[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a second conveyor belt, and since both the outer sides of the first and second conveyor belts are arc-shaped, it is beneficial to fit the cylindrical outer wall of the cable protection pipe, which greatly increases the contact area and avoids the pipe from tipping over or shifting during transportation.

[0010] 2. By setting up a connecting box with a pressure sensor inside, this utility model can monitor the clamping force of the two pairs of pipes on the conveyor belt in real time when connected to the control equipment.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0019] Example: As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a cable protection pipe cutting device, including a base plate 1, a support plate 2, and a positioning frame 4; The upper side of the base plate 1 is provided with an arc-shaped groove, and two sets of round holes are provided on the left and right sides of the base plate 1 respectively. A set of positioning bolts is installed in the two sets of round holes on the left and right sides of the base plate 1 respectively. The support plates 2 are placed on the upper left and right sides of the base plate 1 respectively. The support plates 2 are inclined and the bottom surface of the support plates 2 is fixedly connected to the top surface of the base plate 1. Two sets of electric push rods 5 are provided on the two sets of support plates 2 respectively. The positioning frame 2 4 is placed on the upper front side of the base plate 1. The movable frame 7 is provided inside the positioning frame 2 4. Two sets of sliders are provided on the left and right sides of the movable frame 7 respectively. The movable frame 7 has a groove on its inner side. A servo motor 8 is installed on the front side of the movable frame 7. The motor shaft of the servo motor 8 passes through the movable frame 7. The motor shaft of the servo motor 8 has a threaded hole. A saw blade 18 is installed on the motor shaft of the servo motor 8. The threaded hole on the motor shaft of the servo motor 8 is threaded with a fixing bolt 20. The fixing bolt 20 has an anti-loosening washer 19. An electric cylinder 6 is provided on the positioning frame 2 4. The push rod of the electric cylinder 6 is connected to the movable frame 7.

[0020] Among them, such as Figure 2 and Figure 3As shown, a conveyor belt 10 is provided on the upper rear end of the base plate 1, and the outer side of the conveyor belt 10 is arc-shaped. A set of connecting boxes 13 are connected to two sets of electric push rods 5 on the two sets of support plates 2. A set of pressure sensors is installed inside the two sets of connecting boxes 13, and a set of conveyor belts 14 is provided inside the two sets of connecting boxes 13. The outer side of the conveyor belts 10 and 14 is arc-shaped. Since the outer sides of both the conveyor belts 10 and 14 are arc-shaped, it is beneficial to fit with the cylindrical outer wall of the cable protection pipe, which greatly increases the contact area and avoids the pipe from tipping over or deviating during transportation. With the pressure sensor inside the connecting box 13, when this utility model is connected to the control equipment, it can monitor the clamping force of the conveyor belts 14 on the pipe in real time, automatically feed back and adjust the extension and retraction of the electric push rods 5, and avoid excessive pressure causing deformation and cracking of the non-metallic pipe, or loose clamping causing transportation deviation.

[0021] Among them, such as Figure 2 and Figure 4 As shown, a rubber pad A11 is provided on the upper front side of the base plate 1. The rubber pad A11 is arc-shaped, and a positioning frame 3 is connected to the upper end of the base plate 1. An electric cylinder 15 is installed on the upper end of the positioning frame 3. The push rod of the electric cylinder 15 passes into the interior of the positioning frame 3. A connecting plate 16 is connected to the push rod of the electric cylinder 15. A rubber pad B17 is provided on the lower side of the connecting plate 16. The lower side of the rubber pad B17 is arc-shaped and is placed on the upper side of the rubber pad A11. A shock-absorbing pad 12 is provided on the lower side of the base plate 1. Through the rubber pad A11... The 11 and rubber pad B17 are arc-shaped and fit the cylindrical outer wall of the cable protection pipe. The large contact area and uniform force are conducive to fixing the pipe and preventing slippage or displacement during cutting. At the same time, the rubber material is flexible and effectively buffers the clamping force, effectively preventing the pipe from deforming or cracking due to excessive clamping force. It is suitable for the clamping requirements of thin-walled protection pipes. The shock-absorbing pad 12 on the underside of the base plate 1 can absorb the high-frequency vibration generated by the servo motor 8 and saw blade 18 during the cutting process, preventing the vibration from being transmitted to the positioning structure and causing the pipe to shift, thus indirectly improving the cutting accuracy.

[0022] Among them, such as Figure 1 and Figure 5 As shown, the inner sides of the left and right ends of the positioning frame 2 4 are provided with two sets of sliding grooves, and the two sets of sliders on the left and right sides of the movable frame 7 are respectively placed inside the two sets of sliding grooves on the inner sides of the left and right ends of the positioning frame 2 4. The inner sides of the left and right ends of the positioning frame 2 4 are provided with a set of infrared sensors 9. Through the cooperation of the sliding grooves of the positioning frame 2 4 and the sliders of the movable frame 7, the movement of the movable frame 7 is limited, so as to avoid the saw blade 18 from deviating or tilting when it moves, ensuring that the cut is flat and perpendicular to the pipe axis, and ensuring the saw blade feed accuracy and stability. The infrared sensors 9 are used as anti-accidental touch sensors. When a human body or foreign object is detected to be close to the saw blade cutting area, the device is immediately triggered to stop, avoiding safety risks during the cutting process.

[0023] The specific usage and function of this embodiment are as follows: In this invention, by repeatedly squeezing the rubber ball 142, gas enters the pressure bag 10 through the rubber tube 141, causing the pressure bag 10 to expand. The pressure value is displayed on the electronic display screen 12 through the signal transmission of the pressure sensor 11 at the bottom. The pressure inside the pressure bag 10 is adjusted to a suitable value through the valve 143. The pressure bag 10 applies pressure to the plate 3, and the plate 3 squeezes the cotton wool in the groove 7 on the upper part of the fixed plate 6 connected to it. The medicine in the cotton wool is evenly applied to the patient's lesion through the injection hole 8, so that the fixed plate 6 performs pressure drug penetration therapy on the patient's lesion.
