In one embodiment, test line 100 is a steel wire rope.
The steel wire rope is a spiral steel wire bundle formed by twisting steel wires with mechanical property and geometric dimension meeting requirements together according to a certain rule, and consists of the steel wires, a rope core and lubricating grease. The steel wire rope is a spiral rope which is formed by twisting a plurality of layers of steel wires into strands, and then twisting a certain number of strands by taking a rope core as a center. In a material handling machine for lifting, pulling, tensioning and carrying. The steel wire rope has high strength, light dead weight, stable work, difficult sudden whole breakage and reliable work. The use of the wire rope as the detection rope 100 can extend the service life of the detection device and delay the breakage due to the cumulative multiple times of pressure generated when the drive shaft 421 of the positioning vehicle drive device 420 falls off.
In one embodiment, the test cord 100 may also be a nylon cord.
In one embodiment, more than two support rings are further included and are disposed on the positioning cart body 410 for supporting the detection rope 100.
Since the detection string 100 has a certain weight, a portion away from the first fixing portion, the second fixing portion, and the pulling portion may be dropped by the weight, so that the portions of the detection string 100 are difficult to keep a relative distance with the driving gears 422, and if the weight of the detection string 100 is too heavy, the pull switch 200 may be erroneously operated by a tensile force generated by the weight of the detection string 100.
