Technical Field
The invention belongs to the technical field of pulley steel wire rope maintenance, and particularly relates to a wear early warning device and method for a grab pulley steel wire rope.
Background
The steel wire rope is in a long-time continuous working state, the working environment is bad, and in order to ensure safe production, the broken wire, broken wire of the cage strand, burrs, abrasion, corrosion and diameter change of the steel wire rope must be checked frequently. The abrasion of the steel wire rope is hidden and difficult to judge visually, so that at present, only human eyes can inspect the steel wire rope, or the abrasion of the steel wire rope can be judged by inspecting the indentation of the pulley, or an ultrasonic flaw detector is used for detecting the damage of the steel wire rope. Because the steel wire rope is generally longer, the manual detection efficiency is low, and the effect is poor; the steel wire rope clings to the pulley, and the observation of the indentation of the pulley is inconvenient; the frequency of ultrasonic flaw detection is also limited, and the steel wire rope running cannot be detected. Therefore, some hidden dangers of the steel wire rope in operation are difficult to find and determine, and as a result, the steel wire rope with broken wires or excessive abrasion is still used, so that serious potential safety hazards are left or the steel wire rope is replaced without being replaced, and the operation cost and the fund cost are greatly wasted.

According to the scheme, the middle position of the early warning rod is horizontally provided with a reinforcing steel bar.
According to the scheme, the early warning rod is attached to the top end of the side wall of the pulley slideway or a certain distance is reserved between the early warning rod and the top end of the side wall of the pulley slideway.
According to the scheme, the distance is not more than half of the diameter of the steel wire rope.
The wear early warning method for the grab bucket pulley steel wire rope is characterized by comprising the following steps of:
The early warning frame is installed corresponding to the pulley, when the grab bucket is in closed movement, the abrasion condition of early warning rods on two sides of a pulley slideway is observed, the stress condition of the steel wire rope is judged, and according to the analysis reason of abrasion mark positions, whether the grab bucket body is deformed, the pulley shaft is deformed and the pulley shaft is broken or not is overhauled, meanwhile, whether a knob is arranged on the steel wire rope pair or not is checked, the length of the steel wire rope is required to be adjusted, the discovered faults are overhauled or replaced in time, and the steel wire rope is guaranteed to run in the pulley slideway, so that the loss of the steel wire rope is reduced.
The beneficial effects of the invention are as follows: according to the wear early warning device and method for the grab bucket pulley steel wire rope, maintenance staff can easily see whether steel wire rope wear marks exist on the wear early warning device through daily work, whether a pulley block is in shaft shifting or deformation overhauling according to the wear mark position analysis reasons, whether the grab bucket body is deformed or whether the length of the steel wire rope needs to be adjusted or not is checked, whether the steel wire rope is twisted or not is checked, so that the normal operation of the grab bucket is guaranteed, the steel wire ropes on two sides are stressed uniformly as much as possible, the wear of the steel wire ropes is reduced, and the occurrence of safety accidents is avoided.

Fig. 2 is a side view of one embodiment of the present invention.
Detailed Description
For a better understanding of the present invention, reference is made to the following description of the invention taken in conjunction with the accompanying drawings and examples.
As shown in fig. 1 and 2, the wear early warning device for the grab bucket pulley steel wire rope comprises an early warning frame, wherein the early warning frame comprises an early warning rod 1, an upper base 2 and a lower base 3, the upper base and the lower base are arranged in an up-down symmetrical mode through brackets on two sides of a pulley 4, the upper base and the lower base respectively correspond to the top and the bottom of the pulley, the early warning rod is of a semicircular arc structure, two groups of early warning rods are arranged along the top ends of two side walls of a pulley rope groove, and two ends of the early warning rod are fixedly connected with the upper base and the lower base respectively.
The reinforcing steel bar 5 is horizontally arranged at the middle position of the early warning rod, the strength of the early warning rod is enhanced through the reinforcing steel bar, and abrasion marks cannot be monitored in time after the early warning rod is prevented from being deformed.
The upper base and the lower base are made of angle steel, and the early warning rod is made of screw steel. The materials are common materials, the cost is low, and the rigidity of the deformed steel bar meets the application requirements.
The early warning rod is attached to the top end of the side wall of the pulley slideway or a certain interval is reserved between the early warning rod and the top end of the side wall of the pulley slideway, and the size of the interval is not more than half of the diameter of the steel wire rope, so that the steel wire rope is prevented from falling off the groove.
The grab bucket lifting rope depends on the pulley groove and the baffle plate at the bottom of the pulley block to determine the running track so as to realize the normal opening and closing of the grab bucket. The two steel wires should be synchronous during the closing movement of the grab bucket, and keep even stress, but in the actual overhaul process, the stress of the two steel wires cannot be the same. The steel wire rope can cause the problems of grab bucket body deformation, pulley shaft shifting and the like of the grab bucket due to different stresses. These problems in turn aggravate the different atress of two wire ropes, and these changes make wire rope take place horizontal displacement, make wire rope break away from pulley groove bottom and rely on cell wall department to produce friction with pulley rope groove wall, not only probably produce wire rope and take off the groove, can also aggravate wire rope's wearing and tearing. However, the grab bucket body of the grab bucket deforms, the pulley shaft deforms and the pulley shaft is fleed, and the phenomenon that the pulley shaft is fleed is difficult to find in time due to the small variation, and through the device, when the problems occur, the problems can be found by observing the grinding marks on the threaded steel, and the inspection personnel can check the problems in time, so that the two steel wire ropes are uniformly stressed and the wear is reduced. Meanwhile, the steel wire rope can be prevented from being out of the groove.
The method for carrying out the early warning on the loss of the steel wire rope comprises the following steps:
The early warning frame is installed corresponding to the pulley, when the grab bucket is in closed movement, the abrasion condition of early warning rods on two sides of a pulley slideway is observed, the stress condition of the steel wire rope is judged, and according to the analysis reason of abrasion mark positions, whether the grab bucket body is deformed, the pulley shaft is deformed and the pulley shaft is broken or not is overhauled, meanwhile, whether a knob is arranged on the steel wire rope pair or not is checked, the length of the steel wire rope is required to be adjusted, the discovered faults are overhauled or replaced in time, and the steel wire rope is guaranteed to run in the pulley slideway, so that the loss of the steel wire rope is reduced.
