Rail cleaning device for crane

Abstract

The invention discloses an accessory device for a crane, particularly discloses a rail cleaning device for the crane, and belongs to the technical field of crane machines. The rail cleaning device comprises a guiding pipe arranged at the front end of a wheel through a mounting rack, wherein the guiding pipe is internally provided with a hardwood link stopper the outer diameter of which is in clearance fit with the inner surface of the guiding pipe, and the lower end of the hardwood link stopper freely falls on a rail surface. Due to the adoption of the structure, the guiding pipe is arranged at the front end of the wheel through the mounting rack, and the guiding pipe is internally provided with the hardwood link stopper the outer diameter of which is in clearance fit with the inner surface of the guiding pipe, therefore the lower end of the hardwood link stopper freely falls on the rail surface, the rail cleaning device can always fit the top of a rail, sundries on the top of the rail are thoroughly cleared away, the rail cleaning device can adapt to the uneven top of the rail, the problem that a current general rail cleaning device can not fit the top of the rail is solved, the structure is simple, the cost is low, the rail is thoroughly cleaned, the reliability is high, the price is low, and the rail cleaning device is suitable for generally popularizing.

Description

[0001] technical field [0002] The invention relates to an accessory device for a crane, in particular to a rail clearing device for a crane, which belongs to the technical field of hoisting machinery. Background technique [0003] The track clearing devices currently used on various rail-type operating cranes are generally of the fixed steel plate type. The fixed track clearing device is bolted or welded to the frame of the traveling platform, and the lower steel plate of the track clearing device maintains a certain gap with the corner running track; When the trolley is moving forward, if there are iron pieces, gravel and other sundries on the track, the steel plate at the lower part of the track clearing device will push them away, so as to avoid the large walking resistance caused by the wheels pressing on the sundries, thereby avoiding The motor is overloaded and burned to avoid accidents such as possible wheel derailment. However, since the lower steel plate of th...

[0003] The track clearing devices currently used on various rail-type operating cranes are generally of the fixed steel plate type. The fixed track clearing device is bolted or welded to the frame of the traveling platform, and the lower steel plate of the track clearing device maintains a certain gap with the corner running track; When the trolley is moving forward, if there are iron pieces, gravel and other sundries on the track, the steel plate at the lower part of the track clearing device will push them away, so as to avoid the large walking resistance caused by the wheels pressing on the sundries, thereby avoiding The motor is overloaded and burned to avoid accidents such as possible wheel derailment. However, since the lower steel plate of the traditional fixed steel plate type track clearing device must maintain a certain gap with the top surface of the track, generally 5 ~ 10mm, so when the height of the rail top is less than 5 ~ When there are debris of 10mm, this track cleaning device cannot completely remove the debris on the rail top, which may cause accidents such as burning out the motor and wheel derailment; some debris will stick to the surface of the wheel, corrode the wheel tread or cause the wheel If the diameter increases, if the diameters of the wheels on both sides are different, it will cause the crane to run deflected, and eventually lead to accidents such as derailment or rollover of the crane
