Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel rope corrosion resistance detection, in particular to a steel rope corrosion resistance detection device convenient to operate. BACKGROUND

[0002] In actual use (such as crane, elevator, ship and other scenes), the steel rope will inevitably undergo repeated bending, stretching, twisting and other deformations. Such deformations can easily cause micro-cracks, peeling or adhesion loss of the surface protective layer (such as zinc plating layer, plastic coating layer) of the steel rope. The damage of the protective layer is the "breakthrough" of corrosion. The salt and moisture in the environment will enter the steel wire matrix through the damaged part, causing local corrosion (pitting, crevice corrosion, etc.).

[0003] However, the existing corrosion resistance detection equipment cannot artificially create a protective layer damage similar to actual service when in use, so that the real corrosion risk is underestimated when the salt spray test is performed due to the intact protective layer of the steel rope, resulting in a deviation of the test results from the actual failure path of the rope.

[0021] In summary, when using the convenient steel rope rigging corrosion resistance detection equipment: First, connect the rigging at both ends of the steel rope to the opposite ends of the key shaft one 204 and the transmission shaft 310 through the lug 311, respectively, and close the transparent chamber door 8 of the front opening of the salt spray test chamber 1, start the stretching electric cylinder 206, and pull the key shaft one 204 connected to the stretching end back into the hole key groove in the driven gear 203, so that the steel rope is stretched and then continuously stressed to artificially create a tensile deformation similar to actual service, then start the motor 207 and drive the driving gear 208 at the front end of the driving shaft 306 to rotate, the driving gear 208 rotates the key shaft one 204 through the meshing with the driven gear 203, and then the key shaft one 204 rotates through the rotary connecting piece 205 at the stretching end of the stretching electric cylinder 206, in addition, the motor 207 also drives the gear set one 307 at the end of the driving shaft 306 to rotate, the gear set one 307 rotates the gear set two 309 at the root of the transmission shaft 310 through the key shaft two 308, and then the key shaft one 204 and the transmission shaft 310 rotate in opposite directions, and then artificially create a torsional deformation similar to actual service by twisting the steel rope at both ends in opposite directions; Secondly, the driving shaft 306 also drives the rear-end coaxial cam 305 to rotate, and then converts the rotary motion of the cam 305 into the reciprocating swing of the floating frame 303 on the roller 304 through the contact between the profile of the cam 305 and the roller 304. During this process, the floating frame 303 swings reciprocally on the fixed frame 301 through the spring rod 302 and guarantees the constant close contact between the roller 304 and the profile of the cam 305 through the spring elastic force, thereby guaranteeing the stability of the transmission of the cam 305.

The present application only needs to set one motor 207, so that the driving shaft 306 drives the front-end driving gear 208 and the end gear set one 307 to rotate, thereby realizing the rotation of the key shaft 204 and the transmission shaft 310 in opposite directions to artificially create a torque deformation of the steel rope, and also driving the reciprocating swing of the floating frame 303 through the cam 305, thereby simulating the reciprocating bending application scene of the steel rope. Through mechanical linkage, the protective layer on the surface of the steel rope is subjected to damage close to the actual service, thereby guaranteeing that the subsequent salt spray test result is close to the actual failure path of the rigging. Finally, the water pump 12 is started to pump out the salt water in the salt water tank 11 and spray it out through the atomizing nozzle of the top-end sprayer 13 inside the salt spray test box 1, so as to create a NaCl solution mist environment in the salt spray test box 1, and start the heating coil 9 at the bottom end inside the salt spray test box 1 to heat the environment. Through high-concentration salt mist, the marine, coastal or high-salt industrial environment is simulated to accelerate the corrosion process. By observing the time when the first red rust spot appears, the corrosion resistance of different riggings can be quantitatively compared. The longer the red rust period is, the stronger the ability of the steel rope rigging to resist salt spray corrosion after deformation damage is. This method combines deformation pretreatment with accelerated corrosion test, accurately fits the actual service characteristics of the steel rope rigging, and improves the reliability of the corrosion test result.
