Abstract
The utility model relates to a four-chain transmission device of a circular bridge scraper fetcher, comprising scraper mechanisms, wherein the middle of each of the scraper mechanisms is connected with a middle connecting frame on which a middle guide wheel is mounted, and the middle guide wheel matches with a middle guide wheel track arranged on a main beam frame; one side of each of the scraper mechanisms is connected to a first chain connected with a driving mechanism and a first chain guide groove which matches with the first chain and is arranged on the main beam frame; a plurality of scraper mechanisms are equivalently arranged at intervals; one side of each of the scraper mechanisms is further connected with a second chain, and a second chain guide groove matches with the second chain and is arranged on the main beam frame; two sides of each of the scraper mechanisms have a symmetrical structure to form a four-chain transmission structure; and each of sprocket wheels meshed with the chains has 12 teeth. Compared with the prior art, the four-chain transmission device of the circular bridge scraper fetcher has the advantages of having small noise, greatly reducing vibration during running, stably running, having small impact force and long service life of the chains and reducing maintenance, maintenance cost and operation cost.
Description
Technical field
The utility model relates to a kind of driving device, particularly a kind of round bridge-type scraper reclaimer four chain gearings.
Background technology
The driving device of round bridge-type scraper reclaimer comprises scraping plate mechanism, link span in the middle of the middle part of scraping plate mechanism is connected to, guide wheel in the middle of on middle link span, being equipped with, middle guide wheel matches with the middle guide wheel track that is located on the girder frame, one side of scraping plate mechanism is connected on first chain that is connected with driver train, be furnished with the first chain guide groove that is located on the girder frame mutually with this first chain, the scraping plate mechanism both sides are symmetrical structure, form the double strand chain type of drive.Scraping plate mechanism is by being bolted on one of them pin link plate on the chain; The teeth number of sprocket that is meshed with each chain is 8.During operation, the drive sprocket of driver train drives the chain operation, and the scraping plate mechanism that is connected on the chain moves thereupon, and scraper plate can be scraped the material in stock ground to desired location, reaches the purpose of conveying.The driving device shortcoming of this structure is as follows: vibrate during operation, stationarity is poor, and the chain fracture is frequent, needs frequent shutdown maintenance, the operating cost height.
Summary of the invention
The purpose of this utility model provides a kind of little, chain long service life that operates steadily, vibrates, and reduces round bridge-type scraper reclaimer four chain gearings of operating cost, overcomes the deficiencies in the prior art.
Round bridge-type scraper reclaimer four chain gearings of the present utility model comprise scraping plate mechanism, link span in the middle of the middle part of scraping plate mechanism is connected to, and guide wheel in the middle of on middle link span, being equipped with, middle guide wheel matches with the middle guide wheel track that is located on the girder frame; One side of scraping plate mechanism is connected on first chain that is connected with driver train, is furnished with the first chain guide groove that is located on the girder frame mutually with this first chain; Several scraping plate mechanism equi-spaced apart are provided with; One side of each scraping plate mechanism also is connected with second chain, is furnished with the second chain guide groove mutually with second chain, and the second chain guide groove is located on the girder frame; Described scraping plate mechanism both sides are symmetrical structure, thereby form four chain gear structures; The teeth number of sprocket that is meshed with each chain is 12.
Round bridge-type scraper reclaimer four chain gearings of the present utility model compared with prior art, noise is little, vibration reduces greatly during equipment operation, operates steadily; Impulsive force is little, and the chain long service life reduces maintenance time, reduces maintenance cost and operating cost.
Description of drawings
Fig. 1 is a driving device sectional schematic diagram in the utility model specific embodiment.
The specific embodiment
As shown in Figure 1: 1 is scraping plate mechanism, utilizes metal sheet welding or bolted mode processing and fabricating.In the middle part of each scraping plate mechanism 1 middle link span 10 is arranged, by bearing pin middle guide wheel 9 is installed on middle link span 10, be furnished with middle guide wheel track 8 mutually with middle guide wheel 9, middle guide wheel track 8 is fixedly mounted on the girder frame of reclaimer.
The left side of scraping plate mechanism 1 and first chain join, first chain by several first chain rivets 4, some first inner plate 6, first pin link plate 2 are constituted, be set with the first chain roller 3 on each first chain rivet 4.The fixed installation section is that the first chain guide groove, 5, the first chains and the first chain guide groove 5 of flute profile matches on the girder frame of reclaimer, and during operation, first chain is mobile in the first chain guide groove 5.First pin link plate 2 that is positioned at the right side is captiveed joint with scraping plate mechanism 1 by bolt.
On scraping plate mechanism 1, be positioned at the first chain inboard and also be connected with second chain, second chain by several second chain rivets 12, some second inner plate 11, second pin link plate 14 are constituted, be set with the second chain roller 13 on each second chain rivet 12.The fixed installation section is that the second chain guide groove, 15, the second chains and the second chain guide groove 15 of flute profile matches on the girder frame of reclaimer, and during operation, second chain is mobile in the second chain guide groove 15.Second pin link plate 14 that is positioned at the left side is captiveed joint with scraping plate mechanism 1 by bolt.
Said structure is symmetrical set with respect to the center of middle guide wheel 9, promptly forms four chain gearings.
Many several scraping plate mechanisms 1 at interval and be arranged in parallel.
The drive sprocket that is meshed with above-mentioned each chain and the number of teeth of driven sprocket are 12.
When the driver train of reclaimer drove four row's chain operations, each scraping plate mechanism 1 moved thereupon, plays the purpose that scraper is carried.
