Description

A wire rope lubrication device

technical field

The utility model relates to a steel wire rope lubricating device, which belongs to the technical field of lubricating equipment.

Background technique

In various industries such as factories, mines, construction, transportation, etc., a large number of equipment such as cranes, hoisting machinery, and traction machinery are used, and wire ropes are indispensable and important components of these equipment. During the use of the wire rope, lubrication is often required to ensure the normal use of the wire rope. Usually the wire rope is lubricated in the following ways:

1) Manual lubrication. This method is unevenly lubricated, which is easy to cause waste, and due to the long wire rope, some parts cannot be reached;

2) Pneumatic automatic lubricator. The oil is sprayed onto the steel wire rope by spraying, and PLC control is adopted. The disadvantages are inaccurate refueling, serious waste of oil, special lubricant and high cost;

3) Internal lubrication of the wire rope. The rope core of the steel wire rope is designed to be tubular, and oil is injected inward through the pipe. The disadvantage of this lubrication method is that the strength of the steel wire rope is reduced, and the cost of the steel wire rope is increased, which does not conform to the current domestic situation;

4) Special lubrication device. The design is more advanced, the cost is expensive, the compressed air medium is required, the installation is troublesome, and it is inconvenient to replace parts such as wire ropes, and it is generally not used on cranes.

In view of the above-mentioned several lubrication methods have certain shortcomings, it is necessary to design a new wire rope lubrication device.

Utility model content

The technical problem to be solved by the utility model is to provide a simple, practical, powerless, easy maintenance and operation wire rope lubricating device.

The technical scheme that solves the above-mentioned technical problem is:

A wire rope lubricating device, which is composed of a support rod, an oil storage barrel, an oil discharge pipe, and an oil discharge valve. One end of the support rod is installed on a fixed pulley block, and the other end of the support rod is connected to the oil storage barrel. The oil storage barrel is located at the fixed Above the pulley block, an oil discharge pipe is installed on the bottom of the oil storage barrel, and an oil discharge valve is installed on the oil discharge pipe, and the nozzle of the oil discharge pipe is relative to the steel wire rope in the fixed pulley block.

In the wire rope lubricating device, there are two support rods, the lower ends of which are respectively fixedly connected to the two ends of the pulley shaft of the fixed pulley block, and the upper ends of the support rods are respectively connected to the two ends of the oil storage barrel by bolts.

In the aforementioned wire rope lubricating device, the number of oil discharge pipes at the lower part of the oil storage barrel matches the number of fixed pulleys of the fixed pulley block.

In the aforementioned wire rope lubricating device, an oil drum cover and a handle are installed on the upper part of the oil storage drum.

The beneficial effects of the utility model are:

The oil storage barrel of the utility model is installed above the fixed pulley, and the oil discharge pipe at the lower part of the oil storage barrel is opposite to the steel wire rope in the fixed pulley block. The oil drain pipe leaks to the wire rope, which has a good lubrication effect. The utility model effectively utilizes lubricating oil and reduces the waste of lubricating oil. The lubricating process does not require electric power and other power equipment to drive, and only relies on the vibration generated by the lifting or traction machinery to fill the lubricating oil, which is safe and environmentally friendly. Energy saving. The utility model has the advantages of simple structure, convenient operation and maintenance, low manufacturing cost, good lubricating effect, easy installation and disassembly, and can be widely used in various cranes, hoisting machinery, traction machinery and other equipment.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The marks are as follows among the figure: handle 1, oil barrel cover 2, oil storage barrel 3, oil drain valve 4, oil drain pipe 5, steel wire rope 6, fixed pulley block 7, fixed pulley cover 8, support rod 9.

Detailed ways

The utility model is made up of support bar 9, oil storage tank 3, oil discharge pipe 5, oil discharge valve 4.

Shown in the figure, the oil storage drum 3 is cylindrical, and is horizontally placed on the top of the fixed pulley block 7 . Oil barrel cover 2 and handle 1 are installed on the top of oil storage barrel 3, and oil discharge pipe 5 is installed on the bottom of oil storage barrel 3, and oil discharge valve 4 is installed on oil discharge pipe 5. 6 relative. The quantity of the oil discharge pipe 5 matches the fixed pulley quantity of the fixed pulley block 7, and the number of the oil discharge pipe 5 can be freely set according to the root number of the steel wire rope 6.

Shown in the figure, there are two support rods 9, their lower ends are respectively fixedly connected to the two ends of the pulley shaft of the fixed pulley block 7, and the upper ends of the support rods 9 are connected to the two ends of the oil storage barrel 3 by bolts respectively.

The utility model can be made of waste materials, and the cost is low.

When the steel wire rope 6 is lubricated, it is only necessary to open the oil drum cover 2 to add lubricating oil into the oil storage tank 3, then open the oil release valve 4, and the operator starts the crane (hoisting machinery, traction machinery, etc.), lifts the steel wire rope 6, and the grease is released. It will use the vibration generated during the operation of the equipment to naturally drive the grease in the oil storage tank 3 to vibrate, and flow into the steel wire rope 6 of the fixed pulley block 7 along the oil discharge pipe 5 to play a lubrication role. And lubricating oil can drop in the following suspension hook moving pulley block along with wire rope 6, finishes the lubrication of moving pulley simultaneously, will not cause the waste of lubricating oil. When no lubrication is needed, the oil drain valve 4 can be closed or the lubricating device can be removed.
