Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, and in particular to a concrete pouring guiding device. Background Technology

[0002] In the field of modern building construction, concrete pouring is a crucial and widely used basic operation. Its construction quality is directly related to the stability and safety of the building structure. As the scale of building projects continues to expand and the building shapes become increasingly complex, the requirements for the accuracy of concrete pouring are becoming more and more stringent.

[0003] Previously, workers often had to manually adjust the position and angle of the concrete delivery pipes to align with the pouring points at different heights and directions. This manual operation was not only inefficient and costly in terms of manpower and time, but also difficult to guarantee that each adjustment would achieve the desired precision due to the limitations of human strength and accuracy. This resulted in the concrete easily deviating from the target position during the pouring process, leading to uneven pouring, local voids, or honeycomb-like surface defects, which seriously affected the strength and durability of the building structure. In view of this, this application proposes a concrete pouring guiding device. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] This utility model provides a technical solution: such as Figure 1-5 As shown, the concrete pouring guide device includes a base plate 1. Two extension plates 4 are slidably connected to the top surface of the base plate 1. A lifting mechanism is provided on the top surface of the base plate 1, and the lifting mechanism drives the two extension plates 4 to slide up and down. A rotating shaft 11 is rotatably connected to the outer side of each of the two extension plates 4. A guide cylinder 6 is installed at the other end of the two rotating shafts 11. An angle adjustment mechanism is provided on the top surface of the base plate 1, and the angle adjustment mechanism drives the guide cylinder 6 to rotate around the rotating shaft 11. Annular airbags 16 are installed inside both ends of the guide cylinder 6. An air injection mechanism is provided on the outer side of the guide cylinder 6, and each annular airbag 16 is connected to the air injection mechanism. A lifting mechanism is provided on the outer side of the top of the guide cylinder 6.

[0024] It should be noted that after the annular airbag 16 expands through the air injection mechanism, it can clamp the pipe passing through the guide tube 6. The clamping force of the annular airbag 16 is uniform and will not affect the conveying of concrete in the pipe. Furthermore, the lifting mechanism can lift the pipe.

[0025] Furthermore, the lifting mechanism includes two telescopic sleeves 3, which are symmetrically installed on the top surface of the base plate 1. Each extension plate 4 is slidably connected in the telescopic sleeve 3 corresponding to its position. Multiple first electric telescopic rods 7 are symmetrically installed on the bottom wall of each telescopic sleeve 3, and the top of each first electric telescopic rod 7 is fixedly connected to the bottom surface of the corresponding extension plate 4. The telescopic sleeves 3 can guide and limit the extension plate 4, thereby maintaining the sliding stability of the extension plate 4.

[0026] Furthermore, the angle adjustment mechanism includes a fixed plate 8, and the two ends of the fixed plate 8 are respectively fixedly installed on the outside of the two telescopic sleeves 3. The top surface of the fixed plate 8 is rotatably connected to a second electric telescopic rod 9, and the other end of the second electric telescopic rod 9 is rotatably connected to the outside of the guide cylinder 6. By extending and retracting the second electric telescopic rod 9, the guide cylinder 6 can be pulled to rotate around the pivot 11.

[0027] Furthermore, the air injection mechanism includes an air injection cylinder 10, which is fixedly installed on the outside of the guide cylinder 6. A third electric telescopic rod 12 is fixedly installed on the top surface of the air injection cylinder 10, and a sealing piston 13 is installed at the bottom end of the third electric telescopic rod 12. The sealing piston 13 is slidably connected to the air injection cylinder 10. Each annular airbag 16 is connected to the air injection cylinder 10 through a connecting pipe 14. It should be noted that the sealing piston 13 is divided into two layers, and the space between the two layers is filled with sealing oil to improve the sealing performance between the sealing piston 13 and the air injection cylinder 10.

[0028] Furthermore, the lifting mechanism includes an inclined bracket 17, which is fixedly installed on the outside of the guide cylinder 6. An assembly seat 18 is fixedly installed on the outside of the inclined bracket 17. A support plate 19 is installed on the top surface of the assembly seat 18 through multiple spring telescopic rods 20. When the concrete conveying pipe passes through the guide cylinder 6, the support plate 19 can lift the pipe under the elastic support of the spring telescopic rods 20, effectively reducing the sag of the pipe and ensuring the smoothness of concrete conveying.

[0029] Furthermore, two fixing rings 15 are fixedly installed inside both ends of the guide tube 6, and each pair of fixing rings 15 is located on the two outer sides of the corresponding annular airbag 16. The function of the fixing rings 15 is to limit the expansion position of the annular airbag 16 and ensure the stability and reliability of the clamping effect of the annular airbag 16 on the pipeline.

[0030] Furthermore, multiple support legs 2 are symmetrically installed on the bottom surface of the base plate 1, and a power supply device 5 is installed on the top surface of the base plate 1 to provide power to the device.

[0031] This utility model provides a concrete pouring guide device, the specific working principle of which is as follows: the device is moved to the concrete pouring construction position, ensuring that the support leg 2 is in stable contact with the ground to provide stable support for the device, and the power supply device 5 is connected to the external power supply to complete the power-on preparation of the device.

[0032] First, the concrete delivery pipe is passed through the guide cylinder 6. At this time, the third electric telescopic rod 12 in the air injection mechanism is activated. The third electric telescopic rod 12 pushes the sealing piston 13 to move downward in the air injection cylinder 10. The air in the air injection cylinder 10 is injected into the annular airbag 16 through the connecting pipe 14. The annular airbag 16 gradually expands and evenly clamps the pipe to ensure that the pipe is stable in position in the guide cylinder 6 and will not shake or shift due to the impact force or its own weight during the concrete delivery process, thus ensuring that the concrete can be delivered smoothly and stably through the pipe.

[0033] According to the height requirements of the concrete pouring point, the first electric telescopic rod 7 in the lifting mechanism is activated. The first electric telescopic rod 7 extends or retracts according to the preset instructions, which drives the extension plate 4 connected to it to slide up or down in the telescopic sleeve 3.

[0034] Since the guide tube 6 is installed on the rotating shaft 11 on the outside of the extension plate 4, the lifting and lowering of the extension plate 4 will synchronously drive the guide tube 6 to the designated height position, thus completing the vertical height adjustment of the device.

[0035] Once the height of the guide cylinder 6 is adjusted to the correct position, the second electric telescopic rod 9 in the angle adjustment mechanism is activated according to the actual angle requirements of concrete pouring. The second electric telescopic rod 9 begins to extend and retract, changing the angle between the guide cylinder 6 and the fixed plate 8, thereby causing the guide cylinder 6 to rotate around the rotating shaft 11. By precisely controlling the extension and retraction of the second electric telescopic rod 9, the guide cylinder 6 can be adjusted to a position that meets the angle requirements of concrete pouring.

[0036] Meanwhile, during the concrete pouring process, the support plate 19, under the elastic support of the spring telescopic rod 20, plays a supporting and buffering role for the concrete conveying pipe passing through the guide tube 6, reducing the degree of pipe sagging, preventing excessive bending of the pipe from affecting the concrete conveying, and avoiding damage to the pipe, thus ensuring the continuous and smooth progress of the concrete pouring work.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
