[0036] A method for evaluating the service life of an elevator wire rope comprises the following steps:

[0037] Step 1: The threaded rod 202 is driven to rotate by the motor 201, thereby driving the sliding block 203 to move, and then driving the pulling rod 204 to move. The combination of the pulling rod 204 and the fixed rod 205 can simulate the pulling force of the elevator on the wire rope;

[0038] Step 2: The fan blades 308 can be driven to rotate by starting the water pump 301, thereby generating wind force, simulating the use of the steel wire rope in a ventilated environment, using the electric heating wire 309 to generate heat to simulate the use of the steel wire rope in a hot environment, and the liquid sprayed by the water spray pipe 313 can simulate the use of the steel wire rope in a humid environment;

[0039] Step three: The protective cover 401 is covered on the pulling rod 204 and the fixed rod 205 to prevent the steel rope from breaking and causing harm to the staff, and the protective cover 401 is prevented from accidentally sliding by utilizing the engagement of the engagement head 1 411 and the engagement head 2 413 and by utilizing the combining sleeve 408 which is mounted on the joint of the engagement head 1 411 and the engagement head 2 413.

[0040] Working principle: When evaluating the service life of the elevator wire rope, first test the tension on the wire rope when it is used in the elevator, wrap the two ends of the wire rope around the top of the fixed rod 205 and the pulling rod 204 respectively, start the motor 201, and the output end of the motor 201 can drive the threaded rod 202 to rotate after it rotates. After the threaded rod 202 rotates, since the sliding block 203 is restricted by the sliding groove 206, when the threaded rod 202 rotates, it can drive the sliding block 203 to move, and then drive the pulling rod 204 to move away from the fixed rod 205, and then stretch the wire rope to simulate the tension on the wire rope from the elevator;

[0041] Start the water pump 301. The input end of the water pump 301 draws out the liquid in the water storage tank 316 through the water inlet pipe 303, and enters the inside of the impeller 305 through the water outlet pipe 302. At this time, the water flow can be used to drive the impeller 305 to rotate, and then the fan blades 308 can be driven to rotate. After the fan blades 308 rotate, wind can be generated, and then the wind can be poured into the inside of the protection mechanism 4, so as to simulate the use of the wire rope in a ventilated environment. When the fan blades 308 rotate, the electric heating wire 309 can be started, and the electric heating wire 309 generates heat. The hot air can enter the interior of the protection mechanism 4, simulating the use of the steel wire rope in a high temperature environment. When the water in the installation box 304 passes through the connecting pipe 310, the valve 1 311 is opened and the valve 2 314 is closed. The liquid in the connecting pipe 310 will enter the water spray pipe 313 through the hose 312 and be sprayed out, thereby simulating the use of the steel wire rope in a humid environment. If only a ventilated or hot environment is simulated, the valve 1 311 is closed and the valve 2 314 is opened. At this time, the liquid in the connecting pipe 310 will be discharged into the water storage tank 316 through the pumping pipe 315.

[0042] When testing the wire rope, the protective cover 401 is slid toward the baffle plate 5 and makes the protective cover 401 contact the side of the baffle plate 5 close to the protective cover 401. At this time, the fixed column 404 will also slide with the protective cover 401. When the locking head 1 411 is about to contact the locking head 2 413, the wrench 406 is turned toward the protective cover 401, which can then drive the movable column 409 to move away from the installation column 412, and then drive the coupling sleeve 408 to slide away from the installation column 412. At this time, the locking head 1 411 can be exposed, and the protective cover 401 can be removed. 01 continues to slide in the direction of the baffle 5, so that the locking head 1 411 and the locking head 2 413 are locked. After the locking, the wrench 406 is loosened, and under the action of the reset spring 410, the coupling sleeve 408 can be driven to move towards the mounting column 412, and then the coupling sleeve 408 can be mounted on the locking position of the locking head 1 411 and the locking head 2 413. At this time, the protective cover 401 cannot be pulled. After the detection and evaluation is completed, the wrench 406 is pulled again to make the coupling sleeve 408 leave the joint of the locking head 1 411 and the locking head 2 413, so that the protective cover 401 can be pulled away from the baffle 5.
