Description

Technical Field

[0001] The invention relates to the technical field of beam prefabricated component preparation, in particular to a beam prefabricated component preparation device using multi-fiber coordinated magnetic force guided steel fibers. Background Art

[0002] In the field of civil engineering and building materials, fiber concrete, as a high-performance composite material, has attracted much attention due to its excellent crack resistance, durability and bearing capacity. Although fiber concrete has shown great potential in enhancing structural strength and toughness, it still faces a series of defects in practical applications. The primary problem lies in the distribution of fibers inside the concrete. Using the traditional method of laying fibers, the fibers in the concrete are often unevenly and randomly distributed, which not only limits the effective utilization of the fibers, but also the proportion of fibers that actually participate in the force and play a reinforcing role is low.

[0003] The poor fluidity of fiber concrete is particularly prominent. Since the addition of fibers reduces the slump of concrete, the fluidity of concrete during mixing, transportation and pouring is significantly reduced, which not only increases the difficulty of construction, but also increases the load of machine pumping operation, resulting in overall low efficiency and a large consumption of manpower and material resources. Especially in the construction of large or complex structures, the poor fluidity of fiber concrete has become one of the key factors restricting construction efficiency and quality.

[0004] In addition, in cold regions or during winter construction, winter maintenance of concrete becomes another major problem. Under low temperature conditions, the hydration reaction of concrete slows down and the strength develops slowly. However, traditional maintenance methods often make it difficult to ensure that the concrete receives sufficient heat and uniform temperature distribution in winter, and the operation process is cumbersome. This not only prolongs the maintenance cycle, but may also cause microcracks inside the concrete due to uneven heating, seriously affecting its final performance. To this end, we have introduced a beam prefabricated component preparation device with multi-fiber coordinated magnetic-guided steel fibers. Summary of the invention

[0113] like Figure 7 , 8 , 9, 10 and 11, the bonding fiber slurry pumping system 302 includes a bonding liquid tank 30201, a first outer cylinder 30210 and a rubber buffer sealing tube 305 installed at the front end of a baffle 307 at the front of the molding and curing box 10;

[0114] The front of the molding and curing box 10 is opened, so that after the molding and curing box 10 is driven to move by the support wheels on the support seat 607, the front opening of the molding and curing box 10 can be sealed by the baffle 307.

[0115] The first outer cylinder 30210 has symmetrically disposed two ends of an adhesive fiber slurry drum 30203, and a plurality of groups of scraping paddles 30206 are evenly spaced on the inner wall of the adhesive fiber slurry drum 30203. The first outer cylinder 30210 has symmetrically disposed first box bodies 30212 on the sides thereof, and a first roller driving motor 30204 is mounted on the sides of the first box bodies 30212. A first driving roller 30205 driven by the first roller driving motor 30204 is disposed inside the first box bodies 30212, and the first driving roller 30205 is closely attached to the side wall of the adhesive fiber slurry drum 30203.

[0116] The adhesive liquid tank 30201 is provided with a metering pump 30202, and the liquid outlet of the metering pump 30202 is connected to a collecting pipe 30209 by a bonding liquid pipe 30208.

[0117] The first roller driving motor 30204, the metering pump 30202 and the slurry electric valve 30207 are all controlled by a PLC controller. After the slurry electric valve 30207 is opened, the metering pump 30202 works to introduce the adhesive liquid in the adhesive liquid tank 30201 into the first outer cylinder 30210 through the adhesive liquid pipe 30208, the liquid collecting pipe 30209 and the adhesive liquid branch pipe 30211;

[0118] The first roller driving motor 30204 works, so that the first driving roller 30205 drives the bonding fiber slurry roller 30203 to rotate, so that the scraping paddle 30206 scoops up the adhesive liquid inside the bonding fiber slurry roller 30203, so that the adhesive liquid is evenly attached to the surface of the rubber expansion tube 30602.

[0119] like Figure 7 , 8 , 9, 10, 12, 14, 15 and 16, the fiber conveying system 303 includes a non-metallic fiber material box 30301, a non-metallic fiber first conveyor belt shell 30302 located in front of the baffle 307, a second outer cylinder 30310 fixed between the front end of the rubber buffer sealing tube 305 and the rear end of the first outer cylinder 30210, and a non-metallic fiber second conveyor belt shell 30306 connected to the inner side of the non-metallic fiber first conveyor belt shell 30302 and the middle part of the second outer cylinder 30310;

[0120] The non-metallic fibers in the non-metallic fiber box 30301 may be polypropylene fibers or other non-metallic fibers.

[0121] Since the non-metallic fiber second conveyor belt shell 30306 inside the non-metallic fiber first conveyor belt shell 30302 needs to be connected to the second outer cylinder 30310 at different positions, the shape of the non-metallic fiber second conveyor belt shell 30306 needs to be adjusted accordingly according to different positions;

[0122] The lower side of the non-metallic fiber first conveyor belt housing 30302 extends into the non-metallic fiber material box 30301 and is sealed by the material box interface frame 30304;

[0123] A first conveyor belt 30305 driven by a first conveyor belt motor 30303 is disposed inside the non-metallic fiber first conveyor belt housing 30302, and a second conveyor belt 30313 driven by a second conveyor belt motor 30314 is disposed inside the non-metallic fiber second conveyor belt housing 30306;

[0124] The first conveyor belt motor 30303 and the second conveyor belt motor 30314 are controlled by a PLC controller. The first conveyor belt motor 30303 drives the first conveyor belt 30305 to work, so that the first conveyor belt 30305 conveys the non-metallic fibers in the non-metallic fiber material box 30301 to the inside of the non-metallic fiber first conveyor belt housing 30302;

[0125] At this time, the second conveyor belt motor 30314 drives the second conveyor belt 30313 to transport the non-metallic fibers in the non-metallic fiber first conveyor belt housing 30302 to the non-metallic fiber second conveyor belt housing 30306, and finally allows the non-metallic fibers to enter the bonding fiber roller 30307 inside the second outer cylinder 30310;

[0126] The second outer cylinder 30310 has symmetrically disposed two ends of the inner part thereof with adhesive fiber rollers 30307, ​​and the inner wall of the adhesive fiber roller 30307 has a plurality of groups of fiber disturbance paddles 30309 distributed at equal intervals, and the second outer cylinder 30310 has symmetrically disposed second box bodies 30312 on the sides thereof, and a second roller driving motor 30311 is installed on the sides of the second box bodies 30312, and a second driving roller 30308 driven by the second roller driving motor 30311 is disposed inside the second box bodies 30312, and the second driving roller 30308 is closely attached to the side wall of the adhesive fiber roller 30307;

[0127] The rear of the fiber bonding rod module 306 passes through the bonding fiber slurry drum 30203, the bonding fiber drum 30307, ​​the rubber buffer sealing tube 305 and the opening on the baffle 307;

[0128] The second roller drive motor 30311 is controlled by a PLC controller. The second roller drive motor 30311 drives the bonding fiber roller 30307 to rotate through the second drive roller 30308. The non-metallic fibers in the bonding fiber roller 30307 are scooped up by the fiber disturbance paddle 30309 and attached to the adhesive liquid on the surface of the rubber expansion tube 30602.

[0129] like Fig. 9 , 10 As shown in Figure 13, the rubber buffer sealing tube 305 includes a flange 30502 fixed to the outer side of the opening on the baffle 307 by bolts 30501, a ring seat 30505 connected to the outer side of the front of the flange 30502 through a rubber tube 30503, a mounting ring 30504 provided on the outer side of the rear of the ring seat 30505, an electric cylinder 30506 symmetrically provided at the front end of the mounting ring 30504, a moving ring 30507 connected to the piston rod at the output end of the electric cylinder 30506, and an elastic rubber ring 30509 located at the front of the rubber tube 30503;

[0131] The electric cylinder 30506 is controlled by a PLC controller. The piston rod of the electric cylinder 30506 extends, so that the movable ring 30507 pulls the elastic rubber ring 30509 open through the traction wire 30508. After the elastic rubber ring 30509 is opened, when the fiber bonding rod module 306 moves backward and is inserted into the molding and curing box 10, the non-metallic fibers attached to the surface of the fiber bonding rod module 306 will not be scraped off by the elastic rubber ring 30509.

[0132] After the fiber bonding rod module 306 moves backward and is inserted into the molding and curing box 10, the piston rod of the electric cylinder 30506 retracts. At this time, the elastic rubber ring 30509 retracts and closes and is tightly wrapped around the outside of the fiber bonding rod module 306 to prevent the concrete slurry inside the molding and curing box 10 from seeping out from the gap between the fiber bonding rod module 306 and the rubber buffer sealing tube 305.

[0133] The fiber rod motion system 304 is used to drive the fiber bonding rod module 306 attached with non-metallic fibers to rotate, so that the rear portion of the fiber bonding rod module 306 is inserted into the molding and curing box 10, and then drives the fiber bonding rod module 306 to spirally move, so that the rear portion of the fiber bonding rod module 306 is separated from the non-metallic fibers and then pulled out of the molding and curing box 10;

[0134] like Fig. 9 , 17, 21 and 22, the fiber rod motion system 304 includes a rectangular plate 30409 connected to the rear of the mounting frame 30411 by a traction spring 30406, a fiber bonding rod driving assembly 30403 arranged at the front end of the rectangular plate 30409, a carbide mandrel 30402 fixed to the front end of the rectangular plate 30409 by an H-shaped frame 30412, and a mandrel driving turntable 30405 installed at the rear of the mounting frame 30411;

A sliding seat driving motor 30407 is installed on the sliding seat 30410. The bottom of the sliding seat driving wheel 30416 at the output end of the sliding seat driving motor 30407 is closely attached to the upper end surface of the front and rear guide rails 30415.

[0136] The sliding seat driving motor 30407 is controlled by a PLC controller. The sliding seat driving motor 30407 drives the sliding seat driving wheel 30416 to roll on the upper surface of the front and rear guide rails 30415, so that the mounting frame 30411, the rectangular plate 30409 and the fiber bonding rod module 306 can move forward and backward.

The front end of the carbide push rod 30402 extends into the push rod driving spiral track 30401.

[0138] The turntable motor 30408 ​​is controlled by a PLC controller. The turntable motor 30408 ​​drives the push rod to drive the turntable 30405 to rotate back and forth, so that the front end of the carbide push rod 30402 slides accordingly in the push rod driving spiral track 30401, so that the carbide push rod 30402 drives the fiber bonding rod module 306 to perform spiral motion through the H-shaped frame 30412 and the rectangular plate 30409, so as to realize the separation of the fiber bonding rod module 306 from the non-metallic fibers adhered to its outside.

[0139] like Fig.17 and 18 As shown, the fiber bonding rod driving assembly 30403 includes a gear box 304031 fixed at the front end of a rectangular plate 30409, a first gear 304032 and a second gear 304034 movably connected inside the gear box 304031, and a third gear 304033 fixed on the driving rod 30404 at the front end of the gear box 304031;

[0140] The driving rod 30404 is connected between the bearing seats 30414 at the front end of the gear box 304031. The driving rod 30404 is driven by the driving rod motor 30413. The third gear 304033 is meshed with the second gear 304034. The second gear 304034 is meshed with the first gear 304032. The front end of the metal substrate 30601 penetrates the rectangular plate 30409 and extends into the gear box 304031 and is fixed to the first gear 304032.

[0141] The driving rod motor 30413 is controlled by a PLC controller. The driving rod motor 30413 drives the third gear 304033 to rotate through the driving rod motor 30413, and the third gear 304033 drives the first gear 304032 to rotate through the second gear 304034, so that the first gear 304032 drives the fiber bonding rod module 306 to rotate, which can prevent the non-metallic fibers adhered to the outside of the fiber bonding rod module 306 from falling off under the action of gravity.

[0142] In addition, the air intake branch pipe 301041 is inserted into the air intake channel 306012 at the front end of the metal base 30601, so that while introducing air into the air intake channel 306012 through the air intake branch pipe 301041, the rotation of the fiber bonding rod module 306 is not hindered.

[0143] The steel fiber placement module 4 is used to magnetize the steel fibers and place them inside the concrete slurry in the forming and curing box 10;

[0148] The grabbing motor 402 is controlled by a PLC controller. When the grabbing motor 402 is working, the steel fiber grabbing conveyor belt 418 rotates, so that after the grabbing electromagnet 401 is powered on, the steel fiber at the outlet slot 421 is sucked. When the steel fiber is transported to the top of the steel fiber magnetized conveyor belt 406, the corresponding grabbing electromagnet 401 is powered off, and the steel fiber falls on the steel fiber magnetized conveyor belt 406 under the action of its own gravity.

[0149] A magnetizing conveyor belt motor 420 for driving the steel fiber magnetizing conveyor belt 406 is installed on the side of the magnetizing frame 417, and a plurality of sets of magnetizing electromagnets connected in series are also provided on the magnetizing frame 417, and the magnetizing electromagnets are located inside the steel fiber magnetizing conveyor belt 406;

The PLC controller controls the laying electromagnet to generate suction to absorb the magnetized steel fibers on the steel fiber magnetizing conveyor belt 406. When the steel fibers move to the bottom of the steel fiber conveying conveyor belt 411, the corresponding laying electromagnet is powered off, so that the steel fibers fall into the forming and curing box 10 under the action of their own gravity.

[0153] like Figure 5 As shown, a front and rear track 410 is provided between the inner side walls of the steel fiber conveying guide rail frame 409, and the front and rear tracks 410 are sleeved with a middle moving seat 208 and side moving seats 209 located on both sides of the middle moving seat 208, and a moving seat motor 214 for driving the middle moving seat 208 is provided on the middle moving seat 208;

[0166] Specifically, when in use, the air pump 30102 is controlled by a PLC controller, and the air pump 30102 injects air into the pressure-stabilizing tank 30101. The air in the pressure-stabilizing tank 30101 enters the air inlet channel 306012 inside the metal substrate 30601 through the air supply pipe 30103, the air supply guide pipe 30104, and the air inlet branch pipe 301041 on the air supply guide pipe 30104. The air in the air inlet channel 306012 then enters the rubber expansion tube 30602 through the air outlet hole 306011 on the surface of the metal substrate 30601, so that the rubber expansion tube 30602 expands.

[0167] After the slurry electric valve 30207 is opened, the metering pump 30202 starts working to introduce the adhesive liquid in the adhesive liquid tank 30201 into the first outer cylinder 30210 through the adhesive liquid pipe 30208, the liquid collecting pipe 30209 and the adhesive liquid branch pipe 30211;

[0171] The second roller driving motor 30311 is controlled by a PLC controller. The second roller driving motor 30311 drives the bonding fiber roller 30307 to rotate through the second driving roller 30308. The non-metallic fibers in the bonding fiber roller 30307 are scooped up by the fiber disturbance paddle 30309 and attached to the adhesive liquid on the surface of the rubber expansion tube 30602.

[0172] At the same time, the piston rod of the electric cylinder 30506 extends, so that the moving ring 30507 pulls the elastic rubber ring 30509 open through the traction wire 30508, and the elastic rubber ring 30509 is in an open state;

[0180] The grabbing motor 402 works to rotate the steel fiber grabbing conveyor belt 418, so that after the grabbing electromagnet 401 is powered on, the steel fiber at the outlet slot 421 is sucked. When the steel fiber is transported to the top of the steel fiber magnetized conveyor belt 406, the corresponding grabbing electromagnet 401 is powered off, and the steel fiber falls on the steel fiber magnetized conveyor belt 406 under the action of its own gravity;

[0181] The magnetized conveyor belt motor 420 transports the steel fibers through the steel fiber magnetized conveyor belt 406. At the same time, the PLC controller controls the magnetized electromagnet to be energized, and the magnetized electromagnet magnetizes the steel fibers on the steel fiber magnetized conveyor belt 406.

[0182] The steel fiber laying motor 407 is controlled by a PLC controller. The steel fiber laying motor 407 drives the steel fiber conveying conveyor belt 411 to rotate. The PLC controller controls the laying electromagnet to generate suction to absorb the magnetized steel fibers on the steel fiber magnetizing conveyor belt 406. When the steel fibers move to the bottom of the steel fiber conveying conveyor belt 411, the corresponding laying electromagnet is powered off, so that the steel fibers fall into the forming and curing box 10 under the action of their own gravity.

[0183] Furthermore, the moving seat motor 214 drives the middle moving seat 208 and the side moving seat 209 to move forward and backward along the front and rear tracks 410 to achieve the forward and backward movement of the concrete spray pipe 204 and the spray head 503;

[0184] The laying moving motor 412 is controlled by a PLC controller, and the laying moving motor 412 drives the laying roller 413 to roll on the upper end surface of the laying guide rail 414, so that the steel fiber conveying guide rail frame 409 moves in the left and right direction, thereby realizing the left and right movement of the concrete spray pipe 204 and the spray head 503;

[0185] Thus, the steel fibers, concrete slurry and conductive materials can be uniformly transported into the molding and curing box 10;

[0186] Then, the air pump 30102 stops working, so that the rubber expansion tube 30602 stops expanding, and the piston rod of the electric cylinder 30506 retracts. At this time, the elastic rubber ring 30509 retracts and closes to tightly fit the outside of the fiber bonding rod module 306 to prevent the concrete slurry inside the molding and curing box 10 from penetrating from the gap between the fiber bonding rod module 306 and the rubber buffer sealing tube 305.

[0187] The turntable motor 30408 ​​works to drive the fiber bonding rod module 306 to perform spiral motion, so as to separate the fiber bonding rod module 306 from the non-metallic fibers bonded to its outer side;

[0188] The sliding seat driving motor 30407 works, so that the mounting frame 30411, the rectangular plate 30409 and the fiber bonding rod module 306 move forward and reset, until the rear portion of the fiber bonding rod module 306 is separated from the inside of the molding and curing box 10;

[0189] The U-shaped frame 606 is provided with a magnetic guide electromagnet inside. After power is turned on, the U-shaped frame 606 moves backward along the two sets of front and rear slide rails 605, so that the U-shaped frame 606 moves from front to back outside the forming and curing box 10, so that the magnetic guide electromagnet after power is turned on magnetically guides the steel fibers in the forming and curing box 10, adjusts the position and posture of the steel fibers, and maximizes the bearing capacity of the component along the preset direction;

[0190] The forming and curing box 10 is driven to move to the curing position by the support wheels on the support seat 607, and the primary power supply electrode 602, the secondary power supply electrode 603 and the tertiary power supply electrode 604 are energized by the distribution box 601, so that the primary power supply electrode 602, the secondary power supply electrode 603 and the tertiary power supply electrode 604 form a conductive loop with the conductive material formed by the graphite powder and steel fiber in the forming and curing box 10, so as to heat the concrete in the forming and curing box 10, so as to complete the concrete curing work. Among them, the conductive material formed by the graphite powder and the steel fiber is evenly mixed with the concrete slurry, which can not only make the concrete heated by the primary power supply electrode 602, the secondary power supply electrode 603 and the tertiary power supply electrode 604, but also change the overall structural properties of the concrete.

[0191] The present invention uses magnetic force to control the steel fiber guiding mechanism, which basically realizes the directional and orderly distribution of steel fibers in concrete, significantly improving the effective utilization rate of fibers and the mechanical properties of concrete. At the same time, combined with the strategy of directional spraying of conductive materials (such as graphite powder), the current passes through the pole piece and the concrete containing graphite powder through the voltage difference at both ends of the box, and an artificial conductive path is constructed. A closed loop is formed to generate heat energy, and uniform and rapid maintenance of fiber concrete is achieved. The quality stability of concrete under severe cold conditions is ensured, opening up a new way for the application of fiber concrete in extreme environments.

[0192] (1) Regional mixing and spiral optimization arrangement:

[0193] The device combines a variety of fibers (such as polypropylene fibers, etc.) with steel fibers, and arranges them in a coordinated manner inside the concrete. Through spiral motion, the distribution of fibers and admixtures is optimized and the disturbance to the slurry is reduced, forming a tightly packed uniform channel structure to ensure the maximum uniform distribution within the effective volume. Secondly, there are transitional gaps in the channel structure, so that the complementary effects of each channel do not interfere with each other, achieving the prerequisite for gradient electric heating maintenance. Excessive concentration of fibers and uneven heating are avoided, thereby improving the uniformity and overall performance of concrete.

[0194] (2) Ring-shaped electromagnet guides the orderly and positive arrangement of steel fibers to strengthen concrete:

[0195] The magnetic force of the steel fibers is guided by the reciprocating work of the annular electromagnet, and the steel fibers are generally distributed in a positive direction before the initial setting of the concrete. The orderly arrangement of the steel fibers avoids the performance waste caused by the random distribution of the steel fibers in the traditional method. Under the condition of controlling the amount of linear fibers, it can ensure that each steel fiber can fully play its reinforcing role, and effectively avoid the problem of fiber blocking the machine, thereby improving the bearing capacity and stability of the concrete.

[0196] (3) Steel fiber-graphite powder composite electric heating and curing strategy:

[0197] The steel fibers are effectively guided to the predetermined locations, and the conductive materials are precisely applied using directional spraying technology to build a good conductive network, and to build and direct conductive channels inside the concrete, thereby improving the stability and reliability of the conductive layer and providing support for winter concrete construction and maintenance. Secondly, the current stimulation of multiple conductive channels accelerates the formation of the internal strength structure of the concrete, improves the early hydration effect, and greatly improves engineering efficiency.

[0198] (4) Air-drum multi-protrusion fiber attachment and slurry prevention device:

[0199] By designing a multi-protrusion air-drum fiber attachment and slurry-prevention rod device, efficient operation is achieved in the fiber and adhesive working process. The core of the device lies in its unique active protrusion structure, which can effectively increase the slurry and fiber attachment area. When the rod completes the fiber conveying work, the rubber protrusion (i.e., the protrusion generated by the air intake expansion of the rubber expansion tube 30602) can be quickly and completely retracted by adjusting the internal pressure, thereby reducing the disturbance to the concrete slurry.

[0200] (5) Steel fiber absorption and magnetization distribution strategy:

[0201] The steel fibers are extracted by magnetic force and magnetized during the conveying process. Based on the conveying speed of the conveyor belt, the magnetization effect, the release time and position, the weak guidance of the peripheral fibers by the ring magnet and the strong guidance of the internal fibers are achieved, the difference in the guiding effect of the internal and external steel fibers due to the attenuation of the magnetic field is reduced, the uniformity of the ring magnetic guidance is enhanced, and the aggregation effect is reduced. The directional arrangement and distribution of the steel fibers in a predetermined position and orientation can be achieved.

[0202] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
