Description

Technical Field

[0002] In the field of building materials, concrete is the most widely used one, and its performance directly affects the safety and durability of building structures. Among them, ultra-high performance concrete (UHPC) is widely used in large-span bridges, explosion-proof structures (military projects, 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 highly 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 evenly dispersed and oriented in the concrete.

[0003] The current ultra-high performance concrete fiber orienting device mainly includes a magnet and a lifting device that drives the magnet to rise and fall. The S pole of the magnet is connected to the lifting device, and the N pole of the magnet is inserted into the concrete. The fiber can be moved in the direction close to the magnet through the guidance of the magnetic pole. The fibers at different positions are subject to different concrete resistance, so the movement speeds of the fibers are also different, thereby avoiding fiber agglomeration and achieving fiber orientation.

The top plate is provided with a horizontal slideway through the machine tool. The top plate is fixedly connected to the vertical rod by welding, and the vertical rod is fixedly connected to the ground; a scraping component 4 is provided below the magnet strip 1, and the scraping component 4 includes a frame and a top rod, and a plurality of longitudinal filaments 4 are provided in the frame 01 and a plurality of transverse filaments 401, the longitudinal filaments 401 and the transverse filaments 401 form a mesh, the mesh is adapted to the magnet bar 1, the longitudinal filaments 401 and the transverse filaments 401 are in contact with the corresponding sides of the magnet bar 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, and the top rod is fixedly connected to the ground; a slide rail 5 is provided under the scraping component 4, and the mold 6 is slidably connected to the slide rail 5. Under the action of external force, the mold 6 carrying the 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 leaves the scraping assembly 4 along the slide rail 5 under the mold 6; the scraping assembly 4 is provided with an adjusting mechanism 8, the adjusting mechanism 8 is connected to the filaments 401, the number of the adjusting mechanisms 8 is equal to the number of the filaments 401, each filament 401 is connected to the corresponding adjusting mechanism 8, the adjusting mechanism 8 is used to adjust the tightness of the corresponding filament 401, so that the filament 401 is close to the surface of the magnet strip 1, and the residual concrete slurry on the surface of the magnet strip 1 is reduced; the scraping assembly 4 is provided with a shaking mechanism 9, the shaking mechanism 9 is connected to the frame by bolts, the shaking mechanism 9 rotates to shake the corresponding filament 401, 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 the ultra-high performance concrete slurry is located below the scraping assembly 4, which is convenient for the magnet bar 1 to orient the fibers in the ultra-high performance concrete slurry. After the fiber orientation in the ultra-high performance concrete slurry is completed, another mold 6 carrying the ultra-high performance concrete slurry slides along the slide rail 5 toward the end of the scraping assembly 4. When the wheels of the other mold 6 carrying the ultra-high performance concrete slurry move the positioning mechanism 10 downward, the mold 6 of the ultra-high performance concrete slurry that has completed the fiber orientation leaves the scraping assembly 4, and the other mold 6 carrying the ultra-high performance concrete slurry slides to below the scraping assembly 4. This arrangement allows the positioning mechanism 10 to be opened by The mold 6 is controlled by sliding; when the driving component 2 drives the magnet strip 1 to rise and away from the mold 6, each filament causes the concrete mortar on the surface of the magnet strip 1 to fall into the mold 6, reducing the residual concrete mortar on the surface of the magnet strip 1 and improving the utilization of the concrete mortar. The driving component 2 drives the magnet strip 1 to extend into the ash removal component 7, and the ash removal component 7 removes the remaining concrete mortar on the surface of the magnet strip 1. The ash removal component 4 can remove the concrete mortar on the surface of the magnet strip 1 by water washing, and the ash removal component 7 can also remove the concrete mortar on the surface of the magnet strip 1 by friction. The setting of the ash removal component 7 avoids the residual concrete mortar on the surface of the magnet strip 1 and improves the service life of the magnet strip 1. When using, first, drive the driving component 2 The magnet strip 1 is brought close to the filament 401 and generates suction to the filament 401, so that the filament 401 is brought close to the magnet strip 1. The tightness of the filament 401 is adjusted by adjusting the component 8 so that the filament 401 contacts the side of the magnet strip 1. Then, ultra-high performance concrete mortar is loaded into the mold 6, and the mold 6 is moved along the slide rail 5 toward the end of the scraping component 4.

When the positioning mechanism 10 fixes the mold 6, the mold 6 is located below the scraping component 4. Then, the driving component 2 drives the magnet bar 1 to move down, so that the magnet bar 1 extends into the ultra-high performance concrete slurry in the mold 6 through the mesh formed by the filament 401 to perform fiber orientation. After that, after the orientation is completed, the driving component 2 drives the magnet bar 1 to rise, and the filament 401 scrapes off the concrete adhered to the surface of the magnet bar 1 and makes the concrete fall into the mold 6 again; then, when the magnet bar 1 is separated from the filament 401, the shaking component 9 is rotated, and the shaking component 9 rotates to drive the filament 401 to shake, so that the concrete adhered to the surface of the filament 401 falls into the mold 6;If the shaking assembly 9 is rotated to drive the filament 401 to shake when the magnet bar 1 rises, the filament 401 is easily moved away from the surface of the magnet bar 1 for a short time, so that the filament 401 cannot make the concrete on the surface of the magnet bar 1 fall off, thereby causing excessive concrete to remain on the surface of the magnet bar 1. Finally, the driving assembly 2 drives the magnet bar 1 to extend into the ash removal assembly 7, and the ash removal assembly 7 removes the remaining concrete mortar on the surface of the magnet bar 1, so that the surface of the magnet bar 1 is kept clean and the service life of the magnet bar 1 is extended. Therefore, the advantage of this embodiment is that the above-mentioned setting is adopted to improve the utilization rate of concrete, keep the surface of the magnet bar 1 clean, and extend the service life of the magnet bar 1. ;

[0054] like Figure 1 , Figure 7 , Figure 8 As shown, the magnet strip 1 is provided with a protective cover 11, which is coated on the outside of the magnet strip 1. The protective cover 11 can prevent the magnet strip 1 from directly contacting the concrete mortar. The protective cover 11 can be made of plastic or metal. The wall thickness of the protective cover 11 is between 0.1 and 1.0 mm, such as 0.1 / 0.25 / 0.5 / 0.8 / 1.0 mm. The protective cover 11 can ensure that the magnet strip 1 does not directly contact the concrete and can use the magnet strip 1 to orient the fibers. Compared with the magnet strip 1, the protective cover 11 has a low cost, saves money, and can increase the company's operating profit. The protective cover 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 driving component 2 by welding, and the metal block 1102 can also be connected to the driving component 2 by bolting.

The locking buckle 1103 can be connected by bolts, locks, etc. The length of the sleeve 1101 is less than the sum of the length of the magnet bar 1 and the height of the metal block 1102, but greater than the length of the magnet bar 1.

[0055] like Figure 1 , Figure 4 , Figure 5 , Fig. 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 fixing plate 806, a rotating plate 807, a hand rudder 808 and an adjusting screw 809. The scraping component 4 is provided with a sliding hole 801 through a machine tool. The sliding hole 801 extends from one end to the other end of the scraping component 4. The side wall of the sliding hole 801 is provided with a limiting groove 803 through a machine tool. The length of the limiting groove 803 is less than the length of the sliding hole 801. 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 is provided with a rotating hole 80201 through a machine tool. The rotating hole 80201 is connected to the slider 80 2 extends from one end to the other end, the rotating hole 80201 is adapted to the rotating plate 807, the rotating plate 807 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 arrangement improves the stability of the slider 802, and prevents the slider 802 from slipping 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, and the fixing plate 806 is fixedly connected to the fixing plate 806. 06 is connected to the filament 401 away from the end of the stretch spring 805. The setting of the stretch spring 805 increases the service life of the filament 401. Since the filament 401 itself is not ductile, when the tightness of the filament 401 is adjusted, the length of the filament 401 is fixed. When the shaking mechanism 9 rotates to drive the filament 401 to move downward or upward, the filament 401 is easily broken and needs to be replaced and repaired; and a stretch spring 805 is set between the filament 401 and the slider 802. After the tightness of the filament 401 is adjusted by the adjusting mechanism 8, when the shaking mechanism 9 rotates to drive the filament 401 to move downward or upward, the filament 401 pulls the stretch spring 805 to extend. When the shaking mechanism 9 disengages from the filament 401, the filament 401 recovers its tightness under the action of the tension spring 805, thereby increasing the service life of the filament 401 and saving time; the other end of the filament 401 is connected to the other end of the scraping assembly 4, and 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 setting of the rotating plate 807 can prevent the filament 401 from rotating during the rotation of the adjusting screw 809, thereby improving the stability of the filament 401.

[0056] like Figure 1 , Figure 4 , Figure 6As shown, the shaking mechanism 9 includes a servo motor 901, which is connected to the scraping component 4 by bolts, and the output end of the servo motor 901 is connected to the cam 902 by a key. The cam 902 can be single-headed, and the single-headed cam 902 is located on one side of the corresponding filament 401. The servo motor 902 drives the cam 902 to rotate 180 degrees. During the rotation, the cam 902 causes the corresponding filament 401 to move downward or upward. When the cam 902 leaves the filament 401, the filament 401 shakes, so that the concrete on the surface of the filament 401 falls into the mold 6. The cam 902 can also be double-headed, and the double-headed cam 902 is located between the two corresponding filaments 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 downward or upward.

The pressure plate 1003 is hinged to the side wall of the receiving groove 1001 away from the end of the compression spring 1002. The natural height of the compression spring 1002 is greater than the depth of the accommodating groove 1001. The wheel of the mold 6 moves from the hinged end of the pressure plate 1003 to the end of the compression spring 1002. During the movement, the wheel moves the pressure plate 1003 downward to compress the compression spring 1002. After the wheel leaves the pressure plate 1003, the compression spring 1002 resets and drives the pressure plate 1003 to rise. The pressure plate 1003 is close to the end of the compression spring 1002 and is fixedly connected to the cross bar 1004 by welding.
