technical field

The present invention relates to an equipment leveling device, in particular to a suspension equipment leveling device.

the

Background technique

Most of the suspended equipment is the operating mechanism of the main equipment of the power grid, and the quality of its installation process directly affects the healthy operation of the equipment. For example, the improper installation position of the mechanism box of the isolating switch will cause the main shaft of the isolating switch to bear radial stress. When the motor rotates, it will generate a torque on the main shaft, which will cause plasticity of the main shaft or other weak transmission parts after long-term operation. out of shape. As a result, the opening and closing operations of the isolating switch are not in place and the fixing parts at both ends of the main shaft are worn out, which will endanger the safe operation of the equipment. Taking Quanzhou Electric Power Bureau as an example, from 2006 to 2010, 261.8 sets of isolating switches were added every year; 2,000 sets of isolating switches in operation, the maximum operating life of the knife switch is 20 years, and the average annual number of technical transformation and replacement is 100 sets, so every year About 361.8 sets of isolating switches need to be installed, which is an important part of a maintenance work. As the power source of the isolating switch, the installation process of the mechanism box directly affects the healthy operation of the equipment. At present, there are many ways to install the operating mechanism of the isolating switch, and each construction team does not have a standard. There are wooden boxes under the mechanism box, hydraulic forklifts and various plugging objects to fix it; the mechanism box is hung on the main shaft of the isolating switch with a rope. On, and then artificially corrected and so on. These installation methods cannot accurately meet the installation accuracy of the mechanism box in the three axial positions of the space, and have a low safety factor, easy damage to equipment components, cumbersome installation procedures, low work efficiency, and waste of manpower and material resources.

Contents of the invention

The object of the present invention is to overcome the shortcomings of the prior art, and provide a suspension leveling device with high installation precision, high safety factor, simple installation process, high work efficiency and low cost of use.

A leveling device for suspension equipment, including a panel and four legs, the panel is supported on the four legs, each leg includes a motor fixing box, a motor, a ball screw pair, and a cylindrical leg. The motor fixing box described above is fixed on the end of the bottom surface of the sliding screw seat fixing plate, the motor is arranged in the motor fixing box through the motor fixing frame installed in the motor fixing box, and the screw rod in the ball screw pair is connected with the The main shaft of the motor is connected, and a screw pair is provided in the inner cavity of the cylindrical support leg. The screw rod in the ball screw pair passes through the motor box and extends into the screw pair in the cylindrical support leg. The support leg also includes There is a guide rod, the guide rod is parallel to the cylindrical support leg, the upper end of the guide rod is connected to the motor box through the fixed frame fixed to the motor box to move up and down with the motor box, and the cylindrical support leg is also provided with A guide plate through which the guide rod passes, a virtual leg detection switch is provided at the bottom of each leg, a biaxial inclination sensor is provided at the center of the bottom surface of the panel, and the suspension equipment leveling device also includes: A control system, the control system is used to control the action of the motor and receive signals from the biaxial inclination sensor and the virtual leg detection switch.

The automatic adjustment device for suspended equipment of the present invention realizes the adjustment of the height direction of the panel through the lifting legs, and at the same time, by setting a dual-axis inclination sensor at the bottom of the panel, and setting a virtual leg detection switch at the bottom of the legs, the double The information of the shaft inclination sensor and the virtual leg detection switch is transmitted to the control system, and then the control system controls the action of the motor to realize the adjustment of the levelness.

A limit switch induction plate is arranged at the bottom of the guide rod, and a limit switch is arranged near the guide rod on the lower surface of the guide plate.

By setting the limit switch on the lower surface of the guide plate, and setting the limit switch induction plate on the guide rod, it can prevent the situation that the supporting leg should be adjusted too high and come out upward when adjusting.

A threaded connector for connecting the two is also arranged between the guide plate and the fixing frame.

A threaded connection between the two can further enhance the stability of the leg.

An induction plate is arranged at the upper position of the guide rod between the guide plate and the fixed frame, and a limit switch is arranged on the threaded connection between the guide plate and the fixed frame.

The motor is a stepper motor.

The control system includes a single-chip microcomputer, a display screen, a virtual leg detection switch, a limit switch, a stepper motor driver, a stepper motor, a biaxial inclination sensor and a display screen, a virtual leg detection switch, a limit switch and a biaxial inclination angle sensor. The sensor transmits the collected signal to the single-chip microcomputer, the single-chip microcomputer is connected with the display screen, and the single-chip microcomputer is connected with the stepping motor driver to drive the stepping motor to act through the stepping motor driver.

The stepping motor driver is a dual-axis stepping motor driver, and one stepping motor driver drives the stepping motors in the two supporting legs to move.

The method for the single-chip microcomputer to control the action of the stepping motor is to adjust the highest support point of the panel in a chasing and leveling manner in which the other three support points are aligned to it.

The specific adjustment method of the outriggers is to use the leveling method of raising the outriggers in one direction, that is, the highest point of the platform is not determined, and the method of leveling in the order of the X direction and the Y direction is used. When leveling, only adjust The lower side in each direction, specifically, adjust the level of the X direction first, and judge the inclination angle α measured by the level sensor of the dual-axis inclination sensor. If α<0, it can be known that the positive direction of the X-axis is lower than the negative direction, and fix A Keep the points B and D fixed, raise the points B and C, that is, let BC rotate counterclockwise with AD as the axis, so that the value of the inclination α gradually decreases until the accuracy requirements are met, that is, the X direction reaches the level, and vice versa Fix BC and let AD rotate clockwise around BC so that the value of inclination α meets the accuracy requirements, and then adjust the level of Y direction, the method is the same as that of X direction, where ABCD are the four corners of the panel.

The described leveling method is that the X direction and the Y direction are repeatedly adjusted repeatedly.

With the above leveling method, even if there is interference or the highest point of the platform changes due to coupling, the purpose of leveling can be achieved through unidirectional quadratic adjustment. The one-way raising outrigger leveling strategy is actually an improvement of the chasing method. This leveling method strictly follows the principle that the outriggers only rise but not lower during the leveling process, ensuring the stability and accuracy of the leveling , while effectively eliminating coupling and interference during the leveling process. This method avoids the disadvantages that the displacement and speed of each leg are different during multi-point adjustment, thereby restricting each other, and the specific control algorithm is difficult to implement. At the same time, it does not need to find the highest point, which reduces the system running time and programming workload.

The work flow of the control system is as follows: firstly perform four virtual leg detections, if the detection is not completed, continue the detection, if the detection is completed, set the Z-axis height, if it reaches the first position, continue to perform X-axis calibration, if not continue to perform Z-axis Axis setting, if the X-axis calibration meets the accuracy, continue to calibrate the Y-axis, if the X-axis is not calibrated, continue to perform the X-axis calibration, if the Y-axis calibration meets the accuracy, the work is completed, and the Z-axis resets.

Between the panel and the legs, there is also an adjustment device for the panel as a whole to the left and right. The left and right adjustment device includes a first slider and a guide rail on which the slider moves. The first slider is arranged on the panel. On the opposite side of the length direction of the bottom surface, the first slider moves on two symmetrically arranged first slider guide rails, and the first slider guide rails are installed on the first guide rail fixing frame, fixed on the first guide rail Two ends of the lower surface of the frame are provided with two slider fixing brackets perpendicular to the first guide rail fixing bracket, and a first sliding screw fixing seat is arranged at the middle position of the upper surface of the slider fixing bracket on one side. The first sliding screw rod is arranged in the sliding screw fixing seat, and the first screw pair in the first sliding screw rod is arranged on the bottom surface of the panel.

The suspended equipment leveling device with this structure can support the outriggers on the four ends of the lower surface of the slider fixing frame. In addition to level adjustment, the panel can also be adjusted from left to right.

The hanging equipment leveling device also includes a front and rear adjustment device, the front and rear adjustment device is provided with more than two second sliders on the lower surface of the slider fixing frame of the left and right adjustment device, and the second slider Move on the second slider guide rail, the second slider guide rail is installed on the second guide rail fixing frame, and the second guide rail fixing frame is installed on the two sliding screw seat fixing plates perpendicular to it. The lower surface of the slider fixing frame is provided with a second screw pair, the second sliding screw fixing seat is arranged at the middle position on the sliding screw seat fixing plate, and the second sliding screw is arranged in the second sliding screw fixing seat .
