[0033] The outer surface front side and the outer surface rear side of the suitcase 1 are each provided with one adjusting shoulder strap 206.

[0034] The inside of the suitcase 1 is provided with a movable power supply.

[0035] The working steps of the embodiment are as follows:

[0036] The following directions are based on the view angle of the drawing, wherein the direction of the adjusting shoulder strap 206 is the front direction;

[0037] The following rotation directions are from front to back, from top to bottom and from right to left, and the portable elevator maintenance device is referred to as the device.

[0038] When the staff come to the elevator machine room to clean the elevator steel wire rope, place the device on the ground, add enough cleaning fluid to the two liquid storage boxes 202, and then untie and pull out the two sides of the adjustable shoulder straps 206 of the suitcase 1. The staff squats to the left of the suitcase 1, and then puts on the two adjustable shoulder straps 206 on the shoulders respectively. Then open the lid of the suitcase 1 and hold the device with both hands. At this time, the lid of the suitcase 1 is vertical, and the main body of the suitcase 1 and its components remain horizontal. Then move the device to the side of the traction device. In this way, when working, the device is held in front of the body, and the weight of the device is transferred to the staff's body through the two adjustable shoulder straps 206 on the staff's shoulders, reducing the workload of the staff's arms. When not working, the device is carried on the back through the two adjustable shoulder straps 206, which is convenient for the staff to carry.

[0039] During the process of moving the device to the traction device, the staff moves by grabbing the pull ring 9001 of the two pull rods 9, so that the two mounting blocks 5 rotate around the circular rod 4 with the circular shaft 6, the wool roller 7, the electric push rod 8, the pull rod 9 and the detachable assembly, so that the two mounting blocks 5 that fit are separated and form an acute angle in the suitcase 1. Then move the two wool rollers 7 of the device to the two sides of the steel wire rope of the traction device, and then loosen the two pull rings 9001. Under the action of the torsion spring between the two mounting blocks 5, the two mounting blocks 5 will force the connected components to reset, so that the two mounting blocks 5 merge, and the two wool rollers 7 clamp the linearly arranged steel wire rope to completely wrap the steel wire rope.

[0040] At the same time, the staff opens the switch valve on the two liquid discharge nozzles 203, so that the cleaning fluid in the liquid storage box 202 is discharged from the several liquid discharge holes 20301 of the liquid discharge nozzle 203, flows to the two wool rollers 7, and then controls the traction device to work and drive the steel wire rope to move back and forth. The steel wire rope will drive the two wool rollers 7 to rotate, and at the same time, with the continuous rotation of the two wool rollers 7, the cleaning fluid will continuously discharge to wet the two wool rollers 7 and continuously provide cleaning fluid. The wool roller 7 with cleaning fluid cleans the steel wire rope. During the cleaning process, the extension and retraction of the two electric push rods 8 are controlled to move back and forth, and the sliding block 101, the rubber block 102 and the wool roller 7 move back and forth, so that the sliding block 101 and the wool roller 7 move back and forth on the sliding groove 5001 and the circular shaft 6 respectively. The wool roller 7 moves back and forth to clean the steel wire rope, which can avoid the problem that the wool roller 7 continuously cleans the steel wire rope at the same position, resulting in that the steel wire rope cannot be cleaned completely.

[0041] When the steel wire rope of the traction device is cleaned, the control traction device stops running, the staff closes the switch valve on the two liquid discharge nozzles 203, stops discharging cleaning liquid, moves the pull ring 9001 of the two pull rods 9 again, drives the connected parts to rotate, and lets the two wool rollers 7 no longer wrap the steel wire rope. After moving away from the traction device, release the pull ring 9001, and then place the device on the ground.

[0042] When the steel wire rope is cleaned and needs to be oiled, the staff needs to replace the used wool roller 7. Taking the left wool roller 7 as an example, the replacement steps are as follows: on one side, press the pin column two 105 on the mounting block 5 into the countersunk hole 5003, forcing the spring two 106 to compress, at the same time, when the pin column two 105 moves, it will push the pin column one 104 back into the cylindrical groove 6001, forcing the spring one 103 to compress, the pin column one 104 is separated from the cylindrical shaft 6 and the wool roller 7, on the other side, hold the pull ring 9001 and drive the mounting block 5, the electric push rod 8, the pull rod 9, the sliding block 101 and the rubber block 102 to rotate, while the cylindrical shaft 6 and the wool roller 7 remain unchanged. Then the staff removes the used wool roller 7 from the cylindrical shaft 6 and installs the new wool roller 7 on the cylindrical shaft 6, then releases the pull ring 9001, and the mounting block 5 drives the connected parts to reset under the action of the torsional spring. At this time, the staff manually presses the pin column one 104 back into the cylindrical groove 6001, so that the pin column one 104 smoothly enters the inside of the mounting block 5. When the pin column one 104 is opposite to the countersunk hole 5003, the pin column one 104 is inserted into the countersunk hole 5003 under the automatic reset of the spring one 103, and the cylindrical shaft 6 is fixed again. At this time, the new wool roller 7 is just clamped between the two rubber blocks 102, and the new wool roller 7 is limited by the two rubber blocks 102. The other used wool roller 7 is replaced in the same way. This not only saves time but also improves the efficiency of elevator maintenance.

[0043] When the staff replaces the two wool rollers 7, remove the two liquid storage boxes 202 from the corresponding mounting frames 201, put them into the two liquid storage boxes 202 containing lubricating oil (special oil for elevator steel wire ropes), and then refer to the way of cleaning the steel wire rope with the wool roller 7 to evenly coat the lubricating oil on the outer surface of the steel wire rope, ensuring the coating effect of the steel wire rope and avoiding uneven and missing of the lubricating oil, which reduces the service life of the steel wire rope. This makes the device not only clean the steel wire rope, but also coat the lubricating oil on the steel wire rope.

[0044] It should be noted that when the staff clean and coat the elevator wire rope with lubricating oil, the light supplement lamp 205 on the suitcase 1 cover can be controlled to turn on, and the continuously moving wire rope is illuminated by the light supplement lamp 205, so that the staff can observe the cleaning and oiling of the wire rope, and also can observe whether the wire rope is worn out, and when the staff climbs on the top of the elevator car to check, the top of the car is relatively dark, the staff can open the cover of the suitcase 1 and control the light supplement lamp 205 in the suitcase 1 to turn on for illumination, which is convenient for the staff to check the elevator.

[0045] It should be noted that if a small amount of oil stains are attached to the wool roller 7 or the inside of the suitcase 1, the oil stains are easy to stick to the clothes on the back of the staff when the staff carry the device on their back, which pollutes the clothes of the staff, and before the staff carry the device, the two sealing plates 204 are manually combined, and the two sealing plates 204 are tightly attached by the magnets on the sealing plates 204, so that the oil stains in the wool roller 7 or the inside of the suitcase 1 are prevented from sticking to the clothes of the staff.

[0046] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
