Detailed description of the invention

Technical scheme is described further below, but claimed scope is not limited to In described.

The anti-rotation piston movement of a kind of large ocean application apparatus as shown in Figures 1 to 5 is secondary Cylinder, including duct cylinder 1, work cylinder 5, spacing cylinder 6;Described duct cylinder 1, work Make cylinder 5, the end face of spacing cylinder 6 is provided with annular connecting plate 12, described duct cylinder 1, Work cylinder 5 and spacing cylinder 6 are same successively by bolt kit 11 stationary annular connecting plate 12 The heart connects fixing, and the home position of duct cylinder 1 and spacing cylinder 6 has center guide shaft 4 to run through solid Fixed;On described spacing cylinder 6 by work cylinder 5 one end end face on be fixed with multiple the most equal The spacing cushion socket 15 of even distribution.

Arrange porose on described duct cylinder 1, hole on corresponding duct cylinder 1 on spacing cylinder 6 Position is provided with spacing guide pin bushing 17, and spacing guide pin bushing 17 is interspersed with spacing cushion socket 15, spacing Guide pin bushing 17 upper cover is equipped with guide pin bushing gland 16.

Described work cylinder 5 is connected into cylinder by eight pieces of cylinder guide rails 9 and the zigzag weld of eight blocks of arc plates 14, Cylinder guide rail 9 outwardly, equipped with guide rail bar 8 in cylinder guide rail 9;Work cylinder 5 is outer vertically It is welded with four pieces of ring web plates 13 successively.

Described spacing cushion socket 15 quantity is four.

Described annular connecting plate 12 edge is provided with multiple hoisting ring 10.

The described hoisting ring 10 quantity on each piece of annular connecting plate 12 is four.

Guide pin bushing gland 16 on described spacing cylinder 6 and spacing guide pin bushing 17 are fitted with pulling shaft 3.

When actually used, in 8 cylinder guide rails 9 of work cylinder 5, it is respectively charged into guide rail bar 8 After, duct cylinder 1 is connected firmly with work cylinder 5 bolt kit 11;Pulling shaft 3 is worn After having installed the spacing cylinder 6 of spacing guide pin bushing 17 and guide pin bushing gland 16, pulling shaft 3 two ends are divided It is not connected firmly in piston 2 and link 7, center guide shaft 4 is inserted spacing cylinder through piston 2 In the center positioning hole of 6, form an overall connection framework, this is connected framework and loads work Make in cylinder 5, and after fixing for center guide shaft 4 end is inserted the center positioning hole of duct cylinder 1, Spacing cylinder 6 is connected firmly with work cylinder 5 bolt kit 11;The spacing nearly piston of cylinder 6 One end circumference uniform distribution installs 4 spacing cushion sockets 15, in order to limit the stroke of piston 3.Seating nipple Body 5 is by the annular connecting plate 12 at two ends and 9,8 arc plates 14 of 8 cylinder guide rails and 4 ring web plates 13 are welded, due to the internal diameter of work cylinder 5 welding bigger than the external diameter of piston 2 matrix (15~ 30) mm, and this gap seals leaf by the corrosion resistant arc of high resiliency installed on the piston 2 Sheet compensates, and has both ensured the sealing requirements that piston 2 runs, by ensure that piston barrel Stiffness requirement;8 roller one_to_one corresponding at piston 2 two ends circumference uniform distribution are arranged on cylinder and lead Guide rail bar 8 in rail 9, in order to preferably to reduce the resistance that piston runs.

Based on above-mentioned, it is however generally that cylinder of the present invention is divided into four part compositions, and a part is duct Cylinder, by high strength steel welding processing molding, duct cylinder circumference uniform distribution four work duct, It is connected in the middle part of end at it with work cylinder center guide shaft mounting-positioning holes is set, duct cylinder two ends Annular connecting plate can ensure that the strength and stiffness requirement that its two ends connect.Part II is work Make cylinder, also by high strength steel welding processing molding, the annular connecting plate endoporus at cylinder two ends Through machining, and processing the mounting groove of the cylinder guide rail of 8 circumference uniform distributions, cylinder is led Rail inside groove and profile are through machining molding;Arc plate internal diameter bigger than piston matrix external diameter (15~ 30) mm, arc plate lower end processes the passage for fluid turnover, and arc plate arc length protrudes cylinder Guide rail, forms the limited step of guide rail bar, and arc plate reclines the endoporus of two ends annular connecting plate, and 8 Root cylinder guide rail by 8 uniform mounting grooves of annular connecting plate by the annular connecting plate at two ends and Arc plate is solidified into an entirety, uniform several roads, axial stage casing ring web plate, both ensure that work cylinder Strength and stiffness, the annular connecting plate at two ends process bolt kit connect by hole, can With easily by duct cylinder, spacing cylinder and its be attached.Part III is position-limiting drum Body, by high strength steel welding processing molding, spacing cylinder circumference uniform distribution four radially spacing hole, Installing sliding sleeve in it, piston pulling shaft passes sliding sleeve, not only can ensure that axle at piston running Smooth and easy to run, it is also possible to limit relatively rotating between piston and cylinder, it is ensured that piston with The radial orientation of cylinder is the most consistent;It is connected in the middle part of end at it with work cylinder center guide shaft is set Mounting-positioning holes, the annular connecting plate of spacing cylinder upper end can ensure that the intensity that its two ends connect And rigidity requirement, spacing with the connection extreme direction circumference uniform distribution 4 of work cylinder at spacing cylinder Cushion socket, in order to limit the axial displacement of piston.Guide shaft centered by Part IV, center guide shaft Matrix uses high strength steel manufacture, and outer surface of matrix cladding thickness is the resistance to of (8~10) mm Mill, resistant material, both ensured the steel of center guide shaft, requirement of strength, it is also ensured that reduces The resistance that piston runs, also can solve the anticorrosive problem of guide shaft simultaneously well.
