Description

Technical Field

[0001] This utility model relates to the field of cable protection pipe technology, and in particular to a cable protection pipe testing device. Background Technology

[0002] For example, in a cable protection pipe testing device (application number: 202420953643.7) disclosed on the Chinese Patent website, when limiting the cable protection pipe to be tested, a drive motor is used to control four fixed arc plates to limit the cable protection pipe. This limiting method requires the four fixed arc plates to be exactly attached to the inside of the cable protection pipe at the same time. Once there is a deviation, the cable protection pipe will be unstable. In addition, when testing the stiffness of the cable protection pipe, the specific value cannot be detected, so the specific load-bearing capacity of the cable protection pipe cannot be tested. Utility Model Content

[0003] To address the technical problems of existing cable protection pipes being prone to unstable fixing and the inability to test their specific load-bearing capacity, this utility model proposes a cable protection pipe testing device.

[0004] This utility model proposes a cable protection pipe testing device, which includes a mounting base. A control device is provided on the outside of the mounting base. The control device includes a control motor, a threaded rod, a moving plate, a pressing plate, and an arc plate. The control motor controls the threaded rod to rotate, the threaded rod drives the moving plate to move, and the pressing plate drives the arc plate to move.

[0005] Preferably, a fixing plate is fixedly installed on the front surface of the mounting base, the control motor is installed inside the fixing plate, the threaded rod is fixedly connected to the rotating shaft of the control motor, and a limit groove is formed inside the mounting base.

[0006] The above technical solution controls the rotation of the threaded rod by the motor, and the limiting groove facilitates the movement of the limiting plate.

[0007] Preferably, a limiting plate is slidably inserted into the inside of the limiting groove, the movable plate is fixedly installed on the outer surface of the limiting plate, the inside of the movable plate is threadedly connected to the outer surface of the threaded rod, and a plug rod is slidably inserted into the inside of the movable plate.

[0008] Through the above technical solution, the limiting plate moves within the limiting groove, ensuring that the moving plate always remains horizontal during movement.

[0009] Preferably, the extrusion plate is fixedly installed on the front end surface of the insertion rod, a pressure sensor is fixedly installed on the left outer surface of the extrusion plate, and the arc plate is fixedly installed on the right outer surface of the extrusion plate.

[0010] With the above technical solution, when the threaded rod rotates, it drives the moving plate to move, and the moving plate squeezes the pressure sensor, causing the squeezing plate and the arc plate to move.

[0011] Preferably, a drive motor is fixedly installed inside the mounting base, and a bidirectional threaded screw is fixedly installed on the shaft of the drive motor.

[0012] With the above technical solution, when the drive motor starts, the rotating shaft drives the bidirectional threaded screw to rotate.

[0013] Preferably, a sliding retaining plate is slidably inserted into the interior of the mounting base. The two sliding retaining plates are horizontally symmetrically distributed with the axis of the mounting base as the center of symmetry. The interior of each of the two sliding retaining plates is threadedly connected to the outer surface of a bidirectional threaded screw. A sliding plate is fixedly installed on the upper surface of each of the two sliding retaining plates. A mounting rod is slidably connected to the upper surface of the mounting base. An alarm is fixedly installed on the outer surface of the mounting rod. A retaining plate is fixedly installed on the lower surface of the mounting rod. An adjusting rod is threadedly connected to the interior of the retaining plate. The outer surface of the adjusting rod is threadedly connected to the interior of the mounting base. A vertical plate is fixedly installed on the upper surface of the mounting base.

[0014] With the above technical solution, when the bidirectional threaded screw rotates, it will drive the two sliding plates to move horizontally towards each other, causing the two sliding plates to clamp the cable protection pipe. Rotating the adjusting rod will control the clamping plate to drive the installation rod to move, so that the alarm is attached to the inner wall of the cable protection pipe.

[0015] The beneficial effects of this utility model are as follows:

[0016] By setting up a control device, when limiting the cable protection pipe, the cable protection pipe is first placed on the mounting base against the surface of the vertical plate. Then, the drive motor is started, causing the bidirectional threaded screw to rotate, controlling the two sliding plates to move horizontally towards each other. This causes the two sliding plates to clamp the cable protection pipe. The adjusting rod is rotated, controlling the clamping plates to move the mounting rod, so that the alarm is against the inner wall of the cable protection pipe. When testing the rigidity of the cable protection pipe, when the control motor is started, driving the threaded screw to rotate and moving the moving plate forward, the front end of the moving plate directly contacts and presses against the pressure sensor fixed to the left side of the extrusion plate, thereby applying axial thrust to the pressure sensor. The insertion rod is slidably inserted into the moving plate, with its front end fixed to the extrusion plate, thus ensuring the synchronization and guidance of the movement of the extrusion plate and the moving plate, and assisting in driving or guiding the extrusion plate to reset when the moving plate retracts. The extrusion plate moves within the space of the mounting base, and its position is naturally constrained by the boundary of this space. This causes the extrusion plate and the arc plate to move, and the arc plate to extrude the cable protection pipe. At this time, the pressure sensor will measure the pressure reading. When the cable protection pipe deforms, the alarm will be compressed and thus trigger an alarm. By observing the reading of the pressure sensor, the stiffness of the cable protection pipe can be detected, achieving the effect of stably limiting the cable protection pipe and facilitating the detection of the specific load-bearing capacity of the cable protection pipe.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A cable protection pipe testing device includes a mounting base 1. To facilitate the testing of the rigidity of the cable protection pipe, a control device is provided on the outside of the mounting base 1. The control device includes a control motor 2, a threaded rod 3, a moving plate 4, a pressing plate 5, and an arc plate 6. The control motor 2 controls the threaded rod 3 to rotate, the threaded rod 3 drives the moving plate 4 to move, and the pressing plate 5 drives the arc plate 6 to move.

[0024] To facilitate the movement of the limit plate 13 by controlling the motor 2, a fixed plate 11 is fixedly installed on the front surface of the mounting base 1. The motor 2 is installed inside the fixed plate 11, and the threaded rod 3 is fixedly connected to the rotating shaft of the motor 2. A limit groove 12 is opened inside the mounting base 1. The motor 2 controls the threaded rod 3 to rotate, and the limit groove 12 facilitates the movement of the limit plate 13.

[0025] To ensure that the moving plate 4 always moves horizontally, a limiting plate 13 is slidably inserted into the limiting groove 12. The moving plate 4 is fixedly installed on the outer surface of the limiting plate 13. The inside of the moving plate 4 is threadedly connected to the outer surface of the threaded rod 3. A plug rod 41 is slidably inserted into the inside of the moving plate 4. The limiting plate 13 moves within the limiting groove 12, ensuring that the moving plate 4 always moves horizontally.

[0026] To facilitate the control of the movement of the extrusion plate 5 and the arc plate 6, the extrusion plate 5 is fixedly installed on the front end surface of the insertion rod 41. A pressure sensor 51 is fixedly installed on the left outer surface of the extrusion plate 5, and the arc plate 6 is fixedly installed on the right outer surface of the extrusion plate 5. When the threaded rod 3 rotates, it drives the moving plate 4 to move. The moving plate 4 squeezes the pressure sensor 51, causing the extrusion plate 5 and the arc plate 6 to move.

[0027] To facilitate the control of the rotation of the bidirectional threaded screw 15, a drive motor 14 is fixedly installed inside the mounting base 1. The bidirectional threaded screw 15 is fixedly installed on the shaft of the drive motor 14. When the drive motor 14 starts, the shaft drives the bidirectional threaded screw 15 to rotate.

[0028] To facilitate limiting the movement of the cable protection pipe to be inspected, a sliding clamping plate 16 is slidably inserted inside the mounting base 1. The two sliding clamping plates 16 are horizontally symmetrically distributed with the axis of the mounting base 1 as the center of symmetry. The interior of each sliding clamping plate 16 is threadedly connected to the outer surface of the bidirectional threaded screw 15. A sliding plate 17 is fixedly installed on the upper surface of each sliding clamping plate 16. An installation rod 18 is slidably connected to the upper surface of the mounting base 1. An alarm 19 is fixedly installed on the outer surface of the installation rod 18. A clamping plate 110 is fixedly installed on the lower surface of the installation rod 18. An adjusting rod 111 is threadedly connected inside the clamping plate 110. The outer surface of the adjusting rod 111 is threadedly connected to the interior of the mounting base 1. A vertical plate 112 is fixedly installed on the upper surface of the mounting base 1. When the bidirectional threaded screw 15 rotates, it will drive the two sliding clamping plates 16 to move horizontally towards each other, causing the two sliding plates 17 to clamp the cable protection pipe. Rotating the adjusting rod 111 controls the clamping plate 110 to drive the installation rod 18 to move, so that the alarm 19 is against the inner wall of the cable protection pipe.

[0029] By setting a control device, when limiting the cable protection pipe, the cable protection pipe is first placed on the mounting base 1, and then the drive motor 14 is started, causing the bidirectional threaded screw 15 to rotate, controlling the two sliding clamping plates 16 to move horizontally towards each other, driving the two sliding plates 17 to clamp the cable protection pipe. The adjusting rod 111 is rotated, controlling the clamping plate 110 to drive the mounting rod 18 to move, so that the alarm 19 is against the inner wall of the cable protection pipe. When the rigidity of the cable protection pipe is tested, when the control motor 2 is started, the threaded rod 3 is driven to rotate and drive the moving plate 4 to move forward, the front end of the moving plate 4 directly contacts and presses against the pressure sensor 51 fixed on the left side of the extrusion plate 5, thereby applying an axial thrust to the pressure sensor 51. The insertion rod 41 is slidably inserted into the moving plate 4, and its front end is fixed to the extrusion plate 5, thereby ensuring the synchronization and guidance of the movement of the extrusion plate 5 and the moving plate 4, and assisting in driving or guiding the extrusion plate 5 to reset when the moving plate 4 retracts. The extrusion plate 5 moves within the space inside the mounting base 1, and its position is naturally constrained by the boundary of this space, causing the extrusion plate 5 and the arc plate 6 to move. The arc plate 6 then extrudes the cable protection pipe. At this time, the pressure sensor 51 will measure the pressure reading. When the cable protection pipe deforms, the alarm 19 will be compressed and trigger an alarm. By observing the reading of the pressure sensor 51, the stiffness of the cable protection pipe can be detected, achieving the effect of stabilizing the limit of the cable protection pipe and facilitating the detection of the specific load-bearing capacity of the cable protection pipe.

[0030] Working principle: When limiting the cable protection pipe, first place the cable protection pipe on the mounting base 1, then start the drive motor 14 to rotate the bidirectional threaded screw 15, controlling the two sliding plates 16 to move horizontally towards each other, driving the two sliding plates 17 to clamp the cable protection pipe. Rotate the adjusting rod 111 to control the clamping plate 110 to drive the mounting rod 18 to move, so that the alarm 19 is against the inner wall of the cable protection pipe. When testing the rigidity of the cable protection pipe, when the control motor 2 starts, drives the threaded rod 3 to rotate and drives the moving plate 4 to move forward, the front end of the moving plate 4 directly contacts and presses against the pressure sensor 51 fixed on the left side of the pressing plate 5, thereby applying an axial thrust to the pressure sensor 51. The insertion rod 41 is slidably inserted into the moving plate 4, and its front end is fixed to the pressing plate 5, thereby ensuring the synchronization and guidance of the movement of the pressing plate 5 and the moving plate 4, and assisting in driving or guiding the pressing plate 5 to reset when the moving plate 4 retracts. The extrusion plate 5 moves within the space inside the mounting base 1, and its position is naturally constrained by the boundary of the space, causing the extrusion plate 5 and the arc plate 6 to move. The arc plate 6 then extrudes the cable protection pipe. At this time, the pressure sensor 51 will measure the pressure reading. When the cable protection pipe deforms, the alarm 19 will be compressed and thus trigger an alarm. The rigidity of the cable protection pipe can be detected by observing the reading of the pressure sensor 51.
