Abstract

The invention provides a crane lubricating device which is simple in structure, good in lubricating effect and capable of effectively lubricating and maintaining the inside of a wire rope. A crane comprises a crane trolley, a cart guide rail, a wire rope and a hook. The crane trolley is arranged on the cart guide rail and moveably connected with the same; the hook is arranged under the crane trolley and connected with the same through the wire rope; the lubricating device comprises a shell, an oil tank, a spray gun and a pair of pressure rollers, the shell is detachably connected on the crane trolley, and the oil tank is fixedly connected over the shell; the pressure rollers are arranged in the shell with a gap reserved therebetween, the wire rope is penetratingly arranged between the pressure rollers, and the width of the gap is smaller than the diameter of the wire rope; the spray gun is arranged over the gap and fixedly connected with the oil tank. The crane lubricating device is ingenious in structure, simple in using mode and good in use effect.

Description

A kind of lubricating fitting of hoist

Technical field

The present invention relates to a kind of lubricating fitting, particularly relate to the lubricating fitting of wire rope in hoist.

Background technique

Wire rope is the important spare part in hoist, in daily using process, often can run into a lot of problem, as inside and outside fracture of wire, corrosion, wearing and tearing, the long-pending change of cross section metal, loose stock, jumps the problem such as silk, distortion, even ruptures time serious.At present, for the loss of wire rope, mostly adopt the method increasing lubricant oil to extend the working life of wire rope in hoist, but, these class methods are process wire rope surface mostly, and cannot effectively effectively maintain the inside of wire rope or repair, using effect be not good.

Summary of the invention

The present invention is directed to above problem, propose that a kind of structure is simple, high lubricating effect, also can play the lubrication system of hoist of effective lubrication, maintenance effect to wire rope inside.

Technological scheme of the present invention is: described hoist comprises monkey, cart guide rail, wire rope and suspension hook; Described monkey to be located on described cart guide rail and to be flexibly connected with described cart guide rail; Described suspension hook to be located at below described monkey and to connect described monkey by wire rope;

Described lubricating fitting comprises housing, fuel tank, spray gun and a pair pressure roller, and described housing is removably connected on monkey, and described fuel tank is fixedly connected on above described housing; Pressure roller described in a pair to be located in described housing and to leave gap between a pair pressure roller, and described wire rope is located in described in a pair between pressure roller, and the width in described gap is less than the diameter of described wire rope; Described spray gun to be located at above described gap and to be fixedly connected with described fuel tank.

Described hoist also comprises controller, and described controller is communicated with described wire rope and spray gun.

In the present invention, because the gap between a pair pressure roller is less than the diameter of wire rope; Therefore, when wire rope runs, the roll surface at wire rope and pressure roller is produced enough frictional force, thus be with when wire rope runs dynamic pressure roller to run simultaneously.This case can carry out intermittent oiling to wire rope after hoist is bought, and first can be located between a pair pressure roller by wire rope, then be contained on monkey by housing during use; When wire rope is descending, controller is subject to signal, thus open spray gun, be pressed into wire rope inside by gravity, spray gun pressure and the extruding force between a pair pressure roller and wire rope when making lubricant oil fall into gap, and then effective lubrication, maintenance effect are also play to wire rope inside.The delicate structure of this case, usage mode are easy and using effect good.

In figure, 1 is monkey, and 2 is wire rope, and 3 is lubricating fittings, and 31 is housings, and 32 is fuel tanks, and 33 is spray guns, and 34 is pressure rollers.

Embodiment

As shown in Figure 1-2, described hoist comprises monkey 1, cart guide rail, wire rope 2 and suspension hook in the present invention; Described monkey to be located on described cart guide rail and to be flexibly connected with described cart guide rail; Described suspension hook to be located at below described monkey and to connect described monkey by wire rope;

Described lubricating fitting 3 comprises housing 31, fuel tank 32, spray gun 33 and a pair pressure roller 34, and described housing 31 is removably connected on monkey 1, and described fuel tank 32 is fixedly connected on above described housing 31; Pressure roller 34 described in a pair to be located in described housing 31 and to leave gap between a pair pressure roller 34, and described wire rope 2 is located in described in a pair between pressure roller 34, and the width in described gap is less than the diameter of described wire rope 2; Described spray gun 33 to be located at above described gap and to be fixedly connected with described fuel tank 32.

Described hoist also comprises controller, and described controller is communicated with described wire rope 2 and spray gun 33.
