How to replace the counter rope wheel of a high speed elevator? Ask for advice

1.Rebound Look: Make the character you control turn in the air Rebound Tutorial:

Start pressing the arrow keys "Run to the right and then release it immediately" at the same time press the " key and the spacebar ( this is a momentary thing ) The effect you see is that after turning in the air and then the character lands in the opposite direction, you can also try jumping from right to left 2Rope Jumping Look: The moment you climb on the rope, you leave the rope and make the body of the person you control fall face the rope (the rope can also be a ladder These actions are done in the air) Rope Climbing Jump Tutorial:

Start Hold down the arrow keys " key and " key to run to the right When you are almost to the rope, press the spacebar to jump up and climb on the rope Immediately release the " button (the character just touches the rope and release it the moment)" key does not release Complete the rope climbing jump Note: The process must be done in one go (the space bar can also be replaced by the right mouse button) When you are tired of upgrading or playing money, you may wish to play reverse jump and rope climbing jump to improve the coordination between your fingers and the brain, and you can also relax the tired brain! 3.

Ultimate Jump (Reverse Jump + Rope Climbing Jump) Appearance: See** Ultimate Jump Tutorial: It is said that after the rope climbing jump is completed, quickly press "Press at the moment of landing" This is a difficult action).

You draw a sketch and send it up.

It depends on how many floors you have, if the floor is low, it will be easy to do, and if it is high, you will have a scaffolding or something.

1: Let the safety gear operate and protect it. Then use the hoist to lift the counterweight and loosen the wire, it's as simple as that, if there is too much empty underneath, make a scaffolding or something.

2: It is the crane car, and the method is similar to the above.

It's pretty much the same as my method, and it's basically changed like this.

Wire ropes with long service life and highly stable and reliable quality.

At present, the world's wire rope field for the first time to take prevention and control measures for fretting fatigue is the patented technology of the production of phosphating coated wire rope, rope wire after manganese phosphating or zinc-manganese treatment, the surface wear resistance and corrosion resistance of the wire is comprehensively improved, not easy to wear and not easy to corrode so that the fatigue life is greatly improved, the fatigue life is three times that of the same structure smooth wire rope, and the highest test value comparison has reached an astonishing four times. It can be verified by fatigue test, if you have the ability to fatigue life, you can do your own comparative test, the test results are the most credible, the service life of the wire rope is proportional to the fatigue life, the fatigue life is long, the service life is extended in the same proportion, the use cost is lower, and the stability is better. Because the supply exceeds demand, phosphate-coated wire rope is currently difficult to buy, and you need to ask a few more wire rope manufacturers for reference only.

Seek advice on a step elevator with a few counterweight counter rope sheaves.

It's just for the sake of the corners.

I've been working in elevators for 10 years and haven't seen what you said.

According to the national standard, the replacement of safety components needs to be declared to the special department (section) of the Technical Supervision Bureau for major maintenance projects, and the construction can only be carried out after approval, otherwise it is illegal, and if someone reports it within two years, the party and the user will be punished. The safety components include the brake, the main engine, the wire rope, the traction wheel, the speed limiter, the door lock, etc., and the counterweight anti-rope wheel does not seem to be. However, the local technical supervision bureaus have different perceptions of the national standard, and it is best to go to the local special office (section) to inquire before construction, so as not to trouble!

The main function is to change the direction of the wire rope, that is, to change the direction of the wire rope.

The commonly used wire rope varieties for lifting equipment are as follows:

1.Phosphate coated wire rope (Chinese patent), the steel wire is phosphated by manganese or zinc-manganese, the wear resistance and corrosion resistance of the steel wire surface are comprehensively improved, the composite effect of phosphate film and grease can effectively inhibit the occurrence of fretting wear, completely solve the wear problem of wire rope, the fatigue life is 3 times that of the smooth wire rope with the same structure, and the fatigue life can be verified through the fatigue test (the most credible fatigue test is done in person), which is an upgraded product of the smooth wire rope. It can also be used instead of galvanized steel wire rope with a thin zinc layer (which can be tested by salt spray test or compared with corrosion resistance), with long service life, lower unit cost and better stability.

2.Galvanized steel wire rope, including hot-dip galvanizing and electro-galvanizing, generally speaking, the hot-dip galvanized zinc layer is thick, and the electro-galvanized zinc layer is thin.

3.Stainless steel wire rope, mainly 304 or 316 stainless steel, has excellent anti-corrosion effect but is expensive.

4.Plastic-coated wire rope, based on carbon wire rope, the outer layer is coated with polyethylene, polypropylene or nylon.

5.Smooth wire rope, short service life, market demand sharply reduced, will be phosphated coated wire rope completely eliminated.

6.Wire rope for mooring in marine engineering.

7.Cable wire rope.

For lifting machinery used in atmospheric environments, manganese-phosphated coated wire ropes are preferred, hot-dip galvanized-phosphating double-coated wire ropes are preferred in heavy corrosive environments, and offshore wire ropes are preferred in seawater. Please note that the name of the wire rope must be indicated in the purchase invoice, such as phosphate coated wire rope or 316 stainless steel wire rope, in order to protect their legitimate rights and interests.

If it is a traction wire rope placed at 2:1, there are anti-rope sheaves on the counterweight side and the car side, and if it is determined that the sound is made on the counterweight wheel, it may be because: 1. The anti-rope sheave on the heavy side is too much oil, resulting in abnormal noise caused by running friction to the surrounding components; 2. If the counter rope wheel bearing on the heavy side lacks lubrication, it must be lubricated with butter for maintenance; 3. Generally, low-speed and small-load elevators are maintenance-free bearings, and the corresponding bearings need to be replaced when there is a sound in the bearing part.

In addition, if there is only a sound on the heavy side, it is not the part of the reverse rope wheel, or it may be that the pressure plate on the top of the weight is loose, causing the elevator to make a sound when it is running.
