Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is described in detail with reference to the accompanying drawings and embodiments:

referring to fig. 1 to 3, a chain protector, includes base member 1, base member 1 is fixed on the track roof beam of chain drive, base member 1 corresponds with the thrust wheel position on the track roof beam, the utility model discloses by two base member 1 bilateral symmetry sets up, two the interval of base member 1 matches with the width of chain or track, and the centre is through first crossbeam 2 fixed connection, the cross section of base member 1 is L type structure, and the outside is equipped with the floor structure of reinforcing structure intensity, and it includes first floor 11 and second floor 12, second floor 12 quantity is two, relatively parallel vertical setting is fixed in on the lateral wall of base member 1, first floor 11 is annular floor structure, set up in on base member 1 periphery profile and with second floor 12 is connected, can improve the intensity of structure; and a hollow groove 15 is formed between the two second rib plates 12, so that the second rib plates can be matched with a thrust wheel on a track beam, and the interference phenomenon is avoided.

The bottom of the base body 1 is provided with a mounting hole 13 for connecting and fixing with a track beam driven by a chain, a through hole 16 for mounting the first cross beam 2 is arranged at the position of the side wall of the base body 1 close to the lower end, the first cross beam 2 can be finely adjusted by penetrating through the through hole 16, so that a better distance is kept between the two base bodies 1, and the two base bodies 1 are fixed after being adjusted; the utility model discloses a wear-resisting part, including base member 1, bolt 5, gasket 6, bolt 5, base member 1 lateral wall is close to upper end department and is equipped with a plurality of connecting hole 14 that is used for installing bolt 5, base member 1 inboard is connected with wearing parts 4, be equipped with a plurality of on wearing parts 4 with the corresponding screw hole 41 of connecting hole 14, wearing parts 4 with base member 1 is connected fixedly through bolt 5 and gasket 6, bolt 5 install the back wear-resisting part 4 inboard expose, avoid interfering the operation of chain or track.
