Description

Technical Field

[0001] This utility model relates to the field of vibration detection technology for electromechanical equipment, specifically to a vibration detection device for electromechanical equipment. Background Technology

[0002] Vibration often occurs during the operation of electromechanical equipment. Vibration can easily cause the equipment to become unstable or malfunction, such as causing the balance point of the equipment to shift or damage the equipment. Unsmooth operation or malfunction of the equipment can easily lead to accidents. In order to avoid accidents, vibration testing is usually required before the electromechanical equipment is put into operation.

[0003] A search revealed a vibration detection device for coal mine electromechanical equipment disclosed in Chinese Patent Publication No. CN218524330U. This device utilizes a vibration motor to detect the vibration of the coal mine electromechanical equipment body by setting up a vibration component. When the vibration motor drives the placement plate to vibrate, the vibration spring deforms, increasing the up-and-down reciprocating vibration frequency of the placement plate. A vibration sensor module can then detect the vibration frequency of the coal mine electromechanical equipment body. After a specified vibration time, the vibration can be stopped, allowing for the testing of the mechanical properties of the equipment body. If the performance meets the standards, the coal mine electromechanical equipment body can be taken out of service.

[0004] However, the vibration detection device for coal mine electromechanical equipment can only perform fixed testing on specific models of electromechanical equipment, which leads to certain limitations in actual use. In addition, the device can only perform vibration detection on electromechanical equipment in one way. Therefore, a vibration detection device for electromechanical equipment is proposed.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 A vibration detection device for electromechanical equipment includes a base plate 1, a placement plate 2 is provided on the top of the base plate 1, a fixing structure 3 is provided on the outside of the placement plate 2, and a detection structure 4 is provided on the outside of the base plate 1. The fixed structure 3 includes a support plate 301. The support plate 301 is fixedly installed on the outer surface of the placement plate 2. A first telescopic rod 302 is fixedly installed on the outer surface of the support plate 301. A crossbar 303 is fixedly installed at the output end of the first telescopic rod 302. An electric slide rail 304 is fixedly installed inside the crossbar 303. A movable block 305 is provided on the outer surface of the electric slide rail 304. An extension block 306 is movably connected inside the movable block 305. An L-shaped rod 307 is fixedly installed on the top of the crossbar 303. A threaded rod 308 is threadedly connected to the top of the L-shaped rod 307. A top plate 309 is rotatably connected to the bottom of the threaded rod 308.

[0018] Furthermore, the detection structure 4 includes a vibration motor 401, the vibration motor 401 is fixedly installed on the outer surface of the support plate 301, a second telescopic rod 402 is fixedly installed inside the placement plate 2, a drawing pen 403 is fixedly installed at the end of the second telescopic rod 402, a U-shaped block 404 is fixedly installed on the left side of the placement plate 2, a drawing board 405 is inserted into the U-shaped block 404, a spring body 406 is fixedly installed on the top of the base plate 1, and a limit rod 407 is fixedly installed on the bottom of the placement plate 2.

[0019] Specifically, such as Figure 1 As shown, all electrical components of the device are controlled via an external control panel. The control panel is electrically connected to the electrical components. After placing the device to be tested in the center of the placement plate 2, the length of the extension block 306 protruding from the movable block 305 is adjusted according to the size of the device and fixed with bolts. Then, opening the first telescopic rod 302 will move the two crossbars 303 closer together, clamping and fixing the front and rear sides of the device. Next, the four electric slide rails 304 are opened, which can move the four movable blocks 305 in opposite directions. Thus, the movable blocks 305, in conjunction with the extension block 306, clamp and fix the left and right sides of the device. Finally, rotating the threaded rod 308 will move the top plate 309 downward, clamping and fixing the top of the device. Through clamping and fixing in three directions, it is ensured that the device will not shift during the testing process, which could lead to inaccurate testing.

[0020] Specifically, such as Figure 3 and Figure 6As shown, after the electromechanical equipment is fixed, the detection method is selected according to the actual practical needs. The drawing board 405 is inserted into the inside of the U-shaped block 404. Then, opening the second telescopic rod 402 will drive the drawing pen 403 to move closer to the drawing board 405 until it is in contact with it. The drawing pen 403 is an erasable drawing pen. Then, the electromechanical equipment is turned on. After the electromechanical equipment is started, it will generate vibration force. This vibration force will drive the placement plate 2 and the limiting movable rod 407 to move up and down. During the movement of the placement plate 2, it will squeeze or extend the spring body 406. The limiting movable rod 407 will be limited inside the base plate 1. The device moves within the movable slot, thereby moving the drawing pen 403 along with the placement plate 2. Employees can then slowly and uniformly pull the drawing plate 405 to display the vibration data and direction of the electromechanical equipment using the drawing pen 403, facilitating observation. After use, the drawing plate 405 can be wiped clean for reuse. Alternatively, the vibration motor 401 can be turned on to drive the placement plate 2 and the electromechanical equipment for vibration testing. After a period of vibration, the vibration motor 401 can be turned off to test the mechanical performance of the electromechanical equipment.

[0021] Specifically, such as Figure 2 As shown, the main components of the electric slide rail 304 include a power supply, a motor, a driver, a controller, a transmission mechanism, and the slide rail itself, which includes a track and sliding blocks. Its working principle is as follows: the power supply provides electrical energy to the entire system; the motor, as the power source, is driven to rotate by the driver under the command of the controller; and the transmission mechanism is responsible for converting the rotational motion of the motor into the linear motion of the sliding blocks on the slide rail. Common transmission mechanisms include precision mechanical structures such as worm gears, lead screws, and nuts. During operation, the controller precisely controls the motor's speed, direction, and working time according to a preset program or external signals, thereby driving the sliding blocks to slide smoothly and accurately on the track. This motion method has high precision and stability, meeting the linear motion requirements of various automated equipment and precision machinery. Furthermore, the electric slide rail 304 is equipped with limit devices and safety protection devices to ensure that the sliding blocks move within a specified range and can quickly stop movement in case of abnormal conditions, thus protecting the safety of equipment and operators. At the same time, the maintenance and upkeep of the electric slide rail 304 are relatively simple; only regular inspection and lubrication are needed to ensure its long-term stable operation.

[0022] In summary, this vibration detection device for electromechanical equipment allows for the placement of the equipment to be tested in the center of the placement plate 2 during testing. The fixing structure 3 secures the equipment by clamping it in the front, back, left, right, and top / bottom positions, facilitating the fixation of equipment of different sizes. After fixation, the detection structure 4 enables vibration detection of the equipment using two methods, thus improving the device's practicality during use.
