Description

Technical Field

[0001] The utility model relates to the technical field of cable protection tube production, in particular to a pressure simulation device for cable protection tubes. Background Art

[0002] Cable protection conduits are mechanically strong tubes designed to protect cables from damage. They are primarily installed where communication cables and power lines intersect. They prevent power line breaks and short circuits, which could lead to live cables and wire ropes. They protect cables, switches, and circuit boards, ultimately preventing damage to the entire device. They also provide some isolation from magnetic interference from the power lines.

[0003] Cable protection tubes are generally buried underground after the cables are laid. In order to provide effective protection, cable protection tubes should be able to withstand a certain amount of pressure. Existing testing methods mainly measure the pressure resistance of the pipes by applying pressure to the pipes. However, in actual use, the surrounding areas of the buried pipes will be filled with soil and gravel for support. Therefore, the pressure conditions must be effectively simulated, and the simulation equipment needs to facilitate the filling and rapid discharge of the fillers to facilitate the simulation testing work.

The limit guide seat is fixedly arranged on the back of the frame, the oil cylinder is fixedly arranged on both sides of the frame, the support roller is installed at the bottom of the oil cylinder, the roller seat is fixedly arranged at the bottom of the frame, the vibration roller is movably connected to the inner side of the roller seat, the second cylinder is installed inside the roller seat, the sealing plate is fixedly arranged at the telescopic end of the second cylinder, and the guide strip is fixedly arranged at the bottom of the frame.

[0007] In a preferred embodiment of the present invention, a discharge port is provided at the bottom of the frame, and the sealing plate is fitted to the bottom of the frame and covers the bottom of the discharge port of the frame;

[0009] In a preferred embodiment of the present invention, a guide groove is provided on the inner side of the guide strip, and both sides of the sealing plate are clamped in the guide groove on the inner side of the guide strip;

[0010] The guide strips not only play an effective guiding role for the sealing plate, but also effectively support both sides of the sealing plate, thereby ensuring the strength of the sealing plate and preventing the filling from leaking.

[0013] In a preferred embodiment of the present invention, the pull plate is arranged inside the limiting guide seat;

[0014] When the pull plate at the end of the first cylinder pushes and pulls the limit guide seat, the forward and backward movement of the box body can be effectively controlled. At this time, the vibration roller clamped on the top of the shaking bar will cause the entire box body to vibrate, thereby facilitating the compaction of the filler and the filling work of the filler. When unloading, opening the sealing plate can facilitate the rapid discharge of the filler. The pull plate clamped in the limit guide seat plays an adaptive adjustment effect when the frame moves up and down.

[0015] The beneficial effects of the utility model are:

[0016] This cable protection tube pressure simulation device changes the traditional method of testing the compressive strength of cable protection tubes. It simulates the state of the tube being buried underground by placing fillers inside the frame and applies pressure to it to test its compressive strength and protective effect. The placed fillers can be compacted quickly and effectively, and after the test is completed, they can be quickly unloaded to facilitate the testing work. BRIEF DESCRIPTION OF THE DRAWINGS

The support frame 2 is fixedly arranged at one end of the top of the workbench 1, the hydraulic press 3 is fixedly arranged at the top of the support frame 2, the pressure seat 4 is fixedly arranged at the telescopic end of the hydraulic press 3, the pressure roller 5 is clamped on the inner side of the bottom of the pressure seat 4, the first cylinder 6 is fixedly arranged on the back of the support frame 2, the pull plate 7 is fixedly arranged at the telescopic end of the first cylinder 6, the shaking bar 8 is fixedly arranged on the upper surface of the workbench 1, and the protection tube installation mechanism 9 is arranged on the upper surface of the workbench 1 The protective tube installation mechanism 9 includes a frame 91, a limiting guide seat 92, an oil cylinder 93, a support roller 94, a roller seat 95, a vibration roller 96, a second cylinder 97, a sealing plate 98 and a guide bar 99. The limiting guide seat 92 is fixedly arranged on the back of the frame 91, the oil cylinder 93 is fixedly arranged on both sides of the frame 91, the support roller 94 is installed at the bottom of the oil cylinder 93, the roller seat 95 is fixedly arranged at the bottom of the frame 91, the vibration roller 96 is movably connected to the inner side of the roller seat 95, the second cylinder 97 is installed inside the roller seat 95, the sealing plate 98 is fixedly arranged at the telescopic end of the second cylinder 97, and the guide bar 99 is fixedly arranged at the bottom of the frame 91.

[0024] Specifically, a discharge port is provided at the bottom of the frame 91, and the sealing plate 98 is fitted with the bottom of the frame 91 and covers the bottom of the discharge port of the frame 91. A guide groove is provided on the inner side of the guide bar 99, and both sides of the sealing plate 98 are clamped in the guide groove inside the guide bar 99. A connecting plate is provided at the bottom of the sealing plate 98. The telescopic end of the second cylinder 97 passes through and extends to the inside of one side of the roller seat 95, and is fixed to the connecting plate at the bottom of the sealing plate 98. The vibration roller 96 is clamped on the top of the shaking bar 8, and a discharge port is provided on the upper surface of the workbench 1 at a position corresponding to the discharge port at the bottom of the frame 91. The pull plate 7 is clamped inside the limiting guide seat 92.

[0025] In this embodiment, a circular hole is opened on the side of the frame 91 to facilitate the insertion of the cable protection tube. After the cable protection tube is inserted into the circular hole on the side of the frame 91, fillers such as soil and sand are placed in the frame 91. Then the first cylinder 6 is controlled to perform reciprocating motion, and the pull plate 7 at the front end of the first cylinder 6 is clamped into the limit guide seat 92, pushing and pulling the frame 91 back and forth. At this time, the vibration roller 96 runs on the surface of the shaking bar 8, causing the frame 91 to shake up and down, so that the filler is filled into the gap. At this time, the hydraulic press 3 extends, driving the pressure seat 4 to descend, and the pressure roller 5 is slightly lowered to slightly press the filler to ensure that the filler is compacted.

[0026] Furthermore, the first air cylinder 6 is extended to a fixed position, and the oil cylinder 93 is controlled to rise. The oil cylinder 93 rises to separate the vibration roller 96 from the shaking bar 8, and then the hydraulic press 3 is controlled to continue to extend to ensure that the pressure roller 5 applies pressure to the top of the filler. At this time, the first cylinder 6 is controlled to be extended and retracted to control the frame 91 to move back and forth under the action of the supporting roller 94. As the hydraulic press 3 continues to extend, the pressure of the pressure roller 5 on the filler and the internal embedded cable protection tube continues to increase. The status of the cable protection tube can be observed by observing from the side or placing an observation camera inside the cable protection tube. , until it is deformed and damaged under pressure, so as to understand the pressure that the cable protection tube can withstand after being buried underground. After the detection is completed, the hydraulic press 3 contracts, the oil cylinder 93 contracts, and the vibration roller 96 contacts the shaking bar 8 again. At this time, the second cylinder 97 contracts, and the bottom sealing plate 98 is opened under the guidance of the guide bar 99, and the filler can be discharged from the discharge port at the bottom of the frame 91. At this time, the first cylinder 6 performs a reciprocating motion to drive the frame 91 to shake, thereby loosening the compacted filler and falling off, which is convenient for the rapid discharge of the filler and is collected from the discharge port on the surface of the workbench 1 for reuse.
