Preferably, the hole type guide and guard device further comprises an adjusting shim, and the adjusting shim is used for adjusting the distance between the first left wear plate and the first right wear plate.
Preferably, the hole type guide and guard device further comprises a lifting hook, and the lifting hook is installed at the top of the guide and guard box body.
Preferably, the guide box body is molded by one-time casting.
Preferably, the first left wear-resisting plate, the first right wear-resisting plate, the second left wear-resisting plate, the second right wear-resisting plate and the bottom wear-resisting plate are made of hard alloy materials and are installed in a wedge-type matched mode with the guide box body.
The fastening adjusting bolt fixes and positions the wear-resisting plates on one hand, and can moderately adjust the distance between the left wear-resisting plate and the right wear-resisting plate by increasing and decreasing the number of the adjusting gaskets on the other hand.
Compared with the prior art, the invention has the beneficial effects that:
1) the guide box body is integrally cast, the strength is high, and wear-resisting plates are arranged at the positions which are easy to wear around the guide inner cavity.
2) The wear-resisting plate mounting and dismounting device is simple in structure, simple and convenient in mounting and dismounting operation of the wear-resisting plate and convenient to maintain, the guide box body can be repeatedly used, and the number and consumption of spare parts of the guide are reduced.
