Description

[0002] Self-compacting concrete refers to concrete that can flow and compact under its own weight, completely fill the formwork even in the presence of dense steel reinforcement, achieve good homogeneity, and does not require additional vibration.

[0003] During construction, self-compacting concrete produced by the batching plant needs to be transported to the construction site for pouring using a transfer bucket. For example, during tunnel construction, the batching plant is located outside the tunnel, and the self-compacting concrete produced by the batching plant needs to be transported to the construction point inside the tunnel using a transfer bucket. However, the current transfer bucket has some problems in use. On the one hand, when pouring self-compacting concrete, ordinary transfer buckets require manual control of the amount of concrete, which is inconvenient and inefficient. On the other hand, self-compacting concrete is prone to segregation during the transfer process, affecting the construction quality. Therefore, a self-compacting concrete anti-segregation transfer and pouring device is proposed. Utility Model Content

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments, highlighting the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0034] Example:

[0035] like Figure 1-5 As shown, the present invention provides a self-compacting concrete anti-segregation transfer and grouting device, which includes a frame 10, a container 20, a mixing mechanism 30, a weight detector 40, a material blocking component 50, and a control cabinet 60.

[0036] Specifically, the frame 10 includes an upper support 11 and a lower support 12. The bottom of the container 20 is provided with a material discharge port 21. The container 20 is fixed on the upper support 11. The stirring mechanism 30 is installed on the container 20. The stirring mechanism 30 can stir the material in the container 20.

[0037] The weight detector 40 is arranged between the upper support 11 and the lower support 12 to support the upper support 11 on the lower support 12, so as to detect the weight applied by the upper support 11. The material blocking assembly 50 is used to close or open the material drop port 21. The control cabinet 60 is connected to the material blocking assembly 50 and the weight detector 40, and can control the material blocking assembly 50 and the weight detector 40 to work together.

[0038] During construction, after the mixing plant produces self-compacting concrete, it pours the self-compacting concrete into a transfer and automatic pouring device. The transfer and automatic pouring device then transports the concrete to the construction site for pouring. During pouring, the material in container 20 falls into the pouring port through the bottom discharge port 21.

[0039] The frame 10 consists of an upper support 11 and a lower support 12. The container 20 is mounted on the upper support 11. During filling, the lower support 12 is placed on a fixed structure and supports the upper support 11 via a weight detector 40. The weight of the container 20 is applied to the weight detector 40. When the weight of the material in the container 20 changes, the weight information detected by the weight detector 40 also changes accordingly. Furthermore, the weight detector 40 uploads the detected weight information to the control cabinet 60. Before discharging, the weight applied to the weight detector 40 by the upper support 11 is A. After the material is dropped, the weight applied to the weight detector 40 by the upper support 11 is B. By comparing the weight change before and after the material is dropped, the control cabinet 60 can obtain the amount of material dropped (AB) of the container 20. Therefore, the control cabinet 60 can control the material blocking component 50 to close or open the material dropping port 21 according to the detection structure of the weight detector 40, thereby realizing automated quantitative material dropping. It can conveniently and efficiently fill multiple building bodies in sequence. Especially in the scenario where a large number of identical structures need to be filled, the control cabinet 60 can control the filling with a fixed filling volume, which is convenient and efficient.

[0040] In one embodiment of this application, the bottom of the upper support 11 is provided with a plurality of support feet 111, and a weight detector 40 is arranged on each support foot 111 to support the upper support 11 on the lower support 12. Since the weight detectors 40 are connected to the control cabinet 60, the control cabinet 60 can obtain the detection results of each weight detector 40. The weight of the upper support 11 is distributed on the plurality of weight detectors 40. The control cabinet 60 can sum up the weights detected by all weight detectors 40 to obtain the total load applied by the upper support 11. Specifically, before the material is dropped, the weights detected by the weight detectors 40 corresponding to the plurality of support feet 111 are A1, ..., An, respectively, and the total weight A applied by the upper support 11 is (A1 + ... + An). After the material is dropped, the weights detected by the weight detectors 40 corresponding to the plurality of support feet 111 are B1, ..., Bn, respectively, and the total weight B applied by the upper support 11 is (B1 + ... + Bn).

[0041] Furthermore, the number of support feet 111 that can be arranged at the bottom of the upper bracket 11 can be set according to actual needs. Figure 2 In the structure shown, the bottom of the upper bracket 11 is provided with four support feet 111, and a weight detector 40 is arranged on each support foot 111.

[0042] refer to Figure 4 - Figure 6In one embodiment of this application, the material blocking assembly 50 includes a material blocking element 51 and a driving element 52. The driving element 52 can drive the material blocking element 51 to close or open the discharge port 21. Specifically, the material blocking element 51 can rotate or slide. Under the drive of the driving element 52, the material blocking element 51 can cover the discharge port 21 to prevent material from falling, or it can move away from the discharge port 21 to allow the material in the container 20 to be discharged through the discharge port 21. Furthermore, the driving stroke of the driving element 52 can be precisely controlled by the control cabinet 60, thereby controlling the area of ​​the material blocking element 51 covering the discharge port 21 to control the opening area of ​​the discharge port 21, thereby controlling the discharge speed of the discharge port 21.

[0043] Furthermore, the baffle 51 includes a rotating shaft 511, a first rotating part 512, and a second rotating part 513. The rotating shaft 511 is rotatably mounted on the container 20 and / or the upper support 11. The first rotating part 512 and the second rotating part 513 are connected to the rotating shaft 511 and cannot rotate relative to each other. The second rotating part 513 is located below the discharge port 21 and has a plate-like structure. The driving element 52 is a hydraulic cylinder, and its piston rod is connected to the first rotating part 512. When the piston rod of the hydraulic cylinder extends and retracts to drive the first rotating part 512, the second rotating part 513 closes or opens the discharge port 21.

[0044] Specifically, the first rotating part 512, the second rotating part 513 and the rotating shaft 511 cannot rotate relative to each other, and the rotating shaft 511 is rotatably mounted. Therefore, the first rotating part 512, the second rotating part 513 and the rotating shaft 511 rotate synchronously as a whole. The driving element 52 is a hydraulic cylinder, and its piston rod is connected to the first rotating part 512. When the piston rod performs a telescopic action, the first rotating part 512 moves accordingly and drives the rotating shaft 511 to rotate. The second rotating part 513 on the rotating shaft 511 also rotates accordingly. The second rotating part 513 is located below the discharge port 21 and has a plate-like structure. When the piston rod of the hydraulic cylinder telescopically drives the first rotating part 512, the second rotating part 513 can close or open the discharge port 21.

[0045] Furthermore, it should be understood that the container 20 is mounted on the upper support 11 as a single structure. In one specific technical solution, the rotating shaft 511 is only connected to the container 20. In another specific technical solution, the rotating shaft 511 is only connected to the upper support 11. In yet another specific technical solution, the rotating shaft 511 is connected to both the container 20 and the upper support 11, with both providing the installation foundation.

[0046] Furthermore, both the first rotating part 512 and the second rotating part 513 rotate around the rotation axis of the rotating shaft 511. The hydraulic cylinder indirectly drives the second rotating part 513 to rotate by driving the first rotating part 512 to rotate, and closes or opens the material discharge port 21 through the second rotating part 513. This arrangement allows the hydraulic cylinder to be as far away from the material as possible, avoiding adverse effects of the concrete material on the hydraulic cylinder. On the other hand, it can change the driving stroke of the hydraulic cylinder, thereby meeting the driving stroke requirements for closing or opening the material discharge port 21.

[0047] Continue to refer to Figure 4 - Figure 6 The material blocking assembly 50 also includes a first limiting plate 53 and a second limiting plate 54. The first limiting plate 53 and the second limiting plate 54 are fixedly installed on the container 20 and / or the upper support 11. The first limiting plate 53 is attached to the upper surface of the second rotating part 513, and the second limiting plate 54 is attached to the lower surface of the second rotating part 513. The first limiting plate 53 is combined with the discharge port 21 of the container 20 and has a first material passage hole 531. The second limiting plate 54 has a second material passage hole 541. Both the first material passage hole 531 and the second material passage hole 541 are aligned with the discharge port 21. The second rotating part 513 can cover the first material passage hole 531 or be offset from the first material passage hole 531 by rotating, thereby closing or opening the discharge port 21.

[0048] Specifically, the first limiting plate 53 and the second limiting plate 54 can be fixed to the container 20 or the upper support 11, or can be jointly fixed by the container 20 or the upper support 11. The first limiting plate 53 and the second limiting plate 54 are respectively attached to the upper and lower sides of the second rotating part 513, which can support and guide the rotation of the second rotating part 513.

[0049] Since both the first material passage hole 531 and the second material passage hole 541 are aligned with the discharge port 21, when the second rotating part 513 rotates to the position covering the first material passage hole 531, the discharge port 21 can be blocked to close the discharge port 21. When the second rotating part 513 rotates to the position offset from the first material passage hole 531, the discharge port 21 is opened, and the material in the container 20 can be discharged sequentially through the discharge port 21, the first material passage hole 531, and the second material passage hole 541.

[0050] Furthermore, the baffle assembly 50 also includes a measuring sensor 55 for measuring the extension amount of the piston rod of the hydraulic cylinder. The measuring sensor 55 is connected to the control cabinet 60 so that the control cabinet 60 can control the extension amount of the piston rod according to the measurement result of the measuring sensor 55. Here, the control cabinet 60 can precisely control the extension amount of the piston rod through the measuring sensor 55, thereby controlling the area of ​​the baffle 51 covering the discharge port 21 to control the opening area of ​​the discharge port 21, thereby controlling the discharge speed of the discharge port 21.

[0051] In this embodiment, the container 20 integrates a mixing mechanism 30, which can remix the self-compacting concrete evenly to ensure construction quality. In one embodiment of this application, the mixing mechanism 30 includes a mixing shaft 31, a motor 32, and a power supply 33. The mixing shaft 31 is provided with mixing blades 34. The drive shaft of the motor 32 is connected to the mixing shaft 31 to drive the mixing shaft 31 to rotate. The power supply 33 is used to supply power to the motor 32.

[0052] The power source 33 can be an engine or a battery to supply power to the motor 32. The drive shaft of the motor 32 drives the mixing shaft 31 to rotate, so that the mixing shaft 31 mixes the concrete material in the container 20, thereby remixing the self-compacting concrete in the container 20 evenly and ensuring the construction quality.

[0053] In one embodiment of this application, multiple stirring blades 34 are arranged spirally upward along the circumference of the stirring shaft 31, and the stirring blades 34 are arranged at an upward inclination. As the stirring shaft 31 rotates, the stirring blades 34 can drive the material at the bottom of the container 20 to move upward. This design can facilitate efficient stirring and quickly remix the self-compacting concrete in the container 20.

[0054] In one embodiment of this application, the stirring shaft 31 is further provided with a scraping structure 35. The scraping structure 35 includes a scraper 351 and an installation component 352 for fixing the scraper 351 to the stirring shaft 31. The scraper 351 is attached to the side wall of the container 20. As the stirring shaft 31 rotates, the scraper 351 can scrape off the material on the side wall of the container 20. As the stirring shaft 31 rotates, the scraper 351 can continuously scrape off the self-compacting concrete material adhering to the side wall of the container 20, preventing it from solidifying on the side wall of the container 20.

[0055] refer to Figure 8 In one embodiment of this application, a filter screen 22 is provided on the top of the container 20 to filter the material poured into the container 20. The filter screen 22 can filter out large particulate impurities in the self-compacting concrete, ensuring the construction effect of the self-compacting concrete.

[0056] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
