The large-cylinder-diameter hydraulic stand column vertical cylinder detaching machine has the advantage that the problem that in the detaching process of a large-cylinder-diameter hydraulic stand column with the inner diameter larger than 360 mm, a guiding sleeve and a stand column cylinder barrel cannot be detached easily because of deformation in the using process is solved.
Description
Technical field
The present invention relates to internal diameter is 360mm and above large-diameter hydraulic vertical prop, especially relates to that large-diameter hydraulic vertical prop is vertical tears cylinder machine open.
Background technology
Hydraulic vertical prop belongs to the major impetus parts of hydraulic support, is the capital equipment of lifting, roof supporting.The cost of hydraulic vertical prop is the parts that hydraulic support substance cost is the highest.Therefore, in hydraulic support overhaul process, hydraulic vertical prop outer shell and middle cylinder can not be scrapped easily, are that overhaul is worth one of the highest parts.
At present, in dismounting hydraulic vertical prop process, especially for internal diameter 360mm and above large-diameter hydraulic vertical prop, the detaching equipment of the thrust that can provide enough large is lacked.When tearing motionless hydraulic vertical prop fairlead open, outer cylinder and middle cylinder barrel can only be scrapped.Chinese patent CN102294584B discloses a kind of column horizontal and tears cylinder machine open, this column horizontal tears cylinder machine open in column unloading process, gravity can make fairlead sagging in unloading process, easily grind and hinder cylinder barrel and fairlead sealing surface, its thrust is maximum simultaneously can only reach 100,000 Nm, and just one-sided loading, easily cause fairlead one-sided stressed rear stuck, make dismounting difficulty larger.
Summary of the invention
The object of the invention is to provide that a kind of large-diameter hydraulic vertical prop is vertical tears cylinder machine open.
For achieving the above object, the present invention takes following technical proposals:
Large-diameter hydraulic vertical prop of the present invention is vertical tears cylinder machine open, comprises frame, and described frame by top board, base plate, and is fixed on four column jeckets between described top board and base plate, and the cylinder bottom holder be fixed on base plate is formed; Top board, base plate offer the guide pillar hole with described cylinder bottom holder coaxial line; Be positioned at described top board guide pillar hole place and be provided with ratchet, described ratchet is provided with guide seat structure, and described guide holder is placed in top board guide pillar hole with dynamic fit system; Top board is symmetrical in ratchet axis and is horizontally disposed with two hydraulic jack controlled by hydraulic power unit, the cylinder bottom of described two hydraulic jack is hinged with top board respectively, and the piston rod end of two hydraulic jack is hinged with cutting somebody's hair of matching with the ratchet gear teeth respectively; Dismounting driver plate is provided with in the wheel bore of ratchet, the endoporus of described dismounting driver plate is the cubic circular hole adapted with hydraulic vertical prop fairlead flange profile, uniformly on dismounting driver plate outer peripheral face be provided with at least four lugs, uniformly on the wheel bore face of ratchet offer at least four ear grooves adapted with described lug.
Be fixed on four column jeckets between described top board and base plate for being symmetrical arranged.
The invention has the advantages that and solve internal diameter at 360mm and above large-diameter hydraulic vertical prop in unloading process, fairlead and column cylinder owing to producing distortion and stuck not easily detachable problem in use procedure, fairlead uniform force in unloading process and can not because of one-sided stressed and stuck; And do not exist because gravity causes that fairlead is sagging in unloading process grinds the phenomenon of hindering cylinder barrel and fairlead sealing surface, greatly save column and reprocess cost.Simultaneously simple, the simple operation of structure of the present invention.

Detailed description of the invention
As Figure 1-5, large-diameter hydraulic vertical prop of the present invention is vertical tears cylinder machine open, comprise frame, described frame is by top board 1, base plate 2, with symmetry is fixed on four column jeckets 3 between top board 1 and base plate 2, and fixing cylinder bottom holder 4 is on a base plate 2 formed, four column jeckets 3 all adopt steel pipe with weight reduction and cost; Top board 1, base plate 2 offer the guide pillar hole of the same axis 5 with cylinder bottom holder 4; Be positioned at top board guide pillar hole place and be provided with ratchet 6, ratchet 6 is provided with guide holder 7 structure for bottom, and guide holder 7 is placed in top board guide pillar hole with dynamic fit system; The axis horizontal that top board 1 is symmetrical in ratchet 6 is provided with two hydraulic jack controlled by hydraulic power unit 8.1,8.2, the cylinder bottom of two hydraulic jack 8.1,8.2 is hinged with top board 1 respectively, the piston rod end of two hydraulic jack 8.1,8.2 be hinged with respectively match with the ratchet gear teeth cut somebody's hair 9.1,9.2; Dismounting driver plate 10 is provided with in the wheel bore of ratchet 6, the endoporus of dismounting driver plate 10 is the cubic circular hole adapted with the fairlead flange profile of hydraulic vertical prop 11, uniformly on dismounting driver plate 10 outer peripheral face be provided with six lugs 12, uniformly on the wheel bore face of ratchet 6 offer six ear grooves adapted with lug 12.
Operating procedure of the present invention is summarized as follows:
Step 1, the hydraulic vertical prop 11 of dismounting will be needed to utilize driving vertical lifting in guide holder 7, and vertically decline, the ear lobe being limited hydraulic vertical prop 11 cylinder bottom both sides by cylinder bottom holder 4 makes it not rotate;
Step 2, six lugs 12 of uniform setting on dismounting driver plate 10 outer peripheral face are put into ratchet 6 wheel bore face on the uniform ear groove offered, make the cubic circle hole sleeve of dismounting driver plate 10 be contained in the fairlead flange outer peripheral face of hydraulic vertical prop 11;
Step 3,9.1,9.2 ends of cutting somebody's hair that two hydraulic jack 8.1,8.2 piston rod ends are hinged are respectively placed in the teeth groove of ratchet 6, synchronously drive two hydraulic jack 8.1,8.2 to promote ratchet by hydraulic power unit to be rotated counterclockwise, drive the fairlead of hydraulic vertical prop 11 to rotate by dismounting driver plate 10, realize fairlead and once rotate;
After step 4, two hydraulic jack 8.1,8.2 piston rods all stretch out, the teeth groove of 9.1,9.2 ends and ratchet 6 of making to cut somebody's hair departs from, then two hydraulic jack 8.1,8.2 piston rods are regained, step 3 is repeated in the teeth groove again 9.1,9.2 ends of cutting somebody's hair being placed in ratchet 6, until disassemble out by fairlead, cylinder process torn open by the fairlead completing hydraulic vertical prop 11.
The single hydraulic jack of the present invention can provide the thrust of 480KN; The ratchet 6 effectively arm of force is 1000mm, therefore the moment size that the present invention can provide is as follows: 480 × 1000 × 2=960000Nm.
