However, most existing guide pipes in actual construction use simple clamping or welding for fixation, which is difficult to adapt to guide pipes of different diameters. When the guide pipe diameter changes, the clamping stability varies significantly, making it difficult to guarantee construction quality. Utility Model Content

[0022] During construction, when concrete is pumped through a duct, the duct shakes as the concrete is pumped in and out, resulting in unstable concrete output and affecting construction quality. Existing clamping devices are difficult to adapt to ducts of different diameters, which complicates the assurance of construction quality.
[0023] This utility model proposes a fixing device 200. Figures 1 to 2 This is one embodiment of the present utility model.
[0024] In this embodiment of the present invention, the fixing device 200 includes at least two clamping components 1 and at least two driving components 2 connected to each clamping component 1 in a one-to-one correspondence; each driving component 2 can drive each clamping component 1 to move closer to or further away from each other; the clamping component 1 includes a first clamping member 11 and a second clamping member 12 connected to each other, the first clamping member 11 and the second clamping member 12 are arranged at an angle and are used together to abut against and hold the outer wall of the conduit.
[0025] In the technical solution of this utility model, each of the driving components 2 drives the clamping components 1 to move and clamp the conduit. It is applicable to conduits of different diameters. The angle formed by the first clamping member 11 and the second clamping member 12 can effectively wedge part of the outer wall of the conduit into the angle. By clamping and fixing the conduit with at least two clamping components 1, conduits of different diameters can be stably clamped, which greatly improves construction efficiency and the stability of project quality.
[0026] To further improve the stability of the clamping device 200 for the catheter, in one embodiment, the first clamping member 11 and the second clamping member 12 are movably connected. The driving assembly 2 includes a first driving member 21 and a second driving member 22. The first driving member 21 is connected to the first clamping member 11 and can drive the first clamping member 11 to move. The second driving member 22 is connected to the second clamping member 12 and can drive the second clamping member 12 to move relative to the first clamping member 11 to change the angle. When the diameter of the catheter changes, the second driving member 22 can drive the second clamping member 12 to move, thereby changing the angle between the first clamping member 11 and the second clamping member 12, so as to include a larger range of curvature of the outer wall of the catheter within the angle. This not only makes it more adaptable to different diameters, but also improves the stability when all the clamping assemblies 1 clamp the catheter together.
[0027] like Figure 1 As shown, in one embodiment, the clamping assembly 1 includes one first clamping member 11 and two second clamping members 12. The two second clamping members 12 can further increase the clamping range, making the clamping more stable. In specific implementation, the first driving member 21 firstly drives each of the first clamping members 11 to jointly press against the conduit, and then the second driving member 22 drives the second clamping members 12 to move and press against the conduit, thereby jointly improving the stability of clamping the conduit. In this embodiment, the number of clamping assemblies 1 is two, but the specific number is not limited, but should be at least two. In specific settings, it is best if the two clamping assemblies 1 are arranged opposite each other. If the number is greater than two, it is best to arrange them evenly along the circumferential direction.
[0028] In one embodiment, such as Figure 1 As shown, to specifically achieve the clamping of the catheter by the first clamping member 11 and the second clamping member 12, the first clamping member 11 and the second clamping member 12 are plate-shaped structures, and their adjacent sides are rotatably connected, making it easier and faster to adjust the included angle between the first clamping member 11 and the second clamping member 12. In other embodiments, the specific shape of the first clamping member 11 and the second clamping member 12 is not limited, and they can also be block-shaped, arc-shaped, etc.
[0029] To further improve the clamping stability of the clamping assembly 1, in one embodiment, the first clamping member 11 and / or the second clamping member 12 have a friction portion 111. The friction portion 111 is used to abut against the outer wall of the catheter to increase the force between the clamping member and the catheter. Specifically, the first clamping member 11 has the friction portion 111, the second clamping member 12 has the friction portion 111, and both the first clamping member 11 and the second clamping member 12 have the friction portion 111. Figure 1 As shown, in this embodiment, both the first clamping part and the second clamping part have the friction part 111, and the friction part 111 consists of multiple protrusions. Since the outer periphery of the catheter is arc-shaped, it is difficult to completely fit the outer periphery wall of the catheter. The gap between each protrusion is used to further accommodate a small part of the outer wall of the catheter. The joint action of each protrusion makes the clamping assembly 1 clamp more firmly.
[0030] To prevent damage or deformation of the catheter due to over-clamping of the clamping assembly 1, in one embodiment, such as Figure 2 As shown, the fixing device 200 further includes a sensing component 3, which includes a sensing element 31 disposed on the clamping component 1 and a trigger element 32 disposed on the driving component 2. The sensing element 31 is electrically connected to the driving component 2. The trigger element 32 triggers the sensing element 31 when the clamping component 1 presses against the conduit. When the sensing element 31 is triggered, the driving component 2 is stopped by an electrical signal to properly clamp the conduit and avoid over-clamping.
[0031] To specifically implement the function of the sensing component 3, such as Figure 2 As shown, in one embodiment, the pressure sensor 31a and the contact 32a are located at opposite ends of the damping spring 33. The pressure sensor 31a is located inside the damping spring 33, and the contact 32a extends partially into the damping spring 33. When the first driving member 21 drives the first clamping member 11 to move, it compresses the damping spring 33. After the damping spring 33 is compressed to a certain extent, the contact 32a contacts the pressure sensor 31a. At this time, the pressure sensor 31a is compressed and sends an electrical signal to the first driving member 21 through the electrical control center, controlling the first driving member 21 to stop its driving action. The specific implementation of the sensing component 3 is not limited. In other embodiments, the sensing component 3 can also be a photoelectric sensing system, that is, the sensing element 31 is a photodetector, and the structure and shape of the trigger 32 are not limited. When the trigger 32 moves to the area of the photodetector, it is recognized and sensed by the photodetector, and the circuit is controlled to open or close by changing the light, thereby controlling the driving component 2.
[0032] The aforementioned sensing component 3 can be used between the first clamping member 11 and the first driving member 21, as well as between the second clamping member 12 and the second driving member 22.
[0033] To further improve the clamping stability of the catheter, such as Figure 3 and Figure 4As shown, in one embodiment, the fixing device 200 further includes an elastic limiting component 4, which includes a limiting ring 41 and an elastic abutment member. The limiting ring 41 and the clamping component 1 are spaced apart in the extension direction of the conduit. The elastic abutment member is disposed on the inner wall of the limiting ring 41, and the elastic extension and contraction direction of the elastic abutment member 42 is the radial direction of the limiting ring 41 and is used to abut against the outer wall of the conduit to clamp the conduit at different pipe segment positions. By clamping different pipe segments of the conduit, the stability of the conduit when conveying materials is improved. The inner diameter of the limiting ring 41 is the maximum diameter of the conduit that can be accommodated. When the diameter of the conduit changes, the degree of contraction of the conduit abutting and squeezing the elastic abutment member 42 is different, thereby realizing the clamping of conduits of different diameters.
[0034] To facilitate the passage of the catheter through the elastic limiting component 4 and reduce the possibility of the catheter being blocked by the elastic abutment, in one embodiment, such as Figure 4 As shown, the elastic limiting component 4 further includes a roller 43, which is located at the end of the elastic abutment member away from the inner wall of the limiting ring 41. Specifically, the roller 43 is positioned at the end that contacts the elastic abutment member when the conduit enters the limiting ring 41, allowing the conduit to enter and pass through the elastic limiting component 4 more smoothly. The rolling direction of the roller 43 is the same as the movement direction of the conduit.
[0035] This utility model also proposes a 2000-type cast-in-place pile, such as... Figure 3 As shown, the cast-in-place pile 2000 includes a support base 100 and a fixing device 200. The specific structure of the fixing device 200 is as described in the above embodiments. Since the cast-in-place pile 2000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The cast-in-place pile 2000 is used in concrete pouring construction. The cast-in-place pile 2000 includes a support base 100 and a fixing device 200. The support base 100 includes a support leg 101 and a mounting plate 102. The support leg 101 connects to and supports the mounting plate 102. The mounting plate 102 has a pouring port 103 extending through its thickness for the passage of the guide pipe. The fixing device 200 is connected to and located on one side of the mounting plate 102. The clamping component 1 of the fixing device 200 is located around the pouring port 103. The pouring port 103 is used for the passage of the guide pipe. The area below the pouring port 103 is the pouring construction area. After the guide pipe passes through the pouring port 103 and reaches the predetermined construction position, the fixing device 200 clamps and fixes the guide pipe, ensuring the stability of the guide pipe during the pouring construction process and guaranteeing construction quality.
[0036] The support leg 101 is telescopic to adapt to different construction environments and different grouting height requirements, and its specific telescopic method is not limited.
[0037] This utility model also proposes an infusion system 10000, such as Figure 3 As shown, the grouting system 10000 includes the cast-in-place pile 2000 and the spliced conduit 1000. The specific structure of the cast-in-place pile 2000 is as described in the above embodiments. Since the grouting system 10000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here. The grouting system 10000 is used for concrete grouting construction. The grouting system 10000 includes the cast-in-place pile 2000 and the spliced conduit 1000. The spliced conduit 1000 is inserted into the grouting port 103 and is used to transport concrete. The spliced conduit 1000 includes multiple conduit units 1000a. Each conduit unit 1000a is connected to the others by threads. The threaded connection makes the connection between each conduit unit 1000a tight, preventing material leakage. The use of a spliced conduit allows the conduit to adapt to various working conditions, adjust the conduit length, and make the transportation process more convenient.
[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
