Abstract
The utility model relates to a large-size E type bolt, and belongs to the technical field of connection of a scraping plate and a chain of a scraper conveyer. The large-size E type bolt has the high strength and the long service life. The large-size E type bolt comprises bolts and a connecting plate, wherein the bolts are fixedly arranged at two ends of the upper part of the connecting plate and in the middle of the connecting plate, the bolts and the connecting plate are of an integrated structure through integral forging operation, steps are arranged at the bottoms of the bolts and at the upper part of the connecting plate, and wear plates are fixedly arranged on the front surface and the back surface of the connecting plate and are positioned between the two adjacent bolts. The large-size E type bolt is mainly applied to the technical field of connection of the scraping plate, the strength of the large-size E type bolt is enahced and the service life of the large-size E type bolt is prolonged.
Description
Technical field
The utility model is a kind of large specification E type bolt, belongs to scraping transporter scraper plate and chain interconnection technique field.
Background technology
E type bolt is to be connected on the scraper plate and chain of slat conveyer, scrapper conveyor is by retarder band movable sprocket in work, sprocket wheel drives chain and scraper plate circulating motion between the middle plate of intermediate channel is upper and lower, and article are transported to other one end from one end of scrapper conveyor.Small dimension E type bolt major part is one-time formed by forging, but large specification E type bolt is at present because forge difficulty, most of split-type structural that adopts, as the E type bolt of a kind of scraping transporter of the E type bolt patent record of a kind of slat conveyer of the patent No. 201020216177.2, comprise connecting panel, bolt, bolt and connector are Split type structures, and bolt hole is set on connecting panel, and bolt passes from bolt hole; Connecting panel is to consist of the mo(u)ld top half being stamped to form with sheet metal and mo(u)ld bottom half, and mo(u)ld top half and mo(u)ld bottom half cooperatively interact and be integrally welded, and mo(u)ld top half and mo(u)ld bottom half bolt hole coordinate in correspondence with each other and with the nut of bolt.Existing large specification E type bolt is all then to use bolted by fluting on its connecting panel, has reduced the intensity of connecting panel while slotting on connecting panel, easily makes connecting panel fracture, is therefore necessary to be improved.
Utility model content
The utility model is a kind of new construction proposing in order to overcome the deficiency of above-mentioned technology existence, makes E type bolt strength larger, longer service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of large specification E type bolt, it comprises bolt, connecting panel, wear plate and step, both upper ends thereof and midway location at connecting panel are all fixed with bolt, bolt and connector are one-piece construction, it is one forging molding, bolt bottom is provided with step with the top of connecting panel, at the front-back of connecting panel, is all fixed with wear plate, and wear plate is positioned at the midway location of adjacent two bolts.
The beneficial effect that the utility model compared with prior art has is: a kind of bolt of large specification E type bolt and connecting panel are one-piece construction, it is integrally casting moulding, need on connecting panel, not slot, intensity and the service life of large specification E type bolt have greatly been improved, bolt bottom, the top of connecting panel is provided with step.So just reduce forging difficulty, increased intensity simultaneously, at the front-back of connecting panel, be all fixed with wear plate, increased service life.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the front view of a kind of large specification E type bolt of the utility model;
Fig. 2 is the birds-eye view of a kind of large specification E type bolt of the utility model.
In figure, 1 is that bolt, 2 is that connecting panel, 3 is that wear plate, 4 is step.
The specific embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
As depicted in figs. 1 and 2, a kind of large specification E type bolt, comprises bolt 1, connector 2, wear plate 3 and step 4; At both upper ends thereof and the equal bolt of rear end plate 1 of midway location of connecting panel 2, bolt 1 is one-piece construction with connector 2, one forging molding; Need on connecting panel, not slot, the distance of adjacent two bolts 1 is identical.Intensity and the service life of large specification E type bolt have greatly been improved.In bolt 1 bottom, the top of connecting panel 2 arranges step 4, has so just reduced forging difficulty, has increased intensity simultaneously.At the equal fixing wear plate 3 of the front-back of connecting panel 2, wear plate 3 is positioned at the midway location of adjacent two bolts 1.Wear plate mainly works to increase service life.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
