DETAILED DESCRIPTION

[0032] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0033] Please refer to Figures 1-9 The present application provides a technical solution: a concrete pouring device for composite thermal insulation formwork construction, comprising a pouring mechanism 10, a feeding pipe mechanism 20, an air pump 30 and a controller.

[0034] The air pump 30 can inject air or extract air into the cavity between the inner feeding pipe 21 and the outer protective pipe 22.

[0035] The feeding pipe mechanism 20 comprises an inner feeding pipe 21 and an outer protective pipe 22. The inner feeding pipe 21 is used for conveying concrete. The outer protective pipe 22 is fixedly installed outside the inner feeding pipe 21. A cavity for injecting air is arranged between the inner feeding pipe 21 and the outer protective pipe 22. The top end of the inner feeding pipe 21 is fixedly connected with a rubber hose 23. The rubber hose 23 can be bent at will, which facilitates the adjustment of the inclination angle of the inner feeding pipe 21. The bottom end of the inner feeding pipe 21 is fixedly installed with a discharging pipe 25. A plurality of speed reduction assemblies 26 for changing the flow rate of concrete are arranged inside the inner feeding pipe 21. The plurality of speed reduction assemblies 26 are spirally distributed inside the inner feeding pipe 21. An inclination sensor 29 is fixedly installed on the outer wall surface of the inner feeding pipe 21 outside the outer protective pipe 22. The model of the inclination sensor 29 is PT124B-WXQJ. The inclination sensor 29 is used for detecting the inclination angle of the inner feeding pipe 21 and transmitting the detected signal to the controller. The controller controls the air pump 30 to inject air or extract air after processing and analysis, so as to adjust the inclination angle of the speed reduction plate 261.

[0036] The feeding pipe mechanism 20 is arranged at one end of the pouring mechanism 10. The air pump 30 is arranged at the end of the pouring mechanism 10 away from the feeding pipe mechanism 20. The controller is electrically connected between the inclination sensor 29 and the air pump 30.

[0037] In the preferred technical scheme of the embodiment, the speed reducer assembly 26 comprises a mounting seat 266 fixedly installed on the inner wall surface of the inner conveying pipe 21, a rotating shaft 267 rotatably installed inside the mounting seat 266, and a speed reducer plate 261 fixedly installed at one end of the rotating shaft 267. An adjusting assembly 262 for adjusting the inclination angle of the speed reducer plate 261 is arranged at the bottom end of the speed reducer plate 261. The adjusting assembly 262 comprises a piston cylinder 2621 fixedly installed on the outer wall surface of the inner conveying pipe 21, an air inlet 2627 fixedly connected to one end of the piston cylinder 2621, and a piston plate 2626 slidably installed inside the piston cylinder 2621. A piston rod 2622 and a spring 2625 are fixedly installed at one end of the piston plate 2626. The spring 2625 is sleeved outside the piston rod 2622. One end of the piston rod 2622 penetrates through the piston cylinder 2621 and extends into the inner conveying pipe 21. A first hinged seat 2623 is fixedly installed at the bottom end of the speed reducer plate 261. A connecting sleeve 2624 is rotatably installed inside the first hinged seat 2623. The connecting sleeve 2624 is arranged at the end of the piston rod 2622 away from the piston cylinder 2621.

[0038] Further, the concrete enters the inner conveying pipe 21 through the rubber hose 23. At this time, the inclination sensor 29 detects the inclination angle of the inner conveying pipe 21 and transmits the detected signal to the controller. If the inclination angle of the inner conveying pipe 21 is small (at this time, it is in a vertical state), the controller will control the air pump 30 to inject air into the cavity between the inner conveying pipe 21 and the outer protective pipe 22. After the air enters the cavity, it enters the piston cylinder 2621 from each air inlet 2627. The air can push the piston plate 2626 to move, so as to push the piston rod 2622 outward and compress the spring 2625. When the piston rod 2626 is pushed outward, one end of the piston rod 2622 pushes the speed reducer plate 261 to overturn upward, so that the speed reducer plate 261 is in a horizontal state. When more air is injected, the inclination angle of the speed reducer plate 261 tends to be horizontal, which can increase the contact area of the concrete and the speed reducer plate 261 and make the concrete falling on the speed reducer plate 261 difficult to slide downward quickly, thereby greatly reducing the flow rate of the concrete and avoiding the segregation of the concrete. When the inclination angle of the inner conveying pipe 21 is large, the air pump 30 will extract the air in the cavity. At this time, the air in the piston cylinder 2621 will also be less. The piston rod 2622 will be recovered into the piston cylinder 2621 under the elastic force of the spring 2625, so as to pull the speed reducer plate 261 to overturn downward, so that the inclination angle of the speed reducer plate 261 is small, which can reduce the contact area of the concrete and the speed reducer plate 261, so as not to greatly affect the flow rate of the concrete when the inner conveying pipe 21 is inclined, thereby achieving dynamic speed reduction of the concrete.

[0039] It should be noted that since the inner feeding pipe 21 is controlled and poured by workers, the inclination angle of the inner feeding pipe 21 is constantly changing, so the inclination angle of the deceleration plate 261 can be adjusted in real time according to the inclination angle of the inner feeding pipe 21, which can ensure that the flow rate of the concrete is not affected while the concrete is decelerated, and the inclination angle of the deceleration plate 261 is controlled by the air pump 30 to inject or extract air to change the air pressure in the cavity.

[0040] Further expansion, when the inner feeding pipe 21 is in a vertical state, the deceleration plate 261 tends to be in a horizontal state, and when the inner feeding pipe 21 is in a horizontal state, the deceleration plate 261 tends to be in a vertical state.

[0041] In the preferred technical solution of the embodiment, the second hinge seat 263 is fixedly installed on both sides of the bottom end of the deceleration plate 261, the hinge rod 264 is rotatably installed in the second hinge seat 263, the hinge rod 264 is connected by two supporting rods, and the two supporting rods are connected by a rotating shaft and can rotate, the third hinge seat 265 is rotatably installed on one end of the hinge rod 264 away from the second hinge seat 263, and the third hinge seat 265 is fixedly installed on the inner wall surface of the inner feeding pipe 21. When the angle of the deceleration plate 261 changes, the hinge rod 264 will also bend or stretch, which can improve the stability of the deceleration plate 261.

[0042] In the preferred technical solution of the embodiment, the guide plate 211 is fixedly installed on the outer wall surface of the inner feeding pipe 21, and a plurality of air holes 213 are formed in the surface of the guide plate 211. The gas injected by the air pump 30 enters the cavity through the air nozzle 27 and moves downward through the air holes 213. The air holes 213 can ensure that the gas moves downward uniformly and ensure the uniformity of the gas in each piston cylinder 2621.

[0043] In the preferred technical solution of the embodiment, the heating wire 212 is fixedly installed on the outer wall surface of the inner feeding pipe 21 above the guide plate 211 by a supporting plate, and the heating wire 212 is electrically connected with the controller. The heating wire 212 can heat the air, increase the temperature of the air entering the cavity, and heat the inner feeding pipe 21. Therefore, when used in a low-temperature environment, the heating wire 212 can be turned on to heat the air, which can conduct heat to the inner feeding pipe 21, avoid the water in the concrete from freezing on the inner wall of the inner feeding pipe 21 due to low temperature, and ensure the smoothness of the concrete pouring in winter.
