[0004] In the above technical solution, the parts to be tested need to be moved to a certain height before being assembled with the power output shaft. This greatly increases the difficulty of installing the object being tested during the assembly process. In addition, the drive wheel or other parts to be tested have a certain weight, and it is difficult to complete the assembly by manual handling, which is time-consuming and labor-intensive. Utility Model Content

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0022] Example 1:

[0023] refer to Figure 1 A drive wheel vibration detection device includes a base 10 and a control panel 11. A power output shaft 12 is located on one side of the control panel 11, and a vibration acceleration sensor 14 is located above the power output shaft 12.

[0024] The control panel 11 is equipped with a corresponding electronic display screen and mechanical control buttons. The control panel 11 is used to output commands and read and analyze data. Inside the control panel 11 is a motor that drives the power output shaft 12 to rotate. This motor can be any motor capable of driving the power output shaft 12 to rotate; motors are readily available on the market. The contact end of the vibration acceleration sensor 14 is near the power output shaft 12. A drive wheel to be measured is mounted on the power output shaft 12. Under the influence of the drive wheel, the power output shaft 12 rotates at high speed. When there are parts of different weights on the drive wheel, it will cause the power output shaft 12 to generate vibration amplitude. The vibration acceleration sensor 14 is an important tool for measuring mechanical vibration parameters. Its working principle is based on the piezoelectric effect. The piezoelectric effect refers to the change in size of certain crystals (such as quartz, ceramics, etc.) under external force, and this change in size is converted into electric charge. Accelerometers utilize this effect to measure the acceleration of an object in a certain direction. When the vibration accelerometer comes into contact with the surface of the object being measured, or is connected to the object in some way (such as by fixing it to a bearing), the piezoelectric material in the sensor deforms with the vibration of the object. This deformation generates an electric charge, which is converted into a voltage signal by a charge amplifier. Finally, the data is processed by a data acquisition system to obtain the vibration of the object. The electrical signal of the vibration accelerometer 14 is connected to the control panel 11, and its data is displayed on the electronic display screen as test parameters.

[0025] Preferred solution reference Figure 1 An extension plate 13 is fixed to the top of the control panel 11, and the vibration acceleration sensor 14 is detachably mounted on one end of the extension plate 13. The detachable mounting method adopts a threaded connection, which can be rotated and adjusted to facilitate the adjustment of the height of the vibration acceleration sensor 14.

[0026] refer toFigure 1 and Figure 2 A load-bearing plate 20 is installed above the base 10. A fixed clamping block 201 and a first cylinder 204 are fixed on the surface of the load-bearing plate 20. A movable clamping block 202 is corresponding to one side of the fixed clamping block 201. A connecting arm 203 is fixed on one side of the movable clamping block 202. The output end of the first cylinder 204 is connected to the connecting arm 203.

[0027] In the above scheme, based on Figure 2 In the diagram, the dotted line represents the horizon, and the base 10 is located below ground level. The drive wheel is installed as follows: It is moved to the surface of the load-bearing plate 20 by rolling, between the fixed clamping block 201 and the movable clamping block 202. Then, the first cylinder 204 is activated via the control panel 11. The first cylinder 204 transmits thrust to the connecting arm 203, which in turn moves the movable clamping blocks 202 at both ends, causing them to press against the drive wheel, thus clamping the drive wheel on the surface of the stabilizing column base 10 and preventing wobbling during installation. The first cylinder 204 is electrically connected to the control panel 11.

[0028] The opposing surfaces of the fixed clamping block 201 and the movable clamping block 202 are covered with protective rubber. The protective rubber acts as a buffer, preventing the fixed clamping block 201 and the movable clamping block 202 from damaging the outer wall of the drive wheel, while also improving the anti-slip effect.

[0029] Example 2:

[0030] The load-bearing plate 20 has extended arms 205 on both sides, and a lifting and adjusting component is located below the extended arms 205.

[0031] The extended arm 205 is positioned close to the outer wall of the control panel 11;

[0032] The lifting and adjusting assembly includes a second cylinder 302. A horizontal plate 301 is fixed to the output end of the second cylinder 302. Pads 30 are fixed to both ends of the horizontal plate 301. The pads 30 are fixed to the lower part of the extension arm 205.

[0033] In the above scheme, after the drive wheel on the surface of the load-bearing plate 20 is clamped and stabilized by the fixed clamping block 201 and the movable clamping block 202, the second cylinder 302 (electrically connected to the control panel 11) is activated. The output end of the second cylinder 302 will lift the extension arm 205, that is, the load-bearing plate 20 will rise accordingly, and the position of the drive wheel will be adjusted to the concentric position with the power output shaft 12, so as to facilitate the staff to perform assembly and testing operations on the drive wheel.

[0034] Reference in the preferred solution Figure 4 A slide rod 304 is fixed to the inner wall of the base 10, and a side lug 303 is fixed to the side of the second cylinder 302. The side lug 303 is slidably mounted on the slide rod 304.

[0035] In the preferred embodiment, the second cylinder 302 can move freely on the slide bar 304 through the side lug 303, that is, the load-bearing plate 20 can move back and forth. After the position of the drive wheel is adjusted to be concentric with the power output shaft 12, the back and forth direction is adjusted by pushing the load-bearing plate 20, so that the drive wheel is disengaged from the power output shaft 12 or the drive wheel is disengaged from the power output shaft 12.

[0036] More specifically, when disassembling the drive wheel, the load-bearing plate 20 needs to be moved first to disengage the drive wheel from the power output shaft 12, and then the second cylinder 302 is activated to lower the load-bearing plate 20 to the ground level. Figure 2 (The dotted line in the image); then start the first cylinder 204, causing the movable clamp 202 to release its grip on the drive wheel; finally, help the drive wheel roll away from the load-bearing plate 20; conversely, install the drive wheel by repeating the opposite steps. In this way, whether disassembling or installing the drive wheel, the operator does not need to manually lift it and install it on the power output shaft 12, saving time and effort and reducing the workload of the operator.

[0037] The specific implementation process of this utility model is as follows:

[0038] The rolling drive wheel moves it to the surface of the load-bearing plate 20, between the fixed clamping block 201 and the movable clamping block 202; then, the first cylinder 204 is activated by the control panel 11, and the movable clamping block 202 presses against the drive wheel to clamp the drive wheel on the surface of the stabilizing column base 10; the second cylinder 302 is activated, and the output end of the second cylinder 302 will push up the extension arm 205, that is, the load-bearing plate 20 will rise accordingly, adjusting the position of the drive wheel to a concentric position with the power output shaft 12; the load-bearing plate 20 is moved so that the drive wheel and the power output shaft 12 are assembled.
