Technical Field

[0001] The utility model relates to the technical field of central lubrication for semi-trailers, and specifically to a central lubrication structure for semi-trailers. Background Art

[0002] A semi-trailer has axles placed behind the vehicle's center of gravity (when the vehicle is evenly loaded), and is equipped with a coupling device that can transfer horizontal and vertical forces to the tractor; generally, a semi-trailer is a three-axle semi-trailer, and its types include eleven-meter grain bin semi-trailers, thirteen-meter grain bins, low-bed semi-trailers, and many other types; it is a heavy transportation vehicle connected to the semi-trailer head through a kingpin.

[0003] In a container terminal, there are a large number of semi-trailers, and the lubrication workload of semi-trailers is relatively large. It takes about 20 minutes to lubricate 1 semi-trailer manually. Each lubrication point usually uses the manual method to add grease point by point. Generally, 7 - 8 semi-trailers need to be lubricated every day, which is time-consuming and laborious. At the same time, repair personnel need to get into the narrow chassis space of the semi-trailer to carry out lubrication work, which is not easily noticed and there are certain safety hazards.

[0004] Therefore, we propose a central lubrication structure for semi-trailers to solve the above-mentioned problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a central lubrication structure for semi-trailers to solve the problems in the above background art, such as long lubrication time, and the need for repair personnel to get into the narrow chassis space of the semi-trailer to carry out lubrication work, which is not easily noticed and there are certain safety hazards.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A central lubrication structure for semi-trailers, including a front filling port. One side of the front filling port is provided with a rear filling port. The front filling port and the rear filling port are respectively arranged on both sides of the semi-trailer body. The front filling port and the rear filling port are respectively connected to a grease filling machine with quick connectors. One side of the rear filling port is also provided with an oil storage pipe, and the oil storage pipe serves to receive the lubricating grease transported by an external grease filling machine. There are fifteen groups of interfaces B on the oil storage pipe. One of the interfaces B is connected to one end of the rear filling port. One side of the remaining interfaces B is connected to a grease hose. The end of the grease hose far from the interface B is connected to a grease nipple. The grease nipple is used to spray out the grease and can lubricate the structures on the semi-trailer. A protective member for protection is arranged on the outer side of the grease hose, and a bushing is arranged on the outer side of the interface B.

[0007] Preferably, one end of the front filling port is connected to an oil circuit. An interface A is arranged on the outer wall of the oil circuit, and a sealing gasket is arranged on the inner wall of the interface A. The sealing gasket serves to seal.

[0008] Preferably, a hose is connected to the inner side of the oil circuit. One end of the hose away from the oil circuit is connected to a grease nozzle, and the grease nozzle is placed at the hydraulic support on the semi-trailer. There are two sets of the oil circuit, the hose and the grease nozzle, and the two sets of grease nozzles are used to lubricate the hydraulic support on the semi-trailer.

[0009] Preferably, filter screens for filtering are arranged inside both the front filling port and the rear filling port.

[0010] Preferably, the protection member includes two sets of protective sleeves and a positioning block arranged on one side of one of the protective sleeves. A positioning groove is formed on one side of the other protective sleeve, and connecting bolts for fixing are further arranged on the outer wall of the protective sleeve.
