The device comprises a plate hook 1, a left laser displacement sensor 2, a winding drum band-type brake device 3, an analysis control unit 4, an alarm device, a winding drum 7, an encoder 8, a right laser displacement sensor 9 and two steel wires 10, wherein the two steel wires 10 are wound on the winding drum 7, the tail ends of the two steel wires 10 are respectively connected with the left end and the right end of the plate hook 1, and the left laser displacement sensor 2 and the right laser displacement sensor 9 are respectively arranged at the positions outside the two steel wires 10 below the winding drum 7; the winding drum band-type brake device 3 and the encoder 8 are connected with the winding drum 7; the input end of the analysis control unit 4 is respectively connected with the left laser displacement sensor 2, the encoder 8 and the right laser displacement sensor 9, and the output end of the analysis control unit 4 is connected with the winding drum brake device 3 and the alarm device.
The analysis control unit 4 comprises a data acquisition module 41, a data analysis module 42, a safety interlocking module 43, a driving output module 44 and an alarm output module 45, wherein the input end of the data acquisition module 41 is connected with the left laser displacement sensor 2, the encoder 8 and the right laser displacement sensor 9; the data acquisition module 41, the data analysis module 42 and the safety interlocking module 43 are sequentially connected, and the output end of the safety interlocking module 43 is respectively connected with the driving output module 44 and the alarm output module 45; the driving output module 44 is connected with the winding drum brake device 3, and the alarm output module 45 is connected with the alarm device.
The alarm device comprises a tablet personal computer 5 and an alarm horn 6.
The left laser displacement sensor 2 and the right laser displacement sensor 9 are matched with the positions of the steel wire ropes 10.
The winding drum band-type brake device 3 and the encoder 8 are respectively connected to two sides of the winding drum 7.
The analysis control unit comprises a data acquisition module, a data analysis module, a safety interlocking module and other operation programs.
The data acquisition module is responsible for receiving real-time signals such as the working states of the left laser displacement sensor, the right laser displacement sensor, the encoder and the winding drum;
the data analysis module is used for comparing and analyzing the data acquired by the data acquisition module with a standard reference value;
the safety interlocking module gives an alarm or an interlocking parking instruction to the analysis result of the data analysis module.
The left laser displacement sensor and the right laser displacement sensor measure the inner and outer moving distance change values of the steel wire ropes at two sides in real time, and the encoder records the rotation angle, the direction and the revolution of the winding drum in real time.
In practical application, the left laser displacement sensor and the right laser displacement sensor are respectively arranged at the proper positions of the outer platforms of the two steel wire ropes below the crown block winding drum and are used for measuring the real-time distance change condition of inward or outward movement of the steel wire ropes at the left side and the right side. When the winding drum and the steel wire rope normally work, firstly, the crown block is hooked to the upper limit, at the moment, the rotation angle and the number of turns of the winding drum are set to 0, the rotation angle of the winding drum gradually increases along with the decrease of the plate hook, the angle value becomes 0 again after the rotation angle of the winding drum is larger than 360 degrees, the rotation number of turns becomes 1 again, the next period is restarted, the angle value becomes 0 again after the winding drum rotates 360 degrees again, the rotation number of turns becomes 2, and so on, if the rotation angle and the number of turns of the winding drum are increased by the plate hook, the rotation angle and the number of turns of the winding drum are correspondingly reduced. The calculated and corrected distance value that the steel wire rope should move inwards or outwards when the rotation angle of the winding drum is alpha and the number of turns is N is taken as a standard reference value during normal operation of the equipment. Assuming that the distance between the central lines of two adjacent steel wire ropes on the winding drum is L, the distance between the two adjacent steel wire ropes is changed by the value L/360 when the winding drum rotates for N circles and the angle of the winding drum is alpha, the moving distance of the steel wire ropes is as follows: α/360+n l=l (α/360+n), and the result is corrected according to the actual situation in the field.
Wherein: alpha: (alpha is more than 0 and less than or equal to 360) is the rotation angle of the winding drum,
l: center line distance between two adjacent steel wire ropes on winding drum
N: (N is more than or equal to 0) rotation number
After the detection device is formally put into operation, the data acquisition module acquires the reel rotation angle, the rotation number and the rotation direction recorded by the encoder and the real-time change value of the distance between the steel wire ropes recorded by the left laser displacement sensor and the right laser displacement sensor. When the crane hoist weight rises or falls, the actual distance value of the steel wire ropes on the left side and the right side is compared with the standard reference value in real time through the data analysis module when the reel rotates to any angle and turns, after the difference value exceeds a certain range, the alarm output module in the safety interlocking module carries out text and voice alarm on alarm information through the tablet personal computer and the alarm horn, after the difference value exceeds an upper limit value, the drive output module in the safety interlocking module sends out an band-type brake instruction to the reel band-type brake device when sending an alarm, the crane is forbidden to continue to use, and the fault elimination and alarm reset back can continue to work.
