Description

Technical Field

[0001] This utility model relates to the field of mining machinery and equipment technology, specifically a novel oil injection joint. Background Technology

[0002] An oil injection connector is a device used for mechanical lubrication. It is one of the important components of a multi-rope friction hoist, which is a type of mining machinery used for lifting minerals, personnel, and materials. Multi-rope friction hoists are classified into two types according to their layout: shaft type and ground type.

[0003] The sheave of the multi-rope friction hoist is located high above the shaft tower. When oil is injected, workers need to climb to the sheave platform on the shaft tower. The oil injection process is a high-altitude operation and is highly dangerous. Due to the special nature of sheave oil injection, the mine needs to suspend production during the oil injection process, which affects the efficiency of production and processing.

[0004] There is an urgent need for new types of oil injection fittings to address the technical defects mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a novel oil injection connector to solve the problem of inconvenient oil injection during operation mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel oil injection connector, comprising a fixed connector and a rotary connector. A stationary ring is fixedly connected to the right side of the fixed connector, and a rotating ring is fixedly connected to the outside of the rotary connector. The rotating ring is rotatably embedded inside the stationary ring. A spindle connector is fixedly connected to the right side of the rotary connector. A first oil injection channel is provided inside the fixed connector, and a second oil injection channel is provided inside the rotary connector. A cleaning port is provided on the left side inside the fixed connector. A sealing plate is detachably installed on the left side of the fixed connector. A mounting bolt is threaded onto the sealing plate. A sealing plug is fixedly connected to the right side of the sealing plate. A connecting pipe is fixedly connected to the right side of the fixed connector. A third sealing ring is fixedly connected inside the rotary connector, and a second sealing ring is fixedly connected to the outside of the connecting pipe. An oil receiving hole is provided at the top of the interior of the fixed connector.

[0007] As a further technical solution of this utility model, the oil receiving hole is provided with a threaded groove inside, and the oil receiving hole is connected to the first oil injection channel.

[0008] As a further technical solution of this utility model, the connecting pipe passes through the moving ring and is embedded inside the rotary joint, and the connecting pipe is connected to the second oil injection channel.

[0009] As a further technical solution of this utility model, a sealing groove is provided on the inner side of the third sealing ring, and the second sealing ring is embedded in the sealing groove.

[0010] As a further technical solution of this utility model, a first sealing ring is fixedly connected between the connecting pipe and the fixed joint, and the first sealing ring is a TC skeleton oil seal ring.

[0011] As a further technical solution of this utility model, the sealing plug is embedded inside the cleaning port, an O-ring is fixedly connected to the outside of the sealing plug, and the mounting bolt is embedded inside the fixing joint in a threaded connection.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the new oil injection connector not only realizes the function of oil injection during operation and the function of easy cleaning, but also realizes the function of enhanced oil injection sealing.

[0013] By setting up a fixed joint, a first oil injection channel, an oil inlet hole, a stationary ring, a moving ring, a rotary joint, a main shaft joint, and a second oil injection channel, when using the oil injection joint, the main shaft joint on the rotary joint is connected to the connection part of the main shaft of the sheave. When the rotary joint is stably connected to the end of the sheave main shaft, the second oil injection channel inside the rotary joint is connected to the oil injection hole at the end of the sheave main shaft, and the oil pipe is connected to the oil inlet hole of the fixed joint. The oil pipe and the sheave main shaft are kept horizontal. During the rotation of the sheave, the fixed joint and the oil pipe do not rotate with it, thus achieving a stable oil injection effect.

[0014] With a sealing plate, sealing plug, cleaning port, mounting bolts, and O-rings, the cleaning port on the left side of the fixed joint makes it easy for workers to clean the oil inside the joint. When cleaning, first remove the mounting bolts from the sealing plate, then pull the sealing plug from the sealing plate out of the fixed joint, and then clean the first oil injection channel inside the fixed joint. The sealing plug can enhance the sealing effect of the installation and prevent oil leakage. This structure realizes the function of easy cleaning.

[0015] By incorporating a connecting pipe, a first sealing ring, a second sealing ring, a sealing groove, and a third sealing ring, lubricating oil can enter the second oil injection channel of the rotary joint through the first oil injection channel of the fixed joint. During the oil injection process, the connecting pipe can extend into the interior of the second oil injection channel. While the oil is being injected, the second sealing ring rotates within the sealing groove of the third sealing ring. The second and third sealing rings enhance the double-layer sealing effect, preventing oil leakage. This structure improves the sealing performance of the oil injection. Attached Figure Description
