Abstract

The utility model discloses an accessory device for a crane, particularly relates to a rail cleaning device of a crane, and belongs to the technical field of hoisting machinery. The rail cleaning device of the crane comprises a guide tube which is arranged at the front end of a wheel through a mounting frame, wherein a hardwood baffle block of which the outer diameter is in clearance fit with the inner surface of the guide tube is arranged inside the guide tube; the lower end of the hardwood baffle block freely falls off on the rail surface. After adopting the structure, the guide tube is arranged at the front end of the wheel through the mounting frame, and the hardwood baffle block of which the outer diameter is in clearance fit with the inner surface of the guide tube is arranged inside the guide tube, so that the lower end of the hardwood baffle block freely falls on the rail surface, the rail cleaning device can be always attached to the top of a rail, sundries at the top of the rail can be thoroughly cleaned, the rail cleaning device can adapt to unevenness of the top of the rail, and the problem that a general rail cleaning device at present cannot be attached to the top of the rail is solved. Thus, the rail cleaning device of the crane is simple in structure, low in cost, high in reliability, low in price and applicable to general popularization, and the rail is thorough to clean.

Description

The clear rail device of hoisting crane

Technical field

The utility model relates to a kind of hoisting crane accessory device, and specifically the clear rail device of a kind of hoisting crane, belongs to elevator machinery technical field.

Background technology

The clear rail device using on all kinds of rail formulas operation hoisting cranes at present, is generally fixation steel plate formula, fixed type clear rail device bolt or be weldingly fixed on walking carriage frame clear rail device bottom steel plate and corner orbit maintenance certain interval, when walking carriage is to overtake time, if there is iron plate on track, during the foreign material such as rubble, the steel plate of clear rail device bottom is pushed open, in order to avoid foreign material cause larger walking resistance on pressure wheel, thereby avoided motor overload to burn, avoid the possible wheel accident such as overstep the limit, but because the traditional clear rail device of this fixation steel plate formula bottom steel plate must keep certain gap with rail top face, general 5～10mm, so when tread has the foreign material that are highly less than 5 ~ 10mm, this clear rail device just cannot thoroughly be removed clean tread foreign material, thereby may cause burning out motor, the accidents such as wheel is derailed, some foreign material also can stick at wheel surface, corrode wheel tread or cause wheel diameter to increase, and when as different in both sides wheel diameter, can cause the operation of hoisting crane deflection, finally cause the accidents such as derailed crane or rollover.

Summary of the invention

The technical problems to be solved in the utility model is to provide the clear rail device of a kind of clear rail hoisting crane thorough, that reliability is high, cheap.

In order to solve the problems of the technologies described above, the clear rail device of hoisting crane of the present utility model, comprise the guide pipe that is arranged on wheel front end by erecting frame, be provided with the hardwood block that external diameter coordinates with guide pipe internal surface gaps in guide pipe, the lower end of hardwood block is freely dropped on rail level.

Described guide pipe cross sectional shape is curved surface shape structure or water caltrop structure.

Described cross sectional shape is that the water caltrop limit of the guide pipe of water caltrop structure is positioned on the line of centers of rail level.

Adopt after above-mentioned structure, due to what arrange, by erecting frame, be arranged on the guide pipe of wheel front end, in guide pipe, be provided with the hardwood block that external diameter coordinates with guide pipe internal surface gaps, can make thus the lower end of hardwood block freely drop on rail level and can make clearly the rail device track top of always fitting, thoroughly remove clean tread foreign material, and the injustice at energy self adaptation track top, solved the current general clear rail device tread problem of can not fitting, it is simple in structure, cost is low, and clear rail is thorough, and reliability is high, cheap, be applicable to generally promoting.

Accompanying drawing explanation

Fig. 1 is the main TV structure schematic diagram of the clear rail device of the utility model hoisting crane;

Fig. 2 is the B-B cross section structure schematic diagram of Fig. 1.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the clear rail device of hoisting crane of the present utility model is described in further detail.

As shown in the figure, the clear rail device of hoisting crane of the present utility model, comprise the guide pipe 2 that is arranged on wheel front end by erecting frame 1, in guide pipe 2, be provided with the hardwood block 3 that external diameter coordinates with guide pipe 2 internal surface gaps, the lower end of hardwood block 3 is freely dropped on rail level 4, wherein guide pipe 2 cross sectional shapes are curved surface shape structure or water caltrop structure, specifically guide pipe 2 cross sectional shapes can be for square, rhombus, rectangle or circular port etc., certainly the exterior contour of hardwood block 3 should adapt with guide pipe 2 inner chamber profiles, can make thus hardwood block 3 in guide pipe 2, be free to slide, and the Gravitative Loads due to hardwood block 3, can make it be fitted in track top always, and when track is uneven, can slide up and down with track top, and the tread of always fitting, because hardwood block 3 hardness are far little compared with track hardness, therefore hardwood block 3 in actual use weares and teares, protection track, along with the time is used more of a specified duration, the curved surface identical with rail top face can be worn and torn in hardwood block 3 bottoms, the tread of fitting completely, thoroughly tread foreign material are cleaned out, it is simple in structure, manufacture easy for installation, reliability of service is high.

When the cross sectional shape of guide pipe 2 is water caltrop structure, its water caltrop limit is positioned on the line of centers of rail level 4, can produce thus a thrust, is more conducive to rail operation clearly.
