[0023] In addition, the present invention also provides a construction method for a cast-in-place concrete placement intelligent system based on climbing formwork construction equipment, the steps of which are as follows:

[0024] S1: According to the needs of concrete placement construction, the height and tilt angle of the main body of the placement pipe are adjusted by the lifting module of the placement pipe. According to the concrete placement construction sequence, the i-th valve start / stop module to be opened is determined. When the placement valve drive module receives the running command signal, the axial movement unit starts and drives the longitudinal movement unit connected to it to move laterally to directly below the i-th valve start / stop module. The longitudinal movement unit starts and drives the clamping unit to move vertically to both sides of the i-th valve start / stop module. The clamping unit clamps the i-th valve start / stop module and releases the locking device of the i-th valve start / stop module. The clamping unit drives the i-th valve start / stop module to move vertically along the longitudinal movement unit and laterally along the axial movement unit in sequence, so that the sealing stop of the i-th valve start / stop module is disengaged from the i-th outlet.

[0025] S2: Start the pump pipe axial drive module. The pumped concrete is fed into the inner cavity of the main body of the placing pipe through the inlet. The spiral blades drive the concrete to rotate in a spiral and flow out from the i-th outlet of the main body of the placing pipe for pouring. After the concrete is poured, stop the pump pipe axial drive module. The placing valve drive module drives the i-th pipe valve start / stop module to move to the position of the i-th outlet. The sealing head blocks the i-th outlet and the locking device fixes it to the main body of the placing pipe.

[0026] S3: Repeat S1 and S2, and open the start / stop module of the pipe valve of the next discharge port according to the concrete placement construction sequence, and carry out the concrete placement construction in sequence.

[0027] N is a natural number, and N≥1, i=1,2,3...N.

[0028] The construction method of the intelligent system for cast-in-place concrete placement based on climbing formwork construction equipment of the present invention firstly adjusts the height and inclination angle of the main body of the placement pipe through the lifting module of the placement pipe, which is conducive to the efficient transmission and transportation of concrete slurry. Then, according to the concrete placement construction sequence, the i-th valve start / stop module to be opened is determined. The placement valve drive module drives the clamping unit to move horizontally and vertically to the position of the i-th valve start / stop module. The clamping unit clamps the i-th valve start / stop module and drives it to move to other positions. The spiral blades of the pump pipe axial drive module drive the concrete to rotate spirally and flow out from the i-th outlet of the placement pipe main body for pouring. This process is repeated to carry out concrete placement construction in sequence. Since the construction personnel can control the opening and closing of each outlet individually according to the concrete placement construction sequence and through the placement valve drive module, intelligent control of concrete placement is achieved, which improves the concrete pouring quality of super high-rise buildings.

[0056] The present invention relates to an intelligent system for cast-in-place concrete placement based on a climbing formwork construction equipment, comprising a placement pipe body 10, a pump pipe axial drive module 20, a pipe valve start / stop module 40, a pair of placement valve drive modules, and a placement pipe lifting module. Two end caps of the pump pipe axial drive module 20 are installed at both ends of the placement pipe body 10. A spiral blade 25 is disposed within the inner cavity of the placement pipe body 10 and connected to a placement axial drive motor 24. Multiple pipe valve start / stop modules 40 correspond in number and position to multiple discharge ports 14 at the bottom of the placement pipe body 10. Multi-layer sealing heads 42 of the pipe valve start / stop modules 40 tightly seal the discharge ports 14 and are secured to the placement pipe body 10 by a locking device. The placement pipe lifting module 50 is movable. Connected to both sides of the bottom of the concrete placing pipe body 10, and capable of adjusting the height and inclination angle of the concrete placing pipe body 10 according to construction needs, a pair of placing valve drive modules are symmetrically arranged on both sides of the concrete placing pipe body 10. The axial movement unit 30 of the placing valve drive module drives the clamping unit to move horizontally along the axis of the concrete placing pipe body 10, and its longitudinal movement unit 35 drives the clamping unit to move vertically, so that the clamping unit can be accurately positioned below the corresponding discharge port 14 in the area where concrete is to be placed, and clamps the pipe valve start / stop module 40 to realize the automatic opening and closing of the discharge port 14, thereby realizing the automated concrete placing construction of the entire steel platform. This intelligent system for cast-in-place concrete placing has the following beneficial effects:

[0057] 1. The cast-in-place concrete placing system has a high degree of modularity in its components, and is simple and convenient to install and disassemble. This allows the cast-in-place concrete placing system to be flexibly built according to the needs of on-site construction, improving the versatility of the placing equipment and reducing the equipment investment cost of the project.

[0058] 2. The intelligent concrete placing system's placing pipe lifting module can adjust the height and tilt angle of the placing pipe body 10 according to construction needs, improving the applicability of the placing equipment. Moreover, the equipment is small in size and easy to move, reducing construction risks and improving construction efficiency, thus having the beneficial effects of reducing labor and ensuring safety.

[0059] 3. The intelligent system for cast-in-place concrete placement is equipped with multiple discharge ports 14 and valve start / stop modules 40 with corresponding numbers and locations. Construction personnel can control the opening and closing of each discharge port 14 individually through the placement valve drive module according to the concrete placement construction sequence, thereby realizing intelligent control of concrete placement and improving the concrete pouring quality of super high-rise buildings.

The cylinder 357 is connected to the side wall of the rotating rod 356, and the telescopic rod 358 is connected to the piston of the cylinder 357. The end of the telescopic rod 358 is connected to the chuck 359. Driven by the second drive motor, the clamping unit slides vertically along the longitudinal sliding screw 351 to the designated position. The third drive motor 355 starts and drives the rotating shafts on both sides to rotate synchronously to adjust the working posture. The cylinder 357 drives the chuck 359 to extend out of the inner cavity of the rotating rod 356, clamp the i-th valve start / stop module 40 and move it to the designated position. After the concrete is placed at the location of the i-th discharge port 14, the clamping unit drives the i-th valve start / stop module 40 to return to its original position and block the discharge port 14. The cylinder 357 drives the chuck 359 to retract into the inner cavity of the rotating rod 356.

[0063] More preferably, the aforementioned transverse sliding screw 32 and longitudinal sliding screw 351 are ball screws, and the axial slide seat 353 and longitudinal slide seat 354 are detachably connected to the nuts of the ball screws. Ball screws have advantages such as high transmission efficiency and accurate positioning.

A pair of limiting brackets 45 and the rack and pinion motor 43 are arranged along a direction perpendicular to the axis of the fabric tube body 10 and are respectively fixed to the base 41. The pair of limiting brackets 45 are located on both sides of the rack and pinion motor 43. The top of the pair of limiting brackets 45 is provided with corresponding limiting holes. The first transmission rack 46 passes through the limiting holes of the pair of limiting brackets 45. The transmission gear 44 is located on the top of the rack and pinion motor 43 and connected to its main shaft. The transmission gear 44 meshes with the first transmission rack 46. The locking mechanism 47 includes a pair of fixing grooves 471, a pair of slots 474, a pair of movable switches 472, a pair of second transmission racks 473, a fixing post 475, and a first gear 476. Two gears 477, a pair of fixed grooves 471 are spaced apart along the axis of the main body 10 of the fabric tube, the fixed grooves 471 are provided with transverse through slots, a pair of slots 474 are respectively fixed to the outer wall of the outlet 14 of the main body 10 of the fabric tube, and the positions of the fixed grooves 471 and the slots 474 are corresponding, a pair of movable switches 472 respectively pass through the slots of the pair of fixed grooves 471 and can slide along the slots, the upper and lower first gears 476 and the second gears 477 are sleeved and fixed to the fixed post 475, and the fixed post 475 is vertically fixed to the base 41, the first gear 476 meshes with the first transmission rack 46, one end of the movable switch 472 is connected to a second transmission rack 473, and the other end can pass through the fixed groove 471 and be snapped into the slot 474, a pair of second transmission racks 473 are staggered on both sides of the second gear 477 and mesh with the second gear 477 respectively.

[0065] In this embodiment, to ensure the stability of the connection between the valve start / stop module 40 and the main body 10 of the fabric tube, two locking mechanisms 47 symmetrically arranged on both sides of the rack and pinion motor 43 are used. The working process of the locking device is as follows: After the multi-layer sealing head 42 of the valve start / stop module 40 is tightly sealed to the outlet 14, the rack and pinion motor 43 starts, driving the transmission rack 46 meshing with it to move laterally. The transmission rack 46 synchronously pushes the two first gears 476 meshing with it to rotate. The two second gears 477 synchronously drive the two pairs of transmission racks 473 meshing with it to move towards each other or relative to each other, so that the two pairs of movable switches 472 synchronously extend and lock into the slots 474 of the main body 10 of the fabric tube, or the two pairs of movable switches 472 synchronously retract and disengage from the slots 474.

[0066] like Figure 5 and Figure 6 As shown, the main body 10 of the concrete placing pipe is assembled from multiple standard sections 11 of the concrete placing pipe in sequence. The concrete placing distance can be set according to the construction needs. The standard section 11 of the concrete placing pipe is a hollow U-shaped pipe. The hollow pipe has the functions of being lightweight and heat-insulating.

The U-shaped chucks of two adjacent standard sections 11 of the concrete placing pipe can be tightly snapped into the U-shaped groove, thereby continuously assembling multiple standard sections 11 of the concrete placing pipe into a whole concrete placing pipe main body 10. The snap-fit ​​connection method of chuck and groove is conducive to the rapid splicing and structural sealing between adjacent standard sections 11 of the concrete placing pipe.

[0067] like Figure 4 and Figure 5 As shown, each standard section 11 of the fabric tube is provided with at least one pair of locking fasteners on both sides. Each locking fastener includes two protrusions 70, a bolt, and a nut (not shown in the figure). The two protrusions 70 are respectively fixed to the edges of two adjacent standard sections 11 of the fabric tube, and each protrusion 70 has corresponding through holes. One end of the bolt passes through the two protrusions 70 of two adjacent standard sections 11 in sequence and is then locked in place by the nut. In this embodiment, two pairs of locking fasteners are provided on both sides of each standard section 11 of the fabric tube, further improving the stability of the assembled structure of the standard section 11 of the fabric tube.

[0068] In addition, such as Figure 1 and Figure 2 As shown, the top of the main body 10 of the fabric tube is also provided with an upper cover 15 for sealing the inner cavity of the main body 10 of the fabric tube. The inlet 16 is provided on the upper cover 15 of the fabric tube and communicates with the inner cavity of the main body 10 of the fabric tube.

[0069] Please continue to refer to this. Figure 1 and Figure 2 The placing boom lifting module 50 also includes a ball joint connector 54. Both ends of the ball joint connector 54 are connected to the telescopic support leg and the end cap, respectively. The telescopic support leg is hinged to the end cap via the ball joint connector 54. Because the ball joint connector 54 has 360 degrees of rotational freedom, the tilt angle of the placing boom body 10 can be flexibly adjusted according to construction needs, and the placing boom lifting module 50 can be prevented from being damaged by bending forces, thus improving the safety of equipment operation. In this embodiment, the sliding base 51 consists of a base and four universal wheels 55 connected to its bottom, making the equipment move more quickly and improving work efficiency.

[0070] like Figure 7As shown, the helical blade 25 is composed of multiple unit segments 251 spliced ​​together end to end. The two ends of the unit segment 251 are a rectangular embedded end 252 and a grooved end 253 that matches the embedded end 252. When two adjacent unit segments 251 are assembled, the embedded end 252 of one unit segment 251 is inserted into the grooved end 253 of the adjacent unit segment 251, thereby realizing the docking and assembly of multiple unit segments 251.

[0071] Combination Figures 1 to 13 The construction method of the intelligent system for cast-in-place concrete placement based on climbing formwork construction equipment of the present invention is described in detail below:

[0072] S1: According to the needs of concrete placement construction, the height and tilt angle of the main body 10 of the placement pipe are adjusted by the lifting module 50 of the placement pipe to facilitate the transmission and transportation of concrete slurry. According to the concrete placement construction sequence, the i-th valve start / stop module 40 to be opened is determined. When the placement valve drive module receives the running command signal, the axial movement unit 30 is started, which drives the longitudinal movement unit 35 connected to it to move laterally to directly below the i-th valve start / stop module 40. The longitudinal movement unit 35 is started, which drives the clamping unit to move vertically to both sides of the i-th valve start / stop module 40. The clamping unit clamps the i-th valve start / stop module 40 and releases the locking device of the i-th valve start / stop module 40. The clamping unit drives the i-th valve start / stop module 40 to move vertically along the longitudinal movement unit 35 and laterally along the axial movement unit 30, so that the sealing stop head 42 of the i-th valve start / stop module 40 is disengaged from the i-th discharge port 14.

[0073] S2: Start the pump pipe axial transmission module 20. The pumped concrete is fed into the inner cavity of the placing pipe body 10 through the inlet 16. The spiral blade 25 drives the concrete to rotate spirally and flows out through the i-th outlet 14 of the placing pipe body 10 for pouring. After the concrete is poured, stop the pump pipe axial transmission module 20. The placing valve drive module drives the i-th pipe valve start / stop module 40 to move to the position of the i-th outlet 14. The sealing stop head 42 blocks the i-th outlet 14 and is fixed to the placing pipe body 10 by the locking device.

[0074] S3: Repeat S1 and S2, and according to the concrete placement construction sequence, open the pipe valve start / stop module 40 of the next outlet 14 to carry out the concrete placement construction in sequence.

[0075] N is a natural number, and N≥1, i=1,2,3...N.

[0076] The construction method of the intelligent system for cast-in-place concrete placement based on climbing formwork construction equipment of the present invention firstly adjusts the height and inclination angle of the main body 10 of the placement pipe through the lifting module 50, which is conducive to the efficient transmission and transportation of concrete slurry. Then, according to the concrete placement construction sequence, the i-th valve start / stop module 40 to be opened is determined. The placement valve drive module drives the clamping unit to move horizontally and vertically to the position of the i-th valve start / stop module 40. The clamping unit clamps the i-th valve start / stop module 40 and drives it to move to other positions. The spiral blades 25 of the pump pipe axial drive module 20 drive the concrete to rotate spirally and flow out from the i-th outlet 14 of the placement pipe main body 10 for pouring. This process is repeated to carry out concrete placement construction in sequence. Since the construction personnel can control the opening and closing of each outlet 14 individually according to the concrete placement construction sequence and through the placement valve drive module, intelligent control of concrete placement is realized, which improves the concrete pouring quality of super high-rise buildings.

[0077] In step S1 above, after the fabric valve drive module receives the operation command signal, the first drive motor 34 of the axial movement unit 30 starts, the transverse sliding screw 32 rotates and drives the longitudinal movement unit 35 to slide horizontally to directly below the i-th pipe valve start / stop module 40, the first drive motor 34 stops working, the second drive motor 352 starts, the longitudinal sliding screw 351 rotates and drives the clamping unit to slide vertically to be positioned on both sides of the i-th pipe valve start / stop module 40, the second drive motor 352 stops working, the third drive motor 355 starts, drives the rotating rod 356 to rotate to adjust the working posture of the clamping unit, the third drive motor 355 stops working, and the cylinder 357 extends the belt. The movable chuck 359 extends out of the inner cavity of the rotating rod 356, causing the pair of chucks 359 of the clamping unit to clamp the i-th valve start / stop module 40. The second drive motor 352 starts, driving the i-th valve start / stop module 40 to move down a certain distance and separate from the i-th discharge port 14. The second drive motor 352 stops working, and the first drive motor 34 starts, driving the longitudinal moving unit 35 to slide horizontally a certain distance, causing the i-th valve start / stop module 40 to move to another position, that is, to avoid being directly below the i-th discharge port 14. The axial moving unit 30 and the longitudinal moving unit 35 use screw transmission to realize the lateral and vertical movement of the clamping unit, which has high positioning accuracy and is stable and reliable.

[0078] like Figure 13As shown, in step S2, when the i-th valve start / stop module 40 is opened, the rack and pinion motor 43 starts, driving the transmission gear 44 to rotate counterclockwise. The transmission rack 46 meshing with the transmission gear 44 moves horizontally to the left under its push, driving the first gear 476 meshing with the transmission rack 46 to rotate counterclockwise, so that the two second gears 477 rotate counterclockwise synchronously. The pair of transmission racks 473, which are staggered on both sides of the second gear 477 and mesh with it, move synchronously relative to each other, driving the movable switch 472 to retract along the fixed groove 471 and disengage from the slot 474 of the fabric tube body 10. The i-th discharge port 14 is opened; after the concrete placement operation at the location of the i-th discharge port 14 is completed, the control valve drive module moves in reverse, so that the i-th valve start / stop module 40 is blocked at the i-th discharge port 14, the rack and pinion motor 43 is started, driving the transmission gear 44 to rotate clockwise, pushing the transmission rack 1 46 to move horizontally to the right, indirectly driving the two second gears 477 to rotate clockwise synchronously, so that a pair of transmission racks 2 473 move towards each other, driving the movable switch 472 to extend along the fixed groove 471 and lock into the slot 474 of the material placement pipe body 10, thus sealing the i-th discharge port 14.

[0079] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the scope of the claims.
