Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The novel locking piece of locking device latch hook connection iron outside goat as attached figure 1 to 6, the utility model discloses the goat model that corresponds is S700K, and the latch hook connection iron 1 of goat is bolted on rail 3 through two horizontally arranged fixing bolt 2, be provided with the pilot pin 4 on the connection iron 1. The positioning bolt 4 is located between the two fixing bolts 2 and located in the middle. The two fixing bolts 2 and the positioning bolt 4 are on the same horizontal straight line. The positioning bolt 4 is a part of the original anti-loose base of the S700K type switch machine, and reference can be made to fig. 2 and 5. The positioning bolt 4 is composed of two cylinders with different radiuses, and a hole is formed in the front end of the positioning bolt 4 and used for fixing the anti-loosening piece and preventing the anti-loosening piece from being separated from the positioning bolt 4.
The anti-loosening element assembly comprises a first anti-loosening element 5 and a second anti-loosening element 6. The original single anti-loosening piece is difficult to install two anti-loosening holes simultaneously during installation, and the installation and the disassembly are very inconvenient. The original anti-loosening sheet is shown in fig. 6. The two split anti-loosening sheets can be respectively installed, the situation that two holes compete for positions is avoided, and the installation is simple and convenient.
The first anti-loosening sheet 5 is provided with a first positioning hole 7 and a first anti-loosening hole 8, and the second anti-loosening sheet 6 is provided with a second positioning hole 9 and a second anti-loosening hole 10. The first positioning hole 7 and the second positioning hole 9 are matched with the positioning bolt 4 in an inserted mode, and the first anti-loosening hole 8 and the second anti-loosening hole 10 are respectively sleeved outside the nuts 11 of the two fixing bolts 2.
First anti-loosening sheet 5 and second anti-loosening sheet 6 are close to the one end of keeper 4 all is provided with down concave surface 12, just the lower concave surface 12 of first anti-loosening sheet 5 and second anti-loosening sheet 6 is laminated relatively. The thickness of the anti-loosening element that the securing bolt 4 can accommodate is limited. The arrangement of the lower concave surface 12 can enable the thickness of one end of the first anti-loosening sheet 8 and one end of the second anti-loosening sheet 10, which are far away from the positioning bolt 4, to be larger, and the anti-loosening sheets are not easy to fix the nuts due to train vibration.
The upper edge and the lower edge of the first anti-loosening sheet 5 are both provided with positioning blocks 13, the upper edge and the lower edge of the second anti-loosening sheet 6 are both provided with positioning grooves 14, and the positioning blocks 13 are correspondingly matched with the positioning grooves 14. The positioning block 13 and the positioning groove 14 enable the first anti-loosening sheet 5 and the second anti-loosening sheet 6 to be mutually associated and restricted after being installed, and the anti-loosening effect is good.
One side of the connecting iron 1 close to the steel rail 3 is the inner side, and the other side of the connecting iron 1 far away from the steel rail 3 is the outer side. The second anti-loosening sheet 6 and the first anti-loosening sheet 5 are sequentially inserted into the positioning bolt 4, namely the second anti-loosening sheet 6 is positioned on the inner side, and the first anti-loosening sheet 5 is positioned on the outer side. The bottom of the positioning groove 14 is provided with an extending piece 15 extending inwards. The front end face of the positioning block 13 protrudes out of the inner side face of the first anti-loosening piece 5. The arrangement of the extension piece 15 enables the matching area of the positioning block 13 and the positioning groove 14 to be larger, the relevance is enhanced, and the anti-loosening effect is improved.
The bottom of the positioning slot 14 is provided with a middle slot 18, and the middle slot 18 extends to the extending piece 15 along the axial direction of the positioning bolt 4. And a middle block 19 is arranged on one side, attached to the positioning groove 14, of the positioning block 13. The middle block 19 is correspondingly matched with the middle groove 18, and the length of the middle block 19 is smaller than that of the positioning block 13. The arrangement of the middle block 19 and the middle groove 18 further improves the relationship between the first locking piece 5 and the second locking piece 6 to prevent looseness. When the first anti-loosening piece 5 is installed, the length of the middle block 19 is smaller than that of the positioning block 13, so that the middle block 19 is prevented from being in inserted connection with the middle groove 18, and the first anti-loosening piece 5 is difficult to install. The middle block 19 is provided with a margin in the middle groove 18, so that the installation is convenient.
First anti-loosening hole 8 and second anti-loosening hole 10 are the star of twelve awn, and the interior limit of the star of twelve awn is laminated mutually with the outside of nut 11, screens each other, and locking is not hard up effectually, and because leave controllable surplus, it is also more convenient to install.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
