Description

Technical Field

[0001] This utility model belongs to the field of probe installation technology, specifically relating to a probe installation structure for safety detection of rotating machinery. Background Technology

[0002] Safety inspection of rotating machinery is a key link in ensuring the stable operation of equipment and the safety of operators. It involves the application of multi-dimensional detection methods and technologies. Vibration monitoring and protection instruments, as detection equipment, are used to continuously monitor and measure the vibration and speed of the rotating shaft of rotating machinery, so that users can understand the operating conditions of the machine.

[0003] Existing vibration monitoring and protection devices use probes to detect the rotating shaft of rotating machinery. As independent probes, they need to be installed with the help of brackets. Moreover, since the probes need to be perpendicular to the detection surface of the rotating shaft, it is difficult to accurately install the probes at the required detection points.

[0004] Therefore, a probe mounting structure for safety detection of rotating machinery is proposed. Summary of the Invention

[0005] This invention provides a probe mounting structure for safety detection of rotating machinery, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a probe mounting structure for safety detection of rotating machinery, including an adjusting frame; a bidirectional lead screw rotating on the inner side wall of the adjusting frame; two movable stages symmetrically arranged on the bidirectional lead screw; a T-shaped slot on one side wall of the movable stage; a T-shaped plate inserted into the T-shaped slot; a slot on one side outer wall of the T-shaped plate; a plug plate inserted into the slot; a probe mounting seat located at the center of one side outer wall of the adjusting frame; a probe fixed to the probe mounting seat by bolts; a first fastening plate and a second fastening plate located on the other side outer wall of the adjusting frame, the first fastening plate being located on one side of the second fastening plate; and a fastening screw threaded onto one side wall of the first fastening plate, the fastening screw passing through the second fastening plate.

[0007] Furthermore, the outer walls of the fastening plates 1 and 2 facing each other are provided with arc-shaped portions, and a support rod passes through between the two arc-shaped portions. One end of the support rod is fitted with a rod sleeve, and a tightening screw is threadedly connected to one side of the outer wall of the rod sleeve. A base is provided at the bottom end of the rod sleeve.

[0008] Furthermore, a rotating shaft is provided between the two T-shaped plates near the side of the stopper plate.

[0009] Furthermore, the cross-section of the moving platform is an "I" shaped structure, and the moving platform and the adjustment frame are slidably connected;

[0010] By adopting the above technical solution, the "I"-shaped moving platform forms a limit between itself and the adjusting frame, thereby ensuring the stability of the moving platform's movement along the adjusting frame, and thus enabling stable adjustment of the distance between the two moving platforms.

[0011] Furthermore, the two T-shaped plates are parallel, and the plug plate is perpendicular to the T-shaped plates;

[0012] By adopting the above technical solution, two parallel T-shaped plates can be adjusted according to the outer diameter of the rotating shaft to ensure that the probe is in the middle position of the rotating shaft and that the probe coincides with the axis of the rotating shaft, thereby making the probe perpendicular to the detection surface of the rotating shaft.

[0013] Furthermore, the probe and the plug plate abut against each other;

[0014] By adopting the above technical solution, the probe and the plug plate can be made to be without gaps. The thickness of the plug plate is the distance between the probe and the rotating shaft, which makes it easy to control the detection gap within the required range.

[0015] Furthermore, both of the T-shaped plates are attached to the outer circumferential surface of the rotating shaft;

[0016] By adopting the above technical solution, the outer diameter of the rotating shaft can be adjusted to ensure that the probe is located at the axis of the rotating shaft.

[0017] Furthermore, the support rod has an L-shaped structure;

[0018] By adopting the above technical solution, a portion of it can be made parallel to the horizontal plane, thereby providing better support for the adjustment frame.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model uses an installation auxiliary positioning structure consisting of two T-shaped plates with adjustable spacing and a plug plate, which allows the probe to be installed at the required detection position on the rotating shaft. This not only makes the probe axis perpendicular to the rotating shaft, improving the detection accuracy, but also controls the detection gap between the probe and the rotating shaft within the required range, further improving the detection accuracy and achieving probe positioning and installation.

[0021] 2. This utility model uses a support and adjustment assembly formed by fastening plate one, fastening plate two, and support rod to adjust the angle of the adjustment frame so that it can be set in the required position, thereby improving the flexibility of probe installation.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] Example 1

[0031] Reference Figure 1-4This utility model embodiment proposes a probe mounting structure for safety detection of rotating machinery, including an adjusting frame 1. A bidirectional lead screw 2 is rotatably connected to one inner wall of the adjusting frame 1. The bidirectional lead screw 2 has symmetrical left-hand and right-hand threads, and two moving platforms 3 are symmetrically arranged on the outer wall of the bidirectional lead screw 2. The cross-section of the moving platform 3 is "I". The moving platform 3 and the adjusting frame 1 are slidably connected. The "I"-shaped moving platform 3 forms a limit between itself and the adjusting frame 1, thereby ensuring the stability of the moving platform 3 moving along the adjusting frame 1. In addition, the distance between the two moving platforms 3 can be stably adjusted. A T-shaped slot 4 is opened on one outer wall of each of the two moving platforms 3. A T-shaped plate 5 is inserted into the T-shaped slot 4. The two T-shaped plates 5 are parallel, and the plug plate 7 is perpendicular to the T-shaped plates 5. The two parallel T-shaped plates 5 can be used to adjust according to the outer diameter of the rotating shaft 17 to ensure that the probe 9 is in the rotating position. The rotating shaft 17 is positioned at the middle, ensuring that the axis of the probe 9 is perpendicular to the axis of the rotating shaft 17 and that the probe 9 is perpendicular to the detection surface of the rotating shaft 17. Slots 6 are provided on one outer wall of each of the two T-shaped plates 5, and plug plates 7 are inserted into the two slots 6. A probe mounting seat 8 is located at the center of one outer wall of the adjusting frame 1, and the probe 9 is fixedly connected to the probe mounting seat 8 by bolts. The probe 9 and the plug plate 7 abut against each other, ensuring no gap between them. The thickness of the plug plate 7 is the distance between the probe 9 and the rotating shaft 17, facilitating control of the detection gap within the required range (generally 0.5-1.5mm). The rotating shaft 17 is located between the two T-shaped plates 5 near the plug plate 7, with both T-shaped plates 5 fitting against the outer circumference of the rotating shaft 17. This allows for adjustment based on the outer diameter of the rotating shaft 17, ensuring that the probe 9 is positioned at the axis of the rotating shaft 17.

[0032] Specifically, when installing the probe 9, first install the adjustment frame 1 according to the position of the rotating shaft 17, insert one end of the T-shaped plate 5 into the T-shaped slot 4, connect the T-shaped plate 5 and the moving stage 3, the two T-shaped plates 5 form the rotating shaft 17 detection structure, and insert the plug plate 7 into the slot 6 on the two T-shaped plates 5.

[0033] Place the plug plate 7 on the outer circumferential surface of the rotating shaft 17. Then, rotate the double-acting screw 2. After the double-acting screw 2 rotates, the two moving stages 3 on the double-acting screw 2 move towards each other. As the moving stages 3 move, the T-shaped plates 5 on the moving stages 3 move synchronously. After the two T-shaped plates 5 move towards each other, they fit against the outer circumferential surface of the rotating shaft 17, thus positioning the adjustment frame 1. At this time, install and fix the adjustment frame 1. Then, remove the T-shaped plates 5 and the plug plate 7, and install and fix the probe 9 on the probe mounting base 8, thus installing the probe 9 and ensuring that the probe 9 is in the optimal detection position.

[0034] Example 2

[0035] Reference Figure 1-3Based on the above embodiments, this utility model embodiment also proposes a probe installation structure for rotating machinery safety detection, including an adjustment frame 1. A fastening plate 10 and a fastening plate 11 are provided on the outer wall of the other side of the adjustment frame 1. The fastening plate 10 is located on one side of the fastening plate 11, and a fastening screw 12 is connected to one side of the outer wall of the fastening plate 10 by a thread. The fastening screw 12 passes through the fastening plate 11, and one end of the fastening screw 12 is provided with a screw head. Both the outer walls of the fastening plate 10 and the fastening plate 11 are provided with arc-shaped parts, and a support rod 13 passes through the two arc-shaped parts. The support rod 13 has an L-shaped structure, which can make part of it parallel to the horizontal plane, thereby better supporting the adjustment frame 1. One end of the support rod 13 is fitted with a rod sleeve 14, and a tightening screw 15 is connected to one side of the outer wall of the rod sleeve 14 by a thread. A base 16 is provided at the bottom end of the rod sleeve 14.

[0036] Specifically, in order to fix the position of the adjustment frame 1 after adjustment, in this embodiment, after the adjustment frame 1 is adjusted to the required position, the fastening screw 12 is rotated. Through the threaded connection between the fastening screw 12 and the fastening plate 10, the screw head of the fastening screw 12 presses against the fastening plate 11 during rotation, the distance between the fastening plate 10 and the fastening plate 11 becomes smaller, and a compressive force is formed between the fastening plate 10 and the fastening plate 11, which clamps onto the support rod 13, thereby fixing the position of the adjustment frame 1. Then, the rod sleeve 14 is pulled down so that the base 16 at the bottom of the rod sleeve 14 contacts the equipment and is installed and fixed, thus completing the support of the adjustment frame 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
