Description

Technical Field

[0001] The present invention relates to the technical field of barring gears, and specifically to a new type of barring gear device. Background Technique

[0002] The barring gear is a very crucial device during the installation and maintenance process of the unit. When the unit is under maintenance, it is necessary to drive the rotor to rotate through multiple barring operations, and important data such as the swing, level, axis, rotor roundness, and stator roundness of the rotating part of the unit are collected through the unit.

[0003] After retrieval, a Chinese utility model patent with the application number "202221843202.9" and the name of an intelligent barring gear device for a hydro-generator set discloses that the intelligent barring gear device includes a base and an external gear ring installed on the base. The external gear ring is located outside the transition shaft installed on the hydro-generator set and is coaxial with it. A number of pawls are evenly distributed in a circle on the external gear ring, and the pawls respectively extend into the tooth grooves on the outer circumference of the transition shaft. When the external gear ring rotates, the transition shaft is driven to rotate through the pawls; a cross bar is installed on each pawl; the cross bar on the pawl is located in the tooth groove corresponding to the pawl, rotates together with the pawl, and one end abuts against the side wall of the tooth groove corresponding to the pawl. A pressure sensor is installed between them, and the gap between the two is adjusted through an adjustment mechanism. This device reads the pressure through the additional pressure sensors, and adjusts the gap based on this to ensure that the forces on each pawl are uniform and avoid the problem of breakage of one or several pawls. However, the overall structure of this device is relatively large, and a hoisting device is required to install the base on the outside of the hydro-generator set during installation, which requires a large amount of manpower and material resources. Moreover, after the device is installed, it is impossible to collect data such as the axis and swing of the air supply pipe, and another set of sub-devices is required for collection. When the sub-devices are used for collection, they need to be installed at multiple points in sequence to pull the generator set, and the process is complicated and the collection trajectory is not continuous.

[0004] Therefore, a new type of barring gear device is needed to improve the above problems. Summary of the Invention

[0029] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0030] Embodiment 1, please refer to Figure 1 , 2, 3, and 4, a new type of barring gear, including a mounting frame body, which is arranged below the brake ring 2; a driving wheel structure is installed at the upper end of the mounting frame body, a driving member is installed in the middle of the mounting frame body, and the output end of the driving member is connected to the driving wheel structure through a lifting mechanism. The driving member drives the driving wheel structure to adjust its height in the vertical direction, driving the driving wheel structure to abut against or separate from the lower surface of the brake ring 2. When the driving wheel structure abuts against the lower surface of the brake ring 2, it drives the rotor 2 to rotate for data collection.

[0031] The overall volume of this device is relatively small. Multiple devices can be set below the generator rotor 2, limitedly arranged between two brake seats 21, and limited and fixed through a docking structure. The relatively small volume enables the device to be installed and disassembled conveniently. Compared with the comparative case, the installation and use of this device do not require the assistance of a hoisting device, reducing the investment in manpower and material resources and lowering the maintenance cost. The driving member adopts a servo hydraulic cylinder or an electric mechanism;

[0032] This device abuts against the bottom end of the engine rotor 2 through the driving wheel structure, drives the engine rotor 2 to rotate through the driving wheel structure, and installs multiple acquisition devices on the side of the engine rotor 2 for data acquisition. In the comparative case, it is impossible to collect data such as the axis of the make-up air pipe and the swing. After installing the base, additional sub-devices need to be used for collection. However, with the use of this device, multiple groups of detection devices can be installed at one time to collect multiple data, simplifying the detection steps and reducing the maintenance cost. The driving wheel structure can be driven by the driving member for clearance adjustment, and the pressure sensor 18 can detect the magnitude of the force applied to the surface of the driving wheel structure and the engine rotor 2 for adjustment.

At the same time, the driving rod can also adopt a pneumatic telescopic rod. The hydraulic telescopic rod is externally connected to a hydraulic system through a pipeline for centralized control.

[0035] The lifting mechanism adopts a hydraulic telescopic rod, a pneumatic or an electric telescopic rod, and the driving device adopts an electric or a hydraulic drive wheel. The lifting mechanism is provided with pressure and distance sensors, which can adjust and monitor the contact force and distance between the new type of turning device and the brake ring in real time.
