The utility model discloses a set up the recess on the welt body, set up the bolt hole in the recess to play the guard action to fixing bolt, prevent that fixing bolt from being worn and torn along with the welt body, prevent that the nut from producing the phenomenon that the welt drops after being worn and torn.
Description
Technical Field
The utility model relates to a mine drop shaft protection technical field specifically is a wear-resisting welt of ore drop shaft concrete wall face.
Background
In the mine, the ore pass through that the ore pass through is the passageway of the perpendicular transportation of mineral, because hard ore will pass through in the pass through ceaselessly, the protection of welt can all be installed to the concrete wall of pass through usually, and the welt adopts wall-hanging installation, and the construction bolt of welt is worn and torn by the ore that passes through simultaneously with the welt, when the nut of bolt was worn and torn, the phenomenon that the welt drops appears easily. And when the lining plate is replaced, the nut of the bolt is ground flat, so that the bolt is difficult to take out, and the replacement efficiency of replacing the lining plate is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough that exists among the prior art, provide a wear-resisting welt of ore drop shaft concrete wall, the construction bolt who has solved the drop shaft welt among the prior art is worn and torn by the ore of process simultaneously with the welt, when the nut of bolt is worn and torn, appears the phenomenon that the welt drops easily to and when changing the welt, because the nut of bolt is worn down, the bolt is difficult to take out, influences the problem of the change efficiency of changing the welt.
In order to realize the purpose, the utility model discloses a technical scheme be:
the utility model provides a wear-resisting welt of ore drop shaft concrete wall, includes the welt body, the several recess has evenly been seted up on the welt body, evenly be equipped with the several bolt hole in the recess at welt body both ends, the both sides of recess are the gusset, the welt body is through to the downthehole fixing bolt of squeezing into of bolt with welt body fixed mounting on drop shaft concrete wall, fixed mounting has a lug on one of them gusset on the welt body, the lug is located the middle part of gusset, the lug with the gusset is the integrated into one piece structure.
Further, the welt body is square structure, all be equipped with two bolt holes in the recess at welt body both ends, the bolt hole all is located four angles of welt body.
Further, the fixing bolt is a ground angle bolt, and the fixing bolt penetrates through the bolt hole to fixedly install the lining plate body on the concrete wall surface of the chute.
Further, the bolt holes are all countersunk holes.
The utility model discloses a set up the recess on the welt body, set up the bolt hole in the recess, pass the bolt hole in the recess by fixing bolt with welt body fixed mounting on the drop shaft concrete wall. When having the ore through in the drop shaft, the ore at first wearing and tearing be the gusset on the welt body, and still pile up the slay in small, broken bits easily in the recess between two gussets, the slay covers on the fixing bolt of recess, and fixing bolt plays the guard action, and when the gusset on the welt body was ground flat, it can to take out fixing bolt and change the welt. The utility model discloses can guarantee that fixing bolt is just to fixing bolt wearing and tearing after the welt is ground to be flat (life-span has been to need to be changed), the ore can prevent effectively that fixing bolt's nut from being along with the welt when being ground to be flat, the phenomenon that takes place the welt and drop has improved the life of welt, when changing the welt simultaneously, fixing bolt's nut still is intact, conveniently takes out the change, has improved the change efficiency of welt.
