend. After the shaking mechanism 9 disengages from the filament 401, the filament 401 returns to its tension under the action of the tension spring 805, which increases the service life of the filament 401 and saves time. The other end of the filament 401 is connected to the other end of the scraping assembly 4. The adjusting screw 809 is threadedly connected to the scraping assembly 4. One end of the adjusting screw 809 is connected to the rotating plate 807, and the other end of the adjusting screw 809 is connected to the hand rudder 808. The adjusting screw 809 rotates clockwise or counterclockwise to drive the slider 802 to reciprocate along the sliding hole 801. The rotating plate 807 can prevent the filament 401 from rotating along with the adjusting screw 809 during rotation, thus improving the stability of the filament 401.

[0055] like Figure 1 , Figure 4 , Figure 6As shown, the shaking mechanism 9 includes a servo motor 901, which is bolted to the scraping assembly 4. The output end of the servo motor 901 is keyed to a cam 902. The cam 902 can be single-headed, located on one side of the corresponding filament 401. The servo motor 901 drives the cam 902 to rotate 180 degrees. During the rotation, the cam 902 causes the corresponding filament 401 to move downwards or upwards. When the cam 902 leaves the filament 401, the filament 401 vibrates, causing the concrete on its surface to fall into the mold 6. Alternatively, the cam 902 can be double-headed, located between two corresponding filaments 401. The servo motor 901 drives the cam 902 to rotate 180 degrees, causing the corresponding filament 401 to move downwards or upwards during the rotation. When the cam 902 leaves the filament 401, the filament 401 vibrates, causing the concrete on its surface to fall into the mold 6.

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the positioning mechanism 10 includes a receiving groove 1001. The slide rail 5 has the receiving groove 1001 cut into it by a machine tool. The width of the receiving groove 1001 is smaller than the wheel width of the mold 6, and the depth of the receiving groove 1001 is smaller than the height of the slide rail 5. A compression spring 1002 is provided inside the receiving groove 1001. The two ends of the compression spring 1002 are fixedly connected to the bottom wall of the receiving groove 1001 and the bottom wall of the pressure plate 1003 by welding, respectively. The end of the pressure plate 1003 away from the compression spring 1002 is hinged to the side wall of the receiving groove 1001. The natural height of compression spring 1002 is greater than the depth of receiving groove 1001. The wheel of mold 6 moves from the hinged end of pressure plate 1003 to the end of compression spring 1002. During the movement, the wheel causes pressure plate 1003 to move downwards, compressing compression spring 1002. After the wheel leaves pressure plate 1003, compression spring 1002 returns to its original position, causing pressure plate 1003 to rise. The end of pressure plate 1003 near compression spring 1002 is fixedly connected to crossbar 1004 by welding. The end of crossbar 1004 away from pressure plate 1003... Hanging rod 1005 is fixedly connected by welding. Hanging rod 1005 is vertically arranged. Mold 6 has hanging holes 1006 opened by a machine tool. Hanging holes 1006 are located on the bottom wall of mold 6. The length direction of hanging hole 1006 is the same as the sliding direction of mold 6. Hanging hole 1006 is adapted to hanging rod 1005. Mold 6 can also be fixedly connected to hanging plate by welding. Hanging plate has hanging holes 1006 opened by a machine tool. After the wheel of mold 6 passes through positioning mechanism 10, compression spring 1002 returns to its original position and drives pressure plate 100. 3. The pressure plate 1003 rises, which drives the hanging rod 1005 to rise via the crossbar 1004. The hanging rod 1005 rises and extends into the hanging hole 1006, stopping the mold 6 from moving and achieving the purpose of positioning. The hanging hole 1006 near the mold 6 has an enlarged hole 1007 opened by the machine tool. The enlarged hole 1007 is arranged in a ring shape. The ring-shaped enlarged hole 1007 facilitates the sliding of the hanging rod 1005. The diameter of the enlarged hole 1007 is matched with the sum of the maximum errors of the wheel of the mold 6 swinging left and right along the slide rail 5, which improves the positioning success rate.

[0057] like Figure 1 , Figure 4 , Figure 10 , Figure 11 , Figure 12As shown, the dust removal component 7 includes a vibration mechanism 701. The vibration mechanism 701 adopts an existing vibratory polishing machine, or it can be customized according to actual needs. The vibration mechanism 701 is located on one side of the mold 6. The open end of the vibration mechanism 701 is connected to an elastic seal 702 by bolts. The opening of the vibration mechanism 701 is movably connected to a cover 703. The cover 703 is slidably connected to a fixing component 3. The cover 703 is provided with a groove 704 adapted to the magnet strip 1 by a machine tool. The opening of the groove 704 faces the magnet strip 1. The drive component 2 drives the magnet strip 1 to extend into the cover 703 through the groove 704. The fixing component 3 is fitted with a tension spring 705. The two ends of the tension spring 705 are fixedly connected to each other by welding. The fixing component 3 and the cover 703 are fixedly connected to the limiting block 706 near the end of the vibration mechanism 701 by welding. The driving component 2 drives the magnet strip 1 to move the cover 703 downward so that the cover 703 abuts against the limiting block 706, allowing the magnet strip 1 to extend into the vibration mechanism 701. The downward movement of the cover 703 causes the tension spring 705 to stretch. When the cover 703 abuts against the limiting block 706, the upper end of the elastic seal 702 abuts against the bottom wall of the cover 703. This arrangement reduces the gap between the vibration mechanism 701 and the cover 703, improving the sealing performance. During the vibration of the vibration mechanism 701, the elastic seal 702 deforms with the vibration frequency. The elastic seal 702 ensures the vibration of the vibration mechanism 701. The stability of the cap 703 is ensured. When the drive assembly 2 drives the magnet strip 1 to rise and disengage from the vibration mechanism 701, the tension spring 705 retracts, causing the cap 703 to move away from the vibration mechanism 701. The vibration mechanism 701 contains vibrating material. The vibrating material can be an abrasive to remove the remaining mortar on the surface of the magnet strip 1. Alternatively, the vibrating material can be at least one of quartz powder, fine aggregate, and coarse aggregate used in the preparation of ultra-high performance concrete raw materials to remove the remaining mortar on the surface of the magnet strip 1. Using quartz powder, fine aggregate, and coarse aggregate to remove mortar also allows the mortar to be utilized, improving the utilization rate of the mortar. During the vibration process, the vibration mechanism 701 rubs the concrete mortar on the surface of the magnet strip 1 through the movement of quartz powder, fine aggregate, and coarse aggregate. The elastic seal 702 includes a lower annular plate 70201, which is adapted to the vibration mechanism 701. The lower annular plate 70201 is fixedly connected to a plurality of compression springs 70202 by welding. The plurality of compression springs 70202 are spaced apart circumferentially along the lower annular plate 70201. The ends of the compression springs 70202 away from the lower annular plate 70201 are fixedly connected to an upper annular plate 70203 by welding. A flexible element 70204 is wrapped between the upper annular plate 70203 and the lower annular plate 70201. The material of the flexible element 70204 can be rubber, silicone, cloth, etc. The flexible element 70204 is fixedly connected to the corresponding upper annular plate 70203 or lower annular plate 70201 by riveting.

[0058] A method of using a fiber orientation device for ultra-high performance concrete includes the following steps:

[0059] Step 1: Drive the lower end of the magnet strip 1 close to the filament 401 through the drive component 2. The magnet strip 1 generates an attractive force on the filament 401, causing the filament 401 to move toward the magnet strip 1. Adjust the tension of the filament 401 through the adjustment mechanism 8 so that the filament 401 contacts the side of the magnet strip 1. Move the mold 6 containing the ultra-high performance concrete slurry along the slide rail 5.

[0060] Step 2: When the wheel at the front end of the mold 6 passes the positioning mechanism 10, the mold 6 causes the positioning mechanism 10 to move down. The mold 6 moves through the slide rail 5. When the wheel at the rear end of the mold 6 passes the positioning mechanism 10, the positioning mechanism 10 moves up and connects to the mold 6. When the positioning mechanism 10 fixes the mold 6, the mold 6 is located below the scraping component 4.

[0061] Step 3: Drive component 2 drives magnet strip 1 to move downward, so that magnet strip 1 extends into the ultra-high performance concrete slurry in mold 6 through the mesh formed by filament 401 for fiber orientation;

[0062] Step 4: Drive component 2 drives magnet strip 1 to rise, and filament 401 scrapes off the concrete adhering to the surface of magnet strip 1 and causes the concrete to fall back into mold 6; after magnet strip 1 is separated from filament 401, the shaking mechanism 9 is rotated, and the rotation of shaking mechanism 9 drives filament 401 to shake, causing the concrete adhering to the surface of filament to fall into mold 6.

[0063] Step 5: Drive component 2 drives magnet strip 1 to extend into ash removal component 7. Ash removal component 7 removes the remaining concrete mortar on the surface of magnet strip 1, keeping the surface of magnet strip 1 clean.
