And the steady rod structure of the present invention be by front slide 2 and tail skid 3 along slide plate sliding slot 12 straight line it is opposite slide open controlling and
Closure, can be such that the central opening 11 fully opens, so that large-sized stable disk be made to pass through, solve existing steady
Rod structure is not suitable for the problem of large scale stable disk passes through.
Further, the combined type of the raise boring machine opens and closes steady bar board plug structure further include: preceding steady rod oil cylinder 6 and rear steady
Rod oil cylinder 7, one end of steady rod oil cylinder 6 connects the front slide 2 before described, the other end connects the slide plate pedestal 1, steady after described
One end of rod oil cylinder 7 connects the tail skid 3, the other end connects the slide plate pedestal 1.
Fig. 2, Fig. 3 and Fig. 8 are please referred to, specifically in the present embodiment, the slide plate pedestal 1 includes top plate 13 and bottom plate
14, top plate 13 is similar U-shaped with bottom plate 14, and opening is oppositely arranged, it is possible thereby to form circular central opening 11.It is described steady
Rod oil cylinder 6 is connected between the top plate 13 and front slide 2, and when the preceding steady rod oil cylinder 6 elongation, the front slide 2 is forward
It opens, when steady rod oil cylinder 7 extends after described, tail skid 3 is opened backward, and thus front slide 2 and tail skid 3 are located remotely from each other, will
The central opening 11 fully opens, and guarantees that large-sized stable disk can pass through.When the preceding steady rod oil cylinder 6 retracts, institute
It states front slide 2 to slide back to backward, when rear steady rod oil cylinder 7 retracts, tail skid 3 is slid back to forward, so that front slide 2 and tail skid
3 is close to each other, until being close to, two steady bars watt 4 are close together at this time, realizes the stabilization function to drilling rod.When stable disk of unloading
When, the change of distance between front slide 2 and tail skid 3 in steady bar module section can be realized by the stroke of two oil cylinders of control,
The diameter for increasing centre bore, facilitates stable disk to pass through.
Further, the first rolling bearing units 22 are equipped at the top of the front slide 2, the tailpiece of the piston rod of steady rod oil cylinder 6 before described
It is installed on first rolling bearing units 22 equipped with the first oscillating bearing 61, and by the first pin shaft 62, the slide plate pedestal 1 pushes up
Portion is equipped with the first support 15, and the cylinder barrel end of steady rod oil cylinder 6 is equipped with second joint bearing 63 before described, and is pacified by the second pin shaft 64
Loaded on first support 15；3 bottom of tail skid is equipped with the second rolling bearing units 31, the piston of steady rod oil cylinder 7 after described
Rod end is equipped with third oscillating bearing 71, and is installed on second rolling bearing units 31 by third pin shaft 72, the slide plate bottom
1 bottom of seat is equipped with the second support 16, and the cylinder barrel end of steady rod oil cylinder 7 is equipped with the 4th oscillating bearing 73 after described, and passes through the 4th pin
Axis 74 is installed on second support 16.
Also referring to Fig. 5 and Figure 11, before described the both ends of steady rod oil cylinder 6 and rear steady rod oil cylinder 7 be all by pin shaft and
Oscillating bearing connects installation, and oscillating bearing has certain activity point of view, can prevent installation error and part's machining errors,
Lead to that cylinder piston rod is stuck and cannot flexibly stretch out retraction.Also, the present invention will be used to drive steady bar before front slide 2 oily
Cylinder 6 is set on top plate 13, will be used to drive the rear steady rod oil cylinder 7 of tail skid 3 to be set to 14 bottom of bottom plate, two oil cylinders are not done mutually
It relates to, design is reasonable.
Further, the combined type of the raise boring machine opens and closes steady bar board plug structure further include: 8 He of plate cylinder installation seat
Plate oil cylinder 9, the plate cylinder installation seat 8 are set to the front end of the front slide 2, described in the connection of described 9 one end of plate oil cylinder
Plate cylinder installation seat 8, the other end connect the plate 5.
The plate mounting base 8 is installed on the front slide 2 by bolt, plate oil cylinder 9 by the 5th pin shaft 91 with
Plate 5 connects, for driving the relatively described front slide 2 of plate 5 to slide.When plate oil cylinder 9 stretches out, in conjunction with engine reduced power case
Rotary motion, plate 5 slide backward, i.e., close to the drilling rod being located in the central opening 11, can smoothly be inserted into drilling rod card side,
Bar operation is unloaded to realize.
Further, the plate 5 is equipped with the rod aperture for connecting the plate oil cylinder 9, the rod aperture
Place is equipped with copper sheathing 93, and the 5th pin shaft 91 is equipped with and the oil nozzle 92 that is connected in copper sheathing 93.
Butter is filled by oil nozzle 92, for realizing lubrication anti-attrition.
Further, the slide plate sliding slot 12 includes the upper hopper chute 121 and gliding groove arranged side by side for being located at upper and lower position
122, the left and right end face of the front slide 2 is slideably flush-mounted in the upper hopper chute 121, the left and right end face of the tail skid 3
Slideably in the gliding groove 122.
Further, described referring to Fig. 10, the bottom of the front slide 2, which is downwardly projected, is formed with front slide pedestal 23
The rear end of front slide pedestal 23 is formed with the first arc convex 24 for installing steady bar watt 4；The front end of the tail skid 3 is formed
Have the second arc convex 32 for installing steady bar watt 4, when the front slide 2 and tail skid 3 close to close up when, second arc
Shape protrusion 32 and first arc convex 24 piece together circle.
The steady bar watt 4 is fixed on first arc convex 24 and the second arc convex 32 by the 6th pin shaft 41,
With the increase of guide hole operation time, different degrees of abrasion can occur for steady bar watt 4, when abrasion loss influences guide hole precision, tear open
The 6th pin shaft for playing fixed function down, can be convenient replacement.
Further, the rear end of the front slide 2 is equipped with front slide recess 25, and the top of the tail skid 3 projects upwards
It is formed with tail skid footstock 33, the front bulkhead of the tail skid footstock 33 is docked with the front slide recess 25；The tail skid 3
Front end be equipped with tail skid recess 34, the tail skid recess 34 docks with the aft bulkhead of the front slide pedestal 23.
So that tail skid footstock 33 can be along sliding before and after the bottom surface of the top plate 13 when tail skid 3 slides
Dynamic, when front slide 2 slides, front slide pedestal 23 can slide back and forth along the top surface of the bottom plate 14, also, when advancing slip
When plate 2 and tail skid 3 are drawn close, when steady bar watt 4 is fitted in drilling rod periphery, the aft bulkhead and tail skid footstock 33 of front slide 2 can bases
This fastening, the front bulkhead and front slide pedestal 23 of tail skid 3 can fasten substantially, so that this structure more consolidates firm, raising machine
Tool intensity.
Further, the intermediate recess of the front slide 2 is formed with plate accommodation groove 26, and the two of the plate accommodation groove 26
Side is recessed inwardly to form the plate sliding slot 21；The steady bar watt 4 is located at 21 lower section of plate sliding slot.
When thereby ensuring that front slide 2 and tail skid 3 close up, the plate 5 and steady bar watt 4 are located at total
Upper and lower position, it is non-interference, also, board plug structure is mounted in steady rod structure by the present invention, and total is compact to design, subtracts
The space occupied is lacked.
Further, referring to Fig. 7, the rear end of the upper hopper chute 121 is equipped with front slide limited block 123；Referring to Fig. 8,
