As described in aforementioned background art, in fully-mechanized mining working after longtime running, hydraulic support screens hydraulic support
The pin hole of beam will appear abrasion condition, and hydraulic support shield beam includes that multiple tracks is parallel to each other and strengthening version separated by a distance,
Pin hole is provided in stiffening plate, the pin hole in adjacent two pieces of stiffening plates is actually concentric.The abrasion ordinary circumstance of pin hole
Under be the big one end serious wear of stress, one section of small abrasion of stress is lighter, the small one end of ordinary circumstance lower stress substantially not why
Abrasion, the pin hole 14 after thus causing abrasion typically become the small taper hole shape in the big one end in one end.Repair one
As be the through-hole that the pin hole 14 after abrasion is repaired into the general size in both ends again with Boring machine.Have one around general pin hole
A circular bosses for protruding from stiffening plate certain altitude, script effect are to extend the length of pin hole, and play and reinforce pin hole stress
Effect.
As shown in figure 16, Figure 16 is the repairing and boring machine of one embodiment of the present invention to positive axis and to just covering to just
Scheme of installation.In some embodiments, the real work method of the repairing and boring machine of hydraulic support shield beam of the invention
It is as follows:
Firstly, two pieces of positioning plates 1 are sticked in two pieces of adjacent stiffening plates 15 respectively in the opposite form of positioning sleeve 22.
Then two guide rods 6 are first threaded through in the moving hole 17 of guide sleeve 19 of positioning disk 4, and by the both ends of every guide rod 6
It is inserted into the location hole 21 of positioning plate 1 respectively.Positive axis 35 will be inserted into and be covered in 36 to positive later, and positive set 36 will be arranged in and be led
To 4 center of disk in positive mounting hole 16, to the both ends of positive axis 35 also cross the abrasion in adjacent two pieces of stiffening plates 15 after
Small end (the note: identical with the internal diameter to positive mounting hole 16 to the outer diameter of positive set 36, and using small―gap suture cooperation of pin hole 14；To just
The diameter of axis 35 is identical as the end diameter of pin hole 14 after abrasion, while also identical as the diameter of bore to positive set 36, and
Cooperated using small―gap suture).It is guarantee positioning disk 4 to positive mounting hole 16 and adjacent two pieces to positive axis 35 and to the effect of positive set 36
The small end almost coaxial of pin hole 14 after abrasion in stiffening plate 15.The fastening section 62 of guide rod 6 is blocked with tool (such as spanner)
On fang platform 63, rotational fastener section 62 is until the both ends of two guide rods 6 are held out against between adjacent two pieces of stiffening plates 15.So
The fastening bolt 8 on positioning plate 1 is screwed with tool again afterwards, is allowed to hold out against with the periphery of the circular bosses 151 in stiffening plate 15, directly
It is completely fixed on circular bosses 151 to positioning plate 1, and until guaranteeing that positioning disk 4 can be moved freely along guide rod 6 simultaneously.It is complete
After extract out to positive axis 35 and to positive set 36.The installation bolt 5 of hydraulic motor 7 that front end assembles Qian type boring cutter 2 and tool apron 3 is led to
The tapped through hole 18 crossed on positioning disk 4 is mounted on in positive mounting hole 16.Screw 10 is installed in the another of 7 rear end of hydraulic motor again
In fabrication hole 12 in one piece of stiffening plate 15,10 shape of screw is formed by stacking by two cylinders, and small stair is embedded in fabrication hole 12,
The diameter of big step is greater than fabrication hole 12 and is pressed on the metope of another piece of strengthening version, from the small stair end of screw 10 by lead screw 9
It is screwed into screw 10, and the front end of lead screw 9 is supported to the center of 7 rear end of hydraulic motor.Connect hydraulic motor 7 and hydraulic
Pumping plant 34, starting hydraulic power unit 34 makes hydraulic motor 7 that tool apron 3 and Qian type boring cutter 2 be driven to rotate, while 9 other end of rotating threaded shaft
Handwheel 11, lead screw 9 is immovable because screw 10 is limited by another piece of stiffening plate 15, therefore lead screw 9 can only move forward,
It pushes hydraulic motor 7 and tool apron 3 and Qian type boring cutter 2 as positioning disk 4 slides on guide rod 6 simultaneously, and then completes abrasion
The bore hole reparation of pin hole 14 afterwards.After pin hole 14 after one abrasion repairs completion, hydraulic motor 7 is exchanged to positioning disk 4
The other side install.Because the front end of hydraulic motor 7 has positioning round table, the diameter of positioning round table is with positioning disk 4 to just
The diameter of mounting hole 16 is identical, and has multiple positions and quantity in the subsequent mounting disc of 7 positioning disc of hydraulic motor and lead
To the corresponding bolt hole of tapped through hole 18 of disk 4, when due to repairing the pin hole 14 after first abrasion two pieces of positioning plates 1 and
Positioning disk 4 is completed to positive, exchanges hydraulic motor 7 to the other side of positioning disk 4 equally also can guarantee that it is in pair at this time
Positive status.Lead screw 9 and screw 10 are also exchanged to the strengthening version 15 of other side simultaneously, then carry out the pin after another abrasion
The reparation in hole 14.
It does not need to wear in conclusion the repairing and boring machine of hydraulic support shield beam of the invention has the advantage that
Hydraulic support shield beam afterwards is transported to ground from underground and is repaired, and is in underground site using repairing and boring machine of the invention
Achievable repair.It eliminates 30 tons or so of the hydraulic support of weighing to be promoted from hundred meters of undergrounds to ground, then transports underground back
The complicated working links such as installation, cost saved man power and material, and be greatly improved repair efficiency.
The aforementioned description to specific exemplary embodiment of the invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explaining specific principle of the invention and its actually answering
With so that those skilled in the art can be realized and utilize a variety of different exemplary implementation schemes of the invention and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
