Description

Chain bucket hoist chain is in the method for tail wheel slip-skid prevention

Technical field

The present invention relates to technical field of conveying machinery, especially a kind of chain bucket hoist chain is in the anti-slip device of tail wheel and method thereof.

Technical background

Gig is when there is slip teeth in chain in operation process, gig will shut down cleaning, could continue to run after clearing up the buildup of tail wheel tooth root by hand, for the gig of cement transportation when empty machine runs, equipment normal operation, chain operates steadily at tail wheel, there is not the situation of slip teeth, but in the operation of band material after 3 ~ 4 hours, counterweight starts slowly to be lifted, when being lifted to a certain limiting altitude, then down move fast suddenly, to the impulsive force that one, chain is very large, when just starting, the period of counterweight up-and-down movement is about 10 minutes, cycle was shorter and shorter afterwards, for preventing device damage, after each discovery is beated, need hard stop inspection, after the buildup of tail wheel gear teeth root is cleaned out, continue again to run, the operation of band material is after 3 ~ 4 hours, repeat again operation conditions above, all pass through the buildup of labor cleaning's tail wheel gear teeth root after each fault, equipment just can rerun, and makes quantity-produced cement mill system can only maintain desultory production.

Summary of the invention

The invention provides a kind of chain bucket hoist chain in the anti-slip device of tail wheel and method thereof, it can solve existing gig needs regular out-of-service inspection after operation in order to avoid occur the frequent up-and-down movement of tail wheel slip teeth, counterweight thus affect the problem of the production of cement mill system.

In order to solve the problems of the technologies described above, the technical scheme of anti-slip device of the present invention is: it includes pressure gas pipeline, this pipeline is provided with a gas main, this gas main is communicated with the gas-distributing pipe extended to both sides, two outlet side bendings of described gas-distributing pipe, the nozzle inclination of each outlet side is arranged, and the inlet end of described gas main is provided with air valve.

The method of the slip-skid prevention adopted comprises the steps:

A, be that the pressure gas of 0.7 ~ 0.8MPa is guided to bottom chain bucket hoist, as winding-up source of the gas air pressure;

B, housing peripheral hardware bottom chain bucket hoist have described anti-slip device, the gas-distributing pipe of this anti-slip device is across on the both sides of described housing, the described nozzle of described gas-distributing pipe is respectively towards tail wheel end face, described nozzle is 90 ° ~ 110 ° towards the angle of described tail wheel end face, and described nozzle is just entering the tooth root of the position sprocket wheel of first tooth before engagement to chain and sprocket wheel;

C, described winding-up source of the gas is connected on the admission port of the gas main of described anti-slip device, described admission port is installed for adjusting air quantity and closing the air valve of source of the gas;

When D, described chain bucket hoist run, open air valve, pressure gas is just blowing to the tooth root that chain and tail sprocket enter the position sprocket wheel of first tooth before engagement.

Owing to have employed technique scheme, the present invention compared with prior art, has following beneficial effect:

Because anti-slip device installs on chain bucket hoist, the ash that chain roller enters the tooth root of the position sprocket wheel of first tooth before sprocket engagement can be blown clean, extruding by chain roller can not at sprocket tooth root position dust stratification, ensure that the running orbit at chain roller center is on the reference circle of sprocket wheel, actv. avoids slippery conditions and occurs, thoroughly solve the problem of the frequent up-and-down movement of counterweight, gig is able to normal operation, do not affect the production of cement mill system, cement output improves greatly, the operation power consumption of maintenance cost and cement mill system can significantly reduce, good economic benefit is created to company.

Detailed description of the invention

Below in conjunction with instantiation, the invention will be further described:

As depicted in figs. 1 and 2, include pressure gas pipeline, this pipeline is provided with a gas main 7, this gas main is communicated with the gas-distributing pipe 9 extended to both sides, two outlet side bendings of gas-distributing pipe 9, the nozzle 4 of each outlet side is obliquely installed, and the inlet end of gas main 7 is provided with air valve 8.

Chain bucket hoist chain of the present invention is in the method for tail wheel slip-skid prevention, and its step is as follows:

A, be that the pressure gas of 0.8MPa is guided to bottom chain bucket hoist 1, as winding-up source of the gas air pressure;

Anti-slip device is provided with outside B, housing 3 bottom chain bucket hoist, the gas-distributing pipe 9 of this anti-slip device is across on the both sides of housing 1, two side nozzles 4 of gas-distributing pipe 9 are respectively towards tail wheel end face, nozzle is 105 ° towards the angle of tail wheel end face, and nozzle 4 is just entering the tooth root of the position sprocket wheel of first tooth before engagement to chain 5 and sprocket wheel 6;

C, winding-up source of the gas is connected on the admission port of gas main 7 of anti-slip device, admission port is installed for adjusting air quantity and closing the air valve 8 of source of the gas;

When D, chain bucket hoist 1 run, open air valve 8, pressure gas is just blowing to the tooth root that chain 5 and tail sprocket 6 enter the position sprocket wheel of first tooth before engagement, ash is blown clean, extruding by chain roller at sprocket tooth root position dust stratification, can not ensure that the running orbit at chain roller center is on the reference circle of sprocket wheel, effectively avoids slippery conditions to occur, ensure that gig can not cause frequently beating of clump weight because of slip teeth, and then affect it and run continuously.
