In-furnace feeding and discharging driving chain

Abstract

The utility model relates to the technical field of chains, and discloses an in-furnace feeding and discharging driving chain which comprises chain plates, a chain rolling shaft is arranged between the two parallel chain plates, the chain rolling shaft comprises a front combined rolling shaft and a rear combined rolling shaft, and the front combined rolling shaft and the rear combined rolling shaft are detachably installed. The front combined rolling shaft and the rear combined rolling shaft wrap the pin shaft, and the two ends of the pin shaft are movably installed on the two chain plates respectively. When the chain roller is used for oil injection and lubrication, lubricating oil can enter the lubricating oil channel from the oil injection holes formed in the front combined roller body and the rear combined roller body of the chain roller, and therefore a pin shaft can be conveniently lubricated; and in the later period, if the chain rolling shaft is seriously abraded, the chain rolling shaft can be replaced by detaching the screws connected between the front combined rolling shaft and the rear combined rolling shaft, and the operation is very convenient and rapid.

Description

Technical Field

[0001] The utility model belongs to the technical field of chains, and in particular relates to a driving chain for feeding and discharging materials in a furnace. Background Art

[0002] The drive chain for feeding and discharging materials in the furnace is a necessary drive unit for driving the furnace body to process steel parts. Due to the high temperature of the furnace body, the wear of the chain components caused by thermal expansion is also relatively large, so a special oiling component will be set up to oil the chain rollers to improve the lubrication effect;

[0003] However, the current chain rollers are installed in an integral manner. If they are severely worn in the later stage, replacement requires disassembly of the shaft, which is very cumbersome. In addition, the lubricating oil only covers the surface of the roller, and there is no guarantee that the lubricating oil will enter the inner core of the roller for lubrication.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A driving chain for feeding and discharging materials in a furnace, comprising a chain plate, a chain roller is arranged between two mutually parallel chain plates, the chain roller comprises a front combined roller and a rear combined roller, and the front combined roller and the rear combined roller are detachably mounted;

[0007] The front combined roller and the rear combined roller are wrapped around the pin, and both ends of the pin are movably mounted on the two chain plates respectively;

[0008] Lubrication units are provided on both the front and rear combined rollers to improve the lubrication effect of the chain rollers on the pins.

[0009] As a preferred embodiment of the present invention, the front combined roller and the rear combined roller are respectively provided with corresponding front screw holes and rear screw holes.

[0010] As a preferred embodiment of the present invention, the lubrication unit includes an oil filling hole opened on the waist of the front combined roller and the rear combined roller, and a lubricating oil channel connected to the oil filling hole is opened on the inner side of the front combined roller and the rear combined roller.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] When the utility model is performing oil injection lubrication, the lubricating oil will enter the lubricating oil channel from the oil injection holes provided on the front combined roller and the rear combined roller of the chain roller, which can facilitate the lubrication of the pin shaft; if the chain roller is seriously worn in the later stage, the screws connecting the front combined roller and the rear combined roller can be removed and replaced, which is very convenient and quick.

[0013] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
