Specific implementation mode
The specific implementation mode of the present invention is made further detailed by the description to case study on implementation below against attached drawing
Explanation.
The present invention is a kind of dismounting of hydraulic support column threaded guide sleeve and assembly tool, for making when coal mine operation
With being divided into fixed disk, rotating disk and auxiliary spanner three parts.
As shown in Figure 1, it is assumed that column B is column to be repaired, and fixed disk 1 is fixed on column A, and fixed disk 1 is seperated half
Ring structures are placed the guide sleeve of fixed disk chuck 12 and column A in the same plane, and fixed disk chuck jaws 14 is made to block
In the card slot of guide sleeve, the both ends of each semi-ring are equipped with gusset piece 7, then use high-strength bolt 8 and high strength nut 9
Gusset piece is fastened, two semi-rings is made to form an entirety.Rotating disk 5 is integral ring-shaped structure, is needed before installation to be repaired vertical
Column B and hydraulic support top beam body connecting link pin disengage, and then column B piston rods are contracted to can be rotating disk 5 from piston rod top
End cap enters, is installed to guide sleeve position, and the guide sleeve of rotating disk chuck 18 and column B are placed in the same plane, made simultaneously
Rotating disk chuck jaws 21 are stuck in guide sleeve card slot.After fixed disk 1 and rotating disk 5 are installed in place, the cylinder of hydraulic jack 4
Seat 11 is fixed on by axis pin 2 and split pin 3 in hydraulic jack topmast seat 6, then 10 end of piston rod of hydraulic jack 4
It is placed in the cavity position formed between block plate 19 under block plate 17, rotating disk in rotating disk jacking block 16 and rotating disk, ensures rotation
Direction of rotation is counterclockwise after 5 stress of disk；Then so that its piston rod 10 is stretched out to 4 cavity of resorption feed flow of hydraulic jack and pushes rotating disk
5 counterclockwise rotate to unclamp column B guide sleeves, when the piston rod stroke of hydraulic jack 4 is fully extended, then give hydraulic pressure
The epicoele feed flow of jack 4 makes its piston rod 10 withdraw completely, the piston rod end of jack 4 is then placed in rotation again
Disk 5 it is next（Or choose suitable position）16 position of rotating disk jacking block repeats above-mentioned action, be finally reached remove completely it is vertical
The purpose of column B guide sleeves.During being somebody's turn to do, fixed disk reinforces disk 13, fixed disk anti-dumping block 15 and rotating disk anti-dumping block 20
Firm effect is played, is not tilted after making 5 stress of fixed disk 1 and rotating disk；The anti-fall block 22 of rotating disk is revolved in column B guide sleeves
Loose process, which is crossed, can prevent rotating disk 5 from falling off, while the screw thread between column A guide sleeves and cylinder body is complete locking state, in liquid
Its stress is coupling mechanism force when pressing jack 4 that rotating disk 5 is pushed to rotate, and can play the role of support.
Conversely, after column B replaces the completions such as sealing ring, dustband reparation, as shown in Figure 2：In fixed disk 1 and hydraulic pressure thousand
In the case that jin top 4 keeps original state, rotating disk 5 is installed on column B guide sleeves to be assembled and rotating disk chuck jaws
21 are stuck in the card slot of column B guide sleeves；Then the piston rod end of hydraulic jack 4 is placed in rotating disk jacking block 16 and rotation
The cavity position formed between block plate 19 under block plate 17, rotating disk on turntable, direction of rotation is up time after ensureing 5 stress of rotating disk
Needle then makes its piston rod 10 stretch out and rotating disk 5 is pushed to be rotated clockwise to screw to the cavity of resorption feed flow of hydraulic jack 4
Column B guide sleeves when the piston rod stroke of hydraulic jack 4 is fully extended, then to the epicoele feed flow of hydraulic jack 4, make
Its piston rod is withdrawn completely, and it is next that the piston rod end of jack 4 is then placed in rotating disk 5 again（Or choose suitable position
It sets）16 position of rotating disk jacking block repeats above-mentioned action, is finally reached the purpose of locking column B guide sleeves completely.Column at this time
Screw thread between A guide sleeves and cylinder body is complete locking state, and when hydraulic jack 4 pushes rotating disk 5 to rotate, its stress is
Coupling mechanism force can play the role of support.
Attached drawing 3 show auxiliary spanner, including pinch bar 25, wrench body 23 and the spanner card being arranged on the inside of spanner
Pawl 24.When guide sleeve of stand column to be repaired starts dismounting, the screw thread between guide sleeve and column cylinder body is complete locking state, need to use liquid
Pressure jack 4 first loosens guide sleeve, and pine blocks guide sleeve using auxiliary spanner 23 afterwards to a certain extent and carries out mutual disassembly, together
When steel pipe can be lengthened on 25 position of pinch bar covers increasing the arm of force to reduce labor intensity.Dress is completed in column reparation
Timing first carries out artificial pre- locking to guide sleeve with auxiliary spanner, then uses hydraulic jack 4 to guide sleeve according to the method described above
It is locked completely.During this, auxiliary spanner plays the role of improving working efficiency.
Hydraulic support column threaded guide sleeve underground coal mine of the present invention dismounting, assembly tool, reasonable design is simple in structure,
Simple operation can securely and reliably use under underground coal mine confined condition, be suitble to the vertical of plurality of specifications by changing design size
The dismounting of column guide sleeve, assembly reduce fund input, the cost occupancy of production process, save human and material resources and financial resources, carry
High production efficiency.
The present invention is exemplarily described above in conjunction with attached drawing, but the present invention is not limited to aforesaid way, only
It wants the improvement of the various unsubstantialities of methodology and technical solution progress using the present invention or directly applies to other occasions
, land in protection scope of the present invention.
