Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a lockable anti-slip hose guide cap device and a hose installation method. Background Technology

[0002] In practical applications, flexible permeable pipes have begun to be used on a large scale in slope drainage. Unlike the open-cut method of directly installing flexible permeable pipes, most slope drainage methods involve first drilling a hole with a diameter slightly larger than the diameter of the permeable pipe, exceeding the diameter by 50cm. The hole is then cleaned with an air compressor, and a long rod (steel bar, PVC pipe, threader, etc.) is used to push the permeable pipe into the hole. However, the flexible permeable pipe has a helical spring as its internal framework, and the friction between the hole walls is relatively high. After installation, the spring has a significant rebound force, causing the flexible pipe to retract. However, this retraction is often overlooked during construction, resulting in a shorter actual installation length and poorer quality. Summary of the Invention

[0003] To address the problems existing in the prior art, a lockable anti-slip hose guide cap device and a hose installation method are provided. During installation, the guide cap is fixed to the top of the hose, which makes hose installation simpler and more efficient, prevents retraction, and improves installation quality.

[0004] To address the aforementioned technical problems, a first aspect of this application provides a lockable anti-slip flexible hose cap device, comprising:

[0005] The guide cap has a cylindrical space inside for inserting a flexible tube, and the outer wall of the guide cap has multiple grooves that penetrate the outer wall along the length direction;

[0006] A positioning bracket is fixed to one end of the guide cap. The center of the positioning bracket is provided with a first rotating shaft that rotates around its own axis. The lower end of the first rotating shaft is connected to a non-circular connector.

[0007] A turntable, the center of which has a non-circular hole that matches and fits with the non-circular connector, and multiple curved triangular gears are spaced along the outer edge of the turntable, the curved triangular gears having multiple oblique serrations on the inclined surface away from the turntable;

[0008] The L-shaped anchor plate has its long side rotatably mounted in the groove in the radial direction of the guide cap, and its short side moves on the oblique saw teeth when the turntable rotates.

[0009] The mounting rod has a sleeve at one end that matches and fits with the non-circular connector.

[0010] Furthermore, the outer wall of the guide cap is provided with multiple through holes for the tie wire of the binding hose to pass through.

[0011] Furthermore, a conical top of the guide cap is fixedly connected to one end of the guide cap near the positioning bracket.

[0012] Furthermore, the anchor plate has a second pivot at one end of its long side that is relatively close to the short side. The two ends of the second pivot extend beyond the width of the long side. The inner sides of the groove on the outer wall of the guide cap have pivot holes for the two ends of the second pivot to be inserted.

[0013] Furthermore, the non-circular connector is a hexagonal prism nut.

[0014] Furthermore, the mounting rod is a telescopic rod.

[0015] A first aspect of this application provides a hose installation method using any of the lockable anti-slip hose guide cap devices described above, comprising the following steps:

[0016] Keep the long side of the anchor plate in the groove on the outer wall of the guide cap, and fix one end of the hose in the cylindrical space of the guide cap;

[0017] Insert the mounting rod into the hose until the sleeve on one end of the mounting rod is connected to the non-circular connector at the lower end of the first rotating shaft. Use the mounting rod to push the guide cap with the hose fixed in place into the drill hole at the construction site.

[0018] Rotate the mounting rod in the specified direction to make the turntable rotate. The oblique saw teeth of the triangular gear on the outer edge of the turntable gradually push the short side of the anchor plate away, so that the long side of the anchor plate rotates out of the groove and embeds into the hole wall of the drilled hole.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention adds an expandable anchoring plate to the guide cap and locks the anchoring plate with oblique serrations, allowing it to rotate in one direction, thereby increasing anchoring strength and stability, improving project quality, and facilitating quick and easy installation.

Detailed Implementation

[0031] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] See Figures 1-7 This invention provides a lockable anti-slip hose guide cap device, which mainly includes a guide cap and an installation rod. During installation, the guide cap is fixed to the top of the hose, which makes hose installation simpler and more efficient, prevents retraction, and improves installation quality.

[0034] Specifically, a lockable anti-slip hose guide cap device according to an embodiment of the present invention mainly includes a guide cap and an installation rod 202, and further includes components such as a positioning bracket 302, a turntable 504, and multiple anchoring plates 401 installed inside the guide cap.

[0035] The guide cap mainly comprises two parts: a guide cap top 101 and a guide cap outer wall 102. The guide cap top 101 is a hollow cone shape, facilitating insertion into the ground borehole during installation. The guide cap outer wall 102 is a circular tube with an internal cylindrical space for inserting a flexible hose. During installation, it allows the flexible hose to be fixed to the circular tube, serving as a connection between the hose and the tube. Furthermore, when the installation rod 202 pushes the guide cap into the ground borehole, it pulls the flexible hose. Preferably, the guide cap outer wall 102 has multiple through holes 103 for the tying wire of the flexible hose to pass through, facilitating the fixing of the flexible hose to the circular tube. Simultaneously, when pushed into the ground borehole, it allows air to be expelled, balancing the internal and external air pressure and further facilitating hose installation. Preferably, the guide cap outer wall 102 has multiple grooves 104 along its length. In this embodiment, there are three hollow grooves 104 that penetrate the guide cap outer wall 102.

[0036] The positioning bracket 302 is fixed to one end of the outer wall 102 of the guide cap, relatively close to the top 101 of the guide cap. The positioning bracket 302 has a central circular hole, within which a first rotating shaft 501, rotatable about its own axis, is rotatably mounted. A non-circular connector 503 is connected to the lower end of the first rotating shaft 501. Preferably, the upper end of the first rotating shaft 501 extends upwards above the positioning bracket 302 and is fixedly fitted with a retaining ring 502. The outer diameter of the retaining ring 502 is larger than the diameter of the central circular hole in the positioning bracket 302, preventing the first rotating shaft from falling downwards off the positioning bracket 302. In this embodiment, the non-circular connector 503 is a hexagonal prism nut, but any shape other than circular can be used to limit its relative rotation with the turntable 504. The hexagonal prism nut is located below the positioning bracket 302 and coaxially connected to the lower end of the first rotating shaft 501. During use, an internal hexagonal wrench sleeve 201 is provided on the upper part of the mounting rod 202 and can be fitted into it.

[0037] The turntable 504 is a disc, smaller in size than the outer wall of the guide cap, and located inside the outer wall of the guide cap. A non-circular hole is formed at the center of the turntable 504 to fit into the non-circular connector 503. In this embodiment, the non-circular connector 503 is a hexagonal prism nut. Therefore, the non-circular hole at the center of the turntable 504 is a hexagonal hole of the same shape. The hexagonal prism nut can pass through the hexagonal hole but cannot rotate within it. Thus, the turntable 504 and the hexagonal prism nut are connected together without relative movement. Multiple curved triangular gears 505 are spaced apart along the outer edge of the turntable 504. In this embodiment, there are three curved triangular gears 505. The curvature of the curved surface is consistent with the outer extension of the turntable 504 and they are fixed on the turntable 504 on the side away from the top of the guide cap. The curved triangular gears 505 are as follows: Figure 4 and Figure 5As shown, the curved triangular gear 505 has multiple continuous oblique saw teeth 506 on the inclined surface away from the turntable. The oblique saw teeth 506 on the inclined surface of the three curved triangular gears 505 are inclined in the same direction. The oblique saw teeth 506 can lock the anchor plate 401, so that the turntable 504 can only rotate in one direction.

[0038] The L-shaped anchor plate 401 has a long side and a short side, with one end of the long side perpendicularly connected to the other end of the short side, forming an angle at the connection. Specifically, the number of anchor plates 401 is the same as the number of grooves 104 on the outer wall 102 of the guide cap and the number of curved triangular gears 505 on the turntable 504, which are three in this embodiment. The long side of the anchor plate 401 is rotatably mounted in the groove 104 of the outer wall 102 of the guide cap in the radial direction, and the short side of the anchor plate 401 moves on the oblique saw teeth 506 when the turntable 504 rotates. Preferably, the width of the short side of the anchor plate 401 is equal to the width of each oblique saw tooth 506. Furthermore, in this embodiment, each anchoring piece 401 has a second pivot at one end (i.e., the bend) of its long side, which is relatively close to its short side. The two ends of the second pivot extend vertically outwards from both sides of the width direction of the long side. The inner sides of the groove 104 of the guide cap outer wall 102 are provided with pivot holes for the two ends of the second pivot to be inserted and rotated. Thus, the bend of the anchoring piece 401 is rotatably connected to the groove 104 of the guide cap outer wall 102 through the second pivot. Before the hose is installed, the anchoring piece 401 can be retracted into the groove 104 of the outer wall. After the hose is installed in place, the anchoring piece 401 can be rotated outwards and opened to embed into the hole wall of the ground drill. Therefore, the second pivot and the anchoring piece 401 form a lever shape. The rotation of the curved triangular gear 505 can move one end of the anchoring piece 401, causing the other end to open further and lock the hole wall, thus playing a role in anti-slip locking.

[0039] The mounting rod 202 consists of a long rod and an internal hexagonal wrench sleeve 201 at the top. The shape of the internal hexagonal wrench sleeve 201 is consistent with that of the non-circular connector 503. By fitting the internal hexagonal wrench sleeve 201 onto the non-circular connector 503, the turntable 504 can be controlled to rotate relative to the positioning bracket 302. The positioning bracket 302 consists of a disc with a central size smaller than that of the turntable 504 and three legs evenly distributed around it. The positions of the three legs correspond to the positions of the three grooves 104 on the outer wall 102 of the guide cap and are fixedly embedded in the top of the corresponding grooves 104, so that the positioning bracket 302 is fixed together with the outer wall 102 of the guide cap and cannot rotate relative to it. Furthermore, the hexagonal socket 201 is relatively long, which can prevent the guide cap from falling off during the top delivery (it can be designed to be magnetic if necessary). After the guide cap is in place, the internal hexagonal nut can be tightened. The hexagonal nut is screwed into the thread at the lower end of the first rotating shaft 501 (the first rotating shaft can be a threaded shaft, and the retaining ring 502 can also be fixed to the upper end of the first rotating shaft by setting an internal thread). The lower long rod part of the mounting rod 202 can be a telescopic rod, which can be used to adjust the length according to the required installation length of the hose. The telescopic rod can adopt any existing structure that can achieve telescopic movement, such as two sleeves connected by threads. Among them, the first rotating shaft 501, retaining ring 502, hexagonal nut, turntable 504 and curved triangular gear 505 can be regarded as a whole, which is fixed inside the guide cap by the positioning bracket 302, and this whole can be rotated by the mounting rod 202.

[0040] This invention also provides a hose installation method using the lockable anti-slip hose guide cap device as described in the above embodiments. The installation method is as follows:

[0041] Before installation, cut the hose to the required length, paying attention to the internal structure of the guide cap to ensure that the anchor plate 401 is within the groove 104 on the outer wall of the guide cap and that the anchor plate 401 is not open. Insert one end of the hose into the guide cap, securing it through the through hole 103 on the outer wall of the guide cap with tie wire to prevent it from falling off during installation. Then, insert the hexagonal wrench socket 201 into the hexagonal nut inside the guide cap, and rotate it slightly while pushing it forward, in the opposite direction to the opening direction of the anchor plate 401. After pushing the hose to the designated position in the borehole, rotate the installation rod 202 again to open the anchor plate 401 and embed it into the borehole wall, providing anti-slip anchoring. As time increases, the friction between the hose outer wall and the borehole wall decreases, and some mud and sand fill the gap between the hose and the borehole, at which point the hose is perfectly installed.

[0042] This invention adds an expandable anchoring plate to the guide cap and locks the anchoring plate with oblique serrations, allowing it to rotate in one direction, thereby increasing anchoring strength and stability, improving project quality, and facilitating quick and easy installation.

[0043] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and scope of this application are included within the scope of protection of this application.
