Description

Technical Field

[0001] The utility model relates to a lubricating device for a conveying chain and belongs to the technical field of chain lubrication. Background Art

[0002] Chain drive is a widely used method in mechanical transmission, but in most cases, many companies ignore the importance of chain lubrication. As a result, the life of industrial chains is shortened and the frequency of replacing the entire chain set is increased, thereby increasing maintenance costs. Currently, most chains are made of high-viscosity lubricating oil or grease adhering to the chain surface. Although it can lubricate the chain teeth and chain surface, it is almost impossible to penetrate the chain pins, bushings and rollers.

[0003] In order to better protect the use of the chain, it is necessary to choose a better lubrication method. The chain oil-gas lubrication device not only saves maintenance costs, but also reduces the damage and replacement frequency of the chain. The benefits brought by the chain oil-gas lubrication are far higher than the traditional grease lubrication method. Therefore, the use of chain oil-gas lubrication device is undoubtedly the most economical solution.

[0004] The chain oil-gas lubrication device is a consumable centralized oil-gas lubrication system. In terms of lubrication method, it adopts a two-phase flow injection method in which oil and gas are mixed to automatically provide a small amount of fine lubricating oil to the chain. Since the given amount of lubricant is very small and is specifically sprayed onto the chain, the lubricating oil can penetrate into the chain pins, bushings and rollers better. It is an economical and reliable lubrication mode.

[0005] However, the chain oil and gas lubrication device in the prior art still has the following shortcomings: the lubricating oil and gas will be blown away by the wind during the injection process, which not only causes waste of oil and gas, but also causes pollution; the injection range of the nozzle is a fixed range with a limited range, which will cause injection blind spots, resulting in ineffective lubrication on both sides of the chain.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] The utility model aims at the deficiencies in the background technology and provides a lubricating device for conveying chains, which can solve the problem of lubricating oil gas being scattered by wind and ensure effective lubrication of both sides of the chain during stable movement.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0009] A lubricating device for conveying a chain, comprising a first buckle cover and a second buckle cover symmetrically arranged, wherein the inner ends of the first buckle cover and the second buckle cover facing each other are both opened, and a chain lubrication channel is formed between the inner ends of the first buckle cover and the second buckle cover facing each other;

[0010] The first buckle cover and the second buckle cover have positioning blocks and injection cavities arranged in a transverse direction inside, and the positioning blocks and injection cavities in the first buckle cover are centrally symmetrically distributed with the positioning blocks and injection cavities in the second buckle cover;

[0011] The spray chambers of the first buckle cover and the second buckle cover are both provided with nozzles arranged toward the side of the chain.

[0012] Furthermore, the first buckle cover and the second buckle cover are respectively fixed to the bottom ends of the two swing arms, the top ends of the two swing arms are hinged to the fixing seats, a telescopic cylinder is installed between the two swing arms, and the two ends of the telescopic cylinder are respectively hinged to the middle of the swing arms.

[0013] Furthermore, the fixing seat is fixedly installed above the chain running direction.

[0014] Furthermore, the swing arm is in the shape of a crank arm.

[0015] Furthermore, the positioning block is fixedly connected to the inside of the first buckle cover and the second buckle cover.

[0016] Furthermore, the nozzle installed in the first buckle cover is arranged toward the positioning block of the second buckle cover, and the nozzle installed in the second buckle cover is arranged toward the positioning block of the first buckle cover.

[0017] Furthermore, a positioning groove is provided in the end surface of the positioning block close to the nozzle, and the positioning groove is arranged to penetrate in the transverse direction.

[0018] Furthermore, the longitudinal cross-section of the positioning groove is a rectangular structure, and the positioning groove is used to accommodate the side edge of the chain.

[0019] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0020] When the chain needs lubrication, the telescopic cylinder buckles the two buckle covers on both sides of the chain through the swing arm, so that the chain is located in the chain lubrication channel formed by the two buckle covers, and the chain moves stably in the positioning groove of the positioning block. At the same time, the nozzles on both sides of the chain along the running direction spray lubricating oil and gas to effectively lubricate both sides of the chain; since the nozzles are installed inside the injection chamber, the working process is relatively sealed, which can solve the problem of lubricating oil and gas drifting in the wind.
