Description

Anchor rod driller multiplication propulsion unit

Technical field:

The present invention relates to the propulsion plant of a kind of skyhook, particularly a kind of jumbolter.

Background technology:

Pit shaft in mining or similar operation; the tunnel; in the gallery; its top; bottom or sidewall often adopt lining cutting protection anchor pole; promptly hole in need protection place; and installation has the anchor pole that protects liner plate in this hole; above-mentioned boring is normally finished by jumbolter; jumbolter is a kind of essential equipment that is used for the tunnel active support; it collects boring; powder stick stirs; skyhook; functions such as nut is fastening are in one; usually armature boring is to dispose hydraulicdriven propulsive mechanism; the propulsive mechanism of early stage jumbolter is to adopt the one-level push structure; its structure is fairly simple; this moment, the propelling stroke of rig equaled the length that the lane space distance deducts propulsive mechanism hydraulic cylinder body itself; obviously; in extremely narrow lane space; the rig stroke that one-level advances can not be too big; therefore; the distance that the jumbolter of this structure once creeps into is the requirement that can't reach the anchor pole fitting depth of setting; during operation; need repeatedly to change drilling rod and just can finish bore operation, operating efficiency is reduced greatly.At the problems referred to above, the dealer proposes improved technical scheme, adopt jumbolter two-stage push structure, promptly in the outer hydraulic cylinder of push structure, be provided with an inner cylinder body that can move back and forth, and movably be provided with a plunger in the inner cylinder body, skyhook rig on the plunger, during operation, work fluid promotes inner cylinder body (and plunger) and finishes jumbolter first order propelling stroke in the hydraulic cylinder outside, thereupon, the fluid of working in inner cylinder body promotes plunger and finishes jumbolter second level propelling stroke, thereby the two-stage push structure and the one-level push structure that form jumbolter compare, and it once creeps into stroke can increase by 1.5 to 2.0 times, but, in limited lane space, the outer hydraulic cylinder of propulsive mechanism and the length of inner cylinder body all are subjected to very big restriction, and above-mentioned two-stage push structure still can't solve once creeps into the requirement that reaches the anchor pole fitting depth, change the drilling rod operation procedure and still exist, its effect that improves operating efficiency is not remarkable.Because stroke is little, efficient is low, traditional roof-bolter propulsive mechanism can not adapt to tunnelling equipment and used simultaneously, appearance along with efficient helldriver structure, in order to improve the operating efficiency of roadway support, press for a kind of jumbolter propulsion plant airborne and that the roadway support operating efficiency is high that is fit to.

Summary of the invention:

The technical problem to be solved in the present invention is, a kind of improved anchor rod driller multiplication propulsion unit is provided, and it can increase the propelling stroke of jumbolter effectively, improves the supporting operating efficiency, to adapt to the supporting use of efficient associating heading equipment.

The technical scheme that the present invention solves the problems of the technologies described above employing is: anchor rod driller multiplication propulsion unit includes body frame, one-level advances oil cylinder, secondary advances oil cylinder, propeller and jumbolter group, all composition all is arranged on the body frame, one-level advances on the oil cylinder piston and is connected with propeller, be characterized in: be provided with guide rail structure between body frame and the propeller, be installed with secondary on the propeller and advance oil cylinder, secondary advances on oil cylinder and the propeller and is connected with multiplication mechanism respectively, multiplication mechanism is connected with the jumbolter group, is provided with guide rail structure between propeller and the jumbolter group.During bore operation, one-level advances cylinder action, drive the jumbolter group through propeller and finish first drilling rod propelling stroke, secondary advances cylinder action, drives the jumbolter group through multiplication mechanism and finishes quite second drilling rod propelling stroke of this oil cylinder piston stroke double length.

The present invention is in the secondary progradation, the amplification stroke function of mat multiplication mechanism, in limited lane space, the operation stroke of an actual installation drilling rod of jumbolter is increased greatly, overcome traditional jumbolter stroke defect of insufficient, can obviously improve the roadway support operating efficiency, and can adapt to the supporting use of efficient associating heading equipment, its corresponding guide rail structure then can be guaranteed the reliability of bore operation.
