Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber reinforced plastic pipes, in particular to a new type of glass fiber reinforced plastic pipe. Background Art

[0002] Fiberglass pipes are widely used and effective in protecting cables. They are a new type of composite pipe, primarily composed of resin and glass fiber. This material offers numerous advantages, including high strength, lightweight, corrosion resistance, excellent electrical insulation, flame retardancy, and excellent heat and frost resistance.

[0003] FRP pipes are used in urban power grid construction and renovation projects, municipal renovation projects, civil aviation airport construction, industrial park and residential area construction, and transportation road and bridge construction. The superior performance of FRP pipes is particularly evident in special environments such as where cables cross bridges and rivers.

[0004] However, the patents under the existing technology have the following disadvantages:

[0005] (1) The existing utility model FRP pipes do not have components inside them that can clamp cables, provide stable support for cables, and reduce the pulling force and vibration of cables. Cables are generally placed in the FRP pipe in an air-suspended manner to avoid accumulation and facilitate heat dissipation. However, when the FRP pipe is too long, the weight of the cable is large, and the pulling force on both ends increases. If there is no clamping support in the middle of the cable, the two ends of the cable are easily pulled and damaged. When the FRP pipe is hit, the cable is also prone to vibration in the FRP pipe and is easily damaged. Utility Model Content

[0006] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a glass fiber reinforced plastic pipe which can clamp and support suspended cables in the pipe, reduce the tension on both ends of the cables, and slow down the vibration of the cables when the glass fiber reinforced plastic pipe is hit.

[0007] In order to solve the above problems, the technical solution of the present utility model is as follows: a new type of glass fiber reinforced plastic pipe, comprising: a glass fiber reinforced plastic pipe body, a pulling buffer assembly and a cable clamping assembly; the pulling buffer assembly is arranged inside the glass fiber reinforced plastic pipe body, and the cable clamping assembly is arranged inside the pulling buffer assembly;

[0009] Furthermore, the cable clamping assembly includes:

[0010] A connecting rod, one end of which is fixedly connected to a side of each sliding frame close to the center line of the glass fiber reinforced plastic tube body;

[0011] A fixed clamp ring, the fixed clamp ring being fixedly connected to the other end of each connecting rod;

[0012] A rotating clamping ring, wherein the rotating clamping ring is rotatably connected to both sides of the fixed clamping ring via a connecting shaft;

[0013] A rotating rod, the rotating rod being rotatably connected to both sides of each sliding frame via a connecting shaft;

[0014] A rotating tube, the rotating tube being rotatably connected to a side of each rotating clamping ring away from the ring center via a connecting shaft, and the rotating rod being slidably connected to the rotating tube;

[0015] Spring 2, one end of the spring 2 is fixedly connected to the end of the rotating tube away from the tube mouth, and the other end of the spring 2 is fixedly connected to one end of the rotating rod inserted into the rotating tube.

[0016] Furthermore, the spring 1 and the spring 2 are both provided with dampers, and the dampers can slow down the reciprocating rebound of the spring 1 and the spring 2.

In the following description, the same numbers in different drawings represent the same or similar elements unless otherwise represented. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0025] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0026] Embodiment 1:

[0027] As Figures 1 to 4 shown, a novel glass steel pipe, comprising: glass steel pipe body 1, pull buffering subassembly 2 and cable clamping subassembly 3, pull buffering subassembly 2 is set up inside glass steel pipe body 1, and cable clamping subassembly 3 is set up inside pull buffering subassembly 2.

[0028] The pull buffer assembly 2 includes: a fixed plate 1 201, a fixed plate 202, a limiting shaft 203, a sliding frame 204 and a spring 1 205; the fixed plate 1 201 has several fixedly connected to the inner wall of the glass fiber reinforced plastic tube body 1 at equal angles, the fixed plate 202 has several fixedly connected to the inner wall of the glass fiber reinforced plastic tube body 1 at equal angles corresponding to the fixed plate 1 201, the limiting shaft 203 has several fixedly connected between the fixed plate 1 201 and the fixed plate 2 202 at equal intervals, the sliding frame 204 has several limiting shafts 203 passing through it and is slidably connected to the multiple limiting shafts 203, and the spring 1 205 is sleeved on the outside of each limiting shaft 203 and is fixedly connected between the sliding frame 204 and the fixed plate 1 201 and the sliding frame 204 and the fixed plate 2 202.

[0029] The cable clamping assembly 3 includes: a connecting rod 301, a fixed clamping ring 302, a rotating clamping ring 303, a rotating rod 304, a rotating tube 305 and a second spring 306. One end of the connecting rod 301 is fixedly connected to the side of each sliding frame 204 close to the center line of the glass fiber reinforced plastic pipe body 1, the fixed clamping ring 302 is fixedly connected to the other end of each connecting rod 301, the rotating clamping ring 303 is rotatably connected to both sides of the fixed clamping ring 302 through a connecting shaft, the rotating rod 304 is rotatably connected to both sides of each sliding frame 204 through a connecting shaft, the rotating tube 305 is rotatably connected to the side of each rotating clamping ring 303 away from the ring center through a connecting shaft, the rotating rod 304 is slidably connected to the rotating tube 305, one end of the second spring 306 is fixedly connected to the end of the rotating tube 305 away from the pipe opening, and the other end of the second spring 306 is fixedly connected to one end of the rotating rod 304 inserted into the rotating tube 305.

[0030] Both spring 1 205 and spring 2 306 have built-in dampers, which can slow down the reciprocating rebound of spring 1 205 and spring 2 306.

[0031] In actual use, the cable is pulled to align it with the openings of the two rotating clamping rings 303. The cable is pressed down with force, causing the rotating clamping ring 303 to rotate, thereby increasing the opening between the two rotating clamping rings 303 and inserting the cable into the fixed clamping ring 302. At this time, the second spring 306 extends, pushing the rotating rod 304 and the rotating tube 305, causing the rotating clamping ring 303 to rotate and reset, thereby reducing the opening between the two rotating clamping rings 303 and locking the cable to prevent it from being disengaged. The inner rings of the rotating clamping ring 303 and the fixed clamping ring 302 are fixedly connected with a non-slip rubber film to prevent the cable from rotating and sliding between the rotating clamping ring 303 and the fixed clamping ring 302, thus completing the installation and fixation of the cable. Afterwards, multiple new fiberglass reinforced plastic pipes are assembled to complete the protection of the cable.

[0032] When the cable is pulled violently, the cable will drive the sliding frame 204 to slide on the outside of the limit shaft 203, squeezing the spring 1 205. The spring 1 205 can buffer the pulling force. The damper of the spring 1 205 can slow down the reciprocating rebound of the spring 1 205, so that the pulled cable can quickly restore stability and reduce subsequent vibration.

[0033] When the FRP tube body 1 is subjected to a violent vertical impact, the cable will vibrate in the rotating clamp ring 303 and the fixed clamp ring 302. At this time, the rotating clamp ring 303 will rotate slightly, causing the rotating rod 304 to slide into the rotating tube 305, squeezing the second spring 306. The second spring 306 can buffer the squeezing force of the vibration. The damper of the second spring 306 can slow down the reciprocating rebound of the second spring 306, so that the rotating clamp ring 303 can quickly and stably reset, slowing down the vibration of the cable and protecting the cable.

[0034] The supporting force of the second spring 306 is relatively strong, so when the cable vibrates, the cable will not slip out of the rotating clamp ring 303 and the fixing bracket 302.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
