Description

A bridge type reclaimer chain mechanism

technical field

The utility model relates to a bridge-type reclaimer, in particular to a chain mechanism on the bridge-type reclaimer.

Background technique

The Chinese patent application number 201020561603.6 discloses a four-chain transmission device for a circular bridge scraper reclaimer. The chain mechanism in the transmission device includes a first chain, and the first chain consists of several first chain shafts, several pairs of The first inner chain plate and several pairs of first outer chain plates, each first chain shaft is equipped with a first chain roller, and the first chain guide groove with a groove-shaped cross section is fixedly installed on the main beam frame of the reclaimer , the first chain matches the first chain guide groove, and when the reclaimer is running, the first chain moves in the first chain guide groove. The disadvantage of this existing chain mechanism is that the guide groove is made of tailor-welded steel plates, and the connection strength of the weld is limited. The jacked-up scraper drives the chain against the upper part of the guide groove, causing the guide groove to be easily deformed at the welding place, affecting the safe operation of production and increasing the maintenance cost, so it is necessary to improve.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

Example

Referring to FIG. 1 , a bridge reclaimer chain mechanism includes an endless chain 1 , an uplink chain guide rail 2 and a downlink chain guide rail 3 .

The endless chain 1 includes a number of chain units that are movably connected in turn, and the chain unit includes a chain roller 11 with a roller shaft 10, an inner chain plate 12 and an outer chain plate 12 that are arranged on both sides of the chain roller 11 through the roller shaft 10 in turn. The chain plate 13 and the adjacent chain units are connected by sharing the inner chain plate 12 or the outer chain plate 13 .

The up-chain guide rail 2 and the down-chain guide rail 3 are aligned up and down.

The upward chain guide rail 2 includes an upward L-shaped plate 21 and an upward L-shaped plate 22 that is attached to the upward I-shaped plate 21. The upward L-shaped plate 21 and the upward L-shaped plate 22 are respectively fixed, and the upward L-shaped plate 22 is fixed separately. The inner side of the plate 21 is the up chain guide groove 20 .
