Description

Technical Field

[0001] The utility model belongs to the technical field of chain lubrication, and in particular relates to a chain lubrication device used for repairing a coal preparation machine. Background Art

[0002] Chains are generally metal links or rings, mostly used for mechanical transmission and traction. Lubricating chains can reduce friction between the chain and other moving parts, thereby saving energy and improving efficiency. Reducing friction means that less force is wasted when driving the chain, making it faster and more labor-saving to use, and also extending its service life, so the chain needs to be lubricated regularly.

[0003] The chain lubrication devices currently on the market have the following problems when used:

[0004] 1. In actual use, the traditional chain lubrication device usually needs to use a needle-tube pressing method to lubricate the chain. However, during lubrication, it is easily affected by some narrow spaces, and it is not convenient to squeeze the lubricant out of the chain. Therefore, it is not convenient to use in a narrow space;

[0005] 2. When using most chain lubrication devices, after all the lubricating liquid is used up, it is necessary to completely remove the piston, load the lubricant inside, and close the piston again after it is full. This is cumbersome to operate, so it is not convenient to operate during application. Utility Model Content

[0006] The utility model aims to provide a chain lubrication device for coal preparation machine maintenance, so as to solve the technical problems raised in the background technology.

[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows: a chain lubricating device for coal preparation machine maintenance, comprising a cylinder and an observation window, the cylinder is provided with an observation window on the outside, an external threaded ring is provided on the outside of the cylinder, the external thread of the external threaded ring is connected to a sealing cover by threads, a liquid outlet pipe is provided at the bottom of the cylinder, an internal thread is provided on the inner side of the liquid outlet pipe, an external threaded pipe is provided at the bottom of the liquid outlet pipe, the external threaded pipe is threadedly connected to the internal thread, and a metal shaped hose is provided at the bottom of the external threaded pipe.

[0008] Preferably, the outer side of the cylinder body passes through a rotating shaft sealing block, a U-shaped frame is provided on the outer side of the sealing block, a limiting plate is provided on one side of the U-shaped frame, a limiting frame is provided on the outside of the cylinder body, and the limiting plate is embedded in the limiting frame.

[0013] The utility model provides a chain lubrication device for coal preparation machine maintenance, which has the following advantages:

[0014] 1. The chain lubrication device for coal preparation machine maintenance has a structure in which a liquid outlet pipe, internal threads, external threaded pipe, sealing plate and metal shaped hose are installed at the bottom of the cylinder, so it is not limited by a narrow space. The external threaded pipe is twisted to connect with the internal threads inside the liquid outlet pipe, so that the metal shaped hose can be assembled, and the hose can be spliced ​​together in multiple sections. When lubricating the chain of the coal preparation machine, the shape of the metal shaped hose can be bent, and it can pass through a narrow space when in use, so as to reach the top of the chain and squeeze out lubricating liquid to lubricate the chain;

[0015] 2. This chain lubrication device for coal preparation machine maintenance installs sealing blocks, fixing frames, U-shaped frames, limit plates, limit frames and other structures on the outside of the cylinder, so it is convenient to add lubricating liquid. When lubricating liquid needs to be added, the limit plate on the side of the U-shaped frame is pushed to move it out of the limit frame. Since the outer surface is provided with an outward-opening sealing block, the piston does not need to be completely removed when adding lubricating liquid, so lubricating liquid can be added, which is convenient to add during application.
