A V-shaped guide rail for a down-the-hole drilling rig

Abstract

The invention belongs to moving guiding mechanisms and particularly relates to a V-shaped guide rail for a down-the-hole drill. The V-shaped guide rail comprises a strip-shaped V-shaped protrusion and a sliding block, wherein the strip-shaped V-shaped protrusion is arranged on a base plate, and the sliding block is provided with a V-shaped groove and matched with the protrusion. Two inclined planes of the V-shaped protrusion are provided with stainless steel layers, the stainless steel layers can have the effect of abrasion resistance and corrosion resistance, and nylon layers are arranged on groove walls of the V-shaped groove of the sliding block simultaneously or independently to reduce friction and abrasion. According to another technical scheme, the nylon layers adhere to the two groove walls of the V-shaped groove of the sliding block, the technical scheme can be implemented independently and can also be implemented simultaneously with another technical scheme, and the nylon layers can greatly reduce friction and abrasion.

Description

technical field [0001] The invention belongs to a motion guiding mechanism, in particular to a V-shaped guide rail of a down-the-hole drilling machine. Background technique [0002] Guide rail is a commonly used structure in mechanical equipment. Its function is to limit the motion unit to move on a specified path. There are many kinds of guide rails in the prior art, including sliding guide rails and rolling guide rails. There is a sliding fit between the sliders, so there will inevitably be friction between the guide rail and the slider. Even if a large amount of lubricant is applied to the mating surfaces of the two, the guide rail and the slider will still vibrate after a long period of sliding. Abrasion occurs, especially in the occasions where the working conditions are relatively harsh or the mechanical vibration is relatively severe. Spilled sewage can also corrode the guide rails and cause the guide rails to rust. Contents of the invention [0003] The object of...
