In addition, the push plate 12 of the embodiment avoids the protrusion of the rock wall, and simultaneously, the contact between the plane of the push plate and the rock wall is changed from point contact into double parallel line contact, so that the deviation rectification stability is improved.
In the present embodiment, as shown in fig. 6, the pushing plate 12 includes a bottom plate 121 and a top plate located above the bottom plate 121, and the top plate is provided with an avoiding groove 124.
The bottom plate 121 and the top plate of the present embodiment are separately provided, and the top plate being located above the bottom plate 121 means that the top plate of the present embodiment is stacked above the bottom plate 121 in the thickness direction. And the top plate of the present embodiment is connected to the bottom plate 121 by the connecting means 123. The connecting device 123 may be a detachable structure or a non-detachable structure.
However, in other embodiments not shown in the drawings, the bottom plate and the top plate are integrally provided to form the push plate, and in this case, there is no division between the bottom plate and the top plate in the thickness direction of the push plate. The upper side of the push plate in the thickness direction is directly provided with an avoiding groove. The integrally provided push plate can be manufactured, for example, by forging or the like.
In some embodiments, the top plate includes two partial top plates 122 respectively located at both sides of the escape slot 124, and a gap between the two partial top plates 122 forms the escape slot 124. Specifically, in the present embodiment, as shown in fig. 6, the two partial ceiling plates 122 are independently provided. And the two sub-ceiling plates 122 are respectively connected to both lateral sides of the bottom plate 121 by connection means 123.

For example, a slot is made directly in the middle of the top plate. The avoiding groove can penetrate in the thickness direction of the top plate or can not penetrate in the thickness direction of the top plate. The avoidance groove is formed in the first rock wall, and the width and the depth of the avoidance groove are larger than those of the first rock wall protrusion, so that the avoidance effect is achieved.
The avoidance groove 124 of the present embodiment is configured to receive the first rock wall projection 51 for the avoidance effect. In the present embodiment, the width and depth of the avoiding groove 124 are larger than the height and width of the first rock wall protrusion 51, so as to achieve the avoiding effect.

The base plate 121 is rotatably connected to the correcting body 11. The upper end of the bottom plate 121 of this embodiment is bent toward the deviation rectifying body 11 to cover the space between the bottom plate 121 and the deviation rectifying body 11. During the operating condition, should bend and can prevent to mill the in-process upper portion and drop the stone and produce the extrusion to deviation correcting device inner structure. In the embodiment, the deviation rectifying main body 11 includes a base and a plurality of internal structures, such as a four-bar linkage, an oil cylinder, etc., disposed between the bottom plate 121 and the base. Therefore, the upper end of the bottom plate 121 of the present embodiment is bent to protect the internal structures.
Preferably, the lower end of the bottom plate 121 of the present embodiment is also provided with a bend. The second deviation correcting device 2 may have the same structure as the first deviation correcting device 1 of the above embodiment. However, since the second rock wall projection 52 does not affect the operation of the second deviation correction device 2, the push plate of the second deviation correction device 2 can also be provided as an unslotted flat plate structure.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
