Abstract
The invention discloses a crane positioning device which is characterized in that a coder is installed on a main shaft of a driving motor of a cart or a trolley, a calibrating photoelectric switch is installed on a cart orbit or a trolley orbit, the coder and the photoelectric switch can be connected with a programmable controller PLC, and the programmable controller PLC is connected with a vehicle computer through a communication interface. The crane positioning device is characterized in that the coder and the photoelectric switch are combined to locate so as to ensure the precise locating. The position information of the crane can be displayed through the vehicle computer and facilitates the operation of a driver.
Description
Technical field:
The present invention relates to the registration device in a kind of crane carrying workpiece process.
Background technology:
At present, the locate mode of existing crane has following several:
1. utilize travel switch location, on the orbit of the cart of crane, dolly, travel switch is installed and is located, but shortcoming such as travel switch exists that speed of response is low, low precision and life-span are short.
2. utilize laser range sensor to position, it penetrates a branch of very thin laser to crane, receives crane laser light reflected bundle again, measures laser beam from being transmitted into the time of reception, calculates the distance and then the location of crane.Though laser range sensor can improve accuracy of positioning to a certain extent, it is affected by environment greatly, cost is high, and the vibrations that crane is in operation can cause than mistake.
Summary of the invention:
The present invention is directed to the above-mentioned deficiency of prior art, provide a kind of life-span long, precision is high, speed of response is fast and jamproof crane positioning device.
Technical solution of the present invention is: a kind of crane positioning device, on the drive motor main shaft of cart or dolly, coder is installed, and on cart or trolley travelling track, the check and correction photoelectric switch is installed; Coder and photoelectric switch are connected with Programmable Logic Controller PLC, and Programmable Logic Controller PLC is connected with vehicle-mounted computer by communication interface.This device utilizes the move distance of coder mensuration cart or dolly and then positions.Skid in orbit for fear of crane wheel in the emergency braking process, coder is not counted the error that causes, and also is equipped with a plurality of photoelectric switchs that are used to proofread initial position in orbit.
Because general lifting operation is not high to the dolly positioning accuracy request, dolly can only position by the photoelectric switch that is installed on its orbit, and the spacing between the photoelectric switch is less than the width of dolly.Per like this two photoelectric switchs are determined a position location, prevent deviations.
Described coder is 12 photoelectric encoders, and its model is EPC-K38-5-24.
The model of described photoelectric switch is KH20-A-A.
The model of described Programmable Logic Controller PLC is Siemens S7200CPU222CN.
Outstanding feature of the present invention is to utilize coder and photoelectric switch integrated positioning, to guarantee that the location accurately.The location information of crane can show by vehicle-mounted computer, is convenient to the driver and controls.Utilize coder location, control cabin is known its particular location, and coder can corresponding a plurality of control stations, make things convenient for on-site installation and maintenance, the cost that reduces the wastage, and the coder long service life, cost performance is higher.Photoelectric switch has then that volume is little, the life-span is long, precision is high, speed of response is fast, detect advantages such as distance and antijamming capability are strong.
Description of drawings:
Fig. 1 is the control principle block diagram of the embodiment of the invention 1.
Fig. 2 is the control principle block diagram of the embodiment of the invention 2.
The specific embodiment:
The present invention will be further described below in conjunction with accompanying drawing:
Embodiment 1:
As shown in Figure 1, a kind of crane positioning device is equipped with the cart coder on the drive motor main shaft of cart, and a plurality of cart check and correction photoelectric switchs are installed on the cart orbit; The dolly photoelectric switch is installed on the trolley travelling track, and the spacing between the dolly photoelectric switch is less than the width of dolly, and per like this two photoelectric switchs are determined a position location, prevent deviations; Coder and above-mentioned all photoelectric switchs are connected with Programmable Logic Controller PLC, and Programmable Logic Controller PLC is connected with vehicle-mounted computer by serial interface.Wherein coder is that 12 photoelectric encoder models are EPC-K38-5-24, and the model of above-mentioned photoelectric switch is KH20-A-A, and the model of Programmable Logic Controller PLC is Siemens S7200CPU222CN.
Embodiment 2:
As shown in Figure 2, a kind of crane positioning device, on the drive motor main shaft of cart and dolly, be separately installed with cart coder and dolly coder, on cart and trolley travelling track, be separately installed with a plurality of cart check and correction photoelectric switchs and dolly check and correction photoelectric switch; Above-mentioned all coders and photoelectric switch are connected with Programmable Logic Controller PLC, and Programmable Logic Controller PLC is connected with vehicle-mounted computer by serial interface.Wherein coder is that 12 photoelectric encoder models are EPC-K38-5-24, and the model of above-mentioned photoelectric switch is KH20-A-A, and the model of Programmable Logic Controller PLC is Siemens S7200CPU222CN.Present embodiment utilizes coder to measure the miles of relative movement of cart and dolly, and proofreads the initial position of cart or dolly by photoelectric switch, avoids crane wheel in the emergency braking process to skid in orbit, and coder is not counted the error that causes.At first move when crane starts at every turn and trigger the check and correction photoelectric switch, determine initial position, determine the position location through encoder to count again.
