Technical Field

The invention particularly relates to a salt spray prevention device for a winch.

Background

The scene that the winch was used is very extensive, but the winch that the oil rig was used is because service environment is more and more abominable, and sand blown by the wind is violently spilled over, and humidity is big, and salt fog is very big, influences equipment greatly, very easily causes to store up salt, sand in the equipment, not only can reduce the operating efficiency of winch, still corrodes the inside structure of equipment easily, and to a great extent has influenced the use of winch. In the prior art, the protection of the winch only adopts a filter screen to simply filter sand and stone, and still cannot play a role in salt mist prevention and filtration.

Disclosure of Invention

The invention aims to solve the defects of the prior art, and provides a salt spray prevention device for a winch, which comprises a U-shaped hollow connecting frame and a semi-open ventilation bin, wherein the U-shaped hollow connecting frame is connected with an air inlet of a winch motor; the front wall, the rear wall and the upper wall of the ventilation bin are open, and the two side walls and the bottom wall are closed; the rear wall of the ventilation bin is connected with the horseshoe-shaped hollow connecting frame; the grid, the salt mist filter and the sand filter are sequentially inserted in the ventilation bin along the air inlet direction; the diapire in ventilation storehouse is equipped with the sand filtering mouth and deposits the sand table, the sand filtering mouth be located sand filtering filter under, deposit the sand table and be located sand filtering mouth under to the inner chamber through sand filtering mouth and ventilation storehouse switches on.

In order to better realize the salt fog prevention function of the winch, the filtering grade of the sand filter is preferably equal to or more than 0.5 mu m of dust particles in each cubic meter of air.

Preferably, the area of the end surface of the front wall of the ventilation bin is smaller than that of the end surface of the rear wall of the ventilation bin, and the ventilation bin is integrally expanded along the air inlet direction.

Preferably, the surfaces of the horseshoe-shaped hollow connecting frame and the ventilation bin are coated with antirust coatings.

Has the advantages that:

the invention is provided with a grid, a salt mist filter, a sand filter and a sand storage plate in sequence along the air inlet direction. The grid can block floating objects in the outside air; the salt spray filter can block corrosive water vapor in the air; the sand filter with the filtering grade of more than or equal to 0.5 mu m of dust particles in each cubic meter of air can block sand in the air; the sand storage plate can collect sand and stone blocked by the sand filter, and the sand and stone are prevented from influencing the ventilation effect. The limit of the service environment of the winch is effectively overcome, the problems that the winch is easy to damage and cannot continuously operate under severe environments containing sand, dust, salt mist, mold and the like in the air are solved, the service life of the winch is prolonged, the winch can obtain clean and dry high-quality air to dissipate heat, and the continuous operation and safety of the winch are guaranteed.
