Abstract
The utility model discloses an anti-drop car arrester of a drop shaft carry-scraper. The anti-drop car arrester comprises a pedestal, wherein the pedestal comprises two parallel first connecting beams; a plurality of second connecting beams are vertically arranged to crosswise connect the first connecting beams; a first stopping frame and a second stopping frame are arranged above the pedestal; the second stopping frame is in rotary connection with the pedestal; a buffer mechanism is arranged between the first stopping frame and the second stopping frame. The two stopping frames are arranged, and the buffer mechanism is arranged between the two stopping frames, when the carry-scraper is in contact with the second stopping frame, the anti-drop car arrester can buffer the carry-scraper; in the meantime, when the carry-scraper hits against the second stopping frame with sudden force, the first stopping frame can stop the carry-scraper to get better safety. In addition, when the carry-scraper finishes the ore discharging operation, and the bucket is dropped, the stopping frames cannot be broken.
Description
Technical field
The utility model relates to technical field of mining equipment, specifically the anti-fall car arrester of a kind of drop shaft scraper.
Background technology
What underground stope used unload ore deposit drop shaft unload for a long time in the operation of ore deposit by the ore of level and this level impact after friction, will cause the size of drop shaft well head to strengthen, become infundibulate, more than being greater than design size twice.And the anti-fall measure of scraper using at well head is now mounded or thwarted with a mining i beam by ore storage, ore stockpile or i iron barricade are because the restriction of scraper bucket height can not be too high, and less than after the rolling an of order of classes or grades at school, ore deposit heap or i iron will soon form a natural grade, do not have the effect that stops scraper at all.Meanwhile, the scraper travel speed using is now fast, and from heavy, the front-wheel that often occurs scraper in the time slipping shaft mouth operation or unload ore deposit is climbed up and piled up stockpile or i iron, even scraper can occur and crash into the accident of drop shaft, causes serious consequence.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned background technology, provides a kind of safe and reliable, and has the anti-fall car arrester of drop shaft scraper of pooling feature.
For achieving the above object, the anti-fall car arrester of drop shaft scraper that the utility model is designed, comprise base, described base comprises two the first tie-beams that be arranged in parallel, between described the first tie-beam, by the second tie-beam interconnection of multiple perpendicular settings, it is characterized in that: described base top is provided with the first stop bracket and the second stop bracket; Described the second stop bracket and base are rotationally connected; Between described the first stop bracket and the second stop bracket, be provided with buffer gear.
Further, described buffer gear comprises spring, and both ends of the spring is connected with the first stop bracket and the second stop bracket respectively.Like this, just play cushioning effect.
Further, described buffer gear also comprises guide peg, and described guide peg is through described spring, and its one end is fixedly connected with the first stop bracket, and the other end stretches in the pilot hole on the second stop bracket.
As preferred version, described the second stop bracket is rotationally connected by bearing pin and supporting seat, and described supporting seat is fixed on base.Like this, realize the relation that is rotationally connected between the second stop bracket and base by simple structure.
Further, the height of described the second stop bracket is greater than the height of the first stop bracket.
Further, described in
baseand be provided with reinforcing rib between the first stop bracket.Like this, in the time that the second stop bracket is violently shaken, make the first stop bracket below more firm.
The beneficial effects of the utility model are: twice stop bracket is set, and is provided with buffer gear between twice stop bracket, after scraper contacts with the second stop bracket, can play cushioning effect; Meanwhile, when scraper is in the time clashing into the second stop bracket with sudden force, after also have the first stop bracket block scraper, make more safe; Moreover, after scraper unloads ore deposit operation, while falling scraper bowl after rise, be unlikely to stop bracket to damage.
Brief description of the drawings
Fig. 1 is that the master of the anti-fall car arrester of the utility model drop shaft scraper looks schematic diagram;
Fig. 2 is the schematic top plan view of the anti-fall car arrester of the utility model drop shaft scraper;
Fig. 3 is the A-A cross-sectional schematic in Fig. 1.
In figure: base 1(wherein: the first tie-beam 1.1, the second tie-beam 1.2), the first stop bracket 2, the second stop bracket 3(wherein: pilot hole 3.1), buffer gear 4(wherein: spring 4.1, guide peg 4..2), bearing pin 5, supporting seat 6, reinforcing rib 7.
Detailed description of the invention
As shown in Figure 1 to Figure 3, the anti-fall car arrester of drop shaft scraper, comprises base 1, and described base 1 comprises between two the first tie-beam 1.1, the first tie-beams 1.1 that be arranged in parallel by the second tie-beam 1.2 interconnections of multiple perpendicular settings.When installing and using, described base 1 is imbedded underground, the upper surface of base 1 is concordant with ground or a little less than ground, and base 1 and ground are fixed, and makes described first crossbeam 1.1 perpendicular to drop shaft.Described base top 1 is provided with the first stop bracket 2 and the second stop bracket 3; Described the second stop bracket 3 is rotationally connected with base 1; Between the first stop bracket 2 and the second stop bracket 3, be provided with buffer gear 4.The first stop bracket 2 and the second stop bracket 3 are all made up of two root posts and a crossbeam, and crossbeam two ends are connected with column, like this in order to increase the intensity of stop bracket; The column of the first stop bracket 2 is fixing with two the first tie-beams 1.1 respectively, and the top of close the first tie-beam 1.1, is also positioned at the first tie-beam 1.1 one end near drop shaft; The column of the second stop bracket is rotationally connected with the first tie-beam 1.1 respectively, is also positioned at the one end near drop shaft, but distant with respect to the first stop bracket 2.
Further, described buffer gear 4 comprises spring 4.1, and spring 4.1 two ends are connected with the first stop bracket 2 and the second stop bracket 3 respectively.Described buffer gear 4 also comprises guide peg 4.2, and described guide peg 4.2 is through described spring 4.1, and its one end is fixedly connected with the first stop bracket 2, and the other end stretches in the pilot hole 3.1 on the second stop bracket 3.Like this, after contacting with the second stop bracket, scraper can play cushioning effect; Meanwhile, when scraper is in the time clashing into the second stop bracket with sudden force, after also have the first stop bracket block scraper, make more safe; Moreover, after scraper unloads ore deposit operation, while falling scraper bowl after rise, be unlikely to stop bracket to damage.
As preferred version, the second stop bracket 3 is rotationally connected by bearing pin 5 and supporting seat 6, and described supporting seat 6 is fixing
?on base 1.Like this, realize the relation that is rotationally connected between the second stop bracket 3 and base 1 by simple structure.
Further, the height of described the second stop bracket 3 is greater than the height of the first stop bracket 2.Like this, make to thwart the better effects if of scraper.
Further, described
base1 and first is provided with reinforcing rib 7 between stop bracket 2.Like this, in the time that the second stop bracket 3 is violently shaken, makes the first stop bracket 2 below more firmly and safety, and thwart fork lift truck more reliable.
