Description

Technical Field

[0001] The invention belongs to the field of concrete pouring, and more specifically, relates to a construction method for a concrete continuous pouring bottom plate. Background Art

[0002] Nowadays, in the pouring construction of large-volume concrete base slabs, one or two pump trucks can only pour at one location at the same time. The concrete flowing out of the discharge pipe of the pump truck spreads to the surroundings in a cone shape. As the pouring time increases, the pouring location will be higher in the middle and lower around, resulting in different pouring heights at different locations, affecting the pouring quality.

[0003] If during the above process, the feed pipe is moved around the pouring site, thereby avoiding different pouring heights, this method will result in unequal pouring times at various locations, and the solidification time of concrete at different locations will deviate. If the deviation is too large, it will cause cracks in the solidified concrete. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a construction method for continuous concrete pouring of a base plate, which can realize pouring at multiple positions at the same time and can adjust the pouring flow rate at each position.

[0005] A construction method for a continuous concrete pouring base plate of the present invention comprises the following steps:

[0006] S1. The pump truck moves to the designated position, the boom system starts working, and the discharge pipe moves to the pouring site.

[0007] S2. The discharging mechanism works to adjust the distance between two adjacent discharging pipes and the position of each sealing plate so that the sealing plate at the designated position is in a half-open state.

[0008] S3. The tank truck enters the site and transports the concrete into the pump truck.

[0009] S4. The pumping system works, and concrete is discharged from the discharge pipe at the designated position. Multiple discharge pipes simultaneously pour concrete to the pouring site.

[0010] S5. The boom system works to move the discharge pipe to perform inclined layered push-type pouring.

[0011] S6. According to the actual concrete height, the position of the sealing plate is adjusted, thereby changing the flow rate of the material discharge from the discharge pipe, so that the actual height of the concrete at each position is roughly the same.

[0012] S7. After pouring, clean the pumping system.

[0013] As a further improvement of the present invention, the concrete pouring is performed by paving in multiple layers; each layer of paving does not exceed 50 centimeters.

[0014] As a further improvement of the present invention, the inclined layered push-type casting adopts a slope of 1:6 and a step width of 2-3 meters.

[0015] As a further improvement of the present invention, the discharging mechanism includes a material distribution seat connected to the pumping system, and a plurality of material distribution components evenly installed on the material distribution seat along the circumferential direction; a plurality of material distribution ports are evenly arranged along the circumferential direction in the material distribution seat; the material distribution component includes a sealing plate that is sealed and slidably connected to the material distribution seat along the radial direction of the material distribution seat and is used to change the opening size of the material distribution port.

[0016] As a further improvement of the present invention, the upper end of the inner wall of each of the material distribution openings is a material distribution slope in the shape of an inverted cone.

[0017] As a further improvement of the present invention, a rotating plate is rotatably connected below the material distribution seat; the rotating axis of the rotating plate is arranged in the horizontal direction; a plurality of the material discharge pipes are rotatably connected on the rotating plate; the rotating axis of the material discharge pipes is parallel to the rotating plate; the material discharge pipes are arranged at equal intervals; and one material discharge pipe is connected to one material distribution port.

[0018] As a further improvement of the present invention, a driven plate arranged parallel to the rotating plate is rotatably connected directly below the rotating plate; each feeding tube is arranged vertically, and the lower part of each feeding tube is rotatably connected to the driven plate.

[0019] As a further improvement of the present invention, the material distribution assembly also includes a screw rotatably connected to the material distribution seat for driving the sealing plate to slide, and a screw drive ring rotatably connected to the material distribution seat for driving each screw to rotate; the rotating shaft of the screw is arranged along the radial direction of the material distribution seat; the screw drive ring is coaxially arranged with the material distribution seat.

[0020] One end of the screw rod close to the screw rod driving ring is slidably connected along the axial direction of the screw rod with a screw rod gear which can be transmission-connected with the screw rod driving ring; the screw rod gear rotates synchronously with the screw rod in the circumferential direction.

[0021] As a further improvement of the present invention, a one-way ring is coaxially rotatably connected to the material distribution seat; an outer convex ring for driving the screw gear to separate from the screw driving ring is circumferentially arranged on the outer wall of the one-way ring.

[0022] The outer convex ring is provided with an inner groove for drivingly connecting the screw gear and the screw driving ring; when one screw gear is matched with the inner groove, the screw gear is drivingly connected to the screw driving ring, and the remaining screw gears are separated from the screw driving ring.

[0023] As a further improvement of the present invention, a positioning ring is fixedly connected to the outer wall of the material distribution seat; a ratchet ring is coaxially arranged on the outer periphery of the positioning ring; and a ratchet pawl is fixedly connected to the lower inner periphery of the one-way ring, which cooperates with the ratchet ring to prevent the one-way ring from rotating in the opposite direction.

[0024] The upper end of the positioning ring is rotatably connected to a driving gear ring coaxially arranged with the one-way ring; the side wall of the one-way ring is provided with an inclined driving bevel groove; the outer wall of the driving gear ring is provided with a sliding column that is slidably connected to the driving bevel groove to drive the one-way ring to move longitudinally.

[0025] When the driving gear ring rotates in the reverse direction, the ratchet ring prevents the one-way ring from rotating in the reverse direction, and then the driving gear ring drives the sliding column to move in the reverse direction in the driving inclined groove, forcing the one-way ring to move upward, and each screw gear is meshed with the end gear.

[0026] When the driving gear ring rotates forward, the ratchet ring does not hinder the one-way ring from rotating forward, the sliding column moves forward in the driving inclined groove, the one-way ring moves downward first under the action of its own gravity, the screw gear and the end gear are separated, and then the driving gear ring continues to rotate forward, and then the one-way ring and the driving gear rotate forward synchronously.

[0027] As a further improvement of the present invention, the outer wall of the screw is provided with a spirally arranged thread groove; both ends of the thread groove are respectively provided with guide grooves distributed along the circumference of the screw and inclined excessively with the outer wall of the screw.

[0028] A screw connection seat is provided at the upper end of the sealing plate and is slidably connected to the screw; a latch that can be slidably connected to the thread groove is longitudinally slidably connected in the screw connection seat; a latch spring that drives the latch to move in the direction of the screw is installed between the latch and the screw connection seat.

[0030] The positioning assembly includes a sliding plate which is radially connected to the distribution seat and is used to drive the pin to move longitudinally. The sliding plate is provided with a sliding stop plate which is arranged circumferentially along the distribution seat. A limiting plate is provided on the sliding plate on one side of the sliding stop plate. The outer peripheral side wall of the sliding stop plate on one sliding plate abuts against the inner peripheral side wall of the limiting plate on the previous sliding plate, thereby preventing the previous sliding plate from moving inward.

[0031] A concrete continuous casting base plate, the base plate is composed of multiple layers of paving materials; each layer of paving materials has multiple casting locations; the number of casting locations is 2-6; the distance between two adjacent casting locations is between 50-150 centimeters.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows: the present solution can carry out large-volume pouring, and by controlling the operation of the discharging mechanism and the movement of the arm system, the down pipe can be used for large-area pouring, and the present solution can synchronously pour different pouring locations at the same time, avoiding cracking of the solidified concrete due to deviations in the pouring time.

[0033] This solution changes the opening size of the material distribution port by controlling the movement of the sealing plate, thereby changing the concrete flow rate of each discharge pipe, and can timely adjust the thickness of concrete at each position, thereby ensuring that the concrete thickness at each position is roughly equal.

[0034] This solution sets a one-way ring. The one-way ring rotates circumferentially, so that the screw driving ring can drive a certain screw to rotate, and the position of the sealing plate can be adjusted to control the flow of a certain feeding pipe. The one-way ring moves longitudinally, so that the screw driving ring can drive all the screws to rotate together, and all the sealing plates can be adjusted synchronously, so as to control each sealing plate to move to a closed feeding port, an open feeding port, and a half-open state.

[0035] This solution controls the positive and negative rotation of the driving gear ring so that the driving gear ring can not only drive the one-way ring to rotate, but also drive the one-way ring to move longitudinally.

[0036] In this solution, by providing a positioning component, the sliding plate can control the movement of the latch pin, thereby making the corresponding sealing plate no longer driven by the screw rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] The inclined layered push-type casting adopts a slope of 1:6 and a step width of 2-3 meters.

[0059] The discharging mechanism A includes a distribution seat 31 connected to the pumping system 12, and a plurality of distribution components 4 evenly installed on the distribution seat 31 along the circumferential direction; a plurality of distribution ports 314 are evenly arranged along the circumferential direction in the distribution seat 31; the distribution component 4 includes the sealing plate 43 sealed and slidably connected to the distribution seat 31 along the radial direction of the distribution seat 31 and used to change the opening size of the distribution port 314.

[0061] The upper end of the inner wall of each of the material distribution openings 314 is an inverted cone-shaped material distribution slope 3141, which facilitates the concrete to enter the material distribution opening 314 and has the effect of gathering the concrete.

[0062] A rotating plate 21 is rotatably connected to the lower part of the material distribution seat 31; the rotating axis of the rotating plate 21 is arranged in the horizontal direction; a plurality of the material discharge pipes 23 are rotatably connected to the rotating plate 21; the rotating axis of the material discharge pipes is parallel to the rotating plate; each material discharge pipe 23 is arranged at equal intervals; one material discharge pipe 23 is connected to one material distribution port 314.

[0063] The number of the feed pipes 23 is equal to the number of the feed outlets 314 .

[0064] A distribution plate 33 is fixedly connected below the distribution seat 31; a plurality of closing plates 331 are evenly arranged along the circumferential direction on the outer periphery of the distribution plate 33; a closing plate 331 is fixedly connected to the lower end of a sealing seat 312; a discharge pipe 332 is respectively arranged at the lower end of the distribution plate 33, directly below each distribution port 314; a discharge pipe 332 is connected to a discharge pipe 23 through a bellows 25.

[0065] A driven plate 22 arranged parallel to the rotating plate 21 is rotatably connected directly below the rotating plate 21 ; each feeding tube 23 is vertically arranged, and the lower part of each feeding tube 23 is rotatably connected to the driven plate.

[0066] The driven plate 22 , the rotating plate 21 , and each feeding tube 23 together form a parallelogram structure, so when the rotating plate 21 rotates, the feeding tube 23 is always vertically arranged, and the distance between two adjacent feeding tubes 23 changes.

[0067] The outer wall of the feed tube 23 is fixedly connected to two longitudinally arranged feed tube rotating seats 231 ; the outer wall of the feed tube rotating seat 231 is provided with a feed tube connecting column 232 ; one feed tube connecting column 232 is rotatably connected to the rotating plate 21 , and the other feed tube connecting column 232 is rotatably connected to the driven plate 22 .

[0068] A longitudinally arranged feed pipe connecting plate 333 is fixedly connected to the center of the lower end of the material distribution plate 33 ; the rotating plate 21 and the driven plate 22 are rotatably connected to the feed pipe connecting plate 333 .

[0069] The feeding tube connecting plate 333 is fixedly connected with a feeding tube motor 24 for driving the rotating plate 21 to rotate; the output shaft of the feeding tube motor 24 is connected to the rotating plate 21 via a reduction gear set, thereby increasing the torque output by the feeding tube motor 24 .

[0070] The material distribution component 4 also includes a screw 44 rotatably connected to the material distribution seat 31 for driving the sealing plate 43 to slide, and a screw drive ring 41 rotatably connected to the material distribution seat 31 for driving each screw 44 to rotate; the rotating shaft of the screw 44 is arranged along the radial direction of the material distribution seat 31; the screw drive ring 41 is coaxially arranged with the material distribution seat 31.

[0071] One end of the screw 44 close to the screw driving ring 41 is connected to a screw gear 47 that can be transmission-connected to the screw driving ring 41 in an axially sliding manner along the screw 44; the screw gear 47 rotates synchronously with the screw 44 in the circumferential direction; a connecting shaft 443 with a non-circular cross-section is coaxially arranged at one end of the screw 44; a gear connecting hole that is slidably connected to the connecting shaft 443 is arranged in the center of the screw gear 47, so that the screw gear 47 rotates synchronously with the screw 44 in the circumferential direction and slides relatively in the axial direction.

[0072] A driving ring motor 42 for driving the screw driving ring 41 to rotate is fixedly connected to the material distribution seat 31; a driving ring gear 412 is coaxially arranged at the lower part of the screw driving ring 41; a driving ring connecting gear meshing and transmission connected with the driving ring gear 412 is fixedly connected to the output shaft of the driving ring motor 42.

[0073] An end face gear 411 capable of meshing with the screw gear 47 is coaxially arranged on the upper portion of the outer wall of the screw driving ring 41 .

[0074] A one-way ring 51 is coaxially rotatably connected to the material distribution seat 31 ; an outer convex ring 512 for driving the screw gear 47 to separate from the screw driving ring 41 is circumferentially provided on the outer wall of the one-way ring 51 .

[0075] The outer convex ring 512 is provided with an inner groove 513 for transmission connection between the screw gear 47 and the screw driving ring 41; when one screw gear 47 is matched with the inner groove 513, the screw gear 47 is transmission connected to the screw driving ring 41, and the remaining screw gears 47 are separated from the screw driving ring 41.

[0076] Transition slopes connected to the outer convex ring 512 are respectively arranged on both sides of the inner groove 513 .

[0077] The material distribution component 4 also includes a gear moving plate 48 connected to the material distribution seat 31 along the axial sliding of the screw 44 for driving the screw gear 47 to move axially; a moving plate spring 49 is installed between the gear moving plate 48 and the sealing seat 312 to drive the gear moving plate 48 to move closer to the one-way ring 51.

[0078] The upper end of the sealing seat 312 is provided with a screw rotating seat 313 which is rotatably connected to the screw 44 .

[0079] The gear moving plate 48 is abutted against the outer convex ring 512 under the action of the moving plate spring 49, and the screw gear 47 is not meshed with the end face gear 411 at this time; when the one-way ring 51 rotates to be horizontally opposite to a gear moving plate 48, the moving plate spring 49 causes the gear moving plate 48 to move toward the one-way ring 51, and finally the gear moving plate 48 moves to the inside of the inner groove 513, and a corresponding screw gear 47 meshes with the end face gear 411. At this time, the screw drive ring 41 rotates, only driving the screw gear 47 to rotate, and then only one sealing plate 43 will move, thereby changing the opening size of the material distribution port 314 at this position.

[0080] The outer wall of the material distribution seat 31 is fixedly connected with a positioning ring 32; the outer periphery of the positioning ring is coaxially provided with a ratchet ring 321; the lower inner periphery of the one-way ring 51 is fixedly connected with a pawl 515 which cooperates with the ratchet ring 321 to prevent the one-way ring 51 from rotating in the reverse direction; the pawl 515 is made of elastic material.

[0081] The upper end of the positioning ring 32 is rotatably connected to a driving ring gear 52 coaxially arranged with the one-way ring 51; the side wall of the one-way ring 51 is provided with an inclined driving inclined groove 511; the outer wall of the driving ring gear 52 is provided with a sliding column 521 which is slidably connected with the driving inclined groove 511 and thus drives the one-way ring 51 to move longitudinally;

[0082] The lower end of the outer wall of the outer convex ring 512 is provided with an inclined downward pressing slope 541 ; the upper end of the gear moving plate 48 is provided with an inclined moving plate slope 481 that matches the downward pressing slope 541 .

[0083] When the driving gear ring 52 rotates in the reverse direction, the ratchet ring 321 prevents the one-way ring 51 from rotating in the reverse direction, and then the driving gear ring 52 drives the sliding column 521 to move in the reverse direction in the driving inclined groove 511, forcing the one-way ring 51 to move upward, and the outer convex ring 512 moves upward relative to each gear moving plate 48, and finally the outer convex ring 512 moves to the top of each gear moving plate 48, and then each gear moving plate 48 moves to each screw gear 47 under the action of the moving plate spring 49, and then each screw gear 47 is meshed with the end face gear 411, and then the rotation of the screw driving ring 41 will drive each screw 41 to rotate synchronously, and each sealing plate 43 moves synchronously.

[0084] When the driving gear ring 52 rotates forward, the ratchet ring 321 does not hinder the forward rotation of the one-way ring 51, and the sliding column 521 moves forward in the driving inclined groove 511. The one-way ring 51 moves downward first under the action of its own gravity, and then the downward pressing inclined surface 541 contacts the moving plate inclined surface 481 and forces the moving plate inclined surface 481 to slide, so that the gear moving plate 48 moves away from the one-way ring 51. Finally, the sliding column 521 moves to the positive limit position in the driving inclined groove 511, and the gear moving plate 48 moves until the screw gear 47 is separated from the end face gear 411. Then the driving gear ring 52 continues to rotate forward, and the sliding column 521 will drive the driving inclined groove 511 to rotate together, and then the one-way ring 51 and the driving gear 52 rotate forward synchronously, and the inner groove 513 cooperates with each gear moving plate 48 in turn.

[0085] The upper end of the positioning ring 32 is fixedly connected to a ring gear motor 53 for driving the driving ring gear 52 to rotate; the output shaft of the ring gear motor 53 is fixedly connected to a ring gear gear meshing with the driving ring gear 52 .

[0086] The outer wall of the screw rod 44 is provided with a spirally arranged thread groove 411; both ends of the thread groove 411 are respectively provided with guide grooves 442 distributed along the circumference of the screw rod 44 and inclined excessively with the outer wall of the screw rod 44;

[0087] The upper end of the sealing plate 43 is provided with a screw connecting seat 431 which is slidably connected to the screw 44; a pin 45 which can be slidably connected to the thread groove 411 is longitudinally slidably connected inside the screw connecting seat 431; a pin spring 46 which drives the pin 45 to move toward the screw 44 is installed between the pin 45 and the screw connecting seat 431.

[0088] When the screw 44 continues to rotate in one direction, the thread groove 411 drives the latch 45 to move in one direction (forward or reverse), and the sealing plate 43 moves with the latch 45. When the latch 45 moves to the end of the thread groove, the screw 44 continues to rotate, and the latch 45 will enter the guide groove 442 and move toward the outer wall of the screw 44 along the guide groove 442. During this process, the latch 45 will slide in the direction away from the screw 44, and the latch spring 46 will shrink. Finally, the latch 45 moves to abut against the outer wall of the screw 44. The screw 44 continues to rotate, and the latch 45 continues to move along the outer wall of the screw rod 44, and finally the screw rod 44 rotates one circle, and the latch 45 re-enters the thread groove 441, and the latch spring 46 makes the latch 45 match with the thread groove 441 again, and then the screw rod 44 continues to rotate, and the latch 45 will repeat the above process, so that although the screw rod 44 continues to rotate, the latch 45 reciprocates at the end of the thread groove 441, and the sealing plate 43 does not move. If the screw rod 44 rotates in another direction at this time, the thread groove 441 will drive the latch 45 and the sealing plate 43 to move in the other direction.

[0089] In summary, no matter how the screw rod 44 rotates, the sealing plate 43 only moves between two extreme positions, and the screw rod 44 will not be stuck and unable to rotate after the sealing plate 43 moves to the extreme position.

[0090] A plurality of positioning components 6 are installed along the circumferential direction below the material distribution seat 31 ; the number of the positioning components 6 is one less than the number of the feeding tubes 23 , and one positioning component 6 is installed below one material distribution component 4 ; and there is no positioning component 6 below one of the material distribution components 4 .

[0091] The positioning assembly 6 includes a sliding plate 63 which is connected to the lower portion of the material distribution seat 31 and is used to drive the latch 45 to move longitudinally. The sliding plate 63 is provided with a sliding stop plate 632 which is arranged circumferentially along the material distribution seat 31. A limiting plate 633 is provided on the sliding plate 63 at one side of the sliding stop plate 632. The outer peripheral side wall of the sliding stop plate 632 on one sliding plate 63 abuts against the inner peripheral side wall of the limiting plate 633 on the previous sliding plate 63, thereby preventing the previous sliding plate 63 from moving inward.

[0092] The positioning assembly 6 further includes a latch driving plate 64 slidably connected to the lower end of the closing plate 331 ; the sliding direction of the latch driving plate 64 is perpendicular to the axis of the screw rod 44 .

[0093] The lower end of the latch driving plate 64 is provided with an inclined driving plate slot 641 ; the sliding plate 63 is provided with a sliding head 631 which is slidably connected with the driving plate slot 641 and thus drives the latch driving plate 64 to slide.

[0094] The lower end of the latch 45 is provided with a latch plate 451 extending to the bottom of the material distribution plate 33; the upper end of the outer wall of the latch plate 451 is provided with an inclined latch guide wall 452; the end of the latch driving plate 64 close to the latch plate 451 is provided with an inclined latch pressing slope 642 that abuts against the latch guide wall 452.

[0095] When the sliding plate 63 moves outward, the sliding head 631 moves in the driving inclined groove 641 and forces the latch driving plate 64 to move in the direction close to the latch 45, and then the latch pressing inclined surface 642 abuts and squeezes the latch guide wall 452, so that the latch 45 moves in the direction away from the screw rod 44. Finally, the sliding plate 63 moves outward to the extreme position, the latch 45 is separated from the threaded groove 441, and the screw rod 44 no longer drives the sealing plate 43 to move.

[0096] A sliding plate tension spring is installed between each of the sliding plates 63 and the closing plate 331 to drive the sliding plate 63 to move inward.

[0097] A rotating gear ring 61 is coaxially rotatably connected below the material distribution seat 31 ; the outer wall of the rotating gear ring 61 is provided with a protrusion 611 that can abut against the sliding plate 632 and thereby drive the sliding plate 632 to move outward.

[0098] When the rotating gear ring 61 moves until the protrusion 611 contacts the sliding stop plate 632 on the first sliding plate 63 , the first sliding plate 63 is located at the outer limit position, and at this time only one latch pin 45 is separated from the thread groove 441 .

[0099] When the rotating gear ring 61 moves until the protrusion 611 contacts the sliding plate 632 on the second sliding plate 63, the second sliding plate 63 is located at the outer limit position. At this time, the limit plate 633 on the first sliding plate 63 abuts against the sliding plate 632 on the second sliding plate, and the first sliding plate 63 is also located at the outer limit position. Therefore, at this time, two latches 45 are separated from the corresponding thread grooves 441 (such as Fig.10 as shown).

[0100] When the protrusion 611 contacts the sliding plate 632 on the third sliding plate 63, the three corresponding pins 45 are separated from the corresponding threaded grooves 441; in summary, by controlling the rotation of the rotating gear ring 61, the protrusion 611 cooperates with the sliding plate 632 at different positions, thereby controlling different numbers of pins 45 to separate from the corresponding threaded grooves 411, so that the corresponding sealing plate 43 remains in the current state.

[0101] Six discharge pipes 23 are provided in this solution, and this solution also includes a remote control panel. A controller for controlling the operation of various electrical components is installed on the pump truck 1. The remote control panel communicates with the controller on the pump truck 1 through wireless signals. The remote control panel has multiple buttons, and the operator can operate various systems on the pump truck 1 through the corresponding buttons.

[0102] In the initial state, the rotating plate 21 is close to a vertical state, the distance between the two feeding pipes 23 is the smallest, and each sealing plate 43 completely closes the feeding opening 314 .

[0103] When the backing plate is poured, the pump truck 1 moves to the designated position, and then the arm system 11 works to move the discharge mechanism A to the pouring location, and then the discharge mechanism A is adjusted.

[0104] The operator predetermines the required spacing between the two feeding tubes 23, and then controls the feeding tube motor 24 to rotate through the remote control panel, so that the rotating plate 21 rotates, and the spacing between the two adjacent feeding tubes 23 increases. Finally, the rotating plate 21 rotates until the distance between the two adjacent feeding tubes 23 is the required value.

[0105] The operator predetermines the number of discharge pipes 23 that need to discharge materials. For example, four discharge pipes 23 are needed for discharge, but two discharge pipes 23 do not need to discharge materials. The operator controls the gear ring motor 62 to rotate through the remote control panel, so that the gear ring motor 62 drives the rotating gear ring 61 to rotate until the protrusion 611 contacts the sliding stop plate 632 on the second sliding plate 63, and then the first and second sliding plates 63 move to the outer limit position, and the corresponding latch drive plate 64 moves in the direction close to the latch 45, so that the latch 45 is separated from the threaded groove 441, and then the corresponding two sealing plates 43 will always remain in the state of closing the material distribution port 314, and then no concrete will flow out of the corresponding two discharge pipes 23.

[0106] Then the operator controls the ring gear motor 53 through the remote control panel, and the ring gear motor 53 drives the driving ring gear 52 to rotate in the opposite direction by a certain angle. At this time, the one-way ring 51 is blocked by the ratchet ring 321 and cannot rotate, so the sliding column 521 moves in the opposite direction along the driving inclined groove 511, and the one-way ring 51 moves upward until the outer convex ring 512 is separated from each gear moving plate 48, and each moving plate spring 49 will push the gear moving plate 48 to move until each screw gear 47 is engaged with the end face gear 411.

[0107] Then, the drive ring motor 42 is controlled to drive the screw drive ring 41 to rotate a certain angle, and the screw drive ring 41 drives all the screws 44 to rotate together. However, since two pins 45 are separated from the thread groove 411, the corresponding sealing plates 43 will not move, and the remaining four pins 45 are located in the thread groove 411, and then the corresponding four sealing plates 43 will move a certain distance away from the distribution seat 31, and finally the four sealing plates 43 will close half of the corresponding distribution port 314, and then the sealing plates 43 move to a half-open state. At this time, the concrete can be discharged from the corresponding four discharge pipes 23 through the distribution port 314.

[0108] The tank truck enters the site and delivers concrete to the pump truck 1; the pumping system 12 works, delivering the concrete into the material distribution seat 31 through the feed pipe 311, and into the corresponding discharge pipe 322 through the four opened material distribution ports 314, and falls to the pouring site through the bellows 25 and the discharge pipe 23.

[0109] As the pouring time changes, the volumes of concrete flowing out of the four feeding pipes 23 are inevitably different, which makes the thickness of concrete under each feeding pipe 23 different. Therefore, it is necessary to adjust the flow rate of a feeding pipe 23 at this time. The specific operation is as follows:

[0110] The gear ring motor 53 is controlled by the remote control panel to drive the driving gear ring 52 to rotate forward, and the one-way ring 51 moves downward first, forcing each gear moving plate 48 to contact the outer convex ring 512, and then each screw gear 47 is separated from the end gear 411, and then the driving gear ring 52 continues to rotate, and the driving gear ring 52 drives the one-way ring 51 to rotate forward synchronously, so that the inner groove 513 moves to face the gear moving plate 48 corresponding to the discharge pipe 23 to be adjusted, so that the gear moving plate 48 moves into the inner groove 513, and the screw gear 47 at this position is aligned with the end gear 411. 11 meshes; then the drive ring motor 42 is controlled to drive the screw drive ring 41 to move forward or reversely. If it is necessary to increase the flow rate of the current discharge pipe 23, the screw drive ring 41 drives the screw 44 to rotate, so that the sealing plate 43 moves outward, and then the opening of the feed outlet 314 at this position is increased, so that more concrete passes through the feed outlet, thereby increasing the flow rate of the current discharge pipe 23; if it is necessary to reduce the flow rate of the current discharge pipe 23, the sealing plate 43 is controlled to move inward, and then the opening of the feed outlet 314 at this position is reduced, and the flow rate of concrete is reduced.

[0111] According to the current pouring situation, the flow rate of each discharge pipe 23 is adjusted in time so that the thickness of concrete at each position is roughly equal.

[0112] At the same time, the arm system 11 works to move the position of the discharge pipe 23 to perform inclined layered push-type pouring.

[0113] The above steps are repeated many times to carry out multi-layer paving; the formed multi-layer paving together constitutes a large-volume base plate.

[0114] After pouring is completed, the pumping system is cleaned; the gear ring motor 53 is controlled to drive the drive gear ring 52 to rotate in the opposite direction by a certain angle, and the one-way ring 51 moves upward to the outer convex ring 512 and separates from each gear moving plate 48, and each moving plate spring 49 will push the gear moving plate 48 to move until each screw gear 47 is engaged with the end face gear 411, and then the drive ring motor 42 drives the screw drive ring 41 to rotate, and each screw 44 rotates synchronously, so that the corresponding four sealing plates 43 move outward to the extreme position, the feed opening 314 opens to the maximum, and the screw 44 continues to rotate, and the pin 45 bounces back and forth between the guide groove 442 and the outer wall of the screw 44, and the sealing plate 43 no longer moves. After the set time, the drive ring motor 42 stops working. The time length of this process is equal to the time length of the sealing plate 43 moving from the position of completely closing the feed opening 314 to the position of completely opening the feed opening 314, ensuring that each sealing plate 43 can move to the outer extreme position.

[0115] Then, mortar is added into the pump truck 1, and the pumping system starts working to draw the mortar into the pumping system and finally discharge it from the discharge pipe 23. In this process, the mortar brings out the concrete attached to the inside of the pumping system, thereby completing the cleaning.

[0116] Then, the four sealing plates 43 are controlled to move to the inner limit position to close the material distribution port 314, and the feed pipe motor 24 is operated to drive the rotating plate 21 to move to a nearly vertical state, and the arm system 11 is retracted to return to the initial state.

The number of casting locations corresponds to the number of discharge pipes 23 where concrete is dropped; the distance between two adjacent casting locations corresponds to the distance between two adjacent discharge pipes 23.
