Description

Technical Field

[0001] This utility model belongs to the field of chain lubrication technology, and specifically relates to an automatic chain lubrication device. Background Technology

[0002] A hoist is a large mechanical device that transports goods by changing their potential energy, such as a mine hoist or a dam hoist. Broadly speaking, elevators, overhead cranes, winches, trolleys, cranes, and gate hoists can all be called hoists. Hoists generally refer to large mechanical devices with high power and strong lifting capacity. The transportation process is completed by using a power machine to drive a flexible steel wire rope and the transported goods up and down. The steel wire rope is an indispensable and important component of lifting machinery, and the main types include phosphated coated steel wire rope, galvanized steel wire rope, stainless steel wire rope, and bright steel wire rope, etc.

[0003] Domestic utility model patent application number 202120568820.6 discloses an automatic chain lubrication device, including a housing and an oil tank. Gears are movably connected to both sides of the inner surface of the housing via rotating shafts. The chain body is connected to the surface of two of the gears. A spring is fixedly connected to the left side of the top of the housing, and an electric push rod is fixedly connected to the top of the oil tank. This utility model, through the arrangement of a water tank, water outlet pipe, nozzle, and water pump, can clean dust from the surface of the chain body. Then, activating the solenoid valve sprays oil from the oil tank onto the oil brush through the oil outlet. Activating the electric push rod pushes the oil brush downwards, bringing it into contact with the chain body. As the chain body rotates, the lubrication process is automatically completed. The combination of these structures achieves automatic lubrication, solving the problems of high labor intensity, uneven application, and long time consumption associated with traditional manual chain lubrication. The aforementioned invention causes some splashing when oil in the tank is sprayed onto the oil brush through the nozzle, resulting in oil dripping onto other components and affecting their normal operation. Furthermore, the splashed oil cannot be collected, leading to oil loss during use. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an automatic chain lubrication device, comprising a conveyor frame. Side plates are fixedly mounted on both sides of the conveyor frame, and two sets of transmission rollers are mounted between the side plates via bearings. A transmission shaft is mounted on one end of each side plate, located on one side of the transmission rollers. A transmission gear and an auxiliary gear, located in the same vertical plane, are respectively mounted on one end of the transmission shaft and one end of each set of transmission rollers. The transmission gear and the auxiliary gear are connected by a transmission chain. A drive motor is fixedly mounted on the side plate, and the output end of the drive motor passes through the side plate and is fixedly connected to the end of the transmission shaft. A lubrication pump is fixedly mounted on one side of the conveyor frame, and an oil injection frame is fixedly mounted on the inner side of the side plate.

[0005] As a further preferred technical solution of this utility model, a spare gear is fixedly installed on the transmission roller, and a transmission sprocket is fixedly installed outside the spare gear, and the transmission sprockets are connected to each other by a transmission chain.

[0006] The drive motor drives the transmission shaft to rotate, which in turn drives the transmission gears, which in turn drive the auxiliary gears via a transmission chain. Together with the transmission sprocket and chain, this causes two sets of transmission rollers to rotate, thus achieving the transmission effect.

[0007] As a further preferred technical solution of this utility model, baffles are fixedly installed at both ends of the conveyor frame. The drive motor is fixedly installed on the side plate via a diagonal brace mounting bracket. The other end of the drive shaft is fixedly installed to the side plate via a bearing.

[0008] The drive motor drives the transmission shaft to rotate, which in turn drives the transmission roller to rotate via the transmission chain belt.

[0009] As a further preferred technical solution of this utility model; a connecting plate is fixedly installed at the bottom of the oil injection frame, a positioning plate and a bottom plate are installed on the connecting plate, and the positioning plate is located at the top of the connecting plate. A lubrication brush is fixedly installed at the bottom of the positioning plate at the top position of the transmission chain.

[0010] Applying lubricant to the chain using a lubrication brush reduces friction between the chain and gears, decreasing chain wear and thus reducing transmission resistance. This solves the problem of chain wear and breakage caused by insufficient lubrication in conveyors.

[0011] As a further preferred technical solution of this utility model; an oil outlet pipe is fixedly installed at the bottom of the lubrication pump, and the oil outlet pipe is fixedly installed on the inner side of the side plate by a positioning frame. The bottom of the oil outlet pipe passes through the oil injection frame and is connected to a connecting oil pipe. The connecting oil pipe is laid on the positioning plate, and its end passes through the positioning plate and is connected to the lubrication brush.

[0012] The lubricating oil is delivered by a lubrication pump, and then through an outlet oil pipe and a connecting oil pipe to the inside of the lubrication brush to lubricate the drive chain.

[0013] As a further preferred technical solution of this utility model, multiple sets of guide brushes are installed through the bottom of the lubrication brush.

[0014] The guide brush is designed to guide the flowing lubricating oil, thereby preventing it from dripping onto other components and affecting them.

[0015] As a further preferred technical solution of this utility model, an oil storage rack is fixedly installed on the top of the base plate at the position of the transmission sprocket. An oil storage tank is opened inside the oil storage rack. The bottom of the oil storage rack is fixedly installed to the base plate through two sets of support frames. An oil drain pipe is installed through the bottom of the oil storage rack.

[0016] During the lubrication of the drive chain by the lubrication pump, the dripping oil is stored in an oil reservoir to prevent it from splashing onto the conveyor frame or other components, thus affecting operation and preventing oil loss. The oil drain pipe facilitates later collection and reuse of the oil.

[0017] Beneficial effects

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Lubricating oil is delivered via a lubrication pump, through an oil outlet pipe and a connecting oil pipe, and then delivered to the lubrication brush to lubricate the drive chain. During the lubrication process, an oil reservoir collects any dripping oil to prevent it from splashing onto the conveyor frame or other components, thus avoiding damage and loss of oil. The drain pipe facilitates the collection and reuse of the oil later.

[0020] 2. Multiple sets of guide brushes are installed through the bottom of the lubrication brush. The guide brushes are designed to guide the flowing lubricating oil, thereby preventing the lubricating oil from dripping onto other components and affecting other components inside the conveyor.
