Description

Technical Field

[0001] The utility model belongs to the technical field of wire rope lubrication, and particularly relates to a lubricating device for the luffing wire rope of a quay container crane. Background Art

[0002] At present, the luffing mechanism, hoisting mechanism and trolley mechanism of quay container cranes at container terminals are all driven by wire ropes. In order to ensure the service life, safety and reliability of the wire ropes, it is necessary for the maintenance personnel at the terminal to regularly lubricate and maintain the wire ropes wound on the quay container cranes.

[0003] At present, the method for lubricating the luffing wire rope of quay container cranes adopted by container terminals is that the maintenance personnel at the terminal hold a telescopic rod and use a brush holder to apply grease on the surface of the wire rope. However, this traditional method not only has low efficiency and high labor consumption, but also has problems such as uneven oil application and insufficient lubrication effect. Moreover, due to potential conflicts between the surrounding complex steel structures and the positions of personnel operations, it also increases the safety risks of the maintenance personnel at the terminal. At the same time, when using this method to lubricate the wire rope, limited by the arrangement position of the wire rope and the length of the telescopic rod, there is also a problem that a section in the middle of the wire rope cannot be lubricated, resulting in this section being forced to bear the erosion of the natural environment, such as rain and fog, during a service life of up to five years, thus accelerating corrosion.

[0004] In addition, in view of the special requirements for lubricating the luffing wire rope of quay container cranes, that is, the lubricant is required to have good adhesion and permeability, fluid grease is often selected as the lubricant. When using a telescopic rod for lubrication operation, the fluid grease is likely to drip or be thrown out, especially when lubricating the middle position of the wire rope, thus causing unnecessary pollution to the terminal environment and equipment.

[0005] Therefore, how to better simplify the lubrication means, improve the lubrication effect and efficiency, so as to enhance the durability and reliability of the luffing wire rope of quay container cranes, has become a major problem that needs to be solved urgently by maintenance technicians, and is also a major challenge faced by the entire industry. Content of the Utility Model

[0006] The technical problem solved by the utility model is to provide a lubricating device for the luffing wire rope of a quay container crane that can not only meet the lubrication requirements of the luffing wire rope of a quay container crane, but also be not affected by the high-altitude environment, effectively avoid the phenomenon of dripping and throwing of fluid lubricating grease, so as to solve the problems of uneven oil application, poor lubrication effect and time-consuming and laborious when manually operating a telescopic rod to lubricate the luffing wire rope of a quay container crane, thereby realizing all-round and dead-angle-free lubrication of the wire rope, improving the reliability of the luffing wire rope, and reducing its pollution to the terminal on-site equipment and environment.

[0007] To solve the above technical problems, the technical solution provided by the present utility model is as follows: A luffing wire rope lubricating device for a quay container crane, which includes a mounting frame, and a lubricating mechanism is arranged on the mounting frame. The lubricating mechanism includes a lubricating sleeve installed on the upper part of the mounting frame.

When it is necessary to lubricate the luffing wire rope of the quay container crane, the present utility model can be first hung at the high position of the wire rope to be lubricated through the traveling mechanism, and the wire rope is passed through the lubricating sleeve of the present utility model. At this time, under the action of the self-gravity of the entire lubricating device, the inner wall of the horizontal lubricating oil cavity in the lubricating sleeve will contact the wire rope, and at the same time, the entire device will slide downward along the inclined direction of the wire rope under the action of gravity, and the wire rope will be lubricated by the liquid grease in the horizontal lubricating oil cavity during the sliding process. Moreover, during this lubrication process, since the present utility model is directly hung on the wire rope and can travel along the wire rope, it will not be affected by the surrounding complex steel structures, and it can achieve all-round and dead-angle-free lubrication of the wire rope, thereby improving the reliability of the luffing wire rope; at the same time, the present utility model can also seal the liquid grease through the lubricating sleeve, reduce the dripping of the liquid grease, and thus reduce the pollution of the entire wire rope lubrication operation to the dock site equipment and environment.

[0008] Furthermore, an oil groove is arranged on the inner side wall of the horizontal lubricating oil cavity, and the oil groove facilitates the flow of the liquid grease.

[0009] Furthermore, skeleton oil seals are arranged at both ends of the horizontal lubricating oil cavity, and the skeleton oil seals ensure the sealing of the liquid grease in the horizontal lubricating oil cavity and ensure that the liquid grease in the horizontal lubricating oil cavity can be evenly applied to the wire rope.

[0010] Furthermore, the lubricating sleeve includes a semi-circular lower part and a semi-circular upper part. The lower end of the lower part is installed on the upper part of the mounting frame, and a lower connecting part and a lower arc-shaped groove are arranged at the upper end of the lower part; an upper connecting part and an upper arc-shaped groove are arranged at the lower end of the upper part. The upper connecting part and the lower connecting part are detachably connected together by fasteners, and the upper arc-shaped groove and the lower arc-shaped groove are arranged opposite to each other and form the horizontal lubricating oil cavity of the lubricating sleeve. Since the lubricating sleeve in the present utility model adopts a split structure, it is convenient for dock maintenance personnel to install and use the present utility model.

[0011] Further, the traveling mechanism includes a traveling bracket. One end of the traveling bracket is fixed to the mounting frame, and a traveling wheel is rotatably installed at the other end of the traveling bracket. The traveling wheel is detachably connected to the traveling bracket, and a traveling space is provided between the traveling wheel and the mounting frame. When using the present utility model, the present utility model can be hung on the steel wire rope through the traveling mechanism, that is, the steel wire rope can pass through the traveling space between the traveling wheel and the mounting frame, and then the present utility model can slide relative to the steel wire rope under the action of gravity to achieve relative movement with the steel wire rope.

[0012] Further, a groove is provided on the outer circumferential surface of the traveling wheel to prevent it from separating from the steel wire rope during traveling.

[0013] Further, the oil supply mechanism includes an electric oil dispenser, and the electric oil dispenser is electrically connected to a power source, and the power source is installed on the mounting frame. In this way, due to its equipped power source, it can greatly improve the convenience of lubrication and reduce the interference of wires on lubrication work during long-distance lubrication.

[0014] From the above technical solutions, it can be seen that the present utility model has the following advantages: 1. When using the present utility model to lubricate the luffing wire rope of a quay container crane, since the present utility model is not affected by the surrounding complex steel structures, it can achieve all-round and dead-angle-free lubrication of the wire rope, thereby improving the reliability of the luffing wire rope; 2. The present utility model can also seal the liquid lubricating grease through the lubricating sleeve, reduce the dripping of the liquid lubricating grease, and thus reduce the pollution of the entire wire rope lubrication operation to the terminal site equipment and environment.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figure 1 , Figure 2 shown, the present utility model provides a luffing wire rope lubricating device for a quay container crane, which includes a mounting frame, and a traveling mechanism 102, a lubricating mechanism 101, and an oil supply mechanism 103 are arranged on the mounting frame.

The highest point of the inner wall of the horizontal lubricating oil cavity 201 is slightly higher than the lowest point of the groove bottom of the groove arranged on the outer circumferential surface of the traveling wheel, so as to ensure that the wire rope can not only roll and contact with the traveling wheel, reduce the friction between the whole device and the wire rope, but also contact with the liquid lubricating grease in the horizontal lubricating oil cavity 201 to realize the lubrication of the wire rope.

[0023] In addition, an oil injection hole 203 is provided at the top of the lubricating sleeve, that is, at the top of the upper split body.

[0024] When lubricating the luffing wire rope of the quay container crane is required, the utility model can be first hung at the high-end position of the wire rope to be lubricated, and the wire rope is passed through the lubricating sleeve of the utility model. At this time, under the action of gravity, the inner wall of the horizontal lubricating oil cavity 201 in the lubricating sleeve will contact the wire rope, and at the same time, the whole device will slide downward along the inclined direction of the wire rope under the action of gravity, and the wire rope is lubricated by the liquid grease in the horizontal lubricating oil cavity 201 during this process. Moreover, during this lubrication process, since the utility model is directly hung on the wire rope and is not affected by the surrounding complex steel structures, it can achieve all-round and dead-angle-free lubrication of the wire rope, thereby improving the reliability of the luffing wire rope; at the same time, the utility model can also seal the liquid grease through the lubricating sleeve, reduce the dripping of the liquid grease, and thus reduce the pollution of the whole wire rope lubrication operation to the terminal site equipment and environment.

[0025] In addition, as a preference, the oil supply mechanism 103 preferably adopts an electric oil dispenser, and the power supply electrically connected to the electric oil dispenser is installed on the mounting rack, and a lithium battery with light weight is preferably adopted. In this way, since it is equipped with a power supply, it can greatly improve the lubrication convenience and reduce the interference of the wire during long-distance lubrication to the lubrication work.
