Description
Technical Field
The utility model belongs to power station headstock gear field especially relates to a power station headstock gear position measurement system.
Background
For a hoisting hoist of a hydropower station, the main functions are to hoist and transport the maintenance gate. A typical device in a hoisting hoist is a mobile hoist. With the development of automation technology and sensor technology, the operation process of the mobile hoist has been automated and digitized to a certain extent. The main applied automation technology comprises a video monitoring technology, height measurement based on a drum end encoder, large and small vehicle position measurement based on a wheel encoder, load measurement based on a pressure sensor and the like. The measuring signals can be connected to a crane control system to participate in automatic control. The hoist position measurement, especially the continuous position measurement, mainly depends on an encoder connected to the wheel to continuously record the rotating angle of the wheel, and the rotating angle is converted into the hoist position information. In other crane industries, two-dimensional code technology is also adopted to realize current position detection.
For a movable hoist, full-automatic gate opening and closing and hoisting are not achieved at present, and the matching of the hoist and the gate on a dam still needs to be observed by people for operation. Absolute encoders mounted on wheels do not reliably and accurately meet the position detection requirements of mobile hoists. Firstly, because of the error of absolute value encoder itself, can constantly accumulate in the headstock gear operation process. Secondly, the wheel can skid or the diameter error of the vehicle can cause the inaccuracy when the position of the hoist is converted because of the running of the hoist. Thirdly, the encoder connected to the wheels only measures the rotation angle of the vehicle to convert the rotation angle into the position of the hoist, and the position of the hoist or the gate of the hoist relative to the gate slot of the dam is finally considered when the gate is hoisted by the movable hoist. From the rotation angle of the wheels to the final position of the sling, a plurality of links are arranged in the middle. Therefore, the continuous position measurement of the hoist can not meet the automatic operation requirement of the hoist by the wheel position.

Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
The utility model provides a power station headstock gear position measurement system, including setting up laser scanner 1 in the 4 lower parts of dolly of headstock gear, 1 connection treater of laser scanner connects memory and communication unit on the treater, and communication unit is used for connecting with the control system of current headstock gear. The processor may be mounted directly to the electrical compartment of the hoist.
Further, the hydropower station starting and stopping equipment position measuring system further comprises a gate slot reflector 33 arranged at the gate slot of the dam face.
In the downward scanning process of the laser scanner 1, three-dimensional coordinate data and reflectivity data of all scanning points at the lower part can be acquired and sent to the processor, the reflectivity range of the door slot reflector 33 is preset in the processor, after the processor acquires the data, the reflectivity data and the reflectivity range of the door slot reflector 33 are simply compared, the scanning points belonging to the door slot reflector 33 are acquired, and then the position of the door slot reflector 33 is acquired according to the three-dimensional data of the scanning points and sent to the processor. The position information can be sent to the processor and then sent to a control system of the hoist through the processor, so that the control system of the hoist can conveniently carry out position correspondence of the gate and the gate slot according to the position information.
