Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline endoscopes, in particular to a variable auxiliary pulley for pipeline endoscopes. Background Art
[0002] In the prior art, pipeline endoscopes are a commonly used tool for inspecting and maintaining the interior of pipelines. Existing pipeline endoscopes cannot be adjusted to accommodate pipelines of different diameters, which limits their applicability in variable pipeline environments. During pipeline inspection, existing endoscope cameras are placed close to the inner wall of the pipeline, resulting in a limited field of view, making it impossible to fully observe the interior of the pipeline, and defects or obstacles are easily missed. The camera being too close to the inner wall will cause image distortion, reducing image clarity and accuracy, and affecting the reliability of the inspection results. This increases the resistance of the endoscope when advancing in the pipeline, especially in curved or narrow sections of the pipeline, which may prevent the endoscope from passing smoothly, thereby increasing the difficulty of operation. Because the camera cannot be centered, additional time is required to adjust the position and angle of the endoscope, which reduces inspection efficiency. Frequent repairs or replacements of the camera will also increase maintenance costs, and the camera may touch sharp objects or harmful substances in the pipeline, reducing the lifespan of the endoscope camera. This limits the effectiveness and safety of existing endoscope cameras in pipeline inspections. Therefore, the existing technology has deficiencies in adaptability, stability and flexibility, and a new pipeline endoscope auxiliary pulley structure is needed to improve its applicability and reliability in complex pipeline environments.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] See also Figures 1 to 4 The utility model provides a technical solution: a variable auxiliary pulley 9 of a pipeline endoscope, comprising: a central column 1, a fixed support frame 2, a thread 3, an adjustment mechanism, an expansion mechanism and a fixing mechanism, the fixed support frame 2 is mounted on the outer side of the outer wall of the central column 1; the thread 3 is opened on the outer side of the outer wall of the central column 1; the adjustment mechanism is respectively arranged on the fixed support frame 2 and the thread 3; the expansion mechanism is movably mounted on the outer side of the adjustment mechanism and the fixed support frame 2; the fixing mechanism is arranged at the end of the central column 1.
[0018] It should be noted that the adjusting mechanism can drive the expansion mechanism to move by rotating on the thread 3 to adapt to pipes of different diameters. When the adjusting mechanism is adjusted, the expansion mechanism moves accordingly to adapt to changes in the pipe diameter. The fixing mechanism is provided at the end of the central column 1 and is used to fix the endoscope camera to ensure that the camera can work stably in the pipe. By adjusting the adjusting mechanism, the fixed support frame 2 and the expansion mechanism can adapt to different pipe sizes. At the same time, the fixing mechanism ensures the stability of the camera, so that the pipeline endoscope can smoothly perform detection and dredging work in the pipe.
[0019] In some examples, the adjustment mechanism includes: a hand-tightening nut 4, a movable support frame 5 and a hinge seat 6, the hand-tightening nut 4 is screwed onto the thread 3 on the outside of the outer wall of the center column 1; the movable support frame 5 is rotatably connected to the hand-tightening nut 4; and several hinge seats 6 are respectively installed on the outside of the outer walls of the fixed support frame 2 and the movable support frame 5.
[0020] It should be noted that when the position of the mobile support frame 5 needs to be adjusted, the user can do so by manually rotating the hand nut 4 to move on the thread 3. As the hand nut 4 rotates, the mobile support frame 5 rotatably connected thereto will also move. The mobile support frame 5 and the hand nut 4 can be connected by interference fit or bearing. The function of the hinge seat 6 is to allow the bracket 8 to rotate flexibly when the mobile support frame 5 moves with the hand nut 4, so as to achieve the effect of adjusting the diameter. By rotating the hand nut 4, the mobile support frame 5 moves on the central column 1 along the thread 3, thereby driving the mobile support frame 5 to achieve the extension or contraction of the entire expansion mechanism to adapt to the fixation and support requirements of pipeline endoscope cameras of different sizes. It ensures that the pipeline endoscope camera can maintain a stable and centered position in pipelines of different diameters, so as to carry out effective detection and dredging work.
[0021] In some examples, a spring 7 is further installed between the fixed support frame 2 and the movable support frame 5. The spring 7 provides an adjustable tension to ensure that the support frame can maintain appropriate pressure and stability when the pipeline endoscope camera is fixed. When the hand-tightening nut 4 moves, the movable support frame 5 moves closer to or away from the fixed support frame 2. The spring 7 is compressed or stretched in this process, thereby generating a reaction force, which can help the fixed support frame 2 and the movable support frame 5 to cooperate closely, ensuring that the camera maintains a stable position in the pipeline and preventing the camera from shifting due to bending or unevenness of the pipeline. This allows the pipeline endoscope camera to move more smoothly in the pipeline, improving the efficiency of detection and dredging.
[0022] In some examples, the expansion mechanism includes: a bracket 8 and a pulley 9, wherein a plurality of brackets 8 are arranged in a group of two, and one end is rotatably arranged on a plurality of hinge seats 6; wherein the middle parts of the two brackets 8 in each group are rotatably connected by a pin shaft; and a plurality of pulleys 9 are rotatably arranged in a group of two on the other end of the plurality of brackets 8.
[0023] It should be noted that the bracket 8 is connected to the hinge seat 6 so that the bracket 8 can rotate with the movement of the movable support frame 5. The middle parts of the two brackets 8 in each group are connected by a pin, which allows the bracket 8 to be flexibly adjusted to adapt to the diameter of the pipe when the pipeline endoscope camera moves. The pulley 9 is used to reduce the resistance of the pipeline endoscope camera when it moves in the pipe, so that the camera can move forward or backward more smoothly in the pipe. When the hand-tightening nut 4 is rotated, the relative position of the fixed support frame 2 and the movable support frame 5 changes, realizing the synchronous movement and adjustment of the bracket 8 and the pulley 9, ensuring that the pipeline endoscope camera moves stably and flexibly in the pipe, while reducing friction and wear, and improving the efficiency of detection.
[0024] In some examples, the fixing mechanism includes: an inner hole 10 and a screw 11. The inner hole 10 is opened at the end of the center column 1; a plurality of screws 11 are respectively screwed to the outer side of the outer wall of the center column 1 and respectively penetrate into the inner hole 10. The inner hole 10 is used to accommodate and fix the endoscope camera. The screw 11 passes through the outer wall of the center column 1 and penetrates into the inner hole 10 so as to directly contact the endoscope camera. When the endoscope camera needs to be fixed, the screw 11 is screwed into the inner hole 10 and contacts the camera to achieve the tightening of the camera. The endoscope camera is allowed to be firmly fixed at the end of the center column 1. The adjustability of the screw 11 also allows the camera to be fine-tuned as needed. The inner hole 10 can match endoscope cameras of Φ37mm / Φ32mm / Φ23mm / Φ22mm sizes and is fixed by the screw 11, ensuring the stability and reliability of the endoscope camera during pipeline inspection or dredging operations, and providing a solid foundation for the efficient operation of the pipeline endoscope.
[0025] In some examples, each set of brackets 8 is divided into an outer angle 81 and an inner angle 82, and the angle of the outer angle 81 is greater than the angle of the inner angle 82. When the mobile support frame 5 needs to move toward the fixed support frame 2 to adjust the camera position, the outer angle 81 is greater than the inner angle 82, which allows the mobile support frame 5 to push the two brackets 8 to rotate crosswise more smoothly.
