Background

Portal cranes are also known as jib cranes, in which a rotatable hoisting device (referred to as rotating part) is mounted on a portal frame. The 4 legs of the portal frame form 4 'door openings' for railway vehicles and other vehicles to pass through. The gantry crane is usually operated along a crane rail on the ground or a building to perform a lifting, loading and unloading operation. At present, the portal crane is mainly used for port machinery operation. The bridge is supported on the ground rail or foundation through the supporting legs at two sides, and has the characteristics of running along the ground rail and passing through railway vehicles or other ground vehicles below. The gantry crane is also gradually popularized and applied to docks, hydropower station construction sites and the like with operation conditions close to ports. The control part of the portal crane is an important part of the portal crane and is directly related to safe production and working efficiency. But because portal jib crane's special operating mode environment, there is not a set of comparatively advanced control system yet in the prior art, satisfies current portal jib crane demand accurate day by day.

If the gantry crane grab bucket is replaced by a lifting hook, other sundries are lifted, when the crane works, a control center operator can set coordinates such as a starting point, a terminal point and the height of the lifting hook of the fallen sundries, the gantry crane is started to the lifting object starting point, the lifting hook is placed to the set height, the crane waits for the operation of a field crane by using a field remote controller JT-KP, the lifting hook is placed to a proper position to be hooked, then the crane enters an automatic mode after being lifted to the set height, the gantry crane automatically rotates, the lifted object is lifted to the terminal point position automatically, then the lifting hook is placed to the set height, the crane waits for the terminal crane to place the lifted object on the ground by using the remote controller JT-KP, and the process is repeated;

When the device works, firstly, sampling is carried out, the touch screen VMC1100 collects the swing amplitude positions of the grab bucket of the gantry crane under the rotation and amplitude variation working conditions of different weights, different heights, different speeds and different wind speeds, then the data are uploaded to a GIS management platform through a 5G communication module CPEPRO for calculation and simulation respectively, then the simulated program is sent to the touch screen VMC1100 through the 5G communication module CPEPRO, the touch screen VMC1100 is sorted, respectively solidifying the rotation anti-swing program to the left rotation anti-swing module CX-FY400, the right rotation anti-swing module CX-FY400 and the amplitude variation anti-swing module CX-FY400, when in work, under different working conditions, the touch screen VMC1100 commands different anti-swing modules to regulate and control the frequency converter according to control parameters under different weights, different heights, different speeds and different wind speeds, so that the aim of inhibiting the swing amplitude of the grab bucket is fulfilled;

to further illustrate the anti-swing working principle of the door seat machine, the working conditions of the door seat machine are as follows: the coal is grabbed from the cabin and conveyed to a telescopic coal unloading hopper under the crotch of the gate seat machine, then the coal is unloaded to a belt conveyor by the hopper, and the coal is conveyed to a coal yard by the belt conveyor;

therefore, the height from the grab bucket to the coal unloading hopper is relatively fixed every time, and the coal grabbing route is as follows: the grab bucket (fed back by the GPS antenna 1AT300 of the grab bucket mobile base station 1 CX-E708) is lifted vertically from a cabin to pass through a cabin opening (fed back by the GPS antenna 4BT5630 and the GPS antenna 5BT5630 of the portable ship mobile base station) to accelerate lifting (the speed is fed back by an operating handle) + amplitude variation (the angle sensor CX-JD 90) to be higher than the proper position of the coal unloading funnel (the height encoder 1GM58S10K6MA12 WN), the amplitude variation anti-swing module CX-FY400 works to approach the proper position above the coal unloading funnel (the angle sensor CX-JD90 feeds back) and the PLC S7-1500 commands the grab bucket switch ATV930 to open the grab bucket unloading coal (the weight sensor 1JZ-1 and the weight sensor 2 JZ-1), when the impact speed of the grab bucket reaches the center point of the coal unloading funnel, after the coal of the grab bucket is unloaded (fed back by the weight sensor 1JZ-1 and the weight sensor 2 JZ-1), the amplitude-variable anti-swing module CX-FY400 finishes working, and when the speed of the grab bucket is zero (fed back by the GPS antenna 1AT300 of the grab bucket mobile base station 1 CX-E708), the PLCS7-1500 immediately shifts gears to order the amplitude-variable frequency converter ATV930 to move in the opposite direction, so that the air anti-swing and air bucket-swinging operation process is completed, and the efficient operation of the grab bucket is realized;

according to the principle, in order to improve the efficiency of grabbing coal by the grab bucket, the height and the size of a coal pile in the cabin collected by a 3D laser scanner CX-JS800 are analyzed by a touch screen VMC1100, and then a PLC (programmable logic controller) S7-1500 is controlled according to the position coordinate of the coal pile, the high and large priority grabbing and transporting of the coal pile is set above the ship edge AT zero speed according to the convention, but in order to grab coal material under the ship edge, the grab bucket is opened AT a proper position in the ship cabin (fed back by a GPS antenna 1AT300 of a grab bucket moving base station 1 CX-E728) by utilizing the anti-swing stroke sequence of an amplitude anti-swing module CX-FY400 according to the height of the coal pile (fed back by the GPS antenna 1AT300 of the grab bucket moving base station 1 CX-E728) according to the height of the 3D laser scanner CX-JS800 and the horizontal position of the opened grab bucket, and the arm support is accurately thrown to the coal material under the ship edge by the speed of the grab bucket, meanwhile, the ship edge and the ship body cannot be impacted, so that the functions of aerial anti-swing and bucket-throwing and coal-grabbing operation are realized.

And on the basis of two-dimensional scanning, a holder is added to perform orthogonal rotation, so that three-dimensional space scanning can be formed. The three-dimensional coordinate information and the reflectivity information of a large number of dense points on the surface of the measured ship body are recorded through the scanner controller CX-X8000, the three-dimensional data of various ship body scenes are completely collected into the controller CX-X8000 and processed through point cloud processing software, and then various drawing data such as a three-dimensional model of the measured ship body and lines, surfaces and bodies of a material pile in a cabin are quickly reconstructed.

Because the laser can penetrate through the glass, the 3D laser material scanner CX-JS800 can be well protected and can be used for severe environment measurement (high temperature, high pressure, high humidity and high dust). Because the laser emission angle is very small (< 0.2 degrees), the 3D laser material scanner CX-JS800 can measure the material level in a narrow space, three-dimensional measurement can be carried out on irregular material level, then the detected information is sent to the image controller CX-X8000, the image controller CX-X8000 is provided with point cloud processing software, three-dimensional images of the material level are formed through the processing of the point cloud processing software, the lowest material level, the highest material level, the average material level, the cabin distance, the cabin height, the cabin width and the like of the cabin material level are obtained, then the three-dimensional images are sent to the PLC controller S7-1500 through the switch HI-08 in a protocol mode, the PLC controller S7-1500 is sent to the touch screen VMC1100, and the position of a cart or the posture of an arm support is adjusted by the touch screen VMC1100 according to the coal catching rule, so that the grab bucket can accurately fall to the highest material level of the cabin; the touch screen VMC1100 controls the PLC S7-1500 to work, and simultaneously sends the work to the GIS management platform and the client T8520 through the 5G communication module CPEPRO for the client T8520 to monitor and use.
