[0022] Please refer to Figures 1 to 3 As shown, the present invention discloses a composite pipe pressure monitoring device for installing and locking a composite pipe 200. The composite pipe pressure monitoring device comprises a device frame 1, a moving component 2 installed on the device frame 1, a buffer component 3 for buffering the moving component 2, a fixed component 4 matched with the moving component 2, and a monitoring component 5 for monitoring the stretching and expansion changes of the composite pipe 200.

[0023] In the illustrated embodiment of the present invention, the device frame 1 includes a first bracket 11 and a second bracket 12. The device frame 1 is formed by welding a plurality of metal profiles. Of course, in other embodiments, the device frame 1 can also be formed in other ways.

[0024] The moving assembly 2 includes two first connecting plates 21 spaced apart, two groups of first fixed connecting shafts 22 mounted on the first connecting plates 21, a first limit spring 23 sleeved on the first fixed connecting shafts 22, a first connecting pipe joint 24 mounted on the first connecting plate 21 and located between the two groups of the first fixed connecting shafts 22, and a first joint locker 25 matched with the first connecting pipe joint 24. In the illustrated embodiment of the present invention, the moving assembly 2 includes at least one roller 26 mounted on the equipment frame 1, so that the moving assembly 2 can move freely with the expansion and contraction of the composite pipe 200 during pressing.

[0025] In the illustrated embodiment of the present invention, each of the first fixed connecting shaft rods 22 is fixed to the two first connecting plates 21 by two nuts 221 at both ends thereof, respectively, to facilitate assembly and disassembly. The first connecting pipe joint 24 can be quickly installed on the first connecting plate 21 at the front end by a screw nut 241, and the operation is simple, convenient and fast. In addition, one end of the first connecting pipe joint 24 is provided with a first threaded connection hole 242 connected to the pressing device and the exhaust device.

[0026] The first joint locker 25 slides forward and backward along the first fixed connection shaft 22. The first joint locker 25 includes a first locking pinch block 251 sleeved on the composite pipe 200.

[0027] The buffer assembly 3 includes a first buffer assembly 31 and a second buffer assembly 32 located on both sides of the moving assembly 2. The first buffer assembly 31 includes a first buffer rod 311 matched with the moving assembly 2, and the second buffer assembly 32 includes a second buffer rod 321 matched with the moving assembly 2. In the illustrated embodiment of the present invention, the first buffer rod 311 is a buffer cylinder piston push rod pushed out by hydraulic oil; accordingly, the buffer assembly 3 also includes a buffer cylinder 312 installed on the equipment frame 1 and a hydraulic pump station 313 connected to the buffer cylinder 312.

[0028] The moving assembly 2 can move freely with the expansion and contraction of the composite pipe 200 during the pressing. One end of the first fixed connecting shaft rod 22 is used to cooperate with the first buffer rod 311 , and the other end of the first fixed connecting shaft rod 22 is used to cooperate with the second buffer rod 321 .

[0029] The fixed assembly 4 is similar in structure to the movable assembly 2, and the main difference between the two is that the fixed assembly 4 is immovable. Specifically, in the illustrated embodiment of the present invention, the fixed assembly 4 includes two second connecting plates 41 spaced apart, two groups of second fixed connecting shafts 42 mounted on the second connecting plates 41, a second limit spring 43 sleeved on the second fixed connecting shafts 42, a second connecting pipe joint 44 mounted on the second connecting plate 41 and located between the two groups of second fixed connecting shafts 42, and a second joint locker 45 matched with the second connecting pipe joint 44.

[0030] In the illustrated embodiment of the present invention, each of the second fixed connection shaft rods 42 is fixed to the two second connection plates 41 by two nuts 421 at both ends thereof, respectively, to facilitate assembly and disassembly. The second connection pipe joint 44 can be quickly installed on the second connection plate 41 at the rear end by a screw nut 441, and the operation is simple, convenient and fast. In addition, one end of the second connection pipe joint 44 is provided with a second threaded connection hole 442 connected to the pressure device and the exhaust device.

[0031] The second joint locker 45 slides forward and backward along the second fixed connection shaft 42. The second joint locker 45 includes a second locking pinch block 451 sleeved on the composite pipe 200.

[0032] During installation, the composite pipe 200 is passed through the first joint locker 25 and the second joint locker 45; then, the first end 201 of the composite pipe 200 is sleeved on the first connecting pipe joint 24, and the first end 202 of the composite pipe 200 is sleeved on the second connecting pipe joint 44; the first joint locker 25 and the second joint locker 45 can move freely so as to observe whether the installation process of the composite pipe 200 is in place. After the composite pipe 200 is installed, the first limit spring 23 and the second limit spring 43 can limit the corresponding joint locker to move to the required buckling position to ensure the accuracy of the buckling position. Then, the first locking pinch block 251 and the second locking pinch block 451 are moved back and forth to respectively lock the first end 201 of the composite pipe 200 on the first connecting pipe joint 24 and the second end 202 of the composite pipe 200 on the second connecting pipe joint 44. Since the first joint locker 25 and the second joint locker 45 will be displaced during buckling, the first limit spring 23 and the second limit spring 43 can automatically adjust the required distance for displacement.

[0033] In the illustrated embodiment of the present invention, the first connecting pipe joint 24 and the first locking pinch block 251 as well as the second connecting pipe joint 44 and the second locking pinch block 451 are all detachably mounted on corresponding components. Therefore, when it is necessary to match the composite pipe 200 with different pipe diameters, it is only necessary to replace the appropriate connecting pipe joint and the locking pinch block, and two people can achieve rapid installation and pressing.

[0034] The moving assembly 2 can move freely with the expansion and contraction of the composite pipe 200 during the compression, so as to monitor the expansion and contraction changes of the composite pipe 200. In some cases, when the first end 201 of the composite pipe 200 instantly falls off the first connecting pipe joint 24, the impact force generated will move the moving assembly 2 forward quickly; at this time, the moving assembly 2 will contact the first buffer rod 311, and the piston rod will gradually reduce the impact force of the moving assembly 2 to stop, thus avoiding damaging the moving assembly 2. In addition, by providing the second buffer rod 321, it can be prevented that the composite pipe 200 pulls the moving assembly 2 back and damages it after the pipe bursts due to compression.

[0035] The monitoring component 5 includes a tension sensor 51 installed on the equipment frame 1 and connected to the second connecting pipe joint 44, and the tension sensor 51 is used to monitor the tension generated by the composite pipe 200 when the composite pipe 200 is pressed. In addition, the monitoring component 5 includes a rangefinder 52, and the rangefinder 52 is used to monitor the changes in the stretching and expansion of the composite pipe 200 when the composite pipe 200 is pressed. The rangefinder 52 can respectively measure the moving distance of the moving component 2 and the change in the pipe diameter of the composite pipe 200 under different pressures, and determine the changes in the composite pipe 200 under different pressures. The composite pipe pressure monitoring device of the present invention can be applied to real-time pressure monitoring of pipelines of various specifications. At this time, there are several composite pipes 200, and the composite pipe pressure monitoring device can perform real-time pressure monitoring on these composite pipes 200; the composite pipe pressure monitoring device also includes a multi-channel data acquisition device (not shown), which can simultaneously monitor multiple data signals and perform multi-angle recording and storage.

[0036] Compared with the prior art, the present invention facilitates connection with the composite pipe 200 by providing the first and second connecting pipe joints 24, 44 and the first and second joint lockers 25, 45 on the mobile component 2; in addition, by providing the monitoring component 5, it is possible to monitor the stretching and expansion changes of the composite pipe 200, thereby expanding its functions and improving the intelligence of the equipment. The composite pipe pressure monitoring equipment of the present invention is simple to operate, convenient and quick to install, and has low work intensity for workers. It is a huge technological innovation in the field of composite pipe pressure monitoring equipment. When in use, the composite pipe pressure monitoring equipment of the present invention can be used for blasting tests as well as long-term pressure stabilization tests.
