Description
Technical field
The utility model relates to a kind of pricker device that unloads, and especially relates to a kind of auxiliary pricker device that unloads of raise boring machine.
Background technology
At present, domestic mine has begun to promote this Fully-mechanized upraise method of raise boring machine, and progressively replaces the dangerous high quick-fried method of the common cutter of courtyard, makes drivage efficiency, one-tenth well quality be improved, and operating environment and labor strength improve.
But existing raise boring machine is not provided with the auxiliary pricker device that unloads when drilling well; Only rely on rotary motor to reverse and unload drilling rod, unload when motionless, often need artificial wheel sledgehammer when running into the screw thread tension; The loose drill rod thread of shake adopts the extension bar spanner more earlier, unloads with manual work; Not only take people, time-consuming, effort, the personal safety accident also takes place easily.
The utility model content
The utility model technical problem to be solved is, provides a kind of mechanization degree high, unloads that to bore moment of torsion big, the auxiliary pricker device that unloads of the raise boring machine of reliable operation.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of auxiliary pricker device that unloads of raise boring machine; Comprise unload pricker device base plate, unload the pricker oil cylinder, waist shape lever, bearing pin cover plate, ball screw, ratchet, extension spring and ratchet, the said pricker device base plate that unloads is fixed on the base plate of deceleration box, said lower end of unloading the pricker oil cylinder is hinged on unloads on the outstanding ear seat in the pricker device base plate lower right corner; Said upper end of unloading the pricker oil cylinder is hinged on the right-hand member of waist shape lever; The middle part of said waist shape lever is hinged on the boss that unloads pricker device base plate top through main shipping and reselling on another market, and the left end of said waist shape lever is hinged through detent pin and ratchet, and said bearing pin cover plate is positioned at main shipping and reselling on another market and goes up and be fixedly connected with the boss that unloads pricker device base plate top; Said ball screw is screwed on the boss that unloads pricker device base plate top; Be integrally formed with unloading pricker device base plate, an end of said extension spring links to each other with ratchet, the other end with unload pricker device base plate and link to each other; Said ratchet is fixed on the chuck, is integrally formed with chuck.
The utility model compact conformation, easy and simple to handle, mechanization degree is high, and can realize unloading automatically bar or the remote control bar of unloading unloads that to bore moment of torsion big, reliable operation; When raise boring machine unloads drilling rod, utilize the utility model, can increase and unload loose drill rod thread moment of torsion tool, to unload the connecting thread that connects tension between the loose drilling rod, result of use is good.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is a vertical view embodiment illustrated in fig. 1;
Fig. 3 is the sketch map that unloads the pricker state that is in embodiment illustrated in fig. 1;
Fig. 4 is a perspective view embodiment illustrated in fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
With reference to accompanying drawing, present embodiment comprise unload pricker device base plate 1, unload pricker oil cylinder 3, waist shape lever 4, bearing pin cover plate 5, ball screw 8, ratchet 9, extension spring 11 and ratchet 12; The said pricker device base plate 1 that unloads is fixed on the base plate of deceleration box 13 through soket head cap screw 2; Said lower end of unloading pricker oil cylinder 3 is hinged on unloads on the outstanding ear seat in pricker device base plate 1 lower right corner, and the upper end is hinged on the right-hand member of waist shape lever 4; The middle part of said waist shape lever 46 is hinged on the boss that unloads pricker device base plate 1 top through main shipping and reselling on another market, and the left end of said waist shape lever 4 is hinged through detent pin 10 and ratchet 9; Said bearing pin cover plate 5 is positioned at main shipping and reselling on another market on 6, and is fixed on the boss that unloads pricker device base plate 1 top through cover plate set bolt 7,6 gets loose to prevent main shipping and reselling on another market; Said ball screw 8 is screwed on the boss that unloads pricker device base plate 1 top, is integrally formed with pricker device base plate 1; One end of said extension spring 11 links to each other with ratchet 9 through hanging the spring earrings, the other end through extension spring earrings with unload pricker device base plate 1 and link to each other; Said ratchet 12 is fixed on the chuck, is integrally formed with chuck, rotates with the reduction box main shaft.
Operating principle: when the piston rod that unloads pricker oil cylinder 3 upwards moved, ratchet 9 moved down under waist shape lever 4 drives, and under the effect of extension spring 11, ratchet 9 inserts in the ratchet of ratchet 12 automatically, and ratchet 12 is turned clockwise, and produces the moment of torsion that unloads loose drilling rod screw thread; When the piston rod that unloads pricker oil cylinder 3 moved downwards, ratchet 9 rises under waist shape lever 4 drives, and was final; The afterbody of ratchet 9 can be run into ball screw 8; Force ratchet 9 to be rotated counterclockwise, make ratchet 9 break away from the ratchet of ratchet 12, free the rotation restriction of 9 pairs of ratchets 12 of ratchet.
