Description
Technical Field
The utility model relates to a large-arm falling limiting device of an underground carry scraper, belonging to the technical field of engineering mechanical mining engineering.
Background
In the underground scraper, in order to reduce the impact on the lifting oil cylinder in the falling process of the large arm, a mechanical limiting block is usually designed at the tail end position of the falling of the large arm, and the mechanical limiting block is contacted to prevent the large arm from further falling, so that the lifting oil cylinder is protected. Most designs are in the lower part of big arm and preceding frame contact department welding machinery stopper now, but this kind of machinery stopper is great to the impact of big arm and preceding frame, structural strength to big arm and the spacing department of preceding frame requires higherly, and rigid contact is great to automobile body impact force moreover, influence navigating mate's travelling comfort, on the other hand sets up in big arm below, need hold up big arm when overhauing, it is limited to overhaul the space, unsafe factors such as big arm whereabouts still increase.
The utility model has the following contents:
the utility model aims to overcome the defects of the prior art and provide a scraper boom falling limiting device.
The technical scheme provided by the utility model is as follows: a large-arm falling limiting device of an underground scraper comprises a large arm of the scraper and a front frame of the scraper, and is characterized in that two sides of the large arm of the scraper are respectively connected with limiting assemblies, each limiting assembly comprises a rib plate connected with the large arm of the scraper, the rib plates are connected with a limiting mounting seat, the lower end of the limiting mounting seat is provided with a rubber base plate and a limiting plate, two ends of the limiting mounting seat are respectively detachably connected with a pressing plate, and the pressing plates press the rubber base plate and the limiting plate; a groove hole is formed between the two pressing plates, the positioning plate corresponds to the rubber base plate and the limiting plate in position, and the size of the positioning plate is smaller than that of the groove hole.
Furthermore, the lower end of the limiting mounting seat is provided with a groove, and the rubber base plate and the limiting plate are mounted in the groove.
Furthermore, threaded holes are formed in two ends of the limiting installation seat, and pressing plates are installed at two ends of the limiting installation seat through hexagon socket head bolts respectively.
Furthermore, the rib plate is L-shaped, the outer side of the large arm of the scraper is connected with one right-angle side of the rib plate, and the other right-angle side of the rib plate is connected with the limiting mounting seat.
The utility model has the beneficial effects that: the limiting component is arranged on the outer side of the large arm, so that later-stage overhaul and maintenance are facilitated. And in the material design of stopper, adopted rubber backing plate and limiting plate, after big arm and the locating plate on the preceding frame contact, can cushion through rubber, reduced the mutual impact of big arm and preceding frame, rubber backing plate has absorbed the kinetic energy of a part whereabouts simultaneously, has reduced the whole impact to the automobile body, has improved navigating mate's travelling comfort. And the pressing plates can be disassembled at the two ends, so that the rubber base plate and the limiting plate can be replaced when being worn, and the maintenance and the overhaul are more convenient.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of a spacing mount of the present invention;
fig. 3 is a side view of fig. 2.
The specific implementation mode is as follows: the following detailed description of embodiments of the utility model refers to the accompanying drawings in which:
as shown in fig. 1-3, the underground scraper boom falling limiting device comprises a scraper boom 1, a scraper front frame 9 and limiting assemblies respectively connected with two sides of the scraper boom 1, wherein each limiting assembly comprises a rib plate 2, a limiting mounting seat 3, a pressing plate 4, an inner hexagon bolt 5, a limiting plate 6, a rubber base plate 7 and a positioning plate 8. Gusset 2 is the L type, a right-angle side of gusset 2 is connected in the outside of scraper large boom 1, spacing mount pad 3 is connected on another right-angle side of gusset 2, it is fluted 11 to process at 3 lower extremes of spacing mount pad, rubber tie plate 7, limiting plate 6 is installed in recess 11 department, 3 both ends of spacing mount pad are equipped with screw hole 12 simultaneously, install clamp plate 4 respectively at 3 both ends of spacing mount pad through hexagon socket head cap screw 5, clamp plate 4 not only limits rubber tie plate 7, limiting plate 6's lateral shifting, and compress tightly rubber tie plate 7 and limiting plate 6 simultaneously. A groove hole 10 is formed between the two pressing plates 4, the positioning plate 8 corresponds to the rubber cushion plate 7 and the limiting plate 6 in position, and the size of the positioning plate 8 is smaller than that of the groove hole 10, so that when the scraper large arm 1 falls, the positioning plate 8 penetrates through the groove hole 10 and is in close contact with the limiting plate 6.
When the scraper boom 1 falls, the limiting plate 6 falls on the positioning plate 8 and contacts with the upper plane of the positioning plate 8, and the limiting plate 6 compresses the rubber base plate 7 to complete the descending limitation of the scraper boom 1. In the maintenance in later stage, only need demolish 4 rubber tie plates 7, the limiting plate 6 that renew of clamp plate just can, the both sides of scraper arm 1 all are equipped with spacing subassembly moreover, the symmetry installation, and operating space is big, maintains easy maintenance.
It should be understood that parts of the specification not set forth in detail are well within the prior art. The above examples are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
