Description

Novel gantry crane plays to rise wire rope lubricated device

Technical Field

The utility model belongs to the technical field of building engineering equipment, concretely relates to novel gantry crane plays to rise wire rope lubrication device.

Background

The hoisting steel wire rope of the gantry crane is an important part and a wearing part, the service life of the hoisting steel wire rope is very important to the obtained maintenance, and the main maintenance of the steel wire rope is to perform oil coating or greasing lubrication on the steel wire rope. Under the same conditions, the life of a well lubricated rope may be 3 to 4 times longer than a poorly lubricated or unlubricated rope. However, the steel wire rope is used as a linear moving part, the whole section of the steel wire rope is difficult to lubricate well through a fixing device, especially for the steel wire rope close to a lifting appliance, because the steel wire rope is suspended in the air and is difficult to lubricate, and the working condition is the worst, the steel wire rope at the section is easy to damage, and the replacement period of the whole steel wire rope is shortened. The general afterbody of the play to rise wire rope of portal crane is convoluteed on the reel that rises in the computer lab that rises, upwards through last column bend pulley, trunk of the trunk portion pulley, will play to rise wire rope head and be connected with lifting hook, hoist etc. its installation arrangement form is as shown in figure 1:

the common gantry crane manually coats lubricating grease on the steel wire rope at a lifting reel or installs a fixed steel wire rope oiling device near a bend pulley of an upper rotating column so as to lubricate the steel wire rope. However, due to the limitation of the travel of the steel wire rope, the steel wire rope in front of the lubricator cannot be automatically lubricated, and the lubricating grease can be manually applied to the position near the pulley like the head of the nose bridge, as shown in fig. 2.

The existing scheme for additionally installing the automatic oiling device for the steel wire rope is an advanced solution. The steel wire rope oiling device provides grease through the electric lubricating pump, and the labor intensity of personnel is greatly reduced. However, due to the limitation of the wire rope stroke, the A, B, C section of the wire rope in front of the oiling device cannot be automatically lubricated, and manual lubrication is still needed to be manually performed at the pulley like the front part of the nose bridge, as shown in fig. 3.

Therefore, in the prior art, pulleys (such as a lifting pulley at the head of the nose bridge, a tail pulley, etc.) for carrying the steel wire rope in the gantry crane are arranged into a pulley device capable of automatically injecting lubricating oil so as to ensure that the bearings are always in a good lubricating state, as shown in fig. 4. However, in the practical use of the gantry crane, the pulley is one of the most frequently operated components, and in order to ensure that the pulley bearing can be sufficiently lubricated, in the arrangement of the automatic lubricating device, the bearing is often filled with a large amount of grease, and the old grease is squeezed out by the new grease, so that the bearing can be operated in a good lubricating environment. However, under the condition of excessive lubrication, the extruded old grease can overflow through the gap between the bearing sealing cover and the shaft, and workers need to clean the extruded grease regularly. Based on this, the utility model discloses lifting pulley to current reforms transform, provides a novel gantry crane plays to rise wire rope lubricating arrangement, makes the old grease of extruding pass through the pipeline and reachs the pulley grooving, through the extrusion between wire rope and the grooving, makes the grease evenly wrap up on wire rope.
